Sekerob,

This link explains everything!

Thank you very much!

(I'll post my solution here as soon as I tested it...)

Run on Batteries only works when... there is no 220v. In past that worked for me both on laptop and on the Desktop that's attached to a UPS... that the OS recognizes as now I've got cheepo's that just run much longer than the expensive one with bells and whistles (Trust).

Did you try reading in the file via the menu? You should see message log entries similar to the below

02/12/2009 08:19:24 World Community Grid Computer location: work
02/12/2009 08:19:24 General prefs: using separate prefs for work
02/12/2009 08:19:24 Reading preferences override file
02/12/2009 08:19:24 Preferences limit memory usage when active to 1534.63MB
02/12/2009 08:19:24 Preferences limit memory usage when idle to 1841.56MB
02/12/2009 08:19:24 Preferences limit disk usage to 10.00GB

If I enter a 50% value directly the prefs, the client immediately responds upon save by producing these log entries

Oh, and Run according Preferences must be set in the Activity Menu.

The LIM/LAIM setting is important. Frankly I've not tested if Preempting, leave in memory is automatically activated when running the BOINC throttle. It should, spock logically, else there would be no progress during throttling.

Well, the editor to use is Notepad as wordpad sometimes drops in invisible characters.

I did try the command line after editing the file manually and the BOINC message log instantaneously indicated the throttle kick in. My syntax in the DOS window is:

"c:\program files\boinc\boinccmd" --read_global_prefs_override

launched from a temp throttle.bat in the data_dir.

The override file of course located in same data_dir place as global_prefs.xml

But, I was born with Diti D'Oro so who knows.

We don't have the Flu, we have the Palmtree pest at the moment, nationwide. Thousands and thousands of Palmtrees all over Italy are dying. The one of two in our garden, the pride and joy in shade provision on the south west side of the house died within 4 weeks.

Here the file in full, as is:

Syntax errors in the cc_config.xml are printed in the message log. Never tried before, but put some wrong code in and nothing logs. Was reading that the developers were adding more lines to show in the message log for the global_prefs. With the GUI interface I guess there's they saw no reason to log errors.

edit: Rather duh, but why not delete your file and use the GUI interface to enter the needed field values? Then it's for sure correctly konzipiert.
