As a non-noob on this, I'd like to see the top post round up both CUDALucas and mfaktc and mfakto, and point to all the required binaries and DLLs/SOs, and source for those of us with non-Windows machines. Binaries for Linux32/64 are OK too...
(Posted from my Windows machine!)

Many answers for the two programs will be in common....

Yes, I vote for Linux binaries. Even if I can get the damn things compiled (a minor miracle) they still generally don't work.

It was always my intention to have two stickies, one for LL and another for factoring. I don't want to make either FAQ too long or complicated. A simple one-pager that lets someone start in 15 minutes. We should leave complex issues such as optimization for the wiki after fleshing them out in the discussion forum. If you guys have any other questions please post them and I'll add them to the top post.

Again, thanks for getting this and the LL version out there, garo. I'm sure it will save beginners a lot of time.

I've now included some special subroutines to get access to more CPU cycles...
No, seriously, I use MS Word 2010 (I'm capable of LaTex and OO). First version was done via a PDF printer (which loses the hyperlinks), second one used MS "save as pdf". That's the difference.
For more details I suggest consulting your local hex editor or MS hotline. I'm too lazy... ;-)

By the way, find attached the original file (only 24 KB)...

followed the guide and created work to do just like prime95. works extremely well on one of my gtx 285. are there any pointers to how to get it to run on my 2nd gpu? tried LLR but it's really difficult with my windows 32bit. perhaps i need to get my other hard drive with 64bit os on it.

Does anyone know the switches available with mfaktc? I saw someplace that -h is one, but no explanation what it was. I got some lower 2^x sequences (got 400M exp with 2^65-2^66) but it seems like they are taking longer than they should due to the screen prints. If there is a switch to shut off the display during these fast runs I think the throughput would be faster. Thanks.

-h is usually prints the help page, though in this case first I'd try going through readme.txt. If it's configurable, it will be explained there. If not, try running -h and see what you get.

mfaktc isn't designed for such short running assignments.
Anyway, perhaps this helps:

Set the Gridsize to e.g.1 and you might want to disable checkpoints for such short running assignment.

Another option: run up to 2^68 or so...
