4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/cheapaml:
8      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
9        to load new forcing fields.
10      - add missing "_d 0" where it's needed; + some editing (improve indentation).
11      - remove switch to "-r8" compiler option (no longer needed) in verification
12        cheapAML_box, keep same output (small trucation error differences).
13    o verification/offline_exf_seaice:
14      - add thermodynamics only test.
15    o verification/cheapAML_box:
16      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
17        keep same output (same 14 digits for cg2d).
18      - switch on "-r8" compiler option (some numerical values are missing
19        the "_d 0") and update output (only 6 digits for cg2d were preserved).
20    
21    checkpoint64b (2012/12/24)
22    o pkg/cheapaml:
23      - remove un-used variables (Qnet,EmPmR) from pickup files.
24      - store tendency of advected variables into cheapaml pickup file
25        and fix the AB-2 restart.
26    o verification/offline_exf_seaice and lab_sea adjoint:
27      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
28      - switch to 4 time steps in offline, consistent with lab_sea.
29      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
30      - update results after change of experiment seaice.
31    o pkg/seaice:
32      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
33        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
34        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
35        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
36    o model/src:
37      - add run-time parameter to select CG2D solver minimum-residual solution
38        (in case of a poor convergence).
39    o pkg/seaice/seaice_lsr.F
40      - move calculation of matrix coefficients into new
41        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
42        file; the main purpose of this change is to be able to reuse the code
43        in S/R SEAICE_PRECONDITIONER
44      - modify the computation of the residual so that the mass of sea-ice
45        is not used twice; this simplifies the calculations, but since
46        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
47        not tested in testreport---this does not affect the testreport results.
48    o verification/seaice_obcs:
49      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
50        verification/lab_sea/input.salt_plume; changes results/output.txt*
51    o model/src:
52      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
53    o pkg/seaice:
54      - improve description of parameters in seaice_fgmres.F and start
55        cleaning up the code
56      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
57        second argument
58      - add a metric based on grid cell area to SEAICE_SCALPROD; update
59        results of offline_exf_seaice.dyn_jfnk
60      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
61    o pkg/aim_v23:
62      - fix an other bug in dissipation heating (grid-cell area was missing).
63    o model/src + pkg/seaice:
64      - add global (multi-tile) linear solver for pair of tri-diagonal system
65        along X and Y lines, respectively for U and V component.
66        Note: 1) MPI and cube-exchange not yet coded.
67            2) probably not accurate for poorly conditioned / large size problem.
68      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
69        default: not compiled and not used.
70    o pkg/seaice:
71      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
72        introduce bi/bj loops and use global_sum_tile_rl instead of
73        mpi_allreduce in seaice_fgmres.F
74      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
75      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
76      - add a verification experiment for JFNK in offline_exf_seaice
77    o verification:
78      - change (for now, only fwd test) offline_exf_seaice experiment:
79        use a re-entrant channel with idealized coastline (trapezoidal shape)
80        at southern boundary to explore seaice dynamics and thermodynamics
81        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
82        secondary test (input.thsice) use thermodynamics only with SST relaxation.
83      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
84    o pkg/exf:
85      - disable "sstExtrapol" when Nr=1
86    o verification:
87      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
88        to test pkg/cheapaml.
89    o pkg/aim_v23 & pkg/shap_filt:
90      - fix dissipation heating (erroneous gravity multiplication factor).
91    o pkg/seaice:
92      - remove unused field pressPre from jfnk solver
93      - rename two subroutines in seaice_preconditioner.F
94    o eesupp/src:
95       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
96    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
97       - remove wrong parts of the rhs and the lhs (were in there
98         because I did not understand the concept of this preconditioner)
99       - add an exchange between u- and v-sweep. This increases communication
100         by a factor of two but improves the convergence of jfnk. Ideally,
101         one would like the u- and v-sweep to be independent. So far within
102         undocumented ifdefs
103       - reorganize the extra computations for printing the residuals
104    o tools/genmake2:
105      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
106        since it's not necessary (and was preventing to use MNC in some cases).
107    
108    checkpoint64a (2012/11/16)
109    o pkg/autodiff:
110      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
111        autodiff_readparms.F no longer depends on calling order (within
112        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
113        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
114        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
115    o pkg/obcs:
116      - adding tidal velocity forcing capability to obcs
117        for usage example, see verification/seaice_obcs/input.tides
118    o pkg/seaice:
119      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
120        SEAICE_LSRrelaxU/V
121      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
122    o pkg/aim_v23:
123      - implement heating from friction (bottom friction and stratospheric drag).
124    o pkg/shap_filt:
125      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
126        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
127    o model/src:
128      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
129        time-constant addMass field from file (addMassFile);
130      - support for heating due to friction (and Kinetic Energy dissipation):
131        add option, run-time switch and 3-D field array + support code ; each pkg
132        or S/R can add heating contribution (if there is a sink of KE); the sum is
133        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
134    o pkg/seaice:
135      - complete merge of ITD code into seaice_growth.F
136        from MITgcm_contrib/torge/itd/code/
137        no verification so far, but Torge Martin tested
138        "1-D test case and Beaufort set up;
139        deliver okay results after 1 model year."
140      - complete merge of SEAICE_SIZE.h into all relevant routines
141      - move computation of eta at Z-points into calc_viscosities
142        + introduce global field etaZ
143        + add different methods for computing etaZ, for now the old
144          method (simple averages of eta to Z-points) is hardwired
145        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
146          seaice_preconditioner
147      - simplify computations for SEAICE_ZETA_SMOOTHREG
148      - seaice_preconditioner:
149        + replace one remaining press by pressLoc (mistake)
150        + adjust printing of residuals
151      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
152        + add (SEAICE.h) and rename some counters (initiliased in
153          seaice_init_fixed.F)
154        + add _BEGIN/END_MASTER (myThid)  around print statements
155        + print total number of iterations and failures over SEAICE_monFreq
156          interval to STDOUT
157      - move control over output-messages by fgmres to seaice_jfnk to save
158        some operations
159      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
160        in order to make restarts with sol .ne. zero (fgmres with restarts)
161        (seaice_jfnk.F, seaice_fgmres.F)
162      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
163        a serious convergence problem when open boundaries are involved
164    o pkg/ggl90: fix computation of control volumes for the case of
165      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
166      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
167    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
168    o pkg/autodiff
169      - Add inAdMode switch for SEAICEuseDYNAMICS:
170        SEAICEuseDYNAMICSinAdMode
171        (extend logic in ADAUTODIFF_INADMODE_SET)
172    o pkg/seaice
173      - Step 1 of merging ice-thickness distribution (ITD) code from
174        MITgcm_contrib/torge/itd/ (author: Torge Martin)
175        The code implements concept laid out in Thorndike et al. (1975);
176        code is enabled via CPP flag SEAICE_ITD
177        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
178        code is not complete yet!!
