4      ==============================      ==============================
5    
6    checkpoint52l_pre
7    
8    o fix problem (when 1 tile is empty) in min/max monitor.
9    o fix bug in timeAve (u,vZetatave in common block)
10    o no restoring terms under ice for pkg/seaice
11    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
12    o bug fix for pkg/seaice pickups
13    o change MNC call locations and add coordinate attributes
14    o mask vorticity at the corner ; affects global_ocean.cs output
15    o fix ini_curvilinear_grid ; test CS experiments with mpi
16    o aim.5l_cs: modify sea-ice fraction input file ; update output
17    o exf: Adding simple range check routine for exf fields after read
18    
19    checkpoint52k_post
20    o removed top-level directory "diags"
21      - we migrated these functions to pkg/timeave a long time ago
22    o fixed bug introduced in pkg/monitor
23    o accuracy ctrlprec = 32 insuffient for gradient checks using
24      averaged fields (I/O via cost_averages)
25      -> use ctrl.h in active_file*.F to control I/O precision.
26    o paramter list of CALL ADTHE_MAIN_LOOP
27    o added initial do_the_model_io to ecco
28    o set all ...Freq to zero after cost_final
29      taveFreq, dumpFreq, pChkptFreq
30    o MAIN and ECCO differentiability restored
31    
32    checkpoint52j_post
33    o fix nchklev in tamc.h for global_ocean...
34    o Bringing flow and store directives up-to-date
35    o Really weird thing!
36      call do_the_model_io from the_main_loop with parameters
37      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
38      TAF places a faulty re-call of initialise_varia
39      after cost_final call which should not be there!
40    checkpoint52j_pre
41    
42    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
43      error messages
44    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
45    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
46      debug output
47    o modfied mdsio_writefield.F to handle non-global files under exch2
48    o update AIM Cubed-Sphere exp (aim.5l_cs):
49      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
50    o update AIM Equatorial Channel exp:
51      use standard aim_v23 pkg and change the SST fields to be more realistic.
52    o globalFile now works with exch2
53    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
54      mon_vort3.F to make exch2 friendly with >1 tile per cube face
55    o limit timeave output for hi-res integrations
56    
57    checkpoint52i_post
58    o removed CPP_EEOPTIONS.h from verification/*/code
59    o updated the tiling for global_ocean_pressure
60    checkpoint52i_pre
61    
62    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
63      the old pkg/aim).
64    
65    checkpoint52h_pre
66    o shortened offending lines in exch2_send_rx?.template
67    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
68    o genmake2: add build & execute test for NetCDF code
69    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
70      old grid files, moved CPP_EEMACROS.h to pkg/exch2
71    o added useSingleCPUIO flag to monitor.F and mon_out.F
72    o added temporary hack for sea-ice dynamics on the cube:
73      metric terms are ignored and it is assumed that
74      there is no sea-ice on cube faces 1, 2, 4, and 5.
75    
76    checkpoint52f_post
77    o added exch2 cube routines to pkg/exch2
78    o modified hs94.cs-32x32x5 to use it
79    o added new grid files to hs94.cs-32x32x5
80    checkpoint52f_pre
81    
82    checkpoint52e_post
83    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
84      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
85    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
86      to work with implicit vertical advection and AB ;
87    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
88    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
89     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
90    checkpoint52e_pre
91    
92    o fix bug in impldiff when Nr=1 or Nr=2.
93    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
94    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
95    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
96      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
97    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
98    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
99    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
100    
101    checkpoint52d_post
102    o re-tiled many expts to allow comparison in multi-processor mode
103      - updated output accordingly
104      - changed hs94.128x64x5 to use intial T from file rather than use the
105        random number generator
106    o add infrastructure in model routines for fizhi and gridalt packages
107    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
108    o changes to permit hi-res, cubed-sphere, configuration
109      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
110      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
111      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
112        of surface winds for the cube
113      (A verification experiment, based on global_ocean.cs32x15, but with
114       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
115       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
116       complete with example surface forcing files and matlab scripts to look
117       at the output and compare it with that of global_ocean.cs32x15.)
118    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
119       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
120       to conform to the common rule.
121    o check-in the first version of the coupler + interfaces for multi-components
122       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
123       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
124       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
125       - ocean and atmos. share the same horizontal grid (no interpolation).
126       - exchanges between component and coupler is done in forward_step
127    o new verification experiment, cpl_aim+ocn:
128       coupled ocean - AIM atmosphere on cs32 grid.
129    
130    checkpoint52d_pre
131    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
132    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
133    
134    checkpoint52c_post
135    o Fixing OPTIONS files for use of exf:
136      - ALLOW_ECCO not needed
137      - ECCO_CPPOPTIONS.h should not be included from
138        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
139        as has been the case in the past
140      - All cal/exf related options are currently set in
141        single header file. Should remain so until we
142        agree on a consistent new policy.
143    o Removed all CPP options for cal package.
144      cal has no more CPP options.
145    o modified STOREs in GAD_ADVECTION
146    o corrected key comp. for passkey
147    
148    checkpoint52b_post
149    o new version: "thsice" of thermodynamic sea-ice pkg:
150     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
151     - modify fluxes but do not change theta directly;
152     - light cleaning of bulk_force pkg (still needed with thsice).
153     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
154       + output_thsice.txt to test thsice & bulk_force pkgs.
155    o put back grid & coriolis monitor output.
156    checkpoint52b_pre
157    
158    o call "do_the_model_io" at the beginning (=> dump initial state)
159    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
160    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
161      (need info on NUMBER_OF_PTRACERS)
162    o missing PTRACERS headers in some routines
163    o default tamc.h in pkg/autodiff supposed to crash
164      to ensure proper customization
165    
166    checkpoint52a_post
167    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
168      - moved surfaceTendencyTice from pkg/seaice to main code
169      - subroutine FREEZE_SURFACE now limits only surface temperature
170        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
171        => new output.txt for global_ocean.cs32x15 & global_with_exf
172      - keep the old version of FREEZE for backward compatibility;
173        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
174      - corresponding modifs for TAF directives
175    o added surface flux output variables to TIMEAVE_STATVARS
176    o time-averaged output for pkg/ptracers

