I didn't realize it was an MPI type program, so I ran is using the QSNet version of mpirun and OpenMPI. The process does start and runs through 0: and 2:, which i assume are packet sizes, but freezes at that point. We have an existing XC cluster from HP, that we're trying to convert from XC to standard RHEL5.3 w/ Slurm and OpenMPI. All i want to be able to do is load RHEL5 and the Quadrics NIC drivers, and run OpenMPI jobs between these two nodes I yanked from the cluster before we switch the whole thing over.