179      - SEAICE_SIZE.h now included in almost all seaice routines
180    o verification (using seaice):
181      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
182        global_ocean.cs32x15.seaice ; update results.
183      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
184      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
185        offline_exf_seaice (previously compiling B-grid).
186    o pkg/exf:
187      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
188        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
189        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
190    o pkg/layers (adjust changes from Sept 19):
191      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
192        this allows to remove "layers_maxNum" dimension from all layers arrays.
193    o pkg/layers (adjust changes from Sept 19):
194      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
195      - snap-shot extended to all type of layers (not just the 1rst type);
196      - remove layers variables when corresponding CPP option is undef.
197    o pkg/layers:
198      - rename pkg/layers variable and add new output (layer exist & un-weighted
199        velocity in layer)
200    o pkg/seaice:
201      - simplify (?) ocean-drag coefficent computations by using
202        the same routine in all three solvers (saves some code lines)
203      - remove global fields DRAGA and DRAGS from C-grid code and
204        declare them locally in lsr.F (the only place where they are
205        still used)
206      - update AD output of lab_sea.evp (very sensitive anyway).
207    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
208      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
209      and SEAICEuseJFNK=.true. A few things to note:
210      - involves a FGMRES, that is parallel but very inefficient,
211        because of many scalar products (global sums) in the Gram-Schmidt
212        orthogonalization method. Needs to be replaced. Original code
213        from J.-F. Lemieux
214      - preconditioner for FGMRES is a stripped down version of LSOR
215      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
216        preconditioner. For the preconditioner, the default is set to 10.
217      - Jacobian times vector is computed with finite differences
218      - marginally related to JFNK-solver: add a smooth regularization for
219        zeta with tanh that will improve convergence (Lemieux and Tremblay,
220        2009) for any implicit solver (not implemented for EVP because EVP
221        does not need this regularization in the first place). Define
222        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
223    o eesupp/src:
224      - check in genmake2 that intrinsic S/R flush is available.
225      - add S/R to flush IO unit (if intrinsic S/R flush is available)
226      - flush standard & error msg unit before MPI termination
227      - if debugMode, flush IO unit after printing msg
228    o pkg/ctrl:
229      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
230        to ctrl_set_unpack_xyz.
231    
232    checkpoint64 (2012/10/09)
233    o pkg/shelfice
234      - in mom_fluxform.F, mom_vecinv.F:
235        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
236        Bug fix KappaRU -> KappaRV
237        does not change verification/isomip but may change other setups
238        (presumably constant KappaRU=KappaRV)
239      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
240    o pkg/obcs:
241      - fixed some indexing bugs in obcs_seaice_sponge.F
242      - added obcs relaxation subroutines for HSALT and HSNOW
243      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
244    o pkg/seaice:
245      - add "multicategory" parameterization for snow in analogy to ice,
246        default is off for now.
247    o pkg/obcs:
248      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
249        see verification/seaice_obcs/input.seaiceSponge for example application.
250      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
251        index setting by master-thread. This fix multi-threads Pb in previous modifs.
252    o pkg/layers :
253      - add diagnostics to pkg/layers
254      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
255        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
256    o pkg/generic_advdiff/gad_implicit_r.F :
257      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
258    o pkg/seaice/seaice_growth.F:
259      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
260    o pkg/obcs:
261      - change default setting of OBCS_UVICE_OLD from defined to undef;
262      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
263        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
264      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
265      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
266        with Southern & Western OB at a tile edge (at least in a simple set-up).
267    o pkg/obcs:
268      - change settings of OB index in case OB coincides with tile edge (shared by
269        2 tiles), so that common OB location is registered by both tiles (instead of
270        only 1). However, for Southern and Western OB, index value = 0 is not
271        recognized as valid OB index (=default null value) and needs to be fixed.
272      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
273      - new parameter "OB_indexNone" for null index value (for now, still zero)
274        to replace hard-coded null index value of zero.
275    o pkg/exch2:
276      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
277        always check buffer-size (but outside the loop); move checking for valid
278        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
279        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
280    o pkg/ctrl (pack & unpack):
281      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
282        (locally defined) for different variables (+ remove the variable-specific
283        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
284        (to be extended to other local file names in ctrl.h).
285    o pkg/flt:
286      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
287    o pkg/mdsio:
288      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
289    o tools/genmake2:
290      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
291        (added by Alistair in version 1.51 for building without make depend);
292      - remove Header files list (H_SRC_FILES) from the dependence of targets
293         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
294        place in version 1.23): this save going through staf when unrelated header
295        file has been modified.
296       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
297        "make depend" step, still need to do "make links" before "make adtaf".
298    o eesupp/src (+ few pkg src files) & genmake2:
299      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
300      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
301      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
302         upper/lower case ; account for space between "#" and undef/define)
303    o pkg/flt (with exch2):
304      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
305      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
306    
307    checkpoint63s (2012/09/05)
308    o pkg/ecco:
309      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
310      - add more relevant #ifdef ALLOW_SMOOTH ones.
311      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
312    o pkg/ctrl:
313      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
314        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
315      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
316        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
317        ctrlSmoothCorrel3D (new).
318        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
319      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
320      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
321        controls when useAtmWind, and vice versa.
322      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
323      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
324          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
325      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
326          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
327      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
328        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
329    o pkg/smooth:
330      - remove un-necessary includes.
