Subject: [OMPI devel] Regarding OpenMPI example apps
From: Bhargava Ramu Kavati (ramu.kavati_at_[hidden])

Hi,
I am trying to run the example applications in OpenMPI using the command
"mpirun --prefix /usr/local/ --mca btl_openib_cpc_include rdmacm -np 4 -H
<IP> hello_c"

But I am getting the below warning
"WARNING: No preset parameters were found for the device that Open MPI
detected:"

Also at the end (just before the above command returns), I see messages like

"[localhost.localdomain:28537] 3 more processes have sent help message
help-mpi-btl-openib.txt / no device params found
[localhost.localdomain:28537] Set MCA parameter "orte_base_help_aggregate"
to 0 to see all help / error messages"

Am I missing anything with the command that I used (OR) can we ignore these
messages ? Please suggest me.

Thanks & Regards,
Ramu
