NVIDIA and CUDA

Is there anyone that used CUDA with nvidia?
I'm starting to study thisand i want to know about thermal problems with nvidia and Cuda at notebooks.
I use a dv6871us.
Thanks for all.

 

Eh, I'm gonna take a wild guess and say heat output would be the same or more likely less than regular gaming. I don't see why it would be any different.

 

cuda works with my dvd player and video editing sofware.
it increases temps for sure but not to gaming levels. in my case it elevates temps to 10-15deg above idle depending on what im doing.
im not sure how it would do with more calculation intensive programs but afaik video rendering is fairly cpu/gpu heavy

 

I've been using CUDA to accelerate decoding of h.264 and .m2ts, and I have to say it does a bang up job. I can play full HD 1080p at about 20-24mb/s to my tv and do pretty much anything else I want to do while it's playing without anything slowing down or even any minor stuttering. I used to get around 20-30% cpu utilization but now it's down to about 5-10 percent. But heat output doesn't really change, just normal temps outside of gaming.

 

I have a benchmark thread here with one version being CUDA specific (there are also AMD/Brook versions for ATi users). From my experience this pushes the GPU to the envelope, I've seen temperatures on par with running Furmark. It definitely generates a lot of heat, but that utility fully utilizes the GPU. Many CUDA enabled apps utilize the GPU, but not at 100% load.

 

I haven't seen CUDA before in my life untill I got a folder today with a MEDION laptop using nvidia cuda. Is there anything special about cuda?

 

^The most common end-user usage is to accelerate H.264 video, similar to DXVA but without the limitations. It has plenty of other uses, however.

 

CUDA is the usage of the SIMD (Single Instruction Multiple Data) instructions for highly parallelized computations by using the GPU which is highly optimized for parallel computation to compute.
CUDA is suppose to include general processing instruction/libraries so it is easier to program the GPU.

 

and how do u use CUDA to accelerate HD video playback and all?

 

You need a video codec that supports CUDA, such as CoreAVC. The newer versions of Media Player Classic Homecinema support GPU acceleration with it's own internal codecs using DXVA instead.

DivX 7 also does a limited amount of GPU acceleration automatically.

 

Not just to decode H.264 video, but encode it. Badaboom, MediaCoder, and TMPGEnc all have CUDA-enabled encoding that can blaze past CPU-only programs. Not always in image quality, but still...

(fyi, I'm getting ~30fps encode at 480p, ~12fps at 720p, and ~6fps at 1080p on Badaboom)

 

Such uses (or rather, implementions in applications) are slated at places like Doom9 though, mainly because of the aforementioned quality issues.

 

Also true, but I only have a 16" screen to watch content on. I don't have a full day to let my Core 2 Duo work in seconds-per-frame to encode video that might look a little bit better.
