基于optorsim的网格作业调度和数据复制策略仿真
Grid Job Scheduling and Data Replication Algorithms Simulations Based on Optorsim
【摘要】 利用网格仿真软件optorsim,在不同的数据网格场景中测试研究了几种作业调度和数据复制策略对网格的影响。结果表明作业调度和数据复制策略的选择对网格资源利用率和平均作业执行时间的影响很大。
【Abstract】 In a variety of data Grids scenarios, the effects of various job scheduling and data replication strategies are simulated and researched in optorsim. Results show that the choice of scheduling and data replication strategies can have a large effect on both job throughput and the usage factor of the consumption of Grid resources..
