4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate  o model/src:
8    AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than    - add specific run-time param to select level of printed plot-field-maps,
9    ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,      set by default to debugLevel. Remove internal param "printDomain".
10    approach where CPP_OPTIONS.h includes an omnipotent  o pkg/seaice:
11    ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').    - add flag to add snow mass to seaiceMassC/U/V, the default is
12  o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where      SEAICEaddSnowMass=.FALSE., not to change previous results
13    ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.  o pkg/bling
14      - Bug fix in bling_production regarding unit conversion for diagnostics
15        being put in the wrong place
16    o model/src:
17      - add back recomputation of rSurfW & S to ensure consistent column thickness
18        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
19        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
20        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
21    o pkg/autodiff:
22      - clean-up "checkpoint.flow"
23    o pkg/rw (Contribution from Jody Klymak):
24        option to set mds file suffix as function of time in simulation:
25        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
26           to select file suffix format; by default (=0), use iteration number;
27        *) add simple routine to return file suffix according to rwSuffixType;
28        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
29           use new S/R to get file suffix, except for debug output file (diagFreq)
30           and pkgs offline & rbcs input files.
31    o pkg/rw:
32      - uniform processing of "I10" suffix across writing fld routines; used to
33        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
34        (similar to cg3d.F, cg3d_ex0.F)
35    o pkg/mom_vecinv:
36      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
37        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
38    o pkg/bling:
39      - Many small changes intended to clean the code.
40        Unnecessary ADJOINT_SAFEs removed ;
41        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
42        diagnostics added.
43    
44    checkpoint66e (2017/03/14)
45    o pkg/exf:
46      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
47        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
48        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
49        avoid any dynamic allocation ;
50      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
51        read-in ; add warning when file is read-in but not used within pkg/exf ;
52        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
53      - update exf_summary.F (print {FLD}RepCycle).
54    o verification/global_with_exf:
55      - switch on exf interpolation in AD test (just like the forward test)
56    o pkg/mom_vecinv:
57      - add storage directives to avoid recomputations within mom_vecinv.F
58        which were generating seg. fault with gfortran -devel
59    o pkg/ctrl, pkg/smooth:
60      - initialize array halos which were generating seg. fault with
61        gfortran -devel in adjoint mode
62    o pkg/exf:
63      - for each input field, enable to specify a field specific repeat-cycle
64        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
65    o verification/lab_sea:
66      - update AD results of primary test and noseaicedyn test after switching
67        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
68        check stays about the same.
69    o pkg/exf:
70      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
71      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
72    o pkg/bling, USE_EXFCO2 code:
73      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
74      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
75    o pkg/exf:
76      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
77      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
78        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
79        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
80      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
81        EXF_INIT_FLD) and update calls in exf_init_varia.F
82      - For now, for backward compatibility, keep a simplified version of S/Rs
83        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
84      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
85        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
86    o tools/genmake2:
87      - replace "bc -l" (only used once) by "expr" (already used).
88    o verification/global_ocean.cs32x15:
89      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
90        Note: exf setting (data.exf) can be compared to other exf secondary exp
91        "seaice" (kept with useCAL=T) which has same time dependent forcing.
92    
93    checkpoint66d (2017/02/13)
94    o pkg/exf:
95      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
96        early on (in packages_boot.F) to stress this change in pkg setting.
97      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
98    o model/src:
99      - move call to ecco_phys to end of time step; this may induce minor
100        cost function changes by shifting time averages by one time step
101        for some variables; this revision resulted in changed adjoint results
102        in MITgcm_contrib/verification_other/global_oce_cs32
103    o pkg/exf:
104      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
105        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
106        e.g. precip, are not available.
107    o pkg/flt:
108      - flt_init_varia.F: use pickupSuff if specified
109      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
110        intermediate, step towards completing pkg/exch2 support within pkg/flt;
111        ifdef DEVEL_FLT_EXCH2 then:
112        - flt_init_fixed.F: comment out stop
113        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
114        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
115        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
116        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
117    o tools/genmake2 & pkg/pkg_depend:
118      - define new type of pkg dependency rule ("=pkg_x"), less strict than
119        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
120        (-pkg_x in packages.conf).
121      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
122      - add "+cal" to dependency list of pkg/ecco (needed to compile).
123      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
124    o utils/matlab:
125      - adding ocean_basin routines for defining basin masks.
126    o pkg/exf:
127      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
128        arguments, allowing to check (and stop) if parameter setting of
129         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
130        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
131        for backward compatibility.
132      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
133        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
134    o pkg/bling (USE_EXFCO2 code):
135      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
136        by adding a call to S/R EXF_GETFFIELD_START.
137    o pkg/exf:
138      - allows to compile without pkg/cal (but disabled by current dependency
139        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
140        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
141        of {FLD}startdate1 & date2 ; consistency check not yet coded.
142    o verification/global_ocean.cs32x15:
143      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
144        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
145    o pkg/exf:
146      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
147        calculations); change FWD experiment global_ocean.cs32x15
148        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
149    o pkg/exf:
150      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
151         {FIELD}startdate to {FIELD}StartTime
152        Note: new name also fit better the content, i.e, a start time in second.
153    o eesupp/src:
154      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
155    o pkg/exf:
156      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
157        to allow to read-in Sensible & Latent Heat flux ;
158      - simplify pkg/exf main options:
159        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
160           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
161           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
162        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
163           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
164        3) improve options documentation in EXF_OPTIONS.h.
165    o pkg/ecco:
166      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
167        ecco_summary.F: add passive tracer cost functions to gencost;
168        m_ptracer and m_boxmean_ptracer
169    o pkg/ctrl:
170      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
171        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
172        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
173        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
174    o model/src:
175      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
176        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
177    o pkg/exf:
178      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
179        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
180    
181    checkpoint66c (2017/01/19)
182    o verification:
183      - add new option "-src" to testreport to only produce source code (*.f),
184        including taf output src code (if using '-adm'/'-tlm' option).
