3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  checkpoint53d_post
7    o faulks upgraded: re-generate output.txt that have changed:
8       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
9    o Added Bryan and Lewis, 1979, vertical diffusivity profile
10    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
11    o added Sadourny discretization of Coriolis
12      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
13      - re-enabled use of omega3 (useAbsVorticity)
14    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
15      vector-invariant equations
16      - note: does *NOT* yet use same variable visc. for no-slip BC's.
17    o recoded the lateral boundary conditions for non-hydrostatic w, this time
18      hopefully without new bugs
19      - still to do: biharmonic friction for non-hydrostatic w
20    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
21    o regenerated output for global_ocean_ebm (using -ieee)
22    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
23      of mom_common/
24      - simple re-arrangement of instructions within computing loop
25    checkpoint53d_pre
26    
27    checkpoint53c_post
28    o new version of coupler for AIM+thSIce and Ocean models
29     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
30     - land: change Evaporation of snow
31     - aim with thSIce: fix bug in snow-precip.
32    o changes to calc_gw.F
33     - bug fix for w^2 term near the bottom boundary
34     - (hopefully) improve the lateral slip boundary condtions for use with
35        partial/looped cells
36      - because the bug fix changes two verification experiments anyway (exp5
37        and plume on slope), change the lateral boundary condition from half slip
38        to the value of no_slip_sides
39    o ebm package wasnt quite up to the parallel task. Fixed that.
40    o Adjoint of EBM package + verification
41      * TLM OK
42      * ADM not sufficient accuracy yet (needs further testing)
43    
44    checkpoint53b_post
45    o Commiting new energy balance model to repository
46      * package is pkg/ebm
47      * verif. is verification/global_ocean_ebm
48      * references are in ebm_driver.F
49    C      * X. Wang, P. Stone and J. Marotzke, 1999:
50    C        Global thermohaline circulation. Part I:
51    C        Sensitivity to atmospheric moisture transport.
52    C        J. Climate 12(1), 71-82
53    C      * X. Wang, P. Stone and J. Marotzke, 1999:
54    C        Global thermohaline circulation. Part II:
55    C        Sensitivity with interactive transport.
56    C        J. Climate 12(1), 83-91
57    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
58    C        Destabilization of the thermohaline circulation
59    C        by atmospheric eddy transports.
60    C        J. Climate 7(12), 1870-1882
61    o Will need long integration testing.
62    checkpoint53b_pre
63    
64    o created pkg/mom_common in preparation for variable viscosity code
65    o renamed and split ini_mnc_io
66    o pkg/land: only liquid water can diffuse or run-off
67    o AIM using land: soil wetness availability account for snow
68    o added printMapIncludesZeros to EEPARMS namelist
69    
70    checkpoint53a_post
71    o restore TAMC compatiility for exf_constants.h
72      (no usage of _d in .h)
73    o Additional storing in KPP in an attempt to fix
74      TAMC problem with adjoint of KPP code.
75      (no success...)
76      Identical code works fine with TAF.
77    o Fixed verification/natl_box_adjoint experiments.
78      Initial conditions for Experiments 4 and 5 are now
79      set to "SEAICE_initialHEFF=0", which is more reasonable,
80      and hence gives results closer to that of Experiment 2.
81      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
82    
83    checkpoint53
84    o stable checkpoint with up to date adjoint
85      TLM tests only run for 1st grdchk at the moment. Its unclear if
86      this is a code problem or a problem with resetting code for g_
87      variables that is being autogenerated wrong.
88      Otherwise:
89       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
90       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
91         are both still in chaos following their security messes.
92    
93    checkpoint52n_post
94    o various build (mostly genmake2) changes including:
95      - ability to build/run more easily within Cygwin and MacOS X
96      - more complicated Makefiles with a stronger dependence on Gnu Make
97    o pkg/seaice modifications
98      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
99        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
100        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
101      - changed proxy for geostrophic velocity and updated
102        verification/lab_sea/results/* accordingly
103      - removed ADI dynamic solver from pkg/seaice
104      - replaced all occurrences of 1/CSTICE or 1/CSUICE
105        they caused a segmentation fault under certain circumstances
106      - removed unused field WATR
107    o bug fix in exf-package:
108      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
109         now reflect that.
110    o small fixes in the cal-package:
111      - set reference date to first of January for the 'model'-calendar
112      - failing of cal_CheckDate in cal_FullDate now actually results in a
113        warning
114    o small modifications in exf-package to increase flexibility:
115      - change climtempfreeze from a constant to a runtime parameter that
116        is specified in data.exf_clim (default = -1.9)
117      - introduce runtime parameter windstressmax (default = 2.0) that is
118        specified in data.exf
119    o fix in pkg/thsice:
120      - update Evap (Tsf changes) to be consistent with Latent heat flux
121      - maintain snow precipitation unchanged (even if Tsf >=0).
122     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
123    
124    checkpoint52m_post
125    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
126      this does not change any of the results, because myIter=0 in swfrac always
127      lead to jwtype=2 (the default anyway), but the call makes little sense
128      as a default
129    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
130    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
131      atmospheric model (AIM) to use it ; add a "slab ocean" component.
132    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
133    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
134    o extending useSingleCpuIO option to work with new exch2 I/O format
135      - old-style, missing-tile I/O is still accessible by defining CPP
136        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
137    o monitor package can write to NetCDF files and/or STDOUT
138    o fix re-definition bug in MNC_GRID_INIT_ALL()
139    o doc/api_reference added
140      - a framework for building an API Reference Manual using all
141        the "protex" comments embedded in the code
142      - see pkg/generic_advdiff, pkg/mnc for examples
143    o MNC:
144      - make myThid the last argument for all subroutines
145      - new default for the grid files: NO halos
146      - add useMNC and other run-time flags
147      - separate per-file-group handling of the unlimited dimension
148      - early initialization of MNC w/ flags read at the eeboot stage
149        and lookup tables set in initialize_fixed
150      - write all MNC output to a freshly-created directory
151    o thermodynamics sea-ice (thsice) is now tested with testreport.
152    o test exp. advect_cs: use the standard cs32 grid ; update output.
153    o Added functionality to grdchk:
154      pick global i,j,k position (or nearest wet) where to perform check.
155    
156    checkpoint52l_post
157    o new land formulation:
158      a) use ground enthalpy as prognostic variable to ensure exact
159         energy conservation.
160      b) account for water temperature and for latent heat of freezing
161         in all processes (rain, run-off, ground storage)
162      c) compute surface and ground temperature implicitly.
163    o aim_v23 modification for new land model:
164      a) Treat separately land / ocean / sea-ice surface fluxes
165         to allow implicit computation of land & sea-ice surface temp.
166      b) add snow precipitation.
167    checkpoint52l_pre
168    
169    o fix problem (when 1 tile is empty) in min/max monitor.
170    o fix bug in timeAve (u,vZetatave in common block)
171    o no restoring terms under ice for pkg/seaice
172    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
173    o bug fix for pkg/seaice pickups
174    o change MNC call locations and add coordinate attributes
175    o mask vorticity at the corner ; affects global_ocean.cs output
176    o fix ini_curvilinear_grid ; test CS experiments with mpi
177    o aim.5l_cs: modify sea-ice fraction input file ; update output
178    o exf: Adding simple range check routine for exf fields after read
179    
180    checkpoint52k_post
181    o removed top-level directory "diags"
182      - we migrated these functions to pkg/timeave a long time ago
183    o fixed bug introduced in pkg/monitor
184    o accuracy ctrlprec = 32 insuffient for gradient checks using
185      averaged fields (I/O via cost_averages)
186      -> use ctrl.h in active_file*.F to control I/O precision.
187    o paramter list of CALL ADTHE_MAIN_LOOP
188    o added initial do_the_model_io to ecco
189    o set all ...Freq to zero after cost_final
190      taveFreq, dumpFreq, pChkptFreq
191    o MAIN and ECCO differentiability restored
192    
193    checkpoint52j_post
194    o fix nchklev in tamc.h for global_ocean...
195    o Bringing flow and store directives up-to-date
196    o Really weird thing!
197      call do_the_model_io from the_main_loop with parameters
198      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
199      TAF places a faulty re-call of initialise_varia
200      after cost_final call which should not be there!
201    checkpoint52j_pre
202    
203    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
204      error messages
205    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
206    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
207      debug output
208    o modfied mdsio_writefield.F to handle non-global files under exch2
209    o update AIM Cubed-Sphere exp (aim.5l_cs):
210      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
211    o update AIM Equatorial Channel exp:
212      use standard aim_v23 pkg and change the SST fields to be more realistic.
