4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - add run-time parameter to select CG2D solver minimum-residual solution
9        (in case of a poor convergence).
10    o pkg/seaice/seaice_lsr.F
11      - move calculation of matrix coefficients into new
12        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
13        file; the main purpose of this change is to be able to reuse the code
14        in S/R SEAICE_PRECONDITIONER
15      - modify the computation of the residual so that the mass of sea-ice
16        is not used twice; this simplyfies the calculations, but since
17        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
18        not tested in testreport---this does not affect the testreport results.
19    o verification/seaice_obcs:
20      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
21        verification/lab_sea/input.salt_plume; changes results/output.txt*
22    o model/src:
23      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
24    o pkg/seaice:
25      - improve description of parameters in seaice_fgmres.F and start
26        cleaning up the code
27      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
28        second argument
29      - add a metric based on grid cell area to SEAICE_SCALPROD; update
30        results of offline_exf_seaice.dyn_jfnk
31      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
32    o pkg/aim_v23:
33      - fix an other bug in dissipation heating (grid-cell area was missing).
34    o model/src + pkg/seaice:
35      - add global (multi-tile) linear solver for pair of tri-diagonal system
36        along X and Y lines, respectively for U and V component.
37        Note: 1) MPI and cube-exchange not yet coded.
38            2) probably not accurate for poorly conditioned / large size problem.
39      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
40        default: not compiled and not used.
41    o pkg/seaice:
42      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
43        introduce bi/bj loops and use global_sum_tile_rl instead of
44        mpi_allreduce in seaice_fgmres.F
45      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
46      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
47      - add a verification experiment for JFNK in offline_exf_seaice
48    o verification:
49      - change (for now, only fwd test) offline_exf_seaice experiment:
50        use a re-entrant channel with idealized costline (trapezoidal shape)
51        at southern boundary to explore seaice dynamics and thermodynamics
52        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
53        secondary test (input.thsice) use thermodynamics only with SST relaxation.
54      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
55    o pkg/exf:
56      - disable "sstExtrapol" when Nr=1
57    o verification:
58      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
59        to test pkg/cheapaml.
60    o pkg/aim_v23 & pkg/shap_filt:
61      - fix dissipation heating (erroneous gravity multiplication factor).
62    o pkg/seaice:
63      - remove unused field pressPre from jfnk solver
64      - rename two subroutines in seaice_preconditioner.F
65    o eesupp/src:
66       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
67    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
68       - remove wrong parts of the rhs and the lhs (were in there
69         because I did not understand the concept of this preconditioner)
70       - add an exchange between u- and v-sweep. This increases communication
71         by a factor of two but improves the convergence of jfnk. Ideally,
72         one would like the u- and v-sweep to be independent. So far within
73         undocumented ifdefs
74       - reorganize the extra computations for printing the residuals
75    o tools/genmake2:
76      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
77        since it's not necessary (and was preventing to use MNC in some cases).
78    
79    checkpoint64a (2012/11/16)
80    o pkg/autodiff:
81      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
82        autodiff_readparms.F no longer depends on calling order (within
83        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
84        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
85        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
86    o pkg/obcs:
87      - adding tidal velocity forcing capability to obcs
88        for usage example, see verification/seaice_obcs/input.tides
89    o pkg/seaice:
90      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
91        SEAICE_LSRrelaxU/V
92      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
93    o pkg/aim_v23:
94      - implement heating from friction (bottom friction and stratospheric drag).
95    o pkg/shap_filt:
96      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
97        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
98    o model/src:
99      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
100        time-constant addMass field from file (addMassFile);
101      - support for heating due to friction (and Kinetic Energy dissipation):
102        add option, run-time switch and 3-D field array + support code ; each pkg
103        or S/R can add heating contribution (if there is a sink of KE); the sum is
104        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
105    o pkg/seaice:
106      - complete merge of ITD code into seaice_growth.F
107        from MITgcm_contrib/torge/itd/code/
108        no verification so far, but Torge Martin tested
109        "1-D test case and Beaufort set up;
110        deliver okay results after 1 model year."
