Fault tolerance plays a key role in the design of real-time and multitask parallel computing systems. Aiming at the re-quest of high reliability and efficiency in the real-time and multitask parallel computing system, the basic concepts, basic meth-ods and basic thoughts in the technology of reliability and fault tolerance of computing system are introduced, based on the check-pointing technology and back-out recovery technology. Fault-tolerance parallel computing system from multi-levels and multi-aspects and the solving way of midway message and isolated message are put forward. At the same time, the relate model and technology evaluating are discussed to prove the validity of the model.
