Virtual Pipeline Parallelism Improves Chunked Prefill in Long-Context LLM Inference

Chunked prefill pipeline parallelism (CPP) is important for LLM inference but suffers from latency imbalance due to longer attention on later chunks. Existing dynamic chunk resizing methods reduce this imbalance but increase scheduling overhead, prompting new approaches like Virtual Pipeline Parall...

AI-assisted summary based on the listed source.

Chunked prefill pipeline parallelism (CPP) is a key technique for LLM inference. However, equal-size chunks exhibit imbalanced latency, as later chunks attend longer prefix KV caches and incur higher attention costs, leading to pipeline bubbles. Existing approaches mitigate this imbalance through dynamic chunk...

Efficient chunked prefill reduces pipeline bubbles and improves inference speed in long-context LLMs. Balancing latency without excessive overhead is critical for scalable and responsive LLM deployment.
