针对基于容错的并行计算机系统的高可靠性和高效性的要求，探讨了多机系统中较 难解决的同步策略．从系统上电同步、任务调度同步和表决同步三个方面提出了客错与并行处 理系统的同步方案，并在样机上实现．
Aiming at the requirements of high reliability and high efficiency of fault-tolerant parallel computer system, the synchronization strategy which is hard to be solved in multi-machine system is discussed. The synchronization scheme of fault-tolerant and parallel processing system is put forward from three aspects of system power-on synchronization, task scheduling synchronization and voting synchronization, and implemented in the prototype.
