Performance Evaluation of a Parallel System Processing Fault-Tolerant Programs,
Kim,K H, Jenson,M J · Defense Technical Information Center (DTIC) · 1977
A parallel (multiprocessor) system processing fault-tolerant programs was previously developed. The system performance is evaluated in this paper, using an analytic approach based on stochastic models. The analysis confirms the high effectiveness of a parallel system, under all practical circumstances, in reducing the program execution time increase due to run-time validation and system state saving. It also shows how the system performance is affected by various program characteristics.
