How to draw a pseudorandom number on device?

[cgrandin]

I need to draw a pseudorandom number from a uniform distribution on the device. rand() calls the host function. Anyone know how to do this?
Thanks - sorry for cross post

There’s been some talk about generating random numbers before:

Linear congruential generators are already implemented in CUDA

See for example

Note that the generated random sequence is exactly that of the rand48 algorithm provided by the C standard library, but the implementation has been parallelized in a clever way.

I’ve modified this implementation so that random numbers can be generated, one at a time, within a CUDA device function. The code is attached.

If not, hopefully one of the other posts will help.
