4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/shelfice
8      in mom_fluxform.F, mom_vecinv.F:
9      CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
10      Bug fix KappaRU -> KappaRV
11      does not change verification/isomip but may change other setups
12      (presumably constant KappaRU=KappaRV)
13      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
14    o pkg/obcs:
15      - fixed some indexing bugs in obcs_seaice_sponge.F
16      - added obcs relaxation subroutines for HSALT and HSNOW
17      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
18    o pkg/seaice:
19      - add "multicategory" parameterization for snow in analogy to ice,
20        default is off for now.
21    o pkg/obcs:
22      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
23        see verification/seaice_obcs/input.seaiceSponge for example application.
24      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
25        index setting by master-thread. This fix multi-threads Pb in previous modifs.
26    o pkg/layers :
27      - add diagnostics to pkg/layers
28      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
29        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
30    o pkg/generic_advdiff/gad_implicit_r.F :
31      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
32    o pkg/seaice/seaice_growth.F:
33      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
34    o pkg/obcs:
35      - change default setting of OBCS_UVICE_OLD from defined to undef;
36      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
37        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
38      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
39      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
40        with Southern & Western OB at a tile edge (at least in a simple set-up).
41    o pkg/obcs:
42      - change settings of OB index in case OB coincides with tile edge (shared by
43        2 tiles), so that common OB location is registered by both tiles (instead of
44        only 1). However, for Southern and Western OB, index value = 0 is not
45        recognized as valid OB index (=default null value) and needs to be fixed.
46      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
47      - new parameter "OB_indexNone" for null index value (for now, still zero)
48        to replace hard-coded null index value of zero.
49    o pkg/exch2:
50      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
51        always check buffer-size (but outside the loop); move checking for valid
52        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
53        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
54    o pkg/ctrl (pack & unpack):
55      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
56        (locally defined) for different variables (+ remove the variable-specific
57        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
58        (to be extended to other local file names in ctrl.h).
59    o pkg/flt:
60      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
61    o pkg/mdsio:
62      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
63    o tools/genmake2:
64      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
65        (added by Alistair in version 1.51 for building without make depend);
66      - remove Header files list (H_SRC_FILES) from the dependence of targets
67         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
68        place in version 1.23): this save going through staf when unrelated header
69        file has been modified.
70       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
71        "make depend" step, still need to do "make links" before "make adtaf".
72    o eesupp/src (+ few pkg src files) & genmake2:
73      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
74      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
75      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
76         upper/lower case ; account for space between "#" and undef/define)
77    o pkg/flt (with exch2):
78      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
79      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
80    
81    checkpoint63s (2012/09/05)
82    o pkg/ecco:
83      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
84      - add more relevant #ifdef ALLOW_SMOOTH ones.
85      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
86    o pkg/ctrl:
87      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
88        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
89      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
90        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
91        ctrlSmoothCorrel3D (new).
92        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
93      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
94      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
95        controls when useAtmWind, and vice versa.
96      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
97      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
98          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
99      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
100          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
101      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
102        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
103    o pkg/smooth:
104      - remove un-necessary includes.
105      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
106        Those CPP options were never defined, and not necessary.
107    o model/src:
108      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
109      - standard treatment of useSMOOTH.
110    o pkg/autodiff:
111      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
112        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
113    o pkg/exch2:
114      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
115        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
116      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
117        and tiles to process mapping.
118      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
119        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
120        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
121        from w2_eeboot.F to w2_readparms.F.
122    o eesupp/src:
123      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
124        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
125        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
126      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
127        is defined (remove condition on usingMPI) to match cases where MPI_INIT
128        has been called.
129      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
130      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
131        (so that on 1 proc, get same myPid independently of usingMPI)
132      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
133        useCubedSphereExchange with EXCH-1 (safer).
134      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
135    o pkg/ggl90:
136      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
137        used in ALLOW_GGL90_SMOOTH code.
138    o pkg/flt:
139      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
140        floats at the Southern end of the domain).
141    o eesupp/inc:
142      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
143        but not used (and not to be used) anywhere, just for documentation.
144    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
145      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
146        a) can damage previously written records in any other multi-record files.
147        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
148    o tools/genmake2:
149      - define variable MAKE within Makefile and use it in place of 'make';
150      - update AD_CONFIG.h (if needed) before building any of the executable
151        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
152        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
153      - always print usual warning comment 'this file is automatically generated'
154        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
155    o pkg/cheapaml:
156      - updated to correspond to the code used in accepted paper (Nico Wienders).
