The TeraGrid Proposal: Cyberinfrastructure for 21st Century Science and Engineering

伊利诺伊大学厄巴纳-香槟分校与加州大学圣地亚哥分校合作，由高级计算基础设施部的一项合作协议资助26,450,500美元，用于建设一个分布式万亿级设施（DTF），该设施将跨越四个机构：1)国家超级计算应用中心，2)圣地亚哥超级计算机中心，3)阿贡国家实验室和4)加州理工学院。他们将与IBM、Intel、Myrinet、Qwest、Oracle和SUN合作，构建一个基于多个万亿级Linux集群的DTF，以及大规模存储档案和数据管理软件。一个40千兆位/秒的光网将连接DTF的组件。DTF硬件将集成，使用Globus中间件和其他由高级计算基础设施合作伙伴（PACI）开发的计算网格技术，创建一个具有11.6 TF计算能力和525 TB磁盘存储的系统，以支持太级计算（NCSA的6.1 TF和153 TB），分布式数据管理（SDSC的4.1 TF和248 TB），远程渲染和可视化（阿贡国家实验室的1 TF和31 TB）。数据密集型科学应用分析（加州理工学院为0.4 TF和93 TB）。统一的运营中心将协调管理、用户支持和访问。DTF TeraGrid将对计算科学界产生广泛的影响，并最终使整个社会受益。首先，TeraGrid将通过向学术研究人员提供下一代信息技术来推进发现和促进理解，这些信息技术的能力比现在普遍可用的信息技术强一个数量级。其次，TeraGrid将通过其对商品集群、通用使用模型和社区代码的关注，赋予广泛的科学和工程社区权力。第三，通过DTF操作获得的经验、见解和来自TeraGrid的软件将打包在一系列软件发行版中供社区使用。该软件包将把TeraGrid技术扩展到更广泛的国家社区，包括少数民族服务机构（MSI）和EPSCoR机构。

The University of Illinois, Urbana-Champaign, in collaboration with University of California, San Diego, is funded by a Cooperative Agreement from the Division of Advanced Computational Infrastructure in the amount of $26,450,500 to construct a Distributed Terascale Facility (DTF) that will span four institutions: 1) National Center for Supercomputing Applications, 2) San Diego Supercomputer Center, 3) Argonne National Laboratory and 4) California Institute of Technology. In partnership with IBM, Intel, Myrinet, Qwest, Oracle and SUN, they will construct a DTF based on multiple terascale Linux clusters, as well as large-scale storage archives and data management software. A 40 gigabit/second optical mesh will interconnect the DTF's components. The DTF hardware will be integrated, using Globus middleware and other Computational Grid technologies develop by the Partnerships for Advanced Computational Infrastructure (PACI), to create a system with an aggregate of 11.6 TF of computing capability and 525 TB of disk storage to support terascale computing (6.1 TF and 153 TB at NCSA), distributed data management (4.1 TF and 248 TB at SDSC), remote rendering and visualization (1 TF and 31 TB at Argonne), and data-intensive scientific application analysis (0.4 TF and 93 TB at Caltech). A unified Operations Center will coordinate management, user support, and access. The DTF TeraGrid will have broad impact on the computational science community and will ultimately benefit society as a whole. First, the TeraGrid will advance discovery and promote understanding by making available to academic researchers next generation information technologies that are an order of magnitude more capable than now generally available. Second, the TeraGrid will empower broad scientific and engineering communities through its focus on commodity clusters, common usage models and community codes. Third, experience gained through DTF operation, insights and software from the TeraGrid will be packaged in a series of software distributions for community use. This software packaging will extend TeraGrid technologies to the broader national community, including Minority Serving Institutions (MSI) and EPSCoR Institutions.