185    o pkg/exf:
186      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
187    o pkg/diagnostics:
188      - add run-time variable diagMdsDir to specify a subdirectory for
189        diagnostic output when mds is being used and mdsioLocalDir is not.
190    o pkg/mnc:
191      - mnc_utils.F: edit stop message
192    o pkg/autodiff:
193      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
194        add HAVE_SYSTEM bracket around system call to mkdir
195    o pkg/profiles:
196      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
197        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
198      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
199        add HAVE_SYSTEM bracket around system call to mkdir
200    o pkg/smooth:
201      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
202      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
203      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
204    o pkg/exf:
205      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
206        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
207        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
208      - summary: skip detailed field report if not used (empty file-name).
209    o tools/xmakedepend:
210      - In case line editor "ed" is missing, switch to "sed" command to clean-up
211        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
212    o pkg/exf:
213      - change definition of "hflux" input file to always include Short-Wave;
214        this is now consistent with hflux computation (if using bulk-formulae)
215        and hflux diagnostic & documentation (in EXF_FIELDS.h).
216    
217    checkpoint66b (2016/12/01)
218    o model & momentum pkgs:
219      - implement fully implicit bottom friction combined with implicit surf.
220        pressure, for now, only in hydrostic formulation:
221        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
222          and run with selectImplicitDrag=2 ;
223        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
224      - partial implicit time-stepping (bot. friction + vert. visc first, then
225        surf. press) corresponding to selectImplicitDrag=1 should be applicable
226        to NH formulation but not available until we solve for surf. pressure
227        increment (instead of full etaN).
228      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
229        with implicit vertical viscosity.
230    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
231      - this is a first version that includes many regularisations that may
232        not all be necessary, to be sorted out,
233      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
234      - change one verification experiment in seaice_itd to use and test new code
235      - seaice_growth: catch a case where the argument of log can be zero
236        or smaller (important for code stability)
237    o model/src:
238      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
239        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
240        similar A.X'=Y' system (with same matrix A) in subsequent calls;
241        switch based on errCode (In/Out) argument value; in calling routines,
242        initialise errCode before first call.
243    
244    checkpoint66a (2016/10/18)
245    o pkg/bling:
246      - BLING package now loads in atmospheric pCO2 file using exf package routines
247        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
248    o model/src & pkg/ptracers:
249      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
250        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
251        implicitDiffusion (respectively) are used (even without momImplVertAdv
252        or temp,salt,PTRACERS_ImplVertAdv).
253    o model/src & generic_advdiff:
254      - add parenthesis in main diagonal calculation of implicit vertical
255        diffusion matrix (impldiff.F & gad_implicit_r.F).
256        This affects results at machine truncation level; update output of many
257        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
258    o pkg/mom_commom & generic_advdiff:
259      - add deep atmosphere and anelastic scaling factor in implicit vertical
260        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
261    o model/src:
262      - remove few unnecessary temp array copies in solve_tridiagonal.F
263        & solve_pentadiagonal.F
264    
265    checkpoint65z (2016/09/28)
266    o pkg/seaice: fix multithreading for seaice_fgmres.F
267      - remove unecessary variables from common blocks
268      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
269        basis, that are stored in commom blocks (including integer variable i1)
270      - clean up code a little by removing commented lines that refer to
271        original code
272      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
273    o MITgcm manual:
274      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
275        preliminary documentation for generic controls (8.3; ctrl.tex),
276        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
277        ecco_costfunction.tex
278    o pkg/ecco:
279      - update and cleanup list of CCP options
280      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
281        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
282      - add checks that retired run-time options are not used, and in relation
283        to gencost_mask and gencost_errfile
284      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
285        gencost_nrecperiod
286      - fix m_eta computation for virtual salt flux case
287      - add m_horflux_vol case (selected via gencost_barfile) that computes
288        transports via cost_gencost_boxmean (gencost_flag=-3)
289      - use gencost_flag more systematically (i.e., avoid using gencost_name)
290        for code switches (aside from physical variable selection)
291    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
292      attempt appears to be a bit of a hack and my need some repair down the road
293    o pkg/exf:
294      - interpolation near South Pole: fix criteria on input field latitude.
295    o pkg/icefront & pkg/exf:
296      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
297        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
298    o pkg/exf:
299      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
300        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
301        (add suffix "_out" instead of a prefix); keep same record number as in
302        input file but always write record 1 first (to avoid a STOP in I/O S/R).
303        Change output file content by writing interpolated field before applying
304        land-sea mask (helpful for debug).
305      - 2 compon. vector interpolation with rotation: apply scaling factor on
306        each compon. (Eastward and Northward) just before rotation.
307    o pkg/bling:
308      - Cleaned package. Removed not needed code and comments.
309      - adjoint example now works
310        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
311    o pkg/ptracers:
312      - add Bruno Deremble's code to complete the linear surface correction
313        for tracer conservation;
314      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
315    
316    checkpoint65y (2016/07/29)
317    o pkg/debug (stats):
318      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
319        proc/thread mapping);
320      - fix Min & Max for case where 1 thread has only empty tiles;
321      - use RL variable to count number of wet grid points (with big domain,
322        can be too large to fit into integer*4).
323    o pkg/monitor:
324      - use RL variable to count number of wet grid points (but used only for del2)
325      - add new routine to compute Advective CFL within tracer time-stepping with
326        writing delayed until next monitor output.
327    o pkg/obcs:
328      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
329    o pkg/cal:
330      - calandar-dump: treat case myTime < timePhase in the same way as in
331        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
332    o pkg/dic & seaice:
333      - fix compilation of ocean component for coupled atm+ocn model with
334        seaice dynamics & dic.
335    
336    checkpoint65x (2016/06/11)
337    o add a license text file in main MITgcm tree.
338    o added pkg/bling:
339      - intermediate complexity biogeochemical model
340      - see bling_description.txt for details
341      - verification experiment is global_oce_biogeo_bling (for now, in
342        Contrib/verification_other/); tested daily on baudelaire with gfortran.
343      - add entry point in pkg/gchem for new pkg "bling".
344    o pkg/seaice: fix tensile stength computation
345      - replace global field tensileStrength by tensileStrFac
346      - tensileStrFac can be computed once in S/R seaice_init_varia
347      - fortunately that does not affect any verification results
348    
349    checkpoint65w (2016/05/12)
350    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
351         with ECCO_CTRL_DEPRECATED defined
352    o verification/global_ocean.cs32x15:
353      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
354        with "selectNHfreeSurf=1".
355    o model/src (non-hydrostatic free-surface):
356      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
357        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
358      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
359        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
360        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
361        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
362      - Update output (changes at machine truncation level) of verification exp:
363        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
364        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
365    o pkg/seaice: ITD code
366      - fix picking up from a single category model by initialising
367        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
368      - split a long warning message in seaice_check_pickup.F into two lines,
369        because NEC SX-ACE cannot deal with the long line.
370    o model/src:
371      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
372    o pkg/seaice:
373      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
374    o pkg/seaice:
375      - add basal stress as parameterisation for grounding ice
376        following Lemieux et al. (2015)
377      - turn on by setting new parameter SEAICEbasalDragK2 to a value
378        larger than 0. Lemieux et al. (2015) recommend 15.
379      - The adjoint complains with extra recomputations so there is also a
380        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
381        order to postpone the problem
382      - compile the new code in lab_sea
383    o verification/halfpipe_streamice:
384      - update both TAF and OpenAD adm output (machine truncation differences)
385    
386    checkpoint65v (2016/04/08)
387    o verification/advect_xz:
388      - increase overlap size from 3 to 4 and add new secondary test for PQM
389        advection scheme (with mono & wino limiter).
390      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
391    o model/src:
392      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
393        added phi0Ref) to set vertical axis origin and phiRef origin;
394        keep Ro_SeaLevel for backward compatibility (with a warning).
395       According to coordinate and fluid type:
396        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
397        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
398        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
399        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
400      - remove Ro_SeaLevel from ATM experiment parameter files;
401      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
402        complement; update output.txt (changes at machine truncation level).
403    o pkg/seaice/seaice_evp.F
404      - simplify computation of deltaZ and zetaZ to simple averaging following
405        Bouillon et al. (2013). This removes a lot of code, but also changes
406        verification experiment lab_sea.hb87 -> updated
407    
408    checkpoint65u (2016/03/14)
409    o pkg/generic_advdiff:
410      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
411        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
412        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
413        testing and not for actual use.
414    o model/src:
415      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
416        origin r = rF(1);
417      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
418        in EOS for height coordinate: enable to include NH Pressure or to use
419        more accurate pressure vertical profile; options not linked to EOS type
420        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
421      - start to implement variable gravity (along vertical): for now, only with
422        z-coords (not even z*).
423      - add Ideal Gas equation of state for height coordinate.
424      - update OpenAD output (affected at machine truncation level) of exp:
425        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
426    o pkg/exf:
427      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
428        of exf interpolation (before any rescaling, rotation or interpolation
429        to velocity point) for each field that gets loaded from file. This option
430        identically mimics the input file organization (e.g. record numbers in year
431        by year input files) besides the change in horizontal grid.
432      - add rotateStressOnAgrid run-time switch so that wind stress fields
433        can be provided on the A-grid in zonal/meridional direction and
434        rotated on the fly. This only applies to the case when the exf
435        interpolation is off and rotateStressOnAgrid is false by default.
436    o model/src:
437      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
438        it's also used with pkg/atm_phys) and add few more parameters (but still
439        inactive, src code yet to come)
440    
441    checkpoint65t (2016/02/10)
442    o pkg/atm_phys:
443      - from Ruth Geen: add optical depth dependence on CO2 concentration.
444    o model/src:
445      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
446        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
447        Update output of exp. deep_anelastic (changes at truncation level).
448    o tools:
449      - add a hack in "remove_comments_sed" (used only with TAF) for recent
450        version of OpenMPI (shipped with FC.23): comment out the new header
451        file "mpif-sizeof.h" which causes problems to TAF.
452    o pkg/seaice:
453      - change the termination criterion so that maxits (SEAICElinearIterMax)
454        has an effect
455      - unify iteration parameters for implicit solvers (JFNK and Picard)
456        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
457        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
458        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
459        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
460        SEAICEnonLinTol     replaces JFNKgamma_nonlin
461      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
462      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
463        use with SEAICEuseKrylov
464    o pkg/seaice/seaice_lsr.F
465        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
466        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
467        an effect.
468    o pkg/seaice: add two new parameters
469      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
470        parameter is not in any namelist)
471      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
472        a preconditioner for the non-linear Newton iteration of the JFNK
473        solver
474    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
475      affects some experiments at truncation level:
476      - global_ocean.cs32x15.icedyn (11 digits),
477      - global_ocean.cs32x15.seaice (11 digits),
478      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
479      - also update global_ocean.cs32x15 adjoint and tangent-linear results
480    o pkg/salt_plume & pkg/thsice:
481      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
482        connect salt_plume flux to ATM-OCN coupling pkgs interface:
483       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
484         export to coupler interface) even without compiling pkg/salt_plume ;
485       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
486         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
487    o pkg/dic:
488      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
489        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
490        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
491      - move also update with values from ATM-OCN Coupler in the same new S/R
492        (previously done in ocn_apply_import.F).
493    o tools/adjoint_options:
494      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
495        has been changed on Jan 14, 2016.
