We don't really have this kind of fine-grained processor affinity
control in Open MPI yet.
Is there a reason you want to oversubscribe cores this way? Open MPI
assumes that each process should be as aggressive as possible in
terms of performance -- spinning heavily until progress can be made
on message passing, etc.
