OpenCL (Open Computing Language) is a framework that allows developers to write programs that can execute across various hardware platforms, including CPUs, GPUs, and other processors. It provides a standardized way to harness the power of parallel computing, enabling applications to run faster by utilizing multiple processing units simultaneously. Designed to be portable and efficient, OpenCL supports a wide range of programming languages, including C and C++. It is widely used in fields such as scientific computing, image processing, and machine learning, making it a valuable tool for developers looking to optimize performance across different devices.
