4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - new file "apply_forcing.F" containing all the code previously in
9        external_forcing.F, but with new argument list: pass, as new argument,
10        the current level tendency array to update (instead of a direct update
11        of the common bloc array). Change the corresponding calls.
12      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
13        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
14    o pkg/seaice/seaice_lsr, a little bit of clean up
15      - rearrange some code blocks, so that now all calculations for
16        setting up the right-hand-sides done within one single block
17        (I find that easier to read and understand)
18      - rearrange freedrift-code to reduce the number of ifdefs
19      - adjust some indentations and comments
20    
21    checkpoint64z (2014/07/10)
22    o model/src and several pkgs:
23      - change argument list of all S/R called from external_forcing.F and
24        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
25        to pass, as argument, the current level tendency array to update
26        (instead of a direct update of the common bloc array).
27      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
28      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
29    o pkg/seaice/seaice_lsr.F
30      - always initialize local arrays in seaice_lsr_tridiagu/v
31      - add more local tapes to seaice_lsr_tridiagu/v
32      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
33        keep it in bi/bj loop; this seems to be essential
34      - gradients are still wrong but only by 4-7 orders of magnitude
35        instead of 15 orders of magnitude, lab_sea improves a little
36    o pkg/seaice
37      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
38        generates unnecessary code in seaice_lsr_ad
39      - add more store directives in seaice_lsr to avoid unnecessary code
40        in seaice_lsr_ad
41      - exclude some residual computations in seaice_lsr when
42        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
43        in seaice_lsr_ad
44      - add more storing, a new tape (model/src/the_main_loop.F) and
45        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
46        and klockey should be checked by a specialist)
47      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
48        and update lab_sea after previous changes in pkg/seaice below
49    o pkg/autodiff:
50      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
51        viscFacInAd : run time parameters allowing for adjoint switches
52        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
53    o pkg/ecco:
54      - introduce cost_gencost_boxmean.F that computes a box mean
55        temperature (for use in adjoint sensitivity studies).
56    o model/src/set_defaults.F : initialize viscFacAdj to 1.
57    o pkg/mom_common/mom_calc_visc.F:
58      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
59    o pkg/seaice/seaice_summary.F:
60      - statement for SEAICEadjMODE now in autodiff_readparms.F
61    o pkg/seaice:
62      - remove some store directives and add new ones in an effort to get
63        finally rid off the recomputation warnings. This is successful
64        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
65        defined (i.e. no extensive recomputation warnings left), but there
66        are still too many recomputations on the solver iteration level
67      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
68      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
69        SEAICE_SIZE.h
70      - add a store directive in S/R seaice_calc_viscosities
71    o pkg/seaice (ITD code):
72      - fix definition of Hlimit for multi-threaded case
73      - use double precision arithmetic to compute Hlimit: this affects results;
74        update output of experiment seaice_itd.
75    o replace content of verification/seaice_itd
76      - instead of a 1D column use the configuration of offline_exf_seaice
77        to test the ice thickness distribution code with ridging
78      - this is a first shot at this experiment
79      - change of some defaults of ridging parameters SEAICEhStar (from
80        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
81        and lot of new comments.
82    
83    checkpoint64y (2014/06/20)
84    o pkg/seaice/seaice_reg_ridge.F:
85      - modify the regularization of very small volumes of ice; only check
86        total volume HEFF, and do not apply correction to individual ice
87        classes because that leads to funny patterns in the heat and fw-fluxes
88        into the ocean. Adjust seaice_itd/results/output.txt
89      - replace nITD by SEAICE_multDim in loop-ranges
90    o pkg/exf:
91      - add code to process the case field period = -12. with UV interpolation.
92      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
93        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
94    o verification/global_with_exf:
95      - switch all fields period to -12. (was previously untested) in input/data.exf
96        (but keep secondary test ".yearly" unchanged); update the reference output.
97    o pkg/cal:
98      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
99    o pkg/exf:
100      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
101        to replace logical switch "exf_verbose"
102      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
103    o pkg/sbo:
104      - update from Katherine Quinn: evaluate mass directly from density and SSH
105        (budget using Finite Volume method) instead of from bottom pressure.
106      - allow testreport to collect few selected SBO output ; tested in exp.
107        global_ocean.90x40x15 (after updating the results, to include SBO output).
108      - fix some multi-threading issues (in output part).
109    o model/src & most packages:
110      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
111      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
112        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
113        "data.{pkg}" exist ; and leave the S/R (return) just after.
114      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
115        + call LAND_READPARMS from packages_readparms.F
116    o pkg/seaice:
117      - remove code that resets useThSice in S/R seaice_readparms and
118        replace it by a warning in S/R seaice_check
119      - remove parameter MULTDIM, replace with nITD and runtime
120        parameter SEAICE_multDim (still hard-wired to nITD if
121        SEAICE_ITD is defined)
122    
123    checkpoint64x (2014/05/24)
124    o verification/lab_sea:
125      - update adjoint and TLM output following changes to pkg/salt_plume
126      - un-do the update after putting back local recip_Cp in few places.
127    o pkg/salt_plume: modifications by An Nguyen:
128      - add capability to do brine rejection (salt-plume) as function of
129        volume+tracers (instead of only salinity tracer).
130      - conserve volume by exchanging volume from each kLev to above to
131        accommodate in-coming brine volume
132      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
133      - switch KPP surf buoyancy due to brine forcing to 3-d
134        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
135      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
136      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
137        in East/West Arctic.
138    o pkg/sbo:
139      - incorporate modifications from Katherine Quinn to enable the use of sbo
140        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
141        output for future testreport verification (unfinished).
142    o pkg/atm_phys:
143      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
144        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
145        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
146    o pkg/seaice
147      seaice_calc_ice_strength.F: modify expression to avoid divisions
148        (affects truncation)
149      seaice_do_ridging.F: clean up the insectarium
150      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
151      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
152      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
153      - add some debugging information and error messages (warnings)
154    o model/src: modifications relatd to atmosphere p*:
155      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
156      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
157        of vertical profile tRef in geopotential background and anomaly.
158      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
159        and pkg/atm_phys.
160      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
161        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
162    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
163    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
164        not used right now, but can be used in BGC packages to fix conservation.
165    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
166        other packages too.
167    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
168        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
169    o model/src:
170      - since we have several heat capacity (even in model/src), define "recip_Cp"
171        as local variable (no longer in common block) to avoid any confusion.
172      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
173    o pkg/exf:
174      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
175        air density as function of air Temp, Humidity and atm pressure.
176    
177    checkpoint64w (2014/05/02)
178    o verification:
179      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
180        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
181        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
182        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
183        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
184    o model/src: for atmosphere in p* coords:
185      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
186      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
187        but not yet activated.
