4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
8        not used right now, but can be used in BGC packages to fix conservation.
9    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
10        other packages too.
11    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
12       SEAICE_rhoIce in the Rothrock (1975)-type strength calculations
13       (bug fix)
14    o model/src:
15      - since we have several heat capacity (even in model/src), define "recip_Cp"
16        as local variable (no longer in common block) to avoid any confusion.
17      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
18    o pkg/exf:
19      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
20        air density as function of air Temp, Humidity and atm pressure.
21    
22    checkpoint64w (2014/05/02)
23    o verification:
24      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
25        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
26        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
27        affects AD gradient (down to 8-7 matching digits for global_ocean and
28        5-6 for lab_sea).
29    seaice_reg_ridge.F seaice_do_ridging.F
30    o model/src: for atmosphere in p* coords:
31      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
32      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
33        but not yet activated.
34    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
35      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
36      - this changes the results (but not for any verification experiment, because
37        none tests this), but avoids having an extra field in the restart files
38    o pkg/seaice: remove global variable TICE (not needed)
39      - replace by TICES or local variable where necessary (cost_seaice_test,
40        seaice_diagnostics_state)
41      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
42      - use specific read/write routines for reading and writing individual leves
43        of a multilevel field
44    o pkg/ctrl & model/inc:
45      - move additional anomaly fields of control vars (related to options:
46         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
47        from DYNVARS.h into new header file: CTRL_FIELDS.h
48    o pkg/seaice: some small modifications to the ridging code
49      - make fw2ObyRidge a global variable and add the freshwater flux to
50        seaice_growth
51      - pass actual thickness from seaice_prepare_ridging, so that it is
52        computed only in one place and compute it in the same way as in
53        seaice_growth
54      - initialise more fields in seaice_do_ridging that where cause floating
55        point exceptions over land
56    o pkg/seaice: preparations for ridging code and first real ridging code
57      - move most of "PART 1" of S/R seaice_growth into a new and separate
58        S/R seaice_reg_ridge that will both regularize the state variable after
59        advection call the actual ridging routine;
60      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
61        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
62      - remove ridging code from seaice_advdiff
63      - clean up remaining part 1 of seaice_growth in an attempt to make it
64        more readable (this is probably subjective)
65      - call seaice_itd_redist once in the initialisation phase to have the initial
66        conditions in the correct category
67      - finally: add new ridging routine for ITD code
68    
69    checkpoint64v (2014/04/11)
70    o pkg/ecco:
71      - add runtime parameters mdt[start,end]date[1,2]
72      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
73    o pkg/seaice:
74      - make deltaC a global variable, so that it can be used in ridging code
75      - first step towards ridging: introduce new routines that compute
76        ice strength based on ridging parameters
77      - add diagnostic for HSNOWITD
78      - add opnWtrFrac as a global variable (required for ridging scheme)
79    o pkg/salt_plume + pkg/seaice/seaice_growth.F
80      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
81        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
82    o verification/hs94.1x64x5:
83      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
84      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
85    o autodiff:
86      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
87        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
88        For now, only in pkgs used in verification/hs94.1x64x5.
89      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
90        which are specific to TAF/TAMC).
91      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
92        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
93        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
94      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
95        building mitgcmuv_ad (make adAll).
96    o pkg/ecco:
97      - cost_gencost_seaicev4.F:
98         reformulate proxy cost as function of sst and local param SEAICE_freeze
99         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
100      - add stop statement if old names siv4-[sst,vol] are used
101      - add snapshots + cost reports for atmospheric longwave
102      - remove factor 0.1 in front of wtau[u,v]
103      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
104         ALLOW_TMI_SST_COST_CONTRIBUTION
105    o pkg/atm_phys:
106      - add some diagnostics for Short-wave and for convection S/R.
107    o pkg/seaice/seaice_growth:
108      - fix a bug in the lateral melt parameterization for SEAICE_ITD
109        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
110      - rearrange loop order for better vector code in the same code block
111      - rewrite the floeDiameter formula to have fewer divisions
112      -  (miraculously) none of this changes the results of seaice_itd
113    o pkg/smooth:
114      - move param smooth2Ddiffnbt to pkg/ecco
115    o pkg/salt_plume:
116      - salt_plume_frac.F:
117         clean up local param names
118         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
119    o pkg/rw:
120      - add RS version of S/R READ_MFLDS_LEV.
121    o pkg/streamice:
122      - fix the restart test by writing/reading pickup_streamice files.
123    o pkg/seaice:
124      - refine checks for jfnk-related parameters
125      - comment out if statement with SEAICEuseIMEX parameter as long as there
126        is no IMEX code to avoid confusion and surprises
127    
128    checkpoint64u (2014/03/07)
129    o verification/MLAdjust:
130      - rename secondary test suffix:
131         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
132         0.leithD -> AhFlxF  + switch to flux-form
133         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
134         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
135    o pkg/mom_vecinv:
136      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
137        to be before mom_calc_visc.F)
138      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
139      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
140        this is simpler for the adjoint and for diagnostics.
141    o model/src + pkg/momentum:
142      - add input files for  2-D additional Western and Southern cell-edge wall
143         (e.g., to add "thin-wall" where it is =1).
144      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
145        using 2nd hFacZ that is computed from initial (fix domain) hFac
146      - known limitations of thin wall implementation: not yet coded for sigma
147        coords; not working with CD-scheme neither.
148    o pkg/seaice:
149      - rename recently introduced parameters from (wrong name) AB to
150        BDF (backward difference time discretisation)
151      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
152    o tools/adjoint_options:
153      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
154    
155    checkpoint64t (2014/02/01)
156    o pkg/ecco
157      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
158        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
159      - replace hard-coded record number and period which only work for monthly
160        with read-in runtime param that works for other periods (month,day,year)
161    o pkg/thsice
162      - corrected store directive fixes thsice adjoint gradient checks
163    o genmake2 & testreport:
164      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
165        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
166        Update testreport accordingly. No need to set "export OPENAD=true"
167        in adjoint_options/adjoint_oad anymore (will be removed later).
168    o pkg/shelfice:
169      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
170        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
171        so that surface forcing applies to k=kSurf if using pkg/shelfice.
172    o pkg/ctrl, pkg/grdchk, pkg/ecco:
173      - Changes to make GENARR more modular (i.e. invisible if not used)
174    o model/src/temp_integrate.F and salt_integrate.F
175      - re-include store directives that were removed on Dec 27th.
176    o model/src/external_forcing_surf.F
177      - add storage directives for EmPmR and PmEpR to avoid recomputation of
178        seaice_model in the adjoint that is problematic when seaice_model is
179        turned off in the adjoint. The resolved issue dated back to July when
180        EXTERNAL_FORCING_SURF call was moved.
181        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
182    o pkg/exf/exf_check.F
183      - fix a small bug again (originally found by Wentao Liu, now found again)
184      - streamline error output
185    o pkg/streamice and aim_v23:
186      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
187        Apple's /usr/bin/cpp knows what to do:
188        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
189        Target: x86_64-apple-darwin13.0.0
190    
191    checkpoint64s (2014/01/05)
192    o tools/adjoint_options:
193      - switch to fastopt.net TAF server (instead of default fastopt.de) for
194        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
195    o model/src:
196      - remove some unnecessary TAF storage directives in forward_step.F and
197        in dynamics.F (note: not always removed by TAF, e.g., double storage
198        of kappaRU,kappaRV in former version of dynamics.F).
199    o model/src & pkg/ptracers:
200      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
201        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
202        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
203      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
204      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
205      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
206    o useSingleCpuInput separates single-CPU input from single-CPU output;
207        for now only implemented for in exf_interp_read.F
208    o verification/advect_xy:
209      - fix missing EXCH call in local version of ini_salt.F and update output.
210    o momentum diagnostics:
211      - fix which deltaT is used in Total-Tendency diagnostics.
212      - fix typo in diagnostics for momentum tendency from AB.
213    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
214        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
215    
216    checkpoint64r (2013/12/08)
217    o verification/*/results:
218      - Update reference output of experiments that were passing with just 13 digits
219         (make it easier to detect future changes in results)
220    o model/src & pkg/ptracers:
221      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
222        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
223        to inside ptracers_integrate.F ; remove ptracers_advection.F
224    o coupling interface pkgs:
225        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
226      - change the config check to test the agreement of Ocean Depth
227        with ATM land/sea mask (instead of ATM orography);
228      - send to coupler the number of coupler time-steps to do for this run:
229        this allows to check for consistency and don't need anymore to be
230        specified in parameter file "data";
231      in coupler:
232      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
233      - improve report to log-file of config setting (pass log-file unit to few S/R)
234    o pkg/compon_communic:
235      - add coupling send/receive for non-tiled integer vector;
236      - add S/R to check and stop if any proc has an error (similar to
237        eesupp/src/stop_if_error.F but single thread and across Comm_World).
238    o pkg/exch2:
239      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
240        through list of all tiles my proc owns.
241    o model/src:
242      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
243        from rTrans) to simplify dependencies (no need to store rTrans anymore in
244        calling S/R); this affects AD results at machine truncation level:
245        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
246        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
247    o tools/build_options:
248      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
249    o coupling interface pkgs:
250        [compon_communic, atm_compon_interf & ocn_compon_interf]
251      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
252        to each S/R that needs it; remove un-used variables.
253      - change component tile registration (cpl_register.F in both compon_interf
254        and mitcomponent_tile_register.F) to pass the full list of tiles
255        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
256      - with pkg/exch2: adopt the same convention used for I/O to define mapping
257        towards coupler global array (unless W2_useE2ioLayOut=F):
258         a) can now use different tiling between atm & ocn comp.
259         b) no needs to modify the run-Off map when changing tiling (was needed
260            even if using the same tiling between atm & ocn).
261         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
262            full land tiles); not yet tested.
263      - check for valid mapping from comp. tile to coupler global array
264      - improve report of tile registration results to log file.
265    o pkg/exch2:
266      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
267        tile-registration (CPL_REGISTER);
268      - activate (un-comment) definition and setting of "W2_tileIndex" list to
269        store the local bi,bj indices of each tile;
270      - also print bi,bj in local report to log file;
271      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
272        Jun 2009 modif of pkg/exch2).
273    o testing on baudelaire:
274      - run 2 tests at a time: no significant slow down (since enough cpu) and
275        get the full set of test done earlier
276      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
277    o model/src/thermodynamics.F and routines called from it:
278      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
279        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
280        velocity (outp) by adding bolus velocity.
281      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
282        mass transport from velocity + lateral grid cell area
283      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
284      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
285     in thermodynamics.F
286      - remove k from thermodynamics.F and move it to temp_integrate.F
287        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
288        loop).
289      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
290        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
291        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
292        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
293      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
294        global_ocean.90x40x15, tutorial_global_oce_biogeo and
295        tutorial_tracer_adjsens (+ TLM output).
296    o tools/OAD_support and (verification/*/) code_oad:
297      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
298        module conversion ; remove unneeded CPP_EEOPTIONS.h.
299      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
300        version (closer to model/inc/CPP_OPTIONS.h).
301    o model/src:
302      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
303        retired list of parameters (routine FREEZE has been replace by surface
304        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
305    o pkg/gmredi:
306      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
307        velocity (same scheme but affects machine truncation) for GM_AdvForm.
308      - update output of FWD experiments: front_relax.bvp,
309        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
310    
311    checkpoint64q (2013/11/17)
312    o verification:
313      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
314        tutorial_global_oce_biogeo and global_ocean.90x40x15.
315      - generate new output (growth & melt) for seaice_itd experiment after
316        updating the input pickup_seaice files (previously wrong).
317    o pkg/cost:
318      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
319        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
320        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
321          cannot be applied to var in common block).
322        o allows to get results independent of tile-per-proc setting (if using
323          slower GLOBAL_SUM_SEND_RECV option).
324      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
325        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
326        forward gradients: update output).
327      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
328        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
329    o pkg/mom_common:
330      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
331        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
332        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
333        ensure that all field value that are used are set.
334    o tutorial_deep_convection (smag3d):
335      - add missing scaling in mom_calc_smag_3d.F;
336      - set smag3D_coeff in input.smag3d such that results do not change.
337    o pkg/dic:
338      - change dic_cost.F to compute cost on each tile first and then apply
339        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
340        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
341      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
342    o eesupp/src & pkg/mdsio:
343      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
344        (from pkg/mdsio) since they are no longer used for tape IO.
345      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
346        (+ keep a copy in pkg/atm_ocn_coupler).
347    o verification/isomip:
348      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
349    o tools/build_options:
350      - optfile linux_amd64_ifort11, fast (no ieee) case:
351        to get a working restart for all experiments, add "-fp-model source"
352        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
353    
354    checkpoint64p (2013/10/20)
355    o pkg/autodiff:
356      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
357        criteria, return to simple (default) tape IO format.
358    o pkg/mdsio (+ eesupp/src):
359      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
360        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
361      - fix globalFile and singleCpuIO options using simpler global mapping.
362      - new pairs of scatter/gather vector S/R (one for each type, generated from
363        template) corresponding to simpler global mapping.
364      - adread_write.F: switch to new S/R (but leave old calls commented) and write
365        to globalFile when parameter globalFiles is set to True.
