LUMEN: Coordinated Failure Recovery for Distributed LLM Serving

Zhang Cao, Shujie Han, Juncheng Zhang +3

Modern large language model (LLM) serving clusters distribute inference requests across multiple worker processes on different GPUs, but failures are prevalent at scale. When a wor…

Leveraging I/O Stalls for Efficient Scheduling in ANNS

Juncheng Zhang, Yuanming Ren, Yongkun Li +1

Disk-based graph indexes for approximate nearest neighbor search (ANNS) must serve latency-sensitive queries and throughput-demanding updates concurrently. We observe that over 40%…
