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