4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o tools:
8      - add a hack in "remove_comments_sed" (used only with TAF) for recent
9        version of OpenMPI (shipped with FC.23): comment out the new header
10        file "mpif-sizeof.h" which causes problems to TAF.
11    o pkg/seaice:
12      - change the termination criterion so that maxits (SEAICElinearIterMax)
13        has an effect
14      - unify iteration parameters for implicit solvers (JFNK and Picard)
15        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
16        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
17        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
18        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
19        SEAICEnonLinTol     replaces JFNKgamma_nonlin
20      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
21      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
22        use with SEAICEuseKrylov
23    o pkg/seaice/seaice_lsr.F
24        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
25        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
26        an effect.
27    o pkg/seaice: add two new parameters
28      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
29        parameter is not in any namelist)
30      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
31        a preconditioner for the non-linear Newton iteration of the JFNK
32        solver
33    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
34      affects some experiments at truncation level:
35      - global_ocean.cs32x15.icedyn (11 digits),
36      - global_ocean.cs32x15.seaice (11 digits),
37      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
38      - also update global_ocean.cs32x15 adjoint and tangent-linear results
39    o pkg/salt_plume & pkg/thsice:
40      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
41        connect salt_plume flux to ATM-OCN coupling pkgs interface:
42       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
43         export to coupler interface) even without compiling pkg/salt_plume ;
44       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
45         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
46    o pkg/dic:
47      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
48        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
49        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
50      - move also update with values from ATM-OCN Coupler in the same new S/R
51        (previously done in ocn_apply_import.F).
52    o tools/adjoint_options:
53      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
54        has been changed on Jan 14, 2016.
55    o pkg/ggl90:
56      - add alternative discretisation of vertical shear (off by default), to
57        compute the mean (@ grid-cell center) of vertical shear compon instead of
58        vertical shear of mean flow (@ grid-cell center).
59      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
60        results on adjacent faces of cubed-sphere grids; this fix the restart.
61    o pkg/atm_compon_interf:
62      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
63        pass last value, stored directly before export to CPL ;
64        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
65      - remove atmSLPr from pickup files (no longer needed for restart)
66    
67    checkpoint65s (2016/01/13)
68    o eesupp & genmake2:
69       - first check for Function ETIME and, if it fails, then check for subroutine
70         ETIME and consistent output; use the appropriate version in timers.F
71    o model/src:
72      - to check restart test, add option to apply EXCH to U,V earlier, just before
73        integr_continuity; turned off by default.
74    o pkg/dic:
75      - remove CPP option USE_ATMOSCO2 (not needed)
76    o tools/tst_2+2:
77      - try to ignore difference between +0 and -0 in binary file, causing test
78        to fail for no good reason.
79    o eesupp & genmake2:
80      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
81        but also check (in genmake2) that test runs and returns meaningful results.
82    o coupler pkgs:
83      Finish implementation of optionally-exchanged variable switches (started on
84       Nov 12) with addition of few more exchanged fields, including 2-way exchange
85       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
86       advection in OCN component; this requires sequential coupling.
87      coupler (pkg/atm_ocn_coupler):
88      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
89        routines (useful for debug).
90      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
91         flux, DIC fields) if corresponding switch is ON.
92      - add option to export RunOff to OCN (to use for DIC river input)
93      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
94      components (pkg/atm_ & ocn_compon_interf):
95      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
96        optionally exchanged fields; add a check & stop in cpl_readparms.F.
97        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
98        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
99      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
100        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
101      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
102      - hold in common block coupler optionally-exchanged variable switch
103        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
104      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
105        this is intended to replace the OCN cplFldtave.* output files (not updated
106        to contain new additional exchanged fields).
107    o pkg/dic:
108      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
109    o pkg/thsice:
110      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
111        and writing of thsice pickup files.
112    o pkg/atm_compon_interf:
113      - move all field individual export-call out of cpl_export_import_data.F
114        into new S/R ATM_EXPORT_FIELDS
115    o pkg/atm_compon_interf:
116      - store state variables (for now, only thSIce fields) just before beeing
117        exported (in cpl_export_import_data.F, like on ocean side) instead of from
118        atm_store_my_data.F like all exported fluxes.
119      - new version of pickup_cpl: write field names into meta file and read meta
120        file to find field postion in pickup. Also only write/read fields meeded for
121        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
122    o pkg/dic:
123      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
124    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
125        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
126        value can be from domain [0,1] to average between the two methods
127    o pkg/atm_phys:
128      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
129        hold fixed in time).
130    
131    checkpoint65r (2015/12/21)
132    o pkg/seaice:
133        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
134        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
135    o pkg/seaice:
136      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
137        when SEAICEscaleSurfStress=.TRUE.,
138      - apply areaW and areaS in S/R seaice_calc_lhs
139    o pkg/atm_phys:
140      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
141        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
142        for individual contribution (convection, LSC cond, radiation)
143      - add Ruth Geen etal, GRL 2016, radiation optionis (see paper supp.
144        information); activated with: solar_exponent=0. and wv_exponent=-1.
145    o pkg/ggl90:
146      - within IDEMIX add upper limit for horizontal group velocity to
147        avoid instability problems in the explicit horizontal diffusion term for
148        long time steps or high resolution
149    o pkg/diagnostics:
150      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
151        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
152    o testreport:
153      - remove "-v" (verbose option) in default mpirun command.
154    o pkg/seaice/seaice_growth:
155      - catch potential division by zero in ITD code, does not change
156        verification results
157    o pkg/ecco:
158      - retire old codes to the Attic. The calls to retired functions are
159        left in a commented form in case they ever need to be re-activated.
160      - ecco_check.F: issue warning if any old CPP option is
161        defined that corresponds to retired codes -- then stop.
162    o pkg/atm_compon_interf:
163      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
164        coupler: use last time-step value instead of average over cplSendFrq_iter
165        time-step, similar to what is done for seaIceMass.
166        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
167    o eesupp & genmake2:
168      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
169        <= remove until a fix is found for some ifort version on ia32 machine.
170    o pkg/seaice/seaice_evp:
171      - refine residual computation
172    
173    checkpoint65q (2015/11/18)
174    o pkg/seaice/seaice_evp:
175      - fix residual computations so that they no longer affect the actual
176        simulation code
177      - fix seaice_readparams to be able to actually set new parameters
178        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
179    o model/src:
180      - fix wrong truncation (single prec) from "FLOAT" function in expressions
181        like: deltaT*FLOAT(myIter) when myIter is large:
182         a) replaced by DFLOAT (if not seen by TAF);
183         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
184    o pkg/aim_v23:
185      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
186        when pickupSuff is set ; do write rolling pickups + at the end of the run.
187    o pkg/atm_ocn_coupler + ocn_compon_interf:
188      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
189        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
190        add corresponding call in DO_OCEANIC_PHYS.
191    o coupler pkgs:
192      Start a new way to set-up optionally-exchanged variables (previously, only
193       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
194       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
195       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
196       compononent param default can be set accordingly).
197      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
198       but rather applies to a group a fields (going both ways like for DIC)
199       and corresponds to an option of coupling config.
200      coupler (pkg/atm_ocn_coupler):
201      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
202        and read namelist directly (without eessup S/R calls) instead of
203        in the very un-flexible old way, 1 param per line, in fixed order;
204      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
205        cleanly in CPL_CHECK_CPLCONFIG
206      - add new coupling-exchange selectors (some not yet active) including
207        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
208                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
209      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
210        component ; called directly from coupler.F, after comp. registrations;
211      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
212         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
213          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
214      components (pkg/atm_ & ocn_compon_interf):
215      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
216        CPP header file in all pkg source files.
217      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
218        ATM/OCN_CHECK_CPLCONFIG;
219      - add error-counter to track errors (e.g., in "data.cpl") and to stop
220        cleanly in ATM/OCN_CHECK_CPLCONFIG;
221      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
222        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
223        before PACKAGES_READPARMS;
224      verification/cpl_aim+ocn/:
225      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
226        "data.cpl" for coupler (in input_cpl).
227    o eesupp/inc:
228      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
229        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
230        to always cumulate tile local-sum in the same order (still uses
231        MPI_Allreduce like standard code).
232      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
233        that are now identical to standard version (in eesupp/inc).
234    o pkg/shelfice:
235      - add SHELFICETransCoeffTFile for initializing spatially varying
236        heat and salt transfer coefficients
237    o pkg/atm_compon_interf & ocn_compon_interf:
238      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
239        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
240      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
241    o pkg/atm_ocn_coupler:
242      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
243    o pkg/rbcs:
244      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
245        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
246      - add a short report (to STDOUT) about RBCS-mask settings.
