Peter A Boyle, Dennis Bollweg, Christopher Kelly, Azusa Yamaguchi

摘要:

我们讨论的算法畴壁费米子集中在加速混合蒙特卡罗抽样规范配置。首先,一个新的多重网格算法域壁求解器,其次是域分解的混合蒙特卡洛方法适用于大型子体积和GPU加速节点优化。我们提出了一个配方的DD-RHMC是适合于奇数费米子的模拟。

英文摘要:

We discuss algorithms for domain wall fermions focussing on accelerating Hybrid Monte Carlo sampling of gauge configurations. Firstly a new multigrid algorithm for domain wall solvers and secondly a domain decomposed hybrid monte carlo approach applied to large subvolumes and optimised for GPU accelerated nodes. We propose a formulation of DD-RHMC that is suitable for the simulation of odd numbers of fermions.
