4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/sbo:
8      - update from Katherine Quinn: evaluate mass directly from density and SSH
9        (budget using Finite Volume method) instead of from bottom pressure.
10      - allow testreport to collect few selected SBO output ; tested in exp.
11        global_ocean.90x40x15 (after updating the results, to include SBO output).
12      - fix some multi-threading issues (in output part).
13    o model/src & most packages:
14      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
15      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
16        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
17        "data.{pkg}" exist ; and leave the S/R (return) just after.
18      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
19        + call LAND_READPARMS from packages_readparms.F
20    o pkg/seaice:
21      - remove code that resets useThSice in S/R seaice_readparms and
22        replace by a warning in S/R seaice_check
23      - remove parameter MULTDIM, replace with nITD and runtime
24        parameter SEAICE_multDim (still hard-wired to nITD if
25        SEAICE_ITD is defined)
26    
27    checkpoint64x (2014/05/24)
28    o verification/lab_sea:
29      - update adjoint and TLM output following changes to pkg/salt_plume
30      - un-do the update after putting back local recip_Cp in few places.
31    o pkg/salt_plume: modifications by An Nguyen:
32      - add capability to do brine rejection (salt-plume) as function of
33        volume+tracers (instead of only salinity tracer).
34      - conserve volume by exchanging volume from each kLev to above to
35        accommodate in-coming brine volume
36      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
37      - switch KPP surf buoyancy due to brine forcing to 3-d
38        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
39      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
40      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
41        in East/West Arctic.
42    o pkg/sbo:
43      - incorporate modifications from Katherine Quinn to enable the use of sbo
44        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
45        output for future testreport verification (unfinished).
46    o pkg/atm_phys:
47      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
48        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
49        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
50    o pkg/seaice
51      seaice_calc_ice_strength.F: modify expression to avoid divisions
52        (affects truncation)
53      seaice_do_ridging.F: clean up the insectarium
54      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
55      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
56      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
57      - add some debugging information and error messages (warnings)
58    o model/src: modifications relatd to atmosphere p*:
59      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
60      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
61        of vertical profile tRef in geopotential background and anomaly.
62      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
63        and pkg/atm_phys.
64      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
65        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
66    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
67    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
68        not used right now, but can be used in BGC packages to fix conservation.
69    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
70        other packages too.
71    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
72        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
73    o model/src:
74      - since we have several heat capacity (even in model/src), define "recip_Cp"
75        as local variable (no longer in common block) to avoid any confusion.
76      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
77    o pkg/exf:
78      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
79        air density as function of air Temp, Humidity and atm pressure.
80    
81    checkpoint64w (2014/05/02)
82    o verification:
83      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
84        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
85        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
86        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
87        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
88    o model/src: for atmosphere in p* coords:
89      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
90      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
91        but not yet activated.
92    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
93      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
94      - this changes the results (but not for any verification experiment, because
95        none tests this), but avoids having an extra field in the restart files
96    o pkg/seaice: remove global variable TICE (not needed)
97      - replace by TICES or local variable where necessary (cost_seaice_test,
98        seaice_diagnostics_state)
99      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
100      - use specific read/write routines for reading and writing individual leves
101        of a multilevel field
102    o pkg/ctrl & model/inc:
103      - move additional anomaly fields of control vars (related to options:
104         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
105        from DYNVARS.h into new header file: CTRL_FIELDS.h
106    o pkg/seaice: some small modifications to the ridging code
107      - make fw2ObyRidge a global variable and add the freshwater flux to
108        seaice_growth
109      - pass actual thickness from seaice_prepare_ridging, so that it is
110        computed only in one place and compute it in the same way as in
111        seaice_growth
112      - initialise more fields in seaice_do_ridging that where cause floating
113        point exceptions over land
114    o pkg/seaice: preparations for ridging code and first real ridging code
115      - move most of "PART 1" of S/R seaice_growth into a new and separate
116        S/R seaice_reg_ridge that will both regularize the state variable after
117        advection call the actual ridging routine;
118      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
119        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
120      - remove ridging code from seaice_advdiff
121      - clean up remaining part 1 of seaice_growth in an attempt to make it
122        more readable (this is probably subjective)
123      - call seaice_itd_redist once in the initialisation phase to have the initial
124        conditions in the correct category
125      - finally: add new ridging routine for ITD code
126    
127    checkpoint64v (2014/04/11)
128    o pkg/ecco:
129      - add runtime parameters mdt[start,end]date[1,2]
130      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
131    o pkg/seaice:
132      - make deltaC a global variable, so that it can be used in ridging code
133      - first step towards ridging: introduce new routines that compute
134        ice strength based on ridging parameters
135      - add diagnostic for HSNOWITD
136      - add opnWtrFrac as a global variable (required for ridging scheme)
137    o pkg/salt_plume + pkg/seaice/seaice_growth.F
138      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
139        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
140    o verification/hs94.1x64x5:
141      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
142      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
143    o autodiff:
144      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
145        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
146        For now, only in pkgs used in verification/hs94.1x64x5.
147      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
148        which are specific to TAF/TAMC).
149      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
150        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
151        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
152      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
153        building mitgcmuv_ad (make adAll).
154    o pkg/ecco:
155      - cost_gencost_seaicev4.F:
156         reformulate proxy cost as function of sst and local param SEAICE_freeze
157         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
158      - add stop statement if old names siv4-[sst,vol] are used
159      - add snapshots + cost reports for atmospheric longwave
160      - remove factor 0.1 in front of wtau[u,v]
161      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
162         ALLOW_TMI_SST_COST_CONTRIBUTION
163    o pkg/atm_phys:
164      - add some diagnostics for Short-wave and for convection S/R.
165    o pkg/seaice/seaice_growth:
166      - fix a bug in the lateral melt parameterization for SEAICE_ITD
167        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
168      - rearrange loop order for better vector code in the same code block
169      - rewrite the floeDiameter formula to have fewer divisions
170      -  (miraculously) none of this changes the results of seaice_itd
171    o pkg/smooth:
172      - move param smooth2Ddiffnbt to pkg/ecco
173    o pkg/salt_plume:
174      - salt_plume_frac.F:
175         clean up local param names
176         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
177    o pkg/rw:
178      - add RS version of S/R READ_MFLDS_LEV.
179    o pkg/streamice:
180      - fix the restart test by writing/reading pickup_streamice files.
181    o pkg/seaice:
182      - refine checks for jfnk-related parameters
183      - comment out if statement with SEAICEuseIMEX parameter as long as there
184        is no IMEX code to avoid confusion and surprises
185    
186    checkpoint64u (2014/03/07)
187    o verification/MLAdjust:
188      - rename secondary test suffix:
189         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
190         0.leithD -> AhFlxF  + switch to flux-form
191         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
192         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
193    o pkg/mom_vecinv:
194      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
195        to be before mom_calc_visc.F)
196      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
197      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
198        this is simpler for the adjoint and for diagnostics.
199    o model/src + pkg/momentum:
200      - add input files for  2-D additional Western and Southern cell-edge wall
201         (e.g., to add "thin-wall" where it is =1).
202      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
203        using 2nd hFacZ that is computed from initial (fix domain) hFac
204      - known limitations of thin wall implementation: not yet coded for sigma
205        coords; not working with CD-scheme neither.
206    o pkg/seaice:
207      - rename recently introduced parameters from (wrong name) AB to
208        BDF (backward difference time discretisation)
209      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
210    o tools/adjoint_options:
211      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
212    
213    checkpoint64t (2014/02/01)
214    o pkg/ecco
215      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
216        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
217      - replace hard-coded record number and period which only work for monthly
218        with read-in runtime param that works for other periods (month,day,year)
219    o pkg/thsice
220      - corrected store directive fixes thsice adjoint gradient checks
221    o genmake2 & testreport:
222      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
223        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
224        Update testreport accordingly. No need to set "export OPENAD=true"
225        in adjoint_options/adjoint_oad anymore (will be removed later).
226    o pkg/shelfice:
227      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
228        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
229        so that surface forcing applies to k=kSurf if using pkg/shelfice.
230    o pkg/ctrl, pkg/grdchk, pkg/ecco:
231      - Changes to make GENARR more modular (i.e. invisible if not used)
232    o model/src/temp_integrate.F and salt_integrate.F
233      - re-include store directives that were removed on Dec 27th.
234    o model/src/external_forcing_surf.F
235      - add storage directives for EmPmR and PmEpR to avoid recomputation of
236        seaice_model in the adjoint that is problematic when seaice_model is
237        turned off in the adjoint. The resolved issue dated back to July when
238        EXTERNAL_FORCING_SURF call was moved.
239        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
240    o pkg/exf/exf_check.F
241      - fix a small bug again (originally found by Wentao Liu, now found again)
242      - streamline error output
243    o pkg/streamice and aim_v23:
244      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
245        Apple's /usr/bin/cpp knows what to do:
246        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
247        Target: x86_64-apple-darwin13.0.0
248    
249    checkpoint64s (2014/01/05)
250    o tools/adjoint_options:
251      - switch to fastopt.net TAF server (instead of default fastopt.de) for
252        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
253    o model/src:
254      - remove some unnecessary TAF storage directives in forward_step.F and
255        in dynamics.F (note: not always removed by TAF, e.g., double storage
256        of kappaRU,kappaRV in former version of dynamics.F).
257    o model/src & pkg/ptracers:
258      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
259        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
260        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
261      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
262      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
263      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
264    o useSingleCpuInput separates single-CPU input from single-CPU output;
265        for now only implemented for in exf_interp_read.F
266    o verification/advect_xy:
267      - fix missing EXCH call in local version of ini_salt.F and update output.
268    o momentum diagnostics:
269      - fix which deltaT is used in Total-Tendency diagnostics.
270      - fix typo in diagnostics for momentum tendency from AB.
271    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
272        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
273    
274    checkpoint64r (2013/12/08)
275    o verification/*/results:
276      - Update reference output of experiments that were passing with just 13 digits
277         (make it easier to detect future changes in results)
278    o model/src & pkg/ptracers:
279      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
280        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
281        to inside ptracers_integrate.F ; remove ptracers_advection.F
282    o coupling interface pkgs:
283        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
284      - change the config check to test the agreement of Ocean Depth
285        with ATM land/sea mask (instead of ATM orography);
286      - send to coupler the number of coupler time-steps to do for this run:
287        this allows to check for consistency and don't need anymore to be
288        specified in parameter file "data";
289      in coupler:
290      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
291      - improve report to log-file of config setting (pass log-file unit to few S/R)
292    o pkg/compon_communic:
293      - add coupling send/receive for non-tiled integer vector;
294      - add S/R to check and stop if any proc has an error (similar to
295        eesupp/src/stop_if_error.F but single thread and across Comm_World).
296    o pkg/exch2:
297      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
298        through list of all tiles my proc owns.
299    o model/src:
300      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
301        from rTrans) to simplify dependencies (no need to store rTrans anymore in
302        calling S/R); this affects AD results at machine truncation level:
303        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
304        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
305    o tools/build_options:
306      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
307    o coupling interface pkgs:
308        [compon_communic, atm_compon_interf & ocn_compon_interf]
309      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
310        to each S/R that needs it; remove un-used variables.
311      - change component tile registration (cpl_register.F in both compon_interf
312        and mitcomponent_tile_register.F) to pass the full list of tiles
313        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
314      - with pkg/exch2: adopt the same convention used for I/O to define mapping
315        towards coupler global array (unless W2_useE2ioLayOut=F):
316         a) can now use different tiling between atm & ocn comp.
317         b) no needs to modify the run-Off map when changing tiling (was needed
318            even if using the same tiling between atm & ocn).
319         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
320            full land tiles); not yet tested.
321      - check for valid mapping from comp. tile to coupler global array
322      - improve report of tile registration results to log file.
323    o pkg/exch2:
324      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
325        tile-registration (CPL_REGISTER);
326      - activate (un-comment) definition and setting of "W2_tileIndex" list to
327        store the local bi,bj indices of each tile;
328      - also print bi,bj in local report to log file;
329      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
330        Jun 2009 modif of pkg/exch2).
331    o testing on baudelaire:
332      - run 2 tests at a time: no significant slow down (since enough cpu) and
333        get the full set of test done earlier
334      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
335    o model/src/thermodynamics.F and routines called from it:
336      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
337        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
338        velocity (outp) by adding bolus velocity.
339      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
340        mass transport from velocity + lateral grid cell area
341      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
342      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
343     in thermodynamics.F
344      - remove k from thermodynamics.F and move it to temp_integrate.F
345        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
346        loop).
347      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
348        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
349        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
350        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
351      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
352        global_ocean.90x40x15, tutorial_global_oce_biogeo and
353        tutorial_tracer_adjsens (+ TLM output).
354    o tools/OAD_support and (verification/*/) code_oad:
355      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
356        module conversion ; remove unneeded CPP_EEOPTIONS.h.
357      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
358        version (closer to model/inc/CPP_OPTIONS.h).
359    o model/src:
360      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
361        retired list of parameters (routine FREEZE has been replace by surface
362        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
363    o pkg/gmredi:
364      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
365        velocity (same scheme but affects machine truncation) for GM_AdvForm.
366      - update output of FWD experiments: front_relax.bvp,
367        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
368    
369    checkpoint64q (2013/11/17)
370    o verification:
371      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
372        tutorial_global_oce_biogeo and global_ocean.90x40x15.
373      - generate new output (growth & melt) for seaice_itd experiment after
374        updating the input pickup_seaice files (previously wrong).
375    o pkg/cost:
376      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
377        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
378        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
379          cannot be applied to var in common block).
380        o allows to get results independent of tile-per-proc setting (if using
381          slower GLOBAL_SUM_SEND_RECV option).
382      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
383        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
384        forward gradients: update output).
385      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
386        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
387    o pkg/mom_common:
388      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
389        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
390        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
391        ensure that all field value that are used are set.
392    o tutorial_deep_convection (smag3d):
393      - add missing scaling in mom_calc_smag_3d.F;
394      - set smag3D_coeff in input.smag3d such that results do not change.
395    o pkg/dic:
396      - change dic_cost.F to compute cost on each tile first and then apply
397        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
398        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
399      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
400    o eesupp/src & pkg/mdsio:
401      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
402        (from pkg/mdsio) since they are no longer used for tape IO.
403      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
404        (+ keep a copy in pkg/atm_ocn_coupler).
