Number crunching :
Credit updates?
(Message 49442)
Posted 27 Jun 2014 by Niall Post: I'm still trying to get my head round the fixation on credit. Maybe I'm just more focused on extrinsic value. Maybe my sources of gratification lie elsewhere. When I can trade in my credits for book tokens (in our dreams) I might get a little more concerned about it but, for the moment, it's just not a priority. You see, without something to do with the credits, there's no point having them. Look, there are a lot of valuable projects on the BOINC system. Only one of them is a real social game changer, but that depends on finding a possibly non-existent needle in a very large haystack, possibly using the wrong tool for the job. The rest, yes, they all have some level of social and/or scientific value. Climate change is, however, the one big issue of our time, perhaps the thing that will make or break our civilisation. The rest are irrelevant if we don't act on climate change. That said, some really bad news is locked in to the system as a result of prior activity, even if we do stop being completely ****ing stupid as a species and cut our GHG emissions to net zero NOW. A better understanding of atmospheric physics and climate change is crucial to predicting what's coming. It might even help to get the politicians to take the kind of action that's required. Precisely what that entails is up to some people who know a lot more about atmospheric physics than I do. I'm going to take their word for it that the research is valuable, worthless bead-tokens or no worthless bead-tokens - because stopping the entire global ecosystem having an unscheduled critical excursion. That's what matters. |

ANOTHER UPLOAD PROBLEM
(Message 49425)
Posted 26 Jun 2014 by Niall Post: I'm having exactly the same problem. It's been an intermittent issue for a while, and we know there may be temporary server issues while the tech crew work on them. http://www.climateprediction.net/possible-server-issues-in-june/ The files have always cleared eventually, and see no reason why the same will not apply. The clue is in the words "transient" and "temporarily". The crunch continues. |

Number crunching :
Credit updates?
(Message 49416)
Posted 25 Jun 2014 by Niall Post:
Yes, I agree. False comparison over points is meaningless when we're using different machines, and some have access to several. I'd like to see more in the science thread. There were interesting posts about the UK flooding attribution, and an indication that there would be more data pooled in to it later as the last results came in, but it's gone silent. I wonder if, with the rest of the work units, the probabilities have changed. There has been nothing, to my knowledge, on the drought attribution in ANZ, and I've done several of those WUs. I'd love to know I'd contributed to evidence that King Coal Abbott is wrong because, ultimately, we're wasting our time if this doesn't contribute to policy change. On the other hand, the scientists are also probably incredibly busy, so this is more a matter of "at some point, when you get round to it, it would be nice if someone could let us know what these data are being used for and what the implications are" rather than a demand. Fixing the credit script, not so much. The work units will continue to be crunched regardless. |

Credit updates?
(Message 49410)
Posted 25 Jun 2014 by Niall Post: I've been ignoring this thread, but it's late (well, the small hours) and I can't sleep. I have to say that the question of credit updates is a matter of the most profound indifference. I can see that a minority of people, running multiple office computers, may be using these to alert them to problems with their own machines and how they handle BOINC but, for someone like me who joined relatively late, and with a good but hardly top-end laptop, I'm never going to be able to compete on points with those people. I'll contribute what I can. I can see from my own user record that I've added a small addition to the total. The laptop can't run any faster. The project, meanwhile, does not hire script kiddies. Their programmers have better things to do, like ensuring the servers stay online and ready to handle vast quantities of fluid dynamics data (I currently have a .zip sitting on my system that just will not upload, not for the first time, even this week). I couldn't get in to the message boards over the weekend. I rely on those to ensure nothing untoward has happened to the project, like the upload of the wrong files, and to give me some feedback on what my computer's hard word is being used for. I think it's much more important that they concentrate on jobs like those than worry about a points system that just promotes unfair comparisons. Someone nursing along a old single-core PC won't keep up with my laptop, but my laptop will never keep up with someone with access to a 64-core workstation, so I'm not going to worry about it, and I'm not going to nag the tech crew over it when they have better things to do. |

No Tasks Available
(Message 49286)
Posted 2 Jun 2014 by Niall Post: I'm on 100% renewable energy. Due to the economics of electricity production, unless you are either off-grid or on a 100% renewable local grid, demand reduction also counts. This does complicate things when running the processors harder to compute complex fluid dynamics models adds to power drain on the computer, but the latter would seem to be an acceptable compromise. I'm also getting my electricity from a company generating only through renewables, but it's provided through a pooled national grid, and it's a pretty still night. |

First Results in from Weather@Home 2014 UK Flooding Experiment
(Message 48975)
Posted 30 Apr 2014 by Niall Post: Okay. This is me being confused about the distinctions (or lack of same) between: * Ongoing ensemble runs (see the about page) and * the winter flooding attribution study. Those hadam3p_eu WUs on my hard drive will add to the ensemble data and may be used for improved analysis of the winter flooding attribution question? |

(Message 48972)
Posted 29 Apr 2014 by Niall Post: Up until the past day or so several thousand hadam3p_eu WUs have been on the server. I have three of them here. If you're presenting the results of the study, does this mean you don't still want these WUs done, or will they go in a later paper? |

(Message 48477)
Posted 20 Mar 2014 by Niall Post: One of your crunchers here. So, looking at this, it would so far seem that we cannot (yet) attribute the recent flooding to climate change? Bonus questions: Do the models we are running take into account the perturbed jet stream and/or the higher than normal sea-surface temperatures in the Pacific and, if so, to what extent can we be confident these are linked to climate change? http://www.metoffice.gov.uk/research/news/2014/uk-storms-and-floods Feel encouraged to elaborate your answers with reference to published papers.[/i] |

Model crashed: INITTIME: Atmosphere basis time mismatch

Posted 19 Mar 2014 by Niall Post: Hadam3p_eu_qgp9_2004 (d/l last night), a5qm_2013 and a5qc_2013 (d/l this morning) running normally, so far. WU a5qk_2013 ready to start when a core becomes available. Looks like a patchy glitch. HTH |

Error report hadam3p_eu
(Message 48428)
Posted 18 Mar 2014 by Niall Post: Thanks people. OK, if I am reading you correctly, I need to a) Go into Computing Preferences and change the "Suspend work if CPU usage is above" field value from 25% (default) to 0% (no restriction) (done) and b) Upgrade BOINC to the latest available edition (done). The rest is a bug in the 1997 WUs. Yes? |

Error report hadam3p_eu
(Message 48425)
Posted 18 Mar 2014 by Niall Post: Okay. I have now had the same problem with WUs hadam3p_eu_c10i_1997_1_008565387_0 hadam3p_eu_c10m_1997_1_008565391_0 hadam3p_eu_c10q_1997_1_008565395_0 The event log also says: "Task hadam3p_eu_c10q_1997_1_008565395_0 exited with zero status but no 'finished' file. If this happens repeatedly you may need to reset the project." Fine. This has now happened repeatedly. That said, I am 90-odd hours in and 44 hours from completing another hadam3p_eu WU. Will resetting the project reset this WU? Am I advised to wait until this WU ends before resetting the project? |