182    o some bug fixes for #undef REAL4_IS_SLOW
183    
184    checkpoint52 = ecco_c52_e35
185    o after testing adjoints of checkpoint51u_post
186    
187    checkpoint51u_post
188    o this is the post-merge tag of the ecco-branch
189      (needs another clean checkout and re-testing)
190    o various natl_box_adjoint configs and results
191      but no input fields
192    o obcs adjoint not yet merged!
193    o adding ECCO global 1x1 and 2x2 degree configs
194    o updated/extended some store directives for seaice
195    o pkg/ecco now containes ecco-specific part of cost function
196    o top level routines the_main_loop, forward_step
197      supersede those in model/src/
198      previous input data.cost now in data.ecco
199      (new namelist ecco_cost_nml)
200    o in ctrl/ cleaned some cross-dependencies and updated CPP options
201    
202    checkpoint51t_post
203    o this is the pre-merge tag of the ecco-branch
204    
205    checkpoint51s_post
206    o cleanup: removed various obsolete #define-s
207    o pkg/grdchk
208      - renamed 'ph-grd 3' to 'grad-res'
209      - merged from ecco-branch
210        (remaining bug fixes for obcs gradient checks)
211      - additional high-precision output for testreport
212        (grep for 'precision_grdchk_result')
213    
214    checkpoint51r_post
215    o cleaned up or removed CPP_OPTIONS.h files
216    o updated results for some of the tests to reflect the new
217      optfiles (-ieee: -O0 instead of -O3)
218    
219    checkpoint51q_post
220    o cd_code:
221      - moved cd_scheme.F -> cd_code_scheme.F
222      - separate read_checkpoint from cd_code_ini_vars.F
223      - separated cd_code part from write_checkpoint
224      - updated AD_SOURCE, generated .flow
225      - added CD_CODE_VARS.h to the_main_loop
226      - Moving cd_code specific store dir.s to pkg/cd_code
227    o ctrl package totally restructured
228      - pack/unpack now optional and decoupled from
229        xx_/adxx_ I/O
230      - ctrl_pack/unpack cleaned
231        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
232      - confined inclusion of AD_CONFIG.h to where necessary.
233    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
234    
235    checkpoint51p_post
236    o create initial cd_code package
237      - WARNING: the initialization of fields within packages
238        is broken because INI_FIELDS (where READ_CHECKPOINT is
239        called) is called *before* PACKAGES_INIT_VARIABLES.
240        This seems to be backwards since
241        1) its important to initially zero the entire field including
242           the "halo" region
243        2) zeroing needs to be done *before* reading pickup info
244           and the pickup call might or might not happen in any
245           particular run
246      - this needs an overhaul for R2
247    o cleanup verification/*/code/GMREDI_OPTIONS.h
248    o cleanup testreport
249