331      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
332        Those CPP options were never defined, and not necessary.
333    o model/src:
334      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
335      - standard treatment of useSMOOTH.
336    o pkg/autodiff:
337      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
338        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
339    o pkg/exch2:
340      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
341        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
342      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
343        and tiles to process mapping.
344      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
345        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
346        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
347        from w2_eeboot.F to w2_readparms.F.
348    o eesupp/src:
349      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
350        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
351        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
352      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
353        is defined (remove condition on usingMPI) to match cases where MPI_INIT
354        has been called.
355      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
356      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
357        (so that on 1 proc, get same myPid independently of usingMPI)
358      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
359        useCubedSphereExchange with EXCH-1 (safer).
360      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
361    o pkg/ggl90:
362      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
363        used in ALLOW_GGL90_SMOOTH code.
364    o pkg/flt:
365      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
366        floats at the Southern end of the domain).
367    o eesupp/inc:
368      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
369        but not used (and not to be used) anywhere, just for documentation.
370    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
371      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
372        a) can damage previously written records in any other multi-record files.
373        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
374    o tools/genmake2:
375      - define variable MAKE within Makefile and use it in place of 'make';
376      - update AD_CONFIG.h (if needed) before building any of the executable
377        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
378        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
379      - always print usual warning comment 'this file is automatically generated'
380        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
381    o pkg/cheapaml:
382      - updated to correspond to the code used in accepted paper (Nico Wienders).
383    o pkg/exf:
384        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
385        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
386        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
387    o pkg/exf, autodiff, ctrl, ecco and seaice:
388        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
389    o pkg/ctrl, ecco:
390        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
391        Depending on useAtmWind, one is inactive, and the other is active (see
392        exf_getffields.F/exf_getsurfacefluxes.F).
393    o tools/genmake2:
394      - improve error msg when failing in 2nd test of check_for_broken_Ff
395      - fix option '-makefile' short-name (-mf according to genmake2 -help)
396      - source local config file "genmake_local" just after processing the genmake2
397        command arguments (previously done before processing arg).
398    o pkg/grdchk:
399      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
400        to this routine from cost_final has been dropped in g_cost_final)
401      - improve printed information (more explicit msg, no longer using "print *,"
402         fix fcpertminus printed value).
403    o model/src:
404      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
405        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
406        this prevents getting cost-funct reset in adinitialise_varia recomputations.
407    o pkg/dic:
408      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
409        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
410    o pkg/grdchk:
411      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
412      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
413    o pkg/autodiff/ctrl/grdchk :
414      - attempt to sort out what works and what does not,
415        with regard to I/O, and to warn/stop accordingly.
416    o pkg/grdchk:
417      - attempt to fix grdchk in the case of useSingleCpuIO.
418      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
419       statements were moved from grdchk_main.F and into
420       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
421      - a global sum is applied to record numbers icvrec/layer
422       out of grdchk_loc so that they be passed to I/O routines.
423    o pkg/smooth:
424      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
425        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
426    o verification/testreport:
427      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
428      - can also use compressed (gzip) reference output file;
429      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
430        to be easier to collect by testreport.
431      - update existing TLM output (half out-of-date by more than 3 yrs).
432      - report NETCDF & LAPACK settings (from genmake2) in output dir.
433      - report run-time in each individual summary (previously only for AD test);
434        for TLM test, add also TAF version.
435      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
436    
437    checkpoint63r (2012/08/15)
438    o tools/genmake2:
439      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
440    o pkg/ecco/ecco_cost_final.F :
441      - fix fc print statements (to stdout and costfunction0000) so
442        that the printed value is always after the global sum.
443    o pkg/seaice/seaice_dynsolver.F :
444      - fix ice strength assymptote at SEAICE_area_max<1
445        (no change for the standard case of SEAICE_area_max=1)
446    o some cleaning:
447      - pkg source files: ensure that all *.F files from each pkg included the
448        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
449        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
450        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
451        includes;
452      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
453      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
454        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
455        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
456      - update option-file CPP_OPTIONS.h of all AD experiments:
457        * no longer include PACKAGES_CONFIG.h ;
458        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
459        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
460          including ECCO_CPPOPTIONS.h).
461    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
462      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
463        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
464        not necessary accurate).
465      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
466        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
467        deliberately break compilation (a remainder that it needs to be customized)
468      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
469      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
470      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
471    o tools/genamke2:
472      - check for lapack.
473    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
474      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
475        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
476        from both packages.
477      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
478      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
479      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
480        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
481    o pkg/cost : add comments to explain special and/or untested setups.
482    o pkg/exf:
483      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
484        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
485    o verification/*/code_ad:
486      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
487      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
488      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
489        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
490    o pkg/seaice :
491      - added possibility to change ice strength/PRESS0 relationship to
492        HEFF, according to the following run time parameters
493        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
494        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
495        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
496    o pkg/ggl90 :
497      - added run time flag mxlSurfFlag to include the code that ensure
498        mixing between first and second level (previously included as a comment)
499    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
500      - add test of newly added dumpAdByRec=T option where
501        we write all records to one file per variable.
502    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
503      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
504        to check that this code is ok with taf and compiles in adjoint.
505    o pkg/autodiff :
506      - added run time param dumpAdByRec : ad dump format switch.
507        If true then write all records to one file per variable.
508        Else write one file per record (remains the default).
509      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
510    o pkg/seaice:
511     - Added SEAICEuseTILT run time switch : if set to
512       false then omit the tilt term in seaice dynamics.
513     - Fix free drift calculation.
514    o pkg/shelfice:
515      When initializing SHELFICEDragQuadratic, set default to be
516      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
517      but retain option to set it independently
518      (inconsistenty spotted by Veronique Dansereau)
519    o eesupp/inc:
520      - in EEPARAMS.h, add real-type constant for some frequently used simple number
521         (0,1,2,1/2), with name explicitly referring to RS/RL type.
522    o model/src:
523      - move balancing of relaxation terms to new S/R balance_relax.F.
524    o pkg/autodiff:
525      re-write active I/O high-level (control) S/R:
526      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
527      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
528      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
529        MDS_READ/WRITE_FIELD); change loops to multi-threads.
530      - update and merge active_file_control_slice.flow into active_file_control.flow
531      - update the calls in lower level S/R (active_file.F, active_file_g.F and
532        active_file_ad.F) keeping the argument list and function unchanged.
