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

137  checkpoint58g_post  checkpoint58g_post
138    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
139       used for mean seasonal cycle, mean diurnal cycle); add an example
140       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
141  o pkg/ggl90:  o pkg/ggl90:
142    - add parameter (minimum surface kinetic energy)    - add parameter (minimum surface kinetic energy)
