格点N=4超对称Yang-Mills理论的并行软件

Parallel software for lattice N=4 supersymmetric Yang--Mills theory

David Schaich, Thomas DeGrand

摘要:

我们提出了一个新的并行软件,SUSY LATTICE,用于四维$\mathcal N = 4$规范群SU(N)的超对称杨-米尔斯理论的晶格研究。晶格作用被构造成精确地保持在非零晶格间距的单个超对称电荷,直到包括额外的势项以稳定数值模拟。该软件是从格点量子色动力学的MILC程序发展而来的,尽管目标理论不同,但仍保留了类似的大规模框架。许多例程都是从现有的串行代码改编的,而SUSY LATTICE取代了这些代码。本文提供了一个新的并行软件的概述,总结格系统,描述了目前提供的应用程序,并解释其基本工作流程的非专家格点规范理论。我们讨论了代码的并行性能,并为那些有兴趣为其未来发展做出贡献的人强调了文档中的一些值得注意的方面。

英文摘要:

We present new parallel software, SUSY LATTICE, for lattice studies of four-dimensional $\mathcal N = 4$ supersymmetric Yang--Mills theory with gauge group SU(N). The lattice action is constructed to exactly preserve a single supersymmetry charge at non-zero lattice spacing, up to additional potential terms included to stabilize numerical simulations. The software evolved from the MILC code for lattice QCD, and retains a similar large-scale framework despite the different target theory. Many routines are adapted from an existing serial code, which SUSY LATTICE supersedes. This paper provides an overview of the new parallel software, summarizing the lattice system, describing the applications that are currently provided and explaining their basic workflow for non-experts in lattice gauge theory. We discuss the parallel performance of the code, and highlight some notable aspects of the documentation for those interested in contributing to its future development.
