The GPU/VPU units have highly specialised functions. They would suck at number crunching (ala folding).

yup, i read that a while ago. GPU have more FPU power for 3d calculations, so it makes sense that it equals a 10ghz P4.

they are designed for 3d calcualtions, so of course they will be great at it, thats like having a press conference to announce that your toaster toasts bread better than your blender

:ROTF: :up: :D

gpus have a much more complex design than cpus though... i bet that if ati or nvidia would develop a cpu it could compete with amds and intels cpus if not beat them...

i really wish i would know enough about compilers to write one and use a gpu as a cpu in an experimental system... :)

nothing to look here, het out of the perimeter of this thread or you will be shot dead on spot.

Wonder what it would take to code a seti@home/folding client to run off the GPU?

Exactly. The design issues you have to deal with are completely different. The graphics chip has to do only one thing... graphics manipulations. It is a floating point powerhouse, but only for very specific, highly linearized operations.

Meanwhile, a CPU, on the other hand, needs to be able to rapidly change what it is doing, as well as run a variety of different programs simultaneously. Different design goals. The idea of using GPUs for floating point math is a good one though, and I even e-mail SETI@home once asking if they ever planned on making a version to run on GPUs. At the time they said it wasn't in the works though :/.

i heard people from the mit are working on it...

and the current gpu development makes modern gpus more and more programmable!

So basically... it takes a 10ghz p4 with their §§§§ty xtreme graphics to even come close to a P4 3ghz w/an FX5900?

what they are saying is, at some calculations a GPU has as much power as a p4 10ghz

Sound card is better for that ;) the Digital signal processing
functions would rip through seti.

do remember some talk in the early years of Seti, might even
have been done?

I want to run seti@home on my CPU, GPU, and SPU (Sound processing unit ;) ) all at once.... :banana: :smileysex :stick:

it will take a coder wich i am but i am not telling anyone. i have to hide from government, they can read our minds with their satellites.

vlad where did you get and look atis inst set i wsa searching for that and couldnt find

saaya
01-26-2004, 05:32 PM
isnt it coded in the dlls?

vlad, why do you think a modern gpu has 1000 pipeline stages?
check out this article about the nv30/nv35 pipeline architecture:

its in german, if you have probs getting it translated into english or spanish let me know :)

This could make an interesting new benchmark for vidcards.. who can crunch a seti/folding unit faster with their GPU? heh.. :D

That would be the §§§§.
