+Cactus Code Thorn FFTW3

+1. Purpose
+
+Distribute the FFTW Library; see
+<http://www.fftw.org>
+
+
+
+From the web site: FFTW is a C subroutine library for computing the
+discrete Fourier transform (DFT) in one or more dimensions, of
+arbitrary input size, and of both real and complex data (as well as of
+even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
+We believe that FFTW, which is free software, should become the FFT
+library of choice for most applications.
+
+Our benchmarks, performed on on a variety of platforms, show that
+FFTW's performance is typically superior to that of other publicly
+available FFT software, and is even competitive with vendor-tuned
+codes. In contrast to vendor-tuned codes, however, FFTW's performance
+is portable: the same program will perform well on most architectures
+without modification. Hence the name, "FFTW," which stands for the
+somewhat whimsical title of "Fastest Fourier Transform in the West."
+
+The FFTW package was developed at MIT by Matteo Frigo and Steven G.
