Hmm... perhaps I've had a brain fade here but I can't seem to get M/T to work?

Resource share set to 0
CPU selected.
Multi-threading: Max # of threads for each task - 8 (This number isn't important... I'm just trying to get M/T to work at the moment so this would be 2 tasks across 16 cores)
I've selected MEGA - CPU
Confirmed that this pc is using the default setting (not home, work etc)
CPU usage set to 50% in BOINC manager to use cores only.

I've even tried closing BOINC and re opening but it still runs 16 task.
What have I missed here??

Tried this on another pc and get the same result.

The only thing I can think of is I have BOINC set to hold 7 days work in the cache? Is that it?
*Please note... I know to leave the cache set to zero normally.... I was initially just testing run times for MEGA using different amount of cores (which I've done in the past) but can't get to work now.
I'm sure it must be something trivial.

TIA

GFN 17-Mega does not have a MT app.
Look on Primegrid main page and see the apps that show MT.

Do you mean PPS-MEGA? Multihreading settings are only applied to new tasks. Existing WUs won't be updated with the new thread count. So, either abort them all or let them finish, and new tasks will start with 8 threads.

Ah HA!!!!
I KNEW it would be something silly!!! Oops. Thank you all.

Yes... I accidentally tested GFN-17 MEGA.

Thank you Pooh Bear... I'd never noticed on the home page about MT tasks being mentioned.

Problem solved (as I shuffle off embarrassed) lol.
