Essentially the examples given on this web is no difference from what I did. Only thing new is, I suppose "qsub -I " is for interactive mode. When I did this: qsub -I -l nodes=7 mpiblastn.sh It hangs on "qsub: waiting for job 798.nagrp2.ansci.iastate.edu to start". >>UNIX_PROMPT> qsub -l nodes=6:ppn=2 /path/to/mpi_program >>where "mpi_program" is a file with one line: >> /path/to/mpirun -np 12 /path/to/my_program > >Can you please try this jobscript instead: > >#!/bin/sh >set | grep PBS >/path/to/mpirun /path/to/my_program > >All should be handled by Open MPI automatically.
