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

151  checkpoint58g_post  checkpoint58g_post
152    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
153       used for mean seasonal cycle, mean diurnal cycle); add an example
154       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
