How to use Infiniband Card with MSMPI on Win7/8/10? RRS feed

  • Question

  • Does anyone know that how to use Infiniband Card with MSMPI on Win7/8/10?

    Our project needs MPI, OpenGL, Infiniband Card, but we don't know how to use IB card with MSMPI. We have tried Intel MPI, which has commands to use IB card, but in our attempt, the Intel MPI could not create OpenGL Windows.

  • If you're using HPC Pack to run MPI, there should be a environment variable to indicate the network you want to use for MSMPI. please Check command: "cluscfg listenvs" and "cluscfg setenvs", the env should be names as "CCP_MPI_NETMASK=x.x.x.x/x.x.x.x", this is the netmask that your IB card network.

    Of course you could override it when you submit mpi job in mpiexec commandline
