Distribution Initialization and Finalization

The Short Vector Random Number Generator (SVRNG) library supports the following distributions:
  • uniform
    (
    single and double floating point and 32-bit integer
    )
  • normal
    (
    single and double floating point
    )
SVRNG distributions must be initialized before random numbers can be generated. The initialization and finalization routines in this section allocate memory, pre-compute loop-invariant values and broadcast scalar constants for fast vector generation. Update functions are also provided to re-compute these numbers without memory re-allocation. More detail on the "figures of merit" for these distributions can be found in the "Figures of Merit for Random Number Generators" and "Testing of Distribution Random Number Generators" sections of the

Product and Performance Information

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.
