cannam@127:Matteo Frigo was supported in part by the Special Research Program SFB cannam@127: F011 “AURORA” of the Austrian Science Fund FWF and by MIT Lincoln cannam@127: Laboratory. For previous versions of FFTW, he was supported in part by the cannam@127: Defense Advanced Research Projects Agency (DARPA), under Grants cannam@127: N00014-94-1-0985 and F30602-97-1-0270, and by a Digital Equipment cannam@127: Corporation Fellowship. cannam@127:
cannam@127:Steven G. Johnson was supported in part by a Dept. of Defense NDSEG cannam@127: Fellowship, an MIT Karl Taylor Compton Fellowship, and by the Materials cannam@127: Research Science and Engineering Center program of the National Science cannam@127: Foundation under award DMR-9400334. cannam@127:
cannam@127:Code for the Cell Broadband Engine was graciously donated to the FFTW cannam@127: project by the IBM Austin Research Lab and included in fftw-3.2. (This cannam@127: code was removed in fftw-3.3.) cannam@127:
cannam@127:Code for the MIPS paired-single SIMD support was graciously donated to cannam@127: the FFTW project by CodeSourcery, Inc. cannam@127:
cannam@127:We are grateful to Sun Microsystems Inc. for its donation of a cannam@127: cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These cannam@127: machines served as the primary platform for the development of early cannam@127: versions of FFTW. cannam@127:
cannam@127:We thank Intel Corporation for donating a four-processor Pentium Pro cannam@127: machine. We thank the GNU/Linux community for giving us a decent OS to cannam@127: run on that machine. cannam@127:
cannam@127:We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+ cannam@127: computer to the FFTW project. cannam@127:
cannam@127:We thank the Compaq/HP testdrive program and VA Software Corporation cannam@127: (SourceForge.net) for providing remote access to machines that were used cannam@127: to test FFTW. cannam@127:
cannam@127:The genfft
suite of code generators was written using Objective
cannam@127: Caml, a dialect of ML. Objective Caml is a small and elegant language
cannam@127: developed by Xavier Leroy. The implementation is available from
cannam@127: http://caml.inria.fr/
. In previous
cannam@127: releases of FFTW, genfft
was written in Caml Light, by the same
cannam@127: authors. An even earlier implementation of genfft
was written in
cannam@127: Scheme, but Caml is definitely better for this kind of application.

FFTW uses many tools from the GNU project, including automake
,
cannam@127: texinfo
, and libtool
.

Prof. Charles E. Leiserson of MIT provided continuous support and cannam@127: encouragement. This program would not exist without him. Charles also cannam@127: proposed the name “codelets” for the basic FFT blocks. cannam@127: cannam@127:
cannam@127: cannam@127:Prof. John D. Joannopoulos of MIT demonstrated continuing tolerance of cannam@127: Steven’s “extra-curricular” computer-science activities, as well as cannam@127: remarkable creativity in working them into his grant proposals. cannam@127: Steven’s physics degree would not exist without him. cannam@127:
cannam@127:Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually cannam@127: led to the SIMD support in FFTW 3. cannam@127:
cannam@127:Stefan Kral wrote most of the K7 code generator distributed with FFTW cannam@127: 3.0.x and 3.1.x. cannam@127:
cannam@127:Andrew Sterian contributed the Windows timing code in FFTW 2. cannam@127:
cannam@127:Didier Miras reported a bug in the test procedure used in FFTW 1.2. We cannam@127: now use a completely different test algorithm by Funda Ergun that does cannam@127: not require a separate FFT program to compare against. cannam@127:
cannam@127:Wolfgang Reimer contributed the Pentium cycle counter and a few fixes cannam@127: that help portability. cannam@127:
cannam@127:Ming-Chang Liu uncovered a well-hidden bug in the complex transforms of cannam@127: FFTW 2.0 and supplied a patch to correct it. cannam@127:
cannam@127:The FFTW FAQ was written in bfnn
(Bizarre Format With No Name)
cannam@127: and formatted using the tools developed by Ian Jackson for the Linux
cannam@127: FAQ.
cannam@127:
We are especially thankful to all of our users for their cannam@127: continuing support, feedback, and interest during our development of cannam@127: FFTW. cannam@127:
