[slurm-users] Limits to partitions for users groups

[Рачко Антон Сергеевич]

I have partition with 35 nodes. Many users use it, but one group of them have 
more priority than others. I want to set limit of max. 20 nodes for any users 
and allow use all nodes for users in priority group.
I can split this partition to 2: 20-node partition for all and 15-node for 
priority group. Can I do it otherwise (sacctmg, QOS, etc.)?
