4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/bling:
8      - Many small changes intended to clean the code.
9        Unnecessary ADJOINT_SAFEs removed
10        removed BLING_COST.h BLING_CTRL.h bling_cost.F
11        diagnostics added
12    
13    checkpoint66e (2017/03/14)
14    o pkg/exf:
15      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
16        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
17        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
18        avoid any dynamic allocation ;
19      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
20        read-in ; add warning when file is read-in but not used within pkg/exf ;
21        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
22      - update exf_summary.F (print {FLD}RepCycle).
23    o verification/global_with_exf:
24      - switch on exf interpolation in AD test (just like the forward test)
25    o pkg/mom_vecinv:
26      - add storage directives to avoid recomputations within mom_vecinv.F
27        which were generating seg. fault with gfortran -devel
28    o pkg/ctrl, pkg/smooth:
29      - initialize array halos which were generating seg. fault with
30        gfortran -devel in adjoint mode
31    o pkg/exf:
32      - for each input field, enable to specify a field specific repeat-cycle
33        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
34    o verification/lab_sea:
35      - update AD results of primary test and noseaicedyn test after switching
36        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
37        check stays about the same.
38    o pkg/exf:
39      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
40      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
41    o pkg/bling, USE_EXFCO2 code:
42      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
43      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
44    o pkg/exf:
45      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
46      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
47        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
48        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
49      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
50        EXF_INIT_FLD) and update calls in exf_init_varia.F
51      - For now, for backward compatibility, keep a simplified version of S/Rs
52        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
53      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
54        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
55    o tools/genmake2:
56      - replace "bc -l" (only used once) by "expr" (already used).
57    o verification/global_ocean.cs32x15:
58      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
59        Note: exf setting (data.exf) can be compared to other exf secondary exp
60        "seaice" (kept with useCAL=T) which has same time dependent forcing.
61    
62    checkpoint66d (2017/02/13)
63    o pkg/exf:
64      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
65        early on (in packages_boot.F) to stress this change in pkg setting.
66      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
67    o model/src:
68      - move call to ecco_phys to end of time step; this may induce minor
69        cost function changes by shifting time averages by one time step
70        for some variables; this revision resulted in changed adjoint results
71        in MITgcm_contrib/verification_other/global_oce_cs32
72    o pkg/exf:
73      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
74        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
75        e.g. precip, are not available.
76    o pkg/flt:
77      - flt_init_varia.F: use pickupSuff if specified
78      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
79        intermediate, step towards completing pkg/exch2 support within pkg/flt;
80        ifdef DEVEL_FLT_EXCH2 then:
81        - flt_init_fixed.F: comment out stop
82        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
83        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
84        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
85        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
86    o tools/genmake2 & pkg/pkg_depend:
87      - define new type of pkg dependency rule ("=pkg_x"), less strict than
88        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
89        (-pkg_x in packages.conf).
90      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
91      - add "+cal" to dependency list of pkg/ecco (needed to compile).
92      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
93    o utils/matlab:
94      - adding ocean_basin routines for defining basin masks.
95    o pkg/exf:
96      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
97        arguments, allowing to check (and stop) if parameter setting of
98         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
99        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
100        for backward compatibility.
101      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
102        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
103    o pkg/bling (USE_EXFCO2 code):
104      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
105        by adding a call to S/R EXF_GETFFIELD_START.
106    o pkg/exf:
107      - allows to compile without pkg/cal (but disabled by current dependency
108        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
109        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
110        of {FLD}startdate1 & date2 ; consistency check not yet coded.
111    o verification/global_ocean.cs32x15:
112      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
113        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
114    o pkg/exf:
115      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
116        calculations); change FWD experiment global_ocean.cs32x15
117        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
118    o pkg/exf:
119      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
120         {FIELD}startdate to {FIELD}StartTime
121        Note: new name also fit better the content, i.e, a start time in second.
122    o eesupp/src:
123      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
124    o pkg/exf:
125      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
126        to allow to read-in Sensible & Latent Heat flux ;
127      - simplify pkg/exf main options:
128        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
129           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
130           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
131        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
132           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
133        3) improve options documentation in EXF_OPTIONS.h.
134    o pkg/ecco:
135      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
136        ecco_summary.F: add passive tracer cost functions to gencost;
137        m_ptracer and m_boxmean_ptracer
138    o pkg/ctrl:
139      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
140        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
141        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
142        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
143    o model/src:
144      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
145        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
146    o pkg/exf:
147      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
148        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
149    
150    checkpoint66c (2017/01/19)
151    o verification:
152      - add new option "-src" to testreport to only produce source code (*.f),
153        including taf output src code (if using '-adm'/'-tlm' option).
154    o pkg/exf:
155      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
156    o pkg/diagnostics:
157      - add run-time variable diagMdsDir to specify a subdirectory for
158        diagnostic output when mds is being used and mdsioLocalDir is not.
159    o pkg/mnc:
160      - mnc_utils.F: edit stop message
161    o pkg/autodiff:
162      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
163        add HAVE_SYSTEM bracket around system call to mkdir
164    o pkg/profiles:
165      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
166        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
167      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
168        add HAVE_SYSTEM bracket around system call to mkdir
169    o pkg/smooth:
170      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
171      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
172      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
173    o pkg/exf:
174      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
175        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
176        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
177      - summary: skip detailed field report if not used (empty file-name).
178    o tools/xmakedepend:
179      - In case line editor "ed" is missing, switch to "sed" command to clean-up
180        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
181    o pkg/exf:
182      - change definition of "hflux" input file to always include Short-Wave;
183        this is now consistent with hflux computation (if using bulk-formulae)
184        and hflux diagnostic & documentation (in EXF_FIELDS.h).
185    
186    checkpoint66b (2016/12/01)
187    o model & momentum pkgs:
188      - implement fully implicit bottom friction combined with implicit surf.
189        pressure, for now, only in hydrostic formulation:
190        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
191          and run with selectImplicitDrag=2 ;
192        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
193      - partial implicit time-stepping (bot. friction + vert. visc first, then
194        surf. press) corresponding to selectImplicitDrag=1 should be applicable
195        to NH formulation but not available until we solve for surf. pressure
196        increment (instead of full etaN).
197      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
198        with implicit vertical viscosity.
199    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
200      - this is a first version that includes many regularisations that may
201        not all be necessary, to be sorted out,
202      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
203      - change one verification experiment in seaice_itd to use and test new code
204      - seaice_growth: catch a case where the argument of log can be zero
205        or smaller (important for code stability)
206    o model/src:
207      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
208        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
209        similar A.X'=Y' system (with same matrix A) in subsequent calls;
210        switch based on errCode (In/Out) argument value; in calling routines,
211        initialise errCode before first call.
212    
213    checkpoint66a (2016/10/18)
214    o pkg/bling:
215      - BLING package now loads in atmospheric pCO2 file using exf package routines
216        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
217    o model/src & pkg/ptracers:
218      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
219        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
220        implicitDiffusion (respectively) are used (even without momImplVertAdv
221        or temp,salt,PTRACERS_ImplVertAdv).
222    o model/src & generic_advdiff:
223      - add parenthesis in main diagonal calculation of implicit vertical
224        diffusion matrix (impldiff.F & gad_implicit_r.F).
225        This affects results at machine truncation level; update output of many
226        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
227    o pkg/mom_commom & generic_advdiff:
228      - add deep atmosphere and anelastic scaling factor in implicit vertical
229        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
230    o model/src:
231      - remove few unnecessary temp array copies in solve_tridiagonal.F
232        & solve_pentadiagonal.F
233    
234    checkpoint65z (2016/09/28)
235    o pkg/seaice: fix multithreading for seaice_fgmres.F
236      - remove unecessary variables from common blocks
237      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
238        basis, that are stored in commom blocks (including integer variable i1)
239      - clean up code a little by removing commented lines that refer to
240        original code
241      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
242    o MITgcm manual:
243      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
244        preliminary documentation for generic controls (8.3; ctrl.tex),
245        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
246        ecco_costfunction.tex
247    o pkg/ecco:
248      - update and cleanup list of CCP options
249      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
250        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
251      - add checks that retired run-time options are not used, and in relation
252        to gencost_mask and gencost_errfile
253      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
254        gencost_nrecperiod
255      - fix m_eta computation for virtual salt flux case
256      - add m_horflux_vol case (selected via gencost_barfile) that computes
257        transports via cost_gencost_boxmean (gencost_flag=-3)
258      - use gencost_flag more systematically (i.e., avoid using gencost_name)
259        for code switches (aside from physical variable selection)
260    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
261      attempt appears to be a bit of a hack and my need some repair down the road
262    o pkg/exf:
263      - interpolation near South Pole: fix criteria on input field latitude.
