4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8     - Added SEAICEuseTILT run time switch : if set to
9     false then omit the tilt term in seaice dynamics.
10     - Fix free drift calculation.
11    o pkg/shelfice:
12      When initializing SHELFICEDragQuadratic, set default to be
13      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
14      but retain option to set it independently
15      (inconsistenty spotted by Veronique Dansereau)
16    o eesupp/inc:
17      - in EEPARAMS.h, add real-type constant for some frequently used simple number
18         (0,1,2,1/2), with name explicitly referring to RS/RL type.
19    o model/src:
20      - move balancing of relaxation terms to new S/R balance_relax.F.
21    o pkg/autodiff:
22      re-write active I/O high-level (control) S/R:
23      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
24      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
25      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
26        MDS_READ/WRITE_FIELD); change loops to multi-threads.
27      - update and merge active_file_control_slice.flow into active_file_control.flow
28      - update the calls in lower level S/R (active_file.F, active_file_g.F and
29        active_file_ad.F) keeping the argument list and function unchanged.
30      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
31        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
32      - new low-level active I/O routines, one for each type (RL/RS), for active var
33        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
34        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
35        right type.
36    o autodiff and RS=real*4:
37      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
38        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
39      - change argument type of 3-D mask argument to _RS to match type in the call
40        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
41    o pkg/thsice:
42      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
43      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
44        fresh-water flux: uniform correction or proportional to local precip.
45    o pkg/ctrl:
46      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
47      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
48                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
49      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
50    
51    checkpoint63q (2012/07/30)
52    o pkg/autodiff:
53      note about monitor and snap-shot of ad-variables:
54      a) need to apply ADEXCH before monitor or output of ad-vars to include
55       overlap contributions (was done for adjDump but missing for monitor).
56      b) since ADEXCH implies adding overlap values to interior array, machine
57       truncation error is expected when adding an ADEXCH call in the middle of
58       the time-stepping (although mathematically identical).
59      modifs:
60      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
61        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
62      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
63        apply ADEXCH before monitor or snap-shot of ad-variables:
64           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
65      - implement new method (copy+adexch) for snap-shot and monitor of main model
66        ad-vars (initially not used by default -> output unchanged).
67      - change default (set to 2) to use new method and update few output_adm.txt
68        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
69        and both tutorial_tracer_adjsens tests).
70      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
71        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
72    o pkg/ctrl:
73      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
74      generic control variables via
75      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
76      Only required customization should be S/R ctrl_map_ini_genarr.F
77      (routine in repository contains example)
78    o pkg/exf:
79      - fix and refine checking of surface-relaxation setting when using EXF
80    o verification (adjoint exp):
81      - reduce length of simulation by half for experiment global_ocean.cs32x15
82        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
83    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
84      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
85        of KE that can occur with aggressive optimization
86      + put quadratic bottom drag calculation in separated loops (only done if
87        using bottomDragQuadratic)
88    o model/src: CG2D_NSA
89      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
90         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
91      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
92         change cg2d residual target to be expressed in Wunits (=> do not normalise
93         RHS ; this fix global_max Pb with TAF); update output.
94    o verification/tutorial_tracer_adjsens:
95       improve parameter consistency (and get rid of warnings):
96       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
97       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
98       - use staggerTimeStep (for stability) in som81; use default rotation period.
99    o pkg/exch2:
100      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
101        reset to 0 = 1 long line in X)
102    o pkg/mdsio:
103      - fix reading of dimensions from meta file for large-size domain
104    o model/src:
105      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
106      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
107        Cubed-Sphere Exch with CS-corners inside the domain;
108        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
109        globalArea and to set hasWetCSCorners.
110      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
111        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
112      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
113        useCDscheme and useCubedSphereExchange).
114    o pkg/seaice/seaice_growth.F :
115      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
116        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
117        when the previous code was not correct.
118      - in all cases diagnoze the boundary condition mismatch to SIaaflux
119      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
120        that term to QNET (essentially to set the melt/freeze water to 0degC).
121        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
122    o verification/global_ocean.cs32x15/input.seaice :
123      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
124      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
125      - update results (output.seaice.txt) accordingly.
126    o verification/lab_sea/input/data.seaice :
127      - remove SEAICEheatConsFix, which is now be tested
128        in global_ocean.cs32x15. The presently coded fix
129        is only consistent with real fresh water + nlfs.
