| 摘 要： | 为了解决传统仲裁机制故障覆盖率和故障诊断成功率低的问题,针对容错计算机,提出了一种基于仲裁处理器的仲裁机制,并设计了仲裁系统和仲裁算法.其中仲裁处理器使用三模冗余系统和芯片级的容错设计技术,仲裁算法采用分级方式,同时采用自检测和心跳监测相结合的故障监测机制,有效地解决了单点故障和检测成功率低的问题.最后通过故障注入方式验证了仲裁系统的可用性.

| Abstract: | To greatly reduce detection costs and effectively improve scalability of system,this paper proposed an arbitration system and arbitration algorithm based on arbitration processor.Arbitration processor used TMR system and the chip level fault-tolerant design technology to improve reliability.Arbitration algorithm used hierarchical mode,which could effectively reduce the arbitration overhead.With the detection and heartbeat detection,improved the fault coverage rate and the successful failure detection rate.L... |