264    o pkg/icefront & pkg/exf:
265      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
266        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
267    o pkg/exf:
268      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
269        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
270        (add suffix "_out" instead of a prefix); keep same record number as in
271        input file but always write record 1 first (to avoid a STOP in I/O S/R).
272        Change output file content by writing interpolated field before applying
273        land-sea mask (helpful for debug).
274      - 2 compon. vector interpolation with rotation: apply scaling factor on
275        each compon. (Eastward and Northward) just before rotation.
276    o pkg/bling:
277      - Cleaned package. Removed not needed code and comments.
278      - adjoint example now works
279        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
280    o pkg/ptracers:
281      - add Bruno Deremble's code to complete the linear surface correction
282        for tracer conservation;
283      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
284    
285    checkpoint65y (2016/07/29)
286    o pkg/debug (stats):
287      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
288        proc/thread mapping);
289      - fix Min & Max for case where 1 thread has only empty tiles;
290      - use RL variable to count number of wet grid points (with big domain,
291        can be too large to fit into integer*4).
292    o pkg/monitor:
293      - use RL variable to count number of wet grid points (but used only for del2)
294      - add new routine to compute Advective CFL within tracer time-stepping with
295        writing delayed until next monitor output.
296    o pkg/obcs:
297      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
298    o pkg/cal:
299      - calandar-dump: treat case myTime < timePhase in the same way as in
300        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
301    o pkg/dic & seaice:
302      - fix compilation of ocean component for coupled atm+ocn model with
303        seaice dynamics & dic.
304    
305    checkpoint65x (2016/06/11)
306    o add a license text file in main MITgcm tree.
307    o added pkg/bling:
308      - intermediate complexity biogeochemical model
309      - see bling_description.txt for details
310      - verification experiment is global_oce_biogeo_bling (for now, in
311        Contrib/verification_other/); tested daily on baudelaire with gfortran.
312      - add entry point in pkg/gchem for new pkg "bling".
313    o pkg/seaice: fix tensile stength computation
314      - replace global field tensileStrength by tensileStrFac
315      - tensileStrFac can be computed once in S/R seaice_init_varia
316      - fortunately that does not affect any verification results
317    
318    checkpoint65w (2016/05/12)
319    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
320         with ECCO_CTRL_DEPRECATED defined
321    o verification/global_ocean.cs32x15:
322      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
323        with "selectNHfreeSurf=1".
324    o model/src (non-hydrostatic free-surface):
325      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
326        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
327      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
328        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
329        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
330        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
331      - Update output (changes at machine truncation level) of verification exp:
332        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
333        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
334    o pkg/seaice: ITD code
335      - fix picking up from a single category model by initialising
336        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
337      - split a long warning message in seaice_check_pickup.F into two lines,
338        because NEC SX-ACE cannot deal with the long line.
339    o model/src:
340      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
341    o pkg/seaice:
342      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
343    o pkg/seaice:
344      - add basal stress as parameterisation for grounding ice
345        following Lemieux et al. (2015)
346      - turn on by setting new parameter SEAICEbasalDragK2 to a value
347        larger than 0. Lemieux et al. (2015) recommend 15.
348      - The adjoint complains with extra recomputations so there is also a
349        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
350        order to postpone the problem
351      - compile the new code in lab_sea
352    o verification/halfpipe_streamice:
353      - update both TAF and OpenAD adm output (machine truncation differences)
354    
355    checkpoint65v (2016/04/08)
356    o verification/advect_xz:
357      - increase overlap size from 3 to 4 and add new secondary test for PQM
358        advection scheme (with mono & wino limiter).
359      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
360    o model/src:
361      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
362        added phi0Ref) to set vertical axis origin and phiRef origin;
363        keep Ro_SeaLevel for backward compatibility (with a warning).
364       According to coordinate and fluid type:
365        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
366        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
367        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
368        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
369      - remove Ro_SeaLevel from ATM experiment parameter files;
370      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
371        complement; update output.txt (changes at machine truncation level).
372    o pkg/seaice/seaice_evp.F
373      - simplify computation of deltaZ and zetaZ to simple averaging following
374        Bouillon et al. (2013). This removes a lot of code, but also changes
375        verification experiment lab_sea.hb87 -> updated
376    
377    checkpoint65u (2016/03/14)
378    o pkg/generic_advdiff:
379      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
380        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
381        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
382        testing and not for actual use.
383    o model/src:
384      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
385        origin r = rF(1);
386      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
387        in EOS for height coordinate: enable to include NH Pressure or to use
388        more accurate pressure vertical profile; options not linked to EOS type
389        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
390      - start to implement variable gravity (along vertical): for now, only with
391        z-coords (not even z*).
392      - add Ideal Gas equation of state for height coordinate.
393      - update OpenAD output (affected at machine truncation level) of exp:
394        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
395    o pkg/exf:
396      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
397        of exf interpolation (before any rescaling, rotation or interpolation
398        to velocity point) for each field that gets loaded from file. This option
399        identically mimics the input file organization (e.g. record numbers in year
400        by year input files) besides the change in horizontal grid.
401      - add rotateStressOnAgrid run-time switch so that wind stress fields
402        can be provided on the A-grid in zonal/meridional direction and
403        rotated on the fly. This only applies to the case when the exf
404        interpolation is off and rotateStressOnAgrid is false by default.
405    o model/src:
406      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
407        it's also used with pkg/atm_phys) and add few more parameters (but still
408        inactive, src code yet to come)
409    
410    checkpoint65t (2016/02/10)
411    o pkg/atm_phys:
412      - from Ruth Geen: add optical depth dependence on CO2 concentration.
413    o model/src:
414      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
415        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
416        Update output of exp. deep_anelastic (changes at truncation level).
417    o tools:
418      - add a hack in "remove_comments_sed" (used only with TAF) for recent
419        version of OpenMPI (shipped with FC.23): comment out the new header
420        file "mpif-sizeof.h" which causes problems to TAF.
421    o pkg/seaice:
422      - change the termination criterion so that maxits (SEAICElinearIterMax)
423        has an effect
424      - unify iteration parameters for implicit solvers (JFNK and Picard)
425        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
426        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
427        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
428        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
429        SEAICEnonLinTol     replaces JFNKgamma_nonlin
430      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
431      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
432        use with SEAICEuseKrylov
433    o pkg/seaice/seaice_lsr.F
434        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
435        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
436        an effect.
437    o pkg/seaice: add two new parameters
438      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
439        parameter is not in any namelist)
440      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
441        a preconditioner for the non-linear Newton iteration of the JFNK
442        solver
443    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
444      affects some experiments at truncation level:
445      - global_ocean.cs32x15.icedyn (11 digits),
446      - global_ocean.cs32x15.seaice (11 digits),
447      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
448      - also update global_ocean.cs32x15 adjoint and tangent-linear results
449    o pkg/salt_plume & pkg/thsice:
450      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
451        connect salt_plume flux to ATM-OCN coupling pkgs interface:
452       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
453         export to coupler interface) even without compiling pkg/salt_plume ;
454       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
455         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
456    o pkg/dic:
457      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
458        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
459        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
460      - move also update with values from ATM-OCN Coupler in the same new S/R
461        (previously done in ocn_apply_import.F).
462    o tools/adjoint_options:
463      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
464        has been changed on Jan 14, 2016.
465    o pkg/ggl90:
466      - add alternative discretisation of vertical shear (off by default), to
467        compute the mean (@ grid-cell center) of vertical shear compon instead of
468        vertical shear of mean flow (@ grid-cell center).
469      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
470        results on adjacent faces of cubed-sphere grids; this fix the restart.
