SCI: Teragrid Resource Partners

可扩展兆级设施（ETF）是NSF大规模网络基础设施发展的下一个阶段，旨在实现高端计算研究。ETF使研究人员能够利用9个资源合作伙伴的综合资源、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结束了为期三年的建设工作，创建了这个称为TeraGrid （TG）的分布式环境，我们现在正在进入生产操作阶段。TeraGrid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、UIUC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。2004年10月19日，美国国家科学基金会（NSF）为TeraGrid电网基础设施集团（GIG）提交了一份单独的提案。在UC/ANL的Charlie Catlett的指导下，GIG将负责协调TeraGrid的开发活动，并将分包合同分包给合作伙伴。资源合作伙伴（RP）将分别与NSF签订独立的合作协议，但将与GIG密切合作，以实现TeraGrid的愿景。该提案概述了PSC作为TeraGrid团队的资源合作伙伴参与的计划，为不断扩大的用户社区提供对该计算科学设施的持续访问。该提案涵盖2004年11月1日至2009年10月31日期间。TeraGrid是第一个将网格功能与自主开放的国家计算中心和大学的政策和程序完全集成的大型网格之一。随着我们从建设到运营，TeraGrid资源合作伙伴将与用户合作，确保TeraGrid提供方便、可靠、持久的功能，并促进一系列用户优先级，包括新的网格服务，如协同调度、元调度、参数搜索工具和数据管理和处理方面的进步，并实施和支持科学网关的各种工具和功能。PSC致力于TG的目标，即通过使用先进的IT能力促进美国研究人员的突破性科学。我们的高技能员工将继续在PSC长期卓越的许多领域为TG做出重大贡献，包括用户支持、系统、网络、安全和传播，并特别强调在NSF TG计划中创建领导级计算能力，以实施NSF HPC+X。策略。我们与国内许多最优秀的计算科学家建立了牢固、长期和持续的关系，这是我们提供服务和改进服务的方法的一个组成部分。我们通过增强他们的应用程序来利用非常大的并行计算资源，并通过部署和操作这些资源的最佳可用性来最大化他们的科学产出，从而支持他们的科学努力。我们专注于最苛刻的应用程序。在过去的六个月里，超过一半的TCS处理器时间用于使用至少1,024个处理器的作业。9月份，30%的工作至少使用了2,048个处理器。在过去的一年里，51个pi运行的作业至少需要1024个处理器。这些令人印象深刻的结果是通过我们对高端计算的用户需求的高度关注而实现的。这包括许多方面，包括与研究小组紧密联系的用户和应用程序支持人员，灵活和响应性调度以及仔细考虑的系统设计。这一重点很好地服务于社区，并将应用于不断扩大的TG工作。PSC已被选中安装、评估和操作一个新的原型系统，该系统有可能成为NSF项目的领导级资源。我们相信，我们对高端计算的持续关注和重视将为这一努力带来成功。我们热切期待有机会通过我们独特的能力和对TeraGrid的贡献来推进美国的科学和工程研究。该提案涵盖了支持、进一步开发和将我们的系统紧密集成为一个统一的资源的计划，以支持计算科学研究并将该资源集成到TG中，但它也涵盖了TG的进一步发展。此外，我们还描述了为支持分布式的、依赖于it的科学和工程研究的国家基础而日益有效地使用所有这些资源所需要的用户支持。我们涵盖了非常广泛的领域，从当地的PSC水平到全国分布的TG水平。下面规定的标题可能表明，每项活动都是独立的。事实上，PSC投入了相当大的努力来整合这些努力，以便更好地响应用户。在所有层面上，我们关注现有的能力，它们的持续增强和改进，将它们组装成一个整体，并努力使整个整体响应客户、科学和工程研究界的需求。我们的活动效率很高。我们的员工和预算比其他具有同等责任的组织要少得多。在某种程度上，这是通过有针对性地开发新技术方法来实现的，而不是接受为具有不同需求的企业设计的成本更高的商业产品。

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 PSC 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.The TeraGrid is one of the first large-scale grids to fully integrate grid capabilities with the policies and procedures of both autonomous open national computing centers and universities. As we move from construction to operation, the TeraGrid resource partners will work with users to ensure that TeraGrid is delivering the promise of convenient, reliable, persistent capabilities, and to promote a set of user priorities that include new Grid services such as co-scheduling, meta scheduling, parameter search tools and advances in data management and handling, and to implement and support a variety of tools and capabilities for science gateways. The PSC is dedicated to the TG goal of promoting breakthrough science by U.S. researchers through the use of advanced IT capabilities. Our highly skilled staff will continue to make substantial contributions to TG in many areas of long-standing PSC excellence including user support, systems, networking, security and dissemination and with particular emphasis on the creation of a leadership class computing capability, within the NSF TG program, to implement the NSF HPC+X. strategy. Our strong, longstanding and ongoing relationships with many of the best computational scientists in the country are an integral part of our approaches both to provide service and to improve that service. We support their scientific endeavors by enhancing their applications to exploit very large parallel computing resources and by deploying and operating the best available of these resources to maximize they're scientific OutputWe focus on the most demanding applications. For the past six months, more than half of the TCS processor hours delivered was for jobs using at least 1,024 processors. For the month of September, 30% of the work used at least 2,048 processors. Over the past year fifty-one PIs ran jobs which required at least 1,024 processors. These impressive results are achieved through our intense focus on the user requirements for high-end computing. This has many aspects including user and applications support staff tightly associated with the research groups, flexible and responsive scheduling and carefully considered systems design. This focus has served the community well and will be applied to the expanding TG efforts. PSC has been selected to install, evaluate and operate a new prototype system, which has the potential to become a Leadership Class resource for the NSF program. We are confident that our continued concentration and emphasis on high-end computing will bring success to this endeavor. We eagerly anticipate the opportunity to advance U.S. Scientific and engineering research through our unique capabilities and contributions to the TeraGrid. This proposal covers plans for the support, further development, and tight integration of our systems into a unified resource for the support of computational science research and the integration of that resource into the TG but it also covers the further development of the TG. In addition, we describe the user support required for the growing productive use of all these resources in support of the distributed, national base of IT-dependent research in science and engineering. We cover this very broad ground starting from the local PSC level and working to the national, distributed TG level. The prescribed headings that follow may suggest that each of the activities stands on its own. In fact, PSC devotes considerable effort to integrating these efforts to be more responsive to users. At all levels, we address the existing capabilities, their continual augmentation and improvement, their assembly into an integrated whole and the efforts required to make that whole responsive to the needs of the client, the scientific and engineering research communities. Our activities are highly efficient. Our staff and budget are significantly smaller than other organizations with comparable responsibilities. In part, this is achieved by targeted development of new technology approaches rather than accepting higher-cost commercial offerings designed for enterprises with different requirements.
