4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - collect momentum forcing tendency into local 2-D array (passed as argument
9        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
10        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
11        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
12      - collect T & S forcing tendency into local 2-D array (passed as argument to
13        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
14        affects results at machine truncation level (e.g., ocean: if using
15        SHORTWAVE_HEATING and atmos:, if using FrictionHeating or (atm_Rq<>0)
16        moist correction due to vertical advection).
17      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
18        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
19        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
20        obcs_ctrl (ad & fwd grd @ 12 & 7).
21    o pkg/ptracers & diagnostics:
22      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
23        title (to avoid some unexpected truncation); sort out ptracers diags units.
24      - collect ptracer forcing tendency into local 2-D array (passed as argument
25        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
26    
27    checkpoint65 (2014/07/18)
28    o pkg/fizhi:
29      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
30        affects results at machine truncation level. Update output of experiments
31        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
32    o pkg/seaice: more clean up
33      - rename TAF common block tapes to be more consistent and remove
34        unnecessary duplicates
35      - add store directives to remove more recomputations, but use smaller
36        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
37        The idea behind this flag is to reduce the memory footprint when the
38        adjoint of the LSR is not required. As of now, defining the flag
39        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
40        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
41        For experiment offline_exf_seaice, this means on a linux box with gfortran
42        nearly a factor of 10 (but keep in mind there is mostly seaice code in
43        this experiment):
44        > size mitgcmuv_ad
45        text    data        bss     dec        hex  
46        5100659 1216  220458952  225560827  d71c8fb
47        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
48        but only a moderate increase of 36% for global_ocean.cs32x15:
49        text    data        bss     dec        hex
50        6695027 1648 1014578664 1021275339 3cdf6ccb
51        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
52      - note: there are still recomputations in global_ocean.cs32x15 and
53        offline_exf_seaice and the gradient agreement changes (gets a
54        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
55      - in general, the AD gradients still are wrong
56    o OpenAD
57      - clean up code_oad/ directories somewhat by moving files
58        dontCompile, dontTransform, keepOriginal to OAD_support/
59    o model/src:
60      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
61        (not currently tested): add dissipation terms before NLFS rescaling of
62        tendencies (previously done after).
63    o pkg/diagnostics:
64      - write stats-diags in ascii file with more digits (same as in monitor).
65    o pkg/down_slope:
66      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
67        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
68    o model/src:
69      - new file "apply_forcing.F" containing all the code previously in
70        external_forcing.F, but with new argument list: pass, as new argument,
71        the current level tendency array to update (instead of a direct update
72        of the common bloc array). Change the corresponding calls.
73      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
74        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
75    o pkg/seaice/seaice_lsr, a little bit of clean up
76      - rearrange some code blocks, so that now all calculations for
77        setting up the right-hand-sides done within one single block
78        (I find that easier to read and understand)
79      - rearrange freedrift-code to reduce the number of ifdefs
80      - adjust some indentations and comments
81    
82    checkpoint64z (2014/07/10)
83    o model/src and several pkgs:
84      - change argument list of all S/R called from external_forcing.F and
85        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
86        to pass, as argument, the current level tendency array to update
87        (instead of a direct update of the common bloc array).
88      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
89      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
90    o pkg/seaice/seaice_lsr.F
91      - always initialize local arrays in seaice_lsr_tridiagu/v
92      - add more local tapes to seaice_lsr_tridiagu/v
93      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
94        keep it in bi/bj loop; this seems to be essential
95      - gradients are still wrong but only by 4-7 orders of magnitude
96        instead of 15 orders of magnitude, lab_sea improves a little
97    o pkg/seaice
98      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
99        generates unnecessary code in seaice_lsr_ad
100      - add more store directives in seaice_lsr to avoid unnecessary code
101        in seaice_lsr_ad
102      - exclude some residual computations in seaice_lsr when
103        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
104        in seaice_lsr_ad
105      - add more storing, a new tape (model/src/the_main_loop.F) and
106        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
107        and klockey should be checked by a specialist)
108      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
109        and update lab_sea after previous changes in pkg/seaice below
110    o pkg/autodiff:
111      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
112        viscFacInAd : run time parameters allowing for adjoint switches
113        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
114    o pkg/ecco:
115      - introduce cost_gencost_boxmean.F that computes a box mean
116        temperature (for use in adjoint sensitivity studies).
117    o model/src/set_defaults.F : initialize viscFacAdj to 1.
118    o pkg/mom_common/mom_calc_visc.F:
119      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
120    o pkg/seaice/seaice_summary.F:
121      - statement for SEAICEadjMODE now in autodiff_readparms.F
122    o pkg/seaice:
123      - remove some store directives and add new ones in an effort to get
124        finally rid off the recomputation warnings. This is successful
125        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
126        defined (i.e. no extensive recomputation warnings left), but there
127        are still too many recomputations on the solver iteration level
128      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
129      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
130        SEAICE_SIZE.h
131      - add a store directive in S/R seaice_calc_viscosities
132    o pkg/seaice (ITD code):
133      - fix definition of Hlimit for multi-threaded case
134      - use double precision arithmetic to compute Hlimit: this affects results;
135        update output of experiment seaice_itd.
136    o replace content of verification/seaice_itd
137      - instead of a 1D column use the configuration of offline_exf_seaice
138        to test the ice thickness distribution code with ridging
139      - this is a first shot at this experiment
140      - change of some defaults of ridging parameters SEAICEhStar (from
141        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
142        and lot of new comments.
143    
144    checkpoint64y (2014/06/20)
145    o pkg/seaice/seaice_reg_ridge.F:
146      - modify the regularization of very small volumes of ice; only check
147        total volume HEFF, and do not apply correction to individual ice
148        classes because that leads to funny patterns in the heat and fw-fluxes
149        into the ocean. Adjust seaice_itd/results/output.txt
150      - replace nITD by SEAICE_multDim in loop-ranges
151    o pkg/exf:
152      - add code to process the case field period = -12. with UV interpolation.
153      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
154        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
155    o verification/global_with_exf:
156      - switch all fields period to -12. (was previously untested) in input/data.exf
157        (but keep secondary test ".yearly" unchanged); update the reference output.
158    o pkg/cal:
159      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
160    o pkg/exf:
161      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
162        to replace logical switch "exf_verbose"
163      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
164    o pkg/sbo:
165      - update from Katherine Quinn: evaluate mass directly from density and SSH
166        (budget using Finite Volume method) instead of from bottom pressure.
167      - allow testreport to collect few selected SBO output ; tested in exp.
168        global_ocean.90x40x15 (after updating the results, to include SBO output).
169      - fix some multi-threading issues (in output part).
170    o model/src & most packages:
171      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
172      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
173        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
174        "data.{pkg}" exist ; and leave the S/R (return) just after.
175      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
176        + call LAND_READPARMS from packages_readparms.F
177    o pkg/seaice:
178      - remove code that resets useThSice in S/R seaice_readparms and
179        replace it by a warning in S/R seaice_check
180      - remove parameter MULTDIM, replace with nITD and runtime
181        parameter SEAICE_multDim (still hard-wired to nITD if
182        SEAICE_ITD is defined)
183    
184    checkpoint64x (2014/05/24)
185    o verification/lab_sea:
186      - update adjoint and TLM output following changes to pkg/salt_plume
187      - un-do the update after putting back local recip_Cp in few places.
