4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src and several pkgs:
8      - change argument list of all S/R called from external_forcing.F and
9        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
10        to pass, as argument, the current level tendency array to update
11        (instead of a direct update of the common bloc array).
12      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
13      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
14    o pkg/seaice/seaice_lsr.F
15      - always initialize local arrays in seaice_lsr_tridiagu/v
16      - add more local tapes to seaice_lsr_tridiagu/v
17      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
18        keep it in bi/bj loop; this seems to be essential
19      - gradients are still wrong but only by 4-7 orders of magnitude
20        instead of 15 orders of magnitude, lab_sea improves a little
21    o pkg/seaice
22      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
23        generates unnecessary code in seaice_lsr_ad
24      - add more store directives in seaice_lsr to avoid unnecessary code
25        in seaice_lsr_ad
26      - exclude some residual computations in seaice_lsr when
27        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
28        in seaice_lsr_ad
29      - add more storing, a new tape (model/src/the_main_loop.F) and
30        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
31        and klockey should be checked by a specialist)
32      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
33        and update lab_sea after previous changes in pkg/seaice below
34    o pkg/autodiff:
35      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
36        viscFacInAd : run time parameters allowing for adjoint switches
37        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
38    o pkg/ecco:
39      - introduce cost_gencost_boxmean.F that computes a box mean
40        temperature (for use in adjoint sensitivity studies).
41    o model/src/set_defaults.F : initialize viscFacAdj to 1.
42    o pkg/mom_common/mom_calc_visc.F:
43      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
44    o pkg/seaice/seaice_summary.F:
45      - statement for SEAICEadjMODE now in autodiff_readparms.F
46    o pkg/seaice:
47      - remove some store directives and add new ones in an effort to get
48        finally rid off the recomputation warnings. This is successful
49        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
50        defined (i.e. no extensive recomputation warnings left), but there
51        are still too many recomputations on the solver iteration level
52      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
53      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
54        SEAICE_SIZE.h
55      - add a store directive in S/R seaice_calc_viscosities
56    o pkg/seaice (ITD code):
57      - fix definition of Hlimit for multi-threaded case
58      - use double precision arithmetic to compute Hlimit: this affects results;
59        update output of experiment seaice_itd.
60    o replace content of verification/seaice_itd
61      - instead of a 1D column use the configuration of offline_exf_seaice
62        to test the ice thickness distribution code with ridging
63      - this is a first shot at this experiment
64      - change of some defaults of ridging parameters SEAICEhStar (from
65        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
66        and lot of new comments.
67    
68    checkpoint64y (2014/06/20)
69    o pkg/seaice/seaice_reg_ridge.F:
70      - modify the regularization of very small volumes of ice; only check
71        total volume HEFF, and do not apply correction to individual ice
72        classes because that leads to funny patterns in the heat and fw-fluxes
73        into the ocean. Adjust seaice_itd/results/output.txt
74      - replace nITD by SEAICE_multDim in loop-ranges
75    o pkg/exf:
76      - add code to process the case field period = -12. with UV interpolation.
77      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
78        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
79    o verification/global_with_exf:
80      - switch all fields period to -12. (was previously untested) in input/data.exf
81        (but keep secondary test ".yearly" unchanged); update the reference output.
82    o pkg/cal:
83      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
84    o pkg/exf:
85      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
86        to replace logical switch "exf_verbose"
87      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
88    o pkg/sbo:
89      - update from Katherine Quinn: evaluate mass directly from density and SSH
90        (budget using Finite Volume method) instead of from bottom pressure.
91      - allow testreport to collect few selected SBO output ; tested in exp.
92        global_ocean.90x40x15 (after updating the results, to include SBO output).
93      - fix some multi-threading issues (in output part).
94    o model/src & most packages:
95      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
96      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
97        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
98        "data.{pkg}" exist ; and leave the S/R (return) just after.