471    o pkg/atm_compon_interf:
472      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
473        pass last value, stored directly before export to CPL ;
474        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
475      - remove atmSLPr from pickup files (no longer needed for restart)
476    
477    checkpoint65s (2016/01/13)
478    o eesupp & genmake2:
479       - first check for Function ETIME and, if it fails, then check for subroutine
480         ETIME and consistent output; use the appropriate version in timers.F
481    o model/src:
482      - to check restart test, add option to apply EXCH to U,V earlier, just before
483        integr_continuity; turned off by default.
484    o pkg/dic:
485      - remove CPP option USE_ATMOSCO2 (not needed)
486    o tools/tst_2+2:
487      - try to ignore difference between +0 and -0 in binary file, causing test
488        to fail for no good reason.
489    o eesupp & genmake2:
490      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
491        but also check (in genmake2) that test runs and returns meaningful results.
492    o coupler pkgs:
493      Finish implementation of optionally-exchanged variable switches (started on
494       Nov 12) with addition of few more exchanged fields, including 2-way exchange
495       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
496       advection in OCN component; this requires sequential coupling.
497      coupler (pkg/atm_ocn_coupler):
498      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
499        routines (useful for debug).
500      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
501         flux, DIC fields) if corresponding switch is ON.
502      - add option to export RunOff to OCN (to use for DIC river input)
503      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
504      components (pkg/atm_ & ocn_compon_interf):
505      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
506        optionally exchanged fields; add a check & stop in cpl_readparms.F.
507        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
508        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
509      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
510        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
511      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
512      - hold in common block coupler optionally-exchanged variable switch
513        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
514      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
515        this is intended to replace the OCN cplFldtave.* output files (not updated
516        to contain new additional exchanged fields).
517    o pkg/dic:
518      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
519    o pkg/thsice:
520      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
521        and writing of thsice pickup files.
522    o pkg/atm_compon_interf:
523      - move all field individual export-call out of cpl_export_import_data.F
524        into new S/R ATM_EXPORT_FIELDS
525    o pkg/atm_compon_interf:
526      - store state variables (for now, only thSIce fields) just before beeing
527        exported (in cpl_export_import_data.F, like on ocean side) instead of from
528        atm_store_my_data.F like all exported fluxes.
529      - new version of pickup_cpl: write field names into meta file and read meta
530        file to find field postion in pickup. Also only write/read fields meeded for
531        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
532    o pkg/dic:
533      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
534    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
535        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
536        value can be from domain [0,1] to average between the two methods
537    o pkg/atm_phys:
538      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
539        hold fixed in time).
540    
541    checkpoint65r (2015/12/21)
542    o pkg/seaice:
543        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
544        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
545    o pkg/seaice:
546      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
547        when SEAICEscaleSurfStress=.TRUE.,
548      - apply areaW and areaS in S/R seaice_calc_lhs
549    o pkg/atm_phys:
550      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
551        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
552        for individual contribution (convection, LSC cond, radiation)
553      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
554        information); activated with: solar_exponent=0. and wv_exponent=-1.
555    o pkg/ggl90:
556      - within IDEMIX add upper limit for horizontal group velocity to
557        avoid instability problems in the explicit horizontal diffusion term for
558        long time steps or high resolution
559    o pkg/diagnostics:
560      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
561        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
562    o testreport:
563      - remove "-v" (verbose option) in default mpirun command.
564    o pkg/seaice/seaice_growth:
565      - catch potential division by zero in ITD code, does not change
566        verification results
567    o pkg/ecco:
568      - retire old codes to the Attic. The calls to retired functions are
569        left in a commented form in case they ever need to be re-activated.
570      - ecco_check.F: issue warning if any old CPP option is
571        defined that corresponds to retired codes -- then stop.
572    o pkg/atm_compon_interf:
573      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
574        coupler: use last time-step value instead of average over cplSendFrq_iter
575        time-step, similar to what is done for seaIceMass.
576        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
577    o eesupp & genmake2:
578      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
579        <= remove until a fix is found for some ifort version on ia32 machine.
580    o pkg/seaice/seaice_evp:
581      - refine residual computation
582    
583    checkpoint65q (2015/11/18)
584    o pkg/seaice/seaice_evp:
585      - fix residual computations so that they no longer affect the actual
586        simulation code
587      - fix seaice_readparams to be able to actually set new parameters
588        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
589    o model/src:
590      - fix wrong truncation (single prec) from "FLOAT" function in expressions
591        like: deltaT*FLOAT(myIter) when myIter is large:
592         a) replaced by DFLOAT (if not seen by TAF);
593         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
594    o pkg/aim_v23:
595      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
596        when pickupSuff is set ; do write rolling pickups + at the end of the run.
597    o pkg/atm_ocn_coupler + ocn_compon_interf:
598      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
599        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
600        add corresponding call in DO_OCEANIC_PHYS.
601    o coupler pkgs:
602      Start a new way to set-up optionally-exchanged variables (previously, only
603       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
604       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
605       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
606       compononent param default can be set accordingly).
607      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
608       but rather applies to a group a fields (going both ways like for DIC)
609       and corresponds to an option of coupling config.
610      coupler (pkg/atm_ocn_coupler):
611      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
612        and read namelist directly (without eessup S/R calls) instead of
613        in the very un-flexible old way, 1 param per line, in fixed order;
614      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
615        cleanly in CPL_CHECK_CPLCONFIG
616      - add new coupling-exchange selectors (some not yet active) including
617        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
618                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
619      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
620        component ; called directly from coupler.F, after comp. registrations;
621      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
622         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
623          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
624      components (pkg/atm_ & ocn_compon_interf):
625      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
626        CPP header file in all pkg source files.
627      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
628        ATM/OCN_CHECK_CPLCONFIG;
629      - add error-counter to track errors (e.g., in "data.cpl") and to stop
630        cleanly in ATM/OCN_CHECK_CPLCONFIG;
631      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
632        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
633        before PACKAGES_READPARMS;
634      verification/cpl_aim+ocn/:
635      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
636        "data.cpl" for coupler (in input_cpl).
637    o eesupp/inc:
638      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
639        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
640        to always cumulate tile local-sum in the same order (still uses
641        MPI_Allreduce like standard code).
642      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
643        that are now identical to standard version (in eesupp/inc).
644    o pkg/shelfice:
645      - add SHELFICETransCoeffTFile for initializing spatially varying
646        heat and salt transfer coefficients
647    o pkg/atm_compon_interf & ocn_compon_interf:
648      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
649        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
650      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
651    o pkg/atm_ocn_coupler:
652      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
653    o pkg/rbcs:
654      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
655        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
656      - add a short report (to STDOUT) about RBCS-mask settings.
657    
658    checkpoint65p (2015/10/23)
659    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
660        there is no adjoint test for EVP, we don't know what it does to the adjoint
661        solution, but at least there are no more recomputation warnings left
662    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
663        a chance of giving the same results as a fully converged VP (JFNK) solver
664    o tools/adjoint_options/adjoint_diva:
665      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
666    o pkg/streamice:
667      - spotted bug in streamice_driving_stress using dyG where should have been dxG
668    o pkg/exf:
669      - remove STOP statement that prevented to use wind or (wind-)stress
670        interpolation for constant-in-time forcing fields (wind/stress period = 0).
671    o pkg/seaice:
672      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
673        5 additionals 2D fields and 6 new store directives
674      - change logic in seaice_readparms.F: EVP code can now be turned on in
675        various ways, setting SEAICE_deltaTev is no longer required,
676        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
677        or SEAICEaEVPcoeff
678    o pkg/shelfice/shelfice_thermodynamics.F
679      - redefining uLoc/vLoc to u/v, instead of 2u/v
680    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
681      - this is an intermediate state of a truely converging EVP that has
682        the potential of outperforming implicit VP methods, I do not recommend
683        using it yet.
684      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
685        and all parameters are hardwired
686      - for convergence it still requires very smooth regularisations, that means,
687        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
688        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
689        specific averaging appears to be required, still subject to tuning
690      - still needs cleaning and I need to turn parameter into runtime parameters
691      - add code to compute and print residuals of iteration, compile with
692        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
693    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
694      that entered with r1.54 on Sep04, 2015, -> update results
695    
696    checkpoint65o (2015/09/14)
697    o pkg/mom_vecinv & mom_common:
698      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
699        called from there.
700      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
701        allows to use Vector-Invariant form in deep atmos and anelastic formulation
702    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
703      and Koenig-Beatty+Holland (2012)
704      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
705      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
706      - requires an extra input argument for S/R seaice_calc_viscosities
707      - tensileStrength's depth dependence is different from Itkin et al. (2015)
708        (to be changed and played with, for now exponential)
709    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
710      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
711        by AREA according to Connelly et al. (2004), JPO.
712      - For EVP and the LSR solver, the implicit part of the drag term is
713        the only non-zero term in the denominator when there is no ice (which
714        prevented running the model with zero ice-ocean drag). If
715        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
716        (or zero main diagonals BU/BV) which need to be caught. A practical
717        consequence is that for open water, the momentum equation reduce
718        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
719        they happen to be zero, often leading to a non-zero solution over
720        open water.
721    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
722        efficient EVP method.
723      - introduce area-weighted averages for e12 (analogously to
724        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
725        remain, but also changing the order of terms in the previous average
726        changed the results as much) -> update experiment
727      - add SEAICE_DELTA_SMOOTHREG code
728      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
729        TEM-code
730      - adjust loop bounds so that only required fields are computed
731      - add new averaging code for zetaZ/deltaZ (again similar to
732        seaice_calc_viscosities.F), inactive by default for now (will change
733        results again), but will replace old code eventually
734    o eesupp/src:
735      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
736        to always cumulate tile local-sum in the same order
737        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
738        Still uses MPI_Allreduce (like standard code) but on array of tiles
739        and should be faster than GLOBAL_SUM_SEND_RECV code.
740      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
741        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
742      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
743         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
744         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
745         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
746         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
747    
748    checkpoint65n (2015/07/29)
749    o pkg/thsice:
750      - add a warning when used with pkg/aim but without updating SST
751        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
752    o pkg/offline:
753      - change where Offline-Fields are loaded, from load_fields_driver.F to
754        directly within FORWARD_STEP, just after updating iter number and time;
755      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
756        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
757       These changes allow:
758        a) to recover exactly on-line results using deltaToffline=deltaTClock,
759        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
760        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
761        time-step, both with GM & KPP files and with recomputing these fields;
762        b) no needs to switch on staggerTimeStep anymore;
763        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
764      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
765    o pkg/offline:
766      - change (rarely used) offset-iteration parameter to an offset time (in s):
767        can easily recover previous offset-iter effect by setting offset-time
768        (offlineTimeOffset) to offset-iter x deltaToffline;
769      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
770        in KPP as part of surface buoyancy forcing) in offline run.
771      - fix ptracers KPP non-local term in the case where KPP is re-computed.
772    o OpenAD
773      - Adding preliminary ggl90 test to OpenAD verification.
774        Config. with ggl90 currently diverges after 64 time steps
775        so will need more work to become more stable
776      - Adding preliminary kpp test to OpenAD verification.
777        required small tweakes in kpp_routines.F
778      - Merge and update from Krishna Narayanan's contrib area:
779        * Add one variable for preliminary OpenAD DIVA
780        * Add replacement time-stepping for OpenAD DIVA
781        * genmake2 flag -diva (but only for OpenAD; preliminary)
782        * required modifs for OAD_support
783        successful preliminary test for tutorial_global_oce_biogeo/
784    o pkg/seaice:
785      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
786      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
787        delta with a smooth function in s/r seaice_calc_viscosity
788        (no effect on EVP)
789      - rename local suffix "sqr" into "sq" for more consistent variable names
790    o pkg/seaice:
791        add new parameter SEAICE_deltaMin that is used ***only***
792        for regularizing Delta (and nothing else, like the parameter
793        which is also used for all sorts of things SEAICE_EPS).
794        Defaults to SEAICE_EPS for backward compatibility only.
795    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
796        the wrong key by inialising it before use -> fixes a recomputation
797        problem but does not fix the gradient
798    o pkg/layers:
799      - move resetting of flux arrays to outside the iLa loop
800        (this caused layers_diapycnal to not work with more than one layer coord.)
801      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
802    o pkg/layers:
803      - remove from common block 3D layers fields (used to diagnose transport
804        in tracer coords) and declare them as local arrays in layers_calc.F
805    o pkg/seaice:
806      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
807        in lab_sea forward experiment (changes results -> updated)
808      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
809    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
810       computations; for SEAICE_VECTORIZE_LSR
811      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
812        sweep to the outside,
813      - remove store directives and add "CADJ loop sequential" directives
814        in analogy to model/src/solve_tridiagonal.F
815      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
816        boundaries to yield more readable code. This has also the charming side
817        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
818        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
819        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
820        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
821        an additional option)
822       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
823       but the adjoint gradients (which are affected by this change) still explode.
824    o coupler (atm & ocn _compon_interf):
825      - avoid using Exch2 IO mapping if not suitable.
826    
827    checkpoint65m (2015/06/15)
828    o pkg/layers:
829      - clean-up old parameters setting (from Sep 2012):
830        + remove old parameters setting from common block (declared locally);
831        + stop if any old parameter is mixed with new parameters;
832        + check for valid or consistent parameter setting (e.g., layers_name)
833      - check that layers_bounds for Pot.Density are in the right range;
834        this is supposed to catch un-updated setting after recently shifting
835        potential density field "prho" by -1000 (now in "sigma" scale).
836    o pkg/layers:
837      - Added missing call to layers_fill for keeping track of tottend in
838        pkg/diagnostics/diagnostics_fill_state.F
839    o pkg/layers:
840      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
841        of diapycnal fluxes
842    o pkg/layers:
843      - reverted changes to interpolation to previous treatment; there
844        was never actually a problem
845    o pkg/layers:
846      - fix interpolation of layers tracers in the presence of partial cells
847      - add lots of new functionality to compute water mass transformation
848        (enabled by CPP flag LAYERS_THERMODYNAMICS)
849      - add new calls from main code (diags_oceanic_surf_flux.F,
850        thermodynamics.F, impldiff.F) and gad to save the necessary fields
851        for layers_thermodynamics calculations
852    o pkg/ptracers:
853      - add capability of stepping a passive tracer forward without advection
854        by setting PTRACERS_advScheme to 0.
855    o pkg/diagnostics:
856      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
857    o pkg/layers:
858      - shift potential density field "prho" by -1000 for density layer averaging so
859        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
860        Note that density bin boundaries (layers_bounds in data.layers) have
861        to be set accordingly (i.e., shifted, in sigma scale).
862    o pkg/layers:
863      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
864      - fix calculation of layer non-weighted velocity and layer probability
865      - add diagnostics for pot.density used for layer averaging
866    o pkg/seaice:
867      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
868        positiveness, modify a few comments and improve variable names,
869      - the changed computation of deltaC affects most seaice-related
870        experiments at the truncation level.
871        seaice_itd.thermo is affected by far the most, with
872        only 7 digits of agreement remaining; update experiments.
873    
874    checkpoint65l (2015/05/04)
875    o pkg/shelfice:
876      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
877        factor drKp1 to zero where it is negative (ie. do not use
878        SHELFICEBoundaryLayer if hFacC>1)
879      - the same for factor drLoc in shelfice_forcing.F
880    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
881        with modules in ptracers, when using testreport option "-small_f"
882    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
883      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
884    o verification/testreport
885      - add new option -small_f
886        with this option testreport first makes the target small_f (*.f files)
887        before running make (all). This is useful for explicit inlining when
888        all sources need to be full available.
889    o pkg/exf/exf_interp.F:
890        remove previous changes related to reverse (decreasing) input grids latitude
891    
892    checkpoint65k (2015/04/01)
893    o pkg/ecco:
894        fix missing cosphi initialization; use eccoiter in place of optimcycle;
895        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
896        instead of active read/write
897    o pkg/ctrl:
898        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
899        instead of active read/write.
900    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
901        return if .NOT.useAUTODIFF
902    o pkg/seaice: add CPP brackets (cost function related).
903    o model/src:
904        add useAUTODIFF run time switch.
905    o pkg/exf/exf_interp.F:
906        add code to allow input grids with latitude starting in the north (i.e. when
907        j=1 corresponds to northern edge of field); modify global_with_exf to test
908        this feature.
