随着越来越多的多处理机进入市场和应用，系统可靠性成为多处理机系统的关键问题。由于多处理机系统固有的冗余特性，提高系统可靠性的途径主要是软件策略而不是硬件冗余。针对多处理机系统的容错问题，提出了一种提高系统可靠性的容错策略，该策略利用了操作系统中一种常见的自调度算法（Self-Scheduling，SS）。仿真结果表明了该容错策略的可行性。
With more and more multiprocessor computers coming to the market and applications, system reliability is becoming a key issue of multiprocessor systems. As there is an inherent characteristic of redundancy existing in multiprocessor systems, the way to increase the reliability is aimed at software strategy rather than hardware redundancy. Aiming at realizing fault tolerance and making better utilization of system resources, this paper presents a fault tolerant strategy to increase reliability for multiprocessor systems, which utilizes a common class of operating system algorithm referred to as Self-Scheduling (SS). Simulation results have been analyzed to show the feasibility of the proposed fault tolerant policy.