188    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
189      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
190      - this changes the results (but not for any verification experiment, because
191        none tests this), but avoids having an extra field in the restart files
192    o pkg/seaice: remove global variable TICE (not needed)
193      - replace by TICES or local variable where necessary (cost_seaice_test,
194        seaice_diagnostics_state)
195      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
196      - use specific read/write routines for reading and writing individual leves
197        of a multilevel field
198    o pkg/ctrl & model/inc:
199      - move additional anomaly fields of control vars (related to options:
200         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
201        from DYNVARS.h into new header file: CTRL_FIELDS.h
202    o pkg/seaice: some small modifications to the ridging code
203      - make fw2ObyRidge a global variable and add the freshwater flux to
204        seaice_growth
205      - pass actual thickness from seaice_prepare_ridging, so that it is
206        computed only in one place and compute it in the same way as in
207        seaice_growth
208      - initialise more fields in seaice_do_ridging that where cause floating
209        point exceptions over land
210    o pkg/seaice: preparations for ridging code and first real ridging code
211      - move most of "PART 1" of S/R seaice_growth into a new and separate
212        S/R seaice_reg_ridge that will both regularize the state variable after
213        advection call the actual ridging routine;
214      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
215        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
216      - remove ridging code from seaice_advdiff
217      - clean up remaining part 1 of seaice_growth in an attempt to make it
218        more readable (this is probably subjective)
219      - call seaice_itd_redist once in the initialisation phase to have the initial
220        conditions in the correct category
221      - finally: add new ridging routine for ITD code
222    
223    checkpoint64v (2014/04/11)
224    o pkg/ecco:
225      - add runtime parameters mdt[start,end]date[1,2]
226      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
227    o pkg/seaice:
228      - make deltaC a global variable, so that it can be used in ridging code
229      - first step towards ridging: introduce new routines that compute
230        ice strength based on ridging parameters
231      - add diagnostic for HSNOWITD
232      - add opnWtrFrac as a global variable (required for ridging scheme)
233    o pkg/salt_plume + pkg/seaice/seaice_growth.F
234      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
235        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
236    o verification/hs94.1x64x5:
237      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
238      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
239    o autodiff:
240      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
241        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
242        For now, only in pkgs used in verification/hs94.1x64x5.
243      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
244        which are specific to TAF/TAMC).
245      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
246        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
247        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
248      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
249        building mitgcmuv_ad (make adAll).
250    o pkg/ecco:
251      - cost_gencost_seaicev4.F:
252         reformulate proxy cost as function of sst and local param SEAICE_freeze
253         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
254      - add stop statement if old names siv4-[sst,vol] are used
255      - add snapshots + cost reports for atmospheric longwave
256      - remove factor 0.1 in front of wtau[u,v]
257      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
258         ALLOW_TMI_SST_COST_CONTRIBUTION
259    o pkg/atm_phys:
260      - add some diagnostics for Short-wave and for convection S/R.
261    o pkg/seaice/seaice_growth:
262      - fix a bug in the lateral melt parameterization for SEAICE_ITD
263        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
264      - rearrange loop order for better vector code in the same code block
265      - rewrite the floeDiameter formula to have fewer divisions
266      -  (miraculously) none of this changes the results of seaice_itd
267    o pkg/smooth:
268      - move param smooth2Ddiffnbt to pkg/ecco
269    o pkg/salt_plume:
270      - salt_plume_frac.F:
271         clean up local param names
272         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
273    o pkg/rw:
274      - add RS version of S/R READ_MFLDS_LEV.
275    o pkg/streamice:
276      - fix the restart test by writing/reading pickup_streamice files.
277    o pkg/seaice:
278      - refine checks for jfnk-related parameters
279      - comment out if statement with SEAICEuseIMEX parameter as long as there
280        is no IMEX code to avoid confusion and surprises
281    
282    checkpoint64u (2014/03/07)
283    o verification/MLAdjust:
284      - rename secondary test suffix:
285         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
286         0.leithD -> AhFlxF  + switch to flux-form
287         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
288         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
289    o pkg/mom_vecinv:
290      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
291        to be before mom_calc_visc.F)
292      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
293      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
294        this is simpler for the adjoint and for diagnostics.
295    o model/src + pkg/momentum:
296      - add input files for  2-D additional Western and Southern cell-edge wall
297         (e.g., to add "thin-wall" where it is =1).
298      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
299        using 2nd hFacZ that is computed from initial (fix domain) hFac
300      - known limitations of thin wall implementation: not yet coded for sigma
301        coords; not working with CD-scheme neither.
302    o pkg/seaice:
303      - rename recently introduced parameters from (wrong name) AB to
304        BDF (backward difference time discretisation)
305      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
306    o tools/adjoint_options:
307      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
308    
309    checkpoint64t (2014/02/01)
310    o pkg/ecco
311      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
312        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
313      - replace hard-coded record number and period which only work for monthly
314        with read-in runtime param that works for other periods (month,day,year)
315    o pkg/thsice
316      - corrected store directive fixes thsice adjoint gradient checks
317    o genmake2 & testreport:
318      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
319        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
320        Update testreport accordingly. No need to set "export OPENAD=true"
321        in adjoint_options/adjoint_oad anymore (will be removed later).
322    o pkg/shelfice:
323      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
324        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
325        so that surface forcing applies to k=kSurf if using pkg/shelfice.
326    o pkg/ctrl, pkg/grdchk, pkg/ecco:
327      - Changes to make GENARR more modular (i.e. invisible if not used)
328    o model/src/temp_integrate.F and salt_integrate.F
329      - re-include store directives that were removed on Dec 27th.
330    o model/src/external_forcing_surf.F
331      - add storage directives for EmPmR and PmEpR to avoid recomputation of
332        seaice_model in the adjoint that is problematic when seaice_model is
333        turned off in the adjoint. The resolved issue dated back to July when
334        EXTERNAL_FORCING_SURF call was moved.
335        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
336    o pkg/exf/exf_check.F
337      - fix a small bug again (originally found by Wentao Liu, now found again)
338      - streamline error output
339    o pkg/streamice and aim_v23:
340      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
341        Apple's /usr/bin/cpp knows what to do:
342        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
343        Target: x86_64-apple-darwin13.0.0
344    
345    checkpoint64s (2014/01/05)
346    o tools/adjoint_options:
347      - switch to fastopt.net TAF server (instead of default fastopt.de) for
348        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
349    o model/src:
350      - remove some unnecessary TAF storage directives in forward_step.F and
351        in dynamics.F (note: not always removed by TAF, e.g., double storage
352        of kappaRU,kappaRV in former version of dynamics.F).
353    o model/src & pkg/ptracers:
354      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
355        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
356        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
357      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
358      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
359      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
360    o useSingleCpuInput separates single-CPU input from single-CPU output;
361        for now only implemented for in exf_interp_read.F
362    o verification/advect_xy:
363      - fix missing EXCH call in local version of ini_salt.F and update output.
364    o momentum diagnostics:
365      - fix which deltaT is used in Total-Tendency diagnostics.
366      - fix typo in diagnostics for momentum tendency from AB.