247    
248    checkpoint65p (2015/10/23)
249    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
250        there is no adjoint test for EVP, we don't know what it does to the adjoint
251        solution, but at least there are no more recomputation warnings left
252    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
253        a chance of giving the same results as a fully converged VP (JFNK) solver
254    o tools/adjoint_options/adjoint_diva:
255      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
256    o pkg/streamice:
257      - spotted bug in streamice_driving_stress using dyG where should have been dxG
258    o pkg/exf:
259      - remove STOP statement that prevented to use wind or (wind-)stress
260        interpolation for constant-in-time forcing fields (wind/stress period = 0).
261    o pkg/seaice:
262      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
263        5 additionals 2D fields and 6 new store directives
264      - change logic in seaice_readparms.F: EVP code can now be turned on in
265        various ways, setting SEAICE_deltaTev is no longer required,
266        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
267        or SEAICEaEVPcoeff
268    o pkg/shelfice/shelfice_thermodynamics.F
269      - redefining uLoc/vLoc to u/v, instead of 2u/v
270    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
271      - this is an intermediate state of a truely converging EVP that has
272        the potential of outperforming implicit VP methods, I do not recommend
273        using it yet.
274      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
275        and all parameters are hardwired
276      - for convergence it still requires very smooth regularisations, that means,
277        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
278        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
279        specific averaging appears to be required, still subject to tuning
280      - still needs cleaning and I need to turn parameter into runtime parameters
281      - add code to compute and print residuals of iteration, compile with
282        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
283    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
284      that entered with r1.54 on Sep04, 2015, -> update results
285    
286    checkpoint65o (2015/09/14)
287    o pkg/mom_vecinv & mom_common:
288      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
289        called from there.
290      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
291        allows to use Vector-Invariant form in deep atmos and anelastic formulation
292    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
293      and Koenig-Beatty+Holland (2012)
294      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
295      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
296      - requires an extra input argument for S/R seaice_calc_viscosities
297      - tensileStrength's depth dependence is different from Itkin et al. (2015)
298        (to be changed and played with, for now exponential)
299    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
300      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
301        by AREA according to Connelly et al. (2004), JPO.
302      - For EVP and the LSR solver, the implicit part of the drag term is
303        the only non-zero term in the denominator when there is no ice (which
304        prevented running the model with zero ice-ocean drag). If
305        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
306        (or zero main diagonals BU/BV) which need to be caught. A practical
307        consequence is that for open water, the momentum equation reduce
308        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
309        they happen to be zero, often leading to a non-zero solution over
310        open water.
311    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
312        efficient EVP method.
313      - introduce area-weighted averages for e12 (analogously to
314        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
315        remain, but also changing the order of terms in the previous average
316        changed the results as much) -> update experiment
317      - add SEAICE_DELTA_SMOOTHREG code
318      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
319        TEM-code
320      - adjust loop bounds so that only required fields are computed
321      - add new averaging code for zetaZ/deltaZ (again similar to
322        seaice_calc_viscosities.F), inactive by default for now (will change
323        results again), but will replace old code eventually
324    o eesupp/src:
325      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
326        to always cumulate tile local-sum in the same order
327        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
328        Still uses MPI_Allreduce (like standard code) but on array of tiles
329        and should be faster than GLOBAL_SUM_SEND_RECV code.
330      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
331        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
332      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:

338    checkpoint65n (2015/07/29)
339    o pkg/thsice:
340      - add a warning when used with pkg/aim but without updating SST
341        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
342    o pkg/offline:
343      - change where Offline-Fields are loaded, from load_fields_driver.F to
344        directly within FORWARD_STEP, just after updating iter number and time;
345      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
346        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
347       These changes allow:
348        a) to recover exactly on-line results using deltaToffline=deltaTClock,
349        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
350        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
351        time-step, both with GM & KPP files and with recomputing these fields;
352        b) no needs to switch on staggerTimeStep anymore;
353        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
354      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
355    o pkg/offline:
356      - change (rarely used) offset-iteration parameter to an offset time (in s):
357        can easily recover previous offset-iter effect by setting offset-time
358        (offlineTimeOffset) to offset-iter x deltaToffline;
359      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
360        in KPP as part of surface buoyancy forcing) in offline run.
361      - fix ptracers KPP non-local term in the case where KPP is re-computed.
362    o OpenAD
363      - Adding preliminary ggl90 test to OpenAD verification.
364        Config. with ggl90 currently diverges after 64 time steps
365        so will need more work to become more stable
366      - Adding preliminary kpp test to OpenAD verification.
367        required small tweakes in kpp_routines.F
368      - Merge and update from Krishna Narayanan's contrib area:
369        * Add one variable for preliminary OpenAD DIVA
370        * Add replacement time-stepping for OpenAD DIVA
371        * genmake2 flag -diva (but only for OpenAD; preliminary)
372        * required modifs for OAD_support
373        successful preliminary test for tutorial_global_oce_biogeo/
374    o pkg/seaice:
375      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
376      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
377        delta with a smooth function in s/r seaice_calc_viscosity
378        (no effect on EVP)
379      - rename local suffix "sqr" into "sq" for more consistent variable names
380    o pkg/seaice:
381        add new parameter SEAICE_deltaMin that is used ***only***
382        for regularizing Delta (and nothing else, like the parameter
383        which is also used for all sorts of things SEAICE_EPS).
384        Defaults to SEAICE_EPS for backward compatibility only.
385    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
386        the wrong key by inialising it before use -> fixes a recomputation
387        problem but does not fix the gradient
388    o pkg/layers:
389      - move resetting of flux arrays to outside the iLa loop
390        (this caused layers_diapycnal to not work with more than one layer coord.)
391      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
392    o pkg/layers:
393      - remove from common block 3D layers fields (used to diagnose transport
394        in tracer coords) and declare them as local arrays in layers_calc.F
395    o pkg/seaice:
396      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
397        in lab_sea forward experiment (changes results -> updated)
398      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
399    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
400       computations; for SEAICE_VECTORIZE_LSR
401      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
402        sweep to the outside,
403      - remove store directives and add "CADJ loop sequential" directives
404        in analogy to model/src/solve_tridiagonal.F
405      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
406        boundaries to yield more readable code. This has also the charming side
407        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
408        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
409        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
410        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
411        an additional option)
412       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
413       but the adjoint gradients (which are affected by this change) still explode.
414    o coupler (atm & ocn _compon_interf):
415      - avoid using Exch2 IO mapping if not suitable.
416    
417    checkpoint65m (2015/06/15)
418    o pkg/layers:
419      - clean-up old parameters setting (from Sep 2012):
420        + remove old parameters setting from common block (declared locally);
421        + stop if any old parameter is mixed with new parameters;
422        + check for valid or consistent parameter setting (e.g., layers_name)
423      - check that layers_bounds for Pot.Density are in the right range;
424        this is supposed to catch un-updated setting after recently shifting
425        potential density field "prho" by -1000 (now in "sigma" scale).
426    o pkg/layers:
427      - Added missing call to layers_fill for keeping track of tottend in
428        pkg/diagnostics/diagnostics_fill_state.F
429    o pkg/layers:
430      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
431        of diapycnal fluxes
432    o pkg/layers:
433      - reverted changes to interpolation to previous treatment; there
434        was never actually a problem
435    o pkg/layers:
436      - fix interpolation of layers tracers in the presence of partial cells
437      - add lots of new functionality to compute water mass transformation
438        (enabled by CPP flag LAYERS_THERMODYNAMICS)
439      - add new calls from main code (diags_oceanic_surf_flux.F,
440        thermodynamics.F, impldiff.F) and gad to save the necessary fields
441        for layers_thermodynamics calculations
442    o pkg/ptracers:
443      - add capability of stepping a passive tracer forward without advection
444        by setting PTRACERS_advScheme to 0.
445    o pkg/diagnostics:
446      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
447    o pkg/layers:
448      - shift potential density field "prho" by -1000 for density layer averaging so
449        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
450        Note that density bin boundaries (layers_bounds in data.layers) have
451        to be set accordingly (i.e., shifted, in sigma scale).
452    o pkg/layers:
453      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
454      - fix calculation of layer non-weighted velocity and layer probability
455      - add diagnostics for pot.density used for layer averaging
456    o pkg/seaice:
457      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
458        positiveness, modify a few comments and improve variable names,
459      - the changed computation of deltaC affects most seaice-related
460        experiments at the truncation level.
461        seaice_itd.thermo is affected by far the most, with
462        only 7 digits of agreement remaining; update experiments.
