4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/exf/exf_check.F
8     - fix a small bug again (originally found by Wentao Liu, now found again)
9     - streamline error output
10    o pkg/streamice and aim_v23:
11      replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
12      Apple's /usr/bin/cpp knows what to do:
13      Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
14      Target: x86_64-apple-darwin13.0.0
15    
16    checkpoint64s (2014/01/05)
17    o tools/adjoint_options:
18      - switch to fastopt.net TAF server (instead of default fastopt.de) for
19        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
20    o model/src:
21      - remove some unnecessary TAF storage directives in forward_step.F and
22        in dynamics.F (note: not always removed by TAF, e.g., double storage
23        of kappaRU,kappaRV in former version of dynamics.F).
24    o model/src & pkg/ptracers:
25      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
26        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
27        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
28      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
29      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
30      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
31    o useSingleCpuInput separates single-CPU input from single-CPU output;
32        for now only implemented for in exf_interp_read.F
33    o verification/advect_xy:
34      - fix missing EXCH call in local version of ini_salt.F and update output.
35    o momentum diagnostics:
36      - fix which deltaT is used in Total-Tendency diagnostics.
37      - fix typo in diagnostics for momentum tendency from AB.
38    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
39        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
40    
41    checkpoint64r (2013/12/08)
42    o verification/*/results:
43      - Update reference output of experiments that were passing with just 13 digits
44         (make it easier to detect future changes in results)
45    o model/src & pkg/ptracers:
46      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
47        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
48        to inside ptracers_integrate.F ; remove ptracers_advection.F
49    o coupling interface pkgs:
50        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
51      - change the config check to test the agreement of Ocean Depth
52        with ATM land/sea mask (instead of ATM orography);
53      - send to coupler the number of coupler time-steps to do for this run:
54        this allows to check for consistency and don't need anymore to be
55        specified in parameter file "data";
56      in coupler:
57      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
58      - improve report to log-file of config setting (pass log-file unit to few S/R)
59    o pkg/compon_communic:
60      - add coupling send/receive for non-tiled integer vector;
61      - add S/R to check and stop if any proc has an error (similar to
62        eesupp/src/stop_if_error.F but single thread and across Comm_World).
63    o pkg/exch2:
64      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
65        through list of all tiles my proc owns.
66    o model/src:
67      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
68        from rTrans) to simplify dependencies (no need to store rTrans anymore in
69        calling S/R); this affects AD results at machine truncation level:
70        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
71        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
72    o tools/build_options:
73      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
74    o coupling interface pkgs:
75        [compon_communic, atm_compon_interf & ocn_compon_interf]
76      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
77        to each S/R that needs it; remove un-used variables.
78      - change component tile registration (cpl_register.F in both compon_interf
79        and mitcomponent_tile_register.F) to pass the full list of tiles
80        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
81      - with pkg/exch2: adopt the same convention used for I/O to define mapping
82        towards coupler global array (unless W2_useE2ioLayOut=F):
83         a) can now use different tiling between atm & ocn comp.
84         b) no needs to modify the run-Off map when changing tiling (was needed
85            even if using the same tiling between atm & ocn).
86         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
87            full land tiles); not yet tested.
88      - check for valid mapping from comp. tile to coupler global array
89      - improve report of tile registration results to log file.
90    o pkg/exch2:
91      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
92        tile-registration (CPL_REGISTER);
93      - activate (un-comment) definition and setting of "W2_tileIndex" list to
94        store the local bi,bj indices of each tile;
95      - also print bi,bj in local report to log file;
96      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
97        Jun 2009 modif of pkg/exch2).
98    o testing on baudelaire:
99      - run 2 tests at a time: no significant slow down (since enough cpu) and
100        get the full set of test done earlier
101      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
102    o model/src/thermodynamics.F and routines called from it:
103      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
104        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
105        velocity (outp) by adding bolus velocity.
106      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
107        mass transport from velocity + lateral grid cell area
108      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
109      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
110     in thermodynamics.F
111      - remove k from thermodynamics.F and move it to temp_integrate.F
112        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
113        loop).
114      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
115        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
116        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
117        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
118      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
119        global_ocean.90x40x15, tutorial_global_oce_biogeo and
120        tutorial_tracer_adjsens (+ TLM output).
121    o tools/OAD_support and (verification/*/) code_oad:
122      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
123        module conversion ; remove unneeded CPP_EEOPTIONS.h.
124      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
125        version (closer to model/inc/CPP_OPTIONS.h).
126    o model/src:
127      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
128        retired list of parameters (routine FREEZE has been replace by surface
129        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
130    o pkg/gmredi:
131      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
132        velocity (same scheme but affects machine truncation) for GM_AdvForm.
133      - update output of FWD experiments: front_relax.bvp,
134        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
135    
136    checkpoint64q (2013/11/17)
137    o verification:
138      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
139        tutorial_global_oce_biogeo and global_ocean.90x40x15.
140      - generate new output (growth & melt) for seaice_itd experiment after
141        updating the input pickup_seaice files (previously wrong).
142    o pkg/cost:
143      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
144        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
145        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_TILE_RL
146          cannot be applied to var in common block).
147        o allows to get results independent of tile-per-proc setting (if using
148          slower GLOBAL_SUM_SEND_RECV option).
149      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
150        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
151        forward gradients: update output).
152      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
153        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
154    o pkg/mom_common:
155      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
156        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
157        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
158        ensure that all field value that are used are set.
159    o tutorial_deep_convection (smag3d):
160      - add missing scaling in mom_calc_smag_3d.F;
161      - set smag3D_coeff in input.smag3d such that results do not change.
162    o pkg/dic:
163      - change dic_cost.F to compute cost on each tile first and then apply
164        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
165        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
166      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
167    o eesupp/src & pkg/mdsio:
168      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
169        (from pkg/mdsio) since they are no longer used for tape IO.
170      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
171        (+ keep a copy in pkg/atm_ocn_coupler).
172    o verification/isomip:
173      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
174    o tools/build_options:
175      - optfile linux_amd64_ifort11, fast (no ieee) case:
176        to get a working restart for all experiments, add "-fp-model source"
177        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
178    
179    checkpoint64p (2013/10/20)
180    o pkg/autodiff:
181      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
182        criteria, return to simple (default) tape IO format.
183    o pkg/mdsio (+ eesupp/src):
184      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
185        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
186      - fix globalFile and singleCpuIO options using simpler global mapping.
187      - new pairs of scatter/gather vector S/R (one for each type, generated from
188        template) corresponding to simpler global mapping.
189      - adread_write.F: switch to new S/R (but leave old calls commented) and write
190        to globalFile when parameter globalFiles is set to True.
191      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
192    o pkg/autodiff:
193      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
194        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
195        missing, just add a STOP if array type do not match.
196    o pkg/exf:
197      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
198         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
199         and rename array obsSIce to exf_iceFraction.
200    o tutorial_deep_convection:
201      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
202        for now all in this exp. code dir.
203      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
204        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
205    o eesupp/src:
206      - added SINGLE_DISK_IO option because reading of parameter files on
207        very large number of processors did not work with existing set-up
208    
209    checkpoint64o (2013/09/25)
210    o pkg/atm_phys & atm_compon_interf:
211      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
212    o tools/build_options:
213      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
214        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
215        remove CPP setting (was identical to genmake2 default).
216    o pkg/gmredi & model/src: Some updating and work done on the residual model.
217      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
218      - fixed up the calculation of the eddy stress and how it is added to the
219        external forcing via taueddy_external_forcing.F
220      - at the moment, it is very experimental and only works with the variable eddy
221        diffusivity calculated in gmredi_k3d.F
222    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
223        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
224    o testreport (& tools/do_tst_2+2):
225      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
226    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
227      - remove CPP='cpp -traditional -P' (this is genmake2 default)
228      - add switch (for big setups) to use 'medium' memory-model (but leave it
229        commented out for now). Note: needed with FC 19 to compile big setups.
