2667 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

A GPU platform has a few very large jobs competing with thousands of small ones. How should scheduling fairness, fragmentation, bin packing, preemption, queueing and starvation shape the architecture?

A compute platform schedules GPU jobs with execution times ranging from minutes to weeks, where large jobs need many co-located accelerators. What happens if the scheduler uses simple first-come-first-served with best-fit packing?

A device-testing platform receives a burst of tens of thousands of test sessions after a major framework release. How should queues, worker pools, concurrency limits, resource classes, scheduling fairness and backpressure prevent capacity exhaustion?
