The strong interactions of quarks and gluons appear to result in their permanent confinement into bound states called hadrons, such as the proton and pion, and to be described by a quantum field theory called QCD. Experimental measurements seeking to determine the properties of quarks and gluons must, instead, be carried out on hadrons and related to them by theoretical calculations in QCD. The complexity of QCD demands its simulation using the highest performance computers, often developed specially for the purpose. This large-scale computational effort is typically carried out by international collaborations who are developing open-source community codes that run efficiently on a range of computing platforms for this work. The UKQCD Collaboration has united UK research in this field since 1989 and is one of the leading groups world-wide. In addition to its diverse physics programme, UKQCD has contributed to the development of world-leading hardware, software and data management tools. This proposal will enhance the functionality and performance of an international community code base to enable it to run efficiently on new multi-core processors, and to extend the range of physics that can be simulated to include the charm quark, systems at non-zero density and new theories of physics at a more fundamental scale, signals of which might be discovered at the Large Hadron Collider.

夸克和胶子的强相互作用似乎导致它们被永久限制在被称为强子的束束态，如质子和介子，并被称为QCD的量子场论所描述。相反，寻求确定夸克和胶子性质的实验测量必须在强子上进行，并通过QCD中的理论计算与之相关。QCD的复杂性要求它使用最高性能的计算机进行模拟，这些计算机通常是专门为此目的而开发的。这种大规模的计算工作通常是由国际合作进行的，他们正在开发在一系列计算平台上高效运行的开源社区代码来进行这项工作。UKQCD合作自1989年以来一直联合英国在这一领域的研究，是世界范围内领先的组织之一。除了其多样化的物理方案外，英国昆士兰大学还为开发世界领先的硬件、软件和数据管理工具做出了贡献。这一提议将增强国际社会代码库的功能和性能，使其能够在新的多核处理器上高效运行，并扩大可模拟的物理范围，以包括魅力夸克、非零密度系统和更基本规模的新物理理论，其信号可能会在大型强子对撞机上发现。
