A long time ago I asked for the ability to control how many cpus are used for boinc. I see that this has not been accomplished; therefore I'll be STOPPING ALL BOINC activity on my computer.

I guess you either want all my cpus running or none. Here have none...

It's ridiculous that I needed to create an account just to say bye.

I take it you've never been in your General Preferences on any project?

Processor usage
Do work while computer is running on batteries?
(matters only for portable computers) no
Do work while computer is in use? yes
Do work only between the hours of (no restriction)
Leave applications in memory while suspended?
(suspended applications will consume swap space if 'yes') yes
Switch between applications every
(recommended: 60 minutes) 60 minutes
On multiprocessors, use at most 1 processors
Use at most 100 percent of CPU time

See that bold line? You change the amount of CPUs you want BOINC to use there.
Then you Update BOINC on that project, so it knows you changed the setting.

It is that easy. And it's been in BOINC since version 4.20, if I am not mistaken. Maybe even before. Since we're now at Boinc 5.8.11, a long time.

OK, I WAS running 4 projects. Set each one to use one processor and boinc will fill two processors, right? There is nothing to throttle boinc (and all charity clients) to one processor.

...yer it!

It's in the General preference. You can set it at any project and Boinc will only use the number of CPU you indicate. As with any setting change Boinc doesn't get updated until it contacts the project where the change has been made.

Which project/WU will get the CPU is determined by your resource share and Short term debt. Boinc recalculated the debt and checks if any WU in in deadline trouble at the switch time set in the preferences, when a WU in completed and when new work is downloaded. It then decides whether to continue with the same WU or switch to another WU in your queue.

If you use two or more CPU you could have any combination of projects/WU running simultaneously, again, based on resource share and STD.

edit: If you use Boinc version 5.8.x you can use the preferences setting in the Simple GUI to locally override some of the settings at the projects websites. The number of CPU used by Boinc can be controlled locally.

Is there a university course I can take on how manage Boinc?

I just uninstalled and deleted the Boinc directory. I got 9GB back. You try to help folks out and they take advantage every time...

It's not needed. For most people it is set it and forget it. There are FAQs and a full Wiki (see my signature) for folks that want to know more. Plus lot of volunteers to answer any question for those that don't have the patience to look things up.
