[torqueusers] queue limit

[Chris Evert]

Hello Chris, list,

I finally got around to trying this, and I seem to be limited to half 
the number I specify:

I have set USERCFG[chris]          MAXPROC=16 in maui.cfg (and restarted 
maui)
I then submitted several ppn=4 jobs and only two are running at a time

checkjob shows:



checking job 204645

for a running job, and for one waiting around:

checking job 204650

cannot select job 204650 for partition DEFAULT (job 204650 violates 
active HARD MAXPROC limit of 16 for user chris  (R: 4, U: 16)
)


What am I missing?  (A USERCFG[chris] PREJUDICE=2 configuration, perhaps:-)
Should I just multiply the ideal MAXPROC by 2?

Any help is appreciated,
Chris
