Zhu and collaborator receive $453k NSF grant




The National Science Foundation has awarded a 3-year $453,708 grant to support Dakai Zhu and Hakan Aydin's collaborative research on "Generalized Reliability-Aware Power Management for Real-Time Embedded Systems". Dr. Zhu is an assistant professor in the Department of Computer Science at the University of Texas at San Antonio, and Dr. Aydin is an associate professor at George Mason University.

Energy efficiency is mandated by the emergence of small foot-print, portable, and battery-powered computers as well as ever-increasing power density that puts stringent constraints even on computers connected to the power grid. Moreover, recent research has revealed that aggressive power management techniques can significantly increase vulnerabilities of computer systems to transient faults (soft errors) that can cause incorrect operations at run-time. These problems are even more pronounced for real-time embedded systems that must perform correctly at high reliability levels, under strict timing and energy constraints. Although a number of pioneering reliability-aware power management schemes have been proposed that aim at mitigating the negative effects of the popular dynamic voltage and frequency scaling. In this project, the PIs will address the conservatism of the existing solutions and develop amore general framework. Specifically, novel solutions will be devised to achieve arbitrary reliability levels through the use of shared recovery tasks. In addition, the PIs will extend the framework to multiprocessor and emerging multicore platforms.
