Generating random numbers with uniform distribution using Thrust

Question

I need to generate a vector with random numbers between 0.0 and 1.0 using Thrust. The only documented example I could find produces ve

It might not be a direct answer to your question but, cuRand library is quite powerful in this concept. You may both generate random numbers at GPU and CPU, and it contains many distribution functions (normal distribution etc).

Search for the title: "An NVIDIA CURAND implementation" on this link: http://adnanboz.wordpress.com/tag/nvidia-curand/

//Create a new generator
curandCreateGenerator(&m_prng, CURAND_RNG_PSEUDO_DEFAULT);
//Set the generator options
curandSetPseudoRandomGeneratorSeed(m_prng, (unsigned long) mainSeed);
//Generate random numbers
curandGenerateUniform(m_prng, d_randomData, dataCount);

One note is that, do not generate the generator again and again, it makes some precalculations. Calling curandGenerateUniform is quite fast and produces values between 0.0 and 1.0.
