4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/atm_compon_interf:
8      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
9        pass last value, stored directly before export to CPL ;
10        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
11      - remove atmSLPr from pickup files (no longer needed for restart)
12    
13    checkpoint65s (2016/01/13)
14    o eesupp & genmake2:
15       - first check for Function ETIME and, if it fails, then check for subroutine
16         ETIME and consistent output; use the appropriate version in timers.F
17    o model/src:
18      - to check restart test, add option to apply EXCH to U,V earlier, just before
19        integr_continuity; turned off by default.
20    o pkg/dic:
21      - remove CPP option USE_ATMOSCO2 (not needed)
22    o tools/tst_2+2:
23      - try to ignore difference between +0 and -0 in binary file, causing test
24        to fail for no good reason.
25    o eesupp & genmake2:
26      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
27        but also check (in genmake2) that test runs and returns meaningful results.
28    o coupler pkgs:
29      Finish implementation of optionally-exchanged variable switches (started on
30       Nov 12) with addition of few more exchanged fields, including 2-way exchange
31       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
32       advection in OCN component; this requires sequential coupling.
33      coupler (pkg/atm_ocn_coupler):
34      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
35        routines (useful for debug).
36      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
37         flux, DIC fields) if corresponding switch is ON.
38      - add option to export RunOff to OCN (to use for DIC river input)
39      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
40      components (pkg/atm_ & ocn_compon_interf):
41      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
42        optionally exchanged fields; add a check & stop in cpl_readparms.F.
43        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
44        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
45      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
46        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
47      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
48      - hold in common block coupler optionally-exchanged variable switch
49        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
50      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
51        this is intended to replace the OCN cplFldtave.* output files (not updated
52        to contain new additional exchanged fields).
53    o pkg/dic:
54      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
55    o pkg/thsice:
56      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
57        and writing of thsice pickup files.
58    o pkg/atm_compon_interf:
59      - move all field individual export-call out of cpl_export_import_data.F
60        into new S/R ATM_EXPORT_FIELDS
61    o pkg/atm_compon_interf:
62      - store state variables (for now, only thSIce fields) just before beeing
63        exported (in cpl_export_import_data.F, like on ocean side) instead of from
64        atm_store_my_data.F like all exported fluxes.
65      - new version of pickup_cpl: write field names into meta file and read meta
66        file to find field postion in pickup. Also only write/read fields meeded for
67        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
68    o pkg/dic:
69      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
70    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
71        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
72        value can be from domain [0,1] to average between the two methods
73    o pkg/atm_phys:
74      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
75        hold fixed in time).
76    
77    checkpoint65r (2015/12/21)
78    o pkg/seaice:
79        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
80        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
81    o pkg/seaice:
82      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
83        when SEAICEscaleSurfStress=.TRUE.,
84      - apply areaW and areaS in S/R seaice_calc_lhs
85    o pkg/atm_phys:
86      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
87        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
88        for individual contribution (convection, LSC cond, radiation)
89      - add Ruth Geen etal, GRL 2016, radiation optionis (see paper supp.
90        information); activated with: solar_exponent=0. and wv_exponent=-1.
91    o pkg/ggl90:
92      - within IDEMIX add upper limit for horizontal group velocity to
93        avoid instability problems in the explicit horizontal diffusion term for
94        long time steps or high resolution
95    o pkg/diagnostics:
96      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
97        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
98    o testreport:
99      - remove "-v" (verbose option) in default mpirun command.
100    o pkg/seaice/seaice_growth:
101      - catch potential division by zero in ITD code, does not change
102        verification results
103    o pkg/ecco:
104      - retire old codes to the Attic. The calls to retired functions are
105        left in a commented form in case they ever need to be re-activated.
106      - ecco_check.F: issue warning if any old CPP option is
107        defined that corresponds to retired codes -- then stop.
108    o pkg/atm_compon_interf:
109      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
110        coupler: use last time-step value instead of average over cplSendFrq_iter
111        time-step, similar to what is done for seaIceMass.
112        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
113    o eesupp & genmake2:
114      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
115        <= remove until a fix is found for some ifort version on ia32 machine.
