Abstract: This paper analyzes the particularity of job checkpointing in computational grid, and proposes a novel application-level checkpoint mechanism based on job progress description (JPD).It explains the basic idea of such a checkpoint methods, gives the definition of job progress state (JPS) objects and job progress description object, these objects compose the JPD of a job, and the methods of these objects can be used as checkpoint API, It discusses the composition of checkpoint jobs under this checkpoint mechanism.

摘要: 分析了计算网格环境中实现检查点机制的特殊性,提出了一种新的应用级检查点方法:基于作业进展描述的检查点方法。介绍了这种检查点方法的基本思想,定义了构成作业进展描述的作业进展状态对象和作业进展描述对象,这些对象的方法构成了检查点API;讨论了检查点作业的构建。