99      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
100        + call LAND_READPARMS from packages_readparms.F
101    o pkg/seaice:
102      - remove code that resets useThSice in S/R seaice_readparms and
103        replace it by a warning in S/R seaice_check
104      - remove parameter MULTDIM, replace with nITD and runtime
105        parameter SEAICE_multDim (still hard-wired to nITD if
106        SEAICE_ITD is defined)
107    
108    checkpoint64x (2014/05/24)
109    o verification/lab_sea:
110      - update adjoint and TLM output following changes to pkg/salt_plume
111      - un-do the update after putting back local recip_Cp in few places.
112    o pkg/salt_plume: modifications by An Nguyen:
113      - add capability to do brine rejection (salt-plume) as function of
114        volume+tracers (instead of only salinity tracer).
115      - conserve volume by exchanging volume from each kLev to above to
116        accommodate in-coming brine volume
117      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
118      - switch KPP surf buoyancy due to brine forcing to 3-d
119        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
120      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
121      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
122        in East/West Arctic.
123    o pkg/sbo:
124      - incorporate modifications from Katherine Quinn to enable the use of sbo
125        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
126        output for future testreport verification (unfinished).
127    o pkg/atm_phys:
128      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
129        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
130        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
131    o pkg/seaice
132      seaice_calc_ice_strength.F: modify expression to avoid divisions
133        (affects truncation)
134      seaice_do_ridging.F: clean up the insectarium
135      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
136      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
137      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
138      - add some debugging information and error messages (warnings)
139    o model/src: modifications relatd to atmosphere p*:
140      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
141      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
142        of vertical profile tRef in geopotential background and anomaly.
143      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
144        and pkg/atm_phys.
145      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
146        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
147    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
148    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
149        not used right now, but can be used in BGC packages to fix conservation.
150    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
151        other packages too.
152    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
153        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
154    o model/src:
155      - since we have several heat capacity (even in model/src), define "recip_Cp"
156        as local variable (no longer in common block) to avoid any confusion.
157      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
158    o pkg/exf:
159      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
160        air density as function of air Temp, Humidity and atm pressure.
161    
162    checkpoint64w (2014/05/02)
163    o verification:
164      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
165        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
166        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
167        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
168        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
169    o model/src: for atmosphere in p* coords:
170      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
171      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
172        but not yet activated.
173    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
174      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
175      - this changes the results (but not for any verification experiment, because
176        none tests this), but avoids having an extra field in the restart files
177    o pkg/seaice: remove global variable TICE (not needed)
178      - replace by TICES or local variable where necessary (cost_seaice_test,
179        seaice_diagnostics_state)
180      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
181      - use specific read/write routines for reading and writing individual leves
182        of a multilevel field
183    o pkg/ctrl & model/inc:
184      - move additional anomaly fields of control vars (related to options:
185         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
186        from DYNVARS.h into new header file: CTRL_FIELDS.h
187    o pkg/seaice: some small modifications to the ridging code
188      - make fw2ObyRidge a global variable and add the freshwater flux to
189        seaice_growth
190      - pass actual thickness from seaice_prepare_ridging, so that it is
191        computed only in one place and compute it in the same way as in
192        seaice_growth
193      - initialise more fields in seaice_do_ridging that where cause floating
194        point exceptions over land
195    o pkg/seaice: preparations for ridging code and first real ridging code
196      - move most of "PART 1" of S/R seaice_growth into a new and separate
197        S/R seaice_reg_ridge that will both regularize the state variable after
198        advection call the actual ridging routine;
199      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
200        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
201      - remove ridging code from seaice_advdiff
202      - clean up remaining part 1 of seaice_growth in an attempt to make it
203        more readable (this is probably subjective)
204      - call seaice_itd_redist once in the initialisation phase to have the initial
205        conditions in the correct category
206      - finally: add new ridging routine for ITD code
207    
208    checkpoint64v (2014/04/11)
209    o pkg/ecco:
210      - add runtime parameters mdt[start,end]date[1,2]
211      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
212    o pkg/seaice:
213      - make deltaC a global variable, so that it can be used in ridging code
214      - first step towards ridging: introduce new routines that compute
215        ice strength based on ridging parameters
216      - add diagnostic for HSNOWITD
217      - add opnWtrFrac as a global variable (required for ridging scheme)
218    o pkg/salt_plume + pkg/seaice/seaice_growth.F
219      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
220        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
221    o verification/hs94.1x64x5:
222      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
223      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
224    o autodiff:
225      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
226        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
227        For now, only in pkgs used in verification/hs94.1x64x5.
228      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
229        which are specific to TAF/TAMC).
