个人简介

My research focuses on building system infrastructures to systematically bring better performance and resilience to applications. My current focused topics including:

Operating system and distributed system support for AI and AGI. [ParallelGPUOS preprint[DMVectorSearch preprint [BlitzScale OSDI'25](To appear) [KunServe preprint]
The next-generation cloud computing infrastructure (Serverless). Serverless computing is a promising future direction for future cloud computing. However, current systems stacks are not designed for the new paradigm. How can we build the next-generation serverless system? [MITOSIS OSDI'23][DMERGE (To appear)]
The next-generation storage system stack. Storage system (e.g., key-value stores and distributed file systems) are quickly evolving with modern hardwares and modern diverse workloads. How can they compose to better evolve with such trends? My related projects include:

Fast remote persistent memory: Characterizing and Optimizing Remote Persistent Memory with RDMA and NVM [USENIX ATC'21]

System co-design with modern datacenter networking Modern datacenter fast interconnects like RDMA and SmartNIC offer extremely powerful in-networking computing capabilities. How can we fully utilize the power of these networking features? My related projects include:

DrTM: Fast In-memory Transaction Processing using RDMA and HTM [SOSP'15 ACM TOCS EuroSys'16 OSDI'18], Replication-driven Live Reconfiguration [USENIX ATC'17]
DST(Decentralized Scalar Timestamp): Scalable timestamps for efficient MVCC [NSDI'21]

Machine learning for systems. The advances in machine learning (ML) technologies also bring huge optimization space for computer systems. Besides providing powerful heuristics, the ML methods can change the complexity of traditional algorithms (e.g., sorting and indexing). My related projects include:

XStore: Fast RDMA-based Ordered Key-Value Store using Remote Learned Cache [OSDI'20 ACM TOS]
