Hello, We have a recurring demand where some users would like to use idle GPU resources on periods where the usage is low. Their normal GPU/qos limits prevent this, which is expected as part of the fair share scheduler principles. A pattern we're considering is the preempt option on slurm to have these jobs being pre-empted when another user is submitting his jobs within his quota. The jobs that were submitted earlier by a faculty member taking advantage of available resources on top of his regular qos, will be preempted however, there is no suspend option for gpu jobs. There is only requeue, which kills the jobs to make the gpu available. I believe you can use suspend for cpu/mem without killing the job. I know that would require the users to set up checkpoints and re-start their jobs. The goal is to let heavy users fill otherwise idle nodes over low usage time without impacting smaller users when activity picks up. Has anyone implemented something similar? I am in general against preemption because that might lead to conflict between users. Thanks, *Fritz Ratnasamy*Data Scientist Information Technology
