4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o verification/lab_sea:
8      update adjoint and TLM output following changes to pkg/salt_plume
9    o pkg/salt_plume: modifications by An Nguyen:
10      - add capability to do brine rejection (salt-plume) as function of
11        volume+tracers (instead of only salinity tracer).
12      - conserve volume by exchanging volume from each kLev to above to
13        accommodate in-coming brine volume
14      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
15      - switch KPP surf buoyancy due to brine forcing to 3-d
16        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
17      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
18      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
19        in East/West Arctic.
20    o pkg/sbo:
21      - incorporate modifications from Katherine Quinn to enable the use of sbo
22        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
23        output for future testreport verification (unfinished).
24    o pkg/atm_phys:
25      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
26        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
27        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
28    o pkg/seaice
29      seaice_calc_ice_strength.F: modify expression to avoid divisions
30        (affects truncation)
31      seaice_do_ridging.F: clean up the insectarium
32      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
33      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
34      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
35      - add some debugging information and error messages (warnings)
36    o model/src: modifications relatd to atmosphere p*:
37      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
38      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
39        of vertical profile tRef in geopotential background and anomaly.
40      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
41        and pkg/atm_phys.
42      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
43        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
44    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
45    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
46        not used right now, but can be used in BGC packages to fix conservation.
47    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
48        other packages too.
49    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
50        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
51    o model/src:
52      - since we have several heat capacity (even in model/src), define "recip_Cp"
53        as local variable (no longer in common block) to avoid any confusion.
54      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
55    o pkg/exf:
56      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
57        air density as function of air Temp, Humidity and atm pressure.
58    
59    checkpoint64w (2014/05/02)
60    o verification:
61      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
62        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
63        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
64        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
65        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
66    o model/src: for atmosphere in p* coords:
67      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
68      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
69        but not yet activated.
70    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
71      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
72      - this changes the results (but not for any verification experiment, because
73        none tests this), but avoids having an extra field in the restart files
74    o pkg/seaice: remove global variable TICE (not needed)
75      - replace by TICES or local variable where necessary (cost_seaice_test,
76        seaice_diagnostics_state)
77      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
78      - use specific read/write routines for reading and writing individual leves
79        of a multilevel field
80    o pkg/ctrl & model/inc:
81      - move additional anomaly fields of control vars (related to options:
82         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
83        from DYNVARS.h into new header file: CTRL_FIELDS.h
84    o pkg/seaice: some small modifications to the ridging code
85      - make fw2ObyRidge a global variable and add the freshwater flux to
86        seaice_growth
87      - pass actual thickness from seaice_prepare_ridging, so that it is
88        computed only in one place and compute it in the same way as in
89        seaice_growth
90      - initialise more fields in seaice_do_ridging that where cause floating
91        point exceptions over land
92    o pkg/seaice: preparations for ridging code and first real ridging code
93      - move most of "PART 1" of S/R seaice_growth into a new and separate
94        S/R seaice_reg_ridge that will both regularize the state variable after
95        advection call the actual ridging routine;
96      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
97        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
98      - remove ridging code from seaice_advdiff
99      - clean up remaining part 1 of seaice_growth in an attempt to make it
100        more readable (this is probably subjective)
101      - call seaice_itd_redist once in the initialisation phase to have the initial
102        conditions in the correct category
103      - finally: add new ridging routine for ITD code
104    
105    checkpoint64v (2014/04/11)
106    o pkg/ecco:
107      - add runtime parameters mdt[start,end]date[1,2]
108      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
109    o pkg/seaice:
110      - make deltaC a global variable, so that it can be used in ridging code
111      - first step towards ridging: introduce new routines that compute
112        ice strength based on ridging parameters
113      - add diagnostic for HSNOWITD
114      - add opnWtrFrac as a global variable (required for ridging scheme)
115    o pkg/salt_plume + pkg/seaice/seaice_growth.F
116      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
117        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
118    o verification/hs94.1x64x5:
119      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
120      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
121    o autodiff:
122      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
123        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
124        For now, only in pkgs used in verification/hs94.1x64x5.
125      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
126        which are specific to TAF/TAMC).
127      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
128        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
129        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
130      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
131        building mitgcmuv_ad (make adAll).
132    o pkg/ecco:
133      - cost_gencost_seaicev4.F:
134         reformulate proxy cost as function of sst and local param SEAICE_freeze
135         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
136      - add stop statement if old names siv4-[sst,vol] are used
137      - add snapshots + cost reports for atmospheric longwave
138      - remove factor 0.1 in front of wtau[u,v]
139      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
140         ALLOW_TMI_SST_COST_CONTRIBUTION
141    o pkg/atm_phys:
142      - add some diagnostics for Short-wave and for convection S/R.
143    o pkg/seaice/seaice_growth:
144      - fix a bug in the lateral melt parameterization for SEAICE_ITD
145        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
146      - rearrange loop order for better vector code in the same code block
147      - rewrite the floeDiameter formula to have fewer divisions
148      -  (miraculously) none of this changes the results of seaice_itd
149    o pkg/smooth:
150      - move param smooth2Ddiffnbt to pkg/ecco
151    o pkg/salt_plume:
152      - salt_plume_frac.F:
153         clean up local param names
154         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
155    o pkg/rw:
156      - add RS version of S/R READ_MFLDS_LEV.
157    o pkg/streamice:
158      - fix the restart test by writing/reading pickup_streamice files.
159    o pkg/seaice:
160      - refine checks for jfnk-related parameters
161      - comment out if statement with SEAICEuseIMEX parameter as long as there
162        is no IMEX code to avoid confusion and surprises
163    
164    checkpoint64u (2014/03/07)
165    o verification/MLAdjust:
166      - rename secondary test suffix:
167         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
168         0.leithD -> AhFlxF  + switch to flux-form
169         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
170         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
171    o pkg/mom_vecinv:
172      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
173        to be before mom_calc_visc.F)
174      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
175      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
176        this is simpler for the adjoint and for diagnostics.
177    o model/src + pkg/momentum:
178      - add input files for  2-D additional Western and Southern cell-edge wall
179         (e.g., to add "thin-wall" where it is =1).
180      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
181        using 2nd hFacZ that is computed from initial (fix domain) hFac
182      - known limitations of thin wall implementation: not yet coded for sigma
183        coords; not working with CD-scheme neither.
184    o pkg/seaice:
185      - rename recently introduced parameters from (wrong name) AB to
186        BDF (backward difference time discretisation)
187      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
188    o tools/adjoint_options:
189      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
190    
191    checkpoint64t (2014/02/01)
192    o pkg/ecco
193      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
194        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
195      - replace hard-coded record number and period which only work for monthly
196        with read-in runtime param that works for other periods (month,day,year)
197    o pkg/thsice
198      - corrected store directive fixes thsice adjoint gradient checks
199    o genmake2 & testreport:
200      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
201        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
202        Update testreport accordingly. No need to set "export OPENAD=true"
203        in adjoint_options/adjoint_oad anymore (will be removed later).
204    o pkg/shelfice:
205      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
206        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
207        so that surface forcing applies to k=kSurf if using pkg/shelfice.
208    o pkg/ctrl, pkg/grdchk, pkg/ecco:
209      - Changes to make GENARR more modular (i.e. invisible if not used)
210    o model/src/temp_integrate.F and salt_integrate.F
211      - re-include store directives that were removed on Dec 27th.
212    o model/src/external_forcing_surf.F
213      - add storage directives for EmPmR and PmEpR to avoid recomputation of
214        seaice_model in the adjoint that is problematic when seaice_model is
215        turned off in the adjoint. The resolved issue dated back to July when
216        EXTERNAL_FORCING_SURF call was moved.
217        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
218    o pkg/exf/exf_check.F
219      - fix a small bug again (originally found by Wentao Liu, now found again)
220      - streamline error output
221    o pkg/streamice and aim_v23:
222      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
223        Apple's /usr/bin/cpp knows what to do:
224        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
225        Target: x86_64-apple-darwin13.0.0
226    
227    checkpoint64s (2014/01/05)
228    o tools/adjoint_options:
229      - switch to fastopt.net TAF server (instead of default fastopt.de) for
230        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
231    o model/src:
232      - remove some unnecessary TAF storage directives in forward_step.F and
233        in dynamics.F (note: not always removed by TAF, e.g., double storage
234        of kappaRU,kappaRV in former version of dynamics.F).
