I need your help. I have a user who is able to bypass his account Limit, 
and I can't figure out why.

We have two partitions with lower tier (all hosts) named "long", and 
higher tier (only one host) named "sfglab". Here is it's config:

PartitionName=long Nodes=dgx-[1-4],sr-[1-3] MaxTime=10-0 State=UP 
PriorityTier=10000 QOS=long OverSubscribe=NO DefaultTime=2-00:00:00 
PreemptMode=suspend TRESBillingWeights=CPU=1,Mem=0.062G,GRES/gpu=72.458

PartitionName=sfglab Nodes=dgx-1 MaxTime=10-0 State=UP 
PriorityTier=20000 PreemptMode=off OverSubscribe=NO AllowAccounts=sfglab 
AllowGroups=sfglab TRESBillingWeights=CPU=1,Mem=0.062G,GRES/gpu=72.458 

Partition long also has assigned QOS (named "long") with limit: 

And also we have account (also named "sfglab") with limits:

sacctmgr modify account where name=sfglab set 

As a result user is able to allocate more 32 GPUs...
I don't understand why :(

We use slurm 23.02.2.

best regards | pozdrawiam serdecznie
