From 3aaa077c9f530a020eb457c8981c88d422d5c205 Mon Sep 17 00:00:00 2001 From: Axel Huebl Date: Tue, 30 Aug 2016 11:44:23 +0200 Subject: libSplash: Add Spack Package Adds a package for [libSplash](https://github.com/ComputationalRadiationPhysics/libSplash), a high-level library around serial and parallel HDF5 for regular grids and particle data sets. ``` libSplash aims at developing a HDF5-based I/O library for HPC simulations. It is created as an easy-to-use frontend for the standard HDF5 library with support for MPI processes in a cluster environment. While the standard HDF5 library provides detailed low-level control, libSplash simplifies tasks commonly found in large-scale HPC simulations, such as iter- ative computations and MPI distributed processes. ``` libSplash is a dependency for [PIConGPU](http://picongpu.hzdr.de), an open-source, many-core, fully-relativistic particle-in-cell code and further software developed at [Helmholz-Zentrum Dresden - Rossendorf](https://www.hzdr.de). libSplash builds in two versions, one without MPI writing domain-decomposed posix-style HDF5 files per process and one (default) with MPI and MPI-I/O ("parallel HDF5") support aggregating into a single file per MPI communicator. libSplash is used in conjunction with [openPMD](http://openPMD.org), see also [github.com/openPMD/](https://github.com/openPMD/). --- .../repos/builtin/packages/libsplash/package.py | 59 ++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 var/spack/repos/builtin/packages/libsplash/package.py (limited to 'var') diff --git a/var/spack/repos/builtin/packages/libsplash/package.py b/var/spack/repos/builtin/packages/libsplash/package.py new file mode 100644 index 0000000000..dd47ea0993 --- /dev/null +++ b/var/spack/repos/builtin/packages/libsplash/package.py @@ -0,0 +1,59 @@ +############################################################################## +# Copyright (c) 2013-2016, Lawrence Livermore National Security, LLC. +# Produced at the Lawrence Livermore National Laboratory. +# +# This file is part of Spack. +# Created by Todd Gamblin, tgamblin@llnl.gov, All rights reserved. +# LLNL-CODE-647188 +# +# For details, see https://github.com/llnl/spack +# Please also see the LICENSE file for our notice and the LGPL. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU Lesser General Public License (as +# published by the Free Software Foundation) version 2.1, February 1999. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the IMPLIED WARRANTY OF +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is a bug in Spack's dependency resolution. A workaround for this is to tell it to always depend on hdf5. ``` @davydden ``` to expand on @adamjstewart comment, spack will make a union of dependencies, i.e. hdf5@1.8.6: + hdf5+mpi = hdf5:1.8.6:+mpi, that's why it works. ``` thank you for the hint! --- var/spack/repos/builtin/packages/libsplash/package.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'var') diff --git a/var/spack/repos/builtin/packages/libsplash/package.py b/var/spack/repos/builtin/packages/libsplash/package.py index dd47ea0993..0659f7d650 100644 --- a/var/spack/repos/builtin/packages/libsplash/package.py +++ b/var/spack/repos/builtin/packages/libsplash/package.py @@ -46,8 +46,8 @@ class Libsplash(Package): description='Enable parallel I/O (one-file aggregation) support') depends_on('cmake', type='build') - depends_on('hdf5@1.8.6:', when='~mpi') - depends_on('hdf5@1.8.6:+mpi', when='+mpi') + depends_on('hdf5@1.8.6:') + depends_on('hdf5+mpi', when='+mpi') depends_on('mpi', when='+mpi') def install(self, spec, prefix): -- cgit v1.2.3-60-g2f50
