Deploy OpenCL™ Runtimes

Obtain runtimes to execute or develop OpenCL™ applications on Intel­® Processors

Important Change 

There is a change in OpenCL™ CPU runtime for Windows* distribution in the 2020 February release to be consistent with Linux* distribution. The OpenCL CPU runtime is removed from the OpenCL driver for Windows starting in the 2020 February release version "igfx_win10_100.7870.exe".

Intel® Graphics Technology Runtimes

Execute OpenCL™ applications on Intel® Processors with Intel® Graphics Technology.

  • Specifically target Intel® HD Graphics, Intel® Iris® Graphics, and Intel® Iris® Pro Graphics if available on Intel® Processors.
  • Runtimes for Intel® Graphics Technology are often deployed in tandem with an Intel® CPU runtime.
  • Consider graphics runtimes when developing OpenCL™ applications with the Intel® SDK for OpenCL™ Applications or Intel® System Studio.

6th Generation Intel® Core™ Processor Example

Check release notes to ensure supported targets include your target device. For Intel® processors older than supported targets, please see the legacy deployment page.

Linux* OS

Repository Install Guidance *Easy* | Manual Download and Install | Build | README | FAQ

Intel® Graphics Compute Runtime for OpenCL™ Driver is deployed with package managers for multiple distributions. Please see the documentation on the GitHub* portal for deployment instructions.

Considerations for deployment:

  • Ensure the deployment system has the (libOpenCL.so) ICD loader runtime from either:
  • The Intel® Graphics Compute Runtime for OpenCL™ Driver depends on the i915 kernel driver. Necessary i915 features are available with relatively recent Linux* OS kernels. The recommended kernel is the validation kernel cited in documentation. In general, deployments after the 4.11 kernel should be OK. Make sure to review the release notes and documentation for more specifics.

 

Windows* OS

  • Intel® Graphics Compute Runtime for OpenCL™ Driver is included with the Intel® Graphics Driver package for Windows* OS.
  • Download Options
    • System Vendor
      • See your vendor website for a graphics or video driver download for the system
    • Intel® Download Center
      • Navigate to “Graphics Drivers” for recent releases.
      • Try the system vendor first in consideration of vendor support. System vendors may disable Intel® Graphics Driver install.
    • Intel® Driver Update Utility
    • The graphics driver package is built in with Windows* 10 OS install. However, the built-in default deployment may not contain latest features.
  • Release Notes
    • In the Download Center navigate to “Graphics Drivers” for Release Notes.

Intel® Xeon® Processor OR Intel® Core™ Processor (CPU) Runtimes

Execute OpenCL™ kernels directly on Intel® CPUs as OpenCL™ target devices.

  • Consider an OpenCL™ CPU implementation for Intel® systems without Intel® Graphics Technology.
  • Systems with Intel® Graphics Technology can simultaneously deploy runtimes for Intel® Graphics Technology and runtimes for Intel® CPU (x86-64).
  • For application developers, the CPU-only runtime is pre-included with the Intel® SDK for OpenCL™ Applications or Intel® System Studio: OpenCL™ Tools component.

Check release notes to ensure supported targets include your target device. For Intel® processors older than supported targets, see the legacy deployment page.

Intel® CPU Runtime for OpenCL™ Applications 18.1 for Linux* OS (64bit only)

Download

  • Size 125 MB
  • See supported platform details in the Release Notes.
  • Ubuntu* install uses an rpm translator
  • The Linux* OS CPU runtime package also includes the ICD loader runtime (libOpenCL.so). The runtime installer should set the deployment system to see this ICD loader runtime by default. When examining system libraries, administrators may observe ICD loader runtimes obtained from other places. Examples include the system package manager (for example with ocl-icd) or as part of the Intel® SDK for OpenCL™ Applications.
  • Maintenance and updates are now provided in the Experimental Intel® CPU Runtime for OpenCL™ Applications with SYCL support implementation. This implementation is listed later in this article.
  • MD5 83c428ab9627268fc61f4d8219a0d670
  • SHA1 5f2fa6e6bc400ca04219679f89ec289f17e94e5d

Intel® CPU Runtime for OpenCL™ Applications 18.1 for Windows* OS (64bit or 32bit)

Download

  • Size 60 MB
  • CPU-only deployments should use the .msi installer linked in the Download button, and consider removal of the Intel® Graphics Technology drivers where applicable.
  • CPU & Graphics deployments should use the Intel® Graphics Technology driver package, which contains both CPU (x86-64) and Intel® Graphics Technology implementations.
  • See supported operating system details in the Release Notes
  • Maintenance and updates are now provided in the Experimental Intel® CPU Runtime for OpenCL™ Applications with SYCL support implementation. This implementation is listed later in this article.

Experimental Intel® CPU Runtime for OpenCL™ Applications with SYCL support

Download from Intel staging area for llvm.org contribution: prerequisites.

Installation Guide on Github*

  • This OpenCL™ implementation for Intel® CPUs is actively maintained. It is currently in *beta* as of article publication date.
    • OpenCL 1.2, 2.0, and 2.1 programs can use this runtime.
    • The DPC++/SYCL implementation can use this runtime. This runtime additionally supports the SYCL runtime stack. OpenCL™ developers are highly encouraged to explore Intel® DPC++ compiler and SYCL.
  • Deployments with the Intel® CPU Runtime for OpenCL™ Applications 18.1 and this Experimental runtime are not jointly validated at article publication time. Use one or the other implementation, but not both.
  • Feedback can be provided at the Intel® oneAPI Data Parallel C++ forum. Issues are also communicated at the Intel staging area for llvm.org contribution.
