基于指标体系的网格调度算法研究与实现

提出了以代价(Cost)为核心的网格任务调度指标体系,该指标体系在网格用户的QoS需求与网格系统的负载均衡性、系统可靠性与可用性,以及资源拥有者的利益之间建立了一个平衡点。由网格监控统计和计算可获得指标体系的各项指标值,根据基于网格系统与网格用户的需求所制定的指标筛选策略确定网格任务调度原则。以此为基础设计与实现了一套可满足不同网格系统与网格用户需求的算法,通过网格模拟器实验和实际网格应用验证了算法在实际网格环境中的有效性和易用性。

Study on the coordinated development of the rural infrastructure and the rural economy

Through the construction of the comprehensive evaluation index system and the coordination degree model of the rural in- frastructure and the rural economic development level, the author carries out an empirical analysis on the rural infrastructure and economic coordinated development in the country＇s 31 regions. Research shows that the gap between the levels of the development of the rural in-frastructure in China is large, presenting the gradually reducing gradient distribution from the east to the west. The rural infrastructure de- velopment level has significant positive correlation with the level of economic development. For those provinces of the high development level of the rural economy, the infrastructure construction level is also relatively high. From the view of the coordination degree, it presents the obvious ＂dumbbell＂ shape, and there are more provinces which belong to the high quality coordination and the serious imbalance, with the coordinated degree in the eastern regions obviously higher than that in the central and western regions.
