|
|
<p>Torbjörn Granlund wrote the original GMP library and is still the main
|
|
developer. Code not explicitly attributed to others, was contributed by
|
|
Torbjörn. Several other individuals and organizations have contributed
|
|
GMP. Here is a list in chronological order on first contribution:
|
|
</p>
|
|
<p>Gunnar Sjödin and Hans Riesel helped with mathematical problems in early
|
|
versions of the library.
|
|
</p>
|
|
<p>Richard Stallman helped with the interface design and revised the first
|
|
version of this manual.
|
|
</p>
|
|
<p>Brian Beuning and Doug Lea helped with testing of early versions of the
|
|
library and made creative suggestions.
|
|
</p>
|
|
<p>John Amanatides of York University in Canada contributed the function
|
|
<code>mpz_probab_prime_p</code>.
|
|
</p>
|
|
<p>Paul Zimmermann wrote the REDC-based mpz_powm code, the Schönhage-Strassen
|
|
FFT multiply code, and the Karatsuba square root code. He also improved the
|
|
Toom3 code for GMP 4.2. Paul sparked the development of GMP 2, with his
|
|
comparisons between bignum packages. The ECMNET project Paul is organizing
|
|
was a driving force behind many of the optimizations in GMP 3. Paul also
|
|
wrote the new GMP 4.3 nth root code (with Torbjörn).
|
|
</p>
|
|
<p>Ken Weber (Kent State University, Universidade Federal do Rio Grande do Sul)
|
|
contributed now defunct versions of <code>mpz_gcd</code>, <code>mpz_divexact</code>,
|
|
<code>mpn_gcd</code>, and <code>mpn_bdivmod</code>, partially supported by CNPq (Brazil)
|
|
grant 301314194-2.
|
|
</p>
|
|
<p>Per Bothner of Cygnus Support helped to set up GMP to use Cygnus’ configure.
|
|
He has also made valuable suggestions and tested numerous intermediary
|
|
releases.
|
|
</p>
|
|
<p>Joachim Hollman was involved in the design of the <code>mpf</code> interface, and in
|
|
the <code>mpz</code> design revisions for version 2.
|
|
</p>
|
|
<p>Bennet Yee contributed the initial versions of <code>mpz_jacobi</code> and
|
|
<code>mpz_legendre</code>.
|
|
</p>
|
|
<p>Andreas Schwab contributed the files <samp>mpn/m68k/lshift.S</samp> and
|
|
<samp>mpn/m68k/rshift.S</samp> (now in <samp>.asm</samp> form).
|
|
</p>
|
|
<p>Robert Harley of Inria, France and David Seal of ARM, England, suggested clever
|
|
improvements for population count. Robert also wrote highly optimized
|
|
Karatsuba and 3-way Toom multiplication functions for GMP 3, and contributed
|
|
the ARM assembly code.
|
|
</p>
|
|
<p>Torsten Ekedahl of the Mathematical department of Stockholm University provided
|
|
significant inspiration during several phases of the GMP development. His
|
|
mathematical expertise helped improve several algorithms.
|
|
</p>
|
|
<p>Linus Nordberg wrote the new configure system based on autoconf and
|
|
implemented the new random functions.
|
|
</p>
|
|
<p>Kevin Ryde worked on a large number of things: optimized x86 code, m4 asm
|
|
macros, parameter tuning, speed measuring, the configure system, function
|
|
inlining, divisibility tests, bit scanning, Jacobi symbols, Fibonacci and Lucas
|
|
number functions, printf and scanf functions, perl interface, demo expression
|
|
parser, the algorithms chapter in the manual, <samp>gmpasm-mode.el</samp>, and
|
|
various miscellaneous improvements elsewhere.
|
|
</p>
|
|
<p>Kent Boortz made the Mac OS 9 port.
|
|
</p>
|
|
<p>Steve Root helped write the optimized alpha 21264 assembly code.
|
|
</p>
|
|
<p>Gerardo Ballabio wrote the <samp>gmpxx.h</samp> C++ class interface and the C++
|
|
<code>istream</code> input routines.
|
|
</p>
|
|
<p>Jason Moxham rewrote <code>mpz_fac_ui</code>.
|
|
</p>
|
|
<p>Pedro Gimeno implemented the Mersenne Twister and made other random number
|
|
improvements.
|
|
</p>
|
|
<p>Niels Möller wrote the sub-quadratic GCD, extended GCD and jacobi code, the
|
|
quadratic Hensel division code, and (with Torbjörn) the new divide and
|
|
conquer division code for GMP 4.3. Niels also helped implement the new Toom
|
|
multiply code for GMP 4.3 and implemented helper functions to simplify Toom
|
|
evaluations for GMP 5.0. He wrote the original version of mpn_mulmod_bnm1, and
|
|
he is the main author of the mini-gmp package used for gmp bootstrapping.
|
|
</p>
|
|
<p>Alberto Zanoni and Marco Bodrato suggested the unbalanced multiply strategy,
|
|
and found the optimal strategies for evaluation and interpolation in Toom
|
|
multiplication.
|
|
</p>
|
|
<p>Marco Bodrato helped implement the new Toom multiply code for GMP 4.3 and
|
|
implemented most of the new Toom multiply and squaring code for 5.0.
|
|
He is the main author of the current mpn_mulmod_bnm1, mpn_mullo_n, and
|
|
mpn_sqrlo. Marco also wrote the functions mpn_invert and mpn_invertappr,
|
|
and improved the speed of integer root extraction. He is the author of
|
|
the current combinatorial functions: binomial, factorial, multifactorial,
|
|
primorial.
|
|
</p>
|
|
<p>David Harvey suggested the internal function <code>mpn_bdiv_dbm1</code>, implementing
|
|
division relevant to Toom multiplication. He also worked on fast assembly
|
|
sequences, in particular on a fast AMD64 <code>mpn_mul_basecase</code>. He wrote
|
|
the internal middle product functions <code>mpn_mulmid_basecase</code>,
|
|
<code>mpn_toom42_mulmid</code>, <code>mpn_mulmid_n</code> and related helper routines.
|
|
</p>
|
|
<p>Martin Boij wrote <code>mpn_perfect_power_p</code>.
|
|
</p>
|
|
<p>Marc Glisse improved <samp>gmpxx.h</samp>: use fewer temporaries (faster),
|
|
specializations of <code>numeric_limits</code> and <code>common_type</code>, C++11
|
|
features (move constructors, explicit bool conversion, UDL), make the
|
|
conversion from <code>mpq_class</code> to <code>mpz_class</code> explicit, optimize
|
|
operations where one argument is a small compile-time constant, replace
|
|
some heap allocations by stack allocations. He also fixed the eofbit
|
|
handling of C++ streams, and removed one division from <samp>mpq/aors.c</samp>.
|
|
</p>
|
|
<p>David S Miller wrote assembly code for SPARC T3 and T4.
|
|
</p>
|
|
<p>Mark Sofroniou cleaned up the types of mul_fft.c, letting it work for huge
|
|
operands.
|
|
</p>
|
|
<p>Ulrich Weigand ported GMP to the powerpc64le ABI.
|
|
</p>