157    o pkg/exf:
158        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
159        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
160        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
161    o pkg/exf, autodiff, ctrl, ecco and seaice:
162        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
163    o pkg/ctrl, ecco:
164        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
165        Depending on useAtmWind, one is inactive, and the other is active (see
166        exf_getffields.F/exf_getsurfacefluxes.F).
167    o tools/genmake2:
168      - improve error msg when failing in 2nd test of check_for_broken_Ff
169      - fix option '-makefile' short-name (-mf according to genmake2 -help)
170      - source local config file "genmake_local" just after processing the genmake2
171        command arguments (previously done before processing arg).
172    o pkg/grdchk:
173      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
174        to this routine from cost_final has been dropped in g_cost_final)
175      - improve printed information (more explicit msg, no longer using "print *,"
176         fix fcpertminus printed value).
177    o model/src:
178      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
179        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
180        this prevents getting cost-funct reset in adinitialise_varia recomputations.
181    o pkg/dic:
182      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
183        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
184    o pkg/grdchk:
185      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
186      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
187    o pkg/autodiff/ctrl/grdchk :
188      - attempt to sort out what works and what does not,
189        with regard to I/O, and to warn/stop accordingly.
190    o pkg/grdchk:
191      - attempt to fix grdchk in the case of useSingleCpuIO.
192      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
193       statements were moved from grdchk_main.F and into
194       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
195      - a global sum is applied to record numbers icvrec/layer
196       out of grdchk_loc so that they be passed to I/O routines.
197    o pkg/smooth:
198      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
199        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
200    o verification/testreport:
201      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
202      - can also use compressed (gzip) reference output file;
203      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
204        to be easier to collect by testreport.
205      - update existing TLM output (half out-of-date by more than 3 yrs).
206      - report NETCDF & LAPACK settings (from genmake2) in output dir.
207      - report run-time in each individual summary (previously only for AD test);
208        for TLM test, add also TAF version.
209      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
210    
211    checkpoint63r (2012/08/15)
212    o tools/genmake2:
213      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
214    o pkg/ecco/ecco_cost_final.F :
215      - fix fc print statements (to stdout and costfunction0000) so
216        that the printed value is always after the global sum.
217    o pkg/seaice/seaice_dynsolver.F :
218      - fix ice strength assymptote at SEAICE_area_max<1
219        (no change for the standard case of SEAICE_area_max=1)
220    o some cleaning:
221      - pkg source files: ensure that all *.F files from each pkg included the
222        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
223        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
224        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
225        includes;
226      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
227      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
228        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
229        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
230      - update option-file CPP_OPTIONS.h of all AD experiments:
231        * no longer include PACKAGES_CONFIG.h ;
232        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
233        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
234          including ECCO_CPPOPTIONS.h).
235    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
236      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
237        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
238        not necessary accurate).
239      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
240        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
241        deliberately break compilation (a remainder that it needs to be customized)
242      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
243      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
244      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
245    o tools/genamke2:
246      - check for lapack.
247    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
248      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
249        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
250        from both packages.
251      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
252      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
253      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
254        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
255    o pkg/cost : add comments to explain special and/or untested setups.
256    o pkg/exf:
257      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
258        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
259    o verification/*/code_ad:
260      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
261      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
262      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
263        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
264    o pkg/seaice :
265      - added possibility to change ice strength/PRESS0 relationship to
266        HEFF, according to the following run time parameters
267        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
268        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
269        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
270    o pkg/ggl90 :
271      - added run time flag mxlSurfFlag to include the code that ensure
272        mixing between first and second level (previously included as a comment)
273    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
274      - add test of newly added dumpAdByRec=T option where
275        we write all records to one file per variable.
276    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
277      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
278        to check that this code is ok with taf and compiles in adjoint.
279    o pkg/autodiff :
280      - added run time param dumpAdByRec : ad dump format switch.
281        If true then write all records to one file per variable.
282        Else write one file per record (remains the default).
283      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
284    o pkg/seaice:
285     - Added SEAICEuseTILT run time switch : if set to
286       false then omit the tilt term in seaice dynamics.
287     - Fix free drift calculation.
288    o pkg/shelfice:
289      When initializing SHELFICEDragQuadratic, set default to be
290      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
291      but retain option to set it independently
292      (inconsistenty spotted by Veronique Dansereau)
293    o eesupp/inc:
294      - in EEPARAMS.h, add real-type constant for some frequently used simple number
295         (0,1,2,1/2), with name explicitly referring to RS/RL type.
296    o model/src:
297      - move balancing of relaxation terms to new S/R balance_relax.F.
