Detailed Description

template<class IntType = unsigned int>
class rocrand_cpp::uniform_int_distribution< IntType >

Produces random integer values uniformly distributed on the interval [0, 2^(sizeof(IntType)*8) - 1].

Template Parameters

IntType

- type of generated values. Only unsigned char, unsigned short and unsigned int and unsigned long long int type is supported.

Member Function Documentation

◆ operator()()

template<class IntType = unsigned int>

template<class Generator >

void rocrand_cpp::uniform_int_distribution< IntType >::operator() ( Generator &  g, IntType *  output, size_t  size  )

inline

Fills output with uniformly distributed random integer values.

Generates size random integer values uniformly distributed on the interval [0, 2^(sizeof(IntType)*8) - 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 IntType 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.
