4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o eesupp/src:
8      - check in genmake2 that intrinsic S/R flush is available.
9      - add S/R to flush IO unit (if intrinsic S/R flush is available)
10      - flush standard & error msg unit before MPI termination
11      - if debugMode, flush IO unit after printing msg
12    o pkg/ctrl:
13      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
14        to ctrl_set_unpack_xyz.
15    
16    checkpoint64 (2012/10/09)
17    o pkg/shelfice
18      - in mom_fluxform.F, mom_vecinv.F:
19        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
20        Bug fix KappaRU -> KappaRV
21        does not change verification/isomip but may change other setups
22        (presumably constant KappaRU=KappaRV)
23      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
24    o pkg/obcs:
25      - fixed some indexing bugs in obcs_seaice_sponge.F
26      - added obcs relaxation subroutines for HSALT and HSNOW
27      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
28    o pkg/seaice:
29      - add "multicategory" parameterization for snow in analogy to ice,
30        default is off for now.
31    o pkg/obcs:
32      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
33        see verification/seaice_obcs/input.seaiceSponge for example application.
34      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
35        index setting by master-thread. This fix multi-threads Pb in previous modifs.
36    o pkg/layers :
37      - add diagnostics to pkg/layers
38      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
39        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
40    o pkg/generic_advdiff/gad_implicit_r.F :
41      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
42    o pkg/seaice/seaice_growth.F:
43      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
44    o pkg/obcs:
45      - change default setting of OBCS_UVICE_OLD from defined to undef;
46      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
47        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
48      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
49      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
50        with Southern & Western OB at a tile edge (at least in a simple set-up).
51    o pkg/obcs:
52      - change settings of OB index in case OB coincides with tile edge (shared by
53        2 tiles), so that common OB location is registered by both tiles (instead of
54        only 1). However, for Southern and Western OB, index value = 0 is not
55        recognized as valid OB index (=default null value) and needs to be fixed.
56      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
57      - new parameter "OB_indexNone" for null index value (for now, still zero)
58        to replace hard-coded null index value of zero.
59    o pkg/exch2:
60      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
61        always check buffer-size (but outside the loop); move checking for valid
62        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
63        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
64    o pkg/ctrl (pack & unpack):
65      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
66        (locally defined) for different variables (+ remove the variable-specific
67        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
68        (to be extended to other local file names in ctrl.h).
69    o pkg/flt:
70      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
71    o pkg/mdsio:
72      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
73    o tools/genmake2:
74      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
75        (added by Alistair in version 1.51 for building without make depend);
76      - remove Header files list (H_SRC_FILES) from the dependence of targets
77         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
78        place in version 1.23): this save going through staf when unrelated header
79        file has been modified.
80       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
81        "make depend" step, still need to do "make links" before "make adtaf".
82    o eesupp/src (+ few pkg src files) & genmake2:
83      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
84      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
85      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
86         upper/lower case ; account for space between "#" and undef/define)
87    o pkg/flt (with exch2):
88      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
89      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
90    
91    checkpoint63s (2012/09/05)
92    o pkg/ecco:
93      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
94      - add more relevant #ifdef ALLOW_SMOOTH ones.
95      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
96    o pkg/ctrl:
97      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
98        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
99      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
100        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
101        ctrlSmoothCorrel3D (new).
102        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
103      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
104      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
105        controls when useAtmWind, and vice versa.
106      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
107      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
108          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
109      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
110          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
111      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
112        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
113    o pkg/smooth:
114      - remove un-necessary includes.
115      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
116        Those CPP options were never defined, and not necessary.
117    o model/src:
118      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
119      - standard treatment of useSMOOTH.
120    o pkg/autodiff:
121      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
122        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
123    o pkg/exch2:
124      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
125        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
126      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
127        and tiles to process mapping.
128      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
129        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
130        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
131        from w2_eeboot.F to w2_readparms.F.
132    o eesupp/src:
133      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
134        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
135        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
136      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
137        is defined (remove condition on usingMPI) to match cases where MPI_INIT
138        has been called.
