4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/kl10:
8      - add new pkg "kl10" for mixing due to internal wave breaking, from
9        http://www.sciencedirect.com/science/article/pii/S1463500310000144
10        (contribution from Jody Klymak), tested in verification experiment
11        verification/internal_wave/input.kl10/
12    o isomip experiment:
13      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
14        (input.htd) and update the output.
15    o cd_code experiments:
16      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
17        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
18        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
19        update the corresponding output.
20    o pkg/seaice:
21      - reduce the number of include files and store directives in
22        S/R seaice_lsr_tridiagu/v
23      - change the order of loops in one case in S/R seaice_lsr_tridiagv
24        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
25        get rid off one store directive (a TAF bug?)
26      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
27        S/R seaice_lsr_tridiagv to change the loop range for consistency
28      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
29      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
30        S/R seaice_lsr_tridiagu/v (requires update of
31        offline_exf_seaice/input.dyn_jfnk)
32    
33    checkpoint65a (2014/07/27)
34    o model/src:
35      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
36        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
37        (topo in p-coords, ice-shelf in z-coords); update output of experiments
38        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
39    o model/src:
40      - collect momentum forcing tendency into local 2-D array (passed as argument
41        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
42        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
43        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
44      - collect T & S forcing tendency into local 2-D array (passed as argument to
45        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
46        affects results at machine truncation level (e.g., ocean: if using
47        SHORTWAVE_HEATING and atmos:, if using FrictionHeating or (atm_Rq<>0)
48        moist correction due to vertical advection).
49      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
50        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
51        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
52        obcs_ctrl (ad & fwd grd @ 12 & 7).
53    o pkg/ptracers & diagnostics:
54      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
55        title (to avoid some unexpected truncation); sort out ptracers diags units.
56      - collect ptracer forcing tendency into local 2-D array (passed as argument
57        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
58    
59    checkpoint65 (2014/07/18)
60    o pkg/fizhi:
61      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
62        affects results at machine truncation level. Update output of experiments
63        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
64    o pkg/seaice: more clean up
65      - rename TAF common block tapes to be more consistent and remove
66        unnecessary duplicates
67      - add store directives to remove more recomputations, but use smaller
68        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
69        The idea behind this flag is to reduce the memory footprint when the
70        adjoint of the LSR is not required. As of now, defining the flag
71        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
72        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
73        For experiment offline_exf_seaice, this means on a linux box with gfortran
74        nearly a factor of 10 (but keep in mind there is mostly seaice code in
75        this experiment):
76        > size mitgcmuv_ad
77        text    data        bss     dec        hex  
78        5100659 1216  220458952  225560827  d71c8fb
79        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
80        but only a moderate increase of 36% for global_ocean.cs32x15:
81        text    data        bss     dec        hex
82        6695027 1648 1014578664 1021275339 3cdf6ccb
83        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
84      - note: there are still recomputations in global_ocean.cs32x15 and
85        offline_exf_seaice and the gradient agreement changes (gets a
86        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
87      - in general, the AD gradients still are wrong
88    o OpenAD
89      - clean up code_oad/ directories somewhat by moving files
90        dontCompile, dontTransform, keepOriginal to OAD_support/
91    o model/src:
92      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
93        (not currently tested): add dissipation terms before NLFS rescaling of
94        tendencies (previously done after).
95    o pkg/diagnostics:
96      - write stats-diags in ascii file with more digits (same as in monitor).
97    o pkg/down_slope:
98      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
99        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
100    o model/src:
101      - new file "apply_forcing.F" containing all the code previously in
102        external_forcing.F, but with new argument list: pass, as new argument,
103        the current level tendency array to update (instead of a direct update
104        of the common bloc array). Change the corresponding calls.
105      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
106        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
107    o pkg/seaice/seaice_lsr, a little bit of clean up
108      - rearrange some code blocks, so that now all calculations for
109        setting up the right-hand-sides done within one single block
110        (I find that easier to read and understand)
111      - rearrange freedrift-code to reduce the number of ifdefs
112      - adjust some indentations and comments
113    
114    checkpoint64z (2014/07/10)
115    o model/src and several pkgs:
116      - change argument list of all S/R called from external_forcing.F and
117        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
118        to pass, as argument, the current level tendency array to update
119        (instead of a direct update of the common bloc array).
120      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
121      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
122    o pkg/seaice/seaice_lsr.F
123      - always initialize local arrays in seaice_lsr_tridiagu/v
124      - add more local tapes to seaice_lsr_tridiagu/v
125      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
126        keep it in bi/bj loop; this seems to be essential
127      - gradients are still wrong but only by 4-7 orders of magnitude
128        instead of 15 orders of magnitude, lab_sea improves a little
129    o pkg/seaice
130      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
131        generates unnecessary code in seaice_lsr_ad
132      - add more store directives in seaice_lsr to avoid unnecessary code
133        in seaice_lsr_ad
134      - exclude some residual computations in seaice_lsr when
135        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
136        in seaice_lsr_ad
137      - add more storing, a new tape (model/src/the_main_loop.F) and
138        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
139        and klockey should be checked by a specialist)
140      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
141        and update lab_sea after previous changes in pkg/seaice below
142    o pkg/autodiff:
143      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
144        viscFacInAd : run time parameters allowing for adjoint switches
145        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
146    o pkg/ecco:
147      - introduce cost_gencost_boxmean.F that computes a box mean
148        temperature (for use in adjoint sensitivity studies).
149    o model/src/set_defaults.F : initialize viscFacAdj to 1.
150    o pkg/mom_common/mom_calc_visc.F:
151      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
152    o pkg/seaice/seaice_summary.F:
153      - statement for SEAICEadjMODE now in autodiff_readparms.F
154    o pkg/seaice:
155      - remove some store directives and add new ones in an effort to get
156        finally rid off the recomputation warnings. This is successful
157        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
158        defined (i.e. no extensive recomputation warnings left), but there
159        are still too many recomputations on the solver iteration level
160      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
161      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
162        SEAICE_SIZE.h
163      - add a store directive in S/R seaice_calc_viscosities
164    o pkg/seaice (ITD code):
165      - fix definition of Hlimit for multi-threaded case
166      - use double precision arithmetic to compute Hlimit: this affects results;
167        update output of experiment seaice_itd.
168    o replace content of verification/seaice_itd
169      - instead of a 1D column use the configuration of offline_exf_seaice
170        to test the ice thickness distribution code with ridging
171      - this is a first shot at this experiment
172      - change of some defaults of ridging parameters SEAICEhStar (from
173        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
174        and lot of new comments.
175    
176    checkpoint64y (2014/06/20)
177    o pkg/seaice/seaice_reg_ridge.F:
178      - modify the regularization of very small volumes of ice; only check
179        total volume HEFF, and do not apply correction to individual ice
180        classes because that leads to funny patterns in the heat and fw-fluxes
181        into the ocean. Adjust seaice_itd/results/output.txt
182      - replace nITD by SEAICE_multDim in loop-ranges
183    o pkg/exf:
184      - add code to process the case field period = -12. with UV interpolation.
185      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
186        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
187    o verification/global_with_exf:
188      - switch all fields period to -12. (was previously untested) in input/data.exf
189        (but keep secondary test ".yearly" unchanged); update the reference output.
190    o pkg/cal:
191      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
192    o pkg/exf:
193      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
194        to replace logical switch "exf_verbose"
195      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
196    o pkg/sbo:
197      - update from Katherine Quinn: evaluate mass directly from density and SSH
198        (budget using Finite Volume method) instead of from bottom pressure.
199      - allow testreport to collect few selected SBO output ; tested in exp.
200        global_ocean.90x40x15 (after updating the results, to include SBO output).
201      - fix some multi-threading issues (in output part).
202    o model/src & most packages:
203      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
204      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
205        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
206        "data.{pkg}" exist ; and leave the S/R (return) just after.
