I see. Thank you very much. For my current problem giving priority according to queue priority would kinda solve it. For experimentation I will sometimes enqueue a task and then later enqueue a another one of a different kind, but what happens is that even though this could be trivially solved, I will have to wait for the first one to finish. I guess this is only a problem for people with small "clusters" where SLURM does not make sense, but no scheduling at all is also suboptimal.
However, I see your point about it being out of scope! Thank you very explaining. 🙂
