GPU CUDA programming

HI there,

I'm wondering if anyone has knowledge with GPU programming using CUDA.

1-As i know, Panda Board has GPU, so what about programming this unit?

2-Also, I'm thinking about nVIDIA GPUs but i saw lots of very heavy cards on their website,i do believe it will provides great processing power with low anticipated power consumption if it is used on UAVs to make feature extraction and feature matching as an example of high computation requirements ,did anyone try it for Quadrotors or any x-rotor ?

3-And if so what is the recommended GPU board ?

 

Any opinion is more than appreciated,

Thanks in advance

I'm pretty sure that the panda board (looks similar to the beagle board) doesn't work with CUDA, which I believe is nvidia only.  Its possible that it will work with OpenCL, but I'd be a bit surprised there too.

 

When you have an actual nvidia GPU installed, OpenCV has a lot of stuff that is optimized for it, for your imaging needs:

Well, second part is right :) ...

OpenCL on PB

But i can't  believe it... it is not mentioned on PB site that it supports OpenCL !! ...

Wow. I was shocked to see that, but after a bit of further investigation, it seems that the company is officially supporting it:

That said, I'm still somewhat skeptical (or possibly cautiously optimistic), and would really like to see some performance numbers.  OpenCL support itself isn't hard, I believe there is a platform independent reference implementation, which they could have just ported here to put a check in their feature matrix.  On the other hand, this is obviously something that is very useful for embedded applications, so it would make sense for them to invest in getting a good SIMD setup going on their hardware.

"we will release an OpenCL SDK as soon as an OpenCL enabled platform with our technology is available.The availability is dependant on our customers and we cannot release an OpenCL SDK earlier.
We will make an announcement as soon as the OpenCL SDK is publicly available.

Thank you for your understanding,
Best regards," said by Imagination Technology support

 

I'm wondering how did this guy manage to make it works !!

One option is to use OpenES on Pandaboard, bud i don't have any previous experience with it so may anyone give a hint about it on PB? ... till openCL is officially supported on PB
