  • Abstract
    Increased complexity of computer architectures, consideration of power constraints, and expected failure rates of hardware components make the design and analysis of energy-efficient fault-tolerance schemes an increasingly challenging and important task. We develop run-time and study FTI, a multilevel checkpoint library, on an IBM Blue Gene/Q. We show that FTI has a low energy footprint and that, consequently optimal checkpoint-interval values with respect to time and energy are similar.