230    o pkg/atm_compon_interf:
231      - regroup per field origin (model & pkgs) the coupling storage routines
232         (which accumalate in time each coupling field)
233      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
234        update accordingly + simplify aim_do_physics.F
235    
236    checkpoint64n (2013/08/26)
237    o pkg/bbl:
238      - update formulation to reduce dispersion of tracer properties in bbl
239      - replaced horizontal and vertical transport parameters with velocities
240      - changes results for verification/global_with_exf.yearly
241    o verification/halfpipe_streamice:
242      - change to matrix construction; update both Fwd & AD output.
243    o verification/tutorial_tracer_adjsens:
244      - OpenAD test: switch to vector-invariant momentum since fluxform with
245        rStar causes problems with OpenAD; update output.
246    o tools:
247      - genmake2: define a common prefix for all temp-file names ; move them
248        to local /tmp disk (but would be easy to move them back);
249      - xmakedepend: apply the same switch for temp-files.
250    o pkg/offline:
251      - changes for use with rStar (NLFS): assume that we continue to provide
252        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
253        output files) and apply r* scaling at each time-step (function of the time
254        varying Eta field); use normal pickup files (needed for restart with NLFS).
255    o adjoint with OpenAD:
256      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
257        package openad.  This package has to be compiled for all runs with OpenAD
258        instead of specifying code_oad_all as a modification directory.
259      - link the fortran templates from tools/OAD_support to the build directory
260        for preprocessing to avoid conflicts between different setups compiled
261        simultaneously and simplify cleanup.
262    o pkg/exf:
263      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
264        main model or other pkgs are exchanged in EXF_MAPFIELDS).
265    o model/src:
266      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
267        (similar to do_fields_blocking_exchanges.F).
268    o tools/genmake2:
269      - remove TAF output src code just before calling staf (when not doing a fresh
270        built, will stop if things go wrong with staf).
271      - fix target "adobj" (left from TAF version-2 transition)
272    o pkg/diagnostics:
273      - add a parameter to track the status of pkg/diagnostics activation;
274        this replace/extend the use of logical param "settingDiags" (to check
275        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
276        New S/R to print error message and stop when pkgStatus is not right.
277      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
278    
279    checkpoint64m (2013/08/13)
280    o model/inc:
281      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
282        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
283    o pkg/kpp & aim_v23:
284      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
285    o pkg/seaice:
286      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
287        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
288      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
289    o eesupp/src:
290      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
291        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
292    o switch to TAF version-2:
293      - add flow directives to "freeze" naming convention for ad-routines that
294        are used in I/O routines of adjoint state and associated common blocks
295        that are used in adcommon.h (backward compatible with version-1)
296      - update all ad-optfiles (in tools/adjoint_options + few local to some
297        verification exp) to switch to latest TAF version (currently 2.5.5);
298        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
299        out except for diva).
300      - the major change with TAF version-2 is that both the differentiated
301        routines and the forward routines (new) are returned as part of the TAF
302        output source code. Update genmake2 accordingly.
303      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
304        with version-2 when compared to TLM or FWD gradient); other experiments
305        output show minor changes (machine truncation level); update the few AD &
306        TLM output with 12 matching digits only (some prior to version-2 switch).
307    
308    checkpoint64l (2013/08/05)
309    o model/src:
310      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
311      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
312        when using TAF but only if using OpenAD.
313    o pkg/mom_common+fluxform+vecinv:
314      - always set horiz. viscosity arrays to background value before calling
315        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
316        only when using variable horiz. viscosity (useVariableVisc=T);
317      - simplify mom_vecinv.F (only 1 block for momViscosity).
318    o pkg/mom_common: variable horiz. viscosity in NH code
319      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
320        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
321      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
322        useBiharmonicVisc & useVariableVisc.
323      - fix old bug (already in 1rst implementation of variable horizontal viscosity
324        in calc_gw.F, version 1.27, 2006/06/20):
325        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
326        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
327      - change background horiz viscosity in vertical momentum (gW) to always be
328        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
329        any type of variable viscosity, e.g., viscAh/4Grid)
330      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
331        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
332        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
333        default viscAh,viscA4 is zero).
334    o model/src:
335      - extend length of drC & recip_drC from Nr to Nr+1.
336    o Divided Adjoint (DIVA) with MPI:
337      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
338      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
339        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
340    
341    checkpoint64k (2013/07/23)
342    o tools/OAD_support:
343      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
344        and remove it from genmake2.
345    o tools/build_options:
346      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
347        MPI_HEADER_FILES list (let genmake2 find the missing headers)
348    o verification/halfpipe_streamice:
349      - change to driving stress formulation; update both Fwd & AD output.
350    o tools/genmake2 and Divided Adjoint with MPI:
351      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
352      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
353      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
354        Makefile, which is set by genmake2, and check which mpi-headers are needed.
355        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
356      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
357    o testreport:
358      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
359        perform additional runs (number of additional runs is "add_DIVA_runs" taken
360        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
361    o verification/lab_sea (AD test):
362      - change to test Divided Adjoint Run in this set-up (both standard AD test
363        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
364    o pkg atm_ & ocn_compon_interf:
365      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
366        staggerTimeStep implementation) and disable (retired) corresponding
367        parameter.
368    o pkg/offline:
369      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
370      - add S/R OFFLINE_CHECK to print offline parameter summary
371        and stop if loading a file that is not used;
372      - enable to calculate GMRedi tensor, KPP mixing and convective index
373        when the corresponding file(s) is/are not specified (but pkg is used).
374      - comment out resetting of monitorFreq (to endTime) since it still useful
375        for monitoring CFL numbers and checking offline fields.
376    o OpenAD:
377      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
378        smaller standard output) and generate new (smaller) output (on baudelaire
379        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
380    o model/src:
381      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
382        (where external_forcing_adjust was called) and change list of arguments;
383      - merge external_forcing_adjust.F into external_forcing_surf.F
384      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
385        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
386        previously in file "balance_relax.F", now removed); remove corresponding
387        arrays in FFIELDS.h.
388      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
389        a hack for getting back surfaceForcingS (loaded from file) when using
390        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
391      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
392        (was getting only 11 digits for AD-grad, due to different truncation
393         error in AD code).
394    
395    checkpoint64j (2013/07/04)
396    o pkg/offline:
397      - to enable the use of other features with pkg offline (e.g., obcs),
398        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
399      - comment out "allowFreezing" (now active) in 2 offline testing exp.
400    o pkg/exf ALLOW_RUNOFTEMP
401      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
402      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
403      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
404    o pkg/atm_phys:
405      - allows to add some damping on uVel,vVel (strength only function of k).
406    o verification, ad-tests:
407      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
408        global_ocean_ebm and offline_exf_seaice.thsice.
409    o verification/halfpipe_streamice:
410      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
411        flux input boundary conditions to be ignored; a fix for this bug changed
412        verification results for forward test.
413      - add adjoint test.
414    o pkg/ptracers:
415      - allow to restart without SOM pickup (resetting SOM to zero).
416    o pkg/gmredi:
417      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
418      - It uses mixing length theory and suppression by steering level effects to
419        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
420        to JPO, for more details).
421      - It also uses the diffusivity to calculate an eddy induced streamfunction
422        based on a PV closure (rather than a buoyancy closure as in GM).
423      - New files added to pkg/gmredi:
424        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
425          induced overturning streamfunction (called from gmredi_calc_tensor)
426        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
427          for use in gmredi_k3d
428        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
429          the eddy diffusivity
430    
431    checkpoint64i (2013/06/18)
432    o pkg/cheapaml:
433      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
434        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
435        with pkg/cheapaml.
436    o utils/python: add subpackage for cubed sphere function, first example is
437        simple cs.pcol to plot 2D fields on a map
438    o pkg/streamice:
439      - This is a new package in MITgcm, which solves dynamic equations for ice
440         sheets and ice streams
441      - At the moment it is independent of atmosphere/ocean dynamics, or any
442        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
443        ed that this will change)
444      - There is a new verification exercise that tests it, halfpipe_streamice,
445        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
446        rectangular embayment
447      - halfpipe_streamice is forward-only for now, will have TAF test soon
448      - for questions, email dgoldber@mit.edu
449    o pkg/thsice:
450      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
451        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
452      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
453         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
454      - allow precip from pkg/cheapaml to make snow over seaice.
