Xianwei completed his Phd in the Computer Science Department at University of Pittsburgh. During 2013-2017, he was working on computer architecture and systems under the supervision of Prof. Youtao Zhang, Prof. Bruce Childers and Prof. Jun Yang. Before joining Pitt, Xianwei obtained his Bachelor's degree (2011) on Software Engineering from Northwestern Polytechnical University (NPU). More info can be found in LinkedIn.
Topics: Memory System, GPU, Computer Architecture and Systems
Xianwei's research interests lie broadly in hardware and software co-designs to improve the performance and energy efficiency of computing systems. A particular emphasis is on memory system and GPU design around the critical aspects of latency, energy and bandwidth, etc.
