SCI: TeraGrid Resource Partner

可扩展Terascale设备(ETF)是NSF大规模网络基础设施发展的下一个阶段，用于支持高端计算研究。ETF使研究人员能够通过利用九个资源合作伙伴的集成资源、数据收集、仪器和可视化能力来解决最具挑战性的计算问题。2004年10月1日，ETF完成了一项为期三年的建设工作，以创建这种名为TeraGrid(TG)的分布式环境，我们现在正在进入生产运营阶段。TeraGrid的资源合作伙伴包括：芝加哥大学/阿贡国家实验室、加州大学圣地亚哥分校的圣地亚哥超级计算机中心、德克萨斯大学奥斯汀分校的德克萨斯高级计算中心、加州大学洛杉矶分校的国家超级计算应用中心、印第安纳大学、普渡大学、橡树岭国家实验室和匹兹堡超级计算中心。TeraGrid基础设施组(GIG)的单独提案已于2004年10月19日提交给NSF。在UC/ANL的Charlie Catlett的指导下，一般而言，GIG将负责协调TeraGrid的开发活动，并将分包合同转给合作伙伴网站。资源合作伙伴(RP)将各自与NSF签订独立的合作协议，但将与GIG密切合作，以实现TeraGide的愿景。该提案概述了NCSA作为TeraGrid团队的资源合作伙伴参与的计划，以向不断扩大的用户社区提供对这一计算科学设施的持续访问。这项建议涵盖2004年11月1日至2009年10月31日。为了履行NCSA促进新科学发现的使命，NCSA将其在全天候生产环境中支持工程和科学研究与教育方面的丰富经验和世界级领导地位带到TeraGrid(TG)。作为TG资源提供商(RP)，我们的目标是a)支持应用程序开发和调整，以使用户能够开发高效的网格应用程序；b)提供高质量的计算、数据和可视化服务，以支持先进的科学需求；c)快速响应用户、管理员或其他TeraGrid站点提出的问题；以及d)支持TG网格集成组(GIG)的服务、软件、政策和里程碑。这些努力的结果将是一个稳定、健壮、安全、支持网格的高性能计算和存储环境，支持网格应用程序、科学网关和能力应用程序的开发和执行。为了实现这些目标，NCSA将利用其他活动的专业知识和努力，包括NCSA/SDSC网络基础设施伙伴关系，以最大限度地满足TG用户群体的需求。TG的成功取决于单个网站和GIG独特和集体的优势和能力的整合。NCSA的优势在于应用程序性能工程、高级网格应用程序支持、软件集成、打包和支持、分布式操作和过程、大规模并行文件系统以及数据交换和分析工具、I/O和网络性能分析、安全性以及与存储和可视化集成的大规模计算资源。我们的硬件和软件资源由一支知识渊博、经验丰富、精通高端用户工作的员工作为后盾。将特定地点的生产服务整合到共同的TG用户环境中，将使应用程序团队和用户社区有可能通过最大限度地减少访问多个或不同资源所需的工作量，同时最大限度地提高这些资源的质量和可用性，从而提高其生产率。这将使现有用户能够扩大其科学研究的范围和范围，为新用户和社区提供一个易于使用、高效的环境，并创建一个将成为新科学计划基础的网络基础设施。NCSA在TG中的成功将通过其TG资源在多大程度上被有效利用来解决重要的科学问题来衡量，如尖端研究人员正在研究的那些问题。这份提案概述了NCSA作为TG团队的资源提供者参与的计划。我们将为不断扩大的TG用户社区提供对NCSA管理的不断增长的TG计算科学设施的持续访问。TG RP赠款将几乎全部用于资助经验丰富的NCSA人员，以支持这一设施，并与NCSA的核心NSF支持协调，满足TG用户的需求。附录A包含将九个TG RP提案和TG gig提案联系在一起的共同案文。通过这一RP，我们将在更大的TG努力的背景下，通过无缝使用NCSA的TG和核心资源，使研究社区能够进行他们的科学和工程研究。这包括对分布式计算、以数据为中心的科学、按需计算的支持，以及与各种来源资助的基于网络基础设施的新兴能力的连接。NCSA将与科学家、工程师和其他RP站点合作，帮助实现原本更加困难或根本不可能进行的新研究。NCSA将建立、完善并提供一套高端资源，以支持国家研究社区。这一努力的结果将导致一个可以扩展到其他设施的硬件、软件和网络环境。它还将为其他建设可能包括高端设施的电网提供有价值的信息。最后，NCSA的经验丰富的工作人员将对TG环境的质量和用户在该环境中有效工作的能力产生重大的积极影响。

The Extensible Terascale Facility (ETF) is the next stage in the evolution of NSF large-scale cyberinfrastructure for enabling high-end computational research. The ETF enables researchers to address the most challenging computational problems by utilizing the integrated resources, data collections, instruments and visualization capabilities of nine resource partners. On October 1, 2004, the ETF concluded a three-year construction effort to create this distributed environment called the TeraGrid (TG) and we are now entering the production operations phase.The TeraGrid resource partners inclue: the University of Chicago/Argonne National Laboratory, the San Diego Supercomputer Center at UCSD, the Texas Advanced Computing Center at UT-Austin, the National Center for Supercomputing Applications at UIUC, Indiana University, Purdue University, Oak Ridge National Laboratory, and the Pittsburgh Supercomputing Center.A separate proposal was submitted to NSF on October 19, 2004 for the TeraGrid Grid Infrastructure Group (GIG). Under the direction of Charlie Catlett at UC/ANL, in general, the GIG will be responsible for coordination of development activities for the TeraGrid with subcontracts to the partner sites. The resource partners (RP) will each have independent cooperative agreements with NSF, but will work closely with the GIG to implement the vision of the TeraGrid.This proposal outlines the plan at NCSA to participate as a resource partner in the TeraGrid team to provide the expanding user community with ongoing access to this computational science facility. This proposal covers the period November 1, 2004 through October 31, 2009.To fulfill NCSA's mission of enabling new scientific discoveries, NCSA brings its extensive experience and world-class leadership in supporting engineering and science research and education in a 24x7 production environment to the TeraGrid (TG). Our goals as a TG Resource Provider (RP) are to a) support applications development and tuning to enable users to develop highly effective