Hi everybody,

my problem:
I am running BOINC 5.10.21 on a Debian Etch QuadCore computer. As the server is needed for critical operations during the day I try to have different usage off the boinc-programm over the whole day. So I wrote a little "script" which loads specific settings at specific times:
--------
crontab shows:
0 0 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_high global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
0 1 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_ultra global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
0 10 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_high global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
0 11 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_mid global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
0 13 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_low global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
0 23 * * * cd /home/wcgboinc/BOINC/; cp global_prefs_override.xml_mid global_prefs_override.xml; ./boinc_cmd --read_global_prefs_override
----------
As an example for one of these config files:
global_prefs_override.xml_ultra:

<global_preferences>
<cpu_usage_limit>95</cpu_usage_limit>
<ram_max_used_busy_pct>4</ram_max_used_busy_pct>
<ram_max_used_idle_pct>8</ram_max_used_idle_pct>
<max_cpus>4</max_cpus>
</global_preferences>
---------------------
So I copy different global_prefs_overrides and run the --read_global_prefs_override command. In general it works fine exept one point.

Have a look at my MRTG site: http://85.14.220.37/mrtg/

Here you can see, that there are different level in usage over the whole day. But my problem is, that in the night, when my server could run at >90% on boinc it only uses two cores. As you can see above the settings should tell the computer to use all 4 cores. So the load is just half as maximum possible.

I think at the fist day on which I installed the programm it automatically used all 4 cores.

Any ideas how to get boinc run on 100% during night?

Thanks,
Leo
