4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8     - add new param to scale curvilinear grid distance and area when using
9       a different sphere radius from the grid-files.
10     - test/check multi-threads EXCH applied to local variable (cg2d_x)
11    
12    checkpoint62s (2011/02/15)
13    o pkg/seaice:
14     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
15       computing the ice cover tendency from effective thickness tendencies. Include
16       Ian Fenty's formula.
17     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
18       SEAICEareaFormula.
19     - simplify notations for the various d_HEFF/d_AREA terms.
20    o pkg/gmredi:
21     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
22       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
23       add a verification test-run (front_relax.bvp) to test GM_useBVP.
24    o pkg/seaice:
25     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
26     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
27       also melt ice.
28    o pkg/seaice:
29     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
30     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
31    o pkg/cheapaml:
32     - from Nico Wienders: New version of this package.
33    o pkg/flt:
34     - add CPP options to prevent floats to re-enter the opposite side of
35       a periodic domain (default: keep periodicity)
36    o pkg/gmredi:
37     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
38       (needed for multi-dim advection).
39     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
40    o model/src:
41     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
42    o tutorial_tracer_adjsens
43     - extend to NLFS and replace maskC by hFacC
44       (change reference output accordingly)
45    
46    checkpoint62r (2011/01/24)
47    o testreport:
48     - add option -deloutp (-do) to remove output file after successful run
49     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
50       extract exact list of procs from this file ; adjust COMMAND by
51       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
52    o pkg/ecco: replace old ineffective way of penalizing deviations from
53      first guess (of obcs) with code by Matt Mazloff
54    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
55      exf/cal
56      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
57        and handle case of obcs?period == 0
58        Not affected by these changes: There is still an inconsistency in
59        the computation of start/endrec for the obcs variables for ALLOW_CAL
60        defined (see comment by Menemenlis, 7-Mar-2003)
61      - make S/R ctrl_get_gen_rec return something meaningful even if
62        ALLOW_CAL is not defined
63      - ctrl_getobcs?: simplify code so that it does not need to use
64                       S/R exf_swapfields
65    o testreport:
66       allow to test MPI with different number of processors for each experiment:
67       create file "SIZE.h.mpi" in each build dir.
68       Note: update of "-command" argument not yet implemented.
69    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
70      alleviate the need for additional 3D tapes when using
71      the non-inear free surface in the adjoint. This is done
72      by adding an 'update' of hfacc etc. to their current
73      value at the beginning of forward_step.F.
74    o pkg/seaice
75      seaice_lsr: move stress-divergence computations out of outer pseudo-
76      timestepping loop
77    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
78      up, so that the calls of the ctrl_* subroutines are really at the end
79      of the routine.
80    o pkg/gmredi:
81      allow to specify a 2-D horizontal map and a 1-D vertical profil
82      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
83    o pkg/seaice:
84      move lsr iterations from seaice_dynsolver to seaice_lsr.
85    o pkg/seaice:
86      reduce memory footprint of seaice mutldim advection tapes,
87      by using a 2D tape independent of the generic_advdiff ones,
88      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
89    
90    checkpoint62q (2010/12/29)
91    o model/src:
92      - check horizontal grid-spacing for unset or zero/negative values.
93      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
94    o pkg/flt:
95      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
96      - precision of input and output files set according to readBinaryPrec
97        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
98      - initial float position from tiled file was not converted to index space
99        (looks like a bug): fixed to make it similar to initial pos. global file.
100    o global_ocean.cs32x15:
101       change SIZE.h of AD set-up to get same tiling as with MPI.
102       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
103    o model/src:
104       add flag to control printing of domain fields (bathymetry, hFac ...) in
105       ini_mask_etc (call to plot_fieds_xy*).
106    o pkg/thsice:
107       if useEXF, some forcing fields are not valid in overlap: fixed by computing
108       over the interior only + apply EXCH at the end (like with SEAICE advection).
109    o pkg/mdsio:
110      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
111        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
112      - change barrier call for safe multi-threads access to 3-D shared buffer.
113      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
114      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
115        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
116    o pkg/flt:
117      - add fourth-order Runge-Kutta integration
118      - add basic exch2 support (only 1 facet supported so far!)
119    o pkg/mdsio+rw:
120      new S/R to read local (or tile independent) vector (read counterpart of
121       mds_writevec_loc, and front-end write_glvec_rl/rs).
122    o global_ocean.cs32x15: additional input_ad.seaice experiment
123        that uses pkg/seaice rather than pkg/thsice.
124        (using multidim advection for seaice)
125    o towards more F95 syntax for array specification in namelist:
126      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
127        of all verification experiments.
128           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
129          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
130      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
131    o global_ocean.cs32x15: additional input.seaice experiment
132        that uses pkg/seaice rather than pkg/thsice.
133    
134    checkpoint62p (2010/12/17)
135    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
136        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
137    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
138        allow for use of multim. advection in seaice adjoint.
139    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
140      - first attempt to close budgets by taking into account the freshwater
141        flux implied by the sublimation of snow and ice. So far only the
142        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
143        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
144    o eesupp/src:
145      new S/R with new option (NML_EXTENDED_F77) to change array specification
146      from F95 standard to commonly accepted extended F77 form.
147      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
148      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
149      for less tolerant f77 compiler (e.g., pgf77, g77).
150    o globalFiles:
151      commented out in parameter file "data" since it's not safe with MPI
152      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
153      in this case); no longer commented out in restart test (tst_2+2).
154    o add adTapeDir to specify a special directory where adjoint tapes are
155      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
156      and cannot be used together with mdsioLocalDir.
157    o nesting pkgs:
158      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
159      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
160      - add parameter files + utils dir + output from short run on beagle.
