I think you'll find that BOINC is designed to be a screensaver under
Windows because that's about the only way it can get as much CPU time as
it needs without interfering with your other work.

The native Linux version does a rather better job: it runs 24/7 as a
'niced' background task and so can sop up every bit of unused CPU that
is available without having any detectable effect of your own work. It
can even run more than one project simultaneously without interfering
with what you are doing. I ran SETI at home and MalariaControl together on
a fairly small box (866MHz P3, 512MB RAM) without any problems: every
few weeks I'd peek to see if it was still running: it always was.

However, there is one caveat: if you're doing it just to use up idle
cycles its fine on an older box with fixed CPU speeds because the power
consumption and CPU speeds don't change with the system workload.
However, on a modern variable speed box BOINC will spin the CPUs up to
max speed and burn through a lot of power that you wouldn't be paying
for if you weren't running it. I recently replaced the P3 with a dual
core Athlon system which was well-behaved and ramped up and down nicely
during Linux install and configuration. That is, until I fired up BOINC.
That's when all fans spun up to max speed and the machine sat there
howling and blasting hot air out its vents. I stood the noise for a day
and then dumped BOINC.
