I think you'll need Moab to handle the flexlm integration, and at least
Maui or Moab to handle the time-based machine pool.  But otherwise,
TORQUE will do what you want.

The scheduler included with TORQUE is really simple and basicly just to
get started.  Real scheduling is done with Maui or Moab.

It is definitely a complex system, but that is true for any resource
management.  I'd say the initial install and config is straight forward,
but plan for regular config adjustments over time.  Requirements seem to
always change and TORQUE+Moab/Maui is a very flexible system.

Don't forget that TORQUE is open source and SGE is closed.  TORQUE
development is very rapid and we are always accepting patches for the
larger community.  If TORQUE doesn't do what you want today, it
certainly can tomorrow.

Maui is also open but doesn't move as fast as TORQUE.  While Moab is
closed, it is very flexible and CRI is very responsive to user feature
