SCI: TeraGrid Early Operations

可扩展万亿级设施（ETF），或TeraGrid，涉及九个资源提供商，运营高性能计算，信息和可视化设施，与专用光纤网络互连，并与一套通用软件集成，为用户社区提供一套连贯的资源和服务。 2004年10月1日，ETF将结束为期三年的构建工作，以创建这种分布式环境，并将过渡到运行状态。本提案概述了芝加哥大学资源在2005财年前六个月的运作情况。 该提案的重点是最小的资源，将允许生产使用和开发最小的服务需要产生一个系统，是有用的社区。UC资源的重点是什么是典型的TeraGrid资源提供商是在两个不同的领域。第一个领域是提供生产可视化服务，为可视化和图形开发人员提供用户、工具和库。第二个领域是为TeraGrid IA-64用户运行软件开发和测试平台。这个测试平台服务将对整个TeraGrid社区有用，提供当前系统中缺少的基础设施，并使抢先体验能够访问新的软件栈和未来版本的操作系统。用户将能够以一种方式访问TeraGrid感知的可视化应用程序，对用户来说，这似乎是一个桌面可视化解决方案，但实际上利用了丰富的TeraGrid可视化资源。将为特定可视化工具或并行图形的开发人员提供所需的基础设施。随着时间的推移，这种基础设施将包括对低级服务的访问，这些服务可以组合在一起形成定制应用程序。该测试平台服务将支持IA-64架构上的当前和原型TeraGrid软件栈进行生产分析，将能够对新软件组件进行主动测试，并将在大规模部署之前促进TeraGrid用户项目的长期开发。

The Extensible Terascale Facility (ETF), or TeraGrid, involves nine resource providers operating high-performance computing, information, and visualization facilities, interconnected with a dedicated opticalnetwork and integrated with a set of common software that presents the user community with a cohesiveset of resources and services. On October 1, 2004, the ETF will conclude a three-year constructioneffort to create this distributed environment and will transition into an operational state. This proposaloutlines operation for the University of Chicago resource during the first six months of FY 05. The proposalfocuses on the minimal resources that will allow for production use and a development of minimal servicesneeded to produce a system that is useful to the community.The focus of the UC resource beyond what is typical of TeraGrid resource providers is in two distinct areas. The first area is in providing production visualization services that enable users and tools and librariesfor visualization and graphics developers. The second area is in operating a software development and testing platform for the TeraGrid IA-64 users. This testbed service will be of use to the entire TeraGrid community, providing infrastructure missing in the current system and enabling early access to new software stacks and to future versions of operating systems. Users will be able to access TeraGrid-aware visualization applications in a way that, to the user, appears to be a desktop visualization solution but in reality makes use of the rich TeraGrid visualization resources. Needed infrastructure will be provided for developers of specific visualization tools or parallel graphics. Over time this infrastructure will include access to low-level services that can be put together to form custom applications. The testbed service will support current and prototype TeraGrid software stacks on the IA-64 architecture for production analysis, will enable active testing of new software components, and will foster long-term development for TeraGrid user projects before wide-scale deployment.
