Assistance Needed: MPI Error While Generating HRLDAS Forcing Data for Croton Test Case Using genForcing.py

[Fatemeh Shirkhanloo]

Dear WRF-Hydro Users,

I am currently working on regenerating HRLDAS forcing data for the WRF-Hydro model, Croton test case. To do this, I downloaded the required NLDAS-2 forcing data from the NASA website:
https://ldas.gsfc.nasa.gov/nldas/nldas-2-forcing-data

I am using the genForcing.py script from the official WrfHydroForcing repository and the provided configuration file named template_forcing_engine_Short.config.

However, I am encountering the following error during execution:

File "/home/fatemehs/WrfHydroForcing/genForcing.py", line 140, in <module>
    main()
File "/home/fatemehs/WrfHydroForcing/genForcing.py", line 130, in main
    forecastMod.process_forecasts(job_meta, WrfHydroGeoMeta, inputForcingMod, suppPcpMod, mpi_meta, OutputObj)
File "/home/fatemehs/WrfHydroForcing/core/forecastMod.py", line 196, in process_forecasts
    input_forcings.calc_neighbor_files(ConfigOptions, OutputObj.outDate, MpiConfig)
File "/home/fatemehs/WrfHydroForcing/core/forcingInputMod.py", line 492, in calc_neighbor_files
    find_neighbor_files[self.keyValue](self, ConfigOptions, dCurrent, MpiConfig)
File "/home/fatemehs/WrfHydroForcing/core/time_handling.py", line 1612, in find_custom_hourly_neighbors
    err_handler.check_program_status(config_options, mpi_config)

Abort(0) on node 0 (rank 0 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 0) - process 0

I’ve spent a significant amount of time troubleshooting this issue but have not been able to resolve it. Could you please help me understand what may be causing this MPI abort and how I might fix it? Am I using right config file for Croton test case to generate HRLDAS forcing data? 

Any suggestions or guidance would be greatly appreciated.

Thank you in advance for your time and support.

Best regards,