grid applications, b) offer production-quality computational, data, and visualization services to support advanced science needs, c) respond rapidly to issues raised by users, administrators, or other TeraGrid sites, and d) support the services, software, policies, and milestones of the TG Grid Integration Group (GIG). The result of these efforts will be a stable, robust, secure, grid-enabled high-performance computing and storage environment that supports the development and execution of grid applications, science gateways, and capability applications. In fulfilling these goals, NCSA will leverage expertise and effort from other activities, including the NCSA/SDSC CyberInfrastrcture Partnership, to address the needs of the TG user communities to the greatest extent possible. The success of TG depends on the integration of the unique and collective strengths and capabilities of the individual sites and the GIG. NCSA's strengths are in the areas of application performance engineering, advanced grid applications support, software integration, packaging and support, distributed operations and procedures, large-scale parallel file systems and data-exchange and analysis tools, I/O and network performance analysis, security, and large-scale compute resources integrated with storage and visualization. Our hardware and software resources are backed by a knowledgeable and experienced staff well versed in working with high-end users. The integration of site-specific production services into the common TG user environment will make it possible for applications teams and user communities to increase their productivity by minimizing the effort required to access multiple or different resources while maximizing the quality and availability of those resources. This will enable current users to expand the scope and range of their scientific research, provide an easy-to-use, highly productive environment for new users and communities, and create a cyberinfrastructure that will be the basis for new scientific programs. NCSA's success within the TG will be measured by the degree to which its TG resources are effectively used to solve important scientific problems such as those being investigated by leading edge researchers.This proposal outlines NCSA's plan to participate as a resource provider on the TG team. We will provide to the expanding TG user community ongoing access to the growing NCSA-managed TG computational science facility. The TG RP grant will be used almost entirely to fund highly experienced NCSA personnel to support this facility and to serve the needs of TG users in coordination with NCSA's Core NSF support. Appendix A contains common text that links the nine TG RP proposals and the TG GIG proposal. Through this RP, we will empower research communities to do their science and Engineering research by seamless use of NCSA's TG and Core resources in the context of the larger TG effort. This includes support for distributed computation, data-centric science, on-demand computing, and connection to a broad range of emerging cyberinfrastructure-based capabilities funded from a variety of sources. Working together with scientists, engineers, and other RP sites, NCSA will help enable new research that would otherwise be much more difficult, or simply impossible, to carry out. NCSA will build, improve, and make available a set of high-end resources in support of the national research community. The results of this effort will lead to a hardware, software, and networking environment that can be extended to other facilities. It will also provide valuable information to others building grids that may include high-end facilities. Finally, NCSA's experienced staff will have a substantial positive impact on the quality of the TG environment and on the ability of users to work effectively in that environment.
