Comment Re:CPU Throttling (Score 1) 136
It depends on your CPU scheduler and your throttling algorithm, too.
I run BOINC on linux. BOINC is "niced" to have an idle priority, meaning that CPU time is only granted to it if there's nothing better to be doing. In addition, I used the on-demand frequency governor which I have instructed to ignore "niced" processes when determining whether to spin up the CPU.
As a result, yes, BOINC only uses spare CPU cycles and not too many of them, either.