111      - complete merge of SEAICE_SIZE.h into all relevant routines
112      - move computation of eta at Z-points into calc_viscosities
113        + introduce global field etaZ
114        + add different methods for computing etaZ, for now the old
115          method (simple averages of eta to Z-points) is hardwired
116        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
117          seaice_preconditioner
118      - simplify computations for SEAICE_ZETA_SMOOTHREG
119      - seaice_preconditioner:
120        + replace one remaining press by pressLoc (mistake)
121        + adjust printing of residuals
122      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
123        + add (SEAICE.h) and rename some counters (initiliased in
124          seaice_init_fixed.F)
125        + add _BEGIN/END_MASTER (myThid)  around print statements
126        + print total number of iterations and failures over SEAICE_monFreq
127          interval to STDOUT
128      - move control over output-messages by fgmres to seaice_jfnk to save
129        some operations
130      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
131        in order to make restarts with sol .ne. zero (fgmres with restarts)
132        (seaice_jfnk.F, seaice_fgmres.F)
133      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
134        a serious convergence problem when open boundaries are involved
135    o pkg/ggl90: fix computation of control volumes for the case of
136      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
137      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
138    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
139    o pkg/autodiff
140      - Add inAdMode switch for SEAICEuseDYNAMICS:
141        SEAICEuseDYNAMICSinAdMode
142        (extend logic in ADAUTODIFF_INADMODE_SET)
143    o pkg/seaice
144      - Step 1 of merging ice-thickness distribution (ITD) code from
145        MITgcm_contrib/torge/itd/ (author: Torge Martin)
146        The code implements concept laid out in Thorndike et al. (1975);
147        code is enabled via CPP flag SEAICE_ITD
148        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
149        code is not complete yet!!
150      - SEAICE_SIZE.h now included in almost all seaice routines
151    o verification (using seaice):
152      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
153        global_ocean.cs32x15.seaice ; update results.
154      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
155      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
156        offline_exf_seaice (previously compiling B-grid).
157    o pkg/exf:
158      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
159        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
160        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
161    o pkg/layers (adjust changes from Sept 19):
162      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
163        this allows to remove "layers_maxNum" dimension from all layers arrays.
164    o pkg/layers (adjust changes from Sept 19):
165      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
166      - snap-shot extended to all type of layers (not just the 1rst type);
167      - remove layers variables when corresponding CPP option is undef.
168    o pkg/layers:
169      - rename pkg/layers variable and add new output (layer exist & un-weighted
170        velocity in layer)
171    o pkg/seaice:
172      - simplify (?) ocean-drag coefficent computations by using
173        the same routine in all three solvers (saves some code lines)
174      - remove global fields DRAGA and DRAGS from C-grid code and
175        declare them locally in lsr.F (the only place where they are
176        still used)
177      - update AD output of lab_sea.evp (very sensitive anyway).
178    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
179      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
180      and SEAICEuseJFNK=.true. A few things to note:
181      - involves a FGMRES, that is parallel but very inefficient,
182        because of many scalar products (global sums) in the Gram-Schmidt
183        orthogonalization method. Needs to be replaced. Original code
184        from J.-F. Lemieux
185      - preconditioner for FGMRES is a stripped down version of LSOR
186      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
187        preconditioner. For the preconditioner, the default is set to 10.
188      - Jacobian times vector is computed with finite differences
189      - marginally related to JFNK-solver: add a smooth regularization for
190        zeta with tanh that will improve convergence (Lemieux and Tremblay,
191        2009) for any implicit solver (not implemented for EVP because EVP
192        does not need this regularization in the first place). Define
193        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
194    o eesupp/src:
195      - check in genmake2 that intrinsic S/R flush is available.
196      - add S/R to flush IO unit (if intrinsic S/R flush is available)
197      - flush standard & error msg unit before MPI termination
198      - if debugMode, flush IO unit after printing msg
199    o pkg/ctrl:
200      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
201        to ctrl_set_unpack_xyz.
202    
203    checkpoint64 (2012/10/09)
204    o pkg/shelfice
205      - in mom_fluxform.F, mom_vecinv.F:
206        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
207        Bug fix KappaRU -> KappaRV
208        does not change verification/isomip but may change other setups
209        (presumably constant KappaRU=KappaRV)
210      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
211    o pkg/obcs:
212      - fixed some indexing bugs in obcs_seaice_sponge.F
213      - added obcs relaxation subroutines for HSALT and HSNOW
214      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
215    o pkg/seaice:
216      - add "multicategory" parameterization for snow in analogy to ice,
217        default is off for now.
218    o pkg/obcs:
219      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
220        see verification/seaice_obcs/input.seaiceSponge for example application.
221      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
222        index setting by master-thread. This fix multi-threads Pb in previous modifs.
223    o pkg/layers :
224      - add diagnostics to pkg/layers
225      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
226        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
227    o pkg/generic_advdiff/gad_implicit_r.F :
228      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
229    o pkg/seaice/seaice_growth.F:
230      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
231    o pkg/obcs:
232      - change default setting of OBCS_UVICE_OLD from defined to undef;
233      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
234        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
235      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
236      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
237        with Southern & Western OB at a tile edge (at least in a simple set-up).
