I have installed Materials studio on a high performance computing server and we have observed interesting behavior; when I run the case with 1 node or more, the server still uses one node and do not utilize the rest. I was wondering if I am missing something on the installation and running or the software needs to be modified in order to to be able to use more nodes. Any help would be appreciated.

Here is the summary of the code I got:

#!/bin/bash

#PBS -l walltime=00:59:00

#PBS -l nodes=4:ppn=16:IB

cd /.../MaterialsStudio7.0

source setup.sh

cd etc/Gateway/

./gwstart

unset I_MPI_PMI_LIBRARY

source /.../MaterialsStudio7.0/etc/Scripting/bin/RunMatScript.sh

MSBIN=/.../MaterialsStudio7.0/etc/Scripting/bin/RunMatScript.sh

BASENAME=script

## without .pl at the end!

cd "\$PBS_O_WORKDIR"

NN=\$(wc -l < \$PBS_NODEFILE)

\$MSBIN -np \$NN \$BASENAME
