How to start?
Hi, I (and hopefully many others) am interested in this project and how to help, but I'm not a matematician and I think this project sort of lacks instructions. I would be happy to add this project to my collection of guides, but that requires that I understand it, which I don't.
What program to use? How? Stuff like that. I guess this isn't as easy as opening prime95 and pressing start, but is this project pro's only? Or can newbies (both to math and the project) participate as well? Thanks OH

Actually, "factoring" is no single project, but devoted to all factoring efforts in general.The biggest factoring project is the cunningham project, which tries to completely factor numbers of the form k*b^n +/ 1, currently with b =< 12 and k s.t. the number is upto ~360 digits.

Just a starters question! If I have a computer with alot of memory+ disk space but a slow processor, is a method of factorization recommended. Is there a project that uses this method of factorization?

If you mean step by step instructions, no. However, a person should be able to use GMPECM instructions to start running curves on these tables. The objective of the tables here is to show how many curves need to be run at each level.
Are you planning to write a newbie FAQ?

But are you guys using ECMNET?? I'm not wholly sure about what GMPECM is... Last fiddled with by OmbooHankvald on 20050803 at 16:13

And, may I add, I don't know anything about how to compile stuff so I'm looking for precompiled binaries. I've downloaded ECMNET , but it was missing the exe's, then I downloaded GMPECM , but it only contained a bunch of .c files (and I'm neither good at math nor programming).
The only somewhat usable ECMthing was from ElevenSmooth . But where do you get yours??? OH

Try the GMPECM6 released thread in Factoring>GMPECM. There are several binaries on pages 2 and 3. GMPECM does not have to be used with ECMNet just like Prime95 does not have to be used with Primenet.

Okay, I've compiled my very own ecm.exe but now I only need the ecmclient.exe, how do I get/make that?

The XYYXF project has a precompiled binary available for download. You'll find it at http://xyyxf.at.tut.by Look for it under Reserve, Choosing Methods.