238    o pkg/obcs:
239      - change settings of OB index in case OB coincides with tile edge (shared by
240        2 tiles), so that common OB location is registered by both tiles (instead of
241        only 1). However, for Southern and Western OB, index value = 0 is not
242        recognized as valid OB index (=default null value) and needs to be fixed.
243      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
244      - new parameter "OB_indexNone" for null index value (for now, still zero)
245        to replace hard-coded null index value of zero.
246    o pkg/exch2:
247      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
248        always check buffer-size (but outside the loop); move checking for valid
249        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
250        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
251    o pkg/ctrl (pack & unpack):
252      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
253        (locally defined) for different variables (+ remove the variable-specific
254        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
255        (to be extended to other local file names in ctrl.h).
256    o pkg/flt:
257      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
258    o pkg/mdsio:
259      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
260    o tools/genmake2:
261      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
262        (added by Alistair in version 1.51 for building without make depend);
263      - remove Header files list (H_SRC_FILES) from the dependence of targets
264         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
265        place in version 1.23): this save going through staf when unrelated header
266        file has been modified.
267       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
268        "make depend" step, still need to do "make links" before "make adtaf".
269    o eesupp/src (+ few pkg src files) & genmake2:
270      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
271      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
272      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
273         upper/lower case ; account for space between "#" and undef/define)
274    o pkg/flt (with exch2):
275      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
276      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
277    
278    checkpoint63s (2012/09/05)
279    o pkg/ecco:
280      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
281      - add more relevant #ifdef ALLOW_SMOOTH ones.
282      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
283    o pkg/ctrl:
284      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
285        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
286      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
287        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
288        ctrlSmoothCorrel3D (new).
289        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
290      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
291      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
292        controls when useAtmWind, and vice versa.
293      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
294      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
295          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
296      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
297          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
298      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
299        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
300    o pkg/smooth:
301      - remove un-necessary includes.
302      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
303        Those CPP options were never defined, and not necessary.
304    o model/src:
305      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
306      - standard treatment of useSMOOTH.
307    o pkg/autodiff:
308      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
309        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
310    o pkg/exch2:
311      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
312        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
313      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
314        and tiles to process mapping.
315      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
316        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
317        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
318        from w2_eeboot.F to w2_readparms.F.
319    o eesupp/src:
320      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
321        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
322        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
323      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
324        is defined (remove condition on usingMPI) to match cases where MPI_INIT
325        has been called.
326      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
327      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
328        (so that on 1 proc, get same myPid independently of usingMPI)
329      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
330        useCubedSphereExchange with EXCH-1 (safer).
331      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
332    o pkg/ggl90:
333      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
334        used in ALLOW_GGL90_SMOOTH code.
335    o pkg/flt:
336      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
337        floats at the Southern end of the domain).
338    o eesupp/inc:
339      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
340        but not used (and not to be used) anywhere, just for documentation.
341    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
342      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
343        a) can damage previously written records in any other multi-record files.
344        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
345    o tools/genmake2:
346      - define variable MAKE within Makefile and use it in place of 'make';
347      - update AD_CONFIG.h (if needed) before building any of the executable
348        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
349        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
350      - always print usual warning comment 'this file is automatically generated'
351        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
352    o pkg/cheapaml:
353      - updated to correspond to the code used in accepted paper (Nico Wienders).
354    o pkg/exf:
355        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
356        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
357        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
358    o pkg/exf, autodiff, ctrl, ecco and seaice:
359        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
360    o pkg/ctrl, ecco:
361        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
362        Depending on useAtmWind, one is inactive, and the other is active (see
363        exf_getffields.F/exf_getsurfacefluxes.F).
364    o tools/genmake2:
365      - improve error msg when failing in 2nd test of check_for_broken_Ff
366      - fix option '-makefile' short-name (-mf according to genmake2 -help)
367      - source local config file "genmake_local" just after processing the genmake2
368        command arguments (previously done before processing arg).
369    o pkg/grdchk:
370      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
371        to this routine from cost_final has been dropped in g_cost_final)
372      - improve printed information (more explicit msg, no longer using "print *,"
373         fix fcpertminus printed value).
374    o model/src:
375      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
376        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
377        this prevents getting cost-funct reset in adinitialise_varia recomputations.
378    o pkg/dic:
379      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
380        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
381    o pkg/grdchk:
382      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
383      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
384    o pkg/autodiff/ctrl/grdchk :
385      - attempt to sort out what works and what does not,
386        with regard to I/O, and to warn/stop accordingly.
387    o pkg/grdchk:
388      - attempt to fix grdchk in the case of useSingleCpuIO.
389      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
390       statements were moved from grdchk_main.F and into
391       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
392      - a global sum is applied to record numbers icvrec/layer
393       out of grdchk_loc so that they be passed to I/O routines.
394    o pkg/smooth:
395      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
396        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
397    o verification/testreport:
398      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
399      - can also use compressed (gzip) reference output file;
400      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
401        to be easier to collect by testreport.
402      - update existing TLM output (half out-of-date by more than 3 yrs).
403      - report NETCDF & LAPACK settings (from genmake2) in output dir.
404      - report run-time in each individual summary (previously only for AD test);
405        for TLM test, add also TAF version.
406      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
407    
408    checkpoint63r (2012/08/15)
409    o tools/genmake2:
410      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
411    o pkg/ecco/ecco_cost_final.F :
412      - fix fc print statements (to stdout and costfunction0000) so
413        that the printed value is always after the global sum.
414    o pkg/seaice/seaice_dynsolver.F :
415      - fix ice strength assymptote at SEAICE_area_max<1
416        (no change for the standard case of SEAICE_area_max=1)
417    o some cleaning:
418      - pkg source files: ensure that all *.F files from each pkg included the
419        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
420        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
421        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
422        includes;
423      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
424      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
425        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
426        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
427      - update option-file CPP_OPTIONS.h of all AD experiments:
428        * no longer include PACKAGES_CONFIG.h ;
429        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
430        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
431          including ECCO_CPPOPTIONS.h).
432    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
433      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
434        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
435        not necessary accurate).
436      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
437        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
438        deliberately break compilation (a remainder that it needs to be customized)
439      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
440      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
441      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
442    o tools/genamke2:
443      - check for lapack.
444    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
445      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
446        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
447        from both packages.
448      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
449      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
450      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
451        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
452    o pkg/cost : add comments to explain special and/or untested setups.
453    o pkg/exf:
454      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
455        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
456    o verification/*/code_ad:
457      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
458      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
459      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
460        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
461    o pkg/seaice :
462      - added possibility to change ice strength/PRESS0 relationship to
463        HEFF, according to the following run time parameters
464        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
465        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
466        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
467    o pkg/ggl90 :
468      - added run time flag mxlSurfFlag to include the code that ensure
469        mixing between first and second level (previously included as a comment)
470    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
471      - add test of newly added dumpAdByRec=T option where
472        we write all records to one file per variable.
473    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
474      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
475        to check that this code is ok with taf and compiles in adjoint.
476    o pkg/autodiff :
477      - added run time param dumpAdByRec : ad dump format switch.
478        If true then write all records to one file per variable.
479        Else write one file per record (remains the default).
480      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
481    o pkg/seaice:
482     - Added SEAICEuseTILT run time switch : if set to
483       false then omit the tilt term in seaice dynamics.
484     - Fix free drift calculation.
485    o pkg/shelfice:
486      When initializing SHELFICEDragQuadratic, set default to be
487      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
488      but retain option to set it independently
489      (inconsistenty spotted by Veronique Dansereau)
490    o eesupp/inc:
491      - in EEPARAMS.h, add real-type constant for some frequently used simple number
492         (0,1,2,1/2), with name explicitly referring to RS/RL type.
493    o model/src:
494      - move balancing of relaxation terms to new S/R balance_relax.F.
495    o pkg/autodiff:
496      re-write active I/O high-level (control) S/R:
497      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
498      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
499      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
500        MDS_READ/WRITE_FIELD); change loops to multi-threads.
501      - update and merge active_file_control_slice.flow into active_file_control.flow
502      - update the calls in lower level S/R (active_file.F, active_file_g.F and
503        active_file_ad.F) keeping the argument list and function unchanged.
504      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
505        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
506      - new low-level active I/O routines, one for each type (RL/RS), for active var
507        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
508        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
509        right type.
510    o autodiff and RS=real*4:
511      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
512        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
513      - change argument type of 3-D mask argument to _RS to match type in the call
514        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
515    o pkg/thsice:
516      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
517      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
518        fresh-water flux: uniform correction or proportional to local precip.
519    o pkg/ctrl:
520      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
521      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
522                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
523      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
524    
525    checkpoint63q (2012/07/30)
526    o pkg/autodiff:
527      note about monitor and snap-shot of ad-variables:
528      a) need to apply ADEXCH before monitor or output of ad-vars to include
529       overlap contributions (was done for adjDump but missing for monitor).
530      b) since ADEXCH implies adding overlap values to interior array, machine
531       truncation error is expected when adding an ADEXCH call in the middle of
532       the time-stepping (although mathematically identical).
