4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice
8      - remove unnecessary u/vTmp from subroutine call of
9        seaice_lsr_tridiagu/v
10      - remove some store directives and add new ones in an effort to get
11        finally rid off the recomputation warnings. This is successful
12        for SEAICE_VECTORIZE_LSR defined (i.e. no extensive recomputation
13        warnings left), but there are still too many recomputations on the
14        solver iteration level
15      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
16        SEAICE_SIZE.h
17      - add a store directive in S/R seaice_calc_viscosities
18    o pkg/seaice (ITD code):
19      - fix definition of Hlimit for multi-threaded case
20      - use double precision arithmetic to compute Hlimit: this affects results;
21        update output of experiment seaice_itd.
22    o replace content of verification/seaice_itd
23      - instead of a 1D column use the configuration of offline_exf_seaice
24        to test the ice thickness distribution code with ridging
25      - this is a first shot at this experiment
26      - change of some defaults of ridging parameters SEAICEhStar (from
27        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
28        and lot of new comments.
29    
30    checkpoint64y (2014/06/20)
31    o pkg/seaice/seaice_reg_ridge.F:
32      - modify the regularization of very small volumes of ice; only check
33        total volume HEFF, and do not apply correction to individual ice
34        classes because that leads to funny patterns in the heat and fw-fluxes
35        into the ocean. Adjust seaice_itd/results/output.txt
36      - replace nITD by SEAICE_multDim in loop-ranges
37    o pkg/exf:
38      - add code to process the case field period = -12. with UV interpolation.
39      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
40        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
41    o verification/global_with_exf:
42      - switch all fields period to -12. (was previously untested) in input/data.exf
43        (but keep secondary test ".yearly" unchanged); update the reference output.
44    o pkg/cal:
45      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
46    o pkg/exf:
47      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
48        to replace logical switch "exf_verbose"
49      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
50    o pkg/sbo:
51      - update from Katherine Quinn: evaluate mass directly from density and SSH
52        (budget using Finite Volume method) instead of from bottom pressure.
53      - allow testreport to collect few selected SBO output ; tested in exp.
54        global_ocean.90x40x15 (after updating the results, to include SBO output).
55      - fix some multi-threading issues (in output part).
56    o model/src & most packages:
57      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
58      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
59        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
60        "data.{pkg}" exist ; and leave the S/R (return) just after.
61      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
62        + call LAND_READPARMS from packages_readparms.F
63    o pkg/seaice:
64      - remove code that resets useThSice in S/R seaice_readparms and
65        replace it by a warning in S/R seaice_check
66      - remove parameter MULTDIM, replace with nITD and runtime
67        parameter SEAICE_multDim (still hard-wired to nITD if
68        SEAICE_ITD is defined)
69    
70    checkpoint64x (2014/05/24)
71    o verification/lab_sea:
72      - update adjoint and TLM output following changes to pkg/salt_plume
73      - un-do the update after putting back local recip_Cp in few places.
74    o pkg/salt_plume: modifications by An Nguyen:
75      - add capability to do brine rejection (salt-plume) as function of
76        volume+tracers (instead of only salinity tracer).
77      - conserve volume by exchanging volume from each kLev to above to
78        accommodate in-coming brine volume
79      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
80      - switch KPP surf buoyancy due to brine forcing to 3-d
81        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
82      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
83      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
84        in East/West Arctic.
85    o pkg/sbo:
86      - incorporate modifications from Katherine Quinn to enable the use of sbo
87        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
88        output for future testreport verification (unfinished).
89    o pkg/atm_phys:
90      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
91        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
92        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
93    o pkg/seaice
94      seaice_calc_ice_strength.F: modify expression to avoid divisions
95        (affects truncation)
96      seaice_do_ridging.F: clean up the insectarium
97      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
98      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
99      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
100      - add some debugging information and error messages (warnings)
101    o model/src: modifications relatd to atmosphere p*:
102      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
103      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
104        of vertical profile tRef in geopotential background and anomaly.
105      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
106        and pkg/atm_phys.
107      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
108        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
109    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
110    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
111        not used right now, but can be used in BGC packages to fix conservation.
112    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
113        other packages too.
114    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
115        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
116    o model/src:
117      - since we have several heat capacity (even in model/src), define "recip_Cp"
118        as local variable (no longer in common block) to avoid any confusion.
119      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
120    o pkg/exf:
121      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
122        air density as function of air Temp, Humidity and atm pressure.
123    
124    checkpoint64w (2014/05/02)
125    o verification:
126      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
127        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
128        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
129        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
130        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
131    o model/src: for atmosphere in p* coords:
132      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
133      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
134        but not yet activated.
