rand function in CUDA

[calimirave]

Hi,

I want to generate a matrix using the function rand(or a similar function).

Is there a way to generate the matrix using the GPU or I have to generate the matrix using the CPU and copy this to the GPU?

Thanks,

There are several RNGs for CUDA:

1. Mersenne Twister in the SDK
2. rand48 (http://www.amolf.nl/~vanmeel/mdgpu/download2.html)
3. A couple more in GPU Gem3

One of the student projects I advised for last semester’s ECE498 class at UIUC implemented a few more (xorshift, and a couple others). The presentations are on the web site still, the source code may be as well, but I’m not certain:
