[OMPI devel] selectively bind MPI to one HCA out of available ones
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 Neeraj Chourasia (MTS) Computational Research Laboratories Ltd.
