6    
7    checkpoint64z (2014/07/10)
8    o model/src and several pkgs:
9      - change argument list of all S/R called from external_forcing.F and
10        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
11        to pass, as argument, the current level tendency array to update
12        (instead of a direct update of the common bloc array).
13      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
14      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
15    o pkg/seaice/seaice_lsr.F
16      - always initialize local arrays in seaice_lsr_tridiagu/v
17      - add more local tapes to seaice_lsr_tridiagu/v
18      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
19        keep it in bi/bj loop; this seems to be essential
20      - gradients are still wrong but only by 4-7 orders of magnitude
21        instead of 15 orders of magnitude, lab_sea improves a little
22    o pkg/seaice
23      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
24        generates unnecessary code in seaice_lsr_ad
25      - add more store directives in seaice_lsr to avoid unnecessary code
26        in seaice_lsr_ad
27      - exclude some residual computations in seaice_lsr when
28        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
29        in seaice_lsr_ad
30      - add more storing, a new tape (model/src/the_main_loop.F) and
31        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
32        and klockey should be checked by a specialist)
33      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
34        and update lab_sea after previous changes in pkg/seaice below
35    o pkg/autodiff:
36      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
37        viscFacInAd : run time parameters allowing for adjoint switches
38        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
39    o pkg/ecco:
40      - introduce cost_gencost_boxmean.F that computes a box mean
41        temperature (for use in adjoint sensitivity studies).
42    o model/src/set_defaults.F : initialize viscFacAdj to 1.
43    o pkg/mom_common/mom_calc_visc.F:
44      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
45    o pkg/seaice/seaice_summary.F:
46      - statement for SEAICEadjMODE now in autodiff_readparms.F
47    o pkg/seaice:
48      - remove some store directives and add new ones in an effort to get
49        finally rid off the recomputation warnings. This is successful
50        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
51        defined (i.e. no extensive recomputation warnings left), but there
52        are still too many recomputations on the solver iteration level
53      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
54      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
55        SEAICE_SIZE.h
56      - add a store directive in S/R seaice_calc_viscosities
57    o pkg/seaice (ITD code):
58      - fix definition of Hlimit for multi-threaded case
59      - use double precision arithmetic to compute Hlimit: this affects results;
60        update output of experiment seaice_itd.
61    o replace content of verification/seaice_itd
62      - instead of a 1D column use the configuration of offline_exf_seaice
63        to test the ice thickness distribution code with ridging
64      - this is a first shot at this experiment
65      - change of some defaults of ridging parameters SEAICEhStar (from
66        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
67        and lot of new comments.
68    
69    checkpoint64y (2014/06/20)
70    o pkg/seaice/seaice_reg_ridge.F:
71      - modify the regularization of very small volumes of ice; only check
72        total volume HEFF, and do not apply correction to individual ice
73        classes because that leads to funny patterns in the heat and fw-fluxes
74        into the ocean. Adjust seaice_itd/results/output.txt
75      - replace nITD by SEAICE_multDim in loop-ranges
76    o pkg/exf:
77      - add code to process the case field period = -12. with UV interpolation.
78      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
79        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
80    o verification/global_with_exf:
81      - switch all fields period to -12. (was previously untested) in input/data.exf
82        (but keep secondary test ".yearly" unchanged); update the reference output.
83    o pkg/cal:
84      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
85    o pkg/exf:
86      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
87        to replace logical switch "exf_verbose"
88      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
89    o pkg/sbo:
90      - update from Katherine Quinn: evaluate mass directly from density and SSH
91        (budget using Finite Volume method) instead of from bottom pressure.
92      - allow testreport to collect few selected SBO output ; tested in exp.
93        global_ocean.90x40x15 (after updating the results, to include SBO output).
94      - fix some multi-threading issues (in output part).
95    o model/src & most packages:
96      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
97      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
98        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
99        "data.{pkg}" exist ; and leave the S/R (return) just after.
