This award supports the continuation and evolution of NSF project 1053575 - XSEDE: eXtreme Science and Engineering Discovery Environment. The goal of XSEDE is to accelerate open scientific discovery by enhancing the productivity and capability of researchers, engineers, and scholars, and by broadening their participation in science and engineering. It does so by making advanced computational resources easier to use, integrating existing resources into new, powerful services and building the community of users and providers. XSEDE is a virtual organization that provisions complex distributed infrastructure, support services, and technical expertise. A prominent opportunity for XSEDE is the growing, diverse collection of advanced computing, high-end visualization, data analysis, and other resources and services available to researchers, engineers, and scholars; these resources have the potential to help understand and solve the most important and challenging problems facing the nation and world. The challenge for XSEDE, as a virtual organization, is to organize these disparate resources, creating integrated services and a coordinated environment that serves the end user needs. The challenge also includes fostering awareness of, and training for, full utilization of the capabilities offered by XSEDE and its associated resources, as well as catalyzing workforce developments. All these tasks need to be accomplished in light of evolving user requirements, resources, and NSF strategies.The XSEDE 2 project will be executed by the principal investigator (PI) and staff of the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign and by the co-PIs and staff of the partner organizations at the Pittsburgh Supercomputing Center (PSC, Carnegie Mellon University and University of Pittsburgh), San Diego Supercomputing Center (SDSC, University of California San Diego), and Texas Advanced Computing Center (TACC, University of Texas at Austin), as well as 15 other partner organizations.For the next five years, in pursuit of its overall goals of enhancing user productivity and broadening participation of the CDS&E community, XSEDE 2 will provide an adaptive and streamlined framework that anticipates the opportunities afforded by advances in technology, responds to users' abilities to make effective use of new capabilities, and enables the current and next generation in using these technologies to advance their fields. The three strategic goals remain unchanged from the original XSEDE project:* To deepen and extend use of the ecosystem of national cyberinfrastructure (CI) by both existing computational researchers and new communities of scientists and students where the use of computation and large-scale data is transforming their respective fields;* To advance the national CI ecosystem by creating an open and evolving infrastructure, and by  enhancing the array of technical expertise and support services offered; and* To sustain the national CI ecosystem by maintaining a secure, reliable and efficient infrastructure.XSEDE 2 will reorganize into five goal-driven focus areas that will provide a more agile and responsive program designed to accelerate progress toward the strategic goals:* The Resource Allocation Service (RAS), led by the National Center for Atmospheric Research (NCAR) and four other partners, will continue to manage the process of receiving, evaluating and awarding proposals for computational resources. In doing so, it will fulfill XSEDE 2's crucial role of neutral arbiter in allocating resources from the service-provider ecosystem to the research community. RAS will also identify new opportunities for allocation innovations by increased transparency, open reporting of user trends, and adapting the allocation process to new technologies.* The revised XSEDE Community Infrastructure (XCI) service, led by Cornell University and six other partners, will identify, evaluate, test, and make available new software capabilities. Governance is in place to ensure that these activities are driven by the needs of both users and providers of cyberinfrastructure.* Community Engagement & Enrichment (CEE), led by the University of Texas and 12 other partners, will build on the XSEDE tradition of outstanding user services, and engage a new generation of diverse computational researchers. In addition to education, training, and outreach activities, CEE will connect to campus HPC communities, to help researchers access both local and national resources.* The Extended Collaborative Support Service (ECSS), led by the San Diego Supercomputer Center, the Pittsburgh Supercomputing Center and eight other partners, will maximize the effectiveness of HPC resources through its large staff of computational experts who will directly participate in research teams, providing advanced assistance to science projects.* Finally, XSEDE Operations, led by the University of Tennessee and five other partners, will maintain and evolve an integrated HPC capability of national scale. Operations provides a "one-stop-shop" experience for users across the XSEDE-coordinated HPC ecosystem.While continuity in providing these services is essential for the large and further-growing user community, XSEDE 2 will also respond to the evolving needs and opportunities of science and technology. To this end, XSEDE 2 will develop novel ways to connect to and collaborate with other national, regional and campus cyberinfrastructure organizations. The project will continue to innovate the use of "e-science portals" (also known as Science Gateways). Science gateways provide interfaces and services that are customized to a domain science and have an increasing role with facilities and research centers, collaborating on large research undertakings (e.g., Advanced LIGO, Polar Geospatial Center). This approach facilitates broad community access to advanced compute and data resources. Science gateways are now serving more than 50% of the user community. XSEDE 2 will also incorporate new methods to serve users interested in cloud computing resources and big-data projects. Furthermore, by analyzing trends in usage and technology, the renewal project will be even better positioned to respond to the evolving needs of its stakeholders and to emerging opportunities in new compute and data resources.

