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