摘要
设置检查点是容错计算机系统进行故障恢复的重要手段。检查点的开销则是影响其性能的一个主要因素。许多文献已指出检查点开销主要是来自于对进程状态的保存。文章采用时间序列分析的方法对进程状态大小变化情况进行分析和预测,动态选择恰当的检查点时间间隔,减少检查点时需保存的进程状态量,从而减小了检查点的开销。
Checkpoint is an important technology to save and rollback the state of the Process. The overhead of checkpoint is a major factor that has effect on the performance. Some papers had mentioned that the overhead of checkpoint mainly dues to save the process’s state into stable storage. In this paper, using Time Series Analysis method to modeling and forecast the state size of process, we can select the appropriate interval of checkpoint, which can reduce the overhead.
