Little whacky, but get your graphics card to crack?

[TheApe]

OK, I've been up for 20hours staright about now so excuse me if I'm talking absolute b*llocks! I've been thinking whilst cracking the varouse projects we do, what are the possibilities of being able (hyprothetically at least) to get the T&L engine on your graphics card to do RC5 keys? I mean the current nVidia cards T&L engine is pretty usefull at throwing numbers about, if a client could be writen PC's would be able to do Seti in main CPU and RC5 in GPU? am I being stupid or is this at least technically feasable, and if so what sort of keyrate would the GPU get? (EDIT:In theory you could hook into dx8's T&L setup and use this kinda cracker on any card, even without T&L, although this would be unbeneficial? anyone clarify any of this?)

I think the gammaflux team wanted to make a geforce core or something. But I may just be imagining this too, for I too have been awake for 20 hours.

The consensus of opinion is that while a noble and creative thought - The keyrate wouldn't justify the trouble, or the possibility of overheating an expensive vid card processor. I for one, would be a little chagrined to have to replace my GEForce DDR.

On the other hand, Durons are cheap -

I'm not criticizing you - the idea is on the right track = "more blocks"
In practice, you'd be better off to add a crack node. 🙂

I've heared there is a tool out there which is available for Win NT4 and W95 (I believe) which can make use of your GPU. It then looks if you have a multiprocessor system. It's out there 🙂
I don't know if it can work together with the D.net client

Yeah spose so, seemed like a good idea at the time, had 4 hours sl;eep now so it doesnt look all that clever an idea right now.... but hey would be great to see it work, even if it was just from a technology side of things 🙂

i don't see how running rc5 on a graphics processor will overheat it. At best the T&L engine would be used, leaving the 4 graphics pipelines(in the case of Geforce) unused so it would run much cooler than if it were rendering pixels.

I think it was more centered around the cost of effort vs. output.
Crack rack node is cheaper, the software: Klinux is free and readily available.
There are some who would agree it's a tremendous R&D learning experience, but not likely to produce a lot of blocks.

if i had a nickel for every time someone asked this id buy a 900Mhz Duron node and crank that baby up to a great keyrate