135    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
136      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
137      - this changes the results (but not for any verification experiment, because
138        none tests this), but avoids having an extra field in the restart files
139    o pkg/seaice: remove global variable TICE (not needed)
140      - replace by TICES or local variable where necessary (cost_seaice_test,
141        seaice_diagnostics_state)
142      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
143      - use specific read/write routines for reading and writing individual leves
144        of a multilevel field
145    o pkg/ctrl & model/inc:
146      - move additional anomaly fields of control vars (related to options:
147         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
148        from DYNVARS.h into new header file: CTRL_FIELDS.h
149    o pkg/seaice: some small modifications to the ridging code
150      - make fw2ObyRidge a global variable and add the freshwater flux to
151        seaice_growth
152      - pass actual thickness from seaice_prepare_ridging, so that it is
153        computed only in one place and compute it in the same way as in
154        seaice_growth
155      - initialise more fields in seaice_do_ridging that where cause floating
156        point exceptions over land
157    o pkg/seaice: preparations for ridging code and first real ridging code
158      - move most of "PART 1" of S/R seaice_growth into a new and separate
159        S/R seaice_reg_ridge that will both regularize the state variable after
160        advection call the actual ridging routine;
161      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
162        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
163      - remove ridging code from seaice_advdiff
164      - clean up remaining part 1 of seaice_growth in an attempt to make it
165        more readable (this is probably subjective)
166      - call seaice_itd_redist once in the initialisation phase to have the initial
167        conditions in the correct category
168      - finally: add new ridging routine for ITD code
169    
170    checkpoint64v (2014/04/11)
171    o pkg/ecco:
172      - add runtime parameters mdt[start,end]date[1,2]
173      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
174    o pkg/seaice:
175      - make deltaC a global variable, so that it can be used in ridging code
176      - first step towards ridging: introduce new routines that compute
177        ice strength based on ridging parameters
178      - add diagnostic for HSNOWITD
179      - add opnWtrFrac as a global variable (required for ridging scheme)
180    o pkg/salt_plume + pkg/seaice/seaice_growth.F
181      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
182        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
183    o verification/hs94.1x64x5:
184      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
185      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
186    o autodiff:
187      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
188        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
189        For now, only in pkgs used in verification/hs94.1x64x5.
190      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
191        which are specific to TAF/TAMC).
192      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
193        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
194        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
195      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
196        building mitgcmuv_ad (make adAll).
197    o pkg/ecco:
198      - cost_gencost_seaicev4.F:
199         reformulate proxy cost as function of sst and local param SEAICE_freeze
200         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
201      - add stop statement if old names siv4-[sst,vol] are used
202      - add snapshots + cost reports for atmospheric longwave
203      - remove factor 0.1 in front of wtau[u,v]
204      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
205         ALLOW_TMI_SST_COST_CONTRIBUTION
206    o pkg/atm_phys:
207      - add some diagnostics for Short-wave and for convection S/R.
208    o pkg/seaice/seaice_growth:
209      - fix a bug in the lateral melt parameterization for SEAICE_ITD
210        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
211      - rearrange loop order for better vector code in the same code block
212      - rewrite the floeDiameter formula to have fewer divisions
213      -  (miraculously) none of this changes the results of seaice_itd
214    o pkg/smooth:
215      - move param smooth2Ddiffnbt to pkg/ecco
216    o pkg/salt_plume:
217      - salt_plume_frac.F:
218         clean up local param names
219         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
220    o pkg/rw:
221      - add RS version of S/R READ_MFLDS_LEV.
222    o pkg/streamice:
223      - fix the restart test by writing/reading pickup_streamice files.
224    o pkg/seaice:
225      - refine checks for jfnk-related parameters
226      - comment out if statement with SEAICEuseIMEX parameter as long as there
227        is no IMEX code to avoid confusion and surprises
228    
229    checkpoint64u (2014/03/07)
230    o verification/MLAdjust:
231      - rename secondary test suffix:
232         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
233         0.leithD -> AhFlxF  + switch to flux-form
234         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
235         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
236    o pkg/mom_vecinv:
237      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
238        to be before mom_calc_visc.F)
239      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
240      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
241        this is simpler for the adjoint and for diagnostics.
242    o model/src + pkg/momentum:
243      - add input files for  2-D additional Western and Southern cell-edge wall
244         (e.g., to add "thin-wall" where it is =1).
245      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
246        using 2nd hFacZ that is computed from initial (fix domain) hFac
247      - known limitations of thin wall implementation: not yet coded for sigma
248        coords; not working with CD-scheme neither.