130      - update results (output.txt) accordingly.
131    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
132    o AD_CONFIG.h file:
133      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
134      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
135        add it explicitly in each fortran src file where it is needed.
136        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
137        thus introducing potentially wrong dependency; therefore, better to include
138        it only where it's really needed, and after any other included OPTIONS file
139        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
140        or ALLOW_TANGENTLINEAR_RUN).
141    
142    checkpoint63p (2012/07/06)
143    o pkg/autodiff:
144      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
145      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
146        which are now read from new parameter file "data.autodiff" (inAdExact
147        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
148      - add file "data.autodiff" in all verification/*/input_ad/ directories.
149      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
150        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
151    o verification/tutorial_tracer_adjsens/
152      - add extra sub-verification which uses "SOM" advection scheme
153        (2nd Order-Moment Advection Scheme, Prather Limiter) with
154          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
155        and in data:
156          multiDimAdvection=.TRUE.,
157          tempAdvScheme=81,
158          saltAdvScheme=81,
159    o model/src:
160      - introduce ALLOW_BALANCE_RELAX which allow the removal
161       of the global mean of relaxation terms by setting
162       balanceThetaClimRelax and balanceSaltClimRelax
163      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
164       This case is now treated appropriately in seaice_growth.F
165    o pkg/seaice:
166      - do balanceEmPmR and balanceQnet based on the net fluxes
167        (SItflux) that enter the ocean+ice system rather than QNET
168        and EMPMR. Works best in real fresh water.
169      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
170        out of the diagnotics bloc, and stored in global arrays.
171    
172    checkpoint63o (2012/06/29)
173    o vertical mixing schemes:
174      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
175      - replace computation of density (in Function STATE1, opps_calc.F) by a call
176        to S/R FIND_RHO_SCALAR
177      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
178        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
179        affects output (vermix.ggl90) at truncation level.
180    o testreport:
181      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
182        (nSx,nSy) for the number of threads (from eedata.mth)
183    o model/src:
184      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
185        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
186    o verification/tutorial_tracer_adjsens/
187      - compile with ALLOW_CG2D_NSA
188      - run with nonlinFreeSurf=3
189      - update reference output_adm.txt
190    o tools/genmake2:
191      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
192        refine usePROFILES switching off (only when NetCDF is not available).
193    o verification (atmospheric set-up):
194      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
195    o pkg/profiles : refine profiles and files handling.
196    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
197    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
198      - changes to use model/src/the_main_loop.F rather than the ecco version
199        in ecco type adjoint runs.
200    o model/src:
201      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
202      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
203      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
204    o model/src:
205      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
206        update output of test experiment bottom_ctrl_5x5.
207    o pkg/generic_advdiff:
208      - implement vertical bi-harmonic diffusion (for now, only for T & S and
209        only explicitly).
210    o verification/bottom_ctrl_5x5/
211      update reference output (results changed quite some time ago,
212      not sure when; but new reference results look ok in terms of grdchk)
213    o verification/1D_ocean_ice_column/
214      For verification purposes, the exact adjoint rather than an approx.
215      should be used (e.g., to comare against F.D. or TLM).
216      removed autodiff_inadmode*_ad.F routines in code_ad/
217      Update results/ accordingly.
218    o pkg/cal:
219      - change cal_getdate.F so that output date is function of input time only
220        (less ambiguous, not mixed up with input iteration number).
221      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
222    o pkg/diagnostics:
223      - implement calendarDumps also for stats-diags
224      - implement calendarDumps also for snap-shot output (negative freq)
225      - for now, ignores calendarDumps if non-zero phase-lag.
226    
227    checkpoint63n (2012/06/04)
228    o model/src:
229      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
230        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
231      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
232        similar to calc_r_star.F); update results of experiment internal_wave and
233        tutorial_global_oce_in_p (affected @ truncation level).
234    o pkg/shelfice:
235      - add parameterisation of advective-diffusive flux into the ice shelf
236        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
237      - simply eps3/3a computation
238    o eesupp:
239     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
240       between tiles, just fill-in edges assuming locally periodic subdomain) and
241       add corresponding exchange subroutines (EXCH0);
242     - new CG-solver version (_EX0) for disconnected-tiles special case.
