5      ==============================      ==============================
6    
7    o pkg/bling
8      - Bug fix in bling_production regarding unit conversion for diagnostics
9        being put in the wrong place
10    o model/src:
11      - add back recomputation of rSurfW & S to ensure consistent column thickness
12        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
13        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
14        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
15    o pkg/autodiff:
16      - clean-up "checkpoint.flow"
17    o pkg/rw (Contribution from Jody Klymak):
18        option to set mds file suffix as function of time in simulation:
19        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
20           to select file suffix format; by default (=0), use iteration number;
21        *) add simple routine to return file suffix according to rwSuffixType;
22        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
23           use new S/R to get file suffix, except for debug output file (diagFreq)
24           and pkgs offline & rbcs input files.
25    o pkg/rw:
26      - uniform processing of "I10" suffix across writing fld routines; used to
27        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
28        (similar to cg3d.F, cg3d_ex0.F)
29    o pkg/mom_vecinv:
30      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
31        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
32    o pkg/bling:
33      - Many small changes intended to clean the code.
34        Unnecessary ADJOINT_SAFEs removed ;
35        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
36        diagnostics added.
37    
38    checkpoint66e (2017/03/14)
39    o pkg/exf:
40      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
41        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
42        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
43        avoid any dynamic allocation ;
44      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
45        read-in ; add warning when file is read-in but not used within pkg/exf ;
46        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
47      - update exf_summary.F (print {FLD}RepCycle).
48    o verification/global_with_exf:
49      - switch on exf interpolation in AD test (just like the forward test)
50    o pkg/mom_vecinv:
51      - add storage directives to avoid recomputations within mom_vecinv.F
52        which were generating seg. fault with gfortran -devel
53    o pkg/ctrl, pkg/smooth:
54      - initialize array halos which were generating seg. fault with
55        gfortran -devel in adjoint mode
56    o pkg/exf:
57      - for each input field, enable to specify a field specific repeat-cycle
58        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
59    o verification/lab_sea:
60      - update AD results of primary test and noseaicedyn test after switching
61        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
62        check stays about the same.
63    o pkg/exf:
64      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
65      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
66    o pkg/bling, USE_EXFCO2 code:
67      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
68      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
69    o pkg/exf:
70      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
71      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
72        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
73        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
74      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
75        EXF_INIT_FLD) and update calls in exf_init_varia.F
76      - For now, for backward compatibility, keep a simplified version of S/Rs
77        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
78      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
79        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
80    o tools/genmake2:
81      - replace "bc -l" (only used once) by "expr" (already used).
82    o verification/global_ocean.cs32x15:
83      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
84        Note: exf setting (data.exf) can be compared to other exf secondary exp
85        "seaice" (kept with useCAL=T) which has same time dependent forcing.
86    
87    checkpoint66d (2017/02/13)
88    o pkg/exf:
89      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
90        early on (in packages_boot.F) to stress this change in pkg setting.
91      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
92    o model/src:
93      - move call to ecco_phys to end of time step; this may induce minor
94        cost function changes by shifting time averages by one time step
95        for some variables; this revision resulted in changed adjoint results
96        in MITgcm_contrib/verification_other/global_oce_cs32
97    o pkg/exf:
98      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
99        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
100        e.g. precip, are not available.
101    o pkg/flt:
102      - flt_init_varia.F: use pickupSuff if specified
103      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
104        intermediate, step towards completing pkg/exch2 support within pkg/flt;
105        ifdef DEVEL_FLT_EXCH2 then:
106        - flt_init_fixed.F: comment out stop
107        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
108        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
109        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
110        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
111    o tools/genmake2 & pkg/pkg_depend:
112      - define new type of pkg dependency rule ("=pkg_x"), less strict than
113        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
114        (-pkg_x in packages.conf).
115      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
116      - add "+cal" to dependency list of pkg/ecco (needed to compile).
117      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
118    o utils/matlab:
119      - adding ocean_basin routines for defining basin masks.
120    o pkg/exf:
121      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
122        arguments, allowing to check (and stop) if parameter setting of
123         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
124        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
125        for backward compatibility.
126      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
127        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
128    o pkg/bling (USE_EXFCO2 code):
129      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
130        by adding a call to S/R EXF_GETFFIELD_START.
131    o pkg/exf:
132      - allows to compile without pkg/cal (but disabled by current dependency
133        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
134        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
135        of {FLD}startdate1 & date2 ; consistency check not yet coded.
136    o verification/global_ocean.cs32x15:
137      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
138        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
139    o pkg/exf:
140      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
141        calculations); change FWD experiment global_ocean.cs32x15
142        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
143    o pkg/exf:
144      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
145         {FIELD}startdate to {FIELD}StartTime
146        Note: new name also fit better the content, i.e, a start time in second.
147    o eesupp/src:
148      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
149    o pkg/exf:
150      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
151        to allow to read-in Sensible & Latent Heat flux ;
152      - simplify pkg/exf main options:
153        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
154           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
155           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
156        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
157           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
158        3) improve options documentation in EXF_OPTIONS.h.
159    o pkg/ecco:
160      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
161        ecco_summary.F: add passive tracer cost functions to gencost;
162        m_ptracer and m_boxmean_ptracer
163    o pkg/ctrl:
164      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
165        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
166        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
167        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
168    o model/src:
169      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
170        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
171    o pkg/exf:
172      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
173        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
174    
175    checkpoint66c (2017/01/19)
176    o verification:
177      - add new option "-src" to testreport to only produce source code (*.f),
178        including taf output src code (if using '-adm'/'-tlm' option).
179    o pkg/exf:
180      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
181    o pkg/diagnostics:
182      - add run-time variable diagMdsDir to specify a subdirectory for
183        diagnostic output when mds is being used and mdsioLocalDir is not.
184    o pkg/mnc:
185      - mnc_utils.F: edit stop message
186    o pkg/autodiff:
187      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
188        add HAVE_SYSTEM bracket around system call to mkdir
189    o pkg/profiles:
190      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
191        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
192      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
193        add HAVE_SYSTEM bracket around system call to mkdir
194    o pkg/smooth:
195      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
196      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
197      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
198    o pkg/exf:
199      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
200        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
201        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
202      - summary: skip detailed field report if not used (empty file-name).
203    o tools/xmakedepend:
204      - In case line editor "ed" is missing, switch to "sed" command to clean-up
205        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
206    o pkg/exf:
207      - change definition of "hflux" input file to always include Short-Wave;
208        this is now consistent with hflux computation (if using bulk-formulae)
209        and hflux diagnostic & documentation (in EXF_FIELDS.h).
210    
211    checkpoint66b (2016/12/01)
212    o model & momentum pkgs:
213      - implement fully implicit bottom friction combined with implicit surf.
214        pressure, for now, only in hydrostic formulation:
215        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
216          and run with selectImplicitDrag=2 ;
217        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
218      - partial implicit time-stepping (bot. friction + vert. visc first, then
219        surf. press) corresponding to selectImplicitDrag=1 should be applicable
220        to NH formulation but not available until we solve for surf. pressure
221        increment (instead of full etaN).
222      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
223        with implicit vertical viscosity.
224    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
225      - this is a first version that includes many regularisations that may
226        not all be necessary, to be sorted out,
227      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
228      - change one verification experiment in seaice_itd to use and test new code
229      - seaice_growth: catch a case where the argument of log can be zero
230        or smaller (important for code stability)
231    o model/src:
232      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
233        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
234        similar A.X'=Y' system (with same matrix A) in subsequent calls;
235        switch based on errCode (In/Out) argument value; in calling routines,
236        initialise errCode before first call.
237    
238    checkpoint66a (2016/10/18)
239    o pkg/bling:
240      - BLING package now loads in atmospheric pCO2 file using exf package routines
241        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
242    o model/src & pkg/ptracers:
243      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
244        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
245        implicitDiffusion (respectively) are used (even without momImplVertAdv
246        or temp,salt,PTRACERS_ImplVertAdv).
247    o model/src & generic_advdiff:
248      - add parenthesis in main diagonal calculation of implicit vertical
249        diffusion matrix (impldiff.F & gad_implicit_r.F).
250        This affects results at machine truncation level; update output of many
251        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
252    o pkg/mom_commom & generic_advdiff:
253      - add deep atmosphere and anelastic scaling factor in implicit vertical
254        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
255    o model/src:
256      - remove few unnecessary temp array copies in solve_tridiagonal.F
257        & solve_pentadiagonal.F
258    
259    checkpoint65z (2016/09/28)
260    o pkg/seaice: fix multithreading for seaice_fgmres.F
261      - remove unecessary variables from common blocks
262      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
263        basis, that are stored in commom blocks (including integer variable i1)
264      - clean up code a little by removing commented lines that refer to
265        original code
266      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
267    o MITgcm manual:
268      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
269        preliminary documentation for generic controls (8.3; ctrl.tex),
270        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
271        ecco_costfunction.tex
272    o pkg/ecco:
273      - update and cleanup list of CCP options
274      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
275        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
276      - add checks that retired run-time options are not used, and in relation
277        to gencost_mask and gencost_errfile
278      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
279        gencost_nrecperiod
280      - fix m_eta computation for virtual salt flux case
281      - add m_horflux_vol case (selected via gencost_barfile) that computes
282        transports via cost_gencost_boxmean (gencost_flag=-3)
283      - use gencost_flag more systematically (i.e., avoid using gencost_name)
284        for code switches (aside from physical variable selection)
285    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
286      attempt appears to be a bit of a hack and my need some repair down the road
287    o pkg/exf:
288      - interpolation near South Pole: fix criteria on input field latitude.
289    o pkg/icefront & pkg/exf:
290      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
291        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
292    o pkg/exf:
293      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
294        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
295        (add suffix "_out" instead of a prefix); keep same record number as in
296        input file but always write record 1 first (to avoid a STOP in I/O S/R).
297        Change output file content by writing interpolated field before applying
298        land-sea mask (helpful for debug).
299      - 2 compon. vector interpolation with rotation: apply scaling factor on
300        each compon. (Eastward and Northward) just before rotation.
301    o pkg/bling:
302      - Cleaned package. Removed not needed code and comments.
303      - adjoint example now works
304        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
305    o pkg/ptracers:
306      - add Bruno Deremble's code to complete the linear surface correction
307        for tracer conservation;
308      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
309    
310    checkpoint65y (2016/07/29)
311    o pkg/debug (stats):
312      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
313        proc/thread mapping);
314      - fix Min & Max for case where 1 thread has only empty tiles;
315      - use RL variable to count number of wet grid points (with big domain,
316        can be too large to fit into integer*4).
