Just to make sure, because I have to use open mpi for this program:
I'm using the default mpirun command.
When I type "man mpirun", these are the first few lines:
MPIRUN(1) OPEN MPI COMMANDS MPIRUN(1)
NAME
orterun, mpirun, mpiexec - Execute serial and parallel jobs in Open
MPI.
Note: mpirun, mpiexec, and orterun are all exact synonyms for each
other. Using any of the names will result in exactly identical behav-
ior.

Thanx for the reply.
I guess I should go back a step: I had used the openmpi version on my system
which is simply:
"mpirun -machinefile $PBS_NODEFILE -np $NPROCS ${CODE}
>/ul/tedhyu/fuelcell/HOH/test/HH.out"
This did not work because I was just getting a blank output.
I tried this older version because at least i was getting an output.
"/opt/mpich-1.2.5.10-ch_p4-gcc/bin/mpirun -machinefile $PBS_NODEFILE -np
$NPROCS ${CODE} >/ul/tedhyu/fuelcell/HOH/test/HH.out" I think this older
version is failing me for whatever reason. Do you have any clue? I read
somewhere that new versions of mpirun adds extra commandline arguments to the
end of the line. Therefore the newer version of mpirun may be not be giving an
output because it sees all extra commandline arguments after my output file
>/ul/tedhyu/fuelcell/HOH/test/HH.out
This is where I'm reading that there are extra commandline arguments for a
version of mpirun:
https://lists.sdsc.edu/pipermail/npaci-rocks-discussion/2008-February/029333.html
Again, I'm new at this, and I'm just guessing. Any ideas of where to turn
would be helpful!

Please note, that you are mixing Open MPI (API/Library) with MPICH
(mpirun). This is a mistake I like to make, too. If you use
the ompi mpiexec program, it probably works.
