This proposal is to fund the Isambard 3 Tier-2 national HPC service from the GW4 Alliance universities of Bristol, Bath, Cardiff and Exeter.Isambard 3 will follow on from the successful Isambard 1 & 2 projects, delivering a supercomputer service based on the increasingly important Arm architecture. Isambard 3 will employ NVIDIA's new 'Grace' Arm-based processors, due out in early 2023, to build a fast yet highly energy efficient service. Isambard 3 will be moving into its own dedicated facility, hosted by the University of Bristol. This new facility, homed within a new modular data centre, will for the first time employ direct liquid cooling to the processors, reducing the total amount of energy used for cooling the system, and creating the opportunity to extract and use the waste heat. We expect to procure a system of at least 6 racks, 55,000 cores, which should be large enough to rank in the Top500 list of supercomputers at SC in Nov 2023. Isambard 3 will also continue to provide a Multi Architecture Comparison System, or MACS, which will includes 2-4 nodes of every important new CPU and GPU architecture to be released during the 4 year lifetime of the Isambard 3 service. This will enable scientifically rigorous architectural comparisons between Arm and the latest CPUs and GPUs from Intel, AMD, NVIDIA, and other emerging providers.The Isambard 3 service will feature an expanded support team compared to previous services, including 6 RSEs and 2 systems administrators on the technical support side, as well as 0.5 FTE of project manager, and a business development manager on the user community engagement and development side. In summary, the successful Isambard Arm-based Tier-2 service will be expanding to support a much wider user community across all of UKRI, with the first Arm-based server CPUs optimised specifically for HPC from a top-tier silicon vendor. It will be one of the first such systems anywhere in the world, and deliver one of the most energy efficient, low carbon, general purpose CPU services available. The Grace processors should be amongst the fastest available for Isambard's user community, which we expect to expand into weather and climate applications, as well as life sciences and beyond.

该提案是为布里斯托尔、巴斯、卡迪夫和埃克塞特的GW4联盟大学的Isambard 3 Tier-2国家高性能计算服务提供资金。Isambard 3将继承成功的Isambard 1和2项目，提供基于日益重要的Arm架构的超级计算机服务。Isambard 3将采用NVIDIA的新型“Grace”arm处理器，该处理器将于2023年初推出，以构建快速而高效节能的服务。Isambard 3将搬进由布里斯托尔大学（University of Bristol）托管的专用设施。这个新设施位于一个新的模块化数据中心内，将首次对处理器采用直接液体冷却，减少用于冷却系统的总能量，并创造了提取和利用废热的机会。我们希望采购一个至少有6个机架、55000个核心的系统，它应该足够大，可以在2023年11月进入SC超级计算机500强名单。Isambard 3还将继续提供多架构比较系统（Multi - Architecture Comparison System，简称MACS），在Isambard 3服务的4年生命周期中，它将包含每个重要的新CPU和GPU架构的2-4个节点。这将使Arm与来自英特尔、AMD、NVIDIA和其他新兴供应商的最新cpu和gpu之间的科学严谨的架构比较成为可能。与之前的服务相比，Isambard 3服务将有一个扩展的支持团队，包括6个rse和2个技术支持方面的系统管理员，以及0.5个FTE的项目经理和一个用户社区参与和开发方面的业务开发经理。总之，Isambard基于arm的Tier-2服务的成功将扩展到支持整个UKRI更广泛的用户社区，第一个基于arm的服务器cpu专门针对高性能计算进行了优化，来自顶级芯片供应商。它将是世界上第一个这样的系统之一，并提供最节能、低碳、通用的CPU服务之一。Grace处理器应该是Isambard用户社区中最快的处理器之一，我们希望将其扩展到天气和气候应用，以及生命科学等领域。
