Category I: Stampede3 -- Modernizing and Evolving The Largest ACCESS Compute Resource

计算，用于模拟或数据分析，是国家科学基金会支持的所有工程和科学领域的基本推动因素。Stampede和Stamecid2项目部署了非常成功的超级计算机，为NSF资助的数千个项目提供了数十亿小时的计算机处理时间，使人们能够在不同领域获得关键见解，从设计最新的药物发现到研究最早的星系和超大质量黑洞的形成。德克萨斯大学奥斯汀分校的德克萨斯高级计算中心(TACC)的这项提案将延续Stampede的传统，并部署一个新的综合超级计算环境，采用最新的处理器和加速器以及高带宽存储技术。在对科学计算最重要的许多方面，Stampede 3系统节点的性能将是目前Stampede 2节点的四倍多：计算能力、内存带宽和容量以及网络带宽。Expede 3不仅将服务于当今的研究人员，还将使社区继续朝着多核处理器和加速技术的发展道路前进，使社区为下一代超级计算机系统做好更好的准备。Exampede 3是围绕英特尔的Xeon Max处理器设计的，具有高带宽内存和少量Xeon Max GPU，同时还利用了最新的Stampede 2硬件的一部分。Stapede 3将为当今所有用户保持熟悉的编程模型，因此将广泛适用于传统模拟用户、执行数据密集型计算的用户以及新兴类别的新用户。该项目将延续戴尔、英特尔和TACC之间的成功合作伙伴关系。TACC及其合作伙伴在为科学界运营大规模计算系统方面拥有无与伦比的专业知识。除了支持该系统外，该项目还将继续提供全天候运行和熟悉广泛科学应用的高性能计算专家提供的卓越支持。在其一生中，Stampede 3将成为全国10,000+名科学家和工程师的关键大型研究工具，提供突破性创新，并成为数千名年轻研究人员大规模掌握计算工程和科学技能的平台。该系统将于2023年下半年部署，计划从2024年初运行到2029年初。该奖项反映了NSF的法定使命，通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Computing, for simulation or data analysis, is a fundamental enabler of all fields of engineering and science supported by the National Science Foundation. The Stampede and Stampede2 projects deployed enormously successful supercomputers that have delivered billions of processor hours of computer time to thousands of NSF funded projects, enabling key insights in diverse areas, from engineering the latest drug discoveries to studying the formation of the earliest galaxies and supermassive black holes. This proposal from the Texas Advanced Computing Center (TACC) at The University of Texas at Austin will continue the Stampede legacy and deploy a new comprehensive supercomputing environment with the latest processors and accelerators with high-bandwidth memory technologies. The Stampede 3 system nodes will be more than quadruple the performance of the current Stampede 2 nodes in many of the dimensions that are most important to scientific computing: computing capability, memory bandwidth and capacity, and network bandwidth. Stampede 3 will not only serve today’s researchers but will continue the community on an evolutionary path toward many-core processors and accelerated technologies, better preparing the community for the next generation of supercomputer systems. Stampede 3 is designed around Intel’s Xeon Max processors with high-bandwidth memory and a small number of Xeon Max GPUs, while also leveraging a portion of the most recent Stampede 2 hardware. Stampede 3 will maintain the familiar programming model for all of today’s users, and thus will be broadly useful for traditional simulation users, users performing data intensive computations, and emerging classes of new users.The project will continue the successful partnership between Dell, Intel, and TACC. TACC and its partners have unmatched expertise in operating large scale computing systems for the scientific community. In addition to supporting the system, the project will continue to offer 24x7 operations and superior support from High-Performance Computing experts familiar with a broad range of scientific applications. Through its lifetime, Stampede 3 will be a critical large scale research instrument for 10,000+ of the nation’s scientists and engineers, deliver groundbreaking innovation, and be a platform for thousands of young researchers to master computational engineering and science skills at scale. The system will be deployed in the second half of 2023 and is scheduled to operate from early 2024 until early 2029.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