455    o pkg/cfc:
456      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
457      - remove atmos CFC 2-D arrays from common bloc (now local variables)
458      - change some hard-coded constant to run time parameter for reading and
459        and interpolating atmospheric CFC ; keep same default as previously.
460      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
461      - put arguments in standard order: myTime, myIter, myThid
462      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
463        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
464      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
465      - new routine to print summary of CFC params and check for consistency.
466    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
467      similar to thsice_advdiff.
468      Note that for the B-grid case the routine parameters uc/vc are overwritten.
469    o pkg/cfc:
470      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
471        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
472      - fix interpolation of atmphspheric CFC between Sorthern and Northern
473        hemisphere value.
474    o pkg/seaice:
475      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
476    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
477                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
478      - requires an additional time level that is stored in the pickup
479      - you can start with AB2 from a pickup without this time level with
480        pickupStrictlyMatch = .false.
481    
482    checkpoint64h (2013/05/26)
483    o pkg/cheapaml:
484      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
485        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
486      - consistent treatment of uWind,vWind location: assume everywhere in
487        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
488        (Note: was already the case for Tair,Qair advection);
489        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
490      - compute diabatic forcing only in the interior (excluding overlap regions)
491      - fill in array "Qsw" (for short-wave heating);
492      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
493        before any update (consistent with MITgcm state var diagnostics);
494      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
495        non periodic ; + adjusted for uWind,vWind (C-grid).
496    o pkg/seaice:
497      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
498        add explicitly pkg/exf in experiments that currently use pkg/seaice.
499      - allows to compile pkg/seaice without pkg/exf.
500    o tools/OAD_support:
501      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
502        of array "ourStepOf" in function rvNextAction (revolve.F90).
503    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
504      - change pkg name (to be used with other atmospheric physics pkg)
505        but by-pass CVS when making the new pkg so that we keep the CVS history.
506    o pkg/offline:
507      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
508        (previously called from pkg/dic_surfforcing_init.F)
509    o model/src:
510      - re-order sequence of calls within packages_init_variables.F, using
511        standard order, except for:
512         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
513         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
514    o new pkg: atm_phys
515      - add entry point and source code (previously in contrib
516          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
517        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
518      - re-order sequence of calls within packages_readparms.F,
519         packages_init_fixed.F and packages_write_pickup.F
520        (but skip packages_init_variables.F because of TAF issues).
521      - update contrib/*/atm_gray/ experiment.
522    o pkg/seaice (ITD code):
523      - simplify and fix the writing of pickup-files for ITD case
524    o pkg/seaice (ITD code):
525      - introduce floe size dependent lateral melt for ITD case;
526      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
527      - update seaice_itd experiment main output.
528    o pkg/thsice:
529      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
530        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
531        changed accordingly pkg/atm2d.
532    
533    checkpoint64g (2013/05/01)
534    o pkg/exf ALLOW_RUNOFTEMP
535      - if defined,  river and glacier runoff temperature can be read-in from
536        runoftempfile; runoftempfile needs to have same format as runofffile
537    o pkg/thsice (& pkg/bulk_force):
538      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
539        for energy content of Precip + RunOff & Evap (like with pkg/exf).
540      - change computation domain to always be the interior (without overlap).
541      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
542    o verification/tutorial_global_oce_biogeo:
543      - add preliminary OpenAD setup (still has problems)
544    o pkg/seaice:
545      - turn some parameters for choosing the convergence criterion of
546        the inexact Newton method (JFNK) into runtime parameters for convenience
547      - clean up seaice_calc_viscosities.F: remove/retire two options for
548        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
549        the results of lab_sea/input because a division has been replaced by
550        a multiplication with the reciprocal (sumNorm)
551      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
552        convergence of solver (changes results, of course), and to test some
553        new features
554    o model/src:
555      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
556      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
557      - move forcing adjustment (balancing surface forcing) in specific S/R
558        where might also be applied exchanges (if needed) to forcing arrays.
559    o pkg/shelfice:
560      - allow to specify the Ice-Shelf mass per unit area (instead of
561        shelficeLoadAnomaly) and do the conversion from one to the other
562      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
563        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
564        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
565        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
566      - update isomip experiment forward output (get machine truncation error
567        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
568    o verification/offline_exf_seaice:
569      revise data.seaice in input.thermo and input_ad and update results accordingly
570        HO = 0.2, SEAICE_areaLossFormula = 2,
571        SEAICE_growMeltByConv = .TRUE.,
572        SEAICE_doOpenWaterMelt = .TRUE.,
573      Improve consistency with input.thsice and fix the spurious 500m ice corners
574    o verification/global_ocean.cs32x15:
575      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
576        in icedyn (thsice+seaice-dyn) test and update output.
577    o verification/offline_exf_seaice:
578      - adjust list of tested variables (with testreport) and update
579        standard test output with better slection of monitored fields.
580    o pkg/cd_code:
581      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
582        experiment lab_sea.hb87
583    o tools/genmake2:
584      - change default makedepend from the system default to tools/xmakedepend:
585        When no makedepend is specified, select tools/xmakedepend it the test pass,
586        otherwise select the system default (if exist and pass the test) or
587        try to build cyrus-makedepend ; stop if none of the 3 works.
588    o pkg/exf & pkg/thsice:
589      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
590        for energy content of Precip + RunOff & Evap. Assumes:
591       1) Rain has same temp as Air.
592       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
593       3) Run-Off comes at the temp of surface water (with same Cp)
594       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
595        put directly into Latent Heat flux & should use water-vapor heat capacity.
596       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
597        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
598    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
599        (compile when SEAICE_ALLOW_JFNK is defined)
600    o pkg/thsice:
601      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
602        implementation): move THSICE_AVE call after the advection (called directly
603        from thsice_do_advect.F).
604    o verification/global_ocean.90x40x15 and OpenAD:
605      New experiment for OpenAD is identical to the one in input_ad except that
606        multiDimAdvection=.FALSE.,
607      There is still an issue with this.
608    o pkg/thsice:
609      - account for ice velocity (ocean relative velocity) in turbulent heat flux
610        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
611        and offline_exf_seaice (main test).
612    
613    checkpoint64f (2013/03/31)
614    o verification/OpenAD:
615      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
616    o verification/isomip, pkg/shelfice and OpenAD:
617      - add OpenAD setup to this exp and make shelfice package work with OpenAD
618    o verification/tutorial_global_oce_biogeo:
619      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
620    o verification/offline_exf_seaice:
621      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
622    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
623      - add OpenAD setup to this exp and make ptracers package work with OpenAD
624    o pkg/seaice/seaice_evp.F:
625       mask the asymmetric contribution of the ice-ocean stress (when
626       the turningAngle is non-zero) over open water to avoid stripes
627       in the EVP-solutions after many EVP-substeps. This does not change
628       the verification experiment (because turningAngle=0 in that experiment),
629       but will affect other EVP solutions with turningAngle.ne.0
630    o verification, AD & TLM output:
631      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
632        additions and multiplications which affect results at machine truncation
633        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
634        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
635        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
636        digits of matching.
637    o pkg/seaice:
638       modify lsr-algorithm so that it vectorizes AND converges by using a
639       "zebra" method: split vector loop into two with step size 2; this
640       solves a general convergence problem for the JFNK solver on a vector
641       computer. It has the potential to even improve convergence for
642       non-vector machines, but it does change the results so it is turned
643       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
644       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
645    
646    checkpoint64e (2013/03/05)
647    o pkg/ecco and several verification experiments:
648       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
649       from ecco package, and revert to unified routine in model/src/
650       Adjust verification experiments accordingly, especially gloal_oce_llc90
651       Should conclude long-standing work by Gael to reconsile the_main_loop with
652       ECCO and will enable OpenAD's revolve loop in ECCO setup.
653    o pkg/generic_advdiff:
654      - implement compressible flow method for multi-dim advection (similar to
655        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
656        TAF generates many recomputations) to use it; no yet coded with implicit
657        vertical advection.
658      - change experiment advect_cs (new output) and advect_xy (same output)
659        to test compressible flow multi-dim advection.
