The Extensible Terascale Facility (ETF) is the next stage in the evolution of NSF large-scale cyberinfrastructure for enabling high-end computational research. The ETF enables researchers to address the most challenging computational problems by utilizing the integrated resources, data collections, instruments and visualization capabilities of nine resource partners. On October 1, 2004, the ETF concluded a three-year construction effort to create this distributed environment called the TeraGrid (TG) and we are now entering the production operations phase.The TeraGrid resource partners include: the University of Chicago/Argonne National Laboratory, the San Diego Supercomputer Center at UCSD, the Texas Advanced Computing Center at UT-Austin, the National Center for Supercomputing Applications at UIUC, Indiana University, Purdue University, Oak Ridge National Laboratory, and the Pittsburgh Supercomputing Center.A separate proposal was submitted to NSF on October 19, 2004 for the TeraGrid Grid Infrastructure Group (GIG). Under the direction of Charlie Catlett at UC/ANL, in general, the GIG will be responsible for coordination of development activities for the TeraGrid with subcontracts to the partner sites. The resource partners (RP) will each have independent cooperative agreements with NSF, but will work closely with the GIG to implement the vision of the TeraGrid.This proposal outlines the plan at SDSC to participate as a resource partner in the TeraGrid team to provide the expanding user community with ongoing access to this computational science facility. This proposal covers the period November 1, 2004 through October 31, 2009.SDSC will bring a powerful set of compute and storage resources to the TeraGrid and will focus on the data-intensive computing needs of TeraGrid scientists. SDSC's current TeraGrid resources are summarized with those of other RP sites and include a 3.1 Tflop IA- 64 system, a 1.1 Tflop Power4 system (part of the larger DataStar system), and an experimental 1.3 Tflop IA-64 system. Every SDSC compute node can access data at 200 MBps or more and can use its DB2 client to address structured databases via leading edge servers. The central Storage Area Network (SAN) has over 0.5 PB of disk and a 6 PB archival tape capacity available to all nodes and servers, and SDSC plans to export its capabilities across the TeraGrid Wide Area Network (WAN) [16, 17] using a true global file system. SDSC's 540 TB SAN of online disk will make possible new modes of handling data across the TeraGrid. Generating data locally, competing with others for disk space and saving results to archival storage through an often slow interface all serve as restrictions to scientists. The ability to write directly to a very large file system, where post-processing can occur and where results are automatically archived, is a significant improvement in capability for scientists. For example, the Southern California Earthquake Center (SCEC) [6] has performed an earthquake simulation analyzing the resulting damage from a potential earthquake in the Southern California region.

可扩展Terascale设备(ETF)是NSF大规模网络基础设施发展的下一个阶段，用于支持高端计算研究。ETF使研究人员能够通过利用九个资源合作伙伴的集成资源、数据收集、仪器和可视化能力来解决最具挑战性的计算问题。2004年10月1日，ETF完成了一项为期三年的构建工作，以创建这种名为TeraGrid(TG)的分布式环境，我们现在正在进入生产运营阶段。TeraGrid的资源合作伙伴包括：芝加哥大学/阿贡国家实验室、加州大学圣地亚哥分校的圣地亚哥超级计算机中心、德克萨斯大学奥斯汀分校的德克萨斯高级计算中心、加州大学洛杉矶分校的国家超级计算应用中心、印第安纳大学、普渡大学、橡树岭国家实验室和匹兹堡超级计算中心。TeraGrid基础设施组(GIG)的单独提案已于2004年10月19日提交给NSF。在UC/ANL的Charlie Catlett的指导下，一般而言，GIG将负责协调TeraGrid的开发活动，并将分包合同转给合作伙伴网站。资源合作伙伴(RP)将各自与NSF签订独立的合作协议，但将与GIG密切合作，以实现TeraGide的愿景。该提案概述了SDSC作为TeraGrid团队的资源合作伙伴参与的计划，以向不断扩大的用户社区提供对这一计算科学设施的持续访问。SDSC将为TeraGrid带来一组强大的计算和存储资源，并将重点放在TeraGrid科学家的数据密集型计算需求上。SDSC目前的TeraGrid资源与其他RP站点的资源进行了总结，包括3.1Tflp IA-系统、1.1Tflp Power4系统(更大的DataStar系统的一部分)和试验性1.3Tflp IA-系统。每个SDSC计算节点都可以200 Mbps或更高的速度访问数据，并且可以使用其DB2Client通过领先的服务器寻址结构化数据库。中央存储区域网络(SAN)拥有超过0.5 PB的磁盘和6 PB的存档磁带容量，可供所有节点和服务器使用，SDSC计划使用真正的全球文件系统跨TeraGrid广域网(WAN)[16、17]输出其功能。SDSC的540 TB SAN在线磁盘将使跨TeraGrid处理数据的新模式成为可能。在本地生成数据，与其他人争夺磁盘空间，以及通过通常速度较慢的界面将结果保存到档案存储中，这些都对科学家构成了限制。对于科学家来说，能够直接写入非常大的文件系统(可以在其中进行后处理并将结果自动存档)是一项重大的能力改进。例如，南加州地震中心(SCEC)[6]进行了一次地震模拟，分析了南加州地区潜在地震造成的损害。
