| 摘 要： | 针对网格环境下的作业调度问题,提出了适合异构机群作业调度的三种网格调度系统模型:作业本地调度模型、作业共享调度模型和作业多址调度模型.建立了多址作业在三种网格调度系统模型下的性能模型.理论分析得出如下结论:同构情况下,多址作业调度应遵循先单址后多址、先本地后异地的资源选择策略;异构情况下,该策略失效,需对所有资源组合进行遍历,可设计启发式调度算法获得近优解.

| Abstract: | Cooperation of massive parallel processor systems in different management-domains lies on the design of multi-domain job scheduling models.Three multisite grid job scheduling models,named local,sharing,multisite job scheduling models,are presented to overcome the heterogeneity and low bandwidth in computational grid.The job performance models on different scheduling models are analyzed in theory.The analysis results show that when the sites are homogeneous,multisite job scheduling should prefer the local and single site resources to multisite;when the sites are heterogeneous,these heuristics are invalid so that new heuristics should be designed to achieve the sub-optimum solutions. |
