Chris@19 57
Chris@19 58 <p>Matteo Frigo was supported in part by the Special Research Program SFB
Chris@19 59 F011 &ldquo;AURORA&rdquo; of the Austrian Science Fund FWF and by MIT Lincoln
Chris@19 60 Laboratory. For previous versions of FFTW, he was supported in part by the
Chris@19 61 Defense Advanced Research Projects Agency (DARPA), under Grants
Chris@19 62 N00014-94-1-0985 and F30602-97-1-0270, and by a Digital Equipment
Chris@19 63 Corporation Fellowship.
Chris@19 64
Chris@19 65 <p>Steven G. Johnson was supported in part by a Dept. of Defense NDSEG
Chris@19 66 Fellowship, an MIT Karl Taylor Compton Fellowship, and by the Materials
Chris@19 67 Research Science and Engineering Center program of the National Science
Chris@19 68 Foundation under award DMR-9400334.
Chris@19 69
Chris@19 70 <p>Code for the Cell Broadband Engine was graciously donated to the FFTW
Chris@19 71 project by the IBM Austin Research Lab and included in fftw-3.2. (This
Chris@19 72 code was removed in fftw-3.3.)
Chris@19 73
Chris@19 74 <p>Code for the MIPS paired-single SIMD support was graciously donated to
Chris@19 75 the FFTW project by CodeSourcery, Inc.
Chris@19 76
Chris@19 77 <p>We are grateful to Sun Microsystems Inc. for its donation of a
Chris@19 78 cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These
Chris@19 79 machines served as the primary platform for the development of early
Chris@19 80 versions of FFTW.
Chris@19 81
Chris@19 82 <p>We thank Intel Corporation for donating a four-processor Pentium Pro
Chris@19 83 machine. We thank the GNU/Linux community for giving us a decent OS to
Chris@19 84 run on that machine.
Chris@19 85
Chris@19 86 <p>We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+
Chris@19 87 computer to the FFTW project.
Chris@19 88
Chris@19 89 <p>We thank the Compaq/HP testdrive program and VA Software Corporation
Chris@19 90 (SourceForge.net) for providing remote access to machines that were used
Chris@19 91 to test FFTW.
Chris@19 92
Chris@19 93 <p>The <code>genfft</code> suite of code generators was written using Objective
Chris@19 94 Caml, a dialect of ML. Objective Caml is a small and elegant language
Chris@19 95 developed by Xavier Leroy. The implementation is available from
Chris@19 96 <a href="http://caml.inria.fr/"><code>http://caml.inria.fr/</code></a>. In previous
Chris@19 97 releases of FFTW, <code>genfft</code> was written in Caml Light, by the same
Chris@19 98 authors. An even earlier implementation of <code>genfft</code> was written in
Chris@19 99 Scheme, but Caml is definitely better for this kind of application.

Chris@19 101
Chris@19 102 <p>FFTW uses many tools from the GNU project, including <code>automake</code>,
Chris@19 103 <code>texinfo</code>, and <code>libtool</code>.
Chris@19 104
Chris@19 105 <p>Prof. Charles E. Leiserson of MIT provided continuous support and
Chris@19 106 encouragement. This program would not exist without him. Charles also
Chris@19 107 proposed the name &ldquo;codelets&rdquo; for the basic FFT blocks.
Chris@19 108 <a name="index-codelet-632"></a>
Chris@19 109
Chris@19 110 <p>Prof. John D. Joannopoulos of MIT demonstrated continuing tolerance of
Chris@19 111 Steven's &ldquo;extra-curricular&rdquo; computer-science activities, as well as
Chris@19 112 remarkable creativity in working them into his grant proposals.
Chris@19 113 Steven's physics degree would not exist without him.
Chris@19 114
Chris@19 115 <p>Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually
Chris@19 116 led to the SIMD support in FFTW 3.
Chris@19 117
Chris@19 118 <p>Stefan Kral wrote most of the K7 code generator distributed with FFTW
Chris@19 119 3.0.x and 3.1.x.
Chris@19 120
Chris@19 121 <p>Andrew Sterian contributed the Windows timing code in FFTW 2.
Chris@19 122
Chris@19 123 <p>Didier Miras reported a bug in the test procedure used in FFTW 1.2. We
Chris@19 124 now use a completely different test algorithm by Funda Ergun that does
Chris@19 125 not require a separate FFT program to compare against.
Chris@19 126
Chris@19 127 <p>Wolfgang Reimer contributed the Pentium cycle counter and a few fixes
Chris@19 128 that help portability.
Chris@19 129
Chris@19 130 <p>Ming-Chang Liu uncovered a well-hidden bug in the complex transforms of
Chris@19 131 FFTW 2.0 and supplied a patch to correct it.
Chris@19 132
Chris@19 133 <p>The FFTW FAQ was written in <code>bfnn</code> (Bizarre Format With No Name)
Chris@19 134 and formatted using the tools developed by Ian Jackson for the Linux
Chris@19 135 FAQ.
Chris@19 136
Chris@19 137 <p><em>We are especially thankful to all of our users for their
Chris@19 138 continuing support, feedback, and interest during our development of
Chris@19 139 FFTW.</em>
