| 摘 要： | QoS是网格任务执行的基本保证，针对网格资源选择中复杂的QoS参数处理过程，将QoS参数按照用户的关心程度进行分类，提出了一种简化的参数处理模型，设计了支撑该模型的QoS体系结构，给出了优化资源调度过程的算法。实验表明，该模型提高了系统吞吐量和资源匹配成功率，缩短了任务的平均完成时间，最终实现了整个系统资源利用率的提高。

| Abstract: | QoS is a key requirement for applications to ensure tasks running in grid, but the processing of QoS parameters is too complicated currently. A new grid QoS model that optimized the QoS process was proposed. As to the model requirement, QoS infrastructure was presented, and scheduling optimizing algorithm was described based on the model. The experiments show that the scheduling optimizing algorithm is efficient on task completion time and improves the resource utilization ratio within grid computing economy environments. |
