基于网格的煤矿安全应用网格体系研究

煤矿安全应用工作中数据信息分布、计算资源闲置、异构以及计算功能单一严重制约着行业应用和信息化的发展。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。该文基于新兴的网格技术，参照OGSA体系，提出并构建了从信息获取、处理到应用的完整的煤矿安全应用网格（CMSAG）体系结构。同时结合行业应用需求，着重研究了其资源表示、资源管理、存储访问以及数据缓存等关键技术，最后通过具体应用示例的工作流程论证了该网格体系的应用模式。

Study on Grid-based System Framework of Coal Mine Safety Application Grid

Coal mine application survey is characterized by distribution of data, free computing resource, heterogeneous information systems and the computing functions singleness. As an innovative high performance computing environment and information service infrastructure, a grid can meet geological survey application requirements by its dynamic, distributed resources sharing and collaboration. Based on the grid computing and referred to the OGSA system framework, the system framework of coal mine safety application grid (CMSAG) from information acquirement, processing to application is proposed. To solve the application problems, some crucial technologies of CMSAG are discussed in detail, such as resource expressing, resource management, storage accessing, data storing, etc. At last, it is proved that the system framework is feasible when it comes to a workflow of the material illustration.
