You may want to look at MaxTRESPerNode and possibly MaxTRESPerJob. Doing it PerUser means all running jobs for that user, which may not be what you want.

Hello,

 

I have three nodes, serving each one 2 GPUs. I would like to limit (qos??) that a user could user only one GPU from earch server, but user could user simultaneously three GPUs if each GPU belongs to different servers. With this QoS “sacctmgr add qos test-limit-GPUs MaxJobsPerUser=3 MaxTRESPerUser=gres/gpu=1” I can limit to one GPU, but then user can’t run other job in a GPU from other server. How must I configure QoS (or other method) to allow more than one job requesting GPUs but never in the same server?

 

Thanks.
