Intel® MKL Core Libraries Now Contain FFTW3 Interfaces

Intel® MKL 10.2 and later provides FFTW3 interfaces to enable applications using FFTW to gain performance with Intel MKL and without changing the program source code. Both FFTW2 and FFTW3 interfaces are provided as source code wrappers to Intel MKL functions.

For ease of use, the FFTW3 interface is also integrated in Intel MKL core libraries (e.g. mklcore.lib) for versions 10.2 and later. This pre-built interface is compatible with the default Intel® Fortran compiler convention for name decoration. Source code is still available to create wrappers for use with other compilers.

See Appendix F of the Reference Manual for more information about the Intel MKL FFTW wrappers.

Refer to the Intel MKL Link Line Advisor to determine which libraries to link to your application.

Optimization Notice
The Intel® Math Kernel Library (Intel® MKL) contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in Intel® MKL offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors. While the paragraph above describes the basic optimization approach for Intel® MKL as a whole, the library may or may not be optimized to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® 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. Intel recommends that you evaluate other library products to determine which best meets your requirements.