249    o pkg/seaice:
250      - rename recently introduced parameters from (wrong name) AB to
251        BDF (backward difference time discretisation)
252      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
253    o tools/adjoint_options:
254      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
255    
256    checkpoint64t (2014/02/01)
257    o pkg/ecco
258      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
259        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
260      - replace hard-coded record number and period which only work for monthly
261        with read-in runtime param that works for other periods (month,day,year)
262    o pkg/thsice
263      - corrected store directive fixes thsice adjoint gradient checks
264    o genmake2 & testreport:
265      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
266        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
267        Update testreport accordingly. No need to set "export OPENAD=true"
268        in adjoint_options/adjoint_oad anymore (will be removed later).
269    o pkg/shelfice:
270      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
271        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
272        so that surface forcing applies to k=kSurf if using pkg/shelfice.
273    o pkg/ctrl, pkg/grdchk, pkg/ecco:
274      - Changes to make GENARR more modular (i.e. invisible if not used)
275    o model/src/temp_integrate.F and salt_integrate.F
276      - re-include store directives that were removed on Dec 27th.
277    o model/src/external_forcing_surf.F
278      - add storage directives for EmPmR and PmEpR to avoid recomputation of
279        seaice_model in the adjoint that is problematic when seaice_model is
280        turned off in the adjoint. The resolved issue dated back to July when
281        EXTERNAL_FORCING_SURF call was moved.
282        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
283    o pkg/exf/exf_check.F
284      - fix a small bug again (originally found by Wentao Liu, now found again)
285      - streamline error output
286    o pkg/streamice and aim_v23:
287      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
288        Apple's /usr/bin/cpp knows what to do:
289        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
290        Target: x86_64-apple-darwin13.0.0
291    
292    checkpoint64s (2014/01/05)
293    o tools/adjoint_options:
294      - switch to fastopt.net TAF server (instead of default fastopt.de) for
295        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
296    o model/src:
297      - remove some unnecessary TAF storage directives in forward_step.F and
298        in dynamics.F (note: not always removed by TAF, e.g., double storage
299        of kappaRU,kappaRV in former version of dynamics.F).
300    o model/src & pkg/ptracers:
301      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
302        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
303        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
304      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
305      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
306      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
307    o useSingleCpuInput separates single-CPU input from single-CPU output;
308        for now only implemented for in exf_interp_read.F
309    o verification/advect_xy:
310      - fix missing EXCH call in local version of ini_salt.F and update output.
311    o momentum diagnostics:
312      - fix which deltaT is used in Total-Tendency diagnostics.
313      - fix typo in diagnostics for momentum tendency from AB.
314    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
315        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
316    
317    checkpoint64r (2013/12/08)
318    o verification/*/results:
319      - Update reference output of experiments that were passing with just 13 digits
320         (make it easier to detect future changes in results)
321    o model/src & pkg/ptracers:
322      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
323        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
324        to inside ptracers_integrate.F ; remove ptracers_advection.F
325    o coupling interface pkgs:
326        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
327      - change the config check to test the agreement of Ocean Depth
328        with ATM land/sea mask (instead of ATM orography);
329      - send to coupler the number of coupler time-steps to do for this run:
330        this allows to check for consistency and don't need anymore to be
331        specified in parameter file "data";
332      in coupler:
333      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
334      - improve report to log-file of config setting (pass log-file unit to few S/R)
335    o pkg/compon_communic:
336      - add coupling send/receive for non-tiled integer vector;
337      - add S/R to check and stop if any proc has an error (similar to
338        eesupp/src/stop_if_error.F but single thread and across Comm_World).
339    o pkg/exch2:
340      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
341        through list of all tiles my proc owns.
342    o model/src:
343      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
344        from rTrans) to simplify dependencies (no need to store rTrans anymore in
345        calling S/R); this affects AD results at machine truncation level:
346        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
347        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
348    o tools/build_options:
349      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
350    o coupling interface pkgs:
351        [compon_communic, atm_compon_interf & ocn_compon_interf]
352      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
353        to each S/R that needs it; remove un-used variables.
354      - change component tile registration (cpl_register.F in both compon_interf
355        and mitcomponent_tile_register.F) to pass the full list of tiles
356        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
357      - with pkg/exch2: adopt the same convention used for I/O to define mapping
358        towards coupler global array (unless W2_useE2ioLayOut=F):
359         a) can now use different tiling between atm & ocn comp.
360         b) no needs to modify the run-Off map when changing tiling (was needed
361            even if using the same tiling between atm & ocn).
