基于双重服务质量约束的网格资源调度策略

Grid resource scheduling strategy based on double QOS constraints

为提高网格资源利用率,以及用户对网格服务的满意程度,提出了基于双重服务质量约束的网格资源调度算法Senior。该算法在实现过程中,针对网格作业和资源的属性,通过具体化参数信息,推导出调度策略的模式;依据经典调度算法的相关思想,将任务完成期限和网络带宽确定为双重属性约束,并应用GridSim工具包对相关调度算法进行了测试。通过对仿真结果中的数据进行分析和比较,验证了新的调度算法Senior在解决类似问题时的优势。

To improve the utilization ratio of resources and users＇ satisfaction degree of grid services, grid resource scheduling algorithm based on double Quality of Service （QoS） named Senior was proposed. In the implementation process of scheduling algorithm, the mode of scheduling strategy was derived, according to the attributes of job and resource, and the specified parameter information. Double constraints of gridlets deadline and network bandwidth were defined as double attribute constraints based on the thought of classic scheduling theory, and the related algo- rithms were sirn, ulated by the GridSim toolkits. Simulation results showed that new double QoS constraint algorithm Senior was superior in solving such kind of issues by comparing and analyzing the result data.
