The Extensible Terascale Facility (ETF), or "TeraGrid" involves nine resource providers (RP's) operating high-performance computing, information, and visualization facilities interconnected with a dedicated optical network and integrated with a set of common software that presents the user community with a cohesive set of resources and services. On October 1, 2004, the ETF will conclude a three-year construction effort to create this distributed environment and will transition into an operational state. This proposal outlines a set of services to be provided at Oak Ridge National Laboratory (ORNL) as part of the TeraGrid system.The ORNL RP's goal is to bring a new scientific community to the TeraGrid - Neutron Science, and to provide them with computing and data storage resources needed to make full use of next generation neutron sources. Neutron scattering provides a unique probe of the structure and dynamics of materials. It has found application in many fields, including nanoscience, polymer science, chemistry, soft condensed matter, biotechnology, biology, materials science, metallurgy, solid-state physics, semiconductor manufacturing, engineering, earth sciences, genomics, and proteomics. A next-generation neutron source, the $1.4 billion Spallation Neutron Source (SNS), is being built by the U.S. Department of Energy (DOE) at ORNL. The SNS has an order of magnitude greater flux than any other facility in the world. Neutron scattering centers provide beam time on a peer-reviewed merit basis to researchers in all areas of science.With over a thousand users a year, these facilities are national and international scientific resources. Recent facilities upgrades and the commissioning of SNS will greatly increase beam intensities and available beam time. Foreseeing the massive increase in data, the neutron-science community is discussing how to proceed. They recognize the need for new ways to manage data to optimize both beam time and scientific output. The ORNL RP effort focuses on bridging the Neutron Science (particularly the SNS) and Computational Science communities to provide transparent access to the massive TeraGrid computing and data storage resources. The ORNL RP is creating and will operate an enclave to make Neutron Science data streams and data stores available for reduction and analysis on TeraGrid resources and to facilitate the comparison of experimental data with computational simulation. The ORNL RP construction effort is building the network and computer systems infrastructure needed to access the SNS through the TeraGrid. The early operations effort will bring TeraGrid resources to Neutron Science users by operating the resources built during the ETF construction phase and continuing to develop the infrastructure to enable neutron scientists to use the TeraGrid to leverage their work. The ORNL RP effort is also exploring collaborative opportunities with other Neutron facilities in the US and internationally.

可扩展万亿级设施（ETF）或“TeraGrid”涉及九个资源提供商（RP），这些资源提供商运营高性能计算、信息和可视化设施，这些设施与专用光网络互连，并与一组通用软件集成，为用户社区提供一组有凝聚力的资源和服务。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。该提案概述了橡树岭国家实验室（ORNL）作为TeraGrid系统的一部分提供的一系列服务。ORNL RP的目标是为TeraGrid带来一个新的科学社区-中子科学，并为他们提供充分利用下一代中子源所需的计算和数据存储资源。中子散射提供了一个独特的探测材料的结构和动力学。它已在许多领域中得到应用，包括纳米科学、聚合物科学、化学、软凝聚态物质、生物技术、生物学、材料科学、冶金学、固态物理学、半导体制造、工程学、地球科学、基因组学和蛋白质组学。美国能源部（DOE）正在ORNL建造下一代中子源，即价值14亿美元的Sputterus中子源（SNS）。SNS的通量比世界上任何其他设施都大一个数量级。中子散射中心为所有科学领域的研究人员提供经过同行评议的束流时间。这些设施每年有1000多名用户，是国家和国际科学资源。最近的设施升级和SNS的试运行将大大增加射束强度和可用射束时间。预见到数据的大量增加，中子科学界正在讨论如何继续下去。他们认识到需要新的方法来管理数据，以优化射束时间和科学产出。 ORNL RP的工作重点是连接中子科学（特别是SNS）和计算科学社区，以提供对大规模TeraGrid计算和数据存储资源的透明访问。ORNL RP正在创建并将运行一个飞地，以使中子科学数据流和数据存储可用于TeraGrid资源的减少和分析，并促进实验数据与计算模拟的比较。ORNL RP建设工作正在建设通过TeraGrid访问SNS所需的网络和计算机系统基础设施。早期运营工作将通过运营ETF建设阶段构建的资源，并继续开发基础设施，使中子科学家能够使用TeraGrid来利用他们的工作，从而为中子科学用户带来TeraGrid资源。ORNL RP的努力也在探索与美国和国际上其他中子设施的合作机会。
