Yes, if it's lower, it will stop BOINC earlier. That's wrong. At least for most participants and for the "Use of unused CPU-cycles".

You're still thinking about yourself and the people who leave BOINC running 24/7/365. Instead think about the people who do have BOINC running while they're active on the computer, but who find their system to slow down when they open anything else, as the science app isn't giving up its cycles quickly enough.

It's even for those people who only let BOINC run when their computer is otherwise idle and something outside BOINC needs more CPU cycles, like a scheduled AV scan. You wouldn't want BOINC to be active while a scan is happening anyway.

The 25% is for 1 core, only when another program outside of BOINC uses that many CPU cycles (check Windows Task Manager). It'll suspend the whole of BOINC since it's BOINC that is taking up all left-over CPU cycles at that time, when you do not want that.

It's not a preference to pester you who run 24/7 BOINC only, it's a preference to help those who find their system is slowed down when they do other things with their system. Take off the blinders, check out your surroundings, there's other people out there who use their systems differently than you are. :-)

I still don't know what will happen on a normal PC, i.e. one with 2-8 cores.
Will it stop completely if only one core is used for more than 25% or will only that core be taken from BOINC?

Is the 25% that what normal people will think, 25% of the overall power of the machine, or just 25% of one ( sometimes quite tiny) part of it?

Aah, and I would have to look in the gnome system monitor, there's no use for the windows task manager on my machine ;)

It's 25% of the total power of the machine. If you have four cores, that would be the equivalent of 1 core full time, and nothing at all on the other cores - except no self-respecting operating system would ever run the hardware that way. It's far more likely to be 25% of each of however many cores you have, +/- 25% in every case.

And please do check that you're looking at this from the right end of the telescope. BOINC excuses itself and gets out of the way if other tasks are using 25% of the CPU(s). Or more. So 26%, 27%, 30%, 50%...... stop BOINC. Conversely, if other tasks use less than 25%, BOINC runs ... at 24%, 23%, 20%, 10%, 5%.

Don't be confused, easy though it is, that the figure '0' (note: not a percentage) is used to represent 100%, to save typing.

Check BOINC's message history for other red text. If you are low on disk space you can encounter your problem. Also make sure your settings allow enough disk space for it to use.

Go into Preferences in your BOINC Manager, press the Clear button, then exit. Go to the SETI@home web site and set your Computing Preferences there, then go to the BAM! web site and do the same. Now go into your BOINC client and synchronize your client.
