1) Questions and Answers : Windows : Two more models behaving strangely (Message 41498) Posted 17 Jan 2011 by RichardRodd Post: Well the bizarre thing is that it only shows a Blue World SOMETIMES - usually when the Time to Complete zooms upwards. Right now TTC is running at 846 hours (Completed is 1018, 51%), but when TTC next sits at approx 1300 hours (% complete ~35%) the temperature (default?) graphics will then show a Blue World - I've not checked all graphic modes in that state - to be honest I can't remember how to! So if you care to tell me how to check, I'll let you know next time it glitches. In the meantime, the other model (12453603) just struggles onwards ... Cheers - Richard
2) Questions and Answers : Windows : Two more models behaving strangely (Message 41491) Posted 17 Jan 2011 by RichardRodd Post: 12018622 a HadCM3 Coupled Model Experiment Optimised File I/O v6.04 - has been running for ever. I's progress and completion numbers fluctuate wildly and sometimes the graphics show a Blue World. At any particular level, Time To Complete seems to rise gently.. Weird. On the other CPU I have 12453603 which may be suffering as a consequence and just seems to hover at 98 hours to completion without going anywhere. Any ideas? I have stoppped and retarted BOINC as well as rebooted the m/c a number of times. Thanks for any help -- Richard
3) Questions and Answers : Windows : HADAM3P Model stuck (Message 41400) Posted 31 Dec 2010 by RichardRodd Post: Worked a treat - nothing like flushing out the old buffers!!
4) Questions and Answers : Windows : HADAM3P Model stuck (Message 41388) Posted 30 Dec 2010 by RichardRodd Post: Hi, Can anyone advise me whether these models can descend into Ice Worlds, and thereby merit aborting? I'm running hadam3p_eu_w2q6_1989_1_006770086_1, Task 12314662, work unit 6973402. It's been hung at 99+% for a few days (not sure how long to be honest) and now I see the estimate to completion is slowly rising, while the data (http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=12314662) seems to suggest the temperatures are falling... Advice please? Many thanks - Richard
5) Message boards : Number crunching : Iceworlds & Slowdowns hadsm3/mh - Closed - Discussion (Message 36509) Posted 27 Mar 2009 by RichardRodd Post: Greetings, again. Further to the post just above, I suspended those two tasks, and the waiting task that started up is behaving the same... a rising to-completion number from the outset. Can someone help me fathom this out? Might it be because this m/c is running with quite a full hard drive - 10Gb free out of 70. This is a 2-cpu m/c and BOINC hasn\'t downloaded a second task to me. I found a BOINC discussion thread (http://einstein.phys.uwm.edu/forum_thread.php?id=6389) that suggested BOINC knows this m/c is struggling, but I\'m not sure how to go about trouble-shooting... Oh, I also upgraded from 6.4.5 to 6.4.7, so it should be a clean installation here. All help gratefully received - as ever! Many thanks - Richard
6) Message boards : Number crunching : Iceworlds & Slowdowns hadsm3/mh - Closed - Discussion (Message 36507) Posted 27 Mar 2009 by RichardRodd Post: Greetings. I\'ve just spotted a couple of very slow-running models. I should probably abort - can someone please advise... 1. http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=7673807 Current timestep = 49417 of 259248 s/TS = 56.6 2. http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=7731951 Current timestep = 39775 of 259248 s/TS = 3.64 Neither are blue / ice worlds, but the to-completion time is rising, so maybe they\'re turning blue... It\'s an Intel machine runnig WinXP, not overclocked and has, prior to these two models, turned in a few complete runs. Thanks - Richard
7) Message boards : Number crunching : A blue world for aborting...? (Message 36258) Posted 28 Feb 2009 by RichardRodd Post: Thanks everyone for all those comments and suggestions. I\'ll start on the task list suggested and keep you posted, but it\'s a \'remote\' m/c, so it\'ll take a week or three... Bye for now.
8) Message boards : Number crunching : A blue world for aborting...? (Message 36248) Posted 28 Feb 2009 by RichardRodd Post: Greetings all. I\'m posting back here after a week or three to ask for more advice, but I don\'t want to go over the top with this...! I\'m wondering if the problem I reported above may well be this particular machine - the \'elderly\' Packard Bell. Each work unit loaded and run here seems to rapidly turn into a Blue World. I have uninstalled and reinstalled BOINC (now at Ver 6.4.5) but it seems to have made no difference. I\'ve had a look at how the current task 6191307 is running elsewhere. The three users with the highest credit are still in Phase 1 with no reported precipitation. I now understand this is a warning sign mentioned above for a Blue World, but I\'m not sure at what stage: the last note above suggests at stage-end - which implies I should keep the faith until end of Stage 1. Anyway, the s/TS of these other users are reasonable and or steady, mine is already 8.33 and rising. But that might have something to do with the computer\'s general use - I don\'t know? So here\'s my question. Is this actually indicative of (another) Blue World - so do I abort and try again? Or is this telling me I have a m/c that can\'t hack it?! Some of the posts above suggested the latter... This model is running steadily (after a fashion!) but at 74 CPU hours and 4% complete something is clearly not happy - and, as you\'d expect, the \'To completion\' figure just rises steadily, if imperceptably - now on 650 hours. On better behaved, albeit more powerful, members of my little \'family\' I expect to complete a model in some 400-500 hours, and do. When I look at the m/c it seems unremarkable - XP (Home edition, admittedly) SP3. A few years old, a chip that\'s neither fast nor slow. BIOS...do we really care? I put 2Gb RAM in it, so it\'s not that. Plenty of space on the hard drive. No interference from other apps. Any ideas anyone? Many thanks as always - Richard
9) Message boards : Number crunching : A blue world for aborting...? (Message 36028) Posted 26 Jan 2009 by RichardRodd Post: Hi there mo.v and thanks for your comprehensive advice. When I hit my first ice world a couple of years ago, the advice then was just let it run because it will run to completion: I think I had a couple back then ... and they did, but only after some 1000+ cpu hours! The tasks you suggest I abort are both only running with a S/TS less than 6 (how high that number was used to be a factor in advising whether or not to abort, I recall), and one has only approx 100 hours to go (the other 300). It seems a shame to kill them at this late stage IF IF IF ice world results DO contribute useful information, as was implied to me the first time around. But I gather from your penultimate paragraph that wisdom has moved on and they\'re now considered of no value. I\'d appreciate your final view on that... Anyhow, the task that sparked this thread was the first one on a new computer I\'ve just added to my \'family\'. But it\'s an ancient Packard Bell, so may not be up to the task, even though the raw spec suggested it\'d be okay - a 2.66GHz chip with 2GB RAM, not used for anything other than basic MS Office stuff - no hungry graphics games! So I\'ve got the next task running and will watch progress with interest. Once again, many thanks for you interest. Kind regards Richard

I\'ll watch the progress of the next one with interest to see if there\'s some other problem there as you suspect. After which probably a BOINC reinstall... sigh! All the best. Richard
