The models seem much more stable under Windows 7 than they did using Vista. When I was using Vista I hardly ever got through a model with it crashing and being restored at least once. The only thing that saved me was lots of backups. Since installing Windows 7 I have had hardly a crash. The computer hardware hasnÃ¢â‚¬â„¢t changed. This increased stability seems to hold true regardless of the type of WU. While most of the models that I have benn running have been HadAM3pÃ¢â‚¬â„¢s, I also finished a HadCM3 and a HadSMmh. Both seemed more stable. Has anyone else noticed this? I also wonder if Intel chips running HadSMÃ¢â‚¬â„¢s on Windows 7 are less likely to produce ice worlds???? ID: 37398 · Reply Quote

I have run several models on My Vista Computer and havent had any unstability issues. I think I had one ice world but thats about it. Rick ID: 37399 · Reply Quote

On Windows 2000, XP and Vista I've had very few unexplained crashes - but lots of iceworlds. I'm running exclusively HADSM3MH at the moment to try to catch iceworlds in an attempt to find the cause (in which effort there is some progress). My impression is that the HADSM3MH models have entered a slightly more benign region of parameter space, as my iceworld production line is producing nothing but finishers. Grrrr. There are reproducible differences in iceworld behaviour across Intel chips, but none that I've found across Windows versions. That may, of course, change with Windows 7 ... A good test would be to restore a backup of a model that crashed previously and check whether it also crashes in Windows 7. PS If anyone wants to help find the cause of iceworlds then send me the '.cpdn' file just before the freeze, from a graphics recording. You don't have to watch the graphics or leave them running! The file is easy to spot, as it's the last normal-sized file before they start shrinking. For example: [size=10]19/06/2009 18:45 123,830 hadsm3fub_jslu_005955205.0026989.cpdn 19/06/2009 18:46 123,576 hadsm3fub_jslu_005955205.0026990.cpdn [color=red]<== this one, please[/color] 19/06/2009 18:46 89,026 hadsm3fub_jslu_005955205.0026991.cpdn 19/06/2009 18:46 7,785 hadsm3fub_jslu_005955205.0026992.cpdn 19/06/2009 18:46 7,786 hadsm3fub_jslu_005955205.0026993.cpdn[/size] The files are stored in something like '...BOINC\\projects\\climateprediction.net\\hadsm3mh_kx0m_006032058\\tmp'.
