58 <p>Matteo Frigo was supported in part by the Special Research Program SFB
59 F011 &ldquo;AURORA&rdquo; of the Austrian Science Fund FWF and by MIT Lincoln
60 Laboratory. For previous versions of FFTW, he was supported in part by the
61 Defense Advanced Research Projects Agency (DARPA), under Grants
62 N00014-94-1-0985 and F30602-97-1-0270, and by a Digital Equipment
63 Corporation Fellowship.
64
65 <p>Steven G. Johnson was supported in part by a Dept. of Defense NDSEG
66 Fellowship, an MIT Karl Taylor Compton Fellowship, and by the Materials
67 Research Science and Engineering Center program of the National Science
68 Foundation under award DMR-9400334.
69
70 <p>Code for the Cell Broadband Engine was graciously donated to the FFTW
71 project by the IBM Austin Research Lab.
72
73 <p>Code for the MIPS paired-single SIMD support was graciously donated to
74 the FFTW project by CodeSourcery, Inc.
75
76 <p>We are grateful to Sun Microsystems Inc. for its donation of a
77 cluster of 9 8-processor Ultra HPC 5000 SMPs (24 Gflops peak). These
78 machines served as the primary platform for the development of early
79 versions of FFTW.
80
81 <p>We thank Intel Corporation for donating a four-processor Pentium Pro
82 machine. We thank the GNU/Linux community for giving us a decent OS to
83 run on that machine.
84
85 <p>We are thankful to the AMD corporation for donating an AMD Athlon XP 1700+
86 computer to the FFTW project.
87
88 <p>We thank the Compaq/HP testdrive program and VA Software Corporation
89 (SourceForge.net) for providing remote access to machines that were used
90 to test FFTW.
91
92 <p>The <code>genfft</code> suite of code generators was written using Objective
93 Caml, a dialect of ML. Objective Caml is a small and elegant language
94 developed by Xavier Leroy. The implementation is available from
95 <a href="http://caml.inria.fr/"><code>http://caml.inria.fr/</code></a>. In previous
96 releases of FFTW, <code>genfft</code> was written in Caml Light, by the same
97 authors. An even earlier implementation of <code>genfft</code> was written in
98 Scheme, but Caml is definitely better for this kind of application.
99 <a name="index-Caml-381"></a><a name="index-LISP-382"></a>
100 FFTW uses many tools from the GNU project, including <code>automake</code>,
101 <code>texinfo</code>, and <code>libtool</code>.
102
103 <p>Prof. Charles E. Leiserson of MIT provided continuous support and
104 encouragement. This program would not exist without him. Charles also
105 proposed the name &ldquo;codelets&rdquo; for the basic FFT blocks.
106 <a name="index-codelet-383"></a>
107 Prof. John D. Joannopoulos of MIT demonstrated continuing tolerance of
108 Steven's &ldquo;extra-curricular&rdquo; computer-science activities, as well as
109 remarkable creativity in working them into his grant proposals.
110 Steven's physics degree would not exist without him.
111
112 <p>Franz Franchetti wrote SIMD extensions to FFTW 2, which eventually
113 led to the SIMD support in FFTW 3.
114
115 <p>Stefan Kral wrote most of the K7 code generator distributed with FFTW
116 3.0.x and 3.1.x.
117
118 <p>Andrew Sterian contributed the Windows timing code in FFTW 2.
119
120 <p>Didier Miras reported a bug in the test procedure used in FFTW 1.2. We
121 now use a completely different test algorithm by Funda Ergun that does
122 not require a separate FFT program to compare against.
123
124 <p>Wolfgang Reimer contributed the Pentium cycle counter and a few fixes
125 that help portability.
126
127 <p>Ming-Chang Liu uncovered a well-hidden bug in the complex transforms of
128 FFTW 2.0 and supplied a patch to correct it.
129
130 <p>The FFTW FAQ was written in <code>bfnn</code> (Bizarre Format With No Name)
131 and formatted using the tools developed by Ian Jackson for the Linux
132 FAQ.
133
134 <p><em>We are especially thankful to all of our users for their
135 continuing support, feedback, and interest during our development of
136 FFTW.</em>
