Nvidia CUDA

Hi

First Time Post

My question was is there any programmes that can use CUDA e.g folding@home / SETi type programmes or anything at all able to use CUDA

thanks guys

Welcome to AT

What's CUDA?

its a way nvidia have opened up their gpu for use by programmers who can now write programmes to run on nvidia cards just wondered if anyone like folding@home (or any other people) have decided to use this method. would love to be able to run SETI or other things on my gpu

Folding@home has a GPU client for some of the ATI cards.

Here is some info in the Folding@Home GPU CLient FAQs:

What about video cards with other (non-ATI) chipsets?
The R580 (in the X1900XT, etc.) performs particularly well for molecular dynamics, due to its 48 pixel shaders. Currently, other cards (such as those from nVidia and other ATI cards) do not perform well enough for our calculations as they have fewer pixel shaders. Also, nVidia cards in general have some technical limitations beyond the number of pixel shaders which makes them perform poorly in our calculations.

currently, according to gpgpu.org, this is a list of known entities who are working on using gpu's to accelerate processing.

tho, it still does not specify if anyone is specifically using nvidia hardware/cuda.

I am waiting for somene else to come out with a program that harnesses gpu power(besides folding@home), but till the gpu itself uses double precision point accuracy, using the gpu may not be as attractive for researchers.

Though I could be mistaken ,I think that info is out of date in that it was published before the 8800s were released.Having said that AFAIK the GPU clients still don't support the 8800s ,from what little I know.

This reminds me ,its probably cool enough now that I can run the GPU client on my 1950

thanks for your answers guys

on the point of double precision the new nvidia cards in the next update/release will support this as its a known flaw with the design if they want it to be used for this type of processing

after that then maybe more people will support gpu based processing on nvidia cards but it will mean i have to upgrade


i would like to see folding@home support the new ati/amd 2900 series cards which on there site they say they are working towards as i think these will be amazing cutting though work units soooo fast 320 stream processors in the top model i think (edit: and also higher internal bandwidth)

thanks again for replying
