The nightly snapshot fixes the issue for me. Many thanks!

@John: Did you also recompile your sample application? From what I understand, the issue is not in hydra but in the MPI library (please correct me if I'm wrong, Pavan).

No, my initial diagnosis was incorrect. The problem was completely inside hydra (mpiexec), so the application doesn't need to be recompiled. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