230      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
231        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
232        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
233      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
234        building mitgcmuv_ad (make adAll).
235    o pkg/ecco:
236      - cost_gencost_seaicev4.F:
237         reformulate proxy cost as function of sst and local param SEAICE_freeze
238         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
239      - add stop statement if old names siv4-[sst,vol] are used
240      - add snapshots + cost reports for atmospheric longwave
241      - remove factor 0.1 in front of wtau[u,v]
242      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
243         ALLOW_TMI_SST_COST_CONTRIBUTION
244    o pkg/atm_phys:
245      - add some diagnostics for Short-wave and for convection S/R.
246    o pkg/seaice/seaice_growth:
247      - fix a bug in the lateral melt parameterization for SEAICE_ITD
248        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
249      - rearrange loop order for better vector code in the same code block
250      - rewrite the floeDiameter formula to have fewer divisions
251      -  (miraculously) none of this changes the results of seaice_itd
252    o pkg/smooth:
253      - move param smooth2Ddiffnbt to pkg/ecco
254    o pkg/salt_plume:
255      - salt_plume_frac.F:
256         clean up local param names
257         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
258    o pkg/rw:
259      - add RS version of S/R READ_MFLDS_LEV.
260    o pkg/streamice:
261      - fix the restart test by writing/reading pickup_streamice files.
262    o pkg/seaice:
263      - refine checks for jfnk-related parameters
264      - comment out if statement with SEAICEuseIMEX parameter as long as there
265        is no IMEX code to avoid confusion and surprises
266    
267    checkpoint64u (2014/03/07)
268    o verification/MLAdjust:
269      - rename secondary test suffix:
270         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
271         0.leithD -> AhFlxF  + switch to flux-form
272         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
273         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
274    o pkg/mom_vecinv:
275      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
276        to be before mom_calc_visc.F)
277      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
278      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
279        this is simpler for the adjoint and for diagnostics.
280    o model/src + pkg/momentum:
281      - add input files for  2-D additional Western and Southern cell-edge wall
282         (e.g., to add "thin-wall" where it is =1).
283      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
284        using 2nd hFacZ that is computed from initial (fix domain) hFac
285      - known limitations of thin wall implementation: not yet coded for sigma
286        coords; not working with CD-scheme neither.
287    o pkg/seaice:
288      - rename recently introduced parameters from (wrong name) AB to
289        BDF (backward difference time discretisation)
290      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
291    o tools/adjoint_options:
292      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
293    
294    checkpoint64t (2014/02/01)
295    o pkg/ecco
296      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
297        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
298      - replace hard-coded record number and period which only work for monthly
299        with read-in runtime param that works for other periods (month,day,year)
300    o pkg/thsice
301      - corrected store directive fixes thsice adjoint gradient checks
302    o genmake2 & testreport:
303      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
304        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
305        Update testreport accordingly. No need to set "export OPENAD=true"
306        in adjoint_options/adjoint_oad anymore (will be removed later).
307    o pkg/shelfice:
308      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
309        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
310        so that surface forcing applies to k=kSurf if using pkg/shelfice.
311    o pkg/ctrl, pkg/grdchk, pkg/ecco:
312      - Changes to make GENARR more modular (i.e. invisible if not used)
313    o model/src/temp_integrate.F and salt_integrate.F
314      - re-include store directives that were removed on Dec 27th.
