Abstract :
A proposed lightweight, soft-error-resilient architecture for shared-memory multicores enables cores to autonomously perform redundant execution of uninterrupted instruction sequences. The distributed redundancy control mechanism operates in concert with the coherence protocol to provide resiliency for both computation and communication hardware. The Web extra at http://youtu.be/9A3oiIerI0w is a video interview in which guest editor Srinivas Devadas and author Omer Khan expand on how a proposed lightweight, soft-error-resilient architecture for shared-memory multicores enables cores to autonomously perform redundant execution of uninterrupted instruction sequences.
