CUDA - What is it?

post #1 of 9
Thread Starter 
What exactly is CUDA? I've been looking it up for a little while now and I'm still confused on some fronts. Do the new video card drives just automatically come with it or is it something you have to download separately? What's the CUDA Toolkit for? How do you know if you have it enabled or disabled?

Its a shame this has been ignored for 10 minutes

If you havent looked it up cuda stands for Compute Unified Device Architecture..

Complicated? Basically it means that the architecture was designed to be able to compute more then graphics data.

Only Nvidia Cards have CUDA technology. You need to download the latest Nvidia drivers to get the latest version of CUDA.

The CUDA tool kit is for developers.

CUDA cant be enabled / disabled. Look at it as another CPU. if your not using it, it is idleing. Turning it off means disabling the video card.

If you're curious as to the reasoning behind the use of the word 'unified' in this acronym, check out this explanation:

http://www.pcper.com/article.php?type=expert&aid=319

CUDA is actually something that's been around since G80, but they only started calling it CUDA a year or two back.

Alright, thanks for that information it was helpful. By the way, what exactly is purevideo? Is that something built into the drivers as well like CUDA?

average joe doesn't use it
unless he is unaverage joe who has some kind of software which uses cuda
like badaboom for example (there are more programs but they are all basically prefessional programs)
http://www.badaboomit.com/
so basically all we need now is more software that anybody can use, and not only professional programs

Hopefully there will be an Anti-Virus program uses CUDA to increase scan speed soon.

Scan speed is usually bottlenecked by the Hard drive..


Truth is there is some other software that uses cuda for like Centralizing video and removing blurr ETC ETC.

PureVideo is hardware acceleration for video. AMD version is called UVD.

These off-load video decoding from the CPU to save power and CPU cycles.

If you have an application that supports CUDA, then you can use it.


CUDA is really interesting for science, finance, math, etc. It allows for easier GPGPU development and allows people to basically to run a supercomputer for $500.
