Fault-Tolerant Rate-Monotonic First-Fit Scheduling in Hard-Real-Time Systems

Abstract

ÐHard-real-time systems require predictable performance despite the occurrence of failures. In this paper, fault tolerance is implemented by using a novel duplication technique where each task scheduled on a processor has either an active backup copy or a passive backup copy scheduled on a different processor. An active copy is always executed, while a… (More)