317    o pkg/monitor:
318      - use RL variable to count number of wet grid points (but used only for del2)
319      - add new routine to compute Advective CFL within tracer time-stepping with
320        writing delayed until next monitor output.
321    o pkg/obcs:
322      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
323    o pkg/cal:
324      - calandar-dump: treat case myTime < timePhase in the same way as in
325        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
326    o pkg/dic & seaice:
327      - fix compilation of ocean component for coupled atm+ocn model with
328        seaice dynamics & dic.
329    
330    checkpoint65x (2016/06/11)
331    o add a license text file in main MITgcm tree.
332    o added pkg/bling:
333      - intermediate complexity biogeochemical model
334      - see bling_description.txt for details
335      - verification experiment is global_oce_biogeo_bling (for now, in
336        Contrib/verification_other/); tested daily on baudelaire with gfortran.
337      - add entry point in pkg/gchem for new pkg "bling".
338    o pkg/seaice: fix tensile stength computation
339      - replace global field tensileStrength by tensileStrFac
340      - tensileStrFac can be computed once in S/R seaice_init_varia
341      - fortunately that does not affect any verification results
342    
343    checkpoint65w (2016/05/12)
344    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
345         with ECCO_CTRL_DEPRECATED defined
346    o verification/global_ocean.cs32x15:
347      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
348        with "selectNHfreeSurf=1".
349    o model/src (non-hydrostatic free-surface):
350      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
351        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
352      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
353        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
354        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
355        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
356      - Update output (changes at machine truncation level) of verification exp:
357        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
358        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
359    o pkg/seaice: ITD code
360      - fix picking up from a single category model by initialising
361        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
362      - split a long warning message in seaice_check_pickup.F into two lines,
363        because NEC SX-ACE cannot deal with the long line.
364    o model/src:
365      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
366    o pkg/seaice:
367      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
368    o pkg/seaice:
369      - add basal stress as parameterisation for grounding ice
370        following Lemieux et al. (2015)
371      - turn on by setting new parameter SEAICEbasalDragK2 to a value
372        larger than 0. Lemieux et al. (2015) recommend 15.
373      - The adjoint complains with extra recomputations so there is also a
374        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
375        order to postpone the problem
376      - compile the new code in lab_sea
377    o verification/halfpipe_streamice:
378      - update both TAF and OpenAD adm output (machine truncation differences)
379    
380    checkpoint65v (2016/04/08)
381    o verification/advect_xz:
382      - increase overlap size from 3 to 4 and add new secondary test for PQM
383        advection scheme (with mono & wino limiter).
384      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
385    o model/src:
386      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
387        added phi0Ref) to set vertical axis origin and phiRef origin;
388        keep Ro_SeaLevel for backward compatibility (with a warning).
389       According to coordinate and fluid type:
390        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
391        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
392        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
393        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
394      - remove Ro_SeaLevel from ATM experiment parameter files;
395      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
396        complement; update output.txt (changes at machine truncation level).
397    o pkg/seaice/seaice_evp.F
398      - simplify computation of deltaZ and zetaZ to simple averaging following
399        Bouillon et al. (2013). This removes a lot of code, but also changes
400        verification experiment lab_sea.hb87 -> updated
401    
402    checkpoint65u (2016/03/14)
403    o pkg/generic_advdiff:
404      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
405        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
406        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
407        testing and not for actual use.
408    o model/src:
409      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
410        origin r = rF(1);
411      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
412        in EOS for height coordinate: enable to include NH Pressure or to use
413        more accurate pressure vertical profile; options not linked to EOS type
414        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
415      - start to implement variable gravity (along vertical): for now, only with
416        z-coords (not even z*).
417      - add Ideal Gas equation of state for height coordinate.
418      - update OpenAD output (affected at machine truncation level) of exp:
419        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
420    o pkg/exf:
421      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
422        of exf interpolation (before any rescaling, rotation or interpolation
423        to velocity point) for each field that gets loaded from file. This option
424        identically mimics the input file organization (e.g. record numbers in year
425        by year input files) besides the change in horizontal grid.
426      - add rotateStressOnAgrid run-time switch so that wind stress fields
427        can be provided on the A-grid in zonal/meridional direction and
428        rotated on the fly. This only applies to the case when the exf
429        interpolation is off and rotateStressOnAgrid is false by default.
430    o model/src:
431      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
432        it's also used with pkg/atm_phys) and add few more parameters (but still
433        inactive, src code yet to come)
434    
435    checkpoint65t (2016/02/10)
436    o pkg/atm_phys:
437      - from Ruth Geen: add optical depth dependence on CO2 concentration.
438    o model/src:
439      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
440        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
441        Update output of exp. deep_anelastic (changes at truncation level).
442    o tools:
443      - add a hack in "remove_comments_sed" (used only with TAF) for recent
444        version of OpenMPI (shipped with FC.23): comment out the new header
445        file "mpif-sizeof.h" which causes problems to TAF.
446    o pkg/seaice:
447      - change the termination criterion so that maxits (SEAICElinearIterMax)
448        has an effect
449      - unify iteration parameters for implicit solvers (JFNK and Picard)
450        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
451        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
452        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
453        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
454        SEAICEnonLinTol     replaces JFNKgamma_nonlin
455      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
456      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
457        use with SEAICEuseKrylov
458    o pkg/seaice/seaice_lsr.F
459        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
460        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
461        an effect.
462    o pkg/seaice: add two new parameters
463      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
464        parameter is not in any namelist)
465      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
466        a preconditioner for the non-linear Newton iteration of the JFNK
467        solver
468    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
469      affects some experiments at truncation level:
470      - global_ocean.cs32x15.icedyn (11 digits),
471      - global_ocean.cs32x15.seaice (11 digits),
472      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
473      - also update global_ocean.cs32x15 adjoint and tangent-linear results
474    o pkg/salt_plume & pkg/thsice:
475      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
476        connect salt_plume flux to ATM-OCN coupling pkgs interface:
477       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
478         export to coupler interface) even without compiling pkg/salt_plume ;
479       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
480         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
481    o pkg/dic:
482      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
483        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
484        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
485      - move also update with values from ATM-OCN Coupler in the same new S/R
486        (previously done in ocn_apply_import.F).
487    o tools/adjoint_options:
488      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
489        has been changed on Jan 14, 2016.
490    o pkg/ggl90:
491      - add alternative discretisation of vertical shear (off by default), to
492        compute the mean (@ grid-cell center) of vertical shear compon instead of
493        vertical shear of mean flow (@ grid-cell center).
494      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
495        results on adjacent faces of cubed-sphere grids; this fix the restart.
496    o pkg/atm_compon_interf:
497      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
498        pass last value, stored directly before export to CPL ;
499        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
500      - remove atmSLPr from pickup files (no longer needed for restart)
501    
502    checkpoint65s (2016/01/13)
503    o eesupp & genmake2:
504       - first check for Function ETIME and, if it fails, then check for subroutine
505         ETIME and consistent output; use the appropriate version in timers.F
506    o model/src:
507      - to check restart test, add option to apply EXCH to U,V earlier, just before
508        integr_continuity; turned off by default.
509    o pkg/dic:
510      - remove CPP option USE_ATMOSCO2 (not needed)
511    o tools/tst_2+2:
512      - try to ignore difference between +0 and -0 in binary file, causing test
513        to fail for no good reason.
514    o eesupp & genmake2:
515      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
516        but also check (in genmake2) that test runs and returns meaningful results.
517    o coupler pkgs:
518      Finish implementation of optionally-exchanged variable switches (started on
519       Nov 12) with addition of few more exchanged fields, including 2-way exchange
520       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
521       advection in OCN component; this requires sequential coupling.
522      coupler (pkg/atm_ocn_coupler):
523      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
524        routines (useful for debug).
525      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
526         flux, DIC fields) if corresponding switch is ON.
527      - add option to export RunOff to OCN (to use for DIC river input)
528      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
529      components (pkg/atm_ & ocn_compon_interf):
530      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
531        optionally exchanged fields; add a check & stop in cpl_readparms.F.
532        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
533        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
534      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
535        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
536      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
537      - hold in common block coupler optionally-exchanged variable switch
538        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
539      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
540        this is intended to replace the OCN cplFldtave.* output files (not updated
541        to contain new additional exchanged fields).
542    o pkg/dic:
543      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
544    o pkg/thsice:
545      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
546        and writing of thsice pickup files.
547    o pkg/atm_compon_interf:
548      - move all field individual export-call out of cpl_export_import_data.F
549        into new S/R ATM_EXPORT_FIELDS
550    o pkg/atm_compon_interf:
551      - store state variables (for now, only thSIce fields) just before beeing
552        exported (in cpl_export_import_data.F, like on ocean side) instead of from
553        atm_store_my_data.F like all exported fluxes.
554      - new version of pickup_cpl: write field names into meta file and read meta
555        file to find field postion in pickup. Also only write/read fields meeded for
556        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
557    o pkg/dic:
558      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
559    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
560        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
561        value can be from domain [0,1] to average between the two methods
562    o pkg/atm_phys:
563      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
564        hold fixed in time).
565    
566    checkpoint65r (2015/12/21)
567    o pkg/seaice:
568        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
569        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
570    o pkg/seaice:
571      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
572        when SEAICEscaleSurfStress=.TRUE.,
573      - apply areaW and areaS in S/R seaice_calc_lhs
574    o pkg/atm_phys:
575      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
576        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
577        for individual contribution (convection, LSC cond, radiation)
578      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
579        information); activated with: solar_exponent=0. and wv_exponent=-1.
580    o pkg/ggl90:
581      - within IDEMIX add upper limit for horizontal group velocity to
582        avoid instability problems in the explicit horizontal diffusion term for
583        long time steps or high resolution
584    o pkg/diagnostics:
585      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
586        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
587    o testreport:
588      - remove "-v" (verbose option) in default mpirun command.
589    o pkg/seaice/seaice_growth:
590      - catch potential division by zero in ITD code, does not change
591        verification results
592    o pkg/ecco:
593      - retire old codes to the Attic. The calls to retired functions are
594        left in a commented form in case they ever need to be re-activated.
595      - ecco_check.F: issue warning if any old CPP option is
596        defined that corresponds to retired codes -- then stop.
597    o pkg/atm_compon_interf:
598      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
599        coupler: use last time-step value instead of average over cplSendFrq_iter
600        time-step, similar to what is done for seaIceMass.
601        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
602    o eesupp & genmake2:
603      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
604        <= remove until a fix is found for some ifort version on ia32 machine.