366      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
367    o pkg/autodiff:
368      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
369        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
370        missing, just add a STOP if array type do not match.
371    o pkg/exf:
372      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
373         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
374         and rename array obsSIce to exf_iceFraction.
375    o tutorial_deep_convection:
376      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
377        for now all in this exp. code dir.
378      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
379        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
380    o eesupp/src:
381      - added SINGLE_DISK_IO option because reading of parameter files on
382        very large number of processors did not work with existing set-up
383    
384    checkpoint64o (2013/09/25)
385    o pkg/atm_phys & atm_compon_interf:
386      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
387    o tools/build_options:
388      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
389        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
390        remove CPP setting (was identical to genmake2 default).
391    o pkg/gmredi & model/src: Some updating and work done on the residual model.
392      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
393      - fixed up the calculation of the eddy stress and how it is added to the
394        external forcing via taueddy_external_forcing.F
395      - at the moment, it is very experimental and only works with the variable eddy
396        diffusivity calculated in gmredi_k3d.F
397    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
398        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
399    o testreport (& tools/do_tst_2+2):
400      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
401    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
402      - remove CPP='cpp -traditional -P' (this is genmake2 default)
403      - add switch (for big setups) to use 'medium' memory-model (but leave it
404        commented out for now). Note: needed with FC 19 to compile big setups.
405    o pkg/atm_compon_interf:
406      - regroup per field origin (model & pkgs) the coupling storage routines
407         (which accumalate in time each coupling field)
408      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
409        update accordingly + simplify aim_do_physics.F
410    
411    checkpoint64n (2013/08/26)
412    o pkg/bbl:
413      - update formulation to reduce dispersion of tracer properties in bbl
414      - replaced horizontal and vertical transport parameters with velocities
415      - changes results for verification/global_with_exf.yearly
416    o verification/halfpipe_streamice:
417      - change to matrix construction; update both Fwd & AD output.
418    o verification/tutorial_tracer_adjsens:
419      - OpenAD test: switch to vector-invariant momentum since fluxform with
420        rStar causes problems with OpenAD; update output.
421    o tools:
422      - genmake2: define a common prefix for all temp-file names ; move them
423        to local /tmp disk (but would be easy to move them back);
424      - xmakedepend: apply the same switch for temp-files.
425    o pkg/offline:
426      - changes for use with rStar (NLFS): assume that we continue to provide
427        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
428        output files) and apply r* scaling at each time-step (function of the time
429        varying Eta field); use normal pickup files (needed for restart with NLFS).
430    o adjoint with OpenAD:
431      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
432        package openad.  This package has to be compiled for all runs with OpenAD
433        instead of specifying code_oad_all as a modification directory.
434      - link the fortran templates from tools/OAD_support to the build directory
435        for preprocessing to avoid conflicts between different setups compiled
436        simultaneously and simplify cleanup.
437    o pkg/exf:
438      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
439        main model or other pkgs are exchanged in EXF_MAPFIELDS).
440    o model/src:
441      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
442        (similar to do_fields_blocking_exchanges.F).
443    o tools/genmake2:
444      - remove TAF output src code just before calling staf (when not doing a fresh
445        built, will stop if things go wrong with staf).
446      - fix target "adobj" (left from TAF version-2 transition)
447    o pkg/diagnostics:
448      - add a parameter to track the status of pkg/diagnostics activation;
449        this replace/extend the use of logical param "settingDiags" (to check
450        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
451        New S/R to print error message and stop when pkgStatus is not right.
452      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
453    
454    checkpoint64m (2013/08/13)
455    o model/inc:
456      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
457        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
458    o pkg/kpp & aim_v23:
459      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
460    o pkg/seaice:
461      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
462        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
463      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
464    o eesupp/src:
465      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
466        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
467    o switch to TAF version-2:
468      - add flow directives to "freeze" naming convention for ad-routines that
469        are used in I/O routines of adjoint state and associated common blocks
470        that are used in adcommon.h (backward compatible with version-1)
471      - update all ad-optfiles (in tools/adjoint_options + few local to some
472        verification exp) to switch to latest TAF version (currently 2.5.5);
473        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
474        out except for diva).
475      - the major change with TAF version-2 is that both the differentiated
476        routines and the forward routines (new) are returned as part of the TAF
477        output source code. Update genmake2 accordingly.
478      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
479        with version-2 when compared to TLM or FWD gradient); other experiments
480        output show minor changes (machine truncation level); update the few AD &
481        TLM output with 12 matching digits only (some prior to version-2 switch).
482    
483    checkpoint64l (2013/08/05)
484    o model/src:
485      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
486      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
487        when using TAF but only if using OpenAD.
488    o pkg/mom_common+fluxform+vecinv:
489      - always set horiz. viscosity arrays to background value before calling
490        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
491        only when using variable horiz. viscosity (useVariableVisc=T);
492      - simplify mom_vecinv.F (only 1 block for momViscosity).
493    o pkg/mom_common: variable horiz. viscosity in NH code
494      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
495        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
496      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
497        useBiharmonicVisc & useVariableVisc.
498      - fix old bug (already in 1rst implementation of variable horizontal viscosity
499        in calc_gw.F, version 1.27, 2006/06/20):
500        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
501        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
502      - change background horiz viscosity in vertical momentum (gW) to always be
503        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
504        any type of variable viscosity, e.g., viscAh/4Grid)
505      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
506        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
507        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
508        default viscAh,viscA4 is zero).
509    o model/src:
510      - extend length of drC & recip_drC from Nr to Nr+1.
511    o Divided Adjoint (DIVA) with MPI:
512      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
513      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
514        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
515    
516    checkpoint64k (2013/07/23)
517    o tools/OAD_support:
518      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
519        and remove it from genmake2.
520    o tools/build_options:
521      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
522        MPI_HEADER_FILES list (let genmake2 find the missing headers)
523    o verification/halfpipe_streamice:
524      - change to driving stress formulation; update both Fwd & AD output.
525    o tools/genmake2 and Divided Adjoint with MPI:
526      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
527      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
528      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
529        Makefile, which is set by genmake2, and check which mpi-headers are needed.
530        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
531      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
532    o testreport:
533      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
534        perform additional runs (number of additional runs is "add_DIVA_runs" taken
535        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
536    o verification/lab_sea (AD test):
537      - change to test Divided Adjoint Run in this set-up (both standard AD test
538        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
539    o pkg atm_ & ocn_compon_interf:
540      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
541        staggerTimeStep implementation) and disable (retired) corresponding
542        parameter.
