[torqueusers] Job with high proc count will not schedule

[Ken Nielson]

Jonathan,

What torque calls a node and what Moab or Maui call a node are not the 
same thing. Using qrun the largest number you can submit with the -l 
nodes= option is five. That is because torque sees that there are only 5 
nodes in the cluster. However, you can get the other cores scheduled 
using the following syntax on qsub:

qsub -l nodes=5:ppn=4 <script>

This tells torque to find 5 nodes with at least 4 free processes and 
schedule those resources when qrun is executed.

I hope this helps.

Ken