605    o pkg/seaice/seaice_evp:
606      - refine residual computation
607    
608    checkpoint65q (2015/11/18)
609    o pkg/seaice/seaice_evp:
610      - fix residual computations so that they no longer affect the actual
611        simulation code
612      - fix seaice_readparams to be able to actually set new parameters
613        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
614    o model/src:
615      - fix wrong truncation (single prec) from "FLOAT" function in expressions
616        like: deltaT*FLOAT(myIter) when myIter is large:
617         a) replaced by DFLOAT (if not seen by TAF);
618         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
619    o pkg/aim_v23:
620      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
621        when pickupSuff is set ; do write rolling pickups + at the end of the run.
622    o pkg/atm_ocn_coupler + ocn_compon_interf:
623      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
624        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
625        add corresponding call in DO_OCEANIC_PHYS.
626    o coupler pkgs:
627      Start a new way to set-up optionally-exchanged variables (previously, only
628       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
629       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
630       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
631       compononent param default can be set accordingly).
632      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
633       but rather applies to a group a fields (going both ways like for DIC)
634       and corresponds to an option of coupling config.
635      coupler (pkg/atm_ocn_coupler):
636      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
637        and read namelist directly (without eessup S/R calls) instead of
638        in the very un-flexible old way, 1 param per line, in fixed order;
639      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
640        cleanly in CPL_CHECK_CPLCONFIG
641      - add new coupling-exchange selectors (some not yet active) including
642        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
643                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
644      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
645        component ; called directly from coupler.F, after comp. registrations;
646      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
647         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
648          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
649      components (pkg/atm_ & ocn_compon_interf):
650      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
651        CPP header file in all pkg source files.
652      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
653        ATM/OCN_CHECK_CPLCONFIG;
654      - add error-counter to track errors (e.g., in "data.cpl") and to stop
655        cleanly in ATM/OCN_CHECK_CPLCONFIG;
656      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
657        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
658        before PACKAGES_READPARMS;
659      verification/cpl_aim+ocn/:
660      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
661        "data.cpl" for coupler (in input_cpl).
662    o eesupp/inc:
663      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
664        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
665        to always cumulate tile local-sum in the same order (still uses
666        MPI_Allreduce like standard code).
667      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
668        that are now identical to standard version (in eesupp/inc).
669    o pkg/shelfice:
670      - add SHELFICETransCoeffTFile for initializing spatially varying
671        heat and salt transfer coefficients
672    o pkg/atm_compon_interf & ocn_compon_interf:
673      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
674        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
675      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
676    o pkg/atm_ocn_coupler:
677      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
678    o pkg/rbcs:
679      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
680        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
681      - add a short report (to STDOUT) about RBCS-mask settings.
682    
683    checkpoint65p (2015/10/23)
684    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
685        there is no adjoint test for EVP, we don't know what it does to the adjoint
686        solution, but at least there are no more recomputation warnings left
687    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
688        a chance of giving the same results as a fully converged VP (JFNK) solver
689    o tools/adjoint_options/adjoint_diva:
690      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
691    o pkg/streamice:
692      - spotted bug in streamice_driving_stress using dyG where should have been dxG
693    o pkg/exf:
694      - remove STOP statement that prevented to use wind or (wind-)stress
695        interpolation for constant-in-time forcing fields (wind/stress period = 0).
696    o pkg/seaice:
697      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
698        5 additionals 2D fields and 6 new store directives
699      - change logic in seaice_readparms.F: EVP code can now be turned on in
700        various ways, setting SEAICE_deltaTev is no longer required,
701        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
702        or SEAICEaEVPcoeff
703    o pkg/shelfice/shelfice_thermodynamics.F
704      - redefining uLoc/vLoc to u/v, instead of 2u/v
705    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
706      - this is an intermediate state of a truely converging EVP that has
707        the potential of outperforming implicit VP methods, I do not recommend
708        using it yet.
709      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
710        and all parameters are hardwired
711      - for convergence it still requires very smooth regularisations, that means,
712        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
713        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
714        specific averaging appears to be required, still subject to tuning
715      - still needs cleaning and I need to turn parameter into runtime parameters
716      - add code to compute and print residuals of iteration, compile with
717        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
718    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
719      that entered with r1.54 on Sep04, 2015, -> update results
720    
721    checkpoint65o (2015/09/14)
722    o pkg/mom_vecinv & mom_common:
723      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
724        called from there.
725      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
726        allows to use Vector-Invariant form in deep atmos and anelastic formulation
727    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
728      and Koenig-Beatty+Holland (2012)
729      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
730      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
731      - requires an extra input argument for S/R seaice_calc_viscosities
732      - tensileStrength's depth dependence is different from Itkin et al. (2015)
733        (to be changed and played with, for now exponential)
734    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
735      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
736        by AREA according to Connelly et al. (2004), JPO.
737      - For EVP and the LSR solver, the implicit part of the drag term is
738        the only non-zero term in the denominator when there is no ice (which
739        prevented running the model with zero ice-ocean drag). If
740        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
741        (or zero main diagonals BU/BV) which need to be caught. A practical
742        consequence is that for open water, the momentum equation reduce
743        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
744        they happen to be zero, often leading to a non-zero solution over
745        open water.
746    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
747        efficient EVP method.
748      - introduce area-weighted averages for e12 (analogously to
749        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
750        remain, but also changing the order of terms in the previous average
751        changed the results as much) -> update experiment
752      - add SEAICE_DELTA_SMOOTHREG code
753      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
754        TEM-code
755      - adjust loop bounds so that only required fields are computed
756      - add new averaging code for zetaZ/deltaZ (again similar to
757        seaice_calc_viscosities.F), inactive by default for now (will change
758        results again), but will replace old code eventually
759    o eesupp/src:
760      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
761        to always cumulate tile local-sum in the same order
762        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
763        Still uses MPI_Allreduce (like standard code) but on array of tiles
764        and should be faster than GLOBAL_SUM_SEND_RECV code.
765      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
766        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
767      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
768         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
769         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
770         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
771         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
772    
773    checkpoint65n (2015/07/29)
774    o pkg/thsice:
775      - add a warning when used with pkg/aim but without updating SST
776        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
777    o pkg/offline:
778      - change where Offline-Fields are loaded, from load_fields_driver.F to
779        directly within FORWARD_STEP, just after updating iter number and time;
780      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
781        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
782       These changes allow:
783        a) to recover exactly on-line results using deltaToffline=deltaTClock,
784        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
785        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
786        time-step, both with GM & KPP files and with recomputing these fields;
787        b) no needs to switch on staggerTimeStep anymore;
788        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
789      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
790    o pkg/offline:
791      - change (rarely used) offset-iteration parameter to an offset time (in s):
792        can easily recover previous offset-iter effect by setting offset-time
793        (offlineTimeOffset) to offset-iter x deltaToffline;
794      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
795        in KPP as part of surface buoyancy forcing) in offline run.
796      - fix ptracers KPP non-local term in the case where KPP is re-computed.
797    o OpenAD
798      - Adding preliminary ggl90 test to OpenAD verification.
799        Config. with ggl90 currently diverges after 64 time steps
800        so will need more work to become more stable
801      - Adding preliminary kpp test to OpenAD verification.
802        required small tweakes in kpp_routines.F
803      - Merge and update from Krishna Narayanan's contrib area:
804        * Add one variable for preliminary OpenAD DIVA
805        * Add replacement time-stepping for OpenAD DIVA
806        * genmake2 flag -diva (but only for OpenAD; preliminary)
807        * required modifs for OAD_support
808        successful preliminary test for tutorial_global_oce_biogeo/
809    o pkg/seaice:
810      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
811      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
812        delta with a smooth function in s/r seaice_calc_viscosity
813        (no effect on EVP)
814      - rename local suffix "sqr" into "sq" for more consistent variable names
815    o pkg/seaice:
816        add new parameter SEAICE_deltaMin that is used ***only***
817        for regularizing Delta (and nothing else, like the parameter
818        which is also used for all sorts of things SEAICE_EPS).
819        Defaults to SEAICE_EPS for backward compatibility only.
820    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
821        the wrong key by inialising it before use -> fixes a recomputation
822        problem but does not fix the gradient
823    o pkg/layers:
824      - move resetting of flux arrays to outside the iLa loop
825        (this caused layers_diapycnal to not work with more than one layer coord.)
826      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
827    o pkg/layers:
828      - remove from common block 3D layers fields (used to diagnose transport
829        in tracer coords) and declare them as local arrays in layers_calc.F
830    o pkg/seaice:
831      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
832        in lab_sea forward experiment (changes results -> updated)
833      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
834    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
835       computations; for SEAICE_VECTORIZE_LSR
836      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
837        sweep to the outside,
838      - remove store directives and add "CADJ loop sequential" directives
839        in analogy to model/src/solve_tridiagonal.F
840      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
841        boundaries to yield more readable code. This has also the charming side
842        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
843        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
844        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
845        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
846        an additional option)
847       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
848       but the adjoint gradients (which are affected by this change) still explode.
849    o coupler (atm & ocn _compon_interf):
850      - avoid using Exch2 IO mapping if not suitable.
851    
852    checkpoint65m (2015/06/15)
853    o pkg/layers:
854      - clean-up old parameters setting (from Sep 2012):
855        + remove old parameters setting from common block (declared locally);
856        + stop if any old parameter is mixed with new parameters;
857        + check for valid or consistent parameter setting (e.g., layers_name)
858      - check that layers_bounds for Pot.Density are in the right range;
859        this is supposed to catch un-updated setting after recently shifting
860        potential density field "prho" by -1000 (now in "sigma" scale).
861    o pkg/layers:
862      - Added missing call to layers_fill for keeping track of tottend in
863        pkg/diagnostics/diagnostics_fill_state.F
864    o pkg/layers:
865      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
866        of diapycnal fluxes
867    o pkg/layers:
868      - reverted changes to interpolation to previous treatment; there
869        was never actually a problem
870    o pkg/layers:
871      - fix interpolation of layers tracers in the presence of partial cells
872      - add lots of new functionality to compute water mass transformation
873        (enabled by CPP flag LAYERS_THERMODYNAMICS)
874      - add new calls from main code (diags_oceanic_surf_flux.F,
875        thermodynamics.F, impldiff.F) and gad to save the necessary fields
876        for layers_thermodynamics calculations
877    o pkg/ptracers:
878      - add capability of stepping a passive tracer forward without advection
879        by setting PTRACERS_advScheme to 0.
880    o pkg/diagnostics:
881      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
882    o pkg/layers:
883      - shift potential density field "prho" by -1000 for density layer averaging so
884        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
885        Note that density bin boundaries (layers_bounds in data.layers) have
886        to be set accordingly (i.e., shifted, in sigma scale).
