4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - to check restart test, add option to apply EXCH to U,V earlier, just before
9        integr_continuity; turned off by default.
10    o pkg/dic:
11      - remove CPP option USE_ATMOSCO2 (not needed)
12    o tools/tst_2+2:
13      - try to ignore difference between +0 and -0 in binary file, causing test
14        to fail for no good reason.
15    o eesupp & genmake2:
16      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
17        but also check (in genmake2) that test runs and returns meaningful results.
18    o coupler pkgs:
19      Finish implementation of optionally-exchanged variable switches (started on
20       Nov 12) with addition of few more exchanged fields, including 2-way exchange
21       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
22       advection in OCN component; this requires sequential coupling.
23      coupler (pkg/atm_ocn_coupler):
24      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
25        routines (useful for debug).
26      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
27         flux, DIC fields) if corresponding switch is ON.
28      - add option to export RunOff to OCN (to use for DIC river input)
29      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
30      components (pkg/atm_ & ocn_compon_interf):
31      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
32        optionally exchanged fields; add a check & stop in cpl_readparms.F.
33        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
34        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
35      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
36        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
37      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
38      - hold in common block coupler optionally-exchanged variable switch
39        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
40      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
41        this is intended to replace the OCN cplFldtave.* output files (not updated
42        to contain new additional exchanged fields).
43    o pkg/dic:
44      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
45    o pkg/thsice:
46      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
47        and writing of thsice pickup files.
48    o pkg/atm_compon_interf:
49      - move all field individual export-call out of cpl_export_import_data.F
50        into new S/R ATM_EXPORT_FIELDS
51    o pkg/atm_compon_interf:
52      - store state variables (for now, only thSIce fields) just before beeing
53        exported (in cpl_export_import_data.F, like on ocean side) instead of from
54        atm_store_my_data.F like all exported fluxes.
55      - new version of pickup_cpl: write field names into meta file and read meta
56        file to find field postion in pickup. Also only write/read fields meeded for
57        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
58    o pkg/dic:
59      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
60    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
61        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
62        value can be from domain [0,1] to average between the two methods
63    o pkg/atm_phys:
64      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
65        hold fixed in time).
66    
67    checkpoint65r (2015/12/21)
68    o pkg/seaice:
69        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
70        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
71    o pkg/seaice:
72      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
73        when SEAICEscaleSurfStress=.TRUE.,
74      - apply areaW and areaS in S/R seaice_calc_lhs
75    o pkg/atm_phys:
76      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
77        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
78        for individual contribution (convection, LSC cond, radiation)
79      - add Ruth Geen etal, GRL 2016, radiation optionis (see paper supp.
80        information); activated with: solar_exponent=0. and wv_exponent=-1.
81    o pkg/ggl90:
82      - within IDEMIX add upper limit for horizontal group velocity to
83        avoid instability problems in the explicit horizontal diffusion term for
84        long time steps or high resolution
85    o pkg/diagnostics:
86      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
87        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
88    o testreport:
89      - remove "-v" (verbose option) in default mpirun command.
90    o pkg/seaice/seaice_growth:
91      - catch potential division by zero in ITD code, does not change
92        verification results
93    o pkg/ecco:
94      - retire old codes to the Attic. The calls to retired functions are
95        left in a commented form in case they ever need to be re-activated.
96      - ecco_check.F: issue warning if any old CPP option is
97        defined that corresponds to retired codes -- then stop.
98    o pkg/atm_compon_interf:
99      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
100        coupler: use last time-step value instead of average over cplSendFrq_iter
101        time-step, similar to what is done for seaIceMass.
102        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
103    o eesupp & genmake2:
104      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
105        <= remove until a fix is found for some ifort version on ia32 machine.
106    o pkg/seaice/seaice_evp:
107      - refine residual computation
108    
109    checkpoint65q (2015/11/18)
110    o pkg/seaice/seaice_evp:
111      - fix residual computations so that they no longer affect the actual
112        simulation code
113      - fix seaice_readparams to be able to actually set new parameters
114        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
115    o model/src:
116      - fix wrong truncation (single prec) from "FLOAT" function in expressions
117        like: deltaT*FLOAT(myIter) when myIter is large:
118         a) replaced by DFLOAT (if not seen by TAF);
119         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
120    o pkg/aim_v23:
121      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
122        when pickupSuff is set ; do write rolling pickups + at the end of the run.
123    o pkg/atm_ocn_coupler + ocn_compon_interf:
124      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
125        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
126        add corresponding call in DO_OCEANIC_PHYS.
127    o coupler pkgs:
128      Start a new way to set-up optionally-exchanged variables (previously, only
129       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
130       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
131       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
132       compononent param default can be set accordingly).
133      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
134       but rather applies to a group a fields (going both ways like for DIC)
135       and corresponds to an option of coupling config.
136      coupler (pkg/atm_ocn_coupler):
137      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
138        and read namelist directly (without eessup S/R calls) instead of
139        in the very un-flexible old way, 1 param per line, in fixed order;
140      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
141        cleanly in CPL_CHECK_CPLCONFIG
142      - add new coupling-exchange selectors (some not yet active) including
143        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
144                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
145      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
146        component ; called directly from coupler.F, after comp. registrations;
147      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
148         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
149          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
150      components (pkg/atm_ & ocn_compon_interf):
151      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
152        CPP header file in all pkg source files.
153      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
154        ATM/OCN_CHECK_CPLCONFIG;
155      - add error-counter to track errors (e.g., in "data.cpl") and to stop
156        cleanly in ATM/OCN_CHECK_CPLCONFIG;
157      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
158        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
159        before PACKAGES_READPARMS;
160      verification/cpl_aim+ocn/:
161      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
162        "data.cpl" for coupler (in input_cpl).
163    o eesupp/inc:
164      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
165        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
166        to always cumulate tile local-sum in the same order (still uses
167        MPI_Allreduce like standard code).
168      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
169        that are now identical to standard version (in eesupp/inc).
170    o pkg/shelfice:
171      - add SHELFICETransCoeffTFile for initializing spatially varying
172        heat and salt transfer coefficients
173    o pkg/atm_compon_interf & ocn_compon_interf:
174      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
175        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
176      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
177    o pkg/atm_ocn_coupler:
178      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
179    o pkg/rbcs:
180      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
181        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
182      - add a short report (to STDOUT) about RBCS-mask settings.
183    
184    checkpoint65p (2015/10/23)
185    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
186        there is no adjoint test for EVP, we don't know what it does to the adjoint
187        solution, but at least there are no more recomputation warnings left
188    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
189        a chance of giving the same results as a fully converged VP (JFNK) solver
190    o tools/adjoint_options/adjoint_diva:
191      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
192    o pkg/streamice:
193      - spotted bug in streamice_driving_stress using dyG where should have been dxG
194    o pkg/exf:
195      - remove STOP statement that prevented to use wind or (wind-)stress
196        interpolation for constant-in-time forcing fields (wind/stress period = 0).
197    o pkg/seaice:
198      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
199        5 additionals 2D fields and 6 new store directives
200      - change logic in seaice_readparms.F: EVP code can now be turned on in
201        various ways, setting SEAICE_deltaTev is no longer required,
202        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
203        or SEAICEaEVPcoeff
204    o pkg/shelfice/shelfice_thermodynamics.F
205      - redefining uLoc/vLoc to u/v, instead of 2u/v
206    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
207      - this is an intermediate state of a truely converging EVP that has
208        the potential of outperforming implicit VP methods, I do not recommend
209        using it yet.
210      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
211        and all parameters are hardwired
212      - for convergence it still requires very smooth regularisations, that means,
213        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
214        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
215        specific averaging appears to be required, still subject to tuning
216      - still needs cleaning and I need to turn parameter into runtime parameters
217      - add code to compute and print residuals of iteration, compile with
218        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
219    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
220      that entered with r1.54 on Sep04, 2015, -> update results
221    
222    checkpoint65o (2015/09/14)
223    o pkg/mom_vecinv & mom_common:
224      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
225        called from there.
226      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
227        allows to use Vector-Invariant form in deep atmos and anelastic formulation
228    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
229      and Koenig-Beatty+Holland (2012)
230      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
231      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
232      - requires an extra input argument for S/R seaice_calc_viscosities
233      - tensileStrength's depth dependence is different from Itkin et al. (2015)
234        (to be changed and played with, for now exponential)
235    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
236      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
237        by AREA according to Connelly et al. (2004), JPO.
