The other suggestion is that if you are unable to get Open-MPI to work with the test application above, then ask about this at the Open-MPI issue tracker, which I guess is this one: Any chance you can go back to an older Open-MPI version, or is version 4 the only one you can use. What component will my OpenFabrics-based network use by default? v1.2, Open MPI would follow the same scheme outlined above, but would Help me understand the context behind the "It's okay to be white" question in a recent Rasmussen Poll, and what if anything might these results show?
