- Suggested syntax:
$ ./create_newcase -case $CASENAME -compset FC5 -mach (your-machine-name-here) -res conusx4v1_conusx4v1 - Edit env_mach_pes.xml. For Redsky, using 200 cores and 1 thread for each component runs at 0.25 simulated years per day.
- Edit env_run.xml.
- For a 5 year free-run on Redsky, (throwing out 1 year)
- set RUN_STARTDATE equal to 0001-01-01
- set STOP_OPTION equal to nmonths
- set STOP_N equal to 12
- set REST_N equal to 6
- set RESUBMIT equal to 6
- set ATM_NCPL equal to 96
$ ./cesm_setup
$ ./$CASENAME.build (When building a case for the first time, the script will look for the boundary and initial condition files. The RRM team plans to push that data to the ACME server, /wiki/spaces/WORKFLOW/pages/7998629. Contact the RRM team for those files until the data is there. This page will be updated to reflect that change.) - For a 5 year free-run on Redsky, (throwing out 1 year)
- Edit user_nl_clm to include spun-up land initial condition file.
