How to run regression tests for the DATM MOM6 CICE6 model

How to run new regression tests for the DATM-MOM6-CICE6 model

• $ git clone https://github.com/ufs-community/ufs-weather-model DATM-MOM6-CICE6
• $ cd DATM-MOM6-CICE6
• $ git submodule update --init --recursive
• $ cd tests
• $ cp rt.conf rt.conf_datm
• Modify rt.conf_datm so that only the last 5 lines are kept:

COMPILE | DATM=Y S2S=Y       | standard | hera.intel orion.intel | fv3 |
RUN     | datm_control_cfsr  | standard | hera.intel orion.intel | fv3 |
RUN     | datm_control_gefs  | standard | hera.intel orion.intel | fv3 |
RUN     | datm_mx025_cfsr    | standard | hera.intel orion.intel | fv3 |
RUN     | datm_mx025_gefs    | standard | hera.intel orion.intel | fv3 |

• $ vi rt.sh (The default account to use is nems. If you cannot use nems account to run jobs, please change the "ACCNR" parameter, e.g., ACCNR=marine-cpu
• $ rt.sh -k -l rt.conf_datm (This command will compile the code using CMake and run all 4 test cases. After the runs are completed, the run directories are not removed.)
• The run directories are located at /scratch1/NCEPDEV/stmp2/${USER}/FV3_RT on Hera.
• The run directories are located at /work/noaa/stmp/${USER}/stmp/${USER}/FV3_RT on Orion.
