UnverifiedvLLM's ModelRunner uses the int8 type to allocate untyped byte arrays on a per-byte basis when allocating KV Cache VRAM.71% similarUnverifiedThere is a bug in vLLM when prefix caching and DFlash2 are both enabled, which causes the last cache unit (a mixed-layout block of approximately 16 tokens) to be directly discarded and recomputed.70% similarUnverifiedvLLM uses PagedAttention technology to manage KV Cache, and its memory allocation and request scheduling introduce runtime non-determinism.67% similarUnverifiedvLLM、TensorRT-LLM等LLM推理服务通过KV Cache机制在单次请求内缓存中间注意力计算结果，但该缓存是请求级别的，HTTP连接关闭后即被释放67% similarUnverifiedvLLM employs continuous batching technology to allow requests from different users to be processed in parallel within the same GPU batch, improving throughput while enabling finer memory boundary management between requests.61% similar
