4      ==============================      ==============================
5    
6    o no restoring terms under ice for pkg/seaice
7    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
8    o bug fix for pkg/seaice pickups
9    o change MNC call locations and add coordinate attributes
10    o mask vorticity at the corner ; affects global_ocean.cs output
11    o fix ini_curvilinear_grid ; test CS experiments with mpi
12    o aim.5l_cs: modify sea-ice fraction input file ; update output
13    o exf: Adding simple range check routine for exf fields after read
14    
15    checkpoint52k_post
16    o removed top-level directory "diags"
17      - we migrated these functions to pkg/timeave a long time ago
18    o fixed bug introduced in pkg/monitor
19    o accuracy ctrlprec = 32 insuffient for gradient checks using
20      averaged fields (I/O via cost_averages)
21      -> use ctrl.h in active_file*.F to control I/O precision.
22    o paramter list of CALL ADTHE_MAIN_LOOP
23    o added initial do_the_model_io to ecco
24    o set all ...Freq to zero after cost_final
25      taveFreq, dumpFreq, pChkptFreq
26    o MAIN and ECCO differentiability restored
27    
28    checkpoint52j_post
29    o fix nchklev in tamc.h for global_ocean...
30    o Bringing flow and store directives up-to-date
31    o Really weird thing!
32      call do_the_model_io from the_main_loop with parameters
33      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
34      TAF places a faulty re-call of initialise_varia
35      after cost_final call which should not be there!
36    checkpoint52j_pre
37    
38    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
39      error messages
40    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
41    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
42      debug output
43    o modfied mdsio_writefield.F to handle non-global files under exch2
44    o update AIM Cubed-Sphere exp (aim.5l_cs):
45      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
46    o update AIM Equatorial Channel exp:
47      use standard aim_v23 pkg and change the SST fields to be more realistic.
48    o globalFile now works with exch2
49    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
50      mon_vort3.F to make exch2 friendly with >1 tile per cube face
51    o limit timeave output for hi-res integrations
52    
53    checkpoint52i_post
54    o removed CPP_EEOPTIONS.h from verification/*/code
55    o updated the tiling for global_ocean_pressure
56    checkpoint52i_pre
57    
58    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
59      the old pkg/aim).
60    
61    checkpoint52h_pre
62    o shortened offending lines in exch2_send_rx?.template
63    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
64    o genmake2: add build & execute test for NetCDF code
65    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
66      old grid files, moved CPP_EEMACROS.h to pkg/exch2
67    o added useSingleCPUIO flag to monitor.F and mon_out.F
68    o added temporary hack for sea-ice dynamics on the cube:
69      metric terms are ignored and it is assumed that
70      there is no sea-ice on cube faces 1, 2, 4, and 5.
71    
72    checkpoint52f_post
73    o added exch2 cube routines to pkg/exch2
74    o modified hs94.cs-32x32x5 to use it
75    o added new grid files to hs94.cs-32x32x5
76    checkpoint52f_pre
77    
78    checkpoint52e_post
79    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
80      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
81    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
82      to work with implicit vertical advection and AB ;
83    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
84    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
85     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
86    checkpoint52e_pre
87    
88    o fix bug in impldiff when Nr=1 or Nr=2.
89    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
90    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
91    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
92      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
93    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
94    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
95    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
96    
97    checkpoint52d_post
98    o re-tiled many expts to allow comparison in multi-processor mode
99      - updated output accordingly
100      - changed hs94.128x64x5 to use intial T from file rather than use the
101        random number generator
102    o add infrastructure in model routines for fizhi and gridalt packages
103    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
104    o changes to permit hi-res, cubed-sphere, configuration
105      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
106      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
107      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
108        of surface winds for the cube
109      (A verification experiment, based on global_ocean.cs32x15, but with
110       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
111       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
112       complete with example surface forcing files and matlab scripts to look
113       at the output and compare it with that of global_ocean.cs32x15.)
114    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
115       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
116       to conform to the common rule.
117    o check-in the first version of the coupler + interfaces for multi-components
118       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
119       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
120       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
121       - ocean and atmos. share the same horizontal grid (no interpolation).
122       - exchanges between component and coupler is done in forward_step
123    o new verification experiment, cpl_aim+ocn:
124       coupled ocean - AIM atmosphere on cs32 grid.
125    
126    checkpoint52d_pre
127    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
128    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
129    
130    checkpoint52c_post
131    o Fixing OPTIONS files for use of exf:
132      - ALLOW_ECCO not needed
133      - ECCO_CPPOPTIONS.h should not be included from
134        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
135        as has been the case in the past
136      - All cal/exf related options are currently set in
137        single header file. Should remain so until we
138        agree on a consistent new policy.
139    o Removed all CPP options for cal package.
140      cal has no more CPP options.
141    o modified STOREs in GAD_ADVECTION
142    o corrected key comp. for passkey
143    
144    checkpoint52b_post
145    o new version: "thsice" of thermodynamic sea-ice pkg:
146     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
147     - modify fluxes but do not change theta directly;
148     - light cleaning of bulk_force pkg (still needed with thsice).
149     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
150       + output_thsice.txt to test thsice & bulk_force pkgs.
151    o put back grid & coriolis monitor output.
152    checkpoint52b_pre
153    
154    o call "do_the_model_io" at the beginning (=> dump initial state)
155    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
156    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
157      (need info on NUMBER_OF_PTRACERS)
158    o missing PTRACERS headers in some routines
159    o default tamc.h in pkg/autodiff supposed to crash
160      to ensure proper customization
161    
162    checkpoint52a_post
163    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
164      - moved surfaceTendencyTice from pkg/seaice to main code
165      - subroutine FREEZE_SURFACE now limits only surface temperature
166        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
167        => new output.txt for global_ocean.cs32x15 & global_with_exf
168      - keep the old version of FREEZE for backward compatibility;
169        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
170      - corresponding modifs for TAF directives
171    o added surface flux output variables to TIMEAVE_STATVARS
172    o time-averaged output for pkg/ptracers

