Is there a way to disable this feature (ie, make the PC crunch regardless of the CPU usage by other apps) thru online-settings? Or do I have to disable this manually on each PC individually?

Thanks.

Are you using the default settings of 100% usage at all times?

Here are my settings:

Processor usage
Use at most
Enforced by version 5.6+ 100 percent of CPU time

and in Boinc Manager:

Advanced menu option > Preferences Use at most 100% CPU time.

These settings if I understand correctly make BOINC the highest priority on the system.

you could use an account manager (e.g. BAM) but you'll have to set that up on all machines first...

If you are using one of the later versions of BOINC, they added a new "feature" to help you ... if the CPU use on the machine for any reason goes over 30% BOINC goes to sleep... most of the projects have yet to update the server side software to accommodate this new setting, at least Rosetta has not as yet, so you either have to set it on a project that allows this (SaH, Collatz are two I know allow it)... or set it locally ...

Those of us that advised that the setting is too low got blown off by UCB (as usual) and I had it triggered multiple times one night even though I was in bed and I have no automated activities running on the machine ...

So, if you attach to SaH, set NNT, make the setting change there, abort any tasks issued you can still make the setting using the remote ...

Ah, so this is a new BOINC feature. I only upgrade BOINC in two of my computers that I use most (laptop and desktop), I guess the rest don't have that feature yet, because they are just there heating the house :P

Yep, new feature ... and almost everyone that notices it regards it as a bad thing.

Personally I think it is another solution in search of a problem. The only time BOINC has ever gotten in my way is from GPU usage and this feature is not likely to make a dent in that because of the way GPU tasks run ... if you have lag, you will still have it because the GPU Kernel does not shut down right away even if the parent task dies ... one of the reasons I did not run AP26 tasks on the mac was that the tasks were badly made and I got too much lag on the system... I run Collatz on the Mac all day long and never notice it at all (though the Mac card is slower than dirt ...)

Anyway, as more projects update the server side you will be able to make the setting change there...

I notice significant graphics lag while running collatz (ATI Card only). So I set it to run after 1 min of inactivity. The lag shows whether I OC the card or not. Windows 7.

If you run the anon platform you can "tune" most of the versions of Collatz so that this effect is minimal. For me, on all my systems running ATI cards I have not noticed this issue to any extent... but, as always, YMMV ... :)
