-# This should include all the same exceptions that we use for core files.
-#
-# In Spack packages, we also allow the single `from spack import *`
-# wildcard import and dependencies can set globals for their
-# dependents. So we add exceptions for checks related to undefined names.
-#
-# Note that we also add *per-line* exemptions for certain patterns in the
-# `spack flake8` command.  This is where F403 for `from spack import *`
-# is added (because we *only* allow that wildcard).

+=======
+Analyze
+=======
+
+
+The analyze command is a front-end to various tools that let us analyze
+package installations. Each analyzer is a module for a different kind
+of analysis that can be done on a package installation, including (but not
+limited to) binary, log, or text analysis. Thus, the analyze command group
+allows you to take an existing package install, choose an analyzer,
+and extract some output for the package using it.
+
+
+-----------------
+Analyzer Metadata
+-----------------
+
+For all analyzers, we write to an ``analyzers`` folder in ``~/.spack``, or the
+value that you specify in your spack config at ``config:analyzers_dir``. 
+For example, here we see the results of running an analysis on zlib:
+
+.. code-block:: console
+
+    $ tree ~/.spack/analyzers/
+    └── linux-ubuntu20.04-skylake
+        └── gcc-9.3.0
+            └── zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2
+                ├── environment_variables
+                │   └── spack-analyzer-environment-variables.json
+                ├── install_files
+                │   └── spack-analyzer-install-files.json
+                └── libabigail
+                    └── spack-analyzer-libabigail-libz.so.1.2.11.xml
+    
+
+This means that you can always find analyzer output in this folder, and it
+is organized with the same logic as the package install it was run for. 
+If you want to customize this top level folder, simply provide the ``--path``
+argument to ``spack analyze run``. The nested organization will be maintained
+within your custom root.
+
+-----------------
+Listing Analyzers
+-----------------
+
+If you aren't familiar with Spack's analyzers, you can quickly list those that 
+are available:
+
+.. code-block:: console
+
+    $ spack analyze list-analyzers
+    install_files            : install file listing read from install_manifest.json
+    environment_variables    : environment variables parsed from spack-build-env.txt
+    config_args              : config args loaded from spack-configure-args.txt
+    abigail                  : Application Binary Interface (ABI) features for objects
+
+
+In the above, the first three are fairly simple - parsing metadata files from
+a package install directory to save
+
+-------------------
+Analyzing a Package
+-------------------
+
+The analyze command, akin to install, will accept a package spec to perform
+an analysis for. The package must be installed. Let's walk through an example
+with zlib. We first ask to analyze it. However, since we have more than one
+install, we are asked to disambiguate:
+
+.. code-block:: console
+
+    $ spack analyze run zlib
+    ==> Error: zlib matches multiple packages.
+      Matching packages:
+        fz2bs56 zlib@1.2.11%gcc@7.5.0 arch=linux-ubuntu18.04-skylake
+        sl7m27m zlib@1.2.11%gcc@9.3.0 arch=linux-ubuntu20.04-skylake
+      Use a more specific spec.
+
+
+We can then specify the spec version that we want to analyze:
+
+.. code-block:: console
+
+    $ spack analyze run zlib/fz2bs56
+
+If you don't provide any specific analyzer names, by default all analyzers 
+(shown in the ``list-analyzers`` subcommand list) will be run. If an analyzer does not
+have any result, it will be skipped. For example, here is a result running for
+zlib:
+
+.. code-block:: console
+
+    $ ls ~/.spack/analyzers/linux-ubuntu20.04-skylake/gcc-9.3.0/zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2/
+    spack-analyzer-environment-variables.json
+    spack-analyzer-install-files.json
+    spack-analyzer-libabigail-libz.so.1.2.11.xml
+
+If you want to run a specific analyzer, ask for it with `--analyzer`. Here we run
+spack analyze on libabigail (already installed) _using_ libabigail1
+
+.. code-block:: console
+
+    $ spack analyze run --analyzer abigail libabigail
+
+
+.. _analyze_monitoring:
+
+----------------------
+Monitoring An Analysis
+----------------------
+
+For any kind of analysis, you can
+use a `spack monitor <https://github.com/spack/spack-monitor>`_ "Spackmon"
+as a server to upload the same run metadata to. You can
+follow the instructions in the `spack monitor documentation <https://spack-monitor.readthedocs.org>`_
+to first create a server along with a username and token for yourself.
+You can then use this guide to interact with the server.
+
+You should first export our spack monitor token and username to the environment:
+
+.. code-block:: console
+ 
+    $ export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+    $ export SPACKMON_USER=spacky
+
+
+By default, the host for your server is expected to be at ``http://127.0.0.1``
+with a prefix of ``ms1``, and if this is the case, you can simply add the
+``--monitor`` flag to the install command:
+
+.. code-block:: console
+
+    $ spack analyze run --monitor wget
+

+Different from other packages, ``CudaPackage`` does not represent a build system.
+Instead its goal is to simplify and unify usage of ``CUDA`` in other packages by providing a ` mixin-class <https://en.wikipedia.org/wiki/Mixin>`__.
 
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Provided variants and dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+You can find source for the package at
+`<https://github.com/spack/spack/blob/develop/lib/spack/spack/build_systems/cuda.py>`__.
 
-``CudaPackage`` provides ``cuda`` variant (default to ``off``) to enable/disable
-``CUDA``, and ``cuda_arch`` variant to optionally specify the architecture.
-It also declares dependencies on the ``CUDA`` package ``depends_on('cuda@...')``
-based on the architecture as well as specifies conflicts for certain compiler versions.
+^^^^^^^^
+Variants
+^^^^^^^^
+
+This package provides the following variants:
+
+* **cuda**
+
+  This variant is used to enable/disable building with ``CUDA``. The default
+  is disabled (or ``False``).
+
+* **cuda_arch**
+
+  This variant supports the optional specification of the architecture.
+  Valid values are maintained in the ``cuda_arch_values`` property and
+  are the numeric character equivalent of the compute capability version
+  (e.g., '10' for version 1.0). Each provided value affects associated
+  ``CUDA`` dependencies and compiler conflicts.
+
+  GPUs and their compute capability versions are listed at
+  https://developer.nvidia.com/cuda-gpus .
+
+^^^^^^^^^
+Conflicts
+^^^^^^^^^
+
+Conflicts are used to prevent builds with known bugs or issues. While
+base ``CUDA`` conflicts have been included with this package, you may
+want to add more for your software.
+
+For example, if your package requires ``cuda_arch`` to be specified when
+``cuda`` is enabled, you can add the following conflict to your package
+to terminate such build attempts with a suitable message:
+
+.. code-block:: python
+
+    conflicts('cuda_arch=none', when='+cuda',
+              msg='CUDA architecture is required')
+
+Similarly, if your software does not support all versions of the property,
+you could add ``conflicts`` to your package for those versions.  For example,
+suppose your software does not work with CUDA compute capability versions
+prior to SM 5.0 (``50``).  You can add the following code to display a
+custom message should a user attempt such a build:
+
+.. code-block:: python
+
+    unsupported_cuda_archs = [
+        '10', '11', '12', '13',
+        '20', '21',
+        '30', '32', '35', '37'
+    ]
+    for value in unsupported_cuda_archs:
+        conflicts('cuda_arch={0}'.format(value), when='+cuda',
+                  msg='CUDA architecture {0} is not supported'.format(value))
+
+^^^^^^^
+Methods
+^^^^^^^
+
+This package provides one custom helper method, which is used to build
+standard CUDA compiler flags.
+
+**cuda_flags**
+
+    This built-in static method returns a list of command line flags 
+    for the chosen ``cuda_arch`` value(s).  The flags are intended to
+    be passed to the CUDA compiler driver (i.e., ``nvcc``).
+
+    This method must be explicitly called when you are creating the
+    arguments for your build in order to use the values.
 
 ^^^^^
 Usage
 ^^^^^
 
-In order to use it, just add another base class to your package, for example:
+This helper package can be added to your package by adding it as a base
+class of your package.  For example, you can add it to your
+:ref:`CMakePackage <cmakepackage>`-based package as follows:
 
 .. code-block:: python
+   :emphasize-lines: 1,7-16
 
-    class MyPackage(CMakePackage, CudaPackage):
+    class MyCudaPackage(CMakePackage, CudaPackage):

             spec = self.spec
+            args = []
+            ...
             if '+cuda' in spec:
-                options.append('-DWITH_CUDA=ON')
-                cuda_arch = spec.variants['cuda_arch'].value
+                # Set up the cuda macros needed by the build
+                args.append('-DWITH_CUDA=ON')
+                cuda_arch_list = spec.variants['cuda_arch'].value
+                cuda_arch = cuda_arch_list[0]
                 if cuda_arch != 'none':
-                    options.append('-DCUDA_FLAGS=-arch=sm_{0}'.format(cuda_arch[0]))
+                    args.append('-DCUDA_FLAGS=-arch=sm_{0}'.format(cuda_arch))
             else:
-                options.append('-DWITH_CUDA=OFF')
+                # Ensure build with cuda is disabled
+                args.append('-DWITH_CUDA=OFF')
+            ...
+            return args
+
+assuming only the ``WITH_CUDA`` and ``CUDA_FLAGS`` flags are required.
+You will need to customize options as needed for your build.
+
+This example also illustrates how to check for the ``cuda`` variant using
+``self.spec`` and how to retrieve the ``cuda_arch`` variant's value, which
+is a list, using ``self.spec.variants['cuda_arch'].value``.
+
+With over 70 packages using ``CudaPackage`` as of January 2021 there are
+lots of examples to choose from to get more ideas for using this package.

