4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjoint with OpenAD:
8      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
9        package openad.  This package has to be compiled for all runs with OpenAD
10        instead of specifying code_oad_all as a modification directory.
11      - link the fortran templates from tools/OAD_support to the build directory
12        for preprocessing to avoid conflicts between different setups compiled
13        simultaneously and simplify cleanup.
14    o pkg/exf:
15      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
16        main model or other pkgs are exchanged in EXF_MAPFIELDS).
17    o model/src:
18      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
19        (similar to do_fields_blocking_exchanges.F).
20    o tools/genmake2:
21      - remove TAF output src code just before calling staf (when not doing a fresh
22        built, will stop if things go wrong with staf).
23      - fix target "adobj" (left from TAF version-2 transition)
24    o pkg/diagnostics:
25      - add a parameter to track the status of pkg/diagnostics activation;
26        this replace/extend the use of logical param "settingDiags" (to check
27        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
28        New S/R to print error message and stop when pkgStatus is not right.
29      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
30    
31    checkpoint64m (2013/08/13)
32    o model/inc:
33      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
34        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
35    o pkg/kpp & aim_v23:
36      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
37    o pkg/seaice:
38      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
39        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
40      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
41    o eesupp/src:
42      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
43        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
44    o switch to TAF version-2:
45      - add flow directives to "freeze" naming convention for ad-routines that
46        are used in I/O routines of adjoint state and associated common blocks
47        that are used in adcommon.h (backward compatible with version-1)
48      - update all ad-optfiles (in tools/adjoint_options + few local to some
49        verification exp) to switch to latest TAF version (currently 2.5.5);
50        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
51        out except for diva).
52      - the major change with TAF version-2 is that both the differentiated
53        routines and the forward routines (new) are returned as part of the TAF
54        output source code. Update genmake2 accordingly.
55      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
56        with version-2 when compared to TLM or FWD gradient); other experiments
57        output show minor changes (machine truncation level); update the few AD &
58        TLM output with 12 matching digits only (some prior to version-2 switch).
59    
60    checkpoint64l (2013/08/05)
61    o model/src:
62      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
63      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
64        when using TAF but only if using OpenAD.
65    o pkg/mom_common+fluxform+vecinv:
66      - always set horiz. viscosity arrays to background value before calling
67        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
68        only when using variable horiz. viscosity (useVariableVisc=T);
69      - simplify mom_vecinv.F (only 1 block for momViscosity).
70    o pkg/mom_common: variable horiz. viscosity in NH code
71      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
72        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
73      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
74        useBiharmonicVisc & useVariableVisc.
75      - fix old bug (already in 1rst implementation of variable horizontal viscosity
76        in calc_gw.F, version 1.27, 2006/06/20):
77        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
78        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
79      - change background horiz viscosity in vertical momentum (gW) to always be
80        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
81        any type of variable viscosity, e.g., viscAh/4Grid)
82      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
83        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
84        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
85        default viscAh,viscA4 is zero).
86    o model/src:
87      - extend length of drC & recip_drC from Nr to Nr+1.
88    o Divided Adjoint (DIVA) with MPI:
89      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
90      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
91        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
92    
93    checkpoint64k (2013/07/23)
94    o tools/OAD_support:
95      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
96        and remove it from genmake2.
97    o tools/build_options:
98      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
99        MPI_HEADER_FILES list (let genmake2 find the missing headers)
100    o verification/halfpipe_streamice:
101      - change to driving stress formulation; update both Fwd & AD output.
102    o tools/genmake2 and Divided Adjoint with MPI:
103      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
104      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
105      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
106        Makefile, which is set by genmake2, and check which mpi-headers are needed.
107        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
108      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
109    o testreport:
110      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
111        perform additional runs (number of additional runs is "add_DIVA_runs" taken
112        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
113    o verification/lab_sea (AD test):
114      - change to test Divided Adjoint Run in this set-up (both standard AD test
115        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
116    o pkg atm_ & ocn_compon_interf:
117      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
118        staggerTimeStep implementation) and disable (retired) corresponding
119        parameter.
120    o pkg/offline:
121      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
122      - add S/R OFFLINE_CHECK to print offline parameter summary
123        and stop if loading a file that is not used;
124      - enable to calculate GMRedi tensor, KPP mixing and convective index
125        when the corresponding file(s) is/are not specified (but pkg is used).
