Software Development for UKQCD

夸克和胶子的强相互作用似乎导致它们被永久限制在称为强子的束缚态中，如质子和π介子，并由称为QCD的量子场论描述。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联系起来。量子色动力学的复杂性要求它的模拟使用最高性能的计算机，往往是专门开发的目的。这种大规模的计算工作通常是由国际合作进行的，他们正在开发开源社区代码，这些代码可以在一系列计算平台上有效运行。UKQCD协作组织自1989年以来一直联合英国在该领域的研究，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。这一提议将增强国际社区代码库的功能和性能，使其能够在多核处理器上高效运行，并扩大可模拟的物理范围，以包括魅夸克、非零密度系统和更基本尺度的新物理理论，其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 theorectical 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 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.
