Software Development for UKQCD

夸克和胶子之间的强相互作用似乎导致它们永久地被束缚在称为强子的束缚态中，就像质子和介子一样，并且可以用量子场理论QCD来描述。相反，试图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中的理论计算与它们相关联。QCD的复杂性要求使用性能最高的计算机进行仿真，这些计算机通常是专门为此开发的。这种大规模的计算工作通常是由国际合作来完成的，他们正在开发开源社区代码，这些代码在一系列计算平台上有效地运行。自1989年以来，UKQCD合作将英国在这一领域的研究联合起来，是全球领先的团体之一。除了其多样化的物理课程外，UKQCD还为世界领先的硬件，软件和数据管理工具的开发做出了贡献。该提案将增强国际社区代码库的功能和性能，使其能够在新的多核处理器上有效运行，并扩展可模拟的物理范围，包括粲夸克、非零密度系统和更基本尺度的新物理理论，这些信号可能在大型强子对撞机上发现。

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.
