Automatically Getting Performance Benefits with Intel(R) IPP Threading Layer

If you already have an application that uses Intel® IPP Single-Threaded libraries, you can easily get performance benefits using the IPP Threading Layer (OpenMP* or TBB* version) without modifying your source code.
To enable IPP Threading Layer support in your application:
  1. Enable the preprocessor option
    IPP_ENABLED_THREADING_LAYER_REDEFINITIONS
    .
  2. Add Threading Layer libraries and dependencies (TBB* or OpenMP* library) into the link line. For details about Threading Layer libraries linking and location, refer to Linking Options
  3. Rebuild the application.
As a result, IPP APIs used in your application are redefined with IPP Threading Layer APIs when implemented and you receive performance benefits from external threading used in the IPP Threading Layer.

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.