+oneAPI packages in Spack
+========================
+
+Spack can install and use the Intel oneAPI products. You may either
+use spack to install the oneAPI tools or use the `Intel
+installers`_. After installation, you may use the tools directly, or
+use Spack to build packages with the tools.
+
+The Spack Python class ``IntelOneapiPackage`` is a base class that is
+used by ``IntelOneapiCompilers``, ``IntelOneapiMkl``,
+``IntelOneapiTbb`` and other classes to implement the oneAPI
+packages. See the :ref:<package-list> for the full list of available
+oneAPI packages or use::
+
+  spack list -d oneAPI
+
+For more information on a specific package, do::
+
+  spack info <package-name>
+
+Intel no longer releases new versions of Parallel Studio, which can be
+used in Spack via the :ref:<intelpackage>. All of its components can
+now be found in oneAPI. 
+
+Examples
+========
+
+Building a Package With icx
+---------------------------
+
+In this example, we build patchelf with ``icc`` and ``icx``. The
+compilers are installed with spack.
+
+Install the oneAPI compilers::
+
+  spack install intel-oneapi-compilers
+
+Add the compilers to your ``compilers.yaml`` so spack can use them::
+
+  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/linux/bin/intel64
+  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/linux/bin
+
+Verify that the compilers are available::
+
+  spack compiler list
+
+The ``intel-oneapi-compilers`` package includes 2 families of
+compilers:
+
+* ``intel``: ``icc``, ``icpc``, ``ifort``. Intel's *classic*
+  compilers.
+* ``oneapi``: ``icx``, ``icpx``, ``ifx``. Intel's new generation of
+  compilers based on LLVM.
+
+To build the ``patchelf`` Spack package with ``icc``, do::
+
+  spack install patchelf%intel
+
+To build with with ``icx``, do ::
+
+  spack install patchelf%oneapi
+
+Using oneAPI MPI to Satisfy a Virtual Dependence
+------------------------------------------------------
+
+The ``hdf5`` package works with any compatible MPI implementation. To
+build ``hdf5`` with Intel oneAPI MPI do::
+
+  spack install hdf5 +mpi ^intel-oneapi-mpi
+
+Using an Externally Installed oneAPI
+====================================
+
+Spack can also use oneAPI tools that are manually installed with
+`Intel Installers`_.  The procedures for configuring Spack to use
+external compilers and libraries are different.
+
+Compilers
+---------
+
+To use the compilers, add some information about the installation to
+``compilers.yaml``. For most users, it is sufficient to do::
+
+  spack compiler add /opt/intel/oneapi/compiler/latest/linux/bin/intel64
+  spack compiler add /opt/intel/oneapi/compiler/latest/linux/bin
+
+Adapt the paths above if you did not install the tools in the default
+location. After adding the compilers, using them is the same
+as if you had installed the ``intel-oneapi-compilers`` package.
+Another option is to manually add the configuration to
+``compilers.yaml`` as described in :ref:`Compiler configuration
+<compiler-config>`.
+
+Libraries
+---------
+
+If you want Spack to use MKL that you have installed without Spack in
+the default location, then add the following to
+``~/.spack/packages.yaml``, adjusting the version as appropriate::
+
+  intel-oneapi-mkl:
+    externals:
+    - spec: intel-oneapi-mkl@2021.1.1
+      prefix: /opt/intel/oneapi/
+
+
+Using oneAPI Tools Installed by Spack
+=====================================
+
+Spack can be a convenient way to install and configure compilers and
+libaries, even if you do not intend to build a Spack package. If you
+want to build a Makefile project using Spack-installed oneAPI compilers,
+then use spack to configure your environment::
+
+  spack load intel-oneapi-compilers
+
+And then you can build with::
+
+  CXX=icpx make
+
+You can also use Spack-installed libraries. For example::
+
+  spack load intel-oneapi-mkl
+
+Will update your environment CPATH, LIBRARY_PATH, and other
+environment variables for building an application with MKL.
+
+More information
+================
+
+This section describes basic use of oneAPI, especially if it has
+changed compared to Parallel Studio. See :ref:<intelpackage> for more
+information on :ref:<intel-virtual-packages>,

-      step. The contents under ``paths:`` do not matter yet.
-
-   You are right to ask: "Why on earth is that necessary?" [fn8]_.
-   The answer lies in Spack striving for strict compiler consistency.
-   Consider what happens without such a pre-declared compiler stub:
-   Say, you ask Spack to install a particular version
-   ``intel-parallel-studio@edition.V``.  Spack will apply an unrelated compiler
-   spec to concretize and install your request, resulting in
-   ``intel-parallel-studio@edition.V %X``. That compiler ``%X`` is not going to
-   be the version that this new package itself provides. Rather, it would
-   typically be ``%gcc@...`` in a default Spack installation or possibly indeed
-   ``%intel@...``, but at a version that precedes ``V``.
-
-   The problem comes to the fore as soon as you try to use any virtual ``mkl``
-   or ``mpi`` packages that you would expect to now be provided by
-   ``intel-parallel-studio@edition.V``.  Spack will indeed see those virtual
-   packages, but only as being tied to the compiler that the package
-   ``intel-parallel-studio@edition.V`` was concretized with *at installation*.
-   If you were to install a client package with the new compilers now available
-   to you, you would naturally run ``spack install foo +mkl %intel@V``, yet
-   Spack will either complain about ``mkl%intel@V`` being missing (because it
-   only knows about ``mkl%X``) or it will go and attempt to install *another
-   instance* of ``intel-parallel-studio@edition.V %intel@V`` so as to match the
-   compiler spec ``%intel@V`` that you gave for your client package ``foo``.
-   This will be unexpected and will quickly get annoying because each
-   reinstallation takes up time and extra disk space.
-
-   To escape this trap, put the compiler stub declaration shown here in place,
-   then use that pre-declared compiler spec to install the actual package, as
-   shown next.  This approach works because during installation only the
-   package's own self-sufficient installer will be used, not any compiler.
+      step. The exact contents under ``paths:`` do not matter yet, but the paths must exist.
+
+   This temporary stub is required such that the ``intel-parallel-studio`` package
+   can be installed for the ``intel`` compiler (which the package itself is going
+   to provide after the installation) rather than an arbitrary system compiler.
+   The paths given in ``cc``, ``cxx``, ``f77``, ``fc`` must exist, but will
+   never be used to build anything during the installation of ``intel-parallel-studio``.
+
+   The reason for this stub is that ``intel-parallel-studio`` also provides the
+   ``mpi`` and ``mkl`` packages and when concretizing a spec, Spack ensures
+   strong consistency of the used compiler across all dependencies:  [fn8]_.
+   Installing a package ``foo +mkl %intel`` will make Spack look for a package
+   ``mkl %intel``, which can be provided by ``intel-parallel-studio+mkl %intel``,
+   but not by ``intel-parallel-studio+mkl %gcc``.
+
+   Failure to do so may result in additional installations of ``mkl``, ``intel-mpi`` or
+   even ``intel-parallel-studio`` as dependencies for other packages.

+-----------
+ROCmPackage
+-----------
+
+The ``ROCmPackage`` is not a build system but a helper package. Like ``CudaPackage``,
+it provides standard variants, dependencies, and conflicts to facilitate building
+packages using GPUs though for AMD in this case.
+
+You can find the source for this package (and suggestions for setting up your
+``compilers.yaml`` and ``packages.yaml`` files) at
+`<https://github.com/spack/spack/blob/develop/lib/spack/spack/build_systems/rocm.py>`__.
+
+^^^^^^^^
+Variants
+^^^^^^^^
+
+This package provides the following variants:
+
+* **rocm**
+
+  This variant is used to enable/disable building with ``rocm``.  
+  The default is disabled (or ``False``).
+
+* **amdgpu_target**
+
+  This variant supports the optional specification of the AMD GPU architecture.
+  Valid values are the names of the GPUs (e.g., ``gfx701``), which are maintained
+  in the ``amdgpu_targets`` property.
+
+^^^^^^^^^^^^
+Dependencies
+^^^^^^^^^^^^
+
+This package defines basic ``rocm`` dependencies, including ``llvm`` and ``hip``.
+
+^^^^^^^^^
+Conflicts
+^^^^^^^^^
+
+Conflicts are used to prevent builds with known bugs or issues. This package
+already requires that the ``amdgpu_target`` always be specified for ``rocm``
+builds. It also defines a conflict that prevents builds with an ``amdgpu_target``
+when ``rocm`` is disabled.
+
+Refer to `Conflicts <https://spack.readthedocs.io/en/latest/packaging_guide.html?highlight=conflicts#conflicts>`__
+for more information on package conflicts.
+
+^^^^^^^
+Methods
+^^^^^^^
+
+This package provides one custom helper method, which is used to build
+standard AMD hip compiler flags.
+
+**hip_flags**
+
+    This built-in static method returns the appropriately formatted
+    ``--amdgpu-target`` build option for ``hipcc``.
+
+    This method must be explicitly called when you are creating the
+    arguments for your build in order to use the values.
+
+^^^^^
+Usage
+^^^^^
+
+This helper package can be added to your package by adding it as a base
+class of your package.  For example, you can add it to your
+:ref:`CMakePackage <cmakepackage>`-based package as follows:
+
+.. code-block:: python
+   :emphasize-lines: 1,3-7,14-25
+
+    class MyRocmPackage(CMakePackage, ROCmPackage):
+        ...
+        # Ensure +rocm and amdgpu_targets are passed to dependencies
+        depends_on('mydeppackage', when='+rocm')
+        for val in ROCmPackage.amdgpu_targets:
+            depends_on('mydeppackage amdgpu_target={0}'.format(val),
+                       when='amdgpu_target={0}'.format(val))
+        ...
+
+        def cmake_args(self):
+            spec = self.spec
+            args = []
+            ...
+            if '+rocm' in spec:
+                # Set up the hip macros needed by the build
+                args.extend([
+                    '-DENABLE_HIP=ON',
+                    '-DHIP_ROOT_DIR={0}'.format(spec['hip'].prefix])
+                rocm_archs = spec.variants['amdgpu_target'].value
+                if 'none' not in rocm_archs:
+                    args.append('-DHIP_HIPCC_FLAGS=--amdgpu-target={0}'
+                                .format(",".join(rocm_archs)))
+            else:
+                # Ensure build with hip is disabled
+                args.append('-DENABLE_HIP=OFF')
+            ...
+            return args
+        ...
+
+assuming only on the ``ENABLE_HIP``, ``HIP_ROOT_DIR``, and ``HIP_HIPCC_FLAGS``
+macros are required to be set and the only dependency needing rocm options
+is ``mydeppackage``. You will need to customize the flags as needed for your
+build.
+
+This example also illustrates how to check for the ``rocm`` variant using
+``self.spec`` and how to retrieve the ``amdgpu_target`` variant's value
+using ``self.spec.variants['amdgpu_target'].value``.
+
+All five packages using ``ROCmPackage`` as of January 2021 also use the
+:ref:`CudaPackage <cudapackage>`. So it is worth looking at those packages
+to get ideas for creating a package that can support both ``cuda`` and
+``rocm``.

 no longer be able to fetch that version as soon as a new release comes
 out. To get around this, add the archive directory as a ``list_url``.
 
