You can also run it with fewer cores, but it is not really suitable when also running other CPU pojects.

You need to change cc_config.xml to 16 cores with the following:
<options>
<ncpus>16</ncpus>
</options>

Then you must create an app_config.xml file in the projects folder of yafu with the following:
<app_config>
        <app_version>
                <app_name>yafu-16t</app_name>
                <plan_class>16t</plan_class>
                <avg_ncpus>16</avg_ncpus>
                <cmdline>--nthreads 8</cmdline>
        </app_version>
</app_config>

The 16 is what BOINC will think it uses and 8 are the real cores of the machine.
You have also to realise that the deadline may be to short when using not enough cores.