207      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
208        + call LAND_READPARMS from packages_readparms.F
209    o pkg/seaice:
210      - remove code that resets useThSice in S/R seaice_readparms and
211        replace it by a warning in S/R seaice_check
212      - remove parameter MULTDIM, replace with nITD and runtime
213        parameter SEAICE_multDim (still hard-wired to nITD if
214        SEAICE_ITD is defined)
215    
216    checkpoint64x (2014/05/24)
217    o verification/lab_sea:
218      - update adjoint and TLM output following changes to pkg/salt_plume
219      - un-do the update after putting back local recip_Cp in few places.
220    o pkg/salt_plume: modifications by An Nguyen:
221      - add capability to do brine rejection (salt-plume) as function of
222        volume+tracers (instead of only salinity tracer).
223      - conserve volume by exchanging volume from each kLev to above to
224        accommodate in-coming brine volume
225      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
226      - switch KPP surf buoyancy due to brine forcing to 3-d
227        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
228      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
229      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
230        in East/West Arctic.
231    o pkg/sbo:
232      - incorporate modifications from Katherine Quinn to enable the use of sbo
233        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
234        output for future testreport verification (unfinished).
235    o pkg/atm_phys:
236      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
237        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
238        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
239    o pkg/seaice
240      seaice_calc_ice_strength.F: modify expression to avoid divisions
241        (affects truncation)
242      seaice_do_ridging.F: clean up the insectarium
243      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
244      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
245      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
246      - add some debugging information and error messages (warnings)
247    o model/src: modifications relatd to atmosphere p*:
248      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
249      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
250        of vertical profile tRef in geopotential background and anomaly.
251      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
252        and pkg/atm_phys.
253      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
254        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
255    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
256    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
257        not used right now, but can be used in BGC packages to fix conservation.
258    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
259        other packages too.
260    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
261        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
262    o model/src:
263      - since we have several heat capacity (even in model/src), define "recip_Cp"
264        as local variable (no longer in common block) to avoid any confusion.
265      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
266    o pkg/exf:
267      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
268        air density as function of air Temp, Humidity and atm pressure.
269    
270    checkpoint64w (2014/05/02)
271    o verification:
272      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
273        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
274        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
275        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
276        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
277    o model/src: for atmosphere in p* coords:
278      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
279      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
280        but not yet activated.
281    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
282      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
283      - this changes the results (but not for any verification experiment, because
284        none tests this), but avoids having an extra field in the restart files
285    o pkg/seaice: remove global variable TICE (not needed)
286      - replace by TICES or local variable where necessary (cost_seaice_test,
287        seaice_diagnostics_state)
288      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
289      - use specific read/write routines for reading and writing individual leves
290        of a multilevel field
291    o pkg/ctrl & model/inc:
292      - move additional anomaly fields of control vars (related to options:
293         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
294        from DYNVARS.h into new header file: CTRL_FIELDS.h
295    o pkg/seaice: some small modifications to the ridging code
296      - make fw2ObyRidge a global variable and add the freshwater flux to
297        seaice_growth
298      - pass actual thickness from seaice_prepare_ridging, so that it is
299        computed only in one place and compute it in the same way as in
300        seaice_growth
301      - initialise more fields in seaice_do_ridging that where cause floating
302        point exceptions over land
303    o pkg/seaice: preparations for ridging code and first real ridging code
304      - move most of "PART 1" of S/R seaice_growth into a new and separate
305        S/R seaice_reg_ridge that will both regularize the state variable after
306        advection call the actual ridging routine;
307      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
308        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
309      - remove ridging code from seaice_advdiff
310      - clean up remaining part 1 of seaice_growth in an attempt to make it
311        more readable (this is probably subjective)
312      - call seaice_itd_redist once in the initialisation phase to have the initial
313        conditions in the correct category
314      - finally: add new ridging routine for ITD code
315    
316    checkpoint64v (2014/04/11)
317    o pkg/ecco:
318      - add runtime parameters mdt[start,end]date[1,2]
319      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
320    o pkg/seaice:
321      - make deltaC a global variable, so that it can be used in ridging code
322      - first step towards ridging: introduce new routines that compute
323        ice strength based on ridging parameters
324      - add diagnostic for HSNOWITD
325      - add opnWtrFrac as a global variable (required for ridging scheme)
326    o pkg/salt_plume + pkg/seaice/seaice_growth.F
327      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
328        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
329    o verification/hs94.1x64x5:
330      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
331      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
332    o autodiff:
333      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
334        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
335        For now, only in pkgs used in verification/hs94.1x64x5.
336      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
337        which are specific to TAF/TAMC).
338      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
339        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
340        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
341      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
342        building mitgcmuv_ad (make adAll).
343    o pkg/ecco:
344      - cost_gencost_seaicev4.F:
345         reformulate proxy cost as function of sst and local param SEAICE_freeze
346         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
347      - add stop statement if old names siv4-[sst,vol] are used
348      - add snapshots + cost reports for atmospheric longwave
349      - remove factor 0.1 in front of wtau[u,v]
350      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
351         ALLOW_TMI_SST_COST_CONTRIBUTION
352    o pkg/atm_phys:
353      - add some diagnostics for Short-wave and for convection S/R.
354    o pkg/seaice/seaice_growth:
355      - fix a bug in the lateral melt parameterization for SEAICE_ITD
356        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
357      - rearrange loop order for better vector code in the same code block
358      - rewrite the floeDiameter formula to have fewer divisions
359      -  (miraculously) none of this changes the results of seaice_itd
360    o pkg/smooth:
361      - move param smooth2Ddiffnbt to pkg/ecco
362    o pkg/salt_plume:
363      - salt_plume_frac.F:
364         clean up local param names
365         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
366    o pkg/rw:
367      - add RS version of S/R READ_MFLDS_LEV.
368    o pkg/streamice:
369      - fix the restart test by writing/reading pickup_streamice files.
370    o pkg/seaice:
371      - refine checks for jfnk-related parameters
372      - comment out if statement with SEAICEuseIMEX parameter as long as there
373        is no IMEX code to avoid confusion and surprises
374    
375    checkpoint64u (2014/03/07)
376    o verification/MLAdjust:
377      - rename secondary test suffix:
378         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
379         0.leithD -> AhFlxF  + switch to flux-form
380         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
381         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
382    o pkg/mom_vecinv:
383      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
384        to be before mom_calc_visc.F)
385      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
386      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
387        this is simpler for the adjoint and for diagnostics.
388    o model/src + pkg/momentum:
389      - add input files for  2-D additional Western and Southern cell-edge wall
390         (e.g., to add "thin-wall" where it is =1).
391      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
392        using 2nd hFacZ that is computed from initial (fix domain) hFac
393      - known limitations of thin wall implementation: not yet coded for sigma
394        coords; not working with CD-scheme neither.
395    o pkg/seaice:
396      - rename recently introduced parameters from (wrong name) AB to
397        BDF (backward difference time discretisation)
398      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
399    o tools/adjoint_options:
400      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
401    
402    checkpoint64t (2014/02/01)
403    o pkg/ecco
404      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
405        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
406      - replace hard-coded record number and period which only work for monthly
407        with read-in runtime param that works for other periods (month,day,year)
408    o pkg/thsice
409      - corrected store directive fixes thsice adjoint gradient checks
410    o genmake2 & testreport:
411      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
412        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
413        Update testreport accordingly. No need to set "export OPENAD=true"
414        in adjoint_options/adjoint_oad anymore (will be removed later).
415    o pkg/shelfice:
416      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
417        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
418        so that surface forcing applies to k=kSurf if using pkg/shelfice.
419    o pkg/ctrl, pkg/grdchk, pkg/ecco:
420      - Changes to make GENARR more modular (i.e. invisible if not used)
421    o model/src/temp_integrate.F and salt_integrate.F
422      - re-include store directives that were removed on Dec 27th.
423    o model/src/external_forcing_surf.F
424      - add storage directives for EmPmR and PmEpR to avoid recomputation of
425        seaice_model in the adjoint that is problematic when seaice_model is
426        turned off in the adjoint. The resolved issue dated back to July when
427        EXTERNAL_FORCING_SURF call was moved.
428        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
429    o pkg/exf/exf_check.F
430      - fix a small bug again (originally found by Wentao Liu, now found again)
431      - streamline error output
432    o pkg/streamice and aim_v23:
433      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
434        Apple's /usr/bin/cpp knows what to do:
435        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
436        Target: x86_64-apple-darwin13.0.0
437    
438    checkpoint64s (2014/01/05)
439    o tools/adjoint_options:
440      - switch to fastopt.net TAF server (instead of default fastopt.de) for
441        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
442    o model/src:
443      - remove some unnecessary TAF storage directives in forward_step.F and
444        in dynamics.F (note: not always removed by TAF, e.g., double storage
445        of kappaRU,kappaRV in former version of dynamics.F).
446    o model/src & pkg/ptracers:
447      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
448        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
449        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
450      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
451      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
452      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
453    o useSingleCpuInput separates single-CPU input from single-CPU output;
454        for now only implemented for in exf_interp_read.F
455    o verification/advect_xy:
456      - fix missing EXCH call in local version of ini_salt.F and update output.
457    o momentum diagnostics:
458      - fix which deltaT is used in Total-Tendency diagnostics.
459      - fix typo in diagnostics for momentum tendency from AB.
460    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
461        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
462    
463    checkpoint64r (2013/12/08)
464    o verification/*/results:
465      - Update reference output of experiments that were passing with just 13 digits
466         (make it easier to detect future changes in results)
467    o model/src & pkg/ptracers:
468      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
469        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
470        to inside ptracers_integrate.F ; remove ptracers_advection.F
471    o coupling interface pkgs:
472        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
473      - change the config check to test the agreement of Ocean Depth
474        with ATM land/sea mask (instead of ATM orography);
475      - send to coupler the number of coupler time-steps to do for this run:
476        this allows to check for consistency and don't need anymore to be
477        specified in parameter file "data";
478      in coupler:
479      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
480      - improve report to log-file of config setting (pass log-file unit to few S/R)
481    o pkg/compon_communic:
482      - add coupling send/receive for non-tiled integer vector;
483      - add S/R to check and stop if any proc has an error (similar to
484        eesupp/src/stop_if_error.F but single thread and across Comm_World).
485    o pkg/exch2:
486      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
487        through list of all tiles my proc owns.
488    o model/src:
489      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
490        from rTrans) to simplify dependencies (no need to store rTrans anymore in
491        calling S/R); this affects AD results at machine truncation level:
492        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
493        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
494    o tools/build_options:
495      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
496    o coupling interface pkgs:
497        [compon_communic, atm_compon_interf & ocn_compon_interf]
498      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
499        to each S/R that needs it; remove un-used variables.
500      - change component tile registration (cpl_register.F in both compon_interf
501        and mitcomponent_tile_register.F) to pass the full list of tiles
502        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
503      - with pkg/exch2: adopt the same convention used for I/O to define mapping
504        towards coupler global array (unless W2_useE2ioLayOut=F):
505         a) can now use different tiling between atm & ocn comp.
506         b) no needs to modify the run-Off map when changing tiling (was needed
507            even if using the same tiling between atm & ocn).
508         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
509            full land tiles); not yet tested.
510      - check for valid mapping from comp. tile to coupler global array
511      - improve report of tile registration results to log file.
512    o pkg/exch2:
513      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
514        tile-registration (CPL_REGISTER);
515      - activate (un-comment) definition and setting of "W2_tileIndex" list to
516        store the local bi,bj indices of each tile;
517      - also print bi,bj in local report to log file;
518      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
519        Jun 2009 modif of pkg/exch2).
520    o testing on baudelaire:
521      - run 2 tests at a time: no significant slow down (since enough cpu) and
522        get the full set of test done earlier
523      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
524    o model/src/thermodynamics.F and routines called from it:
525      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
526        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
527        velocity (outp) by adding bolus velocity.
528      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
529        mass transport from velocity + lateral grid cell area
530      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
531      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
532     in thermodynamics.F
533      - remove k from thermodynamics.F and move it to temp_integrate.F
534        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
535        loop).
536      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
537        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
538        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
539        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
540      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
541        global_ocean.90x40x15, tutorial_global_oce_biogeo and
542        tutorial_tracer_adjsens (+ TLM output).