+^^^^^^^^^^^^^^^^^^^^^
+Bioconductor packages
+^^^^^^^^^^^^^^^^^^^^^
+
+Bioconductor packages are set up in a similar way to CRAN packages, but there
+are some very important distinctions. Bioconductor packages can be found at:
+https://bioconductor.org/. Bioconductor packages are R packages and so follow
+the same packaging scheme as CRAN packages. What is different is that
+Bioconductor itself is versioned and released. This scheme, using the
+Bioconductor package installer, allows further specification of the minimum
+version of R as well as further restrictions on the dependencies between
+packages than what is possible with the native R packaging system. Spack can
+not replicate these extra features and thus Bioconductor packages in Spack need
+to be managed as a group during updates in order to maintain package
+consistency with Bioconductor itself.
+
+Another key difference is that, while previous versions of packages are
+available, they are not available from a site that can be programmatically set,
+thus a ``list_url`` attribute can not be used. However, each package is also
+available in a git repository, with branches corresponding to each Bioconductor
+release. Thus, it is always possible to retrieve the version of any package
+corresponding to a Bioconductor release simply by fetching the branch that
+corresponds to the Bioconductor release of the package repository. For this
+reason, spack Bioconductor R packages use the git repository, with the commit
+of the respective branch used in the ``version()`` attribute of the package.
+
+^^^^^^^^^^^^^^^^^^^^^^^^
+cran and bioc attributes
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Much like the ``pypi`` attribute for python packages, due to the fact that R
+packages are obtained from specific repositories, it is possible to set up shortcut
+attributes that can be used to set ``homepage``, ``url``, ``list_url``, and
+``git``. For example, the following ``cran`` attribute:
+
+.. code-block:: python
+
+   cran = 'caret'
+
+is equivalent to:
+
+.. code-block:: python
+
+   homepage = 'https://cloud.r-project.org/package=caret'

+   list_url = 'https://cloud.r-project.org/src/contrib/Archive/caret'
+
+Likewise, the following ``bioc`` attribute:
+
+.. code-block:: python
+
+   bioc = 'BiocVersion'
+
+is equivalent to:

+-----------------
+Writing analyzers
+-----------------
+
+To write an analyzer, you should add a new python file to the
+analyzers module directory at ``lib/spack/spack/analyzers`` .
+Your analyzer should be a subclass of the :class:`AnalyzerBase <spack.analyzers.analyzer_base.AnalyzerBase>`. For example, if you want
+to add an analyzer class ``Myanalyzer`` you woul write to 
+``spack/analyzers/myanalyzer.py`` and import and 
+use the base as follows:
+
+.. code-block:: python
+
+    from .analyzer_base import AnalyzerBase
+
+    class Myanalyzer(AnalyzerBase):
+
+
+Note that the class name is your module file name, all lowercase
+except for the first capital letter. You can  look at other analyzers in 
+that analyzer directory for examples. The guide here will tell you about the basic functions needed.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^
+Analyzer Output Directory
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, when you run ``spack analyze run`` an analyzer output directory will
+be created in your spack user directory in your ``$HOME``. The reason we output here
+is because the install directory might not always be writable. 
+
+.. code-block:: console
+
+    ~/.spack/
+      analyzers
+      
+Result files will be written here, organized in subfolders in the same structure
+as the package, with each analyzer owning it's own subfolder. for example:
+
+
+.. code-block:: console
+
+    $ tree ~/.spack/analyzers/
+    /home/spackuser/.spack/analyzers/
+    └── linux-ubuntu20.04-skylake
+        └── gcc-9.3.0
+            └── zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2
+                ├── environment_variables
+                │   └── spack-analyzer-environment-variables.json
+                ├── install_files
+                │   └── spack-analyzer-install-files.json
+                └── libabigail
+                    └── lib
+                        └── spack-analyzer-libabigail-libz.so.1.2.11.xml 
+
+
+Notice that for the libabigail analyzer, since results are generated per object,
+we honor the object's folder in case there are equivalently named files in 
+different folders. The result files are typically written as json so they can be easily read and  uploaded in a future interaction with a monitor.
+
+
+^^^^^^^^^^^^^^^^^
+Analyzer Metadata
+^^^^^^^^^^^^^^^^^
+
+Your analyzer is required to have the class attributes ``name``, ``outfile``,
+and ``description``. These are printed to the user with they use the subcommand
+``spack analyze list-analyzers``.  Here is an example.
+As we mentioned above, note that this analyzer would live in a module named
+``libabigail.py`` in the analyzers folder so that the class can be discovered.
+
+
+.. code-block:: python
+
+    class Libabigail(AnalyzerBase):
+
+        name = "libabigail"
+        outfile = "spack-analyzer-libabigail.json"
+        description = "Application Binary Interface (ABI) features for objects"
+
+
+This means that the name and output file should be unique for your analyzer.
+Note that "all" cannot be the name of an analyzer, as this key is used to indicate
+that the user wants to run all analyzers.
+
+.. _analyzer_run_function:
+
+
+^^^^^^^^^^^^^^^^^^^^^^^^
+An analyzer run Function
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The core of an analyzer is its ``run()`` function, which should accept no
+arguments. You can assume your analyzer has the package spec of interest at ``self.spec``
+and it's up to the run function to generate whatever analysis data you need,
+and then return the object with a key as the analyzer name. The result data
+should be a list of objects, each with a name, ``analyzer_name``, ``install_file``,
+and one of ``value`` or ``binary_value``. The install file should be for a relative
+path, and not the absolute path. For example, let's say we extract a metric called
+``metric`` for ``bin/wget`` using our analyzer ``thebest-analyzer``. 
+We might have data that looks like this:
+
+.. code-block:: python
+
+    result = {"name": "metric", "analyzer_name": "thebest-analyzer", "value": "1", "install_file": "bin/wget"}
+
+
+We'd then return it as follows - note that they key is the analyzer name at ``self.name``.
+
+.. code-block:: python
+
+    return {self.name: result}
+
+This will save the complete result to the analyzer metadata folder, as described
+previously. If you want support for adding a different kind of metadata (e.g.,
+not associated with an install file) then the monitor server would need to be updated
+to support this first.
+
+
+^^^^^^^^^^^^^^^^^^^^^^^^^
+An analyzer init Function
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you don't need any extra dependencies or checks, you can skip defining an analyzer
+init function, as the base class will handle it. Typically, it will accept
+a spec, and an optional output directory (if the user does not want the default
+metadata folder for analyzer results). The analyzer init function should call
+it's parent init, and then do any extra checks or validation that are required to
+work. For example:
+
+.. code-block:: python
+
+    def __init__(self, spec, dirname=None):
+        super(Myanalyzer, self).__init__(spec, dirname)
+
+        # install extra dependencies, do extra preparation and checks here
+
+
+At the end of the init, you will have available to you:
+
+ - **self.spec**: the spec object
+ - **self.dirname**: an optional directory name the user as provided at init to save
+ - **self.output_dir**: the analyzer metadata directory, where we save by default
+ - **self.meta_dir**: the path to the package metadata directory (.spack) if you need it
+
+And can proceed to write your analyzer.
+
+
+^^^^^^^^^^^^^^^^^^^^^^^
+Saving Analyzer Results
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The analyzer will have ``save_result`` called, with the result object generated
+to save it to the filesystem, and if the user has added the ``--monitor`` flag
+to upload it to a monitor server. If your result follows an accepted result
+format and you don't need to parse it further, you don't need to add this 
+function to your class. However, if your result data is large or otherwise
+needs additional parsing, you can define it. If you define the function, it
+is useful to know about the ``output_dir`` property, which you can join
+with your output file relative path of choice:
+
+.. code-block:: python
+
+    outfile = os.path.join(self.output_dir, "my-output-file.txt")
+
+
+The directory will be provided by the ``output_dir`` property but it won't exist,
+so you should create it:
+
+
+.. code::block:: python
+
+    # Create the output directory
+    if not os.path.exists(self._output_dir):
+        os.makedirs(self._output_dir)
+
+
+If you are generating results that match to specific files in the package
+install directory, you should try to maintain those paths in the case that
+there are equivalently named files in different directories that would
+overwrite one another. As an example of an analyzer with a custom save,
+the Libabigail analyzer saves ``*.xml`` files to the analyzer metadata
+folder in ``run()``, as they are either binaries, or as xml (text) would
+usually be too big to pass in one request. For this reason, the files
+are saved during ``run()`` and the filenames added to the result object,
+and then when the result object is passed back into ``save_result()``,
+we skip saving to the filesystem, and instead read the file and send
+each one (separately) to the monitor:
+
+
+.. code-block:: python
+
+    def save_result(self, result, monitor=None, overwrite=False):
+        """ABI results are saved to individual files, so each one needs to be
+        read and uploaded. Result here should be the lookup generated in run(),
+        the key is the analyzer name, and each value is the result file.
+        We currently upload the entire xml as text because libabigail can't
+        easily read gzipped xml, but this will be updated when it can.
+        """
+        if not monitor:
+            return
+
+        name = self.spec.package.name
+
+        for obj, filename in result.get(self.name, {}).items():
+
+            # Don't include the prefix
+            rel_path = obj.replace(self.spec.prefix + os.path.sep, "")
+
+            # We've already saved the results to file during run
+            content = spack.monitor.read_file(filename)
+
+            # A result needs an analyzer, value or binary_value, and name
+            data = {"value": content, "install_file": rel_path, "name": "abidw-xml"}
+            tty.info("Sending result for %s %s to monitor." % (name, rel_path))
+            monitor.send_analyze_metadata(self.spec.package, {"libabigail": [data]})
+
+
+
+Notice that this function, if you define it, requires a result object (generated by
+``run()``, a monitor (if you want to send), and a boolean ``overwrite`` to be used
+to check if a result exists first, and not write to it if the result exists and 
+overwrite is False. Also notice that since we already saved these files to the analyzer metadata folder, we return early if a monitor isn't defined, because this function serves to send  results to the monitor. If you haven't saved anything to the analyzer metadata folder
+yet, you might want to do that here. You should also use ``tty.info`` to give
+the user a message of "Writing result to $DIRNAME."

