4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    
8    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
9    
10    checkpoint58p_post
11    o obcs: stop if obcs is used with useCDscheme = .true.
12    o shelfice:
13     - fix a sign error so that no slip at shelfice interface works
14     - remove stop for combination non-hydrostatic code and shelfice. That does
15       not mean, that the results are correct, but at least they are numerically
16       stable
17    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
18    o added adjoint exch routined for all exch*3d* routines
19      and updated flow directives
20    
21    checkpoint58o_post
22    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
23      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
24    o change controling S/R for writing pickup file (new S/R do_write_pickup)
25      and clean-up reading/writing of pickup files.
26    o fix local version of read/write pickup (NH part) in rotating_tank/code
27    o simplify EXCH interface:
28     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
29     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
30    o added the regrid package
31    o shelfice:
32     - add a simple boundary layer scheme to reduce noise
33     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
34    
35    checkpoint58n_post
36    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
37       local variable (not in common block).
38    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
39      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
40      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
41        to work with SingleCpuIO.
42    o add "_d 0" to real constant of pkg/cfc subroutines ;
43       update exp. cfc_exemple & tutorial_cfc_offline output files.
44    o multi-threading and IO:
45      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
46        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
47      - barrier before and after reading.
48      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
49      - avoid using MDS_WRITELOCAL for LAND pkg output.
50      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
51        common-block variables ; Allows multi-threading with master-thread IO.
52    o change default MAX_NO_THREADS from 32 to 4 ;
53      and stop cleanly when MAX_NO_THREADS is too small.
54    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
55    
56    checkpoint58m_post
57    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
58       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
59    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
60       keep global_ocean.90x40x15 (for AD testing) with former secondary test
61       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
62    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
63        add MITgcm_tutorials (= code + all the tutorials)
64    o ecco, option to compute cost for total ssh (mean+anom)
65    o consistent with addition of ptracer and ssh in pkg/profiles
66    o profiles: adding ptracer and ssh
67    o testreport: change multi-test output-file name
68      (from output.txt.{name} to output.{name}.txt)
69    o profiles: now ok for mutli-tiles case
70    o seaice: add 4 parameters for different advection schemes for area,
71      (effective) seaice thickness, enthalphy, and snow height. Their default
72      is the standard parameter SEAICEadvScheme
73    o calc_gw:
74     - add cosFacU in zonal viscous flux (harmonic.visc.).
75     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
76       of tutorial_plume_on_slope.
77    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
78    o calc_gw: true flux-form, account for horizontal grid spacing.
79      update rotating_tank results, but not plume_on_slope (affected at
80      truncation level, 11 digits).
81    
82    checkpoint58l_post
83    o calc_gw:
84     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
85     - remove side-drag for now (need to fix it); update plume_on_slope results.
86     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
87    o commit code to make SST/SSS weights spatially variable
88      (based on either variable in-situ or variable initial T/S weights)
89    o pkg/ecco:
90      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
91        now based on horizontally varying weights wthetaLev, wsaltLev
92      * cost_averagesflags now returns year indices in addition to day, month
93      * sflux balance is performed on annual basis
94        (sflxumm, sfluxmm2, bal_sfluxmm)
95      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
96        including separate counting and multipliers
97    o pkg/rbcs
98      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
99    
100    checkpoint58k_post
101    o testreport:
102     - always build in dir. "build" (if not there, mkdir build instead of building
103       & running in input)
104     - run in dir run (if it exists), in build otherwise.
105     - call prepare_run (if input/prepare_run exists)
106     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
107    o pkg/exf modifications to interpolation and rotation routines for more
108       reasonable treatment of North Pole singularity: for tracers North Pole
109       value is set to northernmost zonal-mean value, for zonal velocity it is
110       set to zero, and for meridional velocity it is set to northernmost value.
111    o pkg/exf/exf_check_range.F
112     - add tile index to diagnostics and move stop statement to the very
113       end of the routine.
114    o pkg/diagnostics: (diagnostics_main_init.F)
115      define title of isomorphic variables according to the current config.
116    o pkg/thsice with pkg/seaice dynamics:
117    - fix domain of computation (interior only, required for exf) and do exchanges
118    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
119    o towards a standard way of dealing with multi-threading in MONITOR
120      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
121    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
122       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
123    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
124    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
125    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
126       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
127    o tracer advection:
128     - clean-up and simplify calc_common_factors.F
129     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
130       advection subroutine (but still not used within DST advection S/R)
131    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
132    
133    checkpoint58j_post
134    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
135      from file (collects calls previously in FORWARD_STEP)
136    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
137    o adjoint store dir. adjusted accordingly
138    o genmake2
139      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
140    
141    checkpoint58i_post
142    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
143      on wind stress (SEAICEstressFactor defaults to 1.)
144    o Total number of Timers is finite (<=40): comment out 2 non-essential one
145      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
146    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
147      on CS-grid: no longer loosing mass.
148    o exf & curvilinear-grid: no longer modify longitude xC & xG.
149  o pkg/ggl90: fix sloppy output and fix a bug  o pkg/ggl90: fix sloppy output and fix a bug
