This specifies all the steps necessary to create, set up, build, and run a case. The following assumes that $CCSMROOT is /user/ccsmroot.
Create a new case named EXAMPLE_CASE in the ~/cesm directory. Use an 1850 control compset at 1-degree resolution on yellowstone.
> cd /user/ccsmroot/scripts > ./create_newcase -case ~/cesm/EXAMPLE_CASE \ -compset B_1850_CN \ -res 0.9x1.25_gx1v6 \ -mach yellowstone
Go to the $
CASEROOT directory. Edit env_mach_pes.xml if a
different pe-layout is desired first. Then set up and build the
> cd ~/cesm/EXAMPLE_CASE > ./cesm_setup > ./EXAMPLE_CASE.build
Create a production test. Go to the test directory. Build the test first, then run the test and check the TestStatus (the first word should be PASS).
> cd ~/cesm/EXAMPLE_CASE > ./create_production_test > cd ../EXAMPLE_CASE_ERT > ./EXAMPLE_CASE_ERT.test_build > ./EXAMPLE_CASE_ERT.submit Wait for test to finish..... > cat TestStatus
Go back to the case directory, set the job to run 12 model months, use an editor to change the time limit in the run file to accommodate a 12-month run, and submit the job.
> cd ../EXAMPLE_CASE > xmlchange STOP_OPTION=nmonths > xmlchange STOP_N=12 > # use an editor to change EXAMPLE_CASE.run "#BSUB -W 4:00" to "#BSUB -W 6:00" > ./EXAMPLE_CASE.submit
Make sure the run succeeded. Look for the following line at the end of the cpl.log file in your run directory.
(seq_mct_drv): =============== SUCCESSFUL TERMINATION OF CPL7-CCSM ===============
Set it to resubmit itself 10 times so that it will run a total of 11 years (including the initial year), and resubmit the case. (Note that a resubmit will automatically change the run to be a continuation run).
> xmlchange RESUBMIT=10 > ./EXAMPLE_CASE.submit
