4      ==============================      ==============================
5    o thermodynamics sea-ice (thsice) is now tested with testreport.
6    o test exp. advect_cs: use the standard cs32 grid ; update output.
7    
8    checkpoint52l_post
9    o new land formulation:
10      a) use ground enthalpy as prognostic variable to ensure exact
11         energy conservation.
12      b) account for water temperature and for latent heat of freezing
13         in all processes (rain, run-off, ground storage)
14      c) compute surface and ground temperature implicitly.
15    o aim_v23 modification for new land model:
16      a) Treat separately land / ocean / sea-ice surface fluxes
17         to allow implicit computation of land & sea-ice surface temp.
18      b) add snow precipitation.
19    checkpoint52l_pre
20    
21    o fix problem (when 1 tile is empty) in min/max monitor.
22    o fix bug in timeAve (u,vZetatave in common block)
23    o no restoring terms under ice for pkg/seaice
24    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
25    o bug fix for pkg/seaice pickups
26    o change MNC call locations and add coordinate attributes
27    o mask vorticity at the corner ; affects global_ocean.cs output
28    o fix ini_curvilinear_grid ; test CS experiments with mpi
29    o aim.5l_cs: modify sea-ice fraction input file ; update output
30    o exf: Adding simple range check routine for exf fields after read
31    
32    checkpoint52k_post
33    o removed top-level directory "diags"
34      - we migrated these functions to pkg/timeave a long time ago
35    o fixed bug introduced in pkg/monitor
36    o accuracy ctrlprec = 32 insuffient for gradient checks using
37      averaged fields (I/O via cost_averages)
38      -> use ctrl.h in active_file*.F to control I/O precision.
39    o paramter list of CALL ADTHE_MAIN_LOOP
40    o added initial do_the_model_io to ecco
41    o set all ...Freq to zero after cost_final
42      taveFreq, dumpFreq, pChkptFreq

44    
45    checkpoint52j_post
46    o fix nchklev in tamc.h for global_ocean...
47    o Bringing flow and store directives up-to-date
48    o Really weird thing!
49      call do_the_model_io from the_main_loop with parameters
50      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
51      TAF places a faulty re-call of initialise_varia
52      after cost_final call which should not be there!
53    checkpoint52j_pre
54    
55    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
56      error messages
57    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
58    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
59      debug output
60    o modfied mdsio_writefield.F to handle non-global files under exch2
61    o update AIM Cubed-Sphere exp (aim.5l_cs):
62      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
63    o update AIM Equatorial Channel exp:
64      use standard aim_v23 pkg and change the SST fields to be more realistic.
65    o globalFile now works with exch2
66    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
67      mon_vort3.F to make exch2 friendly with >1 tile per cube face
68    o limit timeave output for hi-res integrations
69    
70    checkpoint52i_post

72    o updated the tiling for global_ocean_pressure
73    checkpoint52i_pre
74    
75    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
76      the old pkg/aim).
77    
78    checkpoint52h_pre
79    o shortened offending lines in exch2_send_rx?.template
80    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
81    o genmake2: add build & execute test for NetCDF code
82    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
83      old grid files, moved CPP_EEMACROS.h to pkg/exch2
84    o added useSingleCPUIO flag to monitor.F and mon_out.F
85    o added temporary hack for sea-ice dynamics on the cube:
86      metric terms are ignored and it is assumed that
87      there is no sea-ice on cube faces 1, 2, 4, and 5.
88    
89    checkpoint52f_post
90    o added exch2 cube routines to pkg/exch2
91    o modified hs94.cs-32x32x5 to use it
92    o added new grid files to hs94.cs-32x32x5
93    checkpoint52f_pre
94    
95    checkpoint52e_post
96    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
97      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
98    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
99      to work with implicit vertical advection and AB ;
100    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
101    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
102     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
103    checkpoint52e_pre
104    
105    o fix bug in impldiff when Nr=1 or Nr=2.
106    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
107    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
108    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
109      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

113    
114    checkpoint52d_post
115    o re-tiled many expts to allow comparison in multi-processor mode
116      - updated output accordingly
117      - changed hs94.128x64x5 to use intial T from file rather than use the
118        random number generator
119    o add infrastructure in model routines for fizhi and gridalt packages
120    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
121    o changes to permit hi-res, cubed-sphere, configuration
122      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
123      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
124      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
125        of surface winds for the cube
126      (A verification experiment, based on global_ocean.cs32x15, but with
127       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
128       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
129       complete with example surface forcing files and matlab scripts to look
130       at the output and compare it with that of global_ocean.cs32x15.)
131    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
132       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
133       to conform to the common rule.
134    o check-in the first version of the coupler + interfaces for multi-components
135       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
136       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
137       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
138       - ocean and atmos. share the same horizontal grid (no interpolation).
139       - exchanges between component and coupler is done in forward_step
140    o new verification experiment, cpl_aim+ocn:
141       coupled ocean - AIM atmosphere on cs32 grid.
142    
143    checkpoint52d_pre
144    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
145    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
146    
147    checkpoint52c_post
148    o Fixing OPTIONS files for use of exf:
149      - ALLOW_ECCO not needed
150      - ECCO_CPPOPTIONS.h should not be included from
151        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
152        as has been the case in the past
153      - All cal/exf related options are currently set in
154        single header file. Should remain so until we
155        agree on a consistent new policy.
156    o Removed all CPP options for cal package.
157      cal has no more CPP options.
158    o modified STOREs in GAD_ADVECTION
159    o corrected key comp. for passkey
160    
161    checkpoint52b_post
162    o new version: "thsice" of thermodynamic sea-ice pkg:
163     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
164     - modify fluxes but do not change theta directly;
165     - light cleaning of bulk_force pkg (still needed with thsice).
166     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
167       + output_thsice.txt to test thsice & bulk_force pkgs.
168    o put back grid & coriolis monitor output.
169    checkpoint52b_pre
170    
171    o call "do_the_model_io" at the beginning (=> dump initial state)
172    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
173    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
174      (need info on NUMBER_OF_PTRACERS)
175    o missing PTRACERS headers in some routines
176    o default tamc.h in pkg/autodiff supposed to crash
177      to ensure proper customization
178    
179    checkpoint52a_post
180    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
181      - moved surfaceTendencyTice from pkg/seaice to main code
182      - subroutine FREEZE_SURFACE now limits only surface temperature
183        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
184        => new output.txt for global_ocean.cs32x15 & global_with_exf
185      - keep the old version of FREEZE for backward compatibility;
186        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

195    o some bug fixes for #undef REAL4_IS_SLOW
196    
197    checkpoint52 = ecco_c52_e35
198    o after testing adjoints of checkpoint51u_post
199    
200    checkpoint51u_post
201    o this is the post-merge tag of the ecco-branch
202      (needs another clean checkout and re-testing)
203    o various natl_box_adjoint configs and results
204      but no input fields
205    o obcs adjoint not yet merged!
206    o adding ECCO global 1x1 and 2x2 degree configs
207    o updated/extended some store directives for seaice
208    o pkg/ecco now containes ecco-specific part of cost function
209    o top level routines the_main_loop, forward_step
210      supersede those in model/src/
211      previous input data.cost now in data.ecco
212      (new namelist ecco_cost_nml)
213    o in ctrl/ cleaned some cross-dependencies and updated CPP options
214    
215    checkpoint51t_post
216    o this is the pre-merge tag of the ecco-branch
217    
218    checkpoint51s_post
219    o cleanup: removed various obsolete #define-s
220    o pkg/grdchk
221      - renamed 'ph-grd 3' to 'grad-res'
222      - merged from ecco-branch
223        (remaining bug fixes for obcs gradient checks)
224      - additional high-precision output for testreport
225        (grep for 'precision_grdchk_result')
226    
227    checkpoint51r_post
228    o cleaned up or removed CPP_OPTIONS.h files
229    o updated results for some of the tests to reflect the new
230      optfiles (-ieee: -O0 instead of -O3)
231    
232    checkpoint51q_post
233    o cd_code:
234      - moved cd_scheme.F -> cd_code_scheme.F
235      - separate read_checkpoint from cd_code_ini_vars.F
236      - separated cd_code part from write_checkpoint
237      - updated AD_SOURCE, generated .flow
238      - added CD_CODE_VARS.h to the_main_loop
239      - Moving cd_code specific store dir.s to pkg/cd_code
240    o ctrl package totally restructured
241      - pack/unpack now optional and decoupled from
242        xx_/adxx_ I/O
243      - ctrl_pack/unpack cleaned