543    o tools/OAD_support and (verification/*/) code_oad:
544      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
545        module conversion ; remove unneeded CPP_EEOPTIONS.h.
546      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
547        version (closer to model/inc/CPP_OPTIONS.h).
548    o model/src:
549      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
550        retired list of parameters (routine FREEZE has been replace by surface
551        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
552    o pkg/gmredi:
553      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
554        velocity (same scheme but affects machine truncation) for GM_AdvForm.
555      - update output of FWD experiments: front_relax.bvp,
556        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
557    
558    checkpoint64q (2013/11/17)
559    o verification:
560      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
561        tutorial_global_oce_biogeo and global_ocean.90x40x15.
562      - generate new output (growth & melt) for seaice_itd experiment after
563        updating the input pickup_seaice files (previously wrong).
564    o pkg/cost:
565      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
566        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
567        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
568          cannot be applied to var in common block).
569        o allows to get results independent of tile-per-proc setting (if using
570          slower GLOBAL_SUM_SEND_RECV option).
571      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
572        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
573        forward gradients: update output).
574      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
575        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
576    o pkg/mom_common:
577      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
578        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
579        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
580        ensure that all field value that are used are set.
581    o tutorial_deep_convection (smag3d):
582      - add missing scaling in mom_calc_smag_3d.F;
583      - set smag3D_coeff in input.smag3d such that results do not change.
584    o pkg/dic:
585      - change dic_cost.F to compute cost on each tile first and then apply
586        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
587        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
588      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
589    o eesupp/src & pkg/mdsio:
590      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
591        (from pkg/mdsio) since they are no longer used for tape IO.
592      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
593        (+ keep a copy in pkg/atm_ocn_coupler).
594    o verification/isomip:
595      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
596    o tools/build_options:
597      - optfile linux_amd64_ifort11, fast (no ieee) case:
598        to get a working restart for all experiments, add "-fp-model source"
599        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
600    
601    checkpoint64p (2013/10/20)
602    o pkg/autodiff:
603      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
604        criteria, return to simple (default) tape IO format.
605    o pkg/mdsio (+ eesupp/src):
606      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
607        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
608      - fix globalFile and singleCpuIO options using simpler global mapping.
609      - new pairs of scatter/gather vector S/R (one for each type, generated from
610        template) corresponding to simpler global mapping.
611      - adread_write.F: switch to new S/R (but leave old calls commented) and write
612        to globalFile when parameter globalFiles is set to True.
613      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
614    o pkg/autodiff:
615      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
616        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
617        missing, just add a STOP if array type do not match.
618    o pkg/exf:
619      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
620         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
621         and rename array obsSIce to exf_iceFraction.
622    o tutorial_deep_convection:
623      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
624        for now all in this exp. code dir.
625      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
626        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
627    o eesupp/src:
628      - added SINGLE_DISK_IO option because reading of parameter files on
629        very large number of processors did not work with existing set-up
630    
631    checkpoint64o (2013/09/25)
632    o pkg/atm_phys & atm_compon_interf:
633      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
634    o tools/build_options:
635      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
636        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
637        remove CPP setting (was identical to genmake2 default).
638    o pkg/gmredi & model/src: Some updating and work done on the residual model.
639      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
640      - fixed up the calculation of the eddy stress and how it is added to the
641        external forcing via taueddy_external_forcing.F
642      - at the moment, it is very experimental and only works with the variable eddy
643        diffusivity calculated in gmredi_k3d.F
644    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
645        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
646    o testreport (& tools/do_tst_2+2):
647      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
648    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
649      - remove CPP='cpp -traditional -P' (this is genmake2 default)
650      - add switch (for big setups) to use 'medium' memory-model (but leave it
651        commented out for now). Note: needed with FC 19 to compile big setups.
652    o pkg/atm_compon_interf:
653      - regroup per field origin (model & pkgs) the coupling storage routines
654         (which accumalate in time each coupling field)
655      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
656        update accordingly + simplify aim_do_physics.F
657    
658    checkpoint64n (2013/08/26)
659    o pkg/bbl:
660      - update formulation to reduce dispersion of tracer properties in bbl
661      - replaced horizontal and vertical transport parameters with velocities
662      - changes results for verification/global_with_exf.yearly
663    o verification/halfpipe_streamice:
664      - change to matrix construction; update both Fwd & AD output.
