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>

How many gfx memory does OpenCL need for GPU? especially for Intel's integrated gfx core...

CPU type	GenuineIntel
11th Gen Intel(R) Core(TM) i3-1115GRE @ 3.00GHz [Family 6 Model 140 Stepping 1]
Number of processors	4
Coprocessors	INTEL Intel(R) UHD Graphics [0x9a78
[6002MB] 1 () driver: 3.00

Need some gfx configuation tuning?!

Updated:

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

Good to hear you got it working!