533      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
534        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
535      - new low-level active I/O routines, one for each type (RL/RS), for active var
536        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
537        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
538        right type.
539    o autodiff and RS=real*4:
540      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
541        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
542      - change argument type of 3-D mask argument to _RS to match type in the call
543        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
544    o pkg/thsice:
545      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
546      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
547        fresh-water flux: uniform correction or proportional to local precip.
548    o pkg/ctrl:
549      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
550      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
551                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
552      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
553    
554    checkpoint63q (2012/07/30)
555    o pkg/autodiff:
556      note about monitor and snap-shot of ad-variables:
557      a) need to apply ADEXCH before monitor or output of ad-vars to include
558       overlap contributions (was done for adjDump but missing for monitor).
559      b) since ADEXCH implies adding overlap values to interior array, machine
560       truncation error is expected when adding an ADEXCH call in the middle of
561       the time-stepping (although mathematically identical).
562      modifs:
563      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
564        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
565      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
566        apply ADEXCH before monitor or snap-shot of ad-variables:
567           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
568      - implement new method (copy+adexch) for snap-shot and monitor of main model
569        ad-vars (initially not used by default -> output unchanged).
570      - change default (set to 2) to use new method and update few output_adm.txt
571        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
572        and both tutorial_tracer_adjsens tests).
573      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
574        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
575    o pkg/ctrl:
576      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
577      generic control variables via
578      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
579      Only required customization should be S/R ctrl_map_ini_genarr.F
580      (routine in repository contains example)
581    o pkg/exf:
582      - fix and refine checking of surface-relaxation setting when using EXF
583    o verification (adjoint exp):
584      - reduce length of simulation by half for experiment global_ocean.cs32x15
585        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
586    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
587      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
588        of KE that can occur with aggressive optimization
589      + put quadratic bottom drag calculation in separated loops (only done if
590        using bottomDragQuadratic)
591    o model/src: CG2D_NSA
592      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
593         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
594      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
595         change cg2d residual target to be expressed in Wunits (=> do not normalise
596         RHS ; this fix global_max Pb with TAF); update output.
597    o verification/tutorial_tracer_adjsens:
598       improve parameter consistency (and get rid of warnings):
599       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
600       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
601       - use staggerTimeStep (for stability) in som81; use default rotation period.
602    o pkg/exch2:
603      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
604        reset to 0 = 1 long line in X)
605    o pkg/mdsio:
606      - fix reading of dimensions from meta file for large-size domain
607    o model/src:
608      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
609      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
610        Cubed-Sphere Exch with CS-corners inside the domain;
611        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
612        globalArea and to set hasWetCSCorners.
613      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
614        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
615      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
616        useCDscheme and useCubedSphereExchange).
617    o pkg/seaice/seaice_growth.F :
618      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
619        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
620        when the previous code was not correct.
621      - in all cases diagnoze the boundary condition mismatch to SIaaflux
622      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
623        that term to QNET (essentially to set the melt/freeze water to 0degC).
624        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
625    o verification/global_ocean.cs32x15/input.seaice :
626      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
627      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
628      - update results (output.seaice.txt) accordingly.
629    o verification/lab_sea/input/data.seaice :
630      - remove SEAICEheatConsFix, which is now be tested
631        in global_ocean.cs32x15. The presently coded fix
632        is only consistent with real fresh water + nlfs.
633      - update results (output.txt) accordingly.
634    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
635    o AD_CONFIG.h file:
636      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
637      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
638        add it explicitly in each fortran src file where it is needed.
639        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
640        thus introducing potentially wrong dependency; therefore, better to include
641        it only where it's really needed, and after any other included OPTIONS file
642        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
643        or ALLOW_TANGENTLINEAR_RUN).
644    
645    checkpoint63p (2012/07/06)
646    o pkg/autodiff:
647      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
648      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
649        which are now read from new parameter file "data.autodiff" (inAdExact
650        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
651      - add file "data.autodiff" in all verification/*/input_ad/ directories.
652      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
653        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
654    o verification/tutorial_tracer_adjsens/
655      - add extra sub-verification which uses "SOM" advection scheme
656        (2nd Order-Moment Advection Scheme, Prather Limiter) with
657          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
658        and in data:
659          multiDimAdvection=.TRUE.,
660          tempAdvScheme=81,
661          saltAdvScheme=81,
662    o model/src:
663      - introduce ALLOW_BALANCE_RELAX which allow the removal
664       of the global mean of relaxation terms by setting
665       balanceThetaClimRelax and balanceSaltClimRelax
666      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
667       This case is now treated appropriately in seaice_growth.F
668    o pkg/seaice:
669      - do balanceEmPmR and balanceQnet based on the net fluxes
670        (SItflux) that enter the ocean+ice system rather than QNET
671        and EMPMR. Works best in real fresh water.
672      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
673        out of the diagnotics bloc, and stored in global arrays.
674    
675    checkpoint63o (2012/06/29)
676    o vertical mixing schemes:
677      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
678      - replace computation of density (in Function STATE1, opps_calc.F) by a call
679        to S/R FIND_RHO_SCALAR
680      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
681        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
682        affects output (vermix.ggl90) at truncation level.
683    o testreport:
684      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
685        (nSx,nSy) for the number of threads (from eedata.mth)
686    o model/src:
687      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
688        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
689    o verification/tutorial_tracer_adjsens/
690      - compile with ALLOW_CG2D_NSA
691      - run with nonlinFreeSurf=3
692      - update reference output_adm.txt
693    o tools/genmake2:
694      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
695        refine usePROFILES switching off (only when NetCDF is not available).
696    o verification (atmospheric set-up):
697      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
698    o pkg/profiles : refine profiles and files handling.
699    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
700    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
701      - changes to use model/src/the_main_loop.F rather than the ecco version
702        in ecco type adjoint runs.
703    o model/src:
704      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
705      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
706      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
707    o model/src:
708      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
709        update output of test experiment bottom_ctrl_5x5.
