Python Interface to MAPL

This document presents a very high level description of a python interface to MAPL.

GEOS-5 Use Cases

The examples below are based on the actual GEOS-5 GCM Application, and a few components at the very top of the hierarchy. Here we assumed that MAPL Grid Components can be implemented entirely in C/Fortran or in Python.

GEOS-5 Application with Fortran Root Component =

In this example, the very top root component is implemented entirely in a shared library.

"""" The GEOSgcm application written in python, starting from a Root Component implemented in Fortran. """

import MAPL

if __name == "__main__":

1. Instantiate the root component
2. ------------------------------

   gcs = MAPL.GridComp(lib='/some/path/libGEOSana.so')

1. Instantiate MAPL, using a "Fortran" as a root component
2. -------------------------------------------------------

   mapl = MAPL(root=gcs)

1. Run the cap
2. -----------

   mapl.go()
