摘要
地理空间信息网格调度技术,要比传统的高性能计算中的调度技术复杂,原因是如果将全部网格资源作为一个应用程序的调度和执行目标,必将导致通信延迟、成本昂贵、执行低效等。为此,综合考虑应用程序特性、机器特性等,研究设计了地理空间信息网格高性能调度技术中的应用程序调度模型,包括地理空间信息网格应用程序分析;资源特性分析;应用程序分解;性能预测;资源调度;机器选择;任务映射;任务调度;任务调度器和调度器管理模块。以实现为不同的应用程序匹配不同的计算资源,提高计算资源的利用率和应用程序的执行效率。
The geospatial information grid dispatch technology performance computation dispatch technology, the reason is that is more complex than in the traditional high if the complete grid resources takes one application procedure the dispatch and carries out the goal, it will certainly to cause the correspondence delay, cost expensively, carries out the low effect and so on. Therefore, to consider the characteristic of the application procedure synthetical and the machine, research designed in the geospatial information grid high performance dispatch technology application procedure dispatch model, included the geospatial information grid application procedure analysis; resources characteristic analysis; application procedure decomposition; application forecast; resources dispatch; machine choice; duty mapping; duty dispatch; duty dispatcher and dispatcher management module. Take realizes as the different application procedure match different computation resources, enhances the computation resources the use factor and the application procedure carries out the efficiency.
