No sweat. I got a lot from this community when I was starting out with
Condor -- it's nice to be able give back.

At the central manager. It applies to the condor_negotiator daemon.

If you want to set the multiplier for a user you can use the
condor_userprio command:

http://www.cs.wisc.edu/condor/manual/v7.0/condor_userprio.html#60734

Lets say I have a user who's a light user of the system (so their Real
User Priority is always high because they don't run many jobs) but I
don't want them to be able to take over the system when they do submit
jobs. I want the system to *think* they're a heavy user at all times.
I'll set their priority factor really high so their Effective User
Priority is always lousy (i.e. always high):

        > condor_userprio -setfactor user@mydomain 100

The docs for condor_userprio explain things a little more clearly.
