Shirley125	b4233a2ec3	[Bugfix] Route requests requiring KVC recomputation from the decode instance to the P instance (#3448) ... ### What this PR does / why we need it? This PR is aimed to fix the recomputing out of memory bug in decode instance. When recomputing happens in decode, kv cache usage may exceed the pre-allocated memory, and it will cause OOM. So we propose a new scheduling strategy, when decode instance cannot allocate new block for running requests, we will stop the request that will be preempted. These stopped request will be recognied by proxy, and they will be send to prefill instance again to calculate kvc and then direct to decode instance. This is a temporary plan to fix the bug. The long-term stratege is to use CPU offload in decode instance. ### Does this PR introduce _any_ user-facing change? An extra ascend configuration option **-- recompute_scheduler_enable = True** is added to enable this strategy. The default value is False ### How was this patch tested? - vLLM version: v0.11.0rc3 - vLLM main: https://github.com/vllm-project/vllm/commit/v0.11.0 --------- Signed-off-by: CHEN <116010019@link.cuhk.edu.cn>	2025-10-18 15:56:44 +08:00
