have you tried to change the priority with setspri after the job is in the queue to see if it correctly alters the priority?  this may help pinpoint if the QOS is not set up correctly or it's a problem with job submission.

I'm having trouble getting the Maui QOS to work.  I started by following the example in the admin doc and I've experimented to to no avail.

 

My QOS related variables in maui.cfg currently look like this:

 

QOSWEIGHT 1

QOSCFG[low] PRIORITY=1

QOSCFG[med] PRIORITY=10

QOSCFG[high] PRIORITY=100

 

I submit my jobs with qsub -W x:qos:med somejob

 

The syntax I saw in the archives had "-W x:QOS:med", but when I try that, none of my jobs run.  As it is I have a test case that submits a bunch of low priority jobs followed by a high priority job.  Each job grabs half the nodes, so the first two start running and the rest go in the queue.  When a job finishes, the processing continues in FIFO order rather than the high priority job getting taking precedence.

 

Any hints on how to debug would be appreciated.  I've looked at "diagnose -Q", but it doesn't tell me much.  I am using xpbs to monitor the queue.