139      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
140      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
141        (so that on 1 proc, get same myPid independently of usingMPI)
142      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
143        useCubedSphereExchange with EXCH-1 (safer).
144      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
145    o pkg/ggl90:
146      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
147        used in ALLOW_GGL90_SMOOTH code.
148    o pkg/flt:
149      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
150        floats at the Southern end of the domain).
151    o eesupp/inc:
152      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
153        but not used (and not to be used) anywhere, just for documentation.
154    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
155      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
156        a) can damage previously written records in any other multi-record files.
157        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
158    o tools/genmake2:
159      - define variable MAKE within Makefile and use it in place of 'make';
160      - update AD_CONFIG.h (if needed) before building any of the executable
161        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
162        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
163      - always print usual warning comment 'this file is automatically generated'
164        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
165    o pkg/cheapaml:
166      - updated to correspond to the code used in accepted paper (Nico Wienders).
167    o pkg/exf:
168        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
169        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
170        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
171    o pkg/exf, autodiff, ctrl, ecco and seaice:
172        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
173    o pkg/ctrl, ecco:
174        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
175        Depending on useAtmWind, one is inactive, and the other is active (see
176        exf_getffields.F/exf_getsurfacefluxes.F).
177    o tools/genmake2:
178      - improve error msg when failing in 2nd test of check_for_broken_Ff
179      - fix option '-makefile' short-name (-mf according to genmake2 -help)
180      - source local config file "genmake_local" just after processing the genmake2
181        command arguments (previously done before processing arg).
182    o pkg/grdchk:
183      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
184        to this routine from cost_final has been dropped in g_cost_final)
185      - improve printed information (more explicit msg, no longer using "print *,"
186         fix fcpertminus printed value).
187    o model/src:
188      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
189        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
190        this prevents getting cost-funct reset in adinitialise_varia recomputations.
191    o pkg/dic:
192      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
193        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
194    o pkg/grdchk:
195      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
196      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
197    o pkg/autodiff/ctrl/grdchk :
198      - attempt to sort out what works and what does not,
199        with regard to I/O, and to warn/stop accordingly.
200    o pkg/grdchk:
201      - attempt to fix grdchk in the case of useSingleCpuIO.
202      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
203       statements were moved from grdchk_main.F and into
204       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
205      - a global sum is applied to record numbers icvrec/layer
206       out of grdchk_loc so that they be passed to I/O routines.
207    o pkg/smooth:
208      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
209        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
210    o verification/testreport:
211      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
212      - can also use compressed (gzip) reference output file;
213      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
214        to be easier to collect by testreport.
215      - update existing TLM output (half out-of-date by more than 3 yrs).
216      - report NETCDF & LAPACK settings (from genmake2) in output dir.
217      - report run-time in each individual summary (previously only for AD test);
218        for TLM test, add also TAF version.
219      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
220    
221    checkpoint63r (2012/08/15)
222    o tools/genmake2:
223      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
224    o pkg/ecco/ecco_cost_final.F :
225      - fix fc print statements (to stdout and costfunction0000) so
226        that the printed value is always after the global sum.
227    o pkg/seaice/seaice_dynsolver.F :
228      - fix ice strength assymptote at SEAICE_area_max<1
229        (no change for the standard case of SEAICE_area_max=1)
230    o some cleaning:
231      - pkg source files: ensure that all *.F files from each pkg included the
232        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
233        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
234        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
235        includes;
236      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
237      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
238        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
239        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
240      - update option-file CPP_OPTIONS.h of all AD experiments:
241        * no longer include PACKAGES_CONFIG.h ;
242        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
243        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
244          including ECCO_CPPOPTIONS.h).
245    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
246      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
247        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
248        not necessary accurate).
249      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
250        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
251        deliberately break compilation (a remainder that it needs to be customized)
252      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
253      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
254      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
255    o tools/genamke2:
256      - check for lapack.
257    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
258      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
259        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
260        from both packages.
261      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
262      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
263      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
264        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
265    o pkg/cost : add comments to explain special and/or untested setups.
