[OMPI users] need a tool and its use to verify use of infiniband network

[SOPORTE MODEMAT via users]

Hello guys.

I would like you to help me with one tool or manner to verify the use of 
infiniband network interface when I run the command:

/opt/mpi/openmpi_intel-2.1.1/bin/mpirun --mca btl self,openib,vader python 
mpi_hola.py
Is there a way to verify that the infiniband interface is being used? If so, 
how can I do it?

Thank you in advance for your help

Saludos cordiales.
