Intro to GPU programming?

Check out CUDA by NVidia, IMO it's the easiest platform to do GPU programming. There are tons of cool materials to read nvidia.com/object/cuda_home.html world would be to do any kind of calculation using GPU Hope that helps.

I'm not sure of the exact question, but this is what I know. You get programmable vertex and pixel shaders that allow execution of code directly on the GPU to manipulate the buffers that are to be drawn. These langauages ( openGL's GL Shader Lang and gh Level Shader Lang - direct x equiv ), are C style syntax, and really easy to use.

Some examples of HLSL can be found here for XNA game studio and Direct X. I don't have any decent GLSL references, but i'm sure there are a lot around. These shader langauges give an immense amount of power being able to manipulate what gets drawn at a per vertex or per pixel level directly on the graphics card, making things like shadows, lighting and bloom really easy to implement.

The second thing that comes to mind is using openCL to code for the new lines of general purpose GPU's. I'm not sure how to use this, but my understanding is that openCL gives you the beginnings of being able to access processors on both the graphics card and normal cpu. This is not mainstream technology yet, and seems to be driven by apple.

CUDA seems to be a hot topic. CUDA is nvidia's way of accessing the GPU power. Here are some intros.

Take a look at the ATI Stream Computing SDK. It is based on BrookGPU developed at Stanford. In the future all GPU work will be standardized using OpenCL.It's an Apple-sponsored initiative that will be graphics card vendor neutral.

I think the others have answered your second question. As for the first, the " I don't think there is a set standard, but personally, I'd recommend a parallel adder (i.e. A programme that sums N integers).

If you look the "reduction" example in the NVIDIA SDK, the superficially simple task can be extended to demonstrate numerous CUDA considerations such as coalesced reads, memory bank conflicts and loop unrolling. See this presentation for more info: gpgpu.org/sc2007/SC07_CUDA_5_Optimizatio....

CUDA is an excellent framework to start with. It lets you write GPGPU kernels in C. The compiler will produce GPU microcode from your code and send everything that runs on the CPU to your regular compiler.It is NVIDIA only though and only works on 8-series cards or better.

You can check out CUDA zone to see what can be done with it. There are some great demos in the CUDA SDK. The documentation that comes with the SDK is a pretty good starting point for actually writing code.

It will walk you through writing a matrix multiplication kernel, which is a great place to begin.

Try GPU++ and libSh LibSh link has a good description of how they bound the programming language to the graphics primitives (and obviously, the primitives themselves), and GPU++ describes what its all about, both with code examples.

Maybe you will like this GPGPU IDE, which hides unnecessary complexity for general GPU experiments. Currently kernels can be programmed for OpenCL and/or GLSL shaders.

OpenCL is an effort to make a cross-platform library capable of programming code suitable for, among other things, GPUs. It allows one to write the code without knowing what GPU it will run on, thereby making it easier to use some of the GPU's power without targeting several types of GPU specifically. I suspect it's not as performant as native GPU code (or as native as the GPU manufacturers will allow) but the tradeoff can be worth it for some applications.It's still in its relatively early stages (1.1 as of this answer), but has gained some traction in the industry - for instance it is natively supported on OS X 10.5 and above.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