362         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
363            full land tiles); not yet tested.
364      - check for valid mapping from comp. tile to coupler global array
365      - improve report of tile registration results to log file.
366    o pkg/exch2:
367      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
368        tile-registration (CPL_REGISTER);
369      - activate (un-comment) definition and setting of "W2_tileIndex" list to
370        store the local bi,bj indices of each tile;
371      - also print bi,bj in local report to log file;
372      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
373        Jun 2009 modif of pkg/exch2).
374    o testing on baudelaire:
375      - run 2 tests at a time: no significant slow down (since enough cpu) and
376        get the full set of test done earlier
377      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
378    o model/src/thermodynamics.F and routines called from it:
379      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
380        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
381        velocity (outp) by adding bolus velocity.
382      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
383        mass transport from velocity + lateral grid cell area
384      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
385      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
386     in thermodynamics.F
387      - remove k from thermodynamics.F and move it to temp_integrate.F
388        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
389        loop).
390      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
391        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
392        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
393        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
394      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
395        global_ocean.90x40x15, tutorial_global_oce_biogeo and
396        tutorial_tracer_adjsens (+ TLM output).
397    o tools/OAD_support and (verification/*/) code_oad:
398      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
399        module conversion ; remove unneeded CPP_EEOPTIONS.h.
400      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
401        version (closer to model/inc/CPP_OPTIONS.h).
402    o model/src:
403      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
404        retired list of parameters (routine FREEZE has been replace by surface
405        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
406    o pkg/gmredi:
407      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
408        velocity (same scheme but affects machine truncation) for GM_AdvForm.
409      - update output of FWD experiments: front_relax.bvp,
410        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
411    
412    checkpoint64q (2013/11/17)
413    o verification:
414      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
415        tutorial_global_oce_biogeo and global_ocean.90x40x15.
416      - generate new output (growth & melt) for seaice_itd experiment after
417        updating the input pickup_seaice files (previously wrong).
418    o pkg/cost:
419      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
420        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
421        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
422          cannot be applied to var in common block).
423        o allows to get results independent of tile-per-proc setting (if using
424          slower GLOBAL_SUM_SEND_RECV option).
425      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
426        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
427        forward gradients: update output).
428      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
429        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
430    o pkg/mom_common:
431      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
432        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
433        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
434        ensure that all field value that are used are set.
435    o tutorial_deep_convection (smag3d):
436      - add missing scaling in mom_calc_smag_3d.F;
437      - set smag3D_coeff in input.smag3d such that results do not change.
438    o pkg/dic:
439      - change dic_cost.F to compute cost on each tile first and then apply
440        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
441        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
442      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
443    o eesupp/src & pkg/mdsio:
444      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
445        (from pkg/mdsio) since they are no longer used for tape IO.
446      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
447        (+ keep a copy in pkg/atm_ocn_coupler).
448    o verification/isomip:
449      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
450    o tools/build_options:
451      - optfile linux_amd64_ifort11, fast (no ieee) case:
452        to get a working restart for all experiments, add "-fp-model source"
453        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
454    
455    checkpoint64p (2013/10/20)
456    o pkg/autodiff:
457      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
458        criteria, return to simple (default) tape IO format.
459    o pkg/mdsio (+ eesupp/src):
460      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
461        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
462      - fix globalFile and singleCpuIO options using simpler global mapping.
463      - new pairs of scatter/gather vector S/R (one for each type, generated from
464        template) corresponding to simpler global mapping.
465      - adread_write.F: switch to new S/R (but leave old calls commented) and write
466        to globalFile when parameter globalFiles is set to True.
467      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
468    o pkg/autodiff:
469      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
470        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
471        missing, just add a STOP if array type do not match.
472    o pkg/exf:
473      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
474         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
475         and rename array obsSIce to exf_iceFraction.
476    o tutorial_deep_convection:
477      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
478        for now all in this exp. code dir.
479      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
480        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
481    o eesupp/src:
482      - added SINGLE_DISK_IO option because reading of parameter files on
483        very large number of processors did not work with existing set-up
484    
485    checkpoint64o (2013/09/25)
486    o pkg/atm_phys & atm_compon_interf:
487      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
488    o tools/build_options:
489      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
490        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
491        remove CPP setting (was identical to genmake2 default).
492    o pkg/gmredi & model/src: Some updating and work done on the residual model.