463    
464    checkpoint65l (2015/05/04)
465    o pkg/shelfice:
466      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
467        factor drKp1 to zero where it is negative (ie. do not use
468        SHELFICEBoundaryLayer if hFacC>1)
469      - the same for factor drLoc in shelfice_forcing.F
470    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
471        with modules in ptracers, when using testreport option "-small_f"
472    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
473      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
474    o verification/testreport
475      - add new option -small_f
476        with this option testreport first makes the target small_f (*.f files)
477        before running make (all). This is useful for explicit inlining when
478        all sources need to be full available.
479    o pkg/exf/exf_interp.F:
480        remove previous changes related to reverse (decreasing) input grids latitude
481    
482    checkpoint65k (2015/04/01)
483    o pkg/ecco:
484        fix missing cosphi initialization; use eccoiter in place of optimcycle;
485        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
486        instead of active read/write
487    o pkg/ctrl:
488        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
489        instead of active read/write.
490    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
491        return if .NOT.useAUTODIFF
492    o pkg/seaice: add CPP brackets (cost function related).
493    o model/src:
494        add useAUTODIFF run time switch.
495    o pkg/exf/exf_interp.F:
496        add code to allow input grids with latitude starting in the north (i.e. when
497        j=1 corresponds to northern edge of field); modify global_with_exf to test
498        this feature.
499    o verification/testreport:
500      - replace "grep -A3" with POSIX conformal sed command, because there are
501        implementations of grep that cannot do contextual searches
502      - replace "cat -n" by "nl" (two occurrences), because not all implementations
503        of "cat" have the option "-n"
504    o model/src:
505        add new file gsw_teos10.F that contains 3 functions, more or less a copy
506        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
507        convert from conservative to potential temperature. For now they are not
508        called anywhere.
509    o pkg/ggl90: make "useIDEMIX" useful
510      - re-organize code in s/r ggl90_calc a little to move computations that
511        are different for idemix into separate loops (changes verification
512        experiment idemix at truncation level, 12 digits remain -> updated)
513      - requires 2 new 2D fields KappaM, verticalShear
514      - make hFacI and recip_hFacI local 3D variables that are passed to
515        s/r ggl90_idemix
516      - fix and improve some comments
517    
518    checkpoint65j (2015/02/25)
519    o pkg/openad
520      - synchronize seawater.F with version in model/src: replace routine
521        body of sw_temp by calling sw_ptmp and fix/add a few comments.
522    o pkg/mnc:
523      - change default value of pickup_read/write_mnc params to FALSE
524        (since few features are missing in reading MNC pickup files).
525    o model/src:
526      - change default (background) vertical diffusivity for salt to be the
527        temperature (background) vertical diffusivity.
528      - change background vertical diffusivity in vertical mixing pkgs ggl90,
529        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
530        This makes ptracers default diffusivity (that uses salt diffKr) more
531        consistent with vertical mixing schemes.
532    o verification/testreport:
533      - fix typo in "-pcls" option ;
534      - put temp files in /tmp (instead of in local dir)
535      - add option "-ncad" to use genmake2 new option "-nocat4ad"
536      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
537    o pkg/ggl90 (idemix code):
538      - apply few fixes ; add some missing "_d 0" ; update output of exp.
539        global_ocean.90x40x15.idemix
540    o OpenAD
541      - enable active file I/O and begin removal of work-around code
542        for OpenAD for handling control variables (memory vs. active files)
543      - new CPP options file OPENAD_OPTIONS.h
544      - revert to genarr2d gradient check for hs94.1x64x5
545      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
546      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
547    o tools/genmake2:
548      - add option for an alternative Makefile (from Martin) where multiple
549        source files are sent to TAF (instead of all in one file).
550    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
551      - code provided by Carsten Eden as an extension of ggl90
552      - so far the code is turned on within ggl90 by setting a CPP-flag at
553        compile time; a runtime flag implementation is not yet complete
554      - tested in new verification experiment global_ocean.90x40x15.idemix
555    o verification:
556      - reduce length of the AD test run by half for experiments
557        global_ocean.cs32x15 (std + thsice) and isomip
558      - enable active file I/O for OpenAD, adjust verifications accordingly
559      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
560    o verification/testreport:
561      - fix two non-POSIX sed statements so that there are no error messages
562        on Mac OS X
563      - replace hostname -s with hostname | sed 's/\..*$//'
564    o model/src/seawater.F:
565      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
566        (following the matlab code), which would have avoided the bug caught
567        by Matt (see below) in the first place
568    o pkg/shelfice:
569      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
570        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
571      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
572        ice-shelf case (i.e., within surface level).
573      - add config summary in shelfice_check.F
574      - remove global variable recip_SHELFICElatentHeat and replace by a local
575        variable recip_latentHeat
576      - introduce diagnostics for friction velocity uStar (in case of
577        SHELFICEuseGammaFrict)
578      - change verification experiment isomip.htd:
579        + start from pickup (as input_ad at nIter0=8640)
580        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
581        + test SHELFICEuseGammaFrict = .TRUE.
582        + test SHELFICEadvDiffHeatFlux = .TRUE.
583    o model/src:
584      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
585        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
586        update output of experiments global_with_exf.yearly and isomip (all 6).
587    o pkg/shelfice:
588      - change setting of kTopC to also be zero where there is no ice-shelf.
589      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
590        ice-shelf is.
591      - first attempt to get RealFreshWaterFlux effects: for now, only without
592        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
593    o pkg/seaice: add the option to prescribe a fixed thickness PDF
594      for thermodynamic calculations
595      - because of divisions of the type 7/7 not exactly equal to 1, this change
596        affects results of some verification experiments by up to 4 digits:
597        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
598        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
599        adjoint: lab_sea, lab_sea.noseaicedyn
600        -> updated
601    
602    checkpoint65i (2015/01/23)
603    o model/src:
604      - change units of frictionHeating field from W to W/m^2
605      - fix bug in frictional heating from stratospheric drag in
606        S/R ATM_PHYS_TENDENCY_APPLY_V
607      - with synchronous time-stepping: move resetting to zero of frictionHeating
608        field from load_fields_driver.F to thermodynamics.F ;
609      - add diagnostics for frictional heating.
610    o model/src & gmredi K3D:
611      - add frictionHeating field to pickup-files (for synchronous time-stepping)
612      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
613      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
614        and name in pickup file).
615      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
616    o model/src:
617      - move (from ini_forcing.F) initialisation of all arrays in header file
618        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
619        (since Nov 2012) with option selectAddFluid=1.
620    o pkg/shelfice:
621      - change units (+ document) of newly added field "shelfIceMassDynTendency"
622      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
623    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
624    o pkg/seaice: two new runtime parameters:
625      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
626        long overdue
627      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
628        parameterization of tensil stress for fast ice (does not do anything yet)
629    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
630        for LSR: move checking overlaps out of JFNK-if-block
631    o pkg/atm_phys:
632      - move copy of grid and dynamical fields out of atm_phys_driver.F into
633        new S/R ATM_PHYS_DYN2PHYS.
634      - fix level height for Linear Free-Surf case (to be consistent with
635        fixed-in-time pressure levels).
636    o pkg/mom_common (bottomdrag):
637      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
638        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
639        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
640    o pkg/shelfice (u/v_drag):
641      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
642      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
643        (now similar to shelfice_u_drag.F)
644      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
645        from mom_vecinv.F (similar to mom_fluxform calls).
646    o pkg/mom_common (bottomdrag):
647      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
648      - add options for alternative discretisation of velocity norm in quadratic
649        bottom drag: averaging of grid-cell-center KE to U.point and V.point
650        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
651        improves when averaging only the other component (e.g. vVel for U bottom
652        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
653      - add options (bottomVisc_pCell) to account for partial-cell in bottom
654        friction (no-slip BC) thus getting the true distance from the bottom;
655        off by default since this also reduces model stability (explicit bottom
656        friction). Changes produce different machine truncation with linear-drag
657        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
658        front_relax (bvp & mxl, 10 & 11 digits).
659    o model/src & mom pkgs:
660      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
661        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
662      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
663        just copy level Nr value to level Nr+1.
664    o doc:
665      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
666    o pkg/streamice:
667      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
668        SHELFICE.h: move array shelficemass to init_varia, initialise
669        from array shelficemassinit, which is set in init_fixed and
670        has option to be set from file; introduce array
671        shelficeMassDynTend array, set thru file in init_fixed
672      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
673        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
674        pkg/streamice
675      - shelfice_thermodynamics.F: call shelfice_step_icemass if
676        SHELFICEMassStepping = .true.
677      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
678    
679    checkpoint65h (2014/12/17)
680    o verification/global_ocean.90x40x15, global_ocean_ebm:
681      - update to generic controls.
