[slurm-users] Incorrect Number of GPUs?

Hello all,

I have a GPU node with 3 identical GPUs (we started with two and recently
added the third). Running nvidia-smi correctly shows that all three are
recognized. My gres.conf file has only this line:

NodeName=gpu01 File=/dev/nvidia[0-2] Type=quadro_8000 Name=gpu Count=3

And the relevant lines in slurm.conf are:

NodeName=gpu01 Sockets=2 CoresPerSocket=16 ThreadsPerCore=1
RealMemory=189900 State=UNKNOWN Gres=gpu:quadro_8000:3

As far as I can tell, all of this is fine (and we had no issues when we
only had the initial two GPUs in the system). However, now when I run sinfo
-o %G (which as I understand will report the total number of gres resources
available), this is the output:


Is this saying that it doesn't recognize the third card? Any suggestions?
As always, thank you for your help!

Warmest regards,
