A Cross-Layer Multicore Architecture to Tradeoff Program Accuracy and Resilie…

To protect multicores from soft-error perturbations, resiliency schemes have been developed with high coverage but high power/performance overheads (
2). We observe that not all soft-errors affect program correctness, some soft-errors only affect program accuracy, i.e., the program completes with certain acceptable deviations from soft-error free outcome. Thus, it is practical to improve proce…
