【摘要】：Millennium-2是目前规模最大的宇宙演化数值模拟项目。用光滑粒子动力学描述粒子对空间的影响,并用辐射传输方程构建光照模型,可绘制宇宙演化的真实感图像。由算法的能量合成保持线性形式的特点得到一种粒子并行的并行办法。将粒子足迹沿扫描线细分,可缓解程序分支扩散和粒度不均匀的问题,使该办法可以在CUDA平台上实现。测试数据证明本文的方法是有效的。
[Abstract]:Millennium-2 is the largest numerical simulation project for cosmic evolution. The smooth particle dynamics is used to describe the influence of particles on space, and the illumination model is constructed by using the radiation transfer equation. The realistic image of the evolution of the universe can be drawn. A parallel method of particle parallelism is obtained from the characteristic that the energy synthesis of the algorithm preserves the linear form. By subdividing the particle footprint along the scanning line, the problems of branch diffusion and uneven granularity can be alleviated, and the method can be implemented on the CUDA platform. The test results show that the proposed method is effective.