235    o model/src & pkg/ptracers:
236      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
237        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
238        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
239      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
240      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
241      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
242    o useSingleCpuInput separates single-CPU input from single-CPU output;
243        for now only implemented for in exf_interp_read.F
244    o verification/advect_xy:
245      - fix missing EXCH call in local version of ini_salt.F and update output.
246    o momentum diagnostics:
247      - fix which deltaT is used in Total-Tendency diagnostics.
248      - fix typo in diagnostics for momentum tendency from AB.
249    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
250        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
251    
252    checkpoint64r (2013/12/08)
253    o verification/*/results:
254      - Update reference output of experiments that were passing with just 13 digits
255         (make it easier to detect future changes in results)
256    o model/src & pkg/ptracers:
257      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
258        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
259        to inside ptracers_integrate.F ; remove ptracers_advection.F
260    o coupling interface pkgs:
261        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
262      - change the config check to test the agreement of Ocean Depth
263        with ATM land/sea mask (instead of ATM orography);
264      - send to coupler the number of coupler time-steps to do for this run:
265        this allows to check for consistency and don't need anymore to be
266        specified in parameter file "data";
267      in coupler:
268      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
269      - improve report to log-file of config setting (pass log-file unit to few S/R)
270    o pkg/compon_communic:
271      - add coupling send/receive for non-tiled integer vector;
272      - add S/R to check and stop if any proc has an error (similar to
273        eesupp/src/stop_if_error.F but single thread and across Comm_World).
274    o pkg/exch2:
275      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
276        through list of all tiles my proc owns.
277    o model/src:
278      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
279        from rTrans) to simplify dependencies (no need to store rTrans anymore in
280        calling S/R); this affects AD results at machine truncation level:
281        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
282        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
283    o tools/build_options:
284      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
285    o coupling interface pkgs:
286        [compon_communic, atm_compon_interf & ocn_compon_interf]
287      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
288        to each S/R that needs it; remove un-used variables.
289      - change component tile registration (cpl_register.F in both compon_interf
290        and mitcomponent_tile_register.F) to pass the full list of tiles
291        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
292      - with pkg/exch2: adopt the same convention used for I/O to define mapping
293        towards coupler global array (unless W2_useE2ioLayOut=F):
294         a) can now use different tiling between atm & ocn comp.
295         b) no needs to modify the run-Off map when changing tiling (was needed
296            even if using the same tiling between atm & ocn).
297         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
298            full land tiles); not yet tested.
299      - check for valid mapping from comp. tile to coupler global array
300      - improve report of tile registration results to log file.
301    o pkg/exch2:
302      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
303        tile-registration (CPL_REGISTER);
304      - activate (un-comment) definition and setting of "W2_tileIndex" list to
305        store the local bi,bj indices of each tile;
306      - also print bi,bj in local report to log file;
307      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
308        Jun 2009 modif of pkg/exch2).
309    o testing on baudelaire:
310      - run 2 tests at a time: no significant slow down (since enough cpu) and
311        get the full set of test done earlier
312      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
313    o model/src/thermodynamics.F and routines called from it:
314      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
315        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
316        velocity (outp) by adding bolus velocity.
317      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
318        mass transport from velocity + lateral grid cell area
319      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
320      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
321     in thermodynamics.F
322      - remove k from thermodynamics.F and move it to temp_integrate.F
323        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
324        loop).
325      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
326        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
327        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
328        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
329      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
330        global_ocean.90x40x15, tutorial_global_oce_biogeo and
331        tutorial_tracer_adjsens (+ TLM output).
332    o tools/OAD_support and (verification/*/) code_oad:
333      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
334        module conversion ; remove unneeded CPP_EEOPTIONS.h.
335      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
336        version (closer to model/inc/CPP_OPTIONS.h).
337    o model/src:
338      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
339        retired list of parameters (routine FREEZE has been replace by surface
340        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
341    o pkg/gmredi:
342      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
343        velocity (same scheme but affects machine truncation) for GM_AdvForm.
344      - update output of FWD experiments: front_relax.bvp,
345        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
346    
347    checkpoint64q (2013/11/17)
348    o verification:
349      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
350        tutorial_global_oce_biogeo and global_ocean.90x40x15.
351      - generate new output (growth & melt) for seaice_itd experiment after
352        updating the input pickup_seaice files (previously wrong).
353    o pkg/cost:
354      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
355        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
356        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
357          cannot be applied to var in common block).
358        o allows to get results independent of tile-per-proc setting (if using
359          slower GLOBAL_SUM_SEND_RECV option).
360      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
361        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
362        forward gradients: update output).
363      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
364        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
365    o pkg/mom_common:
366      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
367        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
368        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
369        ensure that all field value that are used are set.
370    o tutorial_deep_convection (smag3d):
371      - add missing scaling in mom_calc_smag_3d.F;
372      - set smag3D_coeff in input.smag3d such that results do not change.
373    o pkg/dic:
374      - change dic_cost.F to compute cost on each tile first and then apply
375        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
376        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
377      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
378    o eesupp/src & pkg/mdsio:
379      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
380        (from pkg/mdsio) since they are no longer used for tape IO.
381      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
382        (+ keep a copy in pkg/atm_ocn_coupler).
383    o verification/isomip:
384      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
385    o tools/build_options:
386      - optfile linux_amd64_ifort11, fast (no ieee) case:
387        to get a working restart for all experiments, add "-fp-model source"
388        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
389    
390    checkpoint64p (2013/10/20)
391    o pkg/autodiff:
392      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
393        criteria, return to simple (default) tape IO format.
394    o pkg/mdsio (+ eesupp/src):
395      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
396        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
397      - fix globalFile and singleCpuIO options using simpler global mapping.
398      - new pairs of scatter/gather vector S/R (one for each type, generated from
399        template) corresponding to simpler global mapping.
400      - adread_write.F: switch to new S/R (but leave old calls commented) and write
401        to globalFile when parameter globalFiles is set to True.
402      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
403    o pkg/autodiff:
404      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
405        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
406        missing, just add a STOP if array type do not match.
407    o pkg/exf:
408      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
409         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
410         and rename array obsSIce to exf_iceFraction.
411    o tutorial_deep_convection:
412      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
413        for now all in this exp. code dir.
414      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
415        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
416    o eesupp/src:
417      - added SINGLE_DISK_IO option because reading of parameter files on
418        very large number of processors did not work with existing set-up
419    
420    checkpoint64o (2013/09/25)
421    o pkg/atm_phys & atm_compon_interf:
422      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
423    o tools/build_options:
424      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
425        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
426        remove CPP setting (was identical to genmake2 default).
427    o pkg/gmredi & model/src: Some updating and work done on the residual model.
428      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
429      - fixed up the calculation of the eddy stress and how it is added to the
430        external forcing via taueddy_external_forcing.F
431      - at the moment, it is very experimental and only works with the variable eddy
432        diffusivity calculated in gmredi_k3d.F
433    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
434        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
435    o testreport (& tools/do_tst_2+2):
436      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
437    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
438      - remove CPP='cpp -traditional -P' (this is genmake2 default)
439      - add switch (for big setups) to use 'medium' memory-model (but leave it
440        commented out for now). Note: needed with FC 19 to compile big setups.
441    o pkg/atm_compon_interf:
442      - regroup per field origin (model & pkgs) the coupling storage routines
443         (which accumalate in time each coupling field)
444      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
445        update accordingly + simplify aim_do_physics.F
446    
447    checkpoint64n (2013/08/26)
448    o pkg/bbl:
449      - update formulation to reduce dispersion of tracer properties in bbl
450      - replaced horizontal and vertical transport parameters with velocities
451      - changes results for verification/global_with_exf.yearly
452    o verification/halfpipe_streamice:
453      - change to matrix construction; update both Fwd & AD output.
