4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ctrl/ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
8    o pkg/ecco
9     - enable adjoint of Stevens OB
10    o pkg/ctrl/ecco/grdchk:
11      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
12        Fortunately, we do not have any tests for the numerous cpp-flagged
13        option of "obcs as control parameters" so we will never know
14        if this is an improvement (but at least now things compile).
15      - remove an obsolete initialization from ecco_cost_init_barfiles.F
16      - fix some problems within never used ifdefs to make the code compile
17    o pkg/obcs:
18     - Refine Interior mask definition to work with more complex OB (e.g.
19       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
20       read in Interior mask from file. Check if Interior mask is consistent
21       with OB list of indices.
22    o pkg/seaice
23     - beginning code for a seaice tracer package,
24       but currently only used for seaice age: SEAICE_AGE
25       SEAICE_num = 4
26       iTracer = 1: area-weighted ice age
27               = 2: volume-weighted ice age
28               = 3, 4: template for one-year vs. multi-year ice
29       data.seaice has new namelist SEAICE_PARM03 for arrays related to
30       SEAICE_num
31    
32    checkpoint62t (2011/03/05)
33    o pkg/obcs:
34     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
35       then normal component. This ensures that the normal component is set
36       correctly even when it conficts with tangential setting from an other OB.
37       Affects results of test-experiment seaice_obcs: update the output.txt
38    o pkg/obcs:
39     - add code to monitor statistics of dynamical fields at OB.
40     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
41       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
42       - change default: balance the Net inflow through all OB (instead of balancing
43         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
44     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
45       to match Nortern OB inflow (OBCS_balanceFacN=0).
46    o pkg/seaice:
47     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
48    o pkg/seaice (seaice_growth v 1.113):
49     - reverting seaice_growth to v 1.111 in order to have code with exact bit
50       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
51       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
52       runtime flag SEAICEareaFormula is kept but is inactive
53    o model/src:
54     - add new param to scale curvilinear grid distance and area when using
55       a different sphere radius from the grid-files.
56     - test/check multi-threads EXCH applied to local variable (cg2d_x)
57    o adjoint:
58     - enable adjoint of Stevens OB
59     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
60       (a bit delicate because of potentially modified adj. common block structure;
61       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
62    
63    checkpoint62s (2011/02/15)
64    o pkg/seaice (seaice_growth v 1.112):
65     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
66       computing the ice cover tendency from effective thickness tendencies. Include
67       Ian Fenty's formula.
68     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
69       SEAICEareaFormula.
70     - simplify notations for the various d_HEFF/d_AREA terms.
71    o pkg/gmredi:
72     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
73       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
74       add a verification test-run (front_relax.bvp) to test GM_useBVP.
75    o pkg/seaice (seaice_growth v 1.111):
76     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
77     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
78       also melt ice.
79    o pkg/seaice:
80     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
81     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
82    o pkg/cheapaml:
83     - from Nico Wienders: New version of this package.
84    o pkg/flt:
85     - add CPP options to prevent floats to re-enter the opposite side of
86       a periodic domain (default: keep periodicity)
87    o pkg/gmredi:
88     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
89       (needed for multi-dim advection).
90     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
91    o model/src:
92     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
93    o tutorial_tracer_adjsens
94     - extend to NLFS and replace maskC by hFacC
95       (change reference output accordingly)
96    
97    checkpoint62r (2011/01/24)
98    o testreport:
99     - add option -deloutp (-do) to remove output file after successful run
100     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
101       extract exact list of procs from this file ; adjust COMMAND by
102       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
103    o pkg/ecco: replace old ineffective way of penalizing deviations from
104      first guess (of obcs) with code by Matt Mazloff
105    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
106      exf/cal
107      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
108        and handle case of obcs?period == 0
109        Not affected by these changes: There is still an inconsistency in
110        the computation of start/endrec for the obcs variables for ALLOW_CAL
111        defined (see comment by Menemenlis, 7-Mar-2003)
112      - make S/R ctrl_get_gen_rec return something meaningful even if
113        ALLOW_CAL is not defined
114      - ctrl_getobcs?: simplify code so that it does not need to use
115                       S/R exf_swapfields
116    o testreport:
117       allow to test MPI with different number of processors for each experiment:
118       create file "SIZE.h.mpi" in each build dir.