315    o model/src/external_forcing_surf.F
316      - add storage directives for EmPmR and PmEpR to avoid recomputation of
317        seaice_model in the adjoint that is problematic when seaice_model is
318        turned off in the adjoint. The resolved issue dated back to July when
319        EXTERNAL_FORCING_SURF call was moved.
320        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
321    o pkg/exf/exf_check.F
322      - fix a small bug again (originally found by Wentao Liu, now found again)
323      - streamline error output
324    o pkg/streamice and aim_v23:
325      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
326        Apple's /usr/bin/cpp knows what to do:
327        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
328        Target: x86_64-apple-darwin13.0.0
329    
330    checkpoint64s (2014/01/05)
331    o tools/adjoint_options:
332      - switch to fastopt.net TAF server (instead of default fastopt.de) for
333        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
334    o model/src:
335      - remove some unnecessary TAF storage directives in forward_step.F and
336        in dynamics.F (note: not always removed by TAF, e.g., double storage
337        of kappaRU,kappaRV in former version of dynamics.F).
338    o model/src & pkg/ptracers:
339      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
340        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
341        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
342      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
343      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
344      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
345    o useSingleCpuInput separates single-CPU input from single-CPU output;
346        for now only implemented for in exf_interp_read.F
347    o verification/advect_xy:
348      - fix missing EXCH call in local version of ini_salt.F and update output.
349    o momentum diagnostics:
350      - fix which deltaT is used in Total-Tendency diagnostics.
351      - fix typo in diagnostics for momentum tendency from AB.
352    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
353        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
354    
355    checkpoint64r (2013/12/08)
356    o verification/*/results:
357      - Update reference output of experiments that were passing with just 13 digits
358         (make it easier to detect future changes in results)
359    o model/src & pkg/ptracers:
360      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
361        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
362        to inside ptracers_integrate.F ; remove ptracers_advection.F
363    o coupling interface pkgs:
364        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
365      - change the config check to test the agreement of Ocean Depth
366        with ATM land/sea mask (instead of ATM orography);
367      - send to coupler the number of coupler time-steps to do for this run:
368        this allows to check for consistency and don't need anymore to be
369        specified in parameter file "data";
370      in coupler:
371      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
372      - improve report to log-file of config setting (pass log-file unit to few S/R)
373    o pkg/compon_communic:
374      - add coupling send/receive for non-tiled integer vector;
375      - add S/R to check and stop if any proc has an error (similar to
376        eesupp/src/stop_if_error.F but single thread and across Comm_World).
377    o pkg/exch2:
378      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
379        through list of all tiles my proc owns.
380    o model/src:
381      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
382        from rTrans) to simplify dependencies (no need to store rTrans anymore in
383        calling S/R); this affects AD results at machine truncation level:
384        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
385        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
386    o tools/build_options:
387      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
388    o coupling interface pkgs:
389        [compon_communic, atm_compon_interf & ocn_compon_interf]
390      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
391        to each S/R that needs it; remove un-used variables.
392      - change component tile registration (cpl_register.F in both compon_interf
393        and mitcomponent_tile_register.F) to pass the full list of tiles
394        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
395      - with pkg/exch2: adopt the same convention used for I/O to define mapping
396        towards coupler global array (unless W2_useE2ioLayOut=F):
397         a) can now use different tiling between atm & ocn comp.
398         b) no needs to modify the run-Off map when changing tiling (was needed
399            even if using the same tiling between atm & ocn).
400         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
401            full land tiles); not yet tested.
402      - check for valid mapping from comp. tile to coupler global array
403      - improve report of tile registration results to log file.
404    o pkg/exch2:
405      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
406        tile-registration (CPL_REGISTER);
407      - activate (un-comment) definition and setting of "W2_tileIndex" list to
408        store the local bi,bj indices of each tile;
409      - also print bi,bj in local report to log file;
410      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
411        Jun 2009 modif of pkg/exch2).
412    o testing on baudelaire:
413      - run 2 tests at a time: no significant slow down (since enough cpu) and
414        get the full set of test done earlier
415      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
416    o model/src/thermodynamics.F and routines called from it:
417      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
418        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
419        velocity (outp) by adding bolus velocity.
420      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
421        mass transport from velocity + lateral grid cell area
422      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
423      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
424     in thermodynamics.F
425      - remove k from thermodynamics.F and move it to temp_integrate.F
426        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
427        loop).
428      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
429        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
430        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
431        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
432      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
433        global_ocean.90x40x15, tutorial_global_oce_biogeo and
434        tutorial_tracer_adjsens (+ TLM output).
