What version of OMPI are you talking about?

Hello everyone,
I am trying to get the maximum performance out of my two node testing setup.
Each node consists of 4 Sandy Bridge CPUs and each CPU has one directly
attached Mellanox QDR card. Both nodes are connected via a 8-port Mellanox
switch.
So far I found no option that allows binding mpi-ranks to a specific card, as
it is available in MVAPICH2. Is there a way to change the round robin behavior
of openMPI?
Maybe something like "btl_tcp_if_seq" that I have missed?
Kind regards,
Tobias
