Hi, folks.

10/12/2007 22:39:14|climateprediction.net|Computation for task hadsm3fub_0361_005911833_8 finished
10/12/2007 22:39:14|climateprediction.net|Output file hadsm3fub_0361_005911833_8_3.zip for task hadsm3fub_0361_005911833_8 absent

Does anyone know what has happened here, please? How can it be avoided in future? And can the unit be resurrected?

Cheers

It sounds a little like you may have done an Update shortly after the zip upload to get it to \"Report\".

If this message is received too early, the zip might still be on the Upload server, waiting to be transferred to the storage server. Hence the message (paraphased): \"What are you talking about? There\'s no final zip file here.\"

If you DIDN\'T click on Update, then I\'m not sure what happened.

As recovering the unit, the usual advice applys: Only by rerunning the last bit of the model from a backup made before the model finished.

This was the result being talked about:
http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6981207

I think it crashed just prior to the end? The last successful trickle was phase 3, 248,446 (very near the end but still a few hours to go).


And the error message was an exit code 3:
<core_client_version>5.10.28</core_client_version>

What was happening on the PC at 22:42 yesterday? Where is the model installed, on your PC\'s local hard disk, or on a network / removable disk / usb key / etc? )just guessing from the error message).


As Les says, if you have a recent backup, you could resume this model.

Thanks, Les & Mike.

At 22:42 I did do an Update, but the model had crashed by then. It had come up with a computation error message and a time error. The time to go had stuck at 3 seconds - so nearly there! However, it had been attempting to trickle up between 22:29 & 22:38 and then a new model started at 22:38. Could it be that BOINC started the new model because of a time error on the trickle up and then the crash occurred as a consequence of the 2 models overloading my PC?

BOINC/CPDN runs on my PC (Vista with dual-core 3800+).

I haven\'t been doing back-ups and the PC had been running for 6 days continuously.

The scheduler messages might indicate that it\'s something to do with networking? There is a bug in boinc which can cause crashes if the local network fails (i.e., when dialing in, or a firewall crash).

The second model would have started to download+run when the first crashed.
