問題文
A cluster acceptance plan includes a dense linear algebra benchmark. A team member asks why this benchmark is included when the cluster is intended for training workloads rather than for classical simulation. What is the best answer?
選択肢
- It measures the fabric between nodes more thoroughly than a collective communication test does, which is why it validates the network portion.
- In a short window, it is quick enough to run on every server, and the plan can therefore include it without extending the schedule.
- It is the workload the cluster will actually run in production, so a result close to the published figure is the agreed acceptance criterion.
- It drives the accelerators and their memory close to their limits for a sustained period, which exposes power, cooling, and stability problems that short checks miss.