116    o pkg/seaice/seaice_evp:
117      - refine residual computation
118    
119    checkpoint65q (2015/11/18)
120    o pkg/seaice/seaice_evp:
121      - fix residual computations so that they no longer affect the actual
122        simulation code
123      - fix seaice_readparams to be able to actually set new parameters
124        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
125    o model/src:
126      - fix wrong truncation (single prec) from "FLOAT" function in expressions
127        like: deltaT*FLOAT(myIter) when myIter is large:
128         a) replaced by DFLOAT (if not seen by TAF);
129         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
130    o pkg/aim_v23:
131      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
132        when pickupSuff is set ; do write rolling pickups + at the end of the run.
133    o pkg/atm_ocn_coupler + ocn_compon_interf:
134      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
135        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
136        add corresponding call in DO_OCEANIC_PHYS.
137    o coupler pkgs:
138      Start a new way to set-up optionally-exchanged variables (previously, only
139       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
140       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
141       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
142       compononent param default can be set accordingly).
143      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
144       but rather applies to a group a fields (going both ways like for DIC)
145       and corresponds to an option of coupling config.
146      coupler (pkg/atm_ocn_coupler):
147      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
148        and read namelist directly (without eessup S/R calls) instead of
149        in the very un-flexible old way, 1 param per line, in fixed order;
150      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
151        cleanly in CPL_CHECK_CPLCONFIG
152      - add new coupling-exchange selectors (some not yet active) including
153        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
154                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
155      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
156        component ; called directly from coupler.F, after comp. registrations;
157      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
158         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
159          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
160      components (pkg/atm_ & ocn_compon_interf):
161      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
162        CPP header file in all pkg source files.
163      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
164        ATM/OCN_CHECK_CPLCONFIG;
165      - add error-counter to track errors (e.g., in "data.cpl") and to stop
166        cleanly in ATM/OCN_CHECK_CPLCONFIG;
167      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
168        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
169        before PACKAGES_READPARMS;
170      verification/cpl_aim+ocn/:
171      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
172        "data.cpl" for coupler (in input_cpl).
173    o eesupp/inc:
174      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
175        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
176        to always cumulate tile local-sum in the same order (still uses
177        MPI_Allreduce like standard code).
178      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
179        that are now identical to standard version (in eesupp/inc).
180    o pkg/shelfice:
181      - add SHELFICETransCoeffTFile for initializing spatially varying
182        heat and salt transfer coefficients
183    o pkg/atm_compon_interf & ocn_compon_interf:
184      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
185        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
186      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
187    o pkg/atm_ocn_coupler:
188      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
189    o pkg/rbcs:
190      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
191        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
192      - add a short report (to STDOUT) about RBCS-mask settings.
193    
194    checkpoint65p (2015/10/23)
195    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
196        there is no adjoint test for EVP, we don't know what it does to the adjoint
197        solution, but at least there are no more recomputation warnings left
198    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
199        a chance of giving the same results as a fully converged VP (JFNK) solver
200    o tools/adjoint_options/adjoint_diva:
201      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
202    o pkg/streamice:
203      - spotted bug in streamice_driving_stress using dyG where should have been dxG
204    o pkg/exf:
205      - remove STOP statement that prevented to use wind or (wind-)stress
206        interpolation for constant-in-time forcing fields (wind/stress period = 0).
207    o pkg/seaice:
208      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
209        5 additionals 2D fields and 6 new store directives
210      - change logic in seaice_readparms.F: EVP code can now be turned on in
211        various ways, setting SEAICE_deltaTev is no longer required,
212        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
213        or SEAICEaEVPcoeff
214    o pkg/shelfice/shelfice_thermodynamics.F
215      - redefining uLoc/vLoc to u/v, instead of 2u/v
216    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
217      - this is an intermediate state of a truely converging EVP that has
218        the potential of outperforming implicit VP methods, I do not recommend
219        using it yet.
220      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
221        and all parameters are hardwired
222      - for convergence it still requires very smooth regularisations, that means,
223        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
224        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
225        specific averaging appears to be required, still subject to tuning
226      - still needs cleaning and I need to turn parameter into runtime parameters
227      - add code to compute and print residuals of iteration, compile with
228        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
229    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
230      that entered with r1.54 on Sep04, 2015, -> update results
231    
232    checkpoint65o (2015/09/14)
233    o pkg/mom_vecinv & mom_common:
234      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
235        called from there.
