> About

Hi there! I'm Xianwei, now an Associate Professor (2020 - ) in School of Computer Science & Engineering at Sun Yat-sen University, researching on computer architecture and system towards high-performance and intelligent computing.

During 2017-2020, I worked in AMD Inc. (Research & RTG) on architecture and software designs for compute-optimized GPUs. Previously, I completed my Ph.D. (2017) in the Computer Science Department at University of Pittsburgh, and obtained Bachelor's (2011) degree on Software Engineering from Northwestern Polytechnical University.

More info can be found in LinkedIn.

> Research

Topics: GPU, Compiling, Memory System, HPC, Intelligent Computing, Simulation/Modeling/Profiling
Grants: National Key R&D Program, NSFC Program, CCF-Tencent®/Huawei®/Phytium® Funds

My research interests lie broadly in hardware and software co-designs to improve the performance and efficiency of computing systems. A particular emphasis is on GPU computing and memory system design through architecture/compiler/runtime around the critical aspects of latency, energy and bandwidth, etc.

I currently lead the arcSYSu (ARChitecture and SYStem Upscaling @ SYSU) research team, and fortunately work with a group of wonderful graduate and undergraduate researchers/interns on computing systems.

[⭐️ Hiring!] Welcome to join us! [详见 Q&A]
