CUDA 中的随机数生成器 [英] Random Number Generator in CUDA

问题描述

我整天都在为此苦苦挣扎，我试图在我的 CUDA 代码中为线程获取一个随机数生成器.我浏览了所有论坛，是的，这个话题出现了很多，但我花了几个小时试图解开各种代码，但无济于事.如果有人知道一个简单的方法，可能是一个 device 内核，可以调用它来返回 0 到 1 之间的随机浮点数，或者我可以转换的整数，我将不胜感激.

I've struggled with this all day, I am trying to get a random number generator for threads in my CUDA code. I have looked through all forums and yes this topic comes up a fair bit but I've spent hours trying to unravel all sorts of codes to no avail. If anyone knows of a simple method, probably a device kernel that can be called to returns a random float between 0 and 1, or an integer that I can transform I would be most grateful.

再次，我希望在内核中使用随机数，就像 rand() 一样.

Again, I hope to use the random number in the kernel, just like rand() for instance.

提前致谢

推荐答案

我不确定我理解你为什么需要一些特别的东西.任何传统的 PRNG 都应该或多或少地直接移植.线性同余 应该可以正常工作.您是否有一些正在尝试建立的特殊属性?

I'm not sure I understand why you need anything special. Any traditional PRNG should port more or less directly. A linear congruential should work fine. Do you have some special properties you're trying to establish?