119       Note: update of "-command" argument not yet implemented.
120    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
121      alleviate the need for additional 3D tapes when using
122      the non-inear free surface in the adjoint. This is done
123      by adding an 'update' of hfacc etc. to their current
124      value at the beginning of forward_step.F.
125    o pkg/seaice
126      seaice_lsr: move stress-divergence computations out of outer pseudo-
127      timestepping loop
128    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
129      up, so that the calls of the ctrl_* subroutines are really at the end
130      of the routine.
131    o pkg/gmredi:
132      allow to specify a 2-D horizontal map and a 1-D vertical profil
133      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
134    o pkg/seaice:
135      move lsr iterations from seaice_dynsolver to seaice_lsr.
136    o pkg/seaice:
137      reduce memory footprint of seaice mutldim advection tapes,
138      by using a 2D tape independent of the generic_advdiff ones,
139      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
140    
141    checkpoint62q (2010/12/29)
142    o model/src:
143      - check horizontal grid-spacing for unset or zero/negative values.
144      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
145    o pkg/flt:
146      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
147      - precision of input and output files set according to readBinaryPrec
148        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
149      - initial float position from tiled file was not converted to index space
150        (looks like a bug): fixed to make it similar to initial pos. global file.
151    o global_ocean.cs32x15:
152       change SIZE.h of AD set-up to get same tiling as with MPI.
153       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
154    o model/src:
155       add flag to control printing of domain fields (bathymetry, hFac ...) in
156       ini_mask_etc (call to plot_fieds_xy*).
157    o pkg/thsice:
158       if useEXF, some forcing fields are not valid in overlap: fixed by computing
159       over the interior only + apply EXCH at the end (like with SEAICE advection).
160    o pkg/mdsio:
161      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
162        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
163      - change barrier call for safe multi-threads access to 3-D shared buffer.
164      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
165      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
166        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
167    o pkg/flt:
168      - add fourth-order Runge-Kutta integration
169      - add basic exch2 support (only 1 facet supported so far!)
170    o pkg/mdsio+rw:
171      new S/R to read local (or tile independent) vector (read counterpart of
172       mds_writevec_loc, and front-end write_glvec_rl/rs).
173    o global_ocean.cs32x15: additional input_ad.seaice experiment
174        that uses pkg/seaice rather than pkg/thsice.
175        (using multidim advection for seaice)
176    o towards more F95 syntax for array specification in namelist:
177      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
178        of all verification experiments.
179           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
180          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
181      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
182    o global_ocean.cs32x15: additional input.seaice experiment
183        that uses pkg/seaice rather than pkg/thsice.
184    
185    checkpoint62p (2010/12/17)
186    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
187        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
188    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
189        allow for use of multim. advection in seaice adjoint.
190    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
191      - first attempt to close budgets by taking into account the freshwater
192        flux implied by the sublimation of snow and ice. So far only the
193        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
194        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
195    o eesupp/src:
196      new S/R with new option (NML_EXTENDED_F77) to change array specification
197      from F95 standard to commonly accepted extended F77 form.
198      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
199      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
200      for less tolerant f77 compiler (e.g., pgf77, g77).
201    o globalFiles:
202      commented out in parameter file "data" since it's not safe with MPI
203      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
204      in this case); no longer commented out in restart test (tst_2+2).
205    o add adTapeDir to specify a special directory where adjoint tapes are
206      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
207      and cannot be used together with mdsioLocalDir.
208    o nesting pkgs:
209      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
210      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
211      - add parameter files + utils dir + output from short run on beagle.
212    o pkg/seaice:
213        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
214    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
215      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
216    
217    checkpoint62o (2010/11/25)
218    o pkg/exf:
219      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
220    o pkg/seaice:
221      - seaice_ocean_stress: split a loop for better vectorization of the
222        adjoint code
223      - seaice_growth.F: fix bug in conservation of freshwater connected to
224        capping of heff, put contribution into d_HEFFbyNEG
225      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
226        by something more sensible (parameters that are what their name implies)
227      - change some defaults, so that by default exf-parameters are used for
228        things like rhoAir, cpAir,latent/sensible heat parameters, in order
229        to reproduce the old results, many data.seaice now contain funny values
230        for cpAir and latent heat of sublimation
231    o packages_readparms.F: move exf_readparms up in line so that
232        exf-parameters are visible for other packages (e.g. seaice)
233    o debugMode & debugLevel=2:
234      - differentiate between debugMode & debugLevel=2:
235        debugMode: controls printing of debug messages (sequence of S/R calls).
