This articles describes how to set up and configure Microsoft MPI (MS-MPI) on the Windows platform.

 

Feko supports a number of message passing interface (MPI) implementations which are platform and system dependent.

If the MS-MPI implementation is required and it is not the default for the specific platform, it will need to be configured.

MS-MPI is shipped as part of the Feko installation but it is not installed.

 

imageNote: The following defaults are used for MPI:

  • All platforms (except Windows HPC): Intel MPI
  • Windows HPC:                                        MS-MPI

 

How to set up MS-MPI:

 1.   Browse to <ALTAIR_HOME>/mpi/win64/ms-mpi where<ALTAIR_HOME> points to the Altair installation folder.

imageNote: For some versions of Feko, MS-MPI was located at <ALTAIR_HOME>/feko/mpi/ms-mpi.

 2.   Run MSMpiSetup.exe.

 3.  Set the following environment variables:

    • FEKO_WHICH_MPI  = 13
    • MSMPI_BIN  should normally be set automatically by the MS-MPI installer and point to the installed Microsoft MPI/Bin folder (for example: C:\Program Files\Microsoft MPI\Bin).
