Hi All,

Can I please get feedback from those with historical knowledge about the compiler flags used by access-om2. In particular, what compiler flags can we remove?

I’ve collated the compiler flags we currently use here:

> <https://github.com/ACCESS-NRI/ACCESS-OM/issues/12>
>
> Document compiler flags of the following components:
> \* oasis3-mct
> \* libaccesso…m2
> \* cice5
> \* mom5

Thanks,  
Harshula

Good question. Many of these were chosen after careful investigation, e.g. work by Paul Leopardi (NCI) on reproducibility between Gadi and the previous system (Raijin), and scaling on Gadi - see
