Precompiled MacOS X libraries via Fink Instead of the above, the Fink project has put together precompiled/prepackaged versions of FFTW 2.x and FFTW 3.x for MacOS X. Fink provides a collection of free-software Unix tools packaged for MacOS X, based on the excellent package and system-maintainance tools developed for Debian GNU/Linux. Special Forums UNIX and Linux Applications High Performance Computing FFTW. No configure: error: could not find mpi library for -enable-mpi. The command i used was. But I can't succeed in installing them on my Mac OSX. I tried with './configure make make install' procedure, fink and macports but my programs always ask me 'fftw.h' files. Jun 27, 2018 'configure: error: could not find mpi library for -enable-mpi'. This is because FFTW configuration (using sources in the AMBERHOME tree) could not find the mpi libraries. Maybe someone on the list knows the trick to get fftw's configure script to look in /usr/local, but one of the two solutions listed above is what we recommend.

Install notes for Mac OS X. The Open MPI library and Python wrappers can be installed using Homebrew and pip. Dedalus uses the FFTW library for transforms. QUANTUM ESPRESSO has an internal copy of an old FFTW library. It also supports the newer FFTW3 library and some vendor-specific FFT libraries. Configure will first search for vendor-specific FFT libraries; if none is found, it will search for an external FFTW v.3 library; if none is found, it will fall back to the internal copy of FFTW.

The Fastest Fourier Transform in the West (FFTW) is a software library for computing discrete Fourier transforms (DFTs) developed by Matteo Frigo and Steven G. Johnson at the Massachusetts Institute of Technology.^[1][2][3]

FFTW is known as the fastest free software implementation of the fast Fourier transform (FFT) (upheld by regular benchmarks^[4]). Like many other implementations, it can compute transforms of real and complex-valued arrays of arbitrary size and dimension in O(n log n) time.

Library[edit]

It does this by supporting a variety of algorithms and choosing the one (a particular decomposition of the transform into smaller transforms) it estimates or measures to be preferable in the particular circumstances. It works best on arrays of sizes with small prime factors, with powers of two being optimal and large primes being worst case (but still O(n log n)). To decompose transforms of composite sizes into smaller transforms, it chooses among several variants of the Cooley–Tukey FFT algorithm (corresponding to different factorizations and/or different memory-access patterns), while for prime sizes it uses either Rader's or Bluestein's FFT algorithm.^[1] Once the transform has been broken up into subtransforms of sufficiently small sizes, FFTW uses hard-codedunrolled FFTs for these small sizes that were produced (at compile time, not at run time) by code generation; these routines use a variety of algorithms including Cooley–Tukey variants, Rader's algorithm, and prime-factor FFT algorithms.^[1]

For a sufficiently large number of repeated transforms it is advantageous to measure the performance of some or all of the supported algorithms on the given array size and platform. These measurements, which the authors refer to as 'wisdom', can be stored in a file or string for later use.

FFTW has a 'guru interface' that intends 'to expose as much as possible of the flexibility in the underlying FFTW architecture'. This allows, among other things, multi-dimensional transforms and multiple transforms in a single call (e.g., where the data is interleaved in memory).

FFTW has limited support for out-of-order transforms (using the Message Passing Interface (MPI) version). The data reordering incurs an overhead, which for in-place transforms of arbitrary size and dimension is non-trivial to avoid. It is undocumented for which transforms this overhead is significant.

FFTW is licensed under the GNU General Public License. It is also licensed commercially (for a cost of up to $12,500) by MIT^[5] and is used in the commercial MATLAB^[6] matrix package for calculating FFTs. FFTW is written in the C language, but Fortran and Ada interfaces exist, as well as interfaces for a few other languages. While the library itself is C, the code is actually generated from a program called 'genfft', which is written in OCaml.^[7]

In 1999, FFTW won the J. H. Wilkinson Prize for Numerical Software.