435    o tools/OAD_support and (verification/*/) code_oad:
436      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
437        module conversion ; remove unneeded CPP_EEOPTIONS.h.
438      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
439        version (closer to model/inc/CPP_OPTIONS.h).
440    o model/src:
441      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
442        retired list of parameters (routine FREEZE has been replace by surface
443        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
444    o pkg/gmredi:
445      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
446        velocity (same scheme but affects machine truncation) for GM_AdvForm.
447      - update output of FWD experiments: front_relax.bvp,
448        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
449    
450    checkpoint64q (2013/11/17)
451    o verification:
452      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
453        tutorial_global_oce_biogeo and global_ocean.90x40x15.
454      - generate new output (growth & melt) for seaice_itd experiment after
455        updating the input pickup_seaice files (previously wrong).
456    o pkg/cost:
457      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
458        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
459        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
460          cannot be applied to var in common block).
461        o allows to get results independent of tile-per-proc setting (if using
462          slower GLOBAL_SUM_SEND_RECV option).
463      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
464        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
465        forward gradients: update output).
466      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
467        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
468    o pkg/mom_common:
469      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
470        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
471        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
472        ensure that all field value that are used are set.
473    o tutorial_deep_convection (smag3d):
474      - add missing scaling in mom_calc_smag_3d.F;
475      - set smag3D_coeff in input.smag3d such that results do not change.
476    o pkg/dic:
477      - change dic_cost.F to compute cost on each tile first and then apply
478        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
479        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
480      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
481    o eesupp/src & pkg/mdsio:
482      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
483        (from pkg/mdsio) since they are no longer used for tape IO.
484      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
485        (+ keep a copy in pkg/atm_ocn_coupler).
486    o verification/isomip:
487      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
488    o tools/build_options:
489      - optfile linux_amd64_ifort11, fast (no ieee) case:
490        to get a working restart for all experiments, add "-fp-model source"
491        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
492    
493    checkpoint64p (2013/10/20)
494    o pkg/autodiff:
495      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
496        criteria, return to simple (default) tape IO format.
497    o pkg/mdsio (+ eesupp/src):
498      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
499        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
500      - fix globalFile and singleCpuIO options using simpler global mapping.
501      - new pairs of scatter/gather vector S/R (one for each type, generated from
502        template) corresponding to simpler global mapping.
503      - adread_write.F: switch to new S/R (but leave old calls commented) and write
504        to globalFile when parameter globalFiles is set to True.
505      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
506    o pkg/autodiff:
507      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
508        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
509        missing, just add a STOP if array type do not match.
510    o pkg/exf:
511      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
512         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
513         and rename array obsSIce to exf_iceFraction.
514    o tutorial_deep_convection:
515      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
516        for now all in this exp. code dir.
517      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
518        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
519    o eesupp/src:
520      - added SINGLE_DISK_IO option because reading of parameter files on
521        very large number of processors did not work with existing set-up
522    
523    checkpoint64o (2013/09/25)
524    o pkg/atm_phys & atm_compon_interf:
525      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
526    o tools/build_options:
527      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
528        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
529        remove CPP setting (was identical to genmake2 default).
530    o pkg/gmredi & model/src: Some updating and work done on the residual model.
531      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
532      - fixed up the calculation of the eddy stress and how it is added to the
533        external forcing via taueddy_external_forcing.F
534      - at the moment, it is very experimental and only works with the variable eddy
535        diffusivity calculated in gmredi_k3d.F
536    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
537        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
538    o testreport (& tools/do_tst_2+2):
539      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
540    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
541      - remove CPP='cpp -traditional -P' (this is genmake2 default)
542      - add switch (for big setups) to use 'medium' memory-model (but leave it
543        commented out for now). Note: needed with FC 19 to compile big setups.
544    o pkg/atm_compon_interf:
545      - regroup per field origin (model & pkgs) the coupling storage routines
546         (which accumalate in time each coupling field)
547      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
548        update accordingly + simplify aim_do_physics.F
549    
550    checkpoint64n (2013/08/26)
551    o pkg/bbl:
552      - update formulation to reduce dispersion of tracer properties in bbl
553      - replaced horizontal and vertical transport parameters with velocities
554      - changes results for verification/global_with_exf.yearly
555    o verification/halfpipe_streamice:
556      - change to matrix construction; update both Fwd & AD output.
