[QUOTE=c10ck3r;339039]Q? about proto-p-1-cuda...
Is the does it write a .bu or .bu2 file like P95 does? If so, are they compatible? i.e. could I run Stage 1 on GPU and Stage 2 on CPU?[/QUOTE]

I believe I read your answer is somewhere in this thread.

EDIT: Or maybe that was on CuLu, I can't remember. :(

About the 1000000009 run, I got to thinking (funny how I do most of that after speaking) that you would need an incredible amount of memory to get that to work, ~4.2GB at the absolute minimum. ~2.4 just for stage 1.

Far beyond my card, but Karl mentioned above he has a 6GB vidcard...

The Titan is the only nVidia Geforce card I think that has 6 GB.

EDIT: That or the Tesla K20X...

there.

Technically, with that binary, we should not be able to use more than 2GB of vRAM and 3-4GB of RAM, for it is 32 bit:smile:
This should be worth mentioning.

another thing :
[code]
M55824233 has a factor: 833043841114609831879 (P-1, B1=839, B2=11550, e=2, n=307

This one has a k of p1*p2*...*839 aand should have been found with a B1 of 839. it doesn't find it. I have to wait till the end of stage 2 to get the factor.

One problem fixed.

Thanks. I guess that was an easy one.

Will there be a new windows build with the stage1 fix in? I have an [URL="http://www.evga.com/products/pdf/03G-P3-1591.pdf"]unusual 580[/URL] that I would be willing to run some tests against.
