My best guesses from [URL="http://ggnfs.svn.sourceforge.net/viewvc/ggnfs/trunk/src/lasieve4/gnfs-lasieve4e.c"]the source[/URL]
[code]-a or -r : sieving side -f num : first_spq -c num : sieve_count (but the .poly file values will override these, beware) -o string : out_file_name (default="spairs.out") -F : force_aFBcalc -J num : J_bits (this reduces the smaller side; the large side is compiled for efficiency and shown by the name) -L cmd : sysload_cmd (?) -M num : first_mpqs_side -P num : first_psp_side -S float : sigma -b num : base_name -i num : cmdline_first_sieve_side -k : keep_factorbase -n : catch_signals -N : process_no (?) -s : short_output -t : cmdline_first_td_side -v : verbosity level (can be used as -v -v -v) -z : zip_output (useful!) -R : resume[/code] (I tried to order, the mandatory ones first) |
does anyone know at what digit level gnfslasieve4I11e is better?

AFAIK no-one's ever actually made that one, but I'd guess 85 digits, so probably below the QS/GNFS cutoff. :yawn: again - waking up at 4 AM is taking its toll... |

:yawn: again - waking up at 4 AM is taking its toll...[/quote] i have actually i never used it but i am pretty certain that i completed a small snfs(<100digits) with gnfslasieve4I10e |
I am thinking about fiddling around with making some utilities(like for doing my own filtering and such like) for myself as a learning experience.
I understand the ggnfs format for relation files but I don't know what the formula is for working out the value of the algebraic side of a relation for a degree 5 gnfs from the a and b coordinates. This [URL="http://sourceforge.net/forum/message.php?msg_id=3718010"]link [/URL]gives an explanation for a x^6*x^3+1 snfs polynomial but i am unable to convert that to gnfs. Could someone help me out please? |
If A(x) = A5 x^5 + A4 x^4 + ... + A0 is the algebraic polynomial, then pretend x = a/b, where these are the coordinates in the relation, so that A(a,b) = b^5 *A(a/b) is the homogeneous form of the polynomial. Basically you multiply the coefficient A_i by a^i * b^(5-i).

I have now posted the ggnfs SVN360 binaries for Windows:
[url]http://gilchrist.ca/jeff/factoring/index.html[/url] Some of the changes since the last SVN340 release I published (most changes by Serge Batalov): [B]factMsieve.pl[/B] - Now reports timing for post-processing stages - Instead of extending def-par.txt for larger jobs and tiny jobs, default parameters are now calculated inside the script - Can now put minimum # of relations needed in file called MINRELS.txt instead of having to edit the script - Script can now run without "cat" utility - Some bug fixes and minor changes [B]gnfs-lasieve4e[/B] - Changes to badscheds near to schedule_primebounds - Lower memory usage with 15e and 16e sievers - Error reporting for new alloc - Optimized 64bit linux siever added to experimental/ directory |
would it be possible for the version number to be in factmsieve.pl?
currently it is near impossible to find what version you have |
Possible.

[url]http://gilchrist.ca/jeff/factoring/index.html[/url][/QUOTE] Jeff, could you also include the date* you have posted a binary in the table for that binary. Since I saw you mention that you were going to update the msieve binary with a newer gmp-ecm, there would be no way for us to know when the update happened unless we happened upon the right thread/post on the forum. Thank you for creating/hosting these binaries, I find them VERY useful. * - In your favorite format, ie: 2009/04/27 or 04/27/2009 or 27/04/2009 or 2009/27/04 or 2009-04-27 or 04-27-2009 or 27-04-2009 or 2009-27-04 [ with my personal favorite being 2009/04/27 :wink: ] |

Good idea, I'm starting to get confused now with all the updates. :smile: Dates added. You're welcome, I'm glad people find them useful. Jeff. |
