Deploy OpenCL™ Runtimes

  • Unfortunately both Cuda and OpenCL aren't enabled. I've tried the following driver versions: - 372.70 (from Asus website) - 368.81 (from Asus website) - 378.78 (from Nvidia) - 376.33 (from Nvidia) - 372.90 (from Nvidia) All but 378.78 let programms like CPU-Z and Houdini tell that there is no CUDA/OpenCL card present.
  • Intel SDK for OpenCL Applications is a development kit designed to help advanced computer users such as software developers or programmers build and run OpenCL applications on Intel platforms.

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

  • Intel® Graphics Technology Runtimes
    • Target Intel® GEN Compute Architectures on Intel® Processors only
  • Intel® Xeon® Processor or Intel® Core™ Processor Runtimes
    • Target Intel® x86/x86-64 only

If a DirectX 12 driver is installed, supported apps will run with hardware acceleration for better performance. This package supports apps that use OpenCL version 1.2 and earlier and OpenGL version 3.3 and earlier. Only certain apps can use this compatibility pack. The OpenCL CPU runtime is removed from the OpenCL driver for Windows starting in the 2020 February release version 'igfxwin10100.7870.exe'. But the installer of the new driver did not remove the old OpenCL CPU runtime when you upgrade the newer driver, so you may have two OpenCL CPU runtimes on your system. OpenGL drivers are always Pre-installed in your windows system but for some reason, the drivers are missing or they have not been updated properly then you can experience some slow performance in the new graphic card module and that’s the reason you require to update OpenGL drivers.

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'.

  • But the installer of the new driver did not remove the old OpenCL CPU runtime when you upgrade the newer driver, so you may have two OpenCL CPU runtimes on your system. This issue is already fixed in the installation script on github here.
  • To download the OpenCL CPU runtime for Windows, please follow any of the following methods:
    • Follow the section 'Intel® CPU Runtime for OpenCL™ Applications 18.1 for Windows* OS (64bit or 32bit)' below to download and install.

      • Following the installation instructions to install

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.

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

Note: The latest OpenCL runtime for CPU requires GNU* gcc version 7.3 or newer.

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:
    • Your system package manager (for example with the unofficial ocl-icd )
      • Useful package manager search hints:
        • apt update; apt-file find libOpenCL.so
        • yum provides '*/libOpenCL.so'
    • Build from the official Khronos ICD Loader reference repository.
    • Part of the Intel® SDK for OpenCL™ Applications.
  • 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.
    • 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.

First versions of OpenCL implementations are now available for NVIDIA and AMD platforms (platform… this is a term you will see often with OpenCL). Here is a small HowTo about enabling OpenCL on Both AMD and NVIDIA hardware under Windows.

Enabling OpenCL on NVIDIA platform

On NVIDIA platform, OpenCL comes with the latest R195.39 or R195.62 WHQL. R195.39 is the first driver that offer a public OpenCL support. The OpenCL.dll that comes with R195.38 is actually the Khronos OpenCL interface and real OpenCL implementation is hidden in some nvcuda files… Anyway installing R195.39 / R 195.62 is enough to have OpenCL on your system. After the driver installation, start GPU Caps Viewer 1.8.0 and you should see something like this:


All GeForce 8 and higher are OpenCL-capable devices.

Enabling OpenCL on AMD platform

Ah here we are, with AMD it’s trickiest! The most important thing is that your system must be clean of NVIDIA display driver residues. If, like me, you have both ATI and NVIDIA drivers on your system, the GPU code path of AMD’s OpenCL won’t work. Only the CPU code path will be ok. Yes, my friends, AMD provides OpenCL with CPU and GPU support. Really cool. To be sure your system is clean, just run Guru3D’s driver sweeper to remove ForceWare leftovers.

Opencl Driver

In some cases, it’s not enough and a fresh install of Windows may be the solution (that’s what I did for Catalyst 9.12… 🙁

Opencl Driver Nvidia

Now you have a clean system, you have to install the latest Catalyst 9.12 hotfix that includes OpenCL support. Actually, Cat 9.12 doesn’t inlcude a standalone OpenCL support: you must install the ATI Stream v2 beta4.

Once the Catalyst 9.12 is installed, you have to install the ATI Stream beta4 SDK. After that, you should have an OpenCL GPU + CPU support. Want to be sure? Start GPU Caps Viewer 1.8.0 and you should see something like this:

From my tests, on Windows Vista, OpenCL GPU is supported by Radeon HD 3000 (at least the HD 3000 is detected as an OpenCL device but I didn’t manage to run the demo because of a linking error), Radeon HD 4000 (I tested a HD 4850 with success) and HD 5000 series (HD 5770 and HD 5870).
