Hi All, I downloaded the ggnfs executables from SourceForge a few weeks ago and was quite pleased to find that they worked perfectly, after I'd got factLat.pl...
For General NFS factorications, in which the polynomial selection tools are used to find a polynomial, these times are expected. The 8 hour C119 used Special...
... No, it was a GNFS factorization, see the log below. Somehow something went wrong with the timings. A negative sieving time for instance. Regards Sander ...
Ah...you're right. I wasn't paying enough attention. I just going on that 8 hours is about right for a C119 SNFS, but FAR too little for C119 GNFS. Sorry. ...
Hi, I dont anything about GGNFS and the some of the guides i looked at seem very advance. I have downloaded the Windows version of GGNFS and i have the key i...
Hi, Yesterday i ran into a few small problems with importing relations from another pc. I had done all (actually way to much) sieving on one pc on which i'm...

Hi, I'd like to thank those who responded to my previous enquiry. I hadn't even noticed the negative time in the ggnfs.log that was posted! Anyway, the c122...
I think the simple answer is using multiple. The majority of time is generally spent sieving. Distributed this portion across a network of 10 machines, 120...
Recently I am reading the programe entitled gnfs-lasieve4e.c which is included in the software of ggnfs.But the sieve thresholds puzzle me.So I ask for help...
Hi, I've been using 0.77.0 to factor GNFS numbers up to about C120. I've done black box approach only, i.e. factLat.pl, letting the script figure out all...
... I have a very good experience with the current snapshot. It is contiously running on 3 systems, and every composite so far have work perfect. Currently I...
... Do you mean the sieve_threshold variable in the lattice siever source? This looks like the log value that bytes out of the sieve must achieve before trial...

Using 0.77.0 on a GNFS C120 and grepping ggnfs.log for FF: [12/22 02:20:35] rels:7116912, initialFF:0, finalFF:551926 [12/22 04:01:06] rels:7260693,...
... The drop occurs the first time the finalFF reaches the requested target. At that time GGNFS starts to reduce weight by dropping ff:s with high weight. In...

Have you used parallel sieving on some independent computers? I think, you have two relations 'glued' into one... You can try to find and erase manually the...

... No, I've only been using 1 machine for sieving. What did happen however is that I ran out of disk quota, so file rels.bin.0 may be corrupted. In fact,...
