[Condor-users] Hard limit on the number of jobs from a specific user

["Hrant P. Hratchian" <hhratchi@xxxxxxxxxxx>]

I take care of a cluster dedicated to our research group and we have a need to place a hard limit on the number of jobs any one user can have running at any given time.  The calculations we do, unfortunately, do not checkpoint well so preemption is not a good option for us to achieve fair use by all users.  (The problem is that many of our jobs run for days at a time, so the solution for people with idle jobs is not to just wait patiently for the other person's jobs to finish.)

I can't seem to find any macros for the configuration file that would allow a hard limit setting.  I hope that I'm just missing it.

Can someone point me in the right direction or offer a work-around?  Is there a way to have the remote nodes only accept a job if the user's priority level is below a set threshold?

Thanks in advance,
HPH
