This is the main Model listing.
While a model job is running, each MPI process will write is output in a separate file, so while a simulation is running you will only see the first part of the output in the listing. Close to the end you will find a line starting with:
INFO: temporary listings for all members in directory
Under that directory you will find all the temporary process listings there is one sub-directory for each process with a file inside starting with 'stout*', the number of the main process is '00000'. Once a job finished all process listings will get added to the main model listing. However, in case the model crashes it might not always be able to collect all of them. So in case of a crash you might have to look at these listings as well if you want to find out what happened.
If you want to see the simulation advancing while it is running, you can execute the command 'u.tail' on the main model listing. It will do a 'tail -f' on the listing of the main MPI process for example:
