4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_reg_ridge.F:
8      - modify the regularization of very small volumes of ice; only check
9        total volume HEFF, and do not apply correction to individual ice
10        classes because that leads to funny patterns in the heat and fw-fluxes
11        into the ocean. Adjust seaice_itd/results/output.txt
12      - replace nITD by SEAICE_multDim in loop-ranges
13    o pkg/exf:
14      - add code to process the case field period = -12. with UV interpolation.
15      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
16        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
17    o verification/global_with_exf:
18      - swith all fields period to -12. (was previously untested) in input/data.exf
19        (but keep secondary test ".yearly" unchanged); update the reference output.
20    o pkg/cal:
21      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
22    o pkg/exf:
23      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
24        to replace logical switch "exf_verbose"
25      - report in STDOUT when loading a new reccord (if exf_debugLev >= 3)
26    o pkg/sbo:
27      - update from Katherine Quinn: evaluate mass directly from density and SSH
28        (budget using Finite Volume method) instead of from bottom pressure.
29      - allow testreport to collect few selected SBO output ; tested in exp.
30        global_ocean.90x40x15 (after updating the results, to include SBO output).
31      - fix some multi-threading issues (in output part).
32    o model/src & most packages:
33      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
34      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
35        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
36        "data.{pkg}" exist ; and leave the S/R (return) just after.
37      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
38        + call LAND_READPARMS from packages_readparms.F
39    o pkg/seaice:
40      - remove code that resets useThSice in S/R seaice_readparms and
41        replace it by a warning in S/R seaice_check
42      - remove parameter MULTDIM, replace with nITD and runtime
43        parameter SEAICE_multDim (still hard-wired to nITD if
44        SEAICE_ITD is defined)
45    
46    checkpoint64x (2014/05/24)
47    o verification/lab_sea:
48      - update adjoint and TLM output following changes to pkg/salt_plume
49      - un-do the update after putting back local recip_Cp in few places.
50    o pkg/salt_plume: modifications by An Nguyen:
51      - add capability to do brine rejection (salt-plume) as function of
52        volume+tracers (instead of only salinity tracer).
53      - conserve volume by exchanging volume from each kLev to above to
54        accommodate in-coming brine volume
55      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
56      - switch KPP surf buoyancy due to brine forcing to 3-d
57        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
58      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
59      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
60        in East/West Arctic.
61    o pkg/sbo:
62      - incorporate modifications from Katherine Quinn to enable the use of sbo
63        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
64        output for future testreport verification (unfinished).
65    o pkg/atm_phys:
66      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
67        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
68        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
69    o pkg/seaice
70      seaice_calc_ice_strength.F: modify expression to avoid divisions
71        (affects truncation)
72      seaice_do_ridging.F: clean up the insectarium
73      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
74      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
75      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
76      - add some debugging information and error messages (warnings)
77    o model/src: modifications relatd to atmosphere p*:
78      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
79      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
80        of vertical profile tRef in geopotential background and anomaly.
81      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
82        and pkg/atm_phys.
83      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
84        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
85    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
86    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
87        not used right now, but can be used in BGC packages to fix conservation.
88    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
89        other packages too.
90    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
91        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
92    o model/src:
93      - since we have several heat capacity (even in model/src), define "recip_Cp"
94        as local variable (no longer in common block) to avoid any confusion.
95      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
96    o pkg/exf:
97      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
98        air density as function of air Temp, Humidity and atm pressure.
99    
100    checkpoint64w (2014/05/02)
101    o verification:
102      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
103        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
104        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
105        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
106        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
107    o model/src: for atmosphere in p* coords:
108      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
109      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
110        but not yet activated.
