Dynamic Fault-Tolerance and Metrics for Battery Powered, Failure-Prone Systems

Emerging VLSI technologies and platforms are giving rise to systems with inherently high potential for runtime failure. Such failures range from intermittent electrical and mechanical failures at the system level, to device failures at the chip level. Techniques to provide reliable computation in the presence of failures must do so while maintaining high performance, with an eye toward energy efficiency. When possible, they should maximize battery lifetime in the face of battery discharge nonlinearities. This paper introduces the concept of adaptive faulttolerance management for failure-prone systems, and a classification of local algorithms for achieving system-wide reliability. In order to judge the efficacy of the proposed algorithms for dynamic fault-tolerance management, a set of metrics, for characterizing system behavior in terms of energy efficiency, reliability, computation performance and battery lifetime, is presented. For an example platform employed in a realistic eva...
