Exam NCP-AII Topic 1 Question 270 Discussion

Actual exam question for NVIDIA's NCP-AII exam
Question #: 270
Topic #: 1
You are managing an NVIDIA DGX A100 server and notice that GPU utilization fluctuates significantly during a supposedly constant training workload. You suspect power capping might be the cause. How can you definitively determine if power capping is active and affecting GPU performance?

Suggested Answer: C Vote an answer

The most direct way to determine if power capping is active is to use 'nvidia-smi' and query the 'ClocksThrottleReasonS. If PowerCap' is listed as active, it definitively indicates that power capping is in effect and limiting the GPU's performance. The 'pstate' value can be indicative, but not always conclusive. Temperature alone doesn't confirm power capping.
