Input Parameters

Name	Type	Description
method	const MKL_INT	Generation method; the specific value is VSL_RNG_METHOD_UNIFORMBITS32_STD
stream	VSLStreamStatePtr	Pointer to the stream state structure
n	const MKL_INT	Number of random values to be generated

Name

Type

Description

method

const MKL_INT

Generation method; the specific value is

VSL_RNG_METHOD_UNIFORMBITS32_STD

stream

VSLStreamStatePtr

Pointer to the stream state structure

const MKL_INT

Number of random values to be generated

Output Parameters

Name	Type	Description
r	unsigned int*	Vector of `n` 32-bit random integer numbers with uniform bit distribution.

Description

The vRngUniformBits32 function generates uniformly distributed bits in 32-bit chunks. Unlike vRngUniformBits, which provides the output of underlying integer recurrence and does not guarantee uniform distribution across bits, vRngUniformBits32 is designed to ensure each bit in the 32-bit chunk is uniformly distributed. See VS Notes for details.

Return Values

VSL_ERROR_OK, VSL_STATUS_OK: Indicates no error, execution is successful.
VSL_ERROR_NULL_PTR: stream is a NULL pointer.
VSL_RNG_ERROR_BAD_STREAM: stream is not a valid random stream.
VSL_RNG_ERROR_BRNG_NOT_SUPPORTED: BRNG is not supported by the function.
VSL_RNG_ERROR_NONDETERM_NRETRIES_EXCEEDED: Number of retries to generate a random number by using non-deterministic random number generator exceeds threshold.
VSL_RNG_ERROR_ARS5_NOT_SUPPORTED: ARS-5 random number generator is not supported on the CPU running the application.
