[mesa-users] extras_check_model versus extras_finish_step

[Bill Paxton]

Hi Ehsan,

Good question.   Let's look in star/job/run_star_support to get the answer.

Here's the call on extras_check_model:

            step_loop: do ! may need to repeat this loop
            
               if (stop_is_requested()) then
                  continue_evolve_loop = .false.
                  result = terminate
                  exit
               end if
            
               result = star_evolve_step(id, first_try, just_did_backup)
               if (result == keep_going) result = star_check_model(id)
               if (result == keep_going) result = extras_check_model(s, id, id_extra)
               if (result == keep_going) result = star_pick_next_timestep(id)            
               if (result == keep_going) exit step_loop

This is followed by code to take care of redo, retry, backup, or terminate.
So extras_check_model is called 1st and can request any of those.

The call on extras_finish_step comes after we have accepted the step.
It can terminate the run, but it cannot request a redo, retry, or backup.

Hope that helps,
Bill