213    o globalFile now works with exch2
214    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
215      mon_vort3.F to make exch2 friendly with >1 tile per cube face
216    o limit timeave output for hi-res integrations
217    
218    checkpoint52i_post
219    o removed CPP_EEOPTIONS.h from verification/*/code
220    o updated the tiling for global_ocean_pressure
221    checkpoint52i_pre
222    
223    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
224      the old pkg/aim).
225    
226    checkpoint52h_pre
227    o shortened offending lines in exch2_send_rx?.template
228    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
229    o genmake2: add build & execute test for NetCDF code
230    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
231      old grid files, moved CPP_EEMACROS.h to pkg/exch2
232    o added useSingleCPUIO flag to monitor.F and mon_out.F
233    o added temporary hack for sea-ice dynamics on the cube:
234      metric terms are ignored and it is assumed that
235      there is no sea-ice on cube faces 1, 2, 4, and 5.
236    
237    checkpoint52f_post
238    o added exch2 cube routines to pkg/exch2
239    o modified hs94.cs-32x32x5 to use it
240    o added new grid files to hs94.cs-32x32x5
241    checkpoint52f_pre
242    
243    checkpoint52e_post
244    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
245      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
246    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
247      to work with implicit vertical advection and AB ;
248    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
249    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
250     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
251    checkpoint52e_pre
252    
253    o fix bug in impldiff when Nr=1 or Nr=2.
254    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
255    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
256    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
257      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
258    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
259    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
260    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
261    
262    checkpoint52d_post
263    o re-tiled many expts to allow comparison in multi-processor mode
264      - updated output accordingly
265      - changed hs94.128x64x5 to use intial T from file rather than use the
266        random number generator
267    o add infrastructure in model routines for fizhi and gridalt packages
268    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
269    o changes to permit hi-res, cubed-sphere, configuration
270      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
271      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
272      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
273        of surface winds for the cube
274      (A verification experiment, based on global_ocean.cs32x15, but with
275       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
276       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
277       complete with example surface forcing files and matlab scripts to look
278       at the output and compare it with that of global_ocean.cs32x15.)
279    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
280       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
281       to conform to the common rule.
282    o check-in the first version of the coupler + interfaces for multi-components
283       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
284       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
285       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
286       - ocean and atmos. share the same horizontal grid (no interpolation).
287       - exchanges between component and coupler is done in forward_step
288    o new verification experiment, cpl_aim+ocn:
289       coupled ocean - AIM atmosphere on cs32 grid.
290    
291    checkpoint52d_pre
292    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
293    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
294    
295    checkpoint52c_post
296    o Fixing OPTIONS files for use of exf:
297      - ALLOW_ECCO not needed
298      - ECCO_CPPOPTIONS.h should not be included from
299        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
300        as has been the case in the past
301      - All cal/exf related options are currently set in
302        single header file. Should remain so until we
303        agree on a consistent new policy.
304    o Removed all CPP options for cal package.
305      cal has no more CPP options.
306    o modified STOREs in GAD_ADVECTION
307    o corrected key comp. for passkey
308    
309    checkpoint52b_post
310    o new version: "thsice" of thermodynamic sea-ice pkg:
311     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
312     - modify fluxes but do not change theta directly;
313     - light cleaning of bulk_force pkg (still needed with thsice).
314     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
315       + output_thsice.txt to test thsice & bulk_force pkgs.
316    o put back grid & coriolis monitor output.
317    checkpoint52b_pre
318    
319    o call "do_the_model_io" at the beginning (=> dump initial state)
320    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
321    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
322      (need info on NUMBER_OF_PTRACERS)
323    o missing PTRACERS headers in some routines
324    o default tamc.h in pkg/autodiff supposed to crash
325      to ensure proper customization
326    
327    checkpoint52a_post
328    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
329      - moved surfaceTendencyTice from pkg/seaice to main code
330      - subroutine FREEZE_SURFACE now limits only surface temperature
331        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
332        => new output.txt for global_ocean.cs32x15 & global_with_exf
333      - keep the old version of FREEZE for backward compatibility;
334        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
335      - corresponding modifs for TAF directives
336    o added surface flux output variables to TIMEAVE_STATVARS
337    o time-averaged output for pkg/ptracers
338    o fix problem with ECCO-related divided adjoint
339      snapshot file was missing some ad-variables,
340      but no warning issued by TAF
341    
342    checkpoint52a_pre
343    o some bug fixes for #undef REAL4_IS_SLOW
344    
345    checkpoint52 = ecco_c52_e35
346    o after testing adjoints of checkpoint51u_post
347    
348    checkpoint51u_post
349    o this is the post-merge tag of the ecco-branch
350      (needs another clean checkout and re-testing)
351    o various natl_box_adjoint configs and results
352      but no input fields
353    o obcs adjoint not yet merged!