238      - For EVP and the LSR solver, the implicit part of the drag term is
239        the only non-zero term in the denominator when there is no ice (which
240        prevented running the model with zero ice-ocean drag). If
241        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
242        (or zero main diagonals BU/BV) which need to be caught. A practical
243        consequence is that for open water, the momentum equation reduce
244        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
245        they happen to be zero, often leading to a non-zero solution over
246        open water.
247    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
248        efficient EVP method.
249      - introduce area-weighted averages for e12 (analogously to
250        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
251        remain, but also changing the order of terms in the previous average
252        changed the results as much) -> update experiment
253      - add SEAICE_DELTA_SMOOTHREG code
254      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
255        TEM-code
256      - adjust loop bounds so that only required fields are computed
257      - add new averaging code for zetaZ/deltaZ (again similar to
258        seaice_calc_viscosities.F), inactive by default for now (will change
259        results again), but will replace old code eventually
260    o eesupp/src:
261      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
262        to always cumulate tile local-sum in the same order
263        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
264        Still uses MPI_Allreduce (like standard code) but on array of tiles
265        and should be faster than GLOBAL_SUM_SEND_RECV code.
266      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
267        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
268      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
269         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
270         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
271         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
272         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
273    
274    checkpoint65n (2015/07/29)
275    o pkg/thsice:
276      - add a warning when used with pkg/aim but without updating SST
277        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
278    o pkg/offline:
279      - change where Offline-Fields are loaded, from load_fields_driver.F to
280        directly within FORWARD_STEP, just after updating iter number and time;
281      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
282        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
283       These changes allow:
284        a) to recover exactly on-line results using deltaToffline=deltaTClock,
285        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
286        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
287        time-step, both with GM & KPP files and with recomputing these fields;
288        b) no needs to switch on staggerTimeStep anymore;
289        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
290      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
291    o pkg/offline:
292      - change (rarely used) offset-iteration parameter to an offset time (in s):
293        can easily recover previous offset-iter effect by setting offset-time
294        (offlineTimeOffset) to offset-iter x deltaToffline;
295      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
296        in KPP as part of surface buoyancy forcing) in offline run.
297      - fix ptracers KPP non-local term in the case where KPP is re-computed.
298    o OpenAD
299      - Adding preliminary ggl90 test to OpenAD verification.
300        Config. with ggl90 currently diverges after 64 time steps
301        so will need more work to become more stable
302      - Adding preliminary kpp test to OpenAD verification.
303        required small tweakes in kpp_routines.F
304      - Merge and update from Krishna Narayanan's contrib area:
305        * Add one variable for preliminary OpenAD DIVA
306        * Add replacement time-stepping for OpenAD DIVA
307        * genmake2 flag -diva (but only for OpenAD; preliminary)
308        * required modifs for OAD_support
309        successful preliminary test for tutorial_global_oce_biogeo/
310    o pkg/seaice:
311      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
312      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
313        delta with a smooth function in s/r seaice_calc_viscosity
314        (no effect on EVP)
315      - rename local suffix "sqr" into "sq" for more consistent variable names
316    o pkg/seaice:
317        add new parameter SEAICE_deltaMin that is used ***only***
318        for regularizing Delta (and nothing else, like the parameter
319        which is also used for all sorts of things SEAICE_EPS).
320        Defaults to SEAICE_EPS for backward compatibility only.
321    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
322        the wrong key by inialising it before use -> fixes a recomputation
323        problem but does not fix the gradient
324    o pkg/layers:
325      - move resetting of flux arrays to outside the iLa loop
326        (this caused layers_diapycnal to not work with more than one layer coord.)
327      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
328    o pkg/layers:
329      - remove from common block 3D layers fields (used to diagnose transport
330        in tracer coords) and declare them as local arrays in layers_calc.F
331    o pkg/seaice:
332      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
333        in lab_sea forward experiment (changes results -> updated)
334      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
335    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
336       computations; for SEAICE_VECTORIZE_LSR
337      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
338        sweep to the outside,
339      - remove store directives and add "CADJ loop sequential" directives
340        in analogy to model/src/solve_tridiagonal.F
341      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
342        boundaries to yield more readable code. This has also the charming side
343        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
344        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
345        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
346        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
347        an additional option)
348       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
349       but the adjoint gradients (which are affected by this change) still explode.
350    o coupler (atm & ocn _compon_interf):
351      - avoid using Exch2 IO mapping if not suitable.
352    
353    checkpoint65m (2015/06/15)
354    o pkg/layers:
355      - clean-up old parameters setting (from Sep 2012):
356        + remove old parameters setting from common block (declared locally);
357        + stop if any old parameter is mixed with new parameters;
358        + check for valid or consistent parameter setting (e.g., layers_name)
359      - check that layers_bounds for Pot.Density are in the right range;
360        this is supposed to catch un-updated setting after recently shifting
361        potential density field "prho" by -1000 (now in "sigma" scale).
362    o pkg/layers:
363      - Added missing call to layers_fill for keeping track of tottend in
364        pkg/diagnostics/diagnostics_fill_state.F
365    o pkg/layers:
366      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
367        of diapycnal fluxes
368    o pkg/layers:
369      - reverted changes to interpolation to previous treatment; there
370        was never actually a problem
371    o pkg/layers:
372      - fix interpolation of layers tracers in the presence of partial cells
373      - add lots of new functionality to compute water mass transformation
374        (enabled by CPP flag LAYERS_THERMODYNAMICS)
375      - add new calls from main code (diags_oceanic_surf_flux.F,
376        thermodynamics.F, impldiff.F) and gad to save the necessary fields
377        for layers_thermodynamics calculations
378    o pkg/ptracers:
379      - add capability of stepping a passive tracer forward without advection
380        by setting PTRACERS_advScheme to 0.
381    o pkg/diagnostics:
382      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
383    o pkg/layers:
384      - shift potential density field "prho" by -1000 for density layer averaging so
385        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
386        Note that density bin boundaries (layers_bounds in data.layers) have
387        to be set accordingly (i.e., shifted, in sigma scale).
388    o pkg/layers:
389      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
390      - fix calculation of layer non-weighted velocity and layer probability
391      - add diagnostics for pot.density used for layer averaging
392    o pkg/seaice:
393      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
394        positiveness, modify a few comments and improve variable names,
395      - the changed computation of deltaC affects most seaice-related
396        experiments at the truncation level.
397        seaice_itd.thermo is affected by far the most, with
398        only 7 digits of agreement remaining; update experiments.
399    
400    checkpoint65l (2015/05/04)
401    o pkg/shelfice:
402      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
403        factor drKp1 to zero where it is negative (ie. do not use
404        SHELFICEBoundaryLayer if hFacC>1)
405      - the same for factor drLoc in shelfice_forcing.F
406    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
407        with modules in ptracers, when using testreport option "-small_f"
408    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
409      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
410    o verification/testreport
411      - add new option -small_f
412        with this option testreport first makes the target small_f (*.f files)
413        before running make (all). This is useful for explicit inlining when
414        all sources need to be full available.
415    o pkg/exf/exf_interp.F:
416        remove previous changes related to reverse (decreasing) input grids latitude
417    
418    checkpoint65k (2015/04/01)
419    o pkg/ecco:
420        fix missing cosphi initialization; use eccoiter in place of optimcycle;
421        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
422        instead of active read/write
423    o pkg/ctrl:
424        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
425        instead of active read/write.
426    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
427        return if .NOT.useAUTODIFF
428    o pkg/seaice: add CPP brackets (cost function related).
429    o model/src:
430        add useAUTODIFF run time switch.
431    o pkg/exf/exf_interp.F:
432        add code to allow input grids with latitude starting in the north (i.e. when
433        j=1 corresponds to northern edge of field); modify global_with_exf to test
434        this feature.
435    o verification/testreport:
436      - replace "grep -A3" with POSIX conformal sed command, because there are
437        implementations of grep that cannot do contextual searches
438      - replace "cat -n" by "nl" (two occurrences), because not all implementations
439        of "cat" have the option "-n"
440    o model/src:
441        add new file gsw_teos10.F that contains 3 functions, more or less a copy
442        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
443        convert from conservative to potential temperature. For now they are not
444        called anywhere.
445    o pkg/ggl90: make "useIDEMIX" useful
446      - re-organize code in s/r ggl90_calc a little to move computations that
447        are different for idemix into separate loops (changes verification
448        experiment idemix at truncation level, 12 digits remain -> updated)
449      - requires 2 new 2D fields KappaM, verticalShear
450      - make hFacI and recip_hFacI local 3D variables that are passed to
451        s/r ggl90_idemix
452      - fix and improve some comments
453    
454    checkpoint65j (2015/02/25)
455    o pkg/openad
456      - synchronize seawater.F with version in model/src: replace routine
457        body of sw_temp by calling sw_ptmp and fix/add a few comments.
