5      ==============================      ==============================
6    
7    checkpoint66j (2017/08/15)
8    o pkg/ptracers:
9      - fix surface forcing under ice-shelf (useShelfIce=T).
10    o pkg/atm_phys:
11      - use hFac weighted average when applying A-grid atm-phys momentum tendency
12        to C-grid dynamics; this ensures wind-stress match mom tendency.
13    o eesupp/src:
14      - change default for opening scratch files to avoid STATUS='SCRATCH'
15      - close scratch files with STATUS='DELETE'
16      - changes affect eeset_parms.F and open_copy_data_file.F and many routines
17        that read namelists (because they close the scratch files)
18      - you can revert to old default by setting USE_FORTRAN_SCRATCH_FILES
19        in CPP_EEOPTIONS.h (tested in ideal_2D_oce/code & lab_sea/code_ad)
20    o pkg/atm_phys:
21      - fix unset arguments in (unused) S/R surface_flux_0d.
22    o eesupp/src:
23      - add argument "procId" to S/R EESET_PARMS to fix  scratchFile1 & 2 setting
24        (case TARGET_BGL or TARGET_CRAYXT) for early call (from eeboot_minimal.F):
25        called with myProcId in eeboot.F and with mpiMyWId in eeboot_minimal.F
26    o pkg/streamice:
27      - remove blank between _EXCH_XY_RL and "()", which my Apple Xcode
28        preprocessor /usr/bin/cpp cannot interpret; 3 instances in total in
29        streamice_driving_stress_fd.F and streamice_advect_2dtracer.F
30    o pkg/diagnostics:
31      - new option to allow to cumulate thickness-factor (hFac) weighted field
32        (if field permitted); implemented by changing sign of "jdiag" pointer
33        (> 0: cumlulate field, < 0: cumulate hFac weighted field).
34        a) restricted to 3-d (Nr levels), level centered diagnostics at U,V or Cell
35           center position (gcode(2)='U','V','M' & gcode(3,5,9:10)='R',' ','MR')
36        b) for now, activated by setting fileFlags 3rd character to 'h'.
37    
38    checkpoint66i (2017/07/18)
39    o pkg/cheapaml:
40      - add parameter "useRelativeWind", default set to False; this change the
41        previous setting which was always using relative wind.
42    o add hooks for the Parallel Data Assimilation Framework PDAF
43        (http://pdaf.awi.de/) in eeboot_minimal.F and the_main_loop.F;
44        to use set CPP-flag USE_PDAF in CPP_EEOPTIONS.h
45    o pkg/exf:
46      - interpolation of vector fields (exf_interp_uv.F): fix bug in calculation
47        of South-Pole mean value.  
48      - interpolation near the poles, case where second additional row is at the
49        pole (or beyond the pole and moved to the pole): change first addition row
50        value to a linear interpolation between pole and 1rst (S.pole)/last (N.pole)
51        row (instead of just a copy of it).
52    o pkg/seaice:
53      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
54      - add the option to compute no-slip du/dy, dv/dx (i.e.
55        the offdiagonal strain rate e12) by a second order approximation
56        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
57        it is too messy to implement for the implicit LSR matrix.
58        SEAICE_2ndOrderBC = .FALSE. by default
59    
60    checkpoint66h (2017/06/02)
61    o pkg/seaice:
62      - add new routines to compute stress tensor components and stress tensor
63        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
64      - change names of diagnostics SIsigI/II (commonly used for invariants)
65        to SIsig1/sig2 (more common for principal components) to avoid confusion
66    o pkf/exf:
67      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
68        similarly, stop if rotateStressOnAgrid with constant wind-stress.
69    o pkg/seaice:
70      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
71        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
72      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
73        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
74    o pkg/diagnostics:
75      - small piece of code to rename (old) diagnostics, when namelist is processed.
76    o model/src:
77      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
78        originally, set as minimum of adjacent hFacC factor ; now (new default)
79        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
80        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
81    o pkg/seaice:
82      - add momemtum advection, off by default, still in test phase
83        most of the momentum advection code is adapted and reused from mom_vecinv
84    o pkg/mom_vecinv:
85      - pass these runtime flags:
86        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
87        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
88        so that these routines can also be used in pkg/seaice.
89    
90    checkpoint66g (2017/04/24)
91    o model/src:
92      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
93        to get same expression (regarding machine truncation) in different places
94        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
95        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
96        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
97    o pkg/shelfice:
98      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
99        to shelfice_init_fixed.F
100      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
101        ini_masks_etc.F for now) to update ocean upper boundary position according
102        to ice-shelf topography (instead of directly updating hFacC).
103    o model/src:
104      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
105        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
106    
107    checkpoint66f (2017/04/06)
108    o model/src:
109      - add specific run-time param to select level of printed plot-field-maps,
110        set by default to debugLevel. Remove internal param "printDomain".
111    o pkg/seaice:
112      - add flag to add snow mass to seaiceMassC/U/V, the default is
113        SEAICEaddSnowMass=.FALSE., not to change previous results
114    o pkg/bling
115      - Bug fix in bling_production regarding unit conversion for diagnostics
116        being put in the wrong place
117    o model/src:
118      - add back recomputation of rSurfW & S to ensure consistent column thickness
119        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
120        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
121        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
122    o pkg/autodiff:
123      - clean-up "checkpoint.flow"
124    o pkg/rw (Contribution from Jody Klymak):
125        option to set mds file suffix as function of time in simulation:
126        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
127           to select file suffix format; by default (=0), use iteration number;
128        *) add simple routine to return file suffix according to rwSuffixType;
129        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
130           use new S/R to get file suffix, except for debug output file (diagFreq)
131           and pkgs offline & rbcs input files.
132    o pkg/rw:
133      - uniform processing of "I10" suffix across writing fld routines; used to
134        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
135        (similar to cg3d.F, cg3d_ex0.F)
136    o pkg/mom_vecinv:
137      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
138        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
139    o pkg/bling:
140      - Many small changes intended to clean the code.
141        Unnecessary ADJOINT_SAFEs removed ;
142        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
143        diagnostics added.
144    
145    checkpoint66e (2017/03/14)
146    o pkg/exf:
147      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
148        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
149        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
150        avoid any dynamic allocation ;
151      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
152        read-in ; add warning when file is read-in but not used within pkg/exf ;
153        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
154      - update exf_summary.F (print {FLD}RepCycle).
155    o verification/global_with_exf:
156      - switch on exf interpolation in AD test (just like the forward test)
157    o pkg/mom_vecinv:
158      - add storage directives to avoid recomputations within mom_vecinv.F
159        which were generating seg. fault with gfortran -devel
160    o pkg/ctrl, pkg/smooth:
161      - initialize array halos which were generating seg. fault with
162        gfortran -devel in adjoint mode
163    o pkg/exf:
164      - for each input field, enable to specify a field specific repeat-cycle
165        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
166    o verification/lab_sea:
167      - update AD results of primary test and noseaicedyn test after switching
168        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
169        check stays about the same.
170    o pkg/exf:
171      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
172      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
173    o pkg/bling, USE_EXFCO2 code:
174      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
175      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
176    o pkg/exf:
177      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
178      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
179        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
180        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
181      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
182        EXF_INIT_FLD) and update calls in exf_init_varia.F
183      - For now, for backward compatibility, keep a simplified version of S/Rs
184        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
185      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
186        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
187    o tools/genmake2:
188      - replace "bc -l" (only used once) by "expr" (already used).
189    o verification/global_ocean.cs32x15:
190      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
191        Note: exf setting (data.exf) can be compared to other exf secondary exp
192        "seaice" (kept with useCAL=T) which has same time dependent forcing.
193    
194    checkpoint66d (2017/02/13)
195    o pkg/exf:
196      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
197        early on (in packages_boot.F) to stress this change in pkg setting.
198      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
199    o model/src:
200      - move call to ecco_phys to end of time step; this may induce minor
201        cost function changes by shifting time averages by one time step
202        for some variables; this revision resulted in changed adjoint results
203        in MITgcm_contrib/verification_other/global_oce_cs32
204    o pkg/exf:
205      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
206        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
207        e.g. precip, are not available.
208    o pkg/flt:
209      - flt_init_varia.F: use pickupSuff if specified
210      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
211        intermediate, step towards completing pkg/exch2 support within pkg/flt;
212        ifdef DEVEL_FLT_EXCH2 then:
213        - flt_init_fixed.F: comment out stop
214        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
215        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
216        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
217        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
218    o tools/genmake2 & pkg/pkg_depend:
219      - define new type of pkg dependency rule ("=pkg_x"), less strict than
220        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
221        (-pkg_x in packages.conf).
222      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
223      - add "+cal" to dependency list of pkg/ecco (needed to compile).
224      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
225    o utils/matlab:
226      - adding ocean_basin routines for defining basin masks.
227    o pkg/exf:
228      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
229        arguments, allowing to check (and stop) if parameter setting of
230         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
231        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
232        for backward compatibility.
233      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
234        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
235    o pkg/bling (USE_EXFCO2 code):
236      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
237        by adding a call to S/R EXF_GETFFIELD_START.
238    o pkg/exf:
239      - allows to compile without pkg/cal (but disabled by current dependency
240        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
241        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
242        of {FLD}startdate1 & date2 ; consistency check not yet coded.
243    o verification/global_ocean.cs32x15:
244      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
245        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
246    o pkg/exf:
247      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
248        calculations); change FWD experiment global_ocean.cs32x15
249        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
250    o pkg/exf:
251      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
252         {FIELD}startdate to {FIELD}StartTime
253        Note: new name also fit better the content, i.e, a start time in second.
254    o eesupp/src:
255      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
256    o pkg/exf:
257      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
258        to allow to read-in Sensible & Latent Heat flux ;
259      - simplify pkg/exf main options:
260        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
261           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
262           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
263        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
264           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
265        3) improve options documentation in EXF_OPTIONS.h.
266    o pkg/ecco:
267      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
268        ecco_summary.F: add passive tracer cost functions to gencost;
269        m_ptracer and m_boxmean_ptracer
270    o pkg/ctrl:
271      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
272        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
273        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
274        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
275    o model/src:
276      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
277        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
278    o pkg/exf:
279      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
280        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
281    
282    checkpoint66c (2017/01/19)
283    o verification:
284      - add new option "-src" to testreport to only produce source code (*.f),
285        including taf output src code (if using '-adm'/'-tlm' option).
286    o pkg/exf:
287      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
288    o pkg/diagnostics:
289      - add run-time variable diagMdsDir to specify a subdirectory for
290        diagnostic output when mds is being used and mdsioLocalDir is not.
291    o pkg/mnc:
292      - mnc_utils.F: edit stop message
293    o pkg/autodiff:
294      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
295        add HAVE_SYSTEM bracket around system call to mkdir
296    o pkg/profiles:
297      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
298        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
299      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
300        add HAVE_SYSTEM bracket around system call to mkdir
301    o pkg/smooth:
302      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
303      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
304      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
305    o pkg/exf:
306      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
307        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
308        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
309      - summary: skip detailed field report if not used (empty file-name).
310    o tools/xmakedepend:
311      - In case line editor "ed" is missing, switch to "sed" command to clean-up
312        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
313    o pkg/exf:
314      - change definition of "hflux" input file to always include Short-Wave;
315        this is now consistent with hflux computation (if using bulk-formulae)
316        and hflux diagnostic & documentation (in EXF_FIELDS.h).
317    
318    checkpoint66b (2016/12/01)
319    o model & momentum pkgs:
320      - implement fully implicit bottom friction combined with implicit surf.
321        pressure, for now, only in hydrostic formulation:
322        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
323          and run with selectImplicitDrag=2 ;
324        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
325      - partial implicit time-stepping (bot. friction + vert. visc first, then
326        surf. press) corresponding to selectImplicitDrag=1 should be applicable
327        to NH formulation but not available until we solve for surf. pressure
328        increment (instead of full etaN).
329      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
330        with implicit vertical viscosity.
331    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
332      - this is a first version that includes many regularisations that may
333        not all be necessary, to be sorted out,
334      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
335      - change one verification experiment in seaice_itd to use and test new code
336      - seaice_growth: catch a case where the argument of log can be zero
337        or smaller (important for code stability)
338    o model/src:
339      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
340        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
341        similar A.X'=Y' system (with same matrix A) in subsequent calls;
342        switch based on errCode (In/Out) argument value; in calling routines,
343        initialise errCode before first call.
344    
345    checkpoint66a (2016/10/18)
346    o pkg/bling:
347      - BLING package now loads in atmospheric pCO2 file using exf package routines
348        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
349    o model/src & pkg/ptracers:
350      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
351        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
352        implicitDiffusion (respectively) are used (even without momImplVertAdv
353        or temp,salt,PTRACERS_ImplVertAdv).
354    o model/src & generic_advdiff:
355      - add parenthesis in main diagonal calculation of implicit vertical
356        diffusion matrix (impldiff.F & gad_implicit_r.F).
357        This affects results at machine truncation level; update output of many
358        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
359    o pkg/mom_commom & generic_advdiff:
360      - add deep atmosphere and anelastic scaling factor in implicit vertical
361        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
362    o model/src:
363      - remove few unnecessary temp array copies in solve_tridiagonal.F
364        & solve_pentadiagonal.F
365    
366    checkpoint65z (2016/09/28)
367    o pkg/seaice: fix multithreading for seaice_fgmres.F
368      - remove unecessary variables from common blocks
369      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
370        basis, that are stored in commom blocks (including integer variable i1)
371      - clean up code a little by removing commented lines that refer to
372        original code
373      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
374    o MITgcm manual:
375      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
376        preliminary documentation for generic controls (8.3; ctrl.tex),
377        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
378        ecco_costfunction.tex
379    o pkg/ecco:
380      - update and cleanup list of CCP options
381      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
382        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
383      - add checks that retired run-time options are not used, and in relation
384        to gencost_mask and gencost_errfile
385      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
386        gencost_nrecperiod
387      - fix m_eta computation for virtual salt flux case
388      - add m_horflux_vol case (selected via gencost_barfile) that computes
389        transports via cost_gencost_boxmean (gencost_flag=-3)
390      - use gencost_flag more systematically (i.e., avoid using gencost_name)
391        for code switches (aside from physical variable selection)
392    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
393      attempt appears to be a bit of a hack and my need some repair down the road
394    o pkg/exf:
395      - interpolation near South Pole: fix criteria on input field latitude.
396    o pkg/icefront & pkg/exf:
397      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
398        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
399    o pkg/exf:
400      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
401        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
402        (add suffix "_out" instead of a prefix); keep same record number as in
403        input file but always write record 1 first (to avoid a STOP in I/O S/R).
404        Change output file content by writing interpolated field before applying
405        land-sea mask (helpful for debug).
406      - 2 compon. vector interpolation with rotation: apply scaling factor on
407        each compon. (Eastward and Northward) just before rotation.
408    o pkg/bling:
409      - Cleaned package. Removed not needed code and comments.
410      - adjoint example now works
411        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
412    o pkg/ptracers:
413      - add Bruno Deremble's code to complete the linear surface correction
414        for tracer conservation;
415      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
416    
417    checkpoint65y (2016/07/29)
418    o pkg/debug (stats):
419      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
420        proc/thread mapping);
421      - fix Min & Max for case where 1 thread has only empty tiles;
422      - use RL variable to count number of wet grid points (with big domain,
423        can be too large to fit into integer*4).
424    o pkg/monitor:
425      - use RL variable to count number of wet grid points (but used only for del2)
426      - add new routine to compute Advective CFL within tracer time-stepping with
427        writing delayed until next monitor output.
428    o pkg/obcs:
429      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
430    o pkg/cal:
431      - calandar-dump: treat case myTime < timePhase in the same way as in
432        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
433    o pkg/dic & seaice:
434      - fix compilation of ocean component for coupled atm+ocn model with
435        seaice dynamics & dic.
436    
437    checkpoint65x (2016/06/11)
438    o add a license text file in main MITgcm tree.
439    o added pkg/bling:
440      - intermediate complexity biogeochemical model
441      - see bling_description.txt for details
442      - verification experiment is global_oce_biogeo_bling (for now, in
443        Contrib/verification_other/); tested daily on baudelaire with gfortran.
444      - add entry point in pkg/gchem for new pkg "bling".
445    o pkg/seaice: fix tensile stength computation
446      - replace global field tensileStrength by tensileStrFac
447      - tensileStrFac can be computed once in S/R seaice_init_varia
448      - fortunately that does not affect any verification results
449    
450    checkpoint65w (2016/05/12)
451    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
452         with ECCO_CTRL_DEPRECATED defined
453    o verification/global_ocean.cs32x15:
454      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
455        with "selectNHfreeSurf=1".
456    o model/src (non-hydrostatic free-surface):
457      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
458        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
459      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
460        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
461        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
462        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
463      - Update output (changes at machine truncation level) of verification exp:
464        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
465        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
466    o pkg/seaice: ITD code
467      - fix picking up from a single category model by initialising
468        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
469      - split a long warning message in seaice_check_pickup.F into two lines,
470        because NEC SX-ACE cannot deal with the long line.
471    o model/src:
472      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
473    o pkg/seaice:
474      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
475    o pkg/seaice:
476      - add basal stress as parameterisation for grounding ice
477        following Lemieux et al. (2015)
478      - turn on by setting new parameter SEAICEbasalDragK2 to a value
479        larger than 0. Lemieux et al. (2015) recommend 15.
480      - The adjoint complains with extra recomputations so there is also a
481        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
482        order to postpone the problem
483      - compile the new code in lab_sea
484    o verification/halfpipe_streamice:
485      - update both TAF and OpenAD adm output (machine truncation differences)
486    
487    checkpoint65v (2016/04/08)
488    o verification/advect_xz:
489      - increase overlap size from 3 to 4 and add new secondary test for PQM
490        advection scheme (with mono & wino limiter).
491      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
492    o model/src:
493      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
494        added phi0Ref) to set vertical axis origin and phiRef origin;
495        keep Ro_SeaLevel for backward compatibility (with a warning).
496       According to coordinate and fluid type:
497        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
498        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
499        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
500        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
501      - remove Ro_SeaLevel from ATM experiment parameter files;
502      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
503        complement; update output.txt (changes at machine truncation level).
504    o pkg/seaice/seaice_evp.F
505      - simplify computation of deltaZ and zetaZ to simple averaging following
506        Bouillon et al. (2013). This removes a lot of code, but also changes
507        verification experiment lab_sea.hb87 -> updated
508    
509    checkpoint65u (2016/03/14)
510    o pkg/generic_advdiff:
511      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
512        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
513        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
514        testing and not for actual use.
515    o model/src:
516      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
517        origin r = rF(1);
518      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
519        in EOS for height coordinate: enable to include NH Pressure or to use
520        more accurate pressure vertical profile; options not linked to EOS type
521        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
522      - start to implement variable gravity (along vertical): for now, only with
523        z-coords (not even z*).
524      - add Ideal Gas equation of state for height coordinate.
525      - update OpenAD output (affected at machine truncation level) of exp:
526        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
527    o pkg/exf:
528      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
529        of exf interpolation (before any rescaling, rotation or interpolation
530        to velocity point) for each field that gets loaded from file. This option
531        identically mimics the input file organization (e.g. record numbers in year
532        by year input files) besides the change in horizontal grid.
533      - add rotateStressOnAgrid run-time switch so that wind stress fields
534        can be provided on the A-grid in zonal/meridional direction and
535        rotated on the fly. This only applies to the case when the exf
536        interpolation is off and rotateStressOnAgrid is false by default.
537    o model/src:
538      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
539        it's also used with pkg/atm_phys) and add few more parameters (but still
540        inactive, src code yet to come)
541    
542    checkpoint65t (2016/02/10)
543    o pkg/atm_phys:
544      - from Ruth Geen: add optical depth dependence on CO2 concentration.
545    o model/src:
546      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
547        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
548        Update output of exp. deep_anelastic (changes at truncation level).
549    o tools:
550      - add a hack in "remove_comments_sed" (used only with TAF) for recent
551        version of OpenMPI (shipped with FC.23): comment out the new header
552        file "mpif-sizeof.h" which causes problems to TAF.
553    o pkg/seaice:
554      - change the termination criterion so that maxits (SEAICElinearIterMax)
555        has an effect
556      - unify iteration parameters for implicit solvers (JFNK and Picard)
557        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
558        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
559        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
560        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
561        SEAICEnonLinTol     replaces JFNKgamma_nonlin
562      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
563      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
564        use with SEAICEuseKrylov
565    o pkg/seaice/seaice_lsr.F
566        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
567        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
568        an effect.
569    o pkg/seaice: add two new parameters
570      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
571        parameter is not in any namelist)
572      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
573        a preconditioner for the non-linear Newton iteration of the JFNK
574        solver
575    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
576      affects some experiments at truncation level:
577      - global_ocean.cs32x15.icedyn (11 digits),
578      - global_ocean.cs32x15.seaice (11 digits),
579      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
580      - also update global_ocean.cs32x15 adjoint and tangent-linear results
581    o pkg/salt_plume & pkg/thsice:
582      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
583        connect salt_plume flux to ATM-OCN coupling pkgs interface:
584       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
585         export to coupler interface) even without compiling pkg/salt_plume ;
586       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
587         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
588    o pkg/dic:
589      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
590        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
591        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
592      - move also update with values from ATM-OCN Coupler in the same new S/R
593        (previously done in ocn_apply_import.F).
594    o tools/adjoint_options:
595      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
596        has been changed on Jan 14, 2016.
597    o pkg/ggl90:
598      - add alternative discretisation of vertical shear (off by default), to
599        compute the mean (@ grid-cell center) of vertical shear compon instead of
600        vertical shear of mean flow (@ grid-cell center).
601      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
602        results on adjacent faces of cubed-sphere grids; this fix the restart.
603    o pkg/atm_compon_interf:
604      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
605        pass last value, stored directly before export to CPL ;
606        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
607      - remove atmSLPr from pickup files (no longer needed for restart)
608    
609    checkpoint65s (2016/01/13)
610    o eesupp & genmake2:
611       - first check for Function ETIME and, if it fails, then check for subroutine
612         ETIME and consistent output; use the appropriate version in timers.F
613    o model/src:
614      - to check restart test, add option to apply EXCH to U,V earlier, just before
615        integr_continuity; turned off by default.
616    o pkg/dic:
617      - remove CPP option USE_ATMOSCO2 (not needed)
618    o tools/tst_2+2:
619      - try to ignore difference between +0 and -0 in binary file, causing test
620        to fail for no good reason.
621    o eesupp & genmake2:
622      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
623        but also check (in genmake2) that test runs and returns meaningful results.
624    o coupler pkgs:
625      Finish implementation of optionally-exchanged variable switches (started on
626       Nov 12) with addition of few more exchanged fields, including 2-way exchange
627       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
628       advection in OCN component; this requires sequential coupling.
