Question 910
At the Riverbrook high-performance computing center, a shared GPU node shows high power usage but administrators cannot identify which scheduled project caused the load. Which statement best identifies the control gap?
Explanation
Correct Answer
The situation indicates that fleet-level metrics alone cannot assign resource demand to individual workloads. The recommended response is to correlate device utilization and process accounting with approved scheduler job identifiers, with a follow-up check that a completed test job shows a matching allocation and device-use record for the correct project. This directly addresses the reported issue at the Riverbrook high-performance computing center.
Incorrect Answers
Power policy or supply constraints can affect accelerator clocks and sustained performance. This can occur in other projects, but it is not the primary explanation at the Riverbrook high-performance computing center.
This explanation belongs to gpu virtualization compatibility. The immediate weakness in the question is that fleet-level metrics alone cannot assign resource demand to individual workloads. For the Riverbrook high-performance computing center, the priority is to correlate device utilization and process accounting with approved scheduler job identifiers.
Although without resource usage records teams cannot evaluate real consumption or fair capacity sharing, the situation does not describe that specific cause; it instead indicates that fleet-level metrics alone cannot assign resource demand to individual workloads. For the Riverbrook high-performance computing center, the priority is to correlate device utilization and process accounting with approved scheduler job identifiers.
