Hi, Can somebody do me a favor and send me a P4 Win32 binary of the latest version of matsave? I'm really in need for the autosave function. It's hard to...
Finally, after years of trying to puzzle out how modern polynomial selection for NFS worked from code alone, now there's a paper by Thorsten Kleinjung: ...

I hope you got a working binary OK. If memory is very tight then it may be best to use quite a long period between saves, 8 hours or more. The save file is...
It doesn't matter if an operation is done is background, foreground or middleground. A CPU operation takes X time, which is taken away from computing operation...
... Plenty of RAM. 12GB :-), but saving a couple of times a day is ok, as long as i don't loose over a week of work. I did get a binary but didn't get to test...
Hello, Jason! ... Access to file is restricted. Can someone please download the file and email it to me and/or put it in the 'Files' section? -- Best Regards, ...
The save file is created by writing a block of memory that matsolve is continually updating. The matsolve process can't update that memory until it has first...
Has anyone else had a problem with the lattice sieving failing on Power ? I get an error of the form: TD sieve on side 0: 18379 does not divide The code is...
Kleinjung's paper is loaded in the Files - papers section. He uses a clever trick to create nonmonic linear polynomials to speed things up, combining this with...
... For what it's worth, Bob Silverman believes this will be quite difficult, and the two cubics won't have a higher yield than base-m polynomials unless the...

... I have read the paper above. The crux seems to be that they manufacture a basis that lets them run through the basis pairs linearly, and hence they can...
While installing GGNFS by MinGW, I encountered the following problem Tuch@HOME-Q81RIDVXCJ /home/ggnfs $ make echo "#define GGNFS_VERSION \"0.77.0\"" >...

Nay.... For Mr. Philippe, I am using MinGW. Pentium 3 is really what I am using. I checked up. You can see that for Athlon-XP too makes no difference of the...
... Whats so bad about the product? You better use msieve to factor numbers < 100 digits. An 84 digit number shouldn't take that long. ... This is a bad plan....
I've been using the precompiled binaries to do factoring. Note: Since the precompiled binaries are only the executables, I had to download the entire source...

... The changelog has something about GMP 4.2; apparently there's a GMP_BUG makefile variable you have to set, at least in the July snapshot. No idea if it's...
