Go through questions from last week: Jan 20
More questions:

  • Are there more special config options that make sense? (stand-alone modes for each component?) – Stage-2 Question
    • For example: (atmlnd_only, no_lnd)
  • Top level restarts for coup_csm version? – Examine with CAM group
  • Timemgr namelist for coup_csm version? – ditto
    Questions for next time:
  • Revist top level picture again – especially how states handled.
  • List of behavior of namelist items – what you can or can not set on branch or continue?
  • Error codes instead of abort?
    Look at new top level design with run methods: 
       subroutine ccsm_seq_run( esmfsync_clock, initinfo )
   type(ESMF_Clock), intent(in) :: esmfsync_clock
   type(initinfo_t), intent(in) :: initinfo

  ! Averaging rules   components are responsible for any averaging done on within 
  ! their coupling interval. Hub will average atmosphere fields for surface components
  ! and put the average on the given surface component import state. Hub will also average
  ! surface data to the atmosphere model coupling interval and put it on the atm import
  !  state
