A large language model inference system is processing two user requests concurrently. Request 1 has a very long initial prompt that requires significant initial computation. Request 2 is already in the process of generating a response, producing one token at a time. The system's scheduler operates by breaking the initial computation for Request 1 into three smaller chunks. It processes the first chunk of Request 1, then generates one token for Request 2, then processes the second chunk of Reques

An LLM inference system is handling two sequences simultaneously using iteration-level scheduling with chunked prefilling. Sequence A has a long prompt that is broken into three prefill chunks (P₁, P₂, P₃). Sequence B is already in the middle of generating its response, requiring individual decode steps (D₁, D₂, D₃). Arrange the following computational steps into the most efficient order that demonstrates this scheduling strategy, ensuring that neither sequence is unnecessarily blocked.
