5      ==============================      ==============================
6    
7    o adjoint with OpenAD:
8      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
9        package openad.  This package has to be compiled for all runs with OpenAD
10        instead of specifying code_oad_all as a modification directory.
11      - link the fortran templates from tools/OAD_support to the build directory
12        for preprocessing to avoid conflicts between different setups compiled
13        simultaneously and simplify cleanup.
14    o pkg/exf:
15      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
16        main model or other pkgs are exchanged in EXF_MAPFIELDS).
17    o model/src:
18      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
19        (similar to do_fields_blocking_exchanges.F).
20    o tools/genmake2:
21      - remove TAF output src code just before calling staf (when not doing a fresh
22        built, will stop if things go wrong with staf).
23      - fix target "adobj" (left from TAF version-2 transition)
24    o pkg/diagnostics:
25      - add a parameter to track the status of pkg/diagnostics activation;
26        this replace/extend the use of logical param "settingDiags" (to check
27        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
28        New S/R to print error message and stop when pkgStatus is not right.
29      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
30    
31    checkpoint64m (2013/08/13)
32    o model/inc:
33      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
34        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
35    o pkg/kpp & aim_v23:
36      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
37    o pkg/seaice:
38      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
39        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
40      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
41    o eesupp/src:
42      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
43        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
44    o switch to TAF version-2:
45      - add flow directives to "freeze" naming convention for ad-routines that
46        are used in I/O routines of adjoint state and associated common blocks
47        that are used in adcommon.h (backward compatible with version-1)
48      - update all ad-optfiles (in tools/adjoint_options + few local to some
49        verification exp) to switch to latest TAF version (currently 2.5.5);
50        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
51        out except for diva).
52      - the major change with TAF version-2 is that both the differentiated
53        routines and the forward routines (new) are returned as part of the TAF
54        output source code. Update genmake2 accordingly.
55      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
56        with version-2 when compared to TLM or FWD gradient); other experiments
57        output show minor changes (machine truncation level); update the few AD &
58        TLM output with 12 matching digits only (some prior to version-2 switch).
59    
60    checkpoint64l (2013/08/05)
61    o model/src:
62      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
63      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
64        when using TAF but only if using OpenAD.
65    o pkg/mom_common+fluxform+vecinv:
66      - always set horiz. viscosity arrays to background value before calling
67        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
68        only when using variable horiz. viscosity (useVariableVisc=T);
69      - simplify mom_vecinv.F (only 1 block for momViscosity).
70    o pkg/mom_common: variable horiz. viscosity in NH code
71      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
72        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
73      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
74        useBiharmonicVisc & useVariableVisc.
75      - fix old bug (already in 1rst implementation of variable horizontal viscosity
76        in calc_gw.F, version 1.27, 2006/06/20):
77        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
78        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
79      - change background horiz viscosity in vertical momentum (gW) to always be
80        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
81        any type of variable viscosity, e.g., viscAh/4Grid)
82      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
83        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
84        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
85        default viscAh,viscA4 is zero).
86    o model/src:
87      - extend length of drC & recip_drC from Nr to Nr+1.
88    o Divided Adjoint (DIVA) with MPI:
89      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
90      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
91        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
92    
93  checkpoint64k (2013/07/23)  checkpoint64k (2013/07/23)
94  o tools/OAD_support:  o tools/OAD_support:
95    - avoid the need for file "oadtempflile" in insertTemplateDir.bash    - avoid the need for file "oadtempflile" in insertTemplateDir.bash
