In Torque, if you use Maui or Moab as the scheduler, you get far more control. In the above request using Maui with a parameter JOBNODEMATCHPOLICY EXACTNODE in the maui.conf file enables nodes=2:ppn=2 to use two separate nodes with two processes (cores) per node. So the combination of a policy scheduler and a resource manager have configuration files to coordinate, but that allows for flexibility and control in cluster job management. ----------------------- Cordially, Tom _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