909    o verification/testreport:
910      - replace "grep -A3" with POSIX conformal sed command, because there are
911        implementations of grep that cannot do contextual searches
912      - replace "cat -n" by "nl" (two occurrences), because not all implementations
913        of "cat" have the option "-n"
914    o model/src:
915        add new file gsw_teos10.F that contains 3 functions, more or less a copy
916        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
917        convert from conservative to potential temperature. For now they are not
918        called anywhere.
919    o pkg/ggl90: make "useIDEMIX" useful
920      - re-organize code in s/r ggl90_calc a little to move computations that
921        are different for idemix into separate loops (changes verification
922        experiment idemix at truncation level, 12 digits remain -> updated)
923      - requires 2 new 2D fields KappaM, verticalShear
924      - make hFacI and recip_hFacI local 3D variables that are passed to
925        s/r ggl90_idemix
926      - fix and improve some comments
927    
928    checkpoint65j (2015/02/25)
929    o pkg/openad
930      - synchronize seawater.F with version in model/src: replace routine
931        body of sw_temp by calling sw_ptmp and fix/add a few comments.
932    o pkg/mnc:
933      - change default value of pickup_read/write_mnc params to FALSE
934        (since few features are missing in reading MNC pickup files).
935    o model/src:
936      - change default (background) vertical diffusivity for salt to be the
937        temperature (background) vertical diffusivity.
938      - change background vertical diffusivity in vertical mixing pkgs ggl90,
939        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
940        This makes ptracers default diffusivity (that uses salt diffKr) more
941        consistent with vertical mixing schemes.
942    o verification/testreport:
943      - fix typo in "-pcls" option ;
944      - put temp files in /tmp (instead of in local dir)
945      - add option "-ncad" to use genmake2 new option "-nocat4ad"
946      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
947    o pkg/ggl90 (idemix code):
948      - apply few fixes ; add some missing "_d 0" ; update output of exp.
949        global_ocean.90x40x15.idemix
950    o OpenAD
951      - enable active file I/O and begin removal of work-around code
952        for OpenAD for handling control variables (memory vs. active files)
953      - new CPP options file OPENAD_OPTIONS.h
954      - revert to genarr2d gradient check for hs94.1x64x5
955      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
956      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
957    o tools/genmake2:
958      - add option for an alternative Makefile (from Martin) where multiple
959        source files are sent to TAF (instead of all in one file).
960    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
961      - code provided by Carsten Eden as an extension of ggl90
962      - so far the code is turned on within ggl90 by setting a CPP-flag at
963        compile time; a runtime flag implementation is not yet complete
964      - tested in new verification experiment global_ocean.90x40x15.idemix
965    o verification:
966      - reduce length of the AD test run by half for experiments
967        global_ocean.cs32x15 (std + thsice) and isomip
968      - enable active file I/O for OpenAD, adjust verifications accordingly
969      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
970    o verification/testreport:
971      - fix two non-POSIX sed statements so that there are no error messages
972        on Mac OS X
973      - replace hostname -s with hostname | sed 's/\..*$//'
974    o model/src/seawater.F:
975      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
976        (following the matlab code), which would have avoided the bug caught
977        by Matt (see below) in the first place
978    o pkg/shelfice:
979      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
980        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
981      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
982        ice-shelf case (i.e., within surface level).
983      - add config summary in shelfice_check.F
984      - remove global variable recip_SHELFICElatentHeat and replace by a local
985        variable recip_latentHeat
986      - introduce diagnostics for friction velocity uStar (in case of
987        SHELFICEuseGammaFrict)
988      - change verification experiment isomip.htd:
989        + start from pickup (as input_ad at nIter0=8640)
990        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
991        + test SHELFICEuseGammaFrict = .TRUE.
992        + test SHELFICEadvDiffHeatFlux = .TRUE.
993    o model/src:
994      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
995        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
996        update output of experiments global_with_exf.yearly and isomip (all 6).
997    o pkg/shelfice:
998      - change setting of kTopC to also be zero where there is no ice-shelf.
999      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1000        ice-shelf is.
1001      - first attempt to get RealFreshWaterFlux effects: for now, only without
1002        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1003    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1004      for thermodynamic calculations
1005      - because of divisions of the type 7/7 not exactly equal to 1, this change
1006        affects results of some verification experiments by up to 4 digits:
1007        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1008        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1009        adjoint: lab_sea, lab_sea.noseaicedyn
1010        -> updated
1011    
1012    checkpoint65i (2015/01/23)
1013    o model/src:
1014      - change units of frictionHeating field from W to W/m^2
1015      - fix bug in frictional heating from stratospheric drag in
1016        S/R ATM_PHYS_TENDENCY_APPLY_V
1017      - with synchronous time-stepping: move resetting to zero of frictionHeating
1018        field from load_fields_driver.F to thermodynamics.F ;
1019      - add diagnostics for frictional heating.
1020    o model/src & gmredi K3D:
1021      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1022      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1023      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1024        and name in pickup file).
1025      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1026    o model/src:
1027      - move (from ini_forcing.F) initialisation of all arrays in header file
1028        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1029        (since Nov 2012) with option selectAddFluid=1.
1030    o pkg/shelfice:
1031      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1032      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1033    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1034    o pkg/seaice: two new runtime parameters:
1035      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1036        long overdue
1037      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1038        parameterization of tensil stress for fast ice (does not do anything yet)
1039    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1040        for LSR: move checking overlaps out of JFNK-if-block
1041    o pkg/atm_phys:
1042      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1043        new S/R ATM_PHYS_DYN2PHYS.
1044      - fix level height for Linear Free-Surf case (to be consistent with
1045        fixed-in-time pressure levels).
1046    o pkg/mom_common (bottomdrag):
1047      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1048        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1049        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1050    o pkg/shelfice (u/v_drag):
1051      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1052      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1053        (now similar to shelfice_u_drag.F)
1054      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1055        from mom_vecinv.F (similar to mom_fluxform calls).
1056    o pkg/mom_common (bottomdrag):
1057      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1058      - add options for alternative discretisation of velocity norm in quadratic
1059        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1060        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1061        improves when averaging only the other component (e.g. vVel for U bottom
1062        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1063      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1064        friction (no-slip BC) thus getting the true distance from the bottom;
1065        off by default since this also reduces model stability (explicit bottom
1066        friction). Changes produce different machine truncation with linear-drag
1067        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1068        front_relax (bvp & mxl, 10 & 11 digits).
1069    o model/src & mom pkgs:
1070      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1071        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1072      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1073        just copy level Nr value to level Nr+1.
1074    o doc:
1075      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1076    o pkg/shelfice:
1077      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1078        SHELFICE.h: move array shelficemass to init_varia, initialise
1079        from array shelficemassinit, which is set in init_fixed and
1080        has option to be set from file; introduce array
1081        shelficeMassDynTend array, set thru file in init_fixed
1082      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1083        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1084        pkg/streamice
1085      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1086        SHELFICEMassStepping = .true.
1087      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1088    
1089    checkpoint65h (2014/12/17)
1090    o verification/global_ocean.90x40x15, global_ocean_ebm:
1091      - update to generic controls.
1092    o pkg/ctrl:
1093      - ctrl_map_ini_genarr.F: test for igen>0
1094      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1095      - move gentim2d part of ctrl_map_ini_genarr.F to
1096        new separate routine : ctrl_map_ini_gentim2d.F
1097      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1098        add time variable weights and cyclic controls (time mean,
1099        seasonal cycle, etc) capabilities to gentim2d
1100    o pkg/ecco:
1101      - move reading of error, conversion to weights from
1102        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1103    o global_oce_llc90, cs32:
1104      - activte sbo.
1105      - CTRL_SIZE.h : add maxCtrlProc.
1106      - activate the new genctrl capabilities.
1107      - update following reorganization of global_oce_input_fields.tar.gz  
1108    o pkg/ctrl/ctrl_ad_diff.list:
1109      - add missing ctrl_init_rec.f
1110    o tools/OAD_support/keepOriginal:
1111      - add ctrl_init_rec.F
1112    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1113      - avoid recomputations of xx_gentim2d_dummy.