188    o pkg/salt_plume: modifications by An Nguyen:
189      - add capability to do brine rejection (salt-plume) as function of
190        volume+tracers (instead of only salinity tracer).
191      - conserve volume by exchanging volume from each kLev to above to
192        accommodate in-coming brine volume
193      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
194      - switch KPP surf buoyancy due to brine forcing to 3-d
195        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
196      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
197      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
198        in East/West Arctic.
199    o pkg/sbo:
200      - incorporate modifications from Katherine Quinn to enable the use of sbo
201        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
202        output for future testreport verification (unfinished).
203    o pkg/atm_phys:
204      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
205        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
206        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
207    o pkg/seaice
208      seaice_calc_ice_strength.F: modify expression to avoid divisions
209        (affects truncation)
210      seaice_do_ridging.F: clean up the insectarium
211      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
212      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
213      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
214      - add some debugging information and error messages (warnings)
215    o model/src: modifications relatd to atmosphere p*:
216      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
217      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
218        of vertical profile tRef in geopotential background and anomaly.
219      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
220        and pkg/atm_phys.
221      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
222        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
223    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
224    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
225        not used right now, but can be used in BGC packages to fix conservation.
226    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
227        other packages too.
228    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
229        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
230    o model/src:
231      - since we have several heat capacity (even in model/src), define "recip_Cp"
232        as local variable (no longer in common block) to avoid any confusion.
233      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
234    o pkg/exf:
235      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
236        air density as function of air Temp, Humidity and atm pressure.
237    
238    checkpoint64w (2014/05/02)
239    o verification:
240      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
241        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
242        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
243        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
244        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
245    o model/src: for atmosphere in p* coords:
246      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
247      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
248        but not yet activated.
249    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
250      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
251      - this changes the results (but not for any verification experiment, because
252        none tests this), but avoids having an extra field in the restart files
253    o pkg/seaice: remove global variable TICE (not needed)
254      - replace by TICES or local variable where necessary (cost_seaice_test,
255        seaice_diagnostics_state)
256      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
257      - use specific read/write routines for reading and writing individual leves
258        of a multilevel field
259    o pkg/ctrl & model/inc:
260      - move additional anomaly fields of control vars (related to options:
261         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
262        from DYNVARS.h into new header file: CTRL_FIELDS.h
263    o pkg/seaice: some small modifications to the ridging code
264      - make fw2ObyRidge a global variable and add the freshwater flux to
265        seaice_growth
266      - pass actual thickness from seaice_prepare_ridging, so that it is
267        computed only in one place and compute it in the same way as in
268        seaice_growth
269      - initialise more fields in seaice_do_ridging that where cause floating
270        point exceptions over land
271    o pkg/seaice: preparations for ridging code and first real ridging code
272      - move most of "PART 1" of S/R seaice_growth into a new and separate
273        S/R seaice_reg_ridge that will both regularize the state variable after
274        advection call the actual ridging routine;
275      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
276        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
277      - remove ridging code from seaice_advdiff
278      - clean up remaining part 1 of seaice_growth in an attempt to make it
279        more readable (this is probably subjective)
280      - call seaice_itd_redist once in the initialisation phase to have the initial
281        conditions in the correct category
282      - finally: add new ridging routine for ITD code
283    
284    checkpoint64v (2014/04/11)
285    o pkg/ecco:
286      - add runtime parameters mdt[start,end]date[1,2]
287      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
288    o pkg/seaice:
289      - make deltaC a global variable, so that it can be used in ridging code
290      - first step towards ridging: introduce new routines that compute
291        ice strength based on ridging parameters
292      - add diagnostic for HSNOWITD
293      - add opnWtrFrac as a global variable (required for ridging scheme)
294    o pkg/salt_plume + pkg/seaice/seaice_growth.F
295      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
296        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
297    o verification/hs94.1x64x5:
298      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
299      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
300    o autodiff:
301      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
302        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
303        For now, only in pkgs used in verification/hs94.1x64x5.
304      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
305        which are specific to TAF/TAMC).
306      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
307        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
308        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
309      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
310        building mitgcmuv_ad (make adAll).
311    o pkg/ecco:
312      - cost_gencost_seaicev4.F:
313         reformulate proxy cost as function of sst and local param SEAICE_freeze
314         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
315      - add stop statement if old names siv4-[sst,vol] are used
316      - add snapshots + cost reports for atmospheric longwave
317      - remove factor 0.1 in front of wtau[u,v]
318      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
319         ALLOW_TMI_SST_COST_CONTRIBUTION
320    o pkg/atm_phys:
321      - add some diagnostics for Short-wave and for convection S/R.
322    o pkg/seaice/seaice_growth:
323      - fix a bug in the lateral melt parameterization for SEAICE_ITD
324        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
325      - rearrange loop order for better vector code in the same code block
326      - rewrite the floeDiameter formula to have fewer divisions
327      -  (miraculously) none of this changes the results of seaice_itd
328    o pkg/smooth:
329      - move param smooth2Ddiffnbt to pkg/ecco
330    o pkg/salt_plume:
331      - salt_plume_frac.F:
332         clean up local param names
333         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
334    o pkg/rw:
335      - add RS version of S/R READ_MFLDS_LEV.
336    o pkg/streamice:
337      - fix the restart test by writing/reading pickup_streamice files.
338    o pkg/seaice:
339      - refine checks for jfnk-related parameters
340      - comment out if statement with SEAICEuseIMEX parameter as long as there
341        is no IMEX code to avoid confusion and surprises
342    
343    checkpoint64u (2014/03/07)
344    o verification/MLAdjust:
345      - rename secondary test suffix:
346         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
347         0.leithD -> AhFlxF  + switch to flux-form
348         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
349         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
350    o pkg/mom_vecinv:
351      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
352        to be before mom_calc_visc.F)
353      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
354      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
355        this is simpler for the adjoint and for diagnostics.
356    o model/src + pkg/momentum:
357      - add input files for  2-D additional Western and Southern cell-edge wall
358         (e.g., to add "thin-wall" where it is =1).
359      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
360        using 2nd hFacZ that is computed from initial (fix domain) hFac
361      - known limitations of thin wall implementation: not yet coded for sigma
362        coords; not working with CD-scheme neither.
363    o pkg/seaice:
364      - rename recently introduced parameters from (wrong name) AB to
365        BDF (backward difference time discretisation)
366      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
367    o tools/adjoint_options:
368      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
369    
370    checkpoint64t (2014/02/01)
371    o pkg/ecco
372      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
373        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
374      - replace hard-coded record number and period which only work for monthly
375        with read-in runtime param that works for other periods (month,day,year)
376    o pkg/thsice
377      - corrected store directive fixes thsice adjoint gradient checks
378    o genmake2 & testreport:
379      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
380        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
381        Update testreport accordingly. No need to set "export OPENAD=true"
382        in adjoint_options/adjoint_oad anymore (will be removed later).
383    o pkg/shelfice:
384      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
385        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
386        so that surface forcing applies to k=kSurf if using pkg/shelfice.
