For your perusal when developing the new coarray code: A "mock" weather forecasting program using coarrays.

[Toon Moene]

Thomas, Nicolas,

The attached program doesn't do any physics, but it goes through the
motions of computing and communications like the real thing.

I tested it with opencoarrays, and it does a convincing run with the
following command line (i.e., an empty configuration namelist):

echo ' &config /' | cafrun -np 9 ./a.out

Hope it is useful for you.
