NCP-AII Question 81
Select 4An organization is deploying an AI workload on an NVIDIA GPU cluster and notices inconsistent performance during training runs. As part of validating the hardware operation, which steps should be performed to ensure the hardware is functioning correctly?
- A
Run NVIDIA System Management Interface (nvidia-smi) to verify GPU utilization and memory usage.
- B
Perform a diagnostic run using NVIDIA Validation Suite (NVVS) or DCGM diagnostic tools.
- C
Ensure that the GPUs are running the latest firmware and compatible driver versions.
- D
Ignore minor temperature fluctuations as they are usually unrelated to hardware issues.
- E
Check the power delivery to each GPU and ensure it meets the recommended specifications.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Validating hardware operation for workloads involves a combination of monitoring, diagnostics, and ensuring compatibility. Using tools like nvidia-smi and NVVS helps identify performance bottlenecks and hardware errors. Checking firmware, drivers, and power delivery ensures the system is running in an optimal and supported configuration. Neglecting temperature fluctuations can lead to missed overheating issues, so they should also be monitored carefully.
- A. Correct.
Using
nvidia-smiis a critical step to check GPU utilization and memory usage, which can indicate hardware health and performance bottlenecks. - B. Correct.
Diagnostic tools like NVIDIA Validation Suite (NVVS) or DCGM diagnostics are designed to detect hardware errors or misconfigurations, making them vital for validation.
- C. Correct.
Ensuring the GPUs are running the latest firmware and drivers is essential for compatibility, stability, and performance.
- D. Incorrect.
While minor temperature fluctuations are normal, ignoring them entirely can lead to undiagnosed overheating issues, which may indicate hardware or cooling system problems.
- E. Correct.
Power delivery issues can cause instability or degraded performance in GPUs, so verifying power supply specifications is crucial during hardware validation.
