+Spack on Cray
+-----------------------------
+
+Spack differs slightly when used on a Cray system. The architecture spec
+can differentiate between the front-end and back-end processor and operating system.
+For example, on Edison at NERSC, the back-end target processor
+is \"Ivy Bridge\", so you can specify to use the back-end this way:
+
+.. code-block:: sh
+
+ spack install zlib target=ivybridge
+
+You can also use the operating system to build against the back-end:
+
+.. code-block:: sh
+
+ spack install zlib os=CNL10
+
+Notice that the name includes both the operating system name and the major
+version number concatenated together.
+
+Alternatively, if you want to build something for the front-end,
+you can specify the front-end target processor. The processor for a login node
+on Edison is \"Sandy bridge\" so we specify on the command line like so:
+
+.. code-block:: sh
+

+
+Cray compiler detection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Spack can detect compilers using two methods. For the front-end, we treat
+everything the same. The difference lies in back-end compiler detection.
+Back-end compiler detection is made via the Tcl module avail command.
+Once it detects the compiler it writes the appropriate PrgEnv and compiler
+module name to compilers.yaml and sets the paths to each compiler with Cray\'s
+compiler wrapper names (i.e. cc, CC, ftn). During build time, Spack will load
+the correct PrgEnv and compiler module and will call appropriate wrapper.
+
+The compilers.yaml config file will also differ. There is a
+modules section that is filled with the compiler\'s Programming Environment
+and module name. On other systems, this field is empty []::
+
+ ...
+ - compiler:
+ modules:
+ - PrgEnv-intel
+ - intel/15.0.109
+ ...
+
+As mentioned earlier, the compiler paths will look different on a Cray system.
+Since most compilers are invoked using cc, CC and ftn, the paths for each
+compiler are replaced with their respective Cray compiler wrapper names::
+
+ ...
+ paths:
+ cc: cc
+ cxx: CC
+ f77: ftn
+ fc: ftn
+ ...
+
+As opposed to an explicit path to the compiler executable. This allows Spack
+to call the Cray compiler wrappers during build time.
+
+For more on compiler configuration, check out :ref:`compiler-config`.
+
+Setting defaults and using Cray modules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to use default compilers for each PrgEnv and also be able
+to load cray external modules, you will need to set up a packages.yaml.
+
+Here\'s an example of an external configuration for cray modules:
+
+.. code-block:: yaml
+
+ packages:
+ mpi:
+ modules:
+ mpich@7.3.1%gcc@5.2.0 arch=cray_xc-haswell-CNL10: cray-mpich
+ mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-haswell-CNL10: cray-mpich
+
+This tells Spack that for whatever package that depends on mpi, load the
+cray-mpich module into the environment. You can then be able to use whatever
+environment variables, libraries, etc, that are brought into the environment
+via module load.
+
+You can set the default compiler that Spack can use for each compiler type.
+If you want to use the Cray defaults, then set them under *all:* in packages.yaml.
+In the compiler field, set the compiler specs in your order of preference.
+Whenever you build with that compiler type, Spack will concretize to that version.
+
+Here is an example of a full packages.yaml used at NERSC
+
+.. code-block:: yaml
+
+ packages:
+ mpi:
+ modules:
+ mpich@7.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge: cray-mpich
+ mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-SuSE11-ivybridge: cray-mpich
+ buildable: False
+ netcdf:
+ modules:
+ netcdf@4.3.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge: cray-netcdf
+ netcdf@4.3.3.1%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge: cray-netcdf
+ buildable: False
+ hdf5:
+ modules:
+ hdf5@1.8.14%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge: cray-hdf5
+ hdf5@1.8.14%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge: cray-hdf5
+ buildable: False
+ all:
+ compiler: [gcc@5.2.0, intel@16.0.0.109]
+
+Here we tell spack that whenever we want to build with gcc use version 5.2.0 or
+if we want to build with intel compilers, use version 16.0.0.109. We add a spec
+for each compiler type for each cray modules. This ensures that for each
+compiler on our system we can use that external module.
+
+
+For more on external packages check out the section :ref:`sec-external_packages`.
