Describe
Dynamically load dfti functions from onemkl.
Add mkl as a fft backend when it is avaialble and requested, refer to related pr #35665
To enable mkl as an fft backend, follow the steps below.
Install oneMKL
Download onemkl from intel's website
https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/download.html
Install oneMKL
compile paddle with oneMKL support
-DWITH_ONEMKL=ONwhen generating build system for paddle.Add oneMKL's library path into $LD_LIBRARY_PATH
source setvars.shadd oneMKL's environment variables will be set up.You can add this to
.bashrc_profileor.bashrcto do this automatically.NOTE: oneMKL's library path must be included in $LD_LIBRARY_PATH to use mkl as a fft backend correctly.
