GPUPluginDriverTroubleshooting
If you see errors like "[CLDNN ERROR]. clGetPlatformIDs error -1001" when running OpenVINO samples / demos, then most likely you have some issues with OpenCL runtime on your machine. This document contains several hints on what to check and how to troubleshoot such kind of issues.
In order to make sure that OpenCL runtime is functional on your machine, you can use clinfo tool. On many linux distributives it can be installed via package manager. If it's not available for your system, it can be easily built from sources.
Example of clinfo output:
Number of platforms 1
Platform Name Intel(R) OpenCL HD Graphics
Platform Vendor Intel(R) Corporation
...
Platform Name Intel(R) OpenCL HD Graphics
Number of devices 1
Device Name Intel(R) Graphics [0x3e92]
Device Vendor Intel(R) Corporation
Device Vendor ID 0x8086
Device Version OpenCL 3.0 NEO
Driver Version 20.49.0
Device OpenCL C Version OpenCL C 3.0
Device Type GPU
Some Intel® CPUs might not have integrated GPU, so if you want to run OpenVINO on iGPU, go to https://ark.intel.com/ and make sure that your CPU has it
On Windows OpenCL runtime is a part of the GPU driver, but on linux it should be installed separately. For the installation tips please refer to OpenVINO docs and OpenCL Compute Runtime docs. To get support of Intel® Iris® Xe MAX Graphics with Linux* please follow driver installation guide
Add the current Linux user to the video
group:
sudo usermod -a -G video "$(whoami)"

Openvino contains hello_query_device sample application: link
With this option, you can check whether Intel XMX(Xe Matrix Extension) feature is properly recognized or not. This is a hardware feature to accelerate matrix operations and available on some discrete GPUs.
