I built the Nasa Overflow 1.8ab code yesterday with openmpi-1.0a1r7632. It runs fine with 4 or 8 opteron processors on a myrinet linux cluster.

But if I increase the number of processors to 20, I get errors like this :

It's been a few years, and I don't remember the specific MPI implementation, but I did have a similar-sounding problems on a cluster when the number of processors wasn't a power of 2. Have you tried running with 10 processors, just to see what happens?
