The subroutine has been restructured to push the i-loop further down to extract vectorization and parallelization. The restructuring also involves introduction of sat_mixrat_liq_acc routines to extract parallelism when called inside a OpenACC parallel region. Porting: OpenACC directives are inserted to port the restructured compute_mixing_length code on to the GPUs. This port is currently unoptimized and there is still room for improvement. NOTE: Currently, l_sat_mixrat_lookup = false and saturation_formula = saturation_flatau (Earthworks config options) case is supported on OpenACC build. Any other options works on CPUs as usual. OpenACC declare create directives are inserted in model_flags and constants_clubb, as these module variables are used inside the saturation routines. * Added debug message about only supporting l_sat_mixrat_lookup = false and saturation_formula = saturation_flatau on GPUs Answers are Bit for Bit with arm-multicolumn case + nvhpc compiler. * Changing CLUBB debug level 1 to 0 for the saturation formula support running on GPUs * Changing indentation to make gfortran happy, it wants ifdefs to start at the beginning of the line. * Adding use statements for error checks and printouts, also making the errors set err_code to clubb_fatal_error.
