[mvapich-discuss] Running osu benchmark tests via OFED Stack

[Bhargava Ramu Kavati]

Hi,
I have Infiniband setup (two machines) connected back-to-back using Mellanox
infiniband adapters.  I am trying to OSU MPI benchmark tests via OFED Stack
and I am using MVAPICH2 version 1.4.1.  Below is the command I have tried.

"mpirun_rsh -np 2 -hostfile tmp_host_file MV2_IBA_HCA=mlx4_0 osu_latency"
here tmp_host_file has two hosts as test1, test2

But I am getting the below error
"This test requires exactly two processes
MPI process (rank: 1) terminated unexpectedly on test2
Exit code -5 signaled from test2

This test requires exactly two processes
MPI process (rank: 0) terminated unexpectedly on test1"

am I missing anything in the above command.  Please suggest me.

Thanks & Regards,
Ramu
