[slurm-users] Slurm 25.05: Retrieving jobs GPU Indices on Heterogeneous Cluster

Hello,

I'm running Slurm 25.05 on a heterogeneous cluster (several kind of GPU in the same node) with AutoDetect=nvml and shared mode. When submitting a job with `#SBATCH --gres=gpu:1`, CUDA_VISIBLE_DEVICES is correctly set to a single and valid free GPU index but `scontrol show jobid` does not report any detail about GPU allocation.

How can I retrieve the GPU indices assigned to running jobs (reflecting CUDA_VISIBLE_DEVICES) in shared mode? Is there a Slurm command or configuration to enable tracking of these indices on a heterogeneous cluster?

The goal is to help automatic choice of the free and appropriate gpu according to the job's needs in order to save bigger gpus for bigger jobs at the time of submitting.

Thanks
