针对Nimrod-G系统中DBC调度策略只能集中对一个目标(时间或费用)进行优化的问题,提出了基于平均成本的DBC分类调度算法,该算法综合考虑了任务调度的完成时间和费用。通过GridSim仿真实验证明,基于平均成本的DBC分类调度算法在均衡完成时间和费用方面有很大的优势,有效的扩展了原有算法。
To solve the problem that a DBC scheduling strategy can only focus on a target (time or cost) in Nimrod-G system, a DBC classification and scheduling algorithm based on average cost is proposed. The algorithm takes the completion time and cost of task scheduling into consideration. The GridSim simulation results show that the DBC classification scheduling algorithm based on average cost has a great advantage in balancing the completion time and cost, effectively expanding the original algorithm.