682    o pkg/ctrl:
683      - ctrl_map_ini_genarr.F: test for igen>0
684      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
685      - move gentim2d part of ctrl_map_ini_genarr.F to
686        new separate routine : ctrl_map_ini_gentim2d.F
687      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
688        add time variable weights and cyclic controls (time mean,
689        seasonal cycle, etc) capabilities to gentim2d
690    o pkg/ecco:
691      - move reading of error, conversion to weights from
692        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
693    o global_oce_llc90, cs32:
694      - activte sbo.
695      - CTRL_SIZE.h : add maxCtrlProc.
696      - activate the new genctrl capabilities.
697      - update following reorganization of global_oce_input_fields.tar.gz  
698    o pkg/ctrl/ctrl_ad_diff.list:
699      - add missing ctrl_init_rec.f
700    o tools/OAD_support/keepOriginal:
701      - add ctrl_init_rec.F
702    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
703      - avoid recomputations of xx_gentim2d_dummy.
704    o momentum diagnostics:
705      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
706        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
707    o pkg/seaice/seaice_lsr.F:
708      - fix computation of BU/BV, make sure they are non-zero, only necessary
709        for cubed sphere exchanges and SEAICE_OLx/y>0.
710        This makes calling s/r fill_cs_corner_rl obsolete (removed).
711    o verification/global_ocean.cs32x15/input.seaice
712      - add test for strong implicit coupling and restricted addtive Schwarz
713        methods for LSR
714      - update results/output.seaice.txt
715    o verification/tutorial_global_oce_biogeo:
716      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
717        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
718        update output_adm,_oadm,_tlm.txt
719    o pkg/dic:
720      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
721      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
722        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
723    o verification/tutorial_global_oce_biogeo:
724      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
725        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
726        update output_adm,_oadm,_tlm.txt
727    o eesupp/src:
728      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
729        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
730    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
731      LSR (following Hutchings et al. 2004)
732      - introduce zetaZ as a global variable (requires adjustments in
733        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
734        in seaice_calc_viscosities.F
735      - new flag SEAICEuseStrImpCpl (default off)
736      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
737        momentum equations
738      - JFNK-solver (preconditioner) adjusted to allow using this method
739        (where it does not have any positive effect)
740    o pkg/seaice
741      - add overlap for restrictive additive Schwartz method also to LSR, but
742        turn it off by default (because it only seems to work for non-cubed
743        sphere/llc topologies)
744    o pkg/autodiff
745      - add extra exchanges in addummy_in_steppging also for mnc output
746    o pkg/seaice:
747      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
748        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
749    o pkg/obcs:
750      - add option to specify domain-connected piece Id along OB though files
751        (for now, only used to diagnose PhiVel; default =1 -> global correction)
752      - modify obcs_diag_balance.F to process each connected-part separately;
753        exclude OB where Id = 0 but keep the full divergence there (-> constant
754        Psi along this portion of OB and all inflow derived from grad(Phi))
755      - add example of OB-conect files in verification/so_box_biogeo/input.
756    o pkg/diagnostics:
757      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
758      a) use non zero matrix element across OB and solve for Phi 1 grid point
759         outside OB (i.e, where tracer OBCS are applied).
760      b) global imbalance of inFlow/outFlow across OB: instead of modifying
761         velocity across OB, spread it uniformly along the OB in the RHS.
762    
763    checkpoint65g (2014/11/19)
764    o pkg/diagnostcis:
765      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
766    o pkg/my82,pp81,kl10:
767      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
768        field diffKr as background diffusivity to set minimum diffusivity value.
769    o pkg/seaice:
770      - add new parameter SEAICEuseEVPrev (for revisited EVP by
771        Bouillon et al 2013)
772      - add SEAICE_evpAlpha/Beta to namelist
773      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
774        involve trivial re-ordering of divisions/multiplications that should not
775        have any effects, but ... they do change the results of lab_sea.hb87 so
776        that only 2 digits of agreement remain, in line with the general
777        instability/fragility of the evp-code. For now, I do not care and just
778        update the verification experiment
779    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
780      - remove xx_genarr2d_numsmooth etc
781      - use xx_genarr2d_preproc etc instead
782      - carry out smooth_correl2D at initialization stage rather than during
783        time stepping.
784      - get smoothOpNb from xx_gentim2d_preproc
785    o global_oce_cs32 :
786      - add test of generic ecco capabilities.
787    o pkg/exf/exf_getsurfacefluxes.F :
788      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
789    o pkg/ctrl,ecco :
790      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
791        is defined.
792    o pkg/seaice: add diagnostics for Delta (deformation parameter)
793    o model/src:
794      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
795        diffusivity (background) is specified but ignored.
796    o verification:
797      - in testreport, convert hostname to lower case for default output dir name
798    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
799    o pkg/dic: add modifications from Hajoon:
800      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
801      - light attenuation: add self-shading effect by climatological Chlorophyll
802        (read from file).
803    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
804        compiles when SEAICE_ALLOW_DYNAMICS is undefined
805    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
806        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
807        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
808        approach where CPP_OPTIONS.h includes an omnipotent
809        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
810    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
811        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
812    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
813        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
814        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
815    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
816      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
817      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
818      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
819      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
820    o pkg/ctrl,ecco,exf :
821      - remove variables associated with NON-generic costs,
822        unless ECCO_CTRL_DEPRECATED is defined.
823      - remove NON-generic NON-obcs controls,
824        unless ECCO_CTRL_DEPRECATED is defined.
825    o pkg/ctrl : added ctrl_local_params.h
826    o pkg/ecco : added ecco_local_params.h
827    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
828        experiments, which will progressively be removed once the
829        experiments are revised to use only generic controls/costs.
830    
831    checkpoint65f (2014/10/13)
832    o pkg/ctrl, ecco, seaice : minor changes in headers
833    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
834        cost function and control capabilities added since checkpoint65c.
835    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
836    o pkg/ecco: increase modularity and improve logic
837      - ecco_toolbox.F (new) : basic operations that are often used,
838        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
839        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
840      - cost_gencal.F (new) : determine filnames and records.
841      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
842      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
843        and exploit the above functions leading to more compact code.
844      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
845      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
846        using_ers, using_gfo, using_mdt is now only defined within gencost)
847    o pkg/ecco: extend generic cost capabilities
848      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
849        capabilities via gencost_preproc (+ _c,_i,_r related params),
850        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
851        gencost_outputlevel arguments to cost_generic
852      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
853        and active_read, making room for gencost_preproc to take effect.
854        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
855      - pkg/ecco/cost_generic.F :
856        compute and store misfit maks*(model-data) in localdif that is
857        then used in cost and for output, output misfit if outlev.GT.0
858      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
859        rather gencost_barfile for deciding whether to write barfile
860      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
861      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
862        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
863      - pkg/ecco/ecco_summary.F : report gencost variables
864      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
865    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
866    o pkg/ecco: internal re-organization
867      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
868        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
869        mv relevant variables definition from ecco_cost.h to ecco.h,
870        make sure gencost routines only include ecco.h)
871      - throughout : add missing CCP switches, rm unused variables,
872        and rm un-necessary CPP switches
873      - throughout gencost routines : replace modelstartdate with
874        gencost_startdate when needed
875      - cost_bp_read.F : use arguments, instead of common blocs
876        so that it can be used also by (new) cost_gencost_bpv4.F
877      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
878      - ecco_phys.F : compute etanFull
879      - ecco_readparms.F : rename using_topex as using_tpj, add
880        bpv4-grace to gencost list, initialize added parameters
881      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
882    
883    checkpoint65e (2014/09/28)
884    o pkg/obcs:
885      - replaced the just-added CPP options with run-time variables
886        (see pkg/obcs/OBCS_PARAMS.h for details)
887    o pkg/obcs:
888      - add additional CPP options for sponge boundary layers
889        (see pkg/obcs/OBCS_OPTIONS.h for details)
890    o pkg/atm_phys:
891      - implement simple (obliquity only, assuming circular planet orbit)
892        seasonal cycle for incoming insolation ; used when run-time parameter
893        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
894    o pkg/exf, pkg/ecco, pkg/ctrl:
895      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
896      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
897      - implement gentim2d for xx_tauu, xx_tauv
898    o pkg/ctrl, pkg/ecco :
899      - fix and complement the generic controls implementation
900    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
901        pkg/shelfice/shelfice_thermodynamics.F,
902        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
903        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
904      - add weight in CTRL_GET_GEN calls
905    o pkg/ctrl :
906      - ctrl_get_gen.F : add weight as input parameter, and apply
907        it directly rather than using smooth_correl2Dw (to be retired).
