Input Parameters

engine

Pointer to the engine.

distr

Pointer to the distribution.

Description

The svrng_generate[n]_[int|float|double] functions generate distributed random values based on the input engine and distribution specified. The output types that are supported—int, float, or double—depend on the distribution used. The number n if specified expresses the number of packed elements desired in the returned SIMD registers.

Status flags set

Name

Description

SVRNG_STATUS_ERROR_UNSUPPORTED

Unmatched engine and result type. See the Description section for supported combinations.

SVRNG_STATUS_ERROR_BAD_ENGINE

Bad engine (NULL pointer)

SVRNG_STATUS_ERROR_BAD_DISTR

Bad distribution (NULL pointer)

Return Values

The svrng_generate_[int|long|double] functions return a single random value of the specified type. The svrng_generate[n]_[int|long|double] functions, for n=1, 2, 4, 8, 16, or 32, return as many signed random values packed in a SIMD register.
