5      ==============================      ==============================
6    
7    checkpoint66k (2017/09/20)
8    o model/src:
9      - add missing CPP brackets (ALLOW_COST, ALLOW_CTRL in load_fields_driver.F
10        and the_model_main.F)
11    o ctrl:
12      - use zeroRL in place of fc when ALLOW_COST is not compiled (in ctrl_pack.F)
13      - call MDS_READ_FIELD / MDS_WRITE_FIELD instead of deprecated
14        mdsreadfield / mdswritefield (in ctrl_get_gen.F, ctrl_map_ini_gen.F,
15        ctrl_map_ini_genarr.F, and ctrl_map_ini_gentim2d.F )
16    o eesupp:
17      - add CPP option to activate some pieces of code for coupling to GEOS AGCM;
18      - shift commonly used IO unit (in eeboot.F) for coupling to GEOS AGCM.
19    o pkg/bling:
20      - bling_production: Fix typo in calcium carbonate uptake. Also rearranging
21        and cleaning
22    o model/src:
23      - move k loop inside correction_step.F (+ update calling S/R)
24      - collect implicit pressure gradient tendencies in local 2-D array;
25        affect results (at machine truncation level) when using 3-D solver; update
26        output of exp.: exp4 (x1), global_ocean.cs32x15 (x2),hs94.cs-32x32x5.impIGW,
27                        rotating_tank, short_surf_wave,tutorial_deep_convection (x2)
28                        & tutorial_plume_on_slope.
29    
30    checkpoint66j (2017/08/15)
31    o pkg/ptracers:
32      - fix surface forcing under ice-shelf (useShelfIce=T).
33    o pkg/atm_phys:
34      - use hFac weighted average when applying A-grid atm-phys momentum tendency
35        to C-grid dynamics; this ensures wind-stress match mom tendency.
36    o eesupp/src:
37      - change default for opening scratch files to avoid STATUS='SCRATCH'
38      - close scratch files with STATUS='DELETE'
39      - changes affect eeset_parms.F and open_copy_data_file.F and many routines
40        that read namelists (because they close the scratch files)
41      - you can revert to old default by setting USE_FORTRAN_SCRATCH_FILES
42        in CPP_EEOPTIONS.h (tested in ideal_2D_oce/code & lab_sea/code_ad)
43    o pkg/atm_phys:
44      - fix unset arguments in (unused) S/R surface_flux_0d.
45    o eesupp/src:
46      - add argument "procId" to S/R EESET_PARMS to fix  scratchFile1 & 2 setting
47        (case TARGET_BGL or TARGET_CRAYXT) for early call (from eeboot_minimal.F):
48        called with myProcId in eeboot.F and with mpiMyWId in eeboot_minimal.F
49    o pkg/streamice:
50      - remove blank between _EXCH_XY_RL and "()", which my Apple Xcode
51        preprocessor /usr/bin/cpp cannot interpret; 3 instances in total in
52        streamice_driving_stress_fd.F and streamice_advect_2dtracer.F
53    o pkg/diagnostics:
54      - new option to allow to cumulate thickness-factor (hFac) weighted field
55        (if field permitted); implemented by changing sign of "jdiag" pointer
56        (> 0: cumlulate field, < 0: cumulate hFac weighted field).
57        a) restricted to 3-d (Nr levels), level centered diagnostics at U,V or Cell
58           center position (gcode(2)='U','V','M' & gcode(3,5,9:10)='R',' ','MR')
59        b) for now, activated by setting fileFlags 3rd character to 'h'.
60    
61    checkpoint66i (2017/07/18)
62    o pkg/cheapaml:
63      - add parameter "useRelativeWind", default set to False; this change the
64        previous setting which was always using relative wind.
65    o add hooks for the Parallel Data Assimilation Framework PDAF
66        (http://pdaf.awi.de/) in eeboot_minimal.F and the_main_loop.F;
67        to use set CPP-flag USE_PDAF in CPP_EEOPTIONS.h
68    o pkg/exf:
69      - interpolation of vector fields (exf_interp_uv.F): fix bug in calculation
70        of South-Pole mean value.  
71      - interpolation near the poles, case where second additional row is at the
72        pole (or beyond the pole and moved to the pole): change first addition row
73        value to a linear interpolation between pole and 1rst (S.pole)/last (N.pole)
74        row (instead of just a copy of it).
75    o pkg/seaice:
76      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
77      - add the option to compute no-slip du/dy, dv/dx (i.e.
78        the offdiagonal strain rate e12) by a second order approximation
79        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
80        it is too messy to implement for the implicit LSR matrix.
81        SEAICE_2ndOrderBC = .FALSE. by default
82    
83    checkpoint66h (2017/06/02)
84    o pkg/seaice:
85      - add new routines to compute stress tensor components and stress tensor
86        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
87      - change names of diagnostics SIsigI/II (commonly used for invariants)
88        to SIsig1/sig2 (more common for principal components) to avoid confusion
89    o pkf/exf:
90      - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
91        similarly, stop if rotateStressOnAgrid with constant wind-stress.
92    o pkg/seaice:
93      - remove (comment out) diagnostics SIuwind,SIvwind,SIfu,SIfv (duplicate of
94        EXFuwind,EXFvwind,oceTAUX,oceTAUY) and point them to their equivalent.
95      - add diagnostics of wind-stress over seaice (SItaux,SItauy) and seaice
96        fraction weighted wind stress over ocean+seaice (SIatmTx,SIatmTy).
97    o pkg/diagnostics:
98      - small piece of code to rename (old) diagnostics, when namelist is processed.
99    o model/src:
100      - new run-time param (useMin4hFacEdges) to select method for setting hFacW,S:
101        originally, set as minimum of adjacent hFacC factor ; now (new default)
102        computed from rSurfW,S and rLowW,S by applying same rules as for hFacC.
103        Only matters when useShelfIce=T with particular ice-shelf cavity geometry.
104    o pkg/seaice:
105      - add momemtum advection, off by default, still in test phase
106        most of the momentum advection code is adapted and reused from mom_vecinv
107    o pkg/mom_vecinv:
108      - pass these runtime flags:
109        selectVortScheme, highOrderVorticity, upwindVorticity, useJamartMomAdv
110        as formal parameters to s/r mom_vi_u/v_coriolis, mom_vi_u/v_coriolis_c4,
111        so that these routines can also be used in pkg/seaice.
112    
113    checkpoint66g (2017/04/24)
114    o model/src:
115      - more robust ordering of column thickness integral (=Sum_k(drF*hFac) )
116        to get same expression (regarding machine truncation) in different places
117        in ini_masks_etc.F (e.g., rSurfC,W,S is now exactly zero when it should).
118        Update forward output of experiments: global_ocean.cs32x15 (all 5 except
119        viscA4), isomip (x3), tutorial_global_oce_in_p & tutorial_plume_on_slope.
120    o pkg/shelfice:
121      - ALLOW_SHIFWFLX_CONTROL: move setting of maskSHI from shelfice_update_masks.F
122        to shelfice_init_fixed.F
123      - change S/R SHELFICE_UPDATE_MASKS to SHELFICE_INIT_DEPTHS (still called from
124        ini_masks_etc.F for now) to update ocean upper boundary position according
125        to ice-shelf topography (instead of directly updating hFacC).
126    o model/src:
127      - move call to CTRL_INIT & CTRL_ADMTLM from the middle to the bottom of
128        packages_init_fixed.F to allow other pkgs to set mask and weight fields.
129    
130    checkpoint66f (2017/04/06)
131    o model/src:
132      - add specific run-time param to select level of printed plot-field-maps,
133        set by default to debugLevel. Remove internal param "printDomain".
134    o pkg/seaice:
135      - add flag to add snow mass to seaiceMassC/U/V, the default is
136        SEAICEaddSnowMass=.FALSE., not to change previous results
137    o pkg/bling
138      - Bug fix in bling_production regarding unit conversion for diagnostics
139        being put in the wrong place
140    o model/src:
141      - add back recomputation of rSurfW & S to ensure consistent column thickness
142        (needed for rStar) between Sum_k(hFac*drF) and rSurf-rLow, for now only
143        when using pkg/shelfice; was initially added on 2012/06/01 (ini_masks_etc.F
144        revision 1.51) but was removed accidentally on 2014/02/08 (v1.53).
145    o pkg/autodiff:
146      - clean-up "checkpoint.flow"
147    o pkg/rw (Contribution from Jody Klymak):
148        option to set mds file suffix as function of time in simulation:
149        *) new input parameter "rwSuffixType" (read from PARM03 namelist)
150           to select file suffix format; by default (=0), use iteration number;
151        *) add simple routine to return file suffix according to rwSuffixType;
152        *) in model/src and in most pkgs (except: atm2d, fizhi, regrid & streamice),
153           use new S/R to get file suffix, except for debug output file (diagFreq)
154           and pkgs offline & rbcs input files.
155    o pkg/rw:
156      - uniform processing of "I10" suffix across writing fld routines; used to
157        simplify debug writing of cg2/3d_b/x in solve_for_pressure.F & post_cg3d.F
158        (similar to cg3d.F, cg3d_ex0.F)
159    o pkg/mom_vecinv:
160      - highOrderVorticity in selectVortScheme=2 case: fix c4 coeff in splitted
161        vorticity flux (keep same sum in case vBarXm=vBaXp, uBarYm=uBarYp).
162    o pkg/bling:
163      - Many small changes intended to clean the code.
164        Unnecessary ADJOINT_SAFEs removed ;
165        removed BLING_COST.h BLING_CTRL.h bling_cost.F ;
166        diagnostics added.
167    
168    checkpoint66e (2017/03/14)
169    o pkg/exf:
170      - interpolation with #undef EXF_INTERP_USE_DYNALLOC: move buffer size
171        definition outside EXF_PARAM.h in new header file: EXF_INTERP_SIZE.h;
172        use fixed size buffer (passed to S/R EXF_INTERP & EXF_INTERP_UV) to
173        avoid any dynamic allocation ;
174      - S/R EXF_CHECK: add new check & stop when file-name is defined but not
175        read-in ; add warning when file is read-in but not used within pkg/exf ;
176        + check for buffer-size (if #undef EXF_INTERP_USE_DYNALLOC).
177      - update exf_summary.F (print {FLD}RepCycle).
178    o verification/global_with_exf:
179      - switch on exf interpolation in AD test (just like the forward test)
180    o pkg/mom_vecinv:
181      - add storage directives to avoid recomputations within mom_vecinv.F
182        which were generating seg. fault with gfortran -devel
183    o pkg/ctrl, pkg/smooth:
184      - initialize array halos which were generating seg. fault with
185        gfortran -devel in adjoint mode
186    o pkg/exf:
187      - for each input field, enable to specify a field specific repeat-cycle
188        ({FLD}RepCycle) which defaults to pkg/exf main "repeatPeriod".
189    o verification/lab_sea:
190      - update AD results of primary test and noseaicedyn test after switching
191        to new version of TAF (5.3.13 vs 5.3.2 before); agreement with gradient
192        check stays about the same.
193    o pkg/exf:
194      - fix bug in exf_zenithangle.F for cases select_ZenAlbedo > 0 with useCAL=T.
195      - exf_check: MAX_LAT_INC need only be "loc_nlat-1", not equal to loc_nlat
196    o pkg/bling, USE_EXFCO2 code:
197      - add parameter "apco2RepCycle" (set to pkg/exf "repeatPeriod" by default);
198      - update calls to EXF S/R (use new version: EXF_INIT_FLD & EXF_SET_FLD).
199    o pkg/exf:
200      - rename S/R EXF_INIT to EXF_INIT_VARIA ;
201      - add arguments: fldName (for debug msg) and fldRepeatCycle (set to
202        repeatPeriod) to S/R EXF_SET_UV and to S/R EXF_SET_GEN (renamed EXF_SET_FLD)
203        and update calls in pkg/exf calling S/R (exf_getffields.F & exf_getclim.F) ;
204      - add argument: fldName (for debug msg) to S/R EXF_INIT_GEN (renamed
205        EXF_INIT_FLD) and update calls in exf_init_varia.F
206      - For now, for backward compatibility, keep a simplified version of S/Rs
207        EXF_SET_GEN & EXF_INIT_GEN in file exf_set_gen.F
208      - add and pass new arguments: fldName (for debug msg) and fldRepeatCycle
209        to S/R EXF_GetFFieldRec ; update calls in pkg/obcs/obcs_exf_load.F
210    o tools/genmake2:
211      - replace "bc -l" (only used once) by "expr" (already used).
212    o verification/global_ocean.cs32x15:
213      - turn off pkg/cal (useCAL=F) in secondary FWD exp. "icedyn".
214        Note: exf setting (data.exf) can be compared to other exf secondary exp
215        "seaice" (kept with useCAL=T) which has same time dependent forcing.
216    
217    checkpoint66d (2017/02/13)
218    o pkg/exf:
219      - remove setting of useCAL=T when using pkg/exf (useEXF=T); add warning
220        early on (in packages_boot.F) to stress this change in pkg setting.
221      - In (most) verification exp. that use pkg/exf, add useCAL=.TRUE. to data.pkg
222    o model/src:
223      - move call to ecco_phys to end of time step; this may induce minor
224        cost function changes by shifting time averages by one time step
225        for some variables; this revision resulted in changed adjoint results
226        in MITgcm_contrib/verification_other/global_oce_cs32
227    o pkg/exf:
228      - Change EXF_READ_EVAP to only activate code within #ifdef ALLOW_ATM_TEMP ;
229        this prevents to read evap when ALLOW_ATM_TEMP is undef and other fields,
230        e.g. precip, are not available.
231    o pkg/flt:
232      - flt_init_varia.F: use pickupSuff if specified
233      - add code (within #ifdef DEVEL_FLT_EXCH2) and test case as a first,
234        intermediate, step towards completing pkg/exch2 support within pkg/flt;
235        ifdef DEVEL_FLT_EXCH2 then:
236        - flt_init_fixed.F: comment out stop
237        - flt_exch2.F: conserve ipart, jpart (grid coordinates)
238        - exch2_recv_get_vec.F: transform ipart, jpart (grid coordinates)
239        - flt_mapping.F: attempt to fix longitude diagnostic near date-line
240        - flt_init_varia.F: hack initialization (for testing purposes w. LLC90)
241    o tools/genmake2 & pkg/pkg_depend:
242      - define new type of pkg dependency rule ("=pkg_x"), less strict than
243        the "+" rule, that add the dependent pkg (pkg_x) unless it's disabled
244        (-pkg_x in packages.conf).
245      - change pkg/exf dependency rule from "exf +cal" to "exf =cal";
246      - add "+cal" to dependency list of pkg/ecco (needed to compile).
247      - simplify FWD experiment "offline_exf_seaice" by removing pkg/cal.
248    o utils/matlab:
249      - adding ocean_basin routines for defining basin masks.
250    o pkg/exf:
251      - new S/R EXF_GETFFIELD_START replacing EXF_GETFIELD_START, but with more
252        arguments, allowing to check (and stop) if parameter setting of
253         {FLD}startdate1 & date2 and of {FLD}StartTime are consistent with
254        useCAL= T or F. For now, kept a simplified version of EXF_GETFIELD_START
255        for backward compatibility.
256      - change accordingly calls in exf_init_fixed.F + default {FLD}StartTime in
257        exf_readparms.F ; apply same changes to pkg/icefront (for SGRunOff field).