454    o verification/tutorial_tracer_adjsens:
455      - OpenAD test: switch to vector-invariant momentum since fluxform with
456        rStar causes problems with OpenAD; update output.
457    o tools:
458      - genmake2: define a common prefix for all temp-file names ; move them
459        to local /tmp disk (but would be easy to move them back);
460      - xmakedepend: apply the same switch for temp-files.
461    o pkg/offline:
462      - changes for use with rStar (NLFS): assume that we continue to provide
463        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
464        output files) and apply r* scaling at each time-step (function of the time
465        varying Eta field); use normal pickup files (needed for restart with NLFS).
466    o adjoint with OpenAD:
467      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
468        package openad.  This package has to be compiled for all runs with OpenAD
469        instead of specifying code_oad_all as a modification directory.
470      - link the fortran templates from tools/OAD_support to the build directory
471        for preprocessing to avoid conflicts between different setups compiled
472        simultaneously and simplify cleanup.
473    o pkg/exf:
474      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
475        main model or other pkgs are exchanged in EXF_MAPFIELDS).
476    o model/src:
477      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
478        (similar to do_fields_blocking_exchanges.F).
479    o tools/genmake2:
480      - remove TAF output src code just before calling staf (when not doing a fresh
481        built, will stop if things go wrong with staf).
482      - fix target "adobj" (left from TAF version-2 transition)
483    o pkg/diagnostics:
484      - add a parameter to track the status of pkg/diagnostics activation;
485        this replace/extend the use of logical param "settingDiags" (to check
486        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
487        New S/R to print error message and stop when pkgStatus is not right.
488      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
489    
490    checkpoint64m (2013/08/13)
491    o model/inc:
492      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
493        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
494    o pkg/kpp & aim_v23:
495      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
496    o pkg/seaice:
497      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
498        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
499      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
500    o eesupp/src:
501      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
502        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
503    o switch to TAF version-2:
504      - add flow directives to "freeze" naming convention for ad-routines that
505        are used in I/O routines of adjoint state and associated common blocks
506        that are used in adcommon.h (backward compatible with version-1)
507      - update all ad-optfiles (in tools/adjoint_options + few local to some
508        verification exp) to switch to latest TAF version (currently 2.5.5);
509        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
510        out except for diva).
511      - the major change with TAF version-2 is that both the differentiated
512        routines and the forward routines (new) are returned as part of the TAF
513        output source code. Update genmake2 accordingly.
514      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
515        with version-2 when compared to TLM or FWD gradient); other experiments
516        output show minor changes (machine truncation level); update the few AD &
517        TLM output with 12 matching digits only (some prior to version-2 switch).
518    
519    checkpoint64l (2013/08/05)
520    o model/src:
521      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
522      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
523        when using TAF but only if using OpenAD.
524    o pkg/mom_common+fluxform+vecinv:
525      - always set horiz. viscosity arrays to background value before calling
526        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
527        only when using variable horiz. viscosity (useVariableVisc=T);
528      - simplify mom_vecinv.F (only 1 block for momViscosity).
529    o pkg/mom_common: variable horiz. viscosity in NH code
530      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
531        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
532      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
533        useBiharmonicVisc & useVariableVisc.
534      - fix old bug (already in 1rst implementation of variable horizontal viscosity
535        in calc_gw.F, version 1.27, 2006/06/20):
536        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
537        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
538      - change background horiz viscosity in vertical momentum (gW) to always be
539        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
540        any type of variable viscosity, e.g., viscAh/4Grid)
541      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
542        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
543        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
544        default viscAh,viscA4 is zero).
545    o model/src:
546      - extend length of drC & recip_drC from Nr to Nr+1.
547    o Divided Adjoint (DIVA) with MPI:
548      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
549      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
550        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
551    
552    checkpoint64k (2013/07/23)
553    o tools/OAD_support:
554      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
555        and remove it from genmake2.
556    o tools/build_options:
557      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
558        MPI_HEADER_FILES list (let genmake2 find the missing headers)
559    o verification/halfpipe_streamice:
560      - change to driving stress formulation; update both Fwd & AD output.
561    o tools/genmake2 and Divided Adjoint with MPI:
562      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
563      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
564      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
565        Makefile, which is set by genmake2, and check which mpi-headers are needed.
566        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
567      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
568    o testreport:
569      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
570        perform additional runs (number of additional runs is "add_DIVA_runs" taken
571        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
572    o verification/lab_sea (AD test):
573      - change to test Divided Adjoint Run in this set-up (both standard AD test
574        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
575    o pkg atm_ & ocn_compon_interf:
576      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
577        staggerTimeStep implementation) and disable (retired) corresponding
578        parameter.
579    o pkg/offline:
580      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
581      - add S/R OFFLINE_CHECK to print offline parameter summary
582        and stop if loading a file that is not used;
583      - enable to calculate GMRedi tensor, KPP mixing and convective index
584        when the corresponding file(s) is/are not specified (but pkg is used).
585      - comment out resetting of monitorFreq (to endTime) since it still useful
586        for monitoring CFL numbers and checking offline fields.
587    o OpenAD:
588      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
589        smaller standard output) and generate new (smaller) output (on baudelaire
590        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
591    o model/src:
592      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
593        (where external_forcing_adjust was called) and change list of arguments;
594      - merge external_forcing_adjust.F into external_forcing_surf.F
595      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
596        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
597        previously in file "balance_relax.F", now removed); remove corresponding
598        arrays in FFIELDS.h.
599      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
600        a hack for getting back surfaceForcingS (loaded from file) when using
601        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
602      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
603        (was getting only 11 digits for AD-grad, due to different truncation
604         error in AD code).
605    
606    checkpoint64j (2013/07/04)
607    o pkg/offline:
608      - to enable the use of other features with pkg offline (e.g., obcs),
609        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
610      - comment out "allowFreezing" (now active) in 2 offline testing exp.
611    o pkg/exf ALLOW_RUNOFTEMP
612      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
613      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
614      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
615    o pkg/atm_phys:
616      - allows to add some damping on uVel,vVel (strength only function of k).
617    o verification, ad-tests:
618      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
619        global_ocean_ebm and offline_exf_seaice.thsice.
620    o verification/halfpipe_streamice:
621      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
622        flux input boundary conditions to be ignored; a fix for this bug changed
623        verification results for forward test.
624      - add adjoint test.
625    o pkg/ptracers:
626      - allow to restart without SOM pickup (resetting SOM to zero).
627    o pkg/gmredi:
628      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
629      - It uses mixing length theory and suppression by steering level effects to
630        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
631        to JPO, for more details).
632      - It also uses the diffusivity to calculate an eddy induced streamfunction
633        based on a PV closure (rather than a buoyancy closure as in GM).
634      - New files added to pkg/gmredi:
635        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
636          induced overturning streamfunction (called from gmredi_calc_tensor)
637        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
638          for use in gmredi_k3d
639        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
640          the eddy diffusivity
641    
642    checkpoint64i (2013/06/18)
643    o pkg/cheapaml:
644      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
645        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
646        with pkg/cheapaml.
647    o utils/python: add subpackage for cubed sphere function, first example is
648        simple cs.pcol to plot 2D fields on a map
649    o pkg/streamice:
650      - This is a new package in MITgcm, which solves dynamic equations for ice
651         sheets and ice streams
652      - At the moment it is independent of atmosphere/ocean dynamics, or any
653        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
654        ed that this will change)
655      - There is a new verification exercise that tests it, halfpipe_streamice,
656        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
657        rectangular embayment
658      - halfpipe_streamice is forward-only for now, will have TAF test soon
659      - for questions, email dgoldber@mit.edu
660    o pkg/thsice:
661      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
662        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
663      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
664         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
665      - allow precip from pkg/cheapaml to make snow over seaice.
666    o pkg/cfc:
667      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
668      - remove atmos CFC 2-D arrays from common bloc (now local variables)
669      - change some hard-coded constant to run time parameter for reading and
670        and interpolating atmospheric CFC ; keep same default as previously.
671      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
672      - put arguments in standard order: myTime, myIter, myThid
673      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
674        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
675      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
676      - new routine to print summary of CFC params and check for consistency.
677    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
678      similar to thsice_advdiff.
679      Note that for the B-grid case the routine parameters uc/vc are overwritten.
680    o pkg/cfc:
681      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
682        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
683      - fix interpolation of atmphspheric CFC between Sorthern and Northern
684        hemisphere value.
685    o pkg/seaice:
686      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
687    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
688                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
689      - requires an additional time level that is stored in the pickup
690      - you can start with AB2 from a pickup without this time level with
691        pickupStrictlyMatch = .false.
692    
693    checkpoint64h (2013/05/26)
694    o pkg/cheapaml:
695      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
696        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
697      - consistent treatment of uWind,vWind location: assume everywhere in
698        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
699        (Note: was already the case for Tair,Qair advection);
700        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
701      - compute diabatic forcing only in the interior (excluding overlap regions)
702      - fill in array "Qsw" (for short-wave heating);
703      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
704        before any update (consistent with MITgcm state var diagnostics);
705      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
706        non periodic ; + adjusted for uWind,vWind (C-grid).
707    o pkg/seaice:
708      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
709        add explicitly pkg/exf in experiments that currently use pkg/seaice.
710      - allows to compile pkg/seaice without pkg/exf.
711    o tools/OAD_support:
712      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
713        of array "ourStepOf" in function rvNextAction (revolve.F90).
714    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
715      - change pkg name (to be used with other atmospheric physics pkg)
716        but by-pass CVS when making the new pkg so that we keep the CVS history.
717    o pkg/offline:
718      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
719        (previously called from pkg/dic_surfforcing_init.F)
720    o model/src:
721      - re-order sequence of calls within packages_init_variables.F, using
722        standard order, except for:
723         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
724         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
725    o new pkg: atm_phys
726      - add entry point and source code (previously in contrib
727          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
728        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
729      - re-order sequence of calls within packages_readparms.F,
730         packages_init_fixed.F and packages_write_pickup.F
731        (but skip packages_init_variables.F because of TAF issues).
732      - update contrib/*/atm_gray/ experiment.
733    o pkg/seaice (ITD code):
734      - simplify and fix the writing of pickup-files for ITD case
735    o pkg/seaice (ITD code):
736      - introduce floe size dependent lateral melt for ITD case;
737      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
738      - update seaice_itd experiment main output.
739    o pkg/thsice:
740      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
741        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
742        changed accordingly pkg/atm2d.
743    
744    checkpoint64g (2013/05/01)
745    o pkg/exf ALLOW_RUNOFTEMP
746      - if defined,  river and glacier runoff temperature can be read-in from
747        runoftempfile; runoftempfile needs to have same format as runofffile
748    o pkg/thsice (& pkg/bulk_force):
749      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
750        for energy content of Precip + RunOff & Evap (like with pkg/exf).
751      - change computation domain to always be the interior (without overlap).
752      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
753    o verification/tutorial_global_oce_biogeo:
754      - add preliminary OpenAD setup (still has problems)
755    o pkg/seaice:
756      - turn some parameters for choosing the convergence criterion of
757        the inexact Newton method (JFNK) into runtime parameters for convenience
758      - clean up seaice_calc_viscosities.F: remove/retire two options for
759        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
760        the results of lab_sea/input because a division has been replaced by
761        a multiplication with the reciprocal (sumNorm)
762      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
763        convergence of solver (changes results, of course), and to test some
764        new features
765    o model/src:
766      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
767      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
768      - move forcing adjustment (balancing surface forcing) in specific S/R
769        where might also be applied exchanges (if needed) to forcing arrays.
770    o pkg/shelfice:
771      - allow to specify the Ice-Shelf mass per unit area (instead of
772        shelficeLoadAnomaly) and do the conversion from one to the other
773      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
774        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
775        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
776        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
777      - update isomip experiment forward output (get machine truncation error
778        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
779    o verification/offline_exf_seaice:
780      revise data.seaice in input.thermo and input_ad and update results accordingly
781        HO = 0.2, SEAICE_areaLossFormula = 2,
782        SEAICE_growMeltByConv = .TRUE.,
783        SEAICE_doOpenWaterMelt = .TRUE.,
784      Improve consistency with input.thsice and fix the spurious 500m ice corners
785    o verification/global_ocean.cs32x15:
786      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
787        in icedyn (thsice+seaice-dyn) test and update output.
788    o verification/offline_exf_seaice:
789      - adjust list of tested variables (with testreport) and update
790        standard test output with better slection of monitored fields.
791    o pkg/cd_code:
792      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
793        experiment lab_sea.hb87
794    o tools/genmake2:
795      - change default makedepend from the system default to tools/xmakedepend:
796        When no makedepend is specified, select tools/xmakedepend it the test pass,
797        otherwise select the system default (if exist and pass the test) or
798        try to build cyrus-makedepend ; stop if none of the 3 works.
799    o pkg/exf & pkg/thsice:
800      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
801        for energy content of Precip + RunOff & Evap. Assumes:
802       1) Rain has same temp as Air.
803       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
804       3) Run-Off comes at the temp of surface water (with same Cp)
805       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
806        put directly into Latent Heat flux & should use water-vapor heat capacity.
807       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
808        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
809    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
810        (compile when SEAICE_ALLOW_JFNK is defined)
811    o pkg/thsice:
812      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
813        implementation): move THSICE_AVE call after the advection (called directly
814        from thsice_do_advect.F).
815    o verification/global_ocean.90x40x15 and OpenAD:
816      New experiment for OpenAD is identical to the one in input_ad except that
817        multiDimAdvection=.FALSE.,
818      There is still an issue with this.
819    o pkg/thsice:
820      - account for ice velocity (ocean relative velocity) in turbulent heat flux
821        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
822        and offline_exf_seaice (main test).
823    
824    checkpoint64f (2013/03/31)
825    o verification/OpenAD:
826      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
827    o verification/isomip, pkg/shelfice and OpenAD:
828      - add OpenAD setup to this exp and make shelfice package work with OpenAD
829    o verification/tutorial_global_oce_biogeo:
830      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
831    o verification/offline_exf_seaice:
832      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
833    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
834      - add OpenAD setup to this exp and make ptracers package work with OpenAD
835    o pkg/seaice/seaice_evp.F:
836       mask the asymmetric contribution of the ice-ocean stress (when
837       the turningAngle is non-zero) over open water to avoid stripes
838       in the EVP-solutions after many EVP-substeps. This does not change
839       the verification experiment (because turningAngle=0 in that experiment),
840       but will affect other EVP solutions with turningAngle.ne.0
841    o verification, AD & TLM output:
842      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
843        additions and multiplications which affect results at machine truncation
844        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
845        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
846        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
847        digits of matching.
848    o pkg/seaice:
849       modify lsr-algorithm so that it vectorizes AND converges by using a
850       "zebra" method: split vector loop into two with step size 2; this
851       solves a general convergence problem for the JFNK solver on a vector
852       computer. It has the potential to even improve convergence for
853       non-vector machines, but it does change the results so it is turned
854       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
855       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
856    
857    checkpoint64e (2013/03/05)
858    o pkg/ecco and several verification experiments:
859       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
860       from ecco package, and revert to unified routine in model/src/
861       Adjust verification experiments accordingly, especially gloal_oce_llc90
862       Should conclude long-standing work by Gael to reconsile the_main_loop with
863       ECCO and will enable OpenAD's revolve loop in ECCO setup.
864    o pkg/generic_advdiff:
865      - implement compressible flow method for multi-dim advection (similar to
866        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
867        TAF generates many recomputations) to use it; no yet coded with implicit
868        vertical advection.
869      - change experiment advect_cs (new output) and advect_xy (same output)
870        to test compressible flow multi-dim advection.
871    o pkg/generic_advdiff:
872      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
873        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
874    o pkg/seaice:
875      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
876        bug affects two verification experiments (lab_sea and lab_sea.hb87),
877        recover old (wrong) results by setting noSlipFac = 2. in
878        seaice_calc_strainrates.F;
879      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
880      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
881        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
882      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
883    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
884      - new subroutines seaice_lsr_tridiagu/v
885      - introduce loop bounds i/jmin/max to be able to use a restricted
886        additive Schwarz method, but not used for now.
