Abstract

Many real-time systems employed in defense, space, and consumer applications have power constraints and high reliability requirements. In this paper, we focus on the relationship between fault tolerance techniques and energy consumption. In particular, we establish the energy efficiency of Application Level Fault Tolerance (ALFT) over other software-based fault tolerance methods. We then develop sensible energy-aware heuristics for ALFT schemes. The heuristics yield up to 40% energy savings.
