You have the right idea.

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.

Subject: [slurm-users] Max TRES per user and node
 
Hello,

We are looking for a method to limit the TRES used by each user on a per-node basis. For example, we would like to limit the total memory allocation of jobs from a user to 200G per node.

There is 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?

Thank you,
