| 摘 要： | 容错技术已经成为工作流的研究热点,设置检查点是一种常用的容错方法。针对工作流系统提出一种适应性检查点机制,该机制通过最优化检查点数量和动态设置检查点间隔,大大提高了错误发生情况下任务按时完成的比率,并通过实验验证了该机制优于传统的检查点机制。

| Abstract: | Fault tolerance technology has been a research focus in workflow system.Checkpoints setting is a frequently used method in faults tolerance.In this paper,we propose an adaptive checkpoint scheme for workflow system which optimises the number of the checkpoints and dynamically adjusts the checkpoint intervals,thus remarkably increases the timely task completion ratio in faults presence condition.Experiment results have proved its superior over traditional checkpoint schemes. |
