4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
8       SEAICE_rhoIce in the Rothrock (1975)-type strength calculations
9       (bug fix)
10    
11    o model/src:
12      - since we have several heat capacity (even in model/src), define "recip_Cp"
13        as local variable (no longer in common block) to avoid any confusion.
14      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
15    o pkg/exf:
16      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
17        air density as function of air Temp, Humidity and atm pressure.
18    
19    checkpoint64w (2014/05/02)
20    o verification:
21      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
22        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
23        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
24        affects AD gradient (down to 8-7 matching digits for global_ocean and
25        5-6 for lab_sea).
26    seaice_reg_ridge.F seaice_do_ridging.F
27    o model/src: for atmosphere in p* coords:
28      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
29      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
30        but not yet activated.
31    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
32      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
33      - this changes the results (but not for any verification experiment, because
34        none tests this), but avoids having an extra field in the restart files
35    o pkg/seaice: remove global variable TICE (not needed)
36      - replace by TICES or local variable where necessary (cost_seaice_test,
37        seaice_diagnostics_state)
38      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
39      - use specific read/write routines for reading and writing individual leves
40        of a multilevel field
41    o pkg/ctrl & model/inc:
42      - move additional anomaly fields of control vars (related to options:
43         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
44        from DYNVARS.h into new header file: CTRL_FIELDS.h
45    o pkg/seaice: some small modifications to the ridging code
46      - make fw2ObyRidge a global variable and add the freshwater flux to
47        seaice_growth
48      - pass actual thickness from seaice_prepare_ridging, so that it is
49        computed only in one place and compute it in the same way as in
50        seaice_growth
51      - initialise more fields in seaice_do_ridging that where cause floating
52        point exceptions over land
53    o pkg/seaice: preparations for ridging code and first real ridging code
54      - move most of "PART 1" of S/R seaice_growth into a new and separate
55        S/R seaice_reg_ridge that will both regularize the state variable after
56        advection call the actual ridging routine;
57      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
58        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
59      - remove ridging code from seaice_advdiff
60      - clean up remaining part 1 of seaice_growth in an attempt to make it
61        more readable (this is probably subjective)
62      - call seaice_itd_redist once in the initialisation phase to have the initial
63        conditions in the correct category
64      - finally: add new ridging routine for ITD code
65    
66    checkpoint64v (2014/04/11)
67    o pkg/ecco:
68      - add runtime parameters mdt[start,end]date[1,2]
69      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
70    o pkg/seaice:
71      - make deltaC a global variable, so that it can be used in ridging code
72      - first step towards ridging: introduce new routines that compute
73        ice strength based on ridging parameters
74      - add diagnostic for HSNOWITD
75      - add opnWtrFrac as a global variable (required for ridging scheme)
76    o pkg/salt_plume + pkg/seaice/seaice_growth.F
77      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
78        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
79    o verification/hs94.1x64x5:
80      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
81      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
82    o autodiff:
83      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
84        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
85        For now, only in pkgs used in verification/hs94.1x64x5.
86      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
87        which are specific to TAF/TAMC).
88      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
89        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
90        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
91      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
92        building mitgcmuv_ad (make adAll).
93    o pkg/ecco:
94      - cost_gencost_seaicev4.F:
95         reformulate proxy cost as function of sst and local param SEAICE_freeze
96         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
97      - add stop statement if old names siv4-[sst,vol] are used
98      - add snapshots + cost reports for atmospheric longwave
99      - remove factor 0.1 in front of wtau[u,v]
100      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
101         ALLOW_TMI_SST_COST_CONTRIBUTION
102    o pkg/atm_phys:
103      - add some diagnostics for Short-wave and for convection S/R.
104    o pkg/seaice/seaice_growth:
105      - fix a bug in the lateral melt parameterization for SEAICE_ITD
106        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
107      - rearrange loop order for better vector code in the same code block
108      - rewrite the floeDiameter formula to have fewer divisions
109      -  (miraculously) none of this changes the results of seaice_itd
110    o pkg/smooth:
111      - move param smooth2Ddiffnbt to pkg/ecco
112    o pkg/salt_plume:
113      - salt_plume_frac.F:
114         clean up local param names
115         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
116    o pkg/rw:
117      - add RS version of S/R READ_MFLDS_LEV.
118    o pkg/streamice:
119      - fix the restart test by writing/reading pickup_streamice files.
