restart and input directories are the same #5

Closed aidanheerdegen closed 6 years ago

The information model for MOM (and I think other models) is for inputs to be read from one directory, outputs to be saved to different directory, and restarts to be saved into another unique directory. In this way the contents of the restart directory can be copied/linked to the input directory for the next run.

Currently sicemass, u_star and the coupling fields are read from restart_dir

and written to restart_dir

This can cause issues if these files are symbolic links then writing to them will overwrite the previous version of the restart file.

I would like to have separate INPUT and RESTART directories.

I think we've already talked about this, but just in case.. this is suggesting that CICE5 be modified to have INPUT and RESTART just like MOM. Is that right?

Is this still something you'd like to do?

My feeling is that I'd rather support something as close to stock CICE as possible, and accommodate this version, rather than make CICE5 into something MOM-like.

It isn't CICE we’re changing, but the AUSCOM driver code. In any case I’m testing a modified AUSCOM driver that is backwards compatible. When I’m satisfied it works without breaking old configs I’ll do a pull request so you can take a look

That all sounds good to me.

I lied. I did change CICE, but it is backwards compatible and doesn't break anything AFAICT.
