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

168    o some bug fixes for #undef REAL4_IS_SLOW
169    
170    checkpoint52 = ecco_c52_e35
171    o after testing adjoints of checkpoint51u_post
172    
173    checkpoint51u_post
174    o this is the post-merge tag of the ecco-branch
175      (needs another clean checkout and re-testing)
176    o various natl_box_adjoint configs and results
177      but no input fields
178    o obcs adjoint not yet merged!
179    o adding ECCO global 1x1 and 2x2 degree configs
180    o updated/extended some store directives for seaice
181    o pkg/ecco now containes ecco-specific part of cost function
182    o top level routines the_main_loop, forward_step
183      supersede those in model/src/
184      previous input data.cost now in data.ecco
185      (new namelist ecco_cost_nml)
186    o in ctrl/ cleaned some cross-dependencies and updated CPP options
187    
188    checkpoint51t_post
189    o this is the pre-merge tag of the ecco-branch
190    
191    checkpoint51s_post
192    o cleanup: removed various obsolete #define-s
193    o pkg/grdchk
194      - renamed 'ph-grd 3' to 'grad-res'
195      - merged from ecco-branch
196        (remaining bug fixes for obcs gradient checks)
197      - additional high-precision output for testreport
198        (grep for 'precision_grdchk_result')
199    
200    checkpoint51r_post
201    o cleaned up or removed CPP_OPTIONS.h files
202    o updated results for some of the tests to reflect the new
203      optfiles (-ieee: -O0 instead of -O3)
204    
205    checkpoint51q_post
206    o cd_code:
207      - moved cd_scheme.F -> cd_code_scheme.F
208      - separate read_checkpoint from cd_code_ini_vars.F
209      - separated cd_code part from write_checkpoint
210      - updated AD_SOURCE, generated .flow
211      - added CD_CODE_VARS.h to the_main_loop
212      - Moving cd_code specific store dir.s to pkg/cd_code
213    o ctrl package totally restructured
214      - pack/unpack now optional and decoupled from
215        xx_/adxx_ I/O
216      - ctrl_pack/unpack cleaned
217        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
218      - confined inclusion of AD_CONFIG.h to where necessary.
219    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
220    
221    checkpoint51p_post
222    o create initial cd_code package
223      - WARNING: the initialization of fields within packages
224        is broken because INI_FIELDS (where READ_CHECKPOINT is
225        called) is called *before* PACKAGES_INIT_VARIABLES.
226        This seems to be backwards since
227        1) its important to initially zero the entire field including
228           the "halo" region
229        2) zeroing needs to be done *before* reading pickup info
230           and the pickup call might or might not happen in any
231           particular run
232      - this needs an overhaul for R2
233    o cleanup verification/*/code/GMREDI_OPTIONS.h
234    o cleanup testreport
235

244    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
245    o bug fix in find_alpha.F for MDJWF:
246      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
247        change rho -> rho-rhoConst
248      - replace call find_rho to find_rhonum
249    o initialisation of rFlx extended to full array (required by TAF)
250      and shifted to thermodynamics
251    o removed PTRACERS.h in ptracers routine
252    o added surfacetendencyPtr to S/R parameter list pracers_forcing

270        (this means new output.txt for global_ocean.90x40x15,
271         global_ocean.cs32x15, and global_with_exf)
272    o added surface flux output variables to TIMEAVE_STATVARS
273    
274    checkpoint51n_pre
275    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

417    
418    checkpoint51a_post
419    o added code for biogeochemistry package
420      - new pkgs: dic, gchem
421      - new subroutine in ptracers
422    o modify code for biogeo packages
423      - in model/src and pkg/ptracers
424    
425    checkpoint51
426    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
427      - autodiff, ctrl, exf, grdchk, seaice
428      kept separate packages
429      - cost, ecco, obcs
430    o updating verification/internal_wave, verification/lab_sea
431      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
432    
433    checkpoint50i_post
434    o Preparing next differentiable checkpoint and sync
435      of MAIN vs. ecco-branch
436      - 1st step: this one is differentiable
437      - 2nd step: next(! not this) checkpoint will have updated packages
438                  from ecco-branch)
439    
440    checkpoint50h_post
441    o new package "land": provide surface BC for AIM.
442    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
443    o AIM: use true log-P extrapolation for near surface temp (= as in
444        F.Molteni paper) ; update aim.5l_cs output.
445    o New variable in PARM03 for more flexible pickups
446    o somewhat cleaned package initialisation sequence for
447      ctrl/ cost/ ecco/ in packages_... routines
448    
449    checkpoint50g_post
450    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
451      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
452      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
453        made the default because of faster convergence than ADI
454    
455    checkpoint50f_post
456    o exf totally restructured
457      - replaced all exf_set_ routines by one generic exf_set_gen.F
458        and made sure it's still differentiable
459      - split exf_getffields.F into new exf_bulkformulae.F
460      - exf_inscal_/exf_outscal_ suffixes consistent with field names
461      - updated adjoint/makefile and relevant verif. accordingly
462    
463    checkpoint50f_pre
464     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
465          + change Evap over land. (update aim.5l_cs output)
466     o added missing .cvsignores and made uniform across expts
467     o changed configuration of tidal_basin_2d expt
468     o added pkg/debug functions for tracing code in fatal crashes
469     o tidied pkg/monitor to use MONITOR_OPTIONS.h
470     o new fn in pkg/monitor to stop model if solution grows too big
471     o removed lots of single quotes from comments
472    
473  checkpoint50e_post  checkpoint50e_post
474  o make KPP work with PTRACERS  o make KPP work with PTRACERS
