Dynamic Fault-Tolerance Management and Metrics for Battery Powered Failure-Prone Systems
Abstract
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 non-linearities. This paper introduces the concept of adaptive fault-tolerance 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 evaluation scenario, it is shown that system configurations with the best performance and lifetime are not necessarily those with the best combination of performance, reliability, battery lifetime and average power consumption.