493      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
494      - fixed up the calculation of the eddy stress and how it is added to the
495        external forcing via taueddy_external_forcing.F
496      - at the moment, it is very experimental and only works with the variable eddy
497        diffusivity calculated in gmredi_k3d.F
498    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
499        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
500    o testreport (& tools/do_tst_2+2):
501      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
502    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
503      - remove CPP='cpp -traditional -P' (this is genmake2 default)
504      - add switch (for big setups) to use 'medium' memory-model (but leave it
505        commented out for now). Note: needed with FC 19 to compile big setups.
506    o pkg/atm_compon_interf:
507      - regroup per field origin (model & pkgs) the coupling storage routines
508         (which accumalate in time each coupling field)
509      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
510        update accordingly + simplify aim_do_physics.F
511    
512    checkpoint64n (2013/08/26)
513    o pkg/bbl:
514      - update formulation to reduce dispersion of tracer properties in bbl
515      - replaced horizontal and vertical transport parameters with velocities
516      - changes results for verification/global_with_exf.yearly
517    o verification/halfpipe_streamice:
518      - change to matrix construction; update both Fwd & AD output.
519    o verification/tutorial_tracer_adjsens:
520      - OpenAD test: switch to vector-invariant momentum since fluxform with
521        rStar causes problems with OpenAD; update output.
522    o tools:
523      - genmake2: define a common prefix for all temp-file names ; move them
524        to local /tmp disk (but would be easy to move them back);
525      - xmakedepend: apply the same switch for temp-files.
526    o pkg/offline:
527      - changes for use with rStar (NLFS): assume that we continue to provide
528        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
529        output files) and apply r* scaling at each time-step (function of the time
530        varying Eta field); use normal pickup files (needed for restart with NLFS).
531    o adjoint with OpenAD:
532      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
533        package openad.  This package has to be compiled for all runs with OpenAD
534        instead of specifying code_oad_all as a modification directory.
535      - link the fortran templates from tools/OAD_support to the build directory
536        for preprocessing to avoid conflicts between different setups compiled
537        simultaneously and simplify cleanup.
538    o pkg/exf:
539      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
540        main model or other pkgs are exchanged in EXF_MAPFIELDS).
541    o model/src:
542      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
543        (similar to do_fields_blocking_exchanges.F).
544    o tools/genmake2:
545      - remove TAF output src code just before calling staf (when not doing a fresh
546        built, will stop if things go wrong with staf).
547      - fix target "adobj" (left from TAF version-2 transition)
548    o pkg/diagnostics:
549      - add a parameter to track the status of pkg/diagnostics activation;
550        this replace/extend the use of logical param "settingDiags" (to check
551        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
552        New S/R to print error message and stop when pkgStatus is not right.
553      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
554    
555    checkpoint64m (2013/08/13)
556    o model/inc:
557      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
558        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
559    o pkg/kpp & aim_v23:
560      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
561    o pkg/seaice:
562      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
563        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
564      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
565    o eesupp/src:
566      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
567        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
568    o switch to TAF version-2:
569      - add flow directives to "freeze" naming convention for ad-routines that
570        are used in I/O routines of adjoint state and associated common blocks
571        that are used in adcommon.h (backward compatible with version-1)
572      - update all ad-optfiles (in tools/adjoint_options + few local to some
573        verification exp) to switch to latest TAF version (currently 2.5.5);
574        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
575        out except for diva).
576      - the major change with TAF version-2 is that both the differentiated
577        routines and the forward routines (new) are returned as part of the TAF
578        output source code. Update genmake2 accordingly.
579      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
580        with version-2 when compared to TLM or FWD gradient); other experiments
581        output show minor changes (machine truncation level); update the few AD &
582        TLM output with 12 matching digits only (some prior to version-2 switch).
583    
584    checkpoint64l (2013/08/05)
585    o model/src:
586      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
587      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
588        when using TAF but only if using OpenAD.
589    o pkg/mom_common+fluxform+vecinv:
590      - always set horiz. viscosity arrays to background value before calling
591        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
592        only when using variable horiz. viscosity (useVariableVisc=T);
593      - simplify mom_vecinv.F (only 1 block for momViscosity).
594    o pkg/mom_common: variable horiz. viscosity in NH code
595      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
596        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
597      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
598        useBiharmonicVisc & useVariableVisc.
599      - fix old bug (already in 1rst implementation of variable horizontal viscosity
600        in calc_gw.F, version 1.27, 2006/06/20):
601        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
602        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
603      - change background horiz viscosity in vertical momentum (gW) to always be
604        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
605        any type of variable viscosity, e.g., viscAh/4Grid)
606      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
607        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
608        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
609        default viscAh,viscA4 is zero).
610    o model/src:
611      - extend length of drC & recip_drC from Nr to Nr+1.
