Hi all, we lately had quite some problems running the VirVubFit, probably related to reading and writing from the scratch area. In many cases the jobs just were not able to read in this file: /u/ec/asarti/Unfol13b/VubAnalysis/datasec/csx-gen-New.root which is on scratch space if I am not mistaken. Resubmitting helped in all cases if done often enough. The reduced signal MC ntuples which we are using (those that have all events, not only those with Breco candiates) are on scratch space as well. I noticed yesterday that there seems to be another problem. The jobs do not seem to be able to read all events from those files: Error in <TTree::Write>: No file open, while reading the files. And I find different numbers of events in the output histos for different runs of the VirVubFit. At the moment so many events are left out (something like a factor of 0.5) that I do not feel comfortable using the results from the new files. What I have done so far does not seem to be affected, but doing other things like varying Lambdabar is not really possible with this. Could this also be related to the reading and writing issues on scratch space? Is there enough space on the AWG disk to move the reduced ntuples there? The two signal MC ones are 1.1G together. Cheers, Kerstin
