Mac OS X Snow Leopard (version 10.6) is the seventh major release of Mac OS X (now named macOS), Apple's desktop and server operating system for Macintosh computers. Snow Leopard was publicly unveiled on June 8, 2009 at Apple’s Worldwide Developers Conference.On August 28, 2009, it was released worldwide, and was made available for purchase from Apple's website and retail stores at the.

  1. The OpenCL platform has returned to OS X! As of Mac OS X 10.10.3, Apple has finally fixed the last of their critical OpenCL bugs, so we are able to make that platform available again (but only enabled on 10.10.3 or later). Doesn't sounds like an Apple issue anymore. Priority might be low to implement due to number of potential users with actual.
  2. OpenCL On OS X Basics. Tools provided on OS X let you include OpenCL kernels as resources in Xcode projects, compile them along with the rest of your application, invoke kernels by passing them parameters just as if they were typical functions, and use Grand Central Dispatch (GCD) as the queuing API for executing OpenCL commands and kernels on the CPU and GPU.
  3. The broad industry support Apple is building around OpenCL will help increase the critical mass behind OpenGL, the 2D and 3D graphics language Apple uses extensively in Mac OS X. By Prince McLean.

Deploy OpenCL™ Runtimes

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

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.
    • Github: https://github.com/intel/llvm/releases
      • Search for 'oneAPI DPC++ Compiler dependencies' and find latest release to download, e.g. https://github.com/intel/llvm/releases/tag/2020-WW20
      • Following the installation instructions to install

Opencl For Mac Os X 10.8

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

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.

Opencl

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.

A course I’m currently taking required me to optimize some C++ code usingOpenCL, a framework for writing parallelized programs that run across“heterogeneous systems” - be it your CPU, GPU, and other types of processingunits.

The skeleton code supplied to me was configured to work with Linux C++ bindingsand run on the school’s environment where these bindings were alreadyconfigured - I’d have to ssh into the environment and execute the coderemotely. To actually complete my assignment I’d either have to develop locallyand copy my code over whenever I wished to test it, or develop remotely. Whilethis was a doable solution, I preferred to write and run the code on my Macbook(running OS X High Sierra) and not have to rely on another environment to testsimple changes.

Getting OpenCL to work with C++ bindings took a bit of scouring the web. Mostof the tutorials and how-to posts targeted and explained setup of C bindings,and not C++, so I figured I’d share a simple how-to for anyone else who mightrun into this issue.

Opencl For Mac Os X64

Setup

Mac OS X should already come with the OpenCL framework installed. You canconfirm this by checking for it’s existence:

Disable SIP

We’re going to need to download the appropriate headers to the Headersdirectory of the framework. If you’re running a version of OS X Yosemite orlower, you can skip to the next section. However, if you’re running El Capitanor higher, you’ll notice that attempting to copy anything into this directorywill be restricted, even with root access. This is due to SystemIntegrity Protection (SIP), a new security feature. Thanks, Apple ಠ_ಠ.

To disable this, you’ll need to boot into Recovery Mode. Do this by restartingyour computer while holding down Command(⌘)+R during the boot phase. Once inRecovery Mode, select Utilities > Terminal and disable SIP using:

You’ll need to reboot your machine again for the changes to take effect.

(To re-enable SIP after installing, you can repeat the process using csrutilenable instead of disable. Restart to apply changes.)

Install Headers

Now that SIP is disabled, you can download the OpenCL .hpp header file to theOpenCL framework headers. Head over to the Khronos OpenCLRegistry page and download the cl.hpp header. Then, copy the header tothe directory Headers directory. You’ll need root access to modify thisfolder.

That’s it! The bindings are added and ready to use.

Usage

Opencl For Mac Os X 10.13

Mac

Opencl For Mac Os X 10.10

While the Linux bindings are included using #include <CL/cl.hpp>, the Mac OSbindings require you to use:

If you want your code to work on both platforms, simply add an #ifdef__APPLE__ or the likes and take advantage of predefined compiler macros to#include the right header for the platform.

Make sure to link OpenCL when compiling your code. With g++, the argument is:

Summary

(Step 1 needed for OS X El Capitan and above)

  1. Disable SIP (Boot into Recovery Mode, csrutil disable in Terminal, andreboot)
  2. Download the cl.hpp header from the KhronosOpenCL registry
  3. Copy the header to /System/Library/Frameworks/OpenCL.framework/Headers
  4. Use the bindings (#include <OpenCL/cl.hpp>) in your source code
  5. Compile your code with the -framework OpenCL argument (on g++ at least)

Thanks for taking the time to check this post out. Hope it saves you some timeand trouble with your OpenCL setup.
Happy kerneling!