+Writing Hooks
+-------------
+
+A hook is a callback that makes it easy to design functions that run
+for different events. We do this by way of defining hook types, and then
+inserting them at different places in the spack code base. Whenever a hook
+type triggers by way of a function call, we find all the hooks of that type,
+and run them.
+
+Spack defines hooks by way of a module at ``lib/spack/spack/hooks`` where we can define
+types of hooks in the ``__init__.py``, and then python files in that folder
+can use hook functions. The files are automatically parsed, so if you write
+a new file for some integration (e.g., ``lib/spack/spack/hooks/myintegration.py``
+you can then write hook functions in that file that will be automatically detected,
+and run whenever your hook is called. This section will cover the basic kind 
+of hooks, and how to write them.
+
+^^^^^^^^^^^^^^
+Types of Hooks
+^^^^^^^^^^^^^^
+
+The following hooks are currently implemented to make it easy for you,
+the developer, to add hooks at different stages of a spack install or similar. 
+If there is a hook that you would like and is missing, you can propose to add a new one.
+
+"""""""""""""""""""""
+``pre_install(spec)``
+"""""""""""""""""""""
+
+A ``pre_install`` hook is run within an install subprocess, directly before
+the install starts. It expects a single argument of a spec, and is run in 
+a multiprocessing subprocess. Note that if you see ``pre_install`` functions associated with packages these are not hooks
+as we have defined them here, but rather callback functions associated with 
+a package install.
+
+
+""""""""""""""""""""""
+``post_install(spec)``
+""""""""""""""""""""""
+
+A ``post_install`` hook is run within an install subprocess, directly after
+the install finishes, but before the build stage is removed. If you
+write one of these hooks, you should expect it to accept a spec as the only
+argument. This is run in a multiprocessing subprocess. This ``post_install`` is
+also seen in packages, but in this context not related to the hooks described
+here.
+
+
+""""""""""""""""""""""""""
+``on_install_start(spec)``
+""""""""""""""""""""""""""
+
+This hook is run at the beginning of ``lib/spack/spack/installer.py``,
+in the install function of a ``PackageInstaller``,
+and importantly is not part of a build process, but before it. This is when
+we have just newly grabbed the task, and are preparing to install. If you 
+write a hook of this type, you should provide the spec to it.
+
+.. code-block:: python
+
+    def on_install_start(spec):
+        """On start of an install, we want to...
+        """
+        print('on_install_start')
+    
+
+""""""""""""""""""""""""""""
+``on_install_success(spec)``
+""""""""""""""""""""""""""""
+
+This hook is run on a successful install, and is also run inside the build
+process, akin to ``post_install``. The main difference is that this hook
+is run outside of the context of the stage directory, meaning after the
+build stage has been removed and the user is alerted that the install was
+successful. If you need to write a hook that is run on success of a particular
+phase, you should use ``on_phase_success``.
+
+""""""""""""""""""""""""""""
+``on_install_failure(spec)``
+""""""""""""""""""""""""""""
+
+This hook is run given an install failure that happens outside of the build
+subprocess, but somewhere in ``installer.py`` when something else goes wrong.
+If you need to write a hook that is relevant to a failure within a build
+process, you would want to instead use ``on_phase_failure``.
+
+
+"""""""""""""""""""""""""""""""""""""""""""""""
+``on_phase_success(pkg, phase_name, log_file)``
+"""""""""""""""""""""""""""""""""""""""""""""""
+
+This hook is run within the install subprocess, and specifically when a phase
+successfully finishes. Since we are interested in the package, the name of
+the phase, and any output from it, we require:
+
+ - **pkg**: the package variable, which also has the attached spec at ``pkg.spec``
+ - **phase_name**: the name of the phase that was successful (e.g., configure)
+ - **log_file**: the path to the file with output, in case you need to inspect or otherwise interact with it.
+
+"""""""""""""""""""""""""""""""""""""""""""""
+``on_phase_error(pkg, phase_name, log_file)``
+"""""""""""""""""""""""""""""""""""""""""""""
+
+In the case of an error during a phase, we might want to trigger some event
+with a hook, and this is the purpose of this particular hook. Akin to
+``on_phase_success`` we require the same variables - the package that failed,
+the name of the phase, and the log file where we might find errors.
+
+"""""""""""""""""""""""""""""""""
+``on_analyzer_save(pkg, result)``
+"""""""""""""""""""""""""""""""""
+
+After an analyzer has saved some result for a package, this hook is called,
+and it provides the package that we just ran the analysis for, along with
+the loaded result. Typically, a result is structured to have the name
+of the analyzer as key, and the result object that is defined in detail in
+:ref:`analyzer_run_function`.
+
+.. code-block:: python
+
+    def on_analyzer_save(pkg, result):
+        """given a package and a result...
+        """
+        print('Do something extra with a package analysis result here')
+
+
+^^^^^^^^^^^^^^^^^^^^^^
+Adding a New Hook Type
+^^^^^^^^^^^^^^^^^^^^^^
+
+Adding a new hook type is very simple!  In ``lib/spack/spack/hooks/__init__.py``
+you can simply create a new ``HookRunner`` that is named to match your new hook.
+For example, let's say you want to add a new hook called ``post_log_write``
+to trigger after anything is written to a logger. You would add it as follows:
+
+.. code-block:: python
+
+    # pre/post install and run by the install subprocess
+    pre_install = HookRunner('pre_install')
+    post_install = HookRunner('post_install')
+
+    # hooks related to logging
+    post_log_write = HookRunner('post_log_write') # <- here is my new hook! 
+    
+
+You then need to decide what arguments my hook would expect. Since this is
+related to logging, let's say that you want a message and level. That means
+that when you add a python file to the ``lib/spack/spack/hooks``
+folder with one or more callbacks intended to be triggered by this hook. You might
+use my new hook as follows:
+
+.. code-block:: python
+
+    def post_log_write(message, level):
+        """Do something custom with the messsage and level every time we write
+        to the log
+        """
+        print('running post_log_write!')
+
+
+To use the hook, we would call it as follows somewhere in the logic to do logging.
+In this example, we use it outside of a logger that is already defined:
+
+.. code-block:: python
+
+    import spack.hooks
+
+    # We do something here to generate a logger and message
+    spack.hooks.post_log_write(message, logger.level)
+
+
+This is not to say that this would be the best way to implement an integration
+with the logger (you'd probably want to write a custom logger, or you could
+have the hook defined within the logger) but serves as an example of writing a hook.

+Monitoring
+==========
+
+You can use a `spack monitor <https://github.com/spack/spack-monitor>`_ "Spackmon"
+server to store a database of your packages, builds, and associated metadata 
+for provenance, research, or some other kind of development. You should
+follow the instructions in the `spack monitor documentation <https://spack-monitor.readthedocs.org>`_
+to first create a server along with a username and token for yourself.
+You can then use this guide to interact with the server.
+
+-------------------
+Analysis Monitoring
+-------------------
+
+To read about how to monitor an analysis (meaning you want to send analysis results
+to a server) see :ref:`analyze_monitoring`.
+
+---------------------
+Monitoring An Install
+---------------------
+
+Since an install is typically when you build packages, we logically want
+to tell spack to monitor during this step. Let's start with an example
+where we want to monitor the install of hdf5. Unless you have disabled authentication
+for the server, we first want to export our spack monitor token and username to the environment:
+
+.. code-block:: console
+ 
+    $ export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+    $ export SPACKMON_USER=spacky
+
+
+By default, the host for your server is expected to be at ``http://127.0.0.1``
+with a prefix of ``ms1``, and if this is the case, you can simply add the
+``--monitor`` flag to the install command:
+
+.. code-block:: console
+
+    $ spack install --monitor hdf5
+
+
+If you need to customize the host or the prefix, you can do that as well:
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-prefix monitor --monitor-host https://monitor-service.io hdf5
+
+
+As a precaution, we cut out early in the spack client if you have not provided
+authentication credentials. For example, if you run the command above without
+exporting your username or token, you'll see:
+
+.. code-block:: console
+
+    ==> Error: You are required to export SPACKMON_TOKEN and SPACKMON_USER
+
+This extra check is to ensure that we don't start any builds,
+and then discover that you forgot to export your token. However, if 
+your monitoring server has authentication disabled, you can tell this to
+the client to skip this step:
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-disable-auth hdf5
+
+If the service is not running, you'll cleanly exit early - the install will
+not continue if you've asked it to monitor and there is no service.
+For example, here is what you'll see if the monitoring service is not running:
+
+.. code-block:: console
+
+    [Errno 111] Connection refused
+
+
+If you want to continue builds (and stop monitoring) you can set the ``--monitor-keep-going``
+flag. 
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-keep-going hdf5
+
+This could mean that if a request fails, you only have partial or no data
+added to your monitoring database. This setting will not be applied to the
+first request to check if the server is running, but to subsequent requests.
+If you don't have a monitor server running and you want to build, simply
+don't provide the ``--monitor`` flag! Finally, if you want to provide one or
+more tags to your build, you can do:
+
+.. code-block:: console
+
+    # Add one tag, "pizza"
+    $ spack install --monitor --monitor-tags pizza hdf5
+
+    # Add two tags, "pizza" and "pasta"
+    $ spack install --monitor --monitor-tags pizza,pasta hdf5
+

+Deprecating old versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+There are many reasons to remove old versions of software:
+
+#. Security vulnerabilities (most serious reason)
+#. Changing build systems that increase package complexity
+#. Changing dependencies/patches/resources/flags that increase package complexity
+#. Maintainer/developer inability/unwillingness to support old versions
+#. No longer available for download (right to be forgotten)
+#. Package or version rename
+
+At the same time, there are many reasons to keep old versions of software:
+
+#. Reproducibility
+#. Requirements for older packages (e.g. some packages still rely on Qt 3)
+
+In general, you should not remove old versions from a ``package.py``. Instead,
+you should first deprecate them using the following syntax:
+
+.. code-block:: python
+
+   version('1.2.3', sha256='...', deprecated=True)
+
+
+This has two effects. First, ``spack info`` will no longer advertise that
+version. Second, commands like ``spack install`` that fetch the package will
+require user approval:
+
+.. code-block:: console
+
+   $ spack install openssl@1.0.1e
+   ==> Warning: openssl@1.0.1e is deprecated and may be removed in a future Spack release.
+   ==>   Fetch anyway? [y/N]
+
+
+If you use ``spack install --deprecated``, this check can be skipped.
+
+This also applies to package recipes that are renamed or removed. You should
+first deprecate all versions before removing a package. If you need to rename
+it, you can deprecate the old package and create a new package at the same
+time.
+
+Version deprecations should always last at least one Spack minor release cycle
+before the version is completely removed. For example, if a version is
+deprecated in Spack 0.16.0, it should not be removed until Spack 0.17.0. No
+version should be removed without such a deprecation process. This gives users
+a chance to complain about the deprecation in case the old version is needed
+for some application. If you require a deprecated version of a package, simply
+submit a PR to remove ``deprecated=True`` from the package. However, you may be
+asked to help maintain this version of the package if the current maintainers
+are unwilling to support this older version.

 Checking an installation
 ------------------------
 
-By default, Spack assumes that a build has failed if nothing is
-written to the install prefix, and that it has succeeded if anything
-(a file, a directory, etc.)  is written to the install prefix after
-``install()`` completes.
+A package that *appears* to install successfully does not mean
+it is actually installed correctly or will continue to work indefinitely.
+There are a number of possible points of failure so Spack provides
+features for checking the software along the way.
+
+Failures can occur during and after the installation process. The
+build may start but the software not end up fully installed. The
+installed software may not work at all or as expected. The software
+may work after being installed but, due to changes on the system,
+may stop working days, weeks, or months after being installed.
+
+This section describes Spack's support for checks that can be performed
+during and after its installation. The former checks are referred to as
+``build-time tests`` and the latter as ``stand-alone (or smoke) tests``.
+
+.. _build_time-tests:

+Build-time tests

+Spack infers the status of a build based on the contents of the install
+prefix. Success is assumed if anything (e.g., a file, directory) is

+to have failed. However, the presence of install prefix contents
+is not a sufficient indicator of success.

+Consider a simple autotools build using the following commands:

+Standard Autotools and CMake do not write anything to the prefix from
+the ``configure`` and ``make`` commands. Files are only written from
+the ``make install`` after the build completes.
+

+

+What can you do to check that the build is progressing satisfactorily?
+If there are specific files and or directories expected of a successful

+checks to be performed after one or more installation phases.
+
+.. _sanity-checks:

+Adding sanity checks
+""""""""""""""""""""
+
+Unfortunately, many builds of scientific software modify the installation
+prefix **before** ``make install``. Builds like this can falsely report
+success when an error occurs before the installation is complete. Simple
+sanity checks can be used to identify files and or directories that are
+required of a successful installation. Spack checks for the presence of
+the files and directories after ``install()`` runs. 
+
+If any of the listed files or directories are missing, then the build will
+fail and the install prefix will be removed. If they all exist, then Spack
+considers the build successful from a sanity check perspective and keeps
+the prefix in place.
+
+For example, the sanity checks for the ``reframe`` package below specify
+that eight paths must exist within the installation prefix after the
+``install`` method completes.
 
 .. code-block:: python
 
-   def install(self, spec, prefix):
-       configure("--prefix={0}".format(prefix))
-       make()
-       make("install")

-If you are using using standard autotools or CMake, ``configure`` and

+Adding installation phase tests
+"""""""""""""""""""""""""""""""
+
+Sometimes packages appear to build "correctly" only to have run-time
+behavior issues discovered at a later stage, such as after a full
+software stack relying on them has been built. Checks can be performed
+at different phases of the package installation to possibly avoid
+these types of problems. Some checks are built-in to different build
+systems, while others will need to be added to the package.
+
+Built-in installation phase tests are provided by packages inheriting
+from select :ref:`build systems <build-systems>`, where naming conventions
+are used to identify typical test identifiers for those systems. In
+general, you won't need to add anything to your package to take advantage
+of these tests if your software's build system complies with the convention;
+otherwise, you'll want or need to override the post-phase method to perform
+other checks.

