OpenCL and Compatibility Pack

Altamir Gomes 0

Hi. I installed the OpenGL and OpenCL compatibility pack from Microsoft, but anything OpenCL I throw at my Windows ARM laptop with Adreno 618 GPU fails to retrieve a result. I tried another box with a Intel HD Graphics 630 GPU, but to no avail. The native OpenCL driver of the Intel box, from Intel itself, works fine.

Does OpenCL have proper support from the Compatibility Pack on Windows 10/11? What's your personal experience with OpenCL apps and support from the Compatibility Pack?

Just for the record, I ran a sample DirectX 12 Compute Shader program on the same machine, and it did retrieve a result allright. I simply do not understand why OpenCL on DirectX 12 refuses to work.

I built and ran openclon12test.exe from OpenCLOn12 (https://github.com/microsoft/OpenCLOn12), output follows: [==========] Running 9 tests from 1 test suite.

Hello there,

This is the article published by Microsoft.

The OpenCL and OpenGL Compatibility Pack includes an OpenGL ICD implementation and an OpenCL compiler stack from the Mesa project, as well as an OpenCL ICD implementation from our own open source repository. The OpenCL compiler stack leverages even more open source components: It uses Clang/LLVM 10.0, the SPIRV-LLVM-Translator project, and the SPIRV-Tools project before converting OpenCL SPIR-V into Mesa’s NIR format and finally to D3D’s DXIL format.

However, why it does not work on OpenCL compute workloads? Must the card sport full support to DX12, as the Feature Level of the Adreno GPU is only up to DX 11.1?