266    o pkg/exf:
267      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
268        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
269    o verification/*/code_ad:
270      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
271      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
272      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
273        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
274    o pkg/seaice :
275      - added possibility to change ice strength/PRESS0 relationship to
276        HEFF, according to the following run time parameters
277        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
278        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
279        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
280    o pkg/ggl90 :
281      - added run time flag mxlSurfFlag to include the code that ensure
282        mixing between first and second level (previously included as a comment)
283    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
284      - add test of newly added dumpAdByRec=T option where
285        we write all records to one file per variable.
286    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
287      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
288        to check that this code is ok with taf and compiles in adjoint.
289    o pkg/autodiff :
290      - added run time param dumpAdByRec : ad dump format switch.
291        If true then write all records to one file per variable.
292        Else write one file per record (remains the default).
293      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
294    o pkg/seaice:
295     - Added SEAICEuseTILT run time switch : if set to
296       false then omit the tilt term in seaice dynamics.
297     - Fix free drift calculation.
298    o pkg/shelfice:
299      When initializing SHELFICEDragQuadratic, set default to be
300      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
301      but retain option to set it independently
302      (inconsistenty spotted by Veronique Dansereau)
303    o eesupp/inc:
304      - in EEPARAMS.h, add real-type constant for some frequently used simple number
305         (0,1,2,1/2), with name explicitly referring to RS/RL type.
306    o model/src:
307      - move balancing of relaxation terms to new S/R balance_relax.F.
308    o pkg/autodiff:
309      re-write active I/O high-level (control) S/R:
310      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
311      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
312      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
313        MDS_READ/WRITE_FIELD); change loops to multi-threads.
314      - update and merge active_file_control_slice.flow into active_file_control.flow
315      - update the calls in lower level S/R (active_file.F, active_file_g.F and
316        active_file_ad.F) keeping the argument list and function unchanged.
317      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
318        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
319      - new low-level active I/O routines, one for each type (RL/RS), for active var
320        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
321        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
322        right type.
323    o autodiff and RS=real*4:
324      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
325        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
326      - change argument type of 3-D mask argument to _RS to match type in the call
327        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
328    o pkg/thsice:
329      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
330      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
331        fresh-water flux: uniform correction or proportional to local precip.
332    o pkg/ctrl:
333      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
334      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
335                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
336      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
337    
338    checkpoint63q (2012/07/30)
339    o pkg/autodiff:
340      note about monitor and snap-shot of ad-variables:
341      a) need to apply ADEXCH before monitor or output of ad-vars to include
342       overlap contributions (was done for adjDump but missing for monitor).
343      b) since ADEXCH implies adding overlap values to interior array, machine
344       truncation error is expected when adding an ADEXCH call in the middle of
345       the time-stepping (although mathematically identical).
346      modifs:
347      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
348        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
349      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
350        apply ADEXCH before monitor or snap-shot of ad-variables:
351           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
352      - implement new method (copy+adexch) for snap-shot and monitor of main model
353        ad-vars (initially not used by default -> output unchanged).
354      - change default (set to 2) to use new method and update few output_adm.txt
355        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
356        and both tutorial_tracer_adjsens tests).
357      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
358        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
359    o pkg/ctrl:
360      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
361      generic control variables via
362      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
363      Only required customization should be S/R ctrl_map_ini_genarr.F
364      (routine in repository contains example)
365    o pkg/exf:
366      - fix and refine checking of surface-relaxation setting when using EXF
367    o verification (adjoint exp):
368      - reduce length of simulation by half for experiment global_ocean.cs32x15
369        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
370    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
371      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
372        of KE that can occur with aggressive optimization
373      + put quadratic bottom drag calculation in separated loops (only done if
374        using bottomDragQuadratic)
375    o model/src: CG2D_NSA
376      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
377         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
378      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
379         change cg2d residual target to be expressed in Wunits (=> do not normalise
380         RHS ; this fix global_max Pb with TAF); update output.
381    o verification/tutorial_tracer_adjsens:
382       improve parameter consistency (and get rid of warnings):
383       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
384       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
385       - use staggerTimeStep (for stability) in som81; use default rotation period.
