Hi, Everytime i try a general number, getdepts is doing some ecm the first time it runs. - On what number is it doing the ecm? - 50* B1= 2000 and 150* B1= 5000...
I am intressted in the GGNFS program, and also SNFS and GNFS factorisations but till this time have not had the time to devote myself to read and learn big...
Hiya! ... From ggnfs/doc/ggnfs-doc/ggnfs-doc.tex number of digits of N, degree <75, 3 75-120, 4 120-170, 5 And there are other tables in that document you can...
... first time ... It appears to be the discriminant of the polynomial c_d^(d-1)*f(x/c_d). ... Why so ... I'm not familiar with the theory, so this is a wild...
i believe once you have created a poly definition, you can use the script, factlat.sh, to start the factorization. ... than ... degrees ... that ... GGNFS. ......
Is there any chance that the .pdf mentioned could be uploaded into the files folder? I ask because I am running off of the win exe's, which don't have it! ...
... able ... At the moment i am getting the following statement using the FactLat.pl script. At the end of getting the dependencies with getdeps it stops with...
Hello ! I have a BIG problem with a c100 that I try to factorize to familiarize myself with the use of ggnfs : The square root phase don't find the factors !!!...
ps : I forgot to tell that the version I use runs under cygwin on windows xp pro, with a duron (64+64kb cache), and *only* 256 megs of ram.... I'll try to...
... OK i read the uploaded pdf (many thnx for uploading, the tex file reading it self was a bit different) and i got it to work. Altho i have to see at the end...
Greetings, I am big fan of this algorithm. I noticed that the sieve takes an avg of 80% of the total fac time, thus I wrote a parallel sieve implementation...
Hi, Franke's lattice sieve, located in the lasieve4 directory, is significantly faster than the classical sieve. Would you be able to make a parallel version...
Hi! I tried a lattice Sieve run with the same parafile. getdeps ended the same way. It was done on my other computer. total yield: 169565, q=523793 (0.01385...
... first time ... Why so ... performance . ... It would be easy to externalize GMP-ECM as is done with the ECMNet Client. Granted, this adds a little...
I am having difficulty with the PDF in the Files section. It completely hangs Netscape 7.2. When I down to save it to a file, it tells me that it cannot be...
I know that the sieving code is tuned for x86 hardware. I haven't tried to compile it on PPC yet (but will soon). Has anyone tried compiling it on anything...
Yes, unsuccessfully. I tried to compile native Linux-AMD64 binaries. There is some inline x86 assembly in the source. Probably wouldn't be too hard to create...
Hi Mark, On the first run, it is using ECM to try to factor the discriminant of the polynomial. This is needed to compute an integral basis for the number...
Hi Philippe, Yes - this is an annoying little problem that has persisted through several versions of GGNFS. I think, though, that the problem was not actually...
... Ehhh, it did this again for _every_ dependency during the square root fase. What i did, is let getdepts run a few curves with B1=20K and B1=50K and factor...
I got GGNFS to compile on PPC (using lasieve4/generic) after a few source and makefile mods. I want to test it, but I'm running into two problems (with...
Thanks to Sam (trilliwig) for pointing me to source for seq. After getting it compiled I'm running into a problem and I hope someone can point me to the...
Hi Mark, ... getting it compiled I'm ... [--snip--] ... run?. ... $NAME.fb -prel ... This probably isn't going to be much help, but I can definitively say that...
... F7 completed without a problem, but I used factor.sh instead of factLat.sh. Re-running tstS1, I get this output below (which I haven't investigated yet)....
My apologies on the previous post. I think that the build was bad because I didn't recompile all of the sources with -g. (I probably broke make clean when I...
I have more information on this problem. Upon entry to mpz_poly_getComplexZeros, f->degree = 4. The variable n gets that value. In ALG3_6_6_STEP5, n is...
