It's too bad... I have a Intel 11th-Gen PC and it has a little powerful Xe GPU, but.... for NumberFields, it seems not be good enough:

<core_client_version>7.20.5</core_client_version>

Updated:

I downgraded (rollbacked) to an earlier release of Intel's NEO compute runtime, and then the OpenCL seems to work normally