386    o pkg/exch2:
387      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
388        reset to 0 = 1 long line in X)
389    o pkg/mdsio:
390      - fix reading of dimensions from meta file for large-size domain
391    o model/src:
392      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
393      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
394        Cubed-Sphere Exch with CS-corners inside the domain;
395        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
396        globalArea and to set hasWetCSCorners.
397      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
398        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
399      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
400        useCDscheme and useCubedSphereExchange).
401    o pkg/seaice/seaice_growth.F :
402      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
403        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
404        when the previous code was not correct.
405      - in all cases diagnoze the boundary condition mismatch to SIaaflux
406      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
407        that term to QNET (essentially to set the melt/freeze water to 0degC).
408        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
409    o verification/global_ocean.cs32x15/input.seaice :
410      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
411      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
412      - update results (output.seaice.txt) accordingly.
413    o verification/lab_sea/input/data.seaice :
414      - remove SEAICEheatConsFix, which is now be tested
415        in global_ocean.cs32x15. The presently coded fix
416        is only consistent with real fresh water + nlfs.
417      - update results (output.txt) accordingly.
418    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
419    o AD_CONFIG.h file:
420      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
421      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
422        add it explicitly in each fortran src file where it is needed.
423        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
424        thus introducing potentially wrong dependency; therefore, better to include
425        it only where it's really needed, and after any other included OPTIONS file
426        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
427        or ALLOW_TANGENTLINEAR_RUN).
428    
429    checkpoint63p (2012/07/06)
430    o pkg/autodiff:
431      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
432      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
433        which are now read from new parameter file "data.autodiff" (inAdExact
434        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
435      - add file "data.autodiff" in all verification/*/input_ad/ directories.
436      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
437        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
438    o verification/tutorial_tracer_adjsens/
439      - add extra sub-verification which uses "SOM" advection scheme
440        (2nd Order-Moment Advection Scheme, Prather Limiter) with
441          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
442        and in data:
443          multiDimAdvection=.TRUE.,
444          tempAdvScheme=81,
445          saltAdvScheme=81,
446    o model/src:
447      - introduce ALLOW_BALANCE_RELAX which allow the removal
448       of the global mean of relaxation terms by setting
449       balanceThetaClimRelax and balanceSaltClimRelax
450      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
451       This case is now treated appropriately in seaice_growth.F
452    o pkg/seaice:
453      - do balanceEmPmR and balanceQnet based on the net fluxes
454        (SItflux) that enter the ocean+ice system rather than QNET
455        and EMPMR. Works best in real fresh water.
456      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
457        out of the diagnotics bloc, and stored in global arrays.
458    
459    checkpoint63o (2012/06/29)
460    o vertical mixing schemes:
461      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
462      - replace computation of density (in Function STATE1, opps_calc.F) by a call
463        to S/R FIND_RHO_SCALAR
464      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
465        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
466        affects output (vermix.ggl90) at truncation level.
467    o testreport:
468      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
469        (nSx,nSy) for the number of threads (from eedata.mth)
470    o model/src:
471      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
472        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
473    o verification/tutorial_tracer_adjsens/
474      - compile with ALLOW_CG2D_NSA
475      - run with nonlinFreeSurf=3
476      - update reference output_adm.txt
477    o tools/genmake2:
478      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
479        refine usePROFILES switching off (only when NetCDF is not available).
480    o verification (atmospheric set-up):
481      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
482    o pkg/profiles : refine profiles and files handling.
483    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
484    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
485      - changes to use model/src/the_main_loop.F rather than the ecco version
486        in ecco type adjoint runs.
487    o model/src:
488      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
489      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
490      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
491  o model/src:  o model/src:
492    - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);    - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
493      update output of test experiment bottom_ctrl_5x5.      update output of test experiment bottom_ctrl_5x5.
494  o pkg/generic_advdiff:  o pkg/generic_advdiff:
495    - implement vertical bi-harmonic diffusion (for now, only for T & S and    - implement vertical bi-harmonic diffusion (for now, only for T & S and