887    o pkg/layers:
888      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
889      - fix calculation of layer non-weighted velocity and layer probability
890      - add diagnostics for pot.density used for layer averaging
891    o pkg/seaice:
892      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
893        positiveness, modify a few comments and improve variable names,
894      - the changed computation of deltaC affects most seaice-related
895        experiments at the truncation level.
896        seaice_itd.thermo is affected by far the most, with
897        only 7 digits of agreement remaining; update experiments.
898    
899    checkpoint65l (2015/05/04)
900    o pkg/shelfice:
901      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
902        factor drKp1 to zero where it is negative (ie. do not use
903        SHELFICEBoundaryLayer if hFacC>1)
904      - the same for factor drLoc in shelfice_forcing.F
905    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
906        with modules in ptracers, when using testreport option "-small_f"
907    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
908      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
909    o verification/testreport
910      - add new option -small_f
911        with this option testreport first makes the target small_f (*.f files)
912        before running make (all). This is useful for explicit inlining when
913        all sources need to be full available.
914    o pkg/exf/exf_interp.F:
915        remove previous changes related to reverse (decreasing) input grids latitude
916    
917    checkpoint65k (2015/04/01)
918    o pkg/ecco:
919        fix missing cosphi initialization; use eccoiter in place of optimcycle;
920        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
921        instead of active read/write
922    o pkg/ctrl:
923        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
924        instead of active read/write.
925    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
926        return if .NOT.useAUTODIFF
927    o pkg/seaice: add CPP brackets (cost function related).
928    o model/src:
929        add useAUTODIFF run time switch.
930    o pkg/exf/exf_interp.F:
931        add code to allow input grids with latitude starting in the north (i.e. when
932        j=1 corresponds to northern edge of field); modify global_with_exf to test
933        this feature.
934    o verification/testreport:
935      - replace "grep -A3" with POSIX conformal sed command, because there are
936        implementations of grep that cannot do contextual searches
937      - replace "cat -n" by "nl" (two occurrences), because not all implementations
938        of "cat" have the option "-n"
939    o model/src:
940        add new file gsw_teos10.F that contains 3 functions, more or less a copy
941        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
942        convert from conservative to potential temperature. For now they are not
943        called anywhere.
944    o pkg/ggl90: make "useIDEMIX" useful
945      - re-organize code in s/r ggl90_calc a little to move computations that
946        are different for idemix into separate loops (changes verification
947        experiment idemix at truncation level, 12 digits remain -> updated)
948      - requires 2 new 2D fields KappaM, verticalShear
949      - make hFacI and recip_hFacI local 3D variables that are passed to
950        s/r ggl90_idemix
951      - fix and improve some comments
952    
953    checkpoint65j (2015/02/25)
954    o pkg/openad
955      - synchronize seawater.F with version in model/src: replace routine
956        body of sw_temp by calling sw_ptmp and fix/add a few comments.
957    o pkg/mnc:
958      - change default value of pickup_read/write_mnc params to FALSE
959        (since few features are missing in reading MNC pickup files).
960    o model/src:
961      - change default (background) vertical diffusivity for salt to be the
962        temperature (background) vertical diffusivity.
963      - change background vertical diffusivity in vertical mixing pkgs ggl90,
964        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
965        This makes ptracers default diffusivity (that uses salt diffKr) more
966        consistent with vertical mixing schemes.
967    o verification/testreport:
968      - fix typo in "-pcls" option ;
969      - put temp files in /tmp (instead of in local dir)
970      - add option "-ncad" to use genmake2 new option "-nocat4ad"
971      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
972    o pkg/ggl90 (idemix code):
973      - apply few fixes ; add some missing "_d 0" ; update output of exp.
974        global_ocean.90x40x15.idemix
975    o OpenAD
976      - enable active file I/O and begin removal of work-around code
977        for OpenAD for handling control variables (memory vs. active files)
978      - new CPP options file OPENAD_OPTIONS.h
979      - revert to genarr2d gradient check for hs94.1x64x5
980      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
981      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
982    o tools/genmake2:
983      - add option for an alternative Makefile (from Martin) where multiple
984        source files are sent to TAF (instead of all in one file).
985    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
986      - code provided by Carsten Eden as an extension of ggl90
987      - so far the code is turned on within ggl90 by setting a CPP-flag at
988        compile time; a runtime flag implementation is not yet complete
989      - tested in new verification experiment global_ocean.90x40x15.idemix
990    o verification:
991      - reduce length of the AD test run by half for experiments
992        global_ocean.cs32x15 (std + thsice) and isomip
993      - enable active file I/O for OpenAD, adjust verifications accordingly
994      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
995    o verification/testreport:
996      - fix two non-POSIX sed statements so that there are no error messages
997        on Mac OS X
998      - replace hostname -s with hostname | sed 's/\..*$//'
999    o model/src/seawater.F:
1000      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1001        (following the matlab code), which would have avoided the bug caught
1002        by Matt (see below) in the first place
1003    o pkg/shelfice:
1004      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1005        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1006      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1007        ice-shelf case (i.e., within surface level).
1008      - add config summary in shelfice_check.F
1009      - remove global variable recip_SHELFICElatentHeat and replace by a local
1010        variable recip_latentHeat
1011      - introduce diagnostics for friction velocity uStar (in case of
1012        SHELFICEuseGammaFrict)
1013      - change verification experiment isomip.htd:
1014        + start from pickup (as input_ad at nIter0=8640)
1015        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1016        + test SHELFICEuseGammaFrict = .TRUE.
1017        + test SHELFICEadvDiffHeatFlux = .TRUE.
1018    o model/src:
1019      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1020        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1021        update output of experiments global_with_exf.yearly and isomip (all 6).
1022    o pkg/shelfice:
1023      - change setting of kTopC to also be zero where there is no ice-shelf.
1024      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1025        ice-shelf is.
1026      - first attempt to get RealFreshWaterFlux effects: for now, only without
1027        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1028    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1029      for thermodynamic calculations
1030      - because of divisions of the type 7/7 not exactly equal to 1, this change
1031        affects results of some verification experiments by up to 4 digits:
1032        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1033        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1034        adjoint: lab_sea, lab_sea.noseaicedyn
1035        -> updated
1036    
1037    checkpoint65i (2015/01/23)
1038    o model/src:
1039      - change units of frictionHeating field from W to W/m^2
1040      - fix bug in frictional heating from stratospheric drag in
1041        S/R ATM_PHYS_TENDENCY_APPLY_V
1042      - with synchronous time-stepping: move resetting to zero of frictionHeating
1043        field from load_fields_driver.F to thermodynamics.F ;
1044      - add diagnostics for frictional heating.
1045    o model/src & gmredi K3D:
1046      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1047      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1048      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1049        and name in pickup file).
1050      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1051    o model/src:
1052      - move (from ini_forcing.F) initialisation of all arrays in header file
1053        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1054        (since Nov 2012) with option selectAddFluid=1.
1055    o pkg/shelfice:
1056      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1057      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1058    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1059    o pkg/seaice: two new runtime parameters:
1060      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1061        long overdue
1062      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1063        parameterization of tensil stress for fast ice (does not do anything yet)
1064    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1065        for LSR: move checking overlaps out of JFNK-if-block
1066    o pkg/atm_phys:
1067      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1068        new S/R ATM_PHYS_DYN2PHYS.
1069      - fix level height for Linear Free-Surf case (to be consistent with
1070        fixed-in-time pressure levels).
1071    o pkg/mom_common (bottomdrag):
1072      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1073        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1074        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1075    o pkg/shelfice (u/v_drag):
1076      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1077      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1078        (now similar to shelfice_u_drag.F)
1079      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1080        from mom_vecinv.F (similar to mom_fluxform calls).
1081    o pkg/mom_common (bottomdrag):
1082      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1083      - add options for alternative discretisation of velocity norm in quadratic
1084        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1085        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1086        improves when averaging only the other component (e.g. vVel for U bottom
1087        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1088      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1089        friction (no-slip BC) thus getting the true distance from the bottom;
1090        off by default since this also reduces model stability (explicit bottom
1091        friction). Changes produce different machine truncation with linear-drag
1092        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1093        front_relax (bvp & mxl, 10 & 11 digits).
1094    o model/src & mom pkgs:
1095      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1096        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1097      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1098        just copy level Nr value to level Nr+1.
1099    o doc:
1100      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1101    o pkg/shelfice:
1102      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1103        SHELFICE.h: move array shelficemass to init_varia, initialise
1104        from array shelficemassinit, which is set in init_fixed and
1105        has option to be set from file; introduce array
1106        shelficeMassDynTend array, set thru file in init_fixed
1107      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1108        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1109        pkg/streamice
1110      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1111        SHELFICEMassStepping = .true.
1112      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1113    
1114    checkpoint65h (2014/12/17)
1115    o verification/global_ocean.90x40x15, global_ocean_ebm:
1116      - update to generic controls.
1117    o pkg/ctrl:
1118      - ctrl_map_ini_genarr.F: test for igen>0
1119      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1120      - move gentim2d part of ctrl_map_ini_genarr.F to
1121        new separate routine : ctrl_map_ini_gentim2d.F
1122      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1123        add time variable weights and cyclic controls (time mean,
1124        seasonal cycle, etc) capabilities to gentim2d
1125    o pkg/ecco:
1126      - move reading of error, conversion to weights from
1127        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1128    o global_oce_llc90, cs32:
1129      - activte sbo.
1130      - CTRL_SIZE.h : add maxCtrlProc.
1131      - activate the new genctrl capabilities.
1132      - update following reorganization of global_oce_input_fields.tar.gz  
1133    o pkg/ctrl/ctrl_ad_diff.list:
1134      - add missing ctrl_init_rec.f
1135    o tools/OAD_support/keepOriginal:
1136      - add ctrl_init_rec.F
1137    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1138      - avoid recomputations of xx_gentim2d_dummy.
1139    o momentum diagnostics:
1140      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1141        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1142    o pkg/seaice/seaice_lsr.F:
1143      - fix computation of BU/BV, make sure they are non-zero, only necessary
1144        for cubed sphere exchanges and SEAICE_OLx/y>0.
