Ralf,

as you've already heard from Detlef's email we have
frozen the work on your release for the time being.
The reason is that time to get an acceptable running version
for the global state estimation is pressing,
and there are still too many problems with your release,
related to robustness and ease to use, as well as to
the actual content of the code, whereas tests with the
"mit" version are quite advanced.

I know that's unfortunate for you since it jeopardizes some
of your work for the moment, but we have to work on it
in a way that everybody involved can work efficiently on the code.
We have agreed that cosmetic changes should not be done
for now until a stable code is available.
In particular, no changes in capitalization or variable names
should be done for now, especially not on the forward code.
Allthough half of the differences between the forward code
in your release and standard mitgcmuv are related to this
there are other changes, some of which are very likely to
be beneficial for the forward code.
I think the appropriate way to incorporate those changes
is to incorporate those into the standard model rather than
trying to keep your version up-to-date with the standard.
In this way, those changes can effectively be checked into
the standard.

Detlef has written you a summary of main problems.
The most pressing on which it would be very helpful if you could 
work on is related to the question of excessive core memory
for the ECCO code (including KPP).
The questions are 
- whether memory requirement of KPP might be reduced, 
- whether impldiff.F is implemented in an unfortunate way
- the storage reqiurement might be reduced by ignoring all
  level 1 TAMC warnings
- excessive storage is required because of the
  staggered time stepping or other reasons that might be
  solved easily.
  
Please let me know your thoughts on this and whether
you can work on it or what your plans are.

Thanks
Patrick