629      coupler (pkg/atm_ocn_coupler):
630      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
631        routines (useful for debug).
632      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
633         flux, DIC fields) if corresponding switch is ON.
634      - add option to export RunOff to OCN (to use for DIC river input)
635      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
636      components (pkg/atm_ & ocn_compon_interf):
637      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
638        optionally exchanged fields; add a check & stop in cpl_readparms.F.
639        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
640        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
641      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
642        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
643      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
644      - hold in common block coupler optionally-exchanged variable switch
645        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
646      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
647        this is intended to replace the OCN cplFldtave.* output files (not updated
648        to contain new additional exchanged fields).
649    o pkg/dic:
650      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
651    o pkg/thsice:
652      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
653        and writing of thsice pickup files.
654    o pkg/atm_compon_interf:
655      - move all field individual export-call out of cpl_export_import_data.F
656        into new S/R ATM_EXPORT_FIELDS
657    o pkg/atm_compon_interf:
658      - store state variables (for now, only thSIce fields) just before beeing
659        exported (in cpl_export_import_data.F, like on ocean side) instead of from
660        atm_store_my_data.F like all exported fluxes.
661      - new version of pickup_cpl: write field names into meta file and read meta
662        file to find field postion in pickup. Also only write/read fields meeded for
663        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
664    o pkg/dic:
665      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
666    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
667        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
668        value can be from domain [0,1] to average between the two methods
669    o pkg/atm_phys:
670      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
671        hold fixed in time).
672    
673    checkpoint65r (2015/12/21)
674    o pkg/seaice:
675        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
676        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
677    o pkg/seaice:
678      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
679        when SEAICEscaleSurfStress=.TRUE.,
680      - apply areaW and areaS in S/R seaice_calc_lhs
681    o pkg/atm_phys:
682      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
683        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
684        for individual contribution (convection, LSC cond, radiation)
685      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
686        information); activated with: solar_exponent=0. and wv_exponent=-1.
687    o pkg/ggl90:
688      - within IDEMIX add upper limit for horizontal group velocity to
689        avoid instability problems in the explicit horizontal diffusion term for
690        long time steps or high resolution
691    o pkg/diagnostics:
692      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
693        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
694    o testreport:
695      - remove "-v" (verbose option) in default mpirun command.
696    o pkg/seaice/seaice_growth:
697      - catch potential division by zero in ITD code, does not change
698        verification results
699    o pkg/ecco:
700      - retire old codes to the Attic. The calls to retired functions are
701        left in a commented form in case they ever need to be re-activated.
702      - ecco_check.F: issue warning if any old CPP option is
703        defined that corresponds to retired codes -- then stop.
704    o pkg/atm_compon_interf:
705      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
706        coupler: use last time-step value instead of average over cplSendFrq_iter
707        time-step, similar to what is done for seaIceMass.
708        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
709    o eesupp & genmake2:
710      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
711        <= remove until a fix is found for some ifort version on ia32 machine.
712    o pkg/seaice/seaice_evp:
713      - refine residual computation
714    
715    checkpoint65q (2015/11/18)
716    o pkg/seaice/seaice_evp:
717      - fix residual computations so that they no longer affect the actual
718        simulation code
719      - fix seaice_readparams to be able to actually set new parameters
720        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
721    o model/src:
722      - fix wrong truncation (single prec) from "FLOAT" function in expressions
723        like: deltaT*FLOAT(myIter) when myIter is large:
724         a) replaced by DFLOAT (if not seen by TAF);
725         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
726    o pkg/aim_v23:
727      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
728        when pickupSuff is set ; do write rolling pickups + at the end of the run.
729    o pkg/atm_ocn_coupler + ocn_compon_interf:
730      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
731        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
732        add corresponding call in DO_OCEANIC_PHYS.
733    o coupler pkgs:
734      Start a new way to set-up optionally-exchanged variables (previously, only
735       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
736       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
737       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
738       compononent param default can be set accordingly).
739      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
740       but rather applies to a group a fields (going both ways like for DIC)
741       and corresponds to an option of coupling config.
742      coupler (pkg/atm_ocn_coupler):
743      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
744        and read namelist directly (without eessup S/R calls) instead of
745        in the very un-flexible old way, 1 param per line, in fixed order;
746      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
747        cleanly in CPL_CHECK_CPLCONFIG
748      - add new coupling-exchange selectors (some not yet active) including
749        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
750                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
751      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
752        component ; called directly from coupler.F, after comp. registrations;
753      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
754         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
755          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
756      components (pkg/atm_ & ocn_compon_interf):
757      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
758        CPP header file in all pkg source files.
759      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
760        ATM/OCN_CHECK_CPLCONFIG;
761      - add error-counter to track errors (e.g., in "data.cpl") and to stop
762        cleanly in ATM/OCN_CHECK_CPLCONFIG;
763      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
764        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
765        before PACKAGES_READPARMS;
766      verification/cpl_aim+ocn/:
767      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
768        "data.cpl" for coupler (in input_cpl).
769    o eesupp/inc:
770      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
771        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
772        to always cumulate tile local-sum in the same order (still uses
773        MPI_Allreduce like standard code).
774      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
775        that are now identical to standard version (in eesupp/inc).
776    o pkg/shelfice:
777      - add SHELFICETransCoeffTFile for initializing spatially varying
778        heat and salt transfer coefficients
779    o pkg/atm_compon_interf & ocn_compon_interf:
780      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
781        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
782      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
783    o pkg/atm_ocn_coupler:
784      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
785    o pkg/rbcs:
786      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
787        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
788      - add a short report (to STDOUT) about RBCS-mask settings.
789    
790    checkpoint65p (2015/10/23)
791    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
792        there is no adjoint test for EVP, we don't know what it does to the adjoint
793        solution, but at least there are no more recomputation warnings left
794    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
795        a chance of giving the same results as a fully converged VP (JFNK) solver
796    o tools/adjoint_options/adjoint_diva:
797      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
798    o pkg/streamice:
799      - spotted bug in streamice_driving_stress using dyG where should have been dxG
800    o pkg/exf:
801      - remove STOP statement that prevented to use wind or (wind-)stress
802        interpolation for constant-in-time forcing fields (wind/stress period = 0).
803    o pkg/seaice:
804      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
805        5 additionals 2D fields and 6 new store directives
806      - change logic in seaice_readparms.F: EVP code can now be turned on in
807        various ways, setting SEAICE_deltaTev is no longer required,
808        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
809        or SEAICEaEVPcoeff
810    o pkg/shelfice/shelfice_thermodynamics.F
811      - redefining uLoc/vLoc to u/v, instead of 2u/v
812    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
813      - this is an intermediate state of a truely converging EVP that has
814        the potential of outperforming implicit VP methods, I do not recommend
815        using it yet.
816      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
817        and all parameters are hardwired
818      - for convergence it still requires very smooth regularisations, that means,
819        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
820        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
821        specific averaging appears to be required, still subject to tuning
822      - still needs cleaning and I need to turn parameter into runtime parameters
823      - add code to compute and print residuals of iteration, compile with
824        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
825    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
826      that entered with r1.54 on Sep04, 2015, -> update results
827    
828    checkpoint65o (2015/09/14)
829    o pkg/mom_vecinv & mom_common:
830      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
831        called from there.
832      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
833        allows to use Vector-Invariant form in deep atmos and anelastic formulation
834    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
835      and Koenig-Beatty+Holland (2012)
836      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
837      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
838      - requires an extra input argument for S/R seaice_calc_viscosities
839      - tensileStrength's depth dependence is different from Itkin et al. (2015)
840        (to be changed and played with, for now exponential)
841    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
842      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
843        by AREA according to Connelly et al. (2004), JPO.
844      - For EVP and the LSR solver, the implicit part of the drag term is
845        the only non-zero term in the denominator when there is no ice (which
846        prevented running the model with zero ice-ocean drag). If
847        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
848        (or zero main diagonals BU/BV) which need to be caught. A practical
849        consequence is that for open water, the momentum equation reduce
850        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
851        they happen to be zero, often leading to a non-zero solution over
852        open water.
853    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
854        efficient EVP method.
855      - introduce area-weighted averages for e12 (analogously to
856        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
857        remain, but also changing the order of terms in the previous average
858        changed the results as much) -> update experiment
859      - add SEAICE_DELTA_SMOOTHREG code
860      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
861        TEM-code
862      - adjust loop bounds so that only required fields are computed
863      - add new averaging code for zetaZ/deltaZ (again similar to
864        seaice_calc_viscosities.F), inactive by default for now (will change
865        results again), but will replace old code eventually
866    o eesupp/src:
867      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
868        to always cumulate tile local-sum in the same order
869        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
870        Still uses MPI_Allreduce (like standard code) but on array of tiles
871        and should be faster than GLOBAL_SUM_SEND_RECV code.
872      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
873        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
874      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
875         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
876         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
877         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
878         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
879    
880    checkpoint65n (2015/07/29)
881    o pkg/thsice:
882      - add a warning when used with pkg/aim but without updating SST
883        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
884    o pkg/offline:
885      - change where Offline-Fields are loaded, from load_fields_driver.F to
886        directly within FORWARD_STEP, just after updating iter number and time;
887      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
888        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
889       These changes allow:
890        a) to recover exactly on-line results using deltaToffline=deltaTClock,
891        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
892        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
893        time-step, both with GM & KPP files and with recomputing these fields;
894        b) no needs to switch on staggerTimeStep anymore;
895        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
896      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
897    o pkg/offline:
898      - change (rarely used) offset-iteration parameter to an offset time (in s):
899        can easily recover previous offset-iter effect by setting offset-time
900        (offlineTimeOffset) to offset-iter x deltaToffline;
901      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
902        in KPP as part of surface buoyancy forcing) in offline run.
903      - fix ptracers KPP non-local term in the case where KPP is re-computed.
904    o OpenAD
905      - Adding preliminary ggl90 test to OpenAD verification.
906        Config. with ggl90 currently diverges after 64 time steps
907        so will need more work to become more stable
908      - Adding preliminary kpp test to OpenAD verification.
909        required small tweakes in kpp_routines.F
910      - Merge and update from Krishna Narayanan's contrib area:
911        * Add one variable for preliminary OpenAD DIVA
912        * Add replacement time-stepping for OpenAD DIVA
913        * genmake2 flag -diva (but only for OpenAD; preliminary)
914        * required modifs for OAD_support
915        successful preliminary test for tutorial_global_oce_biogeo/
916    o pkg/seaice:
917      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
918      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
919        delta with a smooth function in s/r seaice_calc_viscosity
920        (no effect on EVP)
921      - rename local suffix "sqr" into "sq" for more consistent variable names
922    o pkg/seaice:
923        add new parameter SEAICE_deltaMin that is used ***only***
924        for regularizing Delta (and nothing else, like the parameter
925        which is also used for all sorts of things SEAICE_EPS).
926        Defaults to SEAICE_EPS for backward compatibility only.
927    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
928        the wrong key by inialising it before use -> fixes a recomputation
929        problem but does not fix the gradient
930    o pkg/layers:
931      - move resetting of flux arrays to outside the iLa loop
932        (this caused layers_diapycnal to not work with more than one layer coord.)
933      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
934    o pkg/layers:
935      - remove from common block 3D layers fields (used to diagnose transport
936        in tracer coords) and declare them as local arrays in layers_calc.F
937    o pkg/seaice:
938      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
939        in lab_sea forward experiment (changes results -> updated)
940      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
941    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
942       computations; for SEAICE_VECTORIZE_LSR
943      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
944        sweep to the outside,
945      - remove store directives and add "CADJ loop sequential" directives
946        in analogy to model/src/solve_tridiagonal.F
947      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
948        boundaries to yield more readable code. This has also the charming side
949        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
950        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
951        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
952        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
953        an additional option)
954       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
955       but the adjoint gradients (which are affected by this change) still explode.
956    o coupler (atm & ocn _compon_interf):
957      - avoid using Exch2 IO mapping if not suitable.
958    
959    checkpoint65m (2015/06/15)
960    o pkg/layers:
961      - clean-up old parameters setting (from Sep 2012):
962        + remove old parameters setting from common block (declared locally);
963        + stop if any old parameter is mixed with new parameters;
964        + check for valid or consistent parameter setting (e.g., layers_name)
965      - check that layers_bounds for Pot.Density are in the right range;
966        this is supposed to catch un-updated setting after recently shifting
967        potential density field "prho" by -1000 (now in "sigma" scale).
968    o pkg/layers:
969      - Added missing call to layers_fill for keeping track of tottend in
970        pkg/diagnostics/diagnostics_fill_state.F
971    o pkg/layers:
972      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
973        of diapycnal fluxes
974    o pkg/layers:
975      - reverted changes to interpolation to previous treatment; there
976        was never actually a problem
977    o pkg/layers:
978      - fix interpolation of layers tracers in the presence of partial cells
979      - add lots of new functionality to compute water mass transformation
980        (enabled by CPP flag LAYERS_THERMODYNAMICS)
981      - add new calls from main code (diags_oceanic_surf_flux.F,
982        thermodynamics.F, impldiff.F) and gad to save the necessary fields
983        for layers_thermodynamics calculations
984    o pkg/ptracers:
985      - add capability of stepping a passive tracer forward without advection
986        by setting PTRACERS_advScheme to 0.
987    o pkg/diagnostics:
988      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
989    o pkg/layers:
990      - shift potential density field "prho" by -1000 for density layer averaging so
991        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
992        Note that density bin boundaries (layers_bounds in data.layers) have
993        to be set accordingly (i.e., shifted, in sigma scale).
994    o pkg/layers:
995      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
996      - fix calculation of layer non-weighted velocity and layer probability
997      - add diagnostics for pot.density used for layer averaging
998    o pkg/seaice:
999      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
1000        positiveness, modify a few comments and improve variable names,
1001      - the changed computation of deltaC affects most seaice-related
1002        experiments at the truncation level.
1003        seaice_itd.thermo is affected by far the most, with
1004        only 7 digits of agreement remaining; update experiments.
1005    
1006    checkpoint65l (2015/05/04)
1007    o pkg/shelfice:
1008      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
1009        factor drKp1 to zero where it is negative (ie. do not use
1010        SHELFICEBoundaryLayer if hFacC>1)
1011      - the same for factor drLoc in shelfice_forcing.F
1012    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
1013        with modules in ptracers, when using testreport option "-small_f"
1014    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
1015      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
1016    o verification/testreport
1017      - add new option -small_f
1018        with this option testreport first makes the target small_f (*.f files)
1019        before running make (all). This is useful for explicit inlining when
1020        all sources need to be full available.
1021    o pkg/exf/exf_interp.F:
1022        remove previous changes related to reverse (decreasing) input grids latitude
1023    
1024    checkpoint65k (2015/04/01)
1025    o pkg/ecco:
1026        fix missing cosphi initialization; use eccoiter in place of optimcycle;
1027        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1028        instead of active read/write
1029    o pkg/ctrl:
1030        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1031        instead of active read/write.
1032    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
1033        return if .NOT.useAUTODIFF
1034    o pkg/seaice: add CPP brackets (cost function related).
1035    o model/src:
1036        add useAUTODIFF run time switch.
1037    o pkg/exf/exf_interp.F:
1038        add code to allow input grids with latitude starting in the north (i.e. when
1039        j=1 corresponds to northern edge of field); modify global_with_exf to test
1040        this feature.
1041    o verification/testreport:
1042      - replace "grep -A3" with POSIX conformal sed command, because there are
1043        implementations of grep that cannot do contextual searches
1044      - replace "cat -n" by "nl" (two occurrences), because not all implementations
1045        of "cat" have the option "-n"
1046    o model/src:
1047        add new file gsw_teos10.F that contains 3 functions, more or less a copy
1048        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
1049        convert from conservative to potential temperature. For now they are not
1050        called anywhere.
1051    o pkg/ggl90: make "useIDEMIX" useful
1052      - re-organize code in s/r ggl90_calc a little to move computations that
1053        are different for idemix into separate loops (changes verification
1054        experiment idemix at truncation level, 12 digits remain -> updated)
1055      - requires 2 new 2D fields KappaM, verticalShear
1056      - make hFacI and recip_hFacI local 3D variables that are passed to
1057        s/r ggl90_idemix
1058      - fix and improve some comments
1059    
1060    checkpoint65j (2015/02/25)
1061    o pkg/openad
1062      - synchronize seawater.F with version in model/src: replace routine
1063        body of sw_temp by calling sw_ptmp and fix/add a few comments.
1064    o pkg/mnc:
1065      - change default value of pickup_read/write_mnc params to FALSE
1066        (since few features are missing in reading MNC pickup files).
1067    o model/src:
1068      - change default (background) vertical diffusivity for salt to be the
1069        temperature (background) vertical diffusivity.
1070      - change background vertical diffusivity in vertical mixing pkgs ggl90,
1071        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
1072        This makes ptracers default diffusivity (that uses salt diffKr) more
1073        consistent with vertical mixing schemes.
1074    o verification/testreport:
1075      - fix typo in "-pcls" option ;
1076      - put temp files in /tmp (instead of in local dir)
1077      - add option "-ncad" to use genmake2 new option "-nocat4ad"
1078      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
1079    o pkg/ggl90 (idemix code):
1080      - apply few fixes ; add some missing "_d 0" ; update output of exp.
1081        global_ocean.90x40x15.idemix
1082    o OpenAD
1083      - enable active file I/O and begin removal of work-around code
1084        for OpenAD for handling control variables (memory vs. active files)
1085      - new CPP options file OPENAD_OPTIONS.h
1086      - revert to genarr2d gradient check for hs94.1x64x5
1087      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1088      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1089    o tools/genmake2:
1090      - add option for an alternative Makefile (from Martin) where multiple
1091        source files are sent to TAF (instead of all in one file).
1092    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1093      - code provided by Carsten Eden as an extension of ggl90
1094      - so far the code is turned on within ggl90 by setting a CPP-flag at
1095        compile time; a runtime flag implementation is not yet complete
1096      - tested in new verification experiment global_ocean.90x40x15.idemix
1097    o verification:
1098      - reduce length of the AD test run by half for experiments
1099        global_ocean.cs32x15 (std + thsice) and isomip
1100      - enable active file I/O for OpenAD, adjust verifications accordingly
1101      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1102    o verification/testreport:
1103      - fix two non-POSIX sed statements so that there are no error messages
1104        on Mac OS X
1105      - replace hostname -s with hostname | sed 's/\..*$//'
1106    o model/src/seawater.F:
1107      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1108        (following the matlab code), which would have avoided the bug caught
1109        by Matt (see below) in the first place
1110    o pkg/shelfice:
1111      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1112        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1113      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1114        ice-shelf case (i.e., within surface level).
1115      - add config summary in shelfice_check.F
1116      - remove global variable recip_SHELFICElatentHeat and replace by a local
1117        variable recip_latentHeat
1118      - introduce diagnostics for friction velocity uStar (in case of
1119        SHELFICEuseGammaFrict)
1120      - change verification experiment isomip.htd:
1121        + start from pickup (as input_ad at nIter0=8640)
1122        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1123        + test SHELFICEuseGammaFrict = .TRUE.
1124        + test SHELFICEadvDiffHeatFlux = .TRUE.
1125    o model/src:
1126      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1127        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1128        update output of experiments global_with_exf.yearly and isomip (all 6).
1129    o pkg/shelfice:
1130      - change setting of kTopC to also be zero where there is no ice-shelf.
1131      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1132        ice-shelf is.
1133      - first attempt to get RealFreshWaterFlux effects: for now, only without
1134        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1135    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1136      for thermodynamic calculations
1137      - because of divisions of the type 7/7 not exactly equal to 1, this change
1138        affects results of some verification experiments by up to 4 digits:
1139        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1140        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1141        adjoint: lab_sea, lab_sea.noseaicedyn
1142        -> updated
1143    
1144    checkpoint65i (2015/01/23)
1145    o model/src:
1146      - change units of frictionHeating field from W to W/m^2
1147      - fix bug in frictional heating from stratospheric drag in
1148        S/R ATM_PHYS_TENDENCY_APPLY_V
1149      - with synchronous time-stepping: move resetting to zero of frictionHeating
1150        field from load_fields_driver.F to thermodynamics.F ;
1151      - add diagnostics for frictional heating.
1152    o model/src & gmredi K3D:
1153      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1154      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1155      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1156        and name in pickup file).
1157      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1158    o model/src:
1159      - move (from ini_forcing.F) initialisation of all arrays in header file
1160        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1161        (since Nov 2012) with option selectAddFluid=1.
1162    o pkg/shelfice:
1163      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1164      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1165    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1166    o pkg/seaice: two new runtime parameters:
1167      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1168        long overdue
1169      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1170        parameterization of tensil stress for fast ice (does not do anything yet)
1171    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1172        for LSR: move checking overlaps out of JFNK-if-block
1173    o pkg/atm_phys:
1174      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1175        new S/R ATM_PHYS_DYN2PHYS.
1176      - fix level height for Linear Free-Surf case (to be consistent with
1177        fixed-in-time pressure levels).
1178    o pkg/mom_common (bottomdrag):
1179      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1180        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1181        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1182    o pkg/shelfice (u/v_drag):
1183      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1184      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1185        (now similar to shelfice_u_drag.F)
1186      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1187        from mom_vecinv.F (similar to mom_fluxform calls).
1188    o pkg/mom_common (bottomdrag):
1189      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1190      - add options for alternative discretisation of velocity norm in quadratic
1191        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1192        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1193        improves when averaging only the other component (e.g. vVel for U bottom
1194        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1195      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1196        friction (no-slip BC) thus getting the true distance from the bottom;
1197        off by default since this also reduces model stability (explicit bottom
1198        friction). Changes produce different machine truncation with linear-drag
1199        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1200        front_relax (bvp & mxl, 10 & 11 digits).
1201    o model/src & mom pkgs:
1202      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1203        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1204      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1205        just copy level Nr value to level Nr+1.
1206    o doc:
1207      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1208    o pkg/shelfice:
1209      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1210        SHELFICE.h: move array shelficemass to init_varia, initialise
1211        from array shelficemassinit, which is set in init_fixed and
1212        has option to be set from file; introduce array
1213        shelficeMassDynTend array, set thru file in init_fixed
1214      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1215        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1216        pkg/streamice
1217      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1218        SHELFICEMassStepping = .true.
1219      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1220    
1221    checkpoint65h (2014/12/17)
1222    o verification/global_ocean.90x40x15, global_ocean_ebm:
1223      - update to generic controls.
1224    o pkg/ctrl:
1225      - ctrl_map_ini_genarr.F: test for igen>0
1226      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1227      - move gentim2d part of ctrl_map_ini_genarr.F to
1228        new separate routine : ctrl_map_ini_gentim2d.F
1229      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1230        add time variable weights and cyclic controls (time mean,
1231        seasonal cycle, etc) capabilities to gentim2d
1232    o pkg/ecco:
1233      - move reading of error, conversion to weights from
1234        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1235    o global_oce_llc90, cs32:
1236      - activte sbo.