100      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
101        + call LAND_READPARMS from packages_readparms.F
102    o pkg/seaice:
103      - remove code that resets useThSice in S/R seaice_readparms and
104        replace it by a warning in S/R seaice_check
105      - remove parameter MULTDIM, replace with nITD and runtime
106        parameter SEAICE_multDim (still hard-wired to nITD if
107        SEAICE_ITD is defined)
108    
109    checkpoint64x (2014/05/24)
110    o verification/lab_sea:
111      - update adjoint and TLM output following changes to pkg/salt_plume
112      - un-do the update after putting back local recip_Cp in few places.
113    o pkg/salt_plume: modifications by An Nguyen:
114      - add capability to do brine rejection (salt-plume) as function of
115        volume+tracers (instead of only salinity tracer).
116      - conserve volume by exchanging volume from each kLev to above to
117        accommodate in-coming brine volume
118      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
119      - switch KPP surf buoyancy due to brine forcing to 3-d
120        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
121      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
122      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
123        in East/West Arctic.
124    o pkg/sbo:
125      - incorporate modifications from Katherine Quinn to enable the use of sbo
126        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
127        output for future testreport verification (unfinished).
128    o pkg/atm_phys:
129      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
130        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
131        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
132    o pkg/seaice
133      seaice_calc_ice_strength.F: modify expression to avoid divisions
134        (affects truncation)
135      seaice_do_ridging.F: clean up the insectarium
136      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
137      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
138      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
139      - add some debugging information and error messages (warnings)
140    o model/src: modifications relatd to atmosphere p*:
141      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
142      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
143        of vertical profile tRef in geopotential background and anomaly.
144      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
145        and pkg/atm_phys.
146      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
147        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
148    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
149    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
150        not used right now, but can be used in BGC packages to fix conservation.
151    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
152        other packages too.
153    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
154        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
155    o model/src:
156      - since we have several heat capacity (even in model/src), define "recip_Cp"
157        as local variable (no longer in common block) to avoid any confusion.
158      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
159    o pkg/exf:
160      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
161        air density as function of air Temp, Humidity and atm pressure.
162    
163    checkpoint64w (2014/05/02)
164    o verification:
165      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
166        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
167        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
168        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
169        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
170    o model/src: for atmosphere in p* coords:
171      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
172      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
173        but not yet activated.
174    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
175      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
176      - this changes the results (but not for any verification experiment, because
177        none tests this), but avoids having an extra field in the restart files
178    o pkg/seaice: remove global variable TICE (not needed)
179      - replace by TICES or local variable where necessary (cost_seaice_test,
180        seaice_diagnostics_state)
181      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
182      - use specific read/write routines for reading and writing individual leves
183        of a multilevel field
184    o pkg/ctrl & model/inc:
185      - move additional anomaly fields of control vars (related to options:
186         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
187        from DYNVARS.h into new header file: CTRL_FIELDS.h
188    o pkg/seaice: some small modifications to the ridging code
189      - make fw2ObyRidge a global variable and add the freshwater flux to
190        seaice_growth
191      - pass actual thickness from seaice_prepare_ridging, so that it is
192        computed only in one place and compute it in the same way as in
193        seaice_growth
194      - initialise more fields in seaice_do_ridging that where cause floating
195        point exceptions over land
196    o pkg/seaice: preparations for ridging code and first real ridging code
197      - move most of "PART 1" of S/R seaice_growth into a new and separate
198        S/R seaice_reg_ridge that will both regularize the state variable after
199        advection call the actual ridging routine;
200      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
201        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
202      - remove ridging code from seaice_advdiff
203      - clean up remaining part 1 of seaice_growth in an attempt to make it
204        more readable (this is probably subjective)
205      - call seaice_itd_redist once in the initialisation phase to have the initial
206        conditions in the correct category
207      - finally: add new ridging routine for ITD code
208    
209    checkpoint64v (2014/04/11)
210    o pkg/ecco:
211      - add runtime parameters mdt[start,end]date[1,2]
212      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
213    o pkg/seaice:
214      - make deltaC a global variable, so that it can be used in ridging code
215      - first step towards ridging: introduce new routines that compute
216        ice strength based on ridging parameters
217      - add diagnostic for HSNOWITD
218      - add opnWtrFrac as a global variable (required for ridging scheme)
219    o pkg/salt_plume + pkg/seaice/seaice_growth.F
220      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
221        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
222    o verification/hs94.1x64x5:
223      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
224      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
225    o autodiff:
226      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
227        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
228        For now, only in pkgs used in verification/hs94.1x64x5.
229      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
230        which are specific to TAF/TAMC).
