异构环境下地理空间信息网格计算模式及体系结构研究

与机群系统相比,地理空间信息网格计算模式的优势在于可以更好地解决资源的异构性问题,支持资源的柔性伸缩及多种并行编程环境,支持科学计算库与工具软件,支持可视化动态人机交互。地理空间信息网格计算模式的体系结构是具有一定智能的分层结构。本文参考五层沙漏结构思想和前人的研究成果,研究设计了具有资源底层、安全调度层、抽象接口层、中间件层、应用接口层和应用层等六个层面的地理空间信息网格计算系统多层体系结构。

Research on the geospatial information grid computing mode and architecture design under the condition of heterogeneity

Compared with cluster system,geospatial information grid computing mode takes on unparalleled advantages,because it can solve the problem of resource heterogeneity,supporting resource flexible retractility,many kinds of parallel programme environments,scientific computing database and tool-softwares,and video dynamic interaction between man and computer.The architecture of geospatial information grid computing mode is a kind of hierarchical structure with some intellectual capacity.Referring to the idea of Five-Level Sandglass Architecture and predecessor's productions,the author discussed and designed Multi-level Architecture of Geospatial Information Grid Computing System with six levels including resource base,security dispatch,abstract interface,middleware,applied interface and application.
