Hello,

I would like to know if it would be possible to limit, using "sacctmgr", use of a certain type of GPU according the name I have assigned in "gres.conf" file. For example, my small cluster has 3 GPUs nodes sharing 2 GPUs each one. Two of that GPUs are the same model but they are located in different servers. Because of my scenario, I would like to limit users to user only one of that GPU type and not allowing to use both of them.

For example:

* gpu-node-1: * GTX1080 * RTX3080 * gpu-node-2: * GTX750 * GTX680 * gpu-node-3: * RTX2070 * RTX3080

What I want is users could user all of them but simultaniously, a user only could use one of the RTX3080.

Using QoS I have created a new "qos" with "sacctmgr add qos test-gpu-limit MaxTRESPerUser=gres/gpu=1", but with this new QoS, users are limited to use only one GPU, even they need to use different GPUs models. I have tried with "sacctmgr add qos test-gpu-limit MaxTRESPerUser=gres/gpu:RTX3080:1" but system returns this error "sacctmgr: error: slurmdb_format_tres_str: no TRES id found for gres/gpu:RTX3080:1".

So, could be possible to apply limits I want to apply?

Thanks.
