Hi Paul:
I tried the running the same way as you did and I saw the same thing. I

Hi OpenMPI folks,
We use Sun MPI (Cluster Tools 8.2) and also native OpenMPI 1.3.3 and we
wonder us about the way OpenMPI devours file descriptors: on our
computers, ulimit -n is currently set to 1024, and we found out that we
may run maximally 84 MPI processes per box, and if we try to run
