after a system crash the current sulphur cycle was aborted
no error message
boinc showed the sulphur workunit as \"finished and uploaded\".
I still have the data on HD but is there a way to recover the work? 80h done so far
Boinc has downloaded another workunit and has begun crunching it.

You can restart a crashed model from a backup of the BOINC folder made before the crash. Otherwise it\'s gone for good.

Your model failed with: exit code -1073741502
This is a graphics related problem, somtimes fixed by updating the driver for your graphics card from the card maker\'s web site.
It can also be caused by a conflict with another program that uses graphics: games, things like Excel, video viewing/editing, tv cards, etc.

Your new Coupled Ocean model will also fail soon, because it needs a BOINC version 5.*; the latest is 5.2.13, available from the link on the download page.
