Info

Note:  If no config.h file is found in the experiment directory, and if also no command line parameters are provided when calling oifs-run, then oifs-run will revert to its own default values which are not appropriate. In any case you should either edit the config.h file appropriately or provide the correct command line parameters.

The config.h file contains the following settings:

Code Block
languagebash
OIFS_EXPID="aaaa"       # your experiment ID
OIFS_NPROC=1            # the number of MPI tasks
OIFS_NTHREAD=1          # the number of OpenMP threads
OIFS_GRIDTYPE="l"       # the grid type, either 'l' for linear reduced grid, or 'o' for the cubic octahedral grid
OIFS_RES="159"          # the spectral grid resolution
OIFS_NAMELIST='fort.4'  # the name of the atmospheric namelist file (default is fort.4)
OIFS_EXE="${OIFS_HOME}/build/bin/ifsMASTER.DP"  # the name and location of the model binary executable
OIFS_PPROC=false        # enable postprocessing of model output after the model run
OUTPUT_ROOT=$(pwd)      # folder where pproc output is created (only used if OIFS_PPROC=true)
LFORCE=false            # overwrite existing symbolic links in the experiment directory
LAUNCH=""               # platform specific run command for the MPI environment (e.g. "srun")