367    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
368        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
369    
370    checkpoint64r (2013/12/08)
371    o verification/*/results:
372      - Update reference output of experiments that were passing with just 13 digits
373         (make it easier to detect future changes in results)
374    o model/src & pkg/ptracers:
375      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
376        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
377        to inside ptracers_integrate.F ; remove ptracers_advection.F
378    o coupling interface pkgs:
379        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
380      - change the config check to test the agreement of Ocean Depth
381        with ATM land/sea mask (instead of ATM orography);
382      - send to coupler the number of coupler time-steps to do for this run:
383        this allows to check for consistency and don't need anymore to be
384        specified in parameter file "data";
385      in coupler:
386      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
387      - improve report to log-file of config setting (pass log-file unit to few S/R)
388    o pkg/compon_communic:
389      - add coupling send/receive for non-tiled integer vector;
390      - add S/R to check and stop if any proc has an error (similar to
391        eesupp/src/stop_if_error.F but single thread and across Comm_World).
392    o pkg/exch2:
393      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
394        through list of all tiles my proc owns.
395    o model/src:
396      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
397        from rTrans) to simplify dependencies (no need to store rTrans anymore in
398        calling S/R); this affects AD results at machine truncation level:
399        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
400        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
401    o tools/build_options:
402      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
403    o coupling interface pkgs:
404        [compon_communic, atm_compon_interf & ocn_compon_interf]
405      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
406        to each S/R that needs it; remove un-used variables.
407      - change component tile registration (cpl_register.F in both compon_interf
408        and mitcomponent_tile_register.F) to pass the full list of tiles
409        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
410      - with pkg/exch2: adopt the same convention used for I/O to define mapping
411        towards coupler global array (unless W2_useE2ioLayOut=F):
412         a) can now use different tiling between atm & ocn comp.
413         b) no needs to modify the run-Off map when changing tiling (was needed
414            even if using the same tiling between atm & ocn).
415         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
416            full land tiles); not yet tested.
417      - check for valid mapping from comp. tile to coupler global array
418      - improve report of tile registration results to log file.
419    o pkg/exch2:
420      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
421        tile-registration (CPL_REGISTER);
422      - activate (un-comment) definition and setting of "W2_tileIndex" list to
423        store the local bi,bj indices of each tile;
424      - also print bi,bj in local report to log file;
425      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
426        Jun 2009 modif of pkg/exch2).
427    o testing on baudelaire:
428      - run 2 tests at a time: no significant slow down (since enough cpu) and
429        get the full set of test done earlier
430      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
431    o model/src/thermodynamics.F and routines called from it:
432      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
433        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
434        velocity (outp) by adding bolus velocity.
435      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
436        mass transport from velocity + lateral grid cell area
437      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
438      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
439     in thermodynamics.F
440      - remove k from thermodynamics.F and move it to temp_integrate.F
441        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
442        loop).
443      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
444        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
445        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
446        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
447      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
448        global_ocean.90x40x15, tutorial_global_oce_biogeo and
449        tutorial_tracer_adjsens (+ TLM output).
450    o tools/OAD_support and (verification/*/) code_oad:
451      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
452        module conversion ; remove unneeded CPP_EEOPTIONS.h.
453      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
454        version (closer to model/inc/CPP_OPTIONS.h).
455    o model/src:
456      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
457        retired list of parameters (routine FREEZE has been replace by surface
458        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
459    o pkg/gmredi:
460      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
461        velocity (same scheme but affects machine truncation) for GM_AdvForm.
462      - update output of FWD experiments: front_relax.bvp,
463        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
464    
465    checkpoint64q (2013/11/17)
466    o verification:
467      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
468        tutorial_global_oce_biogeo and global_ocean.90x40x15.
469      - generate new output (growth & melt) for seaice_itd experiment after
470        updating the input pickup_seaice files (previously wrong).
471    o pkg/cost:
472      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
473        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
474        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
475          cannot be applied to var in common block).
476        o allows to get results independent of tile-per-proc setting (if using
477          slower GLOBAL_SUM_SEND_RECV option).
478      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
479        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
480        forward gradients: update output).
481      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
482        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
483    o pkg/mom_common:
484      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
485        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
486        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
487        ensure that all field value that are used are set.
488    o tutorial_deep_convection (smag3d):
489      - add missing scaling in mom_calc_smag_3d.F;
490      - set smag3D_coeff in input.smag3d such that results do not change.
491    o pkg/dic:
492      - change dic_cost.F to compute cost on each tile first and then apply
493        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
494        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
495      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
496    o eesupp/src & pkg/mdsio:
497      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
498        (from pkg/mdsio) since they are no longer used for tape IO.
499      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
500        (+ keep a copy in pkg/atm_ocn_coupler).
501    o verification/isomip:
502      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
503    o tools/build_options:
504      - optfile linux_amd64_ifort11, fast (no ieee) case:
505        to get a working restart for all experiments, add "-fp-model source"
506        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
507    
508    checkpoint64p (2013/10/20)
509    o pkg/autodiff:
510      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
511        criteria, return to simple (default) tape IO format.
512    o pkg/mdsio (+ eesupp/src):
513      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
514        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
515      - fix globalFile and singleCpuIO options using simpler global mapping.
516      - new pairs of scatter/gather vector S/R (one for each type, generated from
517        template) corresponding to simpler global mapping.
518      - adread_write.F: switch to new S/R (but leave old calls commented) and write
519        to globalFile when parameter globalFiles is set to True.
520      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
521    o pkg/autodiff:
522      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
523        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
524        missing, just add a STOP if array type do not match.
525    o pkg/exf:
526      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
527         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
528         and rename array obsSIce to exf_iceFraction.
529    o tutorial_deep_convection:
530      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
531        for now all in this exp. code dir.
532      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
533        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
534    o eesupp/src:
535      - added SINGLE_DISK_IO option because reading of parameter files on
536        very large number of processors did not work with existing set-up
537    
538    checkpoint64o (2013/09/25)
539    o pkg/atm_phys & atm_compon_interf:
540      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
541    o tools/build_options:
542      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
543        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
544        remove CPP setting (was identical to genmake2 default).
545    o pkg/gmredi & model/src: Some updating and work done on the residual model.
546      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
547      - fixed up the calculation of the eddy stress and how it is added to the
548        external forcing via taueddy_external_forcing.F
549      - at the moment, it is very experimental and only works with the variable eddy
550        diffusivity calculated in gmredi_k3d.F
551    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
552        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
553    o testreport (& tools/do_tst_2+2):
554      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
555    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
556      - remove CPP='cpp -traditional -P' (this is genmake2 default)
557      - add switch (for big setups) to use 'medium' memory-model (but leave it
558        commented out for now). Note: needed with FC 19 to compile big setups.
