Abstract

This chapter takes up a high-reliability computing system with redundancy techniques and recovery methods to prevent failure occurrences. We adopt duplex and majority decision modular systems as redundancy techniques, and apply them to two checkpoint schemes in which their respective interval times are periodic and random. Introducing overheads for recovery and checkpoint, we obtain the mean execution times until the process succeeds, and derive optimal checkpoint times to minimize them. Furthermore, we compare a duplex system and a majority decision system, and discuss analytically and numerically which system is better.
