[I] Fastest Fourier Transform in The West
|
|
|
|
|
|
|
|
|
|
[T] FFTW is a C subroutine library for computing the
|
|
|
|
|
[T] Discrete Fourier Transform (DFT) in one or more
|
|
|
|
|
[T] dimensions, of both real and complex data, and of
|
|
|
|
|
[T] arbitrary input size. We believe that FFTW, which is
|
|
|
|
|
[T] free software, should become the FFT library of c
|
|
|
|
|
[T] choice for most applications. Our benchmarks, performed
|
|
|
|
|
[T] on on a variety of platforms, show that FFTW's
|
|
|
|
|
[T] performance is typically superior to that of other publicly
|
|
|
|
|
[T] available FFT software. Moreover, FFTW's performance
|
|
|
|
|
[T] is portable: the program will perform well on
|
|
|
|
|
[T] most architectures without modification.
|
|
|
|
|
[T]
|
|
|
|
|
[T] It is difficult to summarize in a few words all the
|
|
|
|
|
[T] complexities that arise when testing many programs, and
|
|
|
|
|
[T] there is no "best" or "fastest" program. However,
|
|
|
|
|
[T] FFTW appears to be the fastest program most of the
|
|
|
|
|
[T] time for in-order transforms, especially in the
|
|
|
|
|
[T] multi-dimensional and real-complex cases (Kasparov is
|
|
|
|
|
[T] the best chess player in the world even though he
|
|
|
|
|
[T] loses some games). Hence the name, "FFTW," which
|
|
|
|
|
[T] stands for the somewhat whimsical title of "Fastest
|
|
|
|
|
[T] Fourier Transform in the West." Please visit the
|
|
|
|
|
[T] benchFFT home page for a more extensive survey of
|
|
|
|
|
[T] the results. It comes with a MPI version and Matlab
|
|
|
|
|
[T] wrappers.