660    o pkg/generic_advdiff:
661      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
662        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
663    o pkg/seaice:
664      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
665        bug affects two verification experiments (lab_sea and lab_sea.hb87),
666        recover old (wrong) results by setting noSlipFac = 2. in
667        seaice_calc_strainrates.F;
668      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
669      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
670        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
671      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
672    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
673      - new subroutines seaice_lsr_tridiagu/v
674      - introduce loop bounds i/jmin/max to be able to use a restricted
675        additive Schwarz method, but not used for now.
676      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
677      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
678    o OpenAD support
679       Reorganize S/R call for overall time-stepping loop to facilitate
680       OpenAD revolve loop replacement
681       (new S/R main_do_loop.F)
682    o model/src:
683      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
684      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
685        ADAMS_BASHFORTH2.
686    o pkg/cheapaml:
687      - add new parameter (default=F, same as before) to disable full domain
688        (including land) periodicity in X & Y dir.
689      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
690        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
691        into single S/R CHEAPAML_TIMESTEP.
692    
693    checkpoint64d (2013/02/17)
694    o pkg/monitor (angular momentum):
695      - do not add Eta contribution to the total AM if using rigid-lid;
696      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
697      - horizontal discretisation: compute Zonal wind contribution separately for
698        each component (instead of from cell centered averaged) and use the 4
699        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
700      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
701        FreeSurf) if using vectorInvariant momentum.
702    o model/src (horizontal grid):
703      - move initialisation of all horizontal grid arrays to null value
704        from specific horizontal grid S/R to main S/R INI_GRID;
705      - add 2 new arrays to project model C-grid velocity on to zonal direction
706        (similar to AngleCosC & -AngleSinC but at U and V point location) and
707        compute them in S/R CALC_GRID_ANGLES.
708    o pkg/seaice: replace a hard coded parameter by a runtime parameter
709        SEAICE_JFNK_tolIter
710    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
711        preconditioner for JFNK (run LSR into the overlaps as far as possible,
712        i.e OLx/y-2, but overwrite the solution in the overlaps)
713      - extend loop range in seaice_calc_viscosity
714      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
715      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
716      - slightly modify loops in tridiagonal solver lsr-preconditioner
717      - by default remove the extra exchange in seaice_preconditioner with a
718        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
719      - modify offline_exf_seaice so that old results without RAS are reproduced
720        for output.dyn_jfnk.txt
721      in seaice_fgmres.F (unrelated to RAS)
722      - add a cpp-flag option for a re-ordered mapping (potentially more
723        efficient), but because this changes the results, turn it off by
724        default
725      - replace the save statement by local common blocks
726    o utils/matlab:
727      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
728      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
729        instead of local script "load_cs.m".
730    o pkg/seaice:
731      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
732        to the scalarProductMetric and the unrolling. By chance this does not
733        change the verification experiment, because of the particular domain
734        decomposition
735    o pkg/diagnostics:
736      - change default missing_value from UNSET_RL to -999.
737    o pkg/layers: improve vectorization of layers_fluxcalc.F
738      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
739        time spent in this routine by more than a factor of 3 on an NEC-SX8
740      - step 2: replace search algorithm by a bisection algorithm found in
741        Press et al. Numerical Recipes in Fortran. This algorithm can be
742        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
743        For now, use this algorithm only for TARGET_NEC_SX defined.
744      - moved the search algorithm into a separate subroutine, that is kept
745        within the same file for automatic inlining.
746      - modified catching potential errors
747    o pkg/ecco:
748      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
749    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
750      - modifications for ALLOW_GENTIM2D_CONTROL
751      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
752      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
753      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
754      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
755    o model/src:
756      - account for moist thermodynamics in (dry) potential temperature equation;
757        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
758        and cpl_aim+ocn.
759      - also switch to standard compiler (gfortran, was using ifort previously)
760        for fizhi-cs experiments reference output.
761    o pkg/ctrl:
762      - 1st step toward generic time-varying control variable (2D) via CPP option
763        ALLOW_GENTIM2D_CONTROL
764      - note new namelist ctrl_nml_genarr in data.ctrl
765    o verification/global_ocean.cs32x15:
766      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
767        thsice calling sequence and update "output.icedyn.txt" output file.
768    o pkg/ptracers:
769      - from Ryan A.: code to allow to restart a tracer at regular time interval
770        specifying a reset frequency and a reset-phase (for each tracers).
771    o pkg/thsice:
772      - implement new sequence of calls for thsice+seaice:
773          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
774          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
775      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
776        in CPP_OPTIONS.h) to recover old sequence;
777      - update diagnostics for Intermediate State thsice diagnostics: now filled
778        just before advection (instead of just after advection in old sequence);
779      - update output of experiment offline_exf_seaice (standard test);
780      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
781        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
782    o pkg/aim_v23:
783      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
784      - use standard pkg/mdsio routines to read & write CO2 pickup file;
785      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
786      - Implement new sequence of calls for seaice advection (with thsice and
787        seaice diffusion): do ice advection after ice-Thermodynamic (previously
788        was done before); change aim_do_physics.F (split the bi,bj loops block);
789      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
790    o pkg/thsice:
791      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
792        where just seaice diffusion is used without seaice-dynamics.
793    
794    checkpoint64c (2013/01/18)
795    o pkg/seaice:
796      - add a parameter JFNKres_tFac that can replace JFNKres_t
797        (= JFNKres_tFac*JFNKresidual before JFNK solver)
798      - add a line search option to the JFNK solver
799      - move update of u/vIce and computation of initial residual into a separate
800        routine (same file); makes the code a little easier to read (?)
801      - the line search requires computation of the residual and for some reason
802        I cannot do the update of u/vIce at the beginning of the Newton loop
803        without changing the results, so we move computation of the new residual
804        also to the end of the Newton loop, even without the line search
805    o pkg/mdsio:
806      - write missing value (corresponding to undefined array value) to meta files;
807        skip this if missing value is one (UNSET_RL would be a better value for the
808        case of undefined missing value but it's current the default missing-value);
809        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
810    o pkg/exf & thsice:
811      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
812        diagnostics) even when SHORTWAVE_HEATING is #undef;
813    o verification/cfc_example:
814      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
815        illustrate how to use it).
816    o verification/offline_exf_seaice:
817      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
818        files to only one time-record.
819      in input.thermo: narrow the 2 bands of low initial ice-concentration near
820        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
821        snapshot output; same mcPheePiston value as in thsice with
822        surf-current=0.2m/s.
823      in input.thsice: similar set-up as in input.thermo (channel with same seaice
824        initial conditions).
825    o verification/cfc_example:
826      - update file "data" with more standard choice (default rotationPeriod,
827        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
828        set deltaTFreeSurf to deltaTtracer) and update the output.
829    o pkg/layers:
830      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
831      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
832    o verification/offline_exf_seaice:
833      - set all {field}period to zero for constant-in-time forcing (not tested
834        anywhere else).
835    o verification/offline_exf_seaice:
836      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
837      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
838    o model/src:
839      - implement Finite-Volume method for (hydrostatic) presure gradient
840        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
841    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
842      - In order to be compatible with the default EVP code, this requires changing
843        the EVP code around a little; and because any small change immediately
844        breaks the lab_sea.hb87 verification experiment, the reference output is
845        updated two times (each time the remaining aggrement was only 2 digits):
846        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
847        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
848        The adjoint test lab_sea.evp also needed to be updated.
849      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
850        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
851        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
852        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
853        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
854        kept obscure, because I need to test it a little more.
855    o pkg/cheapaml:
856      - fix few incorrect type (_RL/_RS) in subroutine calls.
857    o pkg/seaice:
858      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
859        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
860    o model/src:
861      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
862        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
863        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
864    o pkg/cheapaml:
865      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
866        update output of experiment cheapAML_box.
867      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
868        and set them only in one place (cheapaml_readparms.F).
869      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
870      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
871        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
872    o model/src/the_main_loop.F:
873      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
874    o pkg/seaice:
875      - remove legacy branch code.
876      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
877    o verification/*/code*/SEAICE_OPTIONS.h:
878      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
879        SEAICE_CAP_HEFF).
880    o pkg/cheapaml:
881      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
882        to load new forcing fields.
883      - add missing "_d 0" where it's needed; + some editing (improve indentation).