458    o pkg/mnc:
459      - change default value of pickup_read/write_mnc params to FALSE
460        (since few features are missing in reading MNC pickup files).
461    o model/src:
462      - change default (background) vertical diffusivity for salt to be the
463        temperature (background) vertical diffusivity.
464      - change background vertical diffusivity in vertical mixing pkgs ggl90,
465        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
466        This makes ptracers default diffusivity (that uses salt diffKr) more
467        consistent with vertical mixing schemes.
468    o verification/testreport:
469      - fix typo in "-pcls" option ;
470      - put temp files in /tmp (instead of in local dir)
471      - add option "-ncad" to use genmake2 new option "-nocat4ad"
472      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
473    o pkg/ggl90 (idemix code):
474      - apply few fixes ; add some missing "_d 0" ; update output of exp.
475        global_ocean.90x40x15.idemix
476    o OpenAD
477      - enable active file I/O and begin removal of work-around code
478        for OpenAD for handling control variables (memory vs. active files)
479      - new CPP options file OPENAD_OPTIONS.h
480      - revert to genarr2d gradient check for hs94.1x64x5
481      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
482      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
483    o tools/genmake2:
484      - add option for an alternative Makefile (from Martin) where multiple
485        source files are sent to TAF (instead of all in one file).
486    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
487      - code provided by Carsten Eden as an extension of ggl90
488      - so far the code is turned on within ggl90 by setting a CPP-flag at
489        compile time; a runtime flag implementation is not yet complete
490      - tested in new verification experiment global_ocean.90x40x15.idemix
491    o verification:
492      - reduce length of the AD test run by half for experiments
493        global_ocean.cs32x15 (std + thsice) and isomip
494      - enable active file I/O for OpenAD, adjust verifications accordingly
495      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
496    o verification/testreport:
497      - fix two non-POSIX sed statements so that there are no error messages
498        on Mac OS X
499      - replace hostname -s with hostname | sed 's/\..*$//'
500    o model/src/seawater.F:
501      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
502        (following the matlab code), which would have avoided the bug caught
503        by Matt (see below) in the first place
504    o pkg/shelfice:
505      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
506        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
507      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
508        ice-shelf case (i.e., within surface level).
509      - add config summary in shelfice_check.F
510      - remove global variable recip_SHELFICElatentHeat and replace by a local
511        variable recip_latentHeat
512      - introduce diagnostics for friction velocity uStar (in case of
513        SHELFICEuseGammaFrict)
514      - change verification experiment isomip.htd:
515        + start from pickup (as input_ad at nIter0=8640)
516        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
517        + test SHELFICEuseGammaFrict = .TRUE.
518        + test SHELFICEadvDiffHeatFlux = .TRUE.
519    o model/src:
520      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
521        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
522        update output of experiments global_with_exf.yearly and isomip (all 6).
523    o pkg/shelfice:
524      - change setting of kTopC to also be zero where there is no ice-shelf.
525      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
526        ice-shelf is.
527      - first attempt to get RealFreshWaterFlux effects: for now, only without
528        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
529    o pkg/seaice: add the option to prescribe a fixed thickness PDF
530      for thermodynamic calculations
531      - because of divisions of the type 7/7 not exactly equal to 1, this change
532        affects results of some verification experiments by up to 4 digits:
533        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
534        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
535        adjoint: lab_sea, lab_sea.noseaicedyn
536        -> updated
537    
538    checkpoint65i (2015/01/23)
539    o model/src:
540      - change units of frictionHeating field from W to W/m^2
541      - fix bug in frictional heating from stratospheric drag in
542        S/R ATM_PHYS_TENDENCY_APPLY_V
543      - with synchronous time-stepping: move resetting to zero of frictionHeating
544        field from load_fields_driver.F to thermodynamics.F ;
545      - add diagnostics for frictional heating.
546    o model/src & gmredi K3D:
547      - add frictionHeating field to pickup-files (for synchronous time-stepping)
548      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
549      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
550        and name in pickup file).
551      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
552    o model/src:
553      - move (from ini_forcing.F) initialisation of all arrays in header file
554        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
555        (since Nov 2012) with option selectAddFluid=1.
556    o pkg/shelfice:
557      - change units (+ document) of newly added field "shelfIceMassDynTendency"
558      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
559    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
560    o pkg/seaice: two new runtime parameters:
561      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
562        long overdue
563      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
564        parameterization of tensil stress for fast ice (does not do anything yet)
565    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
566        for LSR: move checking overlaps out of JFNK-if-block
567    o pkg/atm_phys:
568      - move copy of grid and dynamical fields out of atm_phys_driver.F into
569        new S/R ATM_PHYS_DYN2PHYS.
570      - fix level height for Linear Free-Surf case (to be consistent with
571        fixed-in-time pressure levels).
572    o pkg/mom_common (bottomdrag):
573      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
574        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
575        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
576    o pkg/shelfice (u/v_drag):
577      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
578      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
579        (now similar to shelfice_u_drag.F)
580      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
581        from mom_vecinv.F (similar to mom_fluxform calls).
582    o pkg/mom_common (bottomdrag):
583      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
584      - add options for alternative discretisation of velocity norm in quadratic
585        bottom drag: averaging of grid-cell-center KE to U.point and V.point
586        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
587        improves when averaging only the other component (e.g. vVel for U bottom
588        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
589      - add options (bottomVisc_pCell) to account for partial-cell in bottom
590        friction (no-slip BC) thus getting the true distance from the bottom;
591        off by default since this also reduces model stability (explicit bottom
592        friction). Changes produce different machine truncation with linear-drag
593        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
594        front_relax (bvp & mxl, 10 & 11 digits).
595    o model/src & mom pkgs:
596      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
597        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
598      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
599        just copy level Nr value to level Nr+1.
600    o doc:
601      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
602    o pkg/streamice:
603      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
604        SHELFICE.h: move array shelficemass to init_varia, initialise
605        from array shelficemassinit, which is set in init_fixed and
606        has option to be set from file; introduce array
607        shelficeMassDynTend array, set thru file in init_fixed
608      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
609        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
610        pkg/streamice
611      - shelfice_thermodynamics.F: call shelfice_step_icemass if
612        SHELFICEMassStepping = .true.
613      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
614    
615    checkpoint65h (2014/12/17)
616    o verification/global_ocean.90x40x15, global_ocean_ebm:
617      - update to generic controls.
618    o pkg/ctrl:
619      - ctrl_map_ini_genarr.F: test for igen>0
620      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
621      - move gentim2d part of ctrl_map_ini_genarr.F to
622        new separate routine : ctrl_map_ini_gentim2d.F
623      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
624        add time variable weights and cyclic controls (time mean,
625        seasonal cycle, etc) capabilities to gentim2d
626    o pkg/ecco:
627      - move reading of error, conversion to weights from
628        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
629    o global_oce_llc90, cs32:
630      - activte sbo.
631      - CTRL_SIZE.h : add maxCtrlProc.
632      - activate the new genctrl capabilities.
633      - update following reorganization of global_oce_input_fields.tar.gz  
634    o pkg/ctrl/ctrl_ad_diff.list:
635      - add missing ctrl_init_rec.f
636    o tools/OAD_support/keepOriginal:
637      - add ctrl_init_rec.F
638    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
639      - avoid recomputations of xx_gentim2d_dummy.
640    o momentum diagnostics:
641      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
642        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
643    o pkg/seaice/seaice_lsr.F:
644      - fix computation of BU/BV, make sure they are non-zero, only necessary
645        for cubed sphere exchanges and SEAICE_OLx/y>0.
646        This makes calling s/r fill_cs_corner_rl obsolete (removed).
647    o verification/global_ocean.cs32x15/input.seaice
648      - add test for strong implicit coupling and restricted addtive Schwarz
649        methods for LSR
650      - update results/output.seaice.txt
651    o verification/tutorial_global_oce_biogeo:
652      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
653        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
654        update output_adm,_oadm,_tlm.txt
655    o pkg/dic:
656      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
657      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
658        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
659    o verification/tutorial_global_oce_biogeo:
660      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
661        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
662        update output_adm,_oadm,_tlm.txt
663    o eesupp/src:
664      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
665        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
666    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
667      LSR (following Hutchings et al. 2004)
668      - introduce zetaZ as a global variable (requires adjustments in
669        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
670        in seaice_calc_viscosities.F
671      - new flag SEAICEuseStrImpCpl (default off)
672      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
673        momentum equations
674      - JFNK-solver (preconditioner) adjusted to allow using this method
675        (where it does not have any positive effect)
676    o pkg/seaice
677      - add overlap for restrictive additive Schwartz method also to LSR, but
678        turn it off by default (because it only seems to work for non-cubed
679        sphere/llc topologies)
680    o pkg/autodiff
681      - add extra exchanges in addummy_in_steppging also for mnc output
682    o pkg/seaice:
683      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
684        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
685    o pkg/obcs:
686      - add option to specify domain-connected piece Id along OB though files
687        (for now, only used to diagnose PhiVel; default =1 -> global correction)
688      - modify obcs_diag_balance.F to process each connected-part separately;
689        exclude OB where Id = 0 but keep the full divergence there (-> constant
690        Psi along this portion of OB and all inflow derived from grad(Phi))
691      - add example of OB-conect files in verification/so_box_biogeo/input.