559    o pkg/atm_compon_interf:
560      - regroup per field origin (model & pkgs) the coupling storage routines
561         (which accumalate in time each coupling field)
562      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
563        update accordingly + simplify aim_do_physics.F
564    
565    checkpoint64n (2013/08/26)
566    o pkg/bbl:
567      - update formulation to reduce dispersion of tracer properties in bbl
568      - replaced horizontal and vertical transport parameters with velocities
569      - changes results for verification/global_with_exf.yearly
570    o verification/halfpipe_streamice:
571      - change to matrix construction; update both Fwd & AD output.
572    o verification/tutorial_tracer_adjsens:
573      - OpenAD test: switch to vector-invariant momentum since fluxform with
574        rStar causes problems with OpenAD; update output.
575    o tools:
576      - genmake2: define a common prefix for all temp-file names ; move them
577        to local /tmp disk (but would be easy to move them back);
578      - xmakedepend: apply the same switch for temp-files.
579    o pkg/offline:
580      - changes for use with rStar (NLFS): assume that we continue to provide
581        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
582        output files) and apply r* scaling at each time-step (function of the time
583        varying Eta field); use normal pickup files (needed for restart with NLFS).
584    o adjoint with OpenAD:
585      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
586        package openad.  This package has to be compiled for all runs with OpenAD
587        instead of specifying code_oad_all as a modification directory.
588      - link the fortran templates from tools/OAD_support to the build directory
589        for preprocessing to avoid conflicts between different setups compiled
590        simultaneously and simplify cleanup.
591    o pkg/exf:
592      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
593        main model or other pkgs are exchanged in EXF_MAPFIELDS).
594    o model/src:
595      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
596        (similar to do_fields_blocking_exchanges.F).
597    o tools/genmake2:
598      - remove TAF output src code just before calling staf (when not doing a fresh
599        built, will stop if things go wrong with staf).
600      - fix target "adobj" (left from TAF version-2 transition)
601    o pkg/diagnostics:
602      - add a parameter to track the status of pkg/diagnostics activation;
603        this replace/extend the use of logical param "settingDiags" (to check
604        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
605        New S/R to print error message and stop when pkgStatus is not right.
606      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
607    
608    checkpoint64m (2013/08/13)
609    o model/inc:
610      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
611        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
612    o pkg/kpp & aim_v23:
613      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
614    o pkg/seaice:
615      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
616        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
617      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
618    o eesupp/src:
619      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
620        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
621    o switch to TAF version-2:
622      - add flow directives to "freeze" naming convention for ad-routines that
623        are used in I/O routines of adjoint state and associated common blocks
624        that are used in adcommon.h (backward compatible with version-1)
625      - update all ad-optfiles (in tools/adjoint_options + few local to some
626        verification exp) to switch to latest TAF version (currently 2.5.5);
627        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
628        out except for diva).
629      - the major change with TAF version-2 is that both the differentiated
630        routines and the forward routines (new) are returned as part of the TAF
631        output source code. Update genmake2 accordingly.
632      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
633        with version-2 when compared to TLM or FWD gradient); other experiments
634        output show minor changes (machine truncation level); update the few AD &
635        TLM output with 12 matching digits only (some prior to version-2 switch).
636    
637    checkpoint64l (2013/08/05)
638    o model/src:
639      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
640      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
641        when using TAF but only if using OpenAD.
642    o pkg/mom_common+fluxform+vecinv:
643      - always set horiz. viscosity arrays to background value before calling
644        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
645        only when using variable horiz. viscosity (useVariableVisc=T);
646      - simplify mom_vecinv.F (only 1 block for momViscosity).
647    o pkg/mom_common: variable horiz. viscosity in NH code
648      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
649        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
650      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
651        useBiharmonicVisc & useVariableVisc.
652      - fix old bug (already in 1rst implementation of variable horizontal viscosity
653        in calc_gw.F, version 1.27, 2006/06/20):
654        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
655        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
656      - change background horiz viscosity in vertical momentum (gW) to always be
657        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
658        any type of variable viscosity, e.g., viscAh/4Grid)
659      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
660        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
661        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
662        default viscAh,viscA4 is zero).
663    o model/src:
664      - extend length of drC & recip_drC from Nr to Nr+1.
665    o Divided Adjoint (DIVA) with MPI:
666      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
667      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
668        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
669    
670    checkpoint64k (2013/07/23)
671    o tools/OAD_support:
672      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
673        and remove it from genmake2.
674    o tools/build_options:
675      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
676        MPI_HEADER_FILES list (let genmake2 find the missing headers)
677    o verification/halfpipe_streamice:
678      - change to driving stress formulation; update both Fwd & AD output.
679    o tools/genmake2 and Divided Adjoint with MPI:
680      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
681      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
682      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
683        Makefile, which is set by genmake2, and check which mpi-headers are needed.
684        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
685      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
686    o testreport:
687      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
688        perform additional runs (number of additional runs is "add_DIVA_runs" taken
689        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
690    o verification/lab_sea (AD test):
691      - change to test Divided Adjoint Run in this set-up (both standard AD test
692        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
693    o pkg atm_ & ocn_compon_interf:
694      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
695        staggerTimeStep implementation) and disable (retired) corresponding
696        parameter.
697    o pkg/offline:
698      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
699      - add S/R OFFLINE_CHECK to print offline parameter summary
700        and stop if loading a file that is not used;
701      - enable to calculate GMRedi tensor, KPP mixing and convective index
702        when the corresponding file(s) is/are not specified (but pkg is used).
703      - comment out resetting of monitorFreq (to endTime) since it still useful
704        for monitoring CFL numbers and checking offline fields.
705    o OpenAD:
706      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
707        smaller standard output) and generate new (smaller) output (on baudelaire
708        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
709    o model/src:
710      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
711        (where external_forcing_adjust was called) and change list of arguments;
712      - merge external_forcing_adjust.F into external_forcing_surf.F
713      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
714        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
715        previously in file "balance_relax.F", now removed); remove corresponding
716        arrays in FFIELDS.h.
717      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
718        a hack for getting back surfaceForcingS (loaded from file) when using
719        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
720      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
721        (was getting only 11 digits for AD-grad, due to different truncation
722         error in AD code).
723    
724    checkpoint64j (2013/07/04)
725    o pkg/offline:
726      - to enable the use of other features with pkg offline (e.g., obcs),
727        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
728      - comment out "allowFreezing" (now active) in 2 offline testing exp.
729    o pkg/exf ALLOW_RUNOFTEMP
730      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
731      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
732      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
733    o pkg/atm_phys:
734      - allows to add some damping on uVel,vVel (strength only function of k).
735    o verification, ad-tests:
736      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
737        global_ocean_ebm and offline_exf_seaice.thsice.
738    o verification/halfpipe_streamice:
739      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
740        flux input boundary conditions to be ignored; a fix for this bug changed
741        verification results for forward test.
742      - add adjoint test.
743    o pkg/ptracers:
744      - allow to restart without SOM pickup (resetting SOM to zero).
