sigh, basically annoying but I'm not sure if there's anything anyone can do about this due to the way windows operates.

I run various BOINC projects, among them is the climatepredictation.net . Now climateprediction as many know has really large workunits, the kind that take hundreds of hours to process and travel back to the server with trickle updates. Unfortunately because the length of time is so long to process these, it's really unfortunate when something occurs to disrupt it, basically negating the data.

So what's happening is so silly it makes me angry. Unlike a lot of BOINCers, I turn my computer off from time to time, generally when I'm away for awhile. Now windows during a shutdown always acts the same way; it tries to close down each program and gets confused when something's preventing it from turning off. One such thing is a program such as microsoft word or even notepad asking "Do you want to save your work?". No problem with that, most users close out of the screen, save (or discard) and then try again. Unfortunately when BOINC is set in always run mode.... this point where windows is hung with the dialog box..... results in computational errors with the tasks that try to run. BOINC will keep trying to work on them, and when it can't... will throw up it's hands and give up completely on the workunit. What's especially annoying is that this occurs within about 1 or 2 minutes... without much time for the user to react and fix the problem.

Taking a look at my host page: http://climateapps2.oerc.ox.ac.uk/cpdnboinc/results.php?hostid=1112451 You can see the 3 climateprediction.net tasks from February 24 that are showing ERROR WHILE COMPUTING. These are all because of the windows shutdown situation mentioned above. Each task had approximately 17-20 hours processed already. Gone. all gone.

Really annoying. I'll post this to CPDN's board too...

The work around is to shut down Boinc before you shut down Windows, then the CPDN task is exited in a controlled manner.

I am having a similar problem but under Linux ubuntu 11.10 with SETI@home.

Suspending 'Astropluse v505' applications and shutting down for a reboot renders the status with an 'error while computing' message. This has happened 5 or 6 times -- all terminating with the above error message. Some of these happened with only a suspend request -- rendering the computation irretrievable, with an 'error while computing' message.

I have only just signed on here during the past week or so and am still working my way through this program, but I have only had problems with the larger 'Astropulse' files and have no clue why this problem is repeating while the others work to completion.