1114    o momentum diagnostics:
1115      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1116        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1117    o pkg/seaice/seaice_lsr.F:
1118      - fix computation of BU/BV, make sure they are non-zero, only necessary
1119        for cubed sphere exchanges and SEAICE_OLx/y>0.
1120        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1121    o verification/global_ocean.cs32x15/input.seaice
1122      - add test for strong implicit coupling and restricted addtive Schwarz
1123        methods for LSR
1124      - update results/output.seaice.txt
1125    o verification/tutorial_global_oce_biogeo:
1126      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1127        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1128        update output_adm,_oadm,_tlm.txt
1129    o pkg/dic:
1130      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1131      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1132        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1133    o verification/tutorial_global_oce_biogeo:
1134      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1135        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1136        update output_adm,_oadm,_tlm.txt
1137    o eesupp/src:
1138      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1139        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1140    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1141      LSR (following Hutchings et al. 2004)
1142      - introduce zetaZ as a global variable (requires adjustments in
1143        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1144        in seaice_calc_viscosities.F
1145      - new flag SEAICEuseStrImpCpl (default off)
1146      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1147        momentum equations
1148      - JFNK-solver (preconditioner) adjusted to allow using this method
1149        (where it does not have any positive effect)
1150    o pkg/seaice
1151      - add overlap for restrictive additive Schwartz method also to LSR, but
1152        turn it off by default (because it only seems to work for non-cubed
1153        sphere/llc topologies)
1154    o pkg/autodiff
1155      - add extra exchanges in addummy_in_steppging also for mnc output
1156    o pkg/seaice:
1157      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1158        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1159    o pkg/obcs:
1160      - add option to specify domain-connected piece Id along OB though files
1161        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1162      - modify obcs_diag_balance.F to process each connected-part separately;
1163        exclude OB where Id = 0 but keep the full divergence there (-> constant
1164        Psi along this portion of OB and all inflow derived from grad(Phi))
1165      - add example of OB-conect files in verification/so_box_biogeo/input.
1166    o pkg/diagnostics:
1167      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1168      a) use non zero matrix element across OB and solve for Phi 1 grid point
1169         outside OB (i.e, where tracer OBCS are applied).
1170      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1171         velocity across OB, spread it uniformly along the OB in the RHS.
1172    
1173    checkpoint65g (2014/11/19)
1174    o pkg/diagnostcis:
1175      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1176    o pkg/my82,pp81,kl10:
1177      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1178        field diffKr as background diffusivity to set minimum diffusivity value.
1179    o pkg/seaice:
1180      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1181        Bouillon et al 2013)
1182      - add SEAICE_evpAlpha/Beta to namelist
1183      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1184        involve trivial re-ordering of divisions/multiplications that should not
1185        have any effects, but ... they do change the results of lab_sea.hb87 so
1186        that only 2 digits of agreement remain, in line with the general
1187        instability/fragility of the evp-code. For now, I do not care and just
1188        update the verification experiment
1189    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1190      - remove xx_genarr2d_numsmooth etc
1191      - use xx_genarr2d_preproc etc instead
1192      - carry out smooth_correl2D at initialization stage rather than during
1193        time stepping.
1194      - get smoothOpNb from xx_gentim2d_preproc
1195    o global_oce_cs32 :
1196      - add test of generic ecco capabilities.
1197    o pkg/exf/exf_getsurfacefluxes.F :
1198      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1199    o pkg/ctrl,ecco :
1200      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1201        is defined.
1202    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1203    o model/src:
1204      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1205        diffusivity (background) is specified but ignored.
1206    o verification:
1207      - in testreport, convert hostname to lower case for default output dir name
1208    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1209    o pkg/dic: add modifications from Hajoon:
1210      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1211      - light attenuation: add self-shading effect by climatological Chlorophyll
1212        (read from file).
1213    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1214        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1215    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1216        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1217        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1218        approach where CPP_OPTIONS.h includes an omnipotent
1219        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1220    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1221        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1222    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1223        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1224        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1225    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1226      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1227      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1228      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1229      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1230    o pkg/ctrl,ecco,exf :
1231      - remove variables associated with NON-generic costs,
1232        unless ECCO_CTRL_DEPRECATED is defined.
1233      - remove NON-generic NON-obcs controls,
1234        unless ECCO_CTRL_DEPRECATED is defined.
1235    o pkg/ctrl : added ctrl_local_params.h
1236    o pkg/ecco : added ecco_local_params.h
1237    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1238        experiments, which will progressively be removed once the
1239        experiments are revised to use only generic controls/costs.
1240    
1241    checkpoint65f (2014/10/13)
1242    o pkg/ctrl, ecco, seaice : minor changes in headers
1243    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
1244        cost function and control capabilities added since checkpoint65c.
1245    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1246    o pkg/ecco: increase modularity and improve logic
1247      - ecco_toolbox.F (new) : basic operations that are often used,
1248        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1249        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1250      - cost_gencal.F (new) : determine filnames and records.
1251      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1252      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1253        and exploit the above functions leading to more compact code.
1254      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1255      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1256        using_ers, using_gfo, using_mdt is now only defined within gencost)
1257    o pkg/ecco: extend generic cost capabilities
1258      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1259        capabilities via gencost_preproc (+ _c,_i,_r related params),
1260        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1261        gencost_outputlevel arguments to cost_generic
1262      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1263        and active_read, making room for gencost_preproc to take effect.
1264        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1265      - pkg/ecco/cost_generic.F :
1266        compute and store misfit maks*(model-data) in localdif that is
1267        then used in cost and for output, output misfit if outlev.GT.0
1268      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1269        rather gencost_barfile for deciding whether to write barfile
1270      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1271      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1272        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1273      - pkg/ecco/ecco_summary.F : report gencost variables
1274      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1275    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1276    o pkg/ecco: internal re-organization
1277      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1278        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1279        mv relevant variables definition from ecco_cost.h to ecco.h,
1280        make sure gencost routines only include ecco.h)
1281      - throughout : add missing CCP switches, rm unused variables,
1282        and rm un-necessary CPP switches
1283      - throughout gencost routines : replace modelstartdate with
1284        gencost_startdate when needed
1285      - cost_bp_read.F : use arguments, instead of common blocs
1286        so that it can be used also by (new) cost_gencost_bpv4.F
1287      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1288      - ecco_phys.F : compute etanFull
1289      - ecco_readparms.F : rename using_topex as using_tpj, add
1290        bpv4-grace to gencost list, initialize added parameters
1291      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1292    
1293    checkpoint65e (2014/09/28)
1294    o pkg/obcs:
1295      - replaced the just-added CPP options with run-time variables
1296        (see pkg/obcs/OBCS_PARAMS.h for details)
1297    o pkg/obcs:
1298      - add additional CPP options for sponge boundary layers
1299        (see pkg/obcs/OBCS_OPTIONS.h for details)
1300    o pkg/atm_phys:
1301      - implement simple (obliquity only, assuming circular planet orbit)
1302        seasonal cycle for incoming insolation ; used when run-time parameter
1303        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1304    o pkg/exf, pkg/ecco, pkg/ctrl:
1305      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1306      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip

1313        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1314      - add weight in CTRL_GET_GEN calls
1315    o pkg/ctrl :
1316      - ctrl_get_gen.F : add weight as input parameter, and apply
1317        it directly rather than using smooth_correl2Dw (to be retired).
1318      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1319    o pkg/ctrl :
1320      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1321        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1322      - re-activate ctrl_summary (call in ctrl_init.F)
1323    o pkg/ctrl/ctrl_cost_gen.F :
1324      - fix CCP brackets, remove un-necessary myiter, mytime
1325    o pkg/ecco, pkg/ctrl :
1326      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
1327      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
1328      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
1329      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1330    
1331    checkpoint65d (2014/09/15)
1332    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :

1352      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
1353        (moved to ctrl_init_variables)
1354    o ctrl/ctrl_map_ini_ecco.F :
1355      - remove ECCO_PHYS (mv to ecco_init_varia)
1356      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1357    o ecco/ecco_ad_diff.list :
1358      - add ecco_init_varia.f
1359    o ecco/ecco_init_varia.F
1360      - new routine
1361    o pkg/streamice:
1362      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1363        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1364      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1365    o pkg/generic_advdiff:
1366      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1367    o pkg/exf:
1368      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1369         xxg_precip capability
1370      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1371    o pkg/ctrl:
1372      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1373    o model/src/load_fields_driver.F :
1374      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1375        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1376    o OpenAD verification experiments:
1377      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1378        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1379        for now, only in pkgs used in OpenAD verification experiments.
1380      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1381        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1382        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1383        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1384    o OpenAD verification tests:
1385      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1386      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1387        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1388      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1389        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1390    o model/src & generic_advdiff:
1391      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1392        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1393        dynamics requires valid tracer forcing only over tile interior but, for
1394        some diagnostics, may need to extend it over 1 point in tile halo region.
1395      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1396        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1397        setting in temp/salt/ptracer_integrate.F
1398    o pkg/dic:
1399      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1400        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1401        in gchem_forcing_sep.F
1402    o pkg/autodiff & obcs:
1403      - add storage of current OB values for U & V (was already done for T & S).
1404    
1405    checkpoint65c (2014/08/30)
1406    o pkg/dic:
1407      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1408        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1409        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1410    o verification:
1411      - new experiment testing OBCS and DIC pkgs, using params & output from
1412        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1413        passage: take OBCS from the last year of a 2 yrs simulation and initial
1414        conditions from t=1.yr while keeping the same forcing.
1415    o model/src:
1416      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1417        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1418    o pkg/diagnostics (Stats-Diags):
1419      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1420        a) refine region where stats are computed, excluding where arrhFac=0 ;
1421        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1422        c) extend regional stats over the region edges (for U or V pt location).
1423    o pkg/gchem:
1424      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1425        pkg/dic is currently changing/updating ptracers values beyond the OB).
1426    o verification (hs94):
1427      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1428        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1429        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1430        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1431    o pkg/ptracers:
1432      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1433        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1434      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1435        with AB-2 code (so that it get tested).
1436    o model/src:
1437      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1438        with AB-2 code (previously only available with AB-3 code).
1439        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1440        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1441        there, by calling CYCLE_AB_TRACER).
1442    o pkg/generic_advdiff:
1443      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1444        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1445        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1446        S/R temp/salt/ptracers_integrate.F
1447    o model/src & pkg/ptracers:
1448      - remove common block variables gT,gS (in DYNVARS.h), except when
1449         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1450      - remove common block variable gPtr.
1451    o model/src & pkgs:
1452      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1453         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1454         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1455         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1456      + change accordingly all calling S/R.
1457      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1458        in S/R temp/salt/ptracers_integrate.F
1459    o pkg/seaice:
1460      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1461        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1462      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1463        in seaice_lsr
1464      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1465        in s/r seaice_lsr_calc_coeffs
1466    o pkg/mdsio:
1467      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1468        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1469        too long (e.g., > MAX_LEN_FNAM/2 )
1470    
1471    checkpoint65b (2014/08/12)
1472    o pkg/matrix:
1473      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1474    o model/src:
1475      - fix initialisation of geothermalFile; compile geothermal-flux code in
1476        natl_box verification experiment.
1477    o model/src & pkg/down_slope:
1478      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1479      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1480        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1481        results at machine truncation level: update output of experiments
1482        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1483    o pkg/diagnostics (Stats-Diags):
1484      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1485        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1486        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1487        times (but Min,Max and StD are still wrong).
1488    o model/src:
1489      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1490        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1491    o model/src:
1492      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1493        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1494        arrays are already updated while adjustments (filters, conv.adjustment) are
1495        still applied later, in S/R TRACERS_CORRECTION_STEP.
1496    o model/src:
1497      - store in common bloc array "rhoInSitu" the virtual potential temperature
1498        anomaly that is used to compute geopotential: this make the atmos code
1499        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1500    o pkg/seaice/seaice_lsr.F
1501      - rename integer variable ilcall to ipass (that's what it is called
1502        in the residual diagnostics
1503      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1504        default) for improved non-linear convergence of the first few steps
1505      - adjust a few comments and add new ones to explain some of the store
1506        directives
1507    o pkg/generic_advdiff (& ptracers):
1508      - re-work the code to check for valid advection scheme and for minimum
1509        size of overlap (now stored in local common bloc in gad_advscheme.F)
1510    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1511      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1512      - add an auxilliary variable "bet" and fix store directives and keys in
1513        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1514        less exact gradients in my tests); but there are still
1515        recomputation warning (although gradients are sort of OK), when
1516        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1517        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1518      - update verification experiments lab_sea.
1519      - change some comments in S/R seaice_calc_viscosities
1520    o model/src:
1521      - if staggerTimeStep=T, always apply exchange to velocity field in
1522        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1523        (independent of using multi-dim advection or not); no effect on FWD run
1524        but affects AD results (at machine truncation level): update output of
1525        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1526        and isomip (oad: 12.d).
1527    o pkg/generic_advdiff:
1528      - stop if doAB_onGtGs is set to FALSE but ignored
1529      - refine warning related to stability of tracer time-stepping
1530        regarding internal wave dynamics.
1531      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1532        on staggerTimeStep & implicitIntGravWave (will now get a warning
1533        if potentially unstable).
1534    o pkg/kl10:
1535      - add new pkg "kl10" for mixing due to internal wave breaking, from
1536        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1537        (contribution from Jody Klymak), tested in verification experiment
1538        verification/internal_wave/input.kl10/
1539    o isomip experiment:
1540      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1541        (input.htd) and update the output.
1542    o cd_code experiments:
1543      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1544        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1545        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1546        update the corresponding output.
1547    o pkg/seaice:
1548      - reduce the number of include files and store directives in
1549        S/R seaice_lsr_tridiagu/v
1550      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1551        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1552        get rid off one store directive (a TAF bug?)
1553      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1554        S/R seaice_lsr_tridiagv to change the loop range for consistency
1555      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1556      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1557        S/R seaice_lsr_tridiagu/v (requires update of
1558        offline_exf_seaice/input.dyn_jfnk)
1559    
1560    checkpoint65a (2014/07/27)
1561    o model/src:
1562      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1563        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1564        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1565        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1566    o model/src:
1567      - collect momentum forcing tendency into local 2-D array (passed as argument
1568        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1569        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1570        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1571      - collect T & S forcing tendency into local 2-D array (passed as argument to
1572        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1573        affects results at machine truncation level (e.g., ocean: if using
1574        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1575        correction due to vertical advection).
1576      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1577        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1578        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1579        obcs_ctrl (ad & fwd grd @ 12 & 7).
1580    o pkg/ptracers & diagnostics:
1581      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1582        title (to avoid some unexpected truncation); sort out ptracers diags units.
1583      - collect ptracer forcing tendency into local 2-D array (passed as argument
1584        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1585    
1586    checkpoint65 (2014/07/18)
1587    o pkg/fizhi:
1588      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1589        affects results at machine truncation level. Update output of experiments
1590        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1591    o pkg/seaice: more clean up
1592      - rename TAF common block tapes to be more consistent and remove
1593        unnecessary duplicates
1594      - add store directives to remove more recomputations, but use smaller
1595        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1596        The idea behind this flag is to reduce the memory footprint when the
1597        adjoint of the LSR is not required. As of now, defining the flag
1598        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1599        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1600        For experiment offline_exf_seaice, this means on a linux box with gfortran
1601        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1602        this experiment):
1603        > size mitgcmuv_ad
1604        text    data        bss     dec        hex
1605        5100659 1216  220458952  225560827  d71c8fb
1606        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1607        but only a moderate increase of 36% for global_ocean.cs32x15:
1608        text    data        bss     dec        hex
1609        6695027 1648 1014578664 1021275339 3cdf6ccb
1610        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1611      - note: there are still recomputations in global_ocean.cs32x15 and
1612        offline_exf_seaice and the gradient agreement changes (gets a
1613        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1614      - in general, the AD gradients still are wrong
1615    o OpenAD
1616      - clean up code_oad/ directories somewhat by moving files
1617        dontCompile, dontTransform, keepOriginal to OAD_support/
1618    o model/src:
1619      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1620        (not currently tested): add dissipation terms before NLFS rescaling of
1621        tendencies (previously done after).
1622    o pkg/diagnostics:
1623      - write stats-diags in ascii file with more digits (same as in monitor).
