摘要
地质调查工作中数据密集、计算密集、资源分布、异构等问题制约了行业应用和信息化发展 网格 (grid)是新一代高性能计算环境和信息服务基础设施 ,能够实现动态跨地域的资源共享和协同工作 国家地质调查应用网格 (NGG)基于网格技术 ,以“服务”为中心 ,提出并构建了从信息获取、处理到应用的完整的 7层体系结构 同时结合行业应用需求 ,着重研究资源管理、资源交易、服务等关键技术 ,在Petri网和图论的基础上提出了一种新的服务链模型 (服务 /资源网 ) 。
National geological survey is characterized by data-intensiveness, computing-intensiveness, distribution of resources, and heterogeneous information systems. As an innovative high performance computing environment and information services infrastructure, a grid can meet geological survey application requirements by its dynamic, distributed resources sharing and collaboration. Based on grid computing, national geological application grid(NGG), a novel service-oriented architecture with seven levels from information acquirement, processing to application is proposed. To solve application problems some crucial technologies of NGG are discussed in detail, such as resource management, resource trading, service chain, etc. Moreover a new service chain model (named service/resource net) based on Petri net and graph theory is presented.