496    o pkg/ggl90:
497      - add alternative discretisation of vertical shear (off by default), to
498        compute the mean (@ grid-cell center) of vertical shear compon instead of
499        vertical shear of mean flow (@ grid-cell center).
500      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
501        results on adjacent faces of cubed-sphere grids; this fix the restart.
502    o pkg/atm_compon_interf:
503      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
504        pass last value, stored directly before export to CPL ;
505        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
506      - remove atmSLPr from pickup files (no longer needed for restart)
507    
508    checkpoint65s (2016/01/13)
509    o eesupp & genmake2:
510       - first check for Function ETIME and, if it fails, then check for subroutine
511         ETIME and consistent output; use the appropriate version in timers.F
512    o model/src:
513      - to check restart test, add option to apply EXCH to U,V earlier, just before
514        integr_continuity; turned off by default.
515    o pkg/dic:
516      - remove CPP option USE_ATMOSCO2 (not needed)
517    o tools/tst_2+2:
518      - try to ignore difference between +0 and -0 in binary file, causing test
519        to fail for no good reason.
520    o eesupp & genmake2:
521      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
522        but also check (in genmake2) that test runs and returns meaningful results.
523    o coupler pkgs:
524      Finish implementation of optionally-exchanged variable switches (started on
525       Nov 12) with addition of few more exchanged fields, including 2-way exchange
526       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
527       advection in OCN component; this requires sequential coupling.
528      coupler (pkg/atm_ocn_coupler):
529      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
530        routines (useful for debug).
531      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
532         flux, DIC fields) if corresponding switch is ON.
533      - add option to export RunOff to OCN (to use for DIC river input)
534      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
535      components (pkg/atm_ & ocn_compon_interf):
536      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
537        optionally exchanged fields; add a check & stop in cpl_readparms.F.
538        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
539        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
540      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
541        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
542      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
543      - hold in common block coupler optionally-exchanged variable switch
544        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
545      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
546        this is intended to replace the OCN cplFldtave.* output files (not updated
547        to contain new additional exchanged fields).
548    o pkg/dic:
549      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
550    o pkg/thsice:
551      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
552        and writing of thsice pickup files.
553    o pkg/atm_compon_interf:
554      - move all field individual export-call out of cpl_export_import_data.F
555        into new S/R ATM_EXPORT_FIELDS
556    o pkg/atm_compon_interf:
557      - store state variables (for now, only thSIce fields) just before beeing
558        exported (in cpl_export_import_data.F, like on ocean side) instead of from
559        atm_store_my_data.F like all exported fluxes.
560      - new version of pickup_cpl: write field names into meta file and read meta
561        file to find field postion in pickup. Also only write/read fields meeded for
562        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
563    o pkg/dic:
564      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
565    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
566        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
567        value can be from domain [0,1] to average between the two methods
568    o pkg/atm_phys:
569      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
570        hold fixed in time).
571    
572    checkpoint65r (2015/12/21)
573    o pkg/seaice:
574        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
575        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
576    o pkg/seaice:
577      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
578        when SEAICEscaleSurfStress=.TRUE.,
579      - apply areaW and areaS in S/R seaice_calc_lhs
580    o pkg/atm_phys:
581      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
582        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
583        for individual contribution (convection, LSC cond, radiation)
584      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
585        information); activated with: solar_exponent=0. and wv_exponent=-1.
586    o pkg/ggl90:
587      - within IDEMIX add upper limit for horizontal group velocity to
588        avoid instability problems in the explicit horizontal diffusion term for
589        long time steps or high resolution
590    o pkg/diagnostics:
591      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
592        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
593    o testreport:
594      - remove "-v" (verbose option) in default mpirun command.
595    o pkg/seaice/seaice_growth:
596      - catch potential division by zero in ITD code, does not change
597        verification results
598    o pkg/ecco:
599      - retire old codes to the Attic. The calls to retired functions are
600        left in a commented form in case they ever need to be re-activated.
601      - ecco_check.F: issue warning if any old CPP option is
602        defined that corresponds to retired codes -- then stop.
603    o pkg/atm_compon_interf:
604      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
605        coupler: use last time-step value instead of average over cplSendFrq_iter
606        time-step, similar to what is done for seaIceMass.
607        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
608    o eesupp & genmake2:
609      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
610        <= remove until a fix is found for some ifort version on ia32 machine.
611    o pkg/seaice/seaice_evp:
612      - refine residual computation
613    
614    checkpoint65q (2015/11/18)
615    o pkg/seaice/seaice_evp:
616      - fix residual computations so that they no longer affect the actual
617        simulation code
618      - fix seaice_readparams to be able to actually set new parameters
619        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
620    o model/src:
621      - fix wrong truncation (single prec) from "FLOAT" function in expressions
622        like: deltaT*FLOAT(myIter) when myIter is large:
623         a) replaced by DFLOAT (if not seen by TAF);
624         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
625    o pkg/aim_v23:
626      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
627        when pickupSuff is set ; do write rolling pickups + at the end of the run.
628    o pkg/atm_ocn_coupler + ocn_compon_interf:
629      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
630        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
631        add corresponding call in DO_OCEANIC_PHYS.
632    o coupler pkgs:
633      Start a new way to set-up optionally-exchanged variables (previously, only
634       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
635       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
636       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
637       compononent param default can be set accordingly).
638      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
639       but rather applies to a group a fields (going both ways like for DIC)
640       and corresponds to an option of coupling config.
