This proposal, led by Bristol, is from the Consortium behind the successful Isambard Tier-2 HPC service [1]: the GW4 Alliance of Bath, Bristol, Cardiff and Exeter, in partnership with Cray and the Met Office. Isambard delivered the world's first production, Arm-based HPC service, creating significant impact for the world-wide HPC community in the process. The Isambard 2 project aims to build on this success, adding the next generation of exciting, Exascale-enabling, Arm-based technologies (Fujitsu's A64fx), while significantly expanding and upgrading the current service to meet growing demand. The A64fx CPU is generating excitement because it delivers memory bandwidth and floating point capability that is more like a GPU than a CPU (approximately 1 TeraByte/s and 3 TeraFLOP/s double precision, respectively). Providing access to these transformational technologies in parallel with an expanded Arm-based production system as a national service would be extremely advantageous to the UK's HPC community, supporting the porting and optimising of codes for future Exascale systems (the Fugaku system at RIKEN in Japan is just one example known to be based on A64fx). The Isambard 2 system will also provide one of the world's most comprehensive Multi Architecture Comparison System (MACS), significantly expanding the successful Isambard 1 MACS. The ability to compare next generation technologies with a constantly updated set of best-in-class CPUs and GPUs is a crucial part of any scientifically rigorous architectural evaluation. Being a Cray system, we will continue to uniquely offer their class-leading software toolchain to the Tier-2 community, a crucial capability to enable upward mobility from Tier-3 through Tier-2 to Tier-1.[1] https://gw4-isambard.github.io/docs/

由布里斯托尔（Bristol）领导的该提案来自成功的Isambard Tier-2 HPC服务[1]的财团：Bath，Bristol，Cardiff和Exeter的GW4联盟，与Cray和Met Office合作。 Isambard提供了世界上第一个基于ARM的HPC服务，在此过程中对全球HPC社区产生了重大影响。 Isambard 2项目旨在以这一成功为基础，并增加了下一代令人兴奋的，具有外部手臂的技术的技术（Fujitsu的A64FX），同时大大扩展并升级了当前的服务以满足不断增长的需求。 A64FX CPU引起了兴奋，因为它提供了存储器带宽和浮点功能，它比CPU更像GPU（分别为1 Terabyte/s和3 teraflop/s Double Percies）。与基于ARM的生产系统作为国民服务并行提供对这些转型技术的访问将对英国的HPC社区极为有利，支持对未来Exascale Systems的移植和优化（日本Riken的Fugaku Systems的移植和优化，这只是已知的一个基于A64FX的示例）。 Isambard 2系统还将提供世界上最全面的多体系结构比较系统（MAC）之一，从而大大扩展了成功的Isambard 1 Mac。将下一代技术与不断更新的一流CPU和GPU进行比较的能力是任何科学严格的建筑评估的关键部分。作为一个Cray系统，我们将继续向Tier-2社区提供唯一的班级领先软件工具链，这是使从TIER-3到Tier-2到Tier-1的上升移动性至关重要的关键能力。[1] https://gw4-isambard.github.io/docs/
