[mvapich-discuss] problems running osu benchmarks with RDMA CM

[Jesus Camacho Villanueva]

Hello,

I can run osu benchmarks without any problem, but when running them with
the rdma connection manager they crash.
Previously I have been running performance tests for Infiniband using the
rdma connection manager without problems.
Now when using the MV2_USE_RDMA_CM option, I obtain the next output:

# mpirun_rsh -hostfile host -np 2 MV2_USE_RDMA_CM=1 ./osu_acc_latency
[compute-0-1.local:mpi_rank_1][ib_cma_event_handler]

Can someone help me with this?

Best regards,
Jesus
