Turning on debug in compilation

Use the following settings to turn on debug/traceback options:

For NEMS and FV3:
In conf/configure.fv3.{machine} in the FLAGS section set: 
DEBUG = Y

For CICE:
In CICE/bld/Macros.Linux.NEMS.$MACHINE_ID update the FFLAGS:
FFLAGS     := -g -O0 -fp-model precise -convert big_endian -assume byterecl -ftz -traceback   -xHost -I$(NETCDF)/include

For MOM6:
In MOM6/src/mkmf/templates/{$MACHINE_ID}-intel.mk in the FLAGS section set: 
DEBUG = Y

Turning off ESMF PET logs

In parm/model_configure.IN, ESMF PET logs are turned on automatically. To turn off ESMF PET logs, change

print_esmf: .true.

to

print_esmf: .false.

Using ESMF in debug mode

To do this you need to change the loaded ESMF module. The module file location can be found by looking in the conf/before_components.mk file at the CHOSEN_MODULE variable. For computing system Hera, the location is modulefiles/hera.intel/fv3_coupled. To use ESMF in debug mode, change

module load esmf/8.0.0

to

module load esmf/8.0.0g
