Please read the description of the slurm fairshare algorithm, which is explained in more detail at https://slurm.schedmd.com/priority_multifactor.html#fairshare Fair tree (which we also use and are pretty happy with) is a modification of the above basic fairshare algorithm that works "better" when you have a hierarchy of accounts. The hierarchy might or might not be relevant for your setup, but the basic fairshare idea seems to be exactly what you're asking for, if I understand you correctly. -- Janne Blomqvist, D.Sc.
