p4fftwgel2 1.2-5 (i386 binary) in ubuntu warty

Library for computing Fast Fourier Transforms on Intel P4
 This library computes Fast Fourier Transforms (FFT) in one or more
 dimensions. It is extremely fast. This package contains the shared
 version of the libraries. To get the static library and the header
 files you need to install p4fftwgel-dev.
 .
 This library uses the same interface as fftw but is not a drop-in
 replacement as it requires vectors to be 16-byte aligned. It is
 currently limited to double precision only. The code is tuned for
 Intel P4 processors and can be as much as three times as fast as
 vanilla fftw.
 .
 For documentation and test programs, install fftw-docs.
