Distributed System Research Group at NCSU (Overview of Dr. Gu's research)
Presenter: Helen Gu
Abstract
Distributed systems have become the fundamental computing infrastructure for many important real-world applications such as grid computing, peer-to-peer system, enterprise data center, online data analytics, Web search engine, and emerging cloud computing platform. Our research is focused on automatic management of complex large-scale distributed systems such as distributed virtual computing infrastructure, massive data stream processing, service overlay networks, and peer-to-peer systems. In particular, our research group studies several aspects of automatic system management including system resource management, system heath management, and secure service provisioning. In this talk, I will introduce several on-going projects addressing those issues: i) The InfoEye project aims at providing a scalable information management service that can resolve dynamic information queries issued by system administrators or other system management controllers; ii) The ALERT project aims at providing online anomaly prediction capabilities to raise alerts for impending system health problems; and iii) The SysMD project aims at providing automatic online system diagnosis to discover possible anomaly causes and suggest proper anomaly mitigation actions. We will apply our techniques on several large-scale distributed system infrastructures such as PlanetLab, VCL, and distributed data stream processing systems.
Short bio
Dr. Xiaohui (Helen) Gu is an assistant professor in the Department of Computer Science at the North Carolina State University. She received a PhD degree in 2004 and a MS degree in 2001 from the Department of Computer Science, University of Illinois at Urbana-Champaign. She received a BS degree in computer science from Peking University, Beijing, China in 1999. She was a research staff member at IBM T. J. Watson Research Center, Hawthorne, New York, between 2004 and 2007, working on the System S Distributed Stream Processing project. Dr. Gu received ILLIAC fellowship, David J. Kuck Best Master Thesis Award, and Saburo Muroga Fellowship from University of Illinois at Urbana-Champaign. She also received the IBM Invention Achievement Awards in 2004, 2006, and 2007. Her research interests are distributed systems with a current focus on intelligent system management (aka autonomic computing), system reliability, system Security, massive data processing system, and peer-to-peer/service overlay networks. She is looking for PhD students to join her research group.
