• Threading Notes:
  • Intel® IPP provides Threading Layer APIs on top of sequential Intel® IPP libraries. The APIs include two variants 1) functions with _T suffix in the names, providing threading implementation based on classic IPP APIs; 2) functions with _LT suffix, providing threading implementation based on Intel IPP Platform-Aware functions. The Threading Layer APIs support both OpenMP* and Intel® Threading Building Blocks threading technology. Source code of Intel® IPP Threading Layer is also available in IPP package as example and basis to organize threading for pipeline inside a customer application.
  • The legacy Intel IPP threaded libraries are still available by custom installation, and the code written with these libraries will work as before. However, the threaded library will not expand its threading functions, and the new threading will be developed only in the new Intel® IPP threading layer APIs.
  • User applications are recommended to use the new Intel® IPP Threading Layer APIs or implement the threading based on IPP Threading Layer source code examples in their applications. Check the “Threading Layer Functions” section in the Intel® IPP Developer Reference, to get more information on these APIs.
