    WinOF v5.22 and Platform MPI problem on ConnectX-3 cards

    digitalmg

      Dears,

      I need to use Platform MPI 9.1.3 with my application being run in -IBAL mode.

      Unfortuantlly no driver released later than WinOF v2.1.2 ( 3.xx , 4.xx , 5.xx ) won't be detected by MPI and it fires error like this :

      Rank 0:1: MPI_Init: didn't find active interface/port

      Rank 0:1: MPI_Init: Can't initialize RDMA device

      Rank 0:1: MPI_Init: Internal Error: Cannot initialize RDMA protocol

       

      if -IBAL switch is removed, TCP will be utilized and the program works but infiniband is not implemented.

      Please let me know what's the reason beyond this. Why Mellanox released so many drivers so far which are not compatible with Platform MPI ?

      Am I missed a tweak ?

       

      Thanks
