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

1104        including ecco_zero, ecco_cp, ecco_cprsrl, ecco_diffmsk,
1105        ecco_addcost, ecco_add, ecco_div, ecco_readbar.
1106      - cost_gencal.F (new) : determine filnames and records.
1107      - cost_genread.F, cost_generic.F : condense code using ecco_toolbox.
1108      - cost_generic.F : use spzeroloc rather than hard-coded -9999,
1109        and exploit the above functions leading to more compact code.
1110      - cost_genread.F : rm un-necessary arguments, re-arrange args order.
1111      - ecco_check.F, ecco_readparms.F : bring logic up to date (using_tpj,
1112        using_ers, using_gfo, using_mdt is now only defined within gencost)
1113    o pkg/ecco: extend generic cost capabilities
1114      - pkg/ecco : added 3D gencost (ALLOW_GENCOST3D), added gencost
1115        capabilities via gencost_preproc (+ _c,_i,_r related params),
1116        gencost_posproc (+ _c,_i,_r related params), gencost_nrecperiod,
1117        gencost_outputlevel arguments to cost_generic
1118      - pkg/ecco/cost_genread.F (new) : interface between cost_generic
1119        and active_read, making room for gencost_preproc to take effect.
1120        Added preproc code ('climmon') to replace GENERIC_BAR_MONTH.
1121      - pkg/ecco/cost_generic.F :
1122        compute and store misfit maks*(model-data) in localdif that is
1123        then used in cost and for output, output misfit if outlev.GT.0
1124      - pkg/ecco/cost_averagesfields.F : depend on gencost_barskip
1125        rather gencost_barfile for deciding whether to write barfile
1126      - pkg/ecco/ecco_cost_driver.F : extract call to cost_profiles from cost_hyd
1127      - pkg/ecco/ecco_cost_init_fixed.F : extract gencost weights from
1128        ecco_cost_weights, re-activate ecco_summary, determine gencost_barskip
1129      - pkg/ecco/ecco_summary.F : report gencost variables
1130      - pkg/ecco/cost_gencost_customize.F : treat case of scatterometer costs
1131    o pkg/sea/SEAICE_OPTIONS.h : add ALLOW_COST_ICE, ALLOW_SEAICE_COST_SMR_AREA
1132    o pkg/ecco: internal re-organization
1133      - resolve un-necessary dependancies within pkg/ecco and to pkg/ctrl
1134        (rm includes of optim.h and ctrl.h, replace optimcycle with eccoiter,
1135        mv relevant variables definition from ecco_cost.h to ecco.h,
1136        make sure gencost routines only include ecco.h)
1137      - throughout : add missing CCP switches, rm unused variables,
1138        and rm un-necessary CPP switches
1139      - throughout gencost routines : replace modelstartdate with
1140        gencost_startdate when needed
1141      - cost_bp_read.F : use arguments, instead of common blocs
1142        so that it can be used also by (new) cost_gencost_bpv4.F
1143      - ecco_init_varia.F : initialize RHOsumGlob_0, VOLsumGlob_0
1144      - ecco_phys.F : compute etanFull
1145      - ecco_readparms.F : rename using_topex as using_tpj, add
1146        bpv4-grace to gencost list, initialize added parameters
1147      - ecco_summary.F : include SIZE.h needed for augmented ecco.h
1148    
1149    checkpoint65e (2014/09/28)
1150    o pkg/obcs:
1151      - replaced the just-added CPP options with run-time variables
1152        (see pkg/obcs/OBCS_PARAMS.h for details)
1153    o pkg/obcs:
1154      - add additional CPP options for sponge boundary layers
1155        (see pkg/obcs/OBCS_OPTIONS.h for details)
1156    o pkg/atm_phys:
1157      - implement simple (obliquity only, assuming circular planet orbit)
1158        seasonal cycle for incoming insolation ; used when run-time parameter
1159        "select_incSW" is set to 1 ; by default (=0), uses old unchanged formula.
1160    o pkg/exf, pkg/ecco, pkg/ctrl:
1161      - add ctrlUseGen and .NOT.ctrlUseGen exclusive brackets
1162      - activate gentim2d for xx_atemp,xx_aqh,xx_swdown,xx_lwdown,xx_precip
1163      - implement gentim2d for xx_tauu, xx_tauv
1164    o pkg/ctrl, pkg/ecco :
1165      - fix and complement the generic controls implementation
1166    o pkg/exf/exf_getclim.F, exf_getffields.F, exf_getsurfacefluxes.F,
1167        pkg/shelfice/shelfice_thermodynamics.F,
1168        verification/hs94.1x64x5/code_ad/ctrl_map_gentim2d.F,
1169        verification/hs94.1x64x5/code_oad/ctrl_map_gentim2d.F :
1170      - add weight in CTRL_GET_GEN calls
1171    o pkg/ctrl :
1172      - ctrl_get_gen.F : add weight as input parameter, and apply
1173        it directly rather than using smooth_correl2Dw (to be retired).
1174      - ctrl_map_gentim2d.F : add wgentim2d in CTRL_GET_GEN call
1175    o pkg/ctrl :
1176      - introduce run time switch ctrlUseGen (in ctrl.h, ctrl_check.F,
1177        ctrl_init_variables.F, ctrl_readparms.F, ctrl_summary.F)
1178      - re-activate ctrl_summary (call in ctrl_init.F)
1179    o pkg/ctrl/ctrl_cost_gen.F :
1180      - fix CCP brackets, remove un-necessary myiter, mytime

1185      - add ctrl_cost_gen2d.F (replaces pkg/ecco/cost_forcing_gen.F)
1186    
1187    checkpoint65d (2014/09/15)
1188    o pkg/ctrl/CTRL_GENARR.h, ctrl_readparms.F :
1189      - add xx_genarr2d_bounds,xx_genarr3d_bounds,
1190        xx_genarr2d_numsmooth, xx_genarr3d_numsmooth
1191    o pkg/ctrl/ctrl_map_ini_genarr.F :
1192      - remove compilation failure
1193      - replace hard coded example
1194      - use ctrl_map_ini_gen2D, 3D
1195    o pkg/ctrl/ctrl_pack.F, ctrl_unpack.F :
1196      - on/off switch based upon xx_genarr2d_weight,3d
1197    o src/packages_init_variables.F :
1198      - regroup pkg/estimation calls
1199      - remove CTRL_MAP_INI, CTRL_MAP_INI_ECCO
1200        (moved to ctrl_init_variables)

1212      - remove seaice_ctrl_map_ini (mv to ctrl_init_variables)
1213    o ecco/ecco_ad_diff.list :
1214      - add ecco_init_varia.f
1215    o ecco/ecco_init_varia.F
1216      - new routine
1217    o pkg/streamice:
1218      - move call to STREAMICE_INITIALIZE_PETSC from the_model_main.F
1219        to streamice_init_fixed.F ; fix setting of STREAMICEisOn.
1220      - from model/src, only call pkg/streamice routines if useStreamIce is TRUE.
1221    o pkg/generic_advdiff:
1222      - fix bug causing negatives in GAD_SMOLARKIEWICZ_HACK, introduced 8/8/2014.
1223    o pkg/exf:
1224      - exf_getffields.F : add xxg_atemp, xxg_aqh, xxg_swdown, xxg_lwdown,
1225         xxg_precip capability
1226      - exf_wind.F : no need for ALLOW_WSPEED_CONTROL cpp switch
1227    o pkg/ctrl:
1228      - ctrl_pack.F, ctrl_unpack.F : omit (un)packing of undefined xx_gentim2d
1229    o model/src/load_fields_driver.F :
1230      - move call to CTRL_MAP_GENTIM2D ahead of BULKF_FIELDS_LOAD, EXF_GETFORCING
1231        so xx_gentim2d can be applied to e.g. exf fields in a timely manner.
1232    o OpenAD verification experiments:
1233      - Include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h, and CTRL_OPTIONS.h
1234        in src files (to enable to skip the ECCO_CPPOPTIONS.h);
1235        for now, only in pkgs used in OpenAD verification experiments.
1236      - Change all except one (halfpipe_streamice) OpenAD experiments to use pkg
1237        specific option file (AUTODIFF_OPTIONS.h, COST_OPTIONS.h & CTRL_OPTIONS.h)
1238        instead of using ECCO_CPPOPTIONS.h (with all relevant options in it).
1239        This applies to both TAF (*/code_ad/) and OpenAD (*/code_oad/) tests.
1240    o OpenAD verification tests:
1241      - finish removing ALLOW_AUTODIFF_OPENAD (replaced by ALLOW_OPENAD);
1242      - finish replacing ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for
1243        tape/storage which are specific to TAF/TAMC) in pkgs used in OpenAD exp.
1244      - leave ALLOW_AUTODIFF_TAMC undef in OpenAD verification tests (*/code_oad/)
1245        and remove local copy of "tamc.h" (needed only if ALLOW_AUTODIFF_TAMC).
1246    o model/src & generic_advdiff:
1247      - change hard-coded loop-range in S/R APPLY_FORCING_T/S to set T & S
1248        forcing over 0:sNx+1, 0:sNy=1 (instead of just 1:sNx,1:sNy): Model
1249        dynamics requires valid tracer forcing only over tile interior but, for
1250        some diagnostics, may need to extend it over 1 point in tile halo region.
1251      - in gad_calc_rhs.F, update calls to gmredi_x/ytransport to get valid
1252        tendency over i,j_Min,Max range. This allows to simplfy i,j_Min,Max
1253        setting in temp/salt/ptracer_integrate.F
1254    o pkg/dic:
1255      - multiply tracer tendencies by maskInC (if ussing OBCS) before updating
1256        gchem tracers: this allows to skip the 2nd call to OBCS_APPLY_PTRACER
1257        in gchem_forcing_sep.F
1258    o pkg/autodiff & obcs:
1259      - add storage of current OB values for U & V (was already done for T & S).
1260    
1261    checkpoint65c (2014/08/30)
1262    o pkg/dic:
1263      - take out of dic_atmos.F the initialisation part (corresponding to istate=0)
1264        and move it to new S/R DIC_INI_ATMOS ; also simplify the dependencies for
1265        AD compilers (but still a Pb with multi-threading and Ajoint dependencies).
1266    o verification:
1267      - new experiment testing OBCS and DIC pkgs, using params & output from
1268        tutorial_global_oce_biogeo but limited to a sub-domain around Drake
1269        passage: take OBCS from the last year of a 2 yrs simulation and initial
1270        conditions from t=1.yr while keeping the same forcing.
1271    o model/src:
1272      - when allowFreezing=T, only reset below freezing initial Temp to Tfreezing
1273        (at any k) if checkIniTemp is not set to FALSE (default checkIniTemp=T).
1274    o pkg/diagnostics (Stats-Diags):
1275      - re-write S/R DIAGSTATS_CALC (more similar to TARGET_NEC_SX part) to:
1276        a) refine region where stats are computed, excluding where arrhFac=0 ;
1277        b) fix missing interior mask (use with OBCS) in 3-D fields statistics;
1278        c) extend regional stats over the region edges (for U or V pt location).
1279    o pkg/gchem:
1280      - add a (2nd) call to OBCS_APPLY_PTRACER in gchem_forcing_sep.F (needed since
1281        pkg/dic is currently changing/updating ptracers values beyond the OB).
1282    o verification (hs94):
1283      - convert Held & Suarez external_forcing.F (from hs94.cs, with Sigma-coords
1284        bits) to apply_forcing.F and undef USE_OLD_EXTERNAL_FORCING in experiments
1285        hs94.cs-32x32x5 and tutorial_held_suarez_cs ; also use the same version of
1286        apply_forcing.F in 2D hs94 (fwd, ad & oad) but keep LatLon hs94 unchanged.
1287    o pkg/ptracers:
1288      - implement Adams-Bashforth on pTracers (instead of on tracer tendency),
1289        switched on by setting PTRACERS_doAB_onGpTr=F (default set to doAB_onGtGs)
1290      - change exp4 secondary test (input.nlfs) to test AB on T & S & pTracer
1291        with AB-2 code (so that it get tested).
1292    o model/src:
1293      - allow to apply Adams-Bashforth on Temp & Salt (instead of on gT,gS)
1294        with AB-2 code (previously only available with AB-3 code).
1295        Also move the code (call to ADAMS_BASHFORTH S/R) form thermodynamics.F
1296        to temp/salt_integrate.F (since the 2nd part of gt/sNm1 update is done
1297        there, by calling CYCLE_AB_TRACER).
1298    o pkg/generic_advdiff:
1299      - change Tracer argument (drop bi,bj indices) in S/R GAD_CALC_RHS,
1300        GAD_C2_ADV_R, GAD_U3_ADV_R, GAD_C4_ADV_R, GAD_DIFF_R, GAD_BIHARM_R
1301        + also in GMREDI_X/Y/RTRANSPORT ; and update corresponding calls in
1302        S/R temp/salt/ptracers_integrate.F
1303    o model/src & pkg/ptracers:
1304      - remove common block variables gT,gS (in DYNVARS.h), except when
1305         USE_OLD_EXTERNAL_FORCING is defined; update TAF storage accordingly.
1306      - remove common block variable gPtr.
1307    o model/src & pkgs:
1308      - change gTracer (and/or tracer) argument (drop bi,bj indices) in S/R
1309         ADAMS_BASHFORTH(2&3), CYCLE_(AB_)TRACER, FREESURF_RESCALE_G,
1310         IMPLDIFF, SOLVE_TRIDIAGONAL & _PENTADIAGONAL, GAD_SOM_ADVECT,
1311         GAD_ADVECTION, GAD_CALC_RHS, GAD_IMPLICIT_R, TIMEAVE_CUMUL_DIF_1T
1312      + change accordingly all calling S/R.
1313      - use local temperature/salinity/ptracer tendency array (without bi,bj)
1314        in S/R temp/salt/ptracers_integrate.F
1315    o pkg/seaice:
1316      - move computation of stress contributions to rhsU/V in s/r seaice_lsr
1317        to separate s/r seaice_lsr_rhsu/v in order to be able to re-use code
1318      - make u/vIceC local variables if SEAICE_CGRID is defined only to be used
1319        in seaice_lsr
1320      - seaice_lsr.F: make local 4D arrays UXX, VYY, etc 2D
1321        in s/r seaice_lsr_calc_coeffs
1322    o pkg/mdsio:
1323      - in MDS_READ/WRITE_FIELD, stop if file-name (+prefix) is too long
1324        (e.g., > MAX_LEN_MBUF -90 ) or, in INI_MODEL_IO, if mdsioLocalDir is
1325        too long (e.g., > MAX_LEN_FNAM/2 )
1326    
1327    checkpoint65b (2014/08/12)
1328    o pkg/matrix:
1329      - pass, as argument, updated tracer field to S/R MATRIX_STORE_TENDENCY_EXP
1330    o model/src:
1331      - fix initialisation of geothermalFile; compile geothermal-flux code in
1332        natl_box verification experiment.
1333    o model/src & pkg/down_slope:
1334      - push the k loop inside S/R TIMESTEP_TRACER (now called outside the k loop).
1335      - in dwnslp_apply.F, update tracer tendency instead of the future tracer
1336        field and call S/R DWNSLP_APPLY before TIMESTEP_TRACER; this affects
1337        results at machine truncation level: update output of experiments
1338        global_ocean.90x40x15.dwnslp (FWD) and lab_sea.noseaicedyn (AD).
1339    o pkg/diagnostics (Stats-Diags):
1340      - do not cumulate the full volume when DIAGNOSTICS_FILL is
1341        called with bibjFlg < 0 (no increment of the counter for 2D/3D diag);
1342        This fix the mean statistics when DIAGNOSTICS_FILL is called multiple
1343        times (but Min,Max and StD are still wrong).
1344    o model/src:
1345      - add geothermal flux forcing: read in ini_forcing.F as time-constant
1346        field "geothermalFlux" applied in S/R APPLY_FORCING_T (apply_forcing.F)
1347    o model/src:
1348      - move CYCLE_TRACER calls from tracers_correction_step.F to temp/salt/ptracer
1349        _integrate.F so that, when leaving S/R THERMODYANMICS, theta,salt and pTrac
1350        arrays are already updated while adjustments (filters, conv.adjustment) are
1351        still applied later, in S/R TRACERS_CORRECTION_STEP.
1352    o model/src:
1353      - store in common bloc array "rhoInSitu" the virtual potential temperature
1354        anomaly that is used to compute geopotential: this make the atmos code
1355        more similar to ocean code which already uses rhoInSitu in calc_phi_hyd.F
1356    o pkg/seaice/seaice_lsr.F
1357      - rename integer variable ilcall to ipass (that's what it is called
1358        in the residual diagnostics
1359      - change time stepping for NPSEUDOTIMESTEP > 2 (does not change the
1360        default) for improved non-linear convergence of the first few steps
1361      - adjust a few comments and add new ones to explain some of the store
1362        directives
1363    o pkg/generic_advdiff (& ptracers):
1364      - re-work the code to check for valid advection scheme and for minimum
1365        size of overlap (now stored in local common bloc in gad_advscheme.F)
1366    o pkg/seaice: another attempt to make the adjoint work for sea ice dynamics
1367      - re-initialize more variables in seaice_lsr: u/vIceC, u/vIceNm1
1368      - add an auxilliary variable "bet" and fix store directives and keys in
1369        seaice_lsr_tridiagu/v, this seems to do the trick (i.e. more or
1370        less exact gradients in my tests); but there are still
1371        recomputation warning (although gradients are sort of OK), when
1372        SEAICE_LSR_VECTORIZE is not defined, so this flag and
1373        SEAICE_LSR_VECTORIZE_ZEBRA are recommended for efficiency.
1374      - update verification experiments lab_sea.
1375      - change some comments in S/R seaice_calc_viscosities
1376    o model/src:
1377      - if staggerTimeStep=T, always apply exchange to velocity field in
1378        do_stagger_fields_exchanges.F instead of in do_fields_blocking_exchanges.F
1379        (independent of using multi-dim advection or not); no effect on FWD run
1380        but affects AD results (at machine truncation level): update output of
1381        experiment 1D_ocean_ice_column (ad: 12 digits), hs94.1x64x5 (ad,oad: 13.d)
1382        and isomip (oad: 12.d).
1383    o pkg/generic_advdiff:
1384      - stop if doAB_onGtGs is set to FALSE but ignored
1385      - refine warning related to stability of tracer time-stepping
1386        regarding internal wave dynamics.
1387      - setting of AdamsBashforth_T,S when doAB_onGtGs=F: remove condition
1388        on staggerTimeStep & implicitIntGravWave (will now get a warning
1389        if potentially unstable).
1390    o pkg/kl10:
1391      - add new pkg "kl10" for mixing due to internal wave breaking, from
1392        http://www.sciencedirect.com/science/article/pii/S1463500310000144
1393        (contribution from Jody Klymak), tested in verification experiment
1394        verification/internal_wave/input.kl10/
1395    o isomip experiment:
1396      - test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up
1397        (input.htd) and update the output.
1398    o cd_code experiments:
1399      - use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM &
1400        #undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd)
1401        global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and
1402        update the corresponding output.
1403    o pkg/seaice:
1404      - reduce the number of include files and store directives in
1405        S/R seaice_lsr_tridiagu/v
1406      - change the order of loops in one case in S/R seaice_lsr_tridiagv
1407        (only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to
1408        get rid off one store directive (a TAF bug?)
1409      - add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in
1410        S/R seaice_lsr_tridiagv to change the loop range for consistency
1411      - remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v
1412      - fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in
1413        S/R seaice_lsr_tridiagu/v (requires update of
1414        offline_exf_seaice/input.dyn_jfnk)
1415    
1416    checkpoint65a (2014/07/27)
1417    o model/src:
1418      - Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than
1419        surrounding hFacC=1 @ edge of a step with different kSurfC on either side
1420        (topo in p-coords, ice-shelf in z-coords); update output of experiments
1421        tutorial_global_oce_in_p and isomip (both AD and OpenAD output).
1422    o model/src:
1423      - collect momentum forcing tendency into local 2-D array (passed as argument
1424        to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE
1425        parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default);
1426        affects results at machine truncation level (e.g., if using OBCS_SPONGE).
1427      - collect T & S forcing tendency into local 2-D array (passed as argument to
1428        apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency.
1429        affects results at machine truncation level (e.g., ocean: if using
1430        SHORTWAVE_HEATING ; atmos: if using FrictionHeating or (atm_Rq<>0) moist
1431        correction due to vertical advection).
1432      - update output of experiments: fizhi-cs-32x32x40 (13 digits),
1433        global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml:
1434        seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13),
1435        obcs_ctrl (ad & fwd grd @ 12 & 7).
1436    o pkg/ptracers & diagnostics:
1437      - use ptracers (short) name (instead of long one) to make ptracers diagnostics
1438        title (to avoid some unexpected truncation); sort out ptracers diags units.
1439      - collect ptracer forcing tendency into local 2-D array (passed as argument
1440        to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency.
1441    
1442    checkpoint65 (2014/07/18)
1443    o pkg/fizhi:
1444      - add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this
1445        affects results at machine truncation level. Update output of experiments
1446        fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits).
1447    o pkg/seaice: more clean up
1448      - rename TAF common block tapes to be more consistent and remove
1449        unnecessary duplicates
1450      - add store directives to remove more recomputations, but use smaller
1451        tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined.