+     - Not applicable
+     - ``test`` (module imports)
+
+For example, the ``Libelf`` package inherits from ``AutotoolsPackage``
+and its ``Makefile`` has a standard ``check`` target. So Spack will
+automatically run ``make check`` after the ``build`` phase when it
+is installed using the ``--test`` option, such as:
+
+.. code-block:: console
+
+   $ spack install --test=root libelf
+
+In addition to overriding any built-in build system installation
+phase tests, you can write your own install phase tests. You will
+need to use two decorators for each phase test method:
+
+* ``run_after``
+* ``on_package_attributes``
+
+The first decorator tells Spack when in the installation process to
+run your test method installation process; namely *after* the provided
+installation phase. The second decorator tells Spack to only run the
+checks when the ``--test`` option is provided on the command line. 
+
+.. note::
+
+   Be sure to place the directives above your test method in the order
+   ``run_after`` *then* ``on_package_attributes``.
+
+.. note::
+
+   You also want to be sure the package supports the phase you use
+   in the ``run_after`` directive. For example, ``PackageBase`` only
+   supports the ``install`` phase while the ``AutotoolsPackage`` and
+   ``MakefilePackage`` support both ``install`` and ``build`` phases.
+
+Assuming both ``build`` and ``install`` phases are available to you,
+you could add additional checks to be performed after each of those
+phases based on the skeleton provided below.
+
+.. code-block:: python
+
+   class YourMakefilePackage(MakefilePackage):
+       ...
+
+       @run_after('build')
+       @on_package_attributes(run_tests=True)
+       def check_build(self):
+            # Add your custom post-build phase tests
+            pass
+
+       @run_after('install')
+       @on_package_attributes(run_tests=True)
+       def check_install(self):
+            # Add your custom post-install phase tests
+            pass
+
+.. note::
+
+    You could also schedule work to be done **before** a given phase
+    using the ``run_before`` decorator.
+
+By way of a concrete example, the ``reframe`` package mentioned
+previously has a simple installation phase check that runs the
+installed executable. The check is implemented as follows:
+
+.. code-block:: python
+
+   class Reframe(Package):
+       ...
+
+       # check if we can run reframe
+       @run_after('install')
+       @on_package_attributes(run_tests=True)

+Stand-alone (or smoke) tests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+While build-time tests are integrated with the installation process,
+stand-alone tests are independent of that process.  Consequently, such
+tests can be performed days, even weeks, after the software is installed.
+
+Stand-alone tests are checks that should run relatively quickly -- as
+in on the order of at most a few minutes -- and ideally execute all
+aspects of the installed software, or at least key functionality. 
+
+.. note::
+
+    Execution speed is important because these tests are intended
+    to quickly assess whether the installed software works on the
+    system.
+    
+    Failing stand-alone tests indicate that there is no reason to
+    proceed with more resource-intensive tests.
+    
+    Passing stand-alone (or smoke) tests can lead to more thorough
+    testing, such as extensive unit or regression tests, or tests
+    that run at scale. Spack support for more thorough testing is
+    a work in progress.
+
+Stand-alone tests have their own test stage directory, which can be
+configured. These tests can compile or build software with the compiler
+used to build the package. They can use files cached from the build for
+testing the installation. Custom files, such as source, data, or expected
+outputs can be added for use in these tests.
+
+""""""""""""""""""""""""""""""""""""
+Configuring the test stage directory
+""""""""""""""""""""""""""""""""""""
+
+Stand-alone tests rely on a stage directory for building, running,
+and tracking results.
+The default directory, ``~/.spack/test``, is defined in
+:ref:`etc/spack/defaults/config.yaml <config-yaml>`.
+You can configure the location in the high-level ``config`` by adding
+or changing the ``test_stage`` path in the appropriate ``config.yaml``
+file such that:
+
+.. code-block:: yaml
+
+   config:
+     test_stage: /path/to/stage
+
+The package can access this path **during test processing** using
+`self.test_suite.stage`. 
+
+.. note::
+
+   The test stage path is established for the entire suite. That
+   means it is the root directory for all specs being installed
+   with the same `spack test run` command. Each spec gets its
+   own stage subdirectory.
+
+"""""""""""""""""""""""""
+Enabling test compilation
+"""""""""""""""""""""""""
+
+Some stand-alone tests will require access to the compiler with which
+the package was built, especially for library-only packages. You must
+enable loading the package's compiler configuration by setting the
+``test_requires_compiler`` property to ``True`` for your package.
+For example:
 
 .. code-block:: python
 
    class MyPackage(Package):
        ...
 
-       sanity_check_is_file = ['include/libelf.h']
-       sanity_check_is_dir  = [lib]
+       test_requires_compiler = True
 
-       def install(self, spec, prefix):
-           configure("--prefix=" + prefix)
-           make()
-           make("install")
+Setting this property to ``True`` makes the compiler available in the
+test environment through the canonical environment variables (e.g.,
+``CC``, ``CXX``, ``FC``, ``F77``).
 
-Now, after ``install()`` runs, Spack will check whether
-``$prefix/include/libelf.h`` exists and is a file, and whether
-``$prefix/lib`` exists and is a directory.  If the checks fail, then
-the build will fail and the install prefix will be removed.  If they

+Adding build-time files
+"""""""""""""""""""""""
+
+.. note::
 
-Sometimes packages finish to build "correctly" and issues with their run-time
-behavior are discovered only at a later stage, maybe after a full software stack
-relying on them has already been built. To avoid situations of that kind it's possible
-to write build-time tests that will be executed only if the option ``--run-tests``
-of ``spack install`` has been activated.
+    We highly recommend re-using build-time tests and input files
+    for testing installed software. These files are easier to keep
+    synchronized since they reside within the software's repository
+    than maintaining custom install test files with the Spack package.
 
-The proper way to write these tests is relying on two decorators that come with
-any base class listed in :ref:`installation_procedure`.
+You can use the ``cache_extra_test_sources`` method to copy directories
+and or files from the build stage directory to the package's installation
+directory.
+
+The signature for ``cache_extra_test_sources`` is:
 
 .. code-block:: python
 
-   @run_after('build')
-   @on_package_attributes(run_tests=True)
-   def check_build(self):
-        # Custom implementation goes here
-        pass
+   def cache_extra_test_sources(self, srcs):
+
+where ``srcs`` is a string or a list of strings corresponding to
+the paths for the files and or subdirectories, relative to the staged
+source, that are to be copied to the corresponding path relative to
+``self.install_test_root``. All of the contents within each subdirectory
+will be also be copied.
 
-The first decorator ``run_after('build')`` schedules this
-function to be invoked after the ``build`` phase has been executed, while the
-second one makes the invocation  conditional on the fact that ``self.run_tests == True``.
-It is also possible to schedule a function to be invoked *before* a given phase
-using the ``run_before`` decorator.
+For example, a package method for copying everything in the ``tests``
+subdirectory plus the ``foo.c`` and ``bar.c`` files from ``examples``
+can be implemented as shown below.
 
 .. note::
 
-    Default implementations for build-time tests
+   The ``run_after`` directive ensures associated files are copied
+   **after** the package is installed by the build process.
 
-        Packages that are built using specific build systems may already have a
-        default implementation for build-time tests. For instance :py:class:`~.AutotoolsPackage`
-        based packages will try to invoke ``make test`` and ``make check`` if
-        Spack is asked to run tests.
-        More information on each class is available in the the :py:mod:`~.spack.build_systems`
-        documentation.

+                   join_path('examples', 'foo.c'), 
+                   join_path('examples', 'bar.c')]
+           self.cache_extra_test_sources(srcs)
 
-.. _file-manipulation:
+In this case, the method copies the associated files from the build
+stage **after** the software is installed to the package's metadata
+directory. The result is the following directory and files will be
+available for use in stand-alone tests:
 
-^^^^^^^^^^^^^
-Install Tests
-^^^^^^^^^^^^^
+* ``join_path(self.install_test_root, 'tests')`` along with its files and subdirectories
+* ``join_path(self.install_test_root, 'examples', 'foo.c')``
+* ``join_path(self.install_test_root, 'examples', 'bar.c')``
 
-.. warning::
+.. note::
 
-   The API for adding and running install tests is not yet considered
-   stable and may change drastically in future releases. Packages with
-   upstreamed tests will be refactored to match changes to the API.
+    While source and input files are generally recommended, binaries
+    **may** also be cached by the build process for install testing.
+    Only you, as the package writer or maintainer, know whether these
+    would be appropriate stand-alone tests.
+
+.. note::
+
+   You are free to use a method name that is more suitable for
+   your package.
+
+.. _cache_custom_files:
 
-While build-tests are integrated with the build system, install tests
-may be added to Spack packages to be run independently of the install
-method.
+"""""""""""""""""""
+Adding custom files
+"""""""""""""""""""
 
-Install tests may be added by defining a ``test`` method with the following signature:
+Some tests may require additional files not available from the build.
+Examples include:
+
+- test source files
+- test input files
+- test build scripts
+- expected test output
+
+These extra files should be added to the ``test`` subdirectory of the
+package in the Spack repository. Spack will automatically copy any files
+in that directory to the test staging directory during stand-alone testing.
+
+The ``test`` method can access those files from the
+``self.test_suite.current_test_data_dir`` directory.
+
+.. _expected_test_output_from_file:
+
+"""""""""""""""""""""""""""""""""""
+Reading expected output from a file
+"""""""""""""""""""""""""""""""""""
+
+The helper function ``get_escaped_text_output`` is available for packages
+to retrieve and properly format the text from a file that contains the
+output that is expected when an executable is run using ``self.run_test``.
+
+The signature for ``get_escaped_text_output`` is:
 
 .. code-block:: python
 
-   def test(self):
+   def get_escaped_text_output(filename):
 
-These tests will be run in an environment set up to provide access to
-this package and all of its dependencies, including ``test``-type
-dependencies. Inside the ``test`` method, standard python ``assert``
-statements and other error reporting mechanisms can be used. Spack
-will report any errors as a test failure.
+where ``filename`` is the path to the file containing the expected output.
 