710    o pkg/generic_advdiff:
711      - implement vertical bi-harmonic diffusion (for now, only for T & S and
712        only explicitly).
713    o verification/bottom_ctrl_5x5/
714      update reference output (results changed quite some time ago,
715      not sure when; but new reference results look ok in terms of grdchk)
716    o verification/1D_ocean_ice_column/
717      For verification purposes, the exact adjoint rather than an approx.
718      should be used (e.g., to comare against F.D. or TLM).
719      removed autodiff_inadmode*_ad.F routines in code_ad/
720      Update results/ accordingly.
721    o pkg/cal:
722      - change cal_getdate.F so that output date is function of input time only
723        (less ambiguous, not mixed up with input iteration number).
724      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
725    o pkg/diagnostics:
726      - implement calendarDumps also for stats-diags
727      - implement calendarDumps also for snap-shot output (negative freq)
728      - for now, ignores calendarDumps if non-zero phase-lag.
729    
730    checkpoint63n (2012/06/04)
731    o model/src:
732      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
733        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
734      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
735        similar to calc_r_star.F); update results of experiment internal_wave and
736        tutorial_global_oce_in_p (affected @ truncation level).
737    o pkg/shelfice:
738      - add parameterisation of advective-diffusive flux into the ice shelf
739        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
740      - simply eps3/3a computation
741    o eesupp:
742     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
743       between tiles, just fill-in edges assuming locally periodic subdomain) and
744       add corresponding exchange subroutines (EXCH0);
745     - new CG-solver version (_EX0) for disconnected-tiles special case.
746    o model/src (CG-solvers):
747     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
748       (similar final residual output and max-Iter number as with standard version);
749     - allows to store and use lowest-residual solution (standard & _SR versions);
750     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
751     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
752    o eesup/src:
753     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
754       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
755    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
756    
757    checkpoint63m (2012/04/27)
758    o pkg/shelfice:
759     - account for partical cells in surface level below ice-shelf for hydrostatic
760       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
761    o ad test experiments:
762     - update and rename to "ad_optfile.local" local AD-optfile specific to a
763       particular adjoint verification experiment (in verification/*/code_ad/)
764    o pkg/seaice & pkg/exf:
765     - Part two of ECCO-CLIVAR code merges.
766       Completes merge of seaice area relax. code.
767       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
768       to be set in EXF_OPTIONS.h since this pkg controls its I/O
769       (and avoids second CPP option in SEAICE_OPTIONS.h)
770     - change default value of costIceStart & costIceEnd to a valid date.
771     - add snowPrecip to HSNOW in seaice_growth
772    o pkg/ptracers:
773     - move ptracers summary and setup check into separated S/R ; add a check for
774       valid PTRACERS_Iter0 value (error+stop or just warning).
775    o pkg/cal (+ pkg/ecco):
776     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
777       as input; and for AD, unless both are not differentiable (e.g., k index)).
778    o model/src:
779     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
780       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
781       temporary set to usingZCoords value (to be changed to F when using shelfice).
782     - hydrostatic pressure: implement partial cell near the surface also for
783       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
784       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
785    o pkg/ctrl/ctrl_init.F:
786     - add a formal parameter to s/r ctrl_init_rec to print
787       xx_$(ctrl_valiable)_file for easier debugging
788     - move call of cal_* routines into the if-block where they are really
789       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
790       to specify a startdate
791    o pkg/seaice:
792     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
793       global_ocean.cs32x15/code versions).
794     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
795       verification experiment global_ocean.cs32x15.seaice and update results.
796    o pkg/exf:
797     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
798       (according to useExfYearlyFields).
799    o pkg/cal:
800     - move calendar setting & summary (previously in cal_readparams.F) into new
801       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
802       length of the simulation is set (after SET_PARMS call); This is an attempt
803       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
804     - For safety: keep a record of pkg/cal parameter settings status
805               to allow to STOP if one pkg/cal S/R is called too early.
806     - add a stop in all basic pkg/cal subroutines if called before setting is done.
807     - modify cal_getdate.F: stop when nothing was returned;
808       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
809       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
810    
811    checkpoint63l (2012/04/04)
812    o pkg/bbl:
813      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
814        update global_with_exf output.yearly.txt file.
815    o pkg/cal:
816      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
817      - remove 2 unsused and very short (1 line only) functions ;
818      - remove unsused subroutines from AD-Diff list.
819    o model/src:
820      - start to implement clean wait to stop in initialization S/R (config_check.F,
821         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
822    o folowing PRINT_MESSAGE changes:
823      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
824    o pkg/bbl:
825      - modification so it can work with z*
826      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
827      - global_with_exf/input.yearly verification; changes output.yearly.txt
828    o eesupp/src:
829      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
830        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
831      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
832        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
833      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
834      - when using MPI, always set usingMPI=T ; set default accordingly and stop
835        if not consistent.
836      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
837        argument is zero (in case called within single-thread section).
838    o pkg/fizhi:
839        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
840        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
841    o pkg/exch2:
842      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
843        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
844      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
845        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
846        with bad ones coming from a not-yet-updated halo.
847        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
848    o pkg/frazil:
849        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
850        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
851    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
852    o verification/lab_sea
853      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
854      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
855      * nTimeSteps 3 -> 4
856      * changed reference output accordingly
857    o pkg/ctrl:
858      * fix ctrl_get_gen for xx_sst, xx_sss
859    o pkg/fizhi:
860      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
861        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
862      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
863        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
864        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
865    o pkg/gmredi:
866      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
867    o pkg/fizhi:
868      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
869        (old)aces open64 tuv test.
870    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
871    o pkg/mom_vecinv:
872      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
873        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
874        with non-lin free-surf).
875    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
876      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
877      some compilers (gfortran 4.6.0 on MacOS)
878    o momentum:
879      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
880        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
881        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
882    
883    checkpoint63k (2012/03/17)
884    o model/src:
885       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
886         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
887       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
888         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
889    o model/src: solve_*diagonal.F
890       - replace division with multiplication by inverse (similar to original version)
891         update output of AD exp. global_ocean.90x40x15.
