Exit code 22 is one of the more common crash codes with CPDN models on Windows computers. We think this exit code comes from the model, but BOINC thinks it\'s a Windows error and generates this \'The device does not recognise the command\' message that would be true if it were a Windows error. But as far as we know, it isn\'t.

Carl, who used to be CPDN\'s chief programmer, doesn\'t know what it means.

It doesn\'t mean the model\'s defective. Other Windows computers will, typically, complete tasks from the same workunit. These HadAM3P models are turning out to be pretty stable.

All we know is that something\'s gone wrong.

In the README collection about Crashes & Problems, look at item #6 by MikeMars who explains everything he could think of that we should and shouldn\'t do when running climate models.

I see you\'re running 4 HadAM3P models on this quad. We don\'t advise running HadAM3Ps simultaneously on every core. Before you download your next model, go to the ClimatePrediction section of your account and select a different model type. Or suspend one or two of them and run tasks from other projects on one or two cores. Please see my post of 5 March in the forum News thread (link in my signature).

Exit code 22. Either filesystem/permissions problems, or Windows Vista security doing something bad. It doesn\'t appear you\'re overclocking.... How are your CPU temperatures with 4 cores busy? The moderators will have more suggestions, I\'m sure.

The very first HADAM3P task that I tried to run crashed. Any ideas why? Other tasks run OK.
