4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
8    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
9        not used right now, but can be used in BGC packages to fix conservation.
10    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
11        other packages too.
12    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
13       SEAICE_rhoIce in the Rothrock (1975)-type strength calculations
14       (bug fix)
15    o model/src:
16      - since we have several heat capacity (even in model/src), define "recip_Cp"
17        as local variable (no longer in common block) to avoid any confusion.
18      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
19    o pkg/exf:
20      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
21        air density as function of air Temp, Humidity and atm pressure.
22    
23    checkpoint64w (2014/05/02)
24    o verification:
25      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
26        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
27        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
28        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
29        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
30    o model/src: for atmosphere in p* coords:
31      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
32      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
33        but not yet activated.
34    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
35      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
36      - this changes the results (but not for any verification experiment, because
37        none tests this), but avoids having an extra field in the restart files
38    o pkg/seaice: remove global variable TICE (not needed)
39      - replace by TICES or local variable where necessary (cost_seaice_test,
40        seaice_diagnostics_state)
41      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
42      - use specific read/write routines for reading and writing individual leves
43        of a multilevel field
44    o pkg/ctrl & model/inc:
45      - move additional anomaly fields of control vars (related to options:
46         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
47        from DYNVARS.h into new header file: CTRL_FIELDS.h
48    o pkg/seaice: some small modifications to the ridging code
49      - make fw2ObyRidge a global variable and add the freshwater flux to
50        seaice_growth
51      - pass actual thickness from seaice_prepare_ridging, so that it is
52        computed only in one place and compute it in the same way as in
53        seaice_growth
54      - initialise more fields in seaice_do_ridging that where cause floating
55        point exceptions over land
56    o pkg/seaice: preparations for ridging code and first real ridging code
57      - move most of "PART 1" of S/R seaice_growth into a new and separate
58        S/R seaice_reg_ridge that will both regularize the state variable after
59        advection call the actual ridging routine;
60      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
61        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
62      - remove ridging code from seaice_advdiff
63      - clean up remaining part 1 of seaice_growth in an attempt to make it
64        more readable (this is probably subjective)
65      - call seaice_itd_redist once in the initialisation phase to have the initial
66        conditions in the correct category
67      - finally: add new ridging routine for ITD code
68    
69    checkpoint64v (2014/04/11)
70    o pkg/ecco:
71      - add runtime parameters mdt[start,end]date[1,2]
72      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
73    o pkg/seaice:
74      - make deltaC a global variable, so that it can be used in ridging code
75      - first step towards ridging: introduce new routines that compute
76        ice strength based on ridging parameters
77      - add diagnostic for HSNOWITD
78      - add opnWtrFrac as a global variable (required for ridging scheme)
79    o pkg/salt_plume + pkg/seaice/seaice_growth.F
80      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
81        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
82    o verification/hs94.1x64x5:
83      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
84      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
85    o autodiff:
86      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
87        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
88        For now, only in pkgs used in verification/hs94.1x64x5.
89      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
90        which are specific to TAF/TAMC).
91      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
92        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
93        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
94      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
95        building mitgcmuv_ad (make adAll).
96    o pkg/ecco:
97      - cost_gencost_seaicev4.F:
98         reformulate proxy cost as function of sst and local param SEAICE_freeze
99         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
100      - add stop statement if old names siv4-[sst,vol] are used
101      - add snapshots + cost reports for atmospheric longwave
102      - remove factor 0.1 in front of wtau[u,v]
103      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
104         ALLOW_TMI_SST_COST_CONTRIBUTION
105    o pkg/atm_phys:
106      - add some diagnostics for Short-wave and for convection S/R.
107    o pkg/seaice/seaice_growth:
108      - fix a bug in the lateral melt parameterization for SEAICE_ITD
109        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
110      - rearrange loop order for better vector code in the same code block
111      - rewrite the floeDiameter formula to have fewer divisions
112      -  (miraculously) none of this changes the results of seaice_itd
113    o pkg/smooth:
114      - move param smooth2Ddiffnbt to pkg/ecco
115    o pkg/salt_plume:
116      - salt_plume_frac.F:
117         clean up local param names
118         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
119    o pkg/rw:
120      - add RS version of S/R READ_MFLDS_LEV.
