Design of data grid scheduling simulator
数据网格任务调度模拟器的设计*

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.
