Multicore Shutdown
A new feature has been implemented to shutdown multicore VMs at the end of their life when the idle time > busy time. This means that if we are wasting more time with empty cores than we would loose by kill the remaining jobs, those jobs are killed. This should avoid the situation where a looping Theory job keeps the VM alive while wasting idle cores. If this works the following message should be seen in the task output.

Multicore Shutdown: Idle > Busy ( 1439s > 1382s )


Let me know how it goes. 12 Sep 2017, 13:07:26 UTC · Comment

Server upgrade
We will migrate the lhcathome-dev project to a Centos7 server and upgrade the BOINC server components.

The lhcathome-dev project server will be unreachable for a while later today during the upgrade.

CMS application job queue is being run down.
We want to update the WMAgent job controller, so I've stopped the next batch (I hope). We should run out of jobs in 10-12 hours, so set any machine running CMS tasks to No New Tasks as soon as practicable. Should be up again tomorrow. 26 Jun 2017, 16:00:39 UTC · Comment


CGI testing
We are trying to improve the job limiter that is currently active, so you might experience some instabilities for the rest of the day.

Thank you for your understanding.
