5      ==============================      ==============================
6    
7  o pkg/seaice :  o model/src:
8      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
9        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
10    o verification/tutorial_tracer_adjsens/
11      - compile with ALLOW_CG2D_NSA
12      - run with nonlinFreeSurf=3
13      - update reference output_adm.txt
14    o tools/genmake2:
15      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
16        refine usePROFILES switching off (only when NetCDF is not available).
17    o verification (atmospheric set-up):
18      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
19    o pkg/profiles : refine profiles and files handling.
20    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
21    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
22      - changes to use model/src/the_main_loop.F rather than the ecco version
23        in ecco type adjoint runs.
24    o model/src:
25      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
26      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
27      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
28    o model/src:
29      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
30        update output of test experiment bottom_ctrl_5x5.
31    o pkg/generic_advdiff:
32      - implement vertical bi-harmonic diffusion (for now, only for T & S and
33        only explicitly).
34    o verification/bottom_ctrl_5x5/
35      update reference output (results changed quite some time ago,
36      not sure when; but new reference results look ok in terms of grdchk)
37    o verification/1D_ocean_ice_column/
38      For verification purposes, the exact adjoint rather than an approx.
39      should be used (e.g., to comare against F.D. or TLM).
40      removed autodiff_inadmode*_ad.F routines in code_ad/
41      Update results/ accordingly.
42    o pkg/cal:
43      - change cal_getdate.F so that output date is function of input time only
44        (less ambiguous, not mixed up with input iteration number).
45      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
46    o pkg/diagnostics:
47      - implement calendarDumps also for stats-diags
48      - implement calendarDumps also for snap-shot output (negative freq)
49      - for now, ignores calendarDumps if non-zero phase-lag.
50    
51    checkpoint63n (2012/06/04)
52    o model/src:
53      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
54        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
55      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
56        similar to calc_r_star.F); update results of experiment internal_wave and
57        tutorial_global_oce_in_p (affected @ truncation level).
58    o pkg/shelfice:
59      - add parameterisation of advective-diffusive flux into the ice shelf
60        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
61      - simply eps3/3a computation
62    o eesupp:
63     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
64       between tiles, just fill-in edges assuming locally periodic subdomain) and
65       add corresponding exchange subroutines (EXCH0);
66     - new CG-solver version (_EX0) for disconnected-tiles special case.
67    o model/src (CG-solvers):
68     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
69       (similar final residual output and max-Iter number as with standard version);
70     - allows to store and use lowest-residual solution (standard & _SR versions);
71     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
72     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
73    o eesup/src:
74     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
75       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
76    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
77    
78    checkpoint63m (2012/04/27)
79    o pkg/shelfice:
80     - account for partical cells in surface level below ice-shelf for hydrostatic
81       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
82    o ad test experiments:
83     - update and rename to "ad_optfile.local" local AD-optfile specific to a
84       particular adjoint verification experiment (in verification/*/code_ad/)
85    o pkg/seaice & pkg/exf:
86     - Part two of ECCO-CLIVAR code merges.
87       Completes merge of seaice area relax. code.
88       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
89       to be set in EXF_OPTIONS.h since this pkg controls its I/O
90       (and avoids second CPP option in SEAICE_OPTIONS.h)
91     - change default value of costIceStart & costIceEnd to a valid date.
92     - add snowPrecip to HSNOW in seaice_growth
93    o pkg/ptracers:
94     - move ptracers summary and setup check into separated S/R ; add a check for
95       valid PTRACERS_Iter0 value (error+stop or just warning).
96    o pkg/cal (+ pkg/ecco):
97     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
98       as input; and for AD, unless both are not differentiable (e.g., k index)).
99    o model/src:
100     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
101       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
102       temporary set to usingZCoords value (to be changed to F when using shelfice).
103     - hydrostatic pressure: implement partial cell near the surface also for
104       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
105       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
106    o pkg/ctrl/ctrl_init.F:
107     - add a formal parameter to s/r ctrl_init_rec to print
108       xx_$(ctrl_valiable)_file for easier debugging
109     - move call of cal_* routines into the if-block where they are really
110       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
111       to specify a startdate
112    o pkg/seaice:
113     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
114       global_ocean.cs32x15/code versions).
115     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
116       verification experiment global_ocean.cs32x15.seaice and update results.
117    o pkg/exf:
118     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
119       (according to useExfYearlyFields).
120    o pkg/cal:
121     - move calendar setting & summary (previously in cal_readparams.F) into new
122       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
123       length of the simulation is set (after SET_PARMS call); This is an attempt
124       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
125     - For safety: keep a record of pkg/cal parameter settings status
126               to allow to STOP if one pkg/cal S/R is called too early.
127     - add a stop in all basic pkg/cal subroutines if called before setting is done.
128     - modify cal_getdate.F: stop when nothing was returned;
129       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
130       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
131    
132    checkpoint63l (2012/04/04)
133    o pkg/bbl:
134      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
135        update global_with_exf output.yearly.txt file.
136    o pkg/cal:
137      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
138      - remove 2 unsused and very short (1 line only) functions ;
139      - remove unsused subroutines from AD-Diff list.
140    o model/src:
141      - start to implement clean wait to stop in initialization S/R (config_check.F,
142         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
143    o folowing PRINT_MESSAGE changes:
144      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
145    o pkg/bbl:
146      - modification so it can work with z*
147      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
148      - global_with_exf/input.yearly verification; changes output.yearly.txt
149    o eesupp/src:
150      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
151        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
152      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
153        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
154      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
155      - when using MPI, always set usingMPI=T ; set default accordingly and stop
156        if not consistent.
157      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
158        argument is zero (in case called within single-thread section).
159    o pkg/fizhi:
160        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
161        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
162    o pkg/exch2:
163      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
164        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
165      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
166        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
167        with bad ones coming from a not-yet-updated halo.
168        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
169    o pkg/frazil:
170        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
171        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
172    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
173    o verification/lab_sea
174      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
175      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
176      * nTimeSteps 3 -> 4
177      * changed reference output accordingly
178    o pkg/ctrl:
179      * fix ctrl_get_gen for xx_sst, xx_sss
180    o pkg/fizhi:
181      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
182        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
183      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
184        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
185        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
186    o pkg/gmredi:
187      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
188    o pkg/fizhi:
189      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
190        (old)aces open64 tuv test.
191    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
192    o pkg/mom_vecinv:
193      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
194        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
195        with non-lin free-surf).
196    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
197      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
198      some compilers (gfortran 4.6.0 on MacOS)
199    o momentum:
200      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
201        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
202        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
203    
204    checkpoint63k (2012/03/17)
205    o model/src:
206       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
207         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
208       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
209         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
210    o model/src: solve_*diagonal.F
211       - replace division with multiplication by inverse (similar to original version)
212         update output of AD exp. global_ocean.90x40x15.
213       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
214         to enable the use of the vectorized & differentiable solve_tridiagonal.F
215       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
216         vertical advection (to get solve_tridiagonal tested in AD mode).
217    o pkg/seaice: ECCO-CLIVAR merge:
218      1. seaice AREA relaxation
219         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
220         * runtime flag: SEAICE_tauAreaObsRelax
221      2. modified global mean cost imbalance code: CPP option
222          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
223    o another iteration on solve_*diagonal.F
224       Make choices independent of AUTODIFF
225       Default will be the adjoinable vectorized version.
226       Alternative choices are:
227       * non-adjoinable original version with low memory footprint:
228         #define SOLVE_DIAGONAL_LOWMEMORY
229       * still adjoinable but does not vectorize (k as inner-most loop):
230         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
231    o testreport
232     - add option to use a home made wrapper around "make"
233     - remove MITGCM_IEEE env. variable (no longer active)
234    o pkg/shelfice
235     - improve computation of friction velocity for velocity dependent
236       exchange coefficients: include velocities into SHELFICEBoundaryLayer
237       block to average velocities vertically
238     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
239    o Modify diagonal solvers, now three versions (upon request):
240      #ifndef SOLVE_DIAGONAL_AUTODIFF
241        1. default version (dating back a while ago)
242      #else /* def SOLVE_DIAGONAL_AUTODIFF */
243      # ifdef SOLVE_DIAGONAL_KINNER
244        2. adjoinable version with k-innermost loop (G. Forget)
245      # else
246        3. adjoinable vectorized version of 2.
247      # endif
248      #endif /* SOLVE_DIAGONAL_AUTODIFF */
249      All flags are currently set within routines, but could/should be moved to CPP-options.
250      Array bounds for 1. are as before, for 2.,3. cover the entire domain
251      (could be changed for 1. too).
252    o verification/lab_sea (fwd):
253      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
254        use 7 categories (except hb87), new solve4temp params (except salt_plume),
255        constant salinity (=4) or variable salinity (salt_plume) done through
256        SItracer.
257    o pkg/seaice:
258      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
259      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
260         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
261        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
262        SEAICE_freeze got retired) but already better than previously with
263        SEAICE_freeze=123456.7 deg.C;
264      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
265        (safer multi-threaded setting); always set SEAICEuseEVP;
266      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
267        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
268        stop if multiple specifications for the same coeff; make sure default
269        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
270    o pkg/obcs:
271      - allow to switch to upwind 1rst order advection scheme for the advective
272        flux computation at the open-boundary; disabled for adjoint built.
273    o pkg/ptracers:
274      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
275      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
276      - add parameter to decide when to start a tracer; use internal flag to
277        know which tracer to step-forward; switch this internal flag at the top
278        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
279        for adjoint built.
280    o pkg/seaice:
281      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
282      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
283      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
284    o pkg/ecco:
285      - fix writing of output file DiagnosCost_ClimSalt/Theta
286        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
287    o pkg/seaice:
288      - add missing initialisation of COR_ICE array in dynsolver.F
289      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
290        compiled either way, and is tested in all exps (multidim was only tested
291        in lab_sea ad before).
292      - cosmetic change to prepare for future addition of ITD. no change to results.
293        no defaults change.
294      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
295      - by lack of adequate verification experiments, I further used custom versions
296        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
297        should be correct.
298      - avoid recomputations in ad.
299    o array initialisation in adjoint mode:
300      1) pkg/mom_common/mom_calc_ke.F:
301        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
302        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
303        part this initialisation is gone, resulting in Floating Point Exception
304        (caught by open64 compiler with debug option).
305      2) model/src/convective_weights.F
306        set output convectCount over the full array range (instead of doing
307        an update): this fix a similar issue when called within recomputation (adjoint)
308        which could by-pass the initialisation (normally done in the caller S/R).
309    o pkg/seaice:
310    - final version of turbulent flux params, as agreed at MIT ice meet:    - final version of turbulent flux params, as agreed at MIT ice meet:
311         SEAICE_mcPheePiston (default is ~ 0.000875)         SEAICE_mcPheePiston (default is ~ 0.000875)

319      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
320  o pkg/shelfice/shelfice_thermodynamics.F  o pkg/shelfice/shelfice_thermodynamics.F
321    - fix exponents for velocity dependent exchange coefficients: change    - fix exponents for velocity dependent exchange coefficients: change
322      from 2/3(=0) to 0.66666666666666667      from 2/3(=0) to 0.66666666666666667
