CUDA™ is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).

With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA.

CUDA is a parallel computing platform and programming model that makes using a GPU for general purpose computing simple and elegant. The developer still programs in the familiar C, C++, Fortran, or an ever expanding list of supported languages, and incorporates extensions of these languages in the form of a few basic keywords.

These keywords let the developer express massive amounts of parallelism and direct the compiler to the portion of the application that maps to the GPU.

A simple example of code is shown below, written first in plain “C” and then in “C with CUDA extensions.”

Learning how to program using the CUDA parallel programming model is easy. We have webinars and self-study exercises at the CUDA Developer Zone website.

In addition to toolkits for C, C++, and Fortran, there are tons of libraries optimized for GPUs and other programming approaches such as the OpenACC directive based compilers.