892       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
893         to enable the use of the vectorized & differentiable solve_tridiagonal.F
894       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
895         vertical advection (to get solve_tridiagonal tested in AD mode).
896    o pkg/seaice: ECCO-CLIVAR merge:
897      1. seaice AREA relaxation
898         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
899         * runtime flag: SEAICE_tauAreaObsRelax
900      2. modified global mean cost imbalance code: CPP option
901          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
902    o another iteration on solve_*diagonal.F
903       Make choices independent of AUTODIFF
904       Default will be the adjoinable vectorized version.
905       Alternative choices are:
906       * non-adjoinable original version with low memory footprint:
907         #define SOLVE_DIAGONAL_LOWMEMORY
908       * still adjoinable but does not vectorize (k as inner-most loop):
909         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
910    o testreport
911     - add option to use a home made wrapper around "make"
912     - remove MITGCM_IEEE env. variable (no longer active)
913    o pkg/shelfice
914     - improve computation of friction velocity for velocity dependent
915       exchange coefficients: include velocities into SHELFICEBoundaryLayer
916       block to average velocities vertically
917     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
918    o Modify diagonal solvers, now three versions (upon request):
919      #ifndef SOLVE_DIAGONAL_AUTODIFF
920        1. default version (dating back a while ago)
921      #else /* def SOLVE_DIAGONAL_AUTODIFF */
922      # ifdef SOLVE_DIAGONAL_KINNER
923        2. adjoinable version with k-innermost loop (G. Forget)
924      # else
925        3. adjoinable vectorized version of 2.
926      # endif
927      #endif /* SOLVE_DIAGONAL_AUTODIFF */
928      All flags are currently set within routines, but could/should be moved to CPP-options.
929      Array bounds for 1. are as before, for 2.,3. cover the entire domain
930      (could be changed for 1. too).
931    o verification/lab_sea (fwd):
932      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
933        use 7 categories (except hb87), new solve4temp params (except salt_plume),
934        constant salinity (=4) or variable salinity (salt_plume) done through
935        SItracer.
936    o pkg/seaice:
937      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
938      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
939         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
940        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
941        SEAICE_freeze got retired) but already better than previously with
942        SEAICE_freeze=123456.7 deg.C;
943      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
944        (safer multi-threaded setting); always set SEAICEuseEVP;
945      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
946        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
947        stop if multiple specifications for the same coeff; make sure default
948        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
949    o pkg/obcs:
950      - allow to switch to upwind 1rst order advection scheme for the advective
951        flux computation at the open-boundary; disabled for adjoint built.
952    o pkg/ptracers:
953      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
954      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
955      - add parameter to decide when to start a tracer; use internal flag to
956        know which tracer to step-forward; switch this internal flag at the top
957        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
958        for adjoint built.
959    o pkg/seaice:
960      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
961      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
962      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
963    o pkg/ecco:
964      - fix writing of output file DiagnosCost_ClimSalt/Theta
965        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
966    o pkg/seaice:
967      - add missing initialisation of COR_ICE array in dynsolver.F
968      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
969        compiled either way, and is tested in all exps (multidim was only tested
970        in lab_sea ad before).
971      - cosmetic change to prepare for future addition of ITD. no change to results.
972        no defaults change.
973      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
974      - by lack of adequate verification experiments, I further used custom versions
975        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
976        should be correct.
977      - avoid recomputations in ad.
978    o array initialisation in adjoint mode:
979      1) pkg/mom_common/mom_calc_ke.F:
980        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
981        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
982        part this initialisation is gone, resulting in Floating Point Exception
983        (caught by open64 compiler with debug option).
984      2) model/src/convective_weights.F
985        set output convectCount over the full array range (instead of doing
986        an update): this fix a similar issue when called within recomputation (adjoint)
987        which could by-pass the initialisation (normally done in the caller S/R).
988    o pkg/seaice:
989      - final version of turbulent flux params, as agreed at MIT ice meet:
990           SEAICE_mcPheePiston (default is ~ 0.000875)
991           SEAICE_mcPheeTaper (default is 0.)
992           SEAICE_frazilFrac (defualt is 1.)
993           SEAICE_mcPheeStepFunc (default is false)
994      - changes results at trunction error level
995      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
996    o added pkg/frazil:
997      - see frazil_description.tex for details
998      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
999    o pkg/shelfice/shelfice_thermodynamics.F
1000      - fix exponents for velocity dependent exchange coefficients: change
1001        from 2/3(=0) to 0.66666666666666667
1002      - move computation of velocity dependent exchange coefficients into
1003        separate loop, so that it applies to both thermodynamics
1004      - move some divisions by constants out of loops
1005    
1006    checkpoint63j (2012/02/16)
1007    o pkg/seaice:
1008      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
1009      - SItracer:  added run time params, and allow coupling to ocn salinity.
1010    o pkg/seaice: remove (almost) all divisions by constants within loops
1011      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
1012      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
1013      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
1014      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
1015    o pkg/seaice :
1016      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
1017        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
1018      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
1019      - add permanent SItflux diag that corresponds to TFLUX but includes
1020        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
1021      - allow activation/testing of a fix for suspected missing term in
1022        ocn-ice heat budget (to be confirmed). To test this, you want to
1023        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
1024        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
1025      - no change in results, fwd or ad.
1026    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
1027      - switch to variable freezing point.
1028           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
1029      - bug fix : the sublimation term that was missing is now activated.
1030           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
1031      - bug fix : flooding sign term for SIsal0.NE.0.
1032           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
1033    o pkg/seaice:
1034      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
1035        is now the default, and the old default constant freezing point is recovered
1036        with SEAICE_tempFrz0    = -1.96,
1037             SEAICE_dTempFrz_dS = 0.,
1038      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
1039      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
1040      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
1041        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
1042      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
1043        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
1044      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
1045        seaice_growth r149 for legacy branch (no results change).
1046      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
1047        from I. Fenty).
1048      - results did not change except for global_ocean.cs32x15, mostly due to the
1049        switch to variable freezing point (see above item for detail).
1050    o pkg/thsice:
1051      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
1052        seawater freezing in thsice_calc_thickn (not used).
1053    o pkg/seaice: turbulent flux term specification via run time params.