1145        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1146    o verification/global_ocean.cs32x15/input.seaice
1147      - add test for strong implicit coupling and restricted addtive Schwarz
1148        methods for LSR
1149      - update results/output.seaice.txt
1150    o verification/tutorial_global_oce_biogeo:
1151      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1152        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1153        update output_adm,_oadm,_tlm.txt
1154    o pkg/dic:
1155      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1156      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1157        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1158    o verification/tutorial_global_oce_biogeo:
1159      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1160        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1161        update output_adm,_oadm,_tlm.txt
1162    o eesupp/src:
1163      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1164        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1165    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1166      LSR (following Hutchings et al. 2004)
1167      - introduce zetaZ as a global variable (requires adjustments in
1168        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1169        in seaice_calc_viscosities.F
1170      - new flag SEAICEuseStrImpCpl (default off)
1171      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1172        momentum equations
1173      - JFNK-solver (preconditioner) adjusted to allow using this method
1174        (where it does not have any positive effect)
1175    o pkg/seaice
1176      - add overlap for restrictive additive Schwartz method also to LSR, but
1177        turn it off by default (because it only seems to work for non-cubed
1178        sphere/llc topologies)
1179    o pkg/autodiff
1180      - add extra exchanges in addummy_in_steppging also for mnc output
1181    o pkg/seaice:
1182      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1183        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1184    o pkg/obcs:
1185      - add option to specify domain-connected piece Id along OB though files
1186        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1187      - modify obcs_diag_balance.F to process each connected-part separately;
1188        exclude OB where Id = 0 but keep the full divergence there (-> constant
1189        Psi along this portion of OB and all inflow derived from grad(Phi))
1190      - add example of OB-conect files in verification/so_box_biogeo/input.
1191    o pkg/diagnostics:
1192      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1193      a) use non zero matrix element across OB and solve for Phi 1 grid point
1194         outside OB (i.e, where tracer OBCS are applied).
1195      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1196         velocity across OB, spread it uniformly along the OB in the RHS.
1197    
1198    checkpoint65g (2014/11/19)
1199    o pkg/diagnostcis:
1200      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1201    o pkg/my82,pp81,kl10:
1202      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1203        field diffKr as background diffusivity to set minimum diffusivity value.
1204    o pkg/seaice:
1205      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1206        Bouillon et al 2013)
1207      - add SEAICE_evpAlpha/Beta to namelist
1208      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1209        involve trivial re-ordering of divisions/multiplications that should not
1210        have any effects, but ... they do change the results of lab_sea.hb87 so
1211        that only 2 digits of agreement remain, in line with the general
1212        instability/fragility of the evp-code. For now, I do not care and just
1213        update the verification experiment
1214    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1215      - remove xx_genarr2d_numsmooth etc
1216      - use xx_genarr2d_preproc etc instead
1217      - carry out smooth_correl2D at initialization stage rather than during
1218        time stepping.
1219      - get smoothOpNb from xx_gentim2d_preproc
1220    o global_oce_cs32 :
1221      - add test of generic ecco capabilities.
1222    o pkg/exf/exf_getsurfacefluxes.F :
1223      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1224    o pkg/ctrl,ecco :
1225      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1226        is defined.
1227    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1228    o model/src:
1229      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1230        diffusivity (background) is specified but ignored.
1231    o verification:
1232      - in testreport, convert hostname to lower case for default output dir name
1233    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1234    o pkg/dic: add modifications from Hajoon:
1235      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1236      - light attenuation: add self-shading effect by climatological Chlorophyll
1237        (read from file).
1238    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1239        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1240    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1241        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1242        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1243        approach where CPP_OPTIONS.h includes an omnipotent
1244        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1245    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1246        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1247    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1248        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1249        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1250    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1251      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1252      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1253      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1254      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1255    o pkg/ctrl,ecco,exf :
1256      - remove variables associated with NON-generic costs,
1257        unless ECCO_CTRL_DEPRECATED is defined.
1258      - remove NON-generic NON-obcs controls,
1259        unless ECCO_CTRL_DEPRECATED is defined.
1260    o pkg/ctrl : added ctrl_local_params.h
1261    o pkg/ecco : added ecco_local_params.h
1262    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1263        experiments, which will progressively be removed once the
1264        experiments are revised to use only generic controls/costs.
1265    
1266    checkpoint65f (2014/10/13)
1267    o pkg/ctrl, ecco, seaice : minor changes in headers
1268    o global_oce_llc90,cs32 : ecco_v4 verification exps now test generic
1269        cost function and control capabilities added since checkpoint65c.
1270    o pkg/ctrl: regroup all obcs ctrl variables in CTRL_OBCS.h.
1271    o pkg/ecco: increase modularity and improve logic
1272      - ecco_toolbox.F (new) : basic operations that are often used,
1273        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1274        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1275      - cost_gencal.F (new) : determine filnames and records.
1276      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1277      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1278        and exploit the above functions leading to more compact code.
1279      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1280      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1281        using_ers, using_gfo, using_mdt is now only defined within gencost)
1282    o pkg/ecco: extend generic cost capabilities
1283      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1284        capabilities via gencost_preproc (+ _c,_i,_r related params),
1285        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1286        gencost_outputlevel arguments to cost_generic
1287      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1288        and active_read, making room for gencost_preproc to take effect.
1289        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1290      - pkg/ecco/cost_generic.F :
1291        compute and store misfit maks*(model-data) in localdif that is
1292        then used in cost and for output, output misfit if outlev.GT.0
1293      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1294        rather gencost_barfile for deciding whether to write barfile
1295      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1296      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1297        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1298      - pkg/ecco/ecco_summary.F : report gencost variables
1299      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1300    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1301    o pkg/ecco: internal re-organization
1302      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1303        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1304        mv relevant variables definition from ecco_cost.h to ecco.h,
1305        make sure gencost routines only include ecco.h)
1306      - throughout : add missing CCP switches, rm unused variables,
1307        and rm un-necessary CPP switches
1308      - throughout gencost routines : replace modelstartdate with
1309        gencost_startdate when needed
1310      - cost_bp_read.F : use arguments, instead of common blocs
1311        so that it can be used also by (new) cost_gencost_bpv4.F
1312      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1313      - ecco_phys.F : compute etanFull
1314      - ecco_readparms.F : rename using_topex as using_tpj, add
1315        bpv4-grace to gencost list, initialize added parameters
1316      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1317    
1318    checkpoint65e (2014/09/28)
1319    o pkg/obcs:
1320      - replaced the just-added CPP options with run-time variables
1321        (see pkg/obcs/OBCS_PARAMS.h for details)
1322    o pkg/obcs:
1323      - add additional CPP options for sponge boundary layers
1324        (see pkg/obcs/OBCS_OPTIONS.h for details)
1325    o pkg/atm_phys:
1326      - implement simple (obliquity only, assuming circular planet orbit)
1327        seasonal cycle for incoming insolation ; used when run-time parameter
1328        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1329    o pkg/exf, pkg/ecco, pkg/ctrl:
1330      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1331      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1332      - implement gentim2d for xx_tauu, xx_tauv
1333    o pkg/ctrl, pkg/ecco :
1334      - fix and complement the generic controls implementation
1335    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1336        pkg/shelfice/shelfice_thermodynamics.F,
1337        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1338        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1339      - add weight in CTRL_GET_GEN calls
1340    o pkg/ctrl :
1341      - ctrl_get_gen.F : add weight as input parameter, and apply
1342        it directly rather than using smooth_correl2Dw (to be retired).
1343      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1344    o pkg/ctrl :
1345      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1346        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1347      - re-activate ctrl_summary (call in ctrl_init.F)
1348    o pkg/ctrl/ctrl_cost_gen.F :
1349      - fix CCP brackets, remove un-necessary myiter, mytime
1350    o pkg/ecco, pkg/ctrl :
1351      - remove cost_genctrl.F (now pkg/ctrl/ctrl_cost_driver.F)
1352      - remove cost_forcing_gen.F (now pkg/ctrl/ctrl_cost_gen2d.F)
1353      - add ctrl_cost_driver.F (replaces pkg/ecco/cost_genctrl.F)
1354      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1355    
1356    checkpoint65d (2014/09/15)
1357    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1358      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1359        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1360    o pkg/ctrl/ctrl_map_ini_genarr.F :
1361      - remove compilation failure
1362      - replace hard coded example
1363      - use ctrl_map_ini_gen2D, 3D
1364    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1365      - on/off switch based upon xx_genarr2d_weight,3d
1366    o src/packages_init_variables.F :
1367      - regroup pkg/estimation calls
1368      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1369        (moved to ctrl_init_variables)
1370    o cost/cost_init_varia.F :
1371      - remove ecco_cost_init_varia
1372        (moved to ecco_init_varia)
1373    o ctrl/ctrl_init_variables.F :
1374      - add CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1375      - add CTRL_MAP_INI_GENARR, SEAICE_CTRL_MAP_INI
1376    o ctrl/ctrl_map_ini.F :
1377      - remove ctrl_map_ini_genarr, seaice_ctrl_map_ini
1378        (moved to ctrl_init_variables)
1379    o ctrl/ctrl_map_ini_ecco.F :
1380      - remove ECCO_PHYS (mv to ecco_init_varia)
1381      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1382    o ecco/ecco_ad_diff.list :
1383      - add ecco_init_varia.f
1384    o ecco/ecco_init_varia.F
1385      - new routine
1386    o pkg/streamice:
1387      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1388        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1389      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1390    o pkg/generic_advdiff:
1391      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1392    o pkg/exf:
1393      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1394         xxg_precip capability
1395      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1396    o pkg/ctrl:
1397      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1398    o model/src/load_fields_driver.F :
1399      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1400        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1401    o OpenAD verification experiments:
1402      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1403        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1404        for now, only in pkgs used in OpenAD verification experiments.
1405      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1406        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1407        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1408        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1409    o OpenAD verification tests:
1410      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1411      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1412        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1413      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1414        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1415    o model/src & generic_advdiff:
1416      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1417        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1418        dynamics requires valid tracer forcing only over tile interior but, for
1419        some diagnostics, may need to extend it over 1 point in tile halo region.
1420      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1421        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1422        setting in temp/salt/ptracer_integrate.F
1423    o pkg/dic:
1424      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1425        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1426        in gchem_forcing_sep.F
1427    o pkg/autodiff & obcs:
1428      - add storage of current OB values for U & V (was already done for T & S).
1429    
1430    checkpoint65c (2014/08/30)
1431    o pkg/dic:
1432      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1433        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1434        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1435    o verification:
1436      - new experiment testing OBCS and DIC pkgs, using params & output from
1437        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1438        passage: take OBCS from the last year of a 2 yrs simulation and initial
1439        conditions from t=1.yr while keeping the same forcing.
1440    o model/src:
1441      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1442        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1443    o pkg/diagnostics (Stats-Diags):
1444      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1445        a) refine region where stats are computed, excluding where arrhFac=0 ;
1446        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1447        c) extend regional stats over the region edges (for U or V pt location).
1448    o pkg/gchem:
1449      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1450        pkg/dic is currently changing/updating ptracers values beyond the OB).
1451    o verification (hs94):
1452      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1453        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1454        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1455        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1456    o pkg/ptracers:
1457      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1458        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1459      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1460        with AB-2 code (so that it get tested).
1461    o model/src:
1462      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1463        with AB-2 code (previously only available with AB-3 code).
