This is indeed a question that we get asked a lot. We have so far not though about adding more advanced scheduling capabilities for the cooperative threads. With the slot system, if you have 48 core available in the cluster, and running 8 jobs, each job will only use 6 cores each. With cooperative threading, each job runs on all the 48 cores. We have tested something like 5,000 concurrent jobs on same cluster, but essentially they may be competing for the same resources, so you'll need to do your capacity planning accordingly. Simple way to work around that would be to create separate Jet nodes (a Jet node is very lightweight) so you could have separate execution pools.