298    o pkg/autodiff:
299      re-write active I/O high-level (control) S/R:
300      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
301      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
302      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
303        MDS_READ/WRITE_FIELD); change loops to multi-threads.
304      - update and merge active_file_control_slice.flow into active_file_control.flow
305      - update the calls in lower level S/R (active_file.F, active_file_g.F and
306        active_file_ad.F) keeping the argument list and function unchanged.
307      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
308        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
309      - new low-level active I/O routines, one for each type (RL/RS), for active var
310        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
311        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
312        right type.
313    o autodiff and RS=real*4:
314      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
315        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
316      - change argument type of 3-D mask argument to _RS to match type in the call
317        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
318    o pkg/thsice:
319      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
320      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
321        fresh-water flux: uniform correction or proportional to local precip.
322    o pkg/ctrl:
323      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
324      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
325                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
326      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
327    
328    checkpoint63q (2012/07/30)
329    o pkg/autodiff:
330      note about monitor and snap-shot of ad-variables:
331      a) need to apply ADEXCH before monitor or output of ad-vars to include
332       overlap contributions (was done for adjDump but missing for monitor).
333      b) since ADEXCH implies adding overlap values to interior array, machine
334       truncation error is expected when adding an ADEXCH call in the middle of
335       the time-stepping (although mathematically identical).
336      modifs:
337      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
338        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
339      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
340        apply ADEXCH before monitor or snap-shot of ad-variables:
341           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
342      - implement new method (copy+adexch) for snap-shot and monitor of main model
343        ad-vars (initially not used by default -> output unchanged).
344      - change default (set to 2) to use new method and update few output_adm.txt
345        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
346        and both tutorial_tracer_adjsens tests).
347      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
348        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
349    o pkg/ctrl:
350      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
351      generic control variables via
352      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
353      Only required customization should be S/R ctrl_map_ini_genarr.F
354      (routine in repository contains example)
355    o pkg/exf:
356      - fix and refine checking of surface-relaxation setting when using EXF
357    o verification (adjoint exp):
358      - reduce length of simulation by half for experiment global_ocean.cs32x15
359        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
360    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
361      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
362        of KE that can occur with aggressive optimization
363      + put quadratic bottom drag calculation in separated loops (only done if
364        using bottomDragQuadratic)
365    o model/src: CG2D_NSA
366      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
367         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
368      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
369         change cg2d residual target to be expressed in Wunits (=> do not normalise
370         RHS ; this fix global_max Pb with TAF); update output.
371    o verification/tutorial_tracer_adjsens:
372       improve parameter consistency (and get rid of warnings):
373       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
374       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
375       - use staggerTimeStep (for stability) in som81; use default rotation period.
376    o pkg/exch2:
377      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
378        reset to 0 = 1 long line in X)
379    o pkg/mdsio:
380      - fix reading of dimensions from meta file for large-size domain
381    o model/src:
382      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
383      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
384        Cubed-Sphere Exch with CS-corners inside the domain;
385        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
386        globalArea and to set hasWetCSCorners.
387      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
388        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
389      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
390        useCDscheme and useCubedSphereExchange).
391    o pkg/seaice/seaice_growth.F :
392      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
393        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
394        when the previous code was not correct.
395      - in all cases diagnoze the boundary condition mismatch to SIaaflux
396      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
397        that term to QNET (essentially to set the melt/freeze water to 0degC).
398        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
399    o verification/global_ocean.cs32x15/input.seaice :
400      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
401      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
402      - update results (output.seaice.txt) accordingly.
403    o verification/lab_sea/input/data.seaice :
404      - remove SEAICEheatConsFix, which is now be tested
405        in global_ocean.cs32x15. The presently coded fix
406        is only consistent with real fresh water + nlfs.
407      - update results (output.txt) accordingly.
408    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
409    o AD_CONFIG.h file:
410      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
411      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
412        add it explicitly in each fortran src file where it is needed.
413        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
414        thus introducing potentially wrong dependency; therefore, better to include
415        it only where it's really needed, and after any other included OPTIONS file
416        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
417        or ALLOW_TANGENTLINEAR_RUN).
418    
419    checkpoint63p (2012/07/06)
420    o pkg/autodiff:
421      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
422      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
423        which are now read from new parameter file "data.autodiff" (inAdExact
424        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
425      - add file "data.autodiff" in all verification/*/input_ad/ directories.