405    o verification/isomip:
406      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
407    o tools/build_options:
408      - optfile linux_amd64_ifort11, fast (no ieee) case:
409        to get a working restart for all experiments, add "-fp-model source"
410        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
411    
412    checkpoint64p (2013/10/20)
413    o pkg/autodiff:
414      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
415        criteria, return to simple (default) tape IO format.
416    o pkg/mdsio (+ eesupp/src):
417      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
418        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
419      - fix globalFile and singleCpuIO options using simpler global mapping.
420      - new pairs of scatter/gather vector S/R (one for each type, generated from
421        template) corresponding to simpler global mapping.
422      - adread_write.F: switch to new S/R (but leave old calls commented) and write
423        to globalFile when parameter globalFiles is set to True.
424      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
425    o pkg/autodiff:
426      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
427        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
428        missing, just add a STOP if array type do not match.
429    o pkg/exf:
430      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
431         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
432         and rename array obsSIce to exf_iceFraction.
433    o tutorial_deep_convection:
434      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
435        for now all in this exp. code dir.
436      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
437        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
438    o eesupp/src:
439      - added SINGLE_DISK_IO option because reading of parameter files on
440        very large number of processors did not work with existing set-up
441    
442    checkpoint64o (2013/09/25)
443    o pkg/atm_phys & atm_compon_interf:
444      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
445    o tools/build_options:
446      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
447        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
448        remove CPP setting (was identical to genmake2 default).
449    o pkg/gmredi & model/src: Some updating and work done on the residual model.
450      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
451      - fixed up the calculation of the eddy stress and how it is added to the
452        external forcing via taueddy_external_forcing.F
453      - at the moment, it is very experimental and only works with the variable eddy
454        diffusivity calculated in gmredi_k3d.F
455    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
456        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
457    o testreport (& tools/do_tst_2+2):
458      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
459    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
460      - remove CPP='cpp -traditional -P' (this is genmake2 default)
461      - add switch (for big setups) to use 'medium' memory-model (but leave it
462        commented out for now). Note: needed with FC 19 to compile big setups.
463    o pkg/atm_compon_interf:
464      - regroup per field origin (model & pkgs) the coupling storage routines
465         (which accumalate in time each coupling field)
466      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
467        update accordingly + simplify aim_do_physics.F
468    
469    checkpoint64n (2013/08/26)
470    o pkg/bbl:
471      - update formulation to reduce dispersion of tracer properties in bbl
472      - replaced horizontal and vertical transport parameters with velocities
473      - changes results for verification/global_with_exf.yearly
474    o verification/halfpipe_streamice:
475      - change to matrix construction; update both Fwd & AD output.
476    o verification/tutorial_tracer_adjsens:
477      - OpenAD test: switch to vector-invariant momentum since fluxform with
478        rStar causes problems with OpenAD; update output.
479    o tools:
480      - genmake2: define a common prefix for all temp-file names ; move them
481        to local /tmp disk (but would be easy to move them back);
482      - xmakedepend: apply the same switch for temp-files.
483    o pkg/offline:
484      - changes for use with rStar (NLFS): assume that we continue to provide
485        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
486        output files) and apply r* scaling at each time-step (function of the time
487        varying Eta field); use normal pickup files (needed for restart with NLFS).
488    o adjoint with OpenAD:
489      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
490        package openad.  This package has to be compiled for all runs with OpenAD
491        instead of specifying code_oad_all as a modification directory.
492      - link the fortran templates from tools/OAD_support to the build directory
493        for preprocessing to avoid conflicts between different setups compiled
494        simultaneously and simplify cleanup.
495    o pkg/exf:
496      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
497        main model or other pkgs are exchanged in EXF_MAPFIELDS).
498    o model/src:
499      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
500        (similar to do_fields_blocking_exchanges.F).
501    o tools/genmake2:
502      - remove TAF output src code just before calling staf (when not doing a fresh
503        built, will stop if things go wrong with staf).
504      - fix target "adobj" (left from TAF version-2 transition)
505    o pkg/diagnostics:
506      - add a parameter to track the status of pkg/diagnostics activation;
507        this replace/extend the use of logical param "settingDiags" (to check
508        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
509        New S/R to print error message and stop when pkgStatus is not right.
510      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
511    
512    checkpoint64m (2013/08/13)
513    o model/inc:
514      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
515        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
516    o pkg/kpp & aim_v23:
517      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
518    o pkg/seaice:
519      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
520        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
521      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
522    o eesupp/src:
523      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
524        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
525    o switch to TAF version-2:
526      - add flow directives to "freeze" naming convention for ad-routines that
527        are used in I/O routines of adjoint state and associated common blocks
528        that are used in adcommon.h (backward compatible with version-1)
529      - update all ad-optfiles (in tools/adjoint_options + few local to some
530        verification exp) to switch to latest TAF version (currently 2.5.5);
531        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
532        out except for diva).
533      - the major change with TAF version-2 is that both the differentiated
534        routines and the forward routines (new) are returned as part of the TAF
535        output source code. Update genmake2 accordingly.
536      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
537        with version-2 when compared to TLM or FWD gradient); other experiments
538        output show minor changes (machine truncation level); update the few AD &
539        TLM output with 12 matching digits only (some prior to version-2 switch).
540    
541    checkpoint64l (2013/08/05)
542    o model/src:
543      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
544      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
545        when using TAF but only if using OpenAD.
546    o pkg/mom_common+fluxform+vecinv:
547      - always set horiz. viscosity arrays to background value before calling
548        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
549        only when using variable horiz. viscosity (useVariableVisc=T);
550      - simplify mom_vecinv.F (only 1 block for momViscosity).
551    o pkg/mom_common: variable horiz. viscosity in NH code
552      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
553        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
554      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
555        useBiharmonicVisc & useVariableVisc.
556      - fix old bug (already in 1rst implementation of variable horizontal viscosity
557        in calc_gw.F, version 1.27, 2006/06/20):
558        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
559        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
560      - change background horiz viscosity in vertical momentum (gW) to always be
561        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
562        any type of variable viscosity, e.g., viscAh/4Grid)
563      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
564        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
565        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
566        default viscAh,viscA4 is zero).
567    o model/src:
568      - extend length of drC & recip_drC from Nr to Nr+1.
569    o Divided Adjoint (DIVA) with MPI:
570      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
571      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
572        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
573    
574    checkpoint64k (2013/07/23)
575    o tools/OAD_support:
576      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
577        and remove it from genmake2.
578    o tools/build_options:
579      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
580        MPI_HEADER_FILES list (let genmake2 find the missing headers)
581    o verification/halfpipe_streamice:
582      - change to driving stress formulation; update both Fwd & AD output.
583    o tools/genmake2 and Divided Adjoint with MPI:
584      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
585      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
586      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
587        Makefile, which is set by genmake2, and check which mpi-headers are needed.
588        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
589      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
590    o testreport:
591      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
592        perform additional runs (number of additional runs is "add_DIVA_runs" taken
593        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
594    o verification/lab_sea (AD test):
595      - change to test Divided Adjoint Run in this set-up (both standard AD test
596        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
597    o pkg atm_ & ocn_compon_interf:
598      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
599        staggerTimeStep implementation) and disable (retired) corresponding
600        parameter.
601    o pkg/offline:
602      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
603      - add S/R OFFLINE_CHECK to print offline parameter summary
604        and stop if loading a file that is not used;
605      - enable to calculate GMRedi tensor, KPP mixing and convective index
606        when the corresponding file(s) is/are not specified (but pkg is used).
607      - comment out resetting of monitorFreq (to endTime) since it still useful
608        for monitoring CFL numbers and checking offline fields.
609    o OpenAD:
610      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
611        smaller standard output) and generate new (smaller) output (on baudelaire
612        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
613    o model/src:
614      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
615        (where external_forcing_adjust was called) and change list of arguments;
616      - merge external_forcing_adjust.F into external_forcing_surf.F
617      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
618        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
619        previously in file "balance_relax.F", now removed); remove corresponding
620        arrays in FFIELDS.h.
621      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
622        a hack for getting back surfaceForcingS (loaded from file) when using
623        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
624      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
625        (was getting only 11 digits for AD-grad, due to different truncation
626         error in AD code).
627    
628    checkpoint64j (2013/07/04)
629    o pkg/offline:
630      - to enable the use of other features with pkg offline (e.g., obcs),
631        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
632      - comment out "allowFreezing" (now active) in 2 offline testing exp.
633    o pkg/exf ALLOW_RUNOFTEMP
634      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
635      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
636      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
637    o pkg/atm_phys:
638      - allows to add some damping on uVel,vVel (strength only function of k).
639    o verification, ad-tests:
640      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
641        global_ocean_ebm and offline_exf_seaice.thsice.
642    o verification/halfpipe_streamice:
643      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
644        flux input boundary conditions to be ignored; a fix for this bug changed
645        verification results for forward test.
646      - add adjoint test.
647    o pkg/ptracers:
648      - allow to restart without SOM pickup (resetting SOM to zero).
649    o pkg/gmredi:
650      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
651      - It uses mixing length theory and suppression by steering level effects to
652        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
653        to JPO, for more details).
654      - It also uses the diffusivity to calculate an eddy induced streamfunction
655        based on a PV closure (rather than a buoyancy closure as in GM).
656      - New files added to pkg/gmredi:
657        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
658          induced overturning streamfunction (called from gmredi_calc_tensor)
659        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
660          for use in gmredi_k3d
661        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
662          the eddy diffusivity
663    
664    checkpoint64i (2013/06/18)
665    o pkg/cheapaml:
666      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
667        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
668        with pkg/cheapaml.
669    o utils/python: add subpackage for cubed sphere function, first example is
670        simple cs.pcol to plot 2D fields on a map
671    o pkg/streamice:
672      - This is a new package in MITgcm, which solves dynamic equations for ice
673         sheets and ice streams
674      - At the moment it is independent of atmosphere/ocean dynamics, or any
675        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
676        ed that this will change)
677      - There is a new verification exercise that tests it, halfpipe_streamice,
678        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
679        rectangular embayment
680      - halfpipe_streamice is forward-only for now, will have TAF test soon
681      - for questions, email dgoldber@mit.edu
682    o pkg/thsice:
683      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
684        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
685      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
686         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
687      - allow precip from pkg/cheapaml to make snow over seaice.
688    o pkg/cfc:
689      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
690      - remove atmos CFC 2-D arrays from common bloc (now local variables)
691      - change some hard-coded constant to run time parameter for reading and
692        and interpolating atmospheric CFC ; keep same default as previously.
693      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
694      - put arguments in standard order: myTime, myIter, myThid
695      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
696        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
697      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
698      - new routine to print summary of CFC params and check for consistency.
699    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
700      similar to thsice_advdiff.
701      Note that for the B-grid case the routine parameters uc/vc are overwritten.
702    o pkg/cfc:
703      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
704        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
705      - fix interpolation of atmphspheric CFC between Sorthern and Northern
706        hemisphere value.
707    o pkg/seaice:
708      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
709    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
710                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
711      - requires an additional time level that is stored in the pickup
712      - you can start with AB2 from a pickup without this time level with
713        pickupStrictlyMatch = .false.
714    
715    checkpoint64h (2013/05/26)
716    o pkg/cheapaml:
717      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
718        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
719      - consistent treatment of uWind,vWind location: assume everywhere in
720        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
721        (Note: was already the case for Tair,Qair advection);
722        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
723      - compute diabatic forcing only in the interior (excluding overlap regions)
724      - fill in array "Qsw" (for short-wave heating);
725      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
726        before any update (consistent with MITgcm state var diagnostics);
727      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
728        non periodic ; + adjusted for uWind,vWind (C-grid).
729    o pkg/seaice:
730      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
731        add explicitly pkg/exf in experiments that currently use pkg/seaice.
732      - allows to compile pkg/seaice without pkg/exf.
733    o tools/OAD_support:
734      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
735        of array "ourStepOf" in function rvNextAction (revolve.F90).
736    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
737      - change pkg name (to be used with other atmospheric physics pkg)
738        but by-pass CVS when making the new pkg so that we keep the CVS history.
739    o pkg/offline:
740      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
741        (previously called from pkg/dic_surfforcing_init.F)
742    o model/src:
743      - re-order sequence of calls within packages_init_variables.F, using
744        standard order, except for:
745         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
746         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
747    o new pkg: atm_phys
748      - add entry point and source code (previously in contrib
749          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
750        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
751      - re-order sequence of calls within packages_readparms.F,
752         packages_init_fixed.F and packages_write_pickup.F
753        (but skip packages_init_variables.F because of TAF issues).
754      - update contrib/*/atm_gray/ experiment.
755    o pkg/seaice (ITD code):
756      - simplify and fix the writing of pickup-files for ITD case
757    o pkg/seaice (ITD code):
758      - introduce floe size dependent lateral melt for ITD case;
759      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
760      - update seaice_itd experiment main output.
761    o pkg/thsice:
762      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
763        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
764        changed accordingly pkg/atm2d.
765    
766    checkpoint64g (2013/05/01)
767    o pkg/exf ALLOW_RUNOFTEMP
768      - if defined,  river and glacier runoff temperature can be read-in from
769        runoftempfile; runoftempfile needs to have same format as runofffile
770    o pkg/thsice (& pkg/bulk_force):
771      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
772        for energy content of Precip + RunOff & Evap (like with pkg/exf).
773      - change computation domain to always be the interior (without overlap).
774      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
775    o verification/tutorial_global_oce_biogeo:
776      - add preliminary OpenAD setup (still has problems)
777    o pkg/seaice:
778      - turn some parameters for choosing the convergence criterion of
779        the inexact Newton method (JFNK) into runtime parameters for convenience
780      - clean up seaice_calc_viscosities.F: remove/retire two options for
781        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
782        the results of lab_sea/input because a division has been replaced by
783        a multiplication with the reciprocal (sumNorm)
784      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
785        convergence of solver (changes results, of course), and to test some
786        new features
787    o model/src:
788      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
789      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
790      - move forcing adjustment (balancing surface forcing) in specific S/R
791        where might also be applied exchanges (if needed) to forcing arrays.
792    o pkg/shelfice:
793      - allow to specify the Ice-Shelf mass per unit area (instead of
794        shelficeLoadAnomaly) and do the conversion from one to the other
795      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
796        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
797        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
798        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
799      - update isomip experiment forward output (get machine truncation error
800        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
801    o verification/offline_exf_seaice:
802      revise data.seaice in input.thermo and input_ad and update results accordingly
803        HO = 0.2, SEAICE_areaLossFormula = 2,
804        SEAICE_growMeltByConv = .TRUE.,
805        SEAICE_doOpenWaterMelt = .TRUE.,
806      Improve consistency with input.thsice and fix the spurious 500m ice corners
807    o verification/global_ocean.cs32x15:
808      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
809        in icedyn (thsice+seaice-dyn) test and update output.
