Analysis and randomized design of algorithm-based fault tolerant multiprocessor systems under an extended model

Reliability of compute-intensive applications can be improved by introducing fault tolerance into the system. Algorithm based fault tolerance (ABFT) is a low-cost scheme which provides the required fault tolerance to the system through system level encoding. In this paper, we propose randomized construction techniques, under an extended model, for the design of ABFT systems with the required fault tolerance capability. The model considers failures in the processors performing the checking operations.
