Just to make sure I'm reading this right -- 128.109.34.20 is supposed
to be routable to 130.207.252.131, right? Can you ssh directly from
one machine to the other? (I'm guessing that you can because OMPI was
able to start processes) Can you ping one machine from the other?
Most importantly -- can you open arbitrary TCP ports between the two
machines? (i.e., not just well-known ports like 22 [ssh], etc.)
