No. Open MPI does not have MPD -- I think you're thinking of a different MPI implementation. :-)
If you can run Linux on all these machines, then hypothetically the heterogeneous flag would allow a single Open MPI job to run across all of them. I say "hypothetically" because I think we have done basic testing to ensure this stuff works, but it is used so infrequently (in reality, most people don't mix and match too often) that we don't stress test it, nor do we test it in exotic environments.
