摘要：

我们研究了格点QCD模拟中奇偶Wilson费米子矩阵在A64 FX结构上的实现。有效的编码的模板操作的二维包装SIMD向量进行了研究。我们在RIKEN R-CCS的超级计算机Fugaku上测量了持续性能，并显示了我们代码的分析结果，除了代码每个部分的详细效率之外，这可能还表明了一个意想不到的慢下来的来源。

英文摘要：

We study the implementation of the even-odd Wilson fermion matrix for lattice QCD simulations on the A64FX architecture. Efficient coding of the stencil operation is investigated for two-dimensional packing to SIMD vectors. We measure the sustained performance on the supercomputer Fugaku at RIKEN R-CCS and show the profiler result of our code, which may signal an unexpected source of slow-down in addition to the detailed efficiency of each part of the code.