665    o verification/tutorial_tracer_adjsens:
666      - OpenAD test: switch to vector-invariant momentum since fluxform with
667        rStar causes problems with OpenAD; update output.
668    o tools:
669      - genmake2: define a common prefix for all temp-file names ; move them
670        to local /tmp disk (but would be easy to move them back);
671      - xmakedepend: apply the same switch for temp-files.
672    o pkg/offline:
673      - changes for use with rStar (NLFS): assume that we continue to provide
674        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
675        output files) and apply r* scaling at each time-step (function of the time
676        varying Eta field); use normal pickup files (needed for restart with NLFS).
677    o adjoint with OpenAD:
678      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
679        package openad.  This package has to be compiled for all runs with OpenAD
680        instead of specifying code_oad_all as a modification directory.
681      - link the fortran templates from tools/OAD_support to the build directory
682        for preprocessing to avoid conflicts between different setups compiled
683        simultaneously and simplify cleanup.
684    o pkg/exf:
685      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
686        main model or other pkgs are exchanged in EXF_MAPFIELDS).
687    o model/src:
688      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
689        (similar to do_fields_blocking_exchanges.F).
690    o tools/genmake2:
691      - remove TAF output src code just before calling staf (when not doing a fresh
692        built, will stop if things go wrong with staf).
693      - fix target "adobj" (left from TAF version-2 transition)
694    o pkg/diagnostics:
695      - add a parameter to track the status of pkg/diagnostics activation;
696        this replace/extend the use of logical param "settingDiags" (to check
697        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
698        New S/R to print error message and stop when pkgStatus is not right.
699      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
700    
701    checkpoint64m (2013/08/13)
702    o model/inc:
703      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
704        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
705    o pkg/kpp & aim_v23:
706      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
707    o pkg/seaice:
708      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
709        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
710      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
711    o eesupp/src:
712      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
713        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
714    o switch to TAF version-2:
715      - add flow directives to "freeze" naming convention for ad-routines that
716        are used in I/O routines of adjoint state and associated common blocks
717        that are used in adcommon.h (backward compatible with version-1)
718      - update all ad-optfiles (in tools/adjoint_options + few local to some
719        verification exp) to switch to latest TAF version (currently 2.5.5);
720        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
721        out except for diva).
722      - the major change with TAF version-2 is that both the differentiated
723        routines and the forward routines (new) are returned as part of the TAF
724        output source code. Update genmake2 accordingly.
725      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
726        with version-2 when compared to TLM or FWD gradient); other experiments
727        output show minor changes (machine truncation level); update the few AD &
728        TLM output with 12 matching digits only (some prior to version-2 switch).
729    
730    checkpoint64l (2013/08/05)
731    o model/src:
732      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
733      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
734        when using TAF but only if using OpenAD.
735    o pkg/mom_common+fluxform+vecinv:
736      - always set horiz. viscosity arrays to background value before calling
737        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
738        only when using variable horiz. viscosity (useVariableVisc=T);
739      - simplify mom_vecinv.F (only 1 block for momViscosity).
740    o pkg/mom_common: variable horiz. viscosity in NH code
741      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
742        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
743      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
744        useBiharmonicVisc & useVariableVisc.
745      - fix old bug (already in 1rst implementation of variable horizontal viscosity
746        in calc_gw.F, version 1.27, 2006/06/20):
747        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
748        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
749      - change background horiz viscosity in vertical momentum (gW) to always be
750        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
751        any type of variable viscosity, e.g., viscAh/4Grid)
752      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
753        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
754        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
755        default viscAh,viscA4 is zero).
756    o model/src:
757      - extend length of drC & recip_drC from Nr to Nr+1.
758  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
759    - genmake2: do not create local ./mpi_headers dir when no file to copy into.    - genmake2: do not create local ./mpi_headers dir when no file to copy into.
760    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
