rescale to data range option for generated co-processing scripts doesn't work in parallel
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When generating co-processing scripts with the GUI plugin there is an option to auto-rescale to data range for outputting screenshots. This doesn't work in parallel because when running batch in symmetric mode each process only gets its local range. We need to do an allreduce to get the global value.
