WebJun 21, 2024 · In his hands FFTW runs slightly faster than Intel MKL. In my hands MKL is ~50% faster. Maybe I didn't squeeze all the performance from FFTW.) FFTW is not the fastest one anymore, but it still has many advantages and it is the reference point for other libraries. MKL (Intel Math Kernel Library) FFT is significantly faster. It's not open-source ... WebApr 13, 2024 · We build fftw three times for different libraries in different numerical precisions: the default double precision floating point, the older 32-bit (single precision) version named float which sacrifices precision for speed, and the long double which offers increased precision at the cost of slower execution.

WebJun 19, 2024 · FFTW is a free collection of C routines for computing the discrete Fourier Transform (DFT) in one or more dimensions, and provides portability across platforms. The Intel Math Kernel Library (MKL) offers FFTW2 (for version 2. x) and FFTW3 (for version 3. WebFFTW will check if these routines can be really used on the current CPU when the FFTW library is loaded, so a FFTW build with these routines enabled can still run on a CPU without SSE2, AVX, or AVX512. These options are not compatible with --enable-long-double.