231      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
232        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
233        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
234      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
235        building mitgcmuv_ad (make adAll).
236    o pkg/ecco:
237      - cost_gencost_seaicev4.F:
238         reformulate proxy cost as function of sst and local param SEAICE_freeze
239         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
240      - add stop statement if old names siv4-[sst,vol] are used
241      - add snapshots + cost reports for atmospheric longwave
242      - remove factor 0.1 in front of wtau[u,v]
243      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
244         ALLOW_TMI_SST_COST_CONTRIBUTION
245    o pkg/atm_phys:
246      - add some diagnostics for Short-wave and for convection S/R.
247    o pkg/seaice/seaice_growth:
248      - fix a bug in the lateral melt parameterization for SEAICE_ITD
249        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
250      - rearrange loop order for better vector code in the same code block
251      - rewrite the floeDiameter formula to have fewer divisions
252      -  (miraculously) none of this changes the results of seaice_itd
253    o pkg/smooth:
254      - move param smooth2Ddiffnbt to pkg/ecco
255    o pkg/salt_plume:
256      - salt_plume_frac.F:
257         clean up local param names
258         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
259    o pkg/rw:
260      - add RS version of S/R READ_MFLDS_LEV.
261    o pkg/streamice:
262      - fix the restart test by writing/reading pickup_streamice files.
263    o pkg/seaice:
264      - refine checks for jfnk-related parameters
265      - comment out if statement with SEAICEuseIMEX parameter as long as there
266        is no IMEX code to avoid confusion and surprises
267    
268    checkpoint64u (2014/03/07)
269    o verification/MLAdjust:
270      - rename secondary test suffix:
271         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
272         0.leithD -> AhFlxF  + switch to flux-form
273         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
274         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
275    o pkg/mom_vecinv:
276      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
277        to be before mom_calc_visc.F)
278      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
279      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
280        this is simpler for the adjoint and for diagnostics.
281    o model/src + pkg/momentum:
282      - add input files for  2-D additional Western and Southern cell-edge wall
283         (e.g., to add "thin-wall" where it is =1).
284      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
285        using 2nd hFacZ that is computed from initial (fix domain) hFac
286      - known limitations of thin wall implementation: not yet coded for sigma
287        coords; not working with CD-scheme neither.
288    o pkg/seaice:
289      - rename recently introduced parameters from (wrong name) AB to
290        BDF (backward difference time discretisation)
291      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
292    o tools/adjoint_options:
293      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
294    
295    checkpoint64t (2014/02/01)
296    o pkg/ecco
297      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
298        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
299      - replace hard-coded record number and period which only work for monthly
300        with read-in runtime param that works for other periods (month,day,year)
301    o pkg/thsice
302      - corrected store directive fixes thsice adjoint gradient checks
303    o genmake2 & testreport:
304      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
305        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
306        Update testreport accordingly. No need to set "export OPENAD=true"
307        in adjoint_options/adjoint_oad anymore (will be removed later).
308    o pkg/shelfice:
309      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
310        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
311        so that surface forcing applies to k=kSurf if using pkg/shelfice.
312    o pkg/ctrl, pkg/grdchk, pkg/ecco:
313      - Changes to make GENARR more modular (i.e. invisible if not used)
314    o model/src/temp_integrate.F and salt_integrate.F
315      - re-include store directives that were removed on Dec 27th.
316    o model/src/external_forcing_surf.F
317      - add storage directives for EmPmR and PmEpR to avoid recomputation of
318        seaice_model in the adjoint that is problematic when seaice_model is
319        turned off in the adjoint. The resolved issue dated back to July when
320        EXTERNAL_FORCING_SURF call was moved.
321        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
322    o pkg/exf/exf_check.F
323      - fix a small bug again (originally found by Wentao Liu, now found again)
324      - streamline error output
325    o pkg/streamice and aim_v23:
326      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
327        Apple's /usr/bin/cpp knows what to do:
328        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
329        Target: x86_64-apple-darwin13.0.0
330    
331    checkpoint64s (2014/01/05)
332    o tools/adjoint_options:
333      - switch to fastopt.net TAF server (instead of default fastopt.de) for
334        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
335    o model/src:
336      - remove some unnecessary TAF storage directives in forward_step.F and
337        in dynamics.F (note: not always removed by TAF, e.g., double storage
338        of kappaRU,kappaRV in former version of dynamics.F).
