    Hello,

    I try to find out, which transport type is used as default with MS-MPI and Mellanox Connect-X 2 (Reliable Datagram/Connection etc.).

    Am I right, when I assume that the MPI library is arranging the transport type?

    Hi,

    Mellanox Connect-X 2 is Infiniband adaptor. By default, all Infiniband adaptor will use NetworkDirect (RDMA) for transport.

    MS-MPI will use Network Direct if possible.  You do need to setup the drivers to enable it, however.

    Network Direct only exposes Reliable Connected services when running over InfiniBand.
