That’s the first limit I placed on our cluster, and it has generally worked out well (never used a job limit). A single account can get 1000 CPU-days in whatever distribution they want. I’ve just added a root-only ‘expedited’ QOS for times when the cluster is mostly idle, but a few users have jobs that run past the TRES limit. But I really like the idea of a preemptable QOS that the users can put their extra jobs into on their own.
