在GPU上求解具有长程相互作用的一维模型的Vlasov方程

Solving the Vlasov equation for one-dimensional models with long range interactions on a GPU

Tarcisio M. Rocha Filho

摘要:

我们提出了一个GPU并行实现的数值积分的弗拉索夫方程在一个空间维的基础上的二阶时间分裂算法与本地修改的插值样条。我们将我们的方法应用到三个不同的系统与长程相互作用:哈密顿平均场,环和自引力片模型。每个模型和不同的网格分辨率的加速比和精度。

英文摘要:

We present a GPU parallel implementation of the numeric integration of the Vlasov equation in one spatial dimension based on a second order time-split algorithm with a local modified cubic-spline interpolation. We apply our approach to three different systems with long-range interactions: the Hamiltonian Mean Field, Ring and the self-gravitating sheet models. Speedups and accuracy for each model and different grid resolutions are presented.
