摘要
针对粗粒度网格中的调度问题,提出了一种分组调度策略,将相似作业进行分组,再将分组提交到合适的运算资源.与细粒度网格相对比,作业以细分的形式执行并最终返还用户.该策略能有效减少开销,提高处理能力.GridSim Toolkit模拟器验证了所提出方法的有效性.
A grouped-scheduling strategy for coarse-grained grid application was designed.The similar jobs were grouped and dispatched to appropriate computing resources.Compared with the fine-grained form in which each job is processed individually and then sent back to the user,this strategy can effectively decrease the overhead time and increase the processing efficiency.GridSim Toolkit was used to testify its advantage with simulation experiments.
