Dear CESM users,
I need some clarification on deciding the run type for 2 set of experiments. For both of these experiment I want to use the restart file from a run say a control run X.
1.) I want to continue the run X with exactly same specifications but changed some of resource/machine related things such as (number of processor/nodes etc.). Since, everything is going to be same with run X, Can i select the run_type='branch' for this and follow the guidelines for starting a branch run? as per my understanding this will continues the run X from the restart check points?
2.) for the second type of run, I want to use the restart files from the check point from the run X stopped. But for this new run, I want to make several changes such as
a.) a compset type but for similar type of experiment (such as F-compset for 1850 and hist, so that everything related with the model components is consistent between X and this run).
b.) I also want to change some input files, such as Findata, surfdata etc and namelist variable controlling the CO2 to diagnostic and fixed etc.
c.) also, I want to change the start dates for this new run. but want the model initialization from the X (restart files).
For this category of runs, I assume that I should follow guidelines for a 'hybrid' run by setting the run_type='hybrid'.
Please clarify if my understanding the run_types (branch and hybrid) is okay and I will be able to start those 2 desired set of run using the restart files from control run X.
Also, please correct or mention if I missed something or stated above incorrectly.
Thank you very much.