612    o Divided Adjoint (DIVA) with MPI:
613      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
614      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
615        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
616    
617    checkpoint64k (2013/07/23)
618    o tools/OAD_support:
619      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
620        and remove it from genmake2.
621    o tools/build_options:
622      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
623        MPI_HEADER_FILES list (let genmake2 find the missing headers)
624    o verification/halfpipe_streamice:
625      - change to driving stress formulation; update both Fwd & AD output.
626    o tools/genmake2 and Divided Adjoint with MPI:
627      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
628      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
629      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
630        Makefile, which is set by genmake2, and check which mpi-headers are needed.
631        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
632      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
633    o testreport:
634      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
635        perform additional runs (number of additional runs is "add_DIVA_runs" taken
636        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
637    o verification/lab_sea (AD test):
638      - change to test Divided Adjoint Run in this set-up (both standard AD test
639        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
640    o pkg atm_ & ocn_compon_interf:
641      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
642        staggerTimeStep implementation) and disable (retired) corresponding
643        parameter.
644    o pkg/offline:
645      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
646      - add S/R OFFLINE_CHECK to print offline parameter summary
647        and stop if loading a file that is not used;
648      - enable to calculate GMRedi tensor, KPP mixing and convective index
649        when the corresponding file(s) is/are not specified (but pkg is used).
650      - comment out resetting of monitorFreq (to endTime) since it still useful
651        for monitoring CFL numbers and checking offline fields.
652    o OpenAD:
653      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
654        smaller standard output) and generate new (smaller) output (on baudelaire
655        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
656    o model/src:
657      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
658        (where external_forcing_adjust was called) and change list of arguments;
659      - merge external_forcing_adjust.F into external_forcing_surf.F
660      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
661        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
662        previously in file "balance_relax.F", now removed); remove corresponding
663        arrays in FFIELDS.h.
664      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
665        a hack for getting back surfaceForcingS (loaded from file) when using
666        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
667      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
668        (was getting only 11 digits for AD-grad, due to different truncation
669         error in AD code).
670    
671    checkpoint64j (2013/07/04)
672    o pkg/offline:
673      - to enable the use of other features with pkg offline (e.g., obcs),
674        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
675      - comment out "allowFreezing" (now active) in 2 offline testing exp.
676    o pkg/exf ALLOW_RUNOFTEMP
677      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
678      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
679      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
680    o pkg/atm_phys:
681      - allows to add some damping on uVel,vVel (strength only function of k).
682    o verification, ad-tests:
683      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
684        global_ocean_ebm and offline_exf_seaice.thsice.
685    o verification/halfpipe_streamice:
686      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
687        flux input boundary conditions to be ignored; a fix for this bug changed
688        verification results for forward test.
689      - add adjoint test.
690    o pkg/ptracers:
691      - allow to restart without SOM pickup (resetting SOM to zero).
692    o pkg/gmredi:
693      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
694      - It uses mixing length theory and suppression by steering level effects to
695        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
696        to JPO, for more details).
697      - It also uses the diffusivity to calculate an eddy induced streamfunction
698        based on a PV closure (rather than a buoyancy closure as in GM).
699      - New files added to pkg/gmredi:
700        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
701          induced overturning streamfunction (called from gmredi_calc_tensor)
702        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
703          for use in gmredi_k3d
704        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
705          the eddy diffusivity
706    
707    checkpoint64i (2013/06/18)
708    o pkg/cheapaml:
709      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
710        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
711        with pkg/cheapaml.
712    o utils/python: add subpackage for cubed sphere function, first example is
713        simple cs.pcol to plot 2D fields on a map
714    o pkg/streamice:
715      - This is a new package in MITgcm, which solves dynamic equations for ice
716         sheets and ice streams
717      - At the moment it is independent of atmosphere/ocean dynamics, or any
718        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
719        ed that this will change)
720      - There is a new verification exercise that tests it, halfpipe_streamice,
721        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
722        rectangular embayment
723      - halfpipe_streamice is forward-only for now, will have TAF test soon
724      - for questions, email dgoldber@mit.edu
725    o pkg/thsice:
726      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
727        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
728      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
729         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
730      - allow precip from pkg/cheapaml to make snow over seaice.
731    o pkg/cfc:
732      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
733      - remove atmos CFC 2-D arrays from common bloc (now local variables)
734      - change some hard-coded constant to run time parameter for reading and
735        and interpolating atmospheric CFC ; keep same default as previously.
736      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
737      - put arguments in standard order: myTime, myIter, myThid
738      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
739        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
740      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
741      - new routine to print summary of CFC params and check for consistency.