258    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
259    o bug fix in find_alpha.F for MDJWF:
260      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
261        change rho -> rho-rhoConst
262      - replace call find_rho to find_rhonum
263    o initialisation of rFlx extended to full array (required by TAF)
264      and shifted to thermodynamics
265    o removed PTRACERS.h in ptracers routine
266    o added surfacetendencyPtr to S/R parameter list pracers_forcing

285         global_ocean.cs32x15, and global_with_exf)
286    o added surface flux output variables to TIMEAVE_STATVARS
287    
288    checkpoint51n_pre
289    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

313       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
314    
315    checkpoint51k_post
316    o change default to: useNHMTerms=.FALSE.

342    
343    checkpoint51i_post
344    o merge of the branch-genmake2

416      (relevant for cluster I/O to local disk)
417    `
418    >>>checkpoint51b_post
419    adjoint of ptracers
420    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
421    o extended state in checkpoint_lev?, etc.
422    o alternative ctrl/cost with tr1 or ptracer
423    o new comlev1_bibj_ptracers
424    o new ptracers.flow
425    o made ptracers_forcing same as external_forcing_s
426    o added verification for adjoint with ptracers
427      - adm. grdchk fail so far
428      - tlm. grdchk OK
429      - checked tapelev/comlev recomputations: OK
430    <<<checkpoint51b_pre
431    
432    checkpoint51a_post
433    o added code for biogeochemistry package
434      - new pkgs: dic, gchem
435      - new subroutine in ptracers
436    o modify code for biogeo packages
437      - in model/src and pkg/ptracers
438    
439    checkpoint51
440    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
441      - autodiff, ctrl, exf, grdchk, seaice
442      kept separate packages
443      - cost, ecco, obcs
444    o updating verification/internal_wave, verification/lab_sea
445      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
446    
447    checkpoint50i_post
448    o Preparing next differentiable checkpoint and sync
449      of MAIN vs. ecco-branch
450      - 1st step: this one is differentiable
451      - 2nd step: next(! not this) checkpoint will have updated packages
452                  from ecco-branch)
453    
454    checkpoint50h_post
455    o new package "land": provide surface BC for AIM.
456    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
457    o AIM: use true log-P extrapolation for near surface temp (= as in
458        F.Molteni paper) ; update aim.5l_cs output.
459    o New variable in PARM03 for more flexible pickups
460    o somewhat cleaned package initialisation sequence for
461      ctrl/ cost/ ecco/ in packages_... routines
462    
463    checkpoint50g_post
464    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
465      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
466      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
467        made the default because of faster convergence than ADI
468    
469    checkpoint50f_post
470    o exf totally restructured
471      - replaced all exf_set_ routines by one generic exf_set_gen.F
472        and made sure it's still differentiable
473      - split exf_getffields.F into new exf_bulkformulae.F
474      - exf_inscal_/exf_outscal_ suffixes consistent with field names
475      - updated adjoint/makefile and relevant verif. accordingly
476    
477  checkpoint50f_pre  checkpoint50f_pre
478   o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;   o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
479        + change Evap over land. (update aim.5l_cs output)        + change Evap over land. (update aim.5l_cs output)
