[torqueusers] queue limit

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

State: Running
Creds:  user:chris  group:users  class:short  qos:DEFAULT
WallTime: 00:00:52 of 1:12:00:00

PE:  4.00  StartPriority:  4320

for a running job, and for one waiting around:

checking job 204650

State: Idle
Creds:  user:chris  group:users  class:short  qos:DEFAULT

IWD: [NONE]  Executable:  [NONE]
Bypass: 0  StartCount: 0
PartitionMask: [ALL]
PE:  4.00  StartPriority:  4320
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