1237      - CTRL_SIZE.h : add maxCtrlProc.
1238      - activate the new genctrl capabilities.
1239      - update following reorganization of global_oce_input_fields.tar.gz  
1240    o pkg/ctrl/ctrl_ad_diff.list:
1241      - add missing ctrl_init_rec.f
1242    o tools/OAD_support/keepOriginal:
1243      - add ctrl_init_rec.F
1244    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1245      - avoid recomputations of xx_gentim2d_dummy.
1246    o momentum diagnostics:
1247      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1248        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1249    o pkg/seaice/seaice_lsr.F:
1250      - fix computation of BU/BV, make sure they are non-zero, only necessary
1251        for cubed sphere exchanges and SEAICE_OLx/y>0.
1252        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1253    o verification/global_ocean.cs32x15/input.seaice
1254      - add test for strong implicit coupling and restricted addtive Schwarz
1255        methods for LSR
1256      - update results/output.seaice.txt
1257    o verification/tutorial_global_oce_biogeo:
1258      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1259        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1260        update output_adm,_oadm,_tlm.txt
1261    o pkg/dic:
1262      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1263      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1264        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1265    o verification/tutorial_global_oce_biogeo:
1266      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1267        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1268        update output_adm,_oadm,_tlm.txt
1269    o eesupp/src:
1270      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1271        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1272    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1273      LSR (following Hutchings et al. 2004)
1274      - introduce zetaZ as a global variable (requires adjustments in
1275        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1276        in seaice_calc_viscosities.F
1277      - new flag SEAICEuseStrImpCpl (default off)
1278      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1279        momentum equations
1280      - JFNK-solver (preconditioner) adjusted to allow using this method
1281        (where it does not have any positive effect)
1282    o pkg/seaice
1283      - add overlap for restrictive additive Schwartz method also to LSR, but
1284        turn it off by default (because it only seems to work for non-cubed
1285        sphere/llc topologies)
1286    o pkg/autodiff
1287      - add extra exchanges in addummy_in_steppging also for mnc output
1288    o pkg/seaice:
1289      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1290        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1291    o pkg/obcs:
1292      - add option to specify domain-connected piece Id along OB though files
1293        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1294      - modify obcs_diag_balance.F to process each connected-part separately;
1295        exclude OB where Id = 0 but keep the full divergence there (-> constant
1296        Psi along this portion of OB and all inflow derived from grad(Phi))
1297      - add example of OB-conect files in verification/so_box_biogeo/input.
1298    o pkg/diagnostics:
1299      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1300      a) use non zero matrix element across OB and solve for Phi 1 grid point
1301         outside OB (i.e, where tracer OBCS are applied).
1302      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1303         velocity across OB, spread it uniformly along the OB in the RHS.
1304    
1305    checkpoint65g (2014/11/19)
1306    o pkg/diagnostcis:
1307      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1308    o pkg/my82,pp81,kl10:
1309      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1310        field diffKr as background diffusivity to set minimum diffusivity value.
1311    o pkg/seaice:
1312      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1313        Bouillon et al 2013)
1314      - add SEAICE_evpAlpha/Beta to namelist
1315      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1316        involve trivial re-ordering of divisions/multiplications that should not
1317        have any effects, but ... they do change the results of lab_sea.hb87 so
1318        that only 2 digits of agreement remain, in line with the general
1319        instability/fragility of the evp-code. For now, I do not care and just
1320        update the verification experiment
1321    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1322      - remove xx_genarr2d_numsmooth etc
1323      - use xx_genarr2d_preproc etc instead
1324      - carry out smooth_correl2D at initialization stage rather than during
1325        time stepping.
1326      - get smoothOpNb from xx_gentim2d_preproc
1327    o global_oce_cs32 :
1328      - add test of generic ecco capabilities.
1329    o pkg/exf/exf_getsurfacefluxes.F :
1330      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1331    o pkg/ctrl,ecco :
1332      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1333        is defined.
1334    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1335    o model/src:
1336      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1337        diffusivity (background) is specified but ignored.
1338    o verification:
1339      - in testreport, convert hostname to lower case for default output dir name
1340    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1341    o pkg/dic: add modifications from Hajoon:
1342      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1343      - light attenuation: add self-shading effect by climatological Chlorophyll
1344        (read from file).
1345    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1346        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1347    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1348        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1349        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1350        approach where CPP_OPTIONS.h includes an omnipotent
1351        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1352    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1353        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1354    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1355        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1356        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1357    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1358      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1359      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1360      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1361      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1362    o pkg/ctrl,ecco,exf :
1363      - remove variables associated with NON-generic costs,
1364        unless ECCO_CTRL_DEPRECATED is defined.
1365      - remove NON-generic NON-obcs controls,
1366        unless ECCO_CTRL_DEPRECATED is defined.
1367    o pkg/ctrl : added ctrl_local_params.h
1368    o pkg/ecco : added ecco_local_params.h
1369    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1370        experiments, which will progressively be removed once the
1371        experiments are revised to use only generic controls/costs.
1372    
1373    checkpoint65f (2014/10/13)
1374    o pkg/ctrl, ecco, seaice : minor changes in headers

1381        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1382      - cost_gencal.F (new) : determine filnames and records.
1383      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1384      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1385        and exploit the above functions leading to more compact code.
1386      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1387      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1388        using_ers, using_gfo, using_mdt is now only defined within gencost)
1389    o pkg/ecco: extend generic cost capabilities
1390      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1391        capabilities via gencost_preproc (+ _c,_i,_r related params),
1392        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1393        gencost_outputlevel arguments to cost_generic
1394      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1395        and active_read, making room for gencost_preproc to take effect.
1396        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1397      - pkg/ecco/cost_generic.F :
1398        compute and store misfit maks*(model-data) in localdif that is
1399        then used in cost and for output, output misfit if outlev.GT.0
1400      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1401        rather gencost_barfile for deciding whether to write barfile
1402      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1403      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1404        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1405      - pkg/ecco/ecco_summary.F : report gencost variables
1406      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1407    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1408    o pkg/ecco: internal re-organization
1409      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1410        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1411        mv relevant variables definition from ecco_cost.h to ecco.h,
1412        make sure gencost routines only include ecco.h)
1413      - throughout : add missing CCP switches, rm unused variables,
1414        and rm un-necessary CPP switches
1415      - throughout gencost routines : replace modelstartdate with
1416        gencost_startdate when needed
1417      - cost_bp_read.F : use arguments, instead of common blocs
1418        so that it can be used also by (new) cost_gencost_bpv4.F
1419      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1420      - ecco_phys.F : compute etanFull
1421      - ecco_readparms.F : rename using_topex as using_tpj, add
1422        bpv4-grace to gencost list, initialize added parameters
1423      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1424    
1425    checkpoint65e (2014/09/28)
1426    o pkg/obcs:
1427      - replaced the just-added CPP options with run-time variables
1428        (see pkg/obcs/OBCS_PARAMS.h for details)
1429    o pkg/obcs:
1430      - add additional CPP options for sponge boundary layers
1431        (see pkg/obcs/OBCS_OPTIONS.h for details)
1432    o pkg/atm_phys:
1433      - implement simple (obliquity only, assuming circular planet orbit)
1434        seasonal cycle for incoming insolation ; used when run-time parameter
1435        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1436    o pkg/exf, pkg/ecco, pkg/ctrl:
1437      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1438      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1439      - implement gentim2d for xx_tauu, xx_tauv
1440    o pkg/ctrl, pkg/ecco :
1441      - fix and complement the generic controls implementation
1442    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1443        pkg/shelfice/shelfice_thermodynamics.F,
1444        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1445        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1446      - add weight in CTRL_GET_GEN calls
1447    o pkg/ctrl :
1448      - ctrl_get_gen.F : add weight as input parameter, and apply
1449        it directly rather than using smooth_correl2Dw (to be retired).
1450      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1451    o pkg/ctrl :
1452      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1453        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1454      - re-activate ctrl_summary (call in ctrl_init.F)
1455    o pkg/ctrl/ctrl_cost_gen.F :
1456      - fix CCP brackets, remove un-necessary myiter, mytime

1461      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1462    
1463    checkpoint65d (2014/09/15)
1464    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1465      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1466        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1467    o pkg/ctrl/ctrl_map_ini_genarr.F :
1468      - remove compilation failure
1469      - replace hard coded example
1470      - use ctrl_map_ini_gen2D, 3D
1471    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1472      - on/off switch based upon xx_genarr2d_weight,3d
1473    o src/packages_init_variables.F :
1474      - regroup pkg/estimation calls
1475      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1476        (moved to ctrl_init_variables)

1487      - remove ECCO_PHYS (mv to ecco_init_varia)
1488      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1489    o ecco/ecco_ad_diff.list :
1490      - add ecco_init_varia.f
1491    o ecco/ecco_init_varia.F
1492      - new routine
1493    o pkg/streamice:
1494      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1495        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1496      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1497    o pkg/generic_advdiff:
1498      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1499    o pkg/exf:
1500      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1501         xxg_precip capability
1502      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1503    o pkg/ctrl:
1504      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1505    o model/src/load_fields_driver.F :
1506      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1507        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1508    o OpenAD verification experiments:
1509      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1510        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1511        for now, only in pkgs used in OpenAD verification experiments.
1512      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1513        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1514        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1515        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1516    o OpenAD verification tests:
1517      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1518      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1519        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1520      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1521        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1522    o model/src & generic_advdiff:
1523      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1524        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1525        dynamics requires valid tracer forcing only over tile interior but, for
1526        some diagnostics, may need to extend it over 1 point in tile halo region.
1527      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1528        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1529        setting in temp/salt/ptracer_integrate.F
1530    o pkg/dic:
1531      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1532        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1533        in gchem_forcing_sep.F
1534    o pkg/autodiff & obcs:
1535      - add storage of current OB values for U & V (was already done for T & S).
1536    
1537    checkpoint65c (2014/08/30)
1538    o pkg/dic:
1539      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1540        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1541        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1542    o verification:
1543      - new experiment testing OBCS and DIC pkgs, using params & output from
1544        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1545        passage: take OBCS from the last year of a 2 yrs simulation and initial
1546        conditions from t=1.yr while keeping the same forcing.
1547    o model/src:
1548      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1549        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1550    o pkg/diagnostics (Stats-Diags):
1551      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1552        a) refine region where stats are computed, excluding where arrhFac=0 ;
1553        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1554        c) extend regional stats over the region edges (for U or V pt location).
1555    o pkg/gchem:
1556      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1557        pkg/dic is currently changing/updating ptracers values beyond the OB).
1558    o verification (hs94):
1559      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1560        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1561        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1562        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1563    o pkg/ptracers:
1564      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1565        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1566      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1567        with AB-2 code (so that it get tested).
1568    o model/src:
1569      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1570        with AB-2 code (previously only available with AB-3 code).
1571        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1572        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1573        there, by calling CYCLE_AB_TRACER).
1574    o pkg/generic_advdiff:
1575      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1576        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1577        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1578        S/R temp/salt/ptracers_integrate.F
1579    o model/src & pkg/ptracers:
1580      - remove common block variables gT,gS (in DYNVARS.h), except when
1581         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1582      - remove common block variable gPtr.
1583    o model/src & pkgs:
1584      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1585         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1586         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1587         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1588      + change accordingly all calling S/R.
