SieveIVF: Threshold-Aware IVF Execution for Large-Scale Training Data Deduplication
Zhisheng Hu, Zhifang Li, Junjie Chen +6
Embedding-based training data deduplication retrieves candidate duplicate edges above an application similarity threshold, but fixed-probe inverted-file (IVF) search ignores this p…
DMG: A Scalable and Efficient Memory-Disaggregated Graph Processing System
Yizou Chen, Tsun-Yu Yang, Zhisheng Hu +2
Traditional graph processing systems are built on monolithic servers, which couple a fixed ratio of compute and memory resources but often result in resource under-utilization in d…
FlexKV: Flexible Index Offloading for Memory-Disaggregated Key-Value Store
Zhisheng Hu, Jiacheng Shen, Ming-Chang Yang
Disaggregated memory (DM) is a promising data center architecture that decouples CPU and memory into independent resource pools to improve resource utilization. Building on DM, mem…
Lotus: Optimizing Disaggregated Transactions with Disaggregated Locks
Zhisheng Hu, Pengfei Zuo, Junliang Hu +3
Disaggregated memory (DM) separates compute and memory resources, allowing flexible scaling to achieve high resource utilization. To ensure atomic and consistent data access on DM,…