692    o pkg/diagnostics:
693      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
694      a) use non zero matrix element across OB and solve for Phi 1 grid point
695         outside OB (i.e, where tracer OBCS are applied).
696      b) global imbalance of inFlow/outFlow across OB: instead of modifying
697         velocity across OB, spread it uniformly along the OB in the RHS.
698    
699    checkpoint65g (2014/11/19)
700    o pkg/diagnostcis:
701      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
702    o pkg/my82,pp81,kl10:
703      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
704        field diffKr as background diffusivity to set minimum diffusivity value.
705    o pkg/seaice:
706      - add new parameter SEAICEuseEVPrev (for revisited EVP by
707        Bouillon et al 2013)
708      - add SEAICE_evpAlpha/Beta to namelist
709      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
710        involve trivial re-ordering of divisions/multiplications that should not
711        have any effects, but ... they do change the results of lab_sea.hb87 so
712        that only 2 digits of agreement remain, in line with the general
713        instability/fragility of the evp-code. For now, I do not care and just
714        update the verification experiment
715    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
716      - remove xx_genarr2d_numsmooth etc
717      - use xx_genarr2d_preproc etc instead
718      - carry out smooth_correl2D at initialization stage rather than during
719        time stepping.
720      - get smoothOpNb from xx_gentim2d_preproc
721    o global_oce_cs32 :
722      - add test of generic ecco capabilities.
723    o pkg/exf/exf_getsurfacefluxes.F :
724      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
725    o pkg/ctrl,ecco :
726      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
727        is defined.
728    o pkg/seaice: add diagnostics for Delta (deformation parameter)
729    o model/src:
730      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
731        diffusivity (background) is specified but ignored.
732    o verification:
733      - in testreport, convert hostname to lower case for default output dir name
734    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
735    o pkg/dic: add modifications from Hajoon:
736      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
737      - light attenuation: add self-shading effect by climatological Chlorophyll
738        (read from file).
739    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
740        compiles when SEAICE_ALLOW_DYNAMICS is undefined
741    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
742        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
743        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
744        approach where CPP_OPTIONS.h includes an omnipotent
745        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
746    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
747        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
748    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
749        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
750        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
751    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
752      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
753      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
754      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
755      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
756    o pkg/ctrl,ecco,exf :
757      - remove variables associated with NON-generic costs,
758        unless ECCO_CTRL_DEPRECATED is defined.
759      - remove NON-generic NON-obcs controls,
760        unless ECCO_CTRL_DEPRECATED is defined.
761    o pkg/ctrl : added ctrl_local_params.h
762    o pkg/ecco : added ecco_local_params.h
763    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
764        experiments, which will progressively be removed once the
765        experiments are revised to use only generic controls/costs.
766    
767    checkpoint65f (2014/10/13)
768    o pkg/ctrl, ecco, seaice : minor changes in headers
769    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
770        cost function and control capabilities added since checkpoint65c.
771    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
772    o pkg/ecco: increase modularity and improve logic
773      - ecco_toolbox.F (new) : basic operations that are often used,
774        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
775        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
776      - cost_gencal.F (new) : determine filnames and records.
777      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
778      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
779        and exploit the above functions leading to more compact code.
780      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
781      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
782        using_ers, using_gfo, using_mdt is now only defined within gencost)
783    o pkg/ecco: extend generic cost capabilities
784      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
785        capabilities via gencost_preproc (+ _c,_i,_r related params),
786        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
787        gencost_outputlevel arguments to cost_generic
788      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
789        and active_read, making room for gencost_preproc to take effect.
790        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
791      - pkg/ecco/cost_generic.F :
792        compute and store misfit maks*(model-data) in localdif that is
793        then used in cost and for output, output misfit if outlev.GT.0
794      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
795        rather gencost_barfile for deciding whether to write barfile
796      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
797      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
798        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
799      - pkg/ecco/ecco_summary.F : report gencost variables
800      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
801    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
802    o pkg/ecco: internal re-organization
803      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
804        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
805        mv relevant variables definition from ecco_cost.h to ecco.h,
806        make sure gencost routines only include ecco.h)
807      - throughout : add missing CCP switches, rm unused variables,
808        and rm un-necessary CPP switches
809      - throughout gencost routines : replace modelstartdate with
810        gencost_startdate when needed
811      - cost_bp_read.F : use arguments, instead of common blocs
812        so that it can be used also by (new) cost_gencost_bpv4.F
813      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
814      - ecco_phys.F : compute etanFull
815      - ecco_readparms.F : rename using_topex as using_tpj, add
816        bpv4-grace to gencost list, initialize added parameters
817      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
818    
819    checkpoint65e (2014/09/28)
820    o pkg/obcs:
821      - replaced the just-added CPP options with run-time variables
822        (see pkg/obcs/OBCS_PARAMS.h for details)
823    o pkg/obcs:
824      - add additional CPP options for sponge boundary layers
825        (see pkg/obcs/OBCS_OPTIONS.h for details)
826    o pkg/atm_phys:
827      - implement simple (obliquity only, assuming circular planet orbit)
828        seasonal cycle for incoming insolation ; used when run-time parameter
829        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
830    o pkg/exf, pkg/ecco, pkg/ctrl:
831      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
832      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
833      - implement gentim2d for xx_tauu, xx_tauv
834    o pkg/ctrl, pkg/ecco :
835      - fix and complement the generic controls implementation
836    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
837        pkg/shelfice/shelfice_thermodynamics.F,
838        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
839        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
840      - add weight in CTRL_GET_GEN calls
841    o pkg/ctrl :
842      - ctrl_get_gen.F : add weight as input parameter, and apply
843        it directly rather than using smooth_correl2Dw (to be retired).
844      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
845    o pkg/ctrl :
846      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
847        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
848      - re-activate ctrl_summary (call in ctrl_init.F)
849    o pkg/ctrl/ctrl_cost_gen.F :
850      - fix CCP brackets, remove un-necessary myiter, mytime

854      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
855      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
856    
857    checkpoint65d (2014/09/15)
858    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
859      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
860        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
861    o pkg/ctrl/ctrl_map_ini_genarr.F :
862      - remove compilation failure
863      - replace hard coded example
864      - use ctrl_map_ini_gen2D, 3D
865    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
866      - on/off switch based upon xx_genarr2d_weight,3d
867    o src/packages_init_variables.F :
868      - regroup pkg/estimation calls

876      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
877    o ctrl/ctrl_map_ini.F :
878      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
879        (moved to ctrl_init_variables)
880    o ctrl/ctrl_map_ini_ecco.F :
881      - remove ECCO_PHYS (mv to ecco_init_varia)
882      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
883    o ecco/ecco_ad_diff.list :
884      - add ecco_init_varia.f
885    o ecco/ecco_init_varia.F
886      - new routine
887    o pkg/streamice:
888      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
889        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
890      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
891    o pkg/generic_advdiff:
892      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
893    o pkg/exf:
894      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
895         xxg_precip capability
896      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
897    o pkg/ctrl:
898      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
899    o model/src/load_fields_driver.F :
900      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
901        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
902    o OpenAD verification experiments:
903      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
904        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
905        for now, only in pkgs used in OpenAD verification experiments.
906      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
907        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
908        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
909        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
910    o OpenAD verification tests:
911      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
912      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
913        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
914      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
915        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
916    o model/src & generic_advdiff:
917      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
918        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
919        dynamics requires valid tracer forcing only over tile interior but, for
920        some diagnostics, may need to extend it over 1 point in tile halo region.
921      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
922        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
923        setting in temp/salt/ptracer_integrate.F
924    o pkg/dic:
925      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
926        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
927        in gchem_forcing_sep.F
928    o pkg/autodiff & obcs:
929      - add storage of current OB values for U & V (was already done for T & S).
