CMS running jobs are falling. I haven't seen anything yet. Anyone? A link to a failed WU?
It's way past my bed-time. See you in 6+ hours and hope it's a false alarm...

That shouldn't have started to affect us last night,
In any event, the trend didn't continue. We've fewer jobs running now, but still more than this time last week.

I guess, the high numbers last week were down to the fact, that Theory was down.

Exactly. Laurence, Ben, et al. opened CMS@Home up to "production" status at vLHC@Home so users there started gobbling down jobs. For a while we nearly tripled our previous job rate, we're now settling down at about twice.

BTW, the new workflow we've been running the last month or so is now approaching 10 billion events processed. I've heard back from the people who requested the jobs that the results look good, but no reports of analysis data yet.

It is nice, that it is actually being used. Unlike Seti, where it is very doubtful, that there will ever be a "result" of any kind.

We're not sure where that is coming from. Other monitoring doesn't show a problem. It went away after a while, but may be coming back.

Has anyone spotted where the sudden increase of running CMS jobs today has come from? I checked earlier and there wasn't a spike in new sign-ups in -dev or production projects.

There was an issue with the Theory jobs so CMS has stolen some extra resources :)

EDIT: Shouldn't this be in an anti-dip thread?

You may have noticed a reference to my trip to Ambleside last week for a collaboration meeting for GRIDPP, the organisation of Universities and Laboratories which runs the UK Grid computing network for the LHC experiments (plus some extra for other science projects).
I gave a talk on CMS@Home, including a partial analysis of the data we have been generating. The talk is publicly available, though obviously without my running commentary on the slides. You should be able to view it as PDF or PowerPoint(TM).

No jobs?

I am trying a new OS.

Is it me, or is there a problem?

There are jobs. I'm puzzled by the dip, I'll take a closer look.

No, that must be a red herring. I've got a CMS job now and it's running -- admittedly on the production project, not here on
-dev
. So, jobs are available.

It might be a reporting problem again. The graphs we use for CMS Jobs show job completion down to ~40/hour but I'm seeing twice that on the condor server, though it was down a bit earlier on, but still above 60/hour. For the last three full hours:
[cms005@lcggwms02:~] > ls -l 160903_112049:ireid_crab_BPH-RunIISummer15GS-00046_T/job*.txt.gz|grep '7 20'|wc
85 765 10285
[cms005@lcggwms02:~] > ls -l 160903_112049:ireid_crab_BPH-RunIISummer15GS-00046_T/job*.txt.gz|grep '7 19'|wc

Yeah, that was my mistake. Somehow I misread the queue status last Friday night, after a rather stressful day, and went to bed without submitting a new batch when I should have... Woke up to find it empty, so a quick CRAB3 submission of another 10,000 jobs quickly ensued. That reminds me, I'd better submit a new batch tonight, too!

There is something definitely wrong with the Dashboard reporting. The headline numbers on the "CMS Jobs" page come (in)directly from the condor server and correspond with what I see when I log into the machine. The Dashboard plots are not consistent with those data. I see the number of jobs in WNPostProc reported by Dashboard are much higher than usual, but I'm not sure if that's enough to account for the discrepancies.
I still think it's a Dashboard communications problem.