884      - remove switch to "-r8" compiler option (no longer needed) in verification
885        cheapAML_box, keep same output (small trucation error differences).
886    o verification/offline_exf_seaice:
887      - add thermodynamics only test.
888    o verification/cheapAML_box:
889      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
890        keep same output (same 14 digits for cg2d).
891      - switch on "-r8" compiler option (some numerical values are missing
892        the "_d 0") and update output (only 6 digits for cg2d were preserved).
893    
894    checkpoint64b (2012/12/24)
895    o pkg/cheapaml:
896      - remove un-used variables (Qnet,EmPmR) from pickup files.
897      - store tendency of advected variables into cheapaml pickup file
898        and fix the AB-2 restart.
899    o verification/offline_exf_seaice and lab_sea adjoint:
900      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
901      - switch to 4 time steps in offline, consistent with lab_sea.
902      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
903      - update results after change of experiment seaice.
904    o pkg/seaice:
905      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
906        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
907        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
908        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
909    o model/src:
910      - add run-time parameter to select CG2D solver minimum-residual solution
911        (in case of a poor convergence).
912    o pkg/seaice/seaice_lsr.F
913      - move calculation of matrix coefficients into new
914        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
915        file; the main purpose of this change is to be able to reuse the code
916        in S/R SEAICE_PRECONDITIONER
917      - modify the computation of the residual so that the mass of sea-ice
918        is not used twice; this simplifies the calculations, but since
919        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
920        not tested in testreport---this does not affect the testreport results.
921    o verification/seaice_obcs:
922      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
923        verification/lab_sea/input.salt_plume; changes results/output.txt*
924    o model/src:
925      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
926    o pkg/seaice:
927      - improve description of parameters in seaice_fgmres.F and start
928        cleaning up the code
929      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
930        second argument
931      - add a metric based on grid cell area to SEAICE_SCALPROD; update
932        results of offline_exf_seaice.dyn_jfnk
933      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
934    o pkg/aim_v23:
935      - fix an other bug in dissipation heating (grid-cell area was missing).
936    o model/src + pkg/seaice:
937      - add global (multi-tile) linear solver for pair of tri-diagonal system
938        along X and Y lines, respectively for U and V component.
939        Note: 1) MPI and cube-exchange not yet coded.
940            2) probably not accurate for poorly conditioned / large size problem.
941      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
942        default: not compiled and not used.
943    o pkg/seaice:
944      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
945        introduce bi/bj loops and use global_sum_tile_rl instead of
946        mpi_allreduce in seaice_fgmres.F
947      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
948      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
949      - add a verification experiment for JFNK in offline_exf_seaice
950    o verification:
951      - change (for now, only fwd test) offline_exf_seaice experiment:
952        use a re-entrant channel with idealized coastline (trapezoidal shape)
953        at southern boundary to explore seaice dynamics and thermodynamics
954        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
955        secondary test (input.thsice) use thermodynamics only with SST relaxation.
956      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
957    o pkg/exf:
958      - disable "sstExtrapol" when Nr=1
959    o verification:
960      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
961        to test pkg/cheapaml.
962    o pkg/aim_v23 & pkg/shap_filt:
963      - fix dissipation heating (erroneous gravity multiplication factor).
964    o pkg/seaice:
965      - remove unused field pressPre from jfnk solver
966      - rename two subroutines in seaice_preconditioner.F
967    o eesupp/src:
968       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
969    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
970       - remove wrong parts of the rhs and the lhs (were in there
971         because I did not understand the concept of this preconditioner)
972       - add an exchange between u- and v-sweep. This increases communication
973         by a factor of two but improves the convergence of jfnk. Ideally,
974         one would like the u- and v-sweep to be independent. So far within
975         undocumented ifdefs
976       - reorganize the extra computations for printing the residuals
977    o tools/genmake2:
978      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
979        since it's not necessary (and was preventing to use MNC in some cases).
980    
981    checkpoint64a (2012/11/16)
982    o pkg/autodiff:
983      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
984        autodiff_readparms.F no longer depends on calling order (within
985        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
986        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
987        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
988    o pkg/obcs:
989      - adding tidal velocity forcing capability to obcs
990        for usage example, see verification/seaice_obcs/input.tides
991    o pkg/seaice:
992      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
993        SEAICE_LSRrelaxU/V
994      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
995    o pkg/aim_v23:
996      - implement heating from friction (bottom friction and stratospheric drag).
997    o pkg/shap_filt:
998      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
999        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1000    o model/src:
1001      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1002        time-constant addMass field from file (addMassFile);
1003      - support for heating due to friction (and Kinetic Energy dissipation):
1004        add option, run-time switch and 3-D field array + support code ; each pkg
1005        or S/R can add heating contribution (if there is a sink of KE); the sum is
1006        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1007    o pkg/seaice:
1008      - complete merge of ITD code into seaice_growth.F
1009        from MITgcm_contrib/torge/itd/code/
1010        no verification so far, but Torge Martin tested
1011        "1-D test case and Beaufort set up;
1012        deliver okay results after 1 model year."
1013      - complete merge of SEAICE_SIZE.h into all relevant routines
1014      - move computation of eta at Z-points into calc_viscosities
1015        + introduce global field etaZ
1016        + add different methods for computing etaZ, for now the old
1017          method (simple averages of eta to Z-points) is hardwired
1018        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1019          seaice_preconditioner
1020      - simplify computations for SEAICE_ZETA_SMOOTHREG
1021      - seaice_preconditioner:
1022        + replace one remaining press by pressLoc (mistake)
1023        + adjust printing of residuals
1024      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1025        + add (SEAICE.h) and rename some counters (initiliased in
1026          seaice_init_fixed.F)
1027        + add _BEGIN/END_MASTER (myThid)  around print statements
1028        + print total number of iterations and failures over SEAICE_monFreq
1029          interval to STDOUT
1030      - move control over output-messages by fgmres to seaice_jfnk to save
1031        some operations
1032      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1033        in order to make restarts with sol .ne. zero (fgmres with restarts)
1034        (seaice_jfnk.F, seaice_fgmres.F)
1035      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1036        a serious convergence problem when open boundaries are involved
1037    o pkg/ggl90: fix computation of control volumes for the case of
1038      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1039      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1040    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1041    o pkg/autodiff
1042      - Add inAdMode switch for SEAICEuseDYNAMICS:
1043        SEAICEuseDYNAMICSinAdMode
1044        (extend logic in ADAUTODIFF_INADMODE_SET)
1045    o pkg/seaice
1046      - Step 1 of merging ice-thickness distribution (ITD) code from
1047        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1048        The code implements concept laid out in Thorndike et al. (1975);
1049        code is enabled via CPP flag SEAICE_ITD
1050        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1051        code is not complete yet!!
1052      - SEAICE_SIZE.h now included in almost all seaice routines
1053    o verification (using seaice):
1054      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1055        global_ocean.cs32x15.seaice ; update results.
1056      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1057      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1058        offline_exf_seaice (previously compiling B-grid).
1059    o pkg/exf:
1060      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1061        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1062        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1063    o pkg/layers (adjust changes from Sept 19):
1064      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1065        this allows to remove "layers_maxNum" dimension from all layers arrays.
1066    o pkg/layers (adjust changes from Sept 19):
1067      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1068      - snap-shot extended to all type of layers (not just the 1rst type);
1069      - remove layers variables when corresponding CPP option is undef.
1070    o pkg/layers:
1071      - rename pkg/layers variable and add new output (layer exist & un-weighted
1072        velocity in layer)
1073    o pkg/seaice:
1074      - simplify (?) ocean-drag coefficent computations by using
1075        the same routine in all three solvers (saves some code lines)
1076      - remove global fields DRAGA and DRAGS from C-grid code and
1077        declare them locally in lsr.F (the only place where they are
1078        still used)
1079      - update AD output of lab_sea.evp (very sensitive anyway).
1080    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1081      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1082      and SEAICEuseJFNK=.true. A few things to note:
1083      - involves a FGMRES, that is parallel but very inefficient,
1084        because of many scalar products (global sums) in the Gram-Schmidt
1085        orthogonalization method. Needs to be replaced. Original code
1086        from J.-F. Lemieux
1087      - preconditioner for FGMRES is a stripped down version of LSOR
1088      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1089        preconditioner. For the preconditioner, the default is set to 10.
