在本文中，我们分析了i)检查点成本和最优检查点间隔之间的关系以及ii)检查点成本和处理器（进程）数量之间的关系，我们还确定了执行容错MPI应用程序所需的最优处理器（进程）数量。我们提出了一项实验研究，其中我们使用了具有威布尔分布和指数分布的最优检查点重启模型(1)来确定最优检查点间隔。我们观察到，使用威布尔分布获得的最优检查点间隔产生最小的平均完成时间；与采用指数分布得到的最优检查点间隔进行了比较。
In this paper, we have analysed i) the relationship between the checkpoint cost and the optimal checkpoint interval and ii) the relationship between the checkpoint cost and the number of processors (processes) and we have also determined the optimal number of processors (processes) required for executing the fault tolerant MPI applications. We have presented an experimental study in which, we have used an optimal checkpoint restart model (1) with Weibull's and Exponential distributions to determine the optimal checkpoint interval. We have observed that, the optimal checkpoint intervals obtained using Weibull's distribution, produce minimal average completion time; as compared with the optimal checkpoint intervals obtained using Exponential distribution.
