Vector of n 32-bit random integer numbers with uniform bit distribution. |
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.
Optimization Notice |
---|
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice revision #20110804 |
Indicates no error, execution is successful.
stream is a NULL pointer.
stream is not a valid random stream.
BRNG is not supported by the function.
Number of retries to generate a random number by using non-deterministic random number generator exceeds threshold.
ARS-5 random number generator is not supported on the CPU running the application.
