Eophis

Eophis is a collection of tools to ease the deployment of Python scripts (as pre-trained Machine Learning components) within Fortran/C geoscientific models through OASIS.

Also it is the currently oldest known snake ancestra (2023)

Strategy

OASIS is a parallelized Fortran coupling library that performs field exchanges between coupled executables. Last releases provided C and Python APIs, which enable coupling between non-homogeneously written codes. Basically, Eophis allows to:

• (i) wrap an OASIS interface to exchange data with a coupled physic-based code
• (ii) wrap inference models into a simple in/out interface
• (iii) emulate time evolution to synchronize connexions between scripts.

Current development objectives

• tools to write coupling info in geoscientific codes namelists
• tools for time diagnostic
• enhance packaging
• add more detailed tutorial

Usage, installation and test cases
