[MITgcm-devel] tutorial_global_oce_biogeo OpenAD results

[Oliver Jahn]

Hi Jean-Michel,

I kind of expected results to change with the change from global_sum_r8
to global_sum_tile_rl.  Why the TAF output didn't change, I do not know.
 Maybe generate a new output on baudelaire and see how different results
really are on acesgrid?
