Thank you for your answer. To test it I tried: sacctmgr update qos normal set maxtresperuser=cpu=2 # Then in slurm.conf PartitionName=test […] qos=normal
But then if I submit several 1-cpu jobs only two start and the others stay pending, even though I have several nodes available. So it seems that MaxTRESPerUser is a QoS-wide limit, and doesn't limit TRES per user and per node but rather per user and QoS (or rather partition since I applied the QoS on the partition). Did I miss something?

On that same page, you'll find MaxTRESPerUser, as a QOS parameter. You can create a QOS with the restrictions you'd like, and then in the partition definition, you give it that QOS. The QOS will then apply its restrictions to any jobs that use that partition.

For example, we would like to limit the total memory allocation of jobs from a user to 200G per node. There is MaxTRESperNode ( [ https://slurm.schedmd.com/sacctmgr.html#OPT_MaxTRESPerNode | https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fslurm.schedmd.com%2Fsacctmgr.html%23OPT_MaxTRESPerNode&data=05%7C02%7Crug262%40psu.edu%7Ca5ac74d119fb4b1e2a6a08dcdc9d71f4%7C7cf48d453ddb4389a9c1c115526eb52e%7C0%7C0%7C638627815993703402%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=ovXl4if01XtEDBQy3GxOG%2BrpH1GiDYFEOjNtz7gpkUs%3D&reserved=0 ] ), but unfortunately, this is a per-job limit, not per user. Ideally, we would like to apply this limit on partitions and/or QoS. Does anyone know if this is possible and how to achieve it?