120    o pkg/seaice:
121      - refine checks for jfnk-related parameters
122      - comment out if statement with SEAICEuseIMEX parameter as long as there
123        is no IMEX code to avoid confusion and surprises
124    
125    checkpoint64u (2014/03/07)
126    o verification/MLAdjust:
127      - rename secondary test suffix:
128         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
129         0.leithD -> AhFlxF  + switch to flux-form
130         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
131         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
132    o pkg/mom_vecinv:
133      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
134        to be before mom_calc_visc.F)
135      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
136      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
137        this is simpler for the adjoint and for diagnostics.
138    o model/src + pkg/momentum:
139      - add input files for  2-D additional Western and Southern cell-edge wall
140         (e.g., to add "thin-wall" where it is =1).
141      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
142        using 2nd hFacZ that is computed from initial (fix domain) hFac
143      - known limitations of thin wall implementation: not yet coded for sigma
144        coords; not working with CD-scheme neither.
145    o pkg/seaice:
146      - rename recently introduced parameters from (wrong name) AB to
147        BDF (backward difference time discretisation)
148      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
149    o tools/adjoint_options:
150      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
151    
152    checkpoint64t (2014/02/01)
153    o pkg/ecco
154      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
155        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
156      - replace hard-coded record number and period which only work for monthly
157        with read-in runtime param that works for other periods (month,day,year)
158    o pkg/thsice
159      - corrected store directive fixes thsice adjoint gradient checks
160    o genmake2 & testreport:
161      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
162        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
163        Update testreport accordingly. No need to set "export OPENAD=true"
164        in adjoint_options/adjoint_oad anymore (will be removed later).
165    o pkg/shelfice:
166      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
167        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
168        so that surface forcing applies to k=kSurf if using pkg/shelfice.
169    o pkg/ctrl, pkg/grdchk, pkg/ecco:
170      - Changes to make GENARR more modular (i.e. invisible if not used)
171    o model/src/temp_integrate.F and salt_integrate.F
172      - re-include store directives that were removed on Dec 27th.
173    o model/src/external_forcing_surf.F
174      - add storage directives for EmPmR and PmEpR to avoid recomputation of
175        seaice_model in the adjoint that is problematic when seaice_model is
176        turned off in the adjoint. The resolved issue dated back to July when
177        EXTERNAL_FORCING_SURF call was moved.
178        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
179    o pkg/exf/exf_check.F
180      - fix a small bug again (originally found by Wentao Liu, now found again)
181      - streamline error output
182    o pkg/streamice and aim_v23:
183      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
184        Apple's /usr/bin/cpp knows what to do:
185        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
186        Target: x86_64-apple-darwin13.0.0
187    
188    checkpoint64s (2014/01/05)
189    o tools/adjoint_options:
190      - switch to fastopt.net TAF server (instead of default fastopt.de) for
191        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
192    o model/src:
193      - remove some unnecessary TAF storage directives in forward_step.F and
194        in dynamics.F (note: not always removed by TAF, e.g., double storage
195        of kappaRU,kappaRV in former version of dynamics.F).
196    o model/src & pkg/ptracers:
197      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
198        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
199        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
200      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
201      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
202      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
203    o useSingleCpuInput separates single-CPU input from single-CPU output;
204        for now only implemented for in exf_interp_read.F
205    o verification/advect_xy:
206      - fix missing EXCH call in local version of ini_salt.F and update output.
207    o momentum diagnostics:
208      - fix which deltaT is used in Total-Tendency diagnostics.
209      - fix typo in diagnostics for momentum tendency from AB.
210    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
211        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
212    
213    checkpoint64r (2013/12/08)
214    o verification/*/results:
215      - Update reference output of experiments that were passing with just 13 digits
216         (make it easier to detect future changes in results)
217    o model/src & pkg/ptracers:
218      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
219        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
220        to inside ptracers_integrate.F ; remove ptracers_advection.F
221    o coupling interface pkgs:
222        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
223      - change the config check to test the agreement of Ocean Depth
224        with ATM land/sea mask (instead of ATM orography);
225      - send to coupler the number of coupler time-steps to do for this run:
226        this allows to check for consistency and don't need anymore to be
227        specified in parameter file "data";
228      in coupler:
229      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
230      - improve report to log-file of config setting (pass log-file unit to few S/R)
231    o pkg/compon_communic:
232      - add coupling send/receive for non-tiled integer vector;
233      - add S/R to check and stop if any proc has an error (similar to
234        eesupp/src/stop_if_error.F but single thread and across Comm_World).
235    o pkg/exch2:
236      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
237        through list of all tiles my proc owns.
