This confused me for awhile. Torque use implies a resource manager to
monitor the resources and offer them up to a Scheduler. 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.
