[MITgcm-devel] Problem with pkg/bbl addition in adjoint lab_sea exp.

[Jean-Michel Campin]

Hi Dimitris,

Looks like the pkg/bbl changes in do_oceanic_phys.F are likely
responsible for many more recomputations in lab_sea AD test
(because pkg/down_slope is in lab_sea/code_ad/packages.conf):
yesterday:
 TAF reports 1 Errors and 25 Recomputation Warnings
today:
 TAF reports 1 Errors and 91 Recomputation Warnings

And the additional ones are like:
< TAF RECOMPUTATION WARNING IF_STMT ad_input_code.f:XXX in the_main_loop
<  triggered by      : rhoinsitu
<  still to be recomputed : rhoinsitu

I suggest that this should be fixed (+ get 1 night clean AD testing)
before turning on useBBL in global_ocean.cs32x15/input/data.pkg

Cheers,
Jean-Michel
