3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o clean up build options files for SunOS, in particular
7      - remove -traditional from xmakedepend
8      - change -xarch=v9 to -xarch=native for f77
9      - restore use of make (not gmake)
10      - add CC=gcc if using g77
11    o changes per discussion of AM, JMC, & EH3 today:
12      - move redundant "grid" variables out of "state" -- in preparation of
13        creating proper CF-style coordinate variables and in recognition
14        that any/all grid variables can be easily copied (eg. w/NCO) from
15        the grid files into any of the other NetCDF files
16      - *always* output grid variables with MDSIO (this will eventually be
17        changed)
18      - output MNC grid file if useMNC is true
19    o every instance of _END_MASTER() has been found and replaced with
20      _END_MASTER( myThid ) in order to satisfy certain picky Sun
21      preprocessors
22    o re-arrange diagnostics pkg initialisation:
23     - allow each package to extend the available diagnostics list
24     - add some checking and fix small problems (multi-threaded, ...)
25     - new S/R diagnostics_fill (replace fill_diagnostics):
26       look through the short list of active diag. (instead of the long list)
27       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
28    
29    checkpoint57a_post
30    o this set of changes restores TAMC compatibility
31      tested for global_ocean.90x40x15 adjoint on trough
32      (what a pain)
33    
34    checkpoint57a_pre
35    o some modifs in tools/build_options for sunos
36    o call ctrl_pack for ctrl at end for optimcycle=0
37    
38    checkpoint57
39    o add horizontal bi-harmonic viscosity for vertical velocity
40      - new parameter viscA4W (defaults to viscA4)
41      - affects only non-hydrostatic code
42      - to be done: no-slip lateral boundary conditions
43    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
44    o implement Implicit Vertical advection for pTracers
45    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
46      (implemented also for implicit vertical diffusion & advection)
47    o OBCS: extend application of tracer open boundary conditions
48      to a strip beyond the boundary of width Olx/Oly
49    o add call monitor to TAF set of required calls (flow directives)
50      and include in natl_box_adjoint
51    o untangle a few ifdefs related to cost, ctrl, autodiff
52      untangel a few ALLOW_ECCO_OPTIMIZATION
53    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
54      (theta2, salt2 in ecco_cost_weights)
55    
56    checkpoint56c_post
57    o OBCS as control variables
58      - update ctrl_ad_diff.list, obcs_ad_diff.list
59      - remove balance of obcs controls from default
60      - fix index bug nobcs in ctrl_init
61      - fix dummy fields filen in ctrl_pack
62      - add dummy weights for obcs
63    o lsopt: comment out fort.94 output
64    o optim:
65      - remove unnecessary header files
66      - adjusted namelists
67      - add xerbla.F to Makefile
68    o exf:
69      - multiple modifications of exf_check_range
70      - unit change in exf_init_runoff from [m/year] to [m/s]
71    o mdsio:
72      - i/o-vector change debugLevel from debLevA to debLevB
73    
74    checkpoint56b_post
75    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
76      is called from DO_THE_MODEL_IO
77      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
78      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
79      - clean up PTRACERS_WRITE_TIMEAVE a little
80    o add another verification experiment that tests both the cfc-pkg and
81      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
82      reactive tendencies treated inline with regular timestepping
83    o testreport previously did a lousy job of comparing small numbers, so
84      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
85      implemented in the little c-progam tmp_cmpnum.c which is embedded in
86      testreport.
87    o ptracers_monitor: bug fix for MPI
88    
89    checkpoint56a_post
90    o GCHEM: finish reorganizating the package
91      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
92        (introduces another 3D-array for each passive tracer, but only if
93        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
94        gchemTendency is not needed because the timestep is done separately)
95      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
96      - GCHEM is now---more or less cleanly---separate from PTRACERS
97      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
98        so clear to me how that should be done in a general way.
99    o CFC: improve formatting of output in CFC_ATMOS
100    o PTRACERS:
101      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
102        that ALL experiments with ptracers enable can be checked. This makes
103        GCHEM_MONITOR obsolete.
104      - include a runtime parameter PTRACERS_monitorFreq that defaults to
105        monitorFreq
106      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
107    o add PTRACERS (PTR0[1-5]) to testreport output
108    o exf_check_range:
109      * default changed to .TRUE.
110      * will check values for niter0 if debLevA, every timestep if debLevB
111      * STOP in exf_check_range if 'out of range'
112      * range chosen generous to allow for potential extema
113      TBD: a version with stricter range
114           permitted range would be runtime parameters
115    o GMredi:
116      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
117      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
118      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
119    o GCHEM:
120      - move call to GCHEM_FORCING_SEP, so that it is now called before
121        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
122      - introduced a useGCHEM runtime flag and applied it everywhere.
123      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
124        this flag is now only visible within GCHEM-pkg routines.
125      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
126        be replaced by a 3D array that is computed before thermodynamics; for
127        this, the tracer ID iTracer had to be included into the parameter list
128        of ptracers_forcing
129      - set up forward_step to call gchem_forcing, that will replace
130        gchem_forcing_int in ptracers_forcing
131      - cleaning up
132    o small cleaning of exch2: remove files that are also in eesupp/src
133    
134    checkpoint56
135    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
136    o mnc: cleanup "full" files--fixes out-of-memory problem
137    o ECCO-GODAE
138      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
139      * fully merged and updated from SIO code
140        windstress sign change affects
141        - exf_inscal_[u/v]stress
142        - sign of xx_tau[u/v] adjustments
143        - signs in cost_scat
144      * ctrl_get_gen: avoid update of tau[u/v] for first few days
145      * natl_box_adjoint updated and compressed
146      * 2-level checkpoint switch added
147        (tested in EXP. 1 of natl_box_adjoint)
148      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
149    o SVD
150      * first complete, non-hacked version for SVD calculations
151      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
152        performed via direct access files admtlm_vector.it????
153        (via ctrl_[un]pack)
154      * optimcycle is used for ARPACK iteration counter
155        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
156      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
157        and add linear transforms where necessary
158      * controls are initial/final SST, SSS (can be extended; need to check
159        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
160    o mdsio: filename info to both stderr, stdout
161    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
162      from sign change
163    
164    checkpoint55j_post
165    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
166      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
167    o add consistent build directories and .cvsignore files to verification
168    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
169  o make all subroutines 30 or less characters in length for certain older  o make all subroutines 30 or less characters in length for certain older
