Operating Systems Research Group
Operating Systems Research on Energy, Reliability and Autonomy


Research Statement

As rapid advances in computing hardware have led to dramatic improvement in computer performance, the issues of reliability, availability, maintainability, and cost of ownership are becoming increasingly important. The Opera research group conducts research in operating systems with focuses on power management, autonomic computing, and software reliability and availability.

Our research also involves other disciplinary such as architecture, database, data mining and artificial intelligence. Basically, the theme of our research investigate innovative ideas by exploiting the new features of modern architecture, applying database and data mining solutions and machine learning algorithms to improve system performance, robustness, reliability and manageability.
