Hi there.
We have a handfull of Raspberry Pi 3's that we would like to use to crunch Seti@Home with boinc client.
boinc has been installed in raspian with apt-get, and the version is currently 7.4.23.

Currently when i do a "ps", i see two cpu's running at 100% using boinc, and two ideling.
I would like to run all cpu's at close to 100% (still need ssh access, though).

I have spend a few hours NOT figuring out how to set the cc_config.xml up correctly to do this.
Could someone please tell which switches i need to set to make all 4 cores run at max.
Note: I only have ssh access to the rpi's, no physical screen.

Thanks :-)

i have 3 cores working and 1 idle. i havent figured out how to get the other one working.

CPU core amount is set via global_prefs.xml or when in use global_prefs_override.xml with the <max_ncpus_pct>N</max_ncpus_pct> value set to 100 for 100% of CPU cores. The older <max_cpus>N</max_cpus> value isn't used by BOINC 7.

global_prefs.xml is essentially what you set via the project's computing preferences.
global_prefs_override.xml is set either via the BOINC Manager GUI, or made by hand. This latter version will as its name suggests override the other preferences (file).

this is what i have from computing preferences

Signature space for rent. Spacious lot available immediately. Includes utilities. Inquire within.

Looking at the tasks it returned, you are running 4 tasks at a time, else it's not possible that it returned 4 tasks on the 6th of August, all with run times of about a day.

im a idiot lol. the 4th one is doing WU's. Its not updating the status in real time, only when you click on it. possible bug?
