# Intel(R) Graphics Compute Runtime for OpenCL(TM)

## Introduction

The Intel(R) Graphics Compute Runtime for OpenCL(TM) is an open source project to
converge Intel's development efforts on OpenCL(TM) compute stacks supporting the
GEN graphics hardware architecture.

Please refer to http://01.org/compute-runtime for additional details regarding Intel's
motivation and intentions wrt OpenCL support in the open source.

## Install
Compiled .deb packages are provided on the release page: https://github.com/intel/compute-runtime/releases

## Dependencies

* GmmLib - https://github.com/intel/gmmlib
* Intel Graphics Compiler - https://github.com/intel/intel-graphics-compiler

## Optional dependencies

Below packages are needed to enable [cl_intel_va_api_media_sharing](https://www.khronos.org/registry/OpenCL/extensions/intel/cl_intel_va_api_media_sharing.txt) extension

* libdrm - https://anongit.freedesktop.org/git/mesa/drm.git
* libva - https://github.com/intel/libva.git

## Supported Platforms