1589      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1590        in S/R temp/salt/ptracers_integrate.F
1591    o pkg/seaice:
1592      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1593        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1594      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1595        in seaice_lsr
1596      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1597        in s/r seaice_lsr_calc_coeffs
1598    o pkg/mdsio:
1599      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1600        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1601        too long (e.g., > MAX_LEN_FNAM/2 )
1602    
1603    checkpoint65b (2014/08/12)
1604    o pkg/matrix:
1605      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1606    o model/src:
1607      - fix initialisation of geothermalFile; compile geothermal-flux code in
1608        natl_box verification experiment.
1609    o model/src & pkg/down_slope:
1610      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1611      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1612        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1613        results at machine truncation level: update output of experiments
1614        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1615    o pkg/diagnostics (Stats-Diags):
1616      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1617        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1618        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1619        times (but Min,Max and StD are still wrong).
1620    o model/src:
1621      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1622        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1623    o model/src:
1624      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1625        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1626        arrays are already updated while adjustments (filters, conv.adjustment) are
1627        still applied later, in S/R TRACERS_CORRECTION_STEP.
1628    o model/src:
1629      - store in common bloc array "rhoInSitu" the virtual potential temperature
1630        anomaly that is used to compute geopotential: this make the atmos code
1631        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1632    o pkg/seaice/seaice_lsr.F
1633      - rename integer variable ilcall to ipass (that's what it is called
1634        in the residual diagnostics
1635      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1636        default) for improved non-linear convergence of the first few steps
1637      - adjust a few comments and add new ones to explain some of the store
1638        directives
1639    o pkg/generic_advdiff (& ptracers):
1640      - re-work the code to check for valid advection scheme and for minimum
1641        size of overlap (now stored in local common bloc in gad_advscheme.F)
1642    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1643      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1644      - add an auxilliary variable "bet" and fix store directives and keys in
1645        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1646        less exact gradients in my tests); but there are still
1647        recomputation warning (although gradients are sort of OK), when
1648        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1649        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1650      - update verification experiments lab_sea.
1651      - change some comments in S/R seaice_calc_viscosities
1652    o model/src:
1653      - if staggerTimeStep=T, always apply exchange to velocity field in
1654        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1655        (independent of using multi-dim advection or not); no effect on FWD run
1656        but affects AD results (at machine truncation level): update output of
1657        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1658        and isomip (oad: 12.d).
1659    o pkg/generic_advdiff:
1660      - stop if doAB_onGtGs is set to FALSE but ignored
1661      - refine warning related to stability of tracer time-stepping
1662        regarding internal wave dynamics.
1663      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1664        on staggerTimeStep & implicitIntGravWave (will now get a warning
1665        if potentially unstable).
1666    o pkg/kl10:
1667      - add new pkg "kl10" for mixing due to internal wave breaking, from
1668        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1669        (contribution from Jody Klymak), tested in verification experiment
1670        verification/internal_wave/input.kl10/
1671    o isomip experiment:
1672      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1673        (input.htd) and update the output.
1674    o cd_code experiments:
1675      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1676        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1677        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1678        update the corresponding output.
1679    o pkg/seaice:
1680      - reduce the number of include files and store directives in
1681        S/R seaice_lsr_tridiagu/v
1682      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1683        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1684        get rid off one store directive (a TAF bug?)
1685      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1686        S/R seaice_lsr_tridiagv to change the loop range for consistency
1687      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1688      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1689        S/R seaice_lsr_tridiagu/v (requires update of
1690        offline_exf_seaice/input.dyn_jfnk)
1691    
1692    checkpoint65a (2014/07/27)
1693    o model/src:
1694      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1695        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1696        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1697        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1698    o model/src:
1699      - collect momentum forcing tendency into local 2-D array (passed as argument
1700        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1701        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1702        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1703      - collect T & S forcing tendency into local 2-D array (passed as argument to
1704        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1705        affects results at machine truncation level (e.g., ocean: if using
1706        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1707        correction due to vertical advection).
1708      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1709        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1710        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1711        obcs_ctrl (ad & fwd grd @ 12 & 7).
1712    o pkg/ptracers & diagnostics:
1713      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1714        title (to avoid some unexpected truncation); sort out ptracers diags units.
1715      - collect ptracer forcing tendency into local 2-D array (passed as argument
1716        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1717    
1718    checkpoint65 (2014/07/18)
1719    o pkg/fizhi:
1720      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1721        affects results at machine truncation level. Update output of experiments
1722        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1723    o pkg/seaice: more clean up
1724      - rename TAF common block tapes to be more consistent and remove
1725        unnecessary duplicates
1726      - add store directives to remove more recomputations, but use smaller
1727        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1728        The idea behind this flag is to reduce the memory footprint when the
1729        adjoint of the LSR is not required. As of now, defining the flag
1730        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1731        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1732        For experiment offline_exf_seaice, this means on a linux box with gfortran
1733        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1734        this experiment):
1735        > size mitgcmuv_ad
1736        text    data        bss     dec        hex
1737        5100659 1216  220458952  225560827  d71c8fb
1738        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1739        but only a moderate increase of 36% for global_ocean.cs32x15:
1740        text    data        bss     dec        hex
1741        6695027 1648 1014578664 1021275339 3cdf6ccb
1742        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1743      - note: there are still recomputations in global_ocean.cs32x15 and
1744        offline_exf_seaice and the gradient agreement changes (gets a
1745        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1746      - in general, the AD gradients still are wrong
1747    o OpenAD
1748      - clean up code_oad/ directories somewhat by moving files
1749        dontCompile, dontTransform, keepOriginal to OAD_support/
1750    o model/src:
1751      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1752        (not currently tested): add dissipation terms before NLFS rescaling of
1753        tendencies (previously done after).
1754    o pkg/diagnostics:
1755      - write stats-diags in ascii file with more digits (same as in monitor).
1756    o pkg/down_slope:
1757      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1758        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1759    o model/src:
1760      - new file "apply_forcing.F" containing all the code previously in
1761        external_forcing.F, but with new argument list: pass, as new argument,
1762        the current level tendency array to update (instead of a direct update
1763        of the common bloc array). Change the corresponding calls.
1764      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1765        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1766    o pkg/seaice/seaice_lsr, a little bit of clean up
1767      - rearrange some code blocks, so that now all calculations for
1768        setting up the right-hand-sides done within one single block
1769        (I find that easier to read and understand)
1770      - rearrange freedrift-code to reduce the number of ifdefs
1771      - adjust some indentations and comments
1772    
1773    checkpoint64z (2014/07/10)
1774    o model/src and several pkgs:
1775      - change argument list of all S/R called from external_forcing.F and
1776        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1777        to pass, as argument, the current level tendency array to update
1778        (instead of a direct update of the common bloc array).
1779      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1780      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1781    o pkg/seaice/seaice_lsr.F
1782      - always initialize local arrays in seaice_lsr_tridiagu/v
1783      - add more local tapes to seaice_lsr_tridiagu/v
1784      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1785        keep it in bi/bj loop; this seems to be essential
1786      - gradients are still wrong but only by 4-7 orders of magnitude
1787        instead of 15 orders of magnitude, lab_sea improves a little
1788    o pkg/seaice
1789      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1790        generates unnecessary code in seaice_lsr_ad
1791      - add more store directives in seaice_lsr to avoid unnecessary code
1792        in seaice_lsr_ad
1793      - exclude some residual computations in seaice_lsr when
1794        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1795        in seaice_lsr_ad
1796      - add more storing, a new tape (model/src/the_main_loop.F) and
1797        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1798        and klockey should be checked by a specialist)
1799      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1800        and update lab_sea after previous changes in pkg/seaice below
1801    o pkg/autodiff:
1802      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1803        viscFacInAd : run time parameters allowing for adjoint switches
1804        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1805    o pkg/ecco:
1806      - introduce cost_gencost_boxmean.F that computes a box mean
1807        temperature (for use in adjoint sensitivity studies).
1808    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1809    o pkg/mom_common/mom_calc_visc.F:
1810      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1811    o pkg/seaice/seaice_summary.F:
1812      - statement for SEAICEadjMODE now in autodiff_readparms.F
1813    o pkg/seaice:
1814      - remove some store directives and add new ones in an effort to get
1815        finally rid off the recomputation warnings. This is successful
1816        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1817        defined (i.e. no extensive recomputation warnings left), but there
1818        are still too many recomputations on the solver iteration level
1819      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1820      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1821        SEAICE_SIZE.h
1822      - add a store directive in S/R seaice_calc_viscosities
1823    o pkg/seaice (ITD code):
1824      - fix definition of Hlimit for multi-threaded case
1825      - use double precision arithmetic to compute Hlimit: this affects results;
1826        update output of experiment seaice_itd.
1827    o replace content of verification/seaice_itd
1828      - instead of a 1D column use the configuration of offline_exf_seaice
1829        to test the ice thickness distribution code with ridging
1830      - this is a first shot at this experiment
1831      - change of some defaults of ridging parameters SEAICEhStar (from
1832        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1833        and lot of new comments.
1834    
1835    checkpoint64y (2014/06/20)
1836    o pkg/seaice/seaice_reg_ridge.F:
1837      - modify the regularization of very small volumes of ice; only check
1838        total volume HEFF, and do not apply correction to individual ice
1839        classes because that leads to funny patterns in the heat and fw-fluxes
1840        into the ocean. Adjust seaice_itd/results/output.txt
1841      - replace nITD by SEAICE_multDim in loop-ranges
1842    o pkg/exf:
1843      - add code to process the case field period = -12. with UV interpolation.
1844      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1845        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1846    o verification/global_with_exf:
1847      - switch all fields period to -12. (was previously untested) in input/data.exf
1848        (but keep secondary test ".yearly" unchanged); update the reference output.
1849    o pkg/cal:
1850      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1851    o pkg/exf:
1852      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1853        to replace logical switch "exf_verbose"
1854      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1855    o pkg/sbo:
1856      - update from Katherine Quinn: evaluate mass directly from density and SSH
1857        (budget using Finite Volume method) instead of from bottom pressure.
1858      - allow testreport to collect few selected SBO output ; tested in exp.
1859        global_ocean.90x40x15 (after updating the results, to include SBO output).
1860      - fix some multi-threading issues (in output part).
1861    o model/src & most packages:
1862      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1863      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1864        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1865        "data.{pkg}" exist ; and leave the S/R (return) just after.
1866      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1867        + call LAND_READPARMS from packages_readparms.F
1868    o pkg/seaice:
1869      - remove code that resets useThSice in S/R seaice_readparms and
1870        replace it by a warning in S/R seaice_check
1871      - remove parameter MULTDIM, replace with nITD and runtime
1872        parameter SEAICE_multDim (still hard-wired to nITD if
1873        SEAICE_ITD is defined)
1874    
1875    checkpoint64x (2014/05/24)
1876    o verification/lab_sea:
1877      - update adjoint and TLM output following changes to pkg/salt_plume
1878      - un-do the update after putting back local recip_Cp in few places.
1879    o pkg/salt_plume: modifications by An Nguyen:
1880      - add capability to do brine rejection (salt-plume) as function of
1881        volume+tracers (instead of only salinity tracer).
1882      - conserve volume by exchanging volume from each kLev to above to
1883        accommodate in-coming brine volume
1884      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1885      - switch KPP surf buoyancy due to brine forcing to 3-d
1886        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1887      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1888      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1889        in East/West Arctic.
1890    o pkg/sbo:
1891      - incorporate modifications from Katherine Quinn to enable the use of sbo
1892        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1893        output for future testreport verification (unfinished).
