Hello All

I am using mpi 3.1 and was wondering if there is a way to set up mpi so that it will use multiple network ports when i do an mpi_send...

Thanks

MPI 4.0 (beta due in November) should support use of multiple ports per node by splitting messages, a strategy which has been effective for messages > 2KB in some past installations. As InfiniBand is in general use where such capacity is in demand, the reduced performance of current dual port IB adaptors is an obstacle.