238    o model/src:
239      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
240        from rTrans) to simplify dependencies (no need to store rTrans anymore in
241        calling S/R); this affects AD results at machine truncation level:
242        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
243        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
244    o tools/build_options:
245      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
246    o coupling interface pkgs:
247        [compon_communic, atm_compon_interf & ocn_compon_interf]
248      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
249        to each S/R that needs it; remove un-used variables.
250      - change component tile registration (cpl_register.F in both compon_interf
251        and mitcomponent_tile_register.F) to pass the full list of tiles
252        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
253      - with pkg/exch2: adopt the same convention used for I/O to define mapping
254        towards coupler global array (unless W2_useE2ioLayOut=F):
255         a) can now use different tiling between atm & ocn comp.
256         b) no needs to modify the run-Off map when changing tiling (was needed
257            even if using the same tiling between atm & ocn).
258         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
259            full land tiles); not yet tested.
260      - check for valid mapping from comp. tile to coupler global array
261      - improve report of tile registration results to log file.
262    o pkg/exch2:
263      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
264        tile-registration (CPL_REGISTER);
265      - activate (un-comment) definition and setting of "W2_tileIndex" list to
266        store the local bi,bj indices of each tile;
267      - also print bi,bj in local report to log file;
268      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
269        Jun 2009 modif of pkg/exch2).
270    o testing on baudelaire:
271      - run 2 tests at a time: no significant slow down (since enough cpu) and
272        get the full set of test done earlier
273      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
274    o model/src/thermodynamics.F and routines called from it:
275      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
276        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
277        velocity (outp) by adding bolus velocity.
278      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
279        mass transport from velocity + lateral grid cell area
280      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
281      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
282     in thermodynamics.F
283      - remove k from thermodynamics.F and move it to temp_integrate.F
284        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
285        loop).
286      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
287        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
288        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
289        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
290      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
291        global_ocean.90x40x15, tutorial_global_oce_biogeo and
292        tutorial_tracer_adjsens (+ TLM output).
293    o tools/OAD_support and (verification/*/) code_oad:
294      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
295        module conversion ; remove unneeded CPP_EEOPTIONS.h.
296      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
297        version (closer to model/inc/CPP_OPTIONS.h).
298    o model/src:
299      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
300        retired list of parameters (routine FREEZE has been replace by surface
301        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
302    o pkg/gmredi:
303      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
304        velocity (same scheme but affects machine truncation) for GM_AdvForm.
305      - update output of FWD experiments: front_relax.bvp,
306        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
307    
308    checkpoint64q (2013/11/17)
309    o verification:
310      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
311        tutorial_global_oce_biogeo and global_ocean.90x40x15.
312      - generate new output (growth & melt) for seaice_itd experiment after
313        updating the input pickup_seaice files (previously wrong).
314    o pkg/cost:
315      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
316        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
317        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
318          cannot be applied to var in common block).
319        o allows to get results independent of tile-per-proc setting (if using
320          slower GLOBAL_SUM_SEND_RECV option).
321      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
322        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
323        forward gradients: update output).
324      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
325        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
326    o pkg/mom_common:
327      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
328        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
329        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
330        ensure that all field value that are used are set.
331    o tutorial_deep_convection (smag3d):
332      - add missing scaling in mom_calc_smag_3d.F;
333      - set smag3D_coeff in input.smag3d such that results do not change.
334    o pkg/dic:
335      - change dic_cost.F to compute cost on each tile first and then apply
336        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
337        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
338      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
339    o eesupp/src & pkg/mdsio:
340      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
341        (from pkg/mdsio) since they are no longer used for tape IO.
342      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
343        (+ keep a copy in pkg/atm_ocn_coupler).
344    o verification/isomip:
345      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
346    o tools/build_options:
347      - optfile linux_amd64_ifort11, fast (no ieee) case:
348        to get a working restart for all experiments, add "-fp-model source"
349        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
350    
351    checkpoint64p (2013/10/20)
352    o pkg/autodiff:
353      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
354        criteria, return to simple (default) tape IO format.
355    o pkg/mdsio (+ eesupp/src):
356      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
357        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
358      - fix globalFile and singleCpuIO options using simpler global mapping.
359      - new pairs of scatter/gather vector S/R (one for each type, generated from
360        template) corresponding to simpler global mapping.
361      - adread_write.F: switch to new S/R (but leave old calls commented) and write
362        to globalFile when parameter globalFiles is set to True.
363      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
364    o pkg/autodiff:
365      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
366        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
367        missing, just add a STOP if array type do not match.
368  o pkg/exf:  o pkg/exf:
369    - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:    - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
370       rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION       rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
