2) Message boards : Number crunching : How normal is it for work units to abort? (Message 40380) Posted 18 Aug 2010 by old_user46232 Post: I came back to climateprediction about two month or so back, after a long leave and naturally also ran into this errors. I quickly found out that this is normal. What I don't really understand about this though is that if "INVALID THETA" or "NEGATIVE PRESSURE" are problems with the model, I would expect them to fail at the same point and therefore approximately the same credit claimed on all machines. I noticed however that the point where the models fail with this message vary widely and even complete for some persons. Can anyone of you explain that to me?

I don't care about the credits, but if the results are lost in the database the computingtime would be better spend on a new WU.
4) Questions and Answers : Unix/Linux : missing tickles (Message 14110) Posted 5 Jul 2005 by old_user46232 Post: I have a strange Problem with one of my machines. It is computing without problems on the WU "2uwm_400154712". But in my profile for this host there are no trickles whatsoever for this hostid from the time it started on this WU. Additionaly the name of this WU doesn't even exist in the profile. The WU my machine is supposedly working on according to thew profile exists as a zip file, but never got extracted. I'm at the end of phase 2 now and I have no file called trickle_up*.xml. The hostid is 97304
