Hello all, I am trying to move my workflow on gridpp, but the problem is, I am a newbie! Andrew Lahiff has been very helpful in giving me good advice along the way - thanks. I hope you too could help me with this. I set up code, software environment, and data, and it works fine locally on Ganga. To move things on the grid, I put code & environment on cvmfs (thanks Catalin Condurache), and uploaded data on DFC. After submission, I got the error attached below. It looks like the job could not see the input data, and also some output sandbox was not properly initialised. My submission scripts looks like the example in the userguide. I suspect I might be doing something wrong perhaps here? j.inputfiles = [ DiracFile('LFN:/gridpp/user/giuseppe.congedo/my_folder/my_file'), Please note that the job fails no matter if I set DiracLFNBase or not in .gangarc. I look forward to hearing from you, and thanks so much for your help.