426      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
427        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
428    o verification/tutorial_tracer_adjsens/
429      - add extra sub-verification which uses "SOM" advection scheme
430        (2nd Order-Moment Advection Scheme, Prather Limiter) with
431          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
432        and in data:
433          multiDimAdvection=.TRUE.,
434          tempAdvScheme=81,
435          saltAdvScheme=81,
436    o model/src:
437      - introduce ALLOW_BALANCE_RELAX which allow the removal
438       of the global mean of relaxation terms by setting
439       balanceThetaClimRelax and balanceSaltClimRelax
440      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
441       This case is now treated appropriately in seaice_growth.F
442    o pkg/seaice:
443      - do balanceEmPmR and balanceQnet based on the net fluxes
444        (SItflux) that enter the ocean+ice system rather than QNET
445        and EMPMR. Works best in real fresh water.
446      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
447        out of the diagnotics bloc, and stored in global arrays.
448    
449    checkpoint63o (2012/06/29)
450    o vertical mixing schemes:
451      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
452      - replace computation of density (in Function STATE1, opps_calc.F) by a call
453        to S/R FIND_RHO_SCALAR
454      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
455        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
456        affects output (vermix.ggl90) at truncation level.
457    o testreport:
458      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
459        (nSx,nSy) for the number of threads (from eedata.mth)
460    o model/src:
461      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
462        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
463    o verification/tutorial_tracer_adjsens/
464      - compile with ALLOW_CG2D_NSA
465      - run with nonlinFreeSurf=3
466      - update reference output_adm.txt
467    o tools/genmake2:
468      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
469        refine usePROFILES switching off (only when NetCDF is not available).
470    o verification (atmospheric set-up):
471      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
472    o pkg/profiles : refine profiles and files handling.
473    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
474    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
475      - changes to use model/src/the_main_loop.F rather than the ecco version
476        in ecco type adjoint runs.
477    o model/src:
478      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
479      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
480      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
481    o model/src:
482      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
483        update output of test experiment bottom_ctrl_5x5.
484    o pkg/generic_advdiff:
485      - implement vertical bi-harmonic diffusion (for now, only for T & S and
486        only explicitly).
487    o verification/bottom_ctrl_5x5/
488      update reference output (results changed quite some time ago,
489      not sure when; but new reference results look ok in terms of grdchk)
490    o verification/1D_ocean_ice_column/
491      For verification purposes, the exact adjoint rather than an approx.
492      should be used (e.g., to comare against F.D. or TLM).
493      removed autodiff_inadmode*_ad.F routines in code_ad/
494      Update results/ accordingly.
495    o pkg/cal:
496      - change cal_getdate.F so that output date is function of input time only
497        (less ambiguous, not mixed up with input iteration number).
498      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
499    o pkg/diagnostics:
500      - implement calendarDumps also for stats-diags
501      - implement calendarDumps also for snap-shot output (negative freq)
502      - for now, ignores calendarDumps if non-zero phase-lag.
503    
504    checkpoint63n (2012/06/04)
505    o model/src:
506      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
507        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
508      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
509        similar to calc_r_star.F); update results of experiment internal_wave and
510        tutorial_global_oce_in_p (affected @ truncation level).
511    o pkg/shelfice:
512      - add parameterisation of advective-diffusive flux into the ice shelf
513        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
514      - simply eps3/3a computation
515    o eesupp:
516     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
517       between tiles, just fill-in edges assuming locally periodic subdomain) and
518       add corresponding exchange subroutines (EXCH0);
519     - new CG-solver version (_EX0) for disconnected-tiles special case.
520    o model/src (CG-solvers):
521     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
522       (similar final residual output and max-Iter number as with standard version);
523     - allows to store and use lowest-residual solution (standard & _SR versions);
524     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
525     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
526    o eesup/src:
527     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
528       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
529    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
530    
531    checkpoint63m (2012/04/27)
532    o pkg/shelfice:
533     - account for partical cells in surface level below ice-shelf for hydrostatic
534       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
535    o ad test experiments:
536     - update and rename to "ad_optfile.local" local AD-optfile specific to a
537       particular adjoint verification experiment (in verification/*/code_ad/)
538    o pkg/seaice & pkg/exf:
539     - Part two of ECCO-CLIVAR code merges.
540       Completes merge of seaice area relax. code.
541       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
542       to be set in EXF_OPTIONS.h since this pkg controls its I/O
543       (and avoids second CPP option in SEAICE_OPTIONS.h)
544     - change default value of costIceStart & costIceEnd to a valid date.
545     - add snowPrecip to HSNOW in seaice_growth
546    o pkg/ptracers:
547     - move ptracers summary and setup check into separated S/R ; add a check for
548       valid PTRACERS_Iter0 value (error+stop or just warning).
549    o pkg/cal (+ pkg/ecco):
550     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
551       as input; and for AD, unless both are not differentiable (e.g., k index)).
552  o model/src:  o model/src:
553   - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index   - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
554     is everywhere k=1) to speed-up some calculations (by pass kSurf reference);     is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
