Building an Application

Normally, the only change needed to build your application with MPI FFTW wrappers replacing original FFTW3 library is to add
Intel® oneAPI Math Kernel Library
 and the wrapper library at the link stage (see section "
Linking Your Application with
Intel® oneAPI
 Math Kernel Library
" in the
Intel® oneAPI Math Kernel Library
 Developer Guide
).
When you are recompiling your application, add subdirectory
include\fftw
 to the search path for header files to avoid FFTW3 version conflicts.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
