3.5 Running the model in prognostic mode

If compilation finished succesfully (section 3.4) then an executable called mitgcmuv will now exist in the local directory.

To run the model as a single process (ie. not in parallel) simply type:

% ./mitgcmuv
The ``./'' is a safe-guard to make sure you use the local executable in case you have others that exist in your path (surely odd if you do!). The above command will spew out many lines of text output to your screen. This output contains details such as parameter values as well as diagnostics such as mean Kinetic energy, largest CFL number, etc. It is worth keeping this text output with the binary output so we normally re-direct the stdout stream as follows:
% ./mitgcmuv > output.txt
In the event that the model encounters an error and stops, it is very helpful to include the last few line of this output.txt file along with the (stderr) error message within any bug reports.

For the example experiments in verification, an example of the output is kept in results/output.txt for comparison. You can compare your output.txt with the corresponding one for that experiment to check that the set-up works.
