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.

可扩展的Terascale设施（ETF）是NSF大规模网络基础设施进化的下一个阶段，用于实现科学和工程研究。 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，工具和可视化功能来解决挑战性的科学和工程问题。 2004年10月1日，ETF结束了为期三年的建设量来构建Teragrid，现在正在进入运营阶段。 Teragrid资源合作伙伴包括： 芝加哥大学/阿尔贡国家实验室（UC/ANL），加利福尼亚大学圣地亚哥分校的圣地亚哥超级计算机中心（UCSD），UT-AUSTIN的德克萨斯州高级计算中心，UIUC的国家超级计算应用中心，UIUC，UIUC，印第安纳大学，印第安纳大学，印第安纳大学，普渡大学，Oak Ridge National Laboratory（Oak Ridge National Laboratory（Ornlllllllllllllllllllllllllllllllllllllllllllllll）和Pidcut Gustn， 2004年10月19日，针对Teragrid网格基础设施集团（GIG）提交了另一项提案。在UC/ANL的Charlie Catlett的指导下，演出将负责与合作伙伴网站分包合同的Teragrid开发活动的协调。资源合作伙伴将与NSF达成独立的协议，但将与演出紧密合作以实施Teragrid愿景。 ETF中的ORNL RP项目愿景和目标Othor RP合作伙伴提供高端计算和数据存储资源。 ORNL的独特贡献是仪器数据源与ETF的联系以及中子科学网关的发展，这将使中子科学家可以使用Teragrid资源来分析其数据，包括将实验与模拟的比较。 ORNL将与演出和其他RP的努力紧密合作，以实施ETF范围范围功能的本地实例或利用其他合作伙伴提供的ETF范围的服务，例如Teragrid Operations Center。中子科学应用程序将通过科学网关部署，并使用ETF广泛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，以创建一个独特的大规模研究机构，以供国家利益。该提案概述了ORNL通过为中子科学界提供这种独特的计算科学设施的计划，概述了ORNL作为RP参加Teragrid团队的计划。美国能源部（DOE）在ORNL建造了下一代中子来源，即14亿美元的SNS。 SNS将比世界上任何其他设施提供的通量大数量级，并将在审查的基础上向全国所有科学家（独立于资金来源）提供。有了这一新功能，中子科学界正面临更大的数据集，并且是数据分析和仿真的关键点。他们认识到需要新方法来管理和分析数据以优化光束时间和科学输出。 Teragrid将提供他们需要的新功能。主要目标社区是所有中子散射设施的用户。这是按照每个设施数千用户的顺序（许多科学家使用了多个设施）。美国有五（5）个设施，全球几十个设施。 ORNL RP不能也不认为这些用户将仅依靠NSTG和TeraGRID来解决新兴问题的解决方案。必须赢得他们的忠诚。该RP成功的关键指标之一是它可以说服这个社区使用这些资源的程度。关键是提供一个基础设施，该基础设施有助于社区超越原本可以完成的工作。其次，在其他大型用户设施（如光源和显微镜中心）将对科学的行为产生影响。