121    o pkg/streamice:
122      - fix the restart test by writing/reading pickup_streamice files.
123    o pkg/seaice:
124      - refine checks for jfnk-related parameters
125      - comment out if statement with SEAICEuseIMEX parameter as long as there
126        is no IMEX code to avoid confusion and surprises
127    
128    checkpoint64u (2014/03/07)
129    o verification/MLAdjust:
130      - rename secondary test suffix:
131         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
132         0.leithD -> AhFlxF  + switch to flux-form
133         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
134         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
135    o pkg/mom_vecinv:
136      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
137        to be before mom_calc_visc.F)
138      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
139      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
140        this is simpler for the adjoint and for diagnostics.
141    o model/src + pkg/momentum:
142      - add input files for  2-D additional Western and Southern cell-edge wall
143         (e.g., to add "thin-wall" where it is =1).
144      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
145        using 2nd hFacZ that is computed from initial (fix domain) hFac
146      - known limitations of thin wall implementation: not yet coded for sigma
147        coords; not working with CD-scheme neither.
148    o pkg/seaice:
149      - rename recently introduced parameters from (wrong name) AB to
150        BDF (backward difference time discretisation)
151      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
152    o tools/adjoint_options:
153      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
154    
155    checkpoint64t (2014/02/01)
156    o pkg/ecco
157      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
158        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
159      - replace hard-coded record number and period which only work for monthly
160        with read-in runtime param that works for other periods (month,day,year)
161    o pkg/thsice
162      - corrected store directive fixes thsice adjoint gradient checks
163    o genmake2 & testreport:
164      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
165        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
166        Update testreport accordingly. No need to set "export OPENAD=true"
167        in adjoint_options/adjoint_oad anymore (will be removed later).
168    o pkg/shelfice:
169      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
170        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
171        so that surface forcing applies to k=kSurf if using pkg/shelfice.
172    o pkg/ctrl, pkg/grdchk, pkg/ecco:
173      - Changes to make GENARR more modular (i.e. invisible if not used)
174    o model/src/temp_integrate.F and salt_integrate.F
175      - re-include store directives that were removed on Dec 27th.
176    o model/src/external_forcing_surf.F
177      - add storage directives for EmPmR and PmEpR to avoid recomputation of
178        seaice_model in the adjoint that is problematic when seaice_model is
179        turned off in the adjoint. The resolved issue dated back to July when
180        EXTERNAL_FORCING_SURF call was moved.
181        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
182    o pkg/exf/exf_check.F
183      - fix a small bug again (originally found by Wentao Liu, now found again)
184      - streamline error output
185    o pkg/streamice and aim_v23:
186      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
187        Apple's /usr/bin/cpp knows what to do:
188        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
189        Target: x86_64-apple-darwin13.0.0
190    
191    checkpoint64s (2014/01/05)
192    o tools/adjoint_options:
193      - switch to fastopt.net TAF server (instead of default fastopt.de) for
194        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
195    o model/src:
196      - remove some unnecessary TAF storage directives in forward_step.F and
197        in dynamics.F (note: not always removed by TAF, e.g., double storage
198        of kappaRU,kappaRV in former version of dynamics.F).
199    o model/src & pkg/ptracers:
200      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
201        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
202        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
203      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
204      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
205      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
206    o useSingleCpuInput separates single-CPU input from single-CPU output;
207        for now only implemented for in exf_interp_read.F
208    o verification/advect_xy:
209      - fix missing EXCH call in local version of ini_salt.F and update output.
210    o momentum diagnostics:
211      - fix which deltaT is used in Total-Tendency diagnostics.
212      - fix typo in diagnostics for momentum tendency from AB.
