摘要
通过对数据网格模型及任务调度过程进行分析,归纳了数据网格任务调度流程,定义了数据网格的任务执行时间和执行花费。对网格模拟器GridSim进行扩展,增加了数据网格任务调度的模拟功能,介绍了扩展后的模拟器体系结构、工作流程和关键技术。通过实验表明,该任务调度模拟器可以满足数据网格优化理论研究的需要,能够对任务调度策略的性能进行比较。
The scheduling process of data grid was summarized,the time and the cost of job execution was defined by analysis the data grid model and some data grid project.The job scheduling simulator of data grid was designed by extending the GridSim.The architecture,workflow and the key technologies of this simulator was introduced.Finally,it proves that this job scheduling simulator makes it easy to compare various scheduling strategies.
