Hello,

i made my system new - using bullseye. The system before was buster.

On buster - the boinc uses 8 processes.

On my new bullseye it uses only 1 process.

#top
66939 boinc 39 19 110996 13224 2468 R 1066 0,2 10:29.01 milkyway_nbody_

I am using the following "Global configuration" from boincstats:

Picture of my Global Configuration

and my cc_confix shows:

root@# cat /etc/boinc-client/cc_config.xml
<cc_config>
<log_flags>
<task>1</task>

<cpu_sched_debug>1</cpu_sched_debug>
</log_flags>
<options>
<ncpus>12</ncpus>
</options>
</cc_config>

My boinc-Messages-List shows:

Are you sure it's only using one thread?
According to Milkyway@home the N-Body Simulation tasks are MULTI-THREAD noted by the (mt) designation. It will use all threads or as many threads you specified in your app_config.
