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的延续和发展：极端科学与工程发现环境。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，以及扩大他们在科学和工程领域的参与，来加速开放的科学发现。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、强大的服务中，并建立用户和提供者社区来实现这一目标。XSEDE是一个虚拟组织，它提供复杂的分布式基础设施、支持服务和技术专长。对于XSEDE来说，一个突出的机会是高级计算、高端可视化、数据分析和其他可供研究人员、工程师和学者使用的资源和服务的不断增长的多样化集合；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。挑战还包括促进对充分利用XSEDE及其相关资源所提供的能力的认识和培训，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策略来完成。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）的合作组织的共同PI和工作人员执行。德克萨斯大学奥斯汀分校)，以及其他15个合作组织。在接下来的五年里，为了追求提高用户生产力和扩大CDS&amp；E社区参与的总体目标，XSEDE 2将提供一个适应性和流线化的框架，预测技术进步所提供的机会，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。与最初的XSEDE项目相比，三个战略目标保持不变：*深化和扩展现有计算研究人员和新的科学家和学生社区对国家网络基础设施（CI）生态系统的使用，计算和大规模数据的使用正在改变他们各自的领域；*通过创建一个开放和不断发展的基础设施，并通过加强一系列技术专长和提供的支持服务，推进国家CI生态系统；*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，将提供一个更灵活和响应更快的计划，旨在加速实现战略目标：*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、评估和授予计算资源建议的过程。这样，它将履行XSEDE 2在将资源从服务提供商生态系统分配给研究社区方面的中立仲裁者的关键角色。RAS还将通过增加透明度、公开报告用户趋势和使分配过程适应新技术，确定分配创新的新机会。*修订后的XSEDE社区基础设施（XCI）服务，由康奈尔大学和其他六个合作伙伴领导，将识别、评估、测试和提供新的软件功能。治理到位，以确保这些活动是由网络基础设施的用户和提供者的需求驱动的。*社区参与和充实（CEE），由德克萨斯大学和其他12个合作伙伴领导，将建立在XSEDE优秀用户服务的传统上，并吸引新一代不同的计算研究人员。除了教育、培训和推广活动外，CEE还将与校园HPC社区建立联系，帮助研究人员获得当地和国家的资源。*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）将通过其大量的计算专家人员，最大限度地提高高性能计算资源的效率，这些计算专家将直接参与研究团队，为科学项目提供先进的援助。*最后，由田纳西大学和其他五个合作伙伴领导的XSEDE运营将维持和发展国家规模的集成HPC能力。Operations为跨xsede协调的HPC生态系统的用户提供了“一站式”体验。虽然继续提供这些服务对于庞大和进一步增长的用户社区至关重要，但XSEDE 2也将响应科学和技术不断变化的需求和机会。为此，XSEDE 2将开发与其他国家、地区和校园网络基础设施组织连接和合作的新方法。该项目将继续创新使用“电子科学门户”（也称为科学门户）。科学网关为科学领域提供定制的接口和服务，并在设施和研究中心中发挥越来越大的作用，在大型研究项目中进行合作（例如，Advanced LIGO, Polar Geospatial Center）。这种方法促进了广泛的社区对高级计算和数据资源的访问。科学网关现在为超过50%的用户社区提供服务。XSEDE 2还将纳入新的方法，为对云计算资源和大数据项目感兴趣的用户提供服务。此外，通过分析使用和技术的趋势，更新项目将更好地响应其利益相关者不断变化的需求，以及在新的计算和数据资源中出现的机会。
