there. I don't even know if this question makes sense, however: how do BOINC-based applications adapt their performance so that they only use "free" CPU, without affecting the execution of user's applications?
Thank you,

They set their process priority to the same as the idle thread?
In windows SetPriorityClass() about IDLE_PRIORITY_CLASS:
Process whose threads run only when the system is idle. The threads of the process are preempted by the threads of any process running in a higher priority class. An example is a screen saver. The idle-priority class is inherited by child processes.

Most likely they just set the priority of their computation thread(s) to something very low, and then rely on the OS's scheduler to do the rest. Threads/processes with a low priority will only run when no other threads need the CPU time for anything.
