Random Number Generator in CUDA

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.

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

Thanks in advance

Solution

  • 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?