887      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
888      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
889    o OpenAD support
890       Reorganize S/R call for overall time-stepping loop to facilitate
891       OpenAD revolve loop replacement
892       (new S/R main_do_loop.F)
893    o model/src:
894      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
895      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
896        ADAMS_BASHFORTH2.
897    o pkg/cheapaml:
898      - add new parameter (default=F, same as before) to disable full domain
899        (including land) periodicity in X & Y dir.
900      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
901        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
902        into single S/R CHEAPAML_TIMESTEP.
903    
904    checkpoint64d (2013/02/17)
905    o pkg/monitor (angular momentum):
906      - do not add Eta contribution to the total AM if using rigid-lid;
907      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
908      - horizontal discretisation: compute Zonal wind contribution separately for
909        each component (instead of from cell centered averaged) and use the 4
910        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
911      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
912        FreeSurf) if using vectorInvariant momentum.
913    o model/src (horizontal grid):
914      - move initialisation of all horizontal grid arrays to null value
915        from specific horizontal grid S/R to main S/R INI_GRID;
916      - add 2 new arrays to project model C-grid velocity on to zonal direction
917        (similar to AngleCosC & -AngleSinC but at U and V point location) and
918        compute them in S/R CALC_GRID_ANGLES.
919    o pkg/seaice: replace a hard coded parameter by a runtime parameter
920        SEAICE_JFNK_tolIter
921    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
922        preconditioner for JFNK (run LSR into the overlaps as far as possible,
923        i.e OLx/y-2, but overwrite the solution in the overlaps)
924      - extend loop range in seaice_calc_viscosity
925      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
926      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
927      - slightly modify loops in tridiagonal solver lsr-preconditioner
928      - by default remove the extra exchange in seaice_preconditioner with a
929        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
930      - modify offline_exf_seaice so that old results without RAS are reproduced
931        for output.dyn_jfnk.txt
932      in seaice_fgmres.F (unrelated to RAS)
933      - add a cpp-flag option for a re-ordered mapping (potentially more
934        efficient), but because this changes the results, turn it off by
935        default
936      - replace the save statement by local common blocks
937    o utils/matlab:
938      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
939      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
940        instead of local script "load_cs.m".
941    o pkg/seaice:
942      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
943        to the scalarProductMetric and the unrolling. By chance this does not
944        change the verification experiment, because of the particular domain
945        decomposition
946    o pkg/diagnostics:
947      - change default missing_value from UNSET_RL to -999.
948    o pkg/layers: improve vectorization of layers_fluxcalc.F
949      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
950        time spent in this routine by more than a factor of 3 on an NEC-SX8
951      - step 2: replace search algorithm by a bisection algorithm found in
952        Press et al. Numerical Recipes in Fortran. This algorithm can be
953        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
954        For now, use this algorithm only for TARGET_NEC_SX defined.
955      - moved the search algorithm into a separate subroutine, that is kept
956        within the same file for automatic inlining.
957      - modified catching potential errors
958    o pkg/ecco:
959      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
960    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
961      - modifications for ALLOW_GENTIM2D_CONTROL
962      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
963      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
964      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
965      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
966    o model/src:
967      - account for moist thermodynamics in (dry) potential temperature equation;
968        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
969        and cpl_aim+ocn.
970      - also switch to standard compiler (gfortran, was using ifort previously)
971        for fizhi-cs experiments reference output.
972    o pkg/ctrl:
973      - 1st step toward generic time-varying control variable (2D) via CPP option
974        ALLOW_GENTIM2D_CONTROL
975      - note new namelist ctrl_nml_genarr in data.ctrl
976    o verification/global_ocean.cs32x15:
977      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
978        thsice calling sequence and update "output.icedyn.txt" output file.
979    o pkg/ptracers:
980      - from Ryan A.: code to allow to restart a tracer at regular time interval
981        specifying a reset frequency and a reset-phase (for each tracers).
982    o pkg/thsice:
983      - implement new sequence of calls for thsice+seaice:
984          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
985          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
986      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
987        in CPP_OPTIONS.h) to recover old sequence;
988      - update diagnostics for Intermediate State thsice diagnostics: now filled
989        just before advection (instead of just after advection in old sequence);
990      - update output of experiment offline_exf_seaice (standard test);
991      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
992        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
993    o pkg/aim_v23:
994      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
995      - use standard pkg/mdsio routines to read & write CO2 pickup file;
996      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
997      - Implement new sequence of calls for seaice advection (with thsice and
998        seaice diffusion): do ice advection after ice-Thermodynamic (previously
999        was done before); change aim_do_physics.F (split the bi,bj loops block);
1000      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1001    o pkg/thsice:
1002      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1003        where just seaice diffusion is used without seaice-dynamics.
1004    
1005    checkpoint64c (2013/01/18)
1006    o pkg/seaice:
1007      - add a parameter JFNKres_tFac that can replace JFNKres_t
1008        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1009      - add a line search option to the JFNK solver
1010      - move update of u/vIce and computation of initial residual into a separate
1011        routine (same file); makes the code a little easier to read (?)
1012      - the line search requires computation of the residual and for some reason
1013        I cannot do the update of u/vIce at the beginning of the Newton loop
1014        without changing the results, so we move computation of the new residual
1015        also to the end of the Newton loop, even without the line search
1016    o pkg/mdsio:
1017      - write missing value (corresponding to undefined array value) to meta files;
1018        skip this if missing value is one (UNSET_RL would be a better value for the
1019        case of undefined missing value but it's current the default missing-value);
1020        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1021    o pkg/exf & thsice:
1022      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1023        diagnostics) even when SHORTWAVE_HEATING is #undef;
1024    o verification/cfc_example:
1025      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1026        illustrate how to use it).
1027    o verification/offline_exf_seaice:
1028      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1029        files to only one time-record.
1030      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1031        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1032        snapshot output; same mcPheePiston value as in thsice with
1033        surf-current=0.2m/s.
1034      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1035        initial conditions).
1036    o verification/cfc_example:
1037      - update file "data" with more standard choice (default rotationPeriod,
1038        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1039        set deltaTFreeSurf to deltaTtracer) and update the output.
1040    o pkg/layers:
1041      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1042      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1043    o verification/offline_exf_seaice:
1044      - set all {field}period to zero for constant-in-time forcing (not tested
1045        anywhere else).
1046    o verification/offline_exf_seaice:
1047      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1048      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1049    o model/src:
1050      - implement Finite-Volume method for (hydrostatic) presure gradient
1051        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1052    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1053      - In order to be compatible with the default EVP code, this requires changing
1054        the EVP code around a little; and because any small change immediately
1055        breaks the lab_sea.hb87 verification experiment, the reference output is
1056        updated two times (each time the remaining aggrement was only 2 digits):
1057        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1058        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1059        The adjoint test lab_sea.evp also needed to be updated.
1060      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1061        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1062        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1063        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1064        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1065        kept obscure, because I need to test it a little more.
1066    o pkg/cheapaml:
1067      - fix few incorrect type (_RL/_RS) in subroutine calls.
1068    o pkg/seaice:
1069      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1070        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1071    o model/src:
1072      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1073        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1074        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1075    o pkg/cheapaml:
1076      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1077        update output of experiment cheapAML_box.
1078      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1079        and set them only in one place (cheapaml_readparms.F).
1080      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1081      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1082        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1083    o model/src/the_main_loop.F:
1084      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1085    o pkg/seaice:
1086      - remove legacy branch code.
1087      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1088    o verification/*/code*/SEAICE_OPTIONS.h:
1089      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1090        SEAICE_CAP_HEFF).
1091    o pkg/cheapaml:
1092      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1093        to load new forcing fields.
1094      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1095      - remove switch to "-r8" compiler option (no longer needed) in verification
1096        cheapAML_box, keep same output (small trucation error differences).
1097    o verification/offline_exf_seaice:
1098      - add thermodynamics only test.
