IntelMPI over Mellanox 10GB RDMA chipset

Hi

What is the best DAPL provider to used with IntelMPI 5.1  when running with a 10Gb RDMA chipsset from Mellanox?

Currently I'm using I_MPI_DAPL_PROVIDER=ofa-v2-scm-roe-mlx4_0-1

I added some others extra parameters to workaround the resource limitation that we have on the chip

  export I_MPI_DAPL_RDMA_RNDV_WRITE=on

   export I_MPI_RDMA_MAX_MSG_SIZE=1048576

Thanks

Thierry
