To build an x86 host side application with the OpenCL API, strictly speaking an OpenCL implementation is not needed.we can use it to see if the ocl runtimes are setup as intended: For an opencl platform interrogator tool, many users try clinfo available off github precompiled for windows.

The drivers tab should have a version string.
#AMD OPENCL DRIVER WINDOWS 10 UPDATE#
Intel System Studio 2019 Update 4: OpenCL Tools is debuting now. Intel System Studio 2019 Update 3: OpenCL Tools is incompatible with the DCH drivers per release notes. A vendors versioning scheme may make it difficult to determine if it's a DCH driver in particular or not. Vendor graphics drivers should be preferred in deference to vendor support agreements related to driver usage. They also may have their own versioning schemes. Vendors tend to trail Intel graphics driver releases.
Typically, users go to a system vendor for the graphics driver. Intel started providing DCH drivers around the turn of the year. Detail:ĭCH drivers are a new driver type for the Windows* 10 operating system.
What is really meant is a first party Intel product. Remark 2: on a system with NVIDIA GPU (with GeForce 417.35) + Intel GPU (driver v6444), these tweaks are useless too, because Intel OpenCL support is properly enabled.The clinfo feedback suggests the runtimes are in place to execute OpenCL applications. Remark 1: on a system with no AMD GPU, these tweaks are useless, because Intel OpenCL support is properly enabled after Intel driver installation. Once these values have been created, the OpenCL support for Intel CPU and GPU finally appeared: In the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenCL\Vendors key, create a DWORD value with the following name:Ĭ:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_f02a6686365638a8\IntelOpenC元2.dll I found this path in the registry (look for IntelOpenCL_圆4_CpuRuntime or IntelOpenCL_x32_CpuRuntime values): In the HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors key, create a DWORD value with the following name:Ĭ:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_f02a6686365638a8\IntelOpenCL64.dll These values properly enabled OpenCL for Intel CPU/GPU on my test system when AMD Adrenalin 18.12.3 driver was already installed. On my test system, the first key was not present and the second key was present but with a value that didn’t work… This key lists all OpenCL implementations (see the cl_khr_icd OpenCL extension for more details). For 32-bit apps on Windows 64-bit, the key is: KEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenCL\Vendors. The OpenCL ICD (Installable Client Driver, the OpenCL.dll shipped with the graphics driver) tries to load all OpenCL implementations described in the HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors key (64-bit app on Win64 or 32-bit app on WIn32) of the registry. Here is the tweak to enable OpenCL support for Intel processors. Let’s see the same support with a 64-bit app like the prototype of the upcoming GPU Shark 2: – CPU: Intel Core i7-8700K + UHD Graphics 630 + Intel v6444 driver But here is a way to enable the Intel OpenCL support on Windows 32-bit and 64-bit with a simple registry tweak.īefore tweaking the registry, here is the OpenCL support on my test system: Probably a savory story of drivers (AMD?). So why is Intel OpenCL support disabled when an AMD Radeon GPU is present? Sorry, I don’t have the answer. If you search for Intel OpenCL related files with Explorer or Regedit, you will quickly find that all OpenCL driver files are there.

On a Windows 10 system with an AMD Radeon GPU and an Intel GPU (desktop or notebook), with graphics drivers installed for both GPUs, I bet you will see that OpenCL is limited to the AMD GPU only.
