多进程系统状态恢复的一种优化方法

A New State Recovery Approach in Distributed System

在由多进程组成的分布式系统中，为了保证系统在失效之后进程状态恢复的一致性，某一进程的状态回卷将引起所有与之有依赖关系的进程的后退．已有的依赖关系定义过于严格，该文重新定义了进程状态之间的依赖关系。

In the distributed system, all processes that depend on the process, which must be rolled back, have to be rolled back as well in order to keep the global state consistency. The dependency relation defined in the previous literature is too restrict. A new definition of dependency relation is proposed in this paper, and the influence of a process' rolling back can be reduced.
