OpenCL is described as 'An open, royalty-free standard for cross-platform, parallel programming of diverse accelerators found in supercomputers, cloud servers, personal computers, mobile devices and embedded platforms' and is an app in the development category. There are three alternatives to OpenCL for Windows, Linux and Web-based. The best OpenCL alternative is NVIDIA CUDA, which is free. Other great apps like OpenCL are ZLUDA and AMD ROCm.
Parallel computing platform and programming model for accelerating applications on GPUs, supporting development in multiple languages, offering a toolkit with libraries, compiler, development tools, and runtime for enhanced performance in scientific and research tasks.
ZLUDA is a drop-in replacement for CUDA on non-NVIDIA GPUs. ZLUDA allows running unmodified CUDA applications using non-NVIDIA GPUs with near-native performance
ROCm is an open-source stack, composed primarily of open-source software, designed for graphics processing unit (GPU) computation. ROCm consists of a collection of drivers, development tools, and APIs that enable GPU programming from low-level kernel to end-user applications.
