Question 830
At the Fairhaven retail recommendation platform, two training users launch jobs directly on a shared node and each assumes exclusive access to all GPUs. Which technical or process problem best explains the failure?
Explanation
Correct Answer
This explanation matches the reported facts: uncoordinated device use can oversubscribe hardware and undermine accounting or job reliability. A corrective test should establish that concurrent test jobs receive permitted nonconflicting allocations and accurate queue state. This directly addresses the reported issue at the Fairhaven retail recommendation platform.
Incorrect Answers
That statement concerns multi-tenant namespace quotas; here the reported facts point to a different issue: uncoordinated device use can oversubscribe hardware and undermine accounting or job reliability. For the Fairhaven retail recommendation platform, the priority is to use Slurm or another governed batch scheduler with explicit GPU resource allocation.
Shared compute resources can introduce performance contention even when access isolation is correct. This can occur in other projects, but it is not the primary explanation at the Fairhaven retail recommendation platform.
Although a workload can be constrained by device memory bandwidth rather than arithmetic capacity, the situation does not describe that specific cause; it instead indicates that uncoordinated device use can oversubscribe hardware and undermine accounting or job reliability. For the Fairhaven retail recommendation platform, the priority is to use Slurm or another governed batch scheduler with explicit GPU resource allocation.
