A release candidate of GMP-ECM 6.4.4 is available at
http://www.loria.fr/~kruppaal/ecm-6.4.4-rc2.tar.gz. With respect to 6.3
currently
used in Sage:
{{{
Changes between GMP-ECM 6.4.3 and GMP-ECM 6.4.4:
* Fixed PowerPC64 assembly code with --enable-shared (thanks Leif
Leonhardy)
* Fix to deal with change of semantics of internal GMP functions in GMP
5.1
Changes between GMP-ECM 6.4.2 and GMP-ECM 6.4.3:
* Fixed bug reported by user "lorgix" on mersenneforum
(http://www.mersenneforum.org/showpost.php?p=286385&postcount=280)
* Use 64-bit value for random seed under Windows
Changes between GMP-ECM 6.4.1 and GMP-ECM 6.4.2:
* Corrected the copyright headers
* Reduced memory usage in stage 1 with -batch={1,2} mode.
* Fixed bug in modular reduction (could occur only for numbers larger than
386 digits on 64-bit computers and 193 digits on 32-bit computers).
* Speedup in stage 2 with the NTT default mode
Changes between GMP-ECM 6.4 and GMP-ECM 6.4.1:
* GMP-ECM is now distributed under the GPL version 3 or later for the
binary,
and under the LGPL version 3 or later for the library
* Fixed a speed regression with respect to GMP-ECM 6.3
http://lists.gforge.inria.fr/pipermail/ecm-
discuss/2012-February/004103.html
* Fixed a bug with the -treefile option which had been present for a long
time
* Several fixes for the Visual Studio 2010 build
* New experimental option -batch=2, and speedup for -batch (i.e.,
-batch=1)
* New tuning mechanism, now --enable-asm-redc is always recommended
* New configure option --enable-mulredc-svoboda, for input numbers whose
low
limbs is congruent to -1
* New tuning parameters for Intel Core i5
* New ecmbench utility
Changes between GMP-ECM 6.3 and GMP-ECM 6.4:
* Fixed configure problem with SSE2
(http://trac.sagemath.org/sage_trac/ticket/10252)
* Fixed configure bug on 32-bit PowerPC (tried to use 64-bit assembly)
https://gforge.inria.fr/tracker/index.php?func=detail&aid=10646
* Fixed dependencies from build directory
https://gforge.inria.fr/tracker/index.php?func=detail&aid=10648
* Patch from David Cleaver to allow B1 >= 2^32 on machines where
"unsigned long" has 32 bits only
* Patch from David Cleaver to use GWNUM 26.6 on Windows x64 with
MingW64/Msys
* Improved conversion from mpz_t to residue number system in NTT code
* Better asm code for AMD cpus
* Use of GMP's mpn_mullo_n and mpn_redc_2 when available
* New option -batch with faster Stage 1 (but smaller success probability)
* Added Visual Studio 2010 build
}}}
We plan to release 6.4.4 on Friday 22 February 2013. Any feedback from the
Sage developers is welcome until then.