111    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
112      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
113      - this changes the results (but not for any verification experiment, because
114        none tests this), but avoids having an extra field in the restart files
115    o pkg/seaice: remove global variable TICE (not needed)
116      - replace by TICES or local variable where necessary (cost_seaice_test,
117        seaice_diagnostics_state)
118      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
119      - use specific read/write routines for reading and writing individual leves
120        of a multilevel field
121    o pkg/ctrl & model/inc:
122      - move additional anomaly fields of control vars (related to options:
123         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
124        from DYNVARS.h into new header file: CTRL_FIELDS.h
125    o pkg/seaice: some small modifications to the ridging code
126      - make fw2ObyRidge a global variable and add the freshwater flux to
127        seaice_growth
128      - pass actual thickness from seaice_prepare_ridging, so that it is
129        computed only in one place and compute it in the same way as in
130        seaice_growth
131      - initialise more fields in seaice_do_ridging that where cause floating
132        point exceptions over land
133    o pkg/seaice: preparations for ridging code and first real ridging code
134      - move most of "PART 1" of S/R seaice_growth into a new and separate
135        S/R seaice_reg_ridge that will both regularize the state variable after
136        advection call the actual ridging routine;
137      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
138        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
139      - remove ridging code from seaice_advdiff
140      - clean up remaining part 1 of seaice_growth in an attempt to make it
141        more readable (this is probably subjective)
142      - call seaice_itd_redist once in the initialisation phase to have the initial
143        conditions in the correct category
144      - finally: add new ridging routine for ITD code
145    
146    checkpoint64v (2014/04/11)
147    o pkg/ecco:
148      - add runtime parameters mdt[start,end]date[1,2]
149      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
150    o pkg/seaice:
151      - make deltaC a global variable, so that it can be used in ridging code
152      - first step towards ridging: introduce new routines that compute
153        ice strength based on ridging parameters
154      - add diagnostic for HSNOWITD
155      - add opnWtrFrac as a global variable (required for ridging scheme)
156    o pkg/salt_plume + pkg/seaice/seaice_growth.F
157      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
158        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
159    o verification/hs94.1x64x5:
160      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
161      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
162    o autodiff:
163      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
164        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
165        For now, only in pkgs used in verification/hs94.1x64x5.
166      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
167        which are specific to TAF/TAMC).
168      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
169        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
170        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
171      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
172        building mitgcmuv_ad (make adAll).
173    o pkg/ecco:
174      - cost_gencost_seaicev4.F:
175         reformulate proxy cost as function of sst and local param SEAICE_freeze
176         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
177      - add stop statement if old names siv4-[sst,vol] are used
178      - add snapshots + cost reports for atmospheric longwave
179      - remove factor 0.1 in front of wtau[u,v]
180      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
181         ALLOW_TMI_SST_COST_CONTRIBUTION
182    o pkg/atm_phys:
183      - add some diagnostics for Short-wave and for convection S/R.
184    o pkg/seaice/seaice_growth:
185      - fix a bug in the lateral melt parameterization for SEAICE_ITD
186        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
187      - rearrange loop order for better vector code in the same code block
188      - rewrite the floeDiameter formula to have fewer divisions
189      -  (miraculously) none of this changes the results of seaice_itd
190    o pkg/smooth:
191      - move param smooth2Ddiffnbt to pkg/ecco
192    o pkg/salt_plume:
193      - salt_plume_frac.F:
194         clean up local param names
195         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
196    o pkg/rw:
197      - add RS version of S/R READ_MFLDS_LEV.
198    o pkg/streamice:
199      - fix the restart test by writing/reading pickup_streamice files.
200    o pkg/seaice:
201      - refine checks for jfnk-related parameters
202      - comment out if statement with SEAICEuseIMEX parameter as long as there
203        is no IMEX code to avoid confusion and surprises
204    
205    checkpoint64u (2014/03/07)
206    o verification/MLAdjust:
207      - rename secondary test suffix:
208         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
209         0.leithD -> AhFlxF  + switch to flux-form
210         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
211         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
212    o pkg/mom_vecinv:
213      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
214        to be before mom_calc_visc.F)
215      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
216      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
217        this is simpler for the adjoint and for diagnostics.
218    o model/src + pkg/momentum:
219      - add input files for  2-D additional Western and Southern cell-edge wall
220         (e.g., to add "thin-wall" where it is =1).
221      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
222        using 2nd hFacZ that is computed from initial (fix domain) hFac
223      - known limitations of thin wall implementation: not yet coded for sigma
224        coords; not working with CD-scheme neither.
