摘要: 格子Boltzmann方法是科学与工程计算的重要模型与数值方法，该方法能够从底层描述和计算细尺度特征，同时计算量也较大。为了提高计算效率，本文主要从指令级别对格子Boltzmann数值计算进行性能优化。数值实验结果表明，优化后计算性能显著提高。
Abstract: Lattice Boltzmann method is an important model and numerical method in scientific and engi-neering calculation. It can describe and calculate the fine scale characteristics from the bottom layer, and the calculation cost is also large. In order to improve the computational efficiency, this paper mainly optimizes the performance of lattice Boltzmann numerical calculation from the in-struction level. The results of numerical experiments show that the computational performance is improved significantly after optimization.
