Hi Steve

It looks as if you have two nice computers. Here they are:

http://climateapps2.oerc.ox.ac.uk/cpdnboinc/hosts_user.php?userid=18823

But as you say, they've been crashing quite a few tasks and #1 in that list has been having more of a struggle. Here are its tasks:

http://climateapps2.oerc.ox.ac.uk/cpdnboinc/results.php?hostid=1307835

We can click on any of the task numbers and then see the details of the task by clicking on Stderr+. The messages that then appear and (sometimes) the error code (or exit status) often provide useful clues as to what happened.

* The tasks (models) that say Download error are almost certainly due to some problem inherent in the models eg a missing file. Don't worry about them.

* A small number of the crash messages show 5 or 6 times that there was an INITTIME error. This is something wrong with the model which tries to restart 5 times and is programmed to crash on the 6th attempt. Don't worry about these.

* A few of your models crashed with code 25. This can be caused by a bluescreen crash. Is this ever a problem on this computer?

* Sometimes two or three models seem to have crashed at the same time. I'm guessing that because they reported to the Oxford server at the same time. Something the models didn't like must have happened. One possible cause is that you turn off the computer without completely exiting from BOINC first. Before shutting down the computer you should:

- open BOINC Manager
- in the Activity tab stop computation. I also stop network access.
- in the File tab click on Exit

Don't just close BOINC Manager before shutting down the computer; that doesn't work because the models will still be crunching.

* It's safer not to let your antivirus program scan BOINC and the models while they're running. Either exit from BOINC before scans or exclude BOINC from scans.

Other members may well have extra suggestions.

Cpdn news

This is a well known issue. You were hit by the decadal crash problem. The 40 year WU�s, when they reach the end of a decade (at 25%, 50%, 75% and 100%), pause the computation to create a zip file. Far to many models crash at this point.

The only thing you can do to help prevent this is not to interrupt the model when it is at this point. Don�t suspend it of shut it down when it is creating the zip files. Some will crash anyway.

The only thing I would add is suspend computation before doing anything very processor intensive such as video editing. I know the theory is that BOINC should handle things without problems but my experience is that id doesn't always and a couple of times when a large file has been going through the render process and I have forgotten to suspend computation by BOINC it has crashed models.

Steve

You also have another problem, as per the current latest post in News and Announcements.

You have 2 models that fit this description. Continuing with them is a waste of electricity.

**********

Another thing that may cause a crash, due to model interruption at a critical moment, is leaving the option: Suspend work if CPU usage is above set to the default, or to anything else that constantly interrupts BOINC and it's tasks if the cpu load load gets above that %.
