如何在cuda中生成伪随机 [英] How to generate pseudo random in cuda

问题描述

我试图构建一个利用CUDA进行重型提升的粒子系统。我想随机化一些粒子的初始值，如速度和寿命。随机数不必是超随机的，因为它只是为了视觉效果。我发现这篇文章涉及相同的主题：

I am attempting to build a particle system utilizing CUDA to do the heavy lifting. I want to randomize some of the particles' initial values like velocity and life span. The random numbers don't have to be super random since it's just for visual effect. I found this post that addresses the same subject:

CUDA中的随机数生成

这表明线性同余是要走的路。它似乎应该很容易实现，但我无法获得任何有用的我的实现。

That suggests a linear congruential is the way to go. It seems like it should be simple to implement, but I am having trouble getting anything useful of my implementation. Can anyone provide some code that will run in the device?

我在Windows 7 64位上使用CUDA和VC ++。

I am using CUDA with VC++ on Windows 7 64bit.

推荐答案

包含在NVidia SDK中的CUDA伪随机数生成器是

CUDA pseudo random number generators are

< C / src / MersenneTwister / 和 C / src / quasirandomGenerator

以单独的论文和来源提供：

available as separate papers and source:

2.a Langdon的论文和 Langdon的源代码

2.b Mersenne Twister on GPU