742    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
743      similar to thsice_advdiff.
744      Note that for the B-grid case the routine parameters uc/vc are overwritten.
745    o pkg/cfc:
746      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
747        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
748      - fix interpolation of atmphspheric CFC between Sorthern and Northern
749        hemisphere value.
750    o pkg/seaice:
751      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
752    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
753                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
754      - requires an additional time level that is stored in the pickup
755      - you can start with AB2 from a pickup without this time level with
756        pickupStrictlyMatch = .false.
757    
758    checkpoint64h (2013/05/26)
759    o pkg/cheapaml:
760      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
761        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
762      - consistent treatment of uWind,vWind location: assume everywhere in
763        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
764        (Note: was already the case for Tair,Qair advection);
765        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
766      - compute diabatic forcing only in the interior (excluding overlap regions)
767      - fill in array "Qsw" (for short-wave heating);
768      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
769        before any update (consistent with MITgcm state var diagnostics);
770      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
771        non periodic ; + adjusted for uWind,vWind (C-grid).
772    o pkg/seaice:
773      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
774        add explicitly pkg/exf in experiments that currently use pkg/seaice.
775      - allows to compile pkg/seaice without pkg/exf.
776    o tools/OAD_support:
777      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
778        of array "ourStepOf" in function rvNextAction (revolve.F90).
779    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
780      - change pkg name (to be used with other atmospheric physics pkg)
781        but by-pass CVS when making the new pkg so that we keep the CVS history.
782    o pkg/offline:
783      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
784        (previously called from pkg/dic_surfforcing_init.F)
785    o model/src:
786      - re-order sequence of calls within packages_init_variables.F, using
787        standard order, except for:
788         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
789         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
790    o new pkg: atm_phys
791      - add entry point and source code (previously in contrib
792          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
793        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
794      - re-order sequence of calls within packages_readparms.F,
795         packages_init_fixed.F and packages_write_pickup.F
796        (but skip packages_init_variables.F because of TAF issues).
797      - update contrib/*/atm_gray/ experiment.
798    o pkg/seaice (ITD code):
799      - simplify and fix the writing of pickup-files for ITD case
800    o pkg/seaice (ITD code):
801      - introduce floe size dependent lateral melt for ITD case;
802      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
803      - update seaice_itd experiment main output.
804    o pkg/thsice:
805      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
806        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
807        changed accordingly pkg/atm2d.
808    
809    checkpoint64g (2013/05/01)
810    o pkg/exf ALLOW_RUNOFTEMP
811      - if defined,  river and glacier runoff temperature can be read-in from
812        runoftempfile; runoftempfile needs to have same format as runofffile
813    o pkg/thsice (& pkg/bulk_force):
814      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
815        for energy content of Precip + RunOff & Evap (like with pkg/exf).
816      - change computation domain to always be the interior (without overlap).
817      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
818    o verification/tutorial_global_oce_biogeo:
819      - add preliminary OpenAD setup (still has problems)
820    o pkg/seaice:
821      - turn some parameters for choosing the convergence criterion of
822        the inexact Newton method (JFNK) into runtime parameters for convenience
823      - clean up seaice_calc_viscosities.F: remove/retire two options for
824        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
825        the results of lab_sea/input because a division has been replaced by
826        a multiplication with the reciprocal (sumNorm)
827      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
828        convergence of solver (changes results, of course), and to test some
829        new features
830    o model/src:
831      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
832      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
833      - move forcing adjustment (balancing surface forcing) in specific S/R
834        where might also be applied exchanges (if needed) to forcing arrays.
835    o pkg/shelfice:
836      - allow to specify the Ice-Shelf mass per unit area (instead of
837        shelficeLoadAnomaly) and do the conversion from one to the other
838      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
839        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
840        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
841        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
842      - update isomip experiment forward output (get machine truncation error
843        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
844    o verification/offline_exf_seaice:
845      revise data.seaice in input.thermo and input_ad and update results accordingly
846        HO = 0.2, SEAICE_areaLossFormula = 2,
847        SEAICE_growMeltByConv = .TRUE.,
848        SEAICE_doOpenWaterMelt = .TRUE.,
849      Improve consistency with input.thsice and fix the spurious 500m ice corners
850    o verification/global_ocean.cs32x15:
851      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
852        in icedyn (thsice+seaice-dyn) test and update output.
853    o verification/offline_exf_seaice:
854      - adjust list of tested variables (with testreport) and update
855        standard test output with better slection of monitored fields.
