5      ==============================      ==============================
6    
7    checkpoint64n (2013/08/26)
8    o verification/halfpipe_streamice:
9      - change to matrix construction; update both Fwd & AD output.
10    o verification/tutorial_tracer_adjsens:
11      - OpenAD test: switch to vector-invariant momentum since fluxform with
12        rStar causes problems with OpenAD; update output.
13    o tools:
14      - genmake2: define a common prefix for all temp-file names ; move them
15        to local /tmp disk (but would be easy to move them back);
16      - xmakedepend: apply the same switch for temp-files.
17    o pkg/offline:
18      - changes for use with rStar (NLFS): assume that we continue to provide
19        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
20        output files) and apply r* scaling at each time-step (function of the time
21        varying Eta field); use normal pickup files (needed for restart with NLFS).
22    o adjoint with OpenAD:
23      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
24        package openad.  This package has to be compiled for all runs with OpenAD
25        instead of specifying code_oad_all as a modification directory.
26      - link the fortran templates from tools/OAD_support to the build directory
27        for preprocessing to avoid conflicts between different setups compiled
28        simultaneously and simplify cleanup.
29    o pkg/exf:
30      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
31        main model or other pkgs are exchanged in EXF_MAPFIELDS).
32    o model/src:
33      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
34        (similar to do_fields_blocking_exchanges.F).
35    o tools/genmake2:
36      - remove TAF output src code just before calling staf (when not doing a fresh
37        built, will stop if things go wrong with staf).
38      - fix target "adobj" (left from TAF version-2 transition)
39    o pkg/diagnostics:
40      - add a parameter to track the status of pkg/diagnostics activation;
41        this replace/extend the use of logical param "settingDiags" (to check
42        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
43        New S/R to print error message and stop when pkgStatus is not right.
44      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
45    
46    checkpoint64m (2013/08/13)
47    o model/inc:
48      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
49        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
50    o pkg/kpp & aim_v23:
51      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
52    o pkg/seaice:
53      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
54        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
55      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
56    o eesupp/src:
57      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
58        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
59    o switch to TAF version-2:
60      - add flow directives to "freeze" naming convention for ad-routines that
61        are used in I/O routines of adjoint state and associated common blocks
62        that are used in adcommon.h (backward compatible with version-1)
63      - update all ad-optfiles (in tools/adjoint_options + few local to some
64        verification exp) to switch to latest TAF version (currently 2.5.5);
65        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
66        out except for diva).
67      - the major change with TAF version-2 is that both the differentiated
68        routines and the forward routines (new) are returned as part of the TAF
69        output source code. Update genmake2 accordingly.
70      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
71        with version-2 when compared to TLM or FWD gradient); other experiments
72        output show minor changes (machine truncation level); update the few AD &
73        TLM output with 12 matching digits only (some prior to version-2 switch).
74    
75    checkpoint64l (2013/08/05)
76    o model/src:
77      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
78      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
79        when using TAF but only if using OpenAD.
80    o pkg/mom_common+fluxform+vecinv:
81      - always set horiz. viscosity arrays to background value before calling
82        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
83        only when using variable horiz. viscosity (useVariableVisc=T);
84      - simplify mom_vecinv.F (only 1 block for momViscosity).
85    o pkg/mom_common: variable horiz. viscosity in NH code
86      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
87        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
88      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
89        useBiharmonicVisc & useVariableVisc.
90      - fix old bug (already in 1rst implementation of variable horizontal viscosity
91        in calc_gw.F, version 1.27, 2006/06/20):
92        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
93        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
94      - change background horiz viscosity in vertical momentum (gW) to always be
95        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
96        any type of variable viscosity, e.g., viscAh/4Grid)
97      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
98        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
99        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
100        default viscAh,viscA4 is zero).
101    o model/src:
102      - extend length of drC & recip_drC from Nr to Nr+1.
103    o Divided Adjoint (DIVA) with MPI:
104      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
105      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
106        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
107    
108    checkpoint64k (2013/07/23)
109    o tools/OAD_support:
110      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
111        and remove it from genmake2.
112    o tools/build_options:
113      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
114        MPI_HEADER_FILES list (let genmake2 find the missing headers)
115    o verification/halfpipe_streamice:
116      - change to driving stress formulation; update both Fwd & AD output.
117    o tools/genmake2 and Divided Adjoint with MPI:
118      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
119      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
120      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
121        Makefile, which is set by genmake2, and check which mpi-headers are needed.
122        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
123      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
124    o testreport:
125      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
126        perform additional runs (number of additional runs is "add_DIVA_runs" taken
127        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
128    o verification/lab_sea (AD test):
129      - change to test Divided Adjoint Run in this set-up (both standard AD test
130        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
131    o pkg atm_ & ocn_compon_interf:
132      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
133        staggerTimeStep implementation) and disable (retired) corresponding
134        parameter.
135    o pkg/offline:
136      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
137      - add S/R OFFLINE_CHECK to print offline parameter summary
138        and stop if loading a file that is not used;
139      - enable to calculate GMRedi tensor, KPP mixing and convective index
140        when the corresponding file(s) is/are not specified (but pkg is used).
141      - comment out resetting of monitorFreq (to endTime) since it still useful
142        for monitoring CFL numbers and checking offline fields.
