Hi. I just changed laptop to a new Lenovo T410, with an Intel i5 cpu. According to the intel webiste, it'a dual core, each core with hyper threading, so I expected Boinc Manager to run at least 2 tasks, if not 4.

On the contrary, it's only running one, with 25% CPU usage. About preferences, I have boinc with 'Run Always', so it should be performing better...

Here is the output from boinc manager:

Any idea what can be wrong?

How much work does it have on board?
About those preferences, what's the setting for "On multiprocessors, use X% of the processors"? This one will be used, no matter if you set Boinc to run Always or based on preferences. If not set to 100%, that'll likely be your culprit.

Oh...!!!! Boinc manager is such a liar!!!!

I changed that from the default '0.00' to '75.00' and now it's running 3 tasks!

Thanks a lot...

anyway, I think the options should be renamed... it's confusing to have a 'run based on preferences' and a 'run always' which (at least for me) makes me believe that NONE of the preferences will be used for the 'always' option...

Regards,

Leo

Think of it this way, it doesn't say Run Overriding Preferences. Just Run Always. That's there if you don't want to use the time-of-day or other suspending preferences, for whatever reason you have. .