856    o pkg/cd_code:
857      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
858        experiment lab_sea.hb87
859    o tools/genmake2:
860      - change default makedepend from the system default to tools/xmakedepend:
861        When no makedepend is specified, select tools/xmakedepend it the test pass,
862        otherwise select the system default (if exist and pass the test) or
863        try to build cyrus-makedepend ; stop if none of the 3 works.
864    o pkg/exf & pkg/thsice:
865      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
866        for energy content of Precip + RunOff & Evap. Assumes:
867       1) Rain has same temp as Air.
868       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
869       3) Run-Off comes at the temp of surface water (with same Cp)
870       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
871        put directly into Latent Heat flux & should use water-vapor heat capacity.
872       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
873        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
874    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
875        (compile when SEAICE_ALLOW_JFNK is defined)
876    o pkg/thsice:
877      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
878        implementation): move THSICE_AVE call after the advection (called directly
879        from thsice_do_advect.F).
880    o verification/global_ocean.90x40x15 and OpenAD:
881      New experiment for OpenAD is identical to the one in input_ad except that
882        multiDimAdvection=.FALSE.,
883      There is still an issue with this.
884    o pkg/thsice:
885      - account for ice velocity (ocean relative velocity) in turbulent heat flux
886        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
887        and offline_exf_seaice (main test).
888    
889    checkpoint64f (2013/03/31)
890    o verification/OpenAD:
891      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
892    o verification/isomip, pkg/shelfice and OpenAD:
893      - add OpenAD setup to this exp and make shelfice package work with OpenAD
894    o verification/tutorial_global_oce_biogeo:
895      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
896    o verification/offline_exf_seaice:
897      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
898    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
899      - add OpenAD setup to this exp and make ptracers package work with OpenAD
900    o pkg/seaice/seaice_evp.F:
901       mask the asymmetric contribution of the ice-ocean stress (when
902       the turningAngle is non-zero) over open water to avoid stripes
903       in the EVP-solutions after many EVP-substeps. This does not change
904       the verification experiment (because turningAngle=0 in that experiment),
905       but will affect other EVP solutions with turningAngle.ne.0
906    o verification, AD & TLM output:
907      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
908        additions and multiplications which affect results at machine truncation
909        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
910        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
911        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
912        digits of matching.
913    o pkg/seaice:
914       modify lsr-algorithm so that it vectorizes AND converges by using a
915       "zebra" method: split vector loop into two with step size 2; this
916       solves a general convergence problem for the JFNK solver on a vector
917       computer. It has the potential to even improve convergence for
918       non-vector machines, but it does change the results so it is turned
919       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
920       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
921    
922    checkpoint64e (2013/03/05)
923    o pkg/ecco and several verification experiments:
924       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
925       from ecco package, and revert to unified routine in model/src/
926       Adjust verification experiments accordingly, especially gloal_oce_llc90
927       Should conclude long-standing work by Gael to reconsile the_main_loop with
928       ECCO and will enable OpenAD's revolve loop in ECCO setup.
929    o pkg/generic_advdiff:
930      - implement compressible flow method for multi-dim advection (similar to
931        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
932        TAF generates many recomputations) to use it; no yet coded with implicit
933        vertical advection.
934      - change experiment advect_cs (new output) and advect_xy (same output)
935        to test compressible flow multi-dim advection.
936    o pkg/generic_advdiff:
937      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
938        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
939    o pkg/seaice:
940      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
941        bug affects two verification experiments (lab_sea and lab_sea.hb87),
942        recover old (wrong) results by setting noSlipFac = 2. in
943        seaice_calc_strainrates.F;
944      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
945      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
946        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
947      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
948    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
949      - new subroutines seaice_lsr_tridiagu/v
950      - introduce loop bounds i/jmin/max to be able to use a restricted
951        additive Schwarz method, but not used for now.
952      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
953      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
954    o OpenAD support
955       Reorganize S/R call for overall time-stepping loop to facilitate
956       OpenAD revolve loop replacement
957       (new S/R main_do_loop.F)
958    o model/src:
959      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
960      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
961        ADAMS_BASHFORTH2.
962    o pkg/cheapaml:
963      - add new parameter (default=F, same as before) to disable full domain
964        (including land) periodicity in X & Y dir.
965      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
966        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
967        into single S/R CHEAPAML_TIMESTEP.
968    
969    checkpoint64d (2013/02/17)
970  o pkg/monitor (angular momentum):  o pkg/monitor (angular momentum):
971    - do not add Eta contribution to the total AM if using rigid-lid;    - do not add Eta contribution to the total AM if using rigid-lid;
972    - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).    - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
