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.

Programming standards for parallel computing include OpenCL (vendor-independent), OpenACC, OpenMP and OpenHMPP. As of 2016, OpenCL is the dominant open general-purpose GPU computing language, and is an open standard defined by the Khronos Group.
It offers several programming models: HIP (GPU-kernel-based programming), OpenMP (directive-based programming), and OpenCL. ROCm is free, libre and open-source software (except the GPU firmware blobs [4]), and it is distributed under various licenses.
OpenCL program execution flow. The following figure illustrates the execution flow of launching an OpenCL program on a GPU device. The CPU first detects OpenCL devices (GPU in this case) and then invokes a just-in-time compiler to translate the OpenCL source code into target binary. CPU then sends data to GPU to perform computations.
OpenCL is widely used for parallel programming across various hardware types, while Vulkan primarily focuses on high-performance graphics and computing tasks. [ 39 ] SYCL, on the other hand, is the high-level single-source C++ embedded domain-specific language (eDSL).
Clang (/ ˈ k l æ ŋ /) [6] is a compiler front end for the programming languages C, C++, Objective-C, Objective-C++, and the software frameworks OpenMP, [7] OpenCL, RenderScript, CUDA, SYCL, and HIP. [8] It acts as a drop-in replacement for the GNU Compiler Collection (GCC), supporting most of its compiling flags and unofficial language ...
Metal combines functions similar to OpenGL and OpenCL in one API. It is intended to improve performance by offering low-level access to the GPU hardware for apps on iOS, iPadOS, macOS, and tvOS. It can be compared to low-level APIs on other platforms such as Vulkan and DirectX 12.
