Since any transient fault can only affect one group of cores, through comparing the results of the corresponding instructions on the two groups, RepTFD can detect malignant transient faults with 100% coverage (here we say that a transient fault is malignant if it leads to an incorrect instruction result).
RepTFD: Replay Based Transient Fault Detection
Fault coverage: For parallel workloads, we propose the first core-level transient fault detection scheme with 100% coverage, i.e., any malignant transient fault that cause an error in the result of an instruction can be detected.
