Yes, this limits the number of jobs in the cluster per user, whether they are
running or waiting. But there is maxujobs in `qconf -msconf` to control the
running ones.

I don't know which particular slide you refer to. By default only "slots", i.e.
requested "cores" one could say, can be controlled by an RQS.
If you want to control "jobs" by an RQS, you will need to define a complex with
the value of consumable set to "JOB" (`man complex`) and attach an arbitrary
high value to `qconf -me global` to have something to consume them from.