1464        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1465        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1466        there, by calling CYCLE_AB_TRACER).
1467    o pkg/generic_advdiff:
1468      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1469        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1470        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1471        S/R temp/salt/ptracers_integrate.F
1472    o model/src & pkg/ptracers:
1473      - remove common block variables gT,gS (in DYNVARS.h), except when
1474         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1475      - remove common block variable gPtr.
1476    o model/src & pkgs:
1477      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1478         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1479         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1480         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1481      + change accordingly all calling S/R.
1482      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1483        in S/R temp/salt/ptracers_integrate.F
1484    o pkg/seaice:
1485      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1486        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1487      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1488        in seaice_lsr
1489      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1490        in s/r seaice_lsr_calc_coeffs
1491    o pkg/mdsio:
1492      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1493        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1494        too long (e.g., > MAX_LEN_FNAM/2 )
1495    
1496    checkpoint65b (2014/08/12)
1497    o pkg/matrix:
1498      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1499    o model/src:
1500      - fix initialisation of geothermalFile; compile geothermal-flux code in
1501        natl_box verification experiment.
1502    o model/src & pkg/down_slope:
1503      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1504      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1505        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1506        results at machine truncation level: update output of experiments
1507        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1508    o pkg/diagnostics (Stats-Diags):
1509      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1510        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1511        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1512        times (but Min,Max and StD are still wrong).
1513    o model/src:
1514      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1515        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1516    o model/src:
1517      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1518        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1519        arrays are already updated while adjustments (filters, conv.adjustment) are
1520        still applied later, in S/R TRACERS_CORRECTION_STEP.
1521    o model/src:
1522      - store in common bloc array "rhoInSitu" the virtual potential temperature
1523        anomaly that is used to compute geopotential: this make the atmos code
1524        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1525    o pkg/seaice/seaice_lsr.F
1526      - rename integer variable ilcall to ipass (that's what it is called
1527        in the residual diagnostics
1528      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1529        default) for improved non-linear convergence of the first few steps
1530      - adjust a few comments and add new ones to explain some of the store
1531        directives
1532    o pkg/generic_advdiff (& ptracers):
1533      - re-work the code to check for valid advection scheme and for minimum
1534        size of overlap (now stored in local common bloc in gad_advscheme.F)
1535    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1536      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1537      - add an auxilliary variable "bet" and fix store directives and keys in
1538        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1539        less exact gradients in my tests); but there are still
1540        recomputation warning (although gradients are sort of OK), when
1541        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1542        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1543      - update verification experiments lab_sea.
1544      - change some comments in S/R seaice_calc_viscosities
1545    o model/src:
1546      - if staggerTimeStep=T, always apply exchange to velocity field in
1547        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1548        (independent of using multi-dim advection or not); no effect on FWD run
1549        but affects AD results (at machine truncation level): update output of
1550        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1551        and isomip (oad: 12.d).
1552    o pkg/generic_advdiff:
1553      - stop if doAB_onGtGs is set to FALSE but ignored
1554      - refine warning related to stability of tracer time-stepping
1555        regarding internal wave dynamics.
1556      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1557        on staggerTimeStep & implicitIntGravWave (will now get a warning
1558        if potentially unstable).
1559    o pkg/kl10:
1560      - add new pkg "kl10" for mixing due to internal wave breaking, from
1561        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1562        (contribution from Jody Klymak), tested in verification experiment
1563        verification/internal_wave/input.kl10/
1564    o isomip experiment:
1565      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1566        (input.htd) and update the output.
1567    o cd_code experiments:
1568      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1569        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1570        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1571        update the corresponding output.
1572    o pkg/seaice:
1573      - reduce the number of include files and store directives in
1574        S/R seaice_lsr_tridiagu/v
1575      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1576        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1577        get rid off one store directive (a TAF bug?)
1578      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1579        S/R seaice_lsr_tridiagv to change the loop range for consistency
1580      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1581      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1582        S/R seaice_lsr_tridiagu/v (requires update of
1583        offline_exf_seaice/input.dyn_jfnk)
1584    
1585    checkpoint65a (2014/07/27)
1586    o model/src:
1587      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1588        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1589        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1590        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1591    o model/src:
1592      - collect momentum forcing tendency into local 2-D array (passed as argument
1593        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1594        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1595        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1596      - collect T & S forcing tendency into local 2-D array (passed as argument to
1597        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1598        affects results at machine truncation level (e.g., ocean: if using
1599        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1600        correction due to vertical advection).
1601      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1602        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1603        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1604        obcs_ctrl (ad & fwd grd @ 12 & 7).
1605    o pkg/ptracers & diagnostics:
1606      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1607        title (to avoid some unexpected truncation); sort out ptracers diags units.
1608      - collect ptracer forcing tendency into local 2-D array (passed as argument
1609        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1610    
1611    checkpoint65 (2014/07/18)
1612    o pkg/fizhi:
1613      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1614        affects results at machine truncation level. Update output of experiments
1615        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1616    o pkg/seaice: more clean up
1617      - rename TAF common block tapes to be more consistent and remove
1618        unnecessary duplicates
1619      - add store directives to remove more recomputations, but use smaller
1620        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1621        The idea behind this flag is to reduce the memory footprint when the
1622        adjoint of the LSR is not required. As of now, defining the flag
1623        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1624        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1625        For experiment offline_exf_seaice, this means on a linux box with gfortran
1626        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1627        this experiment):
1628        > size mitgcmuv_ad
1629        text    data        bss     dec        hex
1630        5100659 1216  220458952  225560827  d71c8fb
1631        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1632        but only a moderate increase of 36% for global_ocean.cs32x15:
1633        text    data        bss     dec        hex
1634        6695027 1648 1014578664 1021275339 3cdf6ccb
1635        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1636      - note: there are still recomputations in global_ocean.cs32x15 and
1637        offline_exf_seaice and the gradient agreement changes (gets a
1638        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1639      - in general, the AD gradients still are wrong
1640    o OpenAD
1641      - clean up code_oad/ directories somewhat by moving files
1642        dontCompile, dontTransform, keepOriginal to OAD_support/
1643    o model/src:
1644      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1645        (not currently tested): add dissipation terms before NLFS rescaling of
1646        tendencies (previously done after).
1647    o pkg/diagnostics:
1648      - write stats-diags in ascii file with more digits (same as in monitor).
1649    o pkg/down_slope:
1650      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1651        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1652    o model/src:
1653      - new file "apply_forcing.F" containing all the code previously in
1654        external_forcing.F, but with new argument list: pass, as new argument,
1655        the current level tendency array to update (instead of a direct update
1656        of the common bloc array). Change the corresponding calls.
1657      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1658        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1659    o pkg/seaice/seaice_lsr, a little bit of clean up
1660      - rearrange some code blocks, so that now all calculations for
1661        setting up the right-hand-sides done within one single block
1662        (I find that easier to read and understand)
1663      - rearrange freedrift-code to reduce the number of ifdefs
1664      - adjust some indentations and comments
1665    
1666    checkpoint64z (2014/07/10)
1667    o model/src and several pkgs:
1668      - change argument list of all S/R called from external_forcing.F and
1669        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1670        to pass, as argument, the current level tendency array to update
1671        (instead of a direct update of the common bloc array).
1672      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1673      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1674    o pkg/seaice/seaice_lsr.F
1675      - always initialize local arrays in seaice_lsr_tridiagu/v
1676      - add more local tapes to seaice_lsr_tridiagu/v
1677      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1678        keep it in bi/bj loop; this seems to be essential
1679      - gradients are still wrong but only by 4-7 orders of magnitude
1680        instead of 15 orders of magnitude, lab_sea improves a little
1681    o pkg/seaice
1682      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1683        generates unnecessary code in seaice_lsr_ad
1684      - add more store directives in seaice_lsr to avoid unnecessary code
1685        in seaice_lsr_ad
1686      - exclude some residual computations in seaice_lsr when
1687        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1688        in seaice_lsr_ad
1689      - add more storing, a new tape (model/src/the_main_loop.F) and
1690        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1691        and klockey should be checked by a specialist)
1692      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1693        and update lab_sea after previous changes in pkg/seaice below
1694    o pkg/autodiff:
1695      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1696        viscFacInAd : run time parameters allowing for adjoint switches
1697        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1698    o pkg/ecco:
1699      - introduce cost_gencost_boxmean.F that computes a box mean
1700        temperature (for use in adjoint sensitivity studies).
1701    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1702    o pkg/mom_common/mom_calc_visc.F:
1703      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1704    o pkg/seaice/seaice_summary.F:
1705      - statement for SEAICEadjMODE now in autodiff_readparms.F
1706    o pkg/seaice:
1707      - remove some store directives and add new ones in an effort to get
1708        finally rid off the recomputation warnings. This is successful
1709        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1710        defined (i.e. no extensive recomputation warnings left), but there
1711        are still too many recomputations on the solver iteration level
1712      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1713      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1714        SEAICE_SIZE.h
1715      - add a store directive in S/R seaice_calc_viscosities
1716    o pkg/seaice (ITD code):
1717      - fix definition of Hlimit for multi-threaded case
1718      - use double precision arithmetic to compute Hlimit: this affects results;
1719        update output of experiment seaice_itd.
1720    o replace content of verification/seaice_itd
1721      - instead of a 1D column use the configuration of offline_exf_seaice
1722        to test the ice thickness distribution code with ridging
1723      - this is a first shot at this experiment
1724      - change of some defaults of ridging parameters SEAICEhStar (from
1725        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1726        and lot of new comments.
1727    
1728    checkpoint64y (2014/06/20)
1729    o pkg/seaice/seaice_reg_ridge.F:
1730      - modify the regularization of very small volumes of ice; only check
1731        total volume HEFF, and do not apply correction to individual ice
1732        classes because that leads to funny patterns in the heat and fw-fluxes
1733        into the ocean. Adjust seaice_itd/results/output.txt
1734      - replace nITD by SEAICE_multDim in loop-ranges
1735    o pkg/exf:
1736      - add code to process the case field period = -12. with UV interpolation.
1737      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1738        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1739    o verification/global_with_exf:
1740      - switch all fields period to -12. (was previously untested) in input/data.exf
1741        (but keep secondary test ".yearly" unchanged); update the reference output.
1742    o pkg/cal:
1743      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1744    o pkg/exf:
1745      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1746        to replace logical switch "exf_verbose"
1747      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1748    o pkg/sbo:
1749      - update from Katherine Quinn: evaluate mass directly from density and SSH
1750        (budget using Finite Volume method) instead of from bottom pressure.
1751      - allow testreport to collect few selected SBO output ; tested in exp.
