3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  checkpoint53b_pre
7    
8    o created pkg/mom_common in preparation for variable viscosity code
9    o renamed and split ini_mnc_io
10    o pkg/land: only liquid water can diffuse or run-off
11    o AIM using land: soil wetness availability account for snow
12    o added printMapIncludesZeros to EEPARMS namelist
13    
14    checkpoint53a_post
15    o restore TAMC compatiility for exf_constants.h
16      (no usage of _d in .h)
17    o Additional storing in KPP in an attempt to fix
18      TAMC problem with adjoint of KPP code.
19      (no success...)
20      Identical code works fine with TAF.
21    o Fixed verification/natl_box_adjoint experiments.
22      Initial conditions for Experiments 4 and 5 are now
23      set to "SEAICE_initialHEFF=0", which is more reasonable,
24      and hence gives results closer to that of Experiment 2.
25      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
26    
27    checkpoint53
28    o stable checkpoint with up to date adjoint
29      TLM tests only run for 1st grdchk at the moment. Its unclear if
30      this is a code problem or a problem with resetting code for g_
31      variables that is being autogenerated wrong.
32      Otherwise:
33       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
34       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
35         are both still in chaos following their security messes.
36    
37    checkpoint52n_post
38    o various build (mostly genmake2) changes including:
39      - ability to build/run more easily within Cygwin and MacOS X
40      - more complicated Makefiles with a stronger dependence on Gnu Make
41    o pkg/seaice modifications
42      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
43        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
44        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
45      - changed proxy for geostrophic velocity and updated
46        verification/lab_sea/results/* accordingly
47      - removed ADI dynamic solver from pkg/seaice
48      - replaced all occurrences of 1/CSTICE or 1/CSUICE
49        they caused a segmentation fault under certain circumstances
50      - removed unused field WATR
51    o bug fix in exf-package:
52      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
53         now reflect that.
54    o small fixes in the cal-package:
55      - set reference date to first of January for the 'model'-calendar
56      - failing of cal_CheckDate in cal_FullDate now actually results in a
57        warning
58    o small modifications in exf-package to increase flexibility:
59      - change climtempfreeze from a constant to a runtime parameter that
60        is specified in data.exf_clim (default = -1.9)
61      - introduce runtime parameter windstressmax (default = 2.0) that is
62        specified in data.exf
63    o fix in pkg/thsice:
64      - update Evap (Tsf changes) to be consistent with Latent heat flux
65      - maintain snow precipitation unchanged (even if Tsf >=0).
66     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
67    
68    checkpoint52m_post
69    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
70      this does not change any of the results, because myIter=0 in swfrac always
71      lead to jwtype=2 (the default anyway), but the call makes little sense
72      as a default
73    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
74    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
75      atmospheric model (AIM) to use it ; add a "slab ocean" component.
76    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
77    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
78    o extending useSingleCpuIO option to work with new exch2 I/O format
79      - old-style, missing-tile I/O is still accessible by defining CPP
80        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
81    o monitor package can write to NetCDF files and/or STDOUT
82    o fix re-definition bug in MNC_GRID_INIT_ALL()
83    o doc/api_reference added
84      - a framework for building an API Reference Manual using all
85        the "protex" comments embedded in the code
86      - see pkg/generic_advdiff, pkg/mnc for examples
87    o MNC:
88      - make myThid the last argument for all subroutines
89      - new default for the grid files: NO halos
90      - add useMNC and other run-time flags
91      - separate per-file-group handling of the unlimited dimension
92      - early initialization of MNC w/ flags read at the eeboot stage
93        and lookup tables set in initialize_fixed
94      - write all MNC output to a freshly-created directory
95    o thermodynamics sea-ice (thsice) is now tested with testreport.
96    o test exp. advect_cs: use the standard cs32 grid ; update output.
97    o Added functionality to grdchk:
98      pick global i,j,k position (or nearest wet) where to perform check.
99    
100    checkpoint52l_post
101    o new land formulation:
102      a) use ground enthalpy as prognostic variable to ensure exact
103         energy conservation.
104      b) account for water temperature and for latent heat of freezing
105         in all processes (rain, run-off, ground storage)
106      c) compute surface and ground temperature implicitly.
