Two Tickles
(Message 18949)
Posted 3 Jan 2006 by  Honza
Post: No all \"Reason: To send trickle-up message\" are due to sending trickles. I remember some models sending trickle even when not needed - but I believe this is due to wrong BOINC interpretation of connecting CPDN server. I would not bother with it as far as model is doing fine and real trickles are listed on server on WU result page. |

Zip files
(Message 18925)
Posted 2 Jan 2006 by Honza
Post: Actually, a completed sulphur model is zipped down to a little less than 1 GB at the end, but it can get up to 2.5 GB right before that.Correct, @ Ray and others: you may try to re-RAR the completed model package. Slab went down from 340MB Zip files to 288MB RAR (best compression) so 85% of the original. Sulphur use gZIP compression and went down from 1000MB gz to 882 MB RAR. Still will not fit to a single CD...but one may put 5 re-RARed SC models to a DVD-R instead of 4 original ZIPped. |

Post: It is in my climate folder and is titled sulphur_data 4.22 windows_intelx86.zip. It includes jobs and datain\\anci\\ctidata\\datasets. Hope this is of some use.This is a part of CPDN application, which is used with every Sulphur cycle model (WU). It is not generated during error nor model post-processing, but downloaded with the rest of the application package (sulphur_um_4.22_windows_intelx86.zip and sulphur_se_4.22_windows_intelx86.zip with some .exe files inside). Basically, you need to keep all files in \\climateprediction.net. Files in subfolder of \\climateprediction.net are dedicated to each of CPDN WU and those can be backuped/deleted after particular WU is completed. This leads me to a \'backup issue\' which has been already discussed, for example here: http://www.climateprediction.net/board/viewtopic.php?t=2361 Hope it help. |

Post: Once WU is uploaded, you can backup/delete it\'s folder ( \\ sulphur_46vb_000295799_1 in this case). You have another 3 WUs errored out just at the beginning...something now good is happening with your machine. |

Database Sluggish -- Moved Trickle Info \'Down\'
(Message 18794)
Posted 28 Dec 2005 by Honza
Post: Perhaps a script of some kind can be added so as to update credit displays (from Trickles) every, say, 8 hours, so as to better handle the server load.As I understand, millions of trickles are to \'blame\' databse sluggish so recounting them several times a day is not an option (for the moment). RAC never did good job for CPDN... |

slab / sulphur models, and where we are heading
(Message 18791)
Posted 28 Dec 2005 by Honza
Post: Time goes different in Oxford so it\'s not 2 years of Earth time :-)...the big future forecast runs (the 1920 to 2080 hindcast/forecast runs that will be the \"grand finale\" of CPDN over the next year or two). Atmospheric models, High resolution models, regional forecast...there is still plenty to go. And, as Carl sayd, \"we will regenerate workunits based on past results\". There will be re-runs, re-checkings. Carl, thanks for the update and keeping us informed. Many things got clear, some are still foggy to me (separated \'pool\', web etc.). |

Post: I see your point. Perhaps I\'m not as concerned with trickles (hence credit for some users). I do have only dual-cored machines. Mainly i monitor progress of each model in % - BoincView does very good job over LAN/multi-cpu/cored machines. I watch for final upload and model complete then - it is the case where i dig into the model: final graph etc. There is still a chance that Carl/Tolu will optimize db so that this feature will be ther again. |

Boinc on Dual Boot Machine
(Message 18540)
Posted 21 Dec 2005 by Honza
Post: Hi there, BOINC does not allow having a separate folder/partition for data; all goes in one folder and it\'s subfolders. Even when you edit appropriate .xml files etc, new WU will go to the default folder. I suggest to simply put BOINC folder to a place where both OSes have access. |

Post: The main account page does not show any trickle information anymore (since Dec. 20th). It is very complicated now to check which computer reported a trickle.Martin, see the other 2 or 3 threads for Carl\'s explanation. You can still see when all of your computers last contacted server on a \"Your computers\" page. I think this option is quite easy to navigate. http://climateapps2.oucs.ox.ac.uk/cpdnboinc/hosts_user.php |

Post: codycowboy, please, look again - it\'s 30 Nov 2006, not 2005. 1115 hours might be right, but BOINC tends to overestimates time-to-complete of jobs. It will take couple of weeks to complete a CPDN model. |

Post: Agree with Les - CPDN is quite demanding and sensitive to HW overall stability. On the other hand, CPDN can be VERY stable - on one my machines, I have 33 completed models in a row (including Sulphur cycle) [ with only 2 failed during early alpha/beta stage last summer, which is not surpricing]. |

server state means ??
(Message 18283)
Posted 16 Dec 2005 by Honza
Post: Is there some kind of time-out that happens between trickles, or what?There is a 2-weeks time-out to the active machine count/status. The policy on re-sending inactive model, I assume, depends on the current needs of the project (e.g. when Sulphur cycle models are needed, Slab model will not be re-send when they error-out or become inactive). |

Post: Perhaps a simple fix like: when newer trickle arrives, put to state from \"over\" to \"In Progress\" again. This may propitiate people\'s curiosity and make it more consistent with the actual situation of individual model progress. Lookin at my results page, server status ain\'t no right. |

(Message 18271)
Posted 16 Dec 2005 by Honza
Post: CPDN is kind of different as of \"state\". Server will accept further trickles and even final upload - even after WU is beyond deadline. If you are doing regular backups and - for example - experience a power failure with model crash, you can revert to backup and continue your model. This is to enable participant to finish the whole model. In that perspective, I think, it does make more sense. |

Post: I have several postscript files with good images on but I\'m not sure how best to get them on to the discussion boards. Does anyone have any suggestions?I would make a PDF files from them (everyone can download and see/print in any resolution/zoom if they are really postscript/vector files and not bitmapped. Using them on a forum would need to make a .png (or .gif) files from postscript (an easy task for me) and upload them on a server with link to the forum post(s). If you need help with it, you can provide me with a link to download or send them to me via e-amil (prefer zipped as this should shrink zipe of postscripped files significantly). |
