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.

thank you for the information, sounds like i will have to wait until the beta
