Slurm is reserving a GPU node even if I exclude it

Hi,

@baptiste.coudray

sinfo output: shared-gpu up 12:00:00 1 down* gpu005

This is informative only, this doesn’t mean that gpu005 will be assigned.

@baptiste.coudray

So, I tried to exclude it but it didn’t work.

No need to explicitly exclude it. As you are requesting ampere cards, this node won’t be picked up by slurm.

@baptiste.coudray

squeue output: (ReqNodeNotAvail, UnavailableNodes:gpu[004-006,020])

gpu004-006 mean gpu004, 005, 006 right ?

You get this output because Slurm is listing all the nodes that aren’t available in the requested partition. The filter isn’t on the gpu type that will be used by slurm later. As I said, this is informative only, everything is correct. And yes, in the message gpu005 is included.
