Welcome.
I am sure that you have visited this site http://www.nvidia.com/object/cuda_home.html;
You can get CUDA from http://www.nvidia.com/object/cuda_get.html.
And you should ask Mr Google Or Mr Bing for more information about CUDA.
It has a mass of threads on this forum to discussing about your attention.

GPU stands for Graphics Processing Unit…

CUDA tries to make GPU stand for General Processing Unit by exporting graphics-independent programming model to an application developer – Thus, application programmers can offload compute intensive sections to GPU for faster processing.