1752        global_ocean.90x40x15 (after updating the results, to include SBO output).
1753      - fix some multi-threading issues (in output part).
1754    o model/src & most packages:
1755      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1756      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1757        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1758        "data.{pkg}" exist ; and leave the S/R (return) just after.
1759      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1760        + call LAND_READPARMS from packages_readparms.F
1761    o pkg/seaice:
1762      - remove code that resets useThSice in S/R seaice_readparms and
1763        replace it by a warning in S/R seaice_check
1764      - remove parameter MULTDIM, replace with nITD and runtime
1765        parameter SEAICE_multDim (still hard-wired to nITD if
1766        SEAICE_ITD is defined)
1767    
1768    checkpoint64x (2014/05/24)
1769    o verification/lab_sea:
1770      - update adjoint and TLM output following changes to pkg/salt_plume
1771      - un-do the update after putting back local recip_Cp in few places.
1772    o pkg/salt_plume: modifications by An Nguyen:
1773      - add capability to do brine rejection (salt-plume) as function of
1774        volume+tracers (instead of only salinity tracer).
1775      - conserve volume by exchanging volume from each kLev to above to
1776        accommodate in-coming brine volume
1777      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1778      - switch KPP surf buoyancy due to brine forcing to 3-d
1779        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1780      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1781      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1782        in East/West Arctic.
1783    o pkg/sbo:
1784      - incorporate modifications from Katherine Quinn to enable the use of sbo
1785        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1786        output for future testreport verification (unfinished).
1787    o pkg/atm_phys:
1788      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1789        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1790        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1791    o pkg/seaice
1792      seaice_calc_ice_strength.F: modify expression to avoid divisions
1793        (affects truncation)
1794      seaice_do_ridging.F: clean up the insectarium
1795      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1796      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1797      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1798      - add some debugging information and error messages (warnings)
1799    o model/src: modifications relatd to atmosphere p*:
1800      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1801      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1802        of vertical profile tRef in geopotential background and anomaly.
1803      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1804        and pkg/atm_phys.
1805      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1806        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1807    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1808    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1809        not used right now, but can be used in BGC packages to fix conservation.
1810    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1811        other packages too.
1812    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1813        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1814    o model/src:
1815      - since we have several heat capacity (even in model/src), define "recip_Cp"
1816        as local variable (no longer in common block) to avoid any confusion.
1817      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1818    o pkg/exf:
1819      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1820        air density as function of air Temp, Humidity and atm pressure.
1821    
1822    checkpoint64w (2014/05/02)
1823    o verification:
1824      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1825        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1826        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1827        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1828        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1829    o model/src: for atmosphere in p* coords:
1830      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1831      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1832        but not yet activated.
1833    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1834      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1835      - this changes the results (but not for any verification experiment, because
1836        none tests this), but avoids having an extra field in the restart files
1837    o pkg/seaice: remove global variable TICE (not needed)
1838      - replace by TICES or local variable where necessary (cost_seaice_test,
1839        seaice_diagnostics_state)
1840      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1841      - use specific read/write routines for reading and writing individual leves
1842        of a multilevel field
1843    o pkg/ctrl & model/inc:
1844      - move additional anomaly fields of control vars (related to options:
1845         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1846        from DYNVARS.h into new header file: CTRL_FIELDS.h
1847    o pkg/seaice: some small modifications to the ridging code
1848      - make fw2ObyRidge a global variable and add the freshwater flux to
1849        seaice_growth
1850      - pass actual thickness from seaice_prepare_ridging, so that it is
1851        computed only in one place and compute it in the same way as in
1852        seaice_growth
1853      - initialise more fields in seaice_do_ridging that where cause floating
1854        point exceptions over land
1855    o pkg/seaice: preparations for ridging code and first real ridging code
1856      - move most of "PART 1" of S/R seaice_growth into a new and separate
1857        S/R seaice_reg_ridge that will both regularize the state variable after
1858        advection call the actual ridging routine;
1859      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1860        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1861      - remove ridging code from seaice_advdiff
1862      - clean up remaining part 1 of seaice_growth in an attempt to make it
1863        more readable (this is probably subjective)
1864      - call seaice_itd_redist once in the initialisation phase to have the initial
1865        conditions in the correct category
1866      - finally: add new ridging routine for ITD code
1867    
1868    checkpoint64v (2014/04/11)
1869    o pkg/ecco:
1870      - add runtime parameters mdt[start,end]date[1,2]
1871      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1872    o pkg/seaice:
1873      - make deltaC a global variable, so that it can be used in ridging code
1874      - first step towards ridging: introduce new routines that compute
1875        ice strength based on ridging parameters
1876      - add diagnostic for HSNOWITD
1877      - add opnWtrFrac as a global variable (required for ridging scheme)
1878    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1879      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1880        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1881    o verification/hs94.1x64x5:
1882      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1883      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1884    o autodiff:
1885      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1886        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1887        For now, only in pkgs used in verification/hs94.1x64x5.
1888      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1889        which are specific to TAF/TAMC).
1890      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1891        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1892        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1893      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1894        building mitgcmuv_ad (make adAll).
1895    o pkg/ecco:
1896      - cost_gencost_seaicev4.F:
1897         reformulate proxy cost as function of sst and local param SEAICE_freeze
1898         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1899      - add stop statement if old names siv4-[sst,vol] are used
1900      - add snapshots + cost reports for atmospheric longwave
1901      - remove factor 0.1 in front of wtau[u,v]
1902      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1903         ALLOW_TMI_SST_COST_CONTRIBUTION
1904    o pkg/atm_phys:
1905      - add some diagnostics for Short-wave and for convection S/R.
1906    o pkg/seaice/seaice_growth:
1907      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1908        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1909      - rearrange loop order for better vector code in the same code block
1910      - rewrite the floeDiameter formula to have fewer divisions
1911      -  (miraculously) none of this changes the results of seaice_itd
1912    o pkg/smooth:
1913      - move param smooth2Ddiffnbt to pkg/ecco
1914    o pkg/salt_plume:
1915      - salt_plume_frac.F:
1916         clean up local param names
1917         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1918    o pkg/rw:
1919      - add RS version of S/R READ_MFLDS_LEV.
1920    o pkg/streamice:
1921      - fix the restart test by writing/reading pickup_streamice files.
1922    o pkg/seaice:
1923      - refine checks for jfnk-related parameters
1924      - comment out if statement with SEAICEuseIMEX parameter as long as there
1925        is no IMEX code to avoid confusion and surprises
1926    
1927    checkpoint64u (2014/03/07)
1928    o verification/MLAdjust:
1929      - rename secondary test suffix:
1930         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1931         0.leithD -> AhFlxF  + switch to flux-form
1932         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1933         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1934    o pkg/mom_vecinv:
1935      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1936        to be before mom_calc_visc.F)
1937      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1938      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1939        this is simpler for the adjoint and for diagnostics.
1940    o model/src + pkg/momentum:
1941      - add input files for  2-D additional Western and Southern cell-edge wall
1942         (e.g., to add "thin-wall" where it is =1).
1943      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1944        using 2nd hFacZ that is computed from initial (fix domain) hFac
1945      - known limitations of thin wall implementation: not yet coded for sigma
1946        coords; not working with CD-scheme neither.
1947    o pkg/seaice:
1948      - rename recently introduced parameters from (wrong name) AB to
1949        BDF (backward difference time discretisation)
1950      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1951    o tools/adjoint_options:
1952      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1953    
1954    checkpoint64t (2014/02/01)
1955    o pkg/ecco
1956      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1957        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1958      - replace hard-coded record number and period which only work for monthly
1959        with read-in runtime param that works for other periods (month,day,year)
1960    o pkg/thsice
1961      - corrected store directive fixes thsice adjoint gradient checks
1962    o genmake2 & testreport:
1963      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1964        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1965        Update testreport accordingly. No need to set "export OPENAD=true"
1966        in adjoint_options/adjoint_oad anymore (will be removed later).
1967    o pkg/shelfice:
1968      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1969        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1970        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1971    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1972      - Changes to make GENARR more modular (i.e. invisible if not used)
1973    o model/src/temp_integrate.F and salt_integrate.F
1974      - re-include store directives that were removed on Dec 27th.
1975    o model/src/external_forcing_surf.F
1976      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1977        seaice_model in the adjoint that is problematic when seaice_model is
1978        turned off in the adjoint. The resolved issue dated back to July when
1979        EXTERNAL_FORCING_SURF call was moved.
1980        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1981    o pkg/exf/exf_check.F
1982      - fix a small bug again (originally found by Wentao Liu, now found again)
1983      - streamline error output
1984    o pkg/streamice and aim_v23:
1985      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1986        Apple's /usr/bin/cpp knows what to do:
1987        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1988        Target: x86_64-apple-darwin13.0.0
1989    
1990    checkpoint64s (2014/01/05)
1991    o tools/adjoint_options:
1992      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1993        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1994    o model/src:
1995      - remove some unnecessary TAF storage directives in forward_step.F and
1996        in dynamics.F (note: not always removed by TAF, e.g., double storage
1997        of kappaRU,kappaRV in former version of dynamics.F).
1998    o model/src & pkg/ptracers:
1999      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
2000        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
2001        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
2002      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
2003      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
2004      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
2005    o useSingleCpuInput separates single-CPU input from single-CPU output;
2006        for now only implemented for in exf_interp_read.F
2007    o verification/advect_xy:
2008      - fix missing EXCH call in local version of ini_salt.F and update output.
2009    o momentum diagnostics:
2010      - fix which deltaT is used in Total-Tendency diagnostics.
2011      - fix typo in diagnostics for momentum tendency from AB.
2012    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
2013        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
2014    
2015    checkpoint64r (2013/12/08)
2016    o verification/*/results:
2017      - Update reference output of experiments that were passing with just 13 digits
2018         (make it easier to detect future changes in results)
2019    o model/src & pkg/ptracers:
2020      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
2021        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
2022        to inside ptracers_integrate.F ; remove ptracers_advection.F
2023    o coupling interface pkgs:
2024        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
2025      - change the config check to test the agreement of Ocean Depth
2026        with ATM land/sea mask (instead of ATM orography);
2027      - send to coupler the number of coupler time-steps to do for this run:
2028        this allows to check for consistency and don't need anymore to be
2029        specified in parameter file "data";
2030      in coupler:
2031      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
2032      - improve report to log-file of config setting (pass log-file unit to few S/R)
2033    o pkg/compon_communic:
2034      - add coupling send/receive for non-tiled integer vector;
2035      - add S/R to check and stop if any proc has an error (similar to
2036        eesupp/src/stop_if_error.F but single thread and across Comm_World).
2037    o pkg/exch2:
2038      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
2039        through list of all tiles my proc owns.
