PBS - restrict total number of processors per user

Hello everyone!

I am a bit inexperienced with administering queueing programs. I installed Torque (a PBS derivative) on a Linux cluster and it is running well. There is one annoying problem though: users can run massively parallel jobs and serial jobs too. Almost all users do a mix of the two. I would like to restrict the total number of processors per user at any given time, say 40 processors, whether it is 20 jobs x 2 CPUs or 2 jobs x 20 CPUs, etc. Is there a way to do that in PBS/Torque with or without Moab/Maui?

Thanks in advance for any suggestions!

atq [-c] [-n] [username]... DESCRIPTION
The atq utility displays the at jobs queued up for the current user. at(1) is a utility that allows users to execute commands at a later date.

The following options are supported: -c Displays the queued jobs in the order they were created (that is, the time that the at command was given). -n Displays only the total number of jobs currently in the queue. FILES