1099    o verification/cheapAML_box:
1100      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1101        keep same output (same 14 digits for cg2d).
1102      - switch on "-r8" compiler option (some numerical values are missing
1103        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1104    
1105    checkpoint64b (2012/12/24)
1106    o pkg/cheapaml:
1107      - remove un-used variables (Qnet,EmPmR) from pickup files.
1108      - store tendency of advected variables into cheapaml pickup file
1109        and fix the AB-2 restart.
1110    o verification/offline_exf_seaice and lab_sea adjoint:
1111      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1112      - switch to 4 time steps in offline, consistent with lab_sea.
1113      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1114      - update results after change of experiment seaice.
1115    o pkg/seaice:
1116      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1117        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1118        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1119        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1120    o model/src:
1121      - add run-time parameter to select CG2D solver minimum-residual solution
1122        (in case of a poor convergence).
1123    o pkg/seaice/seaice_lsr.F
1124      - move calculation of matrix coefficients into new
1125        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1126        file; the main purpose of this change is to be able to reuse the code
1127        in S/R SEAICE_PRECONDITIONER
1128      - modify the computation of the residual so that the mass of sea-ice
1129        is not used twice; this simplifies the calculations, but since
1130        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1131        not tested in testreport---this does not affect the testreport results.
1132    o verification/seaice_obcs:
1133      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1134        verification/lab_sea/input.salt_plume; changes results/output.txt*
1135    o model/src:
1136      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1137    o pkg/seaice:
1138      - improve description of parameters in seaice_fgmres.F and start
1139        cleaning up the code
1140      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1141        second argument
1142      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1143        results of offline_exf_seaice.dyn_jfnk
1144      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1145    o pkg/aim_v23:
1146      - fix an other bug in dissipation heating (grid-cell area was missing).
1147    o model/src + pkg/seaice:
1148      - add global (multi-tile) linear solver for pair of tri-diagonal system
1149        along X and Y lines, respectively for U and V component.
1150        Note: 1) MPI and cube-exchange not yet coded.
1151            2) probably not accurate for poorly conditioned / large size problem.
1152      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1153        default: not compiled and not used.
1154    o pkg/seaice:
1155      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1156        introduce bi/bj loops and use global_sum_tile_rl instead of
1157        mpi_allreduce in seaice_fgmres.F
1158      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1159      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1160      - add a verification experiment for JFNK in offline_exf_seaice
1161    o verification:
1162      - change (for now, only fwd test) offline_exf_seaice experiment:
1163        use a re-entrant channel with idealized coastline (trapezoidal shape)
1164        at southern boundary to explore seaice dynamics and thermodynamics
1165        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1166        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1167      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1168    o pkg/exf:
1169      - disable "sstExtrapol" when Nr=1
1170    o verification:
1171      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1172        to test pkg/cheapaml.
1173    o pkg/aim_v23 & pkg/shap_filt:
1174      - fix dissipation heating (erroneous gravity multiplication factor).
1175    o pkg/seaice:
1176      - remove unused field pressPre from jfnk solver
1177      - rename two subroutines in seaice_preconditioner.F
1178    o eesupp/src:
1179       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1180    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1181       - remove wrong parts of the rhs and the lhs (were in there
1182         because I did not understand the concept of this preconditioner)
1183       - add an exchange between u- and v-sweep. This increases communication
1184         by a factor of two but improves the convergence of jfnk. Ideally,
1185         one would like the u- and v-sweep to be independent. So far within
1186         undocumented ifdefs
1187       - reorganize the extra computations for printing the residuals
1188    o tools/genmake2:
1189      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1190        since it's not necessary (and was preventing to use MNC in some cases).
1191    
1192    checkpoint64a (2012/11/16)
1193    o pkg/autodiff:
1194      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1195        autodiff_readparms.F no longer depends on calling order (within
1196        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1197        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1198        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1199    o pkg/obcs:
1200      - adding tidal velocity forcing capability to obcs
1201        for usage example, see verification/seaice_obcs/input.tides
1202    o pkg/seaice:
1203      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1204        SEAICE_LSRrelaxU/V
1205      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1206    o pkg/aim_v23:
1207      - implement heating from friction (bottom friction and stratospheric drag).
1208    o pkg/shap_filt:
1209      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1210        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1211    o model/src:
1212      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1213        time-constant addMass field from file (addMassFile);
1214      - support for heating due to friction (and Kinetic Energy dissipation):
1215        add option, run-time switch and 3-D field array + support code ; each pkg
1216        or S/R can add heating contribution (if there is a sink of KE); the sum is
1217        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1218    o pkg/seaice:
1219      - complete merge of ITD code into seaice_growth.F
1220        from MITgcm_contrib/torge/itd/code/
1221        no verification so far, but Torge Martin tested
1222        "1-D test case and Beaufort set up;
1223        deliver okay results after 1 model year."
1224      - complete merge of SEAICE_SIZE.h into all relevant routines
1225      - move computation of eta at Z-points into calc_viscosities
1226        + introduce global field etaZ
1227        + add different methods for computing etaZ, for now the old
1228          method (simple averages of eta to Z-points) is hardwired
1229        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1230          seaice_preconditioner
1231      - simplify computations for SEAICE_ZETA_SMOOTHREG
1232      - seaice_preconditioner:
1233        + replace one remaining press by pressLoc (mistake)
1234        + adjust printing of residuals
1235      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1236        + add (SEAICE.h) and rename some counters (initiliased in
1237          seaice_init_fixed.F)
1238        + add _BEGIN/END_MASTER (myThid)  around print statements
1239        + print total number of iterations and failures over SEAICE_monFreq
1240          interval to STDOUT
1241      - move control over output-messages by fgmres to seaice_jfnk to save
1242        some operations
1243      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1244        in order to make restarts with sol .ne. zero (fgmres with restarts)
1245        (seaice_jfnk.F, seaice_fgmres.F)
1246      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1247        a serious convergence problem when open boundaries are involved
1248    o pkg/ggl90: fix computation of control volumes for the case of
1249      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1250      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1251    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1252    o pkg/autodiff
1253      - Add inAdMode switch for SEAICEuseDYNAMICS:
1254        SEAICEuseDYNAMICSinAdMode
1255        (extend logic in ADAUTODIFF_INADMODE_SET)
1256    o pkg/seaice
1257      - Step 1 of merging ice-thickness distribution (ITD) code from
1258        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1259        The code implements concept laid out in Thorndike et al. (1975);
1260        code is enabled via CPP flag SEAICE_ITD
1261        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1262        code is not complete yet!!
1263      - SEAICE_SIZE.h now included in almost all seaice routines
1264    o verification (using seaice):
1265      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1266        global_ocean.cs32x15.seaice ; update results.
1267      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1268      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1269        offline_exf_seaice (previously compiling B-grid).
1270    o pkg/exf:
1271      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1272        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1273        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1274    o pkg/layers (adjust changes from Sept 19):
1275      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1276        this allows to remove "layers_maxNum" dimension from all layers arrays.
1277    o pkg/layers (adjust changes from Sept 19):
1278      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1279      - snap-shot extended to all type of layers (not just the 1rst type);
1280      - remove layers variables when corresponding CPP option is undef.
1281    o pkg/layers:
1282      - rename pkg/layers variable and add new output (layer exist & un-weighted
1283        velocity in layer)
1284    o pkg/seaice:
1285      - simplify (?) ocean-drag coefficent computations by using
1286        the same routine in all three solvers (saves some code lines)
1287      - remove global fields DRAGA and DRAGS from C-grid code and
1288        declare them locally in lsr.F (the only place where they are
1289        still used)
1290      - update AD output of lab_sea.evp (very sensitive anyway).
1291    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1292      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1293      and SEAICEuseJFNK=.true. A few things to note:
1294      - involves a FGMRES, that is parallel but very inefficient,
1295        because of many scalar products (global sums) in the Gram-Schmidt
1296        orthogonalization method. Needs to be replaced. Original code
1297        from J.-F. Lemieux
1298      - preconditioner for FGMRES is a stripped down version of LSOR
1299      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1300        preconditioner. For the preconditioner, the default is set to 10.
1301      - Jacobian times vector is computed with finite differences
1302      - marginally related to JFNK-solver: add a smooth regularization for
1303        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1304        2009) for any implicit solver (not implemented for EVP because EVP
1305        does not need this regularization in the first place). Define
1306        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1307    o eesupp/src:
1308      - check in genmake2 that intrinsic S/R flush is available.
1309      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1310      - flush standard & error msg unit before MPI termination
1311      - if debugMode, flush IO unit after printing msg
1312    o pkg/ctrl:
1313      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1314        to ctrl_set_unpack_xyz.
1315    
1316    checkpoint64 (2012/10/09)
1317    o pkg/shelfice
1318      - in mom_fluxform.F, mom_vecinv.F:
1319        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1320        Bug fix KappaRU -> KappaRV
1321        does not change verification/isomip but may change other setups
1322        (presumably constant KappaRU=KappaRV)
1323      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1324    o pkg/obcs:
1325      - fixed some indexing bugs in obcs_seaice_sponge.F
1326      - added obcs relaxation subroutines for HSALT and HSNOW
1327      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1328    o pkg/seaice:
1329      - add "multicategory" parameterization for snow in analogy to ice,
1330        default is off for now.
1331    o pkg/obcs:
1332      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
1333        see verification/seaice_obcs/input.seaiceSponge for example application.
1334      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
1335        index setting by master-thread. This fix multi-threads Pb in previous modifs.
1336    o pkg/layers :
1337      - add diagnostics to pkg/layers
1338      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
1339        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1340    o pkg/generic_advdiff/gad_implicit_r.F :
1341      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1342    o pkg/seaice/seaice_growth.F:
1343      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1344    o pkg/obcs:
1345      - change default setting of OBCS_UVICE_OLD from defined to undef;
1346      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1347        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1348      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1349      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1350        with Southern & Western OB at a tile edge (at least in a simple set-up).
1351    o pkg/obcs:
1352      - change settings of OB index in case OB coincides with tile edge (shared by
1353        2 tiles), so that common OB location is registered by both tiles (instead of
1354        only 1). However, for Southern and Western OB, index value = 0 is not
1355        recognized as valid OB index (=default null value) and needs to be fixed.
1356      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1357      - new parameter "OB_indexNone" for null index value (for now, still zero)
1358        to replace hard-coded null index value of zero.
1359    o pkg/exch2:
1360      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1361        always check buffer-size (but outside the loop); move checking for valid
1362        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1363        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1364    o pkg/ctrl (pack & unpack):
1365      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1366        (locally defined) for different variables (+ remove the variable-specific
1367        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1368        (to be extended to other local file names in ctrl.h).
1369    o pkg/flt:
1370      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1371    o pkg/mdsio:
1372      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1373    o tools/genmake2:
1374      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1375        (added by Alistair in version 1.51 for building without make depend);
1376      - remove Header files list (H_SRC_FILES) from the dependence of targets
1377         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1378        place in version 1.23): this save going through staf when unrelated header
1379        file has been modified.
1380       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1381        "make depend" step, still need to do "make links" before "make adtaf".
1382    o eesupp/src (+ few pkg src files) & genmake2:
1383      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1384      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1385      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1386         upper/lower case ; account for space between "#" and undef/define)
1387    o pkg/flt (with exch2):
1388      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1389      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1390    
1391    checkpoint63s (2012/09/05)
1392    o pkg/ecco:
1393      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1394      - add more relevant #ifdef ALLOW_SMOOTH ones.
1395      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1396    o pkg/ctrl:
1397      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1398        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1399      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1400        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1401        ctrlSmoothCorrel3D (new).
1402        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1403      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1404      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1405        controls when useAtmWind, and vice versa.
1406      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1407      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1408          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1409      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1410          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1411      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1412        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1413    o pkg/smooth:
1414      - remove un-necessary includes.
1415      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1416        Those CPP options were never defined, and not necessary.
1417    o model/src:
1418      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1419      - standard treatment of useSMOOTH.
1420    o pkg/autodiff:
1421      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1422        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1423    o pkg/exch2:
1424      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1425        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1426      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1427        and tiles to process mapping.
1428      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1429        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1430        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1431        from w2_eeboot.F to w2_readparms.F.
1432    o eesupp/src:
1433      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1434        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1435        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1436      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1437        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1438        has been called.
1439      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1440      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1441        (so that on 1 proc, get same myPid independently of usingMPI)
1442      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1443        useCubedSphereExchange with EXCH-1 (safer).
1444      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1445    o pkg/ggl90:
1446      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1447        used in ALLOW_GGL90_SMOOTH code.
1448    o pkg/flt:
1449      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1450        floats at the Southern end of the domain).
1451    o eesupp/inc:
1452      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1453        but not used (and not to be used) anywhere, just for documentation.
1454    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1455      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1456        a) can damage previously written records in any other multi-record files.
1457        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1458    o tools/genmake2:
1459      - define variable MAKE within Makefile and use it in place of 'make';
1460      - update AD_CONFIG.h (if needed) before building any of the executable
1461        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
1462        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
1463      - always print usual warning comment 'this file is automatically generated'
1464        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1465    o pkg/cheapaml:
1466      - updated to correspond to the code used in accepted paper (Nico Wienders).
1467    o pkg/exf:
1468        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1469        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
1470        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
1471    o pkg/exf, autodiff, ctrl, ecco and seaice:
1472        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
1473    o pkg/ctrl, ecco:
1474        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
1475        Depending on useAtmWind, one is inactive, and the other is active (see
1476        exf_getffields.F/exf_getsurfacefluxes.F).
1477    o tools/genmake2:
1478      - improve error msg when failing in 2nd test of check_for_broken_Ff
1479      - fix option '-makefile' short-name (-mf according to genmake2 -help)
1480      - source local config file "genmake_local" just after processing the genmake2
1481        command arguments (previously done before processing arg).
1482    o pkg/grdchk:
1483      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
1484        to this routine from cost_final has been dropped in g_cost_final)
1485      - improve printed information (more explicit msg, no longer using "print *,"
1486         fix fcpertminus printed value).
1487    o model/src:
1488      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
1489        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
1490        this prevents getting cost-funct reset in adinitialise_varia recomputations.
1491    o pkg/dic:
1492      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
1493        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
1494    o pkg/grdchk:
1495      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
1496      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
1497    o pkg/autodiff/ctrl/grdchk :
1498      - attempt to sort out what works and what does not,
1499        with regard to I/O, and to warn/stop accordingly.
1500    o pkg/grdchk:
1501      - attempt to fix grdchk in the case of useSingleCpuIO.
1502      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
1503       statements were moved from grdchk_main.F and into
1504       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
1505      - a global sum is applied to record numbers icvrec/layer
1506       out of grdchk_loc so that they be passed to I/O routines.
1507    o pkg/smooth:
1508      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
1509        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
1510    o verification/testreport:
1511      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
1512      - can also use compressed (gzip) reference output file;
1513      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
1514        to be easier to collect by testreport.
1515      - update existing TLM output (half out-of-date by more than 3 yrs).
1516      - report NETCDF & LAPACK settings (from genmake2) in output dir.
1517      - report run-time in each individual summary (previously only for AD test);
1518        for TLM test, add also TAF version.
1519      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
1520    
1521    checkpoint63r (2012/08/15)
1522    o tools/genmake2:
1523      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
1524    o pkg/ecco/ecco_cost_final.F :
1525      - fix fc print statements (to stdout and costfunction0000) so
1526        that the printed value is always after the global sum.
1527    o pkg/seaice/seaice_dynsolver.F :
1528      - fix ice strength assymptote at SEAICE_area_max<1
1529        (no change for the standard case of SEAICE_area_max=1)
1530    o some cleaning:
1531      - pkg source files: ensure that all *.F files from each pkg included the
1532        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
1533        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
1534        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
1535        includes;
1536      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
1537      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
1538        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
1539        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
1540      - update option-file CPP_OPTIONS.h of all AD experiments:
1541        * no longer include PACKAGES_CONFIG.h ;
1542        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
1543        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
1544          including ECCO_CPPOPTIONS.h).
