摘要
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.
