Detailed Description

Typedef Documentation

◆ random_device

rocrand_cpp::random_device

A non-deterministic uniform random number generator.

rocrand_cpp::random_device is non-deterministic uniform random number generator, or a pseudo-random number engine if there is no support for non-deterministic random number generation. It's implemented as a typedef of std::random_device.

For practical use rocrand_cpp::random_device is generally only used to seed a PRNG such as rocrand_cpp::mtgp32_engine.

Example:

#include <rocrand/rocrand.hpp>

int main()

{

const size_t size = 8192;

float * output;

hipMalloc(&output, size * sizeof(float));

rocrand_cpp::random_device rd;

rocrand_cpp::mtgp32 engine(rd()); // seed engine with a real random value, if available

rocrand_cpp::normal_distribution<float> dist(0.0, 1.5);

dist(engine, output, size);

}

rocrand_cpp::mtgp32_engine

Random number engine based on the Mersenne Twister for Graphic Processors algorithm.

Definition: rocrand.hpp:1675

rocrand_cpp::normal_distribution

Produces random numbers according to a normal distribution.

Definition: rocrand.hpp:351

rocrand_cpp::random_device

std::random_device random_device

A non-deterministic uniform random number generator.

Definition: rocrand.hpp:3767