339    o model/src & pkg/ptracers:
340      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
341        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
342        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
343      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
344      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
345      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
346    o useSingleCpuInput separates single-CPU input from single-CPU output;
347        for now only implemented for in exf_interp_read.F
348    o verification/advect_xy:
349      - fix missing EXCH call in local version of ini_salt.F and update output.
350    o momentum diagnostics:
351      - fix which deltaT is used in Total-Tendency diagnostics.
352      - fix typo in diagnostics for momentum tendency from AB.
353    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
354        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
355    
356    checkpoint64r (2013/12/08)
357    o verification/*/results:
358      - Update reference output of experiments that were passing with just 13 digits
359         (make it easier to detect future changes in results)
360    o model/src & pkg/ptracers:
361      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
362        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
363        to inside ptracers_integrate.F ; remove ptracers_advection.F
364    o coupling interface pkgs:
365        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
366      - change the config check to test the agreement of Ocean Depth
367        with ATM land/sea mask (instead of ATM orography);
368      - send to coupler the number of coupler time-steps to do for this run:
369        this allows to check for consistency and don't need anymore to be
370        specified in parameter file "data";
371      in coupler:
372      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
373      - improve report to log-file of config setting (pass log-file unit to few S/R)
374    o pkg/compon_communic:
375      - add coupling send/receive for non-tiled integer vector;
376      - add S/R to check and stop if any proc has an error (similar to
377        eesupp/src/stop_if_error.F but single thread and across Comm_World).
378    o pkg/exch2:
379      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
380        through list of all tiles my proc owns.
381    o model/src:
382      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
383        from rTrans) to simplify dependencies (no need to store rTrans anymore in
384        calling S/R); this affects AD results at machine truncation level:
385        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
386        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
387    o tools/build_options:
388      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
389    o coupling interface pkgs:
390        [compon_communic, atm_compon_interf & ocn_compon_interf]
391      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
392        to each S/R that needs it; remove un-used variables.
393      - change component tile registration (cpl_register.F in both compon_interf
394        and mitcomponent_tile_register.F) to pass the full list of tiles
395        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
396      - with pkg/exch2: adopt the same convention used for I/O to define mapping
397        towards coupler global array (unless W2_useE2ioLayOut=F):
398         a) can now use different tiling between atm & ocn comp.
399         b) no needs to modify the run-Off map when changing tiling (was needed
400            even if using the same tiling between atm & ocn).
401         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
402            full land tiles); not yet tested.
403      - check for valid mapping from comp. tile to coupler global array
404      - improve report of tile registration results to log file.
405    o pkg/exch2:
406      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
407        tile-registration (CPL_REGISTER);
408      - activate (un-comment) definition and setting of "W2_tileIndex" list to
409        store the local bi,bj indices of each tile;
410      - also print bi,bj in local report to log file;
411      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
412        Jun 2009 modif of pkg/exch2).
413    o testing on baudelaire:
414      - run 2 tests at a time: no significant slow down (since enough cpu) and
415        get the full set of test done earlier
416      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
417    o model/src/thermodynamics.F and routines called from it:
418      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
419        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
420        velocity (outp) by adding bolus velocity.
421      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
422        mass transport from velocity + lateral grid cell area
423      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
424      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
425     in thermodynamics.F
426      - remove k from thermodynamics.F and move it to temp_integrate.F
427        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
428        loop).
429      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
430        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
431        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
432        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
433      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
434        global_ocean.90x40x15, tutorial_global_oce_biogeo and
435        tutorial_tracer_adjsens (+ TLM output).
436    o tools/OAD_support and (verification/*/) code_oad:
437      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
438        module conversion ; remove unneeded CPP_EEOPTIONS.h.
439      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
440        version (closer to model/inc/CPP_OPTIONS.h).
