Chris@42 80
Chris@42 81 <p>Matteo Frigo was supported in part by the Special Research Program SFB
Chris@42 82 F011 &ldquo;AURORA&rdquo; of the Austrian Science Fund FWF and by MIT Lincoln
Chris@42 83 Laboratory. For previous versions of FFTW, he was supported in part by the
Chris@42 84 Defense Advanced Research Projects Agency (DARPA), under Grants
Chris@42 85 N00014-94-1-0985 and F30602-97-1-0270, and by a Digital Equipment
Chris@42 86 Corporation Fellowship.
Chris@42 87 </p>
Chris@42 88 <p>Steven G. Johnson was supported in part by a Dept.&nbsp;of Defense NDSEG
Chris@42 89 Fellowship, an MIT Karl Taylor Compton Fellowship, and by the Materials
Chris@42 90 Research Science and Engineering Center program of the National Science
Chris@42 91 Foundation under award DMR-9400334.
Chris@42 92 </p>
Chris@42 93 <p>Code for the Cell Broadband Engine was graciously donated to the FFTW
Chris@42 94 project by the IBM Austin Research Lab and included in fftw-3.2. (This
Chris@42 95 code was removed in fftw-3.3.)
Chris@42 96 </p>
Chris@42 97 <p>Code for the MIPS paired-single SIMD support was graciously donated to
Chris@42 98 the FFTW project by CodeSourcery, Inc.
Chris@42 99 </p>
Chris@42 100 <p>We are grateful to Sun Microsystems Inc.&nbsp;for its donation of a
Chris@42 101 cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These
Chris@42 102 machines served as the primary platform for the development of early
Chris@42 103 versions of FFTW.
Chris@42 104 </p>
Chris@42 105 <p>We thank Intel Corporation for donating a four-processor Pentium Pro
Chris@42 106 machine. We thank the GNU/Linux community for giving us a decent OS to
Chris@42 107 run on that machine.
Chris@42 108 </p>
Chris@42 109 <p>We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+
Chris@42 110 computer to the FFTW project.
Chris@42 111 </p>
Chris@42 112 <p>We thank the Compaq/HP testdrive program and VA Software Corporation
Chris@42 113 (SourceForge.net) for providing remote access to machines that were used
Chris@42 114 to test FFTW.
Chris@42 115 </p>
Chris@42 116 <p>The <code>genfft</code> suite of code generators was written using Objective
Chris@42 117 Caml, a dialect of ML. Objective Caml is a small and elegant language
Chris@42 118 developed by Xavier Leroy. The implementation is available from
Chris@42 119 <a href="http://caml.inria.fr/"><code>http://caml.inria.fr/</code></a>. In previous
Chris@42 120 releases of FFTW, <code>genfft</code> was written in Caml Light, by the same
Chris@42 121 authors. An even earlier implementation of <code>genfft</code> was written in
Chris@42 122 Scheme, but Caml is definitely better for this kind of application.

Chris@42 124 <a name="index-LISP"></a>
Chris@42 125 </p>
Chris@42 126
Chris@42 127 <p>FFTW uses many tools from the GNU project, including <code>automake</code>,
Chris@42 128 <code>texinfo</code>, and <code>libtool</code>.
Chris@42 129 </p>
Chris@42 130 <p>Prof.&nbsp;Charles E.&nbsp;Leiserson of MIT provided continuous support and
Chris@42 131 encouragement. This program would not exist without him. Charles also
Chris@42 132 proposed the name &ldquo;codelets&rdquo; for the basic FFT blocks.
Chris@42 133 <a name="index-codelet-3"></a>
Chris@42 134 </p>
Chris@42 135
Chris@42 136 <p>Prof.&nbsp;John D.&nbsp;Joannopoulos of MIT demonstrated continuing tolerance of
Chris@42 137 Steven&rsquo;s &ldquo;extra-curricular&rdquo; computer-science activities, as well as
Chris@42 138 remarkable creativity in working them into his grant proposals.
Chris@42 139 Steven&rsquo;s physics degree would not exist without him.
Chris@42 140 </p>
Chris@42 141 <p>Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually
Chris@42 142 led to the SIMD support in FFTW 3.
Chris@42 143 </p>
Chris@42 144 <p>Stefan Kral wrote most of the K7 code generator distributed with FFTW
Chris@42 145 3.0.x and 3.1.x.
Chris@42 146 </p>
Chris@42 147 <p>Andrew Sterian contributed the Windows timing code in FFTW 2.
Chris@42 148 </p>
Chris@42 149 <p>Didier Miras reported a bug in the test procedure used in FFTW 1.2. We
Chris@42 150 now use a completely different test algorithm by Funda Ergun that does
Chris@42 151 not require a separate FFT program to compare against.
Chris@42 152 </p>
Chris@42 153 <p>Wolfgang Reimer contributed the Pentium cycle counter and a few fixes
Chris@42 154 that help portability.
Chris@42 155 </p>
Chris@42 156 <p>Ming-Chang Liu uncovered a well-hidden bug in the complex transforms of
Chris@42 157 FFTW 2.0 and supplied a patch to correct it.
Chris@42 158 </p>
Chris@42 159 <p>The FFTW FAQ was written in <code>bfnn</code> (Bizarre Format With No Name)
Chris@42 160 and formatted using the tools developed by Ian Jackson for the Linux
Chris@42 161 FAQ.
Chris@42 162 </p>
Chris@42 163 <p><em>We are especially thankful to all of our users for their
Chris@42 164 continuing support, feedback, and interest during our development of
Chris@42 165 FFTW.</em>
