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