MADSys
The MADSys (Machine Learning, AI, Big Data Systems) group is dedicated to the design, implementation, evaluation, and application of parallel and distributed systems. Our research spans various methods aimed at accelerating data processing. Although the foundational principles like caching, batching, and overlapping are consistent, the strategic and innovative application of these techniques allows system researchers to optimally utilize diverse hardware resources across different scenarios.

Projects
Essentially, a decoder-only Transformer model transforms data from any modality into KVCache, positioning it as a central element in LLM serving optimizations. These optimizations include, but are not limited to, caching, scheduling, compression, and offloading. KVCache.AI is a collaborative endeavor with leading industry partners such as Approaching.AI and Moonshot AI. The project focuses on developing effective and practical techniques that enrich both academic research and open-source development.
Mooncake is the serving platform for Kimi, a leading LLM service provided by MadSys, Moonshot AI et.al.
A Flexible Framework for Experiencing Cutting-edge LLM Inference Optimizations.
Prompted by advancements in modern interconnect technologies like RDMA and CXL, this project aims to revisit the implementation and application of distributed shared memory (DSM). The objective is to facilitate the development of resilient distributed applications that can tolerate partial failures, making this process as straightforward and efficient as programming concurrent applications on a single machine. RDSM is a collaborative endeavor with leading industry partners such as Alibaba and Intel, dedicated to establishing fundamental frameworks that enhance both academic research and open-source development.