1894    o pkg/atm_phys:
1895      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1896        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1897        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1898    o pkg/seaice
1899      seaice_calc_ice_strength.F: modify expression to avoid divisions
1900        (affects truncation)
1901      seaice_do_ridging.F: clean up the insectarium
1902      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1903      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1904      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1905      - add some debugging information and error messages (warnings)
1906    o model/src: modifications relatd to atmosphere p*:
1907      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1908      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1909        of vertical profile tRef in geopotential background and anomaly.
1910      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1911        and pkg/atm_phys.
1912      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1913        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1914    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1915    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1916        not used right now, but can be used in BGC packages to fix conservation.
1917    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1918        other packages too.
1919    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1920        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1921    o model/src:
1922      - since we have several heat capacity (even in model/src), define "recip_Cp"
1923        as local variable (no longer in common block) to avoid any confusion.
1924      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1925    o pkg/exf:
1926      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1927        air density as function of air Temp, Humidity and atm pressure.
1928    
1929    checkpoint64w (2014/05/02)
1930    o verification:
1931      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1932        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1933        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1934        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1935        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1936    o model/src: for atmosphere in p* coords:
1937      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1938      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1939        but not yet activated.
1940    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1941      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1942      - this changes the results (but not for any verification experiment, because
1943        none tests this), but avoids having an extra field in the restart files
1944    o pkg/seaice: remove global variable TICE (not needed)
1945      - replace by TICES or local variable where necessary (cost_seaice_test,
1946        seaice_diagnostics_state)
1947      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1948      - use specific read/write routines for reading and writing individual leves
1949        of a multilevel field
1950    o pkg/ctrl & model/inc:
1951      - move additional anomaly fields of control vars (related to options:
1952         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1953        from DYNVARS.h into new header file: CTRL_FIELDS.h
1954    o pkg/seaice: some small modifications to the ridging code
1955      - make fw2ObyRidge a global variable and add the freshwater flux to
1956        seaice_growth
1957      - pass actual thickness from seaice_prepare_ridging, so that it is
1958        computed only in one place and compute it in the same way as in
1959        seaice_growth
1960      - initialise more fields in seaice_do_ridging that where cause floating
1961        point exceptions over land
1962    o pkg/seaice: preparations for ridging code and first real ridging code
1963      - move most of "PART 1" of S/R seaice_growth into a new and separate
1964        S/R seaice_reg_ridge that will both regularize the state variable after
1965        advection call the actual ridging routine;
1966      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1967        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1968      - remove ridging code from seaice_advdiff
1969      - clean up remaining part 1 of seaice_growth in an attempt to make it
1970        more readable (this is probably subjective)
1971      - call seaice_itd_redist once in the initialisation phase to have the initial
1972        conditions in the correct category
1973      - finally: add new ridging routine for ITD code
1974    
1975    checkpoint64v (2014/04/11)
1976    o pkg/ecco:
1977      - add runtime parameters mdt[start,end]date[1,2]
1978      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1979    o pkg/seaice:
1980      - make deltaC a global variable, so that it can be used in ridging code
1981      - first step towards ridging: introduce new routines that compute
1982        ice strength based on ridging parameters
1983      - add diagnostic for HSNOWITD
1984      - add opnWtrFrac as a global variable (required for ridging scheme)
1985    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1986      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1987        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1988    o verification/hs94.1x64x5:
1989      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1990      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1991    o autodiff:
1992      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1993        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1994        For now, only in pkgs used in verification/hs94.1x64x5.
1995      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1996        which are specific to TAF/TAMC).
1997      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1998        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1999        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
2000      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
2001        building mitgcmuv_ad (make adAll).
2002    o pkg/ecco:
2003      - cost_gencost_seaicev4.F:
2004         reformulate proxy cost as function of sst and local param SEAICE_freeze
2005         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
2006      - add stop statement if old names siv4-[sst,vol] are used
2007      - add snapshots + cost reports for atmospheric longwave
2008      - remove factor 0.1 in front of wtau[u,v]
2009      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
2010         ALLOW_TMI_SST_COST_CONTRIBUTION
2011    o pkg/atm_phys:
2012      - add some diagnostics for Short-wave and for convection S/R.
2013    o pkg/seaice/seaice_growth:
2014      - fix a bug in the lateral melt parameterization for SEAICE_ITD
2015        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
2016      - rearrange loop order for better vector code in the same code block
2017      - rewrite the floeDiameter formula to have fewer divisions
2018      -  (miraculously) none of this changes the results of seaice_itd
2019    o pkg/smooth:
2020      - move param smooth2Ddiffnbt to pkg/ecco
2021    o pkg/salt_plume:
2022      - salt_plume_frac.F:
2023         clean up local param names
2024         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
2025    o pkg/rw:
2026      - add RS version of S/R READ_MFLDS_LEV.
2027    o pkg/streamice:
2028      - fix the restart test by writing/reading pickup_streamice files.
2029    o pkg/seaice:
2030      - refine checks for jfnk-related parameters
2031      - comment out if statement with SEAICEuseIMEX parameter as long as there
2032        is no IMEX code to avoid confusion and surprises
2033    
2034    checkpoint64u (2014/03/07)
2035    o verification/MLAdjust:
2036      - rename secondary test suffix:
2037         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
2038         0.leithD -> AhFlxF  + switch to flux-form
2039         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
2040         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
2041    o pkg/mom_vecinv:
2042      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
2043        to be before mom_calc_visc.F)
2044      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
2045      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
2046        this is simpler for the adjoint and for diagnostics.
2047    o model/src + pkg/momentum:
2048      - add input files for  2-D additional Western and Southern cell-edge wall
2049         (e.g., to add "thin-wall" where it is =1).
2050      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
2051        using 2nd hFacZ that is computed from initial (fix domain) hFac
2052      - known limitations of thin wall implementation: not yet coded for sigma
2053        coords; not working with CD-scheme neither.
2054    o pkg/seaice:
2055      - rename recently introduced parameters from (wrong name) AB to
2056        BDF (backward difference time discretisation)
2057      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
2058    o tools/adjoint_options:
2059      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
2060    
2061    checkpoint64t (2014/02/01)
2062    o pkg/ecco
2063      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
2064        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
2065      - replace hard-coded record number and period which only work for monthly
2066        with read-in runtime param that works for other periods (month,day,year)
2067    o pkg/thsice
2068      - corrected store directive fixes thsice adjoint gradient checks
2069    o genmake2 & testreport:
2070      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
2071        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
2072        Update testreport accordingly. No need to set "export OPENAD=true"
2073        in adjoint_options/adjoint_oad anymore (will be removed later).
2074    o pkg/shelfice:
2075      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
2076        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
2077        so that surface forcing applies to k=kSurf if using pkg/shelfice.
2078    o pkg/ctrl, pkg/grdchk, pkg/ecco:
2079      - Changes to make GENARR more modular (i.e. invisible if not used)
2080    o model/src/temp_integrate.F and salt_integrate.F
2081      - re-include store directives that were removed on Dec 27th.
2082    o model/src/external_forcing_surf.F
2083      - add storage directives for EmPmR and PmEpR to avoid recomputation of
2084        seaice_model in the adjoint that is problematic when seaice_model is
2085        turned off in the adjoint. The resolved issue dated back to July when
2086        EXTERNAL_FORCING_SURF call was moved.
2087        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
2088    o pkg/exf/exf_check.F
2089      - fix a small bug again (originally found by Wentao Liu, now found again)
2090      - streamline error output
2091    o pkg/streamice and aim_v23:
2092      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
2093        Apple's /usr/bin/cpp knows what to do:
2094        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
2095        Target: x86_64-apple-darwin13.0.0
2096    
2097    checkpoint64s (2014/01/05)
2098    o tools/adjoint_options:
2099      - switch to fastopt.net TAF server (instead of default fastopt.de) for
2100        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
2101    o model/src:
2102      - remove some unnecessary TAF storage directives in forward_step.F and
2103        in dynamics.F (note: not always removed by TAF, e.g., double storage
2104        of kappaRU,kappaRV in former version of dynamics.F).
2105    o model/src & pkg/ptracers:
2106      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
2107        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
2108        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
2109      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
2110      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
2111      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
2112    o useSingleCpuInput separates single-CPU input from single-CPU output;
2113        for now only implemented for in exf_interp_read.F
2114    o verification/advect_xy:
2115      - fix missing EXCH call in local version of ini_salt.F and update output.
2116    o momentum diagnostics:
2117      - fix which deltaT is used in Total-Tendency diagnostics.
2118      - fix typo in diagnostics for momentum tendency from AB.
2119    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
2120        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
2121    
2122    checkpoint64r (2013/12/08)
2123    o verification/*/results:
2124      - Update reference output of experiments that were passing with just 13 digits
2125         (make it easier to detect future changes in results)
2126    o model/src & pkg/ptracers:
2127      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
2128        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
2129        to inside ptracers_integrate.F ; remove ptracers_advection.F
2130    o coupling interface pkgs:
2131        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
2132      - change the config check to test the agreement of Ocean Depth
2133        with ATM land/sea mask (instead of ATM orography);
2134      - send to coupler the number of coupler time-steps to do for this run:
2135        this allows to check for consistency and don't need anymore to be
2136        specified in parameter file "data";
2137      in coupler:
2138      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
2139      - improve report to log-file of config setting (pass log-file unit to few S/R)
2140    o pkg/compon_communic:
2141      - add coupling send/receive for non-tiled integer vector;
2142      - add S/R to check and stop if any proc has an error (similar to
2143        eesupp/src/stop_if_error.F but single thread and across Comm_World).
2144    o pkg/exch2:
2145      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
2146        through list of all tiles my proc owns.
2147    o model/src:
2148      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
2149        from rTrans) to simplify dependencies (no need to store rTrans anymore in
2150        calling S/R); this affects AD results at machine truncation level:
2151        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
2152        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
2153    o tools/build_options:
2154      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
2155    o coupling interface pkgs:
2156        [compon_communic, atm_compon_interf & ocn_compon_interf]
2157      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
2158        to each S/R that needs it; remove un-used variables.
2159      - change component tile registration (cpl_register.F in both compon_interf
2160        and mitcomponent_tile_register.F) to pass the full list of tiles
2161        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
2162      - with pkg/exch2: adopt the same convention used for I/O to define mapping
2163        towards coupler global array (unless W2_useE2ioLayOut=F):
2164         a) can now use different tiling between atm & ocn comp.
2165         b) no needs to modify the run-Off map when changing tiling (was needed
2166            even if using the same tiling between atm & ocn).
2167         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
2168            full land tiles); not yet tested.
2169      - check for valid mapping from comp. tile to coupler global array
2170      - improve report of tile registration results to log file.
2171    o pkg/exch2:
2172      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
2173        tile-registration (CPL_REGISTER);
2174      - activate (un-comment) definition and setting of "W2_tileIndex" list to
2175        store the local bi,bj indices of each tile;
2176      - also print bi,bj in local report to log file;
2177      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
2178        Jun 2009 modif of pkg/exch2).
2179    o testing on baudelaire:
2180      - run 2 tests at a time: no significant slow down (since enough cpu) and
2181        get the full set of test done earlier
2182      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
2183    o model/src/thermodynamics.F and routines called from it:
2184      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
2185        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
2186        velocity (outp) by adding bolus velocity.
2187      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
2188        mass transport from velocity + lateral grid cell area
2189      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
2190      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
2191     in thermodynamics.F
2192      - remove k from thermodynamics.F and move it to temp_integrate.F
2193        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
2194        loop).