908      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
909    o pkg/ctrl :
910      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
911        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
912      - re-activate ctrl_summary (call in ctrl_init.F)
913    o pkg/ctrl/ctrl_cost_gen.F :
914      - fix CCP brackets, remove un-necessary myiter, mytime
915    o pkg/ecco, pkg/ctrl :
916      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
917      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
918      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
919      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
920    
921    checkpoint65d (2014/09/15)
922    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
923      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
924        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
925    o pkg/ctrl/ctrl_map_ini_genarr.F :
926      - remove compilation failure
927      - replace hard coded example
928      - use ctrl_map_ini_gen2D, 3D
929    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
930      - on/off switch based upon xx_genarr2d_weight,3d
931    o src/packages_init_variables.F :
932      - regroup pkg/estimation calls
933      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
934        (moved to ctrl_init_variables)
935    o cost/cost_init_varia.F :
936      - remove ecco_cost_init_varia
937        (moved to ecco_init_varia)
938    o ctrl/ctrl_init_variables.F :
939      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
940      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
941    o ctrl/ctrl_map_ini.F :
942      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
943        (moved to ctrl_init_variables)
944    o ctrl/ctrl_map_ini_ecco.F :
945      - remove ECCO_PHYS (mv to ecco_init_varia)
946      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
947    o ecco/ecco_ad_diff.list :
948      - add ecco_init_varia.f
949    o ecco/ecco_init_varia.F
950      - new routine
951    o pkg/streamice:
952      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
953        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
954      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
955    o pkg/generic_advdiff:
956      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
957    o pkg/exf:
958      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
959         xxg_precip capability
960      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
961    o pkg/ctrl:
962      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
963    o model/src/load_fields_driver.F :
964      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
965        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
966    o OpenAD verification experiments:
967      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
968        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
969        for now, only in pkgs used in OpenAD verification experiments.
970      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
971        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
972        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
973        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
974    o OpenAD verification tests:
975      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
976      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
977        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
978      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
979        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
980    o model/src & generic_advdiff:
981      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
982        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
983        dynamics requires valid tracer forcing only over tile interior but, for
984        some diagnostics, may need to extend it over 1 point in tile halo region.
985      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
986        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
987        setting in temp/salt/ptracer_integrate.F
988    o pkg/dic:
989      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
990        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
991        in gchem_forcing_sep.F
992    o pkg/autodiff & obcs:
993      - add storage of current OB values for U & V (was already done for T & S).
994    
995    checkpoint65c (2014/08/30)
996    o pkg/dic:
997      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
998        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
999        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1000    o verification:
1001      - new experiment testing OBCS and DIC pkgs, using params & output from
1002        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1003        passage: take OBCS from the last year of a 2 yrs simulation and initial
1004        conditions from t=1.yr while keeping the same forcing.
1005    o model/src:
1006      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1007        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1008    o pkg/diagnostics (Stats-Diags):
1009      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1010        a) refine region where stats are computed, excluding where arrhFac=0 ;
1011        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1012        c) extend regional stats over the region edges (for U or V pt location).
1013    o pkg/gchem:
1014      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1015        pkg/dic is currently changing/updating ptracers values beyond the OB).
1016    o verification (hs94):
1017      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1018        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1019        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1020        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1021    o pkg/ptracers:
1022      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1023        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1024      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1025        with AB-2 code (so that it get tested).
1026    o model/src:
1027      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1028        with AB-2 code (previously only available with AB-3 code).
1029        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1030        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1031        there, by calling CYCLE_AB_TRACER).
1032    o pkg/generic_advdiff:
1033      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1034        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1035        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1036        S/R temp/salt/ptracers_integrate.F
1037    o model/src & pkg/ptracers:
1038      - remove common block variables gT,gS (in DYNVARS.h), except when
1039         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1040      - remove common block variable gPtr.
1041    o model/src & pkgs:
1042      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1043         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1044         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1045         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1046      + change accordingly all calling S/R.
1047      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1048        in S/R temp/salt/ptracers_integrate.F
1049    o pkg/seaice:
1050      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1051        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1052      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1053        in seaice_lsr
1054      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1055        in s/r seaice_lsr_calc_coeffs
1056    o pkg/mdsio:
1057      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1058        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1059        too long (e.g., > MAX_LEN_FNAM/2 )
1060    
1061    checkpoint65b (2014/08/12)
1062    o pkg/matrix:
1063      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1064    o model/src:
1065      - fix initialisation of geothermalFile; compile geothermal-flux code in
1066        natl_box verification experiment.
1067    o model/src & pkg/down_slope:
1068      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1069      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1070        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1071        results at machine truncation level: update output of experiments
1072        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1073    o pkg/diagnostics (Stats-Diags):
1074      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1075        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1076        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1077        times (but Min,Max and StD are still wrong).
1078    o model/src:
1079      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1080        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1081    o model/src:
1082      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1083        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1084        arrays are already updated while adjustments (filters, conv.adjustment) are
1085        still applied later, in S/R TRACERS_CORRECTION_STEP.
1086    o model/src:
1087      - store in common bloc array "rhoInSitu" the virtual potential temperature
1088        anomaly that is used to compute geopotential: this make the atmos code
1089        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1090    o pkg/seaice/seaice_lsr.F
1091      - rename integer variable ilcall to ipass (that's what it is called
1092        in the residual diagnostics
1093      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1094        default) for improved non-linear convergence of the first few steps
1095      - adjust a few comments and add new ones to explain some of the store
1096        directives
1097    o pkg/generic_advdiff (& ptracers):
1098      - re-work the code to check for valid advection scheme and for minimum
1099        size of overlap (now stored in local common bloc in gad_advscheme.F)
1100    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1101      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1102      - add an auxilliary variable "bet" and fix store directives and keys in
1103        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1104        less exact gradients in my tests); but there are still
1105        recomputation warning (although gradients are sort of OK), when
1106        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1107        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1108      - update verification experiments lab_sea.
1109      - change some comments in S/R seaice_calc_viscosities
1110    o model/src:
1111      - if staggerTimeStep=T, always apply exchange to velocity field in
1112        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1113        (independent of using multi-dim advection or not); no effect on FWD run
1114        but affects AD results (at machine truncation level): update output of
1115        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1116        and isomip (oad: 12.d).
1117    o pkg/generic_advdiff:
1118      - stop if doAB_onGtGs is set to FALSE but ignored
1119      - refine warning related to stability of tracer time-stepping
1120        regarding internal wave dynamics.
1121      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1122        on staggerTimeStep & implicitIntGravWave (will now get a warning
1123        if potentially unstable).
1124    o pkg/kl10:
1125      - add new pkg "kl10" for mixing due to internal wave breaking, from
1126        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1127        (contribution from Jody Klymak), tested in verification experiment
1128        verification/internal_wave/input.kl10/
1129    o isomip experiment:
1130      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1131        (input.htd) and update the output.
1132    o cd_code experiments:
1133      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1134        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1135        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1136        update the corresponding output.
1137    o pkg/seaice:
1138      - reduce the number of include files and store directives in
1139        S/R seaice_lsr_tridiagu/v
1140      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1141        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1142        get rid off one store directive (a TAF bug?)
1143      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1144        S/R seaice_lsr_tridiagv to change the loop range for consistency
1145      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1146      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1147        S/R seaice_lsr_tridiagu/v (requires update of
1148        offline_exf_seaice/input.dyn_jfnk)
1149    
1150    checkpoint65a (2014/07/27)
1151    o model/src:
1152      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1153        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1154        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1155        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1156    o model/src:
1157      - collect momentum forcing tendency into local 2-D array (passed as argument
1158        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1159        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1160        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1161      - collect T & S forcing tendency into local 2-D array (passed as argument to
1162        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1163        affects results at machine truncation level (e.g., ocean: if using
1164        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1165        correction due to vertical advection).
1166      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1167        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1168        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1169        obcs_ctrl (ad & fwd grd @ 12 & 7).
1170    o pkg/ptracers & diagnostics:
1171      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1172        title (to avoid some unexpected truncation); sort out ptracers diags units.
