"opencl_nvidia_101" WU's do not use my nvidia unit. How can I insist on CUDA WU's ?

All I found was this website on the topic.

What nvidia unit do you have? Does BOINC 'see' the nvidia unit upon boot (see BOINC-log)?

I see you have both a Intel UHD 620 GPU and a NVIDIA GeForce MX150, does BOINC see both?

The following assumes your BOINC data directory is C:\ProgramData\BOINC.

Step by step:
1. Start up Notepad
2. Paste the following code into your cc_config.xml file, located in C:\ProgramData\BOINC. If it doesn't exist, make one using notepad, save as .txt and alter the suffix to .xml (ignore the warnings).
<cc_config>
    <options>
        <use_all_gpus>1</use_all_gpus>
    </options>
</cc_config>

3. Save it into C:\ProgramData\BOINC as cc_config.xml (careful, Notepad likes to put .txt on the end of the filename)
4. Shut down your BOINC client if its running
5. Start BOINC up again

You should have a couple of messages in the startup about config: and it should use both GPUs
Are you using the standard driver, or the one downloaded from nVidia? For full CUDA performance use the last nVidia-supplied driver for your card.

Would be nice if they updated the CUDA app to use newer versions of CUDA too. Would be much faster and use the GPU fully.