745    o pkg/gmredi:
746      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
747      - It uses mixing length theory and suppression by steering level effects to
748        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
749        to JPO, for more details).
750      - It also uses the diffusivity to calculate an eddy induced streamfunction
751        based on a PV closure (rather than a buoyancy closure as in GM).
752      - New files added to pkg/gmredi:
753        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
754          induced overturning streamfunction (called from gmredi_calc_tensor)
755        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
756          for use in gmredi_k3d
757        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
758          the eddy diffusivity
759    
760    checkpoint64i (2013/06/18)
761    o pkg/cheapaml:
762      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
763        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
764        with pkg/cheapaml.
765    o utils/python: add subpackage for cubed sphere function, first example is
766        simple cs.pcol to plot 2D fields on a map
767    o pkg/streamice:
768      - This is a new package in MITgcm, which solves dynamic equations for ice
769         sheets and ice streams
770      - At the moment it is independent of atmosphere/ocean dynamics, or any
771        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
772        ed that this will change)
773      - There is a new verification exercise that tests it, halfpipe_streamice,
774        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
775        rectangular embayment
776      - halfpipe_streamice is forward-only for now, will have TAF test soon
777      - for questions, email dgoldber@mit.edu
778    o pkg/thsice:
779      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
780        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
781      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
782         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
783      - allow precip from pkg/cheapaml to make snow over seaice.
784    o pkg/cfc:
785      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
786      - remove atmos CFC 2-D arrays from common bloc (now local variables)
787      - change some hard-coded constant to run time parameter for reading and
788        and interpolating atmospheric CFC ; keep same default as previously.
789      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
790      - put arguments in standard order: myTime, myIter, myThid
791      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
792        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
793      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
794      - new routine to print summary of CFC params and check for consistency.
795    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
796      similar to thsice_advdiff.
797      Note that for the B-grid case the routine parameters uc/vc are overwritten.
798    o pkg/cfc:
799      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
800        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
801      - fix interpolation of atmphspheric CFC between Sorthern and Northern
802        hemisphere value.
803    o pkg/seaice:
804      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
805    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
806                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
807      - requires an additional time level that is stored in the pickup
808      - you can start with AB2 from a pickup without this time level with
809        pickupStrictlyMatch = .false.
810    
811    checkpoint64h (2013/05/26)
812    o pkg/cheapaml:
813      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
814        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
815      - consistent treatment of uWind,vWind location: assume everywhere in
816        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
817        (Note: was already the case for Tair,Qair advection);
818        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
819      - compute diabatic forcing only in the interior (excluding overlap regions)
820      - fill in array "Qsw" (for short-wave heating);
821      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
822        before any update (consistent with MITgcm state var diagnostics);
823      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
824        non periodic ; + adjusted for uWind,vWind (C-grid).
825    o pkg/seaice:
826      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
827        add explicitly pkg/exf in experiments that currently use pkg/seaice.
828      - allows to compile pkg/seaice without pkg/exf.
829    o tools/OAD_support:
830      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
831        of array "ourStepOf" in function rvNextAction (revolve.F90).
832    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
833      - change pkg name (to be used with other atmospheric physics pkg)
834        but by-pass CVS when making the new pkg so that we keep the CVS history.
835    o pkg/offline:
836      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
837        (previously called from pkg/dic_surfforcing_init.F)
838    o model/src:
839      - re-order sequence of calls within packages_init_variables.F, using
840        standard order, except for:
841         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
842         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
843    o new pkg: atm_phys
844      - add entry point and source code (previously in contrib
845          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
846        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
847      - re-order sequence of calls within packages_readparms.F,
848         packages_init_fixed.F and packages_write_pickup.F
849        (but skip packages_init_variables.F because of TAF issues).
850      - update contrib/*/atm_gray/ experiment.
851    o pkg/seaice (ITD code):
852      - simplify and fix the writing of pickup-files for ITD case
853    o pkg/seaice (ITD code):
854      - introduce floe size dependent lateral melt for ITD case;
855      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
856      - update seaice_itd experiment main output.
857    o pkg/thsice:
858      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
859        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
860        changed accordingly pkg/atm2d.
861    
862    checkpoint64g (2013/05/01)
863    o pkg/exf ALLOW_RUNOFTEMP
864      - if defined,  river and glacier runoff temperature can be read-in from
865        runoftempfile; runoftempfile needs to have same format as runofffile
866    o pkg/thsice (& pkg/bulk_force):
867      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
868        for energy content of Precip + RunOff & Evap (like with pkg/exf).
869      - change computation domain to always be the interior (without overlap).
870      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
871    o verification/tutorial_global_oce_biogeo:
872      - add preliminary OpenAD setup (still has problems)
873    o pkg/seaice:
874      - turn some parameters for choosing the convergence criterion of
875        the inexact Newton method (JFNK) into runtime parameters for convenience
876      - clean up seaice_calc_viscosities.F: remove/retire two options for
877        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
878        the results of lab_sea/input because a division has been replaced by
879        a multiplication with the reciprocal (sumNorm)
880      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
881        convergence of solver (changes results, of course), and to test some
882        new features
883    o model/src:
884      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
885      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
886      - move forcing adjustment (balancing surface forcing) in specific S/R
887        where might also be applied exchanges (if needed) to forcing arrays.
888    o pkg/shelfice:
889      - allow to specify the Ice-Shelf mass per unit area (instead of
890        shelficeLoadAnomaly) and do the conversion from one to the other
891      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
892        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
893        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
894        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
895      - update isomip experiment forward output (get machine truncation error
896        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
897    o verification/offline_exf_seaice:
898      revise data.seaice in input.thermo and input_ad and update results accordingly
899        HO = 0.2, SEAICE_areaLossFormula = 2,
900        SEAICE_growMeltByConv = .TRUE.,
901        SEAICE_doOpenWaterMelt = .TRUE.,
902      Improve consistency with input.thsice and fix the spurious 500m ice corners
903    o verification/global_ocean.cs32x15:
904      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
905        in icedyn (thsice+seaice-dyn) test and update output.
906    o verification/offline_exf_seaice:
907      - adjust list of tested variables (with testreport) and update
908        standard test output with better slection of monitored fields.
909    o pkg/cd_code:
910      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
911        experiment lab_sea.hb87
912    o tools/genmake2:
913      - change default makedepend from the system default to tools/xmakedepend:
914        When no makedepend is specified, select tools/xmakedepend it the test pass,
915        otherwise select the system default (if exist and pass the test) or
916        try to build cyrus-makedepend ; stop if none of the 3 works.
917    o pkg/exf & pkg/thsice:
918      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
919        for energy content of Precip + RunOff & Evap. Assumes:
920       1) Rain has same temp as Air.
921       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
922       3) Run-Off comes at the temp of surface water (with same Cp)
923       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
924        put directly into Latent Heat flux & should use water-vapor heat capacity.
