Intro to GPU programming [closed]

Answer 1

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.

Answer 2

Check out CUDA by NVidia, IMO it's the easiest platform to do GPU programming. There are tons of cool materials to read. http://www.nvidia.com/object/cuda_home.html

Hello world would be to do any kind of calculation using GPU.

Hope that helps.

Answer 3

If you use MATLAB, it becomes pretty simple to use GPU's for technical computing (matrix computations and heavy math/number crunching). I find it useful for uses of GPU cards outside of gaming. Check out the link below:
