All Intel® Integrated Performance Primitives functions are thread-safe. They support multithreading in both dynamic and static libraries and can be used in multi-threaded applications. However, if an application has its own threading model or if other threaded applications are expected to run at the same time on the system, it is strongly recommended to use non-threaded/single-threaded libraries.
Multi-threaded static and dynamic libraries are available as a separate download to support legacy applications. For new development, please use the single-threaded versions with application-level threading. One way to add application-level threading is to use Intel® Threading Building Blocks (Intel® TBB).
Some Intel IPP functions contain OpenMP* code, which increases performance on multi-processor and multi-core systems. These functions include color conversion, filtering, convolution, cryptography, cross-correlation, matrix computation, square distance, and bit reduction.
To see the list of all threaded APIs, refer to the ThreadedFunctionsList.txt file located in the documentation directory of the Intel IPP installation.
Internally threaded (multi-threaded) versions of Intel® IPP libraries are deprecated but made available for legacy applications. It is strongly recommended to use single-threaded version of the library.
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.
