Development of Impact Simulation Code with GPU

我们从基于cpu的代码中开发了一个基于gpu的代码来进行冲击计算。为了快速求解方程，我们在代码中添加了一些新组件。最后，计算速度比以前基于cpu的代码快30倍。我们将代码应用于几个问题。我们对月球形成的影响进行了非常高分辨率的模拟，我们发现角动量传输的影响是很小的。我们与实验室进行了碰撞模拟的合作研究。

We developed a GPU-based code for impact calculation from CPU-based code. We added some new components to our code in order to solve the equations quickly. Finally, calculation speed becomes 30 times faster than the previous CPU-based code. We applied our code to several problems. We performed very high-resolution simulation of the moon forming impact, and we found that the effect of angular momentum transport was week. We conducted cooperative research on impact simulation with experimental lab.