107    o aim_v23 modification for new land model:
108      a) Treat separately land / ocean / sea-ice surface fluxes
109         to allow implicit computation of land & sea-ice surface temp.
110      b) add snow precipitation.
111    checkpoint52l_pre
112    
113    o fix problem (when 1 tile is empty) in min/max monitor.
114    o fix bug in timeAve (u,vZetatave in common block)
115    o no restoring terms under ice for pkg/seaice
116    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
117    o bug fix for pkg/seaice pickups
118    o change MNC call locations and add coordinate attributes
119    o mask vorticity at the corner ; affects global_ocean.cs output
120    o fix ini_curvilinear_grid ; test CS experiments with mpi
121    o aim.5l_cs: modify sea-ice fraction input file ; update output
122    o exf: Adding simple range check routine for exf fields after read
123    
124    checkpoint52k_post
125    o removed top-level directory "diags"
126      - we migrated these functions to pkg/timeave a long time ago
127    o fixed bug introduced in pkg/monitor
128    o accuracy ctrlprec = 32 insuffient for gradient checks using
129      averaged fields (I/O via cost_averages)
130      -> use ctrl.h in active_file*.F to control I/O precision.
131    o paramter list of CALL ADTHE_MAIN_LOOP
132    o added initial do_the_model_io to ecco
133    o set all ...Freq to zero after cost_final
134      taveFreq, dumpFreq, pChkptFreq
135    o MAIN and ECCO differentiability restored
136    
137    checkpoint52j_post
138    o fix nchklev in tamc.h for global_ocean...
139    o Bringing flow and store directives up-to-date
140    o Really weird thing!
141      call do_the_model_io from the_main_loop with parameters
142      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
143      TAF places a faulty re-call of initialise_varia
144      after cost_final call which should not be there!
145    checkpoint52j_pre
146    
147    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
148      error messages
149    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
150    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
151      debug output
152    o modfied mdsio_writefield.F to handle non-global files under exch2
153    o update AIM Cubed-Sphere exp (aim.5l_cs):
154      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
155    o update AIM Equatorial Channel exp:
156      use standard aim_v23 pkg and change the SST fields to be more realistic.
157    o globalFile now works with exch2
158    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
159      mon_vort3.F to make exch2 friendly with >1 tile per cube face
160    o limit timeave output for hi-res integrations
161    
162    checkpoint52i_post
163    o removed CPP_EEOPTIONS.h from verification/*/code
164    o updated the tiling for global_ocean_pressure
165    checkpoint52i_pre
166    
167    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
168      the old pkg/aim).
169    
170    checkpoint52h_pre
171    o shortened offending lines in exch2_send_rx?.template
172    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
173    o genmake2: add build & execute test for NetCDF code
174    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
175      old grid files, moved CPP_EEMACROS.h to pkg/exch2
176    o added useSingleCPUIO flag to monitor.F and mon_out.F
177    o added temporary hack for sea-ice dynamics on the cube:
178      metric terms are ignored and it is assumed that
179      there is no sea-ice on cube faces 1, 2, 4, and 5.
180    
181    checkpoint52f_post
182    o added exch2 cube routines to pkg/exch2
183    o modified hs94.cs-32x32x5 to use it
184    o added new grid files to hs94.cs-32x32x5
185    checkpoint52f_pre
186    
187    checkpoint52e_post
188    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
189      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
190    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
191      to work with implicit vertical advection and AB ;
192    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
193    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
194     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
195    checkpoint52e_pre
196    
197    o fix bug in impldiff when Nr=1 or Nr=2.
198    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
199    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
200    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
201      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
202    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
203    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
204    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
205    
206    checkpoint52d_post
207    o re-tiled many expts to allow comparison in multi-processor mode
208      - updated output accordingly
209      - changed hs94.128x64x5 to use intial T from file rather than use the
210        random number generator
211    o add infrastructure in model routines for fizhi and gridalt packages
212    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
213    o changes to permit hi-res, cubed-sphere, configuration
214      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
215      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
216      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
217        of surface winds for the cube
218      (A verification experiment, based on global_ocean.cs32x15, but with
219       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
220       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
221       complete with example surface forcing files and matlab scripts to look
222       at the output and compare it with that of global_ocean.cs32x15.)