236      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
237        allows to use Vector-Invariant form in deep atmos and anelastic formulation
238    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
239      and Koenig-Beatty+Holland (2012)
240      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
241      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
242      - requires an extra input argument for S/R seaice_calc_viscosities
243      - tensileStrength's depth dependence is different from Itkin et al. (2015)
244        (to be changed and played with, for now exponential)
245    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
246      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
247        by AREA according to Connelly et al. (2004), JPO.
248      - For EVP and the LSR solver, the implicit part of the drag term is
249        the only non-zero term in the denominator when there is no ice (which
250        prevented running the model with zero ice-ocean drag). If
251        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
252        (or zero main diagonals BU/BV) which need to be caught. A practical
253        consequence is that for open water, the momentum equation reduce
254        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
255        they happen to be zero, often leading to a non-zero solution over
256        open water.
257    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
258        efficient EVP method.
259      - introduce area-weighted averages for e12 (analogously to
260        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
261        remain, but also changing the order of terms in the previous average
262        changed the results as much) -> update experiment
263      - add SEAICE_DELTA_SMOOTHREG code
264      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
265        TEM-code
266      - adjust loop bounds so that only required fields are computed
267      - add new averaging code for zetaZ/deltaZ (again similar to
268        seaice_calc_viscosities.F), inactive by default for now (will change
269        results again), but will replace old code eventually
270    o eesupp/src:
271      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
272        to always cumulate tile local-sum in the same order
273        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
274        Still uses MPI_Allreduce (like standard code) but on array of tiles
275        and should be faster than GLOBAL_SUM_SEND_RECV code.
276      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
277        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
278      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
279         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
280         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
281         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
282         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
283    
284    checkpoint65n (2015/07/29)
285    o pkg/thsice:
286      - add a warning when used with pkg/aim but without updating SST
287        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
288    o pkg/offline:
289      - change where Offline-Fields are loaded, from load_fields_driver.F to
290        directly within FORWARD_STEP, just after updating iter number and time;
291      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
292        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
293       These changes allow:
294        a) to recover exactly on-line results using deltaToffline=deltaTClock,
295        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
296        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
297        time-step, both with GM & KPP files and with recomputing these fields;
298        b) no needs to switch on staggerTimeStep anymore;
299        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
300      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
301    o pkg/offline:
302      - change (rarely used) offset-iteration parameter to an offset time (in s):
303        can easily recover previous offset-iter effect by setting offset-time
304        (offlineTimeOffset) to offset-iter x deltaToffline;
305      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
306        in KPP as part of surface buoyancy forcing) in offline run.
307      - fix ptracers KPP non-local term in the case where KPP is re-computed.
308    o OpenAD
309      - Adding preliminary ggl90 test to OpenAD verification.
310        Config. with ggl90 currently diverges after 64 time steps
311        so will need more work to become more stable
312      - Adding preliminary kpp test to OpenAD verification.
313        required small tweakes in kpp_routines.F
314      - Merge and update from Krishna Narayanan's contrib area:
315        * Add one variable for preliminary OpenAD DIVA
316        * Add replacement time-stepping for OpenAD DIVA
317        * genmake2 flag -diva (but only for OpenAD; preliminary)
318        * required modifs for OAD_support
319        successful preliminary test for tutorial_global_oce_biogeo/
320    o pkg/seaice:
321      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
322      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
323        delta with a smooth function in s/r seaice_calc_viscosity
324        (no effect on EVP)
325      - rename local suffix "sqr" into "sq" for more consistent variable names
326    o pkg/seaice:
327        add new parameter SEAICE_deltaMin that is used ***only***
328        for regularizing Delta (and nothing else, like the parameter
329        which is also used for all sorts of things SEAICE_EPS).
330        Defaults to SEAICE_EPS for backward compatibility only.
331    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
332        the wrong key by inialising it before use -> fixes a recomputation
333        problem but does not fix the gradient
334    o pkg/layers:
335      - move resetting of flux arrays to outside the iLa loop
336        (this caused layers_diapycnal to not work with more than one layer coord.)
337      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
338    o pkg/layers:
339      - remove from common block 3D layers fields (used to diagnose transport
340        in tracer coords) and declare them as local arrays in layers_calc.F
341    o pkg/seaice:
342      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
343        in lab_sea forward experiment (changes results -> updated)
344      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
345    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
346       computations; for SEAICE_VECTORIZE_LSR
347      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
348        sweep to the outside,
349      - remove store directives and add "CADJ loop sequential" directives
350        in analogy to model/src/solve_tridiagonal.F
351      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
352        boundaries to yield more readable code. This has also the charming side
353        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
354        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
355        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
356        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
357        an additional option)
358       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
359       but the adjoint gradients (which are affected by this change) still explode.
360    o coupler (atm & ocn _compon_interf):
361      - avoid using Exch2 IO mapping if not suitable.
362    
363    checkpoint65m (2015/06/15)
364    o pkg/layers:
365      - clean-up old parameters setting (from Sep 2012):
366        + remove old parameters setting from common block (declared locally);
367        + stop if any old parameter is mixed with new parameters;
368        + check for valid or consistent parameter setting (e.g., layers_name)
369      - check that layers_bounds for Pot.Density are in the right range;
370        this is supposed to catch un-updated setting after recently shifting
371        potential density field "prho" by -1000 (now in "sigma" scale).
372    o pkg/layers:
373      - Added missing call to layers_fill for keeping track of tottend in
374        pkg/diagnostics/diagnostics_fill_state.F
375    o pkg/layers:
376      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
377        of diapycnal fluxes
378    o pkg/layers:
379      - reverted changes to interpolation to previous treatment; there
380        was never actually a problem
381    o pkg/layers:
382      - fix interpolation of layers tracers in the presence of partial cells
383      - add lots of new functionality to compute water mass transformation
384        (enabled by CPP flag LAYERS_THERMODYNAMICS)
385      - add new calls from main code (diags_oceanic_surf_flux.F,
386        thermodynamics.F, impldiff.F) and gad to save the necessary fields
387        for layers_thermodynamics calculations
388    o pkg/ptracers:
389      - add capability of stepping a passive tracer forward without advection
390        by setting PTRACERS_advScheme to 0.
391    o pkg/diagnostics:
392      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
393    o pkg/layers:
394      - shift potential density field "prho" by -1000 for density layer averaging so
395        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
396        Note that density bin boundaries (layers_bounds in data.layers) have
397        to be set accordingly (i.e., shifted, in sigma scale).
398    o pkg/layers:
399      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
400      - fix calculation of layer non-weighted velocity and layer probability
401      - add diagnostics for pot.density used for layer averaging
402    o pkg/seaice:
403      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
404        positiveness, modify a few comments and improve variable names,
405      - the changed computation of deltaC affects most seaice-related
406        experiments at the truncation level.
407        seaice_itd.thermo is affected by far the most, with
408        only 7 digits of agreement remaining; update experiments.
409    
410    checkpoint65l (2015/05/04)
411    o pkg/shelfice:
412      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
413        factor drKp1 to zero where it is negative (ie. do not use
414        SHELFICEBoundaryLayer if hFacC>1)
415      - the same for factor drLoc in shelfice_forcing.F
416    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
417        with modules in ptracers, when using testreport option "-small_f"
418    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
419      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
420    o verification/testreport
421      - add new option -small_f
422        with this option testreport first makes the target small_f (*.f files)
423        before running make (all). This is useful for explicit inlining when
424        all sources need to be full available.
425    o pkg/exf/exf_interp.F:
426        remove previous changes related to reverse (decreasing) input grids latitude
427    
428    checkpoint65k (2015/04/01)
429    o pkg/ecco:
430        fix missing cosphi initialization; use eccoiter in place of optimcycle;
431        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
432        instead of active read/write
433    o pkg/ctrl:
434        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
435        instead of active read/write.
436    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
437        return if .NOT.useAUTODIFF
438    o pkg/seaice: add CPP brackets (cost function related).
439    o model/src:
440        add useAUTODIFF run time switch.
441    o pkg/exf/exf_interp.F:
442        add code to allow input grids with latitude starting in the north (i.e. when
443        j=1 corresponds to northern edge of field); modify global_with_exf to test
444        this feature.