126      - comment out resetting of monitorFreq (to endTime) since it still useful
127        for monitoring CFL numbers and checking offline fields.
128    o OpenAD:
129      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
130        smaller standard output) and generate new (smaller) output (on baudelaire
131        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
132    o model/src:
133      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
134        (where external_forcing_adjust was called) and change list of arguments;
135      - merge external_forcing_adjust.F into external_forcing_surf.F
136      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
137        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
138        previously in file "balance_relax.F", now removed); remove corresponding
139        arrays in FFIELDS.h.
140      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
141        a hack for getting back surfaceForcingS (loaded from file) when using
142        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
143      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
144        (was getting only 11 digits for AD-grad, due to different truncation
145         error in AD code).
146    
147    checkpoint64j (2013/07/04)
148    o pkg/offline:
149      - to enable the use of other features with pkg offline (e.g., obcs),
150        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
151      - comment out "allowFreezing" (now active) in 2 offline testing exp.
152    o pkg/exf ALLOW_RUNOFTEMP
153      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
154      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
155      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
156    o pkg/atm_phys:
157      - allows to add some damping on uVel,vVel (strength only function of k).
158    o verification, ad-tests:
159      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
160        global_ocean_ebm and offline_exf_seaice.thsice.
161    o verification/halfpipe_streamice:
162      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
163        flux input boundary conditions to be ignored; a fix for this bug changed
164        verification results for forward test.
165      - add adjoint test.
166    o pkg/ptracers:
167      - allow to restart without SOM pickup (resetting SOM to zero).
168    o pkg/gmredi:
169      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
170      - It uses mixing length theory and suppression by steering level effects to
171        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
172        to JPO, for more details).
173      - It also uses the diffusivity to calculate an eddy induced streamfunction
174        based on a PV closure (rather than a buoyancy closure as in GM).
175      - New files added to pkg/gmredi:
176        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
177          induced overturning streamfunction (called from gmredi_calc_tensor)
178        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
179          for use in gmredi_k3d
180        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
181          the eddy diffusivity
182    
183    checkpoint64i (2013/06/18)
184    o pkg/cheapaml:
185      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
186        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
187        with pkg/cheapaml.
188    o utils/python: add subpackage for cubed sphere function, first example is
189        simple cs.pcol to plot 2D fields on a map
190    o pkg/streamice:
191      - This is a new package in MITgcm, which solves dynamic equations for ice
192         sheets and ice streams
193      - At the moment it is independent of atmosphere/ocean dynamics, or any
194        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
195        ed that this will change)
196      - There is a new verification exercise that tests it, halfpipe_streamice,
197        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
198        rectangular embayment
199      - halfpipe_streamice is forward-only for now, will have TAF test soon
200      - for questions, email dgoldber@mit.edu
201    o pkg/thsice:
202      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
203        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
204      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
205         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
206      - allow precip from pkg/cheapaml to make snow over seaice.
207    o pkg/cfc:
208      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
209      - remove atmos CFC 2-D arrays from common bloc (now local variables)
210      - change some hard-coded constant to run time parameter for reading and
211        and interpolating atmospheric CFC ; keep same default as previously.
212      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
213      - put arguments in standard order: myTime, myIter, myThid
214      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
215        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
216      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
217      - new routine to print summary of CFC params and check for consistency.
218    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
219      similar to thsice_advdiff.
220      Note that for the B-grid case the routine parameters uc/vc are overwritten.
221    o pkg/cfc:
222      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
223        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
224      - fix interpolation of atmphspheric CFC between Sorthern and Northern
225        hemisphere value.
226    o pkg/seaice:
227      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
228    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
229                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
230      - requires an additional time level that is stored in the pickup
231      - you can start with AB2 from a pickup without this time level with
232        pickupStrictlyMatch = .false.
233    
234    checkpoint64h (2013/05/26)
235    o pkg/cheapaml:
236      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
237        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
238      - consistent treatment of uWind,vWind location: assume everywhere in
239        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
240        (Note: was already the case for Tair,Qair advection);
241        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
242      - compute diabatic forcing only in the interior (excluding overlap regions)
243      - fill in array "Qsw" (for short-wave heating);
244      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
245        before any update (consistent with MITgcm state var diagnostics);
246      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
247        non periodic ; + adjusted for uWind,vWind (C-grid).
248    o pkg/seaice:
249      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
250        add explicitly pkg/exf in experiments that currently use pkg/seaice.
251      - allows to compile pkg/seaice without pkg/exf.
252    o tools/OAD_support:
253      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
254        of array "ourStepOf" in function rvNextAction (revolve.F90).
255    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
256      - change pkg name (to be used with other atmospheric physics pkg)
257        but by-pass CVS when making the new pkg so that we keep the CVS history.
258    o pkg/offline:
259      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
260        (previously called from pkg/dic_surfforcing_init.F)
261    o model/src:
262      - re-order sequence of calls within packages_init_variables.F, using
263        standard order, except for:
264         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
265         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
266    o new pkg: atm_phys
267      - add entry point and source code (previously in contrib
268          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
269        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
270      - re-order sequence of calls within packages_readparms.F,
271         packages_init_fixed.F and packages_write_pickup.F
272        (but skip packages_init_variables.F because of TAF issues).
273      - update contrib/*/atm_gray/ experiment.
274    o pkg/seaice (ITD code):
275      - simplify and fix the writing of pickup-files for ITD case
276    o pkg/seaice (ITD code):
277      - introduce floe size dependent lateral melt for ITD case;
278      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
279      - update seaice_itd experiment main output.
280    o pkg/thsice:
281      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
282        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
283        changed accordingly pkg/atm2d.
284    
285    checkpoint64g (2013/05/01)
286    o pkg/exf ALLOW_RUNOFTEMP
287      - if defined,  river and glacier runoff temperature can be read-in from
288        runoftempfile; runoftempfile needs to have same format as runofffile
289    o pkg/thsice (& pkg/bulk_force):
290      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
291        for energy content of Precip + RunOff & Evap (like with pkg/exf).
292      - change computation domain to always be the interior (without overlap).
293      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
294    o verification/tutorial_global_oce_biogeo:
295      - add preliminary OpenAD setup (still has problems)
296    o pkg/seaice:
297      - turn some parameters for choosing the convergence criterion of
298        the inexact Newton method (JFNK) into runtime parameters for convenience
299      - clean up seaice_calc_viscosities.F: remove/retire two options for
300        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
301        the results of lab_sea/input because a division has been replaced by
302        a multiplication with the reciprocal (sumNorm)
303      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
304        convergence of solver (changes results, of course), and to test some
305        new features
306    o model/src:
307      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
308      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
309      - move forcing adjustment (balancing surface forcing) in specific S/R
310        where might also be applied exchanges (if needed) to forcing arrays.
311    o pkg/shelfice:
312      - allow to specify the Ice-Shelf mass per unit area (instead of
313        shelficeLoadAnomaly) and do the conversion from one to the other
314      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
315        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
316        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
317        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
318      - update isomip experiment forward output (get machine truncation error
319        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
320    o verification/offline_exf_seaice:
321      revise data.seaice in input.thermo and input_ad and update results accordingly
322        HO = 0.2, SEAICE_areaLossFormula = 2,
323        SEAICE_growMeltByConv = .TRUE.,
324        SEAICE_doOpenWaterMelt = .TRUE.,
325      Improve consistency with input.thsice and fix the spurious 500m ice corners
326    o verification/global_ocean.cs32x15:
327      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
328        in icedyn (thsice+seaice-dyn) test and update output.
329    o verification/offline_exf_seaice:
330      - adjust list of tested variables (with testreport) and update
331        standard test output with better slection of monitored fields.
332    o pkg/cd_code:
333      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
334        experiment lab_sea.hb87
335    o tools/genmake2:
336      - change default makedepend from the system default to tools/xmakedepend:
337        When no makedepend is specified, select tools/xmakedepend it the test pass,
338        otherwise select the system default (if exist and pass the test) or
339        try to build cyrus-makedepend ; stop if none of the 3 works.
340    o pkg/exf & pkg/thsice:
341      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
342        for energy content of Precip + RunOff & Evap. Assumes:
343       1) Rain has same temp as Air.
344       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
345       3) Run-Off comes at the temp of surface water (with same Cp)
346       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
347        put directly into Latent Heat flux & should use water-vapor heat capacity.
348       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
349        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
350    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
351        (compile when SEAICE_ALLOW_JFNK is defined)
352    o pkg/thsice:
353      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
354        implementation): move THSICE_AVE call after the advection (called directly
355        from thsice_do_advect.F).
356    o verification/global_ocean.90x40x15 and OpenAD:
357      New experiment for OpenAD is identical to the one in input_ad except that
358        multiDimAdvection=.FALSE.,
359      There is still an issue with this.
360    o pkg/thsice:
361      - account for ice velocity (ocean relative velocity) in turbulent heat flux
362        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
363        and offline_exf_seaice (main test).
364    
365    checkpoint64f (2013/03/31)
366    o verification/OpenAD:
367      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
368    o verification/isomip, pkg/shelfice and OpenAD:
369      - add OpenAD setup to this exp and make shelfice package work with OpenAD
370    o verification/tutorial_global_oce_biogeo:
371      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
372    o verification/offline_exf_seaice:
373      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
374    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
375      - add OpenAD setup to this exp and make ptracers package work with OpenAD
376    o pkg/seaice/seaice_evp.F:
377       mask the asymmetric contribution of the ice-ocean stress (when
378       the turningAngle is non-zero) over open water to avoid stripes
379       in the EVP-solutions after many EVP-substeps. This does not change
380       the verification experiment (because turningAngle=0 in that experiment),
381       but will affect other EVP solutions with turningAngle.ne.0
382    o verification, AD & TLM output:
383      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
384        additions and multiplications which affect results at machine truncation
385        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
386        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
387        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
388        digits of matching.
389    o pkg/seaice:
390       modify lsr-algorithm so that it vectorizes AND converges by using a
391       "zebra" method: split vector loop into two with step size 2; this
392       solves a general convergence problem for the JFNK solver on a vector
393       computer. It has the potential to even improve convergence for
394       non-vector machines, but it does change the results so it is turned
395       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
396       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
397    
398    checkpoint64e (2013/03/05)
399    o pkg/ecco and several verification experiments:
400       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
401       from ecco package, and revert to unified routine in model/src/
402       Adjust verification experiments accordingly, especially gloal_oce_llc90
403       Should conclude long-standing work by Gael to reconsile the_main_loop with
404       ECCO and will enable OpenAD's revolve loop in ECCO setup.
405    o pkg/generic_advdiff:
406      - implement compressible flow method for multi-dim advection (similar to
407        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
408        TAF generates many recomputations) to use it; no yet coded with implicit
409        vertical advection.
410      - change experiment advect_cs (new output) and advect_xy (same output)
411        to test compressible flow multi-dim advection.
412    o pkg/generic_advdiff:
413      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
414        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
415    o pkg/seaice:
416      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
417        bug affects two verification experiments (lab_sea and lab_sea.hb87),
418        recover old (wrong) results by setting noSlipFac = 2. in
419        seaice_calc_strainrates.F;
420      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
421      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
422        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
423      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
424    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
425      - new subroutines seaice_lsr_tridiagu/v
426      - introduce loop bounds i/jmin/max to be able to use a restricted
427        additive Schwarz method, but not used for now.
428      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
429      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
430    o OpenAD support
431       Reorganize S/R call for overall time-stepping loop to facilitate
432       OpenAD revolve loop replacement
433       (new S/R main_do_loop.F)
434    o model/src:
435      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
436      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
437        ADAMS_BASHFORTH2.
438    o pkg/cheapaml:
439      - add new parameter (default=F, same as before) to disable full domain
440        (including land) periodicity in X & Y dir.
441      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
442        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
443        into single S/R CHEAPAML_TIMESTEP.
444    
445    checkpoint64d (2013/02/17)
446    o pkg/monitor (angular momentum):
447      - do not add Eta contribution to the total AM if using rigid-lid;
448      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
449      - horizontal discretisation: compute Zonal wind contribution separately for
450        each component (instead of from cell centered averaged) and use the 4
451        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
452      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
453        FreeSurf) if using vectorInvariant momentum.
454    o model/src (horizontal grid):
455      - move initialisation of all horizontal grid arrays to null value
456        from specific horizontal grid S/R to main S/R INI_GRID;
457      - add 2 new arrays to project model C-grid velocity on to zonal direction
458        (similar to AngleCosC & -AngleSinC but at U and V point location) and
459        compute them in S/R CALC_GRID_ANGLES.
460    o pkg/seaice: replace a hard coded parameter by a runtime parameter
461        SEAICE_JFNK_tolIter
462    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
463        preconditioner for JFNK (run LSR into the overlaps as far as possible,
464        i.e OLx/y-2, but overwrite the solution in the overlaps)
465      - extend loop range in seaice_calc_viscosity
466      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
467      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
468      - slightly modify loops in tridiagonal solver lsr-preconditioner
469      - by default remove the extra exchange in seaice_preconditioner with a
470        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
471      - modify offline_exf_seaice so that old results without RAS are reproduced
472        for output.dyn_jfnk.txt
473      in seaice_fgmres.F (unrelated to RAS)
474      - add a cpp-flag option for a re-ordered mapping (potentially more
475        efficient), but because this changes the results, turn it off by
476        default
477      - replace the save statement by local common blocks
478    o utils/matlab:
479      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
480      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
481        instead of local script "load_cs.m".
482    o pkg/seaice:
483      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
484        to the scalarProductMetric and the unrolling. By chance this does not
485        change the verification experiment, because of the particular domain
486        decomposition
487    o pkg/diagnostics:
488      - change default missing_value from UNSET_RL to -999.
489    o pkg/layers: improve vectorization of layers_fluxcalc.F
490      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
491        time spent in this routine by more than a factor of 3 on an NEC-SX8
492      - step 2: replace search algorithm by a bisection algorithm found in
493        Press et al. Numerical Recipes in Fortran. This algorithm can be
494        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
495        For now, use this algorithm only for TARGET_NEC_SX defined.
496      - moved the search algorithm into a separate subroutine, that is kept
497        within the same file for automatic inlining.
498      - modified catching potential errors
499    o pkg/ecco:
500      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
501    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
502      - modifications for ALLOW_GENTIM2D_CONTROL
503      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
504      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
505      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
506      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
507    o model/src:
508      - account for moist thermodynamics in (dry) potential temperature equation;
509        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
510        and cpl_aim+ocn.
511      - also switch to standard compiler (gfortran, was using ifort previously)
512        for fizhi-cs experiments reference output.
513    o pkg/ctrl:
514      - 1st step toward generic time-varying control variable (2D) via CPP option
515        ALLOW_GENTIM2D_CONTROL
516      - note new namelist ctrl_nml_genarr in data.ctrl
517    o verification/global_ocean.cs32x15:
518      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
519        thsice calling sequence and update "output.icedyn.txt" output file.
520    o pkg/ptracers:
521      - from Ryan A.: code to allow to restart a tracer at regular time interval
522        specifying a reset frequency and a reset-phase (for each tracers).
523    o pkg/thsice:
524      - implement new sequence of calls for thsice+seaice:
525          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
526          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
527      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
528        in CPP_OPTIONS.h) to recover old sequence;
529      - update diagnostics for Intermediate State thsice diagnostics: now filled
530        just before advection (instead of just after advection in old sequence);
531      - update output of experiment offline_exf_seaice (standard test);
532      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
533        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
534    o pkg/aim_v23:
535      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
536      - use standard pkg/mdsio routines to read & write CO2 pickup file;
537      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
538      - Implement new sequence of calls for seaice advection (with thsice and
539        seaice diffusion): do ice advection after ice-Thermodynamic (previously
540        was done before); change aim_do_physics.F (split the bi,bj loops block);
541      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
542    o pkg/thsice:
543      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
544        where just seaice diffusion is used without seaice-dynamics.
545    
546    checkpoint64c (2013/01/18)
547    o pkg/seaice:
548      - add a parameter JFNKres_tFac that can replace JFNKres_t
549        (= JFNKres_tFac*JFNKresidual before JFNK solver)
550      - add a line search option to the JFNK solver
551      - move update of u/vIce and computation of initial residual into a separate
552        routine (same file); makes the code a little easier to read (?)
553      - the line search requires computation of the residual and for some reason
554        I cannot do the update of u/vIce at the beginning of the Newton loop
555        without changing the results, so we move computation of the new residual
556        also to the end of the Newton loop, even without the line search
557    o pkg/mdsio:
558      - write missing value (corresponding to undefined array value) to meta files;
559        skip this if missing value is one (UNSET_RL would be a better value for the
560        case of undefined missing value but it's current the default missing-value);
561        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
562    o pkg/exf & thsice:
563      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
564        diagnostics) even when SHORTWAVE_HEATING is #undef;
565    o verification/cfc_example:
566      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
567        illustrate how to use it).
568    o verification/offline_exf_seaice:
569      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
570        files to only one time-record.
571      in input.thermo: narrow the 2 bands of low initial ice-concentration near
572        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
573        snapshot output; same mcPheePiston value as in thsice with
574        surf-current=0.2m/s.
575      in input.thsice: similar set-up as in input.thermo (channel with same seaice
576        initial conditions).
577    o verification/cfc_example:
578      - update file "data" with more standard choice (default rotationPeriod,
579        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
580        set deltaTFreeSurf to deltaTtracer) and update the output.
581    o pkg/layers:
582      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
583      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
584    o verification/offline_exf_seaice:
585      - set all {field}period to zero for constant-in-time forcing (not tested
586        anywhere else).
587    o verification/offline_exf_seaice:
588      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
589      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
590    o model/src:
591      - implement Finite-Volume method for (hydrostatic) presure gradient
592        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
593    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
594      - In order to be compatible with the default EVP code, this requires changing
595        the EVP code around a little; and because any small change immediately
596        breaks the lab_sea.hb87 verification experiment, the reference output is
597        updated two times (each time the remaining aggrement was only 2 digits):
598        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
599        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
600        The adjoint test lab_sea.evp also needed to be updated.
601      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
602        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
603        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
604        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
605        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
606        kept obscure, because I need to test it a little more.
607    o pkg/cheapaml:
608      - fix few incorrect type (_RL/_RS) in subroutine calls.
609    o pkg/seaice:
610      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
611        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
612    o model/src:
613      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
614        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
615        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
616    o pkg/cheapaml:
617      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
618        update output of experiment cheapAML_box.
619      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
620        and set them only in one place (cheapaml_readparms.F).
621      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
622      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
623        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
624    o model/src/the_main_loop.F:
625      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
626    o pkg/seaice:
627      - remove legacy branch code.
628      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
629    o verification/*/code*/SEAICE_OPTIONS.h:
630      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
631        SEAICE_CAP_HEFF).
632    o pkg/cheapaml:
633      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
634        to load new forcing fields.
635      - add missing "_d 0" where it's needed; + some editing (improve indentation).
636      - remove switch to "-r8" compiler option (no longer needed) in verification
637        cheapAML_box, keep same output (small trucation error differences).
638    o verification/offline_exf_seaice:
639      - add thermodynamics only test.
640    o verification/cheapAML_box:
641      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
642        keep same output (same 14 digits for cg2d).
643      - switch on "-r8" compiler option (some numerical values are missing
644        the "_d 0") and update output (only 6 digits for cg2d were preserved).
645    
646    checkpoint64b (2012/12/24)
647    o pkg/cheapaml:
648      - remove un-used variables (Qnet,EmPmR) from pickup files.
649      - store tendency of advected variables into cheapaml pickup file
650        and fix the AB-2 restart.
651    o verification/offline_exf_seaice and lab_sea adjoint:
652      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
653      - switch to 4 time steps in offline, consistent with lab_sea.
654      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
655      - update results after change of experiment seaice.
656    o pkg/seaice:
657      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
658        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
659        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
660        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
661    o model/src:
662      - add run-time parameter to select CG2D solver minimum-residual solution
663        (in case of a poor convergence).
664  o pkg/seaice/seaice_lsr.F  o pkg/seaice/seaice_lsr.F
665      - move calculation of matrix coefficients into new
666        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
667        file; the main purpose of this change is to be able to reuse the code
668        in S/R SEAICE_PRECONDITIONER
669    - modify the computation of the residual so that the mass of sea-ice    - modify the computation of the residual so that the mass of sea-ice
670      is not used twice; this simplyfies the calculations, but since      is not used twice; this simplifies the calculations, but since
671      the residual is never used except when LSR_mixIniGuess.ge.4---and this is      the residual is never used except when LSR_mixIniGuess.ge.4---and this is
672      not tested in testreport---this does not affect the testreport results.      not tested in testreport---this does not affect the testreport results.