243    o model/src (CG-solvers):
244     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
245       (similar final residual output and max-Iter number as with standard version);
246     - allows to store and use lowest-residual solution (standard & _SR versions);
247     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
248     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
249    o eesup/src:
250     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
251       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
252    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
253    
254    checkpoint63m (2012/04/27)
255    o pkg/shelfice:
256     - account for partical cells in surface level below ice-shelf for hydrostatic
257       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
258    o ad test experiments:
259     - update and rename to "ad_optfile.local" local AD-optfile specific to a
260       particular adjoint verification experiment (in verification/*/code_ad/)
261    o pkg/seaice & pkg/exf:
262     - Part two of ECCO-CLIVAR code merges.
263       Completes merge of seaice area relax. code.
264       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
265       to be set in EXF_OPTIONS.h since this pkg controls its I/O
266       (and avoids second CPP option in SEAICE_OPTIONS.h)
267     - change default value of costIceStart & costIceEnd to a valid date.
268     - add snowPrecip to HSNOW in seaice_growth
269    o pkg/ptracers:
270     - move ptracers summary and setup check into separated S/R ; add a check for
271       valid PTRACERS_Iter0 value (error+stop or just warning).
272    o pkg/cal (+ pkg/ecco):
273     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
274       as input; and for AD, unless both are not differentiable (e.g., k index)).
275    o model/src:
276     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
277       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
278       temporary set to usingZCoords value (to be changed to F when using shelfice).
279     - hydrostatic pressure: implement partial cell near the surface also for
280       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
281       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
282    o pkg/ctrl/ctrl_init.F:
283     - add a formal parameter to s/r ctrl_init_rec to print
284       xx_$(ctrl_valiable)_file for easier debugging
285     - move call of cal_* routines into the if-block where they are really
286       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
287       to specify a startdate
288    o pkg/seaice:
289     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
290       global_ocean.cs32x15/code versions).
291     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
292       verification experiment global_ocean.cs32x15.seaice and update results.
293    o pkg/exf:
294     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
295       (according to useExfYearlyFields).
296    o pkg/cal:
297     - move calendar setting & summary (previously in cal_readparams.F) into new
298       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
299       length of the simulation is set (after SET_PARMS call); This is an attempt
300       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
301     - For safety: keep a record of pkg/cal parameter settings status
302               to allow to STOP if one pkg/cal S/R is called too early.
303     - add a stop in all basic pkg/cal subroutines if called before setting is done.
304     - modify cal_getdate.F: stop when nothing was returned;
305       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
306       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
307    
308    checkpoint63l (2012/04/04)
309    o pkg/bbl:
310      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
311        update global_with_exf output.yearly.txt file.
312    o pkg/cal:
313      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
314      - remove 2 unsused and very short (1 line only) functions ;
315      - remove unsused subroutines from AD-Diff list.
316    o model/src:
317      - start to implement clean wait to stop in initialization S/R (config_check.F,
318         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
319    o folowing PRINT_MESSAGE changes:
320      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
321    o pkg/bbl:
322      - modification so it can work with z*
323      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
324      - global_with_exf/input.yearly verification; changes output.yearly.txt
325    o eesupp/src:
326      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
327        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
328      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
329        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
330      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
331      - when using MPI, always set usingMPI=T ; set default accordingly and stop
332        if not consistent.
333      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
334        argument is zero (in case called within single-thread section).
335    o pkg/fizhi:
336        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
337        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
338    o pkg/exch2:
339      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
340        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
341      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
342        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
343        with bad ones coming from a not-yet-updated halo.
344        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
345    o pkg/frazil:
346        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
347        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
348    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
349    o verification/lab_sea
350      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
351      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
352      * nTimeSteps 3 -> 4
353      * changed reference output accordingly
354    o pkg/ctrl:
355      * fix ctrl_get_gen for xx_sst, xx_sss
356    o pkg/fizhi:
357      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
358        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
359      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
360        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
361        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
362    o pkg/gmredi:
363      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
364    o pkg/fizhi:
365      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
366        (old)aces open64 tuv test.
367    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
368    o pkg/mom_vecinv:
369      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
370        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
371        with non-lin free-surf).
372    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
373      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
374      some compilers (gfortran 4.6.0 on MacOS)
375  o momentum:  o momentum:
376    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM    - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
377      & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised      & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
