Ecm on ARM requires too much memory

#1 Ungelesener Beitrag von sorcrosc » 20.12.2016 23:17

I have been able to get and complete successfully a work unit some day ago:
http://www.rechenkraft.net/yoyo/show_ho ... tid=343777


But now I can't get them anymore:
mar 20 dic 2016 23:01:59 CET | yoyo@home | ecm needs 2098.08 MB RAM but only 1712.83 MB is available for use.
Any change?

The different ecm tasks have different RAM requirements. It seems that the currently existing tasks in the queue require too much memory for your ARM. The scheduler will not send those to your system, because your system has too less RAM.
But new ECM are created frequently and also resents are available.
So there will be also ECM tasks available with less RAM requirements.
HILF mit im Rechenkraft-WiKi, dies gibts zu tun.

Can you reduce the timeout after BOINC does not get new Workunit because of RAM? Currently BOINC waits 24 hours after not getting any WU's because of the RAM requirements.

No, this is done by the boincmanager.

I use this app_config.xml to limit the number of workunits to run simultaneously. This prevents memory problems. I think 2 workunits are relatively safe with 2 GB of ram.

Code: Alles auswählen

<app_config>
   <app>
      <name>ecm</name>
      <max_concurrent>2</max_concurrent>
    </app>
</app_config>
