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 open source.

Supported Platforms

• Intel Core Processors with Gen8 graphics devices (formerly Broadwell) - OpenCL 2.1
• Intel Core Processors with Gen9 graphics devices (formerly Skylake, Kaby Lake, Coffee Lake) - OpenCL 2.1
• Intel Atom Processors with Gen9 graphics devices (formerly Apollo Lake, Gemini Lake) - OpenCL 1.2
• Intel Core Processors with Gen11 graphics devices (formerly Ice Lake) - OpenCL 2.1
• Intel Core Processors with Gen12 graphics devices (formerly Tiger Lake) - OpenCL 2.1

Release cadence

• Once a week, we run extended validation cycle on a selected driver.
• When the extended validation cycle tests pass, the corresponding commit on github is tagged using the format yy.ww.bbbb (yy - year, ww - work week, bbbb - incremental build number).
• Typically for weekly tags we will post a binary release (e.g. deb).
• Quality level of the driver (per platform) will be provided in the Release Notes.

Installation Options

To allow NEO accessing GPU device make sure user has permissions to files /dev/dri/renderD*.

Under Ubuntu* or Centos* user must be in video group. In Fedora* all users by default have access to /dev/dri/renderD* files.

Via system package manager

NEO is available for installation on a variety of Linux distributions and can be installed via the distro's package manager.

For example on Ubuntu* 19.04, 19.10:

apt-get install intel-opencl-icd

Procedures for other distributions.

Linking applications

When building applications, they should link with ICD loader library (ocl-icd). Directly linking to the runtime library (igdrcl) is not supported.

Manual download

.deb packages for Ubuntu are provided along with installation instructions and Release Notes on the release page

Dependencies

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

Optional dependencies
