4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
8      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions jointly.
9       The exclusive ifdefs were removed, to add costs terms (when defined) from both packages.
10      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
11      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
12      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes of
13       "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
14    o pkg/cost : add comments to explain special and/or untested setups.
15    o pkg/exf:
16      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
17        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
18    o verification/*/code_ad:
19      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
20      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
21      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
22        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
23    o pkg/seaice :
24      - added possibility to change ice strength/PRESS0 relationship to
25        HEFF, according to the following run time parameters
26        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
27        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
28        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
29    o pkg/ggl90 :
30      - added run time flag mxlSurfFlag to include the code that ensure
31        mixing between first and second level (previously included as a comment)
32    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
33      - add test of newly added dumpAdByRec=T option where
34        we write all records to one file per variable.
35    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
36      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
37        to check that this code is ok with taf and compiles in adjoint.
38    o pkg/autodiff :
39      - added run time param dumpAdByRec : ad dump format switch.
40        If true then write all records to one file per variable.
41        Else write one file per record (remains the default).
42      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
43    o pkg/seaice:
44     - Added SEAICEuseTILT run time switch : if set to
45       false then omit the tilt term in seaice dynamics.
46     - Fix free drift calculation.
47    o pkg/shelfice:
48      When initializing SHELFICEDragQuadratic, set default to be
49      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
50      but retain option to set it independently
51      (inconsistenty spotted by Veronique Dansereau)
52    o eesupp/inc:
53      - in EEPARAMS.h, add real-type constant for some frequently used simple number
54         (0,1,2,1/2), with name explicitly referring to RS/RL type.
55    o model/src:
56      - move balancing of relaxation terms to new S/R balance_relax.F.
57    o pkg/autodiff:
58      re-write active I/O high-level (control) S/R:
59      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
60      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
61      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
62        MDS_READ/WRITE_FIELD); change loops to multi-threads.
63      - update and merge active_file_control_slice.flow into active_file_control.flow
64      - update the calls in lower level S/R (active_file.F, active_file_g.F and
65        active_file_ad.F) keeping the argument list and function unchanged.
66      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
67        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
68      - new low-level active I/O routines, one for each type (RL/RS), for active var
69        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
70        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
71        right type.
72    o autodiff and RS=real*4:
73      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
74        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
75      - change argument type of 3-D mask argument to _RS to match type in the call
76        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
77    o pkg/thsice:
78      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
79      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
80        fresh-water flux: uniform correction or proportional to local precip.
81    o pkg/ctrl:
82      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
83      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
84                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
85      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
86    
87    checkpoint63q (2012/07/30)
88    o pkg/autodiff:
89      note about monitor and snap-shot of ad-variables:
90      a) need to apply ADEXCH before monitor or output of ad-vars to include
91       overlap contributions (was done for adjDump but missing for monitor).
92      b) since ADEXCH implies adding overlap values to interior array, machine
93       truncation error is expected when adding an ADEXCH call in the middle of
94       the time-stepping (although mathematically identical).
95      modifs:
96      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
97        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
98      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
99        apply ADEXCH before monitor or snap-shot of ad-variables:
100           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
101      - implement new method (copy+adexch) for snap-shot and monitor of main model
102        ad-vars (initially not used by default -> output unchanged).
103      - change default (set to 2) to use new method and update few output_adm.txt
104        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
105        and both tutorial_tracer_adjsens tests).
106      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
107        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
108    o pkg/ctrl:
109      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
110      generic control variables via
111      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
112      Only required customization should be S/R ctrl_map_ini_genarr.F
113      (routine in repository contains example)
114    o pkg/exf:
115      - fix and refine checking of surface-relaxation setting when using EXF
116    o verification (adjoint exp):
117      - reduce length of simulation by half for experiment global_ocean.cs32x15
118        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
119    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
120      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
121        of KE that can occur with aggressive optimization
122      + put quadratic bottom drag calculation in separated loops (only done if
123        using bottomDragQuadratic)
124    o model/src: CG2D_NSA
125      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
126         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
127      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
128         change cg2d residual target to be expressed in Wunits (=> do not normalise
129         RHS ; this fix global_max Pb with TAF); update output.
130    o verification/tutorial_tracer_adjsens:
131       improve parameter consistency (and get rid of warnings):
132       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
133       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
134       - use staggerTimeStep (for stability) in som81; use default rotation period.
135    o pkg/exch2:
136      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
137        reset to 0 = 1 long line in X)
138    o pkg/mdsio:
139      - fix reading of dimensions from meta file for large-size domain
140    o model/src:
141      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
142      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
143        Cubed-Sphere Exch with CS-corners inside the domain;
144        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
145        globalArea and to set hasWetCSCorners.
146      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
147        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
148      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
149        useCDscheme and useCubedSphereExchange).
150    o pkg/seaice/seaice_growth.F :
151      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
152        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
153        when the previous code was not correct.
154      - in all cases diagnoze the boundary condition mismatch to SIaaflux
155      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
156        that term to QNET (essentially to set the melt/freeze water to 0degC).
157        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
158  o verification/global_ocean.cs32x15/input.seaice :  o verification/global_ocean.cs32x15/input.seaice :
159   - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.    - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
160   - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).    - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).

167  o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).  o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
168  o AD_CONFIG.h file:  o AD_CONFIG.h file:
169   - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;    - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
170   - remove #include "AD_CONFIG.h" from all included OPTIONS files and    - remove #include "AD_CONFIG.h" from all included OPTIONS files and
