interactive srun with gpu unsupported by configured SelectType plugin

[tk...@ucdavis.edu]

Hi,

I used a standard slurm-gcp setup with a GPU, I can run GPU based sbatch calls (#SBATCH --gres=gpu:1) and nvidia-smi runs fine, but I am unable to use an interactive session with a GPU. Is there any remedy to that error below?

[cluster-login0]$ srun  --gpus 1 --pty bash

srun: error: Unable to allocate resources: Requested GRES option unsupported by configured SelectType plugin

[cluster-login0]$ srun   --pty bash

[cluster-compute-0-0]$ 

Thanks

Tobias

Hi,

Which gres value do you request?  You need to add a "--gres..." with something that matches a value from your SLURM gres.conf

Regards,

Alex

Hi Alex,

right, I think it was because of the missing gres option, also

adding --gpus will lead to the same issue. Simply the gres option alone

will solve the issue and allow for an interactive GPU run.

[cluster-login0 ~]$ srun --pty  --gres=gpu:1 bash

[cluster-compute-0-0 ~]$ nvidia-smi
