NCP-AII Question 131
Single answerYou are configuring a system with an NVIDIA A100 GPU to run multiple AI workloads simultaneously. To ensure that each workload has dedicated GPU resources while maximizing GPU utilization, you decide to use Multi-Instance GPU (MIG). After enabling MIG mode on the GPU, what is the correct next step to configure specific GPU instances?
- A
Use the
nvidia-smi mig-configcommand to create and assign GPU instances. - B
Reboot the system to apply the MIG mode changes.
- C
Use the
nvidia-smicommand to partition the GPU into instances and specify their sizes. - D
Install the NVIDIA MIG partitioning software to split GPU resources.
Show answer and explanation
Correct answer: C
Explanation
To configure Multi-Instance GPU (MIG) after enabling MIG mode on a GPU, the correct approach is to use the nvidia-smi command with the appropriate subcommands. This allows users to create GPU instances of varying sizes, ensuring optimal resource allocation for workloads. No external software or system reboot is required.
- A. Incorrect.
This is incorrect because
nvidia-smi mig-configis not a valid command. Whilenvidia-smiis used for configuration, the correct subcommands must be used to partition the GPU. - B. Incorrect.
This is incorrect because enabling MIG mode does not require a system reboot. The changes take effect immediately once MIG is enabled.
- C. Correct.
This is correct because the
nvidia-smicommand includes specific subcommands to configure GPU instances and specify their sizes for MIG-enabled GPUs. - D. Incorrect.
This is incorrect because no additional partitioning software is required. The NVIDIA driver and
nvidia-smiprovide the necessary tools to configure MIG.
