Crystal Pellet, in your list, I have one "ppbar jets 1960 37 - sherpa 2.2.6 default" succeeded. |

You could add to this list: There's 1 success in MC Plots database for that description. |

Crystal Pellet, in your list, I have one "ppbar jets 1960 37 - sherpa 2.2.6 default" succeeded.Thanks, the list was based on 'only' 8 attempts for each description, but it seems more attempts could result in a success and your's was a fast one: 3 hours and 22 minutes. One may build an own list from http://mcplots-dev.cern.ch/production.php?view=runs&rev=2363&display=all and filtering on keyword sherpa. Edit: reduced the previous sherpa list from 613 to 577 occasions. |

hello Crystal Pellet, There is a "boinc ee zhad 206 - - sherpa 2.2.8 default" on one of my machines, NOT contained (yet) in your list - 22 hrs 35 min elapsed, 1108 days left (number is increasing); I guess I can abort this task, right? P.S. I just found it in http://mcplots-dev.cern.ch/production.php?view=runs&rev=2363&display=all with 54000 / 18 / 3 / 5 / 10 but still, the increasing number of "days left" is indicating a failure, isn't it? |

There is a "boinc ee zhad 206 - - sherpa 2.2.8 default" on one of my machines, NOT contained (yet) in your list - 22 hrs 35 min elapsed, 1108 days left (number is increasing)When it's not in 'my' list, it will never come on it. 3 successes. It's up to you to gamble between a great disappointment and great satisfaction ;) Increasing left time means not always that a task will end in an error, but that it's surely a heavy task. I, myself have seen successes after such an increasing left time suddenly jumping to event processing. |

One may build an own list from http://mcplots-dev.cern.ch/production.php?view=runs&rev=2363&display=all and filtering on keyword sherpa.Out of interest, what does the "2363" refer to? For "PbPb heavyion-mb 2760" I get run events attempts success failure lostbut 265306266 is still running and reporting "events processed" to the log (I'm estimating an 80-hour run time). Or is lost a badly-chosen euphemism for still running? |

Out of interest, what does the "2363" refer to?That is the revision of MC Production -> http://mcplots-dev.cern.ch/production.php?view=control For "PbPb heavyion-mb 2760" I getNo, probably not. In theory you could be right, but a task would be running then for weeks and weeks, I think.run events attempts success failure lostbut 265306266 is still running and reporting "events processed" to the log (I'm estimating an 80-hour run time). I don't know when a job is declared lost (No return, but since when?) The last number of your job description (after the # events) is the attempt sequence. It will be something like 40 atm. In the list it's still 10. |

Thanks. The last number of your job description (after the # events) is the attempt sequence. It will be something like 40 atm. In the list it's still 10.The answer is that it is, of course, 42! See other thread. |

Should I get worried by now? No - as long as there are no Vogon ships around. Just prepare a towel. |

I think that's my point - it looks like lost (which has negative connotations) is being used for everything which hasn't yet returned a success or failure, which could be for entirely reasonable reasons such as still being queued or running.Or is lost a badly-chosen euphemism for still running?No, probably not. In theory you could be right, but a task would be running then for weeks and weeks, I think. |

Try to grep the log file for events or elapsed - this can make it easier to see if there's any actual progress. But a continuing stream of ISR_Handler errors is usually a bad sign in my experience. |
