【摘要】 随着第三次互联网浪潮的到来，“即取即用”的网络应用模式成为资源共享的发展趋势。网格不是因特网的一种新名词，它并不是要抛弃和完全取代因特网。它将建筑在因特网的基础之上，不过比当前的因特网性能更高、功能更强、应用更广。 网格在产生的初期主要集中在高性能科学和工程计算领域中，但随着网格研究的不断发展，网格的应用领域不断地扩大，出现了适用于不同应用领域的网格技术，直接服务于生产和各种商业活动。此时，如何恰当地利用现有工具和技术，更好地实现网格应用变得越来越重要了，这也是本课题希望达到的目的。 论文通过对网格体系结构OGSA以及网格支撑平台Globus的分析和研究，探讨了实现网格应用的一些关键性技术。具体在以下几个方面做了一些工作： (1) 揭示网格及网格计算深层涵义，介绍网格的国内外研究和发展现状； (2) 研究和分析通用的网格体系结构(五层沙漏结构和开放网格服务体系结构OGSA)； (3) 研究和分析Globus项目及其Globus支撑平台(也称Gloubs工具包)，并就Globus平台上一些应用开发工具进行了简单介绍； (4) 研究和分析在OGSA体系结构和Globus平台基础上，实现网格应用的关键性技术；并以XPort为例，对网格在分布式仪器系统中的应用开发做了实例的探讨和分析。 最后，希望该论文能起到“抛砖引玉”作用，促进我国网格计算的发展。更多还原

【Abstract】 With the third tide of the Internet, application based on GRID technology has become a tendency of resource share domain. GRID is not a new word for Internet, neither is it mean to abandon or replace Internet. It is based on the Internet with higher quality and stronger function and wider user.GRID mainly concentrates on high-performance science and engineering calculation field when it initially produces. But with the rapid development of studying GRID, the application of GRID is expanding constantly. GRID technology which is suitable for different applications has appeared, and it has already served production and various kinds of business activities directly. Now, how to utilize existing tools and technology appropriately, and make the best of realizing GRID application becomes more and more important, and this is the purpose that this subject hopes to achieve too.Through studying and analyzing the GRID architecture -OGSA and the supporting platform - Globus, the paper have probed into some key technology of realizing GRID application. I have done some concrete jobs in the following respects :(1) Explain and define the deep meaning of GRID and GRID Computing, and introduce the domestic and international current research and development situation of GRID;(2) Study and analyse the universal GRID architecture (the Five Sand Filter Structure and the Open GRID Service Architecture OGSA);(3) Study and analyse the Globus project and the Globus platform (or called Globus toolkits ), and carry on a simple introduction on some applied development tools that base on the Globus platform;(4) Study and analyse the key technology of GRID application on the basis of the OGSA structure and the Globus platform; And take XPort as an example , make the discussion and analysis of the instance to the GRID application in the distributed instrument system.Finally, I hope this paper can play a "casting a brick to attract jade" role , and promotes the development of GRID application in our country.更多还原
