I have set 'Use at most 50 percent of CPU time' on the Profile web page for BOINC, but the program uses 95-100% of the CPU. Why? How can I fix it?

Problem: Setting CPU usage

Wait for the next BOINC version to be released. That setting does not work on BOINC 5.2.x and 5.4.x

It's an option for 5.6.x (and works in the alpha tests 5.5.x).

i have kind of that problem

i have kind of that problem just a bit different:
my project process uses 50% everytime, idle process ~40% and other programs the rest.
but i dont wanna have so much unused cpu power. i activated a default config on my conputer at boinc (simple display -> preferences -> my own config) and set max cpu usage to 100%, working everytime while computer is in use, too. but the process usage never get over 50%, its frozen there.
some tips for me?

(sorry for my english, im german ^^)

You have a Hyperthreaded machine, so each process runs at 1/2 the processor. Quads show 1/4, etc. It all adds to 100%. So two instances at 50% should be running. Check the setting "Use at most ? processors" and make sure it is 2.

When you use the simple GUI's preferences, it will make a global_prefs_override.xml file that doesn't have the entry 2 .. But according to the developers, if it's not in the override file, BOINC will fall back to the global_prefs.xml file for the rest of the settings.

So the global_prefs.xml file should have an entry for your max CPUs used.
Else set them again through your preferences and update BOINC through Boinc Manager, Projects, Select Einstein, Update.