445    o verification/testreport:
446      - replace "grep -A3" with POSIX conformal sed command, because there are
447        implementations of grep that cannot do contextual searches
448      - replace "cat -n" by "nl" (two occurrences), because not all implementations
449        of "cat" have the option "-n"
450    o model/src:
451        add new file gsw_teos10.F that contains 3 functions, more or less a copy
452        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
453        convert from conservative to potential temperature. For now they are not
454        called anywhere.
455    o pkg/ggl90: make "useIDEMIX" useful
456      - re-organize code in s/r ggl90_calc a little to move computations that
457        are different for idemix into separate loops (changes verification
458        experiment idemix at truncation level, 12 digits remain -> updated)
459      - requires 2 new 2D fields KappaM, verticalShear
460      - make hFacI and recip_hFacI local 3D variables that are passed to
461        s/r ggl90_idemix
462      - fix and improve some comments
463    
464    checkpoint65j (2015/02/25)
465    o pkg/openad
466      - synchronize seawater.F with version in model/src: replace routine
467        body of sw_temp by calling sw_ptmp and fix/add a few comments.
468    o pkg/mnc:
469      - change default value of pickup_read/write_mnc params to FALSE
470        (since few features are missing in reading MNC pickup files).
471    o model/src:
472      - change default (background) vertical diffusivity for salt to be the
473        temperature (background) vertical diffusivity.
474      - change background vertical diffusivity in vertical mixing pkgs ggl90,
475        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
476        This makes ptracers default diffusivity (that uses salt diffKr) more
477        consistent with vertical mixing schemes.
478    o verification/testreport:
479      - fix typo in "-pcls" option ;
480      - put temp files in /tmp (instead of in local dir)
481      - add option "-ncad" to use genmake2 new option "-nocat4ad"
482      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
483    o pkg/ggl90 (idemix code):
484      - apply few fixes ; add some missing "_d 0" ; update output of exp.
485        global_ocean.90x40x15.idemix
486    o OpenAD
487      - enable active file I/O and begin removal of work-around code
488        for OpenAD for handling control variables (memory vs. active files)
489      - new CPP options file OPENAD_OPTIONS.h
490      - revert to genarr2d gradient check for hs94.1x64x5
491      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
492      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
493    o tools/genmake2:
494      - add option for an alternative Makefile (from Martin) where multiple
495        source files are sent to TAF (instead of all in one file).
496    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
497      - code provided by Carsten Eden as an extension of ggl90
498      - so far the code is turned on within ggl90 by setting a CPP-flag at
499        compile time; a runtime flag implementation is not yet complete
500      - tested in new verification experiment global_ocean.90x40x15.idemix
501    o verification:
502      - reduce length of the AD test run by half for experiments
503        global_ocean.cs32x15 (std + thsice) and isomip
504      - enable active file I/O for OpenAD, adjust verifications accordingly
505      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
506    o verification/testreport:
507      - fix two non-POSIX sed statements so that there are no error messages
508        on Mac OS X
509      - replace hostname -s with hostname | sed 's/\..*$//'
510    o model/src/seawater.F:
511      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
512        (following the matlab code), which would have avoided the bug caught
513        by Matt (see below) in the first place
514    o pkg/shelfice:
515      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
516        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
517      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
518        ice-shelf case (i.e., within surface level).
519      - add config summary in shelfice_check.F
520      - remove global variable recip_SHELFICElatentHeat and replace by a local
521        variable recip_latentHeat
522      - introduce diagnostics for friction velocity uStar (in case of
523        SHELFICEuseGammaFrict)
524      - change verification experiment isomip.htd:
525        + start from pickup (as input_ad at nIter0=8640)
526        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
527        + test SHELFICEuseGammaFrict = .TRUE.
528        + test SHELFICEadvDiffHeatFlux = .TRUE.
529    o model/src:
530      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
531        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
532        update output of experiments global_with_exf.yearly and isomip (all 6).
533    o pkg/shelfice:
534      - change setting of kTopC to also be zero where there is no ice-shelf.
535      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
536        ice-shelf is.
