Create a new case b1850.basics with the command:

cd /glade/u/home/$USER/code/my_cesm_code/cime/scripts
./create_newcase --case /glade/u/home/$USER/cases/b1850.basics --res f19_g17 --compset B1850

Case setup:

cd /glade/u/home/$USER/cases/b1850.basics 
./case.setup

Do not make any other changes since we are running an out-of-the-box simulation.

Build and submit:

qcmd -- ./case.build
./case.submit

Remember that qcmd is used on derecho only.

Check the status:

qstat -u $USER
