Comprehensive and Detailed Explanation From Exact Extract:
In Slurm GPU resource management, thegres.conffile defines the available GPUs (generic resources) per node, whileslurm.confconfigures the cluster-wide GPU scheduling policies. To prevent jobs from using GPUs reserved for other purposes (e.g., display rendering GPUs), administrators must ensure that only the GPUs intended for compute workloads are listed in these configuration files.
* Properly configuringgres.confallows Slurm to recognize and expose only those GPUs meant for jobs.
* slurm.confmust be aligned to exclude or restrict unconfigured GPUs.
* Manual GPU assignment usingnvidia-smiis not scalable or integrated with Slurm scheduling.
* Reinstalling drivers or increasing GPU requests does not solve resource exclusion.
Thus, the correct approach is to verify and configure GPU listings accurately ingres.confandslurm.confto restrict job allocations to intended GPUs.