925       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
926        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
927    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
928        (compile when SEAICE_ALLOW_JFNK is defined)
929    o pkg/thsice:
930      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
931        implementation): move THSICE_AVE call after the advection (called directly
932        from thsice_do_advect.F).
933    o verification/global_ocean.90x40x15 and OpenAD:
934      New experiment for OpenAD is identical to the one in input_ad except that
935        multiDimAdvection=.FALSE.,
936      There is still an issue with this.
937    o pkg/thsice:
938      - account for ice velocity (ocean relative velocity) in turbulent heat flux
939        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
940        and offline_exf_seaice (main test).
941    
942    checkpoint64f (2013/03/31)
943    o verification/OpenAD:
944      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
945    o verification/isomip, pkg/shelfice and OpenAD:
946      - add OpenAD setup to this exp and make shelfice package work with OpenAD
947    o verification/tutorial_global_oce_biogeo:
948      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
949    o verification/offline_exf_seaice:
950      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
951    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
952      - add OpenAD setup to this exp and make ptracers package work with OpenAD
953    o pkg/seaice/seaice_evp.F:
954       mask the asymmetric contribution of the ice-ocean stress (when
955       the turningAngle is non-zero) over open water to avoid stripes
956       in the EVP-solutions after many EVP-substeps. This does not change
957       the verification experiment (because turningAngle=0 in that experiment),
958       but will affect other EVP solutions with turningAngle.ne.0
959    o verification, AD & TLM output:
960      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
961        additions and multiplications which affect results at machine truncation
962        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
963        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
964        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
965        digits of matching.
966    o pkg/seaice:
967       modify lsr-algorithm so that it vectorizes AND converges by using a
968       "zebra" method: split vector loop into two with step size 2; this
969       solves a general convergence problem for the JFNK solver on a vector
970       computer. It has the potential to even improve convergence for
971       non-vector machines, but it does change the results so it is turned
972       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
973       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
974    
975    checkpoint64e (2013/03/05)
976    o pkg/ecco and several verification experiments:
977       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
978       from ecco package, and revert to unified routine in model/src/
979       Adjust verification experiments accordingly, especially gloal_oce_llc90
980       Should conclude long-standing work by Gael to reconsile the_main_loop with
981       ECCO and will enable OpenAD's revolve loop in ECCO setup.
982    o pkg/generic_advdiff:
983      - implement compressible flow method for multi-dim advection (similar to
984        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
985        TAF generates many recomputations) to use it; no yet coded with implicit
986        vertical advection.
987      - change experiment advect_cs (new output) and advect_xy (same output)
988        to test compressible flow multi-dim advection.
989    o pkg/generic_advdiff:
990      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
991        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
992    o pkg/seaice:
993      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
994        bug affects two verification experiments (lab_sea and lab_sea.hb87),
995        recover old (wrong) results by setting noSlipFac = 2. in
996        seaice_calc_strainrates.F;
997      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
998      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
999        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
1000      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
1001    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
1002      - new subroutines seaice_lsr_tridiagu/v
1003      - introduce loop bounds i/jmin/max to be able to use a restricted
1004        additive Schwarz method, but not used for now.
1005      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
1006      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
1007    o OpenAD support
1008       Reorganize S/R call for overall time-stepping loop to facilitate
1009       OpenAD revolve loop replacement
1010       (new S/R main_do_loop.F)
1011    o model/src:
1012      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
1013      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
1014        ADAMS_BASHFORTH2.
1015    o pkg/cheapaml:
1016      - add new parameter (default=F, same as before) to disable full domain
1017        (including land) periodicity in X & Y dir.
1018      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
1019        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
1020        into single S/R CHEAPAML_TIMESTEP.
1021    
1022    checkpoint64d (2013/02/17)
1023    o pkg/monitor (angular momentum):
1024      - do not add Eta contribution to the total AM if using rigid-lid;
1025      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
1026      - horizontal discretisation: compute Zonal wind contribution separately for
1027        each component (instead of from cell centered averaged) and use the 4
1028        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
1029      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
1030        FreeSurf) if using vectorInvariant momentum.
1031    o model/src (horizontal grid):
1032      - move initialisation of all horizontal grid arrays to null value
1033        from specific horizontal grid S/R to main S/R INI_GRID;
1034      - add 2 new arrays to project model C-grid velocity on to zonal direction
1035        (similar to AngleCosC & -AngleSinC but at U and V point location) and
1036        compute them in S/R CALC_GRID_ANGLES.
1037    o pkg/seaice: replace a hard coded parameter by a runtime parameter
1038        SEAICE_JFNK_tolIter
1039    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
1040        preconditioner for JFNK (run LSR into the overlaps as far as possible,
1041        i.e OLx/y-2, but overwrite the solution in the overlaps)
1042      - extend loop range in seaice_calc_viscosity
1043      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
1044      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
1045      - slightly modify loops in tridiagonal solver lsr-preconditioner
1046      - by default remove the extra exchange in seaice_preconditioner with a
1047        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
1048      - modify offline_exf_seaice so that old results without RAS are reproduced
1049        for output.dyn_jfnk.txt
1050      in seaice_fgmres.F (unrelated to RAS)
1051      - add a cpp-flag option for a re-ordered mapping (potentially more
1052        efficient), but because this changes the results, turn it off by
1053        default
1054      - replace the save statement by local common blocks
1055    o utils/matlab:
1056      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
1057      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
1058        instead of local script "load_cs.m".
1059    o pkg/seaice:
1060      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
1061        to the scalarProductMetric and the unrolling. By chance this does not
1062        change the verification experiment, because of the particular domain
1063        decomposition
1064    o pkg/diagnostics:
1065      - change default missing_value from UNSET_RL to -999.
1066    o pkg/layers: improve vectorization of layers_fluxcalc.F
1067      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
1068        time spent in this routine by more than a factor of 3 on an NEC-SX8
1069      - step 2: replace search algorithm by a bisection algorithm found in
1070        Press et al. Numerical Recipes in Fortran. This algorithm can be
1071        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
1072        For now, use this algorithm only for TARGET_NEC_SX defined.
1073      - moved the search algorithm into a separate subroutine, that is kept
1074        within the same file for automatic inlining.
1075      - modified catching potential errors
1076    o pkg/ecco:
1077      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
1078    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
1079      - modifications for ALLOW_GENTIM2D_CONTROL
1080      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
1081      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
1082      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
1083      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
1084    o model/src:
1085      - account for moist thermodynamics in (dry) potential temperature equation;
1086        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
1087        and cpl_aim+ocn.
1088      - also switch to standard compiler (gfortran, was using ifort previously)
1089        for fizhi-cs experiments reference output.
1090    o pkg/ctrl:
1091      - 1st step toward generic time-varying control variable (2D) via CPP option
1092        ALLOW_GENTIM2D_CONTROL
1093      - note new namelist ctrl_nml_genarr in data.ctrl
1094    o verification/global_ocean.cs32x15:
1095      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
1096        thsice calling sequence and update "output.icedyn.txt" output file.
