Hi Paul: I tried the running the same way as you did and I saw the same thing. I was using ClusterTools 8.2 (Open MPI 1.3.3r21324) and running on Solaris. I looked at the mpirun process and it was definitely consuming approximately 12 file descriptors per a.out process. burl-ct-v440-0 59

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
