4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
8      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
9        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
10        not necessary accurate).
11      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
12        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
13        deliberately break compilation (a remainder that it needs to be customized)
14      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
15      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
16      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
17    o tools/genamke2:
18      - check for lapack.
19    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
20      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
21        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
22        from both packages.
23      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
24      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
25      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
26        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
27    o pkg/cost : add comments to explain special and/or untested setups.
28    o pkg/exf:
29      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
30        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
31    o verification/*/code_ad:
32      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
33      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
34      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
35        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
36    o pkg/seaice :
37      - added possibility to change ice strength/PRESS0 relationship to
38        HEFF, according to the following run time parameters
39        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
40        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
41        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
42    o pkg/ggl90 :
43      - added run time flag mxlSurfFlag to include the code that ensure
44        mixing between first and second level (previously included as a comment)
45    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
46      - add test of newly added dumpAdByRec=T option where
47        we write all records to one file per variable.
48    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
49      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
50        to check that this code is ok with taf and compiles in adjoint.
51    o pkg/autodiff :
52      - added run time param dumpAdByRec : ad dump format switch.
53        If true then write all records to one file per variable.
54        Else write one file per record (remains the default).
55      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
56    o pkg/seaice:
57     - Added SEAICEuseTILT run time switch : if set to
58       false then omit the tilt term in seaice dynamics.
59     - Fix free drift calculation.
60    o pkg/shelfice:
61      When initializing SHELFICEDragQuadratic, set default to be
62      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
63      but retain option to set it independently
64      (inconsistenty spotted by Veronique Dansereau)
65    o eesupp/inc:
66      - in EEPARAMS.h, add real-type constant for some frequently used simple number
67         (0,1,2,1/2), with name explicitly referring to RS/RL type.
68    o model/src:
69      - move balancing of relaxation terms to new S/R balance_relax.F.
70    o pkg/autodiff:
71      re-write active I/O high-level (control) S/R:
72      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
73      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
74      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
75        MDS_READ/WRITE_FIELD); change loops to multi-threads.
76      - update and merge active_file_control_slice.flow into active_file_control.flow
77      - update the calls in lower level S/R (active_file.F, active_file_g.F and
78        active_file_ad.F) keeping the argument list and function unchanged.
79      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
80        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
81      - new low-level active I/O routines, one for each type (RL/RS), for active var
82        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
83        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
84        right type.
85    o autodiff and RS=real*4:
86      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
87        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
88      - change argument type of 3-D mask argument to _RS to match type in the call
89        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
90    o pkg/thsice:
91      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
92      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
93        fresh-water flux: uniform correction or proportional to local precip.
94    o pkg/ctrl:
95      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
96      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
97                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
98      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
99    
100    checkpoint63q (2012/07/30)
101    o pkg/autodiff:
102      note about monitor and snap-shot of ad-variables:
103      a) need to apply ADEXCH before monitor or output of ad-vars to include
104       overlap contributions (was done for adjDump but missing for monitor).
105      b) since ADEXCH implies adding overlap values to interior array, machine
106       truncation error is expected when adding an ADEXCH call in the middle of
107       the time-stepping (although mathematically identical).
108      modifs:
109      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
110        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
111      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
112        apply ADEXCH before monitor or snap-shot of ad-variables:
113           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
114      - implement new method (copy+adexch) for snap-shot and monitor of main model
115        ad-vars (initially not used by default -> output unchanged).
116      - change default (set to 2) to use new method and update few output_adm.txt
117        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
118        and both tutorial_tracer_adjsens tests).
119      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
120        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
121    o pkg/ctrl:
122      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
123      generic control variables via
124      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
125      Only required customization should be S/R ctrl_map_ini_genarr.F
126      (routine in repository contains example)
127    o pkg/exf:
128      - fix and refine checking of surface-relaxation setting when using EXF
129    o verification (adjoint exp):
130      - reduce length of simulation by half for experiment global_ocean.cs32x15
131        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
132    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
133      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
134        of KE that can occur with aggressive optimization
135      + put quadratic bottom drag calculation in separated loops (only done if
136        using bottomDragQuadratic)
137    o model/src: CG2D_NSA
138      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
139         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
140      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
141         change cg2d residual target to be expressed in Wunits (=> do not normalise
142         RHS ; this fix global_max Pb with TAF); update output.
143    o verification/tutorial_tracer_adjsens:
144       improve parameter consistency (and get rid of warnings):
145       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
146       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
147       - use staggerTimeStep (for stability) in som81; use default rotation period.