245      - confined inclusion of AD_CONFIG.h to where necessary.
246    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
247    
248    checkpoint51p_post
249    o create initial cd_code package
250      - WARNING: the initialization of fields within packages
251        is broken because INI_FIELDS (where READ_CHECKPOINT is
252        called) is called *before* PACKAGES_INIT_VARIABLES.
253        This seems to be backwards since
254        1) its important to initially zero the entire field including
255           the "halo" region
256        2) zeroing needs to be done *before* reading pickup info
257           and the pickup call might or might not happen in any
258           particular run
259      - this needs an overhaul for R2
260    o cleanup verification/*/code/GMREDI_OPTIONS.h
261    o cleanup testreport
262    
263    checkpoint51o_post
264    o bringing AD-related verif's up to date with genmake2

270    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
271    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
272    o bug fix in find_alpha.F for MDJWF:
273      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
274        change rho -> rho-rhoConst
275      - replace call find_rho to find_rhonum
276    o initialisation of rFlx extended to full array (required by TAF)
277      and shifted to thermodynamics
278    o removed PTRACERS.h in ptracers routine
279    o added surfacetendencyPtr to S/R parameter list pracers_forcing

297        (this means new output.txt for global_ocean.90x40x15,
298         global_ocean.cs32x15, and global_with_exf)
299    o added surface flux output variables to TIMEAVE_STATVARS
300    
301    checkpoint51n_pre
302    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

324    o enable to apply restoring on S & T only in a latitude band.
325    o update output (external_forcing_surf modif. change truncation errors)
326       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
327    
328    checkpoint51k_post
329    o change default to: useNHMTerms=.FALSE.

355    
356    checkpoint51i_post
357    o merge of the branch-genmake2

414      - avoid "_d" constructs in PARAMETER declarations
415      - avoid interrupting lines by comment lines
416    o Use cluster local disks for purely local I/O
417      vs. globally visible disks needed for ctrl stuff
418      (merged from ecco-branch)
419      - new active_file_loc... and mdsio_..._loc routines
420      - affected packages: autodiff, ctrl, grdchk, mdsio
421    
422    checkpoint51c_post
423    o introducing integer flag debugLevel
424      - debLevZero: suppress all output
425      - debLevA: standard
426      - debLevB: equivalent to current debugMode=.TRUE.
427    o introducing pathname variable mdsioLocalDir for mdsio
428      that can be specified at runtime
429      (relevant for cluster I/O to local disk)
430    `
431    >>>checkpoint51b_post
432    adjoint of ptracers
433    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
434    o extended state in checkpoint_lev?, etc.
435    o alternative ctrl/cost with tr1 or ptracer
436    o new comlev1_bibj_ptracers
437    o new ptracers.flow
438    o made ptracers_forcing same as external_forcing_s
439    o added verification for adjoint with ptracers
440      - adm. grdchk fail so far
441      - tlm. grdchk OK
442      - checked tapelev/comlev recomputations: OK
443    <<<checkpoint51b_pre
444    
445    checkpoint51a_post
446    o added code for biogeochemistry package
447      - new pkgs: dic, gchem
448      - new subroutine in ptracers
449    o modify code for biogeo packages
450      - in model/src and pkg/ptracers
451    
452    checkpoint51
453    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
454      - autodiff, ctrl, exf, grdchk, seaice
455      kept separate packages
456      - cost, ecco, obcs
457    o updating verification/internal_wave, verification/lab_sea
458      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
459    
460    checkpoint50i_post
461    o Preparing next differentiable checkpoint and sync
462      of MAIN vs. ecco-branch
463      - 1st step: this one is differentiable
464      - 2nd step: next(! not this) checkpoint will have updated packages
465                  from ecco-branch)
