cannam@167 79
cannam@167 80 <p>Matteo Frigo was supported in part by the Special Research Program SFB
cannam@167 81 F011 &ldquo;AURORA&rdquo; of the Austrian Science Fund FWF and by MIT Lincoln
cannam@167 82 Laboratory. For previous versions of FFTW, he was supported in part by the
cannam@167 83 Defense Advanced Research Projects Agency (DARPA), under Grants
cannam@167 84 N00014-94-1-0985 and F30602-97-1-0270, and by a Digital Equipment
cannam@167 85 Corporation Fellowship.
cannam@167 86 </p>
cannam@167 87 <p>Steven G. Johnson was supported in part by a Dept.&nbsp;of Defense NDSEG
cannam@167 88 Fellowship, an MIT Karl Taylor Compton Fellowship, and by the Materials
cannam@167 89 Research Science and Engineering Center program of the National Science
cannam@167 90 Foundation under award DMR-9400334.
cannam@167 91 </p>
cannam@167 92 <p>Code for the Cell Broadband Engine was graciously donated to the FFTW
cannam@167 93 project by the IBM Austin Research Lab and included in fftw-3.2. (This
cannam@167 94 code was removed in fftw-3.3.)
cannam@167 95 </p>
cannam@167 96 <p>Code for the MIPS paired-single SIMD support was graciously donated to
cannam@167 97 the FFTW project by CodeSourcery, Inc.
cannam@167 98 </p>
cannam@167 99 <p>We are grateful to Sun Microsystems Inc.&nbsp;for its donation of a
cannam@167 100 cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These
cannam@167 101 machines served as the primary platform for the development of early
cannam@167 102 versions of FFTW.
cannam@167 103 </p>
cannam@167 104 <p>We thank Intel Corporation for donating a four-processor Pentium Pro
cannam@167 105 machine. We thank the GNU/Linux community for giving us a decent OS to
cannam@167 106 run on that machine.
cannam@167 107 </p>
cannam@167 108 <p>We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+
cannam@167 109 computer to the FFTW project.
cannam@167 110 </p>
cannam@167 111 <p>We thank the Compaq/HP testdrive program and VA Software Corporation
cannam@167 112 (SourceForge.net) for providing remote access to machines that were used
cannam@167 113 to test FFTW.
cannam@167 114 </p>
cannam@167 115 <p>The <code>genfft</code> suite of code generators was written using Objective
cannam@167 116 Caml, a dialect of ML. Objective Caml is a small and elegant language
cannam@167 117 developed by Xavier Leroy. The implementation is available from
cannam@167 118 <a href="http://caml.inria.fr/"><code>http://caml.inria.fr/</code></a>. In previous
cannam@167 119 releases of FFTW, <code>genfft</code> was written in Caml Light, by the same
cannam@167 120 authors. An even earlier implementation of <code>genfft</code> was written in
cannam@167 121 Scheme, but Caml is definitely better for this kind of application.

cannam@167 124 </p>
cannam@167 125
cannam@167 126 <p>FFTW uses many tools from the GNU project, including <code>automake</code>,
cannam@167 127 <code>texinfo</code>, and <code>libtool</code>.
cannam@167 128 </p>
cannam@167 129 <p>Prof.&nbsp;Charles E.&nbsp;Leiserson of MIT provided continuous support and
cannam@167 130 encouragement. This program would not exist without him. Charles also
cannam@167 131 proposed the name &ldquo;codelets&rdquo; for the basic FFT blocks.
cannam@167 132 <a name="index-codelet-3"></a>
cannam@167 133 </p>
cannam@167 134
cannam@167 135 <p>Prof.&nbsp;John D.&nbsp;Joannopoulos of MIT demonstrated continuing tolerance of
cannam@167 136 Steven&rsquo;s &ldquo;extra-curricular&rdquo; computer-science activities, as well as
cannam@167 137 remarkable creativity in working them into his grant proposals.
cannam@167 138 Steven&rsquo;s physics degree would not exist without him.
cannam@167 139 </p>
cannam@167 140 <p>Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually
cannam@167 141 led to the SIMD support in FFTW 3.
cannam@167 142 </p>
cannam@167 143 <p>Stefan Kral wrote most of the K7 code generator distributed with FFTW
cannam@167 144 3.0.x and 3.1.x.
cannam@167 145 </p>
cannam@167 146 <p>Andrew Sterian contributed the Windows timing code in FFTW 2.
cannam@167 147 </p>
cannam@167 148 <p>Didier Miras reported a bug in the test procedure used in FFTW 1.2. We
cannam@167 149 now use a completely different test algorithm by Funda Ergun that does
cannam@167 150 not require a separate FFT program to compare against.
cannam@167 151 </p>
cannam@167 152 <p>Wolfgang Reimer contributed the Pentium cycle counter and a few fixes
cannam@167 153 that help portability.
cannam@167 154 </p>
cannam@167 155 <p>Ming-Chang Liu uncovered a well-hidden bug in the complex transforms of
cannam@167 156 FFTW 2.0 and supplied a patch to correct it.
cannam@167 157 </p>
cannam@167 158 <p>The FFTW FAQ was written in <code>bfnn</code> (Bizarre Format With No Name)
cannam@167 159 and formatted using the tools developed by Ian Jackson for the Linux
cannam@167 160 FAQ.
cannam@167 161 </p>
cannam@167 162 <p><em>We are especially thankful to all of our users for their
cannam@167 163 continuing support, feedback, and interest during our development of
cannam@167 164 FFTW.</em>