641      coupler (pkg/atm_ocn_coupler):
642      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
643        and read namelist directly (without eessup S/R calls) instead of
644        in the very un-flexible old way, 1 param per line, in fixed order;
645      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
646        cleanly in CPL_CHECK_CPLCONFIG
647      - add new coupling-exchange selectors (some not yet active) including
648        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
649                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
650      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
651        component ; called directly from coupler.F, after comp. registrations;
652      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
653         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
654          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
655      components (pkg/atm_ & ocn_compon_interf):
656      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
657        CPP header file in all pkg source files.
658      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
659        ATM/OCN_CHECK_CPLCONFIG;
660      - add error-counter to track errors (e.g., in "data.cpl") and to stop
661        cleanly in ATM/OCN_CHECK_CPLCONFIG;
662      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
663        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
664        before PACKAGES_READPARMS;
665      verification/cpl_aim+ocn/:
666      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
667        "data.cpl" for coupler (in input_cpl).
668    o eesupp/inc:
669      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
670        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
671        to always cumulate tile local-sum in the same order (still uses
672        MPI_Allreduce like standard code).
673      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
674        that are now identical to standard version (in eesupp/inc).
675    o pkg/shelfice:
676      - add SHELFICETransCoeffTFile for initializing spatially varying
677        heat and salt transfer coefficients
678    o pkg/atm_compon_interf & ocn_compon_interf:
679      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
680        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
681      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
682    o pkg/atm_ocn_coupler:
683      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
684    o pkg/rbcs:
685      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
686        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
687      - add a short report (to STDOUT) about RBCS-mask settings.
688    
689    checkpoint65p (2015/10/23)
690    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
691        there is no adjoint test for EVP, we don't know what it does to the adjoint
692        solution, but at least there are no more recomputation warnings left
693    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
694        a chance of giving the same results as a fully converged VP (JFNK) solver
695    o tools/adjoint_options/adjoint_diva:
696      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
697    o pkg/streamice:
698      - spotted bug in streamice_driving_stress using dyG where should have been dxG
699    o pkg/exf:
700      - remove STOP statement that prevented to use wind or (wind-)stress
701        interpolation for constant-in-time forcing fields (wind/stress period = 0).
702    o pkg/seaice:
703      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
704        5 additionals 2D fields and 6 new store directives
705      - change logic in seaice_readparms.F: EVP code can now be turned on in
706        various ways, setting SEAICE_deltaTev is no longer required,
707        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
708        or SEAICEaEVPcoeff
709    o pkg/shelfice/shelfice_thermodynamics.F
710      - redefining uLoc/vLoc to u/v, instead of 2u/v
711    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
712      - this is an intermediate state of a truely converging EVP that has
713        the potential of outperforming implicit VP methods, I do not recommend
714        using it yet.
715      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
716        and all parameters are hardwired
717      - for convergence it still requires very smooth regularisations, that means,
718        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
719        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
720        specific averaging appears to be required, still subject to tuning
721      - still needs cleaning and I need to turn parameter into runtime parameters
722      - add code to compute and print residuals of iteration, compile with
723        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
724    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
725      that entered with r1.54 on Sep04, 2015, -> update results
726    
727    checkpoint65o (2015/09/14)
728    o pkg/mom_vecinv & mom_common:
729      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
730        called from there.
731      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
732        allows to use Vector-Invariant form in deep atmos and anelastic formulation
733    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
734      and Koenig-Beatty+Holland (2012)
735      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
736      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
737      - requires an extra input argument for S/R seaice_calc_viscosities
738      - tensileStrength's depth dependence is different from Itkin et al. (2015)
739        (to be changed and played with, for now exponential)
740    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
741      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
742        by AREA according to Connelly et al. (2004), JPO.
743      - For EVP and the LSR solver, the implicit part of the drag term is
744        the only non-zero term in the denominator when there is no ice (which
745        prevented running the model with zero ice-ocean drag). If
746        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
747        (or zero main diagonals BU/BV) which need to be caught. A practical
748        consequence is that for open water, the momentum equation reduce
749        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
750        they happen to be zero, often leading to a non-zero solution over
751        open water.
752    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
753        efficient EVP method.
754      - introduce area-weighted averages for e12 (analogously to
755        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
756        remain, but also changing the order of terms in the previous average
757        changed the results as much) -> update experiment
758      - add SEAICE_DELTA_SMOOTHREG code
759      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
760        TEM-code
761      - adjust loop bounds so that only required fields are computed
762      - add new averaging code for zetaZ/deltaZ (again similar to
763        seaice_calc_viscosities.F), inactive by default for now (will change
764        results again), but will replace old code eventually
765    o eesupp/src:
766      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
767        to always cumulate tile local-sum in the same order
768        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
769        Still uses MPI_Allreduce (like standard code) but on array of tiles
770        and should be faster than GLOBAL_SUM_SEND_RECV code.
771      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
772        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
773      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
774         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
775         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
776         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
777         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
778    
779    checkpoint65n (2015/07/29)
780    o pkg/thsice:
781      - add a warning when used with pkg/aim but without updating SST
782        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
783    o pkg/offline:
784      - change where Offline-Fields are loaded, from load_fields_driver.F to
785        directly within FORWARD_STEP, just after updating iter number and time;
786      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
787        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
788       These changes allow:
789        a) to recover exactly on-line results using deltaToffline=deltaTClock,
790        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
791        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
792        time-step, both with GM & KPP files and with recomputing these fields;
793        b) no needs to switch on staggerTimeStep anymore;
794        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
795      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
796    o pkg/offline:
797      - change (rarely used) offset-iteration parameter to an offset time (in s):
798        can easily recover previous offset-iter effect by setting offset-time
799        (offlineTimeOffset) to offset-iter x deltaToffline;
800      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
801        in KPP as part of surface buoyancy forcing) in offline run.
802      - fix ptracers KPP non-local term in the case where KPP is re-computed.
803    o OpenAD
804      - Adding preliminary ggl90 test to OpenAD verification.
805        Config. with ggl90 currently diverges after 64 time steps
806        so will need more work to become more stable
807      - Adding preliminary kpp test to OpenAD verification.