1173      - collect ptracer forcing tendency into local 2-D array (passed as argument
1174        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1175    
1176    checkpoint65 (2014/07/18)
1177    o pkg/fizhi:
1178      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1179        affects results at machine truncation level. Update output of experiments
1180        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1181    o pkg/seaice: more clean up
1182      - rename TAF common block tapes to be more consistent and remove
1183        unnecessary duplicates
1184      - add store directives to remove more recomputations, but use smaller
1185        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1186        The idea behind this flag is to reduce the memory footprint when the
1187        adjoint of the LSR is not required. As of now, defining the flag
1188        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1189        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1190        For experiment offline_exf_seaice, this means on a linux box with gfortran
1191        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1192        this experiment):
1193        > size mitgcmuv_ad
1194        text    data        bss     dec        hex
1195        5100659 1216  220458952  225560827  d71c8fb
1196        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1197        but only a moderate increase of 36% for global_ocean.cs32x15:
1198        text    data        bss     dec        hex
1199        6695027 1648 1014578664 1021275339 3cdf6ccb
1200        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1201      - note: there are still recomputations in global_ocean.cs32x15 and
1202        offline_exf_seaice and the gradient agreement changes (gets a
1203        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1204      - in general, the AD gradients still are wrong
1205    o OpenAD
1206      - clean up code_oad/ directories somewhat by moving files
1207        dontCompile, dontTransform, keepOriginal to OAD_support/
1208    o model/src:
1209      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1210        (not currently tested): add dissipation terms before NLFS rescaling of
1211        tendencies (previously done after).
1212    o pkg/diagnostics:
1213      - write stats-diags in ascii file with more digits (same as in monitor).
1214    o pkg/down_slope:
1215      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1216        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1217    o model/src:
1218      - new file "apply_forcing.F" containing all the code previously in
1219        external_forcing.F, but with new argument list: pass, as new argument,
1220        the current level tendency array to update (instead of a direct update
1221        of the common bloc array). Change the corresponding calls.
1222      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1223        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1224    o pkg/seaice/seaice_lsr, a little bit of clean up
1225      - rearrange some code blocks, so that now all calculations for
1226        setting up the right-hand-sides done within one single block
1227        (I find that easier to read and understand)
1228      - rearrange freedrift-code to reduce the number of ifdefs
1229      - adjust some indentations and comments
1230    
1231    checkpoint64z (2014/07/10)
1232    o model/src and several pkgs:
1233      - change argument list of all S/R called from external_forcing.F and
1234        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1235        to pass, as argument, the current level tendency array to update
1236        (instead of a direct update of the common bloc array).
1237      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1238      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1239    o pkg/seaice/seaice_lsr.F
1240      - always initialize local arrays in seaice_lsr_tridiagu/v
1241      - add more local tapes to seaice_lsr_tridiagu/v
1242      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1243        keep it in bi/bj loop; this seems to be essential
1244      - gradients are still wrong but only by 4-7 orders of magnitude
1245        instead of 15 orders of magnitude, lab_sea improves a little
1246    o pkg/seaice
1247      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1248        generates unnecessary code in seaice_lsr_ad
1249      - add more store directives in seaice_lsr to avoid unnecessary code
1250        in seaice_lsr_ad
1251      - exclude some residual computations in seaice_lsr when
1252        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1253        in seaice_lsr_ad
1254      - add more storing, a new tape (model/src/the_main_loop.F) and
1255        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1256        and klockey should be checked by a specialist)
1257      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1258        and update lab_sea after previous changes in pkg/seaice below
1259    o pkg/autodiff:
1260      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1261        viscFacInAd : run time parameters allowing for adjoint switches
1262        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1263    o pkg/ecco:
1264      - introduce cost_gencost_boxmean.F that computes a box mean
1265        temperature (for use in adjoint sensitivity studies).
1266    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1267    o pkg/mom_common/mom_calc_visc.F:
1268      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1269    o pkg/seaice/seaice_summary.F:
1270      - statement for SEAICEadjMODE now in autodiff_readparms.F
1271    o pkg/seaice:
1272      - remove some store directives and add new ones in an effort to get
1273        finally rid off the recomputation warnings. This is successful
1274        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1275        defined (i.e. no extensive recomputation warnings left), but there
1276        are still too many recomputations on the solver iteration level
1277      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1278      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1279        SEAICE_SIZE.h
1280      - add a store directive in S/R seaice_calc_viscosities
1281    o pkg/seaice (ITD code):
1282      - fix definition of Hlimit for multi-threaded case
1283      - use double precision arithmetic to compute Hlimit: this affects results;
1284        update output of experiment seaice_itd.
1285    o replace content of verification/seaice_itd
1286      - instead of a 1D column use the configuration of offline_exf_seaice
1287        to test the ice thickness distribution code with ridging
1288      - this is a first shot at this experiment
1289      - change of some defaults of ridging parameters SEAICEhStar (from
1290        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1291        and lot of new comments.
1292    
1293    checkpoint64y (2014/06/20)
1294    o pkg/seaice/seaice_reg_ridge.F:
1295      - modify the regularization of very small volumes of ice; only check
1296        total volume HEFF, and do not apply correction to individual ice
1297        classes because that leads to funny patterns in the heat and fw-fluxes
1298        into the ocean. Adjust seaice_itd/results/output.txt
1299      - replace nITD by SEAICE_multDim in loop-ranges
1300    o pkg/exf:
1301      - add code to process the case field period = -12. with UV interpolation.
1302      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1303        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1304    o verification/global_with_exf:
1305      - switch all fields period to -12. (was previously untested) in input/data.exf
1306        (but keep secondary test ".yearly" unchanged); update the reference output.
1307    o pkg/cal:
1308      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1309    o pkg/exf:
1310      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1311        to replace logical switch "exf_verbose"
1312      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1313    o pkg/sbo:
1314      - update from Katherine Quinn: evaluate mass directly from density and SSH
1315        (budget using Finite Volume method) instead of from bottom pressure.
1316      - allow testreport to collect few selected SBO output ; tested in exp.
1317        global_ocean.90x40x15 (after updating the results, to include SBO output).
1318      - fix some multi-threading issues (in output part).
1319    o model/src & most packages:
1320      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1321      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1322        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1323        "data.{pkg}" exist ; and leave the S/R (return) just after.
1324      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1325        + call LAND_READPARMS from packages_readparms.F
1326    o pkg/seaice:
1327      - remove code that resets useThSice in S/R seaice_readparms and
1328        replace it by a warning in S/R seaice_check
1329      - remove parameter MULTDIM, replace with nITD and runtime
1330        parameter SEAICE_multDim (still hard-wired to nITD if
1331        SEAICE_ITD is defined)
1332    
1333    checkpoint64x (2014/05/24)
1334    o verification/lab_sea:
1335      - update adjoint and TLM output following changes to pkg/salt_plume
1336      - un-do the update after putting back local recip_Cp in few places.
1337    o pkg/salt_plume: modifications by An Nguyen:
1338      - add capability to do brine rejection (salt-plume) as function of
1339        volume+tracers (instead of only salinity tracer).
1340      - conserve volume by exchanging volume from each kLev to above to
1341        accommodate in-coming brine volume
1342      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1343      - switch KPP surf buoyancy due to brine forcing to 3-d
1344        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1345      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1346      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1347        in East/West Arctic.
1348    o pkg/sbo:
1349      - incorporate modifications from Katherine Quinn to enable the use of sbo
1350        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1351        output for future testreport verification (unfinished).
1352    o pkg/atm_phys:
1353      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1354        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1355        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1356    o pkg/seaice
1357      seaice_calc_ice_strength.F: modify expression to avoid divisions
1358        (affects truncation)
1359      seaice_do_ridging.F: clean up the insectarium
1360      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1361      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1362      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1363      - add some debugging information and error messages (warnings)
1364    o model/src: modifications relatd to atmosphere p*:
1365      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1366      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1367        of vertical profile tRef in geopotential background and anomaly.
1368      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1369        and pkg/atm_phys.
1370      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1371        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1372    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1373    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1374        not used right now, but can be used in BGC packages to fix conservation.
1375    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1376        other packages too.
1377    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1378        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1379    o model/src:
1380      - since we have several heat capacity (even in model/src), define "recip_Cp"
1381        as local variable (no longer in common block) to avoid any confusion.
1382      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1383    o pkg/exf:
1384      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1385        air density as function of air Temp, Humidity and atm pressure.
1386    
1387    checkpoint64w (2014/05/02)
1388    o verification:
1389      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1390        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1391        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1392        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1393        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1394    o model/src: for atmosphere in p* coords:
1395      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1396      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1397        but not yet activated.
