Cyber-Physical Systems is a new frontier of research for computer science and engineering. It has been highlighted by the recent August 2007 President's Council of Advisors on Science and Technology (PCAST) report and recommended by the Federal Networking and Information Technology R&D (NITRD) as a top priority for federal research investments. How to provide performance guarantees for Cyber-Physical Systems is an important research problem. In this talk, Liu will present some of his recent work on achieving temporal performance guarantees for cyber-physical systems, exemplified by large scale Internet Data Centers and real-time embedded systems. First, he will show how we can use feedback-control-based resource allocation schemes to control the response time of Internet Data Centers. Then he will present Universal Feasible Region Analysis, which is a new schedulability analysis framework for ensuring response time guarantee for networked embedded systems under general workload.
Liu is an associate professor of computer science and engineering, and a College of Engineering Distinguished Scholar at the University of Nebraska-Lincoln. From 2007 to 2009, he was an assistant professor in the School of Computer Science at McGill University, Canada. He was also affiliated to the Department of ECE, Centre for Intelligent Machines (CIM), and Centre for Advanced Systems & Technologies in Communications (SYTACom) at McGill. He obtained his Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 2006. He obtained his B.S. degree in Mathematics and M.S. degree in Automatic Control both from Tsinghua University, China. His research interests are in Cyber-Physical Systems, real-time and embedded systems, server and data centers, and software reliability. He worked briefly in the Hewlett-Packard Labs and IBM T. J. Watson Research Center. He received the NSERC Discovery Grant Award in 2007 and the IEEE Transactions on Industrial Informatics Best Paper Award in 2008. He also received the Ray Ozzie Fellowship, the Saburo Muroga Fellowship, the Mavis Memorial Fund Award, and the C. W. Gear Outstanding Graduate Award, all from the University of Illinois at Urbana-Champaign. He has filed five patents, and published more than 80 research papers in international journals and major peer-reviewed conference proceedings.
