Extensible Terascale Facility (ETF): Bringing Neutron Science to the TeraGrid

橡树岭国家实验室由高级计算基础设施部提供的一项为期三年的合作协议资助，金额为3,898,743美元，用于整合橡树岭国家实验室可用的中子散射资源和可扩展太万兆级设施（ETF）。提供资金，通过位于亚特兰大的新创建的ETF中心，从ORNL建立10gb /秒的连接。中子散射为材料的结构和动力学提供了一种独特的探测方法。它被广泛应用于许多科学领域，包括：纳米科学、基因组学和蛋白质组学、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、固态物理、半导体制造、工程和地球科学。由于该Terascale扩展奖提供的资金，ORNL及其大学合作伙伴（杜克大学、佛罗里达州立大学、佐治亚理工学院、北卡罗莱纳州立大学、田纳西大学、弗吉尼亚大学、弗吉尼亚理工学院和州立大学）将通过东南TeraGrid中子科学扩展项目（SETENS）将中子科学带入TeraGrid。SETENS将通过以下方式实施：1)建立从ORNL到芝加哥ETF中心的高带宽通信链路；2)在ORNL计算科学中心的IBM Power-4和高性能存储系统上部署TeraGrid通用软件堆栈；3)开发和部署支持将高通量同位素反应堆（HFIR）和散裂中子源（SNS）集成到TeraGrid所需的新网格中间件；4)开发和部署分布式中子散射实验数据分析（DANSE）软件系统的网格化版本。SETENS将产生更广泛的影响，而不仅仅是为ETF的科学用户提供访问ORNL中子资源的机会。通过亚特兰大的TeraGrid扩展提议将促进未来的区域和国家网络工作，包括南部十字路口，国家Lambda铁路，以及其他高性能研究和一般用户网络。SETENS将为网格技术的成功应用提供清晰的早期前景，从而加速网格技术的知识、教学、学习和成功。通过大学合作伙伴的参与，SETENS将促进计算机、计算和中子科学与工程研究领域的教育，作为完成科学中子散射研究的一部分。

Oak Ridge National Laboratory is funded by a three-year Cooperative Agreement from the Division of Advanced Computational Infrastructure in the amount of $3,898,743 to integrate the neutron scattering resources available at Oak Ridge National Laboratory with the Extensible Terascale Facility (ETF). Funding is provided to establish a 10-gigabit/second connection from ORNL through a newly created ETF hub to be located in Atlanta. Neutron scattering provides a unique probe of the structure and dynamics of materials. It is widely used in numerous scientific fields including: nanoscience, genomics and proteomics, polymer science, chemistry, soft condensed matter, biotechnology, biology, materials science, metallurgy, solid-state physics, semiconductor manufacturing, engineering and earth sciences. As a result of the funding provided through this Terascale Extension Award, ORNL and its university partners (Duke University, Florida State University, Georgia Institute of technology, North Carolina State University, University of Tennessee, University of Virginia, and Virginia Polytechnic Institute and State University) will bring neutron science to the TeraGrid through a Southeastern TeraGrid Extensions for Neutron Science, or SETENS. SETENS will be put into place by: 1) establishing a high-bandwidth communication link from ORNL to the Chicago ETF hub, 2) deploying the TeraGrid Common Software Stack on the IBM Power-4 and High Performance Storage System in ORNL'S Center for Computational Sciences, 3) developing and deploying the new grid middleware needed to support integration of the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS) into the TeraGrid, and 4) developing and deploying grid-enabled versions of the distributed Data Analysis for Neutron Scattering Experiments (DANSE) software system.SETENS will have a broader impact than simply providing ETF scientific users with access to ORNL's neutron resources. The proposed extension of the TeraGrid through Atlanta will facilitate future regional and national networking efforts, including the Southern Crossroads, National Lambda Rail, and other high-performance research and general user networks. SETENS will accelerate the knowledge, teaching, learning, and success of grid technologies by providing clear early prospects for successful applications. Through the involvement of the university partners, SETENS will spur education in computer, computational and neutron science and engineering research areas as part of the accomplishment of the scientific neutron scattering research.
