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?

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 1USERCFG[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.
