Number crunching :
YAFU for small composites
(Message 1907)
Posted 23 Apr 2026 by Aurum Post: Wuprop says that YAFU for small composites had 1,076 WUs in the last 24 hours. https://wuprop.statseb.fr/active_projects.py For the last several weeks I've only caught a couple with my Linux BOINCers. Are they just for Windows? I had preferences set for 1 CPU. I just changed it to 2 CPUs and 4 CPUs and got a few. |

Aliquot sequence 2175894 has terminated!!!
(Message 1559)
Posted 25 Mar 2021 by Aurum Post: I learned what an aliquot sequence is. So did this sequence start with the divisors of 2 million 175 thousand 894 excluding 2,175,894??? |

Is it possible to run yafu-4t tasks with 8 cores?
(Message 1557)
Posted 18 Mar 2021 by Aurum Post: Try it and let us know. I predict no. <app_config>
<app>
<name>yafu-4t</name>
<max_concurrent>8</max_concurrent>
</app>
<app_version>
<app_name>yafu-4t</app_name>
<plan_class>4t</plan_class>
<avg_ncpus>8</avg_ncpus>
<cmdline>--nthreads 8</cmdline>
</app_version>
<app_config>

Posted 25 Dec 2019 by Aurum Post: If you want to attempt to tame this beast put this in your app_config: <app_config>
<app>
<name>yafu-32t</name>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>yafu-32t</app_name>
<plan_class>32t</plan_class>
<avg_ncpus>32</avg_ncpus>
<cmdline>--nthreads 32</cmdline>
</app_version>
</app_config>Then restart it:/etc/init.d/boinc-client restart |

How do I get YAFU to stop sending me tasks that use up 100% of my cores?
(Message 1344)
Posted 27 Dec 2018 by Aurum Post: Hi YoYo, When you define your own class plans (<plan_class>16t</plan_class> & <plan_class>32t</plan_class>) don't you have to pass the client your plan_class_spec.xml file??? https://boinc.berkeley.edu/trac/wiki/AppPlanSpec This app_config.xml is not working to control number of threads used: <app>
<name>yafu-16t</name>
</app>
<app_version>
<app_name>yafu-16t</app_name>
<plan_class>16t</plan_class>
<cmdline>--nthreads 16</cmdline>
<nthreads_cmdline>1</nthreads_cmdline>
</app_version>
<app>
<name>yafu-32t</name>
</app>
<app_version>
<app_name>yafu-32t</app_name>
<plan_class>32t</plan_class>
<cmdline>--nthreads 32</cmdline>
<nthreads_cmdline>1</nthreads_cmdline>
</app_version>My client_state.xml file says:<app_version>
<app_name>yafu-32t</app_name>
<version_num>13401</version_num>
<platform>x86_64-pc-linux-gnu</platform>
<avg_ncpus>40.000000</avg_ncpus>
<flops>122619847136.720169</flops>
<plan_class>32t</plan_class>
<api_version>7.1.0</api_version>
<cmdline>--nthreads 32</cmdline>And 32t still takes all 40 CPU threads. https://boinc.berkeley.edu/trac/wiki/AppPlan#Predefinedplanclasses BTW, can't see the check marks in my Yafu Preferences Run only the selected applications. |

Posted 26 Dec 2018 by Aurum Post: I think your app_config.xml should be more like: <app_config> <app> <name>yafu-8t</name> <max_concurrent>4</max_concurrent> <fraction_done_exact/> </app> <app_version> <app_name>yafu-8t</app_name> <plan_class>mt</plan_class> <cmdline>--nthreads 12</cmdline> <avg_ncpus>12</avg_ncpus> </app_version> </app_config> I suspect <avg_ncpus>12</avg_ncpus> is not needed if <cmdline>--nthreads 12</cmdline> is issued. Edit: Tried it sans <avg_ncpus> and Yafu wants every thread I've got. Need to include it.