354    o adding ECCO global 1x1 and 2x2 degree configs
355    o updated/extended some store directives for seaice
356    o pkg/ecco now containes ecco-specific part of cost function
357    o top level routines the_main_loop, forward_step
358      supersede those in model/src/
359      previous input data.cost now in data.ecco
360      (new namelist ecco_cost_nml)
361    o in ctrl/ cleaned some cross-dependencies and updated CPP options
362    
363    checkpoint51t_post
364    o this is the pre-merge tag of the ecco-branch
365    
366    checkpoint51s_post
367    o cleanup: removed various obsolete #define-s
368    o pkg/grdchk
369      - renamed 'ph-grd 3' to 'grad-res'
370      - merged from ecco-branch
371        (remaining bug fixes for obcs gradient checks)
372      - additional high-precision output for testreport
373        (grep for 'precision_grdchk_result')
374    
375    checkpoint51r_post
376    o cleaned up or removed CPP_OPTIONS.h files
377    o updated results for some of the tests to reflect the new
378      optfiles (-ieee: -O0 instead of -O3)
379    
380    checkpoint51q_post
381    o cd_code:
382      - moved cd_scheme.F -> cd_code_scheme.F
383      - separate read_checkpoint from cd_code_ini_vars.F
384      - separated cd_code part from write_checkpoint
385      - updated AD_SOURCE, generated .flow
386      - added CD_CODE_VARS.h to the_main_loop
387      - Moving cd_code specific store dir.s to pkg/cd_code
388    o ctrl package totally restructured
389      - pack/unpack now optional and decoupled from
390        xx_/adxx_ I/O
391      - ctrl_pack/unpack cleaned
392        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
393      - confined inclusion of AD_CONFIG.h to where necessary.
394    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
395    
396    checkpoint51p_post
397    o create initial cd_code package
398      - WARNING: the initialization of fields within packages
399        is broken because INI_FIELDS (where READ_CHECKPOINT is
400        called) is called *before* PACKAGES_INIT_VARIABLES.
401        This seems to be backwards since
402        1) its important to initially zero the entire field including
403           the "halo" region
404        2) zeroing needs to be done *before* reading pickup info
405           and the pickup call might or might not happen in any
406           particular run
407      - this needs an overhaul for R2
408    o cleanup verification/*/code/GMREDI_OPTIONS.h
409    o cleanup testreport
410    
411    checkpoint51o_post
412    o bringing AD-related verif's up to date with genmake2
413      - carbon/
414      - global_ocean.90x40x15/
415      - hs.94.1x64x5/
416      - (front_relax/ )
417    o (more) consistent directory structure for AD-related verif.'s
418    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
419    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
420    o bug fix in find_alpha.F for MDJWF:
421      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
422        change rho -> rho-rhoConst
423      - replace call find_rho to find_rhonum
424    o initialisation of rFlx extended to full array (required by TAF)
425      and shifted to thermodynamics
426    o removed PTRACERS.h in ptracers routine
427    o added surfacetendencyPtr to S/R parameter list pracers_forcing
428    o Correcting initialisations for fVerU, fVerV.
429    o helping TAF to recognize dependency on kUp for
430      fVerU, fVerV
431    o Replacing delZ by delR in pkg/ctrl/
432    checkpoint51o_pre
433    
434    o undid all of cp51 pending some cleanups and discussion
435    o added the [#include "AD_CONFIG.h"] statement to all files that need
436       it for adjoint/tl #defines
437     o re-worked the build logic in genmake2 to support AD_CONFIG.h
438     o removed tools/genmake since it no longer works
439    
440    checkpoint51n_post
441    o modifications to make FREEZE flux visible to pkg/kpp
442      - moved surfaceTendencyTice from pkg/seaice to main code
443      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
444      - subroutine FREEZE now limits only surface temperature
445        (this means new output.txt for global_ocean.90x40x15,
446         global_ocean.cs32x15, and global_with_exf)
447    o added surface flux output variables to TIMEAVE_STATVARS
448    
449    checkpoint51n_pre
450  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
451  o added [#include "AD_CONFIG.h"] to all files that use the following  o added [#include "AD_CONFIG.h"] to all files that use the following
