Message 50418 - Posted: 8 Oct 2014, 20:57:58 UTC - in response to Message 50412.  

Mike

That's not the error log, just a BOINC log.
The real error log is called Stderr, and is found on the page for each individual model. Click the + (plus) to expand the list.

What you posted is:
1) A list of the files that BOINC couldn't find when the model crashed. And that's because the model didn't run for long enough to reach a zip creation point.

2) An indication that you're still using the default setting for one of the options. OK for other projects, often fatal here. Climate models do NOT like being constantly interrupted. As has been said zillions of times.

Finally, please read the thread here about the problems with the latest batch of PNW models, especially the first post in the thread.

Is there more information useful to you in the Error Log you mentioned in your last post? In any event the following stuff from Event Log is clearly not good. I've done 'reset project' many times - it makes no difference to the WU processing. I've had this type of WU failure for the past 2 weeks at least.
What should I do now Les

You could try changing the setting for Suspend work if CPU usage is above to zero.

But also, leaving the models alone may work. That message doesn't indicate a fatal error is imminent, whereas a project reset is ALWAYS fatal for running models, because that's what it's supposed to do.

And we can see the stderr list for your models, so there's no need to post them.

Another thing to check: Leave tasks in memory while suspended?

This is best set for Yes for this project.

I must have an old version of BOINC - this option not in Tools / Computing Preferences?

It has been there for a long time just realised that the format is slightly different. under the computing allowed section
underneath only after computer idle for Mins.
You will see, "While computer usage is less than .... percent (0 means no restriction.)

Setting this to 0 for some people reduces the incidence of the messages you posted.

The options are also in the Computing Preferences section on your Account page on the project's server.

You have to use either the web-based preferences set through this web site, or local preferences set locally via BOINC Manager. You can't mix the two.

If you set even one value locally via BOINC Manager, the whole set is 'frozen in' and web-based preferences are ignored from that point on.

You said "That message doesn't indicate a fatal error is imminent, whereas a project reset is ALWAYS fatal for running models, because that's what it's supposed to do."

Les,
Does this mean that I should not have done a 'Project Reset"? (I did it after 'suspending' the failing WU). Is there something else I should do now that I have done a "Project Reset" e.g. reload the Climate Change programs?

Probably not an issue. You said that models were failing anyway.

When you get the occasional message of the type

9/10/2014 12:07:24 PM | climateprediction.net | Task hadcm3s_32ih_2003_2_009079324_1 exited with zero status but no 'finished' file

it isn't a problem but a long stream of them almost inevitably means the task ends up failing.

Main thing to do is check the settings in computing preferences and then see if that resolves the issue.

Other than making the settings more cpdn friendly, I don't think there is much else you could have done.
