4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - since we have several heat capacity (even in model/src), define "recip_Cp"
9        as local variable (no longer in common block) to avoid any confusion.
10      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
11    o pkg/exf:
12      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
13        air density as function of air Temp, Humidity and atm pressure.
14    
15    checkpoint64w (2014/05/02)
16    o verification:
17      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
18        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
19        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
20        affects AD gradient (down to 8-7 matching digits for global_ocean and
21        5-6 for lab_sea).
22    seaice_reg_ridge.F seaice_do_ridging.F
23    o model/src: for atmosphere in p* coords:
24      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
25      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
26        but not yet activated.
27    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
28      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
29      - this changes the results (but not for any verification experiment, because
30        none tests this), but avoids having an extra field in the restart files
31    o pkg/seaice: remove global variable TICE (not needed)
32      - replace by TICES or local variable where necessary (cost_seaice_test,
33        seaice_diagnostics_state)
34      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
35      - use specific read/write routines for reading and writing individual leves
36        of a multilevel field
37    o pkg/ctrl & model/inc:
38      - move additional anomaly fields of control vars (related to options:
39         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
40        from DYNVARS.h into new header file: CTRL_FIELDS.h
41    o pkg/seaice: some small modifications to the ridging code
42      - make fw2ObyRidge a global variable and add the freshwater flux to
43        seaice_growth
44      - pass actual thickness from seaice_prepare_ridging, so that it is
45        computed only in one place and compute it in the same way as in
46        seaice_growth
47      - initialise more fields in seaice_do_ridging that where cause floating
48        point exceptions over land
49    o pkg/seaice: preparations for ridging code and first real ridging code
50      - move most of "PART 1" of S/R seaice_growth into a new and separate
51        S/R seaice_reg_ridge that will both regularize the state variable after
52        advection call the actual ridging routine;
53      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
54        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
55      - remove ridging code from seaice_advdiff
56      - clean up remaining part 1 of seaice_growth in an attempt to make it
57        more readable (this is probably subjective)
58      - call seaice_itd_redist once in the initialisation phase to have the initial
59        conditions in the correct category
60      - finally: add new ridging routine for ITD code
61    
62    checkpoint64v (2014/04/11)
63    o pkg/ecco:
64      - add runtime parameters mdt[start,end]date[1,2]
65      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
66    o pkg/seaice:
67      - make deltaC a global variable, so that it can be used in ridging code
68      - first step towards ridging: introduce new routines that compute
69        ice strength based on ridging parameters
70      - add diagnostic for HSNOWITD
71      - add opnWtrFrac as a global variable (required for ridging scheme)
72    o pkg/salt_plume + pkg/seaice/seaice_growth.F
73      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
74        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
75    o verification/hs94.1x64x5:
76      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
77      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
78    o autodiff:
79      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
80        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
81        For now, only in pkgs used in verification/hs94.1x64x5.
82      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
83        which are specific to TAF/TAMC).
84      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
85        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
86        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
87      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
88        building mitgcmuv_ad (make adAll).
89    o pkg/ecco:
90      - cost_gencost_seaicev4.F:
91         reformulate proxy cost as function of sst and local param SEAICE_freeze
92         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
93      - add stop statement if old names siv4-[sst,vol] are used
94      - add snapshots + cost reports for atmospheric longwave
95      - remove factor 0.1 in front of wtau[u,v]
96      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
97         ALLOW_TMI_SST_COST_CONTRIBUTION
98    o pkg/atm_phys:
99      - add some diagnostics for Short-wave and for convection S/R.
100    o pkg/seaice/seaice_growth:
101      - fix a bug in the lateral melt parameterization for SEAICE_ITD
102        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
103      - rearrange loop order for better vector code in the same code block
104      - rewrite the floeDiameter formula to have fewer divisions
105      -  (miraculously) none of this changes the results of seaice_itd
106    o pkg/smooth:
107      - move param smooth2Ddiffnbt to pkg/ecco
108    o pkg/salt_plume:
109      - salt_plume_frac.F:
110         clean up local param names
111         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
112    o pkg/rw:
113      - add RS version of S/R READ_MFLDS_LEV.
114    o pkg/streamice:
115      - fix the restart test by writing/reading pickup_streamice files.
116    o pkg/seaice:
117      - refine checks for jfnk-related parameters
118      - comment out if statement with SEAICEuseIMEX parameter as long as there
119        is no IMEX code to avoid confusion and surprises
120    
121    checkpoint64u (2014/03/07)
122    o verification/MLAdjust:
123      - rename secondary test suffix:
124         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
125         0.leithD -> AhFlxF  + switch to flux-form
126         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
127         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
128    o pkg/mom_vecinv:
129      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
130        to be before mom_calc_visc.F)
131      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
132      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
133        this is simpler for the adjoint and for diagnostics.
