5      ==============================      ==============================
6    
7    o verification (atmospheric set-up):
8      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
9    o pkg/profiles : refine profiles and files handling.
10    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
11    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
12      - changes to use model/src/the_main_loop.F rather than the ecco version
13        in ecco type adjoint runs.
14    o model/src:
15      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
16      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
17      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
18    o model/src:
19      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
20        update output of test experiment bottom_ctrl_5x5.
21    o pkg/generic_advdiff:
22      - implement vertical bi-harmonic diffusion (for now, only for T & S and
23        only explicitly).
24    o verification/bottom_ctrl_5x5/
25      update reference output (results changed quite some time ago,
26      not sure when; but new reference results look ok in terms of grdchk)
27    o verification/1D_ocean_ice_column/
28      For verification purposes, the exact adjoint rather than an approx.
29      should be used (e.g., to comare against F.D. or TLM).
30      removed autodiff_inadmode*_ad.F routines in code_ad/
31      Update results/ accordingly.
32    o pkg/cal:
33      - change cal_getdate.F so that output date is function of input time only
34        (less ambiguous, not mixed up with input iteration number).
35      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
36    o pkg/diagnostics:
37      - implement calendarDumps also for stats-diags
38      - implement calendarDumps also for snap-shot output (negative freq)
39      - for now, ignores calendarDumps if non-zero phase-lag.
40    
41    checkpoint63n (2012/06/04)
42    o model/src:
43      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
44        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
45      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
46        similar to calc_r_star.F); update results of experiment internal_wave and
47        tutorial_global_oce_in_p (affected @ truncation level).
48    o pkg/shelfice:
49      - add parameterisation of advective-diffusive flux into the ice shelf
50        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
51      - simply eps3/3a computation
52    o eesupp:
53     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
54       between tiles, just fill-in edges assuming locally periodic subdomain) and
55       add corresponding exchange subroutines (EXCH0);
56     - new CG-solver version (_EX0) for disconnected-tiles special case.
57    o model/src (CG-solvers):
58     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
59       (similar final residual output and max-Iter number as with standard version);
60     - allows to store and use lowest-residual solution (standard & _SR versions);
61     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
62     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
63    o eesup/src:
64     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
65       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
66    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
67    
68    checkpoint63m (2012/04/27)
69    o pkg/shelfice:
70     - account for partical cells in surface level below ice-shelf for hydrostatic
71       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
72    o ad test experiments:
73     - update and rename to "ad_optfile.local" local AD-optfile specific to a
74       particular adjoint verification experiment (in verification/*/code_ad/)
75    o pkg/seaice & pkg/exf:
76     - Part two of ECCO-CLIVAR code merges.
77       Completes merge of seaice area relax. code.
78       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
79       to be set in EXF_OPTIONS.h since this pkg controls its I/O
80       (and avoids second CPP option in SEAICE_OPTIONS.h)
81     - change default value of costIceStart & costIceEnd to a valid date.
82     - add snowPrecip to HSNOW in seaice_growth
83    o pkg/ptracers:
84     - move ptracers summary and setup check into separated S/R ; add a check for
85       valid PTRACERS_Iter0 value (error+stop or just warning).
86    o pkg/cal (+ pkg/ecco):
87     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
88       as input; and for AD, unless both are not differentiable (e.g., k index)).
89    o model/src:
90     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
91       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
92       temporary set to usingZCoords value (to be changed to F when using shelfice).
93     - hydrostatic pressure: implement partial cell near the surface also for
94       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
95       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
96    o pkg/ctrl/ctrl_init.F:
97     - add a formal parameter to s/r ctrl_init_rec to print
98       xx_$(ctrl_valiable)_file for easier debugging
99     - move call of cal_* routines into the if-block where they are really
100       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
101       to specify a startdate
102    o pkg/seaice:
103     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
104       global_ocean.cs32x15/code versions).
105     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
106       verification experiment global_ocean.cs32x15.seaice and update results.
107    o pkg/exf:
108     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
109       (according to useExfYearlyFields).
110    o pkg/cal:
111     - move calendar setting & summary (previously in cal_readparams.F) into new
112       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
113       length of the simulation is set (after SET_PARMS call); This is an attempt
114       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
115     - For safety: keep a record of pkg/cal parameter settings status
116               to allow to STOP if one pkg/cal S/R is called too early.
117     - add a stop in all basic pkg/cal subroutines if called before setting is done.
118     - modify cal_getdate.F: stop when nothing was returned;
119       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
120       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
121    
122    checkpoint63l (2012/04/04)
123    o pkg/bbl:
124      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
125        update global_with_exf output.yearly.txt file.
126    o pkg/cal:
127      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
128      - remove 2 unsused and very short (1 line only) functions ;
129      - remove unsused subroutines from AD-Diff list.
130    o model/src:
131      - start to implement clean wait to stop in initialization S/R (config_check.F,
132         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
133    o folowing PRINT_MESSAGE changes:
134      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
135  o pkg/bbl:  o pkg/bbl:
136    - modification so it can work with z*    - modification so it can work with z*
137    - replace deltaT with dTtracerLev(k) for asynchronous time stepping    - replace deltaT with dTtracerLev(k) for asynchronous time stepping
