Using the Require_Species_in_Restart=1 setting in the setCommonRunSettings.sh script) will cause GCHP simulations to terminate without a corresponding error message (either in the gchp*log file or in allPEs.log). This can give the user a false idea as to what the failure was caused by.

I have also confirmed that no error message is given if the restart is not present in the run directory. GCHP will proceed to try to initialize Dynamics (and that is the last thing that gets written to allPEs.log.

The fixes for these issues will need to go into MAPL. Restarts are handled within the MAPL Generic component based on the restart attribute attached to each internal state variable. When we set Require_Species_in_Restart=1 in setCommonRunSettings.sh the restart attribute is set to required in GCHP subroutine SetServices.

@lizziel: I can open a corresponding PR on the MAPL repo.

Thank you!

I am running into this issue while testing RRTMG. I'll check on if we can do anything about it.

I have discussed this with GMAO developers and we now anticipate a fix in MAPL3 which will be part of GCHP 15.0.
