Intel IPP Threading and OpenMP* Support

All Intel IPP functions are thread-safe. They supports multithreading in both dynamic and static libraries and can be used in multithreaded applications.

Some Intel IPP functions contain OpenMP* code, which increase performance on multi-processor and multi-core systems. These functions include color conversion, filtering, convolution, cryptography, cross correlation, matrix computation, square distance, bit reduction, and so on.

Refer to the ThreadedFunctionsList.txt document to see the list of all threaded APIs in the documentation directory of the Intel IPP installation.

See also http://www.intel.com/software/products/support/ipp for more topics related to Intel IPP threading and OpenMP* support, including older Intel IPP versions of threaded API.

Optimization Notice

The Intel® Integrated Performance Primitives (Intel® IPP) library contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in the Intel® IPP library offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors.

While the paragraph above describes the basic optimization approach for the Intel® IPP library as a whole, the library may or may not be optimized to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® 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.

Intel recommends that you evaluate other library products to determine which best meets your requirements.