223    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
224       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
225       to conform to the common rule.
226    o check-in the first version of the coupler + interfaces for multi-components
227       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
228       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
229       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
230       - ocean and atmos. share the same horizontal grid (no interpolation).
231       - exchanges between component and coupler is done in forward_step
232    o new verification experiment, cpl_aim+ocn:
233       coupled ocean - AIM atmosphere on cs32 grid.
234    
235    checkpoint52d_pre
236    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
237    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
238    
239    checkpoint52c_post
240    o Fixing OPTIONS files for use of exf:
241      - ALLOW_ECCO not needed
242      - ECCO_CPPOPTIONS.h should not be included from
243        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
244        as has been the case in the past
245      - All cal/exf related options are currently set in
246        single header file. Should remain so until we
247        agree on a consistent new policy.
248    o Removed all CPP options for cal package.
249      cal has no more CPP options.
250    o modified STOREs in GAD_ADVECTION
251    o corrected key comp. for passkey
252    
253    checkpoint52b_post
254    o new version: "thsice" of thermodynamic sea-ice pkg:
255     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
256     - modify fluxes but do not change theta directly;
257     - light cleaning of bulk_force pkg (still needed with thsice).
258     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
259       + output_thsice.txt to test thsice & bulk_force pkgs.
260    o put back grid & coriolis monitor output.
261    checkpoint52b_pre
262    
263    o call "do_the_model_io" at the beginning (=> dump initial state)
264    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
265    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
266      (need info on NUMBER_OF_PTRACERS)
267    o missing PTRACERS headers in some routines
268    o default tamc.h in pkg/autodiff supposed to crash
269      to ensure proper customization
270    
271    checkpoint52a_post
272    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
273      - moved surfaceTendencyTice from pkg/seaice to main code
274      - subroutine FREEZE_SURFACE now limits only surface temperature
275        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
276        => new output.txt for global_ocean.cs32x15 & global_with_exf
277      - keep the old version of FREEZE for backward compatibility;
278        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
279      - corresponding modifs for TAF directives
280    o added surface flux output variables to TIMEAVE_STATVARS
281    o time-averaged output for pkg/ptracers
282    o fix problem with ECCO-related divided adjoint
283      snapshot file was missing some ad-variables,
284      but no warning issued by TAF
285    
286    checkpoint52a_pre
287    o some bug fixes for #undef REAL4_IS_SLOW
288    
289    checkpoint52 = ecco_c52_e35
290    o after testing adjoints of checkpoint51u_post
291    
292    checkpoint51u_post
293    o this is the post-merge tag of the ecco-branch
294      (needs another clean checkout and re-testing)
295    o various natl_box_adjoint configs and results
296      but no input fields
297    o obcs adjoint not yet merged!
298    o adding ECCO global 1x1 and 2x2 degree configs
299    o updated/extended some store directives for seaice
300    o pkg/ecco now containes ecco-specific part of cost function
301    o top level routines the_main_loop, forward_step
302      supersede those in model/src/
303      previous input data.cost now in data.ecco
304      (new namelist ecco_cost_nml)
305    o in ctrl/ cleaned some cross-dependencies and updated CPP options
306    
307    checkpoint51t_post
308    o this is the pre-merge tag of the ecco-branch
309    
310    checkpoint51s_post
311    o cleanup: removed various obsolete #define-s
312    o pkg/grdchk
313      - renamed 'ph-grd 3' to 'grad-res'
314      - merged from ecco-branch
315        (remaining bug fixes for obcs gradient checks)
316      - additional high-precision output for testreport
317        (grep for 'precision_grdchk_result')
318    
319    checkpoint51r_post
320    o cleaned up or removed CPP_OPTIONS.h files
321    o updated results for some of the tests to reflect the new
322      optfiles (-ieee: -O0 instead of -O3)
323    
324    checkpoint51q_post
325    o cd_code:
326      - moved cd_scheme.F -> cd_code_scheme.F
327      - separate read_checkpoint from cd_code_ini_vars.F
328      - separated cd_code part from write_checkpoint
329      - updated AD_SOURCE, generated .flow
330      - added CD_CODE_VARS.h to the_main_loop
331      - Moving cd_code specific store dir.s to pkg/cd_code
332    o ctrl package totally restructured
333      - pack/unpack now optional and decoupled from
334        xx_/adxx_ I/O
335      - ctrl_pack/unpack cleaned
336        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
337      - confined inclusion of AD_CONFIG.h to where necessary.
