Abstract

The error recovery mechanism receives an important position in the system supporting service level agreements (SLAs) for the grid-based workflow. If one sub-job of the workflow is late, a group of directly affected sub-jobs should be re-mapped in a way that does not affect the start time of other sub-jobs in the workflow and is as inexpensive as possible. With the distinguished workload and resource characteristics as well as the goal of the problem, this problem needs new method to be solved. This paper presents a mapping algorithm, which can cope with the problem. Performance measurements deliver good evaluation results on the quality and efficiency of the method.
在SLA上下文中映射基于网格的工作流的错误恢复中的一组作业
错误恢复机制在支持网格工作流服务水平协议(sla)的系统中占有重要地位。如果工作流的一个子作业延迟了,那么一组直接受影响的子作业应该以一种不影响工作流中其他子作业的开始时间并且尽可能便宜的方式重新映射。由于不同的工作量和资源特征以及问题的目标,该问题需要新的解决方法。本文提出了一种映射算法,可以解决这一问题。性能度量提供了对方法的质量和效率的良好评价结果。