810    o verification/offline_exf_seaice:
811      - adjust list of tested variables (with testreport) and update
812        standard test output with better slection of monitored fields.
813    o pkg/cd_code:
814      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
815        experiment lab_sea.hb87
816    o tools/genmake2:
817      - change default makedepend from the system default to tools/xmakedepend:
818        When no makedepend is specified, select tools/xmakedepend it the test pass,
819        otherwise select the system default (if exist and pass the test) or
820        try to build cyrus-makedepend ; stop if none of the 3 works.
821    o pkg/exf & pkg/thsice:
822      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
823        for energy content of Precip + RunOff & Evap. Assumes:
824       1) Rain has same temp as Air.
825       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
826       3) Run-Off comes at the temp of surface water (with same Cp)
827       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
828        put directly into Latent Heat flux & should use water-vapor heat capacity.
829       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
830        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
831    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
832        (compile when SEAICE_ALLOW_JFNK is defined)
833    o pkg/thsice:
834      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
835        implementation): move THSICE_AVE call after the advection (called directly
836        from thsice_do_advect.F).
837    o verification/global_ocean.90x40x15 and OpenAD:
838      New experiment for OpenAD is identical to the one in input_ad except that
839        multiDimAdvection=.FALSE.,
840      There is still an issue with this.
841    o pkg/thsice:
842      - account for ice velocity (ocean relative velocity) in turbulent heat flux
843        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
844        and offline_exf_seaice (main test).
845    
846    checkpoint64f (2013/03/31)
847    o verification/OpenAD:
848      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
849    o verification/isomip, pkg/shelfice and OpenAD:
850      - add OpenAD setup to this exp and make shelfice package work with OpenAD
851    o verification/tutorial_global_oce_biogeo:
852      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
853    o verification/offline_exf_seaice:
854      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
855    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
856      - add OpenAD setup to this exp and make ptracers package work with OpenAD
857    o pkg/seaice/seaice_evp.F:
858       mask the asymmetric contribution of the ice-ocean stress (when
859       the turningAngle is non-zero) over open water to avoid stripes
860       in the EVP-solutions after many EVP-substeps. This does not change
861       the verification experiment (because turningAngle=0 in that experiment),
862       but will affect other EVP solutions with turningAngle.ne.0
863    o verification, AD & TLM output:
864      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
865        additions and multiplications which affect results at machine truncation
866        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
867        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
868        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
869        digits of matching.
870    o pkg/seaice:
871       modify lsr-algorithm so that it vectorizes AND converges by using a
872       "zebra" method: split vector loop into two with step size 2; this
873       solves a general convergence problem for the JFNK solver on a vector
874       computer. It has the potential to even improve convergence for
875       non-vector machines, but it does change the results so it is turned
876       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
877       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
878    
879    checkpoint64e (2013/03/05)
880    o pkg/ecco and several verification experiments:
881       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
882       from ecco package, and revert to unified routine in model/src/
883       Adjust verification experiments accordingly, especially gloal_oce_llc90
884       Should conclude long-standing work by Gael to reconsile the_main_loop with
885       ECCO and will enable OpenAD's revolve loop in ECCO setup.
886    o pkg/generic_advdiff:
887      - implement compressible flow method for multi-dim advection (similar to
888        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
889        TAF generates many recomputations) to use it; no yet coded with implicit
890        vertical advection.
891      - change experiment advect_cs (new output) and advect_xy (same output)
892        to test compressible flow multi-dim advection.
893    o pkg/generic_advdiff:
894      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
895        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
896    o pkg/seaice:
897      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
898        bug affects two verification experiments (lab_sea and lab_sea.hb87),
899        recover old (wrong) results by setting noSlipFac = 2. in
900        seaice_calc_strainrates.F;
901      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
902      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
903        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
904      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
905    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
906      - new subroutines seaice_lsr_tridiagu/v
907      - introduce loop bounds i/jmin/max to be able to use a restricted
908        additive Schwarz method, but not used for now.
909      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
910      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
911    o OpenAD support
912       Reorganize S/R call for overall time-stepping loop to facilitate
913       OpenAD revolve loop replacement
914       (new S/R main_do_loop.F)
915    o model/src:
916      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
917      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
918        ADAMS_BASHFORTH2.
919    o pkg/cheapaml:
920      - add new parameter (default=F, same as before) to disable full domain
921        (including land) periodicity in X & Y dir.
922      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
923        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
924        into single S/R CHEAPAML_TIMESTEP.
925    
926    checkpoint64d (2013/02/17)
927    o pkg/monitor (angular momentum):
928      - do not add Eta contribution to the total AM if using rigid-lid;
929      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
930      - horizontal discretisation: compute Zonal wind contribution separately for
931        each component (instead of from cell centered averaged) and use the 4
932        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
933      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
934        FreeSurf) if using vectorInvariant momentum.
935    o model/src (horizontal grid):
936      - move initialisation of all horizontal grid arrays to null value
937        from specific horizontal grid S/R to main S/R INI_GRID;
938      - add 2 new arrays to project model C-grid velocity on to zonal direction
939        (similar to AngleCosC & -AngleSinC but at U and V point location) and
940        compute them in S/R CALC_GRID_ANGLES.
941    o pkg/seaice: replace a hard coded parameter by a runtime parameter
942        SEAICE_JFNK_tolIter
943    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
944        preconditioner for JFNK (run LSR into the overlaps as far as possible,
945        i.e OLx/y-2, but overwrite the solution in the overlaps)
946      - extend loop range in seaice_calc_viscosity
947      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
948      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
949      - slightly modify loops in tridiagonal solver lsr-preconditioner
950      - by default remove the extra exchange in seaice_preconditioner with a
951        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
952      - modify offline_exf_seaice so that old results without RAS are reproduced
953        for output.dyn_jfnk.txt
954      in seaice_fgmres.F (unrelated to RAS)
955      - add a cpp-flag option for a re-ordered mapping (potentially more
956        efficient), but because this changes the results, turn it off by
957        default
958      - replace the save statement by local common blocks
959    o utils/matlab:
960      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
961      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
962        instead of local script "load_cs.m".
963    o pkg/seaice:
964      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
965        to the scalarProductMetric and the unrolling. By chance this does not
966        change the verification experiment, because of the particular domain
967        decomposition
968    o pkg/diagnostics:
969      - change default missing_value from UNSET_RL to -999.
970    o pkg/layers: improve vectorization of layers_fluxcalc.F
971      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
972        time spent in this routine by more than a factor of 3 on an NEC-SX8
973      - step 2: replace search algorithm by a bisection algorithm found in
974        Press et al. Numerical Recipes in Fortran. This algorithm can be
975        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
976        For now, use this algorithm only for TARGET_NEC_SX defined.
977      - moved the search algorithm into a separate subroutine, that is kept
978        within the same file for automatic inlining.
979      - modified catching potential errors
980    o pkg/ecco:
981      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
982    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
983      - modifications for ALLOW_GENTIM2D_CONTROL
984      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
985      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
986      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
987      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
988    o model/src:
989      - account for moist thermodynamics in (dry) potential temperature equation;
990        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
991        and cpl_aim+ocn.
992      - also switch to standard compiler (gfortran, was using ifort previously)
993        for fizhi-cs experiments reference output.
994    o pkg/ctrl:
995      - 1st step toward generic time-varying control variable (2D) via CPP option
996        ALLOW_GENTIM2D_CONTROL
997      - note new namelist ctrl_nml_genarr in data.ctrl
998    o verification/global_ocean.cs32x15:
999      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
1000        thsice calling sequence and update "output.icedyn.txt" output file.
1001    o pkg/ptracers:
1002      - from Ryan A.: code to allow to restart a tracer at regular time interval
1003        specifying a reset frequency and a reset-phase (for each tracers).
1004    o pkg/thsice:
1005      - implement new sequence of calls for thsice+seaice:
1006          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
1007          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
1008      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
1009        in CPP_OPTIONS.h) to recover old sequence;
1010      - update diagnostics for Intermediate State thsice diagnostics: now filled
1011        just before advection (instead of just after advection in old sequence);
1012      - update output of experiment offline_exf_seaice (standard test);
1013      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
1014        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
1015    o pkg/aim_v23:
1016      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
1017      - use standard pkg/mdsio routines to read & write CO2 pickup file;
1018      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
1019      - Implement new sequence of calls for seaice advection (with thsice and
1020        seaice diffusion): do ice advection after ice-Thermodynamic (previously
1021        was done before); change aim_do_physics.F (split the bi,bj loops block);
1022      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
1023    o pkg/thsice:
1024      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
1025        where just seaice diffusion is used without seaice-dynamics.
1026    
1027    checkpoint64c (2013/01/18)
1028    o pkg/seaice:
1029      - add a parameter JFNKres_tFac that can replace JFNKres_t
1030        (= JFNKres_tFac*JFNKresidual before JFNK solver)
1031      - add a line search option to the JFNK solver
1032      - move update of u/vIce and computation of initial residual into a separate
1033        routine (same file); makes the code a little easier to read (?)
1034      - the line search requires computation of the residual and for some reason
1035        I cannot do the update of u/vIce at the beginning of the Newton loop
1036        without changing the results, so we move computation of the new residual
1037        also to the end of the Newton loop, even without the line search
1038    o pkg/mdsio:
1039      - write missing value (corresponding to undefined array value) to meta files;
1040        skip this if missing value is one (UNSET_RL would be a better value for the
1041        case of undefined missing value but it's current the default missing-value);
1042        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
1043    o pkg/exf & thsice:
1044      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
1045        diagnostics) even when SHORTWAVE_HEATING is #undef;
1046    o verification/cfc_example:
1047      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
1048        illustrate how to use it).
1049    o verification/offline_exf_seaice:
1050      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
1051        files to only one time-record.
1052      in input.thermo: narrow the 2 bands of low initial ice-concentration near
1053        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
1054        snapshot output; same mcPheePiston value as in thsice with
1055        surf-current=0.2m/s.
1056      in input.thsice: similar set-up as in input.thermo (channel with same seaice
1057        initial conditions).
1058    o verification/cfc_example:
1059      - update file "data" with more standard choice (default rotationPeriod,
1060        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
1061        set deltaTFreeSurf to deltaTtracer) and update the output.
1062    o pkg/layers:
1063      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
1064      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
1065    o verification/offline_exf_seaice:
1066      - set all {field}period to zero for constant-in-time forcing (not tested
1067        anywhere else).
1068    o verification/offline_exf_seaice:
1069      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
1070      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
1071    o model/src:
1072      - implement Finite-Volume method for (hydrostatic) presure gradient
1073        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
1074    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
1075      - In order to be compatible with the default EVP code, this requires changing
1076        the EVP code around a little; and because any small change immediately
1077        breaks the lab_sea.hb87 verification experiment, the reference output is
1078        updated two times (each time the remaining aggrement was only 2 digits):
1079        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
1080        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
1081        The adjoint test lab_sea.evp also needed to be updated.
1082      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
1083        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
1084        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
1085        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
1086        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
1087        kept obscure, because I need to test it a little more.
1088    o pkg/cheapaml:
1089      - fix few incorrect type (_RL/_RS) in subroutine calls.
1090    o pkg/seaice:
1091      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
1092        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
1093    o model/src:
1094      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
1095        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
1096        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
1097    o pkg/cheapaml:
1098      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
1099        update output of experiment cheapAML_box.
1100      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
1101        and set them only in one place (cheapaml_readparms.F).
1102      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
1103      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
1104        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
1105    o model/src/the_main_loop.F:
1106      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
1107    o pkg/seaice:
1108      - remove legacy branch code.
1109      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
1110    o verification/*/code*/SEAICE_OPTIONS.h:
1111      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
1112        SEAICE_CAP_HEFF).
1113    o pkg/cheapaml:
1114      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
1115        to load new forcing fields.
1116      - add missing "_d 0" where it's needed; + some editing (improve indentation).
1117      - remove switch to "-r8" compiler option (no longer needed) in verification
1118        cheapAML_box, keep same output (small trucation error differences).
1119    o verification/offline_exf_seaice:
1120      - add thermodynamics only test.
1121    o verification/cheapAML_box:
1122      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
1123        keep same output (same 14 digits for cg2d).
1124      - switch on "-r8" compiler option (some numerical values are missing
1125        the "_d 0") and update output (only 6 digits for cg2d were preserved).
1126    
1127    checkpoint64b (2012/12/24)
1128    o pkg/cheapaml:
1129      - remove un-used variables (Qnet,EmPmR) from pickup files.
1130      - store tendency of advected variables into cheapaml pickup file
1131        and fix the AB-2 restart.
1132    o verification/offline_exf_seaice and lab_sea adjoint:
1133      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
1134      - switch to 4 time steps in offline, consistent with lab_sea.
1135      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
1136      - update results after change of experiment seaice.
1137    o pkg/seaice:
1138      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
1139        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
1140        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
1141        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
1142    o model/src:
1143      - add run-time parameter to select CG2D solver minimum-residual solution
1144        (in case of a poor convergence).
1145    o pkg/seaice/seaice_lsr.F
1146      - move calculation of matrix coefficients into new
1147        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
1148        file; the main purpose of this change is to be able to reuse the code
1149        in S/R SEAICE_PRECONDITIONER
1150      - modify the computation of the residual so that the mass of sea-ice
1151        is not used twice; this simplifies the calculations, but since
1152        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
1153        not tested in testreport---this does not affect the testreport results.
1154    o verification/seaice_obcs:
1155      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
1156        verification/lab_sea/input.salt_plume; changes results/output.txt*
1157    o model/src:
1158      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
1159    o pkg/seaice:
1160      - improve description of parameters in seaice_fgmres.F and start
1161        cleaning up the code
1162      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
1163        second argument
1164      - add a metric based on grid cell area to SEAICE_SCALPROD; update
1165        results of offline_exf_seaice.dyn_jfnk
1166      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
1167    o pkg/aim_v23:
1168      - fix an other bug in dissipation heating (grid-cell area was missing).
1169    o model/src + pkg/seaice:
1170      - add global (multi-tile) linear solver for pair of tri-diagonal system
1171        along X and Y lines, respectively for U and V component.
1172        Note: 1) MPI and cube-exchange not yet coded.
1173            2) probably not accurate for poorly conditioned / large size problem.
1174      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
1175        default: not compiled and not used.
1176    o pkg/seaice:
1177      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
1178        introduce bi/bj loops and use global_sum_tile_rl instead of
1179        mpi_allreduce in seaice_fgmres.F
1180      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
1181      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
1182      - add a verification experiment for JFNK in offline_exf_seaice
1183    o verification:
1184      - change (for now, only fwd test) offline_exf_seaice experiment:
1185        use a re-entrant channel with idealized coastline (trapezoidal shape)
1186        at southern boundary to explore seaice dynamics and thermodynamics
1187        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
1188        secondary test (input.thsice) use thermodynamics only with SST relaxation.
1189      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
1190    o pkg/exf:
1191      - disable "sstExtrapol" when Nr=1
1192    o verification:
1193      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
1194        to test pkg/cheapaml.
1195    o pkg/aim_v23 & pkg/shap_filt:
1196      - fix dissipation heating (erroneous gravity multiplication factor).
1197    o pkg/seaice:
1198      - remove unused field pressPre from jfnk solver
1199      - rename two subroutines in seaice_preconditioner.F
1200    o eesupp/src:
1201       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
1202    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
1203       - remove wrong parts of the rhs and the lhs (were in there
1204         because I did not understand the concept of this preconditioner)
1205       - add an exchange between u- and v-sweep. This increases communication
1206         by a factor of two but improves the convergence of jfnk. Ideally,
1207         one would like the u- and v-sweep to be independent. So far within
1208         undocumented ifdefs
1209       - reorganize the extra computations for printing the residuals
1210    o tools/genmake2:
1211      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
1212        since it's not necessary (and was preventing to use MNC in some cases).
1213    
1214    checkpoint64a (2012/11/16)
1215    o pkg/autodiff:
1216      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
1217        autodiff_readparms.F no longer depends on calling order (within
1218        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
1219        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
1220        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
1221    o pkg/obcs:
1222      - adding tidal velocity forcing capability to obcs
1223        for usage example, see verification/seaice_obcs/input.tides
1224    o pkg/seaice:
1225      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
1226        SEAICE_LSRrelaxU/V
1227      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
1228    o pkg/aim_v23:
1229      - implement heating from friction (bottom friction and stratospheric drag).
1230    o pkg/shap_filt:
1231      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
1232        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
1233    o model/src:
1234      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
1235        time-constant addMass field from file (addMassFile);
1236      - support for heating due to friction (and Kinetic Energy dissipation):
1237        add option, run-time switch and 3-D field array + support code ; each pkg
1238        or S/R can add heating contribution (if there is a sink of KE); the sum is
1239        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
1240    o pkg/seaice:
1241      - complete merge of ITD code into seaice_growth.F
1242        from MITgcm_contrib/torge/itd/code/
1243        no verification so far, but Torge Martin tested
1244        "1-D test case and Beaufort set up;
1245        deliver okay results after 1 model year."
1246      - complete merge of SEAICE_SIZE.h into all relevant routines
1247      - move computation of eta at Z-points into calc_viscosities
1248        + introduce global field etaZ
1249        + add different methods for computing etaZ, for now the old
1250          method (simple averages of eta to Z-points) is hardwired
1251        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
1252          seaice_preconditioner
1253      - simplify computations for SEAICE_ZETA_SMOOTHREG
1254      - seaice_preconditioner:
1255        + replace one remaining press by pressLoc (mistake)
1256        + adjust printing of residuals
1257      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
1258        + add (SEAICE.h) and rename some counters (initiliased in
1259          seaice_init_fixed.F)
1260        + add _BEGIN/END_MASTER (myThid)  around print statements
1261        + print total number of iterations and failures over SEAICE_monFreq
1262          interval to STDOUT
1263      - move control over output-messages by fgmres to seaice_jfnk to save
1264        some operations
1265      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
1266        in order to make restarts with sol .ne. zero (fgmres with restarts)
1267        (seaice_jfnk.F, seaice_fgmres.F)
1268      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
1269        a serious convergence problem when open boundaries are involved
1270    o pkg/ggl90: fix computation of control volumes for the case of
1271      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
1272      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
1273    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
1274    o pkg/autodiff
1275      - Add inAdMode switch for SEAICEuseDYNAMICS:
1276        SEAICEuseDYNAMICSinAdMode
1277        (extend logic in ADAUTODIFF_INADMODE_SET)
1278    o pkg/seaice
1279      - Step 1 of merging ice-thickness distribution (ITD) code from
1280        MITgcm_contrib/torge/itd/ (author: Torge Martin)
1281        The code implements concept laid out in Thorndike et al. (1975);
1282        code is enabled via CPP flag SEAICE_ITD
1283        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
1284        code is not complete yet!!
1285      - SEAICE_SIZE.h now included in almost all seaice routines
1286    o verification (using seaice):
1287      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
1288        global_ocean.cs32x15.seaice ; update results.
1289      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
1290      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
1291        offline_exf_seaice (previously compiling B-grid).
1292    o pkg/exf:
1293      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
1294        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
1295        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
1296    o pkg/layers (adjust changes from Sept 19):
1297      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
1298        this allows to remove "layers_maxNum" dimension from all layers arrays.
1299    o pkg/layers (adjust changes from Sept 19):
1300      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
1301      - snap-shot extended to all type of layers (not just the 1rst type);
1302      - remove layers variables when corresponding CPP option is undef.
1303    o pkg/layers:
1304      - rename pkg/layers variable and add new output (layer exist & un-weighted
1305        velocity in layer)
1306    o pkg/seaice:
1307      - simplify (?) ocean-drag coefficent computations by using
1308        the same routine in all three solvers (saves some code lines)
1309      - remove global fields DRAGA and DRAGS from C-grid code and
1310        declare them locally in lsr.F (the only place where they are
1311        still used)
1312      - update AD output of lab_sea.evp (very sensitive anyway).
1313    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
1314      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
1315      and SEAICEuseJFNK=.true. A few things to note:
1316      - involves a FGMRES, that is parallel but very inefficient,
1317        because of many scalar products (global sums) in the Gram-Schmidt
1318        orthogonalization method. Needs to be replaced. Original code
1319        from J.-F. Lemieux
1320      - preconditioner for FGMRES is a stripped down version of LSOR
1321      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
1322        preconditioner. For the preconditioner, the default is set to 10.
1323      - Jacobian times vector is computed with finite differences
1324      - marginally related to JFNK-solver: add a smooth regularization for
1325        zeta with tanh that will improve convergence (Lemieux and Tremblay,
1326        2009) for any implicit solver (not implemented for EVP because EVP
1327        does not need this regularization in the first place). Define
1328        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
1329    o eesupp/src:
1330      - check in genmake2 that intrinsic S/R flush is available.
1331      - add S/R to flush IO unit (if intrinsic S/R flush is available)
1332      - flush standard & error msg unit before MPI termination
1333      - if debugMode, flush IO unit after printing msg
1334    o pkg/ctrl:
1335      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
1336        to ctrl_set_unpack_xyz.
1337    
1338    checkpoint64 (2012/10/09)
1339    o pkg/shelfice
1340      - in mom_fluxform.F, mom_vecinv.F:
1341        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
1342        Bug fix KappaRU -> KappaRV
1343        does not change verification/isomip but may change other setups
1344        (presumably constant KappaRU=KappaRV)
1345      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
1346    o pkg/obcs:
1347      - fixed some indexing bugs in obcs_seaice_sponge.F
1348      - added obcs relaxation subroutines for HSALT and HSNOW
1349      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
1350    o pkg/seaice:
1351      - add "multicategory" parameterization for snow in analogy to ice,
1352        default is off for now.
1353    o pkg/obcs:
1354      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
1355        see verification/seaice_obcs/input.seaiceSponge for example application.
1356      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
1357        index setting by master-thread. This fix multi-threads Pb in previous modifs.
1358    o pkg/layers :
1359      - add diagnostics to pkg/layers
1360      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
1361        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
1362    o pkg/generic_advdiff/gad_implicit_r.F :
1363      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
1364    o pkg/seaice/seaice_growth.F:
1365      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
1366    o pkg/obcs:
1367      - change default setting of OBCS_UVICE_OLD from defined to undef;
1368      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
1369        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
1370      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
1371      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
1372        with Southern & Western OB at a tile edge (at least in a simple set-up).
1373    o pkg/obcs:
1374      - change settings of OB index in case OB coincides with tile edge (shared by
1375        2 tiles), so that common OB location is registered by both tiles (instead of
1376        only 1). However, for Southern and Western OB, index value = 0 is not
1377        recognized as valid OB index (=default null value) and needs to be fixed.
1378      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
1379      - new parameter "OB_indexNone" for null index value (for now, still zero)
1380        to replace hard-coded null index value of zero.
1381    o pkg/exch2:
1382      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
1383        always check buffer-size (but outside the loop); move checking for valid
1384        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
1385        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
1386    o pkg/ctrl (pack & unpack):
1387      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
1388        (locally defined) for different variables (+ remove the variable-specific
1389        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
1390        (to be extended to other local file names in ctrl.h).
1391    o pkg/flt:
1392      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
1393    o pkg/mdsio:
1394      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
1395    o tools/genmake2:
1396      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
1397        (added by Alistair in version 1.51 for building without make depend);
1398      - remove Header files list (H_SRC_FILES) from the dependence of targets
1399         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
1400        place in version 1.23): this save going through staf when unrelated header
1401        file has been modified.
1402       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
1403        "make depend" step, still need to do "make links" before "make adtaf".
1404    o eesupp/src (+ few pkg src files) & genmake2:
1405      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
1406      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
1407      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
1408         upper/lower case ; account for space between "#" and undef/define)
1409    o pkg/flt (with exch2):
1410      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
1411      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
1412    
1413    checkpoint63s (2012/09/05)
1414    o pkg/ecco:
1415      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
1416      - add more relevant #ifdef ALLOW_SMOOTH ones.
1417      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
1418    o pkg/ctrl:
1419      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
1420        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
1421      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
1422        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
1423        ctrlSmoothCorrel3D (new).
1424        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
1425      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
1426      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
1427        controls when useAtmWind, and vice versa.
1428      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
1429      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
1430          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
1431      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
1432          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
1433      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
1434        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
1435    o pkg/smooth:
1436      - remove un-necessary includes.
1437      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
1438        Those CPP options were never defined, and not necessary.
1439    o model/src:
1440      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
1441      - standard treatment of useSMOOTH.
1442    o pkg/autodiff:
1443      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
1444        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
1445    o pkg/exch2:
1446      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
1447        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
1448      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
1449        and tiles to process mapping.
1450      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
1451        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
1452        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
1453        from w2_eeboot.F to w2_readparms.F.
1454    o eesupp/src:
1455      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
1456        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
1457        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
1458      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
1459        is defined (remove condition on usingMPI) to match cases where MPI_INIT
1460        has been called.
1461      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
1462      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
1463        (so that on 1 proc, get same myPid independently of usingMPI)
1464      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
1465        useCubedSphereExchange with EXCH-1 (safer).
1466      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
1467    o pkg/ggl90:
1468      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
1469        used in ALLOW_GGL90_SMOOTH code.
1470    o pkg/flt:
1471      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
1472        floats at the Southern end of the domain).
1473    o eesupp/inc:
1474      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
1475        but not used (and not to be used) anywhere, just for documentation.
1476    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
1477      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
1478        a) can damage previously written records in any other multi-record files.
1479        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
1480    o tools/genmake2:
1481      - define variable MAKE within Makefile and use it in place of 'make';
1482      - update AD_CONFIG.h (if needed) before building any of the executable
1483        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
1484        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
1485      - always print usual warning comment 'this file is automatically generated'
1486        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
1487    o pkg/cheapaml:
1488      - updated to correspond to the code used in accepted paper (Nico Wienders).
1489    o pkg/exf:
1490        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
1491        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
1492        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
1493    o pkg/exf, autodiff, ctrl, ecco and seaice:
1494        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
1495    o pkg/ctrl, ecco:
1496        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
1497        Depending on useAtmWind, one is inactive, and the other is active (see
1498        exf_getffields.F/exf_getsurfacefluxes.F).
1499    o tools/genmake2:
1500      - improve error msg when failing in 2nd test of check_for_broken_Ff
1501      - fix option '-makefile' short-name (-mf according to genmake2 -help)
1502      - source local config file "genmake_local" just after processing the genmake2
1503        command arguments (previously done before processing arg).
1504    o pkg/grdchk:
1505      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
1506        to this routine from cost_final has been dropped in g_cost_final)
1507      - improve printed information (more explicit msg, no longer using "print *,"
1508         fix fcpertminus printed value).
1509    o model/src:
1510      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
1511        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
1512        this prevents getting cost-funct reset in adinitialise_varia recomputations.
1513    o pkg/dic:
1514      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
1515        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
1516    o pkg/grdchk:
1517      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
1518      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
1519    o pkg/autodiff/ctrl/grdchk :
1520      - attempt to sort out what works and what does not,
1521        with regard to I/O, and to warn/stop accordingly.
1522    o pkg/grdchk:
1523      - attempt to fix grdchk in the case of useSingleCpuIO.
1524      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
1525       statements were moved from grdchk_main.F and into
1526       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
1527      - a global sum is applied to record numbers icvrec/layer
1528       out of grdchk_loc so that they be passed to I/O routines.
1529    o pkg/smooth:
1530      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
1531        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
1532    o verification/testreport:
1533      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
1534      - can also use compressed (gzip) reference output file;
1535      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
1536        to be easier to collect by testreport.
1537      - update existing TLM output (half out-of-date by more than 3 yrs).
1538      - report NETCDF & LAPACK settings (from genmake2) in output dir.
1539      - report run-time in each individual summary (previously only for AD test);
1540        for TLM test, add also TAF version.
1541      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
1542    
1543    checkpoint63r (2012/08/15)
1544    o tools/genmake2:
1545      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
1546    o pkg/ecco/ecco_cost_final.F :
1547      - fix fc print statements (to stdout and costfunction0000) so
1548        that the printed value is always after the global sum.
1549    o pkg/seaice/seaice_dynsolver.F :
1550      - fix ice strength assymptote at SEAICE_area_max<1
1551        (no change for the standard case of SEAICE_area_max=1)
1552  o some cleaning:  o some cleaning:
1553    - pkg source files: ensure that all *.F files from each pkg included the    - pkg source files: ensure that all *.F files from each pkg included the