543    o pkg/offline:
544      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
545      - add S/R OFFLINE_CHECK to print offline parameter summary
546        and stop if loading a file that is not used;
547      - enable to calculate GMRedi tensor, KPP mixing and convective index
548        when the corresponding file(s) is/are not specified (but pkg is used).
549      - comment out resetting of monitorFreq (to endTime) since it still useful
550        for monitoring CFL numbers and checking offline fields.
551    o OpenAD:
552      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
553        smaller standard output) and generate new (smaller) output (on baudelaire
554        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
555    o model/src:
556      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
557        (where external_forcing_adjust was called) and change list of arguments;
558      - merge external_forcing_adjust.F into external_forcing_surf.F
559      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
560        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
561        previously in file "balance_relax.F", now removed); remove corresponding
562        arrays in FFIELDS.h.
563      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
564        a hack for getting back surfaceForcingS (loaded from file) when using
565        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
566      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
567        (was getting only 11 digits for AD-grad, due to different truncation
568         error in AD code).
569    
570    checkpoint64j (2013/07/04)
571    o pkg/offline:
572      - to enable the use of other features with pkg offline (e.g., obcs),
573        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
574      - comment out "allowFreezing" (now active) in 2 offline testing exp.
575    o pkg/exf ALLOW_RUNOFTEMP
576      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
577      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
578      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
579    o pkg/atm_phys:
580      - allows to add some damping on uVel,vVel (strength only function of k).
581    o verification, ad-tests:
582      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
583        global_ocean_ebm and offline_exf_seaice.thsice.
584    o verification/halfpipe_streamice:
585      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
586        flux input boundary conditions to be ignored; a fix for this bug changed
587        verification results for forward test.
588      - add adjoint test.
589    o pkg/ptracers:
590      - allow to restart without SOM pickup (resetting SOM to zero).
591    o pkg/gmredi:
592      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
593      - It uses mixing length theory and suppression by steering level effects to
594        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
595        to JPO, for more details).
596      - It also uses the diffusivity to calculate an eddy induced streamfunction
597        based on a PV closure (rather than a buoyancy closure as in GM).
598      - New files added to pkg/gmredi:
599        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
600          induced overturning streamfunction (called from gmredi_calc_tensor)
601        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
602          for use in gmredi_k3d
603        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
604          the eddy diffusivity
605    
606    checkpoint64i (2013/06/18)
607    o pkg/cheapaml:
608      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
609        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
610        with pkg/cheapaml.
611    o utils/python: add subpackage for cubed sphere function, first example is
612        simple cs.pcol to plot 2D fields on a map
613    o pkg/streamice:
614      - This is a new package in MITgcm, which solves dynamic equations for ice
615         sheets and ice streams
616      - At the moment it is independent of atmosphere/ocean dynamics, or any
617        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
618        ed that this will change)
619      - There is a new verification exercise that tests it, halfpipe_streamice,
620        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
621        rectangular embayment
622      - halfpipe_streamice is forward-only for now, will have TAF test soon
623      - for questions, email dgoldber@mit.edu
624    o pkg/thsice:
625      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
626        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
627      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
628         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
629      - allow precip from pkg/cheapaml to make snow over seaice.
630    o pkg/cfc:
631      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
632      - remove atmos CFC 2-D arrays from common bloc (now local variables)
633      - change some hard-coded constant to run time parameter for reading and
634        and interpolating atmospheric CFC ; keep same default as previously.
635      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
636      - put arguments in standard order: myTime, myIter, myThid
637      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
638        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
639      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
640      - new routine to print summary of CFC params and check for consistency.
641    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
642      similar to thsice_advdiff.
643      Note that for the B-grid case the routine parameters uc/vc are overwritten.
644    o pkg/cfc:
645      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
646        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
647      - fix interpolation of atmphspheric CFC between Sorthern and Northern
648        hemisphere value.
649    o pkg/seaice:
650      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
651    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
652                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
653      - requires an additional time level that is stored in the pickup
654      - you can start with AB2 from a pickup without this time level with
655        pickupStrictlyMatch = .false.
656    
657    checkpoint64h (2013/05/26)
658    o pkg/cheapaml:
659      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
660        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
661      - consistent treatment of uWind,vWind location: assume everywhere in
662        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
663        (Note: was already the case for Tair,Qair advection);
664        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
665      - compute diabatic forcing only in the interior (excluding overlap regions)
666      - fill in array "Qsw" (for short-wave heating);
667      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
668        before any update (consistent with MITgcm state var diagnostics);
669      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
670        non periodic ; + adjusted for uWind,vWind (C-grid).
671    o pkg/seaice:
672      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
673        add explicitly pkg/exf in experiments that currently use pkg/seaice.
674      - allows to compile pkg/seaice without pkg/exf.
675    o tools/OAD_support:
676      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
677        of array "ourStepOf" in function rvNextAction (revolve.F90).
678    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
679      - change pkg name (to be used with other atmospheric physics pkg)
680        but by-pass CVS when making the new pkg so that we keep the CVS history.
681    o pkg/offline:
682      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
683        (previously called from pkg/dic_surfforcing_init.F)
684    o model/src:
685      - re-order sequence of calls within packages_init_variables.F, using
686        standard order, except for:
687         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
688         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
689    o new pkg: atm_phys
690      - add entry point and source code (previously in contrib
691          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
692        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
693      - re-order sequence of calls within packages_readparms.F,
694         packages_init_fixed.F and packages_write_pickup.F
695        (but skip packages_init_variables.F because of TAF issues).
696      - update contrib/*/atm_gray/ experiment.
697    o pkg/seaice (ITD code):
698      - simplify and fix the writing of pickup-files for ITD case
699    o pkg/seaice (ITD code):
700      - introduce floe size dependent lateral melt for ITD case;
701      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
702      - update seaice_itd experiment main output.
703    o pkg/thsice:
704      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
705        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
706        changed accordingly pkg/atm2d.
707    
708    checkpoint64g (2013/05/01)
709    o pkg/exf ALLOW_RUNOFTEMP
710      - if defined,  river and glacier runoff temperature can be read-in from
711        runoftempfile; runoftempfile needs to have same format as runofffile
712    o pkg/thsice (& pkg/bulk_force):
713      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
714        for energy content of Precip + RunOff & Evap (like with pkg/exf).
715      - change computation domain to always be the interior (without overlap).
716      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
717    o verification/tutorial_global_oce_biogeo:
718      - add preliminary OpenAD setup (still has problems)
719    o pkg/seaice:
720      - turn some parameters for choosing the convergence criterion of
721        the inexact Newton method (JFNK) into runtime parameters for convenience
722      - clean up seaice_calc_viscosities.F: remove/retire two options for
723        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
724        the results of lab_sea/input because a division has been replaced by
725        a multiplication with the reciprocal (sumNorm)
726      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
727        convergence of solver (changes results, of course), and to test some
728        new features
729    o model/src:
730      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
731      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
732      - move forcing adjustment (balancing surface forcing) in specific S/R
733        where might also be applied exchanges (if needed) to forcing arrays.
734    o pkg/shelfice:
735      - allow to specify the Ice-Shelf mass per unit area (instead of
736        shelficeLoadAnomaly) and do the conversion from one to the other
737      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
738        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
739        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
740        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
741      - update isomip experiment forward output (get machine truncation error
742        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
743    o verification/offline_exf_seaice:
744      revise data.seaice in input.thermo and input_ad and update results accordingly
745        HO = 0.2, SEAICE_areaLossFormula = 2,
746        SEAICE_growMeltByConv = .TRUE.,
747        SEAICE_doOpenWaterMelt = .TRUE.,
748      Improve consistency with input.thsice and fix the spurious 500m ice corners
749    o verification/global_ocean.cs32x15:
750      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
751        in icedyn (thsice+seaice-dyn) test and update output.
752    o verification/offline_exf_seaice:
753      - adjust list of tested variables (with testreport) and update
754        standard test output with better slection of monitored fields.
755    o pkg/cd_code:
756      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
757        experiment lab_sea.hb87
758    o tools/genmake2:
759      - change default makedepend from the system default to tools/xmakedepend:
760        When no makedepend is specified, select tools/xmakedepend it the test pass,
761        otherwise select the system default (if exist and pass the test) or
762        try to build cyrus-makedepend ; stop if none of the 3 works.
763    o pkg/exf & pkg/thsice:
764      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
765        for energy content of Precip + RunOff & Evap. Assumes:
766       1) Rain has same temp as Air.
767       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
768       3) Run-Off comes at the temp of surface water (with same Cp)
769       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
770        put directly into Latent Heat flux & should use water-vapor heat capacity.
771       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
772        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
773    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
774        (compile when SEAICE_ALLOW_JFNK is defined)
775    o pkg/thsice:
776      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
777        implementation): move THSICE_AVE call after the advection (called directly
778        from thsice_do_advect.F).
779    o verification/global_ocean.90x40x15 and OpenAD:
780      New experiment for OpenAD is identical to the one in input_ad except that
781        multiDimAdvection=.FALSE.,
782      There is still an issue with this.
783    o pkg/thsice:
784      - account for ice velocity (ocean relative velocity) in turbulent heat flux
785        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
786        and offline_exf_seaice (main test).
787    
788    checkpoint64f (2013/03/31)
789    o verification/OpenAD:
790      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
791    o verification/isomip, pkg/shelfice and OpenAD:
792      - add OpenAD setup to this exp and make shelfice package work with OpenAD
793    o verification/tutorial_global_oce_biogeo:
794      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
795    o verification/offline_exf_seaice:
796      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
797    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
798      - add OpenAD setup to this exp and make ptracers package work with OpenAD
799    o pkg/seaice/seaice_evp.F:
800       mask the asymmetric contribution of the ice-ocean stress (when
801       the turningAngle is non-zero) over open water to avoid stripes
802       in the EVP-solutions after many EVP-substeps. This does not change
803       the verification experiment (because turningAngle=0 in that experiment),
804       but will affect other EVP solutions with turningAngle.ne.0
805    o verification, AD & TLM output:
806      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
807        additions and multiplications which affect results at machine truncation
808        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
809        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
810        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
811        digits of matching.
812    o pkg/seaice:
813       modify lsr-algorithm so that it vectorizes AND converges by using a
814       "zebra" method: split vector loop into two with step size 2; this
815       solves a general convergence problem for the JFNK solver on a vector
816       computer. It has the potential to even improve convergence for
817       non-vector machines, but it does change the results so it is turned
818       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
819       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
820    
821    checkpoint64e (2013/03/05)
822    o pkg/ecco and several verification experiments:
823       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
824       from ecco package, and revert to unified routine in model/src/
825       Adjust verification experiments accordingly, especially gloal_oce_llc90
826       Should conclude long-standing work by Gael to reconsile the_main_loop with
827       ECCO and will enable OpenAD's revolve loop in ECCO setup.
828    o pkg/generic_advdiff:
829      - implement compressible flow method for multi-dim advection (similar to
830        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
831        TAF generates many recomputations) to use it; no yet coded with implicit
832        vertical advection.
833      - change experiment advect_cs (new output) and advect_xy (same output)
834        to test compressible flow multi-dim advection.
835    o pkg/generic_advdiff:
836      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
837        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
838    o pkg/seaice:
839      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
840        bug affects two verification experiments (lab_sea and lab_sea.hb87),
841        recover old (wrong) results by setting noSlipFac = 2. in
842        seaice_calc_strainrates.F;
843      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
844      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
845        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
846      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
847    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
848      - new subroutines seaice_lsr_tridiagu/v
849      - introduce loop bounds i/jmin/max to be able to use a restricted
850        additive Schwarz method, but not used for now.
851      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
852      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
853    o OpenAD support
854       Reorganize S/R call for overall time-stepping loop to facilitate
855       OpenAD revolve loop replacement
856       (new S/R main_do_loop.F)
857    o model/src:
858      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
859      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
860        ADAMS_BASHFORTH2.
861    o pkg/cheapaml:
862      - add new parameter (default=F, same as before) to disable full domain
863        (including land) periodicity in X & Y dir.
864      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
865        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
866        into single S/R CHEAPAML_TIMESTEP.
867    
868    checkpoint64d (2013/02/17)
869    o pkg/monitor (angular momentum):
870      - do not add Eta contribution to the total AM if using rigid-lid;
871      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
872      - horizontal discretisation: compute Zonal wind contribution separately for
873        each component (instead of from cell centered averaged) and use the 4
874        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
875      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
876        FreeSurf) if using vectorInvariant momentum.
877    o model/src (horizontal grid):
878      - move initialisation of all horizontal grid arrays to null value
879        from specific horizontal grid S/R to main S/R INI_GRID;
880      - add 2 new arrays to project model C-grid velocity on to zonal direction
881        (similar to AngleCosC & -AngleSinC but at U and V point location) and
882        compute them in S/R CALC_GRID_ANGLES.
883    o pkg/seaice: replace a hard coded parameter by a runtime parameter
884        SEAICE_JFNK_tolIter
885    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
886        preconditioner for JFNK (run LSR into the overlaps as far as possible,
887        i.e OLx/y-2, but overwrite the solution in the overlaps)
888      - extend loop range in seaice_calc_viscosity
889      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
890      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
891      - slightly modify loops in tridiagonal solver lsr-preconditioner
892      - by default remove the extra exchange in seaice_preconditioner with a
893        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
894      - modify offline_exf_seaice so that old results without RAS are reproduced
895        for output.dyn_jfnk.txt
896      in seaice_fgmres.F (unrelated to RAS)
897      - add a cpp-flag option for a re-ordered mapping (potentially more
898        efficient), but because this changes the results, turn it off by
899        default
900      - replace the save statement by local common blocks
901    o utils/matlab:
902      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
903      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
904        instead of local script "load_cs.m".
905    o pkg/seaice:
906      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
907        to the scalarProductMetric and the unrolling. By chance this does not
908        change the verification experiment, because of the particular domain
909        decomposition
910    o pkg/diagnostics:
911      - change default missing_value from UNSET_RL to -999.
912    o pkg/layers: improve vectorization of layers_fluxcalc.F
913      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
914        time spent in this routine by more than a factor of 3 on an NEC-SX8
915      - step 2: replace search algorithm by a bisection algorithm found in
916        Press et al. Numerical Recipes in Fortran. This algorithm can be
917        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
918        For now, use this algorithm only for TARGET_NEC_SX defined.
919      - moved the search algorithm into a separate subroutine, that is kept
920        within the same file for automatic inlining.
921      - modified catching potential errors
922    o pkg/ecco:
923      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
924    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
925      - modifications for ALLOW_GENTIM2D_CONTROL
926      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
927      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
928      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
929      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
930    o model/src:
931      - account for moist thermodynamics in (dry) potential temperature equation;
932        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
933        and cpl_aim+ocn.
934      - also switch to standard compiler (gfortran, was using ifort previously)
935        for fizhi-cs experiments reference output.
936    o pkg/ctrl:
937      - 1st step toward generic time-varying control variable (2D) via CPP option
938        ALLOW_GENTIM2D_CONTROL
939      - note new namelist ctrl_nml_genarr in data.ctrl
940    o verification/global_ocean.cs32x15:
941      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
942        thsice calling sequence and update "output.icedyn.txt" output file.
943    o pkg/ptracers:
944      - from Ryan A.: code to allow to restart a tracer at regular time interval
945        specifying a reset frequency and a reset-phase (for each tracers).
946    o pkg/thsice:
947      - implement new sequence of calls for thsice+seaice:
948          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
949          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
950      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
951        in CPP_OPTIONS.h) to recover old sequence;
952      - update diagnostics for Intermediate State thsice diagnostics: now filled
953        just before advection (instead of just after advection in old sequence);
954      - update output of experiment offline_exf_seaice (standard test);
955      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
956        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
957    o pkg/aim_v23:
958      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
959      - use standard pkg/mdsio routines to read & write CO2 pickup file;
960      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
961      - Implement new sequence of calls for seaice advection (with thsice and
962        seaice diffusion): do ice advection after ice-Thermodynamic (previously
963        was done before); change aim_do_physics.F (split the bi,bj loops block);
964      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
965    o pkg/thsice:
966      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
967        where just seaice diffusion is used without seaice-dynamics.
968    
969    checkpoint64c (2013/01/18)
970    o pkg/seaice:
971      - add a parameter JFNKres_tFac that can replace JFNKres_t
972        (= JFNKres_tFac*JFNKresidual before JFNK solver)
973      - add a line search option to the JFNK solver
974      - move update of u/vIce and computation of initial residual into a separate
975        routine (same file); makes the code a little easier to read (?)
976      - the line search requires computation of the residual and for some reason
977        I cannot do the update of u/vIce at the beginning of the Newton loop
978        without changing the results, so we move computation of the new residual
979        also to the end of the Newton loop, even without the line search
980    o pkg/mdsio:
981      - write missing value (corresponding to undefined array value) to meta files;
982        skip this if missing value is one (UNSET_RL would be a better value for the
983        case of undefined missing value but it's current the default missing-value);
984        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
985    o pkg/exf & thsice:
986      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
987        diagnostics) even when SHORTWAVE_HEATING is #undef;
988    o verification/cfc_example:
989      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
990        illustrate how to use it).
991    o verification/offline_exf_seaice:
992      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
993        files to only one time-record.
994      in input.thermo: narrow the 2 bands of low initial ice-concentration near
995        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
996        snapshot output; same mcPheePiston value as in thsice with
997        surf-current=0.2m/s.
998      in input.thsice: similar set-up as in input.thermo (channel with same seaice
999        initial conditions).
1000    o verification/cfc_example:
1001      - update file "data" with more standard choice (default rotationPeriod,
1002        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1003        set deltaTFreeSurf to deltaTtracer) and update the output.
1004    o pkg/layers:
1005      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1006      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1007    o verification/offline_exf_seaice:
1008      - set all {field}period to zero for constant-in-time forcing (not tested
1009        anywhere else).
1010    o verification/offline_exf_seaice:
1011      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1012      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1013    o model/src:
1014      - implement Finite-Volume method for (hydrostatic) presure gradient
1015        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1016    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1017      - In order to be compatible with the default EVP code, this requires changing
1018        the EVP code around a little; and because any small change immediately
1019        breaks the lab_sea.hb87 verification experiment, the reference output is
1020        updated two times (each time the remaining aggrement was only 2 digits):
1021        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1022        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1023        The adjoint test lab_sea.evp also needed to be updated.
1024      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1025        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1026        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1027        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1028        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1029        kept obscure, because I need to test it a little more.
1030    o pkg/cheapaml:
1031      - fix few incorrect type (_RL/_RS) in subroutine calls.
1032    o pkg/seaice:
1033      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1034        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1035    o model/src:
1036      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1037        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1038        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1039    o pkg/cheapaml:
1040      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1041        update output of experiment cheapAML_box.
1042      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1043        and set them only in one place (cheapaml_readparms.F).
1044      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1045      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1046        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1047    o model/src/the_main_loop.F:
1048      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1049    o pkg/seaice:
1050      - remove legacy branch code.
1051      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1052    o verification/*/code*/SEAICE_OPTIONS.h:
1053      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1054        SEAICE_CAP_HEFF).
1055    o pkg/cheapaml:
1056      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1057        to load new forcing fields.
1058      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1059      - remove switch to "-r8" compiler option (no longer needed) in verification
1060        cheapAML_box, keep same output (small trucation error differences).
1061    o verification/offline_exf_seaice:
1062      - add thermodynamics only test.
1063    o verification/cheapAML_box:
1064      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1065        keep same output (same 14 digits for cg2d).
1066      - switch on "-r8" compiler option (some numerical values are missing
1067        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1068    
1069    checkpoint64b (2012/12/24)
1070    o pkg/cheapaml:
1071      - remove un-used variables (Qnet,EmPmR) from pickup files.
1072      - store tendency of advected variables into cheapaml pickup file
1073        and fix the AB-2 restart.
1074    o verification/offline_exf_seaice and lab_sea adjoint:
1075      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1076      - switch to 4 time steps in offline, consistent with lab_sea.
1077      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1078      - update results after change of experiment seaice.
1079    o pkg/seaice:
1080      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1081        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1082        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1083        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1084    o model/src:
1085      - add run-time parameter to select CG2D solver minimum-residual solution
1086        (in case of a poor convergence).
1087    o pkg/seaice/seaice_lsr.F
1088      - move calculation of matrix coefficients into new
1089        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1090        file; the main purpose of this change is to be able to reuse the code
1091        in S/R SEAICE_PRECONDITIONER
1092      - modify the computation of the residual so that the mass of sea-ice
1093        is not used twice; this simplifies the calculations, but since
1094        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1095        not tested in testreport---this does not affect the testreport results.
1096    o verification/seaice_obcs:
1097      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1098        verification/lab_sea/input.salt_plume; changes results/output.txt*
1099    o model/src:
1100      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1101    o pkg/seaice:
1102      - improve description of parameters in seaice_fgmres.F and start
1103        cleaning up the code
1104      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1105        second argument
1106      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1107        results of offline_exf_seaice.dyn_jfnk
1108      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1109    o pkg/aim_v23:
1110      - fix an other bug in dissipation heating (grid-cell area was missing).
1111    o model/src + pkg/seaice:
1112      - add global (multi-tile) linear solver for pair of tri-diagonal system
1113        along X and Y lines, respectively for U and V component.
1114        Note: 1) MPI and cube-exchange not yet coded.
1115            2) probably not accurate for poorly conditioned / large size problem.
1116      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1117        default: not compiled and not used.
1118    o pkg/seaice:
1119      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1120        introduce bi/bj loops and use global_sum_tile_rl instead of
1121        mpi_allreduce in seaice_fgmres.F
1122      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1123      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1124      - add a verification experiment for JFNK in offline_exf_seaice
1125    o verification:
1126      - change (for now, only fwd test) offline_exf_seaice experiment:
1127        use a re-entrant channel with idealized coastline (trapezoidal shape)
1128        at southern boundary to explore seaice dynamics and thermodynamics
1129        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1130        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1131      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1132    o pkg/exf:
1133      - disable "sstExtrapol" when Nr=1
1134    o verification:
1135      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1136        to test pkg/cheapaml.
1137    o pkg/aim_v23 & pkg/shap_filt:
1138      - fix dissipation heating (erroneous gravity multiplication factor).
1139    o pkg/seaice:
1140      - remove unused field pressPre from jfnk solver
1141      - rename two subroutines in seaice_preconditioner.F
1142    o eesupp/src:
1143       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1144    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1145       - remove wrong parts of the rhs and the lhs (were in there
1146         because I did not understand the concept of this preconditioner)
1147       - add an exchange between u- and v-sweep. This increases communication
1148         by a factor of two but improves the convergence of jfnk. Ideally,
1149         one would like the u- and v-sweep to be independent. So far within
1150         undocumented ifdefs
1151       - reorganize the extra computations for printing the residuals
1152    o tools/genmake2:
1153      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1154        since it's not necessary (and was preventing to use MNC in some cases).
1155    
1156    checkpoint64a (2012/11/16)
1157    o pkg/autodiff:
1158      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1159        autodiff_readparms.F no longer depends on calling order (within
1160        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1161        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1162        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1163    o pkg/obcs:
1164      - adding tidal velocity forcing capability to obcs
1165        for usage example, see verification/seaice_obcs/input.tides
1166    o pkg/seaice:
1167      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1168        SEAICE_LSRrelaxU/V
1169      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1170    o pkg/aim_v23:
1171      - implement heating from friction (bottom friction and stratospheric drag).
1172    o pkg/shap_filt:
1173      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1174        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1175    o model/src:
1176      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1177        time-constant addMass field from file (addMassFile);
1178      - support for heating due to friction (and Kinetic Energy dissipation):
1179        add option, run-time switch and 3-D field array + support code ; each pkg
1180        or S/R can add heating contribution (if there is a sink of KE); the sum is
1181        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1182    o pkg/seaice:
1183      - complete merge of ITD code into seaice_growth.F
1184        from MITgcm_contrib/torge/itd/code/
1185        no verification so far, but Torge Martin tested
1186        "1-D test case and Beaufort set up;
1187        deliver okay results after 1 model year."
1188      - complete merge of SEAICE_SIZE.h into all relevant routines
1189      - move computation of eta at Z-points into calc_viscosities
1190        + introduce global field etaZ
1191        + add different methods for computing etaZ, for now the old
1192          method (simple averages of eta to Z-points) is hardwired
1193        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1194          seaice_preconditioner
1195      - simplify computations for SEAICE_ZETA_SMOOTHREG
1196      - seaice_preconditioner:
1197        + replace one remaining press by pressLoc (mistake)
1198        + adjust printing of residuals
1199      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1200        + add (SEAICE.h) and rename some counters (initiliased in
1201          seaice_init_fixed.F)
1202        + add _BEGIN/END_MASTER (myThid)  around print statements
1203        + print total number of iterations and failures over SEAICE_monFreq
1204          interval to STDOUT
1205      - move control over output-messages by fgmres to seaice_jfnk to save
1206        some operations
1207      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1208        in order to make restarts with sol .ne. zero (fgmres with restarts)
1209        (seaice_jfnk.F, seaice_fgmres.F)
1210      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1211        a serious convergence problem when open boundaries are involved
1212    o pkg/ggl90: fix computation of control volumes for the case of
1213      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1214      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1215    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1216    o pkg/autodiff
1217      - Add inAdMode switch for SEAICEuseDYNAMICS:
1218        SEAICEuseDYNAMICSinAdMode
1219        (extend logic in ADAUTODIFF_INADMODE_SET)
1220    o pkg/seaice
1221      - Step 1 of merging ice-thickness distribution (ITD) code from
1222        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1223        The code implements concept laid out in Thorndike et al. (1975);
1224        code is enabled via CPP flag SEAICE_ITD
1225        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1226        code is not complete yet!!
1227      - SEAICE_SIZE.h now included in almost all seaice routines
1228    o verification (using seaice):
1229      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1230        global_ocean.cs32x15.seaice ; update results.
1231      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1232      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1233        offline_exf_seaice (previously compiling B-grid).
1234    o pkg/exf:
1235      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1236        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1237        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1238    o pkg/layers (adjust changes from Sept 19):
1239      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1240        this allows to remove "layers_maxNum" dimension from all layers arrays.
1241    o pkg/layers (adjust changes from Sept 19):
1242      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1243      - snap-shot extended to all type of layers (not just the 1rst type);
1244      - remove layers variables when corresponding CPP option is undef.
1245    o pkg/layers:
1246      - rename pkg/layers variable and add new output (layer exist & un-weighted
1247        velocity in layer)
1248    o pkg/seaice:
1249      - simplify (?) ocean-drag coefficent computations by using
1250        the same routine in all three solvers (saves some code lines)
1251      - remove global fields DRAGA and DRAGS from C-grid code and
1252        declare them locally in lsr.F (the only place where they are
1253        still used)
1254      - update AD output of lab_sea.evp (very sensitive anyway).
1255    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1256      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1257      and SEAICEuseJFNK=.true. A few things to note:
1258      - involves a FGMRES, that is parallel but very inefficient,
1259        because of many scalar products (global sums) in the Gram-Schmidt
1260        orthogonalization method. Needs to be replaced. Original code
1261        from J.-F. Lemieux
1262      - preconditioner for FGMRES is a stripped down version of LSOR
1263      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1264        preconditioner. For the preconditioner, the default is set to 10.
1265      - Jacobian times vector is computed with finite differences
1266      - marginally related to JFNK-solver: add a smooth regularization for
1267        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1268        2009) for any implicit solver (not implemented for EVP because EVP
1269        does not need this regularization in the first place). Define
1270        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1271    o eesupp/src:
1272      - check in genmake2 that intrinsic S/R flush is available.
1273      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1274      - flush standard & error msg unit before MPI termination
1275      - if debugMode, flush IO unit after printing msg
1276    o pkg/ctrl:
1277      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1278        to ctrl_set_unpack_xyz.
1279    
1280    checkpoint64 (2012/10/09)
1281    o pkg/shelfice
1282      - in mom_fluxform.F, mom_vecinv.F:
1283        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1284        Bug fix KappaRU -> KappaRV
1285        does not change verification/isomip but may change other setups
1286        (presumably constant KappaRU=KappaRV)
1287      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1288    o pkg/obcs:
1289      - fixed some indexing bugs in obcs_seaice_sponge.F
1290      - added obcs relaxation subroutines for HSALT and HSNOW
1291      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1292    o pkg/seaice:
1293      - add "multicategory" parameterization for snow in analogy to ice,
1294        default is off for now.
1295    o pkg/obcs:
1296      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
1297        see verification/seaice_obcs/input.seaiceSponge for example application.
1298      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
1299        index setting by master-thread. This fix multi-threads Pb in previous modifs.
1300    o pkg/layers :
1301      - add diagnostics to pkg/layers
1302      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
1303        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1304    o pkg/generic_advdiff/gad_implicit_r.F :
1305      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1306    o pkg/seaice/seaice_growth.F:
1307      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1308    o pkg/obcs:
1309      - change default setting of OBCS_UVICE_OLD from defined to undef;
1310      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1311        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1312      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1313      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1314        with Southern & Western OB at a tile edge (at least in a simple set-up).
1315    o pkg/obcs:
1316      - change settings of OB index in case OB coincides with tile edge (shared by
1317        2 tiles), so that common OB location is registered by both tiles (instead of
1318        only 1). However, for Southern and Western OB, index value = 0 is not
1319        recognized as valid OB index (=default null value) and needs to be fixed.
1320      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1321      - new parameter "OB_indexNone" for null index value (for now, still zero)
1322        to replace hard-coded null index value of zero.
1323    o pkg/exch2:
1324      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1325        always check buffer-size (but outside the loop); move checking for valid
1326        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1327        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1328    o pkg/ctrl (pack & unpack):
1329      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1330        (locally defined) for different variables (+ remove the variable-specific
1331        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1332        (to be extended to other local file names in ctrl.h).
1333    o pkg/flt:
1334      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1335    o pkg/mdsio:
1336      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1337    o tools/genmake2:
1338      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1339        (added by Alistair in version 1.51 for building without make depend);
1340      - remove Header files list (H_SRC_FILES) from the dependence of targets
1341         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1342        place in version 1.23): this save going through staf when unrelated header
1343        file has been modified.
1344       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1345        "make depend" step, still need to do "make links" before "make adtaf".
1346    o eesupp/src (+ few pkg src files) & genmake2:
1347      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1348      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1349      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1350         upper/lower case ; account for space between "#" and undef/define)
1351    o pkg/flt (with exch2):
1352      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1353      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1354    
1355    checkpoint63s (2012/09/05)
1356    o pkg/ecco:
1357      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1358      - add more relevant #ifdef ALLOW_SMOOTH ones.
1359      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1360    o pkg/ctrl:
1361      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1362        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1363      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1364        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1365        ctrlSmoothCorrel3D (new).
1366        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1367      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1368      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1369        controls when useAtmWind, and vice versa.
1370      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1371      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1372          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1373      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1374          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1375      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1376        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1377    o pkg/smooth:
1378      - remove un-necessary includes.
1379      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1380        Those CPP options were never defined, and not necessary.
1381    o model/src:
1382      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1383      - standard treatment of useSMOOTH.
1384    o pkg/autodiff:
1385      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1386        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1387    o pkg/exch2:
1388      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1389        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1390      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1391        and tiles to process mapping.
1392      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1393        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1394        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1395        from w2_eeboot.F to w2_readparms.F.
1396    o eesupp/src:
1397      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1398        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1399        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1400      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1401        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1402        has been called.
1403      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1404      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1405        (so that on 1 proc, get same myPid independently of usingMPI)
1406      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1407        useCubedSphereExchange with EXCH-1 (safer).
1408      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1409    o pkg/ggl90:
1410      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1411        used in ALLOW_GGL90_SMOOTH code.
1412    o pkg/flt:
1413      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1414        floats at the Southern end of the domain).
1415    o eesupp/inc:
1416      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1417        but not used (and not to be used) anywhere, just for documentation.
1418    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1419      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1420        a) can damage previously written records in any other multi-record files.
1421        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1422  o tools/genmake2:  o tools/genmake2:
1423    - define variable MAKE within Makefile and use it in place of 'make';    - define variable MAKE within Makefile and use it in place of 'make';
1424    - 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 1426  o tools/genmake2:
1426      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;
1427    - always print usual warning comment 'this file is automatically generated'    - always print usual warning comment 'this file is automatically generated'
1428      from script convert_cpp_cmd2defines (+ remove this warning from genmake2).      from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1429    o pkg/cheapaml:
1430      - updated to correspond to the code used in accepted paper (Nico Wienders).
1431  o pkg/exf:  o pkg/exf:
1432      added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.      added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1433      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)
