What is OpenCL?

OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators. OpenCL specifies programming languages (based on C99 and C++17) for programming these devices and application programming interfaces (APIs) to control the platform and manage memory. It enables parallel computing using a platform-independent programming model.
