You could even set a h_cpu limit on this queue to avoid abuse - jobs abusing this queue would get killed after 5 minutes or so. The overall slot count used in this cluster queue you can limit in an RQS.

I didn't mention it: you oversubscribe by intention. In case you have further queues on each host, the RQS for limiting the overall slot count will need two entries:

limit name parents queues parent.q hosts {*} to slots=1
limit name slots hosts {*} to slots=$num_proc

The first matching rule will end the RQS. The second RQS for the parent.q overall use it like usual:

limit name parents queues parent.q to slots=17

Please adjust the numbers to your needs. You could even run all parents on one machine, but I would spread it around.
