Introduction
benchFFT is program to benchmark FFT software, written by Matteo
Frigo and Steven
G. Johnson at MIT. The benchmark
incorporates a large number of publicly-available FFT implementations,
both in C and in Fortran, and measures their performance and accuracy
over a wide range of transform sizes. The latest version of benchFFT,
along with benchmark results on a variety of machines and compilers,
can be found at the benchFFT home page:
http://theory.lcs.mit.edu/~benchfft
This manual describes the usage and methodology of the benchmark,
and also explains the process by which new FFTs may be added. (If you
do add a new FFT, or have results on a new machine, please let us know.)
