TMR容错计算故障恢复技术研究

Research on Fault Recovery Techniques for TMR Fault-tolerant Computing

提出了一种可伸缩的TMR容错计算系统结构,根据TMR系统出现故障的情况,详细研究了其故障恢复模型和恢复策略。通过综合采用向前和向后恢复方法有效减少了由于实现容错功能而对系统运行进程完成时间的推延并进行了定量分析和验证。

The system architecture of a kind of scalable fault-tolerant computer with triple module redundancy is pro- posed. Detailed study on its fault recovery model and scheme corresponding to different fault occurrence situations is done. Through synthetically adopting forward recovery and roll-back recovery, the impact on the completion time delay of system processes due to the demand on fault tolerance can be efficiently cut down, which is quantitatively analyzed and validated.
