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的延续和演变：极端的科学与工程发现环境。 XSEDE的目的是通过提高研究人员，工程师和学者的生产率和能力，并扩大他们对科学和工程的参与来加速开放科学发现。它通过使高级计算资源更易于使用，将现有资源集成到新的，强大的服务并建立用户和提供商社区。 XSede是一个虚拟组织，可为复杂的分布式基础架构，支持服务和技术专长提供。 XSEDE的一个突出机会是研究人员，工程师和学者可获得的高级计算，高端可视化，数据分析以及其他资源和服务的潜水员收集；这些资源有可能帮助理解和解决国家和世界面临的最重要和挑战问题。作为虚拟组织，Xsede面临的挑战是组织这些不同的资源，创建集成服务和满足最终用户需求的协调环境。挑战还包括促进对XSede及其相关资源提供的功能的全面利用以及培训的认识和培训，以及催化劳动力发展。所有这些任务都需要根据不断发展的用户需求，资源和NSF策略来完成。XSEDE 2项目将由伊利诺伊州伊利诺伊州大学伊利诺伊大学乌尔巴纳 - 坎普大学（Urbana-Champaign）的首席研究员（PI）和国家超级计算应用中心（NCSA）的工作人员执行和匹兹堡大学），圣地亚哥超级计算中心（SDSC，加利福尼亚大学圣地亚哥分校）和德克萨斯州高级计算中心（TACC，德克萨斯大学奥斯汀大学）以及其他15个合作伙伴组织。在接下来的五年中，为了提高社区和ED型的整体范围，以实现其整体目标，以追求其整体目标，并将其提供适用于XSSSSED的机会。通过技术的进步，可以响应用户有效利用新功能的能力，并使当前和下一代使用这些技术可以推进其领域。与原始XSEDE项目相比，这三个战略目标仍然保持不变：*现有计算研究人员和科学家和学生的新社区都可以加深和扩展国家Cyber​​infrasture（CI）的生态系统（CI），其中计算和大规模数据的使用正在通过各自的CI生态系统来增强和促进技术范围；提供的支持服务； *和*通过维持安全，可靠和高效的基础架构来维持国家CI生态系统。XSEDE2将重组为五个目标驱动的重点领域，将提供一个更敏捷和响应式的计划，旨在加速战略目标：*资源分配服务（RAS），由RAS启用，由国家中心研究（RAS）启用，并将继续进行大气研究（NCAR）和其他零件，并将其授予其他零件（NCAR），并将其设置为nCAR和其他四个零件。有关计算资源的建议。通过这样做，它将履行Xsede 2中立仲裁者在将服务支持者生态系统分配给研究界的资源中的关键作用。 RAS还将通过提高透明度，用户趋势的开放报告以及将分配流程适应新技术的新机会。治理是为了确保这些活动是由用户和网络基础设施提供者的需求驱动的。除教育，培训和外展活动外，CEE还将连接到HPC校园，以帮助研究人员访问本地和国家资源。 *最终，由田纳西大学和其他五个合作伙伴领导的Xsede行动将维持和发展国家规模的HPC综合能力。操作为XSEDE协调的HPC生态系统的用户提供了“一站式”体验。在提供这些服务的连续性对于大型且较大的用户社区至关重要的时候，XSEDE 2还将负责科学和技术的不断发展的需求和机会。为此，Xsede 2将开发出与其他国家，地区和校园网络基础设施组织联系并合作的新颖方法。该项目将继续创新使用“电子科学门户”（也称为科学门户）。科学网关提供了针对领域科学定制的界面和服务，并在设施和研究中心中发挥了越来越多的作用，并在大型研究事业（例如，高级Ligo，Polar Geospatial Center）合作。这种方法设施广泛地访问了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还将结合新方法，以服务于对云计算资源和大数据项目有兴趣的用户。此外，通过分析用法和技术的趋势，续订项目将更好地适应其利益相关者不断发展的需求以及新的计算和数据资源的新兴机会。
