NCA-AIIO Question 94
Select 3An AI data center administrator notices inconsistent GPU utilization across multiple nodes in a cluster running AI workloads. Which of the following steps are essential for diagnosing and resolving the issue?
- A
Monitor GPU utilization metrics using tools like NVIDIA DCGM (Data Center GPU Manager).
- B
Analyze workload distribution and scheduling policies within the cluster.
- C
Increase the power limit of all GPUs in the cluster to ensure maximum performance.
- D
Review thermal and cooling data to check for potential throttling issues.
- E
Reinstall the NVIDIA GPU drivers on all nodes without further analysis.
Show answer and explanation
Correct answers: A, B, D
Explanation
Diagnosing inconsistent GPU utilization requires a systematic approach that involves monitoring metrics, analyzing workload distribution, and reviewing environmental factors like cooling. Tools like NVIDIA DCGM are essential for real-time monitoring, while analyzing workloads and thermal data helps pinpoint the root cause of the issue. Arbitrary actions like increasing power limits or reinstalling drivers should be avoided without proper diagnostics.
- A. Correct.
Monitoring GPU utilization metrics with tools like NVIDIA DCGM provides critical insights into how GPUs are being used and helps identify anomalies or bottlenecks.
- B. Correct.
Analyzing workload distribution and scheduling policies ensures that the workloads are evenly and optimally distributed, preventing underutilization or overloading of GPUs.
- C. Incorrect.
Increasing the power limit without understanding the root cause of the issue can lead to unnecessary energy consumption and hardware damage without resolving the problem.
- D. Correct.
Thermal and cooling data is crucial for identifying potential throttling caused by overheating, which can affect GPU performance.
- E. Incorrect.
Reinstalling GPU drivers without diagnosing the issue is not a recommended first step and can lead to unnecessary downtime without ensuring the resolution of the problem.