178    o some bug fixes for #undef REAL4_IS_SLOW
179    
180    checkpoint52 = ecco_c52_e35
181    o after testing adjoints of checkpoint51u_post
182    
183    checkpoint51u_post
184    o this is the post-merge tag of the ecco-branch
185      (needs another clean checkout and re-testing)
186    o various natl_box_adjoint configs and results
187      but no input fields
188    o obcs adjoint not yet merged!
189    o adding ECCO global 1x1 and 2x2 degree configs
190    o updated/extended some store directives for seaice
191    o pkg/ecco now containes ecco-specific part of cost function
192    o top level routines the_main_loop, forward_step
193      supersede those in model/src/
194      previous input data.cost now in data.ecco
195      (new namelist ecco_cost_nml)
196    o in ctrl/ cleaned some cross-dependencies and updated CPP options
197    
198    checkpoint51t_post
199    o this is the pre-merge tag of the ecco-branch
200    
201    checkpoint51s_post
202    o cleanup: removed various obsolete #define-s
203    o pkg/grdchk
204      - renamed 'ph-grd 3' to 'grad-res'
205      - merged from ecco-branch
206        (remaining bug fixes for obcs gradient checks)
207      - additional high-precision output for testreport
208        (grep for 'precision_grdchk_result')
209    
210    checkpoint51r_post
211    o cleaned up or removed CPP_OPTIONS.h files
212    o updated results for some of the tests to reflect the new
213      optfiles (-ieee: -O0 instead of -O3)
214    
215    checkpoint51q_post
216    o cd_code:
217      - moved cd_scheme.F -> cd_code_scheme.F
218      - separate read_checkpoint from cd_code_ini_vars.F
219      - separated cd_code part from write_checkpoint
220      - updated AD_SOURCE, generated .flow
221      - added CD_CODE_VARS.h to the_main_loop
222      - Moving cd_code specific store dir.s to pkg/cd_code
223    o ctrl package totally restructured
224      - pack/unpack now optional and decoupled from
225        xx_/adxx_ I/O
226      - ctrl_pack/unpack cleaned
227        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
228      - confined inclusion of AD_CONFIG.h to where necessary.
229    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
230    
231    checkpoint51p_post
232    o create initial cd_code package
233      - WARNING: the initialization of fields within packages
234        is broken because INI_FIELDS (where READ_CHECKPOINT is
235        called) is called *before* PACKAGES_INIT_VARIABLES.
236        This seems to be backwards since
237        1) its important to initially zero the entire field including
238           the "halo" region
239        2) zeroing needs to be done *before* reading pickup info
240           and the pickup call might or might not happen in any
241           particular run
242      - this needs an overhaul for R2
243    o cleanup verification/*/code/GMREDI_OPTIONS.h
244    o cleanup testreport
245

254    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
255    o bug fix in find_alpha.F for MDJWF:
256      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
257        change rho -> rho-rhoConst
258      - replace call find_rho to find_rhonum
259    o initialisation of rFlx extended to full array (required by TAF)
260      and shifted to thermodynamics
261    o removed PTRACERS.h in ptracers routine

281         global_ocean.cs32x15, and global_with_exf)
282    o added surface flux output variables to TIMEAVE_STATVARS
283    
284    checkpoint51n_pre
285    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