148    o pkg/exch2:
149      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
150        reset to 0 = 1 long line in X)
151    o pkg/mdsio:
152      - fix reading of dimensions from meta file for large-size domain
153    o model/src:
154      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
155      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
156        Cubed-Sphere Exch with CS-corners inside the domain;
157        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
158        globalArea and to set hasWetCSCorners.
159      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
160        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
161      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
162        useCDscheme and useCubedSphereExchange).
163    o pkg/seaice/seaice_growth.F :
164      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
165        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
166        when the previous code was not correct.
167      - in all cases diagnoze the boundary condition mismatch to SIaaflux
168      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
169        that term to QNET (essentially to set the melt/freeze water to 0degC).
170        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
171    o verification/global_ocean.cs32x15/input.seaice :
172      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
173      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
174      - update results (output.seaice.txt) accordingly.
175    o verification/lab_sea/input/data.seaice :
176      - remove SEAICEheatConsFix, which is now be tested
177        in global_ocean.cs32x15. The presently coded fix
178        is only consistent with real fresh water + nlfs.
179      - update results (output.txt) accordingly.
180    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
181    o AD_CONFIG.h file:
182      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
183      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
184        add it explicitly in each fortran src file where it is needed.
185        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
186        thus introducing potentially wrong dependency; therefore, better to include
187        it only where it's really needed, and after any other included OPTIONS file
188        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
189        or ALLOW_TANGENTLINEAR_RUN).
190    
191    checkpoint63p (2012/07/06)
192    o pkg/autodiff:
193      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
194      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
195        which are now read from new parameter file "data.autodiff" (inAdExact
196        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
197      - add file "data.autodiff" in all verification/*/input_ad/ directories.
198      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
199        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
200    o verification/tutorial_tracer_adjsens/
201      - add extra sub-verification which uses "SOM" advection scheme
202        (2nd Order-Moment Advection Scheme, Prather Limiter) with
203          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
204        and in data:
205          multiDimAdvection=.TRUE.,
206          tempAdvScheme=81,
207          saltAdvScheme=81,
208    o model/src:
209      - introduce ALLOW_BALANCE_RELAX which allow the removal
210       of the global mean of relaxation terms by setting
211       balanceThetaClimRelax and balanceSaltClimRelax
212      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
213       This case is now treated appropriately in seaice_growth.F
214    o pkg/seaice:
215      - do balanceEmPmR and balanceQnet based on the net fluxes
216        (SItflux) that enter the ocean+ice system rather than QNET
217        and EMPMR. Works best in real fresh water.
218      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
219        out of the diagnotics bloc, and stored in global arrays.
220    
221    checkpoint63o (2012/06/29)
222    o vertical mixing schemes:
223      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
224      - replace computation of density (in Function STATE1, opps_calc.F) by a call
225        to S/R FIND_RHO_SCALAR
226      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
227        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
228        affects output (vermix.ggl90) at truncation level.
229    o testreport:
230      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
231        (nSx,nSy) for the number of threads (from eedata.mth)
232    o model/src:
233      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
234        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
235    o verification/tutorial_tracer_adjsens/
236      - compile with ALLOW_CG2D_NSA
237      - run with nonlinFreeSurf=3
238      - update reference output_adm.txt
239    o tools/genmake2:
240      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
241        refine usePROFILES switching off (only when NetCDF is not available).
242    o verification (atmospheric set-up):
243      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
244    o pkg/profiles : refine profiles and files handling.
245    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
246    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
247      - changes to use model/src/the_main_loop.F rather than the ecco version
248        in ecco type adjoint runs.
249    o model/src:
250      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
251      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
252      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
253    o model/src:
254      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
255        update output of test experiment bottom_ctrl_5x5.
256    o pkg/generic_advdiff:
257      - implement vertical bi-harmonic diffusion (for now, only for T & S and
258        only explicitly).
259    o verification/bottom_ctrl_5x5/
260      update reference output (results changed quite some time ago,
261      not sure when; but new reference results look ok in terms of grdchk)
262    o verification/1D_ocean_ice_column/
263      For verification purposes, the exact adjoint rather than an approx.
264      should be used (e.g., to comare against F.D. or TLM).
