Sorry if this has been answered in the ggnfs FAQ somewhere or other, but if it has I'd appreciate a clue or two :-) It's the old "horribly wrong", "column a =...
I've found that that I have random matrix problems at times when maxrelsinff is set to 0 in factLat.pl. At times when there are barely enough relations to...
... Thanks Greg. I can't remember when I last played around with $maxRelsInFF in factLat.pl - probably over 12 months ago. No obvious benefits (long...
I faced this probelms many times, and found out that this happens beacuse some duplicates are still in the processed data (rels.bin's).The soloution is dump...
... Thanks, Raghu. I didn't try dumping and re-processing - I've tried that many times in the past and the results are quite random. Sometimes they work but...

Hello, a> Hi, I'm trying to factor a self-generated rsa512 to test some things. You are trying to factor VERY hard number (for GGNFS). If you want "to test...
... things. ... I've tested some 100-120 digits and they worked great (with a single core and 1-7 days of workload) Does snfs could do it easily? ... found a ...
Hi, I've tried to build ggnfs-0.77.1-20060513 on an Opteron but ran into a problem: procrels crashes with a segfault. This apparantly is due to the mremap()...
I'm not up to trying to use ggnfs yet; I just want to understand how various parts of NFS work. For example, I'm fuzzy on whether SHARK is mostly the same as...

Hi, I am trying to factor a C130, and have found that matsolve is not behaving itself (or, perhaps, the relations I found were not very good). After matsolve...
... Thanks. I think that I will try reprocessing the relations. I have in the past had a little trouble with that: I change the ALIM and RLIM values, this...
In my experience, you just need to sieve a little more. In factLat.pl, is maxrelsinff set to 0? If so, that often causes it to stop sieving too early....
Another idea ... this also sometimes happens if you've sieved too much as well and matprune is significantly decreasing the size of the matrix. If you...
Hi, I'd like to thank you for the responses to my recent enquiry. I tried the suggestion of modifying the alim and rlim values by a small amount to force...
First of all, Hi! I'm new to this group, but have been factoring (with ecm) since about erm... 10 years. Now I've discovered how to compile a bit, and got...
On 28 Feb 2007, before you help me with the NFS questions, I thought I will help you. In the aliquot 9852, in the iteration #973, where you left over with the...

Hello Micha ! If I am not wrong, I have first used ggnfs to factorize smarandache sequences composites using your tables as a basis... ;-) ... It seems ok to...
No problem. Can somebody please reply for the following questions: How can we run GGNFS in many computers for both sieving and matrix solving? Is it correct to...
Hello everyone, I've been successfully factoring numbers with GGNFS for a long time now and am always impressed with its performance. However, I've recently ...