930    
931    checkpoint65c (2014/08/30)
932    o pkg/dic:
933      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
934        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
935        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
936    o verification:
937      - new experiment testing OBCS and DIC pkgs, using params & output from
938        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
939        passage: take OBCS from the last year of a 2 yrs simulation and initial
940        conditions from t=1.yr while keeping the same forcing.
941    o model/src:
942      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
943        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
944    o pkg/diagnostics (Stats-Diags):
945      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
946        a) refine region where stats are computed, excluding where arrhFac=0 ;
947        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
948        c) extend regional stats over the region edges (for U or V pt location).
949    o pkg/gchem:
950      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
951        pkg/dic is currently changing/updating ptracers values beyond the OB).
952    o verification (hs94):
953      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
954        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
955        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
956        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
957    o pkg/ptracers:
958      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
959        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
960      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
961        with AB-2 code (so that it get tested).
962    o model/src:
963      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
964        with AB-2 code (previously only available with AB-3 code).
965        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
966        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
967        there, by calling CYCLE_AB_TRACER).
968    o pkg/generic_advdiff:
969      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
970        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
971        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
972        S/R temp/salt/ptracers_integrate.F
973    o model/src & pkg/ptracers:
974      - remove common block variables gT,gS (in DYNVARS.h), except when
975         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
976      - remove common block variable gPtr.
977    o model/src & pkgs:
978      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
979         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
980         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
981         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
982      + change accordingly all calling S/R.
983      - use local temperature/salinity/ptracer tendency array (without bi,bj)
984        in S/R temp/salt/ptracers_integrate.F
985    o pkg/seaice:
986      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
987        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
988      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
989        in seaice_lsr
990      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
991        in s/r seaice_lsr_calc_coeffs
992    o pkg/mdsio:
993      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
994        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
995        too long (e.g., > MAX_LEN_FNAM/2 )
996    
997    checkpoint65b (2014/08/12)
998    o pkg/matrix:
999      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1000    o model/src:
1001      - fix initialisation of geothermalFile; compile geothermal-flux code in
1002        natl_box verification experiment.
1003    o model/src & pkg/down_slope:
1004      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1005      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1006        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1007        results at machine truncation level: update output of experiments
1008        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1009    o pkg/diagnostics (Stats-Diags):
1010      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1011        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1012        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1013        times (but Min,Max and StD are still wrong).
1014    o model/src:
1015      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1016        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1017    o model/src:
1018      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1019        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1020        arrays are already updated while adjustments (filters, conv.adjustment) are
1021        still applied later, in S/R TRACERS_CORRECTION_STEP.
1022    o model/src:
1023      - store in common bloc array "rhoInSitu" the virtual potential temperature
1024        anomaly that is used to compute geopotential: this make the atmos code
1025        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1026    o pkg/seaice/seaice_lsr.F
1027      - rename integer variable ilcall to ipass (that's what it is called
1028        in the residual diagnostics
1029      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1030        default) for improved non-linear convergence of the first few steps
1031      - adjust a few comments and add new ones to explain some of the store
1032        directives
1033    o pkg/generic_advdiff (& ptracers):
1034      - re-work the code to check for valid advection scheme and for minimum
1035        size of overlap (now stored in local common bloc in gad_advscheme.F)
1036    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1037      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1038      - add an auxilliary variable "bet" and fix store directives and keys in
1039        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1040        less exact gradients in my tests); but there are still
1041        recomputation warning (although gradients are sort of OK), when
1042        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1043        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1044      - update verification experiments lab_sea.
1045      - change some comments in S/R seaice_calc_viscosities
1046    o model/src:
1047      - if staggerTimeStep=T, always apply exchange to velocity field in
1048        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1049        (independent of using multi-dim advection or not); no effect on FWD run
1050        but affects AD results (at machine truncation level): update output of
1051        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1052        and isomip (oad: 12.d).
1053    o pkg/generic_advdiff:
1054      - stop if doAB_onGtGs is set to FALSE but ignored
1055      - refine warning related to stability of tracer time-stepping
1056        regarding internal wave dynamics.
1057      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1058        on staggerTimeStep & implicitIntGravWave (will now get a warning
1059        if potentially unstable).
1060    o pkg/kl10:
1061      - add new pkg "kl10" for mixing due to internal wave breaking, from
1062        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1063        (contribution from Jody Klymak), tested in verification experiment
1064        verification/internal_wave/input.kl10/
1065    o isomip experiment:
1066      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1067        (input.htd) and update the output.
1068    o cd_code experiments:
1069      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1070        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1071        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1072        update the corresponding output.
1073    o pkg/seaice:
1074      - reduce the number of include files and store directives in
1075        S/R seaice_lsr_tridiagu/v
1076      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1077        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1078        get rid off one store directive (a TAF bug?)
1079      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1080        S/R seaice_lsr_tridiagv to change the loop range for consistency
1081      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1082      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1083        S/R seaice_lsr_tridiagu/v (requires update of
1084        offline_exf_seaice/input.dyn_jfnk)
1085    
1086    checkpoint65a (2014/07/27)
1087    o model/src:
1088      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1089        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1090        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1091        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1092    o model/src:
1093      - collect momentum forcing tendency into local 2-D array (passed as argument
1094        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1095        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1096        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1097      - collect T & S forcing tendency into local 2-D array (passed as argument to
1098        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1099        affects results at machine truncation level (e.g., ocean: if using
1100        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1101        correction due to vertical advection).
1102      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1103        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1104        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1105        obcs_ctrl (ad & fwd grd @ 12 & 7).
1106    o pkg/ptracers & diagnostics:
1107      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1108        title (to avoid some unexpected truncation); sort out ptracers diags units.
1109      - collect ptracer forcing tendency into local 2-D array (passed as argument
1110        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1111    
1112    checkpoint65 (2014/07/18)
1113    o pkg/fizhi:
1114      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1115        affects results at machine truncation level. Update output of experiments
1116        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1117    o pkg/seaice: more clean up
1118      - rename TAF common block tapes to be more consistent and remove
1119        unnecessary duplicates
1120      - add store directives to remove more recomputations, but use smaller
1121        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1122        The idea behind this flag is to reduce the memory footprint when the
1123        adjoint of the LSR is not required. As of now, defining the flag
1124        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1125        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1126        For experiment offline_exf_seaice, this means on a linux box with gfortran
1127        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1128        this experiment):
1129        > size mitgcmuv_ad
1130        text    data        bss     dec        hex
1131        5100659 1216  220458952  225560827  d71c8fb
1132        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1133        but only a moderate increase of 36% for global_ocean.cs32x15:
1134        text    data        bss     dec        hex
1135        6695027 1648 1014578664 1021275339 3cdf6ccb
1136        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1137      - note: there are still recomputations in global_ocean.cs32x15 and
1138        offline_exf_seaice and the gradient agreement changes (gets a
1139        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1140      - in general, the AD gradients still are wrong
1141    o OpenAD
1142      - clean up code_oad/ directories somewhat by moving files
1143        dontCompile, dontTransform, keepOriginal to OAD_support/
1144    o model/src:
1145      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1146        (not currently tested): add dissipation terms before NLFS rescaling of
1147        tendencies (previously done after).
1148    o pkg/diagnostics:
1149      - write stats-diags in ascii file with more digits (same as in monitor).
1150    o pkg/down_slope:
1151      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1152        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1153    o model/src:
1154      - new file "apply_forcing.F" containing all the code previously in
1155        external_forcing.F, but with new argument list: pass, as new argument,
1156        the current level tendency array to update (instead of a direct update
1157        of the common bloc array). Change the corresponding calls.
1158      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1159        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1160    o pkg/seaice/seaice_lsr, a little bit of clean up
1161      - rearrange some code blocks, so that now all calculations for
1162        setting up the right-hand-sides done within one single block
1163        (I find that easier to read and understand)
1164      - rearrange freedrift-code to reduce the number of ifdefs
1165      - adjust some indentations and comments
1166    
1167    checkpoint64z (2014/07/10)
1168    o model/src and several pkgs:
1169      - change argument list of all S/R called from external_forcing.F and
1170        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1171        to pass, as argument, the current level tendency array to update
1172        (instead of a direct update of the common bloc array).
