What is CUDA?

CUDA, or Compute Unified Device Architecture, is a parallel computing platform and application programming interface (API) model created by NVIDIA. It allows developers to utilize the power of NVIDIA GPUs for general-purpose processing—an approach known as GPGPU (General-Purpose computing on Graphics Processing Units). CUDA provides a C/C++ language extension that enables developers to write programs that execute across various cores of the GPU.

The main advantage of CUDA is its ability to perform parallel computations, which can significantly accelerate the processing of large data sets and complex algorithms. By distributing tasks across thousands of GPU cores, CUDA can achieve performance levels that are unattainable with traditional CPU processing.
