In Jiefei-Wang/gpuMagic: An openCL compiler with the capacity to compile R functions and run the code on GPU

The package requires an ICD loader and a opencl-enabled CPU/GPU driver. This installation guide will show you how to install the dependecies step-by-step.

Windows

For windows users, the easiest way to check if you have an ICD loader installed is to search for the file OpenCL.dll under C:\Windows\System32\ directory. If the file does exist and gpuMagic package can find your devices through getDeviceList, you can safely skip this instruction. Otherwise, please follow the instructions below to install/reinstall graphic drivers. Usually the ICD loader will be installed by a driver, there is no need to install an ICD loader.

Find the name of GPU(s)

1.Press win+R shortcut

2.type CMD and press OK button

3.type wmic path win32_VideoController get name in the popped up black window, then you can see the name and vendor of your GPU(s).

Install the driver

According to your GPU vendor:

For intel:

https://downloadcenter.intel.com/product/80939/Graphics-Drivers

For Nvidia:

https://www.nvidia.com/Download/index.aspx?lang=en-us

For AMD/ATI:

If vendors offer a selection between developer and gamer drivers(at leaset Nvidia does it), please choose the developer one.

Reboot and check the ICD loader again

After the installation, reboot your system and check the file OpenCL.dll again, if it still does not exist, please contact the vendor through its support website to locate the OpenCL.dll. It may be necessary to manually move this file to fix this issue. The ICD loader can also be compiled from the source code, please see https://github.com/KhronosGroup/OpenCL-ICD-Loader for reference.

Linux

Install the driver

Like on windows, please go to the vendor's support site to find the correct driver and install it.

Install Installable Client Driver(ICD)

Please run the following command to install ICD:

sudo apt update

sudo apt install ocl-icd-opencl-dev

Check if the device is available

You can use the command-line tool clinfo to check the device availability.

To install clinfo, run

sudo apt-get install clinfo

If you can see your devices, the drivers are installed and you should be able to use the package. If you cannot see any device, you may need to reinstall the driver and see if it works.

MAC

There is no special requirement for MAC, the package can be installed normally.
