I managed to solve this problem by downloading the sourceforge newer version, it took 8 times less relations (5 mil special Q instead of 40mil) to get a very...
patch against latest CVS at http://tech.groups.yahoo.com/group/ggnfs/ files/procrels_sieve_factLat.diff.gz procrels.c: - added code to load/save (a,b) list and...
I wonder if someone could help me with the above, please? [Tiger 10.4.X, gcc 4.0] Firstly, the latest version of the source I seem to be able to find, is...
I have downloaded ggnfs, and MinGW, which I was told was needed for compiling. Because I have very little programming experience, is there a step-by- step...
I read this post with interest, in reference to _my_ recent request for help. But tell me, please, Hans - how do I obtain a CVS username/password? [the...

Hi, I had several problems with matbuild/matprune/matsolve and I think I have figured the problem. I'm using a 64 bits computer and every time I tried to...
Great! (After some experimentation) I've successfully downloaded the source anonymously (roughly as per OP). I'm doing a "make ppc_970", and it starts to...
IIRC correctly (since I did the port a long time ago), getline() is not in one of the gcc librarieson PPC. I haven't looked in a while, but isn't there a ppc...
Hi Mark, Thanks very much for your response. I've been looking, and can't _see_ anything like that (eg at http://ggnfs.cvs.sourceforge.net/ggnfs/branch_0/src/ ...
Fantastic! I think I've got it... [and what's more it appears to work correctly for the larger inputs, which was my original problem on ppc! :)))] I had to...
... I have downloaded MinGW, but I don't have any .exe files I thought I would be using to compile ggnfs. Even on the start menu, I only have a webpage link,...
On Saturday, I got a doubt if the speed of my sieving was getting reduced because I have set up a high value for skew. (1) What is skew? (2) What consequences...
... For a polynomial f(x)=c_d*x^d + ... + c_1*x + c_0 use a skew of ... to find the optimum. For example, if f(x)=12703*x^4-1, use skew |1/12703|^(1/4)=0.094 ...
Never mind that Mr. Jason has already replied for that to me up. Regarding 6,305- I currently have 3205481 full relations. The number of full relations needed...
On 10 Nov 2007 afternoon, I went to my uncle's house and started running GGNFS sieving for 6,305- in it. I found that the speed of sieving in that 3.06 GHz...
Hello there, Sieving speed depends on number of factors, including size of problem, quality of polynomials, sieving methods in use and more. So if you'd like...
... Mine is Pentium D 2.8 GHz dual core, my uncle's is Pentium 4, at 3.06 GHz. ... Yes, indeed matbuild always asks so only for 4866763 FFs. Let me see these...
Various reasons why two systems may differ in sieve speed: 1. As the Q increases, the speed of sieving slows. To compare speeds, you really need to sieve the...