236        debugLevel: controls printing of algorithm intermediate results and stats.
237      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
238        => allows to print debug-stats without all sequence of call messages.
239      - switch control of debug print from debugLevel to debugMode in many S/R.
240    o pkg/obcs (obcs-sponge):
241        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
242        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
243    o pkg/generic_advdiff:
244      - record overlap minimum size for each advection scheme;
245      - refine criteria on overlap minimum size;
246      - check and stop (in gad_check) if overlap size is too small.
247    o pkg/obcs:
248      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
249        once, in ptracers_implicit.F)
250      - with seaice: remove test on empty file name in obcs_apply_seaice (always
251        apply OB values when tile has OB)
252    o model/src, coriolis setting:
253      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
254        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
255        files (selectCoriMap=3) with any grid.
256      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
257    o pkg/seaice/seaice_growth.F:
258        a few cosmetic changes that reduce the number of lines of code
259    o pkg/obcs: add boundary conditions following Stevens (1990)
260      - the code follows old MOM/NAOSIM code
261      - so far it is only implemented for the eastern and western boundaries
262        and NOT for pTracers
263    o pkg/rbcs:
264      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
265        beginning of the first rbcs forcing period.
266      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
267        offline package, i.e., one file per time, labeled by iteration number;
268        deltaTrbcs sets the timestep with which the data was generated;
269        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
270      - rbcsForcingCycle=0 makes forcing non-cyclic.
271      - make arithmetic safe for negative times and odd forcing periods.
272    
273    checkpoint62n (2010/11/09)
274    o pkg/seaice:
275        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
276    o pkg/obcs:
277       New S/R to copy tracer value from the OB location to narrow band region
278        (width = same as overlap) beyond the OB: preserve OB value (needed for
279        high-order scheme) which were overwritten by EXCH call if in overlap
280        region. Applied to theta, salt, ptracer and advected seaice variables.
281       With seaice: use maskInC in similar way as in gad_advection.F,
282        in seaice_advection.F and advect.F.
283       Update output of experiment seaice_obcs and change exp4 to test OBCS with
284        4th order Adv.Scheme. for pasive salt and ptracer.
285    o tools/genmake2:
286      - when looking for an optfile (not specified), only search for Fortran compiler
287        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
288      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
289        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
290      - set default for CPP to "cpp -traditional -P" (was the case without specifying
291        an optfile, but otherwise default was just "cpp".
292      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
293      - when "CC" is not set in the optfile, look for possible C compiler
294        (instead of just setting CC=cc)
295      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
296        => add a ".F" to ".o" rule for source files with no "#include" (such as
297           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
298      - move gfortran before g77 in list of possible Fortran compiler (consistent
299        with reference compiler switch from g77 to gfortran)
300    o pkg/seaice:
301      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
302        seaice_check that stops the model, when the CPP flag is used.
303      o seaice_growth.F: make capping of ice volume conserving by returning the
304        capped ice as freshwater to EmPmR. This does not change the verification
305        experiments but will change runs where the capping is acutally active
306    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
307      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
308         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
309         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
310    o tools/genmake2:
311      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
312      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
313      - clean previous genmake log files before anything else.
314      - change Makefile to remove testreport log files (*.tr_log) and genmake log
315        files only with "CLEAN" target (instead of "Clean");
316    o pkg/generic_advdiff:
317      Change OBCS in multiDim advection (gad_advection.F):
318       Use maskInC to prevent intermediate update of tracer-field in OB regions,
319       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
320       which were applying future time-step OB values.
321      This way, all explicit calculations use current-time-step OB values
322       (simpler and more consistent).
323      Affects results when set-up uses time-varying OBC and multi-dim advection;
324       update output of experiment seaice_obcs.
325    o pkg/seaice:
326      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
327       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
328         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
329      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
330       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
331       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
332  o pkg aim (2010/10/26):  o pkg aim (2010/10/26):
333    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
334      formulation with obliquity, eccentricity, ... as run-time parameters,      formulation with obliquity, eccentricity, ... as run-time parameters,
335    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
336      upward shortwave radition at the surface (all-sky and clear-sky).      upward shortwave radition at the surface (all-sky and clear-sky).
   
337  o pkg/obcs:  o pkg/obcs:
338    - writing sections with globalFiles=T does not work: switch to tiled-files    - writing sections with globalFiles=T does not work: switch to tiled-files
339      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
