Hi, I read in a previous thread ( https://www.open-mpi.org/community/lists/users/2014/05/24475.php) that Jeff mentions it's possible for OpenMPI to pick up the openib transport if tcp is not requested explicitly.
So, does that mean if I do, --mca btl ^openib that it's still possible for OpenMPI to use Infiniband and not TCP? Is there a way to guarantee that a test is using TCP, but not IB?