-Inside the test method, individual tests can be run separately (and
-continue transparently after a test failure) using the ``run_test``
-method. The signature for the ``run_test`` method is:
+The ``filename`` for a :ref:`custom file <cache_custom_files>` can be 
+accessed and used as illustrated by a simplified version of an ``sqlite``
+package check:
 
 .. code-block:: python
 
-   def run_test(self, exe, options=[], expected=[], status=0, installed=False,
-                purpose='', skip_missing=False, work_dir=None):
-
-This method will operate in ``work_dir`` if one is specified. It will
-search for an executable in the ``PATH`` variable named ``exe``, and
-if ``installed=True`` it will fail if that executable does not come
-from the prefix of the package being tested. If the executable is not
-found, it will fail the test unless ``skip_missing`` is set to
-``True``. The executable will be run with the options specified, and
-the return code will be checked against the ``status`` argument, which
-can be an integer or list of integers. Spack will also check that
-every string in ``expected`` is a regex matching part of the output of
-the executable. The ``purpose`` argument is recorded in the test log
-for debugging purposes.
-
-""""""""""""""""""""""""""""""""""""""
-Install tests that require compilation
-""""""""""""""""""""""""""""""""""""""
-
-Some tests may require access to the compiler with which the package
-was built, especially to test library-only packages. To ensure the
-compiler is configured as part of the test environment, set the
-attribute ``tests_require_compiler = True`` on the package. The
-compiler will be available through the canonical environment variables
-(``CC``, ``CXX``, ``FC``, ``F77``) in the test environment.
-
-""""""""""""""""""""""""""""""""""""""""""""""""
-Install tests that require build-time components
-""""""""""""""""""""""""""""""""""""""""""""""""
-
-Some packages cannot be easily tested without components from the
-build-time test suite. For those packages, the
-``cache_extra_test_sources`` method can be used.
+   class Sqlite(AutotoolsPackage):
+       ...
+
+       def test(self):
+           test_data_dir = self.test_suite.current_test_data_dir
+           db_filename = test_data_dir.join('packages.db')
+           ..
+
+           expected = get_escaped_text_output(test_data_dir.join('dump.out'))
+           self.run_test('sqlite3',
+                         [db_filename, '.dump'],
+                         expected,
+                         installed=True,
+                         purpose='test: checking dump output',
+                         skip_missing=False)
+
+Expected outputs do not have to be stored with the Spack package.
+Maintaining them with the source is actually preferable.
+
+Suppose a package's source has ``examples/foo.c`` and ``examples/foo.out``
+files that are copied for stand-alone test purposes using
+:ref:`cache_extra_test_sources <cache_extra_test_sources>` and the
+`run_test` method builds the executable ``examples/foo``. The package
+can retrieve the expected output from ``examples/foo.out`` using:
 
 .. code-block:: python
 
-   @run_after('install')
-   def cache_test_sources(self):
-       srcs = ['./tests/foo.c', './tests/bar.c']
-       self.cache_extra_test_sources(srcs)
+   class MyFooPackage(Package):
+       ...
+
+       def test(self):

+           filename = join_path(self.install_test_root, 'examples', 'foo.out')
+           expected = get_escaped_text_output(filename)
+           ..
 
-This method will copy the listed methods into the metadata directory
-of the package at the end of the install phase of the build. They will
-be available to the test method in the directory
-``self._extra_tests_path``.
+Alternatively, suppose ``MyFooPackage`` installs tests in ``share/tests``
+and their outputs in ``share/tests/outputs``. The expected output for
+``foo``, assuming it is still called ``foo.out``, can be retrieved as
+follows:

-Install tests can be run using the ``spack test run`` command. The

-specs provided to it, or if no specs are provided it will test all
-specs in the active environment, or all specs installed in Spack if no
-environment is active. Test suites can be named using the ``--alias``

-Packages to install test can be queried using the ``spack test list``

-Test suites can be found using the ``spack test find`` command. It

+""""""""""""""""""""""""
+Adding stand-alone tests
+""""""""""""""""""""""""
 
-The test stage is the working directory for all install tests run with
-Spack. By default, Spack uses ``~/.spack/test`` as the test stage. The
-test stage can be set in the high-level config:
+Stand-alone tests are defined in the package's ``test`` method. The
+default ``test`` method is a no-op so you'll want to override it to
+implement the tests.
 
-.. code-block:: yaml
+.. note::
 
-   config:
-     test_stage: /path/to/stage
+   Any package method named ``test`` is automatically executed by
+   Spack when the ``spack test run`` command is performed.
+
+For example, the ``MyPackage`` package below provides a skeleton for
+the test method.
+
+.. code-block:: python
+
+   class MyPackage(Package):
+       ...
+
+       def test(self):
+           # TODO: Add quick checks of the installed software
+           pass
+
+Stand-alone tests run in an environment that provides access to the
+package and all of its dependencies, including ``test``-type
+dependencies.
+
+Standard python ``assert`` statements and other error reporting
+mechanisms can be used in the ``test`` method. Spack will report
+such errors as test failures.
+
+You can implement multiple tests (or test parts) within the ``test``
+method using the ``run_test`` method. Each invocation is run separately
+in a manner that allows testing to continue after failures.
+
+The signature for ``run_test`` is:
+
+.. code-block:: python
+
+   def run_test(self, exe, options=[], expected=[], status=0,
+                installed=False, purpose='', skip_missing=False,
+                work_dir=None):
+
+where each argument has the following meaning:
+
+* ``exe`` is the executable to run.
+
+  If a name, the ``exe`` is required to be found in one of the paths
+  in the ``PATH`` environment variable **unless** ``skip_missing`` is
+  ``True``. Alternatively, a relative (to ``work_dir``) or fully
+  qualified path for the executable can be provided in ``exe``.
+
+  The test will fail if the resulting path is not within the prefix
+  of the package being tested **unless** ``installed`` is ``False``.
+
+* ``options`` is a list of the command line options.
+
+  Options are a list of strings to be passed to the executable when
+  it runs.
+  
+  The default is ``[]``, which means no options are provided to the
+  executable.
+ 
+* ``expected`` is an optional list of expected output strings.
+
+  Spack requires every string in ``expected`` to be a regex matching
+  part of the output from the test run (e.g.,
+  ``expected=['completed successfully', 'converged in']``).  The
+  output can also include expected failure outputs (e.g.,
+  ``expected=['failed to converge']``).
+
+  The expected output can be :ref:`read from a file
+  <expected_test_output_from_file>`.
+  
+  The default is ``expected=[]``, so Spack will not check the output.
+ 
+* ``status`` is the optional expected return code(s).
+
+  A list of return codes corresponding to successful execution can
+  be provided (e.g., ``status=[0,3,7]``). Support for non-zero return
+  codes allows for basic **expected failure** tests as well as different
+  return codes across versions of the software.
+  
+  The default is ``status=[0]``, which corresponds to **successful**
+  execution in the sense that the executable does not exit with a
+  failure code or raise an exception.
+ 
+* ``installed`` is used to require ``exe`` to be within the package
+  prefix.
+  
+  If ``True``, then the path for ``exe`` is required to be within the
+  package prefix; otherwise, the path is not constrained.
+  
+  The default is ``False``, so the fully qualified path for ``exe``
+  does **not** need to be within the installation directory.
+ 
+* ``purpose`` is an optional heading describing the the test part.
+ 
+  Output from the test is written to a test log file so this argument
+  serves as a searchable heading in text logs to highlight the start
+  of the test part. Having a description can be helpful when debugging
+  failing tests.
+
+* ``skip_missing`` is used to determine if the test should be skipped.
+
+  If ``True``, then the test part should be skipped if the executable
+  is missing; otherwise, the executable must exist. This option can
+  be useful when test executables are removed or change as the software
+  evolves in subsequent versions.
+
+  The default is ``False``, which means the test executable must be
+  present for any installable version of the software.
+ 
+* ``work_dir`` is the path to the directory from which the executable
+  will run.
+  
+  The default of ``None`` corresponds to the current directory (``'.'``).
+
+You may need to access files from one or more locations when writing
+the tests. This can happen if the software's repository does not
+include test source files or includes files but no way to build the
+executables using the installed headers and libraries. In these
+cases, you may need to reference the files relative to one or more
+root directory and associated package property. These are given in
+the table below.

+
+Stand-alone tests defined in parent (.e.g., :ref:`build-systems`) and
+virtual (e.g., :ref:`virtual-dependencies`) packages are available to
+packages that inherit from or provide interfaces for those packages,
+respectively. The table below summarizes the tests that will be included

+These tests are very generic so it is important that package
+developers and maintainers provide additional stand-alone tests
+customized to the package.
+
+One example of a package that adds its own stand-alone (or smoke)
+tests is the `Openmpi package
+<https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/openmpi/package.py>`_.
+The preliminary set of tests for the package performed the
+following checks:
+
+- installed binaries with the ``--version`` option return the expected
+  version;
+- outputs from (selected) installed binaries match expectations;
+- ``make all`` succeeds when building examples that were copied from the
+  source directory during package installation; and
+- outputs from running the copied and built examples match expectations.

+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Note about rebuilding buildcache index
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, while a pipeline job may rebuild a package, create a buildcache
+entry, and push it to the mirror, it does not automatically re-generate the
+mirror's buildcache index afterward.  Because the index is not needed by the
+default rebuild jobs in the pipeline, not updating the index at the end of
+each job avoids possible race conditions between simultaneous jobs, and it
+avoids the computational expense of regenerating the index.  This potentially
+saves minutes per job, depending on the number of binary packages in the
+mirror.  As a result, the default is that the mirror's buildcache index may
+not correctly reflect the mirror's contents at the end of a pipeline.
+
+To make sure the buildcache index is up to date at the end of your pipeline,
+spack generates a job to update the buildcache index of the target mirror
+at the end of each pipeline by default.  You can disable this behavior by
+adding ``rebuild-index: False`` inside the ``gitlab-ci`` section of your
+spack environment.  Spack will assign the job any runner attributes found
+on the ``service-job-attributes``, if you have provided that in your
+``spack.yaml``.
+
+.. _noop_jobs:
+
+^^^^^^^^^^^^^^^^^^^^^^^
+Note about "no-op" jobs
+^^^^^^^^^^^^^^^^^^^^^^^
+
+If no specs in an environment need to be rebuilt during a given pipeline run
+(meaning all are already up to date on the mirror), a single succesful job
+(a NO-OP) is still generated to avoid an empty pipeline (which GitLab
+considers to be an error).  An optional ``service-job-attributes`` section
+can be added to your ``spack.yaml`` where you can provide ``tags`` and
+``image`` or ``variables`` for the generated NO-OP job.  This section also
+supports providing ``before_script``, ``script``, and ``after_script``, in
+case you want to take some custom actions in the case of any empty pipeline.
+
+Following is an example of this section added to a ``spack.yaml``:
+
+.. code-block:: yaml
+
+   spack:
+     specs:
+       - openmpi
+     mirrors:
+       cloud_gitlab: https://mirror.spack.io
+     gitlab-ci:
+       mappings:
+         - match:
+             - os=centos8
+           runner-attributes:
+             tags:
+               - custom
+               - tag
+             image: spack/centos7
+       service-job-attributes:
+         tags: ['custom', 'tag']
+         image:
+           name: 'some.image.registry/custom-image:latest'
+           entrypoint: ['/bin/bash']
+         script:
+           - echo "Custom message in a custom script"
+
+The example above illustrates how you can provide the attributes used to run
+the NO-OP job in the case of an empty pipeline.  The only field for the NO-OP
+job that might be generated for you is ``script``, but that will only happen
+if you do not provide one yourself.

