Admin, could you please check again whether after you have completely exited from BOINC you still see high CPU activity, which probably means that the task(s) are still running.

Do not upgrade or reinstall BOINC until all CPDN models have finished. Then reset or detach from CPDN and do the upgrade.

What a nuisance. I've looked at what I think is the same Mac Mini on Rosetta and SETI and noticed some interesting things. But I can't post what I wrote because the Akismet anti-spam program for this forum is blocking my post. Of course there is no spam in my post.

Same problem with me.

4. In the Mac Mini BOINC Manager Projects tab, which projects are listed?

5. In the Mac Mini BOINC Manager Tasks tab, how many tasks are listed and which projects are they from?

how many tasks?

which projects are they from?

6. When did you update to a new BOINC version on the Mac Mini that's processing CPDN?

Hello again

Could you please tell us:

1. When you posted here on the SETI forum 4 years ago could you confirm that you were discussing a different Mac computer? I think the specs of that machine look completely different but I want to be sure.

3. How many Mac Minis with BOINC installed have you got?

Your model may well be encountering a different problem, but the information needed is in the Show graphics window.

If you select (click on), the model name, does the show graphics button become active, or does it remain greyed out?
If it's active, then there's a problem with one or more of the files on your computer needed to display the OpenCL graphics.

Neither BOINC 6.12 version nor current 7.0.31 do not show graphics of any project. The MAc minis have no HDD LEDs.

I have set somethig like Run BOINC Always in my Prefs, and it runs always as my CPU activity utility shows

That "always" is only while YOU aren't typing or running something else. i.e. BOINC only runs in the gaps between pressing a key.

There's a countdown timer which is visible in the Show graphics display. When it reaches zero, the disk activity light should flash for a while as data is saved.

(In the Tasks tab, click on the model name, then click the Show graphics button.)

If the scenario I'm imagining is true, I think you'd have to set all your projects to No New Tasks in the Projects tab and see whether this model can then progress as it should.

I don't know very much about Mac Minis but I also wonder whether their cooling system is powerful enough to crunch BOINC on two or even one core if the CPU is being used at 100%. I wonder whether the machine is throttling ie limiting CPU usage to keep the CPU cool. If this is the case would it be necessary to limit CPU usage in account preferences?

...Are you crunching tasks from another BOINC project simultaneously on the other core? I think this would be too much for the machine and if this is what's happening it may explain why the model's never reaching the end of its first model year.

...but are you just closing the BOINC Manager window? Or are you exiting from the whole BOINC process?

I first suspend the models using the Activity menu. You can then exit from BOINC in either of two ways:

In BOINC Manager > File > Exit

The tasks from a lot of projects don't seem to mind the computer being shut down while BOINC is still processing but climate models don't like this at all.

However, BOINC only runs it's work when you aren't using the computer, and you if use it heavily then the projects won't get much time for their work. And, as you appear to be running several projects, the work from each will have to share what time is being allowed.