537      - first attempt to get RealFreshWaterFlux effects: for now, only without
538        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
539    o pkg/seaice: add the option to prescribe a fixed thickness PDF
540      for thermodynamic calculations
541      - because of divisions of the type 7/7 not exactly equal to 1, this change
542        affects results of some verification experiments by up to 4 digits:
543        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
544        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
545        adjoint: lab_sea, lab_sea.noseaicedyn
546        -> updated
547    
548    checkpoint65i (2015/01/23)
549    o model/src:
550      - change units of frictionHeating field from W to W/m^2
551      - fix bug in frictional heating from stratospheric drag in
552        S/R ATM_PHYS_TENDENCY_APPLY_V
553      - with synchronous time-stepping: move resetting to zero of frictionHeating
554        field from load_fields_driver.F to thermodynamics.F ;
555      - add diagnostics for frictional heating.
556    o model/src & gmredi K3D:
557      - add frictionHeating field to pickup-files (for synchronous time-stepping)
558      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
559      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
560        and name in pickup file).
561      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
562    o model/src:
563      - move (from ini_forcing.F) initialisation of all arrays in header file
564        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
565        (since Nov 2012) with option selectAddFluid=1.
566    o pkg/shelfice:
567      - change units (+ document) of newly added field "shelfIceMassDynTendency"
568      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
569    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
570    o pkg/seaice: two new runtime parameters:
571      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
572        long overdue
573      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
574        parameterization of tensil stress for fast ice (does not do anything yet)
575    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
576        for LSR: move checking overlaps out of JFNK-if-block
577    o pkg/atm_phys:
578      - move copy of grid and dynamical fields out of atm_phys_driver.F into
579        new S/R ATM_PHYS_DYN2PHYS.
580      - fix level height for Linear Free-Surf case (to be consistent with
581        fixed-in-time pressure levels).
582    o pkg/mom_common (bottomdrag):
583      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
584        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
585        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
586    o pkg/shelfice (u/v_drag):
587      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
588      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
589        (now similar to shelfice_u_drag.F)
590      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
591        from mom_vecinv.F (similar to mom_fluxform calls).
592    o pkg/mom_common (bottomdrag):
593      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
594      - add options for alternative discretisation of velocity norm in quadratic
595        bottom drag: averaging of grid-cell-center KE to U.point and V.point
596        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
597        improves when averaging only the other component (e.g. vVel for U bottom
598        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
599      - add options (bottomVisc_pCell) to account for partial-cell in bottom
600        friction (no-slip BC) thus getting the true distance from the bottom;
601        off by default since this also reduces model stability (explicit bottom
602        friction). Changes produce different machine truncation with linear-drag
603        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
604        front_relax (bvp & mxl, 10 & 11 digits).
605    o model/src & mom pkgs:
606      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
607        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
608      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
609        just copy level Nr value to level Nr+1.
610    o doc:
611      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
612    o pkg/streamice:
613      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
614        SHELFICE.h: move array shelficemass to init_varia, initialise
615        from array shelficemassinit, which is set in init_fixed and
616        has option to be set from file; introduce array
617        shelficeMassDynTend array, set thru file in init_fixed
618      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
619        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
620        pkg/streamice
621      - shelfice_thermodynamics.F: call shelfice_step_icemass if
622        SHELFICEMassStepping = .true.
623      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
624    
625    checkpoint65h (2014/12/17)
626    o verification/global_ocean.90x40x15, global_ocean_ebm:
627      - update to generic controls.
628    o pkg/ctrl:
629      - ctrl_map_ini_genarr.F: test for igen>0
630      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
631      - move gentim2d part of ctrl_map_ini_genarr.F to
632        new separate routine : ctrl_map_ini_gentim2d.F
633      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
634        add time variable weights and cyclic controls (time mean,
635        seasonal cycle, etc) capabilities to gentim2d
636    o pkg/ecco:
637      - move reading of error, conversion to weights from
638        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
639    o global_oce_llc90, cs32:
640      - activte sbo.
641      - CTRL_SIZE.h : add maxCtrlProc.
642      - activate the new genctrl capabilities.
643      - update following reorganization of global_oce_input_fields.tar.gz  
644    o pkg/ctrl/ctrl_ad_diff.list:
645      - add missing ctrl_init_rec.f
646    o tools/OAD_support/keepOriginal:
647      - add ctrl_init_rec.F
648    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
649      - avoid recomputations of xx_gentim2d_dummy.