265      removed autodiff_inadmode*_ad.F routines in code_ad/
266      Update results/ accordingly.
267    o pkg/cal:
268      - change cal_getdate.F so that output date is function of input time only
269        (less ambiguous, not mixed up with input iteration number).
270      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
271    o pkg/diagnostics:
272      - implement calendarDumps also for stats-diags
273      - implement calendarDumps also for snap-shot output (negative freq)
274      - for now, ignores calendarDumps if non-zero phase-lag.
275    
276    checkpoint63n (2012/06/04)
277    o model/src:
278      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
279        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
280      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
281        similar to calc_r_star.F); update results of experiment internal_wave and
282        tutorial_global_oce_in_p (affected @ truncation level).
283    o pkg/shelfice:
284      - add parameterisation of advective-diffusive flux into the ice shelf
285        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
286      - simply eps3/3a computation
287    o eesupp:
288     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
289       between tiles, just fill-in edges assuming locally periodic subdomain) and
290       add corresponding exchange subroutines (EXCH0);
291     - new CG-solver version (_EX0) for disconnected-tiles special case.
292    o model/src (CG-solvers):
293     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
294       (similar final residual output and max-Iter number as with standard version);
295     - allows to store and use lowest-residual solution (standard & _SR versions);
296     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
297     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
298    o eesup/src:
299     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
300       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
301    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
302    
303    checkpoint63m (2012/04/27)
304    o pkg/shelfice:
305     - account for partical cells in surface level below ice-shelf for hydrostatic
306       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
307    o ad test experiments:
308     - update and rename to "ad_optfile.local" local AD-optfile specific to a
309       particular adjoint verification experiment (in verification/*/code_ad/)
310    o pkg/seaice & pkg/exf:
311     - Part two of ECCO-CLIVAR code merges.
312       Completes merge of seaice area relax. code.
313       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
314       to be set in EXF_OPTIONS.h since this pkg controls its I/O
315       (and avoids second CPP option in SEAICE_OPTIONS.h)
316     - change default value of costIceStart & costIceEnd to a valid date.
317     - add snowPrecip to HSNOW in seaice_growth
318    o pkg/ptracers:
319     - move ptracers summary and setup check into separated S/R ; add a check for
320       valid PTRACERS_Iter0 value (error+stop or just warning).
321    o pkg/cal (+ pkg/ecco):
322     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
323       as input; and for AD, unless both are not differentiable (e.g., k index)).
324    o model/src:
325     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
326       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
327       temporary set to usingZCoords value (to be changed to F when using shelfice).
328     - hydrostatic pressure: implement partial cell near the surface also for
329       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
330       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
331    o pkg/ctrl/ctrl_init.F:
332     - add a formal parameter to s/r ctrl_init_rec to print
333       xx_$(ctrl_valiable)_file for easier debugging
334     - move call of cal_* routines into the if-block where they are really
335       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
336       to specify a startdate
337    o pkg/seaice:
338     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
339       global_ocean.cs32x15/code versions).
340     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
341       verification experiment global_ocean.cs32x15.seaice and update results.
342    o pkg/exf:
343     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
344       (according to useExfYearlyFields).
345    o pkg/cal:
346     - move calendar setting & summary (previously in cal_readparams.F) into new
347       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
348       length of the simulation is set (after SET_PARMS call); This is an attempt
349       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
350     - For safety: keep a record of pkg/cal parameter settings status
351               to allow to STOP if one pkg/cal S/R is called too early.
352     - add a stop in all basic pkg/cal subroutines if called before setting is done.
353     - modify cal_getdate.F: stop when nothing was returned;
354       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
355       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.

357    checkpoint63l (2012/04/04)
358    o pkg/bbl:
359      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
360        update global_with_exf output.yearly.txt file.
361    o pkg/cal:
362      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
363      - remove 2 unsused and very short (1 line only) functions ;
364      - remove unsused subroutines from AD-Diff list.
365    o model/src:
366      - start to implement clean wait to stop in initialization S/R (config_check.F,
367         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
368    o folowing PRINT_MESSAGE changes:
369      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
370  o pkg/bbl:  o pkg/bbl:
371    - modification so it can work with z*    - modification so it can work with z*
372    - replace deltaT with dTtracerLev(k) for asynchronous time stepping    - replace deltaT with dTtracerLev(k) for asynchronous time stepping
