The Extensible Terascale Facility (ETF) is the next stage in the evolution of NSF large-scale cyberinfrastructure for enabling scientific and engineering research. The ETF enables researchers to address challenging scientific and engineering problems by utilizing the integrated computing resources, data collections, instruments and visualization capabilities of nine resource partners (RP). On October 1, 2004, the ETF concluded a three-year construction effort to construct the TeraGrid and is now entering the operations phase. The TeraGrid resource partners include; the University of Chicago/Argonne National Laboratory (UC/ANL), the San Diego Supercomputer Center at University of California, San Diego (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 (ORNL), 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, the GIG will be responsible for coordination of development activities for the TeraGrid with subcontracts to the partner sites. The resource partners will each have independent agreements with NSF, but will work closely with the GIG to implement the TeraGrid vision. ORNL RP Project Vision and GoalsOther RP partners in the ETF provide high-end computing and data storage resources. The unique contribution of ORNL is the connection of instrument data sources to the ETF and the development of a neutron science gateway that will allow neutron scientists to use TeraGrid resources to analyze their data, including comparison of experiment with simulation. ORNL will work closely with the GIG and other RP efforts to implement local instances of ETF-wide functionality or utilize ETF-wide services provided by the other partners, for example the TeraGrid Operations Center. Neutron science applications will be deployed through a science gateway and use ETF wide computing and data storage resources. ORNL RP sees the ETF partnership not as a collaboration between competing institutions but as a collaboration of complementary services and functionality to create a unique, large scale research facility for the national interest. This proposal outlines the plan for ORNL to participate as a RP in the TeraGrid team by providing the neutron science community with access to this unique computational science facility. A next-generation neutron source, the$1.4 billion SNS, is being built by the U.S. Department of Energy (DOE) at ORNL. The SNS will provide an order of magnitude greater flux than any other facility in the world and will be available to all of the nation's scientists, independent of funding source, on a reviewed basis. With this new capability, the neutron science community is facing order of magnitude larger data sets and is at a critical point for data analysis and simulation. They recognize the need for new ways to manage and analyze data to optimize both beam time and scientific output. The TeraGrid will provide the new capabilities that they need.The primary target community is all users of neutron scattering facilities. This is on the order of a few thousand users per facility (many scientists use more than one facility). There are five (5) facilities in the U.S. and a few dozen world-wide. The ORNL RP cannot and does not assume that these users will rely exclusively on the NSTG and the TeraGrid as a solution to their emerging problems. Their allegiance must be earned. One of the key metrics of this RP's success is the extent to which it can persuade this community to use these resources. The key will be to provide an infrastructure that helps the community reach beyond what would otherwise have been accomplished. Secondarily, there will be impacts on the conduct of science at other large user facilities such as light sources and microscopy centers.

可扩展万亿级设施（ETF）是 NSF 大规模网络基础设施发展的下一阶段，以支持科学和工程研究。 ETF 使研究人员能够利用九个资源合作伙伴 (RP) 的集成计算资源、数据收集、仪器和可视化功能来解决具有挑战性的科学和工程问题。 2004年10月1日，ETF完成了为期三年的TeraGrid建设工作，现已进入运营阶段。 TeraGrid 资源合作伙伴包括： 芝加哥大学/阿贡国家实验室 (UC/ANL)、加州大学圣地亚哥分校 (UCSD) 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、UIUC 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 (ORNL) 和匹兹堡超级计算中心。 2004 年 10 月 19 日，向 NSF 提交了一份关于 TeraGrid 网格基础设施小组 (GIG) 的单独提案。在 UC/ANL 的 Charlie Catlett 的指导下，GIG 将负责协调 TeraGrid 的开发活动，并向合作伙伴站点分包。资源合作伙伴将分别与 NSF 签订独立协议，但将与 GIG 密切合作以实现 TeraGrid 愿景。 ORNL RP 项目愿景和目标 ETF 中的其他 RP 合作伙伴提供高端计算和数据存储资源。 ORNL 的独特贡献是将仪器数据源与 ETF 连接起来，并开发中子科学网关，使中子科学家能够使用 TeraGrid 资源来分析他们的数据，包括实验与模拟的比较。 ORNL 将与 GIG 和其他 RP 工作密切合作，实施 ETF 范围内的功能的本地实例，或利用其他合作伙伴（例如 TeraGrid 运营中心）提供的 ETF 范围内的服务。中子科学应用程序将通过科学网关进行部署，并使用 ETF 范围内的计算和数据存储资源。 ORNL RP 认为 ETF 合作伙伴关系不是竞争机构之间的合作，而是互补服务和功能的合作，旨在为国家利益创建独特的大型研究设施。该提案概述了 ORNL 作为 TeraGrid 团队的 RP 参与的计划，为中子科学界提供了使用这一独特的计算科学设施的机会。美国能源部 (DOE) 正在橡树岭国家实验室 (ORNL) 建造下一代中子源，即耗资 14 亿美元的 SNS。 SNS 将提供比世界上任何其他设施大一个数量级的通量，并将在经过审查的基础上向全国所有科学家开放，不受资金来源的影响。凭借这一新功能，中子科学界面临着数量级更大的数据集，并且正处于数据分析和模拟的关键点。他们认识到需要新的方法来管理和分析数据，以优化光束时间和科学输出。 TeraGrid 将提供他们所需的新功能。主要目标社区是中子散射设施的所有用户。每个设施大约有几千名用户（许多科学家使用多个设施）。美国有五 (5) 个设施，全球有几十个。 ORNL RP 不能也不假设这些用户将完全依赖 NSTG 和 TeraGrid 作为解决其新出现问题的方法。必须赢得他们的效忠。该 RP 成功的关键指标之一是它能够在多大程度上说服该社区使用这些资源。关键是提供一个基础设施，帮助社区超越原本可以实现的目标。其次，将对光源和显微镜中心等其他大型用户设施的科学研究行为产生影响。
