Some Intel® IPP functions contain OpenMP* code, which give significant performance gain on multi-processor and multi-core systems. With each version of Intel IPP a list of threaded functions is updated. These functions include color conversion, filtering, convolution, cryptography, cross correlation, matrix computation, square distance, and bit reduction, etc.
Since version 5.3 and later, you can find the list of threaded functions in "ThreadedFunctionsList.txt" under [IPP InstallDir]\doc directory of the standalone IPP product. With the Intel® Composer packages this list of threaded functions can be found in the [ComposerInstallDir]\Documentation\en_US\ipp directory. Please note, that the Composer installation directory might be a sub-dirctory of an Intel® Parallel Studio package.
The list of threaded APIs prior to v5.3 can be downloaded:

In the IPP version included with Compiler >=11.0 this file doesn't seem to exist.
Ok, I found it: It's under %ICPP_COMPILER11%\Documentation\ipp\ThreadedFunctionsList.txt