1097    o pkg/ptracers:
1098      - from Ryan A.: code to allow to restart a tracer at regular time interval
1099        specifying a reset frequency and a reset-phase (for each tracers).
1100    o pkg/thsice:
1101      - implement new sequence of calls for thsice+seaice:
1102          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
1103          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
1104      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
1105        in CPP_OPTIONS.h) to recover old sequence;
1106      - update diagnostics for Intermediate State thsice diagnostics: now filled
1107        just before advection (instead of just after advection in old sequence);
1108      - update output of experiment offline_exf_seaice (standard test);
1109      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
1110        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
1111    o pkg/aim_v23:
1112      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
1113      - use standard pkg/mdsio routines to read & write CO2 pickup file;
1114      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
1115      - Implement new sequence of calls for seaice advection (with thsice and
1116        seaice diffusion): do ice advection after ice-Thermodynamic (previously
1117        was done before); change aim_do_physics.F (split the bi,bj loops block);
1118      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1119    o pkg/thsice:
1120      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1121        where just seaice diffusion is used without seaice-dynamics.
1122    
1123    checkpoint64c (2013/01/18)
1124    o pkg/seaice:
1125      - add a parameter JFNKres_tFac that can replace JFNKres_t
1126        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1127      - add a line search option to the JFNK solver
1128      - move update of u/vIce and computation of initial residual into a separate
1129        routine (same file); makes the code a little easier to read (?)
1130      - the line search requires computation of the residual and for some reason
1131        I cannot do the update of u/vIce at the beginning of the Newton loop
1132        without changing the results, so we move computation of the new residual
1133        also to the end of the Newton loop, even without the line search
1134    o pkg/mdsio:
1135      - write missing value (corresponding to undefined array value) to meta files;
1136        skip this if missing value is one (UNSET_RL would be a better value for the
1137        case of undefined missing value but it's current the default missing-value);
1138        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1139    o pkg/exf & thsice:
1140      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1141        diagnostics) even when SHORTWAVE_HEATING is #undef;
1142    o verification/cfc_example:
1143      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1144        illustrate how to use it).
1145    o verification/offline_exf_seaice:
1146      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1147        files to only one time-record.
1148      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1149        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1150        snapshot output; same mcPheePiston value as in thsice with
1151        surf-current=0.2m/s.
1152      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1153        initial conditions).
1154    o verification/cfc_example:
1155      - update file "data" with more standard choice (default rotationPeriod,
1156        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1157        set deltaTFreeSurf to deltaTtracer) and update the output.
1158    o pkg/layers:
1159      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1160      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1161    o verification/offline_exf_seaice:
1162      - set all {field}period to zero for constant-in-time forcing (not tested
1163        anywhere else).
1164    o verification/offline_exf_seaice:
1165      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1166      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1167    o model/src:
1168      - implement Finite-Volume method for (hydrostatic) presure gradient
1169        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1170    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1171      - In order to be compatible with the default EVP code, this requires changing
1172        the EVP code around a little; and because any small change immediately
1173        breaks the lab_sea.hb87 verification experiment, the reference output is
1174        updated two times (each time the remaining aggrement was only 2 digits):
1175        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1176        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1177        The adjoint test lab_sea.evp also needed to be updated.
1178      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1179        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1180        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1181        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1182        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1183        kept obscure, because I need to test it a little more.
1184    o pkg/cheapaml:
1185      - fix few incorrect type (_RL/_RS) in subroutine calls.
1186    o pkg/seaice:
1187      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1188        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1189    o model/src:
1190      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1191        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1192        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1193    o pkg/cheapaml:
1194      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1195        update output of experiment cheapAML_box.
1196      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1197        and set them only in one place (cheapaml_readparms.F).
1198      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1199      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1200        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1201    o model/src/the_main_loop.F:
1202      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1203    o pkg/seaice:
1204      - remove legacy branch code.
1205      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1206    o verification/*/code*/SEAICE_OPTIONS.h:
1207      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1208        SEAICE_CAP_HEFF).
1209    o pkg/cheapaml:
1210      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1211        to load new forcing fields.
1212      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1213      - remove switch to "-r8" compiler option (no longer needed) in verification
1214        cheapAML_box, keep same output (small trucation error differences).
1215    o verification/offline_exf_seaice:
1216      - add thermodynamics only test.
1217    o verification/cheapAML_box:
1218      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1219        keep same output (same 14 digits for cg2d).
1220      - switch on "-r8" compiler option (some numerical values are missing
1221        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1222    
1223    checkpoint64b (2012/12/24)
1224    o pkg/cheapaml:
1225      - remove un-used variables (Qnet,EmPmR) from pickup files.
1226      - store tendency of advected variables into cheapaml pickup file
1227        and fix the AB-2 restart.
1228    o verification/offline_exf_seaice and lab_sea adjoint:
1229      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1230      - switch to 4 time steps in offline, consistent with lab_sea.
1231      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1232      - update results after change of experiment seaice.
1233    o pkg/seaice:
1234      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1235        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1236        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1237        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1238    o model/src:
1239      - add run-time parameter to select CG2D solver minimum-residual solution
1240        (in case of a poor convergence).
1241    o pkg/seaice/seaice_lsr.F
1242      - move calculation of matrix coefficients into new
1243        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1244        file; the main purpose of this change is to be able to reuse the code
1245        in S/R SEAICE_PRECONDITIONER
1246      - modify the computation of the residual so that the mass of sea-ice
1247        is not used twice; this simplifies the calculations, but since
1248        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1249        not tested in testreport---this does not affect the testreport results.
1250    o verification/seaice_obcs:
1251      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1252        verification/lab_sea/input.salt_plume; changes results/output.txt*
1253    o model/src:
1254      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1255    o pkg/seaice:
1256      - improve description of parameters in seaice_fgmres.F and start
1257        cleaning up the code
1258      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1259        second argument
1260      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1261        results of offline_exf_seaice.dyn_jfnk
1262      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1263    o pkg/aim_v23:
1264      - fix an other bug in dissipation heating (grid-cell area was missing).
1265    o model/src + pkg/seaice:
1266      - add global (multi-tile) linear solver for pair of tri-diagonal system
1267        along X and Y lines, respectively for U and V component.
1268        Note: 1) MPI and cube-exchange not yet coded.
1269            2) probably not accurate for poorly conditioned / large size problem.
1270      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1271        default: not compiled and not used.
1272    o pkg/seaice:
1273      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1274        introduce bi/bj loops and use global_sum_tile_rl instead of
1275        mpi_allreduce in seaice_fgmres.F
1276      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1277      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1278      - add a verification experiment for JFNK in offline_exf_seaice
1279    o verification:
1280      - change (for now, only fwd test) offline_exf_seaice experiment:
1281        use a re-entrant channel with idealized coastline (trapezoidal shape)
1282        at southern boundary to explore seaice dynamics and thermodynamics
1283        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1284        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1285      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1286    o pkg/exf:
1287      - disable "sstExtrapol" when Nr=1
1288    o verification:
1289      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1290        to test pkg/cheapaml.