+
+    Python would compare ``Widgets`` lexicographically based on their
+    tuples. The issue there for simple comparators is that we have to
+    bulid the tuples *and* we have to generate all the values in them up
+    front. When implementing comparisons for large data structures, this
+    can be costly.
+
+    Lazy lexicographic comparison maps the tuple comparison shown above
+    to generator functions. Instead of comparing based on pre-constructed
+    tuple keys, users of this decorator can compare using elements from a
+    generator. So, you'd write::
+
+        @lazy_lexicographic_ordering
+        class Widget:
+            def _cmp_iter(self):
+                yield a
+                yield b
+                def cd_fun():
+                    yield c
+                    yield d
+                yield cd_fun
+                yield e
+
+            # operators are added by decorator
+
+    There are no tuples preconstructed, and the generator does not have
+    to complete. Instead of tuples, we simply make functions that lazily
+    yield what would've been in the tuple. The
+    ``@lazy_lexicographic_ordering`` decorator handles the details of
+    implementing comparison operators, and the ``Widget`` implementor
+    only has to worry about writing ``_cmp_iter``, and making sure the
+    elements in it are also comparable.
+
+    Some things to note:
+
+      * If a class already has ``__eq__``, ``__ne__``, ``__lt__``,
+        ``__le__``, ``__gt__``, ``__ge__``, or ``__hash__`` defined, this
+        decorator will overwrite them.
+
+      * If ``set_hash`` is ``False``, this will not overwrite
+        ``__hash__``.
+
+      * This class uses Python 2 None-comparison semantics. If you yield
+        None and it is compared to a non-None type, None will always be
+        less than the other object.
+
+    Raises:
+        TypeError: If the class does not have a ``_cmp_iter`` method

     object-oriented computational framework that is designed with single
-    and multi-domain multi-physics applications in mind. AMP can be used
-    to build powerful and flexible multi-physics simulation algorithms
-    from lightweight operator, solver, linear algebra, material database,
-    discretization, and meshing components. The AMP design is meant to
-    enable existing investments in application codes to be leveraged without
-    having to adopt dramatically different data structures while developing
-    new computational science applications. Application components are
-    represented as discrete mathematical operators that only require a
-    minimal interface and through operator composition the incremental
-    development of complex parallel applications is enabled. AMP is meant
-    to allow application domain scientists, computer scientists and

+Subject: [PATCH] Add detection of arm64 architecture for macos builds
+
+This commit adds detection of arm64 for macos builds on arm64 hardware.
+The only change necessary is an additional case in the code where
+macos.inc queries and detects the system architecture.

+# Legion Spack Package Notes
+
+The Legion Spack package follows the underlying approach used in Legion's CMake-based build infrastructure.  If you are not familiar with using Spack, we encourage you to start with the **[Spack 101 Tutorial](https://spack-tutorial.readthedocs.io/en/latest/)**.  For more background on Legion please visit the project [website](https://legion.stanford.edu). There you can find information on getting started, tutorials, and supporting documentation.
+
+## Versions
+
+We strongly recommend the majority of users start with the latest **stable** branch of Legion.  This will guarantee the most regularly tested and debugged version of the code.  We also strive to have quarterly tagged release throughout the calendar year starting March (e.g., legion-YY.MM.0 where MM starts at *'03'* and runs through *'12'* for any calendar year).  These versioned downloads are captured via the [Legion GitHub page](https://github.com/StanfordLegion/legion) and captured in the Spack package for individual use via the naming convention above.  The details for each release are captured in the CHANGES.txt file at the top-level of the repository.
+
+## Spack Usage and Details
+
+**NOTE: This version of the Legion *spackage* no longer depends upon an external GASNet spackage.  Instead, as supported and preferred by the GASNet developers, Legion internalizes the GASNet configuration and build process tailored to Legion's needs.  At present this approach should minimize both building and configuration issues that have occurred in the past.**
+
+With a working installation of Spack following variants can be used to download, configure, and build legion.  As of its latest release Legion uses features from C++11 and can be build using either GCC or Clang (and likely any other compilers with full C++11 support).  For example,
+
+    spack install legion %clang@10.0
+
+will build and install Legion using version 10.0 of the clang compiler.  Additional compiler flags (beyond those automatically enabled by the underlying Legion CMake configuration) may be specified by using the `cppflags` option to Spack:
+
+    spack install legion %clang@10.0 cppflags=-Wall
+
+You can find more details about customizing the compiler with Spack [here](https://spack-tutorial.readthedocs.io/en/latest/tutorial_basics.html#customizing-compilers).
+
+There are a number of configuration parameters (variants) for Legion that can be specified on the command line.  To see a complete listing of these variants you can use the following command:
+
+    spack info legion
+
+The default build and install of Legion is suitable for laptop/desktop development needs.  Additional variants will need to be specified to build for distributed memory systems, GPU support, and other features (e.g., debugging, profiling, etc.).  A full list of the currently supported variants is provided below.
+
+These variants may then be used on the Spack command line to customize the build of Legion you would like to install.  For boolean-based variants the `+`, `-`, or `~` *sigils* can be used. In this case, the `+` specifies a `True` value and either `-` or `~` can be used for the `False` setting (two values for `False` are provided to avoid conflicts with shell command line parameters. For example,
+
+    spack install legion@stable~cuda+hdf5%clang10.0
+
+will build/install the stable version of Legion without CUDA and with HDF5 support; using Clang 10.0 as the compiler.  See below for more examples of the various package options. 
+
+## Overview of Legion's Spack Variants
+
+
+This section provides an overview of the variants that are available for builds and installations of Legion and the underlying Realm runtime libraries.  These variants range from important configuration parameters for many users, to more involved and low-level details more likely to be leveraged when debugging correctness and performance issues.  For these last set of use cases we encourage users to visit the Legion [Debugging](https://legion.stanford.edu/debugging/) and [Profiling](https://legion.stanford.edu/profiling/) pages.
+
+Note that any variants with a default of `on` or `off` are boolean values and may be configured on the Spack command line using the `+`, or `-` (or `~`) sigils.
+
+Finally, to build the highest performing installation of Legion requires an appropriate configuration and installation of GASNet-Ex (while we have support for an MPI transport layer it is still in testing and evaluation for achieving the best possible performance).  See the following section for details on the steps needed to build a high-performance install of Legion using Spack.
+
+### Debugging & Internal Runtime Configurations
+
+* **`build_type`**: This variant exposes the CMake build type setting.  Following directly from CMake these available values for this variant are [`Debug`, `RelWithDebInfo`, and `Release`]. `default=RelWithDebInfo`
+
+* **`bounds_checks`**:  This variant supports `on` or `off` values and enables, or disables bounds checking within the runtime's data accessors.  This is helpful for debugging but  does have the potential to degrade performance (therefore it is disabled in the default build).  `default=off`
+
+* **`privilege_checks`**: This variant enables the runtime checking of data privileges in Legion's data accessors. This can helpful in debugging applications. `default=off`
+
+* **`spy`**: This variant enables applications to produce detailed logging information for debugging with the [Legion Spy](https://legion.stanford.edu/debugging/#legion-spy) tool.  `default=off`
+
+* **`max_dims`**: This variant provides an integral value for the maximum number of dimensions in a logical region that are supported by the build/install.  `default=3`  *Note: Currently supported values range from 1 to 9.*
+
+* **`max_fields`**: This variant provides an integral value for the maximum number of fields that may be stored within a logical region.  `default=512` *Note: Internally this requires a value that is a power-of-two -- if a non power-of-two value is provided the next largest power-of-two will be used.*
+
+* **`output_level`**: This variant enables the (dynamic) debugging level for the runtime.  It can be one of the following values: [`spew`, `debug`, `info`, `print`, `warning`, `error`, `fatal`, or `none`].  `default=warning`
+
+* **`papi`**: This variant enables PAPI performance measurements.  `default=off`
+
+* **`redop_complex`** This variant enables support for the reduction of complex types. `default=off`  Note: will be enabled when `+bindings` is set.
+
+* **`shared_libs`**: Build shared libraries for Legion and Realm. `default=off`
+
+* **`enable_tls`**: This variant supports `on` or `off` and enables thread-local-storage of the Legion runtime context.  `default=off`
+
+### Bindings & Interoperability
+
+* **`bindings`**: This variant supports `on` or `off` and will build the language bindings for Legion.  In addition to the required C++ interface, this currently includes C, Python, and Fortran. `default=off`  Note you can use `+python` or `+fortran` to select a subset of these bindings.
+
+* **`python`**: This variant enables Python support in terms of both bindings and runtime support (where instance(s) of the Python interpreter must be available.) `default=off`
+
+* **`fortran`**: This variant supports `on` or `off` and enables building of Fortran language bindings for Legion. `default=off`
+
+[//]: <> (TOOD: More details here on Kokkos interop?)
+
+* **`kokkos`**: Enable support for interoperability with [Kokkos](https://github.com/kokkos) use in Legion tasks. `default=off`
+
+[//]: <> (TOOD: More details here on OpenMP interop?)
+
+* **`openmp`**: This variant enables OpenMP support within Legion tasks (and within the Realm runtime). Please note that the full OpenMP feature set (e.g. OpenMP 5.0) is not fully supported when enabling this feature.  `default=off`
+
+* **`libdl`**: Enable support for dynamic object loading (via "libdl").  `default=on`
+
+### Processor Architecture Support (e.g., GPUs)
+
+* **`cuda`**: This variant supports `on` or `off` and enables CUDA support within Legion.  `default=off`
+
+* **`cuda_arch`**: This variant specifics the specific CUDA architecture to support within the Legion build/installation.  Currently this variant must be one of [`60`, `70`, `75`, or `80`].  Where `60` is the Pascal architecture, `70` is for Volta, `75` is for Turing, and `80` is for `Volta`. `default=70`
+
+* **`cuda_hijack`**:  This variant supports `on` or `off` and determines if the build enables performance enhancements by "*hijacking* entry points into CUDA's runtime API; thus, it obviously implies `+cuda`.This is a performance enhancement and not necessary but suggested for production use cases on NVIDIA-based systems.  `default=off`
+
+### External Library Support
+
+* **`hdf5`**: This variant supports `on` or `off` and enables building of HDF5 support within the runtime. `default=off`
+
+* **`hwloc`**: Build using "libhwloc" support for numa-aware topology support within Realm (Legion's low-level runtime layer).  `default=off`
+
+* **`zlib`**: This variant enables support for zlib. `default=on`
+
+### Distributed Memory/Network Transport/Interconnect Support
+
+* **`network`**: This variant specifies what network transport layer Legion/Realm should use for moving data across the distributed memories of a system.  The options are currently: [`gasnet`, `mpi`, or `none`].  The most tested and reliable interface for distributed memory systems is `gasnet`.  Via this package GASNet will be automatically configured and built. If you want to use a pre-installed version of GASNet you can use the `gasnet_root` variant; this will disable the automatic/internal installation of GASNet. We strongly encourage the use of the automatic configuration and build mechanism as it is tailored to Legion's use cases. If you would like to read more about please visit their [web page](https://gasnet.lbl.gov).  Note that the `mpi` transport layer is new and still being tuned and debugged.  Finally, if you want to run on a single system (e.g., a desktop or laptop) for development activities you may drop this parameter or specify `network=none`.  `default=none`
+
+* **`conduit`** requires `(network=gasnet)` **only**: This variant selects the GASNet conduit to use and must be provided when `network=gasnet`.  The current choices are: [`aries`, `ibv`, `mpi`, `ucx`, `udp`, or `none`]:  defaults to `none`.
+  * **aries**: Aries for Cray XC series (see [documentation](https://gasnet.lbl.gov/dist-ex/aries-conduit/README)).
+  * **ibv**: OpenIB/OpenFabrics Verbs for InfiniBand (see [documentation](https://gasnet.lbl.gov/dist-ex/ibv-conduit/README)).
+  * **mpi**: Portable conduit, works on any network with MPI 1.1 or newer (see [documentation](https://gasnet.lbl.gov/dist-ex/mpi-conduit/README)).
+  * **ucx**: *(NOTE: EXPERIMENTAL)*  Unified Communication X framework (see [documentation](https://gasnet.lbl.gov/dist-ex/ucx-conduit/README)).
+  * **udp**: Portable conduit, works on any network with a TCP/IP stack (see [documentation](https://gasnet.lbl.gov/dist-ex/udp-conduit/README)).
+
+* **`gasnet_root`**: This variant points the package at a pre-installed version of GASNet for use when building Legion.  This skips the default behavior of embedding the GASNet build within that of Legion. It requires that `conduit` be set to match that used by the installed version of GASNet (*note that incorrectly setting `conduit` could result in failures that are not caught by the Spack package as failures will only occur during the build of Legion*). `default=/usr/local`
+
+## Examples
+
+This section highlights a few common configurations/installations for various common installations of Legion. 
+
+### Laptop/Desktop Development
+
+The default configuration will build a version of Legion without network support that is often helpful in laptop or desktop installs for development using Legion. The first example is the most straightforward and enables a CPU-only configuration of Legion:
+
+`$ spack install legion@stable`
+
+Given that many uses cases for laptop/desktop development involve debugging Legion you might want to consider enabling [Legion Spy](https://legion.stanford.edu/debugging/#legion-spy), bounds and privilege checks, and optionally enable debugging level output diagnostics:
+
+`$ spack install legion@stable +spy +bounds_checks +privilege_checks [output=debug]`
+
+Note that by specifying `+spy` the package will also install the Legion profiler.  Both will be available in the corresponding `bin` directory created by Spack's install mechanisms.
+
+#### Adding GPU Support
+
+To enable support for NVIDIA GPUs with Legion you can add the `+cuda` variant to the examples provided above.  In addition, you can also use the `cuda_arch` flag to enable specific GPU architectures.  For example, the follow command line installs the stable version of Legion with CUDA support for NVIDIA's Volta architecture:
+
+`$ spack install legion@stable +cuda cuda_arch=70`
+
+If you wanted to program tasks using Kokkos support for GPUs you can simply add the `+kokkos` option to the previous command line: 
+
+`$ spack install legion@stable +cuda cuda_arch=70 +kokkos`
+
+this will enable Kokkos interoperability in Legion and also build and configure a version of Kokkos with cuda and Volta GPU support.
+
+#### Networking/Distributed Memory Support 
+
+In order to add modify the above configuration to support a distributed memory architecture you need to add a `network` target.  For example, to build a version of Legion that uses GASNet for the data transport layer you would specify:
+
+`$ spack install legion@stable +cuda cuda_arch=70 +kokkos network=gasnet`
+
+Without the addition of a specific GASNet *conduit* this command will use the UDP conduit. To change this to support a Infniband-based cluster you would add:
+
+`$ spack install legion@stable +cuda cuda_arch=70 +kokkos network=gasnet conduit=ibv`
+
+For a pre-existing installation of GASNet you can point the package at the root directory of the installation (also often know as the installation *prefix*). For example, to point the package at a version installed under `/opt/local` (*i.e., the include files are stored under `/opt/local/include` and libraries are in `/opt/local/lib`*) you would add `gasnet_root=/opt/local` to the command line.

