[slurm-users] Limit number of allocated GPUs

[Gestió Servidors via slurm-users]

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.
