Hi Ted
From what I can tell, you are not using Open MPI, but mpich's mpirun.
You might want to ask for help on their mailing list.

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:

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.