650    o momentum diagnostics:
651      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
652        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
653    o pkg/seaice/seaice_lsr.F:
654      - fix computation of BU/BV, make sure they are non-zero, only necessary
655        for cubed sphere exchanges and SEAICE_OLx/y>0.
656        This makes calling s/r fill_cs_corner_rl obsolete (removed).
657    o verification/global_ocean.cs32x15/input.seaice
658      - add test for strong implicit coupling and restricted addtive Schwarz
659        methods for LSR
660      - update results/output.seaice.txt
661    o verification/tutorial_global_oce_biogeo:
662      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
663        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
664        update output_adm,_oadm,_tlm.txt
665    o pkg/dic:
666      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
667      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
668        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
669    o verification/tutorial_global_oce_biogeo:
670      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
671        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
672        update output_adm,_oadm,_tlm.txt
673    o eesupp/src:
674      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
675        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
676    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
677      LSR (following Hutchings et al. 2004)
678      - introduce zetaZ as a global variable (requires adjustments in
679        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
680        in seaice_calc_viscosities.F
681      - new flag SEAICEuseStrImpCpl (default off)
682      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
683        momentum equations
684      - JFNK-solver (preconditioner) adjusted to allow using this method
685        (where it does not have any positive effect)
686    o pkg/seaice
687      - add overlap for restrictive additive Schwartz method also to LSR, but
688        turn it off by default (because it only seems to work for non-cubed
689        sphere/llc topologies)
690    o pkg/autodiff
691      - add extra exchanges in addummy_in_steppging also for mnc output
692    o pkg/seaice:
693      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
694        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
695    o pkg/obcs:
696      - add option to specify domain-connected piece Id along OB though files
697        (for now, only used to diagnose PhiVel; default =1 -> global correction)
698      - modify obcs_diag_balance.F to process each connected-part separately;
699        exclude OB where Id = 0 but keep the full divergence there (-> constant
700        Psi along this portion of OB and all inflow derived from grad(Phi))
701      - add example of OB-conect files in verification/so_box_biogeo/input.
702    o pkg/diagnostics:
703      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
704      a) use non zero matrix element across OB and solve for Phi 1 grid point
705         outside OB (i.e, where tracer OBCS are applied).
706      b) global imbalance of inFlow/outFlow across OB: instead of modifying
707         velocity across OB, spread it uniformly along the OB in the RHS.
708    
709    checkpoint65g (2014/11/19)
710    o pkg/diagnostcis:
711      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
712    o pkg/my82,pp81,kl10:
713      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
714        field diffKr as background diffusivity to set minimum diffusivity value.
715    o pkg/seaice:
716      - add new parameter SEAICEuseEVPrev (for revisited EVP by
717        Bouillon et al 2013)
718      - add SEAICE_evpAlpha/Beta to namelist
719      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
720        involve trivial re-ordering of divisions/multiplications that should not
721        have any effects, but ... they do change the results of lab_sea.hb87 so
722        that only 2 digits of agreement remain, in line with the general
723        instability/fragility of the evp-code. For now, I do not care and just
724        update the verification experiment
725    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
726      - remove xx_genarr2d_numsmooth etc
727      - use xx_genarr2d_preproc etc instead
728      - carry out smooth_correl2D at initialization stage rather than during
729        time stepping.
730      - get smoothOpNb from xx_gentim2d_preproc
731    o global_oce_cs32 :
732      - add test of generic ecco capabilities.
733    o pkg/exf/exf_getsurfacefluxes.F :
734      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
735    o pkg/ctrl,ecco :
736      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
737        is defined.
738    o pkg/seaice: add diagnostics for Delta (deformation parameter)
739    o model/src:
740      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
741        diffusivity (background) is specified but ignored.
742    o verification:
743      - in testreport, convert hostname to lower case for default output dir name
744    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
745    o pkg/dic: add modifications from Hajoon:
746      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
747      - light attenuation: add self-shading effect by climatological Chlorophyll
748        (read from file).
749    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
750        compiles when SEAICE_ALLOW_DYNAMICS is undefined
751    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
752        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
753        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
754        approach where CPP_OPTIONS.h includes an omnipotent
755        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
756    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
757        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
758    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
759        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
760        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
761    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
762      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
763      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
764      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
765      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
766    o pkg/ctrl,ecco,exf :
767      - remove variables associated with NON-generic costs,
768        unless ECCO_CTRL_DEPRECATED is defined.