2195      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
2196        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
2197        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
2198        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
2199      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
2200        global_ocean.90x40x15, tutorial_global_oce_biogeo and
2201        tutorial_tracer_adjsens (+ TLM output).
2202    o tools/OAD_support and (verification/*/) code_oad:
2203      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
2204        module conversion ; remove unneeded CPP_EEOPTIONS.h.
2205      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
2206        version (closer to model/inc/CPP_OPTIONS.h).
2207    o model/src:
2208      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
2209        retired list of parameters (routine FREEZE has been replace by surface
2210        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
2211    o pkg/gmredi:
2212      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
2213        velocity (same scheme but affects machine truncation) for GM_AdvForm.
2214      - update output of FWD experiments: front_relax.bvp,
2215        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
2216    
2217    checkpoint64q (2013/11/17)
2218    o verification:
2219      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
2220        tutorial_global_oce_biogeo and global_ocean.90x40x15.
2221      - generate new output (growth & melt) for seaice_itd experiment after
2222        updating the input pickup_seaice files (previously wrong).
2223    o pkg/cost:
2224      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
2225        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
2226        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
2227          cannot be applied to var in common block).
2228        o allows to get results independent of tile-per-proc setting (if using
2229          slower GLOBAL_SUM_SEND_RECV option).
2230      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
2231        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
2232        forward gradients: update output).
2233      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
2234        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
2235    o pkg/mom_common:
2236      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
2237        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
2238        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
2239        ensure that all field value that are used are set.
2240    o tutorial_deep_convection (smag3d):
2241      - add missing scaling in mom_calc_smag_3d.F;
2242      - set smag3D_coeff in input.smag3d such that results do not change.
2243    o pkg/dic:
2244      - change dic_cost.F to compute cost on each tile first and then apply
2245        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
2246        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
2247      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
2248    o eesupp/src & pkg/mdsio:
2249      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
2250        (from pkg/mdsio) since they are no longer used for tape IO.
2251      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
2252        (+ keep a copy in pkg/atm_ocn_coupler).
2253    o verification/isomip:
2254      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
2255    o tools/build_options:
2256      - optfile linux_amd64_ifort11, fast (no ieee) case:
2257        to get a working restart for all experiments, add "-fp-model source"
2258        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
2259    
2260    checkpoint64p (2013/10/20)
2261    o pkg/autodiff:
2262      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
2263        criteria, return to simple (default) tape IO format.
2264    o pkg/mdsio (+ eesupp/src):
2265      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
2266        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
2267      - fix globalFile and singleCpuIO options using simpler global mapping.
2268      - new pairs of scatter/gather vector S/R (one for each type, generated from
2269        template) corresponding to simpler global mapping.
2270      - adread_write.F: switch to new S/R (but leave old calls commented) and write
2271        to globalFile when parameter globalFiles is set to True.
2272      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
2273    o pkg/autodiff:
2274      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
2275        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
2276        missing, just add a STOP if array type do not match.
2277    o pkg/exf:
2278      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
2279         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
2280         and rename array obsSIce to exf_iceFraction.
2281    o tutorial_deep_convection:
2282      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
2283        for now all in this exp. code dir.
2284      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
2285        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
2286    o eesupp/src:
2287      - added SINGLE_DISK_IO option because reading of parameter files on
2288        very large number of processors did not work with existing set-up
2289    
2290    checkpoint64o (2013/09/25)
2291    o pkg/atm_phys & atm_compon_interf:
2292      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
2293    o tools/build_options:
2294      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
2295        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
2296        remove CPP setting (was identical to genmake2 default).
2297    o pkg/gmredi & model/src: Some updating and work done on the residual model.
2298      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
2299      - fixed up the calculation of the eddy stress and how it is added to the
2300        external forcing via taueddy_external_forcing.F
2301      - at the moment, it is very experimental and only works with the variable eddy
2302        diffusivity calculated in gmredi_k3d.F
2303    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
2304        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
2305    o testreport (& tools/do_tst_2+2):
2306      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
2307    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
2308      - remove CPP='cpp -traditional -P' (this is genmake2 default)
2309      - add switch (for big setups) to use 'medium' memory-model (but leave it
2310        commented out for now). Note: needed with FC 19 to compile big setups.
2311    o pkg/atm_compon_interf:
2312      - regroup per field origin (model & pkgs) the coupling storage routines
2313         (which accumalate in time each coupling field)
2314      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
2315        update accordingly + simplify aim_do_physics.F
2316    
2317    checkpoint64n (2013/08/26)
2318    o pkg/bbl:
2319      - update formulation to reduce dispersion of tracer properties in bbl
2320      - replaced horizontal and vertical transport parameters with velocities
2321      - changes results for verification/global_with_exf.yearly
2322    o verification/halfpipe_streamice:
2323      - change to matrix construction; update both Fwd & AD output.
2324    o verification/tutorial_tracer_adjsens:
2325      - OpenAD test: switch to vector-invariant momentum since fluxform with
2326        rStar causes problems with OpenAD; update output.
2327    o tools:
2328      - genmake2: define a common prefix for all temp-file names ; move them
2329        to local /tmp disk (but would be easy to move them back);
2330      - xmakedepend: apply the same switch for temp-files.
2331    o pkg/offline:
2332      - changes for use with rStar (NLFS): assume that we continue to provide
2333        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
2334        output files) and apply r* scaling at each time-step (function of the time
2335        varying Eta field); use normal pickup files (needed for restart with NLFS).
2336    o adjoint with OpenAD:
2337      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
2338        package openad.  This package has to be compiled for all runs with OpenAD
2339        instead of specifying code_oad_all as a modification directory.
2340      - link the fortran templates from tools/OAD_support to the build directory
2341        for preprocessing to avoid conflicts between different setups compiled
2342        simultaneously and simplify cleanup.
2343    o pkg/exf:
2344      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
2345        main model or other pkgs are exchanged in EXF_MAPFIELDS).
2346    o model/src:
2347      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
2348        (similar to do_fields_blocking_exchanges.F).
2349    o tools/genmake2:
2350      - remove TAF output src code just before calling staf (when not doing a fresh
2351        built, will stop if things go wrong with staf).
2352      - fix target "adobj" (left from TAF version-2 transition)
2353    o pkg/diagnostics:
2354      - add a parameter to track the status of pkg/diagnostics activation;
2355        this replace/extend the use of logical param "settingDiags" (to check
2356        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
2357        New S/R to print error message and stop when pkgStatus is not right.
2358      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
2359    
2360    checkpoint64m (2013/08/13)
2361    o model/inc:
2362      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
2363        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
2364    o pkg/kpp & aim_v23:
2365      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2366    o pkg/seaice:
2367      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
2368        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
2369      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2370    o eesupp/src:
2371      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
2372        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
2373    o switch to TAF version-2:
2374      - add flow directives to "freeze" naming convention for ad-routines that
2375        are used in I/O routines of adjoint state and associated common blocks
2376        that are used in adcommon.h (backward compatible with version-1)
2377      - update all ad-optfiles (in tools/adjoint_options + few local to some
2378        verification exp) to switch to latest TAF version (currently 2.5.5);
2379        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
2380        out except for diva).
2381      - the major change with TAF version-2 is that both the differentiated
2382        routines and the forward routines (new) are returned as part of the TAF
2383        output source code. Update genmake2 accordingly.
2384      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
2385        with version-2 when compared to TLM or FWD gradient); other experiments
2386        output show minor changes (machine truncation level); update the few AD &
2387        TLM output with 12 matching digits only (some prior to version-2 switch).
2388    
2389    checkpoint64l (2013/08/05)
2390    o model/src:
2391      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
2392      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
2393        when using TAF but only if using OpenAD.
2394    o pkg/mom_common+fluxform+vecinv:
2395      - always set horiz. viscosity arrays to background value before calling
2396        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
2397        only when using variable horiz. viscosity (useVariableVisc=T);
2398      - simplify mom_vecinv.F (only 1 block for momViscosity).
2399    o pkg/mom_common: variable horiz. viscosity in NH code
2400      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
2401        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
2402      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
2403        useBiharmonicVisc & useVariableVisc.
2404      - fix old bug (already in 1rst implementation of variable horizontal viscosity
2405        in calc_gw.F, version 1.27, 2006/06/20):
2406        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
2407        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
2408      - change background horiz viscosity in vertical momentum (gW) to always be
2409        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
2410        any type of variable viscosity, e.g., viscAh/4Grid)
2411      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
2412        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
2413        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
2414        default viscAh,viscA4 is zero).
2415    o model/src:
2416      - extend length of drC & recip_drC from Nr to Nr+1.
2417    o Divided Adjoint (DIVA) with MPI:
2418      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
2419      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
2420        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
2421    
2422    checkpoint64k (2013/07/23)
2423    o tools/OAD_support:
2424      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
2425        and remove it from genmake2.
2426    o tools/build_options:
2427      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
2428        MPI_HEADER_FILES list (let genmake2 find the missing headers)
2429    o verification/halfpipe_streamice:
2430      - change to driving stress formulation; update both Fwd & AD output.
2431    o tools/genmake2 and Divided Adjoint with MPI:
2432      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
2433      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
2434      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
2435        Makefile, which is set by genmake2, and check which mpi-headers are needed.
2436        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
2437      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
2438    o testreport:
2439      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
2440        perform additional runs (number of additional runs is "add_DIVA_runs" taken
2441        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
2442    o verification/lab_sea (AD test):
2443      - change to test Divided Adjoint Run in this set-up (both standard AD test
2444        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
2445    o pkg atm_ & ocn_compon_interf:
2446      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
2447        staggerTimeStep implementation) and disable (retired) corresponding
2448        parameter.
2449    o pkg/offline:
2450      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
2451      - add S/R OFFLINE_CHECK to print offline parameter summary
2452        and stop if loading a file that is not used;
2453      - enable to calculate GMRedi tensor, KPP mixing and convective index
2454        when the corresponding file(s) is/are not specified (but pkg is used).
2455      - comment out resetting of monitorFreq (to endTime) since it still useful
2456        for monitoring CFL numbers and checking offline fields.
2457    o OpenAD:
2458      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
2459        smaller standard output) and generate new (smaller) output (on baudelaire
2460        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
2461    o model/src:
2462      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
2463        (where external_forcing_adjust was called) and change list of arguments;
2464      - merge external_forcing_adjust.F into external_forcing_surf.F
2465      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
2466        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
2467        previously in file "balance_relax.F", now removed); remove corresponding
2468        arrays in FFIELDS.h.
2469      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
2470        a hack for getting back surfaceForcingS (loaded from file) when using
2471        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
2472      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
2473        (was getting only 11 digits for AD-grad, due to different truncation
2474         error in AD code).
2475    
2476    checkpoint64j (2013/07/04)
2477    o pkg/offline:
2478      - to enable the use of other features with pkg offline (e.g., obcs),
2479        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
2480      - comment out "allowFreezing" (now active) in 2 offline testing exp.
2481  o pkg/exf ALLOW_RUNOFTEMP  o pkg/exf ALLOW_RUNOFTEMP
2482    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL    - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
2483    - added RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice    - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
2484    - changes verification/global_ocean.cs32x15/results/output.seaice.txt    - changes verification/global_ocean.cs32x15/results/output.seaice.txt
2485  o pkg/atm_phys:  o pkg/atm_phys:
2486    - allows to add some damping on uVel,vVel (strength only function of k).    - allows to add some damping on uVel,vVel (strength only function of k).
