Ivan, are you aware that no CMS tasks are available? Erich; sorry, I've just noticed that myself (fell asleep in a nice warm kitchen... Not sure how I missed your message earlier tho'). I'll send out some emails, other projects are also affected if the Server Status Page is to be believed.  |

It's the task creator that's the problem as far as I can tell. The job queue is alive and well, and the WMAgent shows no problem. I've emailed the general production crew but maybe it's exactly the wrong time of the week to expect a response. :-( |

There are tasks available again -- I just got one on my home PC. |

Ivan, there are new tasks availble (according to the Project Status Page), and obviously there are also jobs available. Still, as seen here: https://lhcathomedev.cern.ch/lhcathome-dev/cms_job.php the number of "running jobs" has been falling markedly within the past hours. Why so? To me, this does not look like a "natural" fluctuation.[/url] |

Yes, I asked about that and it is believed to be linked to some Condor maintenance -- see this thread. I seem to still be getting tasks and jobs; I suspect that it's Lawrence's machines that are running out. There is no increase in failure rate in WMStats. Unfortunately the graphical application I use to track running and queued jobs has been down since yesterday, so I only have WMStats and the CMS Job page to monitor progress. Oh, the proxy we use has been showing no activity since 0900, too. |

We seem to be slowly picking up jobs again. |

We seem to be slowly picking up jobs again. YOW I forgot this is a 982.17MB vdi ........this will take a while but as long as they run Valids after I get them running on this 8-core that is ok.........especially since I won't be home for a rare few hours today while the d/l is happening.........can't let Ivan run ALL the CMS tasks  Volunteer Mad Scientist For Life

We seem to be slowly picking up jobs again. Are you running any sort of local caching proxy? That could greatly reduce your downloads as most things would only need to be fetched once. computezrmle sent me a recipe on how to set it up but now I have a 40 Mbps link at home I don't need it (I have 1 Gbps at work, but we're throttled to 30 Mbps and some machines are still on a 100 Mbps switch). |

Yeah I tried that before but it doesn't help me and my satellite dish isp.....now if they would just send me a disc with the files in the mail I could just install in seconds  Read lots of squid info and also comments on both sides of that subject. So I just d/l the vdi and then getting tasks and running them are fast and easy. In fact it would be easier if I copied the vdi to disc here and then install it on the other pc's here. Edit: just checked and it was only one hour to get to 50% so that is faster than usual during this time of day (I do have high-speed between 2am and 8am but I save that to make sure the VB tasks will get past HTCondor ping) |

Digits cruciate! There are now some merge jobs running, where there had been none for a couple of days. These only run on Laurence's CERN VMs because the bandwidth required is not compatible with home volunteers. So, it looks like at least a few (8 at the moment, to be exact) of these machines have come to life. I hope that means that someone has tickled them back to awareness -- Laurence has been on paternity leave :-) for the last week or so so it's been difficult to contact him :-(. |

Ivan, it sounds to me like Laurence is just trying to make us all feel old  Last time I created another human was 1982 (ok I decided I better not comment on that disaster)   (ok I still have all my hair and it is not all gray yet).....but I do have all 50 cores running now!Volunteer Mad Scientist For Life

Well, all merge jobs from the last batch have run, and we are up to around 1250 jobs running at the moment, so something has definitely sprung back to life. |

... so something has definitely sprung back to life. It seems that this "something" returns lots of errors: https://lhcathome.cern.ch/lhcathome/cms_job.php :-? |

good morning, Ivan BOINC says "not CMS tasks available" :-( |

good morning, Ivan I'll take a look in ~30 mins when I get in to work -- running a bit late this morning... [Edit] One of my monitoring tools that's been dead for a week has just sprung back to life -- that should make tracking the queues easier! [/Edit] |

Ivan, could you find out yet why there are no tasks available for CMS? |

Ivan, could you find out yet why there are no tasks available for CMS? Are you not getting any? I've been getting them again since 1433 yesterday. [/Edit] I see you got some at 2003 last night. PEBKAC? :-) [/Edit] |

Are you not getting any?I got tasks during this day, but now again it says "no tasks available for CMS simulation, although the Project Status Page shows about 190 unsent. |

Edit: just to find out, I tried to download a Theory task and a LHCb task, for both plenty of unsent should be available according to the Project Status Page.Are you not getting any?I got tasks during this day, but now again it says "no tasks available for CMS simulation, although the Project Status Page shows about 190 unsent. However, no success either. So something seems to be wrong somewhere. EDIT: now, all of a sudden, new CMS tasks were downloaded :-) |