441    o model/src:
442      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
443        retired list of parameters (routine FREEZE has been replace by surface
444        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
445    o pkg/gmredi:
446      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
447        velocity (same scheme but affects machine truncation) for GM_AdvForm.
448      - update output of FWD experiments: front_relax.bvp,
449        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
450    
451    checkpoint64q (2013/11/17)
452    o verification:
453      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
454        tutorial_global_oce_biogeo and global_ocean.90x40x15.
455      - generate new output (growth & melt) for seaice_itd experiment after
456        updating the input pickup_seaice files (previously wrong).
457    o pkg/cost:
458      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
459        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
460        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
461          cannot be applied to var in common block).
462        o allows to get results independent of tile-per-proc setting (if using
463          slower GLOBAL_SUM_SEND_RECV option).
464      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
465        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
466        forward gradients: update output).
467      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
468        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
469    o pkg/mom_common:
470      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
471        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
472        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
473        ensure that all field value that are used are set.
474    o tutorial_deep_convection (smag3d):
475      - add missing scaling in mom_calc_smag_3d.F;
476      - set smag3D_coeff in input.smag3d such that results do not change.
477    o pkg/dic:
478      - change dic_cost.F to compute cost on each tile first and then apply
479        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
480        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
481      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
482    o eesupp/src & pkg/mdsio:
483      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
484        (from pkg/mdsio) since they are no longer used for tape IO.
485      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
486        (+ keep a copy in pkg/atm_ocn_coupler).
487    o verification/isomip:
488      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
489    o tools/build_options:
490      - optfile linux_amd64_ifort11, fast (no ieee) case:
491        to get a working restart for all experiments, add "-fp-model source"
492        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
493    
494    checkpoint64p (2013/10/20)
495    o pkg/autodiff:
496      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
497        criteria, return to simple (default) tape IO format.
498    o pkg/mdsio (+ eesupp/src):
499      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
500        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
501      - fix globalFile and singleCpuIO options using simpler global mapping.
502      - new pairs of scatter/gather vector S/R (one for each type, generated from
503        template) corresponding to simpler global mapping.
504      - adread_write.F: switch to new S/R (but leave old calls commented) and write
505        to globalFile when parameter globalFiles is set to True.
506      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
507    o pkg/autodiff:
508      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
509        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
510        missing, just add a STOP if array type do not match.
511    o pkg/exf:
512      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
513         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
514         and rename array obsSIce to exf_iceFraction.
515    o tutorial_deep_convection:
516      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
517        for now all in this exp. code dir.
518      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
519        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
520    o eesupp/src:
521      - added SINGLE_DISK_IO option because reading of parameter files on
522        very large number of processors did not work with existing set-up
523    
524    checkpoint64o (2013/09/25)
525    o pkg/atm_phys & atm_compon_interf:
526      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
527    o tools/build_options:
528      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
529        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
530        remove CPP setting (was identical to genmake2 default).
531    o pkg/gmredi & model/src: Some updating and work done on the residual model.
532      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
533      - fixed up the calculation of the eddy stress and how it is added to the
534        external forcing via taueddy_external_forcing.F
535      - at the moment, it is very experimental and only works with the variable eddy
536        diffusivity calculated in gmredi_k3d.F
537    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
538        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
539    o testreport (& tools/do_tst_2+2):
540      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
541    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
542      - remove CPP='cpp -traditional -P' (this is genmake2 default)
543      - add switch (for big setups) to use 'medium' memory-model (but leave it
544        commented out for now). Note: needed with FC 19 to compile big setups.
545    o pkg/atm_compon_interf:
546      - regroup per field origin (model & pkgs) the coupling storage routines
547         (which accumalate in time each coupling field)
548      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
549        update accordingly + simplify aim_do_physics.F
550    
551    checkpoint64n (2013/08/26)
552    o pkg/bbl:
553      - update formulation to reduce dispersion of tracer properties in bbl
554      - replaced horizontal and vertical transport parameters with velocities
555      - changes results for verification/global_with_exf.yearly
556    o verification/halfpipe_streamice:
557      - change to matrix construction; update both Fwd & AD output.
558    o verification/tutorial_tracer_adjsens:
559      - OpenAD test: switch to vector-invariant momentum since fluxform with
560        rStar causes problems with OpenAD; update output.
