Posted 4 Mar 2006 by KeeperC Post: Paul, I have no insight into the reasons you are quitting. What I can see is the contribution you have made to the benefit of all and your commitment to improving BOINC and the BOINC community and strengthening both. Thanks for all your contributions. |

WUs constantly failing
(Message 20098)
Posted 10 Feb 2006 by KeeperC Post: [url=http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=1612048]This[\\url] result and [url=http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=1351239]this[\\url] one, both on the same machine, failed at exactly the same point. The machine cannot get past this point in sulphur, despite having many successful slab models to its credit. Two of my other machines have also failed on Sulphur, though less repeatably. I must say that I find this problem quite frustrating. I know the team is focused on the new experiments, but if this undiagnosed problem persists with the coupled model, it will begin to sap my (considerable) commitment to this project. :( Edit: Sorry, can\'t remember how to put in links but you have the URLs at least. |

Posted 5 Feb 2006 by KeeperC Post: I hate to be brusk, but are any of the 4.22 models completing? I have had two machines having problems with 4.22 but two others not showing any signs of stress. So far, one completed 4.22 model and the next most complete nearing the end of phase 3. I don\'t take any precautions - no back-ups, never stop before defrag nor before shutdown. Internet on always. |

Hypothetical? funding plan
(Message 19765)
Posted 29 Jan 2006 by KeeperC Post:
Perhaps someone from the project could put this in context. What is the budget of the project? For how many years? How does it break-down into sub-projects, staff/overhead/hardware, etc? Perhaps the team could also suggest possible costs (including full oncosts and overheads) of a new research student? A programmer? etc? |

I don\'t think this is the case. If you look at the machine (325133), you will see that the most recent crash was on a model issued on 16th Jan, long after the batch of bad WUs was resolved. |

Results
(Message 18537)
Posted 21 Dec 2005 by KeeperC Post: What has happenned to the results on your account, mine has vanished. All the trickles from stage two and those just from stage three gone. Has the moderator decided to stop them showing or is it a fault? Carl has temporarily taken this information of the main account page. The reason for this was that the db queries for trickle information from increasingly many users were overloading the servers. By taking the info off, he could keep the servers online. Trickle info is still available from each individual result page but this does not give an overview. If the team can optimize the queries concerned, they plan to restore trickle info to the main page, but this may be some time coming. |

Caught in apparent CP processing loop after 6hrs on WU
(Message 17115)
Posted 10 Nov 2005 by KeeperC Post: CPDN\'s checkpoints every 144 timesteps (3 model days) and 4 minutes CPU time isn\'t going to be long enough to complete that unless your secs/TS is under 1.7 (which is extremely unlikely with a P4 2.8GHz). In other words, CPDN saves its progress less frequently than every five minutes. If you exit before it does a save (checkpoint) you will lose all progress back to the previous checkpoint. If you do this every time CPDN runs, you will seem to be in a perpetual loop, reprocessing the same time period. Two solutions: 1. As Geophi suggests, keep model in memory when inactive. This ensures progress is not lost even though no checkpoint has been saved to disk. 2. set a timeslice greater than required to guarantee at least one checkpoint per timeslice. If you just do 2. you will always lose some work - back to the last checkpoint. So it is always worth doing 1 as well. I would recommend both. |

question on backing up
(Message 16308)
Posted 28 Sep 2005 by KeeperC Post: Backup the whole BOINC folder. There are some BOINC files that log progress and you will crash if they get out of line with the application. You need to stop processing before making the back-up to ensure that the log files Andrew mentions stay consistent. |

BOINK Seems to crash
(Message 16262)
Posted 26 Sep 2005 by KeeperC Post: (why doesn\'t un-install delete the BOINK directory and files (Yawn)) Upgrading BOINC from 4.19 to 4.45 required a full uninstall of the old version followed by new install of the new. Leaving the BOINC directory in place allowed users to upgrade midway through a model without losing their work. |

Windows :
Cannot get work units
(Message 16188)
Posted 23 Sep 2005 by KeeperC Post: I think BOINC is insisting on downloading a sulphur model, and the problem is associated with these models. If you detatch and re-attach, you may just get a slab model instead, and there is no problem with these. You may subsequently need to merge computers because this process will create the newly attached computer as a separate machine from the old one. Merging is easy from your account pages (my computers) |

Got a computing error and after that I wasn\'t able to do anything, neither downloading nor computing work
(Message 16187)
Posted 23 Sep 2005 by KeeperC Post: The problem only seems to occur with sulphur models. Since no model is currently running, try detatching from the project and attaching again. If you are assigned a slab model instead of a sulphur one, the download will go fine. Do you know what caused your first model to crash, the one you thought was running finely? |

Sulphur Download?
(Message 16157)
Posted 21 Sep 2005 by KeeperC Post: Carl said My computer tried to download two sulphur models last night. Both errored out during the download of the zip file with \"file not found on server\". I emailed Carl detailed error messages today and his response was: hmmm, looks like boinc deleted the workunit files but is still trying to send out results for that workunit. I\'ll turn off the workunits/results that are pointing to missing files. |

New Work Request Before Phase Two
(Message 12282)
Posted 4 May 2005 by KeeperC Post: My Linux client (4.19) with HADSM 4.13, downloaded its new model at the end of Phase 1, too. At first, I thought the current model must have crashed, but it hasn't. The new model is just sitting, waiting patiently for the current model to finish. I hope the transition at the end of phase 3, due in three days or so, will go smoothly. |