1291    o pkg/aim_v23 & pkg/shap_filt:
1292      - fix dissipation heating (erroneous gravity multiplication factor).
1293    o pkg/seaice:
1294      - remove unused field pressPre from jfnk solver
1295      - rename two subroutines in seaice_preconditioner.F
1296    o eesupp/src:
1297       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1298    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1299       - remove wrong parts of the rhs and the lhs (were in there
1300         because I did not understand the concept of this preconditioner)
1301       - add an exchange between u- and v-sweep. This increases communication
1302         by a factor of two but improves the convergence of jfnk. Ideally,
1303         one would like the u- and v-sweep to be independent. So far within
1304         undocumented ifdefs
1305       - reorganize the extra computations for printing the residuals
1306    o tools/genmake2:
1307      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1308        since it's not necessary (and was preventing to use MNC in some cases).
1309    
1310    checkpoint64a (2012/11/16)
1311    o pkg/autodiff:
1312      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1313        autodiff_readparms.F no longer depends on calling order (within
1314        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1315        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1316        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1317    o pkg/obcs:
1318      - adding tidal velocity forcing capability to obcs
1319        for usage example, see verification/seaice_obcs/input.tides
1320    o pkg/seaice:
1321      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1322        SEAICE_LSRrelaxU/V
1323      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1324    o pkg/aim_v23:
1325      - implement heating from friction (bottom friction and stratospheric drag).
1326    o pkg/shap_filt:
1327      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1328        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1329    o model/src:
1330      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1331        time-constant addMass field from file (addMassFile);
1332      - support for heating due to friction (and Kinetic Energy dissipation):
1333        add option, run-time switch and 3-D field array + support code ; each pkg
1334        or S/R can add heating contribution (if there is a sink of KE); the sum is
1335        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1336    o pkg/seaice:
1337      - complete merge of ITD code into seaice_growth.F
1338        from MITgcm_contrib/torge/itd/code/
1339        no verification so far, but Torge Martin tested
1340        "1-D test case and Beaufort set up;
1341        deliver okay results after 1 model year."
1342      - complete merge of SEAICE_SIZE.h into all relevant routines
1343      - move computation of eta at Z-points into calc_viscosities
1344        + introduce global field etaZ
1345        + add different methods for computing etaZ, for now the old
1346          method (simple averages of eta to Z-points) is hardwired
1347        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1348          seaice_preconditioner
1349      - simplify computations for SEAICE_ZETA_SMOOTHREG
1350      - seaice_preconditioner:
1351        + replace one remaining press by pressLoc (mistake)
1352        + adjust printing of residuals
1353      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1354        + add (SEAICE.h) and rename some counters (initiliased in
1355          seaice_init_fixed.F)
1356        + add _BEGIN/END_MASTER (myThid)  around print statements
1357        + print total number of iterations and failures over SEAICE_monFreq
1358          interval to STDOUT
1359      - move control over output-messages by fgmres to seaice_jfnk to save
1360        some operations
1361      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1362        in order to make restarts with sol .ne. zero (fgmres with restarts)
1363        (seaice_jfnk.F, seaice_fgmres.F)
1364      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1365        a serious convergence problem when open boundaries are involved
1366    o pkg/ggl90: fix computation of control volumes for the case of
1367      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1368      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1369    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1370    o pkg/autodiff
1371      - Add inAdMode switch for SEAICEuseDYNAMICS:
1372        SEAICEuseDYNAMICSinAdMode
1373        (extend logic in ADAUTODIFF_INADMODE_SET)
1374    o pkg/seaice
1375      - Step 1 of merging ice-thickness distribution (ITD) code from
1376        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1377        The code implements concept laid out in Thorndike et al. (1975);
1378        code is enabled via CPP flag SEAICE_ITD
1379        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1380        code is not complete yet!!
1381      - SEAICE_SIZE.h now included in almost all seaice routines
1382    o verification (using seaice):
1383      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1384        global_ocean.cs32x15.seaice ; update results.
1385      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1386      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1387        offline_exf_seaice (previously compiling B-grid).
1388    o pkg/exf:
1389      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1390        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1391        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1392    o pkg/layers (adjust changes from Sept 19):
1393      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1394        this allows to remove "layers_maxNum" dimension from all layers arrays.
1395    o pkg/layers (adjust changes from Sept 19):
1396      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1397      - snap-shot extended to all type of layers (not just the 1rst type);
1398      - remove layers variables when corresponding CPP option is undef.
1399    o pkg/layers:
1400      - rename pkg/layers variable and add new output (layer exist & un-weighted
1401        velocity in layer)
1402    o pkg/seaice:
1403      - simplify (?) ocean-drag coefficent computations by using
1404        the same routine in all three solvers (saves some code lines)
1405      - remove global fields DRAGA and DRAGS from C-grid code and
1406        declare them locally in lsr.F (the only place where they are
1407        still used)
1408      - update AD output of lab_sea.evp (very sensitive anyway).
1409    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1410      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1411      and SEAICEuseJFNK=.true. A few things to note:
1412      - involves a FGMRES, that is parallel but very inefficient,
1413        because of many scalar products (global sums) in the Gram-Schmidt
1414        orthogonalization method. Needs to be replaced. Original code
1415        from J.-F. Lemieux
1416      - preconditioner for FGMRES is a stripped down version of LSOR
1417      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1418        preconditioner. For the preconditioner, the default is set to 10.
1419      - Jacobian times vector is computed with finite differences
1420      - marginally related to JFNK-solver: add a smooth regularization for
1421        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1422        2009) for any implicit solver (not implemented for EVP because EVP
1423        does not need this regularization in the first place). Define
1424        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1425    o eesupp/src:
1426      - check in genmake2 that intrinsic S/R flush is available.
1427      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1428      - flush standard & error msg unit before MPI termination
1429      - if debugMode, flush IO unit after printing msg
1430    o pkg/ctrl:
1431      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1432        to ctrl_set_unpack_xyz.
1433    
1434    checkpoint64 (2012/10/09)
1435    o pkg/shelfice
1436      - in mom_fluxform.F, mom_vecinv.F:
1437        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1438        Bug fix KappaRU -> KappaRV
1439        does not change verification/isomip but may change other setups
1440        (presumably constant KappaRU=KappaRV)
1441      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1442    o pkg/obcs:
1443      - fixed some indexing bugs in obcs_seaice_sponge.F
1444      - added obcs relaxation subroutines for HSALT and HSNOW
1445      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1446  o pkg/seaice:  o pkg/seaice:
1447    - add "multicategory" parameterization for snow in analogy to ice,    - add "multicategory" parameterization for snow in analogy to ice,
1448      default is off for now.      default is off for now.