769      - remove NON-generic NON-obcs controls,
770        unless ECCO_CTRL_DEPRECATED is defined.
771    o pkg/ctrl : added ctrl_local_params.h
772    o pkg/ecco : added ecco_local_params.h
773    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
774        experiments, which will progressively be removed once the
775        experiments are revised to use only generic controls/costs.
776    
777    checkpoint65f (2014/10/13)
778    o pkg/ctrl, ecco, seaice : minor changes in headers
779    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
780        cost function and control capabilities added since checkpoint65c.

782    o pkg/ecco: increase modularity and improve logic
783      - ecco_toolbox.F (new) : basic operations that are often used,

785        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
786      - cost_gencal.F (new) : determine filnames and records.
787      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
788      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
789        and exploit the above functions leading to more compact code.
790      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
791      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
792        using_ers, using_gfo, using_mdt is now only defined within gencost)
793    o pkg/ecco: extend generic cost capabilities
794      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
795        capabilities via gencost_preproc (+ _c,_i,_r related params),
796        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
797        gencost_outputlevel arguments to cost_generic
798      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
799        and active_read, making room for gencost_preproc to take effect.
800        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
801      - pkg/ecco/cost_generic.F :
802        compute and store misfit maks*(model-data) in localdif that is
803        then used in cost and for output, output misfit if outlev.GT.0
804      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
805        rather gencost_barfile for deciding whether to write barfile
806      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
807      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
808        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
809      - pkg/ecco/ecco_summary.F : report gencost variables
810      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
811    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
812    o pkg/ecco: internal re-organization
813      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
814        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
815        mv relevant variables definition from ecco_cost.h to ecco.h,
816        make sure gencost routines only include ecco.h)
817      - throughout : add missing CCP switches, rm unused variables,
818        and rm un-necessary CPP switches
819      - throughout gencost routines : replace modelstartdate with
820        gencost_startdate when needed
821      - cost_bp_read.F : use arguments, instead of common blocs
822        so that it can be used also by (new) cost_gencost_bpv4.F
823      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
824      - ecco_phys.F : compute etanFull
825      - ecco_readparms.F : rename using_topex as using_tpj, add
826        bpv4-grace to gencost list, initialize added parameters
827      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
828    
829    checkpoint65e (2014/09/28)
830    o pkg/obcs:
831      - replaced the just-added CPP options with run-time variables
832        (see pkg/obcs/OBCS_PARAMS.h for details)
833    o pkg/obcs:
834      - add additional CPP options for sponge boundary layers
835        (see pkg/obcs/OBCS_OPTIONS.h for details)
836    o pkg/atm_phys:
837      - implement simple (obliquity only, assuming circular planet orbit)
838        seasonal cycle for incoming insolation ; used when run-time parameter
839        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
840    o pkg/exf, pkg/ecco, pkg/ctrl:
841      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
842      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
843      - implement gentim2d for xx_tauu, xx_tauv
844    o pkg/ctrl, pkg/ecco :
845      - fix and complement the generic controls implementation
846    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
847        pkg/shelfice/shelfice_thermodynamics.F,
848        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
849        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
850      - add weight in CTRL_GET_GEN calls
851    o pkg/ctrl :
852      - ctrl_get_gen.F : add weight as input parameter, and apply
853        it directly rather than using smooth_correl2Dw (to be retired).
854      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
855    o pkg/ctrl :
856      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
857        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
858      - re-activate ctrl_summary (call in ctrl_init.F)

865      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
866    
867    checkpoint65d (2014/09/15)
868    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
869      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
870        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
871    o pkg/ctrl/ctrl_map_ini_genarr.F :
872      - remove compilation failure
873      - replace hard coded example
874      - use ctrl_map_ini_gen2D, 3D
875    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
876      - on/off switch based upon xx_genarr2d_weight,3d
877    o src/packages_init_variables.F :
878      - regroup pkg/estimation calls
879      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
880        (moved to ctrl_init_variables)
881    o cost/cost_init_varia.F :
882      - remove ecco_cost_init_varia
883        (moved to ecco_init_varia)
884    o ctrl/ctrl_init_variables.F :

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