Hi all,

I have a cluster where both HCA's of blade are active, but connected to different subnet.
Is there an option in MPI to select one HCA out of available one's? I know it can be done by making changes in openmpi code, but i need clean interface like option during mpi launch time to select mthca0 or mthca1?

Any help is appreciated. Btw i just checked Mvapich and feature is there inside.

Regards
