关于异构环境下网格计算模式及体系结构的设计研究

A research on the grid computing mode and architecture design under the condition of heterogeneity

与机群系统相比,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。网格计算模式的体系结构是具有一定智能的分层结构。参考5层沙漏结构思想和前人的研究成果,研究设计具有资源底层、安全调度层、抽象接口层、中间件层、应用接口层和应用层等6个层面的网格计算系统多层体系结构。

Compared with cluster system, 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, tool-softwares, video dynamic alternation between man and computer. The architecture of grid computing mode is a kind of hierarchical architecture with some intellectual capacity. Referring to the idea of Five-Level Sandglass Architecture and predecessor＇s productions, the author has discussed and designed Multi-level Architecture of grid computing system with six levels of resource base, security dispatch, abstract interface, middleware, applied interface and application.
