网格经济环境中提高资源效益的作业控制策略

Job admission control strategy for increasing profit in grid economy

在网格经济环境基础上,重点分析了商业计算服务的三个重要因素:满足服务等级协议(SLA);保证资源稳定性;盈利.将其量化作为重要参数应用于对资源管理策略性能的单独分析和综合分析中,并从资源提供商的利益考虑,提出了一种作业准入控制策略,让资源选择性地接收运行用户作业,充分利用自身资源,最大化自身利益,并用GridSim Toolkit模拟器验证了其有效性.从实验结果可以看出,该策略能有效增加资源商的收益.

Three essential objectives were analyzed for a commercial computing service based on the grid economy environment: meet SLA,maintain reliability and earn profit.Two evaluation methods were developed which are separate and integrated risk analysis to analyze the effectiveness of resource management policies in achieving the required objectives.An admission control strategy was designed to maximize the providers′ benefit and used the GridSim Toolkit to testify its availability with simulation experiments.From the results,we can see that this strategy increase the resource providers′ benefit effectively.