1173      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1174      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1175    o pkg/seaice/seaice_lsr.F
1176      - always initialize local arrays in seaice_lsr_tridiagu/v
1177      - add more local tapes to seaice_lsr_tridiagu/v
1178      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1179        keep it in bi/bj loop; this seems to be essential
1180      - gradients are still wrong but only by 4-7 orders of magnitude
1181        instead of 15 orders of magnitude, lab_sea improves a little
1182    o pkg/seaice
1183      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1184        generates unnecessary code in seaice_lsr_ad
1185      - add more store directives in seaice_lsr to avoid unnecessary code
1186        in seaice_lsr_ad
1187      - exclude some residual computations in seaice_lsr when
1188        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1189        in seaice_lsr_ad
1190      - add more storing, a new tape (model/src/the_main_loop.F) and
1191        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1192        and klockey should be checked by a specialist)
1193      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1194        and update lab_sea after previous changes in pkg/seaice below
1195    o pkg/autodiff:
1196      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1197        viscFacInAd : run time parameters allowing for adjoint switches
1198        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1199    o pkg/ecco:
1200      - introduce cost_gencost_boxmean.F that computes a box mean
1201        temperature (for use in adjoint sensitivity studies).
1202    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1203    o pkg/mom_common/mom_calc_visc.F:
1204      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1205    o pkg/seaice/seaice_summary.F:
1206      - statement for SEAICEadjMODE now in autodiff_readparms.F
1207    o pkg/seaice:
1208      - remove some store directives and add new ones in an effort to get
1209        finally rid off the recomputation warnings. This is successful
1210        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1211        defined (i.e. no extensive recomputation warnings left), but there
1212        are still too many recomputations on the solver iteration level
1213      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1214      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1215        SEAICE_SIZE.h
1216      - add a store directive in S/R seaice_calc_viscosities
1217    o pkg/seaice (ITD code):
1218      - fix definition of Hlimit for multi-threaded case
1219      - use double precision arithmetic to compute Hlimit: this affects results;
1220        update output of experiment seaice_itd.
1221    o replace content of verification/seaice_itd
1222      - instead of a 1D column use the configuration of offline_exf_seaice
1223        to test the ice thickness distribution code with ridging
1224      - this is a first shot at this experiment
1225      - change of some defaults of ridging parameters SEAICEhStar (from
1226        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1227        and lot of new comments.
1228    
1229    checkpoint64y (2014/06/20)
1230    o pkg/seaice/seaice_reg_ridge.F:
1231      - modify the regularization of very small volumes of ice; only check
1232        total volume HEFF, and do not apply correction to individual ice
1233        classes because that leads to funny patterns in the heat and fw-fluxes
1234        into the ocean. Adjust seaice_itd/results/output.txt
1235      - replace nITD by SEAICE_multDim in loop-ranges
1236    o pkg/exf:
1237      - add code to process the case field period = -12. with UV interpolation.
1238      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1239        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1240    o verification/global_with_exf:
1241      - switch all fields period to -12. (was previously untested) in input/data.exf
1242        (but keep secondary test ".yearly" unchanged); update the reference output.
1243    o pkg/cal:
1244      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1245    o pkg/exf:
1246      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1247        to replace logical switch "exf_verbose"
1248      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1249    o pkg/sbo:
1250      - update from Katherine Quinn: evaluate mass directly from density and SSH
1251        (budget using Finite Volume method) instead of from bottom pressure.
1252      - allow testreport to collect few selected SBO output ; tested in exp.
1253        global_ocean.90x40x15 (after updating the results, to include SBO output).
1254      - fix some multi-threading issues (in output part).
1255    o model/src & most packages:
1256      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1257      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1258        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1259        "data.{pkg}" exist ; and leave the S/R (return) just after.
1260      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1261        + call LAND_READPARMS from packages_readparms.F
1262    o pkg/seaice:
1263      - remove code that resets useThSice in S/R seaice_readparms and
1264        replace it by a warning in S/R seaice_check
1265      - remove parameter MULTDIM, replace with nITD and runtime
1266        parameter SEAICE_multDim (still hard-wired to nITD if
1267        SEAICE_ITD is defined)
1268    
1269    checkpoint64x (2014/05/24)
1270    o verification/lab_sea:
1271      - update adjoint and TLM output following changes to pkg/salt_plume
1272      - un-do the update after putting back local recip_Cp in few places.
1273    o pkg/salt_plume: modifications by An Nguyen:
1274      - add capability to do brine rejection (salt-plume) as function of
1275        volume+tracers (instead of only salinity tracer).
1276      - conserve volume by exchanging volume from each kLev to above to
1277        accommodate in-coming brine volume
1278      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1279      - switch KPP surf buoyancy due to brine forcing to 3-d
1280        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1281      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1282      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1283        in East/West Arctic.
1284    o pkg/sbo:
1285      - incorporate modifications from Katherine Quinn to enable the use of sbo
1286        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1287        output for future testreport verification (unfinished).
1288    o pkg/atm_phys:
1289      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1290        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1291        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1292    o pkg/seaice
1293      seaice_calc_ice_strength.F: modify expression to avoid divisions
1294        (affects truncation)
1295      seaice_do_ridging.F: clean up the insectarium
1296      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1297      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1298      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1299      - add some debugging information and error messages (warnings)
1300    o model/src: modifications relatd to atmosphere p*:
1301      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1302      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1303        of vertical profile tRef in geopotential background and anomaly.
1304      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1305        and pkg/atm_phys.
1306      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1307        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1308    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1309    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1310        not used right now, but can be used in BGC packages to fix conservation.
1311    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1312        other packages too.
1313    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1314        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1315    o model/src:
1316      - since we have several heat capacity (even in model/src), define "recip_Cp"
1317        as local variable (no longer in common block) to avoid any confusion.
1318      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1319    o pkg/exf:
1320      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1321        air density as function of air Temp, Humidity and atm pressure.
1322    
1323    checkpoint64w (2014/05/02)
1324    o verification:
1325      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1326        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1327        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1328        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1329        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1330    o model/src: for atmosphere in p* coords:
1331      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1332      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1333        but not yet activated.
1334    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1335      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1336      - this changes the results (but not for any verification experiment, because
1337        none tests this), but avoids having an extra field in the restart files
1338    o pkg/seaice: remove global variable TICE (not needed)
1339      - replace by TICES or local variable where necessary (cost_seaice_test,
1340        seaice_diagnostics_state)
1341      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1342      - use specific read/write routines for reading and writing individual leves
1343        of a multilevel field
1344    o pkg/ctrl & model/inc:
1345      - move additional anomaly fields of control vars (related to options:
1346         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1347        from DYNVARS.h into new header file: CTRL_FIELDS.h
1348    o pkg/seaice: some small modifications to the ridging code
1349      - make fw2ObyRidge a global variable and add the freshwater flux to
1350        seaice_growth
1351      - pass actual thickness from seaice_prepare_ridging, so that it is
1352        computed only in one place and compute it in the same way as in
1353        seaice_growth
1354      - initialise more fields in seaice_do_ridging that where cause floating
1355        point exceptions over land
1356    o pkg/seaice: preparations for ridging code and first real ridging code
1357      - move most of "PART 1" of S/R seaice_growth into a new and separate
1358        S/R seaice_reg_ridge that will both regularize the state variable after
1359        advection call the actual ridging routine;
1360      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1361        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1362      - remove ridging code from seaice_advdiff
1363      - clean up remaining part 1 of seaice_growth in an attempt to make it
1364        more readable (this is probably subjective)
1365      - call seaice_itd_redist once in the initialisation phase to have the initial
1366        conditions in the correct category
1367      - finally: add new ridging routine for ITD code
1368    
1369    checkpoint64v (2014/04/11)
1370    o pkg/ecco:
1371      - add runtime parameters mdt[start,end]date[1,2]
1372      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1373    o pkg/seaice:
1374      - make deltaC a global variable, so that it can be used in ridging code
1375      - first step towards ridging: introduce new routines that compute
1376        ice strength based on ridging parameters
1377      - add diagnostic for HSNOWITD
1378      - add opnWtrFrac as a global variable (required for ridging scheme)
1379    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1380      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1381        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1382    o verification/hs94.1x64x5:
1383      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1384      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1385    o autodiff:
1386      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1387        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1388        For now, only in pkgs used in verification/hs94.1x64x5.
1389      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1390        which are specific to TAF/TAMC).
1391      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1392        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1393        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1394      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1395        building mitgcmuv_ad (make adAll).
1396    o pkg/ecco:
1397      - cost_gencost_seaicev4.F:
1398         reformulate proxy cost as function of sst and local param SEAICE_freeze
1399         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1400      - add stop statement if old names siv4-[sst,vol] are used
1401      - add snapshots + cost reports for atmospheric longwave
1402      - remove factor 0.1 in front of wtau[u,v]
1403      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1404         ALLOW_TMI_SST_COST_CONTRIBUTION
1405    o pkg/atm_phys:
1406      - add some diagnostics for Short-wave and for convection S/R.