2040    o model/src:
2041      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
2042        from rTrans) to simplify dependencies (no need to store rTrans anymore in
2043        calling S/R); this affects AD results at machine truncation level:
2044        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
2045        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
2046    o tools/build_options:
2047      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
2048    o coupling interface pkgs:
2049        [compon_communic, atm_compon_interf & ocn_compon_interf]
2050      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
2051        to each S/R that needs it; remove un-used variables.
2052      - change component tile registration (cpl_register.F in both compon_interf
2053        and mitcomponent_tile_register.F) to pass the full list of tiles
2054        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
2055      - with pkg/exch2: adopt the same convention used for I/O to define mapping
2056        towards coupler global array (unless W2_useE2ioLayOut=F):
2057         a) can now use different tiling between atm & ocn comp.
2058         b) no needs to modify the run-Off map when changing tiling (was needed
2059            even if using the same tiling between atm & ocn).
2060         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
2061            full land tiles); not yet tested.
2062      - check for valid mapping from comp. tile to coupler global array
2063      - improve report of tile registration results to log file.
2064    o pkg/exch2:
2065      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
2066        tile-registration (CPL_REGISTER);
2067      - activate (un-comment) definition and setting of "W2_tileIndex" list to
2068        store the local bi,bj indices of each tile;
2069      - also print bi,bj in local report to log file;
2070      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
2071        Jun 2009 modif of pkg/exch2).
2072    o testing on baudelaire:
2073      - run 2 tests at a time: no significant slow down (since enough cpu) and
2074        get the full set of test done earlier
2075      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
2076    o model/src/thermodynamics.F and routines called from it:
2077      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
2078        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
2079        velocity (outp) by adding bolus velocity.
2080      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
2081        mass transport from velocity + lateral grid cell area
2082      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
2083      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
2084     in thermodynamics.F
2085      - remove k from thermodynamics.F and move it to temp_integrate.F
2086        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
2087        loop).
2088      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
2089        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
2090        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
2091        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
2092      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
2093        global_ocean.90x40x15, tutorial_global_oce_biogeo and
2094        tutorial_tracer_adjsens (+ TLM output).
2095    o tools/OAD_support and (verification/*/) code_oad:
2096      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
2097        module conversion ; remove unneeded CPP_EEOPTIONS.h.
2098      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
2099        version (closer to model/inc/CPP_OPTIONS.h).
2100    o model/src:
2101      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
2102        retired list of parameters (routine FREEZE has been replace by surface
2103        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
2104    o pkg/gmredi:
2105      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
2106        velocity (same scheme but affects machine truncation) for GM_AdvForm.
2107      - update output of FWD experiments: front_relax.bvp,
2108        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
2109    
2110    checkpoint64q (2013/11/17)
2111    o verification:
2112      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
2113        tutorial_global_oce_biogeo and global_ocean.90x40x15.
2114      - generate new output (growth & melt) for seaice_itd experiment after
2115        updating the input pickup_seaice files (previously wrong).
2116    o pkg/cost:
2117      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
2118        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
2119        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
2120          cannot be applied to var in common block).
2121        o allows to get results independent of tile-per-proc setting (if using
2122          slower GLOBAL_SUM_SEND_RECV option).
2123      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
2124        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
2125        forward gradients: update output).
2126      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
2127        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
2128    o pkg/mom_common:
2129      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
2130        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
2131        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
2132        ensure that all field value that are used are set.
2133    o tutorial_deep_convection (smag3d):
2134      - add missing scaling in mom_calc_smag_3d.F;
2135      - set smag3D_coeff in input.smag3d such that results do not change.
2136    o pkg/dic:
2137      - change dic_cost.F to compute cost on each tile first and then apply
2138        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
2139        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
2140      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
2141    o eesupp/src & pkg/mdsio:
2142      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
2143        (from pkg/mdsio) since they are no longer used for tape IO.
2144      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
2145        (+ keep a copy in pkg/atm_ocn_coupler).
2146    o verification/isomip:
2147      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
2148    o tools/build_options:
2149      - optfile linux_amd64_ifort11, fast (no ieee) case:
2150        to get a working restart for all experiments, add "-fp-model source"
2151        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
2152    
2153    checkpoint64p (2013/10/20)
2154    o pkg/autodiff:
2155      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
2156        criteria, return to simple (default) tape IO format.
2157    o pkg/mdsio (+ eesupp/src):
2158      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
2159        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
2160      - fix globalFile and singleCpuIO options using simpler global mapping.
2161      - new pairs of scatter/gather vector S/R (one for each type, generated from
2162        template) corresponding to simpler global mapping.
2163      - adread_write.F: switch to new S/R (but leave old calls commented) and write
2164        to globalFile when parameter globalFiles is set to True.
2165      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
2166    o pkg/autodiff:
2167      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
2168        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
2169        missing, just add a STOP if array type do not match.
2170    o pkg/exf:
2171      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
2172         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
2173         and rename array obsSIce to exf_iceFraction.
2174    o tutorial_deep_convection:
2175      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
2176        for now all in this exp. code dir.
2177      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
2178        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
2179    o eesupp/src:
2180      - added SINGLE_DISK_IO option because reading of parameter files on
2181        very large number of processors did not work with existing set-up
2182    
2183    checkpoint64o (2013/09/25)
2184    o pkg/atm_phys & atm_compon_interf:
2185      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
2186    o tools/build_options:
2187      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
2188        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
2189        remove CPP setting (was identical to genmake2 default).
2190    o pkg/gmredi & model/src: Some updating and work done on the residual model.
2191      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
2192      - fixed up the calculation of the eddy stress and how it is added to the
2193        external forcing via taueddy_external_forcing.F
2194      - at the moment, it is very experimental and only works with the variable eddy
2195        diffusivity calculated in gmredi_k3d.F
2196    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
2197        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
2198    o testreport (& tools/do_tst_2+2):
2199      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
2200    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
2201      - remove CPP='cpp -traditional -P' (this is genmake2 default)
2202      - add switch (for big setups) to use 'medium' memory-model (but leave it
2203        commented out for now). Note: needed with FC 19 to compile big setups.
2204    o pkg/atm_compon_interf:
2205      - regroup per field origin (model & pkgs) the coupling storage routines
2206         (which accumalate in time each coupling field)
2207      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
2208        update accordingly + simplify aim_do_physics.F
2209    
2210    checkpoint64n (2013/08/26)
2211    o pkg/bbl:
2212      - update formulation to reduce dispersion of tracer properties in bbl
2213      - replaced horizontal and vertical transport parameters with velocities
2214      - changes results for verification/global_with_exf.yearly
2215    o verification/halfpipe_streamice:
2216      - change to matrix construction; update both Fwd & AD output.
2217    o verification/tutorial_tracer_adjsens:
2218      - OpenAD test: switch to vector-invariant momentum since fluxform with
2219        rStar causes problems with OpenAD; update output.
2220    o tools:
2221      - genmake2: define a common prefix for all temp-file names ; move them
2222        to local /tmp disk (but would be easy to move them back);
2223      - xmakedepend: apply the same switch for temp-files.
2224    o pkg/offline:
2225      - changes for use with rStar (NLFS): assume that we continue to provide
2226        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
2227        output files) and apply r* scaling at each time-step (function of the time
2228        varying Eta field); use normal pickup files (needed for restart with NLFS).
2229    o adjoint with OpenAD:
2230      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
2231        package openad.  This package has to be compiled for all runs with OpenAD
2232        instead of specifying code_oad_all as a modification directory.
2233      - link the fortran templates from tools/OAD_support to the build directory
2234        for preprocessing to avoid conflicts between different setups compiled
2235        simultaneously and simplify cleanup.
2236    o pkg/exf:
2237      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
2238        main model or other pkgs are exchanged in EXF_MAPFIELDS).
2239    o model/src:
2240      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
2241        (similar to do_fields_blocking_exchanges.F).
2242    o tools/genmake2:
2243      - remove TAF output src code just before calling staf (when not doing a fresh
2244        built, will stop if things go wrong with staf).
2245      - fix target "adobj" (left from TAF version-2 transition)
2246    o pkg/diagnostics:
2247      - add a parameter to track the status of pkg/diagnostics activation;
2248        this replace/extend the use of logical param "settingDiags" (to check
2249        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
2250        New S/R to print error message and stop when pkgStatus is not right.
2251      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
2252    
2253    checkpoint64m (2013/08/13)
2254    o model/inc:
2255      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
2256        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
2257    o pkg/kpp & aim_v23:
2258      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2259    o pkg/seaice:
2260      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
2261        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
2262      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2263    o eesupp/src:
2264      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
2265        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
2266    o switch to TAF version-2:
2267      - add flow directives to "freeze" naming convention for ad-routines that
2268        are used in I/O routines of adjoint state and associated common blocks
2269        that are used in adcommon.h (backward compatible with version-1)
2270      - update all ad-optfiles (in tools/adjoint_options + few local to some
2271        verification exp) to switch to latest TAF version (currently 2.5.5);
2272        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
2273        out except for diva).
2274      - the major change with TAF version-2 is that both the differentiated
2275        routines and the forward routines (new) are returned as part of the TAF
2276        output source code. Update genmake2 accordingly.
2277      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
2278        with version-2 when compared to TLM or FWD gradient); other experiments
2279        output show minor changes (machine truncation level); update the few AD &
2280        TLM output with 12 matching digits only (some prior to version-2 switch).
2281    
2282    checkpoint64l (2013/08/05)
2283    o model/src:
2284      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
2285      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
2286        when using TAF but only if using OpenAD.
2287    o pkg/mom_common+fluxform+vecinv:
2288      - always set horiz. viscosity arrays to background value before calling
2289        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
2290        only when using variable horiz. viscosity (useVariableVisc=T);
2291      - simplify mom_vecinv.F (only 1 block for momViscosity).
2292    o pkg/mom_common: variable horiz. viscosity in NH code
2293      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
2294        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
2295      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
2296        useBiharmonicVisc & useVariableVisc.
2297      - fix old bug (already in 1rst implementation of variable horizontal viscosity
2298        in calc_gw.F, version 1.27, 2006/06/20):
2299        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
2300        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
2301      - change background horiz viscosity in vertical momentum (gW) to always be
2302        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
2303        any type of variable viscosity, e.g., viscAh/4Grid)
2304      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
2305        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
2306        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
2307        default viscAh,viscA4 is zero).
2308    o model/src:
2309      - extend length of drC & recip_drC from Nr to Nr+1.
2310  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
2311    - genmake2: do not create local ./mpi_headers dir when no file to copy into.    - genmake2: do not create local ./mpi_headers dir when no file to copy into.