387    o pkg/ctrl, pkg/grdchk, pkg/ecco:
388      - Changes to make GENARR more modular (i.e. invisible if not used)
389    o model/src/temp_integrate.F and salt_integrate.F
390      - re-include store directives that were removed on Dec 27th.
391    o model/src/external_forcing_surf.F
392      - add storage directives for EmPmR and PmEpR to avoid recomputation of
393        seaice_model in the adjoint that is problematic when seaice_model is
394        turned off in the adjoint. The resolved issue dated back to July when
395        EXTERNAL_FORCING_SURF call was moved.
396        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
397    o pkg/exf/exf_check.F
398      - fix a small bug again (originally found by Wentao Liu, now found again)
399      - streamline error output
400    o pkg/streamice and aim_v23:
401      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
402        Apple's /usr/bin/cpp knows what to do:
403        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
404        Target: x86_64-apple-darwin13.0.0
405    
406    checkpoint64s (2014/01/05)
407    o tools/adjoint_options:
408      - switch to fastopt.net TAF server (instead of default fastopt.de) for
409        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
410    o model/src:
411      - remove some unnecessary TAF storage directives in forward_step.F and
412        in dynamics.F (note: not always removed by TAF, e.g., double storage
413        of kappaRU,kappaRV in former version of dynamics.F).
414    o model/src & pkg/ptracers:
415      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
416        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
417        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
418      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
419      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
420      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
421    o useSingleCpuInput separates single-CPU input from single-CPU output;
422        for now only implemented for in exf_interp_read.F
423    o verification/advect_xy:
424      - fix missing EXCH call in local version of ini_salt.F and update output.
425    o momentum diagnostics:
426      - fix which deltaT is used in Total-Tendency diagnostics.
427      - fix typo in diagnostics for momentum tendency from AB.
428    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
429        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
430    
431    checkpoint64r (2013/12/08)
432    o verification/*/results:
433      - Update reference output of experiments that were passing with just 13 digits
434         (make it easier to detect future changes in results)
435    o model/src & pkg/ptracers:
436      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
437        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
438        to inside ptracers_integrate.F ; remove ptracers_advection.F
439    o coupling interface pkgs:
440        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
441      - change the config check to test the agreement of Ocean Depth
442        with ATM land/sea mask (instead of ATM orography);
443      - send to coupler the number of coupler time-steps to do for this run:
444        this allows to check for consistency and don't need anymore to be
445        specified in parameter file "data";
446      in coupler:
447      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
448      - improve report to log-file of config setting (pass log-file unit to few S/R)
449    o pkg/compon_communic:
450      - add coupling send/receive for non-tiled integer vector;
451      - add S/R to check and stop if any proc has an error (similar to
452        eesupp/src/stop_if_error.F but single thread and across Comm_World).
453    o pkg/exch2:
454      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
455        through list of all tiles my proc owns.
456    o model/src:
457      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
458        from rTrans) to simplify dependencies (no need to store rTrans anymore in
459        calling S/R); this affects AD results at machine truncation level:
460        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
461        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
462    o tools/build_options:
463      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
464    o coupling interface pkgs:
465        [compon_communic, atm_compon_interf & ocn_compon_interf]
466      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
467        to each S/R that needs it; remove un-used variables.
468      - change component tile registration (cpl_register.F in both compon_interf
469        and mitcomponent_tile_register.F) to pass the full list of tiles
470        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
471      - with pkg/exch2: adopt the same convention used for I/O to define mapping
472        towards coupler global array (unless W2_useE2ioLayOut=F):
473         a) can now use different tiling between atm & ocn comp.
474         b) no needs to modify the run-Off map when changing tiling (was needed
475            even if using the same tiling between atm & ocn).
476         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
477            full land tiles); not yet tested.
478      - check for valid mapping from comp. tile to coupler global array
479      - improve report of tile registration results to log file.
480    o pkg/exch2:
481      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
482        tile-registration (CPL_REGISTER);
483      - activate (un-comment) definition and setting of "W2_tileIndex" list to
484        store the local bi,bj indices of each tile;
485      - also print bi,bj in local report to log file;
486      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
487        Jun 2009 modif of pkg/exch2).
488    o testing on baudelaire:
489      - run 2 tests at a time: no significant slow down (since enough cpu) and
490        get the full set of test done earlier
491      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
492    o model/src/thermodynamics.F and routines called from it:
493      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
494        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
495        velocity (outp) by adding bolus velocity.
496      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
497        mass transport from velocity + lateral grid cell area
498      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
499      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
500     in thermodynamics.F
501      - remove k from thermodynamics.F and move it to temp_integrate.F
502        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
503        loop).
504      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
505        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
506        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
507        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
508      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
509        global_ocean.90x40x15, tutorial_global_oce_biogeo and
510        tutorial_tracer_adjsens (+ TLM output).
511    o tools/OAD_support and (verification/*/) code_oad:
512      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
513        module conversion ; remove unneeded CPP_EEOPTIONS.h.
514      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
515        version (closer to model/inc/CPP_OPTIONS.h).
516    o model/src:
517      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
518        retired list of parameters (routine FREEZE has been replace by surface
519        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
520    o pkg/gmredi:
521      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
522        velocity (same scheme but affects machine truncation) for GM_AdvForm.
523      - update output of FWD experiments: front_relax.bvp,
524        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
525    
526    checkpoint64q (2013/11/17)
527    o verification:
528      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
529        tutorial_global_oce_biogeo and global_ocean.90x40x15.
530      - generate new output (growth & melt) for seaice_itd experiment after
531        updating the input pickup_seaice files (previously wrong).
532    o pkg/cost:
533      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
534        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
535        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
536          cannot be applied to var in common block).
537        o allows to get results independent of tile-per-proc setting (if using
538          slower GLOBAL_SUM_SEND_RECV option).
539      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
540        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
541        forward gradients: update output).
542      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
543        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
544    o pkg/mom_common:
545      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
546        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
547        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
548        ensure that all field value that are used are set.
549    o tutorial_deep_convection (smag3d):
550      - add missing scaling in mom_calc_smag_3d.F;
551      - set smag3D_coeff in input.smag3d such that results do not change.
552    o pkg/dic:
553      - change dic_cost.F to compute cost on each tile first and then apply
554        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
555        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
556      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
557    o eesupp/src & pkg/mdsio:
558      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
559        (from pkg/mdsio) since they are no longer used for tape IO.
560      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
561        (+ keep a copy in pkg/atm_ocn_coupler).
562    o verification/isomip:
563      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
564    o tools/build_options:
565      - optfile linux_amd64_ifort11, fast (no ieee) case:
566        to get a working restart for all experiments, add "-fp-model source"
567        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
568    
569    checkpoint64p (2013/10/20)
570    o pkg/autodiff:
571      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
572        criteria, return to simple (default) tape IO format.
573    o pkg/mdsio (+ eesupp/src):
574      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
575        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
576      - fix globalFile and singleCpuIO options using simpler global mapping.
577      - new pairs of scatter/gather vector S/R (one for each type, generated from
578        template) corresponding to simpler global mapping.
579      - adread_write.F: switch to new S/R (but leave old calls commented) and write
580        to globalFile when parameter globalFiles is set to True.