258    o pkg/bling (USE_EXFCO2 code):
259      - fix missing setting of apco2StartTime according to apco2startdate1 & date2
260        by adding a call to S/R EXF_GETFFIELD_START.
261    o pkg/exf:
262      - allows to compile without pkg/cal (but disabled by current dependency
263        rules, i.e., default "pkg/pkg_depend"). Minimal changes to enable to
264        run with useCAL=F ; this involves setting directly {FLD}StartTime instead
265        of {FLD}startdate1 & date2 ; consistency check not yet coded.
266    o verification/global_ocean.cs32x15:
267      - fix all data.exf for a shift of 1 day in all field startdate1 so that it now
268        corresponds to middle of 1rst month; update outputs (2 fwd + 3 adm + 3 tlm).
269    o pkg/exf:
270      - allow to use EXF_ZENITHANGLE without pkg/cal + simplify (saving some
271        calculations); change FWD experiment global_ocean.cs32x15
272        (#define ALLOW_ZENITHANGLE) to test/check that this code compiles.
273    o pkg/exf:
274      - In preparation for addition to NAMELIST, rename internal (_RL) parameter
275         {FIELD}startdate to {FIELD}StartTime
276        Note: new name also fit better the content, i.e, a start time in second.
277    o eesupp/src:
278      - add 1 argument to S/R EEBOOT & EEBOOT_MINIMAL for interface with ESMF
279    o pkg/exf:
280      - add option ALLOW_READ_TURBFLUXES (and corresponding set of parameters)
281        to allow to read-in Sensible & Latent Heat flux ;
282      - simplify pkg/exf main options:
283        1) move small piece of code (case ALLOW_ATM_TEMP undef) out of
284           exf_bulkformulae.F into exf_wind.F so that exf_bulkformulae.F is
285           compiled only when both ALLOW_ATM_TEMP & ALLOW_BULKFORMULAE are defined;
286        2) make call to EXF_RADIATION and to EXF_WIND independent of CPP option
287           ALLOW_BULKFORMULAE which now only applies to S/R EXF_BULKFORMULAE ;
288        3) improve options documentation in EXF_OPTIONS.h.
289    o pkg/ecco:
290      - cost_gencost_customize.F,ecco.h,ecco_phys.F,ecco_readparms.F, and
291        ecco_summary.F: add passive tracer cost functions to gencost;
292        m_ptracer and m_boxmean_ptracer
293    o pkg/ctrl:
294      - ctrl_map_forcing.F: pass myIter and myTime to ctrl_map_forcing as input
295        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing; add to list
296        of implemented gentim2d contol parameters: xx_qnet, xx_empmr, xx_qsw,
297        xx_sst, xx_sss, xx_pload, xx_saltflux, xx_fu, xx_fv, xx_fe, xx_fn
298    o model/src:
299      - forward_step.F: pass myIter and myTime to ctrl_map_forcing as input
300        parameters; move myIter .EQ. nIter0 inside ctrl_map_forcing
301    o pkg/exf:
302      - exf_getffields.F: add to list of implemented gentim2d contol parameters:
303        xx_lwflux, xx_swflux, xx_evap, xx_apressure, xx_areamask
304    
305    checkpoint66c (2017/01/19)
306    o verification:
307      - add new option "-src" to testreport to only produce source code (*.f),
308        including taf output src code (if using '-adm'/'-tlm' option).
309    o pkg/exf:
310      - add saltflx :: Net upward salt flux in psu.kg/m^2/s
311    o pkg/diagnostics:
312      - add run-time variable diagMdsDir to specify a subdirectory for
313        diagnostic output when mds is being used and mdsioLocalDir is not.
314    o pkg/mnc:
315      - mnc_utils.F: edit stop message
316    o pkg/autodiff:
317      - autodiff_ini_model_io.F: PRINT_MESSAGE, clean-up comments, add _*_MASTER,
318        add HAVE_SYSTEM bracket around system call to mkdir
319    o pkg/profiles:
320      - profiles_findunit.F, profiles_init_fixed.F, profiles_interp.F,
321        profiles_readparms.F: call ALL_PROC_DIE before 'stop'
322      - profiles_ini_io.F: use PRINT_MESSAGE, clean-up comments, add _*_MASTER,
323        add HAVE_SYSTEM bracket around system call to mkdir
324    o pkg/smooth:
325      - smooth_filtervar2d.F, smooth_filtervar3d.F: call ALL_PROC_DIE before 'stop'
326      - smooth_init2d.F, smooth_init3d.F: move print statements to readparms
327      - smooth_readparms.F: add cleaner print statements from smooth_init?d.F
328    o pkg/exf:
329      - check: count errors and stop cleanly at the end (call to ALL_PROC_DIE);
330        issue error message when climsst_interpMethod.GT.0 and climsst_lon_inc > 500
331        generalize tests on interpMethod, nlat, and lon_inc to all exf variables.
332      - summary: skip detailed field report if not used (empty file-name).
333    o tools/xmakedepend:
334      - In case line editor "ed" is missing, switch to "sed" command to clean-up
335        Makefile from previous dependencies (anything after "# DO NOT DELETE" line).
336    o pkg/exf:
337      - change definition of "hflux" input file to always include Short-Wave;
338        this is now consistent with hflux computation (if using bulk-formulae)
339        and hflux diagnostic & documentation (in EXF_FIELDS.h).
340    
341    checkpoint66b (2016/12/01)
342    o model & momentum pkgs:
343      - implement fully implicit bottom friction combined with implicit surf.
344        pressure, for now, only in hydrostic formulation:
345        + to use: compile with #define ALLOW_SOLVE4_PS_AND_DRAG in CPP_OPTIONS.h
346          and run with selectImplicitDrag=2 ;
347        + currently missing diagnostics of bottom drag and vert. viscosity tendency;
348      - partial implicit time-stepping (bot. friction + vert. visc first, then
349        surf. press) corresponding to selectImplicitDrag=1 should be applicable
350        to NH formulation but not available until we solve for surf. pressure
351        increment (instead of full etaN).
352      - change exp. global_ocean.cs32x15.thsice to test implicit bottom drag
353        with implicit vertical viscosity.
354    o pkg/seaice: add linear remapping scheme (Lipscomb 2001) to ITD model
355      - this is a first version that includes many regularisations that may
356        not all be necessary, to be sorted out,
357      - turned on by runtime parameter SEAICEuseLinRemapITD (true by default)
358      - change one verification experiment in seaice_itd to use and test new code
359      - seaice_growth: catch a case where the argument of log can be zero
360        or smaller (important for code stability)
361    o model/src:
362      - modify SOLVE_DIAGONAL_LOWMEMORY version of solve_tridiagonal.F
363        & solve_pentadiagonal.F to enable to re-used inverse matrix for solving
364        similar A.X'=Y' system (with same matrix A) in subsequent calls;
365        switch based on errCode (In/Out) argument value; in calling routines,
366        initialise errCode before first call.
367    
368    checkpoint66a (2016/10/18)
369    o pkg/bling:
370      - BLING package now loads in atmospheric pCO2 file using exf package routines
371        Enable with #define USE_EXFCO2 in BLING_OPTIONS.h
372    o model/src & pkg/ptracers:
373      - with INCLUDE_IMPLVERTADV_CODE defined, also call MOM_U,V_IMPLICIT_R &
374        GAD_IMPLICIT_R (instead of IMPLDIFF) when just implicitViscosity and
375        implicitDiffusion (respectively) are used (even without momImplVertAdv
376        or temp,salt,PTRACERS_ImplVertAdv).
377    o model/src & generic_advdiff:
378      - add parenthesis in main diagonal calculation of implicit vertical
379        diffusion matrix (impldiff.F & gad_implicit_r.F).
380        This affects results at machine truncation level; update output of many
381        verification experiments (31 fwd ; 10 adm ; 8 tlm ; 3 oad).
382    o pkg/mom_commom & generic_advdiff:
383      - add deep atmosphere and anelastic scaling factor in implicit vertical
384        advection routines (mom_u,v_implicit_r.F & gad*_impl*_r.F).
385    o model/src:
386      - remove few unnecessary temp array copies in solve_tridiagonal.F
387        & solve_pentadiagonal.F
388    
389    checkpoint65z (2016/09/28)
390    o pkg/seaice: fix multithreading for seaice_fgmres.F
391      - remove unecessary variables from common blocks
392      - use extra dimension MAX_NO_THREADS for all variables of the Krylov space
393        basis, that are stored in commom blocks (including integer variable i1)
394      - clean up code a little by removing commented lines that refer to
395        original code
396      - turn on multi-threaded test for experiment offline_exf_seaice.dyn_jfnk.
397    o MITgcm manual:
398      - add uptodate pkg/ecco documentation to the manual (section 8.1; ecco.tex),
399        preliminary documentation for generic controls (8.3; ctrl.tex),
400        a placeholder for smooth (8.4; smooth.tex), and comment out the deprecated
401        ecco_costfunction.tex
402    o pkg/ecco:
403      - update and cleanup list of CCP options
404      - re-assign gencost_mask to specify masks rather than gencost_errfile; 'c'
405        is now always passed to cost_generic; gencost_mask is now MAX_LEN_FNAM
406      - add checks that retired run-time options are not used, and in relation
407        to gencost_mask and gencost_errfile
408      - finish deprecating gencost_scalefile, gencost_smooth2Ddiffnbt, and
409        gencost_nrecperiod
410      - fix m_eta computation for virtual salt flux case
411      - add m_horflux_vol case (selected via gencost_barfile) that computes
412        transports via cost_gencost_boxmean (gencost_flag=-3)
413      - use gencost_flag more systematically (i.e., avoid using gencost_name)
414        for code switches (aside from physical variable selection)
415    o pkg/seaice: make seaice_fgmres.F fit for multithreading; this first
416      attempt appears to be a bit of a hack and my need some repair down the road
417    o pkg/exf:
418      - interpolation near South Pole: fix criteria on input field latitude.
419    o pkg/icefront & pkg/exf:
420      - move setting of icefront Sub-Glacial RunOff forcing (currently unused)
421        from pkg/exf (read from data.exf) to pkg/icefront (read from data.icefront)
422    o pkg/exf:
423      - replace CPP option ALLOW_EXF_OUTPUT_INTERP with run-time parameter
424        "exf_output_interp" (in namelist: EXF_NML_04); change output file name
425        (add suffix "_out" instead of a prefix); keep same record number as in
426        input file but always write record 1 first (to avoid a STOP in I/O S/R).
427        Change output file content by writing interpolated field before applying
428        land-sea mask (helpful for debug).
429      - 2 compon. vector interpolation with rotation: apply scaling factor on
430        each compon. (Eastward and Northward) just before rotation.
431    o pkg/bling:
432      - Cleaned package. Removed not needed code and comments.
433      - adjoint example now works
434        (MITgcm_contrib/verification_other/global_oce_biogeo_bling/code_ad)
435    o pkg/ptracers:
436      - add Bruno Deremble's code to complete the linear surface correction
437        for tracer conservation;
438      - enabled for individual ptracers by PTRACERS_linFSConserve(iTr)=.TRUE.
439    
440    checkpoint65y (2016/07/29)
441    o pkg/debug (stats):
442      - change GLOBAL_SUM to GLOBAL_SUM_TILE (result independent of tile to
443        proc/thread mapping);
444      - fix Min & Max for case where 1 thread has only empty tiles;
445      - use RL variable to count number of wet grid points (with big domain,
446        can be too large to fit into integer*4).
447    o pkg/monitor:
448      - use RL variable to count number of wet grid points (but used only for del2)
449      - add new routine to compute Advective CFL within tracer time-stepping with
450        writing delayed until next monitor output.
451    o pkg/obcs:
452      - fix bug in OBCS_BALANCE_FLOW (OBCS_balanceFacN misspelled OBCS_balanceFacW)
453    o pkg/cal:
454      - calandar-dump: treat case myTime < timePhase in the same way as in
455        eesupp/src/diff_phase_multiple.F (when not using calandar-dump).
456    o pkg/dic & seaice:
457      - fix compilation of ocean component for coupled atm+ocn model with
458        seaice dynamics & dic.
459    
460    checkpoint65x (2016/06/11)
461    o add a license text file in main MITgcm tree.
462    o added pkg/bling:
463      - intermediate complexity biogeochemical model
464      - see bling_description.txt for details
465      - verification experiment is global_oce_biogeo_bling (for now, in
466        Contrib/verification_other/); tested daily on baudelaire with gfortran.
467      - add entry point in pkg/gchem for new pkg "bling".
468    o pkg/seaice: fix tensile stength computation
469      - replace global field tensileStrength by tensileStrFac
470      - tensileStrFac can be computed once in S/R seaice_init_varia
471      - fortunately that does not affect any verification results
472    
473    checkpoint65w (2016/05/12)
474    o pkg/ctrl/ctrl.h: fix a comma in common block list, so that code compiles
475         with ECCO_CTRL_DEPRECATED defined
476    o verification/global_ocean.cs32x15:
477      - change secondary test "viscA4" to also test "selectP_inEOS_Zc=3"
478        with "selectNHfreeSurf=1".
479    o model/src (non-hydrostatic free-surface):
480      - More "natural" expression of NH free-surface term (case selectNHfreeSurf=1):
481        was: tmpSurf/(1+tmpSurf); changed to: 1/(1+Gamma) with Gamma=1/tmpSurf.
482      - Calculate surface vertical velocity after 2-D solver adjustment (accounts
483        for EmPmR if RealFreshWaterFlux); used in RHS (cg3d_b) if exactConserv
484        and used to compute dPhiNH (in post_cg3d.F) if selectNHfreeSurf=1.
485        This fixes EmPmR contribution when selectNHfreeSurf=1 & RealFreshWaterFlux.
486      - Update output (changes at machine truncation level) of verification exp:
487        exp4 (11 digits for cg2d), global_ocean.cs32x15.viscA4 (11.d),
488        short_surf_wave (13.d) and tutorial_deep_convection.smag3d (12.d).
489    o pkg/seaice: ITD code
490      - fix picking up from a single category model by initialising
491        heff/area/hsnowITD = 0. in seaice_itd_pickup.F
492      - split a long warning message in seaice_check_pickup.F into two lines,
493        because NEC SX-ACE cannot deal with the long line.
494    o model/src:
495      - fix missing dPhiNH in pressure_for_eos.F (case: selectP_inEOS_Zc=3)
496    o pkg/seaice:
497      - add missing checks for SEAICE_ALLOW_KRYLOV and SEAICE_ALLOW_BOTTOMDRAG
498    o pkg/seaice:
499      - add basal stress as parameterisation for grounding ice
500        following Lemieux et al. (2015)
501      - turn on by setting new parameter SEAICEbasalDragK2 to a value
502        larger than 0. Lemieux et al. (2015) recommend 15.
503      - The adjoint complains with extra recomputations so there is also a
504        new cpp-flag SEAICE_ALLOW_BOTTOMDRAG that is undefined by default in
505        order to postpone the problem
506      - compile the new code in lab_sea
507    o verification/halfpipe_streamice:
508      - update both TAF and OpenAD adm output (machine truncation differences)
509    
510    checkpoint65v (2016/04/08)
511    o verification/advect_xz:
512      - increase overlap size from 3 to 4 and add new secondary test for PQM
513        advection scheme (with mono & wino limiter).
514      - change main exp. to test PPM (with weno limiter) adv.scheme on Temp.
