You may also want to check the CERN Grafana pages:
LHC@home menu -> Jobs -> CMS Jobs -> Running Jobs

If you are running CMS tasks but the most recent number there is down to zero you are wasting cycles with empty envelope tasks.


Thanks for the tip. I managed to register an "outsider" account there and I see 500-600 jobs in the "production" category. I assume that means all is good. I do have a question though. The BOINC-based server status page shows over 10k tasks in progress. Why the huge discrepancy? Does it mean that most tasks running are envelope tasks?

These are tasks that are sent to the client but not yet started.
When a VM (task) starts it registers via WMAgent/HTCondor to get a job.

BOINC server shows # sent tasks
Grafana shows # registered jobs

Apologies. I didn't catch the last batch before the job queue drained. A new batch is in the system but it will take an hour or two before a) jobs get into the condor pending queue, and b) BOINC server sees there are new jobs available and starts creating new tasks in the task queue.
Edit: Ha, spoke too soon -- new jobs/tasks are already available!

Yes. Looks like the JobSubmitter component in the WMAgent died around midnight. We've restarted it, and jobs are starting to run again.

Hi; The vccs-dev machine had been removed from the firewall. Laurence reinstated it, and I now have a job successfully running, so try again.
