多GPU上强子与费米子重叠的极化率
Electric polarizability of hadrons with overlap fermions on multi-GPUs
摘要：
极化率是强子内部结构的一个重要参数。以前的极化率研究都是在相对较重的π介子质量下进行的，手征区域基本上没有被探索。在这份报告中，我们使用重叠费米子，这是已知的计算要求，以正确地捕捉手性动力学。提出了一种在多GPU上构造重叠的实现策略。我们发现我们的GPU代码相当于\sim 30个CPU核心对应1个GPU。我们还提出了中性π介子的极化率的初步结果。
英文摘要：
Electric polarizability is an important parameter for the internal structure of hadrons. Previous studies of polarizabilities have been done at relatively heavy pion masses, leaving the chiral region largely unexplored. In this report, we use overlap fermions which are known to be computationally demanding to properly capture the chiral dynamics. We present an implementation strategy to construct overlap on multi-GPUs. We find that our GPU code has an equivalent of \sim30 CPU cores to 1 GPU. We also present preliminary results for the polarizability of the neutral pion.