该奖项支持 NSF 项目 1053575 - XSEDE：极限科学与工程发现环境的延续和发展。 XSEDE 的目标是通过提高研究人员、工程师和学者的生产力和能力以及扩大他们对科学和工程的参与来加速开放科学发现。它通过使先进的计算资源更易于使用、将现有资源集成到新的、强大的服务以及建立用户和提供商社区来实现这一目标。 XSEDE 是一个虚拟组织，提供复杂的分布式基础设施、支持服务和技术专业知识。 XSEDE 的一个重要机会是为研究人员、工程师和学者提供不断增长、多样化的高级计算、高端可视化、数据分析以及其他资源和服务；这些资源有潜力帮助理解和解决国家和世界面临的最重要和最具挑战性的问题。作为一个虚拟组织，XSEDE 面临的挑战是组织这些不同的资源，创建满足最终用户需求的集成服务和协调环境。该挑战还包括培养对 XSEDE 及其相关资源提供的能力的充分利用的认识和培训，以及促进劳动力发展。所有这些任务都需要根据不断变化的用户需求、资源和 NSF 战略来完成。XSEDE 2 项目将由伊利诺伊大学厄巴纳-香槟分校国家超级计算应用中心 (NCSA) 的首席研究员 (PI) 和工作人员以及匹兹堡超级计算中心（PSC、卡内基梅隆大学）的合作伙伴组织的联合 PI 和工作人员执行 和匹兹堡大学）、圣地亚哥超级计算中心（SDSC，加州大学圣地亚哥分校）和德克萨斯高级计算中心（TACC，德克萨斯大学奥斯汀分校）以及其他 15 个合作伙伴组织。在未来五年中，为了实现提高用户生产力和扩大 CDS&E 社区参与的总体目标，XSEDE 2 将提供一个自适应且简化的框架，该框架可预测所提供的机会 通过技术进步，响应用户有效利用新功能的能力，并使当前和下一代能够使用这些技术来推进他们的领域。三个战略目标与最初的 XSEDE 项目保持不变：* 现有的计算研究人员和新的科学家和学生社区加深和扩展对国家网络基础设施 (CI) 生态系统的使用，其中计算和大规模数据的使用正在改变各自的领域；* 通过创建开放和不断发展的基础设施，并通过增强一系列技术专业知识和能力来推进国家网络基础设施生态系统的发展。 提供的支持服务； * 通过维护安全、可靠和高效的基础设施来维持国家 CI 生态系统。XSEDE 2 将重组为五个目标驱动的重点领域，这些领域将提供更加灵活和响应迅速的计划，旨在加速实现战略目标的进展：* 由国家大气研究中心 (NCAR) 和其他四个合作伙伴领导的资源分配服务 (RAS) 将继续管理接收、评估和授予的流程 计算资源的建议。在此过程中，它将履行 XSEDE 2 作为中立仲裁者的关键角色，将资源从服务提​​供商生态系统分配给研究社区。 RAS 还将通过提高透明度、公开报告用户趋势以及根据新技术调整分配流程来发现分配创新的新机会。*由康奈尔大学和其他六个合作伙​​伴领导的修订后的 XSEDE 社区基础设施 (XCI) 服务将识别、评估、测试并提供新的软件功能。治理到位，以确保这些活动是由网络基础设施用户和提供商的需求驱动的。*由德克萨斯大学和其他 12 个合作伙伴领导的社区参与和丰富 (CEE) 将建立在 XSEDE 出色的用户服务传统之上，并吸引新一代多元化的计算研究人员。除了教育、培训和外展活动外，CEE 还将连接校园 HPC 社区，帮助研究人员获取本地和国家资源。* 由圣地亚哥超级计算机中心、匹兹堡超级计算中心和其他八个合作伙伴领导的扩展协作支持服务 (ECSS) 将通过直接参与研究团队的大量计算专家，最大限度地提高 HPC 资源的有效性，为科学提供先进的帮助 * 最后，由田纳西大学和其他五个合作伙伴领导的 XSEDE Operations 将维护和发展国家规模的综合 HPC 能力。运营为 XSEDE 协调的 HPC 生态系统中的用户提供“一站式”体验。虽然提供这些服务的连续性对于庞大且进一步增长的用户社区至关重要，但 XSEDE 2 还将响应科学技术不断变化的需求和机遇。为此，XSEDE 2 将开发新的方法来与其他国家、地区和校园网络基础设施组织进行联系和协作。该项目将继续创新“电子科学门户”（也称为科学网关）的使用。科学网关提供针对领域科学定制的接口和服务，并在设施和研究中心中发挥越来越大的作用，在大型研究事业上进行合作（例如，高级 LIGO、极地地理空间中心）。这种方法有助于广泛的社区访问高级计算和数据资源。科学网关现在为超过 50% 的用户社区提供服务。 XSEDE 2还将融入新的方法来服务对云计算资源和大数据项目感兴趣的用户。此外，通过分析使用和技术的趋势，更新项目将能够更好地响应利益相关者不断变化的需求以及新计算和数据资源中的新机遇。