581      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
582    o pkg/autodiff:
583      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
584        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
585        missing, just add a STOP if array type do not match.
586    o pkg/exf:
587      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
588         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
589         and rename array obsSIce to exf_iceFraction.
590    o tutorial_deep_convection:
591      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
592        for now all in this exp. code dir.
593      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
594        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
595    o eesupp/src:
596      - added SINGLE_DISK_IO option because reading of parameter files on
597        very large number of processors did not work with existing set-up
598    
599    checkpoint64o (2013/09/25)
600    o pkg/atm_phys & atm_compon_interf:
601      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
602    o tools/build_options:
603      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
604        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
605        remove CPP setting (was identical to genmake2 default).
606    o pkg/gmredi & model/src: Some updating and work done on the residual model.
607      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
608      - fixed up the calculation of the eddy stress and how it is added to the
609        external forcing via taueddy_external_forcing.F
610      - at the moment, it is very experimental and only works with the variable eddy
611        diffusivity calculated in gmredi_k3d.F
612    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
613        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
614    o testreport (& tools/do_tst_2+2):
615      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
616    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
617      - remove CPP='cpp -traditional -P' (this is genmake2 default)
618      - add switch (for big setups) to use 'medium' memory-model (but leave it
619        commented out for now). Note: needed with FC 19 to compile big setups.
620    o pkg/atm_compon_interf:
621      - regroup per field origin (model & pkgs) the coupling storage routines
622         (which accumalate in time each coupling field)
623      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
624        update accordingly + simplify aim_do_physics.F
625    
626    checkpoint64n (2013/08/26)
627    o pkg/bbl:
628      - update formulation to reduce dispersion of tracer properties in bbl
629      - replaced horizontal and vertical transport parameters with velocities
630      - changes results for verification/global_with_exf.yearly
631    o verification/halfpipe_streamice:
632      - change to matrix construction; update both Fwd & AD output.
633    o verification/tutorial_tracer_adjsens:
634      - OpenAD test: switch to vector-invariant momentum since fluxform with
635        rStar causes problems with OpenAD; update output.
636    o tools:
637      - genmake2: define a common prefix for all temp-file names ; move them
638        to local /tmp disk (but would be easy to move them back);
639      - xmakedepend: apply the same switch for temp-files.
640    o pkg/offline:
641      - changes for use with rStar (NLFS): assume that we continue to provide
642        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
643        output files) and apply r* scaling at each time-step (function of the time
644        varying Eta field); use normal pickup files (needed for restart with NLFS).
645    o adjoint with OpenAD:
646      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
647        package openad.  This package has to be compiled for all runs with OpenAD
648        instead of specifying code_oad_all as a modification directory.
649      - link the fortran templates from tools/OAD_support to the build directory
650        for preprocessing to avoid conflicts between different setups compiled
651        simultaneously and simplify cleanup.
652    o pkg/exf:
653      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
654        main model or other pkgs are exchanged in EXF_MAPFIELDS).
655    o model/src:
656      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
657        (similar to do_fields_blocking_exchanges.F).
658    o tools/genmake2:
659      - remove TAF output src code just before calling staf (when not doing a fresh
660        built, will stop if things go wrong with staf).
661      - fix target "adobj" (left from TAF version-2 transition)
662    o pkg/diagnostics:
663      - add a parameter to track the status of pkg/diagnostics activation;
664        this replace/extend the use of logical param "settingDiags" (to check
665        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
666        New S/R to print error message and stop when pkgStatus is not right.
667      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
668    
669    checkpoint64m (2013/08/13)
670    o model/inc:
671      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
672        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
673    o pkg/kpp & aim_v23:
674      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
675    o pkg/seaice:
676      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
677        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
678      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
679    o eesupp/src:
680      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
681        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
682    o switch to TAF version-2:
683      - add flow directives to "freeze" naming convention for ad-routines that
684        are used in I/O routines of adjoint state and associated common blocks
685        that are used in adcommon.h (backward compatible with version-1)
686      - update all ad-optfiles (in tools/adjoint_options + few local to some
687        verification exp) to switch to latest TAF version (currently 2.5.5);
688        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
689        out except for diva).
690      - the major change with TAF version-2 is that both the differentiated
691        routines and the forward routines (new) are returned as part of the TAF
692        output source code. Update genmake2 accordingly.
693      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
694        with version-2 when compared to TLM or FWD gradient); other experiments
695        output show minor changes (machine truncation level); update the few AD &
696        TLM output with 12 matching digits only (some prior to version-2 switch).
697    
698    checkpoint64l (2013/08/05)
699    o model/src:
700      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
701      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
702        when using TAF but only if using OpenAD.
703    o pkg/mom_common+fluxform+vecinv:
704      - always set horiz. viscosity arrays to background value before calling
705        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
706        only when using variable horiz. viscosity (useVariableVisc=T);
707      - simplify mom_vecinv.F (only 1 block for momViscosity).
708    o pkg/mom_common: variable horiz. viscosity in NH code
709      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
710        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
711      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
712        useBiharmonicVisc & useVariableVisc.
713      - fix old bug (already in 1rst implementation of variable horizontal viscosity
714        in calc_gw.F, version 1.27, 2006/06/20):
715        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
716        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
717      - change background horiz viscosity in vertical momentum (gW) to always be
718        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
719        any type of variable viscosity, e.g., viscAh/4Grid)
720      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
721        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
722        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
723        default viscAh,viscA4 is zero).
724    o model/src:
725      - extend length of drC & recip_drC from Nr to Nr+1.
726    o Divided Adjoint (DIVA) with MPI:
727      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
728      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
729        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
730    
731    checkpoint64k (2013/07/23)
732    o tools/OAD_support:
733      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
734        and remove it from genmake2.
735    o tools/build_options:
736      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
737        MPI_HEADER_FILES list (let genmake2 find the missing headers)
738    o verification/halfpipe_streamice:
739      - change to driving stress formulation; update both Fwd & AD output.
740    o tools/genmake2 and Divided Adjoint with MPI:
741      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
742      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
743      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
744        Makefile, which is set by genmake2, and check which mpi-headers are needed.
745        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
746      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
747    o testreport:
748      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
749        perform additional runs (number of additional runs is "add_DIVA_runs" taken
750        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
751    o verification/lab_sea (AD test):
752      - change to test Divided Adjoint Run in this set-up (both standard AD test
753        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
754    o pkg atm_ & ocn_compon_interf:
755      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
756        staggerTimeStep implementation) and disable (retired) corresponding
757        parameter.
758    o pkg/offline:
759      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
760      - add S/R OFFLINE_CHECK to print offline parameter summary
761        and stop if loading a file that is not used;
762      - enable to calculate GMRedi tensor, KPP mixing and convective index
763        when the corresponding file(s) is/are not specified (but pkg is used).
764      - comment out resetting of monitorFreq (to endTime) since it still useful
765        for monitoring CFL numbers and checking offline fields.
766    o OpenAD:
767      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
768        smaller standard output) and generate new (smaller) output (on baudelaire
769        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
770    o model/src:
771      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
772        (where external_forcing_adjust was called) and change list of arguments;
773      - merge external_forcing_adjust.F into external_forcing_surf.F
774      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
775        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
776        previously in file "balance_relax.F", now removed); remove corresponding
777        arrays in FFIELDS.h.
778      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
779        a hack for getting back surfaceForcingS (loaded from file) when using
780        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
781      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
782        (was getting only 11 digits for AD-grad, due to different truncation
783         error in AD code).
784    
785    checkpoint64j (2013/07/04)
786    o pkg/offline:
787      - to enable the use of other features with pkg offline (e.g., obcs),
788        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
789      - comment out "allowFreezing" (now active) in 2 offline testing exp.
790    o pkg/exf ALLOW_RUNOFTEMP
791      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
792      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
793      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
794    o pkg/atm_phys:
795      - allows to add some damping on uVel,vVel (strength only function of k).
796    o verification, ad-tests:
797      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
798        global_ocean_ebm and offline_exf_seaice.thsice.
799    o verification/halfpipe_streamice:
800      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
801        flux input boundary conditions to be ignored; a fix for this bug changed
802        verification results for forward test.
803      - add adjoint test.
804    o pkg/ptracers:
805      - allow to restart without SOM pickup (resetting SOM to zero).
806    o pkg/gmredi:
807      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
808      - It uses mixing length theory and suppression by steering level effects to
809        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
810        to JPO, for more details).
811      - It also uses the diffusivity to calculate an eddy induced streamfunction
812        based on a PV closure (rather than a buoyancy closure as in GM).
813      - New files added to pkg/gmredi:
814        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
815          induced overturning streamfunction (called from gmredi_calc_tensor)
816        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
817          for use in gmredi_k3d
818        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
819          the eddy diffusivity
820    
821    checkpoint64i (2013/06/18)
822    o pkg/cheapaml:
823      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
824        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
825        with pkg/cheapaml.
826    o utils/python: add subpackage for cubed sphere function, first example is
827        simple cs.pcol to plot 2D fields on a map
828    o pkg/streamice:
829      - This is a new package in MITgcm, which solves dynamic equations for ice
830         sheets and ice streams
831      - At the moment it is independent of atmosphere/ocean dynamics, or any
832        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
833        ed that this will change)
834      - There is a new verification exercise that tests it, halfpipe_streamice,
835        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
836        rectangular embayment
837      - halfpipe_streamice is forward-only for now, will have TAF test soon
838      - for questions, email dgoldber@mit.edu
839    o pkg/thsice:
840      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
841        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
842      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
843         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
844      - allow precip from pkg/cheapaml to make snow over seaice.
845    o pkg/cfc:
846      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
847      - remove atmos CFC 2-D arrays from common bloc (now local variables)
848      - change some hard-coded constant to run time parameter for reading and
849        and interpolating atmospheric CFC ; keep same default as previously.
850      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
851      - put arguments in standard order: myTime, myIter, myThid
852      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
853        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
854      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
855      - new routine to print summary of CFC params and check for consistency.
856    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
857      similar to thsice_advdiff.
858      Note that for the B-grid case the routine parameters uc/vc are overwritten.
859    o pkg/cfc:
860      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
861        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
862      - fix interpolation of atmphspheric CFC between Sorthern and Northern
863        hemisphere value.
864    o pkg/seaice:
865      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
866    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
867                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
868      - requires an additional time level that is stored in the pickup
869      - you can start with AB2 from a pickup without this time level with
870        pickupStrictlyMatch = .false.
871    
872    checkpoint64h (2013/05/26)
873    o pkg/cheapaml:
874      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
875        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
876      - consistent treatment of uWind,vWind location: assume everywhere in
877        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
878        (Note: was already the case for Tair,Qair advection);
879        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
880      - compute diabatic forcing only in the interior (excluding overlap regions)
881      - fill in array "Qsw" (for short-wave heating);
882      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
883        before any update (consistent with MITgcm state var diagnostics);
884      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
885        non periodic ; + adjusted for uWind,vWind (C-grid).
886    o pkg/seaice:
887      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
888        add explicitly pkg/exf in experiments that currently use pkg/seaice.
889      - allows to compile pkg/seaice without pkg/exf.
890    o tools/OAD_support:
891      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
892        of array "ourStepOf" in function rvNextAction (revolve.F90).
893    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
894      - change pkg name (to be used with other atmospheric physics pkg)
895        but by-pass CVS when making the new pkg so that we keep the CVS history.
896    o pkg/offline:
897      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
898        (previously called from pkg/dic_surfforcing_init.F)
899    o model/src:
900      - re-order sequence of calls within packages_init_variables.F, using
901        standard order, except for:
902         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
903         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
904    o new pkg: atm_phys
905      - add entry point and source code (previously in contrib
906          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
907        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
908      - re-order sequence of calls within packages_readparms.F,
909         packages_init_fixed.F and packages_write_pickup.F
910        (but skip packages_init_variables.F because of TAF issues).
911      - update contrib/*/atm_gray/ experiment.
912    o pkg/seaice (ITD code):
913      - simplify and fix the writing of pickup-files for ITD case
914    o pkg/seaice (ITD code):
915      - introduce floe size dependent lateral melt for ITD case;
916      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
917      - update seaice_itd experiment main output.
918    o pkg/thsice:
919      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
920        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
921        changed accordingly pkg/atm2d.
922    
923    checkpoint64g (2013/05/01)
924    o pkg/exf ALLOW_RUNOFTEMP
925      - if defined,  river and glacier runoff temperature can be read-in from
926        runoftempfile; runoftempfile needs to have same format as runofffile
927    o pkg/thsice (& pkg/bulk_force):
928      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
929        for energy content of Precip + RunOff & Evap (like with pkg/exf).
930      - change computation domain to always be the interior (without overlap).
931      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
932    o verification/tutorial_global_oce_biogeo:
933      - add preliminary OpenAD setup (still has problems)
934    o pkg/seaice:
935      - turn some parameters for choosing the convergence criterion of
936        the inexact Newton method (JFNK) into runtime parameters for convenience
937      - clean up seaice_calc_viscosities.F: remove/retire two options for
938        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
939        the results of lab_sea/input because a division has been replaced by
940        a multiplication with the reciprocal (sumNorm)
941      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
942        convergence of solver (changes results, of course), and to test some
943        new features
944    o model/src:
945      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
946      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
947      - move forcing adjustment (balancing surface forcing) in specific S/R
948        where might also be applied exchanges (if needed) to forcing arrays.
949    o pkg/shelfice:
950      - allow to specify the Ice-Shelf mass per unit area (instead of
951        shelficeLoadAnomaly) and do the conversion from one to the other
952      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
953        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
954        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
955        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
956      - update isomip experiment forward output (get machine truncation error
957        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
958    o verification/offline_exf_seaice:
959      revise data.seaice in input.thermo and input_ad and update results accordingly
960        HO = 0.2, SEAICE_areaLossFormula = 2,
961        SEAICE_growMeltByConv = .TRUE.,
962        SEAICE_doOpenWaterMelt = .TRUE.,
963      Improve consistency with input.thsice and fix the spurious 500m ice corners
964    o verification/global_ocean.cs32x15:
965      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
966        in icedyn (thsice+seaice-dyn) test and update output.
967    o verification/offline_exf_seaice:
968      - adjust list of tested variables (with testreport) and update
969        standard test output with better slection of monitored fields.
