Subject: [OMPI users] open mpi 1.3 RDMA_CM_EVENT_CONNECT_ERROR
From: viral.mehta_at_[hidden]

Hi all,
I successfully installed OpenMPI-1.3. I am trying to run OpenMPI over iWARP.
But I am getting error

RDMA_CM_EVENT_CONNECT_ERROR

I tried to run with more debug messages
mpirun --mca orte_base_help_aggregate 0 -np 2 -display-map -v -host
100.168.54.49,100.168.54.50
/usr/mpi/gcc/openmpi-1.3/tests/osu_benchmarks-3.0/osu_bw

And I got
[qa49:06449] *** Process received signal ***

Am I doing something wrong ??

Surprisingly,
mpirun --mca orte_base_help_aggregate 0 -np 2 -display-map -v -host
100.168.54.50,100.168.54.49
/usr/mpi/gcc/openmpi-1.3/tests/osu_benchmarks-3.0/osu_bw
is working fine (notice just host arguments are swapped)

Thanks,
Viral