225    o pkg/seaice:
226      - rename recently introduced parameters from (wrong name) AB to
227        BDF (backward difference time discretisation)
228      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
229    o tools/adjoint_options:
230      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
231    
232    checkpoint64t (2014/02/01)
233    o pkg/ecco
234      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
235        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
236      - replace hard-coded record number and period which only work for monthly
237        with read-in runtime param that works for other periods (month,day,year)
238    o pkg/thsice
239      - corrected store directive fixes thsice adjoint gradient checks
240    o genmake2 & testreport:
241      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
242        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
243        Update testreport accordingly. No need to set "export OPENAD=true"
244        in adjoint_options/adjoint_oad anymore (will be removed later).
245    o pkg/shelfice:
246      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
247        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
248        so that surface forcing applies to k=kSurf if using pkg/shelfice.
249    o pkg/ctrl, pkg/grdchk, pkg/ecco:
250      - Changes to make GENARR more modular (i.e. invisible if not used)
251    o model/src/temp_integrate.F and salt_integrate.F
252      - re-include store directives that were removed on Dec 27th.
253    o model/src/external_forcing_surf.F
254      - add storage directives for EmPmR and PmEpR to avoid recomputation of
255        seaice_model in the adjoint that is problematic when seaice_model is
256        turned off in the adjoint. The resolved issue dated back to July when
257        EXTERNAL_FORCING_SURF call was moved.
258        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
259    o pkg/exf/exf_check.F
260      - fix a small bug again (originally found by Wentao Liu, now found again)
261      - streamline error output
262    o pkg/streamice and aim_v23:
263      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
264        Apple's /usr/bin/cpp knows what to do:
265        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
266        Target: x86_64-apple-darwin13.0.0
267    
268    checkpoint64s (2014/01/05)
269    o tools/adjoint_options:
270      - switch to fastopt.net TAF server (instead of default fastopt.de) for
271        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
272    o model/src:
273      - remove some unnecessary TAF storage directives in forward_step.F and
274        in dynamics.F (note: not always removed by TAF, e.g., double storage
275        of kappaRU,kappaRV in former version of dynamics.F).
276    o model/src & pkg/ptracers:
277      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
278        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
279        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
280      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
281      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
282      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
283    o useSingleCpuInput separates single-CPU input from single-CPU output;
284        for now only implemented for in exf_interp_read.F
285    o verification/advect_xy:
286      - fix missing EXCH call in local version of ini_salt.F and update output.
287    o momentum diagnostics:
288      - fix which deltaT is used in Total-Tendency diagnostics.
289      - fix typo in diagnostics for momentum tendency from AB.
290    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
291        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
292    
293    checkpoint64r (2013/12/08)
294    o verification/*/results:
295      - Update reference output of experiments that were passing with just 13 digits
296         (make it easier to detect future changes in results)
297    o model/src & pkg/ptracers:
298      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
299        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
300        to inside ptracers_integrate.F ; remove ptracers_advection.F
301    o coupling interface pkgs:
302        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
303      - change the config check to test the agreement of Ocean Depth
304        with ATM land/sea mask (instead of ATM orography);
305      - send to coupler the number of coupler time-steps to do for this run:
306        this allows to check for consistency and don't need anymore to be
307        specified in parameter file "data";
308      in coupler:
309      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
310      - improve report to log-file of config setting (pass log-file unit to few S/R)
311    o pkg/compon_communic:
312      - add coupling send/receive for non-tiled integer vector;
313      - add S/R to check and stop if any proc has an error (similar to
314        eesupp/src/stop_if_error.F but single thread and across Comm_World).
315    o pkg/exch2:
316      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
317        through list of all tiles my proc owns.
318    o model/src:
319      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
320        from rTrans) to simplify dependencies (no need to store rTrans anymore in
321        calling S/R); this affects AD results at machine truncation level:
322        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
323        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
324    o tools/build_options:
325      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
326    o coupling interface pkgs:
327        [compon_communic, atm_compon_interf & ocn_compon_interf]
328      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
329        to each S/R that needs it; remove un-used variables.