1090      - Jacobian times vector is computed with finite differences
1091      - marginally related to JFNK-solver: add a smooth regularization for
1092        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1093        2009) for any implicit solver (not implemented for EVP because EVP
1094        does not need this regularization in the first place). Define
1095        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1096    o eesupp/src:
1097      - check in genmake2 that intrinsic S/R flush is available.
1098      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1099      - flush standard & error msg unit before MPI termination
1100      - if debugMode, flush IO unit after printing msg
1101    o pkg/ctrl:
1102      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1103        to ctrl_set_unpack_xyz.
1104    
1105    checkpoint64 (2012/10/09)
1106    o pkg/shelfice
1107      - in mom_fluxform.F, mom_vecinv.F:
1108        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1109        Bug fix KappaRU -> KappaRV
1110        does not change verification/isomip but may change other setups
1111        (presumably constant KappaRU=KappaRV)
1112      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1113    o pkg/obcs:
1114      - fixed some indexing bugs in obcs_seaice_sponge.F
1115      - added obcs relaxation subroutines for HSALT and HSNOW
1116      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1117    o pkg/seaice:
1118      - add "multicategory" parameterization for snow in analogy to ice,
1119        default is off for now.
1120    o pkg/obcs:
1121      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
1122        see verification/seaice_obcs/input.seaiceSponge for example application.
1123      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
1124        index setting by master-thread. This fix multi-threads Pb in previous modifs.
1125    o pkg/layers :
1126      - add diagnostics to pkg/layers
1127      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
1128        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1129    o pkg/generic_advdiff/gad_implicit_r.F :
1130      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1131    o pkg/seaice/seaice_growth.F:
1132      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1133    o pkg/obcs:
1134      - change default setting of OBCS_UVICE_OLD from defined to undef;
1135      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1136        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1137      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1138      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1139        with Southern & Western OB at a tile edge (at least in a simple set-up).
1140    o pkg/obcs:
1141      - change settings of OB index in case OB coincides with tile edge (shared by
1142        2 tiles), so that common OB location is registered by both tiles (instead of
1143        only 1). However, for Southern and Western OB, index value = 0 is not
1144        recognized as valid OB index (=default null value) and needs to be fixed.
1145      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1146      - new parameter "OB_indexNone" for null index value (for now, still zero)
1147        to replace hard-coded null index value of zero.
1148    o pkg/exch2:
1149      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1150        always check buffer-size (but outside the loop); move checking for valid
1151        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1152        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1153    o pkg/ctrl (pack & unpack):
1154      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1155        (locally defined) for different variables (+ remove the variable-specific
1156        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1157        (to be extended to other local file names in ctrl.h).
1158    o pkg/flt:
1159      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1160    o pkg/mdsio:
1161      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1162    o tools/genmake2:
1163      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1164        (added by Alistair in version 1.51 for building without make depend);
1165      - remove Header files list (H_SRC_FILES) from the dependence of targets
1166         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1167        place in version 1.23): this save going through staf when unrelated header
1168        file has been modified.
1169       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1170        "make depend" step, still need to do "make links" before "make adtaf".
1171    o eesupp/src (+ few pkg src files) & genmake2:
1172      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1173      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1174      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1175         upper/lower case ; account for space between "#" and undef/define)
1176    o pkg/flt (with exch2):
1177      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1178      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1179    
1180    checkpoint63s (2012/09/05)
1181    o pkg/ecco:
1182      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1183      - add more relevant #ifdef ALLOW_SMOOTH ones.
1184      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1185    o pkg/ctrl:
1186      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1187        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1188      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1189        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1190        ctrlSmoothCorrel3D (new).
1191        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1192      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1193      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1194        controls when useAtmWind, and vice versa.
1195      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1196      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1197          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1198      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1199          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1200      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1201        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1202    o pkg/smooth:
1203      - remove un-necessary includes.
1204      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1205        Those CPP options were never defined, and not necessary.
1206    o model/src:
1207      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1208      - standard treatment of useSMOOTH.
1209    o pkg/autodiff:
1210      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1211        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1212    o pkg/exch2:
1213      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1214        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1215      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1216        and tiles to process mapping.
1217      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1218        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1219        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1220        from w2_eeboot.F to w2_readparms.F.
1221    o eesupp/src:
1222      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1223        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1224        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1225      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1226        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1227        has been called.
1228      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1229      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1230        (so that on 1 proc, get same myPid independently of usingMPI)
1231      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1232        useCubedSphereExchange with EXCH-1 (safer).
1233      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1234    o pkg/ggl90:
1235      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1236        used in ALLOW_GGL90_SMOOTH code.
1237    o pkg/flt:
1238      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1239        floats at the Southern end of the domain).
1240    o eesupp/inc:
1241      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1242        but not used (and not to be used) anywhere, just for documentation.
1243    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1244      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1245        a) can damage previously written records in any other multi-record files.
1246        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1247    o tools/genmake2:
1248      - define variable MAKE within Makefile and use it in place of 'make';
1249      - update AD_CONFIG.h (if needed) before building any of the executable
1250        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
1251        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
1252      - always print usual warning comment 'this file is automatically generated'
1253        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1254    o pkg/cheapaml:
1255      - updated to correspond to the code used in accepted paper (Nico Wienders).
1256    o pkg/exf:
1257        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1258        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
1259        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
1260    o pkg/exf, autodiff, ctrl, ecco and seaice:
1261        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
1262    o pkg/ctrl, ecco:
1263        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
1264        Depending on useAtmWind, one is inactive, and the other is active (see
1265        exf_getffields.F/exf_getsurfacefluxes.F).
1266    o tools/genmake2:
1267      - improve error msg when failing in 2nd test of check_for_broken_Ff
1268      - fix option '-makefile' short-name (-mf according to genmake2 -help)
1269      - source local config file "genmake_local" just after processing the genmake2
1270        command arguments (previously done before processing arg).
1271    o pkg/grdchk:
1272      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
1273        to this routine from cost_final has been dropped in g_cost_final)
1274      - improve printed information (more explicit msg, no longer using "print *,"
1275         fix fcpertminus printed value).
1276    o model/src:
1277      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
1278        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
1279        this prevents getting cost-funct reset in adinitialise_varia recomputations.
1280    o pkg/dic:
1281      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
1282        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
1283    o pkg/grdchk:
1284      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
1285      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
1286    o pkg/autodiff/ctrl/grdchk :
1287      - attempt to sort out what works and what does not,
1288        with regard to I/O, and to warn/stop accordingly.
1289    o pkg/grdchk:
1290      - attempt to fix grdchk in the case of useSingleCpuIO.
1291      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
1292       statements were moved from grdchk_main.F and into
1293       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
1294      - a global sum is applied to record numbers icvrec/layer
1295       out of grdchk_loc so that they be passed to I/O routines.
1296    o pkg/smooth:
1297      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
1298        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
1299    o verification/testreport:
1300      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
1301      - can also use compressed (gzip) reference output file;
1302      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
1303        to be easier to collect by testreport.
1304      - update existing TLM output (half out-of-date by more than 3 yrs).
1305      - report NETCDF & LAPACK settings (from genmake2) in output dir.
1306      - report run-time in each individual summary (previously only for AD test);
1307        for TLM test, add also TAF version.
1308      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
1309    
1310    checkpoint63r (2012/08/15)
1311    o tools/genmake2:
1312      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
1313    o pkg/ecco/ecco_cost_final.F :
1314      - fix fc print statements (to stdout and costfunction0000) so
1315        that the printed value is always after the global sum.
1316    o pkg/seaice/seaice_dynsolver.F :
1317      - fix ice strength assymptote at SEAICE_area_max<1
1318        (no change for the standard case of SEAICE_area_max=1)
1319    o some cleaning:
1320      - pkg source files: ensure that all *.F files from each pkg included the
1321        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
1322        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
1323        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
1324        includes;
1325      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
1326      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
1327        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
1328        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
1329      - update option-file CPP_OPTIONS.h of all AD experiments:
1330        * no longer include PACKAGES_CONFIG.h ;
1331        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
1332        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
1333          including ECCO_CPPOPTIONS.h).
