If this is the actual text, there's a typo.

<max_ncpus_pct>50.0</max_ncpus.pct>
should be
<max_ncpus_pct>50.0</max_ncpus_pct>


Ah... sanity is restored. Thank you!

Sorry... as the title indicated, this is a headless box - no GUI.

I presumed restarting BOINC would cause the global override file to be read. Is that not the case?

That said, I ran "boinccmd --read_global_prefs_override" - and not seeing any difference.

Hi all. I'm trying to limit cpu usage to half of the available CPUs on a couple of larger hyperthreaded Linux boxes.

In the BOINC directory, I've created a global_prefs_override.xml:

<global_preferences>
<cpu_usage_limit>50.0</cpu_usage_limit>
<max_ncpus_pct>50.0</max_ncpus.pct>
</global_preferences>


But on a 32-thread box, BOINC is still spawning 32 processes. Likewise on a 56-thread server (spawning 56 processes).

Any suggestions?