330      - change component tile registration (cpl_register.F in both compon_interf
331        and mitcomponent_tile_register.F) to pass the full list of tiles
332        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
333      - with pkg/exch2: adopt the same convention used for I/O to define mapping
334        towards coupler global array (unless W2_useE2ioLayOut=F):
335         a) can now use different tiling between atm & ocn comp.
336         b) no needs to modify the run-Off map when changing tiling (was needed
337            even if using the same tiling between atm & ocn).
338         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
339            full land tiles); not yet tested.
340      - check for valid mapping from comp. tile to coupler global array
341      - improve report of tile registration results to log file.
342    o pkg/exch2:
343      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
344        tile-registration (CPL_REGISTER);
345      - activate (un-comment) definition and setting of "W2_tileIndex" list to
346        store the local bi,bj indices of each tile;
347      - also print bi,bj in local report to log file;
348      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
349        Jun 2009 modif of pkg/exch2).
350    o testing on baudelaire:
351      - run 2 tests at a time: no significant slow down (since enough cpu) and
352        get the full set of test done earlier
353      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
354    o model/src/thermodynamics.F and routines called from it:
355      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
356        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
357        velocity (outp) by adding bolus velocity.
358      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
359        mass transport from velocity + lateral grid cell area
360      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
361      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
362     in thermodynamics.F
363      - remove k from thermodynamics.F and move it to temp_integrate.F
364        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
365        loop).
366      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
367        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
368        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
369        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
370      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
371        global_ocean.90x40x15, tutorial_global_oce_biogeo and
372        tutorial_tracer_adjsens (+ TLM output).
373    o tools/OAD_support and (verification/*/) code_oad:
374      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
375        module conversion ; remove unneeded CPP_EEOPTIONS.h.
376      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
377        version (closer to model/inc/CPP_OPTIONS.h).
378    o model/src:
379      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
380        retired list of parameters (routine FREEZE has been replace by surface
381        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
382    o pkg/gmredi:
383      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
384        velocity (same scheme but affects machine truncation) for GM_AdvForm.
385      - update output of FWD experiments: front_relax.bvp,
386        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
387    
388    checkpoint64q (2013/11/17)
389    o verification:
390      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
391        tutorial_global_oce_biogeo and global_ocean.90x40x15.
392      - generate new output (growth & melt) for seaice_itd experiment after
393        updating the input pickup_seaice files (previously wrong).
394    o pkg/cost:
395      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
396        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
397        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
398          cannot be applied to var in common block).
399        o allows to get results independent of tile-per-proc setting (if using
400          slower GLOBAL_SUM_SEND_RECV option).
401      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
402        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
403        forward gradients: update output).
404      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
405        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
406    o pkg/mom_common:
407      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
408        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
409        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
410        ensure that all field value that are used are set.
411    o tutorial_deep_convection (smag3d):
412      - add missing scaling in mom_calc_smag_3d.F;
413      - set smag3D_coeff in input.smag3d such that results do not change.
414    o pkg/dic:
415      - change dic_cost.F to compute cost on each tile first and then apply
416        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
417        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
418      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
419    o eesupp/src & pkg/mdsio:
420      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
421        (from pkg/mdsio) since they are no longer used for tape IO.
422      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
423        (+ keep a copy in pkg/atm_ocn_coupler).
424    o verification/isomip:
425      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
426    o tools/build_options:
427      - optfile linux_amd64_ifort11, fast (no ieee) case:
428        to get a working restart for all experiments, add "-fp-model source"
429        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
430    
431    checkpoint64p (2013/10/20)
432    o pkg/autodiff:
433      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
434        criteria, return to simple (default) tape IO format.
435    o pkg/mdsio (+ eesupp/src):
436      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
437        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
438      - fix globalFile and singleCpuIO options using simpler global mapping.
439      - new pairs of scatter/gather vector S/R (one for each type, generated from
440        template) corresponding to simpler global mapping.
441      - adread_write.F: switch to new S/R (but leave old calls commented) and write
442        to globalFile when parameter globalFiles is set to True.
443      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
444    o pkg/autodiff:
445      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
446        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
447        missing, just add a STOP if array type do not match.
