NVIDIA NCP-AIO Exam - Topic 1 Question 11 Discussion

Actual exam question for NVIDIA's NCP-AIO exam

Question #: 11
Topic #: 1

You are managing a Slurm cluster with multiple GPU nodes, each equipped with different types of GPUs. Some jobs are being allocated GPUs that should be reserved for other purposes, such as display rendering.

How would you ensure that only the intended GPUs are allocated to jobs?

AVerify that the GPUs are correctly listed in both gres.conf and slurm.conf, and ensure that unconfigured GPUs are excluded.

BUse nvidia-smi to manually assign GPUs to each job before submission.

CReinstall the NVIDIA drivers to ensure proper GPU detection by Slurm.

DIncrease the number of GPUs requested in the job script to avoid using unconfigured GPUs.

Show Suggested Answer

Suggested Answer: A

Comprehensive and Detailed Explanation From Exact Extract:

In Slurm GPU resource management, the gres.conf file defines the available GPUs (generic resources) per node, while slurm.conf configures 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 configuring gres.conf allows Slurm to recognize and expose only those GPUs meant for jobs.

slurm.conf must be aligned to exclude or restrict unconfigured GPUs.

Manual GPU assignment using nvidia-smi is 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 in gres.conf and slurm.conf to restrict job allocations to intended GPUs.
