We propose to establish a new national Tier-2 HPC service ("NICE19") by purchasing and operating a novel architecture supercomputer, based upon IBM Power9 CPU and Nvidia Volta GPUs. This architecture is used in both #1 and #2 of the most recent list of the Top500 supercomputers in the world, within the USA government lab-based SUMMIT and SIERRA supercomputers. Currently this architecture is not widely available in the UK, so by establishing a national Tier-2 facility we will add significant diversity and capability to the UK e-infrastructure. This architecture supports memory coherence between the GPU and CPU and a hierarchy of interconnects to allow effective distributed GPU use, extending problem sizes that can tackled beyond that of other GPU-accelerated architectures, increasing data sizes for accelerated simulation and analysis codes, and reducing the 'time to science' for a range of 'hard' problems.The purpose of this facility is to enable new science across many different disciplines. Our primary focus will be on experimental users who generate large data sets that need analysis (e.g. cyro-EM facilities) and for modellers who use machine learning. By supporting and bringing together these two communities, there will be many opportunities for new and exciting science. This will bring HPC to many communities who have not engage with HPC before now, with many benefits in getting better value out of experiments and existing datasets. In addition, existing investments in network infrastructure for the DiRAC consortium of STFC users will be leveraged to connect the facility to experimental facilities and other Tier-2 centres for optimal data flows between sites.This proposal is led by the N8 Centre of Excellence in Computationally Intensive Research (N8-CIR) and supported by the N8 partnership. This will provide 8 FTE of Research Software Engineers (RSEs) to support these communities, port and optimize their software for this new platform and train users, which will be essential to maximize the benefit of this novel facility. These codes will then be able to run efficiently on the facility, supported by trained users. The architectural similarity with SUMMIT and SIERRA will also provide a route to exascale computing. This proposal will therefore have a long-lasting impact, beyond the lifetime fo this facility.

我们建议通过购买和操作新型建筑超级计算机，建立新的国家2 HPC服务（“ NICE19”），该服务器基于IBM Power9 CPU和Nvidia Volta GPU。该体系结构在世界政府实验室的首脑会议和塞拉超级计算机中，在世界上前500名超级计算机的最新列表中使用。目前，这种体系结构在英国尚未广泛使用，因此，通过建立国家2层设施，我们将为英国的E-Infrasture增加重要的多样性和能力。该体系结构支持GPU和CPU之间的内存连贯性以及互连的层次结构，以允许有效的分布式GPU使用，扩展了可以解决其他GPU加速架构的问题大小，从而增加了数据尺寸，以增加加速模拟和分析代码的数据尺寸，并减少该型号。对于一系列“硬”问题的“科学时间”。该设施的目的是使许多不同学科的新科学能够实现新科学。我们的主要重点是实验用户，这些用户生成需要分析的大型数据集（例如CYRO-EM设施）以及使用机器学习的建模者。通过支持和汇集这两个社区，将有很多新的和令人兴奋的科学机会。这将把HPC带到以前与HPC互动的许多社区，从实验和现有数据集中获得更高价值的许多好处。此外，将利用STFC用户的DIRAC联盟网络基础设施的现有投资将设施连接到实验设施和其他层2中心，以在网站之间进行最佳数据流。该提案是由N8 Compuctation in Compuctation in Computation in强化研究（N8-CIR），并得到N8合作伙伴关系的支持。这将提供8英尺的研究软件工程师（RSE），以支持这些社区，端口并优化其针对这个新平台和培训用户的软件，这对于最大程度地利用了这一新型设施的好处。然后，这些代码将能够在受过训练的用户的支持下在设施上有效运行。与Summit和Sierra的建筑相似性还将为Exascale计算提供一条途径。因此，该提案将产生持久的影响，超出该设施的终生。
