Hello,

Issue 1:

I am using slurm version 24.05.1 , my slurmd has a single node where I connect multiple gres by enabling the overscribe feature.

I am able to use the advance reservation of gres only using gres name (tres=gres/gpu:SYSTEM12).

i.e while in reservation period , if other users submits job with SYSTEM12 , then slurm places this job in queue 

user1@host$ srun --gres=gpu:SYSTEM12:1 hostname

srun: job 333 queued and waiting for resources     

but when other users just submit a job without any system  name , slurm jobs goes through on that gres immediately even though it is reserved.

user1@host$ srun --gres=gpu:1 hostname                                                        

mylinux.wbi.com                                                                                         

Also I can see GresUsed in busy mode using "scontrol show node -d"   , this means the job is running on Gres/GPU and not on cpu etc.                                                                                                               

Same way , job submission based on Feature "rev1 in my case" is also going through even though it is reserved for other users in multiple partition slurm.

Issue 2:

while execution , Slurm o/p's some extra prints in the srun output

user1@host$ srun --gres=gpu:1 hostname                                                                                                                                                                                      

srun: error: extract_net_cred: net_cred not provided