134    o model/src + pkg/momentum:
135      - add input files for  2-D additional Western and Southern cell-edge wall
136         (e.g., to add "thin-wall" where it is =1).
137      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
138        using 2nd hFacZ that is computed from initial (fix domain) hFac
139      - known limitations of thin wall implementation: not yet coded for sigma
140        coords; not working with CD-scheme neither.
141    o pkg/seaice:
142      - rename recently introduced parameters from (wrong name) AB to
143        BDF (backward difference time discretisation)
144      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
145    o tools/adjoint_options:
146      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
147    
148    checkpoint64t (2014/02/01)
149    o pkg/ecco
150      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
151        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
152      - replace hard-coded record number and period which only work for monthly
153        with read-in runtime param that works for other periods (month,day,year)
154    o pkg/thsice
155      - corrected store directive fixes thsice adjoint gradient checks
156    o genmake2 & testreport:
157      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
158        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
159        Update testreport accordingly. No need to set "export OPENAD=true"
160        in adjoint_options/adjoint_oad anymore (will be removed later).
161    o pkg/shelfice:
162      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
163        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
164        so that surface forcing applies to k=kSurf if using pkg/shelfice.
165    o pkg/ctrl, pkg/grdchk, pkg/ecco:
166      - Changes to make GENARR more modular (i.e. invisible if not used)
167    o model/src/temp_integrate.F and salt_integrate.F
168      - re-include store directives that were removed on Dec 27th.
169    o model/src/external_forcing_surf.F
170      - add storage directives for EmPmR and PmEpR to avoid recomputation of
171        seaice_model in the adjoint that is problematic when seaice_model is
172        turned off in the adjoint. The resolved issue dated back to July when
173        EXTERNAL_FORCING_SURF call was moved.
174        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
175    o pkg/exf/exf_check.F
176      - fix a small bug again (originally found by Wentao Liu, now found again)
177      - streamline error output
178    o pkg/streamice and aim_v23:
179      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
180        Apple's /usr/bin/cpp knows what to do:
181        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
182        Target: x86_64-apple-darwin13.0.0
183    
184    checkpoint64s (2014/01/05)
185    o tools/adjoint_options:
186      - switch to fastopt.net TAF server (instead of default fastopt.de) for
187        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
188    o model/src:
189      - remove some unnecessary TAF storage directives in forward_step.F and
190        in dynamics.F (note: not always removed by TAF, e.g., double storage
191        of kappaRU,kappaRV in former version of dynamics.F).
192    o model/src & pkg/ptracers:
193      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
194        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
195        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
196      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
197      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
198      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
199    o useSingleCpuInput separates single-CPU input from single-CPU output;
200        for now only implemented for in exf_interp_read.F
201    o verification/advect_xy:
202      - fix missing EXCH call in local version of ini_salt.F and update output.
203    o momentum diagnostics:
204      - fix which deltaT is used in Total-Tendency diagnostics.
205      - fix typo in diagnostics for momentum tendency from AB.
206    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
207        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
208    
209    checkpoint64r (2013/12/08)
210    o verification/*/results:
211      - Update reference output of experiments that were passing with just 13 digits
212         (make it easier to detect future changes in results)
213    o model/src & pkg/ptracers:
214      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
215        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
216        to inside ptracers_integrate.F ; remove ptracers_advection.F
217    o coupling interface pkgs:
218        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
219      - change the config check to test the agreement of Ocean Depth
220        with ATM land/sea mask (instead of ATM orography);
221      - send to coupler the number of coupler time-steps to do for this run:
222        this allows to check for consistency and don't need anymore to be
223        specified in parameter file "data";
224      in coupler:
225      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
226      - improve report to log-file of config setting (pass log-file unit to few S/R)
227    o pkg/compon_communic:
228      - add coupling send/receive for non-tiled integer vector;
229      - add S/R to check and stop if any proc has an error (similar to
230        eesupp/src/stop_if_error.F but single thread and across Comm_World).
231    o pkg/exch2:
232      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
233        through list of all tiles my proc owns.
234    o model/src:
235      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
236        from rTrans) to simplify dependencies (no need to store rTrans anymore in
237        calling S/R); this affects AD results at machine truncation level:
238        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
239        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
240    o tools/build_options:
241      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
242    o coupling interface pkgs:
243        [compon_communic, atm_compon_interf & ocn_compon_interf]
244      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
245        to each S/R that needs it; remove un-used variables.
246      - change component tile registration (cpl_register.F in both compon_interf
247        and mitcomponent_tile_register.F) to pass the full list of tiles
248        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
249      - with pkg/exch2: adopt the same convention used for I/O to define mapping
250        towards coupler global array (unless W2_useE2ioLayOut=F):
251         a) can now use different tiling between atm & ocn comp.
252         b) no needs to modify the run-Off map when changing tiling (was needed
253            even if using the same tiling between atm & ocn).
254         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
255            full land tiles); not yet tested.
256      - check for valid mapping from comp. tile to coupler global array
257      - improve report of tile registration results to log file.
258    o pkg/exch2:
259      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
260        tile-registration (CPL_REGISTER);
261      - activate (un-comment) definition and setting of "W2_tileIndex" list to
262        store the local bi,bj indices of each tile;
263      - also print bi,bj in local report to log file;
264      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
265        Jun 2009 modif of pkg/exch2).
266    o testing on baudelaire:
267      - run 2 tests at a time: no significant slow down (since enough cpu) and
268        get the full set of test done earlier
269      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
270    o model/src/thermodynamics.F and routines called from it:
271      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
272        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
273        velocity (outp) by adding bolus velocity.
274      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
275        mass transport from velocity + lateral grid cell area
276      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
277      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
278     in thermodynamics.F
279      - remove k from thermodynamics.F and move it to temp_integrate.F
280        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
281        loop).
282      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
283        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
284        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
285        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
286      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
287        global_ocean.90x40x15, tutorial_global_oce_biogeo and
288        tutorial_tracer_adjsens (+ TLM output).
289    o tools/OAD_support and (verification/*/) code_oad:
290      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
291        module conversion ; remove unneeded CPP_EEOPTIONS.h.
292      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
293        version (closer to model/inc/CPP_OPTIONS.h).
294    o model/src:
295      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
296        retired list of parameters (routine FREEZE has been replace by surface
297        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
298    o pkg/gmredi:
299      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
300        velocity (same scheme but affects machine truncation) for GM_AdvForm.
301      - update output of FWD experiments: front_relax.bvp,
302        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
303    
304    checkpoint64q (2013/11/17)
305    o verification:
306      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
307        tutorial_global_oce_biogeo and global_ocean.90x40x15.
308      - generate new output (growth & melt) for seaice_itd experiment after
309        updating the input pickup_seaice files (previously wrong).
310    o pkg/cost:
311      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
312        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
313        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
314          cannot be applied to var in common block).
315        o allows to get results independent of tile-per-proc setting (if using
316          slower GLOBAL_SUM_SEND_RECV option).
317      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
318        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
319        forward gradients: update output).
320      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
321        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
322    o pkg/mom_common:
323      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
324        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
325        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
326        ensure that all field value that are used are set.
327    o tutorial_deep_convection (smag3d):
328      - add missing scaling in mom_calc_smag_3d.F;
329      - set smag3D_coeff in input.smag3d such that results do not change.
330    o pkg/dic:
331      - change dic_cost.F to compute cost on each tile first and then apply
332        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
333        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
334      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
335    o eesupp/src & pkg/mdsio:
336      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
337        (from pkg/mdsio) since they are no longer used for tape IO.
338      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
339        (+ keep a copy in pkg/atm_ocn_coupler).
340    o verification/isomip:
341      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
342    o tools/build_options:
343      - optfile linux_amd64_ifort11, fast (no ieee) case:
344        to get a working restart for all experiments, add "-fp-model source"
345        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
346    
347    checkpoint64p (2013/10/20)
348    o pkg/autodiff:
349      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
350        criteria, return to simple (default) tape IO format.
351    o pkg/mdsio (+ eesupp/src):
352      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
353        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
354      - fix globalFile and singleCpuIO options using simpler global mapping.
355      - new pairs of scatter/gather vector S/R (one for each type, generated from
356        template) corresponding to simpler global mapping.
357      - adread_write.F: switch to new S/R (but leave old calls commented) and write
358        to globalFile when parameter globalFiles is set to True.
359      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
360    o pkg/autodiff:
361      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
362        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
363        missing, just add a STOP if array type do not match.
364    o pkg/exf:
365      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
366         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
367         and rename array obsSIce to exf_iceFraction.
368    o tutorial_deep_convection:
369      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
370        for now all in this exp. code dir.
371      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
372        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
373    o eesupp/src:
374      - added SINGLE_DISK_IO option because reading of parameter files on
375        very large number of processors did not work with existing set-up
376    
377    checkpoint64o (2013/09/25)
378    o pkg/atm_phys & atm_compon_interf:
379      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
380    o tools/build_options:
381      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
382        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
383        remove CPP setting (was identical to genmake2 default).
384    o pkg/gmredi & model/src: Some updating and work done on the residual model.
385      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
386      - fixed up the calculation of the eddy stress and how it is added to the
387        external forcing via taueddy_external_forcing.F
388      - at the moment, it is very experimental and only works with the variable eddy
389        diffusivity calculated in gmredi_k3d.F
390    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
391        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
392    o testreport (& tools/do_tst_2+2):
393      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
394    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
395      - remove CPP='cpp -traditional -P' (this is genmake2 default)
396      - add switch (for big setups) to use 'medium' memory-model (but leave it
397        commented out for now). Note: needed with FC 19 to compile big setups.
398    o pkg/atm_compon_interf:
399      - regroup per field origin (model & pkgs) the coupling storage routines
400         (which accumalate in time each coupling field)
401      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
402        update accordingly + simplify aim_do_physics.F
403    
404    checkpoint64n (2013/08/26)
405    o pkg/bbl:
406      - update formulation to reduce dispersion of tracer properties in bbl
407      - replaced horizontal and vertical transport parameters with velocities
408      - changes results for verification/global_with_exf.yearly
409    o verification/halfpipe_streamice:
410      - change to matrix construction; update both Fwd & AD output.
411    o verification/tutorial_tracer_adjsens:
412      - OpenAD test: switch to vector-invariant momentum since fluxform with
413        rStar causes problems with OpenAD; update output.
414    o tools:
415      - genmake2: define a common prefix for all temp-file names ; move them
416        to local /tmp disk (but would be easy to move them back);
417      - xmakedepend: apply the same switch for temp-files.
418    o pkg/offline:
419      - changes for use with rStar (NLFS): assume that we continue to provide
420        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
421        output files) and apply r* scaling at each time-step (function of the time
422        varying Eta field); use normal pickup files (needed for restart with NLFS).
423    o adjoint with OpenAD:
424      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
425        package openad.  This package has to be compiled for all runs with OpenAD
426        instead of specifying code_oad_all as a modification directory.
427      - link the fortran templates from tools/OAD_support to the build directory
428        for preprocessing to avoid conflicts between different setups compiled
429        simultaneously and simplify cleanup.
430    o pkg/exf:
431      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
432        main model or other pkgs are exchanged in EXF_MAPFIELDS).
433    o model/src:
434      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
435        (similar to do_fields_blocking_exchanges.F).
436    o tools/genmake2:
437      - remove TAF output src code just before calling staf (when not doing a fresh
438        built, will stop if things go wrong with staf).
439      - fix target "adobj" (left from TAF version-2 transition)
440    o pkg/diagnostics:
441      - add a parameter to track the status of pkg/diagnostics activation;
442        this replace/extend the use of logical param "settingDiags" (to check
443        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
444        New S/R to print error message and stop when pkgStatus is not right.
445      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
446    
447    checkpoint64m (2013/08/13)
448    o model/inc:
449      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
450        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
451    o pkg/kpp & aim_v23:
452      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
453    o pkg/seaice:
454      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
455        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
456      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
457    o eesupp/src:
458      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
459        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
460    o switch to TAF version-2:
461      - add flow directives to "freeze" naming convention for ad-routines that
462        are used in I/O routines of adjoint state and associated common blocks
463        that are used in adcommon.h (backward compatible with version-1)
464      - update all ad-optfiles (in tools/adjoint_options + few local to some
465        verification exp) to switch to latest TAF version (currently 2.5.5);
466        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
467        out except for diva).
468      - the major change with TAF version-2 is that both the differentiated
469        routines and the forward routines (new) are returned as part of the TAF
470        output source code. Update genmake2 accordingly.
471      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
472        with version-2 when compared to TLM or FWD gradient); other experiments
473        output show minor changes (machine truncation level); update the few AD &
474        TLM output with 12 matching digits only (some prior to version-2 switch).
475    
476    checkpoint64l (2013/08/05)
477    o model/src:
478      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
479      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
480        when using TAF but only if using OpenAD.
481    o pkg/mom_common+fluxform+vecinv:
482      - always set horiz. viscosity arrays to background value before calling
483        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
484        only when using variable horiz. viscosity (useVariableVisc=T);
485      - simplify mom_vecinv.F (only 1 block for momViscosity).
486    o pkg/mom_common: variable horiz. viscosity in NH code
487      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
488        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
489      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
490        useBiharmonicVisc & useVariableVisc.
491      - fix old bug (already in 1rst implementation of variable horizontal viscosity
492        in calc_gw.F, version 1.27, 2006/06/20):
493        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
494        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
495      - change background horiz viscosity in vertical momentum (gW) to always be
496        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
497        any type of variable viscosity, e.g., viscAh/4Grid)
498      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
499        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
500        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
501        default viscAh,viscA4 is zero).
502    o model/src:
503      - extend length of drC & recip_drC from Nr to Nr+1.
504    o Divided Adjoint (DIVA) with MPI:
505      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
506      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
507        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
508    
509    checkpoint64k (2013/07/23)
510    o tools/OAD_support:
511      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
512        and remove it from genmake2.
513    o tools/build_options:
514      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
515        MPI_HEADER_FILES list (let genmake2 find the missing headers)
516    o verification/halfpipe_streamice:
517      - change to driving stress formulation; update both Fwd & AD output.
518    o tools/genmake2 and Divided Adjoint with MPI:
519      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
520      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
521      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
522        Makefile, which is set by genmake2, and check which mpi-headers are needed.
523        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
524      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
525    o testreport:
526      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
527        perform additional runs (number of additional runs is "add_DIVA_runs" taken
528        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
529    o verification/lab_sea (AD test):
530      - change to test Divided Adjoint Run in this set-up (both standard AD test
531        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
532    o pkg atm_ & ocn_compon_interf:
533      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
534        staggerTimeStep implementation) and disable (retired) corresponding
535        parameter.
536    o pkg/offline:
537      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
538      - add S/R OFFLINE_CHECK to print offline parameter summary
539        and stop if loading a file that is not used;
540      - enable to calculate GMRedi tensor, KPP mixing and convective index
541        when the corresponding file(s) is/are not specified (but pkg is used).
542      - comment out resetting of monitorFreq (to endTime) since it still useful
543        for monitoring CFL numbers and checking offline fields.
544    o OpenAD:
545      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
546        smaller standard output) and generate new (smaller) output (on baudelaire
547        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
548    o model/src:
549      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
550        (where external_forcing_adjust was called) and change list of arguments;
551      - merge external_forcing_adjust.F into external_forcing_surf.F
552      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
553        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
554        previously in file "balance_relax.F", now removed); remove corresponding
555        arrays in FFIELDS.h.
556      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
557        a hack for getting back surfaceForcingS (loaded from file) when using
558        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
559      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
560        (was getting only 11 digits for AD-grad, due to different truncation
561         error in AD code).
562    
563    checkpoint64j (2013/07/04)
564    o pkg/offline:
565      - to enable the use of other features with pkg offline (e.g., obcs),
566        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
567      - comment out "allowFreezing" (now active) in 2 offline testing exp.
568    o pkg/exf ALLOW_RUNOFTEMP
569      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
570      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
571      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
572    o pkg/atm_phys:
573      - allows to add some damping on uVel,vVel (strength only function of k).
574    o verification, ad-tests:
575      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
576        global_ocean_ebm and offline_exf_seaice.thsice.
577    o verification/halfpipe_streamice:
578      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
579        flux input boundary conditions to be ignored; a fix for this bug changed
580        verification results for forward test.
581      - add adjoint test.
582    o pkg/ptracers:
583      - allow to restart without SOM pickup (resetting SOM to zero).
584    o pkg/gmredi:
585      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
586      - It uses mixing length theory and suppression by steering level effects to
587        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
588        to JPO, for more details).
589      - It also uses the diffusivity to calculate an eddy induced streamfunction
590        based on a PV closure (rather than a buoyancy closure as in GM).
591      - New files added to pkg/gmredi:
592        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
593          induced overturning streamfunction (called from gmredi_calc_tensor)
594        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
595          for use in gmredi_k3d
596        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
597          the eddy diffusivity
598    
599    checkpoint64i (2013/06/18)
600    o pkg/cheapaml:
601      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
602        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
603        with pkg/cheapaml.
604    o utils/python: add subpackage for cubed sphere function, first example is
605        simple cs.pcol to plot 2D fields on a map
606    o pkg/streamice:
607      - This is a new package in MITgcm, which solves dynamic equations for ice
608         sheets and ice streams
609      - At the moment it is independent of atmosphere/ocean dynamics, or any
610        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
611        ed that this will change)
612      - There is a new verification exercise that tests it, halfpipe_streamice,
613        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
614        rectangular embayment
615      - halfpipe_streamice is forward-only for now, will have TAF test soon
616      - for questions, email dgoldber@mit.edu
617    o pkg/thsice:
618      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
619        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
620      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
621         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
622      - allow precip from pkg/cheapaml to make snow over seaice.
623    o pkg/cfc:
624      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
625      - remove atmos CFC 2-D arrays from common bloc (now local variables)
626      - change some hard-coded constant to run time parameter for reading and
627        and interpolating atmospheric CFC ; keep same default as previously.
628      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
629      - put arguments in standard order: myTime, myIter, myThid
630      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
631        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
632      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
633      - new routine to print summary of CFC params and check for consistency.
634    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
635      similar to thsice_advdiff.
636      Note that for the B-grid case the routine parameters uc/vc are overwritten.
637    o pkg/cfc:
638      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
639        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
640      - fix interpolation of atmphspheric CFC between Sorthern and Northern
641        hemisphere value.
642    o pkg/seaice:
643      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
644    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
645                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
646      - requires an additional time level that is stored in the pickup
647      - you can start with AB2 from a pickup without this time level with
648        pickupStrictlyMatch = .false.
649    
650    checkpoint64h (2013/05/26)
651    o pkg/cheapaml:
652      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
653        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
654      - consistent treatment of uWind,vWind location: assume everywhere in
655        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
656        (Note: was already the case for Tair,Qair advection);
657        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
658      - compute diabatic forcing only in the interior (excluding overlap regions)
659      - fill in array "Qsw" (for short-wave heating);
660      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
661        before any update (consistent with MITgcm state var diagnostics);
662      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
663        non periodic ; + adjusted for uWind,vWind (C-grid).
664    o pkg/seaice:
665      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
666        add explicitly pkg/exf in experiments that currently use pkg/seaice.
667      - allows to compile pkg/seaice without pkg/exf.
668    o tools/OAD_support:
669      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
670        of array "ourStepOf" in function rvNextAction (revolve.F90).
671    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
672      - change pkg name (to be used with other atmospheric physics pkg)
673        but by-pass CVS when making the new pkg so that we keep the CVS history.
674    o pkg/offline:
675      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
676        (previously called from pkg/dic_surfforcing_init.F)
677    o model/src:
678      - re-order sequence of calls within packages_init_variables.F, using
679        standard order, except for:
680         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
681         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
682    o new pkg: atm_phys
683      - add entry point and source code (previously in contrib
684          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
685        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
686      - re-order sequence of calls within packages_readparms.F,
687         packages_init_fixed.F and packages_write_pickup.F
688        (but skip packages_init_variables.F because of TAF issues).
689      - update contrib/*/atm_gray/ experiment.
690    o pkg/seaice (ITD code):
691      - simplify and fix the writing of pickup-files for ITD case
692    o pkg/seaice (ITD code):
693      - introduce floe size dependent lateral melt for ITD case;
694      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
695      - update seaice_itd experiment main output.
696    o pkg/thsice:
697      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
698        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
699        changed accordingly pkg/atm2d.
700    
701    checkpoint64g (2013/05/01)
702    o pkg/exf ALLOW_RUNOFTEMP
703      - if defined,  river and glacier runoff temperature can be read-in from
704        runoftempfile; runoftempfile needs to have same format as runofffile
705    o pkg/thsice (& pkg/bulk_force):
706      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
707        for energy content of Precip + RunOff & Evap (like with pkg/exf).
708      - change computation domain to always be the interior (without overlap).
709      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
710    o verification/tutorial_global_oce_biogeo:
711      - add preliminary OpenAD setup (still has problems)
712    o pkg/seaice:
713      - turn some parameters for choosing the convergence criterion of
714        the inexact Newton method (JFNK) into runtime parameters for convenience
715      - clean up seaice_calc_viscosities.F: remove/retire two options for
716        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
717        the results of lab_sea/input because a division has been replaced by
718        a multiplication with the reciprocal (sumNorm)
719      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
720        convergence of solver (changes results, of course), and to test some
721        new features
722    o model/src:
723      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
724      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
725      - move forcing adjustment (balancing surface forcing) in specific S/R
726        where might also be applied exchanges (if needed) to forcing arrays.
727    o pkg/shelfice:
728      - allow to specify the Ice-Shelf mass per unit area (instead of
729        shelficeLoadAnomaly) and do the conversion from one to the other
730      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
731        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
732        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
733        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
734      - update isomip experiment forward output (get machine truncation error
735        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
736    o verification/offline_exf_seaice:
737      revise data.seaice in input.thermo and input_ad and update results accordingly
738        HO = 0.2, SEAICE_areaLossFormula = 2,
739        SEAICE_growMeltByConv = .TRUE.,
740        SEAICE_doOpenWaterMelt = .TRUE.,
741      Improve consistency with input.thsice and fix the spurious 500m ice corners
742    o verification/global_ocean.cs32x15:
743      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
744        in icedyn (thsice+seaice-dyn) test and update output.
745    o verification/offline_exf_seaice:
746      - adjust list of tested variables (with testreport) and update
747        standard test output with better slection of monitored fields.
748    o pkg/cd_code:
749      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
750        experiment lab_sea.hb87
751    o tools/genmake2:
752      - change default makedepend from the system default to tools/xmakedepend:
753        When no makedepend is specified, select tools/xmakedepend it the test pass,
754        otherwise select the system default (if exist and pass the test) or
755        try to build cyrus-makedepend ; stop if none of the 3 works.
756    o pkg/exf & pkg/thsice:
757      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
758        for energy content of Precip + RunOff & Evap. Assumes:
759       1) Rain has same temp as Air.
760       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
761       3) Run-Off comes at the temp of surface water (with same Cp)
762       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
763        put directly into Latent Heat flux & should use water-vapor heat capacity.
764       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
765        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
766    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
767        (compile when SEAICE_ALLOW_JFNK is defined)
768    o pkg/thsice:
769      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
770        implementation): move THSICE_AVE call after the advection (called directly
771        from thsice_do_advect.F).
772    o verification/global_ocean.90x40x15 and OpenAD:
773      New experiment for OpenAD is identical to the one in input_ad except that
774        multiDimAdvection=.FALSE.,
775      There is still an issue with this.
776    o pkg/thsice:
777      - account for ice velocity (ocean relative velocity) in turbulent heat flux
778        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
779        and offline_exf_seaice (main test).
780    
781    checkpoint64f (2013/03/31)
782    o verification/OpenAD:
783      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
784    o verification/isomip, pkg/shelfice and OpenAD:
785      - add OpenAD setup to this exp and make shelfice package work with OpenAD
786    o verification/tutorial_global_oce_biogeo:
787      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
788    o verification/offline_exf_seaice:
789      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
790    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
791      - add OpenAD setup to this exp and make ptracers package work with OpenAD
792    o pkg/seaice/seaice_evp.F:
793       mask the asymmetric contribution of the ice-ocean stress (when
794       the turningAngle is non-zero) over open water to avoid stripes
795       in the EVP-solutions after many EVP-substeps. This does not change
796       the verification experiment (because turningAngle=0 in that experiment),
797       but will affect other EVP solutions with turningAngle.ne.0
798    o verification, AD & TLM output:
799      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
800        additions and multiplications which affect results at machine truncation
801        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
802        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
803        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
804        digits of matching.
805    o pkg/seaice:
806       modify lsr-algorithm so that it vectorizes AND converges by using a
807       "zebra" method: split vector loop into two with step size 2; this
808       solves a general convergence problem for the JFNK solver on a vector
809       computer. It has the potential to even improve convergence for
810       non-vector machines, but it does change the results so it is turned
811       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
812       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
813    
814    checkpoint64e (2013/03/05)
815    o pkg/ecco and several verification experiments:
816       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
817       from ecco package, and revert to unified routine in model/src/
818       Adjust verification experiments accordingly, especially gloal_oce_llc90
819       Should conclude long-standing work by Gael to reconsile the_main_loop with
820       ECCO and will enable OpenAD's revolve loop in ECCO setup.
821    o pkg/generic_advdiff:
822      - implement compressible flow method for multi-dim advection (similar to
823        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
824        TAF generates many recomputations) to use it; no yet coded with implicit
825        vertical advection.
826      - change experiment advect_cs (new output) and advect_xy (same output)
827        to test compressible flow multi-dim advection.
828    o pkg/generic_advdiff:
829      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
830        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
831    o pkg/seaice:
832      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
833        bug affects two verification experiments (lab_sea and lab_sea.hb87),
834        recover old (wrong) results by setting noSlipFac = 2. in
835        seaice_calc_strainrates.F;
836      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
837      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
838        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
839      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
840    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
841      - new subroutines seaice_lsr_tridiagu/v
842      - introduce loop bounds i/jmin/max to be able to use a restricted
843        additive Schwarz method, but not used for now.
844      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
845      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
846    o OpenAD support
847       Reorganize S/R call for overall time-stepping loop to facilitate
848       OpenAD revolve loop replacement
849       (new S/R main_do_loop.F)
850    o model/src:
851      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
852      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
853        ADAMS_BASHFORTH2.
854    o pkg/cheapaml:
855      - add new parameter (default=F, same as before) to disable full domain
856        (including land) periodicity in X & Y dir.
857      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
858        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
859        into single S/R CHEAPAML_TIMESTEP.
860    
861    checkpoint64d (2013/02/17)
862    o pkg/monitor (angular momentum):
863      - do not add Eta contribution to the total AM if using rigid-lid;
864      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
865      - horizontal discretisation: compute Zonal wind contribution separately for
866        each component (instead of from cell centered averaged) and use the 4
867        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
868      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
869        FreeSurf) if using vectorInvariant momentum.
870    o model/src (horizontal grid):
871      - move initialisation of all horizontal grid arrays to null value
872        from specific horizontal grid S/R to main S/R INI_GRID;
873      - add 2 new arrays to project model C-grid velocity on to zonal direction
874        (similar to AngleCosC & -AngleSinC but at U and V point location) and
875        compute them in S/R CALC_GRID_ANGLES.
876    o pkg/seaice: replace a hard coded parameter by a runtime parameter
877        SEAICE_JFNK_tolIter
878    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
879        preconditioner for JFNK (run LSR into the overlaps as far as possible,
880        i.e OLx/y-2, but overwrite the solution in the overlaps)
881      - extend loop range in seaice_calc_viscosity
882      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
883      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
884      - slightly modify loops in tridiagonal solver lsr-preconditioner
885      - by default remove the extra exchange in seaice_preconditioner with a
886        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
887      - modify offline_exf_seaice so that old results without RAS are reproduced
888        for output.dyn_jfnk.txt
889      in seaice_fgmres.F (unrelated to RAS)
890      - add a cpp-flag option for a re-ordered mapping (potentially more
891        efficient), but because this changes the results, turn it off by
892        default
893      - replace the save statement by local common blocks
894    o utils/matlab:
895      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
896      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
897        instead of local script "load_cs.m".
898    o pkg/seaice:
899      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
900        to the scalarProductMetric and the unrolling. By chance this does not
901        change the verification experiment, because of the particular domain
902        decomposition
903    o pkg/diagnostics:
904      - change default missing_value from UNSET_RL to -999.
905    o pkg/layers: improve vectorization of layers_fluxcalc.F
906      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
907        time spent in this routine by more than a factor of 3 on an NEC-SX8
908      - step 2: replace search algorithm by a bisection algorithm found in
909        Press et al. Numerical Recipes in Fortran. This algorithm can be
910        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
911        For now, use this algorithm only for TARGET_NEC_SX defined.
912      - moved the search algorithm into a separate subroutine, that is kept
913        within the same file for automatic inlining.
914      - modified catching potential errors
915    o pkg/ecco:
916      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
917    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
918      - modifications for ALLOW_GENTIM2D_CONTROL
919      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
920      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
921      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
922      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
923    o model/src:
924      - account for moist thermodynamics in (dry) potential temperature equation;
925        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
926        and cpl_aim+ocn.
927      - also switch to standard compiler (gfortran, was using ifort previously)
928        for fizhi-cs experiments reference output.
929    o pkg/ctrl:
930      - 1st step toward generic time-varying control variable (2D) via CPP option
931        ALLOW_GENTIM2D_CONTROL
932      - note new namelist ctrl_nml_genarr in data.ctrl
933    o verification/global_ocean.cs32x15:
934      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
935        thsice calling sequence and update "output.icedyn.txt" output file.
936    o pkg/ptracers:
937      - from Ryan A.: code to allow to restart a tracer at regular time interval
938        specifying a reset frequency and a reset-phase (for each tracers).
939    o pkg/thsice:
940      - implement new sequence of calls for thsice+seaice:
941          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
942          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
943      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
944        in CPP_OPTIONS.h) to recover old sequence;
945      - update diagnostics for Intermediate State thsice diagnostics: now filled
946        just before advection (instead of just after advection in old sequence);
947      - update output of experiment offline_exf_seaice (standard test);
948      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
949        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
950    o pkg/aim_v23:
951      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
952      - use standard pkg/mdsio routines to read & write CO2 pickup file;
953      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
954      - Implement new sequence of calls for seaice advection (with thsice and
955        seaice diffusion): do ice advection after ice-Thermodynamic (previously
956        was done before); change aim_do_physics.F (split the bi,bj loops block);
957      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
958    o pkg/thsice:
959      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
960        where just seaice diffusion is used without seaice-dynamics.
961    
962  checkpoint64c (2013/01/18)  checkpoint64c (2013/01/18)
963  o pkg/seaice:  o pkg/seaice:
964    - add a parameter JFNKres_tFac that can replace JFNKres_t    - add a parameter JFNKres_tFac that can replace JFNKres_t
