项目摘要

The DiRAC High Performance Computing (HPC) facility provides cutting-edge computing services for the STFC theory communities in particle physics, astrophysics, cosmology and nuclear physics. Our complementary programmes of HPC skills training and innovation activities provide further support to the STFC theory research programme, as well as delivering significant benefits to wider society and the economy.Physicists across the astrophysics, cosmology, nuclear and particle physics communities are focussed on understanding how the Universe works at a very fundamental level. The distance scales with which they work vary by more than 40 orders of magnitude from the smallest distances probed by experiments at the Large Hadron Collider, deep within the atomic nucleus, to the largest scale galaxy clusters observed in the Universe. The science challenges, however, are linked through questions such as: How did the Universe begin and how is it evolving? and What are the fundamental constituents and fabric of the Universe and how do they interact?Progress requires a combination of new astronomical observations, new experimental data and new theoretical insights. Today, theoretical understanding comes increasingly from large-scale computations that allow us to confront, in detail, the implications of our theoretical models with data from observations or experiments, or to interrogate the data to extract information that has impact on our theories. Increasingly, theoretical calculations use artificial intelligence and machine learning algorithms to enhance their physical realism, improve their computational efficiency, or both.These computations require the performance of the fastest computers available and push the boundaries of technology in this sector. They also provide an excellent environment for training students in state-of-the-art techniques for code optimisation, data mining and visualisation; all valuable skills for their future careers.The DiRAC HPC facility has been operating since 2009, providing computing resources for theoretical researchin all areas of particle physics, astrophysics, cosmology and nuclear physics supported by STFC. It is a highly productivefacility, supporting the STFC theory community in publishing over 270 papers annually in international, peer-reviewed journals. In 2020, DiRAC received a £20m capital investment from the UKRI World Class Laboratories fund, allowing the deployment of DiRAC-3 Phase 1, the first major uplift in ourcomputational resources since DiRAC-2 in 2012 and providing a vital boost to the STFC theory programme for 2022/23.The main purpose of the funding requested in this proposal is to support the continued operation of the DiRAC HPC facility for the period 2023-2026, including staff and power costs. These resources will enable DiRAC to continue sustainably as an internationally competitive computing facility for the STFC theory community, to train the next generation of leading computational scientists and to play a lead role in the UKRI Digital Research Infrastructure over the next decade.

DiRAC高性能计算（HPC）设施为STFC理论社区提供粒子物理学，天体物理学，宇宙学和核物理学的尖端计算服务。我们的HPC技能培训和创新活动的补充计划为STFC理论研究计划提供进一步的支持，并为更广泛的社会和经济带来重大利益。天体物理学，宇宙学，核和粒子物理学社区的物理学家专注于了解宇宙如何在非常基础的水平上运作。他们工作的距离尺度变化超过40个数量级，从大型强子对撞机实验探测的最小距离，原子核深处，到宇宙中观察到的最大尺度星系团。然而，科学挑战是通过诸如宇宙是如何开始的以及它是如何演变的问题联系在一起的。宇宙的基本组成和结构是什么，它们是如何相互作用的？进步需要新的天文观测、新的实验数据和新的理论见解的结合。今天，理论理解越来越多地来自大规模计算，这使我们能够详细地面对我们的理论模型与观察或实验数据的含义，或者询问数据以提取对我们的理论有影响的信息。越来越多的理论计算使用人工智能和机器学习算法来增强物理真实性，提高计算效率，或者两者兼而有之。这些计算需要最快的计算机的性能，并推动该领域的技术边界。DiRAC HPC设施自2009年以来一直在运行，为STFC支持的粒子物理、天体物理、宇宙学和核物理等所有领域的理论研究提供计算资源。这是一个高生产力的设施，支持STFC理论界每年在国际同行评审期刊上发表270多篇论文。2020年，DiRAC从UKRI世界级实验室基金获得了2000万英镑的资本投资，允许部署DiRAC-3第1阶段，这是自2012年DiRAC-2以来我们计算资源的首次重大提升，并为2022年的STFC理论计划提供了至关重要的推动力。23.本提案中要求的资金的主要目的是支持DiRAC HPC设施在2023-2026年期间的持续运营，包括工作人员和电力费用。这些资源将使DiRAC继续可持续地作为STFC理论社区的国际竞争力计算设施，培养下一代领先的计算科学家，并在未来十年内在UKRI数字研究基础设施中发挥主导作用。
