[Condor-users] restricting no of jobs per user at site using Condor-G

["Dr Ian C. Smith" <i.c.smith@xxxxxxxxxxxxxxx>]

Hi,

I'm in the process of setting up a campus mini-
grid using Condor-G which is going very smoothly
so far. I've hit a snag in that one of the clusters
in the grid will only run a maximum of three
jobs per user concurrently. At present users'
jobs can go to this cluster if there are sufficient
free nodes but will wait on the queue
there when there may be spare resources elsewhere
later on. ( Globus is set up so that users get mapped
to their own account on the cluster not a generic "grid" one ).

So what I need is someway of expressing this via
a ClassAd or similar. As far as I can see
from the docs Condor-G can be used to restrict the
*total* number of grid jobs going to a site but
there's no simple way of doing this on a *per-user*
basis. Or is there ?

regards,

-ian.