1398    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1399      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1400      - this changes the results (but not for any verification experiment, because
1401        none tests this), but avoids having an extra field in the restart files
1402    o pkg/seaice: remove global variable TICE (not needed)
1403      - replace by TICES or local variable where necessary (cost_seaice_test,
1404        seaice_diagnostics_state)
1405      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1406      - use specific read/write routines for reading and writing individual leves
1407        of a multilevel field
1408    o pkg/ctrl & model/inc:
1409      - move additional anomaly fields of control vars (related to options:
1410         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1411        from DYNVARS.h into new header file: CTRL_FIELDS.h
1412    o pkg/seaice: some small modifications to the ridging code
1413      - make fw2ObyRidge a global variable and add the freshwater flux to
1414        seaice_growth
1415      - pass actual thickness from seaice_prepare_ridging, so that it is
1416        computed only in one place and compute it in the same way as in
1417        seaice_growth
1418      - initialise more fields in seaice_do_ridging that where cause floating
1419        point exceptions over land
1420    o pkg/seaice: preparations for ridging code and first real ridging code
1421      - move most of "PART 1" of S/R seaice_growth into a new and separate
1422        S/R seaice_reg_ridge that will both regularize the state variable after
1423        advection call the actual ridging routine;
1424      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1425        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1426      - remove ridging code from seaice_advdiff
1427      - clean up remaining part 1 of seaice_growth in an attempt to make it
1428        more readable (this is probably subjective)
1429      - call seaice_itd_redist once in the initialisation phase to have the initial
1430        conditions in the correct category
1431      - finally: add new ridging routine for ITD code
1432    
1433    checkpoint64v (2014/04/11)
1434    o pkg/ecco:
1435      - add runtime parameters mdt[start,end]date[1,2]
1436      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1437    o pkg/seaice:
1438      - make deltaC a global variable, so that it can be used in ridging code
1439      - first step towards ridging: introduce new routines that compute
1440        ice strength based on ridging parameters
1441      - add diagnostic for HSNOWITD
1442      - add opnWtrFrac as a global variable (required for ridging scheme)
1443    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1444      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1445        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1446    o verification/hs94.1x64x5:
1447      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1448      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1449    o autodiff:
1450      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1451        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1452        For now, only in pkgs used in verification/hs94.1x64x5.
1453      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1454        which are specific to TAF/TAMC).
1455      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1456        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1457        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1458      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1459        building mitgcmuv_ad (make adAll).
1460    o pkg/ecco:
1461      - cost_gencost_seaicev4.F:
1462         reformulate proxy cost as function of sst and local param SEAICE_freeze
1463         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1464      - add stop statement if old names siv4-[sst,vol] are used
1465      - add snapshots + cost reports for atmospheric longwave
1466      - remove factor 0.1 in front of wtau[u,v]
1467      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1468         ALLOW_TMI_SST_COST_CONTRIBUTION
1469    o pkg/atm_phys:
1470      - add some diagnostics for Short-wave and for convection S/R.
1471    o pkg/seaice/seaice_growth:
1472      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1473        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1474      - rearrange loop order for better vector code in the same code block
1475      - rewrite the floeDiameter formula to have fewer divisions
1476      -  (miraculously) none of this changes the results of seaice_itd
1477    o pkg/smooth:
1478      - move param smooth2Ddiffnbt to pkg/ecco
1479    o pkg/salt_plume:
1480      - salt_plume_frac.F:
1481         clean up local param names
1482         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1483    o pkg/rw:
1484      - add RS version of S/R READ_MFLDS_LEV.
1485    o pkg/streamice:
1486      - fix the restart test by writing/reading pickup_streamice files.
1487    o pkg/seaice:
1488      - refine checks for jfnk-related parameters
1489      - comment out if statement with SEAICEuseIMEX parameter as long as there
1490        is no IMEX code to avoid confusion and surprises
1491    
1492    checkpoint64u (2014/03/07)
1493    o verification/MLAdjust:
1494      - rename secondary test suffix:
1495         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1496         0.leithD -> AhFlxF  + switch to flux-form
1497         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1498         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1499    o pkg/mom_vecinv:
1500      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1501        to be before mom_calc_visc.F)
1502      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1503      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1504        this is simpler for the adjoint and for diagnostics.
1505    o model/src + pkg/momentum:
1506      - add input files for  2-D additional Western and Southern cell-edge wall
1507         (e.g., to add "thin-wall" where it is =1).
1508      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1509        using 2nd hFacZ that is computed from initial (fix domain) hFac
1510      - known limitations of thin wall implementation: not yet coded for sigma
1511        coords; not working with CD-scheme neither.
1512    o pkg/seaice:
1513      - rename recently introduced parameters from (wrong name) AB to
1514        BDF (backward difference time discretisation)
1515      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1516    o tools/adjoint_options:
1517      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1518    
1519    checkpoint64t (2014/02/01)
1520    o pkg/ecco
1521      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1522        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1523      - replace hard-coded record number and period which only work for monthly
1524        with read-in runtime param that works for other periods (month,day,year)
1525    o pkg/thsice
1526      - corrected store directive fixes thsice adjoint gradient checks
1527    o genmake2 & testreport:
1528      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1529        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1530        Update testreport accordingly. No need to set "export OPENAD=true"
1531        in adjoint_options/adjoint_oad anymore (will be removed later).
1532    o pkg/shelfice:
1533      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1534        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1535        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1536    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1537      - Changes to make GENARR more modular (i.e. invisible if not used)
1538    o model/src/temp_integrate.F and salt_integrate.F
1539      - re-include store directives that were removed on Dec 27th.
1540    o model/src/external_forcing_surf.F
1541      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1542        seaice_model in the adjoint that is problematic when seaice_model is
1543        turned off in the adjoint. The resolved issue dated back to July when
1544        EXTERNAL_FORCING_SURF call was moved.
1545        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1546    o pkg/exf/exf_check.F
1547      - fix a small bug again (originally found by Wentao Liu, now found again)
1548      - streamline error output
1549    o pkg/streamice and aim_v23:
1550      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1551        Apple's /usr/bin/cpp knows what to do:
1552        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1553        Target: x86_64-apple-darwin13.0.0
1554    
1555    checkpoint64s (2014/01/05)
1556    o tools/adjoint_options:
1557      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1558        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1559    o model/src:
1560      - remove some unnecessary TAF storage directives in forward_step.F and
1561        in dynamics.F (note: not always removed by TAF, e.g., double storage
1562        of kappaRU,kappaRV in former version of dynamics.F).
1563    o model/src & pkg/ptracers:
1564      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1565        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1566        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1567      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1568      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1569      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1570    o useSingleCpuInput separates single-CPU input from single-CPU output;
1571        for now only implemented for in exf_interp_read.F
1572    o verification/advect_xy:
1573      - fix missing EXCH call in local version of ini_salt.F and update output.
1574    o momentum diagnostics:
1575      - fix which deltaT is used in Total-Tendency diagnostics.
1576      - fix typo in diagnostics for momentum tendency from AB.
1577    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1578        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1579    
1580    checkpoint64r (2013/12/08)
1581    o verification/*/results:
1582      - Update reference output of experiments that were passing with just 13 digits
1583         (make it easier to detect future changes in results)
1584    o model/src & pkg/ptracers:
1585      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1586        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1587        to inside ptracers_integrate.F ; remove ptracers_advection.F
1588    o coupling interface pkgs:
1589        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1590      - change the config check to test the agreement of Ocean Depth
1591        with ATM land/sea mask (instead of ATM orography);
1592      - send to coupler the number of coupler time-steps to do for this run:
1593        this allows to check for consistency and don't need anymore to be
1594        specified in parameter file "data";
1595      in coupler:
1596      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1597      - improve report to log-file of config setting (pass log-file unit to few S/R)
1598    o pkg/compon_communic:
1599      - add coupling send/receive for non-tiled integer vector;
1600      - add S/R to check and stop if any proc has an error (similar to
1601        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1602    o pkg/exch2:
1603      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1604        through list of all tiles my proc owns.
1605    o model/src:
1606      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1607        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1608        calling S/R); this affects AD results at machine truncation level:
1609        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1610        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1611    o tools/build_options:
1612      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1613    o coupling interface pkgs:
1614        [compon_communic, atm_compon_interf & ocn_compon_interf]
1615      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1616        to each S/R that needs it; remove un-used variables.
1617      - change component tile registration (cpl_register.F in both compon_interf
1618        and mitcomponent_tile_register.F) to pass the full list of tiles
1619        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1620      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1621        towards coupler global array (unless W2_useE2ioLayOut=F):
1622         a) can now use different tiling between atm & ocn comp.
1623         b) no needs to modify the run-Off map when changing tiling (was needed
1624            even if using the same tiling between atm & ocn).
1625         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1626            full land tiles); not yet tested.
1627      - check for valid mapping from comp. tile to coupler global array
1628      - improve report of tile registration results to log file.
1629    o pkg/exch2:
1630      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1631        tile-registration (CPL_REGISTER);
1632      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1633        store the local bi,bj indices of each tile;
1634      - also print bi,bj in local report to log file;
1635      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1636        Jun 2009 modif of pkg/exch2).
1637    o testing on baudelaire:
1638      - run 2 tests at a time: no significant slow down (since enough cpu) and
1639        get the full set of test done earlier
1640      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1641    o model/src/thermodynamics.F and routines called from it:
1642      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1643        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1644        velocity (outp) by adding bolus velocity.
