... 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...
... No, even with higher Q values, my uncle's computer runs as 1.5 times as faster than the dual core put together. Lower Q values yield more of relations. ......
Hi, does anybody tried Ggnfs on a powerpc (970) architecture? I can only get it working for a while and then segfaults. This is the output for tst250: =>"cat"...
... I've built it and run it before on PPC, but haven't applied all of the latest patches. Based upon the error I'm not convinced this is a software issue....
Which version of gcc are you using? Are you running OS X 10.5? Which version of ggnfs? In other words did you check out the latest sources through anonymous...
Greetings All, Where can I get the latest version of GGNFS? Is there as CVS or SVN site set up for all of the mods that people may be doing? Thanks and have a...
... may be ... You can get it either via CVS or by download (CVS is a bit more actually than download) look at http://sf.net/projects/ggnfs Kind regards...
Thanks for the information. I just looked at the files and see that there does not appear to be much development going on as many of the files are many months...
It appears to have found the factorization: Attempt 10 / 50 for: 10599081978368448150849384163124450611852477643836050890843 Using B1=2000, B2=800100,...
I'm sorry, but I was stupid. That was not the factorization. I will look a little further into the problem and see if I can detect the issue. --Mark...
I'm using gcc 3.3.3 on Suse Linux Enterprise Server 9. Kernel version 2.6.5-7.244-pseries64. Latest sources on cvs (anonymous). Thanks PD: Sending again...
I think that the problem is with gcc. I had the same problem on MacIntel, but when I changed src/makefile to use -O2 instead of -O3, the problem went away. ...
OK, I just discovered that I was too hasty with this conclusion. It appears that the last step of make calls "strip" which removes all symbols from the object...
This sqrt bug is the main thing that prompted me to abandon the GGNFS post-processing tools as soon as msieve was capable of finishing the factorizations....
... Totally agree. A fantastic improvement. I use it all the times that I can. Occasionally it complains about not enough rels even if GGNFS is at the end...
... I want to do more than just convert the GGNFS files to msieve and run it. I want to completely replace factLat.pl, so that starting with either a *.n or...
... Several people have asked about this, so I thought I'd throw it out: is it time for a merge between GGNFS and msieve? The latter can replace the majority...

Sounds like a great idea. If you want any assistance, I would be willing to help, although I would do better with getting ports to work correctly than with...
