   Matteo Frigo was supported in part by the Defense Advanced Research
Projects Agency (DARPA) under Grants N00014-94-1-0985 and
F30602-97-1-0270, and by a Digital Equipment Corporation Fellowship.
Steven G. Johnson was supported in part by a DoD NDSEG Fellowship, an
MIT Karl Taylor Compton Fellowship, and by the Materials Research
Science and Engineering Center program of the National Science
Foundation under award DMR-9400334.

   Both authors were also supported in part by their respective
girlfriends, by the letters "Q" and "R", and by the number 12.

   We are grateful to SUN Microsystems Inc. for its donation of a
cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These
machines served as the primary platform for the development of earlier
versions of FFTW.

   We thank Intel Corporation for donating a four-processor Pentium Pro
machine.  We thank the Linux community for giving us a decent OS to run
on that machine.

   The `genfft' program was written using Objective Caml, a dialect of
ML.  Objective Caml is a small and elegant language developed by Xavier
Leroy.  The implementation is available from `ftp.inria.fr' in the
directory `lang/caml-light'.  We used versions 1.07 and 2.00 of the
software.  In previous releases of FFTW, `genfft' was written in Caml
Light, by the same authors.  An even earlier implementation of `genfft'
was written in Scheme, but Caml is definitely better for this kind of
application.

   FFTW uses many tools from the GNU project, including `automake',
`texinfo', and `libtool'.

   Prof. Charles E. Leiserson of MIT provided continuous support and
encouragement.  This program would not exist without him.  Charles also
proposed the name "codelets" for the basic FFT blocks.

   Prof. John D. Joannopoulos of MIT demonstrated continuing tolerance
of Steven's "extra-curricular" computer-science activities.  Steven's
chances at a physics degree would not exist without him.

   Andrew Sterian contributed the Windows timing code.

   Didier Miras reported a bug in the test procedure used in FFTW 1.2.
We now use a completely different test algorithm by Funda Ergun that
does not require a separate FFT program to compare against.

   Wolfgang Reimer contributed the Pentium cycle counter and a few fixes
that help portability.

   Ming-Chang Liu uncovered a well-hidden bug in the complex transforms
of FFTW 2.0 and supplied a patch to correct it.

   The FFTW FAQ was written in `bfnn' (Bizarre Format With No Name) and
formatted using the tools developed by Ian Jackson for the Linux FAQ.

   *We are especially thankful to all of our users for their continuing
support, feedback, and interest during our development of FFTW.*
