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