970    o pkg/cd_code:
971      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
972        experiment lab_sea.hb87
973    o tools/genmake2:
974      - change default makedepend from the system default to tools/xmakedepend:
975        When no makedepend is specified, select tools/xmakedepend it the test pass,
976        otherwise select the system default (if exist and pass the test) or
977        try to build cyrus-makedepend ; stop if none of the 3 works.
978    o pkg/exf & pkg/thsice:
979      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
980        for energy content of Precip + RunOff & Evap. Assumes:
981       1) Rain has same temp as Air.
982       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
983       3) Run-Off comes at the temp of surface water (with same Cp)
984       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
985        put directly into Latent Heat flux & should use water-vapor heat capacity.
986       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
987        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
988    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
989        (compile when SEAICE_ALLOW_JFNK is defined)
990    o pkg/thsice:
991      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
992        implementation): move THSICE_AVE call after the advection (called directly
993        from thsice_do_advect.F).
994    o verification/global_ocean.90x40x15 and OpenAD:
995      New experiment for OpenAD is identical to the one in input_ad except that
996        multiDimAdvection=.FALSE.,
997      There is still an issue with this.
998    o pkg/thsice:
999      - account for ice velocity (ocean relative velocity) in turbulent heat flux
1000        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
1001        and offline_exf_seaice (main test).
1002    
1003    checkpoint64f (2013/03/31)
1004    o verification/OpenAD:
1005      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
1006    o verification/isomip, pkg/shelfice and OpenAD:
1007      - add OpenAD setup to this exp and make shelfice package work with OpenAD
1008    o verification/tutorial_global_oce_biogeo:
1009      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
1010    o verification/offline_exf_seaice:
1011      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
1012    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
1013      - add OpenAD setup to this exp and make ptracers package work with OpenAD
1014    o pkg/seaice/seaice_evp.F:
1015       mask the asymmetric contribution of the ice-ocean stress (when
1016       the turningAngle is non-zero) over open water to avoid stripes
1017       in the EVP-solutions after many EVP-substeps. This does not change
1018       the verification experiment (because turningAngle=0 in that experiment),
1019       but will affect other EVP solutions with turningAngle.ne.0
1020    o verification, AD & TLM output:
1021      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
1022        additions and multiplications which affect results at machine truncation
1023        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
1024        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
1025        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
1026        digits of matching.
1027    o pkg/seaice:
1028       modify lsr-algorithm so that it vectorizes AND converges by using a
1029       "zebra" method: split vector loop into two with step size 2; this
1030       solves a general convergence problem for the JFNK solver on a vector
1031       computer. It has the potential to even improve convergence for
1032       non-vector machines, but it does change the results so it is turned
1033       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
1034       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
1035    
1036    checkpoint64e (2013/03/05)
1037    o pkg/ecco and several verification experiments:
1038       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
1039       from ecco package, and revert to unified routine in model/src/
1040       Adjust verification experiments accordingly, especially gloal_oce_llc90
1041       Should conclude long-standing work by Gael to reconsile the_main_loop with
1042       ECCO and will enable OpenAD's revolve loop in ECCO setup.
1043    o pkg/generic_advdiff:
1044      - implement compressible flow method for multi-dim advection (similar to
1045        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
1046        TAF generates many recomputations) to use it; no yet coded with implicit
1047        vertical advection.
1048      - change experiment advect_cs (new output) and advect_xy (same output)
1049        to test compressible flow multi-dim advection.
1050    o pkg/generic_advdiff:
1051      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
1052        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
1053    o pkg/seaice:
1054      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
1055        bug affects two verification experiments (lab_sea and lab_sea.hb87),
1056        recover old (wrong) results by setting noSlipFac = 2. in
1057        seaice_calc_strainrates.F;
1058      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
1059      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
1060        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
1061      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
1062    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
1063      - new subroutines seaice_lsr_tridiagu/v
1064      - introduce loop bounds i/jmin/max to be able to use a restricted
1065        additive Schwarz method, but not used for now.
1066      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
1067      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
1068    o OpenAD support
1069       Reorganize S/R call for overall time-stepping loop to facilitate
1070       OpenAD revolve loop replacement
1071       (new S/R main_do_loop.F)
1072    o model/src:
1073      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
1074      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
1075        ADAMS_BASHFORTH2.
1076    o pkg/cheapaml:
1077      - add new parameter (default=F, same as before) to disable full domain
1078        (including land) periodicity in X & Y dir.
1079      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
1080        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
1081        into single S/R CHEAPAML_TIMESTEP.
1082    
1083    checkpoint64d (2013/02/17)
1084    o pkg/monitor (angular momentum):
1085      - do not add Eta contribution to the total AM if using rigid-lid;
1086      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
1087      - horizontal discretisation: compute Zonal wind contribution separately for
1088        each component (instead of from cell centered averaged) and use the 4
1089        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
1090      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
1091        FreeSurf) if using vectorInvariant momentum.
1092    o model/src (horizontal grid):
1093      - move initialisation of all horizontal grid arrays to null value
1094        from specific horizontal grid S/R to main S/R INI_GRID;
1095      - add 2 new arrays to project model C-grid velocity on to zonal direction
1096        (similar to AngleCosC & -AngleSinC but at U and V point location) and
1097        compute them in S/R CALC_GRID_ANGLES.
1098    o pkg/seaice: replace a hard coded parameter by a runtime parameter
1099        SEAICE_JFNK_tolIter
1100    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
1101        preconditioner for JFNK (run LSR into the overlaps as far as possible,
1102        i.e OLx/y-2, but overwrite the solution in the overlaps)
1103      - extend loop range in seaice_calc_viscosity
1104      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
1105      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
1106      - slightly modify loops in tridiagonal solver lsr-preconditioner
1107      - by default remove the extra exchange in seaice_preconditioner with a
1108        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
1109      - modify offline_exf_seaice so that old results without RAS are reproduced
1110        for output.dyn_jfnk.txt
1111      in seaice_fgmres.F (unrelated to RAS)
1112      - add a cpp-flag option for a re-ordered mapping (potentially more
1113        efficient), but because this changes the results, turn it off by
1114        default
1115      - replace the save statement by local common blocks
1116    o utils/matlab:
1117      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
1118      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
1119        instead of local script "load_cs.m".
1120    o pkg/seaice:
1121      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
1122        to the scalarProductMetric and the unrolling. By chance this does not
1123        change the verification experiment, because of the particular domain
1124        decomposition
1125    o pkg/diagnostics:
1126      - change default missing_value from UNSET_RL to -999.
1127    o pkg/layers: improve vectorization of layers_fluxcalc.F
1128      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
1129        time spent in this routine by more than a factor of 3 on an NEC-SX8
1130      - step 2: replace search algorithm by a bisection algorithm found in
1131        Press et al. Numerical Recipes in Fortran. This algorithm can be
1132        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
1133        For now, use this algorithm only for TARGET_NEC_SX defined.
1134      - moved the search algorithm into a separate subroutine, that is kept
1135        within the same file for automatic inlining.
1136      - modified catching potential errors
1137    o pkg/ecco:
1138      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
1139    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
1140      - modifications for ALLOW_GENTIM2D_CONTROL
1141      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
1142      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
1143      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
1144      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
1145    o model/src:
1146      - account for moist thermodynamics in (dry) potential temperature equation;
1147        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
1148        and cpl_aim+ocn.
1149      - also switch to standard compiler (gfortran, was using ifort previously)
1150        for fizhi-cs experiments reference output.
1151    o pkg/ctrl:
1152      - 1st step toward generic time-varying control variable (2D) via CPP option
1153        ALLOW_GENTIM2D_CONTROL
1154      - note new namelist ctrl_nml_genarr in data.ctrl
1155    o verification/global_ocean.cs32x15:
1156      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
1157        thsice calling sequence and update "output.icedyn.txt" output file.
1158    o pkg/ptracers:
1159      - from Ryan A.: code to allow to restart a tracer at regular time interval
1160        specifying a reset frequency and a reset-phase (for each tracers).
1161    o pkg/thsice:
1162      - implement new sequence of calls for thsice+seaice:
1163          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
1164          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
1165      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
1166        in CPP_OPTIONS.h) to recover old sequence;
1167      - update diagnostics for Intermediate State thsice diagnostics: now filled
1168        just before advection (instead of just after advection in old sequence);
1169      - update output of experiment offline_exf_seaice (standard test);
1170      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
1171        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
1172    o pkg/aim_v23:
1173      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
1174      - use standard pkg/mdsio routines to read & write CO2 pickup file;
1175      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
1176      - Implement new sequence of calls for seaice advection (with thsice and
1177        seaice diffusion): do ice advection after ice-Thermodynamic (previously
1178        was done before); change aim_do_physics.F (split the bi,bj loops block);
1179      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1180    o pkg/thsice:
1181      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1182        where just seaice diffusion is used without seaice-dynamics.
1183    
1184    checkpoint64c (2013/01/18)
1185    o pkg/seaice:
1186      - add a parameter JFNKres_tFac that can replace JFNKres_t
1187        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1188      - add a line search option to the JFNK solver
1189      - move update of u/vIce and computation of initial residual into a separate
1190        routine (same file); makes the code a little easier to read (?)
1191      - the line search requires computation of the residual and for some reason
1192        I cannot do the update of u/vIce at the beginning of the Newton loop
1193        without changing the results, so we move computation of the new residual
1194        also to the end of the Newton loop, even without the line search
1195    o pkg/mdsio:
1196      - write missing value (corresponding to undefined array value) to meta files;
1197        skip this if missing value is one (UNSET_RL would be a better value for the
1198        case of undefined missing value but it's current the default missing-value);
1199        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1200    o pkg/exf & thsice:
1201      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1202        diagnostics) even when SHORTWAVE_HEATING is #undef;
1203    o verification/cfc_example:
1204      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1205        illustrate how to use it).
1206    o verification/offline_exf_seaice:
1207      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1208        files to only one time-record.
1209      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1210        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1211        snapshot output; same mcPheePiston value as in thsice with
1212        surf-current=0.2m/s.
1213      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1214        initial conditions).
1215    o verification/cfc_example:
1216      - update file "data" with more standard choice (default rotationPeriod,
1217        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1218        set deltaTFreeSurf to deltaTtracer) and update the output.
1219    o pkg/layers:
1220      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1221      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1222    o verification/offline_exf_seaice:
1223      - set all {field}period to zero for constant-in-time forcing (not tested
1224        anywhere else).
1225    o verification/offline_exf_seaice:
1226      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1227      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1228    o model/src:
1229      - implement Finite-Volume method for (hydrostatic) presure gradient
1230        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1231    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1232      - In order to be compatible with the default EVP code, this requires changing
1233        the EVP code around a little; and because any small change immediately
1234        breaks the lab_sea.hb87 verification experiment, the reference output is
1235        updated two times (each time the remaining aggrement was only 2 digits):
1236        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1237        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1238        The adjoint test lab_sea.evp also needed to be updated.
1239      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1240        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1241        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1242        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1243        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1244        kept obscure, because I need to test it a little more.
1245    o pkg/cheapaml:
1246      - fix few incorrect type (_RL/_RS) in subroutine calls.
1247    o pkg/seaice:
1248      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1249        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1250    o model/src:
1251      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1252        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1253        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1254    o pkg/cheapaml:
1255      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1256        update output of experiment cheapAML_box.
1257      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1258        and set them only in one place (cheapaml_readparms.F).
1259      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1260      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1261        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1262    o model/src/the_main_loop.F:
1263      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1264    o pkg/seaice:
1265      - remove legacy branch code.
1266      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1267    o verification/*/code*/SEAICE_OPTIONS.h:
1268      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1269        SEAICE_CAP_HEFF).
1270    o pkg/cheapaml:
1271      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1272        to load new forcing fields.
1273      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1274      - remove switch to "-r8" compiler option (no longer needed) in verification
1275        cheapAML_box, keep same output (small trucation error differences).
1276    o verification/offline_exf_seaice:
1277      - add thermodynamics only test.
1278    o verification/cheapAML_box:
1279      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1280        keep same output (same 14 digits for cg2d).
1281      - switch on "-r8" compiler option (some numerical values are missing
1282        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1283    
1284    checkpoint64b (2012/12/24)
1285    o pkg/cheapaml:
1286      - remove un-used variables (Qnet,EmPmR) from pickup files.
1287      - store tendency of advected variables into cheapaml pickup file
1288        and fix the AB-2 restart.
1289    o verification/offline_exf_seaice and lab_sea adjoint:
1290      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1291      - switch to 4 time steps in offline, consistent with lab_sea.
1292      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1293      - update results after change of experiment seaice.
1294    o pkg/seaice:
1295      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1296        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1297        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1298        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1299    o model/src:
1300      - add run-time parameter to select CG2D solver minimum-residual solution
1301        (in case of a poor convergence).
1302    o pkg/seaice/seaice_lsr.F
1303      - move calculation of matrix coefficients into new
1304        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1305        file; the main purpose of this change is to be able to reuse the code
1306        in S/R SEAICE_PRECONDITIONER
1307      - modify the computation of the residual so that the mass of sea-ice
1308        is not used twice; this simplifies the calculations, but since
1309        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1310        not tested in testreport---this does not affect the testreport results.
1311    o verification/seaice_obcs:
1312      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1313        verification/lab_sea/input.salt_plume; changes results/output.txt*
1314    o model/src:
1315      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1316    o pkg/seaice:
1317      - improve description of parameters in seaice_fgmres.F and start
1318        cleaning up the code
1319      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1320        second argument
1321      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1322        results of offline_exf_seaice.dyn_jfnk
1323      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1324    o pkg/aim_v23:
1325      - fix an other bug in dissipation heating (grid-cell area was missing).
1326    o model/src + pkg/seaice:
1327      - add global (multi-tile) linear solver for pair of tri-diagonal system
1328        along X and Y lines, respectively for U and V component.
1329        Note: 1) MPI and cube-exchange not yet coded.
1330            2) probably not accurate for poorly conditioned / large size problem.
1331      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1332        default: not compiled and not used.