161    o pkg/seaice:
162        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
163    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
164      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
165    
166    checkpoint62o (2010/11/25)
167    o pkg/exf:
168      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
169    o pkg/seaice:
170      - seaice_ocean_stress: split a loop for better vectorization of the
171        adjoint code
172      - seaice_growth.F: fix bug in conservation of freshwater connected to
173        capping of heff, put contribution into d_HEFFbyNEG
174      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
175        by something more sensible (parameters that are what their name implies)
176      - change some defaults, so that by default exf-parameters are used for
177        things like rhoAir, cpAir,latent/sensible heat parameters, in order
178        to reproduce the old results, many data.seaice now contain funny values
179        for cpAir and latent heat of sublimation
180    o packages_readparms.F: move exf_readparms up in line so that
181        exf-parameters are visible for other packages (e.g. seaice)
182    o debugMode & debugLevel=2:
183      - differentiate between debugMode & debugLevel=2:
184        debugMode: controls printing of debug messages (sequence of S/R calls).
185        debugLevel: controls printing of algorithm intermediate results and stats.
186      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
187        => allows to print debug-stats without all sequence of call messages.
188      - switch control of debug print from debugLevel to debugMode in many S/R.
189    o pkg/obcs (obcs-sponge):
190        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
191        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
192    o pkg/generic_advdiff:
193      - record overlap minimum size for each advection scheme;
194      - refine criteria on overlap minimum size;
195      - check and stop (in gad_check) if overlap size is too small.
196    o pkg/obcs:
197      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
198        once, in ptracers_implicit.F)
199      - with seaice: remove test on empty file name in obcs_apply_seaice (always
200        apply OB values when tile has OB)
201    o model/src, coriolis setting:
202      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
203        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
204        files (selectCoriMap=3) with any grid.
205      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
206    o pkg/seaice/seaice_growth.F:
207        a few cosmetic changes that reduce the number of lines of code
208    o pkg/obcs: add boundary conditions following Stevens (1990)
209      - the code follows old MOM/NAOSIM code
210      - so far it is only implemented for the eastern and western boundaries
211        and NOT for pTracers
212    o pkg/rbcs:
213      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
214        beginning of the first rbcs forcing period.
215      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
216        offline package, i.e., one file per time, labeled by iteration number;
217        deltaTrbcs sets the timestep with which the data was generated;
218        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
219      - rbcsForcingCycle=0 makes forcing non-cyclic.
220      - make arithmetic safe for negative times and odd forcing periods.
221    
222    checkpoint62n (2010/11/09)
223    o pkg/seaice:
224        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
225    o pkg/obcs:
226       New S/R to copy tracer value from the OB location to narrow band region
227        (width = same as overlap) beyond the OB: preserve OB value (needed for
228        high-order scheme) which were overwritten by EXCH call if in overlap
229        region. Applied to theta, salt, ptracer and advected seaice variables.
230       With seaice: use maskInC in similar way as in gad_advection.F,
231        in seaice_advection.F and advect.F.
232       Update output of experiment seaice_obcs and change exp4 to test OBCS with
233        4th order Adv.Scheme. for pasive salt and ptracer.
234    o tools/genmake2:
235      - when looking for an optfile (not specified), only search for Fortran compiler
236        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
237      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
238        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
239      - set default for CPP to "cpp -traditional -P" (was the case without specifying
240        an optfile, but otherwise default was just "cpp".
241      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
242      - when "CC" is not set in the optfile, look for possible C compiler
243        (instead of just setting CC=cc)
244      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
245        => add a ".F" to ".o" rule for source files with no "#include" (such as
246           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
247      - move gfortran before g77 in list of possible Fortran compiler (consistent
248        with reference compiler switch from g77 to gfortran)
249    o pkg/seaice:
250      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
251        seaice_check that stops the model, when the CPP flag is used.
252      o seaice_growth.F: make capping of ice volume conserving by returning the
253        capped ice as freshwater to EmPmR. This does not change the verification
254        experiments but will change runs where the capping is acutally active
255    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
256      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
257         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
258         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
259    o tools/genmake2:
260      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
261      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
262      - clean previous genmake log files before anything else.
263      - change Makefile to remove testreport log files (*.tr_log) and genmake log
264        files only with "CLEAN" target (instead of "Clean");
265    o pkg/generic_advdiff:
266      Change OBCS in multiDim advection (gad_advection.F):
267       Use maskInC to prevent intermediate update of tracer-field in OB regions,
268       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
269       which were applying future time-step OB values.
270      This way, all explicit calculations use current-time-step OB values
271       (simpler and more consistent).
272      Affects results when set-up uses time-varying OBC and multi-dim advection;
273       update output of experiment seaice_obcs.
274    o pkg/seaice:
275      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
276       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
277         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
278      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
279       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
280       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
281    o pkg aim (2010/10/26):
282      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
283        formulation with obliquity, eccentricity, ... as run-time parameters,
284      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
285        upward shortwave radition at the surface (all-sky and clear-sky).
286    o pkg/obcs:
287      - writing sections with globalFiles=T does not work: switch to tiled-files
288        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
289      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
290      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
291    
292    checkpoint62m (2010/10/21)
293    o pkg/seaice: vectorize seaice_solve4temp.F
294      - move iterations loops outside of i/j-loops
295      - requires 2D arrays for TB and effConduct
296      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
297        modified in this routine
298      - a little bit of clean up, adjusting indentation, etc.
299      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
300        performance and '**TWO' by '**2' (because TWO is a float),
301        replaced ONE, ZERO
302  o eesupp/src:  o eesupp/src:
303     fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube     fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