448    o pkg/exf:
449      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
450         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
451         and rename array obsSIce to exf_iceFraction.
452    o tutorial_deep_convection:
453      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
454        for now all in this exp. code dir.
455      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
456        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
457    o eesupp/src:
458      - added SINGLE_DISK_IO option because reading of parameter files on
459        very large number of processors did not work with existing set-up
460    
461    checkpoint64o (2013/09/25)
462    o pkg/atm_phys & atm_compon_interf:
463      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
464    o tools/build_options:
465      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
466        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
467        remove CPP setting (was identical to genmake2 default).
468    o pkg/gmredi & model/src: Some updating and work done on the residual model.
469      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
470      - fixed up the calculation of the eddy stress and how it is added to the
471        external forcing via taueddy_external_forcing.F
472      - at the moment, it is very experimental and only works with the variable eddy
473        diffusivity calculated in gmredi_k3d.F
474    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
475        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
476    o testreport (& tools/do_tst_2+2):
477      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
478    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
479      - remove CPP='cpp -traditional -P' (this is genmake2 default)
480      - add switch (for big setups) to use 'medium' memory-model (but leave it
481        commented out for now). Note: needed with FC 19 to compile big setups.
482    o pkg/atm_compon_interf:
483      - regroup per field origin (model & pkgs) the coupling storage routines
484         (which accumalate in time each coupling field)
485      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
486        update accordingly + simplify aim_do_physics.F
487    
488    checkpoint64n (2013/08/26)
489    o pkg/bbl:
490      - update formulation to reduce dispersion of tracer properties in bbl
491      - replaced horizontal and vertical transport parameters with velocities
492      - changes results for verification/global_with_exf.yearly
493    o verification/halfpipe_streamice:
494      - change to matrix construction; update both Fwd & AD output.
495    o verification/tutorial_tracer_adjsens:
496      - OpenAD test: switch to vector-invariant momentum since fluxform with
497        rStar causes problems with OpenAD; update output.
498    o tools:
499      - genmake2: define a common prefix for all temp-file names ; move them
500        to local /tmp disk (but would be easy to move them back);
501      - xmakedepend: apply the same switch for temp-files.
502    o pkg/offline:
503      - changes for use with rStar (NLFS): assume that we continue to provide
504        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
505        output files) and apply r* scaling at each time-step (function of the time
506        varying Eta field); use normal pickup files (needed for restart with NLFS).
507    o adjoint with OpenAD:
508      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
509        package openad.  This package has to be compiled for all runs with OpenAD
510        instead of specifying code_oad_all as a modification directory.
511      - link the fortran templates from tools/OAD_support to the build directory
512        for preprocessing to avoid conflicts between different setups compiled
513        simultaneously and simplify cleanup.
514    o pkg/exf:
515      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
516        main model or other pkgs are exchanged in EXF_MAPFIELDS).
517    o model/src:
518      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
519        (similar to do_fields_blocking_exchanges.F).
520    o tools/genmake2:
521      - remove TAF output src code just before calling staf (when not doing a fresh
522        built, will stop if things go wrong with staf).
523      - fix target "adobj" (left from TAF version-2 transition)
524    o pkg/diagnostics:
525      - add a parameter to track the status of pkg/diagnostics activation;
526        this replace/extend the use of logical param "settingDiags" (to check
527        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
528        New S/R to print error message and stop when pkgStatus is not right.
529      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
530    
531    checkpoint64m (2013/08/13)
532    o model/inc:
533      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
534        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
535    o pkg/kpp & aim_v23:
536      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
537    o pkg/seaice:
538      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
539        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
540      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
541    o eesupp/src:
542      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
543        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
544    o switch to TAF version-2:
545      - add flow directives to "freeze" naming convention for ad-routines that
546        are used in I/O routines of adjoint state and associated common blocks
547        that are used in adcommon.h (backward compatible with version-1)
548      - update all ad-optfiles (in tools/adjoint_options + few local to some
549        verification exp) to switch to latest TAF version (currently 2.5.5);
550        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
551        out except for diva).
