<max_ncpus>N</max_ncpus>
An upper bound on NCPUS (default: 64)
(which is why during the test I never got past 64 threads)

http://boinc.berkeley.edu/trac/wiki/ProjectOptions


read N from
On multiprocessors, use at most 2 processors

from

When and how BOINC uses your computer Computing preferences

N=setting
in this case the on multipro.... use at most 2 processor

therefor N is replaced with 2.

yafujobmt_0.04.xml


<job_desc>
<task>
<application>yafu</application>
<stdout_filename>out</stdout_filename>
<command_line>-threads "2" -batchfile in</command_line>
<multi_process/>
<checkpoint_filename>nfs.dat</checkpoint_filename>
</task>
</job_desc>



or however you change a dynamic argument to a static

$NTHREADS=2


client_state.xml would look like
