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.
