Warning: Failed and aborted models can take up disk space
(Message 48316)

Post: Well,I am no hardware expert so don't know how to measure the wear on my Crucial SSD but I do know I have been running BOINC on it since October 2010. It had a capacity of just over 64GB then and still has the same now and I have noticed no deterioration in its performance. It has no bad sectors which is not the case for the main mechanical drive on this computer. Crucial sell these as replacements for the C: drive and claim their average time to failure is greater than that for a mechanical drive. I have no reason to doubt this and I am considering purchasing a much bigger one in the near future. |

Post: I am sure I have mentioned this before but can't find the previous thread; maybe it was on the other forum? Anyway it is worth warning again about failed or aborted models not always deleting themselves from your hard drive. I run BOINC on my C:\ SSD to save continuous running of my other hard drives and also because the models run a little quicker. It is only 64GB in size and more than half of that is used by the Windows 7 OS and other essential files. I have just noticed that BOINC was reporting it couldn't run one of the new models because there wasn't enough disk space. Looking in the Program data -> BOINC -> projects -> ClimatePrediction.net folder there were several folders and zip files with with old modified dates and several zip files all starting with 'hadam' or 'hadcm'. None of the names referred to models currently running so I have recycled them and released over 3GB of space. Some of these are probably failed or aborted models affected by the many power cuts we have had this winter. |

Post: Finally some new models!! I have received only one, presumably returned, model in the last 4 months and now I have just noticed 9 downloaded in the last 3 days, 5 of which are these new ones. No flooding here on the English Welsh border and only one bad gale which destroyed our poly-tunnel skin but it was nearly due for replacement anyway. What I have found unusual is that we have had only three frosty nights all winter and two of those were last night and tonight. We still have two roses flowering from last year; that is unprecedented in the 40 years we have been here. |

Uploads Fail
(Message 41377)
Posted 29 Dec 2010 by JohnofWem
Post: Is there a time-out on the zips waiting to upload? I currently have 20 waiting in the transfers tab since the 25th. I was crunching alternative projects on WCG, Drug Discovery and Virtual Prairie but these have run out of work so I would prefer to carry on with CPDN models. I have 5 which have been running for some time and 3 new ones have downloaded recently and don't mind the zips sitting there provided I know they will eventually be uploaded, no matter how long this takes. Far better to heat my office using the spare heat from the computer as it crunches away rather than turning on an electric heater ;=) |

Post: Hi, John, Interesting question. I have the figures for the total load on the computer then and now Last Winter with 200gB and 120gB PATA drives Idling : 160w Boinc only : 163w One model : 209w Two models : 220w This Winter with 2 250gb SATA drives Idling : 155w Boinc only : 157w One model : 203w Two models : 213w Unplugging the LCD reduces the load to 183w Switching off the LCD, with the 12V adapter still attached to the mains, reduces the load to 188w. Now the interesting one. The second drive is used mainly for backups of my software so I have it set to power down when not in use. BOINC runs in the 5th partition on the first drive and I back it up daily to the second drive. Backing up last winter (not BOINC - this was still running) the load increased to 232w. Backihg up this winter the load increased to 217w Everything else is exactly the same. The motherboard can support both PATA and SATA drives. So overall the load is 5-7w less with the new setup running the models on the SATA which it 25% bigger and 15w less when running the second drive which is 100% bigger. That second drive was about 5 years old. I am being more diligent remembering to unplug rather than just switch off the LCD monitor so overall I could be saving around 5-10watts. Not really enough to explain the heat difference. I can only conclude that this winter is already turning out to be colder than last. The last few days have been around 6°C during the day and -2°C at night. The office is very small, about 4 feet by 5 and in a converted cloakroom near to an outside door which is not very draught proof. We are having a better door fitted early next year. I will see what difference that makes. |

Post: Like last winter I am now using my computer in the dual role of crunching two models and as an office heater. My RAC has again climbed above 500. :D Last winter I only needed extra heating for one day. This winter, thanks to the present cold snap I have already had to switch on extra heating for two days. This could be because I am using SATA drives rather the PATA drives I had last winter? |

Post: Thanks mo.v, I must have missed this one. There are so many forums to check for news!! The slow down does seem to be about 20% so I am still on course to reach my 500RAC winter target (using the computer 24hours a day as an office heater!!) |

Posted 4 Nov 2007 by JohnofWem
Post: I downloaded a new 80 year model 5.44 a few days ago to run with an existing 160 year model 5.15 on the other core. When it started running it reported an s/TS of 3.9 rather than the 2.5 the other one is doing and this has been the norm for all 6 previous 160 year models. At first I thought maybe it needed to settle down but after 75 hours running it still has this very high s/TS. Comparing with the other model it is tricklng every 29 hours rather than 24 so it is definitely running a lot slower. This model calls itself \'optimised file i/o\' which to me means it should, if anything, be running faster, accessing the drive less often. Task manager reports it is giving the same amount of time to each model so this can\'t be the cause. I am running BOINC on an almost empty NTFS partition on a large buffered SATA drive which I regularly defrag. I also have 2GB of memory which most of the time is mainly unused. You would think these would be ideal conditions to run these models. Do these models do the same amount of work? They seem to be doing the same number of calculations each simulated day. |

Post: Just counted the trickles. There were 37 (!!) of them before it finally suspended itself and a new model downloaded. Not to worry, I will leave it for a few days and then activate it again to see what happens |

Post: I have a slab model at 99.999% which early this morning showed this over and over again for several minutes 01/11/07 10:33:29|climateprediction.net|Sending scheduler request: To send trickle-up message 01/11/07 10:33:29|climateprediction.net|(not requesting new work or reporting completed tasks) 01/11/07 10:33:34|climateprediction.net|Scheduler RPC succeeded [server version 509] This appears to say its last trickle succeeded but obviously it didn\'t as it is still stuck at 2 minutes to go. Eventually after about 3 pages of these messages it went to \'waiting to run\' and downloaded a new 80 year model which is running OK together with an earlier 160 year model. Neither will have a decadal upload for several days. Is this the same cause as reported here and in the top sticky or is something else going wrong here? |

Post: Here\'s a live link where the problem is obvious Hmm. Looks like a misinterpretation of the unicode characters between the Windows fonts and international universal fonts. There is often more than one way of getting the same symbol even in the same font set. They look the same to the viewer but the underlying string of bytes representing the characters is different and often, as in this case, there are two bytes for a single non-Latin character, the first byte indicating where to start counting in the table of more than 256 characters. All standard ASCII characters are numbered between 32 and 127 with extended ones up to 255. Some of these extended ones are accented letters but these could be repeated later in the table, often more than once if they are used in different language sets; this is probably where the problem arises. I have had this problem, especially with German characters but I get round it by always using the same method for any string input output or matches and ensuring that Windows is always using the same international settings and fonts for a particular country-based database. Obviously you can\'t do this here as you don\'t know what international setting is used for the string matching or the string input/output. The real problem is that Microsoft is American English based at its core. For British users this only means spelling some words like colour and programme differently but for languages with accented or even different characters this can be much worse. Sorry if this isn\'t much help but it may at least explain the problemThis might help or try googling unicode for more information. |