143    o OpenAD:
144      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
145        smaller standard output) and generate new (smaller) output (on baudelaire
146        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
147    o model/src:
148      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
149        (where external_forcing_adjust was called) and change list of arguments;
150      - merge external_forcing_adjust.F into external_forcing_surf.F
151      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
152        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
153        previously in file "balance_relax.F", now removed); remove corresponding
154        arrays in FFIELDS.h.
155      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
156        a hack for getting back surfaceForcingS (loaded from file) when using
157        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
158      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
159        (was getting only 11 digits for AD-grad, due to different truncation
160         error in AD code).
161    
162    checkpoint64j (2013/07/04)
163    o pkg/offline:
164      - to enable the use of other features with pkg offline (e.g., obcs),
165        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
166      - comment out "allowFreezing" (now active) in 2 offline testing exp.
167    o pkg/exf ALLOW_RUNOFTEMP
168      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
169      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
170      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
171    o pkg/atm_phys:
172      - allows to add some damping on uVel,vVel (strength only function of k).
173    o verification, ad-tests:
174      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
175        global_ocean_ebm and offline_exf_seaice.thsice.
176    o verification/halfpipe_streamice:
177      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
178        flux input boundary conditions to be ignored; a fix for this bug changed
179        verification results for forward test.
180      - add adjoint test.
181    o pkg/ptracers:
182      - allow to restart without SOM pickup (resetting SOM to zero).
183    o pkg/gmredi:
184      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
185      - It uses mixing length theory and suppression by steering level effects to
186        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
187        to JPO, for more details).
188      - It also uses the diffusivity to calculate an eddy induced streamfunction
189        based on a PV closure (rather than a buoyancy closure as in GM).
190      - New files added to pkg/gmredi:
191        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
192          induced overturning streamfunction (called from gmredi_calc_tensor)
193        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
194          for use in gmredi_k3d
195        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
196          the eddy diffusivity
197    
198    checkpoint64i (2013/06/18)
199    o pkg/cheapaml:
200      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
201        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
202        with pkg/cheapaml.
203    o utils/python: add subpackage for cubed sphere function, first example is
204        simple cs.pcol to plot 2D fields on a map
205    o pkg/streamice:
206      - This is a new package in MITgcm, which solves dynamic equations for ice
207         sheets and ice streams
208      - At the moment it is independent of atmosphere/ocean dynamics, or any
209        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
210        ed that this will change)
211      - There is a new verification exercise that tests it, halfpipe_streamice,
212        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
213        rectangular embayment
214      - halfpipe_streamice is forward-only for now, will have TAF test soon
215      - for questions, email dgoldber@mit.edu
216    o pkg/thsice:
217      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
218        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
219      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
220         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
221      - allow precip from pkg/cheapaml to make snow over seaice.
222    o pkg/cfc:
223      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
224      - remove atmos CFC 2-D arrays from common bloc (now local variables)
225      - change some hard-coded constant to run time parameter for reading and
226        and interpolating atmospheric CFC ; keep same default as previously.
227      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
228      - put arguments in standard order: myTime, myIter, myThid
229      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
230        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
231      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
232      - new routine to print summary of CFC params and check for consistency.
233    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
234      similar to thsice_advdiff.
235      Note that for the B-grid case the routine parameters uc/vc are overwritten.
236    o pkg/cfc:
237      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
238        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
239      - fix interpolation of atmphspheric CFC between Sorthern and Northern
240        hemisphere value.
241    o pkg/seaice:
242      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
243    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
244                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
245      - requires an additional time level that is stored in the pickup
246      - you can start with AB2 from a pickup without this time level with
247        pickupStrictlyMatch = .false.
248    
249    checkpoint64h (2013/05/26)
250    o pkg/cheapaml:
251      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
252        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
253      - consistent treatment of uWind,vWind location: assume everywhere in
254        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
255        (Note: was already the case for Tair,Qair advection);
256        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
257      - compute diabatic forcing only in the interior (excluding overlap regions)
258      - fill in array "Qsw" (for short-wave heating);
259      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
260        before any update (consistent with MITgcm state var diagnostics);
261      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
262        non periodic ; + adjusted for uWind,vWind (C-grid).
263    o pkg/seaice:
264      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
265        add explicitly pkg/exf in experiments that currently use pkg/seaice.
266      - allows to compile pkg/seaice without pkg/exf.
267    o tools/OAD_support:
268      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
269        of array "ourStepOf" in function rvNextAction (revolve.F90).
270    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
271      - change pkg name (to be used with other atmospheric physics pkg)
272        but by-pass CVS when making the new pkg so that we keep the CVS history.
273    o pkg/offline:
274      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
275        (previously called from pkg/dic_surfforcing_init.F)
276    o model/src:
277      - re-order sequence of calls within packages_init_variables.F, using
278        standard order, except for:
279         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
280         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
281    o new pkg: atm_phys
282      - add entry point and source code (previously in contrib
283          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
284        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
285      - re-order sequence of calls within packages_readparms.F,
286         packages_init_fixed.F and packages_write_pickup.F
287        (but skip packages_init_variables.F because of TAF issues).
288      - update contrib/*/atm_gray/ experiment.
289    o pkg/seaice (ITD code):
290      - simplify and fix the writing of pickup-files for ITD case
291    o pkg/seaice (ITD code):
292      - introduce floe size dependent lateral melt for ITD case;
293      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
294      - update seaice_itd experiment main output.
295    o pkg/thsice:
296      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
297        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
298        changed accordingly pkg/atm2d.
