On the XT5m you have to use aprun command inside a batch job. So you first have to request resources for your job with qsub and then put your application with aprun onto the compute nodes.

Attention If you forget to use aprun your application will run on the login node!


Example:

#!/bin/bash
#
# 2 nodes:
#PBS -lmppwidth=16
# 8 cores/node: 
#PBS -lmppnppn=8

aprun -n 16 -N 8 application
