CC* Regional Computing: Enhancing Computing At Regional Schools in the Rocky Mountain Advanced Computing Consortium (RMACC)

科罗拉多大学和落基山高级计算联盟(RMACC)的这个项目扩大了阿尔卑斯计算集群的能力，这是RMACC的一个地区性资源。该项目将容量扩展了15%以上，并将高内存节点的数量增加了两倍。支持范围广泛的研究，包括物理学、天文学、工程学、生物学和大气科学。该项目支持RMACC约30个成员机构的各种工作量。学生参与度很高，因为来自RMACC地区的10名学生是与系统管理团队密切合作的团队的一部分，以学习如何在系统的设计、采购、部署和管理中导航。该项目支持EPSCoR辖区的研究人员，主要是本科生机构、西班牙裔服务机构和RMAC内主要服务农村社区的机构。截至2023年2月，阿尔卑斯山集群由18,080个AMD米兰CPU核心以及60个GPU加速器(36xNVIDIA A100‘S，24xAMD MI100’S)组成。317个节点通过25 Gb以太网互连，标准计算节点还具有HDR100 InfiniBand链路。阿尔卑斯还配备了1.9PB的GPFS暂存文件系统。此次扩展包括32个节点的64C AMD米兰CPU和256 GB内存，以及8个节点的64C AMD米兰CPU和1TB内存。它还包括两个InfiniBand交换机和用于高吞吐量、低延迟网络的相关HDR电缆。此次扩建将为阿尔卑斯山的高速暂存文件系统提供额外的1.3PB空间，以满足日益增长的数据密集型计算研究需求。这一奖项反映了NSF的法定使命，并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。

This project to the University of Colorado and partners in the Rocky Mountain Advanced Computing Consortium (RMACC) expands the capacity of the Alpine Computing Cluster, a regional resource for RMACC. The project expands capacity by more than 15% and triples the number of high-memory nodes. A wide range of research is supported, including physics, astronomy, engineering, biology, and atmospheric science. The project supports diverse workloads for the approximately 30 member institutions of RMACC. Student engagement is strong, as ten students from across the RMACC region are part of a cohort working closely with the system administration team to learn how to navigate the design, procurement, deployment, and administration of the system. The project supports researchers in EPSCoR jurisdictions, at Primarily Undergraduate Institutions, Hispanic Serving Institutions, and institutions primarily serving rural communities within RMACC.As of February 2023, the Alpine cluster comprises 18,080 AMD Milan CPU cores as well as 60 GPU accelerators (36xNVIDIA A100’s, 24xAMD MI100’s). The 317 nodes are interconnected through 25Gb Ethernet, with standard compute nodes additionally featuring HDR100 InfiniBand links. Alpine is also equipped with a 1.9PB GPFS scratch filesystem. The expansion includes 32 nodes of 64C AMD Milan CPUs and 256GB of memory as well as eight nodes with 64C AMD Milan CPUs and 1TB of memory. It also includes two InfiniBand switches and associated HDR cables for high-throughput, low-latency networking. The expansion will provide an additional 1.3PB to Alpine’s high-speed scratch filesystem to meet the growing demand for data intensive computing 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.
