Running MPI jobs in torque has been discussed many many times. Please see the
mailing list archives.
When you run mpdboot outside of torque, then mpirun inside of the job has no
idea which nodes to use.
One solution is to run mpdboot inside of the job.
mpboot -f $PBS_NODEFILE
The other (better) solution is to use mpiexec from OSC
http://www.osc.edu/~pw/mpiexec/. It uses torque's built-in TM interface to
launch and clean up the jobs.
