Easiest way to do this is to open a MINGW shell first and then add mpiexec to the path by doing C:\> set PATH=%PATH% %MSMPI_BIN%Ĭheck that mpiexec and gcc both work. Msmpi.dll is present in %SYSTEMROOT%\System32.īefore going further make sure that mingw and mpiexec are added to path. %MSMPI_INC% is the mpi include directory. MSMPI_LIB64=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\圆4\ MSMPI_LIB32=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x86\ MSMPI_INC=C:\Program Files (x86)\Microsoft SDKs\MPI\Include\ MSMPI_BIN=C:\Program Files\Microsoft MPI\Bin\ Doing "set MSMPI" in a cmd shell will show the directories of interest. Upon installation, some environment variables are set-up. We need msmpi.lib and msmpi.dll and the headers files for linking purposes. MSMPI provides "mpiexec.exe" MSMPI SDK provides the MPI libraries and header files. We need to download 3 items: mingw-w64, MSMPI and MSMPI SDKĭownload and Install mingw-w64 somewhere.ĭownload and install MSMPI and MSMPI SDK from microsoft. These are instructions to get Mingw + MPI going on windows the easy way. This is tested on Windows 7 and and Windows 10 and gcc version 7.1.0 (x86_64-posix-seh-rev2, Built by MinGW-W64 project). Gfortran, gcc on Windows with MPI MPI + GCC + GFORTRAN on Windows By Abhilash Reddy M.
