Why does MKL accelerate the matrix operation and FFT

Can anyone tell me？

Or tell me where to find the answer？

Hi Qing,

MKL is designed for providing highly optimized math function for science, engineering, data processing. Thus, it provides BLAS/LAPACK (linear Algebra) . Intel MKL includes highly vectorized and threaded Linear Algebra, Fast Fourier Transforms (FFT), Neural Network, Vector Math and Statistics functions.

You may find such information from MKL main page , MKL user guide, developer manual etc.

https://software.intel.com/en-us/intel-mkl/

and Benchmark include FFT at https://software.intel.com/en-us/intel-mkl/.

As i understand, you may start from MKLexample under MKL install folder , for example,

unzip examples_core_c package : \examples_core_c\dftc\source\basic_dp_complex_dft_1d.c

which do complex-to-complex in-place 1D FFT using Intel(R) MKL DFTI.

Best Regards,

Ying
