About Us 

Our Computer Systems and Data Science (CASS) laboratory have primary research interests which cover a wide spectrum in the areas of high-performance computing and storage systems. A common thread among our research projects focuses on fast data access and resource sharing with cost- and energy-efficient management at different levels of memory and storage hierarchies in supercomputer, parallel, and distributed computer systems. More recently, CASS research interests cover the areas of interdisciplinary computing, computer architecture, and low-power computing. A significant complementary thread among CASS’s extensive research projects emphasizes developing new software tools and hardware platforms to stimulate advances in science and engineering research, where large digital data collections are increasingly prevalent. CASS research projects have been sponsored by several federal funding agencies such as the National Science Foundation, the Department of Energy, and NASA.

News

Exciting news! Our research paper “ALISA: Accelerating Large Language Model Inference via Sparsity-Aware KV Caching” has been accepted by the prestigious 51st IEEE/ACM International Symposium on Computer Architecture (ISCA ’24)! 🎉📜
In this work, we propose a novel algorithm-system co-design approach to alleviate the I/O bottlenecks in LLM inference. Our approach employs a Sparse Window Attention (SWA) mechanism that identifies the high-importance tokens for generative inference with low overhead and minimal accuracy drop, as well as a three-phase dynamic scheduling strategy that optimizes the trade-offs between computation and caching.
