FWIW, I can run Open MPI v1.4.2beta on my OFED 1.4.1 cluster over IB devices using RDMA CM with no problems. I added some debug statements in OMPI showing which rdma_cm_bind's it attempts, just to be sure. Here's a run across 2 nodes, each with a single 2-port mthca (each port connected to a different IB subnet, not that that matters): $ mpirun -np 2 --bynode --mca btl_openib_cpc_include rdmacm ring [svbu-mpi025:05592] FAILED to bind to 127.0.0.1 [svbu-mpi025:05592] FAILED to bind to 172.29.218.165 [svbu-mpi025:05592] SUCCEEDED to bind to 10.10.30.165 [svbu-mpi025:05592] SUCCEEDED to bind to 10.10.20.165 [svbu-mpi026:05529] FAILED to bind to 127.0.0.1 [svbu-mpi026:05529] FAILED to bind to 172.29.218.166 [svbu-mpi026:05529] SUCCEEDED to bind to 10.10.30.166 [svbu-mpi026:05529] SUCCEEDED to bind to 10.10.20.166 ...