+From: sbolding <sbolding@lanl.gov>
+Date: Mon, 29 Mar 2021 19:13:28 -0600
+Subject: [PATCH] Apply patch for icpc
+
+icpc in some way utilizes the preprocessor of the associated "developer
+tools" used by the compiler. This leads to, in some cases, a
+preprocessor claiming support for `__tuple_element_packs`, even though
+icpc (as of version 21.1) can't actually parse such code.  Just use the
+MPARK_TUPLE_ELEMENT_PACK impl with __icc until icpc supports it.
+
+Fixes #77

+Process names have a maximum length of 16 bytes and the buffer used has a
+length of 16 bytes, but the compiler is picky about writing and arbirary
+string into that small buffer. Tell the compiler to write max. 15 chars +
+'\0', to make it happy.

+Subject: [PATCH 1/2] Fix import of symlinks outside of path
+
+Makes load_module_from_file able to import files within the path that
+are just a symlink to a file outside of the path.
+modutils is using realpath at the moment which will resolve the symlink
+and don't allow the import as the file is detected outside of the
+available paths. By checking both abspath and realpath this patches add
+support for such scenarios.

-    fast access functions."""
+    """Memory-Efficient Storage of Large Data on Disk and Fast Access Functions
+
+    The ff package provides data structures that are stored on disk but behave
+    (almost) as if they were in RAM by transparently  mapping only a section
+    (pagesize) in main memory - the effective  virtual memory consumption per
+    ff object. ff supports R's standard  atomic data types 'double', 'logical',
+    'raw' and 'integer' and  non-standard atomic types boolean (1 bit), quad (2
+    bit unsigned),  nibble (4 bit unsigned), byte (1 byte signed with NAs),
+    ubyte (1 byte  unsigned), short (2 byte signed with NAs), ushort (2 byte
+    unsigned),  single (4 byte float with NAs). For example 'quad' allows
+    efficient  storage of genomic data as an 'A','T','G','C' factor. The
+    unsigned  types support 'circular' arithmetic. There is also support for
+    close-to-atomic types 'factor', 'ordered', 'POSIXct', 'Date' and  custom
+    close-to-atomic types.  ff not only has native C-support for vectors,
+    matrices and arrays  with flexible dimorder (major column-order, major
+    row-order and  generalizations for arrays). There is also a ffdf class not
+    unlike  data.frames and import/export filters for csv files. ff objects
+    store raw data in binary flat files in native encoding, and complement this
+    with metadata stored in R as physical and virtual attributes. ff objects
+    have well-defined hybrid copying semantics,  which gives rise to certain
+    performance improvements through  virtualization. ff objects can be stored
+    and reopened across R  sessions. ff files can be shared by multiple ff R
+    objects  (using different data en/de-coding schemes) in the same process
+    or from multiple R processes to exploit parallelism. A wide choice of
+    finalizer options allows to work with 'permanent' files as well as
+    creating/removing 'temporary' ff files completely transparent to the  user.
+    On certain OS/Filesystem combinations, creating the ff files works without
+    notable delay thanks to using sparse file allocation. Several access
+    optimization techniques such as Hybrid Index  Preprocessing and
+    Virtualization are implemented to achieve good  performance even with large
+    datasets, for example virtual matrix  transpose without touching a single
+    byte on disk. Further, to reduce  disk I/O, 'logicals' and non-standard
+    data types get stored native and  compact on binary flat files i.e.
+    logicals take up exactly 2 bits to  represent TRUE, FALSE and NA.  Beyond
+    basic access functions, the ff package also provides  compatibility
+    functions that facilitate writing code for ff and ram  objects and support
+    for batch processing on ff objects (e.g. as.ram,  as.ff, ffapply). ff
+    interfaces closely with functionality from package  'bit': chunked looping,
+    fast bit operations and coercions between  different objects that can store
+    subscript information ('bit',  'bitwhich', ff 'boolean', ri range index, hi
+    hybrid index). This allows to work interactively with selections of large
+    datasets and quickly  modify selection criteria.  Further high-performance
+    enhancements can be made available upon request.x """

+    methods include: heteroscedasticity-consistent (HC) covariances for
+    cross-section data; heteroscedasticity- and autocorrelation-consistent
+    (HAC) covariances for time series data (such as Andrews' kernel HAC,
+    Newey-West, and WEAVE estimators); clustered covariances (one-way and
+    multi-way); panel and panel-corrected covariances;
+    outer-product-of-gradients covariances; and (clustered) bootstrap
+    covariances. All methods are applicable to (generalized) linear model
+    objects fitted by lm() and glm() but can also be adapted to other classes
+    through S3 methods. Details can be found in Zeileis et al. (2020)
+    <doi:10.18637/jss.v095.i01>, Zeileis (2004) <doi:10.18637/jss.v011.i10> and

+    An implementation of about 6 major classes of statistical regression
+    models. The central algorithm is Fisher scoring and iterative reweighted
+    least squares. At the heart of this package are the vector generalized
+    linear and additive model (VGLM/VGAM) classes. VGLMs can be loosely thought
+    of as multivariate GLMs. VGAMs are data-driven VGLMs that use smoothing.
+    The book "Vector Generalized Linear and Additive Models: With an

+    details of the statistical framework and the package. Currently only
+    fixed-effects models are implemented. Many (150+) models and distributions
+    are estimated by maximum likelihood estimation (MLE) or penalized MLE. The
+    other classes are RR-VGLMs (reduced-rank VGLMs), quadratic RR-VGLMs,
+    reduced-rank VGAMs, RCIMs (row-column interaction models)---these classes
+    perform constrained and unconstrained quadratic ordination (CQO/UQO) models
+    in ecology, as well as constrained additive ordination (CAO). Hauck-Donner

-+// A struct is defined in this header file called 'SIMDVec' which can be used
-+// by applications which attempt to access the contents of an _m128 struct
-+// directly.  It is important to note that accessing the __m128 struct directly
-+// is bad coding practice by Microsoft: @see:
-+// https://msdn.microsoft.com/en-us/library/ayeb3ayc.aspx
-+//
-+// However, some legacy source code may try to access the contents of an __m128
-+// struct directly so the developer can use the SIMDVec as an alias for it.  Any
-+// casting must be done manually by the developer, as you cannot cast or
-+// otherwise alias the base NEON data type for intrinsic operations.
-+//
-+// union intended to allow direct access to an __m128 variable using the names
-+// that the MSVC compiler provides.  This union should really only be used when
-+// trying to access the members of the vector as integer values.  GCC/clang
-+// allow native access to the float members through a simple array access
-+// operator (in C since 4.6, in C++ since 4.8).
-+//
-+// Ideally direct accesses to SIMD vectors should not be used since it can cause
-+// a performance hit.  If it really is needed however, the original __m128
-+// variable can be aliased with a pointer to this union and used to access
-+// individual components.  The use of this union should be hidden behind a macro
-+// that is used throughout the codebase to access the members instead of always
-+// declaring this type of variable.

+Date: Fri, 14 May 2021 15:30:09 -0400
+Subject: [PATCH] Include sys/sysmacros.h in testlib.h
+
+In recent Linux systems, major() and minor() are defined in
+sys/sysmacros.h and sys/types.h no longer includes sys/sysmacros.h.  So,
+we need to include sys/sysmacros.h in testlib.h.
+
+Also adds a check for the existence of sys/sysmacros.h in configure.ac.
+
+Include sys/sysmacros.h in testlib.h

+Subject: [PATCH] Make sure we don't leak our findmpi module
+
+Consumers of VTK-m shouldn't use VTK-m find mpi module unless
+they explicitly want to. This makes sure that by default only
+VTK-m uses it.
