Detailed Description

template<class RealType = float>
class rocrand_cpp::uniform_real_distribution< RealType >

Produces random floating-point values uniformly distributed on the interval (0, 1].

Template Parameters
RealType- type of generated values. Only float, double and half types are supported.

Member Function Documentation

◆ operator()()

template<class RealType = float>
template<class Generator >
void rocrand_cpp::uniform_real_distribution< RealType >::operator() ( Generator &  g,
RealType *  output,
size_t  size 
)
inline

Fills output with uniformly distributed random floating-point values.

Generates size random floating-point values uniformly distributed on the interval (0, 1], and stores them into the device memory referenced by output pointer.

Parameters
g- An uniform random number generator object
output- Pointer to device memory to store results
size- Number of values to generate

Requirements:

  • The device memory pointed by output must have been previously allocated and be large enough to store at least size values of RealType type.
  • If generator g is a quasi-random number generator (rocrand_cpp::sobol32_engine), then size must be a multiple of that generator's dimension.
