I just restarted a seti cruncher after being off for 3 days and I now see in Boincview that each of the 4 processors has "CPU limited to 50%".

Whats this all about?

My general preferences are set as follows:
Use at most = 100 percent of CPU time.

This install of seti/boinc is on a centos machine and it was running just fine 3 days ago...

Does the command "top" also show 50 % per SETI application per CPU ?
Could you please try to update your prefs via the website and do a update project via the BOINC manager.

Yes... Already issued "update" to no avail, and this morning its still limited to 50%.

Can you please verify your prefs (open a shell/terminal, cd to the BOINC directory and do a "grep limit global*xml").
Could you please also try to change of some variables at the prefs and reupdate it again.

Thanks Dotsch!... Running on all cylindars now. :)

Seen that it was set as 50... Odd, since this hasnt happened before.

I WANT to limit my CPU usage to 33% and the neither the local files or the global preferences are working.

If I start BOINC it runs all the time, not just when inactive AND takes 100% of the CPU. I tried to change what you asked but got this error.

I am running Ubuntu Feisty Fawn

/BOINC$ global_prefs.xml:<cpu_usage_limit>33</cpu_usage_limit>
bash: syntax error near unexpected token `33'

Thanks In Advance

That's only because no other processes are after the CPU. Or would you rather the CPU sat there looking bored & twiddling its thumbs? ;)

Linux resource management actually works, unlike that other OS where the user is often lumbered with making sure there's enough 'spare'.


Here's a trivial demo of it in action.
Open two shell windows and in one, run 'top'.
In the other, run something fairly busy like:
find / -type f -exec grep dummyword {} \\;

This harmlessly and inefficiently wastes time & resources trying to find the word "dummyword" in every single file on your disk. (ignore the 'permission denied' messages; they're expected)
While it's running, watch what happens in the shell running 'top' - notice how the CPU usage for seti changes?

Use Ctrl-C to kill the resource-waster and type q to exit 'top'.

Don't worry, it's fine. You can drop all that other OS baggage now. ;)

To err is human; to moo, bovine.

BOINCView showed me that one machine was CPU limited to 40% vice the 75% intended. Configs on all web sites were fine.
Your hint, led me to check my global_prefs.xml which was fine.
However, in global_prefs_override.xml it was set to 40 vice 75.

I'm on MS2K vice Un*x. I do have vi editor ya!! But don't have grep on this MS-slave so it took a few more steps plus lots more mouse work than a Un*x shell requires to find and change value!

How did I get into the Unix/Linix message board?
Quick, get me back to my MS cult family ;) LOL