1054      - replace CPP switches with run time switches to facilitate testing
1055      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
1056                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
1057      - added runtime parameter : SEAICEturbFluxFormula
1058      - move Mcphee constants to SEAICE_PARAMS.h
1059      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
1060                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
1061                 remove seaice_summary call (moved to seaice_init_fixed)
1062      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
1063        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
1064      - seaice_summary.F : add missing report of read turbulent flux term set up
1065                           and SITRACER.
1066      - seaice_check.F : check range; inform and stop if retired CPPs are used
1067                         (incl. SEAICE_AGE).
1068      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
1069             CPP switch, same computation as before for the different options.
1070      - change results at the truncation level.
1071    o pkg/seaice:
1072      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
1073        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
1074        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
1075      - update verification/*/input*/data.seaice:
1076        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
1077        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
1078        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
1079        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
1080    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
1081      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
1082        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
1083        difference in results only due to machine truncation.
1084      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
1085        MaykutPolySatVap; keep MIN_LWDOWN.
1086      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
1087      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
1088        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
1089    o pkg/salt_plume:
1090      - isolate saltPlumeFlux array exch into a specific S/R called from
1091        do_oceanic_phys.F
1092      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
1093    o verification:
1094      - move untested set-up to MITgcm_contrib/verification_other.
1095    o pkg/seaice:
1096      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
1097    o pkg/seaice:
1098      - seaice_solve4temp.F (keeping results unchanged):
1099        * add 2 future run-time params to select which saturation vapor pressure
1100          formula is used and how post-iteration fluxes are set.
1101          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
1102        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
1103          the linearized expression to stay consistent with tsurf finding.
1104      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
1105        can be < 0.
1106    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
1107      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
1108        conductive heat flux F_c , and add it explicitly when updating tsurf as
1109        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
1110        so that now F_ia has a consistent meaning through the entire routine.
1111        This causes differences at truncation level: update output of fwd exp.
1112        global_ocean.cs32x15.seaice.
1113    o pkg/seaice:
1114      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
1115        of arrays, sign/direction of fluxes; no effect on results.
1116      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
1117        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
1118        note: this should have been done before changing celsius2K default.
1119      - to keep results unchanged, add back old value of celsius2K in verification
1120        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
1121      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
1122        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
1123        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
1124        freezing temp is consistent with value in seaice_growth.F ; this causes
1125        differences at machine truncation level: update lab_sea AD output (3/4).
1126    o pkg/seaice:
1127      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
1128        and climsst/sss even when using seaice (to prevent calculation that might
1129        use SST on land); does not affect any verification exp.
1130      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
1131        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
1132    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
1133      over land (non-legacy code)
1134    o vectorize salt_plume package:
1135      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
1136      - this code computes plumebk everywhere (also over land), thus requires
1137        code to avoid divisions by zero and catch the case of kLev=Nr.
1138      - efficiency of salt_plume_frac is still sub-optimal
1139    o tools (genmake2):
1140      - fix makefile NAME specification (option: -makefile NAME) by adding
1141        "-f $MAKEFILE" in few places where it was missing including makedepend
1142        command (contribution from Paul).
1143    
1144    checkpoint63i (2012/01/24)
1145    o model/src:
1146      - add factorized versions of some EOS code to find_rho.F,
1147        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
1148    o model/src:
1149      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
1150      - change default celsius2K from 273.16 to 273.15
1151      - to keep results unchanged, add back old value of celsius2K in verification
1152        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
1153         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
1154    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
1155      to make TAF generate vectorizable code
1156    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
1157       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
1158       have flags that do this more efficiently.
1159    o pkg/diagnostics/diagstats_calc.F
1160      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
1161    o pkg/obcs (with exch2):
1162      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
1163        and remove code (in obcs_readparms.F) which was based on EXCH of indices
1164        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
1165    o pkg/exf and seaice exp:
1166      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
1167        so that switching off area & heff advection flags does not affect results.
1168      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
1169      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
1170        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
1171        results of verification experiments: 1D_ocean_ice_column(fwd),
1172        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
1173        and offline_exf_seaice (all 4).
1174    o pkg/seaice:
1175      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
1176        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
1177      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
1178        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
1179        not multi-dim advection;
1180      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
1181        SHORTWAVE_HEATING #undef.
1182    o optim: make Makefile more robust (?)
1183    o pkg/obcs:
1184      * fix treatment of obcs_read_pickup for TAF
1185    o pkg/shelfice:
1186      * add missing initialisation of num_shifwflx
1187      * new adjoint verification exp. for isomip
1188      * change Prandtl and Schmidt numbers from generic formulations
1189        (in terms of model diffus. and visc.) to separate runtime
1190        parameters, with Holland and Jenkins (1999) default values.
1191    o pkg/exf (interpolation):
1192      - extended input field (2 rows) near the N & S poles:
1193        * fill in with the symetric value (when even Nb of data in longitude)
1194        * add average value at the poles only for scalar quantities ; for vector
1195          component interpolation, skip the averaging and keep duplicated values,
1196          unless the 2 components have same location (uvInterp=T) in which case
1197          interpolate the 2 components together using S/R EXF_INTERP_UV.
1198      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
1199        together: this allows to account properly for local orientation when
1200        averaging at N & S pole.
1201      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
1202        exf-interpolation near N & S poles. Undef by default.
1203      - add debug check/print on 1rst iter if debugLevel >=2.
1204    o pkg/exf:
1205      - change masking flags definition (no longer "parameter"), put them in
1206        common block and set them in S/R EXF_INIT_FIXED.
1207      - change recognized masking flag from s,u,v to c,w,s since the mask
1208        to use (maskC,W,S) depends on position on model grid and has little to
1209        do with scalar/vector difference; fix masking if using P-coordinates.
1210      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
1211        and update results of exp. global_with_exf (x2).
1212      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
1213    o pkg/obcs
1214      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
1215    o pkg/exf (interpolation):
1216      - assume periodicity in X only if input field cover full longitude range.
1217      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
1218        and should vectorise).
1219      - fix input lat of the 2 added row (in case we provide N.pole data).
1220    
1221    checkpoint63h (2011/12/30)
1222    o pkg/seaice:
1223      - change declaration of UVM from _RL to _RS in order to get B-grid
1224        uIce,vIce monitor when _RS = real*4
1225    o pkg/offline:
1226      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
1227      - compute vertical velocity if not read from file (switch on exactConserv
1228        & staggerTimeStep);
1229      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
1230    o verification:
1231      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
1232        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
1233        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
1234      - update output of exp. global_ocean.cs32x15.viscA4 after changing
1235        grid-file angles (used here for coriolis-3d);
1236      - remove (or gzip) few files not needed to run fizhi-cs experiments.
1237    o pkg/exf (vector interpolation):
1238      - rotate vector component toward local grid-axis orientation using grid-angles
1239        (stored in GRID.h) instead of locally computed rotation angle; keep old code
1240        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
1241    o pkg/seaice:
1242      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
1243        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
1244    o pkg/PKG_OPTIONS.h files:
1245      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
1246        outside of the #ifdef ALLOW_THISPKG / #endif block.
1247      - update verification/*/code/PKG_OPTIONS.h files.
1248    o add a verification experiment (offline_exf_seaice/input.seaice) that test
1249      the B-grid LSOR solver
1250    o pkg/seaice: sort out emissivity and long wave radiation step 2:
1251      - add emissivity for snow and ice as new run-time parameters
1252        (unfortunately) that default to the corresponding exf values; this
1253        changes results in most verification experiments so that for backward
1254        compatibility these parameter have to be set explicitly to inconsistent
1255        values (ugly);
1256      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
1257        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
1258        until we agree how to handle this bug properly
1259    o pkg/exf (interpolation):
1260      - add a set of run-time param ({inputfield}_interpMethod), one for
1261        each interpolated input field, to select the interpolation method
1262        with a value of zero switching off the interpolation;
1263      - print interpolation parameters to standard output;
1264      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
1265        (to use instead runoff_interpMethod=0 in data.exf).
1266      - simplify default setting of interpolation parameters (for all fields,
1267        set position to match model grid cell-center position, leading to trivial
1268        interpolation in case of regular Lat-Lon grid) and fix for the case of
1269        non-uniform delY.
1270    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
1271       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
1272       this factor is absolutely required, because the lw exitance (= out-going
1273       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
1274       where the reflectivity rho = 1-emissivity for conservation reasons. Once
1275       this is established, we can remove the CPP-Flag (if we want to).
1276    o pkg/seaice:
1277      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
1278        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
1279      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
1280        what the name implies (and not emissivity*BoltzmannConstant), this means
1281        the old default value of 5.5e-8 now means
1282        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
1283        S/R exf_readparms
1284      - FV-discretization of the B-grid LSOR solver, turn on with
1285        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
1286        of the calling routine dynsolver, so that B and C-grid code look a
1287        little more alike.
1288      - fix index bugs in ostres.F (B-grid code)
1289    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
1290    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
1291      default for SEAICE_emissivity, if useEXF; requires setting a wrong
1292      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
1293      backward compatiblity
1294    o model/src: use sigmaR in calc_ivdc
1295    
1296    checkpoint63g (2011/12/16)
1297    o pkg/seaice/seaice_growth.F:
1298      fix heat conservation of the coupled ocean-seaice system.
1299      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
1300      solid vs liquid water treatment is resolved via QNET.
1301    o pkg/seaice/seaice_growth.F:
1302      add missing term for sublimation in saltFlux, which was breaking conservation.
1303    o pkg/seaice/seaice_model.F:
1304      Remove this patholigical case treatment in evolution branch,
1305      where it is un-necessary and breaks conservation.
1306      Update global_ocean.cs32x15/results accordingly for
1307      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
1308    o model/src:
1309      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
1310      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
1311    o pkg/obcs:
1312      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
1313      tendency for temperature and salinity that is then applied to update
1314      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
1315      horizontal advection and diffusion contributions on the boundary (in
1316      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
1317      removing the mask in S/R timestep_tracer. The advantage of this approach is
1318      that the updated tracer values include contributions from the surface
1319      forcing and vertical diffusion.
1320      This modification changes exp4.stevens because of vertical diffusion.
1321    o model/src:
1322      change non-curvilinear grid setting to also work with exch2 + blank tiles:
1323      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
1324        face dimensions.
1325      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
1326        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
1327        and INI_SPHERICAL_POLAR_GRID.
1328      change test-experiment global_ocean.90x40x15:
1329      - split the domain in many more tiles (9x4 tiles of 10x10 each);
1330      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
1331      - update results of both test (std & dwnslp).
1332    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
1333       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
1334    o model/src:
1335      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
1336        and fix initialisation when using sigma-coords.
1337    o model/src:
1338     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
1339       to their current value at the beginning of forward_step.F": add a new run-time
1340       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
1341     - set doResetHFactors=T in the following test exp:
1342        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
1343        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
1344        and tutorial_global_oce_in_p (nonLinFS in p)
1345    o pkg/ecco
1346      - added IES cost term
1347    o verification/advect_xz
1348      - scale down the depth by 1/100 (from 200 km to just 2.km)
1349      - add secondary test using divergent flow, r-star and implicit vertical advection.
1350      - add note (check_conserve_TS.txt) and matlab script to check global
1351        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
1352    o pkg/rbcs:
1353      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
1354    o pkg/obcs (Stevens BCs):
1355      - fix various problems in the phase speed computations of the Stevens
1356        boundary conditions:
1357        - sign error for western and southern boundaries,
1358        - time tendencies were underestimated by factor of dTracerLev and some just
1359          zero (for multidim advection schemes) -> now estimate time tendencies
1360          from difference between previous (n) time level and the one before (n-1);
1361          this requires storing a field per tracer per boundary, also in the pickup
1362          files.
1363        - replace deltaTmom in cflMer/Zon computation with dTracerLev
1364        - set default phase velocity to cflMer/Zon
1365      - update verification experiment exp4.stevens
1366  o pkg/generic_advdiff (implicit_r):  o pkg/generic_advdiff (implicit_r):
1367    - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf    - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
1368      (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);      (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