533      modifs:
534      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
535        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
536      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
537        apply ADEXCH before monitor or snap-shot of ad-variables:
538           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
539      - implement new method (copy+adexch) for snap-shot and monitor of main model
540        ad-vars (initially not used by default -> output unchanged).
541      - change default (set to 2) to use new method and update few output_adm.txt
542        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
543        and both tutorial_tracer_adjsens tests).
544      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
545        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
546    o pkg/ctrl:
547      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
548      generic control variables via
549      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
550      Only required customization should be S/R ctrl_map_ini_genarr.F
551      (routine in repository contains example)
552    o pkg/exf:
553      - fix and refine checking of surface-relaxation setting when using EXF
554    o verification (adjoint exp):
555      - reduce length of simulation by half for experiment global_ocean.cs32x15
556        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
557    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
558      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
559        of KE that can occur with aggressive optimization
560      + put quadratic bottom drag calculation in separated loops (only done if
561        using bottomDragQuadratic)
562    o model/src: CG2D_NSA
563      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
564         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
565      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
566         change cg2d residual target to be expressed in Wunits (=> do not normalise
567         RHS ; this fix global_max Pb with TAF); update output.
568    o verification/tutorial_tracer_adjsens:
569       improve parameter consistency (and get rid of warnings):
570       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
571       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
572       - use staggerTimeStep (for stability) in som81; use default rotation period.
573    o pkg/exch2:
574      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
575        reset to 0 = 1 long line in X)
576    o pkg/mdsio:
577      - fix reading of dimensions from meta file for large-size domain
578    o model/src:
579      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
580      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
581        Cubed-Sphere Exch with CS-corners inside the domain;
582        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
583        globalArea and to set hasWetCSCorners.
584      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
585        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
586      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
587        useCDscheme and useCubedSphereExchange).
588    o pkg/seaice/seaice_growth.F :
589      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
590        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
591        when the previous code was not correct.
592      - in all cases diagnoze the boundary condition mismatch to SIaaflux
593      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
594        that term to QNET (essentially to set the melt/freeze water to 0degC).
595        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
596    o verification/global_ocean.cs32x15/input.seaice :
597      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
598      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
599      - update results (output.seaice.txt) accordingly.
600    o verification/lab_sea/input/data.seaice :
601      - remove SEAICEheatConsFix, which is now be tested
602        in global_ocean.cs32x15. The presently coded fix
603        is only consistent with real fresh water + nlfs.
604      - update results (output.txt) accordingly.
605    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
606    o AD_CONFIG.h file:
607      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
608      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
609        add it explicitly in each fortran src file where it is needed.
610        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
611        thus introducing potentially wrong dependency; therefore, better to include
612        it only where it's really needed, and after any other included OPTIONS file
613        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
614        or ALLOW_TANGENTLINEAR_RUN).
615    
616    checkpoint63p (2012/07/06)
617    o pkg/autodiff:
618      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
619      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
620        which are now read from new parameter file "data.autodiff" (inAdExact
621        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
622      - add file "data.autodiff" in all verification/*/input_ad/ directories.
623      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
624        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
625    o verification/tutorial_tracer_adjsens/
626      - add extra sub-verification which uses "SOM" advection scheme
627        (2nd Order-Moment Advection Scheme, Prather Limiter) with
628          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
629        and in data:
630          multiDimAdvection=.TRUE.,
631          tempAdvScheme=81,
632          saltAdvScheme=81,
633    o model/src:
634      - introduce ALLOW_BALANCE_RELAX which allow the removal
635       of the global mean of relaxation terms by setting
636       balanceThetaClimRelax and balanceSaltClimRelax
637      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
638       This case is now treated appropriately in seaice_growth.F
639    o pkg/seaice:
640      - do balanceEmPmR and balanceQnet based on the net fluxes
641        (SItflux) that enter the ocean+ice system rather than QNET
642        and EMPMR. Works best in real fresh water.
643      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
644        out of the diagnotics bloc, and stored in global arrays.
645    
646    checkpoint63o (2012/06/29)
647    o vertical mixing schemes:
648      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
649      - replace computation of density (in Function STATE1, opps_calc.F) by a call
650        to S/R FIND_RHO_SCALAR
651      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
652        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
653        affects output (vermix.ggl90) at truncation level.
654    o testreport:
655      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
656        (nSx,nSy) for the number of threads (from eedata.mth)
657    o model/src:
658      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
659        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
660  o verification/tutorial_tracer_adjsens/  o verification/tutorial_tracer_adjsens/
661    - compile with ALLOW_CG2D_NSA    - compile with ALLOW_CG2D_NSA
662    - run with nonlinFreeSurf=3    - run with nonlinFreeSurf=3