213    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
214        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
215    
216    checkpoint64r (2013/12/08)
217    o verification/*/results:
218      - Update reference output of experiments that were passing with just 13 digits
219         (make it easier to detect future changes in results)
220    o model/src & pkg/ptracers:
221      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
222        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
223        to inside ptracers_integrate.F ; remove ptracers_advection.F
224    o coupling interface pkgs:
225        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
226      - change the config check to test the agreement of Ocean Depth
227        with ATM land/sea mask (instead of ATM orography);
228      - send to coupler the number of coupler time-steps to do for this run:
229        this allows to check for consistency and don't need anymore to be
230        specified in parameter file "data";
231      in coupler:
232      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
233      - improve report to log-file of config setting (pass log-file unit to few S/R)
234    o pkg/compon_communic:
235      - add coupling send/receive for non-tiled integer vector;
236      - add S/R to check and stop if any proc has an error (similar to
237        eesupp/src/stop_if_error.F but single thread and across Comm_World).
238    o pkg/exch2:
239      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
240        through list of all tiles my proc owns.
241    o model/src:
242      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
243        from rTrans) to simplify dependencies (no need to store rTrans anymore in
244        calling S/R); this affects AD results at machine truncation level:
245        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
246        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
247    o tools/build_options:
248      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
249    o coupling interface pkgs:
250        [compon_communic, atm_compon_interf & ocn_compon_interf]
251      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
252        to each S/R that needs it; remove un-used variables.
253      - change component tile registration (cpl_register.F in both compon_interf
254        and mitcomponent_tile_register.F) to pass the full list of tiles
255        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
256      - with pkg/exch2: adopt the same convention used for I/O to define mapping
257        towards coupler global array (unless W2_useE2ioLayOut=F):
258         a) can now use different tiling between atm & ocn comp.
259         b) no needs to modify the run-Off map when changing tiling (was needed
260            even if using the same tiling between atm & ocn).
261         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
262            full land tiles); not yet tested.
263      - check for valid mapping from comp. tile to coupler global array
264      - improve report of tile registration results to log file.
265    o pkg/exch2:
266      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
267        tile-registration (CPL_REGISTER);
268      - activate (un-comment) definition and setting of "W2_tileIndex" list to
269        store the local bi,bj indices of each tile;
270      - also print bi,bj in local report to log file;
271      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
272        Jun 2009 modif of pkg/exch2).
273    o testing on baudelaire:
274      - run 2 tests at a time: no significant slow down (since enough cpu) and
275        get the full set of test done earlier
276      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
277    o model/src/thermodynamics.F and routines called from it:
278      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
279        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
280        velocity (outp) by adding bolus velocity.
281      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
282        mass transport from velocity + lateral grid cell area
283      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
284      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
285     in thermodynamics.F
286      - remove k from thermodynamics.F and move it to temp_integrate.F
287        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
288        loop).
289      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
290        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
291        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
292        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
293      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
294        global_ocean.90x40x15, tutorial_global_oce_biogeo and
295        tutorial_tracer_adjsens (+ TLM output).
296    o tools/OAD_support and (verification/*/) code_oad:
297      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
298        module conversion ; remove unneeded CPP_EEOPTIONS.h.
299      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
300        version (closer to model/inc/CPP_OPTIONS.h).
301    o model/src:
302      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
303        retired list of parameters (routine FREEZE has been replace by surface
304        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
305    o pkg/gmredi:
306      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
307        velocity (same scheme but affects machine truncation) for GM_AdvForm.
308      - update output of FWD experiments: front_relax.bvp,
309        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
310    
311    checkpoint64q (2013/11/17)
312    o verification:
313      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
314        tutorial_global_oce_biogeo and global_ocean.90x40x15.
315      - generate new output (growth & melt) for seaice_itd experiment after
316        updating the input pickup_seaice files (previously wrong).
317    o pkg/cost:
318      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
319        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
320        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
321          cannot be applied to var in common block).
322        o allows to get results independent of tile-per-proc setting (if using
323          slower GLOBAL_SUM_SEND_RECV option).
324      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
325        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
326        forward gradients: update output).
327      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
328        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
329    o pkg/mom_common:
330      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
331        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
332        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
333        ensure that all field value that are used are set.
334    o tutorial_deep_convection (smag3d):
335      - add missing scaling in mom_calc_smag_3d.F;
336      - set smag3D_coeff in input.smag3d such that results do not change.
337    o pkg/dic:
338      - change dic_cost.F to compute cost on each tile first and then apply
339        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
340        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