1645      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1646        mass transport from velocity + lateral grid cell area
1647      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1648      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1649     in thermodynamics.F
1650      - remove k from thermodynamics.F and move it to temp_integrate.F
1651        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1652        loop).
1653      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1654        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1655        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1656        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1657      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1658        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1659        tutorial_tracer_adjsens (+ TLM output).
1660    o tools/OAD_support and (verification/*/) code_oad:
1661      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1662        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1663      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1664        version (closer to model/inc/CPP_OPTIONS.h).
1665    o model/src:
1666      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1667        retired list of parameters (routine FREEZE has been replace by surface
1668        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1669    o pkg/gmredi:
1670      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1671        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1672      - update output of FWD experiments: front_relax.bvp,
1673        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1674    
1675    checkpoint64q (2013/11/17)
1676    o verification:
1677      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1678        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1679      - generate new output (growth & melt) for seaice_itd experiment after
1680        updating the input pickup_seaice files (previously wrong).
1681    o pkg/cost:
1682      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1683        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1684        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1685          cannot be applied to var in common block).
1686        o allows to get results independent of tile-per-proc setting (if using
1687          slower GLOBAL_SUM_SEND_RECV option).
1688      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1689        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1690        forward gradients: update output).
1691      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1692        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1693    o pkg/mom_common:
1694      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1695        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1696        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1697        ensure that all field value that are used are set.
1698    o tutorial_deep_convection (smag3d):
1699      - add missing scaling in mom_calc_smag_3d.F;
1700      - set smag3D_coeff in input.smag3d such that results do not change.
1701    o pkg/dic:
1702      - change dic_cost.F to compute cost on each tile first and then apply
1703        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1704        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1705      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1706    o eesupp/src & pkg/mdsio:
1707      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1708        (from pkg/mdsio) since they are no longer used for tape IO.
1709      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1710        (+ keep a copy in pkg/atm_ocn_coupler).
1711    o verification/isomip:
1712      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1713    o tools/build_options:
1714      - optfile linux_amd64_ifort11, fast (no ieee) case:
1715        to get a working restart for all experiments, add "-fp-model source"
1716        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1717    
1718    checkpoint64p (2013/10/20)
1719    o pkg/autodiff:
1720      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1721        criteria, return to simple (default) tape IO format.
1722    o pkg/mdsio (+ eesupp/src):
1723      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1724        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1725      - fix globalFile and singleCpuIO options using simpler global mapping.
1726      - new pairs of scatter/gather vector S/R (one for each type, generated from
1727        template) corresponding to simpler global mapping.
1728      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1729        to globalFile when parameter globalFiles is set to True.
1730      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1731    o pkg/autodiff:
1732      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1733        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
1734        missing, just add a STOP if array type do not match.
1735    o pkg/exf:
1736      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
1737         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
1738         and rename array obsSIce to exf_iceFraction.
1739    o tutorial_deep_convection:
1740      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
1741        for now all in this exp. code dir.
1742      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
1743        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
1744    o eesupp/src:
1745      - added SINGLE_DISK_IO option because reading of parameter files on
1746        very large number of processors did not work with existing set-up
1747    
1748    checkpoint64o (2013/09/25)
1749    o pkg/atm_phys & atm_compon_interf:
1750      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
1751    o tools/build_options:
1752      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
1753        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
1754        remove CPP setting (was identical to genmake2 default).
1755    o pkg/gmredi & model/src: Some updating and work done on the residual model.
1756      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
1757      - fixed up the calculation of the eddy stress and how it is added to the
1758        external forcing via taueddy_external_forcing.F
1759      - at the moment, it is very experimental and only works with the variable eddy
1760        diffusivity calculated in gmredi_k3d.F
1761    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
1762        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
1763    o testreport (& tools/do_tst_2+2):
1764      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
1765    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
1766      - remove CPP='cpp -traditional -P' (this is genmake2 default)
1767      - add switch (for big setups) to use 'medium' memory-model (but leave it
1768        commented out for now). Note: needed with FC 19 to compile big setups.
1769    o pkg/atm_compon_interf:
1770      - regroup per field origin (model & pkgs) the coupling storage routines
1771         (which accumalate in time each coupling field)
1772      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
1773        update accordingly + simplify aim_do_physics.F
1774    
1775    checkpoint64n (2013/08/26)
1776    o pkg/bbl:
1777      - update formulation to reduce dispersion of tracer properties in bbl
1778      - replaced horizontal and vertical transport parameters with velocities
1779      - changes results for verification/global_with_exf.yearly
1780    o verification/halfpipe_streamice:
1781      - change to matrix construction; update both Fwd & AD output.
1782    o verification/tutorial_tracer_adjsens:
1783      - OpenAD test: switch to vector-invariant momentum since fluxform with
1784        rStar causes problems with OpenAD; update output.
1785    o tools:
1786      - genmake2: define a common prefix for all temp-file names ; move them
1787        to local /tmp disk (but would be easy to move them back);
1788      - xmakedepend: apply the same switch for temp-files.
1789    o pkg/offline:
1790      - changes for use with rStar (NLFS): assume that we continue to provide
1791        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
1792        output files) and apply r* scaling at each time-step (function of the time
1793        varying Eta field); use normal pickup files (needed for restart with NLFS).
1794    o adjoint with OpenAD:
1795      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
1796        package openad.  This package has to be compiled for all runs with OpenAD
1797        instead of specifying code_oad_all as a modification directory.
1798      - link the fortran templates from tools/OAD_support to the build directory
1799        for preprocessing to avoid conflicts between different setups compiled
1800        simultaneously and simplify cleanup.
1801    o pkg/exf:
1802      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
1803        main model or other pkgs are exchanged in EXF_MAPFIELDS).
1804    o model/src:
1805      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
1806        (similar to do_fields_blocking_exchanges.F).
1807    o tools/genmake2:
1808      - remove TAF output src code just before calling staf (when not doing a fresh
1809        built, will stop if things go wrong with staf).
1810      - fix target "adobj" (left from TAF version-2 transition)
1811    o pkg/diagnostics:
1812      - add a parameter to track the status of pkg/diagnostics activation;
1813        this replace/extend the use of logical param "settingDiags" (to check
1814        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
1815        New S/R to print error message and stop when pkgStatus is not right.
1816      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
1817    
1818    checkpoint64m (2013/08/13)
1819    o model/inc:
1820      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
1821        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
1822    o pkg/kpp & aim_v23:
1823      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1824    o pkg/seaice:
1825      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
1826        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
1827      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
1828    o eesupp/src:
1829      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
1830        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
1831    o switch to TAF version-2:
1832      - add flow directives to "freeze" naming convention for ad-routines that
1833        are used in I/O routines of adjoint state and associated common blocks
1834        that are used in adcommon.h (backward compatible with version-1)
1835      - update all ad-optfiles (in tools/adjoint_options + few local to some
1836        verification exp) to switch to latest TAF version (currently 2.5.5);
1837        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
1838        out except for diva).
1839      - the major change with TAF version-2 is that both the differentiated
1840        routines and the forward routines (new) are returned as part of the TAF
1841        output source code. Update genmake2 accordingly.
1842      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
1843        with version-2 when compared to TLM or FWD gradient); other experiments
1844        output show minor changes (machine truncation level); update the few AD &
1845        TLM output with 12 matching digits only (some prior to version-2 switch).
1846    
1847    checkpoint64l (2013/08/05)
1848    o model/src:
1849      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
1850      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
1851        when using TAF but only if using OpenAD.
1852    o pkg/mom_common+fluxform+vecinv:
1853      - always set horiz. viscosity arrays to background value before calling
1854        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
1855        only when using variable horiz. viscosity (useVariableVisc=T);
1856      - simplify mom_vecinv.F (only 1 block for momViscosity).
1857    o pkg/mom_common: variable horiz. viscosity in NH code
1858      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
1859        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
1860      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
1861        useBiharmonicVisc & useVariableVisc.
1862      - fix old bug (already in 1rst implementation of variable horizontal viscosity
1863        in calc_gw.F, version 1.27, 2006/06/20):
1864        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
1865        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
1866      - change background horiz viscosity in vertical momentum (gW) to always be
1867        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
1868        any type of variable viscosity, e.g., viscAh/4Grid)
1869      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
1870        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
1871        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
1872        default viscAh,viscA4 is zero).
1873    o model/src:
1874      - extend length of drC & recip_drC from Nr to Nr+1.
1875  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
1876    - genmake2: do not create local ./mpi_headers dir when no file to copy into.    - genmake2: do not create local ./mpi_headers dir when no file to copy into.
1877    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