561    o tools:
562      - genmake2: define a common prefix for all temp-file names ; move them
563        to local /tmp disk (but would be easy to move them back);
564      - xmakedepend: apply the same switch for temp-files.
565    o pkg/offline:
566      - changes for use with rStar (NLFS): assume that we continue to provide
567        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
568        output files) and apply r* scaling at each time-step (function of the time
569        varying Eta field); use normal pickup files (needed for restart with NLFS).
570    o adjoint with OpenAD:
571      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
572        package openad.  This package has to be compiled for all runs with OpenAD
573        instead of specifying code_oad_all as a modification directory.
574      - link the fortran templates from tools/OAD_support to the build directory
575        for preprocessing to avoid conflicts between different setups compiled
576        simultaneously and simplify cleanup.
577    o pkg/exf:
578      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
579        main model or other pkgs are exchanged in EXF_MAPFIELDS).
580    o model/src:
581      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
582        (similar to do_fields_blocking_exchanges.F).
583    o tools/genmake2:
584      - remove TAF output src code just before calling staf (when not doing a fresh
585        built, will stop if things go wrong with staf).
586      - fix target "adobj" (left from TAF version-2 transition)
587    o pkg/diagnostics:
588      - add a parameter to track the status of pkg/diagnostics activation;
589        this replace/extend the use of logical param "settingDiags" (to check
590        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
591        New S/R to print error message and stop when pkgStatus is not right.
592      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
593    
594    checkpoint64m (2013/08/13)
595    o model/inc:
596      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
597        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
598    o pkg/kpp & aim_v23:
599      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
600    o pkg/seaice:
601      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
602        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
603      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
604    o eesupp/src:
605      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
606        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
607    o switch to TAF version-2:
608      - add flow directives to "freeze" naming convention for ad-routines that
609        are used in I/O routines of adjoint state and associated common blocks
610        that are used in adcommon.h (backward compatible with version-1)
611      - update all ad-optfiles (in tools/adjoint_options + few local to some
612        verification exp) to switch to latest TAF version (currently 2.5.5);
613        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
614        out except for diva).
615      - the major change with TAF version-2 is that both the differentiated
616        routines and the forward routines (new) are returned as part of the TAF
617        output source code. Update genmake2 accordingly.
618      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
619        with version-2 when compared to TLM or FWD gradient); other experiments
620        output show minor changes (machine truncation level); update the few AD &
621        TLM output with 12 matching digits only (some prior to version-2 switch).
622    
623    checkpoint64l (2013/08/05)
624    o model/src:
625      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
626      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
627        when using TAF but only if using OpenAD.
628    o pkg/mom_common+fluxform+vecinv:
629      - always set horiz. viscosity arrays to background value before calling
630        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
631        only when using variable horiz. viscosity (useVariableVisc=T);
632      - simplify mom_vecinv.F (only 1 block for momViscosity).
633    o pkg/mom_common: variable horiz. viscosity in NH code
634      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
635        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
636      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
637        useBiharmonicVisc & useVariableVisc.
638      - fix old bug (already in 1rst implementation of variable horizontal viscosity
639        in calc_gw.F, version 1.27, 2006/06/20):
640        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
641        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
642      - change background horiz viscosity in vertical momentum (gW) to always be
643        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
644        any type of variable viscosity, e.g., viscAh/4Grid)
645      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
646        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
647        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
648        default viscAh,viscA4 is zero).
649    o model/src:
650      - extend length of drC & recip_drC from Nr to Nr+1.
651    o Divided Adjoint (DIVA) with MPI:
652      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
653      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
654        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
655    
656    checkpoint64k (2013/07/23)
657    o tools/OAD_support:
658      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
659        and remove it from genmake2.
660    o tools/build_options:
661      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
662        MPI_HEADER_FILES list (let genmake2 find the missing headers)
663    o verification/halfpipe_streamice:
664      - change to driving stress formulation; update both Fwd & AD output.
665    o tools/genmake2 and Divided Adjoint with MPI:
666      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
667      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
668      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
669        Makefile, which is set by genmake2, and check which mpi-headers are needed.
670        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
