A study on improving Condor checkpoint mechanism using incremental checkpoint technique
Author(s): 
Pages: 718-721
Year: Issue:  6
Journal: Journal of Henan Agricultural University

Keyword:  机群Condor高吞吐量计算增量检查点技术;
Abstract: 分析了集群作业系统Condor中的检查点机制的实现原理,针对其在执行检查点操作时存在的对计算资源和存储资源的利用的不足,提出了使用增量检查点技术对其进行优化的方案,使得每次进行检查点操作时,只需要保存同上次检查点操作相比改变了的数据,这样可以大大降低检查点操作的空间开销和时间开销,最后通过1个矩阵运算的实例验证了改进方案的可行性.
