SoftWare InFrastructure and Technology for High Energy Physics experiments (2020) at the University of Sheffield

这是PPRP最近审查的SWIFT-HEP提案的附录，该提案要求为20/21财年提供资金。HEP计划中最优先项目的计算需求构成了重大挑战，必须正面解决。四个大型强子对撞机实验（ATLAS， CMS， LHCb和ALICE）记录了近1eb的数据，从希格斯玻色子到五夸克，都有突破性的发现。大型强子对撞机实验的主要升级将在本世纪20年代进行，这将大大增加他们的数据集，同时我们将看到下一代中微子实验（DUNE和HyperK）的建立，这些实验具有大型强子对撞机规模的高粒度数据量。软件开发被国际社会认为是实现物理目标的一个重要方面。最近更新的欧洲粒子物理战略指出，该领域的未来需要专业的软件工程师，并且围绕这一研究支持领域正在形成一个国际社区。这项提议的目标是双重的。(i)所寻求的资金将对国际努力作出直接贡献，并使我们能够塑造粒子物理领域计算和软件发展的未来方向。（ii）将在英国建立一个新的跨实验协作环境，以创建一个框架来解决软件开发中的常见问题，这将在未来十年甚至更长时间内为我们服务。

This is an addendum to the SWIFT-HEP proposal recently reviewed by PPRP to request funding for FY 20/21The computing requirements of the highest priority projects within the HEP programme are posing significant challenges which must be addressed head-on. The four LHC experiments (ATLAS, CMS, LHCb and ALICE) recorded almost 1 exabyte of data to make groundbreaking discoveries, from the Higgs Boson to pentaquarks. Major upgrades of the LHC experiments are due to take place in the 2020s which will greatly augment their datasets, while in parallel we will see the build-up to operation of the next generation of neutrino experiments (DUNE and HyperK) with LHC-scale volumes of highly granular data. Software development is recognised by the international community as an essential aspect to achieve the physics goals. The recent update of the European Strategy for particle physics points out that professional software engineers are needed for the future of the field and an international community is emerging around this research support area. The goal of this proposal is two-fold. (i) The funding sought will provide a direct contribution to the international effort and allow us to shape the future direction of computing and software development in the field of particle physics. (ii) A new cross-experiment collaborative environment will be established in the UK to create a framework to address common problems in software development which will serve us for the next decade and beyond.