1624    o pkg/down_slope:
1625      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1626        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1627    o model/src:
1628      - new file "apply_forcing.F" containing all the code previously in
1629        external_forcing.F, but with new argument list: pass, as new argument,
1630        the current level tendency array to update (instead of a direct update
1631        of the common bloc array). Change the corresponding calls.
1632      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1633        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1634    o pkg/seaice/seaice_lsr, a little bit of clean up
1635      - rearrange some code blocks, so that now all calculations for
1636        setting up the right-hand-sides done within one single block
1637        (I find that easier to read and understand)
1638      - rearrange freedrift-code to reduce the number of ifdefs
1639      - adjust some indentations and comments
1640    
1641    checkpoint64z (2014/07/10)
1642    o model/src and several pkgs:
1643      - change argument list of all S/R called from external_forcing.F and
1644        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1645        to pass, as argument, the current level tendency array to update
1646        (instead of a direct update of the common bloc array).
1647      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1648      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1649    o pkg/seaice/seaice_lsr.F
1650      - always initialize local arrays in seaice_lsr_tridiagu/v
1651      - add more local tapes to seaice_lsr_tridiagu/v
1652      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1653        keep it in bi/bj loop; this seems to be essential
1654      - gradients are still wrong but only by 4-7 orders of magnitude
1655        instead of 15 orders of magnitude, lab_sea improves a little
1656    o pkg/seaice
1657      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1658        generates unnecessary code in seaice_lsr_ad
1659      - add more store directives in seaice_lsr to avoid unnecessary code
1660        in seaice_lsr_ad
1661      - exclude some residual computations in seaice_lsr when
1662        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1663        in seaice_lsr_ad
1664      - add more storing, a new tape (model/src/the_main_loop.F) and
1665        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1666        and klockey should be checked by a specialist)
1667      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1668        and update lab_sea after previous changes in pkg/seaice below
1669    o pkg/autodiff:
1670      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1671        viscFacInAd : run time parameters allowing for adjoint switches
1672        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1673    o pkg/ecco:
1674      - introduce cost_gencost_boxmean.F that computes a box mean
1675        temperature (for use in adjoint sensitivity studies).
1676    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1677    o pkg/mom_common/mom_calc_visc.F:
1678      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1679    o pkg/seaice/seaice_summary.F:
1680      - statement for SEAICEadjMODE now in autodiff_readparms.F
1681    o pkg/seaice:
1682      - remove some store directives and add new ones in an effort to get
1683        finally rid off the recomputation warnings. This is successful
1684        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1685        defined (i.e. no extensive recomputation warnings left), but there
1686        are still too many recomputations on the solver iteration level
1687      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1688      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1689        SEAICE_SIZE.h
1690      - add a store directive in S/R seaice_calc_viscosities
1691    o pkg/seaice (ITD code):
1692      - fix definition of Hlimit for multi-threaded case
1693      - use double precision arithmetic to compute Hlimit: this affects results;
1694        update output of experiment seaice_itd.
1695    o replace content of verification/seaice_itd
1696      - instead of a 1D column use the configuration of offline_exf_seaice
1697        to test the ice thickness distribution code with ridging
1698      - this is a first shot at this experiment
1699      - change of some defaults of ridging parameters SEAICEhStar (from
1700        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1701        and lot of new comments.
1702    
1703    checkpoint64y (2014/06/20)
1704    o pkg/seaice/seaice_reg_ridge.F:
1705      - modify the regularization of very small volumes of ice; only check
1706        total volume HEFF, and do not apply correction to individual ice
1707        classes because that leads to funny patterns in the heat and fw-fluxes
1708        into the ocean. Adjust seaice_itd/results/output.txt
1709      - replace nITD by SEAICE_multDim in loop-ranges
1710    o pkg/exf:
1711      - add code to process the case field period = -12. with UV interpolation.
1712      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1713        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1714    o verification/global_with_exf:
1715      - switch all fields period to -12. (was previously untested) in input/data.exf
1716        (but keep secondary test ".yearly" unchanged); update the reference output.
1717    o pkg/cal:
1718      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1719    o pkg/exf:
1720      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1721        to replace logical switch "exf_verbose"
1722      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1723    o pkg/sbo:
1724      - update from Katherine Quinn: evaluate mass directly from density and SSH
1725        (budget using Finite Volume method) instead of from bottom pressure.
1726      - allow testreport to collect few selected SBO output ; tested in exp.
1727        global_ocean.90x40x15 (after updating the results, to include SBO output).
1728      - fix some multi-threading issues (in output part).
1729    o model/src & most packages:
1730      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1731      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1732        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1733        "data.{pkg}" exist ; and leave the S/R (return) just after.
1734      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1735        + call LAND_READPARMS from packages_readparms.F
1736    o pkg/seaice:
1737      - remove code that resets useThSice in S/R seaice_readparms and
1738        replace it by a warning in S/R seaice_check
1739      - remove parameter MULTDIM, replace with nITD and runtime
1740        parameter SEAICE_multDim (still hard-wired to nITD if
1741        SEAICE_ITD is defined)
1742    
1743    checkpoint64x (2014/05/24)
1744    o verification/lab_sea:
1745      - update adjoint and TLM output following changes to pkg/salt_plume
1746      - un-do the update after putting back local recip_Cp in few places.
1747    o pkg/salt_plume: modifications by An Nguyen:
1748      - add capability to do brine rejection (salt-plume) as function of
1749        volume+tracers (instead of only salinity tracer).
1750      - conserve volume by exchanging volume from each kLev to above to
1751        accommodate in-coming brine volume
1752      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1753      - switch KPP surf buoyancy due to brine forcing to 3-d
1754        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1755      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1756      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1757        in East/West Arctic.
1758    o pkg/sbo:
1759      - incorporate modifications from Katherine Quinn to enable the use of sbo
1760        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1761        output for future testreport verification (unfinished).
1762    o pkg/atm_phys:
1763      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1764        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1765        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1766    o pkg/seaice
1767      seaice_calc_ice_strength.F: modify expression to avoid divisions
1768        (affects truncation)
1769      seaice_do_ridging.F: clean up the insectarium
1770      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1771      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1772      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1773      - add some debugging information and error messages (warnings)
1774    o model/src: modifications relatd to atmosphere p*:
1775      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1776      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1777        of vertical profile tRef in geopotential background and anomaly.
1778      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1779        and pkg/atm_phys.
1780      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1781        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1782    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1783    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1784        not used right now, but can be used in BGC packages to fix conservation.
1785    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1786        other packages too.
1787    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1788        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1789    o model/src:
1790      - since we have several heat capacity (even in model/src), define "recip_Cp"
1791        as local variable (no longer in common block) to avoid any confusion.
1792      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1793    o pkg/exf:
1794      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1795        air density as function of air Temp, Humidity and atm pressure.
1796    
1797    checkpoint64w (2014/05/02)
1798    o verification:
1799      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1800        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1801        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1802        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1803        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1804    o model/src: for atmosphere in p* coords:
1805      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1806      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1807        but not yet activated.
1808    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1809      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1810      - this changes the results (but not for any verification experiment, because
1811        none tests this), but avoids having an extra field in the restart files
1812    o pkg/seaice: remove global variable TICE (not needed)
1813      - replace by TICES or local variable where necessary (cost_seaice_test,
1814        seaice_diagnostics_state)
1815      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1816      - use specific read/write routines for reading and writing individual leves
1817        of a multilevel field
1818    o pkg/ctrl & model/inc:
1819      - move additional anomaly fields of control vars (related to options:
1820         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1821        from DYNVARS.h into new header file: CTRL_FIELDS.h
1822    o pkg/seaice: some small modifications to the ridging code
1823      - make fw2ObyRidge a global variable and add the freshwater flux to
1824        seaice_growth
1825      - pass actual thickness from seaice_prepare_ridging, so that it is
1826        computed only in one place and compute it in the same way as in
1827        seaice_growth
1828      - initialise more fields in seaice_do_ridging that where cause floating
1829        point exceptions over land
1830  o pkg/seaice: preparations for ridging code and first real ridging code  o pkg/seaice: preparations for ridging code and first real ridging code
1831    - move most of "PART 1" of S/R seaice_growth into a new and separate    - move most of "PART 1" of S/R seaice_growth into a new and separate