515    o model/src:
516      - new parameters "top_Pres" & "seaLev_Z" (replacing Ro_SeaLevel and recently
517        added phi0Ref) to set vertical axis origin and phiRef origin;
518        keep Ro_SeaLevel for backward compatibility (with a warning).
519       According to coordinate and fluid type:
520        OCN in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(1), @ the top)
521        ATM in Z: top_Pres(Ref) (=rhoConst*PhiRef(1)), seaLev_Z (=rF(Nr+1) @ bottom)
522        OCN in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(Nr+1)/g, @ the top)
523        ATM in P: top_Pres (=rF(Nr+1)), seaLev_Z (= PhiRef(1)/g, @ the bottom)
524      - remove Ro_SeaLevel from ATM experiment parameter files;
525      - in tutorial_global_oce_in_p, remove Ro_SeaLevel and set top_Pres to the
526        complement; update output.txt (changes at machine truncation level).
527    o pkg/seaice/seaice_evp.F
528      - simplify computation of deltaZ and zetaZ to simple averaging following
529        Bouillon et al. (2013). This removes a lot of code, but also changes
530        verification experiment lab_sea.hb87 -> updated
531    
532    checkpoint65u (2016/03/14)
533    o pkg/generic_advdiff:
534      - from Darren: add PPM and PQM advection schemes (number 40-42 and 50-52)
535        with 2 types of limiter (see: Engwirda & Kelley, submit. to JCP);
536        Note (from Darren): unlimited PPM/PQM scheme (40 & 50) are just for
537        testing and not for actual use.
538    o model/src:
539      - add parameter "phi0Ref" to specify reference [pressure/geo] potential at
540        origin r = rF(1);
541      - add options (parameter selectP_inEOS_Zc) to select which pressure to use
542        in EOS for height coordinate: enable to include NH Pressure or to use
543        more accurate pressure vertical profile; options not linked to EOS type
544        (as previously, e.g., JMD95P/JMD95Z) but set default according to EOS type;
545      - start to implement variable gravity (along vertical): for now, only with
546        z-coords (not even z*).
547      - add Ideal Gas equation of state for height coordinate.
548      - update OpenAD output (affected at machine truncation level) of exp:
549        global_ocean.90x40x15, OpenAD (std) and tutorial_global_oce_biogeo.
550    o pkg/exf:
551      - add ALLOW_EXF_OUTPUT_INTERP cpp switch to output the result
552        of exf interpolation (before any rescaling, rotation or interpolation
553        to velocity point) for each field that gets loaded from file. This option
554        identically mimics the input file organization (e.g. record numbers in year
555        by year input files) besides the change in horizontal grid.
556      - add rotateStressOnAgrid run-time switch so that wind stress fields
557        can be provided on the A-grid in zonal/meridional direction and
558        rotated on the fly. This only applies to the case when the exf
559        interpolation is off and rotateStressOnAgrid is false by default.
560    o model/src:
561      - rename internal parameter "useDynP_inEos_Zc" to "storePhiHyd4Phys" (since
562        it's also used with pkg/atm_phys) and add few more parameters (but still
563        inactive, src code yet to come)
564    
565    checkpoint65t (2016/02/10)
566    o pkg/atm_phys:
567      - from Ruth Geen: add optical depth dependence on CO2 concentration.
568    o model/src:
569      - fix vertical inter/extra-polation of density factor rhoFacF (for anelastic)
570        for the case setCenterDr=T (delRc set from "data"); add output of rhoFacC&F.
571        Update output of exp. deep_anelastic (changes at truncation level).
572    o tools:
573      - add a hack in "remove_comments_sed" (used only with TAF) for recent
574        version of OpenMPI (shipped with FC.23): comment out the new header
575        file "mpif-sizeof.h" which causes problems to TAF.
576    o pkg/seaice:
577      - change the termination criterion so that maxits (SEAICElinearIterMax)
578        has an effect
579      - unify iteration parameters for implicit solvers (JFNK and Picard)
580        SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS
581        SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER
582        SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner
583        SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner
584        SEAICEnonLinTol     replaces JFNKgamma_nonlin
585      - remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN
586      - add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and
587        use with SEAICEuseKrylov
588    o pkg/seaice/seaice_lsr.F
589        fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only
590        relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have
591        an effect.
592    o pkg/seaice: add two new parameters
593      - SEAICEuseLSR to simplify the logic in seaice_dynsolver (this
594        parameter is not in any namelist)
595      - SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as
596        a preconditioner for the non-linear Newton iteration of the JFNK
597        solver
598    o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT,
599      affects some experiments at truncation level:
600      - global_ocean.cs32x15.icedyn (11 digits),
601      - global_ocean.cs32x15.seaice (11 digits),
602      - seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update
603      - also update global_ocean.cs32x15 adjoint and tangent-linear results
604    o pkg/salt_plume & pkg/thsice:
605      - for coupled  set-up with pkg/thsice in ATM and pkg/salt_plume in OCN,
606        connect salt_plume flux to ATM-OCN coupling pkgs interface:
607       a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for
608         export to coupler interface) even without compiling pkg/salt_plume ;
609       b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field
610         (saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH.
611    o pkg/dic:
612      - use the updated seaice fraction (from seaice pkgs) for DIC forcing
613        instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE
614        called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD);
615      - move also update with values from ATM-OCN Coupler in the same new S/R
616        (previously done in ocn_apply_import.F).
617    o tools/adjoint_options:
618      - specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default)
619        has been changed on Jan 14, 2016.
620    o pkg/ggl90:
621      - add alternative discretisation of vertical shear (off by default), to
622        compute the mean (@ grid-cell center) of vertical shear compon instead of
623        vertical shear of mean flow (@ grid-cell center).
624      - add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated
625        results on adjacent faces of cubed-sphere grids; this fix the restart.
626    o pkg/atm_compon_interf:
627      - skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just
628        pass last value, stored directly before export to CPL ;
629        Note: this affects results of Coupled set-up where OCN uses useImportSLP=T
630      - remove atmSLPr from pickup files (no longer needed for restart)
631    
632    checkpoint65s (2016/01/13)
633    o eesupp & genmake2:
634       - first check for Function ETIME and, if it fails, then check for subroutine
635         ETIME and consistent output; use the appropriate version in timers.F
636    o model/src:
637      - to check restart test, add option to apply EXCH to U,V earlier, just before
638        integr_continuity; turned off by default.
639    o pkg/dic:
640      - remove CPP option USE_ATMOSCO2 (not needed)
641    o tools/tst_2+2:
642      - try to ignore difference between +0 and -0 in binary file, causing test
643        to fail for no good reason.
644    o eesupp & genmake2:
645      - put back modif from Jinxuan Zhu - change etime fct call to S/R call -
646        but also check (in genmake2) that test runs and returns meaningful results.
647    o coupler pkgs:
648      Finish implementation of optionally-exchanged variable switches (started on
649       Nov 12) with addition of few more exchanged fields, including 2-way exchange
650       of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice
651       advection in OCN component; this requires sequential coupling.
652      coupler (pkg/atm_ocn_coupler):
653      - add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS
654        routines (useful for debug).
655      - only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume
656         flux, DIC fields) if corresponding switch is ON.
657      - add option to export RunOff to OCN (to use for DIC river input)
658      - add 2-way thSIce vars exchange; check for consistent cpl_sequential setting.
659      components (pkg/atm_ & ocn_compon_interf):
660      - to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around
661        optionally exchanged fields; add a check & stop in cpl_readparms.F.
662        ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2;
663        OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice.
664      - rename:   fracIce     -> sIceFrac_cpl (<- match coupler var name)
665        + in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime.
666      - add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN.
667      - hold in common block coupler optionally-exchanged variable switch
668        and set default "useImportXXX" accordingly; + check & stop if inconsistent.
669      - add diagnostics for all imported fields from coupler (in both OCN & ATM);
670        this is intended to replace the OCN cplFldtave.* output files (not updated
671        to contain new additional exchanged fields).
672    o pkg/dic:
673      - fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code.
674    o pkg/thsice:
675      - when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading
676        and writing of thsice pickup files.
677    o pkg/atm_compon_interf:
678      - move all field individual export-call out of cpl_export_import_data.F
679        into new S/R ATM_EXPORT_FIELDS
680    o pkg/atm_compon_interf:
681      - store state variables (for now, only thSIce fields) just before beeing
682        exported (in cpl_export_import_data.F, like on ocean side) instead of from
683        atm_store_my_data.F like all exported fluxes.
684      - new version of pickup_cpl: write field names into meta file and read meta
685        file to find field postion in pickup. Also only write/read fields meeded for
686        restart (same logic as main pickup file ; also using pickupStrictlyMatch)
687    o pkg/dic:
688      - fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3.
689    o pkg/seaice: add new parameter SEAICEpressReplFac to choose between
690        pressure replacement method (=1., default) or original Hibler (1979) (=0.)
691        value can be from domain [0,1] to average between the two methods
692    o pkg/atm_phys:
693      - allow to provide 2-d map of albedo and mixed-layer depth from files (but
694        hold fixed in time).
695    
696    checkpoint65r (2015/12/21)
697    o pkg/seaice:
698        fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK
699        solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated
700    o pkg/seaice:
701      - fix a bug in computing areaS in (J-J -> J-1) that affects runs
702        when SEAICEscaleSurfStress=.TRUE.,
703      - apply areaW and areaS in S/R seaice_calc_lhs
704    o pkg/atm_phys:
705      - add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes
706        (shortwave & longwave, net & downward) and diagnostics of temp. tendency
707        for individual contribution (convection, LSC cond, radiation)
708      - add Ruth Geen etal, GRL 2016, radiation options (see paper supp.
709        information); activated with: solar_exponent=0. and wv_exponent=-1.
710    o pkg/ggl90:
711      - within IDEMIX add upper limit for horizontal group velocity to
712        avoid instability problems in the explicit horizontal diffusion term for
713        long time steps or high resolution
714    o pkg/diagnostics:
715      - simplify setting of local-array size in diagstats_output.F: uses "numLevels"
716        (from DIAGNOSTICS_SIZE.h) to allow to write out more than Nr levels.
717    o testreport:
718      - remove "-v" (verbose option) in default mpirun command.
719    o pkg/seaice/seaice_growth:
720      - catch potential division by zero in ITD code, does not change
721        verification results
722    o pkg/ecco:
723      - retire old codes to the Attic. The calls to retired functions are
724        left in a commented form in case they ever need to be re-activated.
725      - ecco_check.F: issue warning if any old CPP option is
726        defined that corresponds to retired codes -- then stop.
727    o pkg/atm_compon_interf:
728      - change seaice fraction (use for OCN dic surf.flux) stored and sent to
729        coupler: use last time-step value instead of average over cplSendFrq_iter
730        time-step, similar to what is done for seaIceMass.
731        This will affect results (pkg/dic) of coupled ATM-OCN+dic set-up.
732    o eesupp & genmake2:
733      - from Jinxuan Zhu: change etime fct call to S/R call (fix gfortran ETIME);
734        <= remove until a fix is found for some ifort version on ia32 machine.
735    o pkg/seaice/seaice_evp:
736      - refine residual computation
737    
738    checkpoint65q (2015/11/18)
739    o pkg/seaice/seaice_evp:
740      - fix residual computations so that they no longer affect the actual
741        simulation code
742      - fix seaice_readparams to be able to actually set new parameters
743        SEAICEaEVPcStar and SEAICEaEVPalphaMin, also fix logic a little
744    o model/src:
745      - fix wrong truncation (single prec) from "FLOAT" function in expressions
746        like: deltaT*FLOAT(myIter) when myIter is large:
747         a) replaced by DFLOAT (if not seen by TAF);
748         b) remove "FLOAT" and use implicit type conversion (if seen by TAF).
749    o pkg/aim_v23:
750      - write/read the expected CO2 pickups (from S/R AIM_DO_CO2): fix reading
751        when pickupSuff is set ; do write rolling pickups + at the end of the run.
752    o pkg/atm_ocn_coupler + ocn_compon_interf:
753      - in prep for using pkg/seaice Dyn in coupled set-up, implement sequential
754        coupling option-1: ATM -(cpl)-> OCN and then OCN -(cpl)-> ATM ;
755        add corresponding call in DO_OCEANIC_PHYS.
756    o coupler pkgs:
757      Start a new way to set-up optionally-exchanged variables (previously, only
758       there for exchange_DIC): switch on/off from 1 place, at run-time, in coupler
759       data.cpl (new) instead of at compile time in ATMIDS.h & OCNIDS.h ;
760       send switch to ATM & OCN compon before reading their own "data.cpl" (so that
761       compononent param default can be set accordingly).
762      Note: this new switch (cpl_exchange_[xxx]) is not a per variable switch
763       but rather applies to a group a fields (going both ways like for DIC)
764       and corresponds to an option of coupling config.
765      coupler (pkg/atm_ocn_coupler):
766      - change parameter file from "data" to "data.cpl" (in cpl_read_params.F),
767        and read namelist directly (without eessup S/R calls) instead of
768        in the very un-flexible old way, 1 param per line, in fixed order;
769      - add error-counter to track errors (e.g., missing "data.cpl") and to stop
770        cleanly in CPL_CHECK_CPLCONFIG
771      - add new coupling-exchange selectors (some not yet active) including
772        cpl_exchange_DIC (to set to 3 to replace atmCpl_exchange_DIC=T in ATMIDS.h
773                                             and ocnCpl_exchange_DIC=T in OCNIDS.h);
774      - add 2 new S/R (CPL_SEND_ATM/OCN_CPLPARMS) to send coupler-params to each
775        component ; called directly from coupler.F, after comp. registrations;
776      - rename few variable-ID names (in ATMIDS.h & OCNIDS.h):
777         atm/ocnSeaIceName --> atm/ocnSIceMassName ; atm/ocnFCO2Name ->
778          -> atm/ocnCO2FluxName ; atm/ocnWSpdName --> atm/ocnWindSpdName
779      components (pkg/atm_ & ocn_compon_interf):
780      - add ATM/OCN_CPL_OPTIONS.h in component pkgs and include the corresponding
781        CPP header file in all pkg source files.
782      - move checking of comp. configs out of cpl_exch_configs.F into new S/R
783        ATM/OCN_CHECK_CPLCONFIG;
784      - add error-counter to track errors (e.g., in "data.cpl") and to stop
785        cleanly in ATM/OCN_CHECK_CPLCONFIG;
786      - add new S/R CPL_IMPORT_CPLPARMS to import coupling-exchange selectors
787        from coupler ; called from initialise_fixed.F, after PACKAGES_BOOT and
788        before PACKAGES_READPARMS;
789      verification/cpl_aim+ocn/:
790      - update ATMIDS.h & OCNIDS.h (in shared_code) and use new parameter file
791        "data.cpl" for coupler (in input_cpl).
792    o eesupp/inc:
793      - change the MPI-global-sum default (in CPP_EEOPTIONS.h) to:
794        #define GLOBAL_SUM_ORDER_TILES (only affects MPI built of global_sum_tile.F)
795        to always cumulate tile local-sum in the same order (still uses
796        MPI_Allreduce like standard code).
797      - in verification experiment code, remove local CPP_EEOPTIONS.h_mpi files
798        that are now identical to standard version (in eesupp/inc).
