Thanks to all that replied.
My fairshare policy is working now.
New configs
Queuetime 0
FSWEIGHT 1
FSUSERWEIGHT 1
FSGROUPWEIGHT 1
USERCFG[DEFAULT] FSTARGET=5.0 # based on 20 active users.
Thanks again

Hi,
I am trying to configure the fairshare policy or a solution, so that
users who submit 100 jobs can not monopolize the cluster. The cluster
consists of 32 dual processor nodes. Torque-2.0.0p8 and maui-3.2.6p16
are installed on a system running Centos 4. All users are in the
group students and right now, there is only one queue. There are no
restrictions on the number of jobs a user can run and it is a FIFO
operation.
UserA submits 100 jobs and monopolizes the cluster and also has jobs
in the queue. UserB submits 10 jobs and has to wait until all of
userA's jobs, both running/queued, have finished before userB jobs
will run. I want to be able to properly weight the jobs in the
queue, so that even if userA's jobs have been queued long, userB's
jobs will run first.
Mary,
I gave a short 30m tutorial on Torque and Maui the other day which
might answer some of your questions hopefully?
http://indico.cern.ch/materialDisplay.py?contribId=34&sessionId=21&materialId=slides&confId=3738
the TorqueMauiTutorial* documents are all the same, just different
formats. The .mov format is probably the best.

It seems the fairshare policy with historical usage would be the way
to go, but I am not sure if I have the selected the correct
parameters or configured them properly. Here is the relevant
maui.cfg parameters I have enabled.
QUEUETIMEWEIGHT 10
FSPOLICY PSDEDICATED
FSDEPTH 4
FSINTERVAL 00:06:00
FSDECAY 0.50
FSWEIGHT 1
FSUSERWEIGHT 1
FSGROUPWEIGHT 1
USERCFG[DEFAULT] FSTARGET=70 ( hoping this give any user a
fairshare target of 70. Is this the parameter I should be tweaking
the most?)
Any help would be great.
Thanks
Mary Ellen
