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门提供26,450,500美元的合作协议，以建设一个分布式Terascale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、英特尔、Myrinet、QWest、甲骨文和SUN合作，构建一个基于多个Terascale Linux集群的DTF，以及大规模存储档案和数据管理软件。40千兆位/秒的光网将互连DTF的组件。DTF硬件将使用Globus中间件和先进计算基础设施伙伴关系(PACI)开发的其他计算网格技术进行集成，以创建一个总计算能力为11.6 Tf和525 TB的磁盘存储系统，以支持兆级计算(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(Argonne的1 Tf和31 TB)以及数据密集型科学应用分析(Caltech的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，并最终造福于整个社会。首先，TeraGrid将通过向学术研究人员提供比目前普遍可用的能力高出一个数量级的下一代信息技术来推进发现和促进理解。其次，TeraGrid将通过其对商品集群、通用使用模式和社区代码的关注，增强广泛的科学和工程社区的能力。第三，通过DTF操作获得的经验、从TeraGrid获得的见解和软件将被打包成一系列软件分发，供社区使用。这一软件包装将把TeraGrid技术扩展到更广泛的国家社区，包括少数族裔服务机构(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.