808        required small tweakes in kpp_routines.F
809      - Merge and update from Krishna Narayanan's contrib area:
810        * Add one variable for preliminary OpenAD DIVA
811        * Add replacement time-stepping for OpenAD DIVA
812        * genmake2 flag -diva (but only for OpenAD; preliminary)
813        * required modifs for OAD_support
814        successful preliminary test for tutorial_global_oce_biogeo/
815    o pkg/seaice:
816      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
817      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
818        delta with a smooth function in s/r seaice_calc_viscosity
819        (no effect on EVP)
820      - rename local suffix "sqr" into "sq" for more consistent variable names
821    o pkg/seaice:
822        add new parameter SEAICE_deltaMin that is used ***only***
823        for regularizing Delta (and nothing else, like the parameter
824        which is also used for all sorts of things SEAICE_EPS).
825        Defaults to SEAICE_EPS for backward compatibility only.
826    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
827        the wrong key by inialising it before use -> fixes a recomputation
828        problem but does not fix the gradient
829    o pkg/layers:
830      - move resetting of flux arrays to outside the iLa loop
831        (this caused layers_diapycnal to not work with more than one layer coord.)
832      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
833    o pkg/layers:
834      - remove from common block 3D layers fields (used to diagnose transport
835        in tracer coords) and declare them as local arrays in layers_calc.F
836    o pkg/seaice:
837      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
838        in lab_sea forward experiment (changes results -> updated)
839      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
840    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
841       computations; for SEAICE_VECTORIZE_LSR
842      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
843        sweep to the outside,
844      - remove store directives and add "CADJ loop sequential" directives
845        in analogy to model/src/solve_tridiagonal.F
846      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
847        boundaries to yield more readable code. This has also the charming side
848        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
849        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
850        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
851        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
852        an additional option)
853       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
854       but the adjoint gradients (which are affected by this change) still explode.
855    o coupler (atm & ocn _compon_interf):
856      - avoid using Exch2 IO mapping if not suitable.
857    
858    checkpoint65m (2015/06/15)
859    o pkg/layers:
860      - clean-up old parameters setting (from Sep 2012):
861        + remove old parameters setting from common block (declared locally);
862        + stop if any old parameter is mixed with new parameters;
863        + check for valid or consistent parameter setting (e.g., layers_name)
864      - check that layers_bounds for Pot.Density are in the right range;
865        this is supposed to catch un-updated setting after recently shifting
866        potential density field "prho" by -1000 (now in "sigma" scale).
867    o pkg/layers:
868      - Added missing call to layers_fill for keeping track of tottend in
869        pkg/diagnostics/diagnostics_fill_state.F
870    o pkg/layers:
871      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
872        of diapycnal fluxes
873    o pkg/layers:
874      - reverted changes to interpolation to previous treatment; there
875        was never actually a problem
876    o pkg/layers:
877      - fix interpolation of layers tracers in the presence of partial cells
878      - add lots of new functionality to compute water mass transformation
879        (enabled by CPP flag LAYERS_THERMODYNAMICS)
880      - add new calls from main code (diags_oceanic_surf_flux.F,
881        thermodynamics.F, impldiff.F) and gad to save the necessary fields
882        for layers_thermodynamics calculations
883    o pkg/ptracers:
884      - add capability of stepping a passive tracer forward without advection
885        by setting PTRACERS_advScheme to 0.
886    o pkg/diagnostics:
887      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
888    o pkg/layers:
889      - shift potential density field "prho" by -1000 for density layer averaging so
890        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
891        Note that density bin boundaries (layers_bounds in data.layers) have
892        to be set accordingly (i.e., shifted, in sigma scale).
893    o pkg/layers:
894      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
895      - fix calculation of layer non-weighted velocity and layer probability
896      - add diagnostics for pot.density used for layer averaging
897    o pkg/seaice:
898      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
899        positiveness, modify a few comments and improve variable names,
900      - the changed computation of deltaC affects most seaice-related
901        experiments at the truncation level.
902        seaice_itd.thermo is affected by far the most, with
903        only 7 digits of agreement remaining; update experiments.
904    
905    checkpoint65l (2015/05/04)
906    o pkg/shelfice:
907      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
908        factor drKp1 to zero where it is negative (ie. do not use
909        SHELFICEBoundaryLayer if hFacC>1)
910      - the same for factor drLoc in shelfice_forcing.F
911    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
912        with modules in ptracers, when using testreport option "-small_f"
913    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
914      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
915    o verification/testreport
916      - add new option -small_f
917        with this option testreport first makes the target small_f (*.f files)
918        before running make (all). This is useful for explicit inlining when
919        all sources need to be full available.
920    o pkg/exf/exf_interp.F:
921        remove previous changes related to reverse (decreasing) input grids latitude
922    
923    checkpoint65k (2015/04/01)
924    o pkg/ecco:
925        fix missing cosphi initialization; use eccoiter in place of optimcycle;
926        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
927        instead of active read/write
928    o pkg/ctrl:
929        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
930        instead of active read/write.
931    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
932        return if .NOT.useAUTODIFF
933    o pkg/seaice: add CPP brackets (cost function related).
934    o model/src:
935        add useAUTODIFF run time switch.
936    o pkg/exf/exf_interp.F:
937        add code to allow input grids with latitude starting in the north (i.e. when
938        j=1 corresponds to northern edge of field); modify global_with_exf to test
939        this feature.
940    o verification/testreport:
941      - replace "grep -A3" with POSIX conformal sed command, because there are
942        implementations of grep that cannot do contextual searches
943      - replace "cat -n" by "nl" (two occurrences), because not all implementations
944        of "cat" have the option "-n"
945    o model/src:
946        add new file gsw_teos10.F that contains 3 functions, more or less a copy
947        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
948        convert from conservative to potential temperature. For now they are not
949        called anywhere.
