OS: Ubuntu 24.10

Linux Kernel: tested on both 6.11.0-generic and 6.12.0-rc3

CPU: intel ultra7 258v

GPU: 64a0

 

How should I run OpenCL applications using this GPU on Linux?

 

Compile models using OpenVINO:

RuntimeError: Exception from src/inference/src/cpp/core.cpp:104:
Exception from src/inference/src/dev/plugin.cpp:53:
Check 'false' failed at src/plugins/intel_gpu/src/plugin/program_builder.cpp:185:

Exception from src/plugins/intel_gpu/src/runtime/ocl/ocl_stream.cpp:384:
