Hi, I've just discovered this interest group. I've had a healthy interest in integer factorization for a long time now. I do regular trial factoring for the...

... Thanks for the clarification. ... I am certainly after the latest versions. SVN is new to me, I'm reading up on it now at SourceForge. Looks like I need an...
... Thanks Serge, that is a great tip and a very useful feature on SourceForge to be able to download the latest tarball like that. I've just compiled GGNFS on...
Hello all, Just wanted to let you all know that I finally plan to release a beta 1.0 version of GGNFS in the near future. The post-processing changes are all...
This is great news! Bruce Dodson and I have been recently factoring Cunningham targets with SNFS difficulty around 260-265 digits. Msieve's threaded block...
Hi. some months ago someone requested a Windows build here in this group. I provided a SVN build but now it is outdated and possibly not as fast as the newer...
where do you get those x64 files? I built matbuild using binaries with visual studio 2005 in x64 mode and still was limited to 2gb max matrix size. (mine...
... and ... Windows version didn't work for me. I built matbuild using openSUSE 11 x64. You can remove singletons before using original matbuild. Maybe it ...
... That's a very impressive job, but your matrix was incredibly dense! Would it be possible to rerun the filtering using msieve to see how large and dense the...

... I was mistaken, C168=pp84*pp84 ... I'll definitely try it and post results. About a 1.5 years ago, msieve doesn't support so big factoriazations....
... Maybe I need to process original unique ~130M relations with lower factor bases? All rels finded while sieving with RFB/AFB: 21M/20M. Then FB increased to...
... (I'll be R.D.Silverman's voice in this thread.) What was this number? Why... waste... so... much... time... on a synthetic number?!! Why not factor a...
I tried postprocessing with msieve a project that wasn't ending with ggnfs. I did everything correctly about the worktodo.ini, the msieve.fb and the msieve.dat...

... Right! Kamada's collection is good - you can solve a GNFS-168 there as well (there is one!), but my math friends tell me that this is like stamp...
... Sasha! Now I have finally put 2+2 together. That's you! Glad to meet you on the internet. Well - as you can see - Kamada's collection has huge holes in the...
Thanks, that worked! I just threw out some of the rels.bin.x files and dumped again to get about 42m rels. postprocessing seemed to work that time ... ETA 89h ...

Indeed, that is pretty dense. This is one of the things that I'm doing right this time around, with the new release. I'm rewriting all of the post-processing...
