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.

可扩展的Terascale设施（ETF）或“ Teragrid”涉及九个资源提供商（RP）操作高性能计算，信息和可视化设施，与专用的光网络相互联系，并与一组通用软件集成，这些软件与用户社区相结合，以凝聚力集合资源和服务。 2004年10月1日，ETF将结束为期三年的建设工作，以创建这个分布式环境，并将过渡到运营状态。该提案概述了橡树岭国家实验室（ORNL）提供的一系列服务。中子散射提供了材料结构和动力学的独特探针。它在许多领域中发现了应用，包括纳米科学，聚合物科学，化学，软凝结物质，生物技术，生物学，材料科学，冶金，固体物理学，半导体制造，工程，地球科学，基因组学和蛋白质组学。美国能源部（DOE）在ORNL建造了下一代中子来源，即14亿美元的散布中子来源（SNS）。 SNS的通量比世界上任何其他设施都要大。中子散射中心为科学所有领域的研究人员提供了同行评审的优点基础，每年超过一千个用户，这些设施是国家和国际科学资源。最近的设施升级和SNS的调试将大大增加光束强度和可用的光束时间。预见到数据的大量增加，中子科学界正在讨论如何进行。他们认识到需要新的方法来管理数据以优化光束时间和科学输出的需求。 ORNL RP的工作重点是桥接中子科学（尤其是SNS）和计算科学社区，以透明地访问大规模的Teragrid计算和数据存储资源。 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减少和分析Teragrid资源，并促进实验数据与计算模拟的比较。 ORNL RP施工工作正在建立通过TeraGRID访问SNS所需的网络和计算机系统基础架构。早期的运营工作将通过运行在ETF施工阶段建立的资源，并继续开发基础设施以使中子科学家能够利用Teragrid来利用其工作，从而为中子科学用户带来Teragrid Resources。 ORNL RP的努力还在探索与美国和国际其他中子设施的协作机会。
