Thanks for the support!

A tricky question. OpenMP tends to be associated with low-latency 
parallelism, while MPI and PVM represent various forms of message 
passing mechanisms. In some cases, people have tried to write mixed MPI 
and OpenMP programs, where the distributed nodes are multiprocessor 
systems. One of the ASCI machines (I forget which color) uses 
multiprocessor nodes connected via a high-speed network.

I think we should just stick to low-latency parallelism in GOMP; 
otherwise, I think we're mixing what some people see as apples and oranges.