950    o pkg/ggl90: make "useIDEMIX" useful
951      - re-organize code in s/r ggl90_calc a little to move computations that
952        are different for idemix into separate loops (changes verification
953        experiment idemix at truncation level, 12 digits remain -> updated)
954      - requires 2 new 2D fields KappaM, verticalShear
955      - make hFacI and recip_hFacI local 3D variables that are passed to
956        s/r ggl90_idemix
957      - fix and improve some comments
958    
959    checkpoint65j (2015/02/25)
960    o pkg/openad
961      - synchronize seawater.F with version in model/src: replace routine
962        body of sw_temp by calling sw_ptmp and fix/add a few comments.
963    o pkg/mnc:
964      - change default value of pickup_read/write_mnc params to FALSE
965        (since few features are missing in reading MNC pickup files).
966    o model/src:
967      - change default (background) vertical diffusivity for salt to be the
968        temperature (background) vertical diffusivity.
969      - change background vertical diffusivity in vertical mixing pkgs ggl90,
970        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
971        This makes ptracers default diffusivity (that uses salt diffKr) more
972        consistent with vertical mixing schemes.
973    o verification/testreport:
974      - fix typo in "-pcls" option ;
975      - put temp files in /tmp (instead of in local dir)
976      - add option "-ncad" to use genmake2 new option "-nocat4ad"
977      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
978    o pkg/ggl90 (idemix code):
979      - apply few fixes ; add some missing "_d 0" ; update output of exp.
980        global_ocean.90x40x15.idemix
981    o OpenAD
982      - enable active file I/O and begin removal of work-around code
983        for OpenAD for handling control variables (memory vs. active files)
984      - new CPP options file OPENAD_OPTIONS.h
985      - revert to genarr2d gradient check for hs94.1x64x5
986      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
987      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
988    o tools/genmake2:
989      - add option for an alternative Makefile (from Martin) where multiple
990        source files are sent to TAF (instead of all in one file).
991    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
992      - code provided by Carsten Eden as an extension of ggl90
993      - so far the code is turned on within ggl90 by setting a CPP-flag at
994        compile time; a runtime flag implementation is not yet complete
995      - tested in new verification experiment global_ocean.90x40x15.idemix
996    o verification:
997      - reduce length of the AD test run by half for experiments
998        global_ocean.cs32x15 (std + thsice) and isomip
999      - enable active file I/O for OpenAD, adjust verifications accordingly
1000      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1001    o verification/testreport:
1002      - fix two non-POSIX sed statements so that there are no error messages
1003        on Mac OS X
1004      - replace hostname -s with hostname | sed 's/\..*$//'
1005    o model/src/seawater.F:
1006      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1007        (following the matlab code), which would have avoided the bug caught
1008        by Matt (see below) in the first place
1009    o pkg/shelfice:
1010      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1011        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1012      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1013        ice-shelf case (i.e., within surface level).
1014      - add config summary in shelfice_check.F
1015      - remove global variable recip_SHELFICElatentHeat and replace by a local
1016        variable recip_latentHeat
1017      - introduce diagnostics for friction velocity uStar (in case of
1018        SHELFICEuseGammaFrict)
1019      - change verification experiment isomip.htd:
1020        + start from pickup (as input_ad at nIter0=8640)
1021        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1022        + test SHELFICEuseGammaFrict = .TRUE.
1023        + test SHELFICEadvDiffHeatFlux = .TRUE.
1024    o model/src:
1025      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1026        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1027        update output of experiments global_with_exf.yearly and isomip (all 6).
1028    o pkg/shelfice:
1029      - change setting of kTopC to also be zero where there is no ice-shelf.
1030      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1031        ice-shelf is.
1032      - first attempt to get RealFreshWaterFlux effects: for now, only without
1033        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1034    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1035      for thermodynamic calculations
1036      - because of divisions of the type 7/7 not exactly equal to 1, this change
1037        affects results of some verification experiments by up to 4 digits:
1038        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1039        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1040        adjoint: lab_sea, lab_sea.noseaicedyn
1041        -> updated
1042    
1043    checkpoint65i (2015/01/23)
1044    o model/src:
1045      - change units of frictionHeating field from W to W/m^2
1046      - fix bug in frictional heating from stratospheric drag in
1047        S/R ATM_PHYS_TENDENCY_APPLY_V
1048      - with synchronous time-stepping: move resetting to zero of frictionHeating
1049        field from load_fields_driver.F to thermodynamics.F ;
1050      - add diagnostics for frictional heating.
1051    o model/src & gmredi K3D:
1052      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1053      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1054      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1055        and name in pickup file).
1056      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1057    o model/src:
1058      - move (from ini_forcing.F) initialisation of all arrays in header file
1059        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1060        (since Nov 2012) with option selectAddFluid=1.
1061    o pkg/shelfice:
1062      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1063      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1064    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1065    o pkg/seaice: two new runtime parameters:
1066      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1067        long overdue
1068      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1069        parameterization of tensil stress for fast ice (does not do anything yet)
1070    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1071        for LSR: move checking overlaps out of JFNK-if-block
1072    o pkg/atm_phys:
1073      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1074        new S/R ATM_PHYS_DYN2PHYS.
1075      - fix level height for Linear Free-Surf case (to be consistent with
1076        fixed-in-time pressure levels).
1077    o pkg/mom_common (bottomdrag):
1078      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1079        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1080        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1081    o pkg/shelfice (u/v_drag):
1082      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1083      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1084        (now similar to shelfice_u_drag.F)
1085      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1086        from mom_vecinv.F (similar to mom_fluxform calls).
1087    o pkg/mom_common (bottomdrag):
1088      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1089      - add options for alternative discretisation of velocity norm in quadratic
1090        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1091        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1092        improves when averaging only the other component (e.g. vVel for U bottom
1093        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1094      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1095        friction (no-slip BC) thus getting the true distance from the bottom;
1096        off by default since this also reduces model stability (explicit bottom
1097        friction). Changes produce different machine truncation with linear-drag
1098        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1099        front_relax (bvp & mxl, 10 & 11 digits).
