I added the $PBS_NODEFILE in the script in my last email below. It show only one node here is the output =============== node47.beowulf.cluster node47.beowulf.cluster node47.beowulf.cluster node47.beowulf.cluster This job has allocated 4 nodes Hello World! from process 1 out of 4 on node47.beowulf.cluster Hello World! from process 2 out of 4 on node47.beowulf.cluster Hello World! from process 3 out of 4 on node47.beowulf.cluster Hello World! from process 0 out of 4 on node47.beowulf.cluster ===============