338    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
339    
340    checkpoint51p_post
341    o create initial cd_code package
342      - WARNING: the initialization of fields within packages
343        is broken because INI_FIELDS (where READ_CHECKPOINT is
344        called) is called *before* PACKAGES_INIT_VARIABLES.
345        This seems to be backwards since
346        1) its important to initially zero the entire field including
347           the "halo" region
348        2) zeroing needs to be done *before* reading pickup info
349           and the pickup call might or might not happen in any
350           particular run
351      - this needs an overhaul for R2
352    o cleanup verification/*/code/GMREDI_OPTIONS.h
353    o cleanup testreport
354    
355    checkpoint51o_post
356    o bringing AD-related verif's up to date with genmake2
357      - carbon/
358      - global_ocean.90x40x15/
359      - hs.94.1x64x5/
360      - (front_relax/ )
361    o (more) consistent directory structure for AD-related verif.'s
362    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
363    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
364    o bug fix in find_alpha.F for MDJWF:
365      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
366        change rho -> rho-rhoConst
367      - replace call find_rho to find_rhonum
368    o initialisation of rFlx extended to full array (required by TAF)
369      and shifted to thermodynamics
370    o removed PTRACERS.h in ptracers routine
371    o added surfacetendencyPtr to S/R parameter list pracers_forcing
372    o Correcting initialisations for fVerU, fVerV.
373    o helping TAF to recognize dependency on kUp for
374      fVerU, fVerV
375    o Replacing delZ by delR in pkg/ctrl/
376    checkpoint51o_pre
377    
378    o undid all of cp51 pending some cleanups and discussion
379    o added the [#include "AD_CONFIG.h"] statement to all files that need
380       it for adjoint/tl #defines
381     o re-worked the build logic in genmake2 to support AD_CONFIG.h
382     o removed tools/genmake since it no longer works
383    
384    checkpoint51n_post
385    o modifications to make FREEZE flux visible to pkg/kpp
386      - moved surfaceTendencyTice from pkg/seaice to main code
387      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
388      - subroutine FREEZE now limits only surface temperature
389        (this means new output.txt for global_ocean.90x40x15,
390         global_ocean.cs32x15, and global_with_exf)
391    o added surface flux output variables to TIMEAVE_STATVARS
392    
393    checkpoint51n_pre
394    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
395    o added [#include "AD_CONFIG.h"] to all files that use the following
396      defines:
397      - ALLOW_ADJOINT_RUN
398      - ALLOW_TANGENTLINEAR_RUN
399      - ALLOW_ECCO_OPTIMIZATION
400    
401    checkpoint51m_post
402    o incorporating changes to get TAMC/TAF working in genmake2
403      - added new TAMC/TAF targets to the Makefile
404      - various cleanups related to package handling
405      - these changes should have no impact on the forward model
406    
407    checkpoint51l_post
408    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
409     - faster algorithm for cal_addtime.F

428    o set gravitySign automatically according to the vertical coordinate used
429      (and change sign: back to "logical" value: +1 when R increases downward)
430    o added an include barrier to the default CPP_OPTIONS.h and
431      removed the #include "PACKAGES_CONFIG.h" from it
432    o fix a bug in mom_fluxform (from chk51j_post)
433    
434    checkpoint51j_post
435    o Added some AD-related initialisations in mom_vecinv/ mom_fluxform/
436    o adjusted some flow directives (dynamics, thermodynamics)
437    o added cubed-sphere case to test cost function
438    o heckpoint_lev?_directives.h now include
439      pkg-specific directives, whenever those are enabled.
440    o Moving pkg-specific flow directives to corresponding pkg
441      Moving pkg-specific differentiation list to corresponding pkg
442      Moving pkg-specific checkpoint-lev storing to corresponding pkg
443      ---> conventions are
444           - pkg_ad.flow
