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

5. Edit the user_nl_cam to include changes to the se-dycore.
