MPI is a standard interface -# (defined by the MPI forum) for which many implementations are -# available. All of these implementations have somewhat different -# compilation approaches (different include paths, libraries to link -# against, etc.), and this module tries to smooth out those differences. -# -# This module will set the following variables: -# MPI_FOUND TRUE if we have found MPI -# MPI_COMPILE_FLAGS Compilation flags for MPI programs -# MPI_INCLUDE_PATH Include path(s) for MPI header -# MPI_LINK_FLAGS Linking flags for MPI programs -# MPI_LIBRARY First MPI library to link against (cached) -# MPI_EXTRA_LIBRARY Extra MPI libraries to link against (cached) -# MPI_LIBRARIES All libraries to link MPI programs against -# MPIEXEC Executable for running MPI programs -# MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the -# number of processors to run on -# MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the -# executable to run. -# MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after all other flags. -# -# This module will attempt to auto-detect these settings, first by -# looking for a MPI compiler, which many MPI implementations provide -# as a pass-through to the native compiler to simplify the compilation -# of MPI programs. The MPI compiler is stored in the cache variable -# MPI_COMPILER, and will attempt to look for commonly-named drivers -# mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and -# recognized, it will be used to set all of the module variables. To -# skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in -# the CMake cache. -# -# If no compiler driver is found or the compiler driver is not -# recognized, this module will then search for common include paths -# and library names to try to detect MPI. -# -# If CMake initially finds a different MPI than was intended, and you -# want to use the MPI compiler auto-detection for a different MPI -# implementation, set MPI_COMPILER to the MPI compiler driver you want -# to use (e.g., mpicxx) and then set MPI_LIBRARY to the string -# MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI -# will run again with the newly-specified MPI_COMPILER. -# -# When using MPIEXEC to execute MPI applications, you should typically -# use all of the MPIEXEC flags as follows: -# ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE -# ${MPIEXEC_POSTFLAGS} ARGS -# where PROCS is the number of processors on which to execute the program, -# EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the -# MPI program. - -#============================================================================= -# Copyright 2001-2009 Kitware, Inc. -# -# Distributed under the OSI-approved BSD License (the "License"); -# see accompanying file Copyright.txt for details. -# -# This software is distributed WITHOUT ANY WARRANTY; without even the -# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. -# See the License for more information. -#============================================================================= -# (To distributed this file outside of CMake, substitute the full -# License text for the above reference.) - -# This module is maintained by David Partyka <dave.partyka@kitware.com>. - -# A set of directories to search through in addition to the standard system paths -# that find_program will search through. -# Microsoft HPC SDK is automatically added to the system path -# Argonne National Labs MPICH2 sets a registry key that we can use. - -set(_MPI_PACKAGE_DIR - mpi - mpich - openmpi - lib/mpi - lib/mpich - lib/openmpi - "MPICH/SDK" - "Microsoft Compute Cluster Pack" - ) - -set(_MPI_PREFIX_PATH) -if(WIN32) - list(APPEND _MPI_PREFIX_PATH "[HKEY_LOCAL_MACHINE\\SOFTWARE\\MPICH\\SMPD;binary]/..") - list(APPEND _MPI_PREFIX_PATH "[HKEY_LOCAL_MACHINE\\SOFTWARE\\MPICH2;Path]") -endif() - -foreach(SystemPrefixDir ${CMAKE_SYSTEM_PREFIX_PATH}) - foreach(MpiPackageDir ${_MPI_PREFIX_PATH}) - if(EXISTS ${SystemPrefixDir}/${MpiPackageDir}) - list(APPEND _MPI_PREFIX_PATH "${SystemPrefixDir}/${MpiPackageDir}") - endif() - endforeach(MpiPackageDir) -endforeach(SystemPrefixDir) - -# Most mpi distros have some form of mpiexec which gives us something we can reliably look for. -find_program(MPIEXEC - NAMES mpiexec mpirun lamexec - PATHS ${_MPI_PREFIX_PATH} - PATH_SUFFIXES bin - DOC "Executable for running MPI programs." - ) - -# call get_filename_component twice to remove mpiexec and the directory it exists in (typically bin). -# This gives us a fairly reliable base directory to search for /bin /lib and /include from. -get_filename_component(_MPI_BASE_DIR "${MPIEXEC}" PATH) -get_filename_component(_MPI_BASE_DIR "${_MPI_BASE_DIR}" PATH) - -# If there is an mpi compiler find it and interogate (farther below) it for the include -# and lib dirs otherwise we will continue to search from ${_MPI_BASE_DIR}. -find_program(MPI_COMPILER - NAMES mpiCC mpicc mpic++ mpicxx - HINTS "${_MPI_BASE_DIR}" - PATH_SUFFIXES bin - DOC "MPI compiler.
