Matteo Frigo was supported in part by the Special Research Program SFB
|
|
F011 ``AURORA'' of the Austrian Science Fund FWF and by MIT Lincoln
|
|
Laboratory. For previous versions of FFTW, he 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 Dept.@ of Defense 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.
|
|
|
|
Code for the Cell Broadband Engine was graciously donated to the FFTW
|
|
project by the IBM Austin Research Lab and included in fftw-3.2. (This
|
|
code was removed in fftw-3.3.)
|
|
|
|
Code for the MIPS paired-single SIMD support was graciously donated to
|
|
the FFTW project by CodeSourcery, Inc.
|
|
|
|
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 early
|
|
versions of FFTW.
|
|
|
|
We thank Intel Corporation for donating a four-processor Pentium Pro
|
|
machine. We thank the GNU/Linux community for giving us a decent OS to
|
|
run on that machine.
|
|
|
|
We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+
|
|
computer to the FFTW project.
|
|
|
|
We thank the Compaq/HP testdrive program and VA Software Corporation
|
|
(SourceForge.net) for providing remote access to machines that were used
|
|
to test FFTW.

The @code{genfft} suite of code generators 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
|
|
@uref{http://caml.inria.fr/, @code{http://caml.inria.fr/}}. In previous
|
|
releases of FFTW, @code{genfft} was written in Caml Light, by the same
|
|
authors. An even earlier implementation of @code{genfft} was written in
|
|
Scheme, but Caml is definitely better for this kind of application.

|
FFTW uses many tools from the GNU project, including @code{automake},
|
|
@code{texinfo}, and @code{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, as well as
|
|
remarkable creativity in working them into his grant proposals.
|
|
Steven's physics degree would not exist without him.

|
|
Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually
|
|
led to the SIMD support in FFTW 3.
|
|
|
|
Stefan Kral wrote most of the K7 code generator distributed with FFTW
|
|
3.0.x and 3.1.x.
|
|
|
|
Andrew Sterian contributed the Windows timing code in FFTW 2.
|
|
|
|
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 @code{bfnn} (Bizarre Format With No Name)
|
|
and formatted using the tools developed by Ian Jackson for the Linux
|
|
FAQ.
|
|
|
|
@emph{We are especially thankful to all of our users for their
|
|
continuing support, feedback, and interest during our development of
|
|
FFTW.}
