Hi Ralph,

The allocation looks fine, but why it show number of slots as 1. The
executions host has 4 processor, in nodes file also defined np=4.

====================== ALLOCATED NODES ======================

 Data for node: Name: node56.beowulf.cluster Num slots: 1 Max slots: 0

=================================================================

 ======================== JOB MAP ========================

 Data for node: Name: node56.beowulf.cluster Num procs: 4
        Process OMPI jobid: [17538,1] Process rank: 0
        Process OMPI jobid: [17538,1] Process rank: 1
        Process OMPI jobid: [17538,1] Process rank: 2
        Process OMPI jobid: [17538,1] Process rank: 3

 =============================================================
Hello World! from process 0 out of 4 on node56.beowulf.cluster

Hello World! from process 1 out of 4 on node56.beowulf.cluster
