Here's the FAQ: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=20741 the 2) is the simplest set-up

Thank you, I was thinking about this this morning actually.

I know this is difficult, but is there a way of making WCG run on 50% cores during work hours and 100% of cores outside of work hours?

Thank you Lawrence.
Is that easy to do? I have no programming skills to be honest.
If it can be done, it can potentially gain another 9-10 days of computing a week

Well, a basic script would be along these lines, if you've made two different global_prefs_override.xml-files called cpu_50.xml and cpu_100.xml

:start
copy cpu_50.xml global_prefs_override.xml
call "c:\program files\boinc\boinccmd" --read_global_prefs_override
sleep 28800
copy cpu_100.xml global_prefs_override.xml
call "c:\program files\boinc\boinccmd" --read_global_prefs_override
sleep 57600
goto start

I've assumed the script is run from the BOINC data-directory and BOINC-client is using the default program-directory (c:\program files\boinc). Assumed is run manually in the morning for so continuing to run. Also, has assumed 8 hours work-hours and 16-hours off-work-hours.
The only requirement in this script is you'll need a sleep-application, downloading sleep.exe from internet is easily done.

Another possibility is to use two scripts, and set up two different sceduled tasks. If so, use

copy cpu_50.xml global_prefs_override.xml
call "c:\program files\boinc\boinccmd" --read_global_prefs_override

in one script and

copy cpu_100.xml global_prefs_override.xml
call "c:\program files\boinc\boinccmd" --read_global_prefs_override

in another script.
