Hi Mo,

Thanks for the research, but I never doubted that the problems involved my computer.

I\'m sorry if people are taking my comments personally.

From the early days of SETI@home, my understanding was that these were programs that could use my computers\' idle periods, with negligible human input. I am definitely not a \"suitable committed member\" willing to manually do checkpoints & restarts and shield the program from other tasks. As I said, I have retreated to the other BOINC projects with their Load/Launch/Leave paradigm.

Best wishes,
Rick

Rick, on looking at your results I find that 3 of your past/crashed models show -161 errors. These probably happened because of some incident/event on your computer. Have you tried to identify from Mike\'s top post in this thread what the problem(s) may have been?

4 of your past models, including the one that\'s just gone down, crashed with -107 codes. This usually indicates a graphics problem, momentary or longstanding, on your computer. Have you gone to the link Mike provides in his second post up above? Have you, as Thyme Lawn explains in the link, updated your graphics card driver (free download from the web a bit like Windows updates)?

We advise everyone to back up their climate models. The models take upwards of 4 months to complete (up to a year on my computer), running 24/7. It is fairly likely that something will go wrong on the computer during such a long period. So these long workunits/simulations are only suitable for committed members willing to make regular backups.

Tobie: Excellent, hope it continues to run :-)

Rick: Have you tried Prime95\'s torture test for a day or so? This will let you confirm that the hardware is OK under stress. The model is pretty much the most stressful software the PC will ever run.


Hi Mike,
Thanks for the suggestion. I waited for CPDN to, uh, disappoint again (got to 6% this time) then downloaded & ran Prime95. 53 hours, no problems.

Whatever is going on here, it just passed my time budget for tending to a screensaver.

Good luck with the climate prediction for those who remain. I\'m off to other BOINC projects.

Perhaps you should send a copy of your complaints to the UK Met office.
After all, it IS their code, and they run it daily on their supercomputers for weather and climate forecasting. So the sooner they know how terrible it is the better.



Hi Les,

Fine. Let\'s assume then that the core prediction sw runs perfectly on their supercomputers. That doesn\'t change a word of my points, it only indicates that the problem is elsewhere, for example in the Windows wrapper or the screensaver functionality. I\'m assuming that the UK Met does not run this daily on their supercomputers as a Windows screensaver.

Hmmmmf.

I just crashed a BBC sim AGAIN. I\'ve read the posts about backups and temperatures and so on, but I think that\'s all missing the point--

this software is very fragile.

That is not a compliment.

There are many applications that make my machine (AMD 3700+, 3GB ram) work much harder. It has never failed any app due to heat.

I\'ve had four or five sims get up to around 10% and die of something or other. I don\'t have time to babysit my screensaver. It\'s frustrating that this app, alone of all the BOINC apps I\'ve tried, is so prone to crashing.

Further, I really don\'t subscribe to the \"some programs crash, you know\" proposition. If I had paid for sw that behaved like this, I\'d be furious. Honestly, wouldn\'t you?

I would like to help CPDN and BBC et al. save the world from climate change. Seriously. However, if my sims all die, my machine might just as well be folding proteins or tracking mosquitoes or evesdropping on ET or something.

My preferred solution is robust code from CPDN. My interim solution will be to drop this project after the next crash.

Harrumph.
-Rick