1407    o pkg/seaice/seaice_growth:
1408      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1409        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1410      - rearrange loop order for better vector code in the same code block
1411      - rewrite the floeDiameter formula to have fewer divisions
1412      -  (miraculously) none of this changes the results of seaice_itd
1413    o pkg/smooth:
1414      - move param smooth2Ddiffnbt to pkg/ecco
1415    o pkg/salt_plume:
1416      - salt_plume_frac.F:
1417         clean up local param names
1418         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1419    o pkg/rw:
1420      - add RS version of S/R READ_MFLDS_LEV.
1421    o pkg/streamice:
1422      - fix the restart test by writing/reading pickup_streamice files.
1423    o pkg/seaice:
1424      - refine checks for jfnk-related parameters
1425      - comment out if statement with SEAICEuseIMEX parameter as long as there
1426        is no IMEX code to avoid confusion and surprises
1427    
1428    checkpoint64u (2014/03/07)
1429    o verification/MLAdjust:
1430      - rename secondary test suffix:
1431         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1432         0.leithD -> AhFlxF  + switch to flux-form
1433         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1434         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1435    o pkg/mom_vecinv:
1436      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1437        to be before mom_calc_visc.F)
1438      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1439      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1440        this is simpler for the adjoint and for diagnostics.
1441    o model/src + pkg/momentum:
1442      - add input files for  2-D additional Western and Southern cell-edge wall
1443         (e.g., to add "thin-wall" where it is =1).
1444      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1445        using 2nd hFacZ that is computed from initial (fix domain) hFac
1446      - known limitations of thin wall implementation: not yet coded for sigma
1447        coords; not working with CD-scheme neither.
1448    o pkg/seaice:
1449      - rename recently introduced parameters from (wrong name) AB to
1450        BDF (backward difference time discretisation)
1451      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1452    o tools/adjoint_options:
1453      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1454    
1455    checkpoint64t (2014/02/01)
1456    o pkg/ecco
1457      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1458        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1459      - replace hard-coded record number and period which only work for monthly
1460        with read-in runtime param that works for other periods (month,day,year)
1461    o pkg/thsice
1462      - corrected store directive fixes thsice adjoint gradient checks
1463    o genmake2 & testreport:
1464      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1465        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1466        Update testreport accordingly. No need to set "export OPENAD=true"
1467        in adjoint_options/adjoint_oad anymore (will be removed later).
1468    o pkg/shelfice:
1469      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1470        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1471        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1472    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1473      - Changes to make GENARR more modular (i.e. invisible if not used)
1474    o model/src/temp_integrate.F and salt_integrate.F
1475      - re-include store directives that were removed on Dec 27th.
1476    o model/src/external_forcing_surf.F
1477      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1478        seaice_model in the adjoint that is problematic when seaice_model is
1479        turned off in the adjoint. The resolved issue dated back to July when
1480        EXTERNAL_FORCING_SURF call was moved.
1481        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1482    o pkg/exf/exf_check.F
1483      - fix a small bug again (originally found by Wentao Liu, now found again)
1484      - streamline error output
1485    o pkg/streamice and aim_v23:
1486      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1487        Apple's /usr/bin/cpp knows what to do:
1488        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1489        Target: x86_64-apple-darwin13.0.0
1490    
1491    checkpoint64s (2014/01/05)
1492    o tools/adjoint_options:
1493      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1494        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1495    o model/src:
1496      - remove some unnecessary TAF storage directives in forward_step.F and
1497        in dynamics.F (note: not always removed by TAF, e.g., double storage
1498        of kappaRU,kappaRV in former version of dynamics.F).
1499    o model/src & pkg/ptracers:
1500      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1501        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1502        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1503      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1504      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1505      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1506    o useSingleCpuInput separates single-CPU input from single-CPU output;
1507        for now only implemented for in exf_interp_read.F
1508    o verification/advect_xy:
1509      - fix missing EXCH call in local version of ini_salt.F and update output.
1510    o momentum diagnostics:
1511      - fix which deltaT is used in Total-Tendency diagnostics.
1512      - fix typo in diagnostics for momentum tendency from AB.
1513    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1514        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1515    
1516    checkpoint64r (2013/12/08)
1517    o verification/*/results:
1518      - Update reference output of experiments that were passing with just 13 digits
1519         (make it easier to detect future changes in results)
1520    o model/src & pkg/ptracers:
1521      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1522        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1523        to inside ptracers_integrate.F ; remove ptracers_advection.F
1524    o coupling interface pkgs:
1525        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1526      - change the config check to test the agreement of Ocean Depth
1527        with ATM land/sea mask (instead of ATM orography);
1528      - send to coupler the number of coupler time-steps to do for this run:
1529        this allows to check for consistency and don't need anymore to be
1530        specified in parameter file "data";
1531      in coupler:
1532      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1533      - improve report to log-file of config setting (pass log-file unit to few S/R)
1534    o pkg/compon_communic:
1535      - add coupling send/receive for non-tiled integer vector;
1536      - add S/R to check and stop if any proc has an error (similar to
1537        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1538    o pkg/exch2:
1539      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1540        through list of all tiles my proc owns.
1541    o model/src:
1542      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1543        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1544        calling S/R); this affects AD results at machine truncation level:
1545        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1546        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1547    o tools/build_options:
1548      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1549    o coupling interface pkgs:
1550        [compon_communic, atm_compon_interf & ocn_compon_interf]
1551      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1552        to each S/R that needs it; remove un-used variables.
1553      - change component tile registration (cpl_register.F in both compon_interf
1554        and mitcomponent_tile_register.F) to pass the full list of tiles
1555        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1556      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1557        towards coupler global array (unless W2_useE2ioLayOut=F):
1558         a) can now use different tiling between atm & ocn comp.
1559         b) no needs to modify the run-Off map when changing tiling (was needed
1560            even if using the same tiling between atm & ocn).
1561         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1562            full land tiles); not yet tested.
1563      - check for valid mapping from comp. tile to coupler global array
1564      - improve report of tile registration results to log file.
1565    o pkg/exch2:
1566      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1567        tile-registration (CPL_REGISTER);
1568      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1569        store the local bi,bj indices of each tile;
1570      - also print bi,bj in local report to log file;
1571      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1572        Jun 2009 modif of pkg/exch2).
1573    o testing on baudelaire:
1574      - run 2 tests at a time: no significant slow down (since enough cpu) and
1575        get the full set of test done earlier
1576      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1577    o model/src/thermodynamics.F and routines called from it:
1578      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1579        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1580        velocity (outp) by adding bolus velocity.
1581      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1582        mass transport from velocity + lateral grid cell area
1583      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1584      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1585     in thermodynamics.F
1586      - remove k from thermodynamics.F and move it to temp_integrate.F
1587        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1588        loop).
1589      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1590        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1591        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1592        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1593      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1594        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1595        tutorial_tracer_adjsens (+ TLM output).
1596    o tools/OAD_support and (verification/*/) code_oad:
1597      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1598        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1599      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1600        version (closer to model/inc/CPP_OPTIONS.h).
1601    o model/src:
1602      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1603        retired list of parameters (routine FREEZE has been replace by surface
1604        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1605    o pkg/gmredi:
1606      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1607        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1608      - update output of FWD experiments: front_relax.bvp,
1609        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1610    
1611    checkpoint64q (2013/11/17)
1612    o verification:
1613      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1614        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1615      - generate new output (growth & melt) for seaice_itd experiment after
1616        updating the input pickup_seaice files (previously wrong).
1617    o pkg/cost:
1618      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1619        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1620        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1621          cannot be applied to var in common block).
1622        o allows to get results independent of tile-per-proc setting (if using
1623          slower GLOBAL_SUM_SEND_RECV option).
1624      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1625        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1626        forward gradients: update output).
1627      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1628        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1629    o pkg/mom_common:
1630      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1631        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1632        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1633        ensure that all field value that are used are set.
1634    o tutorial_deep_convection (smag3d):
1635      - add missing scaling in mom_calc_smag_3d.F;
1636      - set smag3D_coeff in input.smag3d such that results do not change.
1637    o pkg/dic:
1638      - change dic_cost.F to compute cost on each tile first and then apply
1639        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1640        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1641      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1642    o eesupp/src & pkg/mdsio:
1643      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1644        (from pkg/mdsio) since they are no longer used for tape IO.
1645      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1646        (+ keep a copy in pkg/atm_ocn_coupler).
1647    o verification/isomip:
1648      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1649    o tools/build_options:
1650      - optfile linux_amd64_ifort11, fast (no ieee) case:
1651        to get a working restart for all experiments, add "-fp-model source"
1652        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1653    
1654    checkpoint64p (2013/10/20)
1655    o pkg/autodiff:
1656      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1657        criteria, return to simple (default) tape IO format.
