Question 650
During a regulated deployment assessment at a healthcare imaging provider, engineers report the following issue: A training service shows high GPU activity but throughput falls when power limiting begins. The affected work supports clinical imaging and model-assisted workflows; patient data constraints and reliable model performance are important. Which TWO responses form the best remediation-and-evidence pair? (Select TWO.)
Explanation
Correct Answers
Correct corrective action. Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution. This fits the specific reported issue: A training service shows high GPU activity but throughput falls when power limiting begins. The corresponding failure being reduced is: High memory allocation does not necessarily mean high compute throughput, and thermal or power limits can constrain performance.
Correct independent evidence. A time-series review connects kernel activity and memory use to actual completed training or inference work while checking limit events. This verifies the corrective approach for the affected clinical imaging and model-assisted workflows instead of treating an architecture diagram alone as success.
Incorrect Answers
Not the most direct the action-and-evidence pair for these facts. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity. This choice concerns nvidia mig hardware partitioning and isolation and may be valid in another design. But this case reports 'A training service shows high GPU activity but throughput falls when power limiting begins', which calls for reasoning about gpu utilization memory and power telemetry interpretation. The targeted response is: Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution.
Not the most direct the action-and-evidence pair for these facts. Use a workload scheduler such as Slurm with explicit job GPU resource requests, queue policies and fair-share controls for shared training clusters. This choice concerns slurm batch queues fair-share and reservations and may be valid in another design. But this case reports 'A training service shows high GPU activity but throughput falls when power limiting begins', which calls for reasoning about gpu utilization memory and power telemetry interpretation. The targeted response is: Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution.
Not the most direct the action-and-evidence pair for these facts. Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement. This choice concerns gpu reliability events and diagnostic triage and may be valid in another design. But this case reports 'A training service shows high GPU activity but throughput falls when power limiting begins', which calls for reasoning about gpu utilization memory and power telemetry interpretation. The targeted response is: Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution.