1100    o model/src & mom pkgs:
1101      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1102        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1103      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1104        just copy level Nr value to level Nr+1.
1105    o doc:
1106      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1107    o pkg/shelfice:
1108      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1109        SHELFICE.h: move array shelficemass to init_varia, initialise
1110        from array shelficemassinit, which is set in init_fixed and
1111        has option to be set from file; introduce array
1112        shelficeMassDynTend array, set thru file in init_fixed
1113      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1114        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1115        pkg/streamice
1116      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1117        SHELFICEMassStepping = .true.
1118      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1119    
1120    checkpoint65h (2014/12/17)
1121    o verification/global_ocean.90x40x15, global_ocean_ebm:
1122      - update to generic controls.
1123    o pkg/ctrl:
1124      - ctrl_map_ini_genarr.F: test for igen>0
1125      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1126      - move gentim2d part of ctrl_map_ini_genarr.F to
1127        new separate routine : ctrl_map_ini_gentim2d.F
1128      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1129        add time variable weights and cyclic controls (time mean,
1130        seasonal cycle, etc) capabilities to gentim2d
1131    o pkg/ecco:
1132      - move reading of error, conversion to weights from
1133        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1134    o global_oce_llc90, cs32:
1135      - activte sbo.
1136      - CTRL_SIZE.h : add maxCtrlProc.
1137      - activate the new genctrl capabilities.
1138      - update following reorganization of global_oce_input_fields.tar.gz  
1139    o pkg/ctrl/ctrl_ad_diff.list:
1140      - add missing ctrl_init_rec.f
1141    o tools/OAD_support/keepOriginal:
1142      - add ctrl_init_rec.F
1143    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1144      - avoid recomputations of xx_gentim2d_dummy.
1145    o momentum diagnostics:
1146      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1147        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1148    o pkg/seaice/seaice_lsr.F:
1149      - fix computation of BU/BV, make sure they are non-zero, only necessary
1150        for cubed sphere exchanges and SEAICE_OLx/y>0.
1151        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1152    o verification/global_ocean.cs32x15/input.seaice
1153      - add test for strong implicit coupling and restricted addtive Schwarz
1154        methods for LSR
1155      - update results/output.seaice.txt
1156    o verification/tutorial_global_oce_biogeo:
1157      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1158        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1159        update output_adm,_oadm,_tlm.txt
1160    o pkg/dic:
1161      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1162      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1163        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1164    o verification/tutorial_global_oce_biogeo:
1165      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1166        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1167        update output_adm,_oadm,_tlm.txt
1168    o eesupp/src:
1169      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1170        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1171    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1172      LSR (following Hutchings et al. 2004)
1173      - introduce zetaZ as a global variable (requires adjustments in
1174        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1175        in seaice_calc_viscosities.F
1176      - new flag SEAICEuseStrImpCpl (default off)
1177      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1178        momentum equations
1179      - JFNK-solver (preconditioner) adjusted to allow using this method
1180        (where it does not have any positive effect)
1181    o pkg/seaice
1182      - add overlap for restrictive additive Schwartz method also to LSR, but
1183        turn it off by default (because it only seems to work for non-cubed
1184        sphere/llc topologies)
1185    o pkg/autodiff
1186      - add extra exchanges in addummy_in_steppging also for mnc output
1187    o pkg/seaice:
1188      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1189        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1190    o pkg/obcs:
1191      - add option to specify domain-connected piece Id along OB though files
1192        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1193      - modify obcs_diag_balance.F to process each connected-part separately;
1194        exclude OB where Id = 0 but keep the full divergence there (-> constant
1195        Psi along this portion of OB and all inflow derived from grad(Phi))
1196      - add example of OB-conect files in verification/so_box_biogeo/input.
1197    o pkg/diagnostics:
1198      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1199      a) use non zero matrix element across OB and solve for Phi 1 grid point
1200         outside OB (i.e, where tracer OBCS are applied).
1201      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1202         velocity across OB, spread it uniformly along the OB in the RHS.
1203    
1204    checkpoint65g (2014/11/19)
1205    o pkg/diagnostcis:
1206      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1207    o pkg/my82,pp81,kl10:
1208      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1209        field diffKr as background diffusivity to set minimum diffusivity value.
1210    o pkg/seaice:
1211      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1212        Bouillon et al 2013)
1213      - add SEAICE_evpAlpha/Beta to namelist
1214      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1215        involve trivial re-ordering of divisions/multiplications that should not
1216        have any effects, but ... they do change the results of lab_sea.hb87 so
1217        that only 2 digits of agreement remain, in line with the general
1218        instability/fragility of the evp-code. For now, I do not care and just
1219        update the verification experiment
1220    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1221      - remove xx_genarr2d_numsmooth etc
1222      - use xx_genarr2d_preproc etc instead
1223      - carry out smooth_correl2D at initialization stage rather than during
1224        time stepping.
1225      - get smoothOpNb from xx_gentim2d_preproc
1226    o global_oce_cs32 :
1227      - add test of generic ecco capabilities.
1228    o pkg/exf/exf_getsurfacefluxes.F :
1229      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1230    o pkg/ctrl,ecco :
1231      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1232        is defined.
1233    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1234    o model/src:
1235      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1236        diffusivity (background) is specified but ignored.
1237    o verification:
1238      - in testreport, convert hostname to lower case for default output dir name
1239    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1240    o pkg/dic: add modifications from Hajoon:
1241      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1242      - light attenuation: add self-shading effect by climatological Chlorophyll
1243        (read from file).
1244    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1245        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1246    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1247        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1248        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1249        approach where CPP_OPTIONS.h includes an omnipotent
1250        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1251    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1252        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1253  o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF  o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