1334    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
1335      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
1336        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
1337        not necessary accurate).
1338      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
1339        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
1340        deliberately break compilation (a remainder that it needs to be customized)
1341      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
1342      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
1343      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
1344    o tools/genamke2:
1345      - check for lapack.
1346    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
1347      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
1348        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
1349        from both packages.
1350      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
1351      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
1352      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
1353        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
1354    o pkg/cost : add comments to explain special and/or untested setups.
1355    o pkg/exf:
1356      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
1357        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
1358    o verification/*/code_ad:
1359      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
1360      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
1361      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
1362        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
1363    o pkg/seaice :
1364      - added possibility to change ice strength/PRESS0 relationship to
1365        HEFF, according to the following run time parameters
1366        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
1367        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
1368        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
1369    o pkg/ggl90 :
1370      - added run time flag mxlSurfFlag to include the code that ensure
1371        mixing between first and second level (previously included as a comment)
1372    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
1373      - add test of newly added dumpAdByRec=T option where
1374        we write all records to one file per variable.
1375    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
1376      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
1377        to check that this code is ok with taf and compiles in adjoint.
1378    o pkg/autodiff :
1379      - added run time param dumpAdByRec : ad dump format switch.
1380        If true then write all records to one file per variable.
1381        Else write one file per record (remains the default).
1382      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
1383    o pkg/seaice:
1384     - Added SEAICEuseTILT run time switch : if set to
1385       false then omit the tilt term in seaice dynamics.
1386     - Fix free drift calculation.
1387    o pkg/shelfice:
1388      When initializing SHELFICEDragQuadratic, set default to be
1389      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
1390      but retain option to set it independently
1391      (inconsistenty spotted by Veronique Dansereau)
1392    o eesupp/inc:
1393      - in EEPARAMS.h, add real-type constant for some frequently used simple number
1394         (0,1,2,1/2), with name explicitly referring to RS/RL type.
1395    o model/src:
1396      - move balancing of relaxation terms to new S/R balance_relax.F.
1397    o pkg/autodiff:
1398      re-write active I/O high-level (control) S/R:
1399      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
1400      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
1401      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
1402        MDS_READ/WRITE_FIELD); change loops to multi-threads.
1403      - update and merge active_file_control_slice.flow into active_file_control.flow
1404      - update the calls in lower level S/R (active_file.F, active_file_g.F and
1405        active_file_ad.F) keeping the argument list and function unchanged.
1406      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
1407        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
1408      - new low-level active I/O routines, one for each type (RL/RS), for active var
1409        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
1410        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
1411        right type.
1412    o autodiff and RS=real*4:
1413      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
1414        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
1415      - change argument type of 3-D mask argument to _RS to match type in the call
1416        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
1417    o pkg/thsice:
1418      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
1419      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
1420        fresh-water flux: uniform correction or proportional to local precip.
1421    o pkg/ctrl:
1422      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
1423      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
1424                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
1425      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
1426    
1427    checkpoint63q (2012/07/30)
1428    o pkg/autodiff:
1429      note about monitor and snap-shot of ad-variables:
1430      a) need to apply ADEXCH before monitor or output of ad-vars to include
1431       overlap contributions (was done for adjDump but missing for monitor).
1432      b) since ADEXCH implies adding overlap values to interior array, machine
1433       truncation error is expected when adding an ADEXCH call in the middle of
1434       the time-stepping (although mathematically identical).
1435      modifs:
1436      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
1437        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
1438      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
1439        apply ADEXCH before monitor or snap-shot of ad-variables:
1440           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
1441      - implement new method (copy+adexch) for snap-shot and monitor of main model
1442        ad-vars (initially not used by default -> output unchanged).
1443      - change default (set to 2) to use new method and update few output_adm.txt
1444        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
1445        and both tutorial_tracer_adjsens tests).
1446      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
1447        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
1448    o pkg/ctrl:
1449      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
1450      generic control variables via
1451      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
1452      Only required customization should be S/R ctrl_map_ini_genarr.F
1453      (routine in repository contains example)
1454    o pkg/exf:
1455      - fix and refine checking of surface-relaxation setting when using EXF
1456    o verification (adjoint exp):
1457      - reduce length of simulation by half for experiment global_ocean.cs32x15
1458        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
1459    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
1460      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
1461        of KE that can occur with aggressive optimization
1462      + put quadratic bottom drag calculation in separated loops (only done if
1463        using bottomDragQuadratic)
1464    o model/src: CG2D_NSA
1465      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
1466         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
1467      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
1468         change cg2d residual target to be expressed in Wunits (=> do not normalise
1469         RHS ; this fix global_max Pb with TAF); update output.
1470    o verification/tutorial_tracer_adjsens:
1471       improve parameter consistency (and get rid of warnings):
1472       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1473       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1474       - use staggerTimeStep (for stability) in som81; use default rotation period.
1475    o pkg/exch2:
1476      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1477        reset to 0 = 1 long line in X)
1478    o pkg/mdsio:
1479      - fix reading of dimensions from meta file for large-size domain
1480    o model/src:
1481      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1482      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1483        Cubed-Sphere Exch with CS-corners inside the domain;
1484        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1485        globalArea and to set hasWetCSCorners.
1486      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1487        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1488      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1489        useCDscheme and useCubedSphereExchange).
1490    o pkg/seaice/seaice_growth.F :
1491      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1492        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1493        when the previous code was not correct.
1494      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1495      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1496        that term to QNET (essentially to set the melt/freeze water to 0degC).
1497        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1498    o verification/global_ocean.cs32x15/input.seaice :
1499      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1500      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1501      - update results (output.seaice.txt) accordingly.
1502    o verification/lab_sea/input/data.seaice :
1503      - remove SEAICEheatConsFix, which is now be tested
1504        in global_ocean.cs32x15. The presently coded fix
1505        is only consistent with real fresh water + nlfs.
1506      - update results (output.txt) accordingly.
1507    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1508    o AD_CONFIG.h file:
1509      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1510      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1511        add it explicitly in each fortran src file where it is needed.
1512        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1513        thus introducing potentially wrong dependency; therefore, better to include
1514        it only where it's really needed, and after any other included OPTIONS file
1515        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1516        or ALLOW_TANGENTLINEAR_RUN).
1517    
1518    checkpoint63p (2012/07/06)
1519    o pkg/autodiff:
1520      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1521      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1522        which are now read from new parameter file "data.autodiff" (inAdExact
1523        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1524      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1525      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1526        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1527    o verification/tutorial_tracer_adjsens/
1528      - add extra sub-verification which uses "SOM" advection scheme
1529        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1530          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1531        and in data:
1532          multiDimAdvection=.TRUE.,
1533          tempAdvScheme=81,
1534          saltAdvScheme=81,
1535    o model/src:
1536      - introduce ALLOW_BALANCE_RELAX which allow the removal
1537       of the global mean of relaxation terms by setting
1538       balanceThetaClimRelax and balanceSaltClimRelax
1539      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1540       This case is now treated appropriately in seaice_growth.F
1541    o pkg/seaice:
1542      - do balanceEmPmR and balanceQnet based on the net fluxes
1543        (SItflux) that enter the ocean+ice system rather than QNET
1544        and EMPMR. Works best in real fresh water.
1545      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1546        out of the diagnotics bloc, and stored in global arrays.
1547    
1548    checkpoint63o (2012/06/29)
1549    o vertical mixing schemes:
1550      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1551      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1552        to S/R FIND_RHO_SCALAR
1553      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1554        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1555        affects output (vermix.ggl90) at truncation level.
1556    o testreport:
1557      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1558        (nSx,nSy) for the number of threads (from eedata.mth)
1559    o model/src:
1560      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1561        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1562    o verification/tutorial_tracer_adjsens/
1563      - compile with ALLOW_CG2D_NSA
1564      - run with nonlinFreeSurf=3
1565      - update reference output_adm.txt
1566    o tools/genmake2:
1567      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
1568        refine usePROFILES switching off (only when NetCDF is not available).