1333    o pkg/seaice:
1334      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1335        introduce bi/bj loops and use global_sum_tile_rl instead of
1336        mpi_allreduce in seaice_fgmres.F
1337      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1338      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1339      - add a verification experiment for JFNK in offline_exf_seaice
1340    o verification:
1341      - change (for now, only fwd test) offline_exf_seaice experiment:
1342        use a re-entrant channel with idealized coastline (trapezoidal shape)
1343        at southern boundary to explore seaice dynamics and thermodynamics
1344        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1345        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1346      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1347    o pkg/exf:
1348      - disable "sstExtrapol" when Nr=1
1349    o verification:
1350      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1351        to test pkg/cheapaml.
1352    o pkg/aim_v23 & pkg/shap_filt:
1353      - fix dissipation heating (erroneous gravity multiplication factor).
1354    o pkg/seaice:
1355      - remove unused field pressPre from jfnk solver
1356      - rename two subroutines in seaice_preconditioner.F
1357    o eesupp/src:
1358       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1359    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1360       - remove wrong parts of the rhs and the lhs (were in there
1361         because I did not understand the concept of this preconditioner)
1362       - add an exchange between u- and v-sweep. This increases communication
1363         by a factor of two but improves the convergence of jfnk. Ideally,
1364         one would like the u- and v-sweep to be independent. So far within
1365         undocumented ifdefs
1366       - reorganize the extra computations for printing the residuals
1367    o tools/genmake2:
1368      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1369        since it's not necessary (and was preventing to use MNC in some cases).
1370    
1371    checkpoint64a (2012/11/16)
1372    o pkg/autodiff:
1373      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1374        autodiff_readparms.F no longer depends on calling order (within
1375        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1376        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1377        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1378    o pkg/obcs:
1379      - adding tidal velocity forcing capability to obcs
1380        for usage example, see verification/seaice_obcs/input.tides
1381    o pkg/seaice:
1382      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1383        SEAICE_LSRrelaxU/V
1384      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1385    o pkg/aim_v23:
1386      - implement heating from friction (bottom friction and stratospheric drag).
1387    o pkg/shap_filt:
1388      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1389        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1390    o model/src:
1391      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1392        time-constant addMass field from file (addMassFile);
1393      - support for heating due to friction (and Kinetic Energy dissipation):
1394        add option, run-time switch and 3-D field array + support code ; each pkg
1395        or S/R can add heating contribution (if there is a sink of KE); the sum is
1396        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1397    o pkg/seaice:
1398      - complete merge of ITD code into seaice_growth.F
1399        from MITgcm_contrib/torge/itd/code/
1400        no verification so far, but Torge Martin tested
1401        "1-D test case and Beaufort set up;
1402        deliver okay results after 1 model year."
1403      - complete merge of SEAICE_SIZE.h into all relevant routines
1404      - move computation of eta at Z-points into calc_viscosities
1405        + introduce global field etaZ
1406        + add different methods for computing etaZ, for now the old
1407          method (simple averages of eta to Z-points) is hardwired
1408        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1409          seaice_preconditioner
1410      - simplify computations for SEAICE_ZETA_SMOOTHREG
1411      - seaice_preconditioner:
1412        + replace one remaining press by pressLoc (mistake)
1413        + adjust printing of residuals
1414      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1415        + add (SEAICE.h) and rename some counters (initiliased in
1416          seaice_init_fixed.F)
1417        + add _BEGIN/END_MASTER (myThid)  around print statements
1418        + print total number of iterations and failures over SEAICE_monFreq
1419          interval to STDOUT
1420      - move control over output-messages by fgmres to seaice_jfnk to save
1421        some operations
1422      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1423        in order to make restarts with sol .ne. zero (fgmres with restarts)
1424        (seaice_jfnk.F, seaice_fgmres.F)
1425      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1426        a serious convergence problem when open boundaries are involved
1427    o pkg/ggl90: fix computation of control volumes for the case of
1428      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1429      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1430    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1431    o pkg/autodiff
1432      - Add inAdMode switch for SEAICEuseDYNAMICS:
1433        SEAICEuseDYNAMICSinAdMode
1434        (extend logic in ADAUTODIFF_INADMODE_SET)
1435    o pkg/seaice
1436      - Step 1 of merging ice-thickness distribution (ITD) code from
1437        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1438        The code implements concept laid out in Thorndike et al. (1975);
1439        code is enabled via CPP flag SEAICE_ITD
1440        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1441        code is not complete yet!!
1442      - SEAICE_SIZE.h now included in almost all seaice routines
1443    o verification (using seaice):
1444      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1445        global_ocean.cs32x15.seaice ; update results.
1446      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1447      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1448        offline_exf_seaice (previously compiling B-grid).
1449    o pkg/exf:
1450      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1451        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1452        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1453    o pkg/layers (adjust changes from Sept 19):
1454      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1455        this allows to remove "layers_maxNum" dimension from all layers arrays.
1456    o pkg/layers (adjust changes from Sept 19):
1457      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1458      - snap-shot extended to all type of layers (not just the 1rst type);
1459      - remove layers variables when corresponding CPP option is undef.
1460    o pkg/layers:
1461      - rename pkg/layers variable and add new output (layer exist & un-weighted
1462        velocity in layer)
1463    o pkg/seaice:
1464      - simplify (?) ocean-drag coefficent computations by using
1465        the same routine in all three solvers (saves some code lines)
1466      - remove global fields DRAGA and DRAGS from C-grid code and
1467        declare them locally in lsr.F (the only place where they are
1468        still used)
1469      - update AD output of lab_sea.evp (very sensitive anyway).
1470    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1471      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1472      and SEAICEuseJFNK=.true. A few things to note:
1473      - involves a FGMRES, that is parallel but very inefficient,
1474        because of many scalar products (global sums) in the Gram-Schmidt
1475        orthogonalization method. Needs to be replaced. Original code
1476        from J.-F. Lemieux
1477      - preconditioner for FGMRES is a stripped down version of LSOR
1478      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1479        preconditioner. For the preconditioner, the default is set to 10.
1480      - Jacobian times vector is computed with finite differences
1481      - marginally related to JFNK-solver: add a smooth regularization for
1482        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1483        2009) for any implicit solver (not implemented for EVP because EVP
1484        does not need this regularization in the first place). Define
1485        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1486    o eesupp/src:
1487      - check in genmake2 that intrinsic S/R flush is available.
1488      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1489      - flush standard & error msg unit before MPI termination
1490      - if debugMode, flush IO unit after printing msg
1491    o pkg/ctrl:
1492      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1493        to ctrl_set_unpack_xyz.
1494    
1495    checkpoint64 (2012/10/09)
1496    o pkg/shelfice
1497      - in mom_fluxform.F, mom_vecinv.F:
1498        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1499        Bug fix KappaRU -> KappaRV
1500        does not change verification/isomip but may change other setups
1501        (presumably constant KappaRU=KappaRV)
1502      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1503    o pkg/obcs:
1504      - fixed some indexing bugs in obcs_seaice_sponge.F
1505      - added obcs relaxation subroutines for HSALT and HSNOW
1506      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1507  o pkg/seaice:  o pkg/seaice:
1508    - add "multicategory" parameterization for snow in analogy to ice,    - add "multicategory" parameterization for snow in analogy to ice,
1509      default is off for now.      default is off for now.
