It doesn't look like there'll be any EU models left by Monday morning, All gone.  Possibly deprecated by one of the project people, as requested by a moderator. Backups: Here |

Why never test these loser WUs before testing the volunteers bandwidth? Dear Mr Redd, I certainly do dare to apologise for the inconvenience and annoyance that the current round of problems have caused you, and all other supporters of CPDN. The recent Hadam3p release was, as far as I am aware, produced in exactly the same manner as previous hadam3p releases (which have been running successfully). I apologise for the wasted bandwidth that we have caused. We have been made fully aware how much this has upset people, and we will, in future, take steps to minimise these problems. I will be posting an apology on the news items on this site on Monday. Finally, I would ask that, annoyed as you obviously are, please don't abuse the project staff. Jonathan Miller CPDN System Administrator |

Two latest regional models crashed in 9 and 10 seconds respectively. Even faster than the 45ish seconds from the last few I have had! |

We have been investigating the problem with the Hadam3p work units. It appears that the crash is caused by the combination of two perfectly normal forcing files. The SST and SI files were altered in the previous suspect run. If either of these files is substituted for the previous version, the model runs perfectly well. The crash only occurs when both files are specified as inputs to the same work unit. We are conducting tests on the Met Office UM in order to try to find out why this should be the case. In the mean time, the current release of Hadam3p work units are resubmission jobs of proven work units. These should be fully functional since we are extending the duration of previous experimental runs. Jonathan |

Thanks Jonathan, a suplementry question I have is are there enough work units going out yet to lose the restriction as having had these two latest fail I can't get any more till tomorrow? It is a question and I can live with it if the answer is, "No" Dave |

The answer will be no, as there are still at least twice as many computers attached as there are models. However, looking at your list of computers, (where it's a bit hard to tell just how many you have), I think that it's possible that they're too old, as per this thread at the top of Number crunching. All of the current work requires SSE2. Backups: Here |

Thanks Les, all except the two computers with recent credit don't exist any more and are sse2 compatible. I will spend some time deleting the old ones to clear up any confusion. Dave |

I posted last from a different computer than this. - Looking at tit it is an old identity and the computers listed on it don't exist any more. Only two of those on this loggin are still relevant to the project and these are sse2 compatible. |

Dave A bit more on your post about not getting more models until 'tomorrow'. There are now 2 different delays: 1) If a computer crashes models serially without returning one that's successful, then the Maximum daily WU quota per CPU will keep being decreased until it reaches zero, at which point the computer has to wait until midnight project time, (in the case of cpdn, this is UK time), to get another model. This is to slow down serial crashers from wasting too many models. 2) A newly introduced delay, of a 1 hour backoff between requests, to try and spread out the limited amount of work. Each time the computer contacts the server for ANY reason, this delay is reset back to 1 hour. Only a request made after the countdown has timed out will be considered for the allocation of a model. IF any still remain at that point. This delay is not dependent on waiting until the following day. Backups: Here |

A new batch of regional models were created over the weekend, all of them regens from previously completed work, so they should be OK. Sadly, the 2 models downloaded to mine from this latest batch have both experienced the 45 second crash, so it looks from this end of the telescope as though the problem is still extant. |

The same thing has happened to me on the two computers I have running CPDN - one a Windows 7 machine, and one an iMac. I don't want to be rude, but was this batch of models tested before release? iMac tasks: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7539655 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7535832 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7535713 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7539464 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7535460 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7535459 Windows tasks http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7537097 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7536546 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7539251 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7536772 http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=7535216 Derrick Ashby |

I leave a message for the project people for when they're out of bed and at work. For anyone else who wants to provide details, it's preferable to use links such as Byron and Darmok, as it saves having to go to each linked model to see the name. Backups: Here |

Hmmm. It looks like there's a 2 series, and a v series. Not long now until they're back at work. Backups: Here |

It is sad - the project gives second batch of permanently corrupted work units, typical error messages are like these:

 It looks like all of them are faulty. To much pressure to produce work units, especially late in the week. More later. In the meantime, everybody put away the axes, knives, halberds, and spears, and go home. Backups: Here |
