Research on GPU-accelerated algorithm in 3D finite difference neutron diffusion calculation method

Research on GPU-accelerated algorithm in 3D finite difference neutron diffusion calculation method

中文摘要英文摘要

In this paper, the adaptability of the neutron diffusion numerical algorithm on GPUs was studied, and a GPU-accelerated multi-group 3D neutron diffusion code based on finite difference method was developed. The IAEA 3D PWR benchmark problem was calculated in the numerical test. The results demonstrate both high efficiency and adequate accuracy of the GPU implementation for neutron diffusion equation.