557    o verification/tutorial_tracer_adjsens:
558      - OpenAD test: switch to vector-invariant momentum since fluxform with
559        rStar causes problems with OpenAD; update output.
560    o tools:
561      - genmake2: define a common prefix for all temp-file names ; move them
562        to local /tmp disk (but would be easy to move them back);
563      - xmakedepend: apply the same switch for temp-files.
564    o pkg/offline:
565      - changes for use with rStar (NLFS): assume that we continue to provide
566        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
567        output files) and apply r* scaling at each time-step (function of the time
568        varying Eta field); use normal pickup files (needed for restart with NLFS).
569    o adjoint with OpenAD:
570      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
571        package openad.  This package has to be compiled for all runs with OpenAD
572        instead of specifying code_oad_all as a modification directory.
573      - link the fortran templates from tools/OAD_support to the build directory
574        for preprocessing to avoid conflicts between different setups compiled
575        simultaneously and simplify cleanup.
576    o pkg/exf:
577      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
578        main model or other pkgs are exchanged in EXF_MAPFIELDS).
579    o model/src:
580      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
581        (similar to do_fields_blocking_exchanges.F).
582    o tools/genmake2:
583      - remove TAF output src code just before calling staf (when not doing a fresh
584        built, will stop if things go wrong with staf).
585      - fix target "adobj" (left from TAF version-2 transition)
586    o pkg/diagnostics:
587      - add a parameter to track the status of pkg/diagnostics activation;
588        this replace/extend the use of logical param "settingDiags" (to check
589        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
590        New S/R to print error message and stop when pkgStatus is not right.
591      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
592    
593    checkpoint64m (2013/08/13)
594    o model/inc:
595      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
596        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
597    o pkg/kpp & aim_v23:
598      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
599    o pkg/seaice:
600      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
601        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
602      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
603    o eesupp/src:
604      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
605        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
606    o switch to TAF version-2:
607      - add flow directives to "freeze" naming convention for ad-routines that
608        are used in I/O routines of adjoint state and associated common blocks
609        that are used in adcommon.h (backward compatible with version-1)
610      - update all ad-optfiles (in tools/adjoint_options + few local to some
611        verification exp) to switch to latest TAF version (currently 2.5.5);
612        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
613        out except for diva).
614      - the major change with TAF version-2 is that both the differentiated
615        routines and the forward routines (new) are returned as part of the TAF
616        output source code. Update genmake2 accordingly.
617      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
618        with version-2 when compared to TLM or FWD gradient); other experiments
619        output show minor changes (machine truncation level); update the few AD &
620        TLM output with 12 matching digits only (some prior to version-2 switch).
621    
622    checkpoint64l (2013/08/05)
623    o model/src:
624      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
625      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
626        when using TAF but only if using OpenAD.
627    o pkg/mom_common+fluxform+vecinv:
628      - always set horiz. viscosity arrays to background value before calling
629        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
630        only when using variable horiz. viscosity (useVariableVisc=T);
631      - simplify mom_vecinv.F (only 1 block for momViscosity).
632    o pkg/mom_common: variable horiz. viscosity in NH code
633      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
634        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
635      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
636        useBiharmonicVisc & useVariableVisc.
637      - fix old bug (already in 1rst implementation of variable horizontal viscosity
638        in calc_gw.F, version 1.27, 2006/06/20):
639        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
640        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
641      - change background horiz viscosity in vertical momentum (gW) to always be
642        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
643        any type of variable viscosity, e.g., viscAh/4Grid)
644      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
645        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
646        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
647        default viscAh,viscA4 is zero).
648    o model/src:
649      - extend length of drC & recip_drC from Nr to Nr+1.
650  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
651    - genmake2: do not create local ./mpi_headers dir when no file to copy into.    - genmake2: do not create local ./mpi_headers dir when no file to copy into.
652    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
