CC* Compute: A Cost-Effective, 2,048 Core InfiniBand Cluster at UTC for Campus Research and Education

田纳西大学查塔努加分校（UTC）的一组研究人员将对校园网络基础设施进行重大升级，以提供以前不可能实现的最先进、经济高效的高性能计算。该项目将显著提高大学研究人员和学生执行、增强和扩展其当前计算密集型研究、原型设计和开发活动的能力，并将补充UTC已经进行、正在进行或计划记录的其他投资，包括获得商业云计算服务。除了计算机科学和工程之外，联合技术大学团队预计将在数学、水文学和计算流体动力学方面开展重要的研究项目，这将与四所区域合作大学合作。两个教学项目涉及HPC教育和HPC在机械工程本科研究/设计中的应用。除了这些资助的项目之外，随着时间的推移，随着pi、Central IT和集群顾问委员会吸引更多需要高性能计算的研究人员和学生，有价值的其他研究项目也将得以实现。其他用户包括20多名计算科学博士生和几名博士后。此外，SimCenter——UTC的研究计算中心——通过HPC的自筹资金和REU支持本科生研究，为拟议的集群提供额外的用户。该合同允许田纳西大学查塔努加分校（UTC）采购一个创新的、2,048个计算核心、16台服务器的AMD EPYC2集群，该集群具有100Gbit/s InfiniBand、8TB主存和77 Tflop/s双精度浮点运算。EPYC2 Rome 7nm处理器将在性能期开始或接近开始时推出，因此该项目包括最先进的，具有成本效益的高性能计算，这是以前使用英特尔或AMD处理器无法实现的。这所大学最近在三年前投资了一个“商品”集群，它被现有的用户群大量利用。该系统将在本提议拨款开始时使用近四年。作为补充，升级到存储（1.1PB）、内部网络、数据中心基础设施和私有云虚拟化（将于2019年年中上线）使UTC准备好支持一个新的校园范围内的集群，除了这里提到的用户之外，用户数量也在不断增加。拟议中的新校园集群将支持以前在校园中不可用的核心规模和总集群内存，从而帮助研究人员准备在国家资源（如XSEDE）上进行更大规模的可扩展问题场景。立项项目14个，其中科研项目12个，教学项目2个。七个项目涉及四所区域伙伴大学。UTK、UTC、UAB、田纳西理工大学和密西西比大学的至少10项NSF资助得到了加强。重点项目领域包括容错并行计算、高性能计算性能监测、下一代MPI并行编程、专用线性代数、水文学和计算流体动力学研究。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

A team of researchers at the University of Tennessee at Chattanooga (UTC) will make a significant upgrade to the campus cyberinfrastructure that will provide state-of-the-art, cost-effective high-performance computing not previously possible. This project will significantly improve university researchers' and students' ability to perform, enhance, and expand their current computationally-intensive research, prototyping, and development activities and will complement other investments already made, in-progress, or on the plan-of-record of UTC, including access to commercial cloud computing services. In addition to computer science and engineering, the UTC team anticipates significant research projects in mathematics, hydrology and computational fluid dynamics which will engage four regional partner universities. Two teaching projects address HPC education and use of HPC for mechanical engineering undergraduate research/design. In addition to these funded projects, merited additional research projects are enabled over time as the PIs, Central IT, and the cluster's Advisory Board attract and onboard additional researchers and students requiring HPC. Among other users are the more than 20 computational science Ph.D. students, plus several postdocs. Furthermore, SimCenter---UTC's research computing hub---supports undergraduate research through self-funding and REU in HPC, providing additional users for the proposed cluster. This award allows the University of Tennessee at Chattanooga (UTC) to procure an innovative, 2,048-compute core, 16-server AMD EPYC2 cluster networked with 100Gbit/s InfiniBand plus 8TB of main memory and 77 Tflop/s of double-precision floating point arithmetic. EPYC2 Rome 7nm processors will be newly available at or near the start of the period of performance, so this project includes state-of-the-art, cost-effective, high-performance computing not previously possible using Intel or AMD processors. The university has invested in a "commodity" cluster as recently as three years ago, and it is heavily utilized by the existing user base. This system will be nearly four years old by the beginning of this proposed grant. By way of complement, upgrades to storage (1.1PB), internal networking, data center infrastructure, and private cloud virtualization (coming online by mid-2019) have prepared UTC to support a new campus-wide cluster with a growing number of users in addition to those named here. The proposed new campus cluster will enable core scales and total cluster memory not previously available on campus and thus help researchers prepare their scalable problem scenarios for greater scales on national resources such as XSEDE. Projects enabled immediately are 14 science driver projects (12 research, two teaching). Seven projects involve four regional partner universities. At least ten NSF grants at UTK, UTC, UAB, Tennessee Tech, and Ole Miss are enhanced. Project areas highlighted include fault-tolerant parallel computing, performance monitoring of HPC, next-generation parallel programming with MPI, special-purpose linear algebra, hydrology, and computational fluid dynamics research.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.
