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

160    o some bug fixes for #undef REAL4_IS_SLOW
161    
162    checkpoint52 = ecco_c52_e35
163    o after testing adjoints of checkpoint51u_post
164    
165    checkpoint51u_post
166    o this is the post-merge tag of the ecco-branch
167      (needs another clean checkout and re-testing)
168    o various natl_box_adjoint configs and results
169      but no input fields
170    o obcs adjoint not yet merged!
171    o adding ECCO global 1x1 and 2x2 degree configs
172    o updated/extended some store directives for seaice
173    o pkg/ecco now containes ecco-specific part of cost function
174    o top level routines the_main_loop, forward_step
175      supersede those in model/src/
176      previous input data.cost now in data.ecco
177      (new namelist ecco_cost_nml)
178    o in ctrl/ cleaned some cross-dependencies and updated CPP options
179    
180    checkpoint51t_post
181    o this is the pre-merge tag of the ecco-branch
182    
183    checkpoint51s_post
184    o cleanup: removed various obsolete #define-s
185    o pkg/grdchk
186      - renamed 'ph-grd 3' to 'grad-res'
187      - merged from ecco-branch
188        (remaining bug fixes for obcs gradient checks)
189      - additional high-precision output for testreport
190        (grep for 'precision_grdchk_result')
191    
192    checkpoint51r_post
193    o cleaned up or removed CPP_OPTIONS.h files
194    o updated results for some of the tests to reflect the new
195      optfiles (-ieee: -O0 instead of -O3)
196    
197    checkpoint51q_post
198    o cd_code:
199      - moved cd_scheme.F -> cd_code_scheme.F
200      - separate read_checkpoint from cd_code_ini_vars.F
201      - separated cd_code part from write_checkpoint
202      - updated AD_SOURCE, generated .flow
203      - added CD_CODE_VARS.h to the_main_loop
204      - Moving cd_code specific store dir.s to pkg/cd_code
205    o ctrl package totally restructured
206      - pack/unpack now optional and decoupled from
207        xx_/adxx_ I/O

210      - confined inclusion of AD_CONFIG.h to where necessary.
211    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
212    
213    checkpoint51p_post
214    o create initial cd_code package
215      - WARNING: the initialization of fields within packages
216        is broken because INI_FIELDS (where READ_CHECKPOINT is
217        called) is called *before* PACKAGES_INIT_VARIABLES.
218        This seems to be backwards since
219        1) its important to initially zero the entire field including
220           the "halo" region
221        2) zeroing needs to be done *before* reading pickup info
222           and the pickup call might or might not happen in any
223           particular run
224      - this needs an overhaul for R2
225    o cleanup verification/*/code/GMREDI_OPTIONS.h
226    o cleanup testreport
227

236    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
237    o bug fix in find_alpha.F for MDJWF:
238      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
239        change rho -> rho-rhoConst
240      - replace call find_rho to find_rhonum
241    o initialisation of rFlx extended to full array (required by TAF)
242      and shifted to thermodynamics
243    o removed PTRACERS.h in ptracers routine

263         global_ocean.cs32x15, and global_with_exf)
264    o added surface flux output variables to TIMEAVE_STATVARS
265    
266    checkpoint51n_pre
267    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

292    
293    checkpoint51k_post
294    o change default to: useNHMTerms=.FALSE.

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