Restarted runs

It’s common to want to restart a model run from a previous experiment. This is possible in the workflow, but requires some configuration.

To restart a run from a previous experiment, you need to set the following parameters in your main.yml configuration file: - RUN.RESTARTED_RUN: This should be set to true to indicate that you want to restart a run. - RUN.RESTART_FROM: This should be set to the experiment ID (EXP_ID) of the run you want to restart from. This tells the workflow where to look for the restart files. - CONFIGURATION.IFS.START_DATE: This should be set to the start date of the run you want to restart from, in the format YYYYMMDD. This is used to pass the correct information to IFS. - (optional) MODEL.RESTART_FROM_PATH: This can be set to the specific path where the restart files are located. If not set, the workflow will assume a default path based on the RUN.RESTART_FROM and your user and project directories.

When you set these parameters, the workflow will copy the necessary restart files from the specified experiment to a new directory for the current run. The model will then use these files to restart from the specified point.

Note: it is currently only available for the IFS-NEMO model.
