Hi Ricardo

1. I think qrun will use the "worst possible node".
See 'man qrun'.

2. Which scheduler are you using?  There were problems
(job in Q state forever) reported
with pbs_sched on Torque 4.X (probably fixed at this point).
Maui should start the jobs.

3. Did you enable scheduling?
qmgr -c 'set server scheduling = True'

I hope this helps,
Gus Correa
