Hello,
I've browsed the web and haven't been able to find a solution to this
problem and the technical support for my cluster has somewhat left me in
the wind on this issue.
We've got Maui version 3.2.6p13, configured out of the box by my cluster
vendor running on SuSE 10.1 with pbs_server 2.1.3.
The system has 35 dual cpu, dual core compute nodes on it. When the
system is open and we submit a job using qsub -l nodes=32:ppn=4 (i.e.
looking for 128 procs), the job will start immediately and run.
However, if this job ever has to wait, the Maui scheduler puts it in
Batch hold. A checkjob reports that there is a Policy Violation, the
number of procs is too high (128 > 70) - output below.
The job will run if you use the "runjob" command but not if you do a
"releasehold" command.
The diagnose -n command reports that there are 35 nodes, and 140 procs.
The nodeallocationpolicy is set to minresource.
qmgr also reports the correct number of nodes/procs (output below)
So my question is this... where is maui getting this 70 from?
Obviously, the procs are available because the job runs with the use of
the runjob command. Is there another setting that was missed to make
this all work correctly? My vendor essentially suggested I change to
using the pbs scheduler instead but that seems like giving up on
something which seems like a simple matter.
Any help would be greatly appreciated.
Thanks,
Kelli
