LHC@home

We have an upgrade pending for the WMAgent which controls our job batches. Therefore I have to drain out the job queue. I will not submit any new batches for now. The current batch should drain late Sunday or on Monday; I'll try to keep an eye on the queue and let you know when to set No New Tasks, but if you see no jobs available stop your tasks on your own initiative. I will of course announce when new jobs are available again.

Thanks for the announcement.

Thanks for the warning, Ivan. It's not easy for those who run different combinations of LHC jobs on different hosts to stop only CMS, so will this result in the BOINC server just not sending out CMS jobs (Laurence's fix) ?

I hope so, but I'll remind him just in case.

OK, many thanks.

At the moment we seem to be on target to drain out late on Saturday. I'll check out the situation around noon that day, and maybe submit a smaller batch of jobs to keep us running until Monday to fill in the gap before Alan can do the upgrade. It's a bit fluid; I'll keep you informed.

---

We were starting to run out of jobs this morning, so I submitted a small batch that should tide us over until late tomorrow.

---

The queue is draining again, so we'll be out of jobs in another couple of hours. I'll not submit any more to make sure we mop up as much of the"tail" before tomorrow morning.

---

Why are tasks still being sent out if there is no work to do? Nothing but 207 (0x000000CF) EXIT_NO_SUB_TASKS for 8 hours.

Looks like the empty-queue detection didn't work as expected and tasks kept being created.

Well, the update has been completed, late into the night (Thanks, Alan!), and I've submitted a small batch of jobs. However, I don't think that volunteers machines are picking them up; I suspect that the CMS task creator didn't start up automagically when jobs became available. Or, there's another problem that will require manual intervention. I'll go to bed soon, and hope things straighten themselves out in the morning.

---

Task creation is on again. I've just received my quota on all my PCs. There will be some confusion in the Jobs graphs until we get the new configuration completely sorted.

---

We seem to have a little problem with the WMAgent again. A component has failed and a new batch I submitted is not starting up so the queue is starting to drain again. This is likely to do with work we've been doing behind the scenes to integrate CMS@Home more tightly with CMS Job Production.

---

All OK again due to swift action at CERN.

---

I'm draining the queue for another WMAgent upgrade. Jobs should start drying up in about 10 hours or so, so consider setting No New Tasks for your CMS instances sometime in the next 10 hours, or when you see your tasks failing to pick up jobs. I'm hoping the upgrade can be done first thing tomorrow, so hopefully back on the air by about lunch-time.

---

We are back up again now, so please resume CMS tasks.

---

Yes, Job's are running well!
Thank you Ivan for the upgrade.

Have a question because of old Job's from January and February in my Computer stats, but not from March.
Some with Errors and some are finished.
Also in Theory.

There's a WMAgent upgrade ready for installation, so I'll try to get the queues adjusted so that we drain out around Sunday night. So be prepared for a period of no new jobs Monday-ish (set no new tasks, etc., as you wish).

---

Once again we need to pause for a WMAgent upgrade. I won't submit any new jobs this weekend -- I estimate we have 30+ hours of work in hand, plus the usual stragglers, so hopefully Alan will be able to do the upgrade on Monday.

Thanks