1658    o pkg/mdsio (+ eesupp/src):
1659      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1660        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1661      - fix globalFile and singleCpuIO options using simpler global mapping.
1662      - new pairs of scatter/gather vector S/R (one for each type, generated from
1663        template) corresponding to simpler global mapping.
1664      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1665        to globalFile when parameter globalFiles is set to True.
1666      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1667    o pkg/autodiff:
1668      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1669        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1670        missing, just add a STOP if array type do not match.
1671    o pkg/exf:
1672      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1673         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1674         and rename array obsSIce to exf_iceFraction.
1675    o tutorial_deep_convection:
1676      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1677        for now all in this exp. code dir.
1678      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1679        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1680    o eesupp/src:
1681      - added SINGLE_DISK_IO option because reading of parameter files on
1682        very large number of processors did not work with existing set-up
1683    
1684    checkpoint64o (2013/09/25)
1685    o pkg/atm_phys & atm_compon_interf:
1686      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1687    o tools/build_options:
1688      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1689        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1690        remove CPP setting (was identical to genmake2 default).
1691    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1692      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1693      - fixed up the calculation of the eddy stress and how it is added to the
1694        external forcing via taueddy_external_forcing.F
1695      - at the moment, it is very experimental and only works with the variable eddy
1696        diffusivity calculated in gmredi_k3d.F
1697    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1698        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1699    o testreport (& tools/do_tst_2+2):
1700      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1701    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1702      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1703      - add switch (for big setups) to use 'medium' memory-model (but leave it
1704        commented out for now). Note: needed with FC 19 to compile big setups.
1705    o pkg/atm_compon_interf:
1706      - regroup per field origin (model & pkgs) the coupling storage routines
1707         (which accumalate in time each coupling field)
1708      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1709        update accordingly + simplify aim_do_physics.F
1710    
1711    checkpoint64n (2013/08/26)
1712    o pkg/bbl:
1713      - update formulation to reduce dispersion of tracer properties in bbl
1714      - replaced horizontal and vertical transport parameters with velocities
1715      - changes results for verification/global_with_exf.yearly
1716    o verification/halfpipe_streamice:
1717      - change to matrix construction; update both Fwd & AD output.
1718    o verification/tutorial_tracer_adjsens:
1719      - OpenAD test: switch to vector-invariant momentum since fluxform with
1720        rStar causes problems with OpenAD; update output.
1721    o tools:
1722      - genmake2: define a common prefix for all temp-file names ; move them
1723        to local /tmp disk (but would be easy to move them back);
1724      - xmakedepend: apply the same switch for temp-files.
1725    o pkg/offline:
1726      - changes for use with rStar (NLFS): assume that we continue to provide
1727        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1728        output files) and apply r* scaling at each time-step (function of the time
1729        varying Eta field); use normal pickup files (needed for restart with NLFS).
1730    o adjoint with OpenAD:
1731      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1732        package openad.  This package has to be compiled for all runs with OpenAD
1733        instead of specifying code_oad_all as a modification directory.
1734      - link the fortran templates from tools/OAD_support to the build directory
1735        for preprocessing to avoid conflicts between different setups compiled
1736        simultaneously and simplify cleanup.
1737    o pkg/exf:
1738      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1739        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1740    o model/src:
1741      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1742        (similar to do_fields_blocking_exchanges.F).
1743    o tools/genmake2:
1744      - remove TAF output src code just before calling staf (when not doing a fresh
1745        built, will stop if things go wrong with staf).
1746      - fix target "adobj" (left from TAF version-2 transition)
1747    o pkg/diagnostics:
1748      - add a parameter to track the status of pkg/diagnostics activation;
1749        this replace/extend the use of logical param "settingDiags" (to check
1750        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1751        New S/R to print error message and stop when pkgStatus is not right.
1752      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1753    
1754    checkpoint64m (2013/08/13)
1755    o model/inc:
1756      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1757        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1758    o pkg/kpp & aim_v23:
1759      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1760    o pkg/seaice:
1761      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1762        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1763      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1764    o eesupp/src:
1765      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1766        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1767    o switch to TAF version-2:
1768      - add flow directives to "freeze" naming convention for ad-routines that
1769        are used in I/O routines of adjoint state and associated common blocks
1770        that are used in adcommon.h (backward compatible with version-1)
1771      - update all ad-optfiles (in tools/adjoint_options + few local to some
1772        verification exp) to switch to latest TAF version (currently 2.5.5);
1773        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1774        out except for diva).
1775      - the major change with TAF version-2 is that both the differentiated
1776        routines and the forward routines (new) are returned as part of the TAF
1777        output source code. Update genmake2 accordingly.
1778      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1779        with version-2 when compared to TLM or FWD gradient); other experiments
1780        output show minor changes (machine truncation level); update the few AD &
1781        TLM output with 12 matching digits only (some prior to version-2 switch).
1782    
1783    checkpoint64l (2013/08/05)
1784    o model/src:
1785      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1786      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1787        when using TAF but only if using OpenAD.
1788    o pkg/mom_common+fluxform+vecinv:
1789      - always set horiz. viscosity arrays to background value before calling
1790        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1791        only when using variable horiz. viscosity (useVariableVisc=T);
1792      - simplify mom_vecinv.F (only 1 block for momViscosity).
1793    o pkg/mom_common: variable horiz. viscosity in NH code
1794      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1795        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1796      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1797        useBiharmonicVisc & useVariableVisc.
1798      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1799        in calc_gw.F, version 1.27, 2006/06/20):
1800        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1801        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1802      - change background horiz viscosity in vertical momentum (gW) to always be
1803        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
1804        any type of variable viscosity, e.g., viscAh/4Grid)
1805      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
1806        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
1807        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
1808        default viscAh,viscA4 is zero).
1809    o model/src:
1810      - extend length of drC & recip_drC from Nr to Nr+1.
1811    o Divided Adjoint (DIVA) with MPI:
1812      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
1813      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
1814        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
1815    
1816    checkpoint64k (2013/07/23)
1817    o tools/OAD_support:
1818      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
1819        and remove it from genmake2.
1820    o tools/build_options:
1821      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
1822        MPI_HEADER_FILES list (let genmake2 find the missing headers)
1823    o verification/halfpipe_streamice:
1824      - change to driving stress formulation; update both Fwd & AD output.
1825    o tools/genmake2 and Divided Adjoint with MPI:
1826      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
1827      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
1828      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
1829        Makefile, which is set by genmake2, and check which mpi-headers are needed.
1830        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
1831      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
1832    o testreport:
1833      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
1834        perform additional runs (number of additional runs is "add_DIVA_runs" taken
1835        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
1836    o verification/lab_sea (AD test):
1837      - change to test Divided Adjoint Run in this set-up (both standard AD test
1838        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
1839    o pkg atm_ & ocn_compon_interf:
1840      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
1841        staggerTimeStep implementation) and disable (retired) corresponding
1842        parameter.
1843    o pkg/offline:
1844      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
1845      - add S/R OFFLINE_CHECK to print offline parameter summary
1846        and stop if loading a file that is not used;
1847      - enable to calculate GMRedi tensor, KPP mixing and convective index
1848        when the corresponding file(s) is/are not specified (but pkg is used).
1849      - comment out resetting of monitorFreq (to endTime) since it still useful
1850        for monitoring CFL numbers and checking offline fields.
1851    o OpenAD:
1852      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
1853        smaller standard output) and generate new (smaller) output (on baudelaire
1854        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
1855    o model/src:
1856      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
1857        (where external_forcing_adjust was called) and change list of arguments;
1858      - merge external_forcing_adjust.F into external_forcing_surf.F
1859      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
1860        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
1861        previously in file "balance_relax.F", now removed); remove corresponding
1862        arrays in FFIELDS.h.
1863      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
1864        a hack for getting back surfaceForcingS (loaded from file) when using
1865        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
1866      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
1867        (was getting only 11 digits for AD-grad, due to different truncation
1868         error in AD code).
1869    
1870    checkpoint64j (2013/07/04)
1871    o pkg/offline:
1872      - to enable the use of other features with pkg offline (e.g., obcs),
1873        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
1874      - comment out "allowFreezing" (now active) in 2 offline testing exp.
1875  o pkg/exf ALLOW_RUNOFTEMP  o pkg/exf ALLOW_RUNOFTEMP
1876    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
1877    - added RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice    - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
1878    - changes verification/global_ocean.cs32x15/results/output.seaice.txt    - changes verification/global_ocean.cs32x15/results/output.seaice.txt
1879  o pkg/atm_phys:  o pkg/atm_phys:
1880    - 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).