1569    o verification (atmospheric set-up):
1570      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
1571    o pkg/profiles : refine profiles and files handling.
1572    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
1573    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
1574      - changes to use model/src/the_main_loop.F rather than the ecco version
1575        in ecco type adjoint runs.
1576    o model/src:
1577      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
1578      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
1579      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
1580    o model/src:
1581      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
1582        update output of test experiment bottom_ctrl_5x5.
1583    o pkg/generic_advdiff:
1584      - implement vertical bi-harmonic diffusion (for now, only for T & S and
1585        only explicitly).
1586    o verification/bottom_ctrl_5x5/
1587      update reference output (results changed quite some time ago,
1588      not sure when; but new reference results look ok in terms of grdchk)
1589    o verification/1D_ocean_ice_column/
1590      For verification purposes, the exact adjoint rather than an approx.
1591      should be used (e.g., to comare against F.D. or TLM).
1592      removed autodiff_inadmode*_ad.F routines in code_ad/
1593      Update results/ accordingly.
1594    o pkg/cal:
1595      - change cal_getdate.F so that output date is function of input time only
1596        (less ambiguous, not mixed up with input iteration number).
1597      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
1598    o pkg/diagnostics:
1599      - implement calendarDumps also for stats-diags
1600      - implement calendarDumps also for snap-shot output (negative freq)
1601      - for now, ignores calendarDumps if non-zero phase-lag.
1602    
1603    checkpoint63n (2012/06/04)
1604    o model/src:
1605      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
1606        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
1607      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
1608        similar to calc_r_star.F); update results of experiment internal_wave and
1609        tutorial_global_oce_in_p (affected @ truncation level).
1610    o pkg/shelfice:
1611      - add parameterisation of advective-diffusive flux into the ice shelf
1612        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
1613      - simply eps3/3a computation
1614    o eesupp:
1615     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
1616       between tiles, just fill-in edges assuming locally periodic subdomain) and
1617       add corresponding exchange subroutines (EXCH0);
1618     - new CG-solver version (_EX0) for disconnected-tiles special case.
1619    o model/src (CG-solvers):
1620     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
1621       (similar final residual output and max-Iter number as with standard version);
1622     - allows to store and use lowest-residual solution (standard & _SR versions);
1623     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
1624     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
1625    o eesup/src:
1626     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
1627       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
1628    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
1629    
1630    checkpoint63m (2012/04/27)
1631    o pkg/shelfice:
1632     - account for partical cells in surface level below ice-shelf for hydrostatic
1633       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
1634    o ad test experiments:
1635     - update and rename to "ad_optfile.local" local AD-optfile specific to a
1636       particular adjoint verification experiment (in verification/*/code_ad/)
1637    o pkg/seaice & pkg/exf:
1638     - Part two of ECCO-CLIVAR code merges.
1639       Completes merge of seaice area relax. code.
1640       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
1641       to be set in EXF_OPTIONS.h since this pkg controls its I/O
1642       (and avoids second CPP option in SEAICE_OPTIONS.h)
1643     - change default value of costIceStart & costIceEnd to a valid date.
1644     - add snowPrecip to HSNOW in seaice_growth
1645    o pkg/ptracers:
1646     - move ptracers summary and setup check into separated S/R ; add a check for
1647       valid PTRACERS_Iter0 value (error+stop or just warning).
1648    o pkg/cal (+ pkg/ecco):
1649     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
1650       as input; and for AD, unless both are not differentiable (e.g., k index)).
1651    o model/src:
1652     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
1653       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
1654       temporary set to usingZCoords value (to be changed to F when using shelfice).
1655     - hydrostatic pressure: implement partial cell near the surface also for
1656       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
1657       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
1658    o pkg/ctrl/ctrl_init.F:
1659     - add a formal parameter to s/r ctrl_init_rec to print
1660       xx_$(ctrl_valiable)_file for easier debugging
1661     - move call of cal_* routines into the if-block where they are really
1662       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
1663       to specify a startdate
1664    o pkg/seaice:
1665     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
1666       global_ocean.cs32x15/code versions).
1667     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
1668       verification experiment global_ocean.cs32x15.seaice and update results.
1669    o pkg/exf:
1670     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
1671       (according to useExfYearlyFields).
1672    o pkg/cal:
1673     - move calendar setting & summary (previously in cal_readparams.F) into new
1674       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
1675       length of the simulation is set (after SET_PARMS call); This is an attempt
1676       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
1677     - For safety: keep a record of pkg/cal parameter settings status
1678               to allow to STOP if one pkg/cal S/R is called too early.
1679     - add a stop in all basic pkg/cal subroutines if called before setting is done.
1680     - modify cal_getdate.F: stop when nothing was returned;
1681       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
1682       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
1683    
1684    checkpoint63l (2012/04/04)
1685    o pkg/bbl:
1686      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
1687        update global_with_exf output.yearly.txt file.
1688    o pkg/cal:
1689      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
1690      - remove 2 unsused and very short (1 line only) functions ;
1691      - remove unsused subroutines from AD-Diff list.
1692    o model/src:
1693      - start to implement clean wait to stop in initialization S/R (config_check.F,
1694         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
1695    o folowing PRINT_MESSAGE changes:
1696      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
1697    o pkg/bbl:
1698      - modification so it can work with z*
1699      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
1700      - global_with_exf/input.yearly verification; changes output.yearly.txt
1701    o eesupp/src:
1702      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
1703        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
1704      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
1705        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
1706      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
1707      - when using MPI, always set usingMPI=T ; set default accordingly and stop
1708        if not consistent.
1709      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
1710        argument is zero (in case called within single-thread section).
1711    o pkg/fizhi:
1712        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
1713        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
1714    o pkg/exch2:
1715      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
1716        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
1717      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
1718        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
1719        with bad ones coming from a not-yet-updated halo.
1720        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
1721    o pkg/frazil:
1722        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
1723        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
1724    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
1725    o verification/lab_sea
1726      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
1727      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
1728      * nTimeSteps 3 -> 4
1729      * changed reference output accordingly
1730    o pkg/ctrl:
1731      * fix ctrl_get_gen for xx_sst, xx_sss
1732    o pkg/fizhi:
1733      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
1734        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
1735      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
1736        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
1737        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
1738    o pkg/gmredi:
1739      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
1740    o pkg/fizhi:
1741      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
1742        (old)aces open64 tuv test.
1743    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
1744    o pkg/mom_vecinv:
1745      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
1746        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
1747        with non-lin free-surf).
1748    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
1749      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
1750      some compilers (gfortran 4.6.0 on MacOS)
1751    o momentum:
1752      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
1753        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
1754        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
1755    
1756    checkpoint63k (2012/03/17)
1757    o model/src:
1758       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
1759         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
1760       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
1761         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
1762    o model/src: solve_*diagonal.F
1763       - replace division with multiplication by inverse (similar to original version)
1764         update output of AD exp. global_ocean.90x40x15.
1765       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
1766         to enable the use of the vectorized & differentiable solve_tridiagonal.F
1767       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
1768         vertical advection (to get solve_tridiagonal tested in AD mode).
1769    o pkg/seaice: ECCO-CLIVAR merge:
1770      1. seaice AREA relaxation
1771         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
1772         * runtime flag: SEAICE_tauAreaObsRelax
1773      2. modified global mean cost imbalance code: CPP option
1774          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
1775    o another iteration on solve_*diagonal.F
1776       Make choices independent of AUTODIFF
1777       Default will be the adjoinable vectorized version.
1778       Alternative choices are:
1779       * non-adjoinable original version with low memory footprint:
1780         #define SOLVE_DIAGONAL_LOWMEMORY
1781       * still adjoinable but does not vectorize (k as inner-most loop):
1782         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
1783    o testreport
1784     - add option to use a home made wrapper around "make"
1785     - remove MITGCM_IEEE env. variable (no longer active)
1786  o pkg/shelfice  o pkg/shelfice
1787   - improve computation of friction velocity for velocity dependent   - improve computation of friction velocity for velocity dependent
1788     exchange coefficients: include velocities into SHELFICEBoundaryLayer     exchange coefficients: include velocities into SHELFICEBoundaryLayer
