After the runtest.sh script executes the coupled simulation it carries out a check of output and extracts timing information to determine time to solution. The output check compares the daily global mean atmospheric zonal flow with a previously stored set of values for this configuration. The previoulsy computed set of values are in the file atm.1/stdout.ref under the JMC Code L Improvement 1 top-level directory. These stored values are checked against the time series of mean flow written to the file atm.1/STDOUT.0000 in the script runtest.pbs. Time to solution information is also extracted by runtest.pbs. The compute time for the 16 processor, 10-day simulation used for the Code L Improvement 1 is converted into a measure of the time required for one year of simulation. This is printed in the summary output file stdout.pbs.
