 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 '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
 'http://caml.inria.fr/' (http://caml.inria.fr/).  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, 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 '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._
