[Mauiusers] Node Priority

[Roy Dragseth]

The simplest way is to reverse the nodelist in torque.

You could also take a peek at the NODEALLOCATIONPOLICY parameter in maui.  We 
have this

NODEALLOCATIONPOLICY PRIORITY
NODECFG[DEFAULT] PRIORITYF=JOBCOUNT

in our maui.cfg, which will pack jobs into the most loaded nodes keeping as 
many nodes free as possible.  Might be possible to tweak this to your liking.
