基于SLA对作业执行进行有效管理的理论,在资源消费者和资源提供者之间加入协调者的SLA合同管理架构,提出了该架构的经济网格执行管理调度策略,并对该策略的性能进行了模拟分析.分析结果表明,该策略对传统经济网格的资源调度算法进行了扩展,使用户能够更加灵活地在执行时间与代价之间进行权衡.
Based on the theory of SLA for effective management of tasks, an SLA contract management framework with a coordinator between the resource provider and resource customer was developed. The management strategy for economic grid operation of the framework was proposed, and the performance of the strategy was also studied by numerical simulation. The analysis shows that the strategy prompts the further development of the resource scheduling algorithm of the conventional economic grid, and it makes the resource customer more flexible to adjust the weights between cost and runtime.