552      - the major change with TAF version-2 is that both the differentiated
553        routines and the forward routines (new) are returned as part of the TAF
554        output source code. Update genmake2 accordingly.
555      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
556        with version-2 when compared to TLM or FWD gradient); other experiments
557        output show minor changes (machine truncation level); update the few AD &
558        TLM output with 12 matching digits only (some prior to version-2 switch).
559    
560    checkpoint64l (2013/08/05)
561    o model/src:
562      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
563      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
564        when using TAF but only if using OpenAD.
565    o pkg/mom_common+fluxform+vecinv:
566      - always set horiz. viscosity arrays to background value before calling
567        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
568        only when using variable horiz. viscosity (useVariableVisc=T);
569      - simplify mom_vecinv.F (only 1 block for momViscosity).
570    o pkg/mom_common: variable horiz. viscosity in NH code
571      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
572        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
573      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
574        useBiharmonicVisc & useVariableVisc.
575      - fix old bug (already in 1rst implementation of variable horizontal viscosity
576        in calc_gw.F, version 1.27, 2006/06/20):
577        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
578        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
579      - change background horiz viscosity in vertical momentum (gW) to always be
580        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
581        any type of variable viscosity, e.g., viscAh/4Grid)
582      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
583        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
584        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
585        default viscAh,viscA4 is zero).
586    o model/src:
587      - extend length of drC & recip_drC from Nr to Nr+1.
588    o Divided Adjoint (DIVA) with MPI:
589      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
590      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
591        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
592    
593    checkpoint64k (2013/07/23)
594    o tools/OAD_support:
595      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
596        and remove it from genmake2.
597    o tools/build_options:
598      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
599        MPI_HEADER_FILES list (let genmake2 find the missing headers)
600    o verification/halfpipe_streamice:
601      - change to driving stress formulation; update both Fwd & AD output.
602    o tools/genmake2 and Divided Adjoint with MPI:
603      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
604      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
605      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
606        Makefile, which is set by genmake2, and check which mpi-headers are needed.
607        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
608      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
609    o testreport:
610      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
611        perform additional runs (number of additional runs is "add_DIVA_runs" taken
612        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
613    o verification/lab_sea (AD test):
614      - change to test Divided Adjoint Run in this set-up (both standard AD test
615        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
616    o pkg atm_ & ocn_compon_interf:
617      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
618        staggerTimeStep implementation) and disable (retired) corresponding
619        parameter.
620    o pkg/offline:
621      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
622      - add S/R OFFLINE_CHECK to print offline parameter summary
623        and stop if loading a file that is not used;
624      - enable to calculate GMRedi tensor, KPP mixing and convective index
625        when the corresponding file(s) is/are not specified (but pkg is used).
626      - comment out resetting of monitorFreq (to endTime) since it still useful
627        for monitoring CFL numbers and checking offline fields.
628    o OpenAD:
629      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
630        smaller standard output) and generate new (smaller) output (on baudelaire
631        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
632    o model/src:
633      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
634        (where external_forcing_adjust was called) and change list of arguments;
635      - merge external_forcing_adjust.F into external_forcing_surf.F
636      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
637        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
638        previously in file "balance_relax.F", now removed); remove corresponding
639        arrays in FFIELDS.h.
640      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
641        a hack for getting back surfaceForcingS (loaded from file) when using
642        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
643      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
644        (was getting only 11 digits for AD-grad, due to different truncation
645         error in AD code).
646    
647    checkpoint64j (2013/07/04)
648    o pkg/offline:
649      - to enable the use of other features with pkg offline (e.g., obcs),
650        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
651      - comment out "allowFreezing" (now active) in 2 offline testing exp.
652  o pkg/exf ALLOW_RUNOFTEMP  o pkg/exf ALLOW_RUNOFTEMP
653    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
654    - added RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice    - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
655    - changes verification/global_ocean.cs32x15/results/output.seaice.txt    - changes verification/global_ocean.cs32x15/results/output.seaice.txt
656  o pkg/atm_phys:  o pkg/atm_phys:
657    - allows to add some damping on uVel,vVel (strength only function of k).    - allows to add some damping on uVel,vVel (strength only function of k).
