I use the IPP library for signal processing. Recently I needed to build my app with IPP library and run multithreaded version of FFT.
After reading the documentation library, I saw that can be run by specifying the function of a ippSetAfiinity. After starting the program creates threads, but unfortunately they are not used, use only one thread.
To build the application I use IPP library v7.1 - x64 for linux.