1545    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
1546      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
1547        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
1548        not necessary accurate).
1549      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
1550        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
1551        deliberately break compilation (a remainder that it needs to be customized)
1552      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
1553      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
1554      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
1555    o tools/genamke2:
1556      - check for lapack.
1557    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
1558      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
1559        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
1560        from both packages.
1561      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
1562      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
1563      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
1564        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
1565    o pkg/cost : add comments to explain special and/or untested setups.
1566    o pkg/exf:
1567      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
1568        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
1569    o verification/*/code_ad:
1570      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
1571      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
1572      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
1573        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
1574    o pkg/seaice :
1575      - added possibility to change ice strength/PRESS0 relationship to
1576        HEFF, according to the following run time parameters
1577        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
1578        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
1579        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
1580    o pkg/ggl90 :
1581      - added run time flag mxlSurfFlag to include the code that ensure
1582        mixing between first and second level (previously included as a comment)
1583    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
1584      - add test of newly added dumpAdByRec=T option where
1585        we write all records to one file per variable.
1586    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
1587      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
1588        to check that this code is ok with taf and compiles in adjoint.
1589    o pkg/autodiff :
1590      - added run time param dumpAdByRec : ad dump format switch.
1591        If true then write all records to one file per variable.
1592        Else write one file per record (remains the default).
1593      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
1594    o pkg/seaice:
1595     - Added SEAICEuseTILT run time switch : if set to
1596       false then omit the tilt term in seaice dynamics.
1597     - Fix free drift calculation.
1598    o pkg/shelfice:
1599      When initializing SHELFICEDragQuadratic, set default to be
1600      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
1601      but retain option to set it independently
1602      (inconsistenty spotted by Veronique Dansereau)
1603    o eesupp/inc:
1604      - in EEPARAMS.h, add real-type constant for some frequently used simple number
1605         (0,1,2,1/2), with name explicitly referring to RS/RL type.
1606    o model/src:
1607      - move balancing of relaxation terms to new S/R balance_relax.F.
1608    o pkg/autodiff:
1609      re-write active I/O high-level (control) S/R:
1610      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
1611      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
1612      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
1613        MDS_READ/WRITE_FIELD); change loops to multi-threads.
1614      - update and merge active_file_control_slice.flow into active_file_control.flow
1615      - update the calls in lower level S/R (active_file.F, active_file_g.F and
1616        active_file_ad.F) keeping the argument list and function unchanged.
1617      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
1618        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
1619      - new low-level active I/O routines, one for each type (RL/RS), for active var
1620        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
1621        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
1622        right type.
1623    o autodiff and RS=real*4:
1624      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
1625        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
1626      - change argument type of 3-D mask argument to _RS to match type in the call
1627        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
1628    o pkg/thsice:
1629      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
1630      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
1631        fresh-water flux: uniform correction or proportional to local precip.
1632    o pkg/ctrl:
1633      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
1634      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
1635                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
1636      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
1637    
1638    checkpoint63q (2012/07/30)
1639    o pkg/autodiff:
1640      note about monitor and snap-shot of ad-variables:
1641      a) need to apply ADEXCH before monitor or output of ad-vars to include
1642       overlap contributions (was done for adjDump but missing for monitor).
1643      b) since ADEXCH implies adding overlap values to interior array, machine
1644       truncation error is expected when adding an ADEXCH call in the middle of
1645       the time-stepping (although mathematically identical).
1646      modifs:
1647      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
1648        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
1649      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
1650        apply ADEXCH before monitor or snap-shot of ad-variables:
1651           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
1652      - implement new method (copy+adexch) for snap-shot and monitor of main model
1653        ad-vars (initially not used by default -> output unchanged).
1654      - change default (set to 2) to use new method and update few output_adm.txt
1655        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
1656        and both tutorial_tracer_adjsens tests).
1657      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
1658        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
1659    o pkg/ctrl:
1660      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
1661      generic control variables via
1662      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
1663      Only required customization should be S/R ctrl_map_ini_genarr.F
1664      (routine in repository contains example)
1665    o pkg/exf:
1666      - fix and refine checking of surface-relaxation setting when using EXF
1667    o verification (adjoint exp):
1668      - reduce length of simulation by half for experiment global_ocean.cs32x15
1669        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
1670    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
1671      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
1672        of KE that can occur with aggressive optimization
1673      + put quadratic bottom drag calculation in separated loops (only done if
1674        using bottomDragQuadratic)
1675    o model/src: CG2D_NSA
1676      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
1677         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
1678      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
1679         change cg2d residual target to be expressed in Wunits (=> do not normalise
1680         RHS ; this fix global_max Pb with TAF); update output.
1681    o verification/tutorial_tracer_adjsens:
1682       improve parameter consistency (and get rid of warnings):
1683       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1684       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1685       - use staggerTimeStep (for stability) in som81; use default rotation period.
1686    o pkg/exch2:
1687      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1688        reset to 0 = 1 long line in X)
1689    o pkg/mdsio:
1690      - fix reading of dimensions from meta file for large-size domain
1691    o model/src:
1692      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1693      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1694        Cubed-Sphere Exch with CS-corners inside the domain;
1695        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1696        globalArea and to set hasWetCSCorners.
1697      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1698        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1699      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1700        useCDscheme and useCubedSphereExchange).
1701    o pkg/seaice/seaice_growth.F :
1702      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1703        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1704        when the previous code was not correct.
1705      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1706      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1707        that term to QNET (essentially to set the melt/freeze water to 0degC).
1708        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1709    o verification/global_ocean.cs32x15/input.seaice :
1710      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1711      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1712      - update results (output.seaice.txt) accordingly.
1713    o verification/lab_sea/input/data.seaice :
1714      - remove SEAICEheatConsFix, which is now be tested
1715        in global_ocean.cs32x15. The presently coded fix
1716        is only consistent with real fresh water + nlfs.
1717      - update results (output.txt) accordingly.
1718    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1719    o AD_CONFIG.h file:
1720      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1721      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1722        add it explicitly in each fortran src file where it is needed.
1723        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1724        thus introducing potentially wrong dependency; therefore, better to include
1725        it only where it's really needed, and after any other included OPTIONS file
1726        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1727        or ALLOW_TANGENTLINEAR_RUN).
1728    
1729    checkpoint63p (2012/07/06)
1730    o pkg/autodiff:
1731      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1732      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1733        which are now read from new parameter file "data.autodiff" (inAdExact
1734        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1735      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1736      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1737        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1738    o verification/tutorial_tracer_adjsens/
1739      - add extra sub-verification which uses "SOM" advection scheme
1740        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1741          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1742        and in data:
1743          multiDimAdvection=.TRUE.,
1744          tempAdvScheme=81,
1745          saltAdvScheme=81,
1746    o model/src:
1747      - introduce ALLOW_BALANCE_RELAX which allow the removal
1748       of the global mean of relaxation terms by setting
1749       balanceThetaClimRelax and balanceSaltClimRelax
1750      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1751       This case is now treated appropriately in seaice_growth.F
1752    o pkg/seaice:
1753      - do balanceEmPmR and balanceQnet based on the net fluxes
1754        (SItflux) that enter the ocean+ice system rather than QNET
1755        and EMPMR. Works best in real fresh water.
1756      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1757        out of the diagnotics bloc, and stored in global arrays.
1758    
1759    checkpoint63o (2012/06/29)
1760    o vertical mixing schemes:
1761      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1762      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1763        to S/R FIND_RHO_SCALAR
1764      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1765        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1766        affects output (vermix.ggl90) at truncation level.
1767    o testreport:
1768      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1769        (nSx,nSy) for the number of threads (from eedata.mth)
1770    o model/src:
1771      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1772        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1773  o verification/tutorial_tracer_adjsens/  o verification/tutorial_tracer_adjsens/
1774    - compile with ALLOW_CG2D_NSA    - compile with ALLOW_CG2D_NSA
1775    - run with nonlinFreeSurf=3    - run with nonlinFreeSurf=3
