SPORK: Self-Speculative Forking to Accelerate Agentic LLM Inference
Huajun Bai, Weiwei Lv, Huichuan Zheng +2
LLM agents are becoming a common interface for research, coding, and question answering, yet their Thought-Action-Observation loop is often serial: the model reasons, emits a tool…
PipeANN-Filter: An Efficient Filtered Vector Search System on SSD
Hao Guo, Jiwu Shu, Youyou Lu
We propose PipeANN-Filter, an efficient filtered vector search system on SSD. Unlike existing systems that explore only valid vectors (i.e., those satisfying the attribute constrai…
Efficient Training on Multiple Consumer GPUs with RoundPipe
Yibin Luo, Shiwei Gao, Huichuan Zheng +2
Fine-tuning Large Language Models (LLMs) on consumer-grade GPUs is highly cost-effective, yet constrained by limited GPU memory and slow PCIe interconnects. Pipeline parallelism co…
SwitchDelta: Asynchronous Metadata Updating for Distributed Storage with In-Network Data Visibility
Junru Li, Qing Wang, Zhe Yang +3
Distributed storage systems typically maintain strong consistency between data nodes and metadata nodes by adopting ordered writes: 1) first installing data; 2) then updating metad…
Replicating Persistent Memory Key-Value Stores with Efficient RDMA Abstraction
Qing Wang, Youyou Lu, Jing Wang +1
Combining persistent memory (PM) with RDMA is a promising approach to performant replicated distributed key-value stores (KVSs). However, existing replication approaches do not wor…
Sherman: A Write-Optimized Distributed B+Tree Index on Disaggregated Memory
Qing Wang, Youyou Lu, Jiwu Shu
Memory disaggregation architecture physically separates CPU and memory into independent components, which are connected via high-speed RDMA networks, greatly improving resource uti…
Revisiting Swapping in User-space with Lightweight Threading
Kan Zhong, Wenlin Cui, Youyou Lu +5
Memory-intensive applications, such as in-memory databases, caching systems and key-value stores, are increasingly demanding larger main memory to fit their working sets. Conventio…
Sapphire: Automatic Configuration Recommendation for Distributed Storage Systems
Wenhao Lyu, Youyou Lu, Jiwu Shu +1
Modern distributed storage systems come with aplethora of configurable parameters that controlmodule behavior and affect system performance. Default settings provided by developers…
Kernel/User-level Collaborative Persistent Memory File System with Efficiency and Protection
Youmin Chen, Youyou Lu, Bohong Zhu +1
Emerging high performance non-volatile memories recall the importance of efficient file system design. To avoid the virtual file system (VFS) and syscall overhead as in these kerne…
Improving the Performance and Endurance of Persistent Memory with Loose-Ordering Consistency
Youyou Lu, Jiwu Shu, Long Sun +1
Persistent memory provides high-performance data persistence at main memory. Memory writes need to be performed in strict order to satisfy storage consistency requirements and enab…
