Hi, I am using Jason's implementation (msieve) modified to use GNFS with short numbers (<20 digits, knowing that it's inefficient for these cases). When I...
... msieve only chooses degree 5 polynomials, and so many things would have to change in order to accomodate very small inputs that it's not worth the effort....

Could someone please send me binaries for "make prescott" of GGNFS for x86 (non-cygwin dependent)? I currently do not have access to an environment where I can...

It does work on PPC as I have built and run it (besides I wrote the PPC specific asm routines). If you follow the thread you will see that it died after I...
thank you very much! but I just realized I misidentified my cpu and don't have sse3 :( instead I need "make pentium4" for sse2 if this could be provided I'd be...
Hi all, I've posted factMsieve.pl to the files area. It is a conversion of factLat.pl to use msieve for the postprocessing. It is very much a work in...

... Thanks for the posting. I realize that it's still in a raw state, but I think it will prove of value. I'm currently working on a 149-digit GNFS job and am...
... If you haven't saved the relations in text format, then dump them using procrels -fb <name>.fb -prel rels.bin -dump Then concatenate all of the spairs.dump...

Having a devil of a time trying to get this to work without errors. It appears to collect enough (just over 2.8m) relationships to be able to launch MSieve the...
It appears that the problem is related to the second column of the relationships. Up until the errors beginnning, the second column is gradually incrementing....
The relations with b (the second column) in order are from the classical sieve. Those with b out of order are from the lattice sieve. msieve doesn't care...

It was a bug in factMsieve.pl. The algebraic coefficients were being truncated to 64-bits when the .fb file was created. I didn't see since I only tested...
Not a problem. My factoring is a hobby, not a crucially important task. Consider it as beta-release testing of your tool. Thanks for resolving the issue. ... ...
I tried to use your script to complete a factorization started by factLat. There were already enough relations, but with your script, it tries to sieve...
Mark, The script doesn't support directly resuming a factorization already started with factLat.pl. However, you can get it to work. Here's how, copied from...
I followed your steps, but have a similar problem. Here is the output: Total yield: 79996 0/0 mpqs failures, 7584/4116 vain mpqs milliseconds total: Sieve...
It seems like it still trying to continue a factorization started by factLat.pl rather than starting a new one. Did you use a different directory? 11002690...