1452        The idea behind this flag is to reduce the memory footprint when the
1453        adjoint of the LSR is not required. As of now, defining the flag
1454        SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by
1455        a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h).
1456        For experiment offline_exf_seaice, this means on a linux box with gfortran
1457        nearly a factor of 10 (but keep in mind there is mostly seaice code in
1458        this experiment):
1459        > size mitgcmuv_ad
1460        text    data        bss     dec        hex
1461        5100659 1216  220458952  225560827  d71c8fb
1462        5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER)
1463        but only a moderate increase of 36% for global_ocean.cs32x15:
1464        text    data        bss     dec        hex
1465        6695027 1648 1014578664 1021275339 3cdf6ccb
1466        6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER)
1467      - note: there are still recomputations in global_ocean.cs32x15 and
1468        offline_exf_seaice and the gradient agreement changes (gets a
1469        little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt)
1470      - in general, the AD gradients still are wrong
1471    o OpenAD
1472      - clean up code_oad/ directories somewhat by moving files
1473        dontCompile, dontTransform, keepOriginal to OAD_support/
1474    o model/src:
1475      - using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F
1476        (not currently tested): add dissipation terms before NLFS rescaling of
1477        tendencies (previously done after).
1478    o pkg/diagnostics:
1479      - write stats-diags in ascii file with more digits (same as in monitor).
1480    o pkg/down_slope:
1481      - drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with
1482        NLFS (not tested), use new recip_hFac value in order to conserve tracer.
1483    o model/src:
1484      - new file "apply_forcing.F" containing all the code previously in
1485        external_forcing.F, but with new argument list: pass, as new argument,
1486        the current level tendency array to update (instead of a direct update
1487        of the common bloc array). Change the corresponding calls.
1488      - add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use
1489        EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility).
1490    o pkg/seaice/seaice_lsr, a little bit of clean up
1491      - rearrange some code blocks, so that now all calculations for
1492        setting up the right-hand-sides done within one single block
1493        (I find that easier to read and understand)
1494      - rearrange freedrift-code to reduce the number of ifdefs
1495      - adjust some indentations and comments
1496    
1497    checkpoint64z (2014/07/10)
1498    o model/src and several pkgs:
1499      - change argument list of all S/R called from external_forcing.F and
1500        called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F)
1501        to pass, as argument, the current level tendency array to update
1502        (instead of a direct update of the common bloc array).
1503      - change also (in the same way) argument list of PTRACERS_APPLY_FORCING;
1504      - rename taueddy_external_forcing.f to taueddy_tendency_apply.F
1505    o pkg/seaice/seaice_lsr.F
1506      - always initialize local arrays in seaice_lsr_tridiagu/v
1507      - add more local tapes to seaice_lsr_tridiagu/v
1508      - move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but
1509        keep it in bi/bj loop; this seems to be essential
1510      - gradients are still wrong but only by 4-7 orders of magnitude
1511        instead of 15 orders of magnitude, lab_sea improves a little
1512    o pkg/seaice
1513      - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
1514        generates unnecessary code in seaice_lsr_ad
1515      - add more store directives in seaice_lsr to avoid unnecessary code
1516        in seaice_lsr_ad
1517      - exclude some residual computations in seaice_lsr when
1518        ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
1519        in seaice_lsr_ad
1520      - add more storing, a new tape (model/src/the_main_loop.F) and
1521        another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
1522        and klockey should be checked by a specialist)
1523      - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
1524        and update lab_sea after previous changes in pkg/seaice below
1525    o pkg/autodiff:
1526      - introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and
1527        viscFacInAd : run time parameters allowing for adjoint switches
1528        note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F
1529    o pkg/ecco:
1530      - introduce cost_gencost_boxmean.F that computes a box mean
1531        temperature (for use in adjoint sensitivity studies).
1532    o model/src/set_defaults.F : initialize viscFacAdj to 1.
1533    o pkg/mom_common/mom_calc_visc.F:
1534      - ifdef ALLOW_AUTODIFF then include viscFacAdj factor.
1535    o pkg/seaice/seaice_summary.F:
1536      - statement for SEAICEadjMODE now in autodiff_readparms.F
1537    o pkg/seaice:
1538      - remove some store directives and add new ones in an effort to get
1539        finally rid off the recomputation warnings. This is successful
1540        when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are
1541        defined (i.e. no extensive recomputation warnings left), but there
1542        are still too many recomputations on the solver iteration level
1543      - define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h
1544      - move definition of MPSEUDOTIMESTEPS into TAMC-block in
1545        SEAICE_SIZE.h
1546      - add a store directive in S/R seaice_calc_viscosities
1547    o pkg/seaice (ITD code):
1548      - fix definition of Hlimit for multi-threaded case
1549      - use double precision arithmetic to compute Hlimit: this affects results;
1550        update output of experiment seaice_itd.
1551    o replace content of verification/seaice_itd
1552      - instead of a 1D column use the configuration of offline_exf_seaice
1553        to test the ice thickness distribution code with ridging
1554      - this is a first shot at this experiment
1555      - change of some defaults of ridging parameters SEAICEhStar (from
1556        100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F
1557        and lot of new comments.
1558    
1559    checkpoint64y (2014/06/20)
1560    o pkg/seaice/seaice_reg_ridge.F:
1561      - modify the regularization of very small volumes of ice; only check
1562        total volume HEFF, and do not apply correction to individual ice
1563        classes because that leads to funny patterns in the heat and fw-fluxes
1564        into the ocean. Adjust seaice_itd/results/output.txt
1565      - replace nITD by SEAICE_multDim in loop-ranges
1566    o pkg/exf:
1567      - add code to process the case field period = -12. with UV interpolation.
1568      - move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec
1569        into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F)
1570    o verification/global_with_exf:
1571      - switch all fields period to -12. (was previously untested) in input/data.exf
1572        (but keep secondary test ".yearly" unchanged); update the reference output.
1573    o pkg/cal:
1574      - new calendar type "noLeapYear" for 365 days calendar without any leap year.
1575    o pkg/exf:
1576      - new integer parameter "exf_debugLev" (default set to main model debugLevel)
1577        to replace logical switch "exf_verbose"
1578      - report in STDOUT when loading a new record (if exf_debugLev >= 3)
1579    o pkg/sbo:
1580      - update from Katherine Quinn: evaluate mass directly from density and SSH
1581        (budget using Finite Volume method) instead of from bottom pressure.
1582      - allow testreport to collect few selected SBO output ; tested in exp.
1583        global_ocean.90x40x15 (after updating the results, to include SBO output).
1584      - fix some multi-threading issues (in output part).
1585    o model/src & most packages:
1586      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
1587      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
1588        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
1589        "data.{pkg}" exist ; and leave the S/R (return) just after.
1590      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
1591        + call LAND_READPARMS from packages_readparms.F
1592    o pkg/seaice:
1593      - remove code that resets useThSice in S/R seaice_readparms and
1594        replace it by a warning in S/R seaice_check
1595      - remove parameter MULTDIM, replace with nITD and runtime
1596        parameter SEAICE_multDim (still hard-wired to nITD if
1597        SEAICE_ITD is defined)
1598    
1599    checkpoint64x (2014/05/24)
1600    o verification/lab_sea:
1601      - update adjoint and TLM output following changes to pkg/salt_plume
1602      - un-do the update after putting back local recip_Cp in few places.
1603    o pkg/salt_plume: modifications by An Nguyen:
1604      - add capability to do brine rejection (salt-plume) as function of
1605        volume+tracers (instead of only salinity tracer).
1606      - conserve volume by exchanging volume from each kLev to above to
1607        accommodate in-coming brine volume
1608      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
1609      - switch KPP surf buoyancy due to brine forcing to 3-d
1610        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
1611      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
1612      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
1613        in East/West Arctic.
1614    o pkg/sbo:
1615      - incorporate modifications from Katherine Quinn to enable the use of sbo
1616        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
1617        output for future testreport verification (unfinished).
1618    o pkg/atm_phys:
1619      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
1620        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
1621        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
1622    o pkg/seaice
1623      seaice_calc_ice_strength.F: modify expression to avoid divisions
1624        (affects truncation)
1625      seaice_do_ridging.F: clean up the insectarium
1626      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
1627      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
1628      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
1629      - add some debugging information and error messages (warnings)
1630    o model/src: modifications relatd to atmosphere p*:
1631      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
1632      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
1633        of vertical profile tRef in geopotential background and anomaly.
1634      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
1635        and pkg/atm_phys.
1636      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
1637        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
1638    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
1639    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
1640        not used right now, but can be used in BGC packages to fix conservation.
1641    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
1642        other packages too.
1643    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
1644        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
1645    o model/src:
1646      - since we have several heat capacity (even in model/src), define "recip_Cp"
1647        as local variable (no longer in common block) to avoid any confusion.
1648      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
1649    o pkg/exf:
1650      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
1651        air density as function of air Temp, Humidity and atm pressure.
1652    
1653    checkpoint64w (2014/05/02)
1654    o verification:
1655      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
1656        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
1657        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
1658        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
1659        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
1660    o model/src: for atmosphere in p* coords:
1661      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
1662      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
1663        but not yet activated.
1664    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
1665      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
1666      - this changes the results (but not for any verification experiment, because
1667        none tests this), but avoids having an extra field in the restart files
1668    o pkg/seaice: remove global variable TICE (not needed)
1669      - replace by TICES or local variable where necessary (cost_seaice_test,
1670        seaice_diagnostics_state)
1671      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
1672      - use specific read/write routines for reading and writing individual leves
1673        of a multilevel field
1674    o pkg/ctrl & model/inc:
1675      - move additional anomaly fields of control vars (related to options:
1676         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
1677        from DYNVARS.h into new header file: CTRL_FIELDS.h
1678    o pkg/seaice: some small modifications to the ridging code
1679      - make fw2ObyRidge a global variable and add the freshwater flux to
1680        seaice_growth
1681      - pass actual thickness from seaice_prepare_ridging, so that it is
1682        computed only in one place and compute it in the same way as in
1683        seaice_growth
1684      - initialise more fields in seaice_do_ridging that where cause floating
1685        point exceptions over land
1686    o pkg/seaice: preparations for ridging code and first real ridging code
1687      - move most of "PART 1" of S/R seaice_growth into a new and separate
1688        S/R seaice_reg_ridge that will both regularize the state variable after
1689        advection call the actual ridging routine;
1690      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
1691        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
1692      - remove ridging code from seaice_advdiff
1693      - clean up remaining part 1 of seaice_growth in an attempt to make it
1694        more readable (this is probably subjective)
1695      - call seaice_itd_redist once in the initialisation phase to have the initial
1696        conditions in the correct category
1697      - finally: add new ridging routine for ITD code
1698    
1699    checkpoint64v (2014/04/11)
1700    o pkg/ecco:
1701      - add runtime parameters mdt[start,end]date[1,2]
1702      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
1703    o pkg/seaice:
1704      - make deltaC a global variable, so that it can be used in ridging code
1705      - first step towards ridging: introduce new routines that compute
1706        ice strength based on ridging parameters
1707      - add diagnostic for HSNOWITD
1708      - add opnWtrFrac as a global variable (required for ridging scheme)
1709    o pkg/salt_plume + pkg/seaice/seaice_growth.F
1710      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
1711        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
1712    o verification/hs94.1x64x5:
1713      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
1714      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
1715    o autodiff:
1716      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
1717        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
1718        For now, only in pkgs used in verification/hs94.1x64x5.
1719      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
1720        which are specific to TAF/TAMC).
1721      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
1722        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
1723        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
1724      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
1725        building mitgcmuv_ad (make adAll).
1726    o pkg/ecco:
1727      - cost_gencost_seaicev4.F:
1728         reformulate proxy cost as function of sst and local param SEAICE_freeze
1729         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
1730      - add stop statement if old names siv4-[sst,vol] are used
1731      - add snapshots + cost reports for atmospheric longwave
1732      - remove factor 0.1 in front of wtau[u,v]
1733      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
1734         ALLOW_TMI_SST_COST_CONTRIBUTION
1735    o pkg/atm_phys:
1736      - add some diagnostics for Short-wave and for convection S/R.
1737    o pkg/seaice/seaice_growth:
1738      - fix a bug in the lateral melt parameterization for SEAICE_ITD
1739        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
1740      - rearrange loop order for better vector code in the same code block
1741      - rewrite the floeDiameter formula to have fewer divisions
1742      -  (miraculously) none of this changes the results of seaice_itd
1743    o pkg/smooth:
1744      - move param smooth2Ddiffnbt to pkg/ecco
1745    o pkg/salt_plume:
1746      - salt_plume_frac.F:
1747         clean up local param names
1748         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
1749    o pkg/rw:
1750      - add RS version of S/R READ_MFLDS_LEV.
1751    o pkg/streamice:
1752      - fix the restart test by writing/reading pickup_streamice files.
1753    o pkg/seaice:
1754      - refine checks for jfnk-related parameters
1755      - comment out if statement with SEAICEuseIMEX parameter as long as there
1756        is no IMEX code to avoid confusion and surprises
1757    
1758    checkpoint64u (2014/03/07)
1759    o verification/MLAdjust:
1760      - rename secondary test suffix:
1761         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
1762         0.leithD -> AhFlxF  + switch to flux-form
1763         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
1764         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
1765    o pkg/mom_vecinv:
1766      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
1767        to be before mom_calc_visc.F)
1768      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
1769      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
1770        this is simpler for the adjoint and for diagnostics.
1771    o model/src + pkg/momentum:
1772      - add input files for  2-D additional Western and Southern cell-edge wall
1773         (e.g., to add "thin-wall" where it is =1).
1774      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
1775        using 2nd hFacZ that is computed from initial (fix domain) hFac
1776      - known limitations of thin wall implementation: not yet coded for sigma
1777        coords; not working with CD-scheme neither.
1778    o pkg/seaice:
1779      - rename recently introduced parameters from (wrong name) AB to
1780        BDF (backward difference time discretisation)
1781      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
1782    o tools/adjoint_options:
1783      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
1784    
1785    checkpoint64t (2014/02/01)
1786    o pkg/ecco
1787      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
1788        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
1789      - replace hard-coded record number and period which only work for monthly
1790        with read-in runtime param that works for other periods (month,day,year)
1791    o pkg/thsice
1792      - corrected store directive fixes thsice adjoint gradient checks
1793    o genmake2 & testreport:
1794      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
1795        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
1796        Update testreport accordingly. No need to set "export OPENAD=true"
1797        in adjoint_options/adjoint_oad anymore (will be removed later).
1798    o pkg/shelfice:
1799      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
1800        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
1801        so that surface forcing applies to k=kSurf if using pkg/shelfice.
1802    o pkg/ctrl, pkg/grdchk, pkg/ecco:
1803      - Changes to make GENARR more modular (i.e. invisible if not used)
1804    o model/src/temp_integrate.F and salt_integrate.F
1805      - re-include store directives that were removed on Dec 27th.
1806    o model/src/external_forcing_surf.F
1807      - add storage directives for EmPmR and PmEpR to avoid recomputation of
1808        seaice_model in the adjoint that is problematic when seaice_model is
1809        turned off in the adjoint. The resolved issue dated back to July when
1810        EXTERNAL_FORCING_SURF call was moved.
1811        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
1812    o pkg/exf/exf_check.F
1813      - fix a small bug again (originally found by Wentao Liu, now found again)
1814      - streamline error output
1815    o pkg/streamice and aim_v23:
1816      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
1817        Apple's /usr/bin/cpp knows what to do:
1818        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
1819        Target: x86_64-apple-darwin13.0.0
1820    
1821    checkpoint64s (2014/01/05)
1822    o tools/adjoint_options:
1823      - switch to fastopt.net TAF server (instead of default fastopt.de) for
1824        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
1825    o model/src:
1826      - remove some unnecessary TAF storage directives in forward_step.F and
1827        in dynamics.F (note: not always removed by TAF, e.g., double storage
1828        of kappaRU,kappaRV in former version of dynamics.F).
1829    o model/src & pkg/ptracers:
1830      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
1831        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
1832        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
1833      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
1834      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
1835      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
1836    o useSingleCpuInput separates single-CPU input from single-CPU output;
1837        for now only implemented for in exf_interp_read.F
1838    o verification/advect_xy:
1839      - fix missing EXCH call in local version of ini_salt.F and update output.
1840    o momentum diagnostics:
1841      - fix which deltaT is used in Total-Tendency diagnostics.
1842      - fix typo in diagnostics for momentum tendency from AB.
1843    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
1844        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
1845    
1846    checkpoint64r (2013/12/08)
1847    o verification/*/results:
1848      - Update reference output of experiments that were passing with just 13 digits
1849         (make it easier to detect future changes in results)
1850    o model/src & pkg/ptracers:
1851      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
1852        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
1853        to inside ptracers_integrate.F ; remove ptracers_advection.F
1854    o coupling interface pkgs:
1855        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
1856      - change the config check to test the agreement of Ocean Depth
1857        with ATM land/sea mask (instead of ATM orography);
1858      - send to coupler the number of coupler time-steps to do for this run:
1859        this allows to check for consistency and don't need anymore to be
1860        specified in parameter file "data";
1861      in coupler:
1862      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
1863      - improve report to log-file of config setting (pass log-file unit to few S/R)
1864    o pkg/compon_communic:
1865      - add coupling send/receive for non-tiled integer vector;
1866      - add S/R to check and stop if any proc has an error (similar to
1867        eesupp/src/stop_if_error.F but single thread and across Comm_World).
1868    o pkg/exch2:
1869      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
1870        through list of all tiles my proc owns.
1871    o model/src:
1872      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
1873        from rTrans) to simplify dependencies (no need to store rTrans anymore in
1874        calling S/R); this affects AD results at machine truncation level:
1875        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
1876        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
1877    o tools/build_options:
1878      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
1879    o coupling interface pkgs:
1880        [compon_communic, atm_compon_interf & ocn_compon_interf]
1881      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
1882        to each S/R that needs it; remove un-used variables.
1883      - change component tile registration (cpl_register.F in both compon_interf
1884        and mitcomponent_tile_register.F) to pass the full list of tiles
1885        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
1886      - with pkg/exch2: adopt the same convention used for I/O to define mapping
1887        towards coupler global array (unless W2_useE2ioLayOut=F):
1888         a) can now use different tiling between atm & ocn comp.
1889         b) no needs to modify the run-Off map when changing tiling (was needed
1890            even if using the same tiling between atm & ocn).
1891         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
1892            full land tiles); not yet tested.
1893      - check for valid mapping from comp. tile to coupler global array
1894      - improve report of tile registration results to log file.
1895    o pkg/exch2:
1896      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
1897        tile-registration (CPL_REGISTER);
1898      - activate (un-comment) definition and setting of "W2_tileIndex" list to
1899        store the local bi,bj indices of each tile;
1900      - also print bi,bj in local report to log file;
1901      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
1902        Jun 2009 modif of pkg/exch2).
1903    o testing on baudelaire:
1904      - run 2 tests at a time: no significant slow down (since enough cpu) and
1905        get the full set of test done earlier
1906      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
1907    o model/src/thermodynamics.F and routines called from it:
1908      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
1909        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
1910        velocity (outp) by adding bolus velocity.
1911      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
1912        mass transport from velocity + lateral grid cell area
1913      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
1914      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
1915     in thermodynamics.F
1916      - remove k from thermodynamics.F and move it to temp_integrate.F
1917        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
1918        loop).
1919      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
1920        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
1921        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
1922        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
1923      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
1924        global_ocean.90x40x15, tutorial_global_oce_biogeo and
1925        tutorial_tracer_adjsens (+ TLM output).
1926    o tools/OAD_support and (verification/*/) code_oad:
1927      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
1928        module conversion ; remove unneeded CPP_EEOPTIONS.h.
1929      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
1930        version (closer to model/inc/CPP_OPTIONS.h).
1931    o model/src:
1932      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
1933        retired list of parameters (routine FREEZE has been replace by surface
1934        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
1935    o pkg/gmredi:
1936      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
1937        velocity (same scheme but affects machine truncation) for GM_AdvForm.
1938      - update output of FWD experiments: front_relax.bvp,
1939        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
1940    
1941    checkpoint64q (2013/11/17)
1942    o verification:
1943      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
1944        tutorial_global_oce_biogeo and global_ocean.90x40x15.
1945      - generate new output (growth & melt) for seaice_itd experiment after
1946        updating the input pickup_seaice files (previously wrong).
1947    o pkg/cost:
1948      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
1949        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
1950        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
1951          cannot be applied to var in common block).
1952        o allows to get results independent of tile-per-proc setting (if using
1953          slower GLOBAL_SUM_SEND_RECV option).
1954      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
1955        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
1956        forward gradients: update output).
1957      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
1958        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
1959    o pkg/mom_common:
1960      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
1961        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
1962        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
1963        ensure that all field value that are used are set.
1964    o tutorial_deep_convection (smag3d):
1965      - add missing scaling in mom_calc_smag_3d.F;
1966      - set smag3D_coeff in input.smag3d such that results do not change.
1967    o pkg/dic:
1968      - change dic_cost.F to compute cost on each tile first and then apply
1969        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
1970        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
1971      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
1972    o eesupp/src & pkg/mdsio:
1973      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
1974        (from pkg/mdsio) since they are no longer used for tape IO.
1975      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
1976        (+ keep a copy in pkg/atm_ocn_coupler).
1977    o verification/isomip:
1978      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
1979    o tools/build_options:
1980      - optfile linux_amd64_ifort11, fast (no ieee) case:
1981        to get a working restart for all experiments, add "-fp-model source"
1982        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
1983    
1984    checkpoint64p (2013/10/20)
1985    o pkg/autodiff:
1986      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
1987        criteria, return to simple (default) tape IO format.
1988    o pkg/mdsio (+ eesupp/src):
1989      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
1990        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
1991      - fix globalFile and singleCpuIO options using simpler global mapping.
1992      - new pairs of scatter/gather vector S/R (one for each type, generated from
1993        template) corresponding to simpler global mapping.
1994      - adread_write.F: switch to new S/R (but leave old calls commented) and write
1995        to globalFile when parameter globalFiles is set to True.
1996      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
1997    o pkg/autodiff:
1998      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
1999        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
2000        missing, just add a STOP if array type do not match.
2001    o pkg/exf:
2002      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
2003         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
2004         and rename array obsSIce to exf_iceFraction.
2005    o tutorial_deep_convection:
2006      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
2007        for now all in this exp. code dir.
2008      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
2009        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
2010    o eesupp/src:
2011      - added SINGLE_DISK_IO option because reading of parameter files on
2012        very large number of processors did not work with existing set-up
2013    
2014    checkpoint64o (2013/09/25)
2015    o pkg/atm_phys & atm_compon_interf:
2016      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
2017    o tools/build_options:
2018      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
2019        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
2020        remove CPP setting (was identical to genmake2 default).
2021    o pkg/gmredi & model/src: Some updating and work done on the residual model.
2022      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
2023      - fixed up the calculation of the eddy stress and how it is added to the
2024        external forcing via taueddy_external_forcing.F
2025      - at the moment, it is very experimental and only works with the variable eddy
2026        diffusivity calculated in gmredi_k3d.F
2027    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
2028        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
2029    o testreport (& tools/do_tst_2+2):
2030      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
2031    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
2032      - remove CPP='cpp -traditional -P' (this is genmake2 default)
2033      - add switch (for big setups) to use 'medium' memory-model (but leave it
2034        commented out for now). Note: needed with FC 19 to compile big setups.
2035    o pkg/atm_compon_interf:
2036      - regroup per field origin (model & pkgs) the coupling storage routines
2037         (which accumalate in time each coupling field)
2038      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
2039        update accordingly + simplify aim_do_physics.F
2040    
2041    checkpoint64n (2013/08/26)
2042    o pkg/bbl:
2043      - update formulation to reduce dispersion of tracer properties in bbl
2044      - replaced horizontal and vertical transport parameters with velocities
2045      - changes results for verification/global_with_exf.yearly
2046    o verification/halfpipe_streamice:
2047      - change to matrix construction; update both Fwd & AD output.
2048    o verification/tutorial_tracer_adjsens:
2049      - OpenAD test: switch to vector-invariant momentum since fluxform with
2050        rStar causes problems with OpenAD; update output.
2051    o tools:
2052      - genmake2: define a common prefix for all temp-file names ; move them
2053        to local /tmp disk (but would be easy to move them back);
2054      - xmakedepend: apply the same switch for temp-files.
2055    o pkg/offline:
2056      - changes for use with rStar (NLFS): assume that we continue to provide
2057        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
2058        output files) and apply r* scaling at each time-step (function of the time
2059        varying Eta field); use normal pickup files (needed for restart with NLFS).
2060    o adjoint with OpenAD:
2061      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
2062        package openad.  This package has to be compiled for all runs with OpenAD
2063        instead of specifying code_oad_all as a modification directory.
2064      - link the fortran templates from tools/OAD_support to the build directory
2065        for preprocessing to avoid conflicts between different setups compiled
2066        simultaneously and simplify cleanup.
2067    o pkg/exf:
2068      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
2069        main model or other pkgs are exchanged in EXF_MAPFIELDS).
2070    o model/src:
2071      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
2072        (similar to do_fields_blocking_exchanges.F).
2073    o tools/genmake2:
2074      - remove TAF output src code just before calling staf (when not doing a fresh
2075        built, will stop if things go wrong with staf).
2076      - fix target "adobj" (left from TAF version-2 transition)
2077    o pkg/diagnostics:
2078      - add a parameter to track the status of pkg/diagnostics activation;
2079        this replace/extend the use of logical param "settingDiags" (to check
2080        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
2081        New S/R to print error message and stop when pkgStatus is not right.
2082      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
2083    
2084    checkpoint64m (2013/08/13)
2085    o model/inc:
2086      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
2087        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
2088    o pkg/kpp & aim_v23:
2089      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2090    o pkg/seaice:
2091      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
2092        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
2093      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
2094    o eesupp/src:
2095      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
2096        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
2097    o switch to TAF version-2:
2098      - add flow directives to "freeze" naming convention for ad-routines that
2099        are used in I/O routines of adjoint state and associated common blocks
2100        that are used in adcommon.h (backward compatible with version-1)
2101      - update all ad-optfiles (in tools/adjoint_options + few local to some
2102        verification exp) to switch to latest TAF version (currently 2.5.5);
2103        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
2104        out except for diva).
2105      - the major change with TAF version-2 is that both the differentiated
2106        routines and the forward routines (new) are returned as part of the TAF
2107        output source code. Update genmake2 accordingly.
2108      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
2109        with version-2 when compared to TLM or FWD gradient); other experiments
2110        output show minor changes (machine truncation level); update the few AD &
2111        TLM output with 12 matching digits only (some prior to version-2 switch).
2112    
2113    checkpoint64l (2013/08/05)
2114    o model/src:
2115      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
2116      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
2117        when using TAF but only if using OpenAD.
2118    o pkg/mom_common+fluxform+vecinv:
2119      - always set horiz. viscosity arrays to background value before calling
2120        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
2121        only when using variable horiz. viscosity (useVariableVisc=T);
2122      - simplify mom_vecinv.F (only 1 block for momViscosity).
2123    o pkg/mom_common: variable horiz. viscosity in NH code
2124      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
2125        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
2126      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
2127        useBiharmonicVisc & useVariableVisc.
2128      - fix old bug (already in 1rst implementation of variable horizontal viscosity
2129        in calc_gw.F, version 1.27, 2006/06/20):
2130        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
2131        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
2132      - change background horiz viscosity in vertical momentum (gW) to always be
2133        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
2134        any type of variable viscosity, e.g., viscAh/4Grid)
2135      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
2136        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
2137        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
2138        default viscAh,viscA4 is zero).
2139    o model/src:
2140      - extend length of drC & recip_drC from Nr to Nr+1.
2141    o Divided Adjoint (DIVA) with MPI:
2142      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
2143      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
2144        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
2145    
2146    checkpoint64k (2013/07/23)
2147    o tools/OAD_support:
2148      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
2149        and remove it from genmake2.
2150    o tools/build_options:
2151      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
2152        MPI_HEADER_FILES list (let genmake2 find the missing headers)
2153    o verification/halfpipe_streamice:
2154      - change to driving stress formulation; update both Fwd & AD output.
2155    o tools/genmake2 and Divided Adjoint with MPI:
2156      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
2157      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
2158      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
2159        Makefile, which is set by genmake2, and check which mpi-headers are needed.
2160        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
2161      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
2162    o testreport:
2163      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
2164        perform additional runs (number of additional runs is "add_DIVA_runs" taken
2165        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
2166    o verification/lab_sea (AD test):
2167      - change to test Divided Adjoint Run in this set-up (both standard AD test
2168        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
2169    o pkg atm_ & ocn_compon_interf:
2170      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
2171        staggerTimeStep implementation) and disable (retired) corresponding
2172        parameter.
2173    o pkg/offline:
2174      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
2175      - add S/R OFFLINE_CHECK to print offline parameter summary
2176        and stop if loading a file that is not used;
2177      - enable to calculate GMRedi tensor, KPP mixing and convective index
2178        when the corresponding file(s) is/are not specified (but pkg is used).
2179      - comment out resetting of monitorFreq (to endTime) since it still useful
2180        for monitoring CFL numbers and checking offline fields.
2181    o OpenAD:
2182      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
2183        smaller standard output) and generate new (smaller) output (on baudelaire
2184        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
2185    o model/src:
2186      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
2187        (where external_forcing_adjust was called) and change list of arguments;
2188      - merge external_forcing_adjust.F into external_forcing_surf.F
2189      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
2190        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
2191        previously in file "balance_relax.F", now removed); remove corresponding
2192        arrays in FFIELDS.h.
2193      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
2194        a hack for getting back surfaceForcingS (loaded from file) when using
2195        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
2196      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
2197        (was getting only 11 digits for AD-grad, due to different truncation
2198         error in AD code).
2199    
2200    checkpoint64j (2013/07/04)
2201    o pkg/offline:
2202      - to enable the use of other features with pkg offline (e.g., obcs),
2203        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
2204      - comment out "allowFreezing" (now active) in 2 offline testing exp.
2205    o pkg/exf ALLOW_RUNOFTEMP
2206      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
2207      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
2208      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
2209    o pkg/atm_phys:
2210      - allows to add some damping on uVel,vVel (strength only function of k).
2211    o verification, ad-tests:
2212      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
2213        global_ocean_ebm and offline_exf_seaice.thsice.
2214    o verification/halfpipe_streamice:
2215      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
2216        flux input boundary conditions to be ignored; a fix for this bug changed
2217        verification results for forward test.
2218      - add adjoint test.
2219    o pkg/ptracers:
2220      - allow to restart without SOM pickup (resetting SOM to zero).
2221    o pkg/gmredi:
2222      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
2223      - It uses mixing length theory and suppression by steering level effects to
2224        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
2225        to JPO, for more details).
2226      - It also uses the diffusivity to calculate an eddy induced streamfunction
2227        based on a PV closure (rather than a buoyancy closure as in GM).
2228      - New files added to pkg/gmredi:
2229        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
2230          induced overturning streamfunction (called from gmredi_calc_tensor)
2231        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
2232          for use in gmredi_k3d
2233        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
2234          the eddy diffusivity
2235    
2236    checkpoint64i (2013/06/18)
2237    o pkg/cheapaml:
2238      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
2239        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
2240        with pkg/cheapaml.
2241    o utils/python: add subpackage for cubed sphere function, first example is
2242        simple cs.pcol to plot 2D fields on a map
2243    o pkg/streamice:
2244      - This is a new package in MITgcm, which solves dynamic equations for ice
2245         sheets and ice streams
2246      - At the moment it is independent of atmosphere/ocean dynamics, or any
2247        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
2248        ed that this will change)
2249      - There is a new verification exercise that tests it, halfpipe_streamice,
2250        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
2251        rectangular embayment
2252      - halfpipe_streamice is forward-only for now, will have TAF test soon
2253      - for questions, email dgoldber@mit.edu
2254    o pkg/thsice:
2255      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
2256        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
2257      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
2258         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
2259      - allow precip from pkg/cheapaml to make snow over seaice.
2260    o pkg/cfc:
2261      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
2262      - remove atmos CFC 2-D arrays from common bloc (now local variables)
2263      - change some hard-coded constant to run time parameter for reading and
2264        and interpolating atmospheric CFC ; keep same default as previously.
2265      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
2266      - put arguments in standard order: myTime, myIter, myThid
2267      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
2268        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
2269      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
2270      - new routine to print summary of CFC params and check for consistency.
2271    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
2272      similar to thsice_advdiff.
2273      Note that for the B-grid case the routine parameters uc/vc are overwritten.
2274    o pkg/cfc:
2275      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
2276        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
2277      - fix interpolation of atmphspheric CFC between Sorthern and Northern
2278        hemisphere value.
2279    o pkg/seaice:
2280      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
2281    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
2282                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
2283      - requires an additional time level that is stored in the pickup
2284      - you can start with AB2 from a pickup without this time level with
2285        pickupStrictlyMatch = .false.
2286    
2287    checkpoint64h (2013/05/26)
2288    o pkg/cheapaml:
2289      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
2290        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
2291      - consistent treatment of uWind,vWind location: assume everywhere in
2292        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
2293        (Note: was already the case for Tair,Qair advection);
2294        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
2295      - compute diabatic forcing only in the interior (excluding overlap regions)
2296      - fill in array "Qsw" (for short-wave heating);
2297      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
2298        before any update (consistent with MITgcm state var diagnostics);
2299      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
2300        non periodic ; + adjusted for uWind,vWind (C-grid).
2301    o pkg/seaice:
2302      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
2303        add explicitly pkg/exf in experiments that currently use pkg/seaice.
2304      - allows to compile pkg/seaice without pkg/exf.
2305    o tools/OAD_support:
2306      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
2307        of array "ourStepOf" in function rvNextAction (revolve.F90).
2308    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
2309      - change pkg name (to be used with other atmospheric physics pkg)
2310        but by-pass CVS when making the new pkg so that we keep the CVS history.
2311    o pkg/offline:
2312      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
2313        (previously called from pkg/dic_surfforcing_init.F)
2314    o model/src:
2315      - re-order sequence of calls within packages_init_variables.F, using
2316        standard order, except for:
2317         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
2318         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
2319    o new pkg: atm_phys
2320      - add entry point and source code (previously in contrib
2321          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
2322        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
2323      - re-order sequence of calls within packages_readparms.F,
2324         packages_init_fixed.F and packages_write_pickup.F
2325        (but skip packages_init_variables.F because of TAF issues).
2326      - update contrib/*/atm_gray/ experiment.
2327    o pkg/seaice (ITD code):
2328      - simplify and fix the writing of pickup-files for ITD case
2329    o pkg/seaice (ITD code):
2330      - introduce floe size dependent lateral melt for ITD case;
2331      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
2332      - update seaice_itd experiment main output.
2333    o pkg/thsice:
2334      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
2335        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
2336        changed accordingly pkg/atm2d.
2337    
2338    checkpoint64g (2013/05/01)
2339    o pkg/exf ALLOW_RUNOFTEMP
2340      - if defined,  river and glacier runoff temperature can be read-in from
2341        runoftempfile; runoftempfile needs to have same format as runofffile
2342    o pkg/thsice (& pkg/bulk_force):
2343      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
2344        for energy content of Precip + RunOff & Evap (like with pkg/exf).
2345      - change computation domain to always be the interior (without overlap).
2346      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
2347    o verification/tutorial_global_oce_biogeo:
2348      - add preliminary OpenAD setup (still has problems)
2349    o pkg/seaice:
2350      - turn some parameters for choosing the convergence criterion of
2351        the inexact Newton method (JFNK) into runtime parameters for convenience
2352      - clean up seaice_calc_viscosities.F: remove/retire two options for
2353        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
2354        the results of lab_sea/input because a division has been replaced by
2355        a multiplication with the reciprocal (sumNorm)
2356      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
2357        convergence of solver (changes results, of course), and to test some
2358        new features
2359    o model/src:
2360      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
2361      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
2362      - move forcing adjustment (balancing surface forcing) in specific S/R
2363        where might also be applied exchanges (if needed) to forcing arrays.
2364    o pkg/shelfice:
2365      - allow to specify the Ice-Shelf mass per unit area (instead of
2366        shelficeLoadAnomaly) and do the conversion from one to the other
2367      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
2368        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
2369        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
2370        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
2371      - update isomip experiment forward output (get machine truncation error
2372        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
2373    o verification/offline_exf_seaice:
2374      revise data.seaice in input.thermo and input_ad and update results accordingly
2375        HO = 0.2, SEAICE_areaLossFormula = 2,
2376        SEAICE_growMeltByConv = .TRUE.,
2377        SEAICE_doOpenWaterMelt = .TRUE.,
2378      Improve consistency with input.thsice and fix the spurious 500m ice corners
2379    o verification/global_ocean.cs32x15:
2380      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
2381        in icedyn (thsice+seaice-dyn) test and update output.
2382    o verification/offline_exf_seaice:
2383      - adjust list of tested variables (with testreport) and update
2384        standard test output with better slection of monitored fields.
2385    o pkg/cd_code:
2386      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
2387        experiment lab_sea.hb87
2388    o tools/genmake2:
2389      - change default makedepend from the system default to tools/xmakedepend:
2390        When no makedepend is specified, select tools/xmakedepend it the test pass,
2391        otherwise select the system default (if exist and pass the test) or
2392        try to build cyrus-makedepend ; stop if none of the 3 works.
2393    o pkg/exf & pkg/thsice:
2394      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
2395        for energy content of Precip + RunOff & Evap. Assumes:
2396       1) Rain has same temp as Air.
2397       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
2398       3) Run-Off comes at the temp of surface water (with same Cp)
2399       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
2400        put directly into Latent Heat flux & should use water-vapor heat capacity.
2401       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
2402        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
2403    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
2404        (compile when SEAICE_ALLOW_JFNK is defined)
2405    o pkg/thsice:
2406      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
2407        implementation): move THSICE_AVE call after the advection (called directly
2408        from thsice_do_advect.F).
2409    o verification/global_ocean.90x40x15 and OpenAD:
2410      New experiment for OpenAD is identical to the one in input_ad except that
2411        multiDimAdvection=.FALSE.,
2412      There is still an issue with this.
2413    o pkg/thsice:
2414      - account for ice velocity (ocean relative velocity) in turbulent heat flux
2415        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
2416        and offline_exf_seaice (main test).
2417    
2418    checkpoint64f (2013/03/31)
2419    o verification/OpenAD:
2420      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
2421    o verification/isomip, pkg/shelfice and OpenAD:
2422      - add OpenAD setup to this exp and make shelfice package work with OpenAD
2423    o verification/tutorial_global_oce_biogeo:
2424      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
2425    o verification/offline_exf_seaice:
2426      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
2427    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
2428      - add OpenAD setup to this exp and make ptracers package work with OpenAD
2429    o pkg/seaice/seaice_evp.F:
2430       mask the asymmetric contribution of the ice-ocean stress (when
2431       the turningAngle is non-zero) over open water to avoid stripes
2432       in the EVP-solutions after many EVP-substeps. This does not change
2433       the verification experiment (because turningAngle=0 in that experiment),
2434       but will affect other EVP solutions with turningAngle.ne.0
2435    o verification, AD & TLM output:
2436      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
2437        additions and multiplications which affect results at machine truncation
2438        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
2439        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
2440        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
2441        digits of matching.
2442    o pkg/seaice:
2443       modify lsr-algorithm so that it vectorizes AND converges by using a
2444       "zebra" method: split vector loop into two with step size 2; this
2445       solves a general convergence problem for the JFNK solver on a vector
2446       computer. It has the potential to even improve convergence for
2447       non-vector machines, but it does change the results so it is turned
2448       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
2449       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
2450    
2451    checkpoint64e (2013/03/05)
2452    o pkg/ecco and several verification experiments:
2453       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
2454       from ecco package, and revert to unified routine in model/src/
2455       Adjust verification experiments accordingly, especially gloal_oce_llc90
2456       Should conclude long-standing work by Gael to reconsile the_main_loop with
2457       ECCO and will enable OpenAD's revolve loop in ECCO setup.
2458    o pkg/generic_advdiff:
2459      - implement compressible flow method for multi-dim advection (similar to
2460        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
2461        TAF generates many recomputations) to use it; no yet coded with implicit
2462        vertical advection.
2463      - change experiment advect_cs (new output) and advect_xy (same output)
2464        to test compressible flow multi-dim advection.
2465    o pkg/generic_advdiff:
2466      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
2467        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
2468    o pkg/seaice:
2469      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
2470        bug affects two verification experiments (lab_sea and lab_sea.hb87),
2471        recover old (wrong) results by setting noSlipFac = 2. in
2472        seaice_calc_strainrates.F;
2473      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
2474      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
2475        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
2476      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
2477    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
2478      - new subroutines seaice_lsr_tridiagu/v
2479      - introduce loop bounds i/jmin/max to be able to use a restricted
2480        additive Schwarz method, but not used for now.
2481      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
2482      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
2483    o OpenAD support
2484       Reorganize S/R call for overall time-stepping loop to facilitate
2485       OpenAD revolve loop replacement
2486       (new S/R main_do_loop.F)
2487    o model/src:
2488      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
2489      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
2490        ADAMS_BASHFORTH2.
2491    o pkg/cheapaml:
2492      - add new parameter (default=F, same as before) to disable full domain
2493        (including land) periodicity in X & Y dir.
2494      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
2495        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
2496        into single S/R CHEAPAML_TIMESTEP.
2497    
2498    checkpoint64d (2013/02/17)
2499    o pkg/monitor (angular momentum):
2500      - do not add Eta contribution to the total AM if using rigid-lid;
2501      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
2502      - horizontal discretisation: compute Zonal wind contribution separately for
2503        each component (instead of from cell centered averaged) and use the 4
2504        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
2505      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
2506        FreeSurf) if using vectorInvariant momentum.
2507    o model/src (horizontal grid):
2508      - move initialisation of all horizontal grid arrays to null value
2509        from specific horizontal grid S/R to main S/R INI_GRID;
2510      - add 2 new arrays to project model C-grid velocity on to zonal direction
2511        (similar to AngleCosC & -AngleSinC but at U and V point location) and
2512        compute them in S/R CALC_GRID_ANGLES.
2513    o pkg/seaice: replace a hard coded parameter by a runtime parameter
2514        SEAICE_JFNK_tolIter
2515    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
2516        preconditioner for JFNK (run LSR into the overlaps as far as possible,
2517        i.e OLx/y-2, but overwrite the solution in the overlaps)
2518      - extend loop range in seaice_calc_viscosity
2519      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
2520      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
2521      - slightly modify loops in tridiagonal solver lsr-preconditioner
2522      - by default remove the extra exchange in seaice_preconditioner with a
2523        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
2524      - modify offline_exf_seaice so that old results without RAS are reproduced
2525        for output.dyn_jfnk.txt
2526      in seaice_fgmres.F (unrelated to RAS)
2527      - add a cpp-flag option for a re-ordered mapping (potentially more
2528        efficient), but because this changes the results, turn it off by
2529        default
2530      - replace the save statement by local common blocks
2531    o utils/matlab:
2532      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
2533      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
2534        instead of local script "load_cs.m".
2535    o pkg/seaice:
2536      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
2537        to the scalarProductMetric and the unrolling. By chance this does not
2538        change the verification experiment, because of the particular domain
2539        decomposition
2540    o pkg/diagnostics:
2541      - change default missing_value from UNSET_RL to -999.
2542    o pkg/layers: improve vectorization of layers_fluxcalc.F
2543      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
2544        time spent in this routine by more than a factor of 3 on an NEC-SX8
2545      - step 2: replace search algorithm by a bisection algorithm found in
2546        Press et al. Numerical Recipes in Fortran. This algorithm can be
2547        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
2548        For now, use this algorithm only for TARGET_NEC_SX defined.
2549      - moved the search algorithm into a separate subroutine, that is kept
2550        within the same file for automatic inlining.
2551      - modified catching potential errors
2552    o pkg/ecco:
2553      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
2554    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
2555      - modifications for ALLOW_GENTIM2D_CONTROL
2556      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
2557      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
2558      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
2559      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
2560    o model/src:
2561      - account for moist thermodynamics in (dry) potential temperature equation;
2562        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
2563        and cpl_aim+ocn.
2564      - also switch to standard compiler (gfortran, was using ifort previously)
2565        for fizhi-cs experiments reference output.
2566    o pkg/ctrl:
2567      - 1st step toward generic time-varying control variable (2D) via CPP option
2568        ALLOW_GENTIM2D_CONTROL
2569      - note new namelist ctrl_nml_genarr in data.ctrl
2570    o verification/global_ocean.cs32x15:
2571      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
2572        thsice calling sequence and update "output.icedyn.txt" output file.
2573    o pkg/ptracers:
2574      - from Ryan A.: code to allow to restart a tracer at regular time interval
2575        specifying a reset frequency and a reset-phase (for each tracers).
2576    o pkg/thsice:
2577      - implement new sequence of calls for thsice+seaice:
2578          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
2579          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
2580      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
2581        in CPP_OPTIONS.h) to recover old sequence;
2582      - update diagnostics for Intermediate State thsice diagnostics: now filled
2583        just before advection (instead of just after advection in old sequence);
2584      - update output of experiment offline_exf_seaice (standard test);
2585      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
2586        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
2587    o pkg/aim_v23:
2588      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
2589      - use standard pkg/mdsio routines to read & write CO2 pickup file;
2590      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
2591      - Implement new sequence of calls for seaice advection (with thsice and
2592        seaice diffusion): do ice advection after ice-Thermodynamic (previously
2593        was done before); change aim_do_physics.F (split the bi,bj loops block);
2594      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
2595    o pkg/thsice:
2596      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
2597        where just seaice diffusion is used without seaice-dynamics.
2598    
2599    checkpoint64c (2013/01/18)
2600    o pkg/seaice:
2601      - add a parameter JFNKres_tFac that can replace JFNKres_t
2602        (= JFNKres_tFac*JFNKresidual before JFNK solver)
2603      - add a line search option to the JFNK solver
2604      - move update of u/vIce and computation of initial residual into a separate
2605        routine (same file); makes the code a little easier to read (?)
2606      - the line search requires computation of the residual and for some reason
2607        I cannot do the update of u/vIce at the beginning of the Newton loop
2608        without changing the results, so we move computation of the new residual
2609        also to the end of the Newton loop, even without the line search
2610    o pkg/mdsio:
2611      - write missing value (corresponding to undefined array value) to meta files;
2612        skip this if missing value is one (UNSET_RL would be a better value for the
2613        case of undefined missing value but it's current the default missing-value);
2614        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
2615    o pkg/exf & thsice:
2616      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
2617        diagnostics) even when SHORTWAVE_HEATING is #undef;
2618    o verification/cfc_example:
2619      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
2620        illustrate how to use it).
2621    o verification/offline_exf_seaice:
2622      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
2623        files to only one time-record.
2624      in input.thermo: narrow the 2 bands of low initial ice-concentration near
2625        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
2626        snapshot output; same mcPheePiston value as in thsice with
2627        surf-current=0.2m/s.
2628      in input.thsice: similar set-up as in input.thermo (channel with same seaice
2629        initial conditions).
2630    o verification/cfc_example:
2631      - update file "data" with more standard choice (default rotationPeriod,
2632        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
2633        set deltaTFreeSurf to deltaTtracer) and update the output.
2634    o pkg/layers:
2635      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
2636      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
2637    o verification/offline_exf_seaice:
2638      - set all {field}period to zero for constant-in-time forcing (not tested
2639        anywhere else).
2640    o verification/offline_exf_seaice:
2641      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
2642      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
2643    o model/src:
2644      - implement Finite-Volume method for (hydrostatic) presure gradient
2645        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
2646    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
2647      - In order to be compatible with the default EVP code, this requires changing
2648        the EVP code around a little; and because any small change immediately
2649        breaks the lab_sea.hb87 verification experiment, the reference output is
2650        updated two times (each time the remaining aggrement was only 2 digits):
2651        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
2652        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
2653        The adjoint test lab_sea.evp also needed to be updated.
2654      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
2655        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
2656        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
2657        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
2658        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
2659        kept obscure, because I need to test it a little more.
2660    o pkg/cheapaml:
2661      - fix few incorrect type (_RL/_RS) in subroutine calls.
2662    o pkg/seaice:
2663      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
2664        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
2665    o model/src:
2666      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
2667        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
2668        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
2669    o pkg/cheapaml:
2670      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
2671        update output of experiment cheapAML_box.
2672      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
2673        and set them only in one place (cheapaml_readparms.F).
2674      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
2675      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
2676        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
2677    o model/src/the_main_loop.F:
2678      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
2679    o pkg/seaice:
2680      - remove legacy branch code.
2681      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
2682    o verification/*/code*/SEAICE_OPTIONS.h:
2683      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
2684        SEAICE_CAP_HEFF).
2685    o pkg/cheapaml:
2686      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
2687        to load new forcing fields.
2688      - add missing "_d 0" where it's needed; + some editing (improve indentation).
2689      - remove switch to "-r8" compiler option (no longer needed) in verification
2690        cheapAML_box, keep same output (small trucation error differences).
2691    o verification/offline_exf_seaice:
2692      - add thermodynamics only test.
2693    o verification/cheapAML_box:
2694      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
2695        keep same output (same 14 digits for cg2d).
2696      - switch on "-r8" compiler option (some numerical values are missing
2697        the "_d 0") and update output (only 6 digits for cg2d were preserved).
2698    
2699    checkpoint64b (2012/12/24)
2700    o pkg/cheapaml:
2701      - remove un-used variables (Qnet,EmPmR) from pickup files.
2702      - store tendency of advected variables into cheapaml pickup file
2703        and fix the AB-2 restart.
2704    o verification/offline_exf_seaice and lab_sea adjoint:
2705      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
2706      - switch to 4 time steps in offline, consistent with lab_sea.
2707      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
2708      - update results after change of experiment seaice.
2709    o pkg/seaice:
2710      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
2711        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
2712        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
2713        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
2714    o model/src:
2715      - add run-time parameter to select CG2D solver minimum-residual solution
2716        (in case of a poor convergence).
2717    o pkg/seaice/seaice_lsr.F
2718      - move calculation of matrix coefficients into new
2719        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
2720        file; the main purpose of this change is to be able to reuse the code
2721        in S/R SEAICE_PRECONDITIONER
2722      - modify the computation of the residual so that the mass of sea-ice
2723        is not used twice; this simplifies the calculations, but since
2724        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
2725        not tested in testreport---this does not affect the testreport results.
2726    o verification/seaice_obcs:
2727      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
2728        verification/lab_sea/input.salt_plume; changes results/output.txt*
2729    o model/src:
2730      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
2731    o pkg/seaice:
2732      - improve description of parameters in seaice_fgmres.F and start
2733        cleaning up the code
2734      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
2735        second argument
2736      - add a metric based on grid cell area to SEAICE_SCALPROD; update
2737        results of offline_exf_seaice.dyn_jfnk
2738      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
2739    o pkg/aim_v23:
2740      - fix an other bug in dissipation heating (grid-cell area was missing).
2741    o model/src + pkg/seaice:
2742      - add global (multi-tile) linear solver for pair of tri-diagonal system
2743        along X and Y lines, respectively for U and V component.
2744        Note: 1) MPI and cube-exchange not yet coded.
2745            2) probably not accurate for poorly conditioned / large size problem.
2746      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
2747        default: not compiled and not used.
2748    o pkg/seaice:
2749      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
2750        introduce bi/bj loops and use global_sum_tile_rl instead of
2751        mpi_allreduce in seaice_fgmres.F
2752      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
2753      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
2754      - add a verification experiment for JFNK in offline_exf_seaice
2755    o verification:
2756      - change (for now, only fwd test) offline_exf_seaice experiment:
2757        use a re-entrant channel with idealized coastline (trapezoidal shape)
2758        at southern boundary to explore seaice dynamics and thermodynamics
2759        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
2760        secondary test (input.thsice) use thermodynamics only with SST relaxation.
2761      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
2762    o pkg/exf:
2763      - disable "sstExtrapol" when Nr=1
2764    o verification:
2765      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
2766        to test pkg/cheapaml.
2767    o pkg/aim_v23 & pkg/shap_filt:
2768      - fix dissipation heating (erroneous gravity multiplication factor).
2769    o pkg/seaice:
2770      - remove unused field pressPre from jfnk solver
2771      - rename two subroutines in seaice_preconditioner.F
2772    o eesupp/src:
2773       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
2774    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
2775       - remove wrong parts of the rhs and the lhs (were in there
2776         because I did not understand the concept of this preconditioner)
2777       - add an exchange between u- and v-sweep. This increases communication
2778         by a factor of two but improves the convergence of jfnk. Ideally,
2779         one would like the u- and v-sweep to be independent. So far within
2780         undocumented ifdefs
2781       - reorganize the extra computations for printing the residuals
2782    o tools/genmake2:
2783      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
2784        since it's not necessary (and was preventing to use MNC in some cases).
2785    
2786    checkpoint64a (2012/11/16)
2787    o pkg/autodiff:
2788      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
2789        autodiff_readparms.F no longer depends on calling order (within
2790        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
2791        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
2792        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
2793    o pkg/obcs:
2794      - adding tidal velocity forcing capability to obcs
2795        for usage example, see verification/seaice_obcs/input.tides
2796    o pkg/seaice:
2797      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
2798        SEAICE_LSRrelaxU/V
2799      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
2800    o pkg/aim_v23:
2801      - implement heating from friction (bottom friction and stratospheric drag).
2802    o pkg/shap_filt:
2803      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
2804        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
2805    o model/src:
2806      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
2807        time-constant addMass field from file (addMassFile);
2808      - support for heating due to friction (and Kinetic Energy dissipation):
2809        add option, run-time switch and 3-D field array + support code ; each pkg
2810        or S/R can add heating contribution (if there is a sink of KE); the sum is
2811        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
2812    o pkg/seaice:
2813      - complete merge of ITD code into seaice_growth.F
2814        from MITgcm_contrib/torge/itd/code/
2815        no verification so far, but Torge Martin tested
2816        "1-D test case and Beaufort set up;
2817        deliver okay results after 1 model year."
2818      - complete merge of SEAICE_SIZE.h into all relevant routines
2819      - move computation of eta at Z-points into calc_viscosities
2820        + introduce global field etaZ
2821        + add different methods for computing etaZ, for now the old
2822          method (simple averages of eta to Z-points) is hardwired
2823        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
2824          seaice_preconditioner
2825      - simplify computations for SEAICE_ZETA_SMOOTHREG
2826      - seaice_preconditioner:
2827        + replace one remaining press by pressLoc (mistake)
2828        + adjust printing of residuals
2829      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
2830        + add (SEAICE.h) and rename some counters (initiliased in
2831          seaice_init_fixed.F)
2832        + add _BEGIN/END_MASTER (myThid)  around print statements
2833        + print total number of iterations and failures over SEAICE_monFreq
2834          interval to STDOUT
2835      - move control over output-messages by fgmres to seaice_jfnk to save
2836        some operations
2837      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
2838        in order to make restarts with sol .ne. zero (fgmres with restarts)
2839        (seaice_jfnk.F, seaice_fgmres.F)
2840      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
2841        a serious convergence problem when open boundaries are involved
2842    o pkg/ggl90: fix computation of control volumes for the case of
2843      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
2844      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
2845    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
2846    o pkg/autodiff
2847      - Add inAdMode switch for SEAICEuseDYNAMICS:
2848        SEAICEuseDYNAMICSinAdMode
2849        (extend logic in ADAUTODIFF_INADMODE_SET)
2850    o pkg/seaice
2851      - Step 1 of merging ice-thickness distribution (ITD) code from
2852        MITgcm_contrib/torge/itd/ (author: Torge Martin)
2853        The code implements concept laid out in Thorndike et al. (1975);
2854        code is enabled via CPP flag SEAICE_ITD
2855        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
2856        code is not complete yet!!
2857      - SEAICE_SIZE.h now included in almost all seaice routines
2858    o verification (using seaice):
2859      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
2860        global_ocean.cs32x15.seaice ; update results.
2861      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
2862      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
2863        offline_exf_seaice (previously compiling B-grid).
2864    o pkg/exf:
2865      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
2866        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
2867        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
2868    o pkg/layers (adjust changes from Sept 19):
2869      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
2870        this allows to remove "layers_maxNum" dimension from all layers arrays.
2871    o pkg/layers (adjust changes from Sept 19):
2872      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
2873      - snap-shot extended to all type of layers (not just the 1rst type);
2874      - remove layers variables when corresponding CPP option is undef.
2875    o pkg/layers:
2876      - rename pkg/layers variable and add new output (layer exist & un-weighted
2877        velocity in layer)
2878    o pkg/seaice:
2879      - simplify (?) ocean-drag coefficent computations by using
2880        the same routine in all three solvers (saves some code lines)
2881      - remove global fields DRAGA and DRAGS from C-grid code and
2882        declare them locally in lsr.F (the only place where they are
2883        still used)
2884      - update AD output of lab_sea.evp (very sensitive anyway).
2885    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
2886      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
2887      and SEAICEuseJFNK=.true. A few things to note:
2888      - involves a FGMRES, that is parallel but very inefficient,
2889        because of many scalar products (global sums) in the Gram-Schmidt
2890        orthogonalization method. Needs to be replaced. Original code
2891        from J.-F. Lemieux
2892      - preconditioner for FGMRES is a stripped down version of LSOR
2893      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
2894        preconditioner. For the preconditioner, the default is set to 10.
2895      - Jacobian times vector is computed with finite differences
2896      - marginally related to JFNK-solver: add a smooth regularization for
2897        zeta with tanh that will improve convergence (Lemieux and Tremblay,
2898        2009) for any implicit solver (not implemented for EVP because EVP
2899        does not need this regularization in the first place). Define
2900        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
2901    o eesupp/src:
2902      - check in genmake2 that intrinsic S/R flush is available.
2903      - add S/R to flush IO unit (if intrinsic S/R flush is available)
2904      - flush standard & error msg unit before MPI termination
2905      - if debugMode, flush IO unit after printing msg
2906    o pkg/ctrl:
2907      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
2908        to ctrl_set_unpack_xyz.
2909    
2910    checkpoint64 (2012/10/09)
2911    o pkg/shelfice
2912      - in mom_fluxform.F, mom_vecinv.F:
2913        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
2914        Bug fix KappaRU -> KappaRV
2915        does not change verification/isomip but may change other setups
2916        (presumably constant KappaRU=KappaRV)
2917      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
2918    o pkg/obcs:
2919      - fixed some indexing bugs in obcs_seaice_sponge.F
2920      - added obcs relaxation subroutines for HSALT and HSNOW
2921      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
2922    o pkg/seaice:
2923      - add "multicategory" parameterization for snow in analogy to ice,
2924        default is off for now.
2925    o pkg/obcs:
2926      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
2927        see verification/seaice_obcs/input.seaiceSponge for example application.
2928      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
2929        index setting by master-thread. This fix multi-threads Pb in previous modifs.
2930    o pkg/layers :
2931      - add diagnostics to pkg/layers
2932      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
2933        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
2934    o pkg/generic_advdiff/gad_implicit_r.F :
2935      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
2936    o pkg/seaice/seaice_growth.F:
2937      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
2938    o pkg/obcs:
2939      - change default setting of OBCS_UVICE_OLD from defined to undef;
2940      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
2941        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
2942      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
2943      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
2944        with Southern & Western OB at a tile edge (at least in a simple set-up).
2945    o pkg/obcs:
2946      - change settings of OB index in case OB coincides with tile edge (shared by
2947        2 tiles), so that common OB location is registered by both tiles (instead of
2948        only 1). However, for Southern and Western OB, index value = 0 is not
2949        recognized as valid OB index (=default null value) and needs to be fixed.
2950      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
2951      - new parameter "OB_indexNone" for null index value (for now, still zero)
2952        to replace hard-coded null index value of zero.
2953    o pkg/exch2:
2954      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
2955        always check buffer-size (but outside the loop); move checking for valid
2956        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
2957        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
2958    o pkg/ctrl (pack & unpack):
2959      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
2960        (locally defined) for different variables (+ remove the variable-specific
2961        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
2962        (to be extended to other local file names in ctrl.h).
2963    o pkg/flt:
2964      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
2965    o pkg/mdsio:
2966      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
2967    o tools/genmake2:
2968      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
2969        (added by Alistair in version 1.51 for building without make depend);
2970      - remove Header files list (H_SRC_FILES) from the dependence of targets
2971         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
2972        place in version 1.23): this save going through staf when unrelated header
2973        file has been modified.
2974       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
2975        "make depend" step, still need to do "make links" before "make adtaf".
2976    o eesupp/src (+ few pkg src files) & genmake2:
2977      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
2978      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
2979      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
2980         upper/lower case ; account for space between "#" and undef/define)
2981    o pkg/flt (with exch2):
2982      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
2983      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
2984    
2985    checkpoint63s (2012/09/05)
2986    o pkg/ecco:
2987      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
2988      - add more relevant #ifdef ALLOW_SMOOTH ones.
2989      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
2990    o pkg/ctrl:
2991      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
2992        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
2993      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
2994        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
2995        ctrlSmoothCorrel3D (new).
2996        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
2997      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
2998      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
2999        controls when useAtmWind, and vice versa.
3000      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
3001      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
3002          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
3003      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
3004          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
3005      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
3006        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
3007    o pkg/smooth:
3008      - remove un-necessary includes.
3009      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
3010        Those CPP options were never defined, and not necessary.
3011    o model/src:
3012      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
3013      - standard treatment of useSMOOTH.
3014    o pkg/autodiff:
3015      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
3016        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
3017    o pkg/exch2:
3018      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
3019        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
3020      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
3021        and tiles to process mapping.
3022      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
3023        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
3024        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
3025        from w2_eeboot.F to w2_readparms.F.
3026    o eesupp/src:
3027      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
3028        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
3029        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
3030      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
3031        is defined (remove condition on usingMPI) to match cases where MPI_INIT
3032        has been called.
3033      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
3034      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
3035        (so that on 1 proc, get same myPid independently of usingMPI)
3036      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
3037        useCubedSphereExchange with EXCH-1 (safer).
3038      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
3039    o pkg/ggl90:
3040      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
3041        used in ALLOW_GGL90_SMOOTH code.
3042    o pkg/flt:
3043      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
3044        floats at the Southern end of the domain).
3045    o eesupp/inc:
3046      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
3047        but not used (and not to be used) anywhere, just for documentation.
3048    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
3049      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
3050        a) can damage previously written records in any other multi-record files.
3051        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
3052  o tools/genmake2:  o tools/genmake2:
3053    - define variable MAKE within Makefile and use it in place of 'make';    - define variable MAKE within Makefile and use it in place of 'make';
3054    - update AD_CONFIG.h (if needed) before building any of the executable    - update AD_CONFIG.h (if needed) before building any of the executable
# Line 11  o tools/genmake2: Line 3056  o tools/genmake2:
3056      and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;      and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
3057    - always print usual warning comment 'this file is automatically generated'    - always print usual warning comment 'this file is automatically generated'
3058      from script convert_cpp_cmd2defines (+ remove this warning from genmake2).      from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
3059    o pkg/cheapaml:
3060      - updated to correspond to the code used in accepted paper (Nico Wienders).
3061  o pkg/exf:  o pkg/exf:
3062      added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.      added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
3063      ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)      ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
