OpenCL™ defines a C-like language for programming compute device programs.Alternatively, you can view the source for the C++ bindings to see what underlying OpenCL™ function is used, and with what arguments by the particular C++ binding. See the OpenCL™ 1.0 specification for the corresponding C API. In this and subsequent tutorials, I use the C++ bindings exclusively and describe OpenCL™ in these terms. Currently, there are several efforts to develop bindings for other languages (see the links at the end of this article), and, specifically, there has been a strong push to develop C++ bindings.

OpenCL™ specifies a host API that is defined to be compatible with C89 and does not make any mention of C++ or other programming language bindings. Here are some notes of caution on how the OpenCL™ samples are written: Using platform and device layers to build robust OpenCL™.I hope to follow up this first tutorial with additional ones covering topics such as: The following 'Hello World' tutorial provides a simple introduction to OpenCL™. If this is the case, please let me know via our Stream Computing forum, and I will do my best to rectify the code and publish an update. I have done my best to provide examples that work out-of-the-box on non-AMD implementations of OpenCL™, but I will not be testing them on non-AMD implementations therefore, it is possible that an example might not work as expected on such systems. All examples are written in pure OpenCL™ and should run equally well on any implementation.

I work at AMD, and, as such, I will test all example code on our implementation for both Windows® and Linux® however, my intention is to illustrate the use of OpenCL™ regardless of platform.

This article helps make OpenCL™ easier to understand and implement. OpenCL™ is a young technology, and, while a specification has been published ( there are currently few documents that provide a basic introduction with examples.
