[mvapich-discuss] Fatal error in MPI_Init

[Bhargava Ramu Kavati]

Hi,
I am trying to run OSU MPI test apps with MVAPICH2-1.7 on my Infiniband
setup (two machines connected back-to-back).  I see the error at an early
stage i.e during MPI_Init() with the command

"mpirun_rsh  -np 2 -hostfile /root/hostfile_test
/root/ofed_pkgs/mvapich2-1.7/osu_benchmarks/osu_latency"


The complete error thrown is
*[cli_0]: aborting job:
Fatal error in MPI_Init:
Other MPI error

[test1:mpispawn_0][readline] Unexpected End-Of-File on file descriptor 5.
MPI process died?
[test1:mpispawn_0][child_handler] MPI process (rank: 0, pid: 15261) exited
with status 1
[test1:mpispawn_0][mtpmi_processops] Error while reading PMI socket. MPI
process died?

[cli_1]: aborting job:
Fatal error in MPI_Init:
Other MPI error

[test2:mpispawn_1][readline] Unexpected End-Of-File on file descriptor 5.
MPI process died?
[test2:mpispawn_1][mtpmi_processops] Error while reading PMI socket. MPI
process died?
[test2:mpispawn_1][child_handler] MPI process (rank: 1, pid: 16453) exited
with status 1*

Can you please guide me what are all the OFED specific params
checked/queried during MPI_Init().

Thanks & Regards,
Ramu
