The Texas Advanced Computing Center (TACC) at the University of Texas at Austin will acquire and deploy Stampede 2, a new, nearly 20 petaflop High Performance Computing (HPC) system. This system will be available to and accessed by thousands of researchers across the country. It will enable new computational and data-driven scientific and engineering, research and educational discoveries and advances. As a national resource, Stampede 2 will replace and surpass the current highly successful Stampede system. The new system will deliver over twice the overall performance as the current system in many dimensions most important to scientific computing, including computing capability, storage capacity, and network bandwidth. TACC and its academic partners will team with Dell, Inc. and Intel Corp. to procure and provide this system. HPC is intrinsic to discovery across the science and engineering disciplines served by the NSF. This resource allows researchers to explore those scientific and engineer frontiers that require very large scale computations not otherwise possible. Over the life of Stampede 2, the system is expected to serve many thousands of researchers spanning all NSF-supported disciplines, as the current system has done. In addition to being an immediately productive resource for a large community of computational engineers and scientists, Stampede 2 will also continue the community on an evolutionary path to future "many core" computing technologies. Stampede 2 will employ upcoming generations of Intel's Xeon and Xeon Phi processors, as well as the Intel Omni-Path network fabric. The system will maintain a familiar Linux-based software environment to insure a smooth migration of the large existing user base to the new system. The system and its software stack will be designed to support traditional large scale simulation users, users performing data intensive computations, as well as emerging classes of new and non-traditional users to high performance computing. Stampede 2 will support breakthrough discoveries and advances across a wide range of research topics.

德克萨斯大学奥斯汀分校的德克萨斯高级计算中心(TACC)将购买和部署Stampede 2，这是一种新的、近20petaflop的高性能计算(HPC)系统。这个系统将向全国数千名研究人员开放和访问。它将使新的计算和数据驱动的科学和工程、研究和教育发现和进步成为可能。作为国家资源，Stampede 2将取代并超越目前非常成功的Stampede系统。新系统在许多对科学计算最重要的方面，包括计算能力、存储容量和网络带宽，将提供当前系统两倍以上的整体性能。TACC及其学术合作伙伴将与戴尔公司和英特尔公司合作采购和提供该系统。高性能计算是NSF所服务的科学和工程学科的内在发现。这一资源允许研究人员探索那些需要非常大规模的计算的科学和工程前沿，否则是不可能的。在Stampede 2的整个生命周期内，该系统预计将像目前的系统一样，为跨越NSF支持的所有学科的数千名研究人员提供服务。除了为计算工程师和科学家的大型社区提供即时的生产性资源外，Stampede 2还将继续使社区在未来的“多核心”计算技术的发展道路上前进。Exampede 2将采用即将推出的英特尔至强和至强Phi处理器，以及英特尔全路径网络结构。该系统将维持一个熟悉的基于Linux的软件环境，以确保现有的庞大用户群顺利过渡到新系统。该系统及其软件堆栈将被设计为支持传统的大规模模拟用户、执行数据密集型计算的用户以及新兴类别的新用户和非传统用户到高性能计算。《踩踏2》将在广泛的研究课题上支持突破性发现和进步。
