In 2016, the National Science Foundation funded the acquisition of a large new forward-looking high performance computing (HPC) system, Stampede 2, by the Texas Advanced Computing Center (TACC) at the University of Texas at Austin. In partnership with its lead system vendor (Dell), TACC will deploy the Intel-based system in 2017, doubling the capacity of its predecessor, Stampede, by introducing new memory, processor and interconnect technologies. As Stampede 2 nears its operational deployment, a proposal for operations and maintenance (O&M) of the system was submitted by the University of Texas at Austin. The system is expected to be used as a national resource by thousands of researchers, educators, and students annually. As a critical component of academic infrastructure, it will advance fundamental knowledge in a wide variety of science and engineering frontiers. In addition to continued partnership with Dell, subawards to Clemson University, The University of Colorado, Cornell University, Indiana University, and Ohio State University will ensure a broad national research of innovative HPC to academia and industry. Stampede 2 will operate within the larger landscape of the nation's research cyberinfrastructure (CI). It joins the set of large scale computing resources that rely on and benefit from the collaborative user services model of the NSF-funded Extreme Science and Engineering Discovery Environment (XSEDE) project. These accompanying shared services provide for systems allocations, user training, technical interoperability, research and CI community engagement, and access to expertise. Stampede 2 doubles the computing, storage and networking capacity of the current system, Stampede. Delivering on the potential of this complex scientific instrument requires knowledgeable and ongoing operations, which include: robust system maintenance, reliability and availability; security; software configuration and management; efficient utilization; and research workflow optimization. Most significantly, the thousands of users who currently depend on Stampede rely on expert assistance to help in the development of new skills in order to maximize the value of the new technologies in Stampede 2. These technologies represent the future of large-scale computing. The architecture of Stampede 2 reflects community consensus about HPC's exascale future; while specific technologies are in rapid flux, all paths indicate a transition to more explicit parallelism within applications. Today's applications must adapt, and Stampede 2 offers a bridge to exascale systems of tomorrow, providing capabilities for exploring new approaches to multiscale (both temporal and spatial) simulations, many forms of data intensive science, visualization, and data analysis. Stampede 2's operations will also broaden the usage base of HPC, appealing to and supporting a much greater depth and breadth of large-scale computational science for research than any other national system. The Stampede 2 Operations and Maintenance project plan includes world-class operations, user support and training, application tuning and migration, education, outreach, documentation, data management, visualization, analytics-driven application support, and research collaboration. TACC and its team of partners are established CI providers. Collectively the Stampede 2 operations team will leverage a variety of other NSF-supported projects such as XSEDE, Advanced Cyberinfrastructure Research and Education Facilitators (ACI-REF), and a broad array of scientific software activities. With these complementary collaborations, the value of the O&M award is further increased.

2016 年，美国国家科学基金会资助德克萨斯大学奥斯汀分校的德克萨斯高级计算中心 (TACC) 收购了大型新型前瞻性高性能计算 (HPC) 系统 Stampede 2。 TACC 与其领先系统供应商 (戴尔) 合作，将于 2017 年部署基于英特尔的系统，通过引入新的内存、处理器和互连技术，将其前身 Stampede 的容量提高一倍。随着 Stampede 2 接近其运营部署，德克萨斯大学奥斯汀分校提交了一份系统运营和维护 (O&M) 提案。 该系统预计每年将被数千名研究人员、教育工作者和学生用作国家资源。作为学术基础设施的重要组成部分，它将推进各种科学和工程领域的基础知识。除了与戴尔继续合作之外，向克莱姆森大学、科罗拉多大学、康奈尔大学、印第安纳大学和俄亥俄州立大学提供的子奖项将确保学术界和工业界对创新 HPC 进行广泛的全国性研究。 Stampede 2 将在国家研究网络基础设施 (CI) 的更大范围内运行。它加入了依赖于 NSF 资助的极限科学与工程发现环境 (XSEDE) 项目的协作用户服务模型并从中受益的大规模计算资源集。这些附带的共享服务提供系统分配、用户培训、技术互操作性、研究和 CI 社区参与以及专业知识的获取。 Stampede 2 将当前系统 Stampede 的计算、存储和网络容量提高了一倍。发挥这种复杂科学仪器的潜力需要知识渊博的持续运营，其中包括：强大的系统维护、可靠性和可用性；安全;软件配置和管理；高效利用；并研究工作流程优化。最重要的是，目前依赖 Stampede 的数千名用户依靠专家的协助来帮助开发新技能，以便最大限度地发挥 Stampede 2 中新技术的价值。这些技术代表了大规模计算的未来。 Stampede 2 的架构反映了社区对 HPC 百亿亿次计算未来的共识；虽然特定技术正在快速变化，但所有路径都表明应用程序内将过渡到更明确的并行性。当今的应用程序必须适应，Stampede 2 为未来的百亿亿次系统提供了一座桥梁，提供了探索多尺度（时间和空间）模拟、多种形式的数据密集型科学、可视化和数据分析的新方法的功能。 Stampede 2 的运营还将扩大 HPC 的使用基础，吸引并支持比任何其他国家系统更深入、更广度的大规模计算科学研究。 Stampede 2 运营和维护项目计划包括世界一流的运营、用户支持和培训、应用程序调整和迁移、教育、外展、文档、数据管理、可视化、分析驱动的应用程序支持和研究协作。 TACC 及其合作伙伴团队都是成熟的 CI 提供商。 Stampede 2 运营团队将共同利用 NSF 支持的各种其他项目，例如 XSEDE、高级网络基础设施研究和教育促进者 (ACI-REF) 以及广泛的科学软件活动。通过这些互补的合作，运维奖的价值进一步增加。
