Raspberry Pi

[SupremeSpod]

Mine has just arrived, didn't know they were that tiny!

Anyone worked out anything exciting to do with it? I was planning on sticking an HD video on it, oohing and aahing for 5 mins then sticking it away in a drawer somewhere to be rediscovered when we next move house - does that sound about right?

Edited - going to get my eldest to build a cool lego case for it too.

I play "Scott Adams' The Count" via ssh on mine.

And I've finally got an SDL surface running without X.

Not really a fair post that, for a couple of reasons.

Firstly, AtW thinks he's right and hitting the little fat f*cker repeatedly in the face with a spade with the facts of the matter engraved on the blade will not change his mind.

Secondly, it's going to be a bloody long time before Broadcom release enough information on the graphics cores in the Raspberry Pi before either CUDA or OPENCL etc are supported/available.

If you really want to you can do computation on GPU without CUDA et al, I think people doing just that proved the usefulness and in fact drive CUDA in the first place (though maybe not).

Not on a Raspberry Pi, the interfaces have not been released to the public. Broadcom are very tight-lipped about their architecture at the moment.

If you can prove otherwise I'll gladly doff me cap and pinch your example code.

Doesn't it support OpenGL? Isn't it a case of abusing the openGL APIs to shoehorn your calculations into the graphics pipeline? I thought this sort of behavior was what started the whole GPGPU ball rolling and gave rise to CUDA / OpenCL in the first place.

Nope, it doesn't support OpenGL, it supports OpenGL ES 2.0 - have a look.

Do you know what instructions the GPU cores use and how they're driven?

Just asking like, 'cos if you do, I'll gladly doff me cap and pinch your code.

NVIDIA and ATI were very open about their architecture, even modifying it in certain cases to make it more "accessible".

Broadcom currently won't and to be honest, if I had a shed load of patent pending stuff inside that chip, neither would I.

I meant old-school GPGPU, i.e. cramming your data into textures and writing shaders

No, OpenGL and OpenGL ES 2.0 are fundamentally different, although very similar in most ways so you can think of ES2 as a subset of GL when writing code.

Btw, I have another Pi arriving Week commencing ~2nd July anybody want it? Was going to put it on EBay (and speculate) but if you're interested you can have it for what I paid (£30 + whatever it costs to get it to you) - If you're lucky I'll throw in an SD with Debian on it for you.

Please PM if interested.

You also registered for both sites then? my first and second are both enroute.

Borderline "Synthetic programming"? You have a point. Truthful answer, I don't know.

I think the OpenGL ES 2.0 library and driver is supplied by Broadcom and short of reverse engineering that...

This might open a few trapdoors...

Of course I did.

I've decided I'm going to keep the spare, order a new one and call them "Huey, Duey and Louie" - care to guess why?
