######################

Current setup is 1-year 1979, on 15 procs
-----------------------------------------
o cost terms are 
  * theta/salt climatology (incl. annual cycle)
  * SST, SSS
  * daily seaice concentration
  (see code_ad/ECCO_CPPOPTIONS.h, 
  input_ad/data.ecco, input_ad/data.seaice)
o forward part has all kpp, gmredi, seaice,
  adjoint part has SEAICEuseDYNAMICS=.FALSE., see
  code_ad/autodiff_inadmode_set_ad.F
  code_ad/autodiff_inadmode_unset_ad.F

To build code (on columbia):
---------------------------
cd build/
../../../tools/genmake2 -of ../../../tools/build_options/linux_ia64_ifort+mpi_altix_nas -mods ../code_ad
make depend
make adtaf
make -j adall

To run the code:
---------------
Currently:
Need input parameter files from input_ad/
Need input fields from /nobackup2a/heimbach/ecco/arctic40km/data/input/

Optimization/linesearch:
-----------------------
