Modify the runtime settings in env_run.xml for a low-resolution, 48 hour forecast:

  • Reduce run length from 5 days to 48 hours
./xmlchange STOP_OPTION=nhours,STOP_N=48
  • Reduce wallclock time from 12 hours to 30 minutes
./xmlchange JOB_WALLCLOCK_TIME=00:30:00 
  • Turn off short term archiving 
./xmlchange DOUT_S=FALSE 
  • For the Tutorial, there is a reserved queue:
./xmlchange --force JOB_QUEUE=S4857724

Run the case: 

./case.submit 

See https://ufs-mrweather-app.readthedocs.io/en/ufs-v1.1.0/quickstart.html for  more information on this command. 

After running ./case.submit, you will see:
