4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o pkg/exf:  o pkg/obcs:
8      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
9      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
10      in Interior region. No impact on solution but affects Velocity monitor stats.
11    o pkg/ptracers (adjoint)
12      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
13      tape file for each tracer
14    o model/inc/src and pkg/autodiff: add parameters that allow to turn
15      of parts of the adjoint code at run time. For now, there are only
16      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
17      parameters are set in data.pkg.
18      This is the lazy coward's version of doing this, but still useful for
19      debugging. In order to do it right, everything needs to be moved to
20      pkg/autodiff.
21    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
22      the end; this fixes the adjoint balancing code for open boundaries.
23    o pkg/ctrl:
24      - change behavior of xx_${varname}period to be analogous to exf-conventions:
25        xx_${varname}period =   0.,  means time-independent control part
26        xx_${varname}period = -12., means one-year-periodic monthly control part
27      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
28        clean up ctrl_init a little, remove unused variables
29      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
30      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
31    
32    checkpoint62u (2011/03/15)
33    o model/src:
34      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
35        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
36      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
37        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
38    o pkg/ctrl/obcs/ecco:
39      - remove obsolete, unused, and partially broken code:
40        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
41        ALLOW_CTRL_OBCS_BALANCE
42      - put a stop statement into ecco/cost_obcsvol.F, but also add
43        cost_obcsvol to ecco_ad_diff.list
44    o pkg/ecco: fix counting cost function contributions for obcs (code
45      by Matt M.) and diffkr for diagnostics
46    o pkg/ecco, pkg/ctrl, pkg/grdchk:
47      add cost penalty terms for initial uvel, vvel, eta controls
48      and I/O for prior error files
49    o pkg/mdsio:
50       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
51       (new argument) to check for tiled file in mdsioLocalDir : this fix the
52       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
53    o pkg/ctrl:
54     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
55       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
56       unused and superfluous variables
57     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
58    o pkg/ecco
59     - enable adjoint of Stevens OB
60    o pkg/ctrl/ecco/grdchk:
61      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
62        Fortunately, we do not have any tests for the numerous cpp-flagged
63        option of "obcs as control parameters" so we will never know
64        if this is an improvement (but at least now things compile).
65      - remove an obsolete initialization from ecco_cost_init_barfiles.F
66      - fix some problems within never used ifdefs to make the code compile
67    o pkg/obcs:
68     - Refine Interior mask definition to work with more complex OB (e.g.
69       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
70       read in Interior mask from file. Check if Interior mask is consistent
71       with OB list of indices.
72    o pkg/seaice
73     - beginning code for a seaice tracer package,
74       but currently only used for seaice age: SEAICE_AGE
75       SEAICE_num = 4
76       iTracer = 1: area-weighted ice age
77               = 2: volume-weighted ice age
78               = 3, 4: template for one-year vs. multi-year ice
79       data.seaice has new namelist SEAICE_PARM03 for arrays related to
80       SEAICE_num
81    
82    checkpoint62t (2011/03/05)
83    o pkg/obcs:
84     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
85       then normal component. This ensures that the normal component is set
86       correctly even when it conficts with tangential setting from an other OB.
87       Affects results of test-experiment seaice_obcs: update the output.txt
88    o pkg/obcs:
89     - add code to monitor statistics of dynamical fields at OB.
90     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
91       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
92       - change default: balance the Net inflow through all OB (instead of balancing
93         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
94     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
95       to match Nortern OB inflow (OBCS_balanceFacN=0).
96    o pkg/seaice:
97     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
98    o pkg/seaice (seaice_growth v 1.113):
99     - reverting seaice_growth to v 1.111 in order to have code with exact bit
100       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
101       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
102       runtime flag SEAICEareaFormula is kept but is inactive
103    o model/src:
104     - add new param to scale curvilinear grid distance and area when using
105       a different sphere radius from the grid-files.
106     - test/check multi-threads EXCH applied to local variable (cg2d_x)
107    o adjoint:
108     - enable adjoint of Stevens OB
109     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
110       (a bit delicate because of potentially modified adj. common block structure;
111       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
112    
113    checkpoint62s (2011/02/15)
114    o pkg/seaice (seaice_growth v 1.112):
115     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
116       computing the ice cover tendency from effective thickness tendencies. Include
117       Ian Fenty's formula.
118     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
119       SEAICEareaFormula.
120     - simplify notations for the various d_HEFF/d_AREA terms.
121    o pkg/gmredi:
122     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
123       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
124       add a verification test-run (front_relax.bvp) to test GM_useBVP.
125    o pkg/seaice (seaice_growth v 1.111):
126     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
127     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
128       also melt ice.
129    o pkg/seaice:
130     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
131     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
132    o pkg/cheapaml:
133     - from Nico Wienders: New version of this package.
134    o pkg/flt:
135     - add CPP options to prevent floats to re-enter the opposite side of
136       a periodic domain (default: keep periodicity)
137    o pkg/gmredi:
138     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
139       (needed for multi-dim advection).
140     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
141    o model/src:
142     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
143    o tutorial_tracer_adjsens
144     - extend to NLFS and replace maskC by hFacC
145       (change reference output accordingly)
146    
147    checkpoint62r (2011/01/24)
148    o testreport:
149     - add option -deloutp (-do) to remove output file after successful run
150     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
151       extract exact list of procs from this file ; adjust COMMAND by
152       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
153    o pkg/ecco: replace old ineffective way of penalizing deviations from
154      first guess (of obcs) with code by Matt Mazloff
155    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
156      exf/cal
157      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
158        and handle case of obcs?period == 0
159        Not affected by these changes: There is still an inconsistency in
160        the computation of start/endrec for the obcs variables for ALLOW_CAL
161        defined (see comment by Menemenlis, 7-Mar-2003)
162      - make S/R ctrl_get_gen_rec return something meaningful even if
163        ALLOW_CAL is not defined
164      - ctrl_getobcs?: simplify code so that it does not need to use
165                       S/R exf_swapfields
166    o testreport:
167       allow to test MPI with different number of processors for each experiment:
168       create file "SIZE.h.mpi" in each build dir.
169       Note: update of "-command" argument not yet implemented.
170    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
171      alleviate the need for additional 3D tapes when using
172      the non-inear free surface in the adjoint. This is done
173      by adding an 'update' of hfacc etc. to their current
174      value at the beginning of forward_step.F.
175    o pkg/seaice
176      seaice_lsr: move stress-divergence computations out of outer pseudo-
177      timestepping loop
178    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
179      up, so that the calls of the ctrl_* subroutines are really at the end
180      of the routine.
181    o pkg/gmredi:
182      allow to specify a 2-D horizontal map and a 1-D vertical profil
183      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
184    o pkg/seaice:
185      move lsr iterations from seaice_dynsolver to seaice_lsr.
186    o pkg/seaice:
187      reduce memory footprint of seaice mutldim advection tapes,
188      by using a 2D tape independent of the generic_advdiff ones,
189      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
190    
191    checkpoint62q (2010/12/29)
192    o model/src:
193      - check horizontal grid-spacing for unset or zero/negative values.
194      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
195    o pkg/flt:
196      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
197      - precision of input and output files set according to readBinaryPrec
198        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
199      - initial float position from tiled file was not converted to index space
200        (looks like a bug): fixed to make it similar to initial pos. global file.
201    o global_ocean.cs32x15:
202       change SIZE.h of AD set-up to get same tiling as with MPI.
203       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
204    o model/src:
205       add flag to control printing of domain fields (bathymetry, hFac ...) in
206       ini_mask_etc (call to plot_fieds_xy*).
207    o pkg/thsice:
208       if useEXF, some forcing fields are not valid in overlap: fixed by computing
209       over the interior only + apply EXCH at the end (like with SEAICE advection).
210    o pkg/mdsio:
211      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
212        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
213      - change barrier call for safe multi-threads access to 3-D shared buffer.
214      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
215      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
216        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
217    o pkg/flt:
218      - add fourth-order Runge-Kutta integration
219      - add basic exch2 support (only 1 facet supported so far!)
220    o pkg/mdsio+rw:
221      new S/R to read local (or tile independent) vector (read counterpart of
222       mds_writevec_loc, and front-end write_glvec_rl/rs).
223    o global_ocean.cs32x15: additional input_ad.seaice experiment
224        that uses pkg/seaice rather than pkg/thsice.
225        (using multidim advection for seaice)
226    o towards more F95 syntax for array specification in namelist:
227      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
228        of all verification experiments.
229           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
230          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
231      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
232    o global_ocean.cs32x15: additional input.seaice experiment
233        that uses pkg/seaice rather than pkg/thsice.
234    
235    checkpoint62p (2010/12/17)
236    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
237        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
238    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
239        allow for use of multim. advection in seaice adjoint.
240    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
241      - first attempt to close budgets by taking into account the freshwater
242        flux implied by the sublimation of snow and ice. So far only the
243        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
244        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
245    o eesupp/src:
246      new S/R with new option (NML_EXTENDED_F77) to change array specification
247      from F95 standard to commonly accepted extended F77 form.
248      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
249      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
250      for less tolerant f77 compiler (e.g., pgf77, g77).
251    o globalFiles:
252      commented out in parameter file "data" since it's not safe with MPI
253      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
254      in this case); no longer commented out in restart test (tst_2+2).
255    o add adTapeDir to specify a special directory where adjoint tapes are
256      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
257      and cannot be used together with mdsioLocalDir.
258    o nesting pkgs:
259      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
260      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
261      - add parameter files + utils dir + output from short run on beagle.
262    o pkg/seaice:
263        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
264    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
265      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
266    
267    checkpoint62o (2010/11/25)
268    o pkg/exf:
269      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
270    o pkg/seaice:
271      - seaice_ocean_stress: split a loop for better vectorization of the
272        adjoint code
273      - seaice_growth.F: fix bug in conservation of freshwater connected to
274        capping of heff, put contribution into d_HEFFbyNEG
275      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
276        by something more sensible (parameters that are what their name implies)
277      - change some defaults, so that by default exf-parameters are used for
278        things like rhoAir, cpAir,latent/sensible heat parameters, in order
279        to reproduce the old results, many data.seaice now contain funny values
280        for cpAir and latent heat of sublimation
281    o packages_readparms.F: move exf_readparms up in line so that
282        exf-parameters are visible for other packages (e.g. seaice)
283    o debugMode & debugLevel=2:
284      - differentiate between debugMode & debugLevel=2:
285        debugMode: controls printing of debug messages (sequence of S/R calls).
286        debugLevel: controls printing of algorithm intermediate results and stats.
287      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
288        => allows to print debug-stats without all sequence of call messages.
289      - switch control of debug print from debugLevel to debugMode in many S/R.
290    o pkg/obcs (obcs-sponge):
291        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
292        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
293    o pkg/generic_advdiff:
294      - record overlap minimum size for each advection scheme;
295      - refine criteria on overlap minimum size;
296      - check and stop (in gad_check) if overlap size is too small.
297    o pkg/obcs:
298      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
299        once, in ptracers_implicit.F)
300      - with seaice: remove test on empty file name in obcs_apply_seaice (always
301        apply OB values when tile has OB)
302    o model/src, coriolis setting:
303      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
304        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
305        files (selectCoriMap=3) with any grid.
306      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
307    o pkg/seaice/seaice_growth.F:
308        a few cosmetic changes that reduce the number of lines of code
309    o pkg/obcs: add boundary conditions following Stevens (1990)
310      - the code follows old MOM/NAOSIM code
311      - so far it is only implemented for the eastern and western boundaries
312        and NOT for pTracers
313    o pkg/rbcs:
314      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
315        beginning of the first rbcs forcing period.
316      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
317        offline package, i.e., one file per time, labeled by iteration number;
318        deltaTrbcs sets the timestep with which the data was generated;
319        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
320      - rbcsForcingCycle=0 makes forcing non-cyclic.
321      - make arithmetic safe for negative times and odd forcing periods.
322    
323    checkpoint62n (2010/11/09)
324    o pkg/seaice:
325        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
326    o pkg/obcs:
327       New S/R to copy tracer value from the OB location to narrow band region
328        (width = same as overlap) beyond the OB: preserve OB value (needed for
329        high-order scheme) which were overwritten by EXCH call if in overlap
330        region. Applied to theta, salt, ptracer and advected seaice variables.
331       With seaice: use maskInC in similar way as in gad_advection.F,
332        in seaice_advection.F and advect.F.
333       Update output of experiment seaice_obcs and change exp4 to test OBCS with
334        4th order Adv.Scheme. for pasive salt and ptracer.
335    o tools/genmake2:
336      - when looking for an optfile (not specified), only search for Fortran compiler
337        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
338      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
339        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
340      - set default for CPP to "cpp -traditional -P" (was the case without specifying
341        an optfile, but otherwise default was just "cpp".
342      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
343      - when "CC" is not set in the optfile, look for possible C compiler
344        (instead of just setting CC=cc)
345      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
346        => add a ".F" to ".o" rule for source files with no "#include" (such as
347           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
348      - move gfortran before g77 in list of possible Fortran compiler (consistent
349        with reference compiler switch from g77 to gfortran)
350    o pkg/seaice:
351      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
352        seaice_check that stops the model, when the CPP flag is used.
353      o seaice_growth.F: make capping of ice volume conserving by returning the
354        capped ice as freshwater to EmPmR. This does not change the verification
355        experiments but will change runs where the capping is acutally active
356    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
357      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
358         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
359         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
360    o tools/genmake2:
361      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
362      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
363      - clean previous genmake log files before anything else.
364      - change Makefile to remove testreport log files (*.tr_log) and genmake log
365        files only with "CLEAN" target (instead of "Clean");
366    o pkg/generic_advdiff:
367      Change OBCS in multiDim advection (gad_advection.F):
368       Use maskInC to prevent intermediate update of tracer-field in OB regions,
369       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
370       which were applying future time-step OB values.
371      This way, all explicit calculations use current-time-step OB values
372       (simpler and more consistent).
373      Affects results when set-up uses time-varying OBC and multi-dim advection;
374       update output of experiment seaice_obcs.
375    o pkg/seaice:
376      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
377       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
378         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
379      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
380       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
381       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
382    o pkg aim (2010/10/26):
383      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
384        formulation with obliquity, eccentricity, ... as run-time parameters,
385      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
386        upward shortwave radition at the surface (all-sky and clear-sky).
387    o pkg/obcs:
388      - writing sections with globalFiles=T does not work: switch to tiled-files
389        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
390      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
391      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
392    
393    checkpoint62m (2010/10/21)
394    o pkg/seaice: vectorize seaice_solve4temp.F
395      - move iterations loops outside of i/j-loops
396      - requires 2D arrays for TB and effConduct
397      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
398        modified in this routine
399      - a little bit of clean up, adjusting indentation, etc.
400      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
401        performance and '**TWO' by '**2' (because TWO is a float),
402        replaced ONE, ZERO
403    o eesupp/src:
404       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
405    o pkg/seaice/seaice_growth.F
406      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
407      merging process. The merged routine has two branches, and one activates the 'evolution'
408      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
409      In summary, here is what the '10/10 revision' did consist of
410        part 1: seaice_growth.F revisions 1.71 to 1.75
411          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
412            The emphasis here was on improving readability (e.g. by trying to use meaningful
413            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
414        part 1.5:
415          - revising the lab_sea experiment to make it a more useful (i.e. stable
416            and representative of an actual model run). This was done by generating a
417            (winter) pickup to start from, switching back the main experiment dynamic
418            solver from evp to lsr, having one of the experiments use the free drift solution.
419        part 2: seaice_growth.F revisions 1.76 to 1.85
420          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
421          - Sorting out the various fields units and sign (set early on and reset at the end)
422            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
423            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
424          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
425            and simplifying logical expressions to further improve readibility.
426        part 3: seaice_growth.F revisions 1.86 to 1.89
427          - Re-organize the blocks of code more logically.
428          - Merging the '_if.F' pieces that add something new.
429    o pkg/thsice:
430      - vectorize thsice_solve4temp and thsice_get_exf.
431        Problem: thsice_solve4temp has an unvectorizable statement that
432        might also be problematic for TAF
433      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
434        does not change the verifcation experiment, but will change all
435        experiments that have this flag undefined (not tested in verification);
436        a little reorganization to save a few 2D fields and recomputations
437      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
438      - 2nd step:  fix some store dirs
439        o seems to work somewhat, i.e. using ifort but not g77
440        o likely cause are incomplete init. or recomputation
441        o start verification/global_ocean.cs32x15/input_ad.thsice
442    o pkg/obcs: add support for exch2
443      - the position of the boundary and prescribed values are specified using
444        a global domain with exch2 facets stacked
445        - in x for N,S boundaries (like W2_mapIO=-1)
446        - in y for E,W boundaries (so E,W boundaries do not overlap)
447    o pkg/mdsio: add support for writing global sections with exch2
448        file layout is as for obcs described above:
449        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
450        - for y-z sections, facets are stacked in y
451    o pkg/thsice:
452       - change a few routines for better vectorization: thsice_albedo.F,
453         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
454         not affected, but in particular the latter routine has changed
455         dramatically (not necessarily easier to read now).
456       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
457       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
458    o verification/lab_sea:
459      - overhaul of the forward model experiments. The main motivation
460        for this revision is that lab_sea has proven quite fragile (when
461        changing the sea-ice code, and switching platforms) to a point
462        when failures were very hard to attribute to specific code problems.
463      - the suspected reason for this fragility is noise amplification by evp so,
464        to start with, we decided to replace evp with lsr in the main experiment.
465      - the input.lsr experiment thus became obsolete and was removed.
466      - it was replaced with the input.fd experiment that uses an
467        analytical "free drift" solution as the ice velocity field.
468      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
469        will hopefully allow us to discriminate problems due to dynamic solvers
470        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
471        us to test additional options, along with the salt plume package.
472      - Finally a pickup was generated (at the end of a one year run) to
473        make the tests more representative of an actual model run. Previously
474        the tests starting point was a 1m thickness of ice everywhere.
475    o pkg/seaice:
476      - introducing S\R seaice_freedrift.F that compute the
477        analytical solution to an approximate ice momentum
478        equation (i.e. the simple stress/coriolis balance).
479      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
480        of the free drift velocity field, and enable its use.
481        To actually use the free drift solution as the model ice
482        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
483    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
484    
485    checkpoint62l (2010/10/04)
486    o pkg/seaice:
487      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
488      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
489       version (with USE_ORIGINAL_SBI undef);
490    o add hooks for new packages OASIS, the package will follow
491      (hooks exclude the seaice pkg for now)
492    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
493      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
494      rather than mdsio_readvector.F/mdsio_writevector.F, within
495      adread_adwrite.F to read/write adjoint-related tapes to disk.
496    o eesupp and pkg/mdsio: ALLOW_WHIO
497      Option to write/read 2D fields to files including tiles halos.
498      The main purpose is for adjoint related "tape I/O".
499      The secondary purpose is for debugging phases.
500      A word on those rather specifically intended purposes.
501      The code was meant to be stripped down to the bare minimum.
502      Typically, there is a unique and basic mapping to the global
503      buffer (tile by tile, then proc by proc, then level by level), and
504      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
505      meant to generate user friendly outputs of various shapes and forms.
506      Rather it is intended, for the knowledgeabale developers,
507      to be largely independent of the many mdsio options, to allow
508      outputs of tiles+halos in debugging phases and in adjoint runs,
509      and to allow some flexibility in tuning (adoint) I/O depending on each
510      file system behavior. With regard to tuning, most of the potential knobs
511      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
512      to specify directories, to specify the typical size of I/O calls, etc.)
513      are not yet included, and will be added if they prove useful.
514    o pkg/seaice:
515       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
516    o pkg/seaice:
517       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
518       code (seaice_budget_ice_if.F) which enable to recover old standard
519       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
520       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
521    o model/src (rStar):
522       use simple average (not area weighted) of rStarFac at U,V point when using
523       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
524       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
525    
526    checkpoint62k (2010/09/17)
527    o adjoint
528       * changed verification/global_ocean.cs32x15 ; adjoint now tests
529         Adams-Bashforth 3 + NLFS + RSTAR
530       * some more modifs required for ECCO-GODAE v4
531    o pkg/seaice
532       add SEAICE_AGE_VOL option to use volume instead of area for
533       integrating SEAICE_AGE
534    o model/src:
535       first check-in of sigma & hybrid-sigma coordinate code ; also includes
536       non-linear free-surface parts ; but pressure-gradient not yet coded.
537    o pkg/ptracers:
538       option for ptracer to convert Salt Relax into additional EmP.
539        tested in exp. global_ocean.90x40x15.dwnslp (update output)
540    
541    checkpoint62j (2010/08/25)
542    o pkg/ggl90:
543       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
544    o pkg/dic: car_flux.F, phos_flux.F
545      - reduce number of exp-calls in order to improve performance
546      - clean up a little (replace fields by their macros, etc., fix
547        typo in CPP-flag)
548    o pkg/ggl90: minor changes
549      - GGL90diffKrS was removed --> always use GGL90diffKr
550      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
551      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
552        (commented out for now)
553      - change in max/min operations to ensure that smoothing is ok
554      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
555      - always use diffKrNrT as background profile (i.e. never use diffKr field)
556    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
557    o pkg/dic:
558      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
559        vectorization
560      - small bug fix in insol for the unlikely case of a cartesian grid
561      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
562        + now vectorize, which also removes adjoint recomputations;
563        + replace integer maksp1 by _RL maskp1
564        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
565    
566    checkpoint62i (2010/07/21)
567    o pkg/flt:
568      - with OBCS: stop floats which enter the OB region
569    o model/src:
570      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
571        for implicit vertical advection.
572    o pkg/seaice:
573     - account for melting in seaice age evolution.
574     - remove double counting of seaice ridging effect on seaice age.
575    
576    checkpoint62h (2010/06/18)
577    o pkg/exch2:
578     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
579    o tools/genmake2
580      - remove "-pdefault" option: redundant with the use of "packages.conf";
581      - remove file pkg/pkg_default : set the default as a pkg group
582        ("default_pkg_list") defined in pkg/pkg_groups;
583      - fix for case pkg/pkg_depend is missing (was hanging before);
584      - add option "-pgroups" to specify a different pkg_groups than the default.
585    o verification/adjustment.cs-32x32x1:
586       add a "minimal" set-up test (code_min & input_min) which only compiles
587       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
588    o tools/genmake2
589      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
590      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
591    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
592      files are nearly the same anyway.
593      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
594       - redefinition of tau(i,i) (by a factor of ustar)
595       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
596       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
597       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
598       - replace
599         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
600         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
601         by
602         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
603         (changes results)
604       -> exf_bulkformulae v1.22,
605          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
606          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
607                    output.txt 1.63
608           offline_exf_seaice: output.seaicetd.txt 1.7
609           seaice_obcs: output.txt 1.10)
610      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
611       -> exf_bulkformulae v1.23,
612          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
613          and global_ocean.cs32x15.icedyn (only 11 matching digits)
614      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
615    o adjoint of exch-1:
616     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
617       (note: was already like this when using EXCH-2) and remove flow dir
618       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
619     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
620     - update pkg/exch2 diff list.
621    
622    checkpoint62g (2010/05/19)
623    o eesupp/src (exch-1):
624     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
625       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
626       (renamed to exch1_*rx_cube.F).
627     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
628       to call new exch1 S/R ; update Makefile and .cvsignore.
629     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
630       exch2_xy_rx later)
631      Note: after updating your code, need to run "make clean" in eesupp/src
632    o test experiment bottom_ctrl_5x5:
633       new output_adm.txt with fewer grdchk & less monitor output.
634    o model/src:
635      remove the call to ini_cori in initialise_varia.F (just keep the usual one
636       in initialise_fixed.F). More consistent with coriolis & horizontal grid
637       beeing treated in the same way (ini_grid is not called a 2nd time).
638    o pkg/exf:
639    - rewrite exf_bulk_largeyeager04.F for better vectorization, changes    - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
640    global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated    global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
