[MITgcm-devel] convenience features for the adjoint

[Martin Losch]

Hi there,

I am glad I started this interesting discussion, I am not less confused than before. I think that I will do both:

1. adTapeDir will go into data/PARM05 and PARAMS.h (because mdsioLocalDir is in this place, and it is related)
2. In order to open the all floodgates for multiple new parameters, will put all of my use{PGK}inAdMode into a new data.autodiff/AUTODIFF_PARAMS.h. (and because this is really specific to the differentiation of the code)

And yes, I agree there are more urgent things to do, but I am not up to them (like fixing my adjoint run with GM), so I'll do the not-totally-unimportant things first (my style (o:). This was sparked by  debugging my configuration in the first place.

PS. Patrick, I disagree: Once this is implemented (also in autodiff_inadmode), the only thing that I need to specify is the parameter in data.autodiff. Or am I misssing something?
