Explain dynamic batching in inference servers and its trade-off
WHAT IT TESTS: Inference scheduling and the latency-vs-throughput trade-off. ANSWER OUTLINE: Dynamic batching launches when a time window or max size is met, improving throughput over static batching, but short ones wait for the slowest.
WHAT IT TESTS: Your grasp of inference scheduling and the tension between GPU utilization and request latency. ANSWER OUTLINE: Explain that dynamic batching collects requests until a time window expires or a max batch size is reached, then launches them together; this avoids indefinite waiting and raises throughput, but the trade-off is that every request is still blocked until the longest generation in that batch finishes, so tail latency remains. RED FLAG: Calling it continuous batching or asserting it solves head-of-line blocking.
