项目摘要

'The Grid' is the next leap in computer interconnectivity. The Internet and the World Wide Web are increasingly an integral part of people's lives, helping the world share information and transfer data quickly and easily. In the same way as we now share files and facts over the global network of computers, in the future the Grid will let us share other things, such as processing power and storage space. The Grid is a practical solution to the problems of storing and processing the large quantities of data that will be produced by industry and the scientific communities over the next decade. Particle physicists are waiting for 2007 when a new particle accelerator opens in the world's largest particle physics laboratory, CERN. The Large Hadron Collider (LHC) will be the most powerful instrument ever built to investigate fundamental physics. Once this is fully functional the amount of data being produced will be massive. All this will be too much for one institution to handle so they need to share resources i.e. to use distributed computing. The Grid is built on the same Internet infrastructure as the web, but uses different tools. Middleware is one of these tools. In a stand alone computer the resources allocated to each job are managed by the operating system e.g. Windows, Linux, Unix, Mac OS X. Middleware is like the operating system of a Grid, allowing users to access resources without searching for them manually. GridPP has developed middleware for the Grid, in collaboration with other international projects. Due to GridPP's open source policy, the middleware can evolve and be improved by the people who use it. Distributed computing has been available to scientists for some time but, in general, the use of different sites has to be negotiated by each scientist individually. They need a separate account on each system and jobs have to be submitted and results collected back by hand. Current distributed computing means the user has a lot of work to do to get their results. This is where the idea of Grid computing comes in. Middleware lets users simply submit jobs to the Grid without having to know where the data is or where the jobs will run. The software can run the job where the data is, or move the data to where there is CPU power available. Using the Grid and middleware, all the user has to do is submit a job and pick up the results. Acting as the gatekeeper and matchmaker for the Grid, middleware monitors the Grid, decides where to send computing jobs, manages users, data and storage. It will check the identity of the user through the use of digital certificates. A digital certificate is a file stored securely on a user's computer which allows the Grid to correctly identify a user. The certificates are given to a user by the Certification Authority, with numerous steps to ensure the person applying is who they say they are. The middleware automatically extracts the users' identity from their digital certificate and uses this to log them in. This means users don't have to remember user names and passwords to log onto the Grid, they're automatically logged on using their Grid certificate. After this seamless identification process the middleware will find the most convenient and efficient places for the job to be run and organise efficient access to the relevant scientific data. It deals with authentication to the different sites being used, runs the jobs, keeps track of progress, lets the user know when the work is complete and transfers the result back.
“网格”是计算机互连的下一个飞跃。互联网和万维网越来越成为人们生活中不可或缺的一部分,帮助世界快速,轻松地传输数据。就像我们现在在全球计算机网络上共享文件和事实的方式一样,将来网格将使我们分享其他内容,例如处理能力和存储空间。网格是解决和处理未来十年将由行业和科学社区生成的大量数据的问题的实用解决方案。粒子物理学家正在等待2007年,当时新的粒子加速器在世界上最大的粒子物理实验室CERN中打开。大型强子对撞机(LHC)将是有史以来最强大的工具,用于研究基本物理学。一旦这完全实用,生成的数据量将是巨大的。对于一个机构来说,所有这些都将是太多的处理,因此他们需要共享资源,即使用分布式计算。网格建立在与网络相同的互联网基础架构上,但使用不同的工具。中间件是这些工具之一。在独立的计算机中,分配给每个作业的资源由操作系统管理,例如Windows,Linux,Unix,Mac OSX。中间件就像网格的操作系统,允许用户无需手动搜索资源即可访问资源。 Gridpp与其他国际项目合作开发了网格中的中间件。由于Gridpp的开源策略,中间件可以由使用它的人来发展并改善。分布式计算已经向科学家使用了一段时间,但是通常,每个科学家必须单独协商不同站点的使用。他们需要在每个系统上单独的帐户,必须提交工作,并手工收集结果。当前的分布式计算意味着用户需要做很多工作来获得其结果。这就是电网计算的想法。中间件使用户只需将作业提交到网格,而不必知道数据在哪里或作业将运行的位置。该软件可以运行数据所在的作业,或将数据移至可用CPU功率的位置。使用网格和中间件,用户要做的就是提交工作并取得结果。中间件充当网格的守门人和媒人,监视网格,决定发送计算作业,管理用户,数据和存储。它将通过使用数字证书来检查用户的身份。数字证书是牢固地存储在用户计算机上的文件,该文件允许电网正确识别用户。证书由认证机构授予用户,并采取了许多步骤来确保申请的人是他们说的。中间件自动从其数字证书中提取用户的身份并使用它来登录它们。这意味着用户不必记住用户名和密码即可登录网格,因此它们会自动使用其网格证书记录。在此无缝识别过程之后,中间件将找到运行该工作的最方便,最有效的地方,并组织有效地访问相关的科学数据。它涉及对所使用的不同站点,运行作业,跟踪进度的身份验证,让用户知道工作何时完成,然后转移结果。