799    o pkg/shelfice:
800      - add SHELFICETransCoeffTFile for initializing spatially varying
801        heat and salt transfer coefficients
802    o pkg/atm_compon_interf & ocn_compon_interf:
803      - combine into 1 (new) S/R CPL_EXPORT_IMPORT_DATA the two previous
804        S/R CPL_EXPORT_MY_DATA & CPL_IMPORT_EXTERNAL_DATA
805      - move bi,bj loops inside S/R OCN_STORE_MY_DATA
806    o pkg/atm_ocn_coupler:
807      - initialise to zero ATMVARS.h & OCNVARS.h arrays.
808    o pkg/rbcs:
809      - select RBCS-mask for Temp & Salt the same way as for pTracer ; this allows
810        to compile with maskLEN=1 when all tracers use the same RBCS-mask.
811      - add a short report (to STDOUT) about RBCS-mask settings.
812    
813    checkpoint65p (2015/10/23)
814    o pkg/seaice/seaice_evp.F: fix store directives and key computations, since
815        there is no adjoint test for EVP, we don't know what it does to the adjoint
816        solution, but at least there are no more recomputation warnings left
817    o pkg/seaice/seaice_evp.F: slight modification of averaging so that EVP stands
818        a chance of giving the same results as a fully converged VP (JFNK) solver
819    o tools/adjoint_options/adjoint_diva:
820      - fix bug (typo) in Tang-Linear FLAGS setting for MPI + DIVA
821    o pkg/streamice:
822      - spotted bug in streamice_driving_stress using dyG where should have been dxG
823    o pkg/exf:
824      - remove STOP statement that prevented to use wind or (wind-)stress
825        interpolation for constant-in-time forcing fields (wind/stress period = 0).
826    o pkg/seaice:
827      - replace SEAICE_EVP_USE_ADAPTATION by run time parameters, requires
828        5 additionals 2D fields and 6 new store directives
829      - change logic in seaice_readparms.F: EVP code can now be turned on in
830        various ways, setting SEAICE_deltaTev is no longer required,
831        alternatively set SEAICE_evpAlpha/Beta, SEAICEuseEVPstar, SEAICEuseEVPrev,
832        or SEAICEaEVPcoeff
833    o pkg/shelfice/shelfice_thermodynamics.F
834      - redefining uLoc/vLoc to u/v, instead of 2u/v
835    o pkg/seaice/seaice_evp.F: introduce "adaptive EVP" by Madlen Kimmritz
836      - this is an intermediate state of a truely converging EVP that has
837        the potential of outperforming implicit VP methods, I do not recommend
838        using it yet.
839      - for now, "adaptive EVP" is turned on by setting SEAICE_EVP_USE_ADAPTATION
840        and all parameters are hardwired
841      - for convergence it still requires very smooth regularisations, that means,
842        if SEAICE_DELTA_SMOOTHREG is defined, deltaCreg=deltaC+deltaMin, which is
843        different from the VP case with deltaCreg=sqrt(deltaC**2+deltaMin**2); also
844        specific averaging appears to be required, still subject to tuning
845      - still needs cleaning and I need to turn parameter into runtime parameters
846      - add code to compute and print residuals of iteration, compile with
847        defining ALLOW_SEAICE_EVP_RESIDUAL to enable it
848    o pkg/seaice/seaice_evp.F: fix a bug (factor of four in front of e12Csq)
849      that entered with r1.54 on Sep04, 2015, -> update results
850    
851    checkpoint65o (2015/09/14)
852    o pkg/mom_vecinv & mom_common:
853      - add deep-atmosphere geometry factor in mom_calc_visc.F + in routines
854        called from there.
855      - add anelastic and deep-atmosphere geometry factor in pkg/mom_vecinv ; this
856        allows to use Vector-Invariant form in deep atmos and anelastic formulation
857    o pkg/seaice: introduce fast ice parameterisation following Itkin et al. (2015)
858      and Koenig-Beatty+Holland (2012)
859      - two new parameters SEAICE_tensilFac and SEAICE_tensilDepth
860      - global 2D field tensileStrength, computed in seaice_calc_ice_strength
861      - requires an extra input argument for S/R seaice_calc_viscosities
862      - tensileStrength's depth dependence is different from Itkin et al. (2015)
863        (to be changed and played with, for now exponential)
864    o pkg/seaice: introduce new parameter SEAICEscaleSurfStress (default = .FALSE.)
865      - if TRUE scale ice-ocean and ice-atmosphere stress acting on sea ice
866        by AREA according to Connelly et al. (2004), JPO.
867      - For EVP and the LSR solver, the implicit part of the drag term is
868        the only non-zero term in the denominator when there is no ice (which
869        prevented running the model with zero ice-ocean drag). If
870        SEAICEscaleSurfStress = .TRUE., this results in a division by zero
871        (or zero main diagonals BU/BV) which need to be caught. A practical
872        consequence is that for open water, the momentum equation reduce
873        to trivially 0 = 0 + 0 (for EVP). For LSR, BU/BV are reset to 1, if
874        they happen to be zero, often leading to a non-zero solution over
875        open water.
876    o pkg/seaice: revise EVP code (seaice_evp.F) in preparation for a more
877        efficient EVP method.
878      - introduce area-weighted averages for e12 (analogously to
879        seaice_calc_viscosities.F); this totally changes lab_sea.hb87 (2 digits
880        remain, but also changing the order of terms in the previous average
881        changed the results as much) -> update experiment
882      - add SEAICE_DELTA_SMOOTHREG code
883      - disentangle computation of zetaC/deltaC and zetaZ/deltaZ, also for
884        TEM-code
885      - adjust loop bounds so that only required fields are computed
886      - add new averaging code for zetaZ/deltaZ (again similar to
887        seaice_calc_viscosities.F), inactive by default for now (will change
888        results again), but will replace old code eventually
889    o eesupp/src:
890      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
891        to always cumulate tile local-sum in the same order
892        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
893        Still uses MPI_Allreduce (like standard code) but on array of tiles
894        and should be faster than GLOBAL_SUM_SEND_RECV code.
895      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
896        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
897      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 14 more exp.:
898         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
899         fizhi-cs-aqualev20, fizhi-gridalt-hs, global_ocean_ebm, matrix_example,
900         natl_box, solid-body.cs-32x32x1, tutorial_advection_in_gyre,
901         tutorial_baroclinic_gyre and tutorial_held_suarez_cs.
902    
903    checkpoint65n (2015/07/29)
904    o pkg/thsice:
905      - add a warning when used with pkg/aim but without updating SST
906        (stepFwd_oceMxL=F & useCoupler=F & tauRelax_MxL<>-1 ).
907    o pkg/offline:
908      - change where Offline-Fields are loaded, from load_fields_driver.F to
909        directly within FORWARD_STEP, just after updating iter number and time;
910      - move setting of GM and KPP diffusivity out of OFFLINE_FIELDS_LOAD into new
911        S/R OFFLINE_GET_DIFFUS that is called towards the end of DO_OCEANIC_PHYS;
912       These changes allow:
913        a) to recover exactly on-line results using deltaToffline=deltaTClock,
914        tested (using offlineIter0= nIter0 -1 and offlineTimeOffset= -deltaT/2)
915        both with Lin & Non-Lin Free-Surf, both with staggerTimeStep & synchronous
916        time-step, both with GM & KPP files and with recomputing these fields;
917        b) no needs to switch on staggerTimeStep anymore;
918        c) simplify rescaling of offline horiz. velocity with Non-Lin Free-Surf.
919      - update output of experiment tutorial_dic_adjoffline (only 3 digits left).
920    o pkg/offline:
921      - change (rarely used) offset-iteration parameter to an offset time (in s):
922        can easily recover previous offset-iter effect by setting offset-time
923        (offlineTimeOffset) to offset-iter x deltaToffline;
924      - do not turn-off Temp & Salinity surface relaxation when using KPP (used
925        in KPP as part of surface buoyancy forcing) in offline run.
926      - fix ptracers KPP non-local term in the case where KPP is re-computed.
927    o OpenAD
928      - Adding preliminary ggl90 test to OpenAD verification.
929        Config. with ggl90 currently diverges after 64 time steps
930        so will need more work to become more stable
931      - Adding preliminary kpp test to OpenAD verification.
932        required small tweakes in kpp_routines.F
933      - Merge and update from Krishna Narayanan's contrib area:
934        * Add one variable for preliminary OpenAD DIVA
935        * Add replacement time-stepping for OpenAD DIVA
936        * genmake2 flag -diva (but only for OpenAD; preliminary)
937        * required modifs for OAD_support
938        successful preliminary test for tutorial_global_oce_biogeo/
939    o pkg/seaice:
940      - initialise deltaC in seaice_lsr, cosmetic changes in seaice_lsr
941      - add cpp-flag SEAICE_DELTA_SMOOTHREG for option of regularising
942        delta with a smooth function in s/r seaice_calc_viscosity
943        (no effect on EVP)
944      - rename local suffix "sqr" into "sq" for more consistent variable names
945    o pkg/seaice:
946        add new parameter SEAICE_deltaMin that is used ***only***
947        for regularizing Delta (and nothing else, like the parameter
948        which is also used for all sorts of things SEAICE_EPS).
949        Defaults to SEAICE_EPS for backward compatibility only.
950    o pkg/seaice: replace erroneously storing e12Csqr on the wrong tape with
951        the wrong key by inialising it before use -> fixes a recomputation
952        problem but does not fix the gradient
953    o pkg/layers:
954      - move resetting of flux arrays to outside the iLa loop
955        (this caused layers_diapycnal to not work with more than one layer coord.)
956      - fix bug in calculation of layers_recip_delta in layers_init_fixed.F
957    o pkg/layers:
958      - remove from common block 3D layers fields (used to diagnose transport
959        in tracer coords) and declare them as local arrays in layers_calc.F
960    o pkg/seaice:
961      - Rename SEAICE_VECTORIZE_LSR_ZEBRA to SEAICE_LSR_ZEBRA and define it
962        in lab_sea forward experiment (changes results -> updated)
963      - update adjoint experiment lab_sea after cleaning up seaice_lsr_tridiagu/v
964    o pkg/seaice: modify seaice_lsr.F in order to improve the gradient
965       computations; for SEAICE_VECTORIZE_LSR
966      - move the loops over which the tridiagonal solvers (seaice_lsr_tridiagu/v)
967        sweep to the outside,
968      - remove store directives and add "CADJ loop sequential" directives
969        in analogy to model/src/solve_tridiagonal.F
970      - replace many "#ifdef SEAICE_VECTORIZE_LSR_ZEBRA" by variable loop
971        boundaries to yield more readable code. This has also the charming side
972        effect that your can use SEAICE_VECTORIZE_LSR_ZEBRA without
973        SEAICE_VECTORIZE_LSR (i.e. adjoint without recomputations in
974        seaice_lsr_tridiagu/v now requires either of these flags, vectorization
975        still requires SEAICE_VECTORIZE_LSR with SEAICE_VECTORIZE_LSR_ZEBRA as
976        an additional option)
977       The tridiagonal solvers are now completely analoguous to solve_tridiagonal.F
978       but the adjoint gradients (which are affected by this change) still explode.
979    o coupler (atm & ocn _compon_interf):
980      - avoid using Exch2 IO mapping if not suitable.
981    
982    checkpoint65m (2015/06/15)
983    o pkg/layers:
984      - clean-up old parameters setting (from Sep 2012):
985        + remove old parameters setting from common block (declared locally);
986        + stop if any old parameter is mixed with new parameters;
987        + check for valid or consistent parameter setting (e.g., layers_name)
988      - check that layers_bounds for Pot.Density are in the right range;
989        this is supposed to catch un-updated setting after recently shifting
990        potential density field "prho" by -1000 (now in "sigma" scale).
991    o pkg/layers:
992      - Added missing call to layers_fill for keeping track of tottend in
993        pkg/diagnostics/diagnostics_fill_state.F
994    o pkg/layers:
995      - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
996        of diapycnal fluxes
997    o pkg/layers:
998      - reverted changes to interpolation to previous treatment; there
999        was never actually a problem
1000    o pkg/layers:
1001      - fix interpolation of layers tracers in the presence of partial cells
1002      - add lots of new functionality to compute water mass transformation
1003        (enabled by CPP flag LAYERS_THERMODYNAMICS)
1004      - add new calls from main code (diags_oceanic_surf_flux.F,
1005        thermodynamics.F, impldiff.F) and gad to save the necessary fields
1006        for layers_thermodynamics calculations
1007    o pkg/ptracers:
1008      - add capability of stepping a passive tracer forward without advection
1009        by setting PTRACERS_advScheme to 0.
1010    o pkg/diagnostics:
1011      - add few (threads) _BARRIER around any update of "diag_pkgStatus".
1012    o pkg/layers:
1013      - shift potential density field "prho" by -1000 for density layer averaging so
1014        that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
1015        Note that density bin boundaries (layers_bounds in data.layers) have
1016        to be set accordingly (i.e., shifted, in sigma scale).
1017    o pkg/layers:
1018      - fix snap-shot output of layer thickness @ V.pt and output of pot.density
1019      - fix calculation of layer non-weighted velocity and layer probability
1020      - add diagnostics for pot.density used for layer averaging
1021    o pkg/seaice:
1022      - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
1023        positiveness, modify a few comments and improve variable names,
1024      - the changed computation of deltaC affects most seaice-related
1025        experiments at the truncation level.
1026        seaice_itd.thermo is affected by far the most, with
1027        only 7 digits of agreement remaining; update experiments.
1028    
1029    checkpoint65l (2015/05/04)
1030    o pkg/shelfice:
1031      - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
1032        factor drKp1 to zero where it is negative (ie. do not use
1033        SHELFICEBoundaryLayer if hFacC>1)
1034      - the same for factor drLoc in shelfice_forcing.F
1035    o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
1036        with modules in ptracers, when using testreport option "-small_f"
1037    o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
1038      - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
1039    o verification/testreport
1040      - add new option -small_f
1041        with this option testreport first makes the target small_f (*.f files)
1042        before running make (all). This is useful for explicit inlining when
1043        all sources need to be full available.
1044    o pkg/exf/exf_interp.F:
1045        remove previous changes related to reverse (decreasing) input grids latitude
1046    
1047    checkpoint65k (2015/04/01)
1048    o pkg/ecco:
1049        fix missing cosphi initialization; use eccoiter in place of optimcycle;
1050        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1051        instead of active read/write
1052    o pkg/ctrl:
1053        if autodiff is not compiled then use READ_REC_XY_RL/READ_REC_XYZ_RL
1054        instead of active read/write.
1055    o pkg/autodiff: make autodiff_readparms.F and autodiff_whtapeio_sync.F
1056        return if .NOT.useAUTODIFF
1057    o pkg/seaice: add CPP brackets (cost function related).
1058    o model/src:
1059        add useAUTODIFF run time switch.
1060    o pkg/exf/exf_interp.F:
1061        add code to allow input grids with latitude starting in the north (i.e. when
1062        j=1 corresponds to northern edge of field); modify global_with_exf to test
1063        this feature.
1064    o verification/testreport:
1065      - replace "grep -A3" with POSIX conformal sed command, because there are
1066        implementations of grep that cannot do contextual searches
1067      - replace "cat -n" by "nl" (two occurrences), because not all implementations
1068        of "cat" have the option "-n"
1069    o model/src:
1070        add new file gsw_teos10.F that contains 3 functions, more or less a copy
1071        of the gsw_toolbox.f90 of the TEOS-10 fortran interface, that are used to
1072        convert from conservative to potential temperature. For now they are not
1073        called anywhere.
1074    o pkg/ggl90: make "useIDEMIX" useful
1075      - re-organize code in s/r ggl90_calc a little to move computations that
1076        are different for idemix into separate loops (changes verification
1077        experiment idemix at truncation level, 12 digits remain -> updated)
1078      - requires 2 new 2D fields KappaM, verticalShear
1079      - make hFacI and recip_hFacI local 3D variables that are passed to
1080        s/r ggl90_idemix
1081      - fix and improve some comments
1082    
1083    checkpoint65j (2015/02/25)
1084    o pkg/openad
1085      - synchronize seawater.F with version in model/src: replace routine
1086        body of sw_temp by calling sw_ptmp and fix/add a few comments.
1087    o pkg/mnc:
1088      - change default value of pickup_read/write_mnc params to FALSE
1089        (since few features are missing in reading MNC pickup files).
1090    o model/src:
1091      - change default (background) vertical diffusivity for salt to be the
1092        temperature (background) vertical diffusivity.
1093      - change background vertical diffusivity in vertical mixing pkgs ggl90,
1094        kl10, my82 and pp81 from temperature diffusivity to salinity diffusivity.
1095        This makes ptracers default diffusivity (that uses salt diffKr) more
1096        consistent with vertical mixing schemes.
1097    o verification/testreport:
1098      - fix typo in "-pcls" option ;
1099      - put temp files in /tmp (instead of in local dir)
1100      - add option "-ncad" to use genmake2 new option "-nocat4ad"
1101      - allow to use "-j" option (for multi-procs make) for AD, OAD and TLM.
1102    o pkg/ggl90 (idemix code):
1103      - apply few fixes ; add some missing "_d 0" ; update output of exp.
1104        global_ocean.90x40x15.idemix
1105    o OpenAD
1106      - enable active file I/O and begin removal of work-around code
1107        for OpenAD for handling control variables (memory vs. active files)
1108      - new CPP options file OPENAD_OPTIONS.h
1109      - revert to genarr2d gradient check for hs94.1x64x5
1110      - (genarr3d tested by tutorial_global_oce_biogeo, tutorial_tracer_adjsens)
1111      - gentim2d works for halfpipe_streamice but not yet hs94.1x64x5
1112    o tools/genmake2:
1113      - add option for an alternative Makefile (from Martin) where multiple
1114        source files are sent to TAF (instead of all in one file).
1115    o pkg/ggl90: add IDEMIX (Olbers and Eden, 2013)
1116      - code provided by Carsten Eden as an extension of ggl90
1117      - so far the code is turned on within ggl90 by setting a CPP-flag at
1118        compile time; a runtime flag implementation is not yet complete
1119      - tested in new verification experiment global_ocean.90x40x15.idemix
1120    o verification:
1121      - reduce length of the AD test run by half for experiments
1122        global_ocean.cs32x15 (std + thsice) and isomip
1123      - enable active file I/O for OpenAD, adjust verifications accordingly
1124      - halfpipe_streamice: change gradient check from genarr2d to gentim2d
1125    o verification/testreport:
1126      - fix two non-POSIX sed statements so that there are no error messages
1127        on Mac OS X
1128      - replace hostname -s with hostname | sed 's/\..*$//'
1129    o model/src/seawater.F:
1130      - simplify SW_TEMP to just calling SW_PTMP with P and PR exchanged
1131        (following the matlab code), which would have avoided the bug caught
1132        by Matt (see below) in the first place
1133    o pkg/shelfice:
1134      - implement alternative discretisation of quadratic drag (selectBotDragQuadr)
1135        and true distance in no-slip BC (bottomVisc_pCell) similar to bottom-drag.
1136      - fix sign of friction tendency (no-slip BC) and fix u,v drag for thin
1137        ice-shelf case (i.e., within surface level).
1138      - add config summary in shelfice_check.F
1139      - remove global variable recip_SHELFICElatentHeat and replace by a local
1140        variable recip_latentHeat
1141      - introduce diagnostics for friction velocity uStar (in case of
1142        SHELFICEuseGammaFrict)
1143      - change verification experiment isomip.htd:
1144        + start from pickup (as input_ad at nIter0=8640)
1145        + start from SHELFICEmassFile instead of SHELFICEloadAnomaly file
1146        + test SHELFICEuseGammaFrict = .TRUE.
1147        + test SHELFICEadvDiffHeatFlux = .TRUE.
1148    o model/src:
1149      - fix bug (Thanks to Matt) in function SW_TEMP (to convert Pot.Temp to
1150        in-situ Temp) and in routine SW_TEMP (in pkg/openad);
1151        update output of experiments global_with_exf.yearly and isomip (all 6).
1152    o pkg/shelfice:
1153      - change setting of kTopC to also be zero where there is no ice-shelf.
1154      - zero out surface forcing arrays (for now, for T & S + EmPmR) where
1155        ice-shelf is.
1156      - first attempt to get RealFreshWaterFlux effects: for now, only without
1157        SHELFICEboundaryLayer ; not consistent if using synchronous time-stepping.
1158    o pkg/seaice: add the option to prescribe a fixed thickness PDF
1159      for thermodynamic calculations
1160      - because of divisions of the type 7/7 not exactly equal to 1, this change
1161        affects results of some verification experiments by up to 4 digits:
1162        global_ocean.cs32x15.seaice, lab_sea, lab_sea.fd, lab_sea.salt_plume,
1163        seaice_obcs, seaice_obcs.seaiceSponge, seaice_obcs.tides
1164        adjoint: lab_sea, lab_sea.noseaicedyn
1165        -> updated
1166    
1167    checkpoint65i (2015/01/23)
1168    o model/src:
1169      - change units of frictionHeating field from W to W/m^2
1170      - fix bug in frictional heating from stratospheric drag in
1171        S/R ATM_PHYS_TENDENCY_APPLY_V
1172      - with synchronous time-stepping: move resetting to zero of frictionHeating
1173        field from load_fields_driver.F to thermodynamics.F ;
1174      - add diagnostics for frictional heating.
1175    o model/src & gmredi K3D:
1176      - add frictionHeating field to pickup-files (for synchronous time-stepping)
1177      - move ALLOW_EDDYPSI block out of DYNVARS.h and merge it into FFIELDS.h
1178      - rename uMean,vMean --> uEulerMean,vEulerMean (+ change diagnostics name
1179        and name in pickup file).
1180      - fix arguments of few DIAGNOSTICS_FILL calls in gmredi_k3d.F
1181    o model/src:
1182      - move (from ini_forcing.F) initialisation of all arrays in header file
1183        FFIELDS.h into new S/R ini_ffields.F ; this fix broken restart
1184        (since Nov 2012) with option selectAddFluid=1.
1185    o pkg/shelfice:
1186      - change units (+ document) of newly added field "shelfIceMassDynTendency"
1187      - upgrade from _RS to _RL shelficeMass & shelficeLoadAnomaly arrays.
1188    o pkg/obcs: re-organize obcs_calc_stevens.F to prepare for passive tracers
1189    o pkg/seaice: two new runtime parameters:
1190      - SEAICE_cStar replaces the hard wired "20" in the strength formulation,
1191        long overdue
1192      - SEAICE_tensilFac: preparation for Koenig-Beatty+Holland (2012)
1193        parameterization of tensil stress for fast ice (does not do anything yet)
1194    o pkg/seaice/seaice_check.F: left over from restricted addtive Schwarz method
1195        for LSR: move checking overlaps out of JFNK-if-block
1196    o pkg/atm_phys:
1197      - move copy of grid and dynamical fields out of atm_phys_driver.F into
1198        new S/R ATM_PHYS_DYN2PHYS.
1199      - fix level height for Linear Free-Surf case (to be consistent with
1200        fixed-in-time pressure levels).
1201    o pkg/mom_common (bottomdrag):
1202      - average bottomDragFld (ALLOW_BOTTOMDRAG_CONTROL) from grid-cell center
1203        to correct location (U & V point) in S/R MOM_U/V_BOTTOMDRAG;
1204        update output (adm & tlm) of experiment global_ocean.90x40x15.bottomdrag.
1205    o pkg/shelfice (u/v_drag):
1206      - add one argument (the other velocity component) to S/R SHELFICE_U/V_DRAG;
1207      - use SHELFICEDragLinear & SHELFICEDragQuadratic in shelfice_v_drag.F
1208        (now similar to shelfice_u_drag.F)
1209      - remove condition on bottomDragTerms when calling SHELFICE_U/V_DRAG
1210        from mom_vecinv.F (similar to mom_fluxform calls).
1211    o pkg/mom_common (bottomdrag):
1212      - add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
1213      - add options for alternative discretisation of velocity norm in quadratic
1214        bottom drag: averaging of grid-cell-center KE to U.point and V.point
1215        (selectBotDragQuadr=0, original code) can produce noisy patterns; this
1216        improves when averaging only the other component (e.g. vVel for U bottom
1217        drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
1218      - add options (bottomVisc_pCell) to account for partial-cell in bottom
1219        friction (no-slip BC) thus getting the true distance from the bottom;
1220        off by default since this also reduces model stability (explicit bottom
1221        friction). Changes produce different machine truncation with linear-drag
1222        + no-slip BC: update output of experiments exp4.stevens (10 digits) and
1223        front_relax (bvp & mxl, 10 & 11 digits).
1224    o model/src & mom pkgs:
1225      - add one more level to vertical viscosity local arrays (Nr+1, previously Nr)
1226        since no-slip bottom BC uses viscosity @ k+1 to update velocity @ level k
1227      - for now and until vertical mixing scheme are updated to fill up level Nr+1,
1228        just copy level Nr value to level Nr+1.
1229    o doc:
1230      - add notes form Abhisek Chakraborty on how to close Heat & Salt budgets.
1231    o pkg/shelfice:
1232      - shelfice_init_varia.F, shelfice_init_fixed.F, shelfice_readparms.F,
1233        SHELFICE.h: move array shelficemass to init_varia, initialise
1234        from array shelficemassinit, which is set in init_fixed and
1235        has option to be set from file; introduce array
1236        shelficeMassDynTend array, set thru file in init_fixed
1237      - NEW FILE: shelfice_step_icemass.F: update shelficemass from either
1238        shelfIceFreshWaterFlux and shelficeMassDynTend or H_streamice in
1239        pkg/streamice
1240      - shelfice_thermodynamics.F: call shelfice_step_icemass if
1241        SHELFICEMassStepping = .true.
1242      - shelfice_ad_diff.list: add new subroutine shelfice_step_icemass.f
1243    
1244    checkpoint65h (2014/12/17)
1245    o verification/global_ocean.90x40x15, global_ocean_ebm:
1246      - update to generic controls.
1247    o pkg/ctrl:
1248      - ctrl_map_ini_genarr.F: test for igen>0
1249      - ctrl_init_variables.F: add call to CTRL_MAP_INI_GENTIM2D.
1250      - move gentim2d part of ctrl_map_ini_genarr.F to
1251        new separate routine : ctrl_map_ini_gentim2d.F
1252      - ctrl_cost_driver.F,ctrl_init.F ctrl_map_ini_genarr.F:
1253        add time variable weights and cyclic controls (time mean,
1254        seasonal cycle, etc) capabilities to gentim2d
1255    o pkg/ecco:
1256      - move reading of error, conversion to weights from
1257        ecco_cost_init_fixed.F to ecco_toolbox.F (ecco_readwei)
1258    o global_oce_llc90, cs32:
1259      - activte sbo.
1260      - CTRL_SIZE.h : add maxCtrlProc.
1261      - activate the new genctrl capabilities.
1262      - update following reorganization of global_oce_input_fields.tar.gz  
1263    o pkg/ctrl/ctrl_ad_diff.list:
1264      - add missing ctrl_init_rec.f
1265    o tools/OAD_support/keepOriginal:
1266      - add ctrl_init_rec.F
1267    o model/src/the_main_loop.F, pkg/ctrl/ctrl_map_ini_genarr.F:
1268      - avoid recomputations of xx_gentim2d_dummy.
1269    o momentum diagnostics:
1270      - move filling of diagnostics Um_Diss & Vm_Diss from mom_fluxform.F and
1271        mom_vecinv.F to timestep.F (to include Smag-3D contribution).
1272    o pkg/seaice/seaice_lsr.F:
1273      - fix computation of BU/BV, make sure they are non-zero, only necessary
1274        for cubed sphere exchanges and SEAICE_OLx/y>0.
1275        This makes calling s/r fill_cs_corner_rl obsolete (removed).
1276    o verification/global_ocean.cs32x15/input.seaice
1277      - add test for strong implicit coupling and restricted addtive Schwarz
1278        methods for LSR
1279      - update results/output.seaice.txt
1280    o verification/tutorial_global_oce_biogeo:
1281      - AD & OAD set-up: switch off ALLOW_OLD_VIRTUALFLUX (like in fwd set-up)
1282        and set PTRACERS_EvPrRn(1,2) to zero (for DIC & ALK);
1283        update output_adm,_oadm,_tlm.txt
1284    o pkg/dic:
1285      - change default to "#undef ALLOW_OLD_VIRTUALFLUX" in DIC_OPTIONS.h
1286      - add a stop when ALLOW_OLD_VIRTUALFLUX is defined and PTRACERS_EvPrRn
1287        for tracer 1 & 2 is set (to avoid double counting of dilution effect).
1288    o verification/tutorial_global_oce_biogeo:
1289      - AD & OAD set-up: do not set PTRACERS_EvPrRn for tracer 1 & 2 since
1290        dilution is already added by pkg/dic ALLOW_OLD_VIRTUALFLUX ;
1291        update output_adm,_oadm,_tlm.txt
1292    o eesupp/src:
1293      - add fill_cs_corner_rl.F (_RL-copy of fill_cs_corner_rs.F)
1294        and call it in seaice_lsr when using nonzero SEAICE_OLx/y
1295    o pkg/seaice: introduce strongly implicit coupling, intended for stabilizing
1296      LSR (following Hutchings et al. 2004)
1297      - introduce zetaZ as a global variable (requires adjustments in
1298        seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
1299        in seaice_calc_viscosities.F
1300      - new flag SEAICEuseStrImpCpl (default off)
1301      - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
1302        momentum equations
1303      - JFNK-solver (preconditioner) adjusted to allow using this method
1304        (where it does not have any positive effect)
1305    o pkg/seaice
1306      - add overlap for restrictive additive Schwartz method also to LSR, but
1307        turn it off by default (because it only seems to work for non-cubed
1308        sphere/llc topologies)
1309    o pkg/autodiff
1310      - add extra exchanges in addummy_in_steppging also for mnc output
1311    o pkg/seaice:
1312      - add extra exchanges before dumping adjoint fields in seaice_ad_dump.F
1313        to avoid stripes in the adjoint output (similar to addummy_in_stepping.F)
1314    o pkg/obcs:
1315      - add option to specify domain-connected piece Id along OB though files
1316        (for now, only used to diagnose PhiVel; default =1 -> global correction)
1317      - modify obcs_diag_balance.F to process each connected-part separately;
1318        exclude OB where Id = 0 but keep the full divergence there (-> constant
1319        Psi along this portion of OB and all inflow derived from grad(Phi))
1320      - add example of OB-conect files in verification/so_box_biogeo/input.
1321    o pkg/diagnostics:
1322      - improve treatment of Open-Boundaries in Velocity-Potential calculation:
1323      a) use non zero matrix element across OB and solve for Phi 1 grid point
1324         outside OB (i.e, where tracer OBCS are applied).
1325      b) global imbalance of inFlow/outFlow across OB: instead of modifying
1326         velocity across OB, spread it uniformly along the OB in the RHS.
1327    
1328    checkpoint65g (2014/11/19)
1329    o pkg/diagnostcis:
1330      - add preconditioner off-diagonal factor (diagCG_pcOffDFac) as run-time param
1331    o pkg/my82,pp81,kl10:
1332      - fix ALLOW_3D_DIFFKR implementation (previously had no effect): use 3-D
1333        field diffKr as background diffusivity to set minimum diffusivity value.
1334    o pkg/seaice:
1335      - add new parameter SEAICEuseEVPrev (for revisited EVP by
1336        Bouillon et al 2013)
1337      - add SEAICE_evpAlpha/Beta to namelist
1338      - modify seaice_evp code to able to use SEAICEuseEVPrev. These changes
1339        involve trivial re-ordering of divisions/multiplications that should not
1340        have any effects, but ... they do change the results of lab_sea.hb87 so
1341        that only 2 digits of agreement remain, in line with the general
1342        instability/fragility of the evp-code. For now, I do not care and just
1343        update the verification experiment
1344    o pkg/ctrl : add generic pre-processing (xx_genarr2d_preproc etc)
1345      - remove xx_genarr2d_numsmooth etc
1346      - use xx_genarr2d_preproc etc instead
1347      - carry out smooth_correl2D at initialization stage rather than during
1348        time stepping.
1349      - get smoothOpNb from xx_gentim2d_preproc
1350    o global_oce_cs32 :
1351      - add test of generic ecco capabilities.
1352    o pkg/exf/exf_getsurfacefluxes.F :
1353      - add to tmpUE/tmpVN rather than re-initializing them (conventional behavior).
1354    o pkg/ctrl,ecco :
1355      - omit un-necessary arguments to ctrl_cost_gen.F unless ECCO_CTRL_DEPRECATED
1356        is defined.
1357    o pkg/seaice: add diagnostics for Delta (deformation parameter)
1358    o model/src:
1359      - when ALLOW_3D_DIFFKR is defined, add a Warning if any of the vertical
1360        diffusivity (background) is specified but ignored.
1361    o verification:
1362      - in testreport, convert hostname to lower case for default output dir name
1363    o model, pkg : add useCTRL, useECCO parameters (on/off run time switch).
1364    o pkg/dic: add modifications from Hajoon:
1365      - add iron sedimentation flux function of the flux of PO4 out of bottom layer
1366      - light attenuation: add self-shading effect by climatological Chlorophyll
1367        (read from file).
1368    o pkg/seaice/seaice_preconditioner.F : fix cpp flags, so that code also
1369        compiles when SEAICE_ALLOW_DYNAMICS is undefined
1370    o global_oce_llc90,cs32 : ecco_v4 verification exps now use separate
1371        AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h, ECCO_OPTIONS.h rather than
1372        ECCO_CPPOPTIONS.h (i.e. replacing the deprecated, circumvoluted,
1373        approach where CPP_OPTIONS.h includes an omnipotent
1374        ECCO_CPPOPTIONS.h that superseeds pkgs '_OPTIONS.h').
1375    o pkg/ctrl/ctrl_map_ini_genarr.F : include GMREDI_OPTIONS.h where
1376        ALLOW_3D_KAPGM, ALLOW_3D_KAPREDI (to be added later) belong.
1377    o pkg/seaice/SEAICE_SIZE.h : replace ALLOW_AUTODIFF_TAMC with ALLOW_AUTODIFF
1378        to avoid needing AUTODIFF_OPTIONS.h anytime SEAICE_SIZE.h is included
1379        (it seems that THSICE_SIZE.h, PTRACERS_SIZE.h have the same issue...)
1380    o model/src, pkg/smooth, profiles, salt_plume, seaice, exf, ecco, ctrl :
1381      add ECCO_OPTIONS.h, AUTODIFF_OPTIONS.h, CTRL_OPTIONS.h when needed
1382      - ECCO_OPTIONS.h is needed when including ecco_cost.h, ecco.h
1383      - AUTODIFF_OPTIONS.h is needed when including tamc.h, tamc_keys.h
1384      - CTRL_OPTIONS.h is needed when including ctrl.h, optim.h, etc
1385    o pkg/ctrl,ecco,exf :
1386      - remove variables associated with NON-generic costs,
1387        unless ECCO_CTRL_DEPRECATED is defined.
1388      - remove NON-generic NON-obcs controls,
1389        unless ECCO_CTRL_DEPRECATED is defined.
1390    o pkg/ctrl : added ctrl_local_params.h
1391    o pkg/ecco : added ecco_local_params.h
1392    o verification : added ECCO_CTRL_DEPRECATED to most as and oad
1393        experiments, which will progressively be removed once the
1394        experiments are revised to use only generic controls/costs.
1395    
1396    checkpoint65f (2014/10/13)
1397    o pkg/ctrl, ecco, seaice : minor changes in headers

1403        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1404        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1405      - cost_gencal.F (new) : determine filnames and records.
1406      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1407      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1408        and exploit the above functions leading to more compact code.
1409      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1410      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1411        using_ers, using_gfo, using_mdt is now only defined within gencost)
1412    o pkg/ecco: extend generic cost capabilities
1413      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1414        capabilities via gencost_preproc (+ _c,_i,_r related params),
1415        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1416        gencost_outputlevel arguments to cost_generic
1417      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1418        and active_read, making room for gencost_preproc to take effect.
1419        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1420      - pkg/ecco/cost_generic.F :
1421        compute and store misfit maks*(model-data) in localdif that is
1422        then used in cost and for output, output misfit if outlev.GT.0
1423      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1424        rather gencost_barfile for deciding whether to write barfile
1425      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1426      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1427        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1428      - pkg/ecco/ecco_summary.F : report gencost variables
1429      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1430    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1431    o pkg/ecco: internal re-organization
1432      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1433        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1434        mv relevant variables definition from ecco_cost.h to ecco.h,
1435        make sure gencost routines only include ecco.h)
1436      - throughout : add missing CCP switches, rm unused variables,
1437        and rm un-necessary CPP switches
1438      - throughout gencost routines : replace modelstartdate with
1439        gencost_startdate when needed
1440      - cost_bp_read.F : use arguments, instead of common blocs
1441        so that it can be used also by (new) cost_gencost_bpv4.F
1442      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1443      - ecco_phys.F : compute etanFull
1444      - ecco_readparms.F : rename using_topex as using_tpj, add
1445        bpv4-grace to gencost list, initialize added parameters
1446      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1447    
1448    checkpoint65e (2014/09/28)
1449    o pkg/obcs:
1450      - replaced the just-added CPP options with run-time variables
1451        (see pkg/obcs/OBCS_PARAMS.h for details)
1452    o pkg/obcs:
1453      - add additional CPP options for sponge boundary layers
1454        (see pkg/obcs/OBCS_OPTIONS.h for details)
1455    o pkg/atm_phys:
1456      - implement simple (obliquity only, assuming circular planet orbit)
1457        seasonal cycle for incoming insolation ; used when run-time parameter
1458        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1459    o pkg/exf, pkg/ecco, pkg/ctrl:
1460      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1461      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1462      - implement gentim2d for xx_tauu, xx_tauv
1463    o pkg/ctrl, pkg/ecco :
1464      - fix and complement the generic controls implementation
1465    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1466        pkg/shelfice/shelfice_thermodynamics.F,
1467        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1468        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1469      - add weight in CTRL_GET_GEN calls
1470    o pkg/ctrl :
1471      - ctrl_get_gen.F : add weight as input parameter, and apply
1472        it directly rather than using smooth_correl2Dw (to be retired).
1473      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1474    o pkg/ctrl :
1475      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1476        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1477      - re-activate ctrl_summary (call in ctrl_init.F)

1484      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1485    
1486    checkpoint65d (2014/09/15)
1487    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1488      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1489        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1490    o pkg/ctrl/ctrl_map_ini_genarr.F :
1491      - remove compilation failure
1492      - replace hard coded example
1493      - use ctrl_map_ini_gen2D, 3D
1494    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1495      - on/off switch based upon xx_genarr2d_weight,3d
1496    o src/packages_init_variables.F :

1511      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1512    o ecco/ecco_ad_diff.list :
1513      - add ecco_init_varia.f
1514    o ecco/ecco_init_varia.F
1515      - new routine
1516    o pkg/streamice:
1517      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1518        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1519      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1520    o pkg/generic_advdiff:
1521      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1522    o pkg/exf:
1523      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1524         xxg_precip capability
1525      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1526    o pkg/ctrl:
1527      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1528    o model/src/load_fields_driver.F :
1529      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1530        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1531    o OpenAD verification experiments:
1532      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1533        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1534        for now, only in pkgs used in OpenAD verification experiments.
1535      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1536        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1537        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1538        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1539    o OpenAD verification tests:
1540      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1541      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1542        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1543      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1544        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1545    o model/src & generic_advdiff:
1546      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1547        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1548        dynamics requires valid tracer forcing only over tile interior but, for
1549        some diagnostics, may need to extend it over 1 point in tile halo region.
1550      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1551        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1552        setting in temp/salt/ptracer_integrate.F
1553    o pkg/dic:
1554      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1555        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1556        in gchem_forcing_sep.F
1557    o pkg/autodiff & obcs:
1558      - add storage of current OB values for U & V (was already done for T & S).
1559    
1560    checkpoint65c (2014/08/30)
1561    o pkg/dic:
1562      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1563        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1564        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1565    o verification:
1566      - new experiment testing OBCS and DIC pkgs, using params & output from
1567        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1568        passage: take OBCS from the last year of a 2 yrs simulation and initial
1569        conditions from t=1.yr while keeping the same forcing.
1570    o model/src:
1571      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1572        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1573    o pkg/diagnostics (Stats-Diags):
1574      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1575        a) refine region where stats are computed, excluding where arrhFac=0 ;
1576        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1577        c) extend regional stats over the region edges (for U or V pt location).
1578    o pkg/gchem:
1579      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1580        pkg/dic is currently changing/updating ptracers values beyond the OB).
1581    o verification (hs94):
1582      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1583        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1584        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1585        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1586    o pkg/ptracers:
1587      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1588        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1589      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1590        with AB-2 code (so that it get tested).
1591    o model/src:
1592      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1593        with AB-2 code (previously only available with AB-3 code).
1594        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1595        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1596        there, by calling CYCLE_AB_TRACER).
1597    o pkg/generic_advdiff:
1598      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1599        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1600        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1601        S/R temp/salt/ptracers_integrate.F
1602    o model/src & pkg/ptracers:
1603      - remove common block variables gT,gS (in DYNVARS.h), except when
1604         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1605      - remove common block variable gPtr.
1606    o model/src & pkgs:
1607      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1608         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1609         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1610         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1611      + change accordingly all calling S/R.
1612      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1613        in S/R temp/salt/ptracers_integrate.F
1614    o pkg/seaice:
1615      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1616        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1617      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1618        in seaice_lsr
1619      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1620        in s/r seaice_lsr_calc_coeffs
1621    o pkg/mdsio:
1622      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1623        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1624        too long (e.g., > MAX_LEN_FNAM/2 )
1625    
1626    checkpoint65b (2014/08/12)
1627    o pkg/matrix:
1628      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1629    o model/src:
1630      - fix initialisation of geothermalFile; compile geothermal-flux code in
1631        natl_box verification experiment.
1632    o model/src & pkg/down_slope:
1633      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1634      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1635        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1636        results at machine truncation level: update output of experiments
1637        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1638    o pkg/diagnostics (Stats-Diags):
1639      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1640        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1641        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1642        times (but Min,Max and StD are still wrong).
1643    o model/src:
1644      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1645        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1646    o model/src:
1647      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1648        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1649        arrays are already updated while adjustments (filters, conv.adjustment) are
1650        still applied later, in S/R TRACERS_CORRECTION_STEP.
1651    o model/src:
1652      - store in common bloc array "rhoInSitu" the virtual potential temperature
1653        anomaly that is used to compute geopotential: this make the atmos code
1654        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1655    o pkg/seaice/seaice_lsr.F
1656      - rename integer variable ilcall to ipass (that's what it is called
1657        in the residual diagnostics
1658      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1659        default) for improved non-linear convergence of the first few steps
1660      - adjust a few comments and add new ones to explain some of the store
1661        directives
1662    o pkg/generic_advdiff (& ptracers):
1663      - re-work the code to check for valid advection scheme and for minimum
1664        size of overlap (now stored in local common bloc in gad_advscheme.F)
1665    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1666      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1667      - add an auxilliary variable "bet" and fix store directives and keys in
1668        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1669        less exact gradients in my tests); but there are still
1670        recomputation warning (although gradients are sort of OK), when
1671        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1672        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1673      - update verification experiments lab_sea.
1674      - change some comments in S/R seaice_calc_viscosities
1675    o model/src:
1676      - if staggerTimeStep=T, always apply exchange to velocity field in
1677        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1678        (independent of using multi-dim advection or not); no effect on FWD run
1679        but affects AD results (at machine truncation level): update output of
1680        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1681        and isomip (oad: 12.d).
1682    o pkg/generic_advdiff:
1683      - stop if doAB_onGtGs is set to FALSE but ignored
1684      - refine warning related to stability of tracer time-stepping
1685        regarding internal wave dynamics.
1686      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1687        on staggerTimeStep & implicitIntGravWave (will now get a warning
1688        if potentially unstable).
1689    o pkg/kl10:
1690      - add new pkg "kl10" for mixing due to internal wave breaking, from
1691        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1692        (contribution from Jody Klymak), tested in verification experiment
1693        verification/internal_wave/input.kl10/
1694    o isomip experiment:
1695      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1696        (input.htd) and update the output.
1697    o cd_code experiments:
1698      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1699        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1700        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1701        update the corresponding output.
1702    o pkg/seaice:
1703      - reduce the number of include files and store directives in
1704        S/R seaice_lsr_tridiagu/v
1705      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1706        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1707        get rid off one store directive (a TAF bug?)
1708      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1709        S/R seaice_lsr_tridiagv to change the loop range for consistency
1710      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1711      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1712        S/R seaice_lsr_tridiagu/v (requires update of
1713        offline_exf_seaice/input.dyn_jfnk)
1714    
1715    checkpoint65a (2014/07/27)
1716    o model/src:
1717      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1718        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1719        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1720        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1721    o model/src:
1722      - collect momentum forcing tendency into local 2-D array (passed as argument
1723        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1724        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1725        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1726      - collect T & S forcing tendency into local 2-D array (passed as argument to
1727        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1728        affects results at machine truncation level (e.g., ocean: if using
1729        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1730        correction due to vertical advection).
1731      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1732        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1733        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1734        obcs_ctrl (ad & fwd grd @ 12 & 7).
1735    o pkg/ptracers & diagnostics:
1736      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1737        title (to avoid some unexpected truncation); sort out ptracers diags units.
1738      - collect ptracer forcing tendency into local 2-D array (passed as argument
1739        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1740    
1741    checkpoint65 (2014/07/18)
1742    o pkg/fizhi:
1743      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1744        affects results at machine truncation level. Update output of experiments
1745        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1746    o pkg/seaice: more clean up
1747      - rename TAF common block tapes to be more consistent and remove
1748        unnecessary duplicates
1749      - add store directives to remove more recomputations, but use smaller
1750        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1751        The idea behind this flag is to reduce the memory footprint when the
1752        adjoint of the LSR is not required. As of now, defining the flag
1753        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1754        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1755        For experiment offline_exf_seaice, this means on a linux box with gfortran
1756        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1757        this experiment):
1758        > size mitgcmuv_ad
1759        text    data        bss     dec        hex
1760        5100659 1216  220458952  225560827  d71c8fb
1761        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1762        but only a moderate increase of 36% for global_ocean.cs32x15:
1763        text    data        bss     dec        hex
1764        6695027 1648 1014578664 1021275339 3cdf6ccb
1765        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1766      - note: there are still recomputations in global_ocean.cs32x15 and
1767        offline_exf_seaice and the gradient agreement changes (gets a
1768        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1769      - in general, the AD gradients still are wrong
1770    o OpenAD
1771      - clean up code_oad/ directories somewhat by moving files
1772        dontCompile, dontTransform, keepOriginal to OAD_support/
1773    o model/src:
1774      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1775        (not currently tested): add dissipation terms before NLFS rescaling of
1776        tendencies (previously done after).
1777    o pkg/diagnostics:
1778      - write stats-diags in ascii file with more digits (same as in monitor).
1779    o pkg/down_slope:
1780      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1781        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1782    o model/src:
1783      - new file "apply_forcing.F" containing all the code previously in
1784        external_forcing.F, but with new argument list: pass, as new argument,
1785        the current level tendency array to update (instead of a direct update
1786        of the common bloc array). Change the corresponding calls.
1787      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1788        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1789    o pkg/seaice/seaice_lsr, a little bit of clean up
1790      - rearrange some code blocks, so that now all calculations for
1791        setting up the right-hand-sides done within one single block
1792        (I find that easier to read and understand)
1793      - rearrange freedrift-code to reduce the number of ifdefs
1794      - adjust some indentations and comments
1795    
1796    checkpoint64z (2014/07/10)
1797    o model/src and several pkgs:
1798      - change argument list of all S/R called from external_forcing.F and
1799        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1800        to pass, as argument, the current level tendency array to update
1801        (instead of a direct update of the common bloc array).
1802      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1803      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1804    o pkg/seaice/seaice_lsr.F
1805      - always initialize local arrays in seaice_lsr_tridiagu/v
1806      - add more local tapes to seaice_lsr_tridiagu/v
1807      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1808        keep it in bi/bj loop; this seems to be essential
1809      - gradients are still wrong but only by 4-7 orders of magnitude
1810        instead of 15 orders of magnitude, lab_sea improves a little
1811    o pkg/seaice
1812      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1813        generates unnecessary code in seaice_lsr_ad
1814      - add more store directives in seaice_lsr to avoid unnecessary code
1815        in seaice_lsr_ad
1816      - exclude some residual computations in seaice_lsr when
1817        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1818        in seaice_lsr_ad
1819      - add more storing, a new tape (model/src/the_main_loop.F) and
1820        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1821        and klockey should be checked by a specialist)
1822      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1823        and update lab_sea after previous changes in pkg/seaice below
1824    o pkg/autodiff:
1825      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1826        viscFacInAd : run time parameters allowing for adjoint switches
1827        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1828    o pkg/ecco:
1829      - introduce cost_gencost_boxmean.F that computes a box mean
1830        temperature (for use in adjoint sensitivity studies).
1831    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1832    o pkg/mom_common/mom_calc_visc.F:
1833      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1834    o pkg/seaice/seaice_summary.F:
1835      - statement for SEAICEadjMODE now in autodiff_readparms.F
1836    o pkg/seaice:
1837      - remove some store directives and add new ones in an effort to get
1838        finally rid off the recomputation warnings. This is successful
1839        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1840        defined (i.e. no extensive recomputation warnings left), but there
1841        are still too many recomputations on the solver iteration level
1842      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1843      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1844        SEAICE_SIZE.h
1845      - add a store directive in S/R seaice_calc_viscosities
1846    o pkg/seaice (ITD code):
1847      - fix definition of Hlimit for multi-threaded case
1848      - use double precision arithmetic to compute Hlimit: this affects results;
1849        update output of experiment seaice_itd.
1850    o replace content of verification/seaice_itd
1851      - instead of a 1D column use the configuration of offline_exf_seaice
1852        to test the ice thickness distribution code with ridging
1853      - this is a first shot at this experiment
1854      - change of some defaults of ridging parameters SEAICEhStar (from
1855        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1856        and lot of new comments.
1857    
1858    checkpoint64y (2014/06/20)
1859    o pkg/seaice/seaice_reg_ridge.F:
1860      - modify the regularization of very small volumes of ice; only check
1861        total volume HEFF, and do not apply correction to individual ice
1862        classes because that leads to funny patterns in the heat and fw-fluxes
1863        into the ocean. Adjust seaice_itd/results/output.txt
1864      - replace nITD by SEAICE_multDim in loop-ranges
1865    o pkg/exf:
1866      - add code to process the case field period = -12. with UV interpolation.
1867      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1868        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1869    o verification/global_with_exf:
1870      - switch all fields period to -12. (was previously untested) in input/data.exf
1871        (but keep secondary test ".yearly" unchanged); update the reference output.
1872    o pkg/cal:
1873      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1874    o pkg/exf:
1875      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1876        to replace logical switch "exf_verbose"
1877      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1878    o pkg/sbo:
1879      - update from Katherine Quinn: evaluate mass directly from density and SSH
1880        (budget using Finite Volume method) instead of from bottom pressure.
1881      - allow testreport to collect few selected SBO output ; tested in exp.
1882        global_ocean.90x40x15 (after updating the results, to include SBO output).
1883      - fix some multi-threading issues (in output part).
1884    o model/src & most packages:
1885      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1886      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1887        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1888        "data.{pkg}" exist ; and leave the S/R (return) just after.
1889      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1890        + call LAND_READPARMS from packages_readparms.F
1891    o pkg/seaice:
1892      - remove code that resets useThSice in S/R seaice_readparms and
1893        replace it by a warning in S/R seaice_check
1894      - remove parameter MULTDIM, replace with nITD and runtime
1895        parameter SEAICE_multDim (still hard-wired to nITD if
1896        SEAICE_ITD is defined)
1897    
1898    checkpoint64x (2014/05/24)
1899    o verification/lab_sea:
1900      - update adjoint and TLM output following changes to pkg/salt_plume
1901      - un-do the update after putting back local recip_Cp in few places.
1902    o pkg/salt_plume: modifications by An Nguyen:
1903      - add capability to do brine rejection (salt-plume) as function of
1904        volume+tracers (instead of only salinity tracer).
1905      - conserve volume by exchanging volume from each kLev to above to
1906        accommodate in-coming brine volume
1907      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1908      - switch KPP surf buoyancy due to brine forcing to 3-d
1909        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1910      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1911      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1912        in East/West Arctic.
1913    o pkg/sbo:
1914      - incorporate modifications from Katherine Quinn to enable the use of sbo
1915        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1916        output for future testreport verification (unfinished).
1917    o pkg/atm_phys:
1918      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1919        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1920        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1921    o pkg/seaice
1922      seaice_calc_ice_strength.F: modify expression to avoid divisions
1923        (affects truncation)
1924      seaice_do_ridging.F: clean up the insectarium
1925      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1926      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1927      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1928      - add some debugging information and error messages (warnings)
1929    o model/src: modifications relatd to atmosphere p*:
1930      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1931      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1932        of vertical profile tRef in geopotential background and anomaly.
1933      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1934        and pkg/atm_phys.
1935      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1936        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1937    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1938    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1939        not used right now, but can be used in BGC packages to fix conservation.
1940    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1941        other packages too.
1942    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1943        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1944    o model/src:
1945      - since we have several heat capacity (even in model/src), define "recip_Cp"
1946        as local variable (no longer in common block) to avoid any confusion.
1947      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1948    o pkg/exf:
1949      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1950        air density as function of air Temp, Humidity and atm pressure.
1951    
1952    checkpoint64w (2014/05/02)
1953    o verification:
1954      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1955        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1956        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1957        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1958        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1959    o model/src: for atmosphere in p* coords:
1960      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1961      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1962        but not yet activated.
1963    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1964      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1965      - this changes the results (but not for any verification experiment, because
1966        none tests this), but avoids having an extra field in the restart files
1967    o pkg/seaice: remove global variable TICE (not needed)
1968      - replace by TICES or local variable where necessary (cost_seaice_test,
1969        seaice_diagnostics_state)
1970      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1971      - use specific read/write routines for reading and writing individual leves
1972        of a multilevel field
1973    o pkg/ctrl & model/inc:
1974      - move additional anomaly fields of control vars (related to options:
1975         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1976        from DYNVARS.h into new header file: CTRL_FIELDS.h
1977    o pkg/seaice: some small modifications to the ridging code
1978      - make fw2ObyRidge a global variable and add the freshwater flux to
1979        seaice_growth
1980      - pass actual thickness from seaice_prepare_ridging, so that it is
1981        computed only in one place and compute it in the same way as in
1982        seaice_growth
1983      - initialise more fields in seaice_do_ridging that where cause floating
1984        point exceptions over land
1985    o pkg/seaice: preparations for ridging code and first real ridging code
1986      - move most of "PART 1" of S/R seaice_growth into a new and separate
1987        S/R seaice_reg_ridge that will both regularize the state variable after
1988        advection call the actual ridging routine;
1989      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1990        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1991      - remove ridging code from seaice_advdiff
1992      - clean up remaining part 1 of seaice_growth in an attempt to make it
1993        more readable (this is probably subjective)
1994      - call seaice_itd_redist once in the initialisation phase to have the initial
1995        conditions in the correct category
1996      - finally: add new ridging routine for ITD code
1997    
1998    checkpoint64v (2014/04/11)
1999    o pkg/ecco:
2000      - add runtime parameters mdt[start,end]date[1,2]
2001      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
2002    o pkg/seaice:
2003      - make deltaC a global variable, so that it can be used in ridging code
2004      - first step towards ridging: introduce new routines that compute
2005        ice strength based on ridging parameters
2006      - add diagnostic for HSNOWITD
2007      - add opnWtrFrac as a global variable (required for ridging scheme)
2008    o pkg/salt_plume + pkg/seaice/seaice_growth.F
2009      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
2010        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
2011    o verification/hs94.1x64x5:
2012      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
2013      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
2014    o autodiff:
2015      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
2016        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
2017        For now, only in pkgs used in verification/hs94.1x64x5.
2018      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
2019        which are specific to TAF/TAMC).
2020      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
2021        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
2022        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
2023      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
2024        building mitgcmuv_ad (make adAll).
2025    o pkg/ecco:
2026      - cost_gencost_seaicev4.F:
2027         reformulate proxy cost as function of sst and local param SEAICE_freeze
2028         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
2029      - add stop statement if old names siv4-[sst,vol] are used
2030      - add snapshots + cost reports for atmospheric longwave
2031      - remove factor 0.1 in front of wtau[u,v]
2032      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
2033         ALLOW_TMI_SST_COST_CONTRIBUTION
2034    o pkg/atm_phys:
2035      - add some diagnostics for Short-wave and for convection S/R.
2036    o pkg/seaice/seaice_growth:
2037      - fix a bug in the lateral melt parameterization for SEAICE_ITD
2038        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
2039      - rearrange loop order for better vector code in the same code block
2040      - rewrite the floeDiameter formula to have fewer divisions
2041      -  (miraculously) none of this changes the results of seaice_itd
2042    o pkg/smooth:
2043      - move param smooth2Ddiffnbt to pkg/ecco
2044    o pkg/salt_plume:
2045      - salt_plume_frac.F:
2046         clean up local param names
2047         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
2048    o pkg/rw:
2049      - add RS version of S/R READ_MFLDS_LEV.
2050    o pkg/streamice:
2051      - fix the restart test by writing/reading pickup_streamice files.
2052    o pkg/seaice:
2053      - refine checks for jfnk-related parameters
2054      - comment out if statement with SEAICEuseIMEX parameter as long as there
2055        is no IMEX code to avoid confusion and surprises
2056    
2057    checkpoint64u (2014/03/07)
2058    o verification/MLAdjust:
2059      - rename secondary test suffix:
2060         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
2061         0.leithD -> AhFlxF  + switch to flux-form
2062         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
2063         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
2064    o pkg/mom_vecinv:
2065      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
2066        to be before mom_calc_visc.F)
2067      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
2068      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
2069        this is simpler for the adjoint and for diagnostics.
2070    o model/src + pkg/momentum:
2071      - add input files for  2-D additional Western and Southern cell-edge wall
2072         (e.g., to add "thin-wall" where it is =1).
2073      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
2074        using 2nd hFacZ that is computed from initial (fix domain) hFac
2075      - known limitations of thin wall implementation: not yet coded for sigma
2076        coords; not working with CD-scheme neither.
2077    o pkg/seaice:
2078      - rename recently introduced parameters from (wrong name) AB to
2079        BDF (backward difference time discretisation)
2080      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
2081    o tools/adjoint_options:
2082      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
2083    
2084    checkpoint64t (2014/02/01)
2085    o pkg/ecco
2086      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
2087        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
2088      - replace hard-coded record number and period which only work for monthly
2089        with read-in runtime param that works for other periods (month,day,year)
2090    o pkg/thsice
2091      - corrected store directive fixes thsice adjoint gradient checks
2092    o genmake2 & testreport:
2093      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
2094        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
2095        Update testreport accordingly. No need to set "export OPENAD=true"
2096        in adjoint_options/adjoint_oad anymore (will be removed later).
2097    o pkg/shelfice:
2098      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
2099        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
2100        so that surface forcing applies to k=kSurf if using pkg/shelfice.
2101    o pkg/ctrl, pkg/grdchk, pkg/ecco:
2102      - Changes to make GENARR more modular (i.e. invisible if not used)
2103    o model/src/temp_integrate.F and salt_integrate.F
2104      - re-include store directives that were removed on Dec 27th.
2105    o model/src/external_forcing_surf.F
2106      - add storage directives for EmPmR and PmEpR to avoid recomputation of
2107        seaice_model in the adjoint that is problematic when seaice_model is
2108        turned off in the adjoint. The resolved issue dated back to July when
2109        EXTERNAL_FORCING_SURF call was moved.
2110        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
2111    o pkg/exf/exf_check.F
2112      - fix a small bug again (originally found by Wentao Liu, now found again)
2113      - streamline error output
2114    o pkg/streamice and aim_v23:
2115      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
2116        Apple's /usr/bin/cpp knows what to do:
2117        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
2118        Target: x86_64-apple-darwin13.0.0
2119    
2120    checkpoint64s (2014/01/05)
2121    o tools/adjoint_options:
2122      - switch to fastopt.net TAF server (instead of default fastopt.de) for
2123        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
2124    o model/src:
2125      - remove some unnecessary TAF storage directives in forward_step.F and
2126        in dynamics.F (note: not always removed by TAF, e.g., double storage
2127        of kappaRU,kappaRV in former version of dynamics.F).
2128    o model/src & pkg/ptracers:
2129      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
2130        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
2131        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
2132      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
2133      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
2134      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
2135    o useSingleCpuInput separates single-CPU input from single-CPU output;
2136        for now only implemented for in exf_interp_read.F
2137    o verification/advect_xy:
2138      - fix missing EXCH call in local version of ini_salt.F and update output.
2139    o momentum diagnostics:
2140      - fix which deltaT is used in Total-Tendency diagnostics.
2141      - fix typo in diagnostics for momentum tendency from AB.
2142    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
2143        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
2144    
2145    checkpoint64r (2013/12/08)
2146    o verification/*/results:
2147      - Update reference output of experiments that were passing with just 13 digits
2148         (make it easier to detect future changes in results)
2149    o model/src & pkg/ptracers:
2150      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
2151        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
2152        to inside ptracers_integrate.F ; remove ptracers_advection.F
2153    o coupling interface pkgs:
2154        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
2155      - change the config check to test the agreement of Ocean Depth
2156        with ATM land/sea mask (instead of ATM orography);
2157      - send to coupler the number of coupler time-steps to do for this run:
2158        this allows to check for consistency and don't need anymore to be
2159        specified in parameter file "data";
2160      in coupler:
2161      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
2162      - improve report to log-file of config setting (pass log-file unit to few S/R)
2163    o pkg/compon_communic:
2164      - add coupling send/receive for non-tiled integer vector;
2165      - add S/R to check and stop if any proc has an error (similar to
2166        eesupp/src/stop_if_error.F but single thread and across Comm_World).
2167    o pkg/exch2:
2168      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
2169        through list of all tiles my proc owns.
2170    o model/src:
2171      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
2172        from rTrans) to simplify dependencies (no need to store rTrans anymore in
2173        calling S/R); this affects AD results at machine truncation level:
2174        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
2175        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
2176    o tools/build_options:
2177      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
2178    o coupling interface pkgs:
2179        [compon_communic, atm_compon_interf & ocn_compon_interf]
2180      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
2181        to each S/R that needs it; remove un-used variables.
2182      - change component tile registration (cpl_register.F in both compon_interf
2183        and mitcomponent_tile_register.F) to pass the full list of tiles
2184        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
2185      - with pkg/exch2: adopt the same convention used for I/O to define mapping
2186        towards coupler global array (unless W2_useE2ioLayOut=F):
2187         a) can now use different tiling between atm & ocn comp.
2188         b) no needs to modify the run-Off map when changing tiling (was needed
2189            even if using the same tiling between atm & ocn).
2190         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
2191            full land tiles); not yet tested.
2192      - check for valid mapping from comp. tile to coupler global array
2193      - improve report of tile registration results to log file.
2194    o pkg/exch2:
2195      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
2196        tile-registration (CPL_REGISTER);
2197      - activate (un-comment) definition and setting of "W2_tileIndex" list to
2198        store the local bi,bj indices of each tile;
2199      - also print bi,bj in local report to log file;
2200      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
2201        Jun 2009 modif of pkg/exch2).
2202    o testing on baudelaire:
2203      - run 2 tests at a time: no significant slow down (since enough cpu) and
2204        get the full set of test done earlier
2205      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
2206    o model/src/thermodynamics.F and routines called from it:
2207      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
2208        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
2209        velocity (outp) by adding bolus velocity.
2210      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
2211        mass transport from velocity + lateral grid cell area
2212      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
2213      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
2214     in thermodynamics.F
2215      - remove k from thermodynamics.F and move it to temp_integrate.F
2216        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
2217        loop).
2218      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
2219        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
2220        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
2221        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
2222      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
2223        global_ocean.90x40x15, tutorial_global_oce_biogeo and
2224        tutorial_tracer_adjsens (+ TLM output).
2225    o tools/OAD_support and (verification/*/) code_oad:
2226      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
2227        module conversion ; remove unneeded CPP_EEOPTIONS.h.
2228      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
2229        version (closer to model/inc/CPP_OPTIONS.h).
2230    o model/src:
2231      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
2232        retired list of parameters (routine FREEZE has been replace by surface
2233        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
2234    o pkg/gmredi:
2235      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
2236        velocity (same scheme but affects machine truncation) for GM_AdvForm.
2237      - update output of FWD experiments: front_relax.bvp,
2238        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
2239    
2240    checkpoint64q (2013/11/17)
2241    o verification:
2242      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
2243        tutorial_global_oce_biogeo and global_ocean.90x40x15.
2244      - generate new output (growth & melt) for seaice_itd experiment after
2245        updating the input pickup_seaice files (previously wrong).
2246    o pkg/cost:
2247      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
2248        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
2249        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
2250          cannot be applied to var in common block).
2251        o allows to get results independent of tile-per-proc setting (if using
2252          slower GLOBAL_SUM_SEND_RECV option).
2253      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
2254        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
2255        forward gradients: update output).
2256      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
2257        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
2258    o pkg/mom_common:
2259      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
2260        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
2261        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
2262        ensure that all field value that are used are set.
2263    o tutorial_deep_convection (smag3d):
2264      - add missing scaling in mom_calc_smag_3d.F;
2265      - set smag3D_coeff in input.smag3d such that results do not change.
2266    o pkg/dic:
2267      - change dic_cost.F to compute cost on each tile first and then apply
2268        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
2269        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
2270      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
2271    o eesupp/src & pkg/mdsio:
2272      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
2273        (from pkg/mdsio) since they are no longer used for tape IO.
2274      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
2275        (+ keep a copy in pkg/atm_ocn_coupler).
2276    o verification/isomip:
2277      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
2278    o tools/build_options:
2279      - optfile linux_amd64_ifort11, fast (no ieee) case:
2280        to get a working restart for all experiments, add "-fp-model source"
2281        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
2282    
2283    checkpoint64p (2013/10/20)
2284    o pkg/autodiff:
2285      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
2286        criteria, return to simple (default) tape IO format.
2287    o pkg/mdsio (+ eesupp/src):
2288      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
2289        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
2290      - fix globalFile and singleCpuIO options using simpler global mapping.
2291      - new pairs of scatter/gather vector S/R (one for each type, generated from
2292        template) corresponding to simpler global mapping.
2293      - adread_write.F: switch to new S/R (but leave old calls commented) and write
2294        to globalFile when parameter globalFiles is set to True.
2295      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
2296    o pkg/autodiff:
2297      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
2298        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
2299        missing, just add a STOP if array type do not match.
2300    o pkg/exf:
2301      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
2302         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
2303         and rename array obsSIce to exf_iceFraction.
2304    o tutorial_deep_convection:
2305      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
2306        for now all in this exp. code dir.
2307      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
2308        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
2309    o eesupp/src:
2310      - added SINGLE_DISK_IO option because reading of parameter files on
2311        very large number of processors did not work with existing set-up
2312    
2313    checkpoint64o (2013/09/25)
2314    o pkg/atm_phys & atm_compon_interf:
2315      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
2316    o tools/build_options:
2317      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
2318        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
2319        remove CPP setting (was identical to genmake2 default).
2320    o pkg/gmredi & model/src: Some updating and work done on the residual model.
2321      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
2322      - fixed up the calculation of the eddy stress and how it is added to the
2323        external forcing via taueddy_external_forcing.F
2324      - at the moment, it is very experimental and only works with the variable eddy
2325        diffusivity calculated in gmredi_k3d.F
2326    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
2327        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
2328    o testreport (& tools/do_tst_2+2):
2329      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
2330    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
2331      - remove CPP='cpp -traditional -P' (this is genmake2 default)
2332      - add switch (for big setups) to use 'medium' memory-model (but leave it
2333        commented out for now). Note: needed with FC 19 to compile big setups.
2334    o pkg/atm_compon_interf:
2335      - regroup per field origin (model & pkgs) the coupling storage routines
2336         (which accumalate in time each coupling field)
2337      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
2338        update accordingly + simplify aim_do_physics.F
2339    
2340    checkpoint64n (2013/08/26)
2341    o pkg/bbl:
2342      - update formulation to reduce dispersion of tracer properties in bbl
2343      - replaced horizontal and vertical transport parameters with velocities
2344      - changes results for verification/global_with_exf.yearly
2345    o verification/halfpipe_streamice:
2346      - change to matrix construction; update both Fwd & AD output.
2347    o verification/tutorial_tracer_adjsens:
2348      - OpenAD test: switch to vector-invariant momentum since fluxform with
2349        rStar causes problems with OpenAD; update output.
2350    o tools:
2351      - genmake2: define a common prefix for all temp-file names ; move them
2352        to local /tmp disk (but would be easy to move them back);
2353      - xmakedepend: apply the same switch for temp-files.
2354    o pkg/offline:
2355      - changes for use with rStar (NLFS): assume that we continue to provide
2356        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
2357        output files) and apply r* scaling at each time-step (function of the time
2358        varying Eta field); use normal pickup files (needed for restart with NLFS).
2359    o adjoint with OpenAD:
2360      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
2361        package openad.  This package has to be compiled for all runs with OpenAD
2362        instead of specifying code_oad_all as a modification directory.
2363      - link the fortran templates from tools/OAD_support to the build directory
2364        for preprocessing to avoid conflicts between different setups compiled
2365        simultaneously and simplify cleanup.
2366    o pkg/exf:
2367      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
2368        main model or other pkgs are exchanged in EXF_MAPFIELDS).
2369    o model/src:
2370      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
2371        (similar to do_fields_blocking_exchanges.F).
2372    o tools/genmake2:
2373      - remove TAF output src code just before calling staf (when not doing a fresh
2374        built, will stop if things go wrong with staf).
2375      - fix target "adobj" (left from TAF version-2 transition)
2376    o pkg/diagnostics:
2377      - add a parameter to track the status of pkg/diagnostics activation;
2378        this replace/extend the use of logical param "settingDiags" (to check
2379        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
2380        New S/R to print error message and stop when pkgStatus is not right.
2381      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
2382    
2383    checkpoint64m (2013/08/13)
2384    o model/inc:
2385      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
2386        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
2387    o pkg/kpp & aim_v23:
2388      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2389    o pkg/seaice:
2390      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
2391        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
2392      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2393    o eesupp/src:
2394      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
2395        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
2396    o switch to TAF version-2:
2397      - add flow directives to "freeze" naming convention for ad-routines that
2398        are used in I/O routines of adjoint state and associated common blocks
2399        that are used in adcommon.h (backward compatible with version-1)
2400      - update all ad-optfiles (in tools/adjoint_options + few local to some
2401        verification exp) to switch to latest TAF version (currently 2.5.5);
2402        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
2403        out except for diva).
2404      - the major change with TAF version-2 is that both the differentiated
2405        routines and the forward routines (new) are returned as part of the TAF
2406        output source code. Update genmake2 accordingly.
2407      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
2408        with version-2 when compared to TLM or FWD gradient); other experiments
2409        output show minor changes (machine truncation level); update the few AD &
2410        TLM output with 12 matching digits only (some prior to version-2 switch).
2411    
2412    checkpoint64l (2013/08/05)
2413    o model/src:
2414      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
2415      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
2416        when using TAF but only if using OpenAD.
2417    o pkg/mom_common+fluxform+vecinv:
2418      - always set horiz. viscosity arrays to background value before calling
2419        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
2420        only when using variable horiz. viscosity (useVariableVisc=T);
2421      - simplify mom_vecinv.F (only 1 block for momViscosity).
2422    o pkg/mom_common: variable horiz. viscosity in NH code
2423      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
2424        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
2425      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
2426        useBiharmonicVisc & useVariableVisc.
2427      - fix old bug (already in 1rst implementation of variable horizontal viscosity
2428        in calc_gw.F, version 1.27, 2006/06/20):
2429        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
2430        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
2431      - change background horiz viscosity in vertical momentum (gW) to always be
2432        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
2433        any type of variable viscosity, e.g., viscAh/4Grid)
2434      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
2435        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
2436        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
2437        default viscAh,viscA4 is zero).
2438    o model/src:
2439      - extend length of drC & recip_drC from Nr to Nr+1.
2440    o Divided Adjoint (DIVA) with MPI:
2441      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
2442      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
2443        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
2444    
2445    checkpoint64k (2013/07/23)
2446    o tools/OAD_support:
2447      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
2448        and remove it from genmake2.
2449    o tools/build_options:
2450      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
2451        MPI_HEADER_FILES list (let genmake2 find the missing headers)
2452    o verification/halfpipe_streamice:
2453      - change to driving stress formulation; update both Fwd & AD output.
2454    o tools/genmake2 and Divided Adjoint with MPI:
2455      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
2456      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
2457      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
2458        Makefile, which is set by genmake2, and check which mpi-headers are needed.
2459        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
2460      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
2461    o testreport:
2462      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
2463        perform additional runs (number of additional runs is "add_DIVA_runs" taken
2464        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
2465    o verification/lab_sea (AD test):
2466      - change to test Divided Adjoint Run in this set-up (both standard AD test
2467        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
2468    o pkg atm_ & ocn_compon_interf:
2469      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
2470        staggerTimeStep implementation) and disable (retired) corresponding
2471        parameter.
2472    o pkg/offline:
2473      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
2474      - add S/R OFFLINE_CHECK to print offline parameter summary
2475        and stop if loading a file that is not used;
2476      - enable to calculate GMRedi tensor, KPP mixing and convective index
2477        when the corresponding file(s) is/are not specified (but pkg is used).
2478      - comment out resetting of monitorFreq (to endTime) since it still useful
2479        for monitoring CFL numbers and checking offline fields.
2480    o OpenAD:
2481      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
2482        smaller standard output) and generate new (smaller) output (on baudelaire
2483        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
2484    o model/src:
2485      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
2486        (where external_forcing_adjust was called) and change list of arguments;
2487      - merge external_forcing_adjust.F into external_forcing_surf.F
2488      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
2489        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
2490        previously in file "balance_relax.F", now removed); remove corresponding
2491        arrays in FFIELDS.h.
2492      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
2493        a hack for getting back surfaceForcingS (loaded from file) when using
2494        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
2495      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
2496        (was getting only 11 digits for AD-grad, due to different truncation
2497         error in AD code).
2498    
2499    checkpoint64j (2013/07/04)
2500    o pkg/offline:
2501      - to enable the use of other features with pkg offline (e.g., obcs),
2502        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
2503      - comment out "allowFreezing" (now active) in 2 offline testing exp.
2504    o pkg/exf ALLOW_RUNOFTEMP
2505      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
2506      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
2507      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
2508    o pkg/atm_phys:
2509      - allows to add some damping on uVel,vVel (strength only function of k).
2510    o verification, ad-tests:
2511      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
2512        global_ocean_ebm and offline_exf_seaice.thsice.
2513    o verification/halfpipe_streamice:
2514      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
2515        flux input boundary conditions to be ignored; a fix for this bug changed
2516        verification results for forward test.
2517      - add adjoint test.
2518    o pkg/ptracers:
2519      - allow to restart without SOM pickup (resetting SOM to zero).
2520    o pkg/gmredi:
2521      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
2522      - It uses mixing length theory and suppression by steering level effects to
2523        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
2524        to JPO, for more details).
2525      - It also uses the diffusivity to calculate an eddy induced streamfunction
2526        based on a PV closure (rather than a buoyancy closure as in GM).
2527      - New files added to pkg/gmredi:
2528        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
2529          induced overturning streamfunction (called from gmredi_calc_tensor)
2530        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
2531          for use in gmredi_k3d
2532        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
2533          the eddy diffusivity
