Hi Ole (and Jeffrey),

Thanks for the pointer - those are some very useful scripts. I couldn't get showslurmlimits or showslurmjobs to get quite what I was after (it wasn't showing me memory usage). However, it pointed me in the right direction - the scontrol command. I can run the following:

scontrol show assoc_mgr flags=qos

and part of the output reads:

    User Limits
	MaxJobsPU=N(2) MaxJobsAccruePU=N(0) MaxSubmitJobsPU=N(2)

Which is exactly what I'm looking for. The values outside the brackets are the qos limit, and the values within are the current usage.

Hi Mike,

Would the "showuserlimits" tool give you the desired information?
