4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/flt:
8      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
9      - precision of input and output files set according to readBinaryPrec
10        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
11      - initial float position from tiled file was not converted to index space
12        (looks like a bug): fixed to make it similar to initial pos. global file.
13    o global_ocean.cs32x15:
14       change SIZE.h of AD set-up to get same tiling as with MPI.
15       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
16    o model/src:
17       add flag to control printing of domain fields (bathymetry, hFac ...) in
18       ini_mask_etc (call to plot_fieds_xy*).
19    o pkg/thsice:
20       if useEXF, some forcing fields are not valid in overlap: fixed by computing
21       over the interior only + apply EXCH at the end (like with SEAICE advection).
22    o pkg/mdsio:
23      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
24        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
25      - change barrier call for safe multi-threads access to 3-D shared buffer.
26      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
27      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
28        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
29    o pkg/flt:
30      - add fourth-order Runge-Kutta integration
31      - add basic exch2 support (only 1 facet supported so far!)
32    o pkg/mdsio+rw:
33      new S/R to read local (or tile independent) vector (read counterpart of
34       mds_writevec_loc, and front-end write_glvec_rl/rs).
35    o global_ocean.cs32x15: additional input_ad.seaice experiment
36        that uses pkg/seaice rather than pkg/thsice.
37        (using multidim advection for seaice)
38    o towards more F95 syntax for array specification in namelist:
39      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
40        of all verification experiments.
41           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
42          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
43      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
44    o global_ocean.cs32x15: additional input.seaice experiment
45        that uses pkg/seaice rather than pkg/thsice.
46    
47    checkpoint62p (2010/12/17)
48    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
49        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
50    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
51        allow for use of multim. advection in seaice adjoint.
52    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
53      - first attempt to close budgets by taking into account the freshwater
54        flux implied by the sublimation of snow and ice. So far only the
55        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
56        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
57    o eesupp/src:
58      new S/R with new option (NML_EXTENDED_F77) to change array specification
59      from F95 standard to commonly accepted extended F77 form.
60      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
61      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
62      for less tolerant f77 compiler (e.g., pgf77, g77).
63    o globalFiles:
64      commented out in parameter file "data" since it's not safe with MPI
65      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
66      in this case); no longer commented out in restart test (tst_2+2).
67    o add adTapeDir to specify a special directory where adjoint tapes are
68      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
69      and cannot be used together with mdsioLocalDir.
70    o nesting pkgs:
71      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
72      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
73      - add parameter files + utils dir + output from short run on beagle.
74    o pkg/seaice:
75        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
76    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
77      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
78    
79    checkpoint62o (2010/11/25)
80    o pkg/exf:
81      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
82    o pkg/seaice:
83      - seaice_ocean_stress: split a loop for better vectorization of the
84        adjoint code
85      - seaice_growth.F: fix bug in conservation of freshwater connected to
86        capping of heff, put contribution into d_HEFFbyNEG
87      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
88        by something more sensible (parameters that are what their name implies)
89      - change some defaults, so that by default exf-parameters are used for
90        things like rhoAir, cpAir,latent/sensible heat parameters, in order
91        to reproduce the old results, many data.seaice now contain funny values
92        for cpAir and latent heat of sublimation
93    o packages_readparms.F: move exf_readparms up in line so that
94        exf-parameters are visible for other packages (e.g. seaice)
95    o debugMode & debugLevel=2:
96      - differentiate between debugMode & debugLevel=2:
97        debugMode: controls printing of debug messages (sequence of S/R calls).
98        debugLevel: controls printing of algorithm intermediate results and stats.
99      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
100        => allows to print debug-stats without all sequence of call messages.
101      - switch control of debug print from debugLevel to debugMode in many S/R.
102    o pkg/obcs (obcs-sponge):
103        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
104        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
105    o pkg/generic_advdiff:
106      - record overlap minimum size for each advection scheme;
107      - refine criteria on overlap minimum size;
108      - check and stop (in gad_check) if overlap size is too small.
109    o pkg/obcs:
110      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
111        once, in ptracers_implicit.F)
112      - with seaice: remove test on empty file name in obcs_apply_seaice (always
113        apply OB values when tile has OB)
114    o model/src, coriolis setting:
115      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
116        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
117        files (selectCoriMap=3) with any grid.
118      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
119    o pkg/seaice/seaice_growth.F:
120        a few cosmetic changes that reduce the number of lines of code
121    o pkg/obcs: add boundary conditions following Stevens (1990)
122      - the code follows old MOM/NAOSIM code
123      - so far it is only implemented for the eastern and western boundaries
124        and NOT for pTracers
125    o pkg/rbcs:
126      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
127        beginning of the first rbcs forcing period.
128      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
129        offline package, i.e., one file per time, labeled by iteration number;
130        deltaTrbcs sets the timestep with which the data was generated;
131        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
132      - rbcsForcingCycle=0 makes forcing non-cyclic.
133      - make arithmetic safe for negative times and odd forcing periods.
134    
135    checkpoint62n (2010/11/09)
136    o pkg/seaice:
137        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
138    o pkg/obcs:
139       New S/R to copy tracer value from the OB location to narrow band region
140        (width = same as overlap) beyond the OB: preserve OB value (needed for
141        high-order scheme) which were overwritten by EXCH call if in overlap
142        region. Applied to theta, salt, ptracer and advected seaice variables.
143       With seaice: use maskInC in similar way as in gad_advection.F,
144        in seaice_advection.F and advect.F.
145       Update output of experiment seaice_obcs and change exp4 to test OBCS with
146        4th order Adv.Scheme. for pasive salt and ptracer.
147    o tools/genmake2:
148      - when looking for an optfile (not specified), only search for Fortran compiler
149        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
150      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
151        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
152      - set default for CPP to "cpp -traditional -P" (was the case without specifying
153        an optfile, but otherwise default was just "cpp".
154      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
155      - when "CC" is not set in the optfile, look for possible C compiler
156        (instead of just setting CC=cc)
157      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
158        => add a ".F" to ".o" rule for source files with no "#include" (such as
159           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
160      - move gfortran before g77 in list of possible Fortran compiler (consistent
161        with reference compiler switch from g77 to gfortran)
162    o pkg/seaice:
163      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
164        seaice_check that stops the model, when the CPP flag is used.
165      o seaice_growth.F: make capping of ice volume conserving by returning the
166        capped ice as freshwater to EmPmR. This does not change the verification
167        experiments but will change runs where the capping is acutally active
168    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
169      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
170         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
171         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
172    o tools/genmake2:
173      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
174      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
175      - clean previous genmake log files before anything else.
176      - change Makefile to remove testreport log files (*.tr_log) and genmake log
177        files only with "CLEAN" target (instead of "Clean");
178    o pkg/generic_advdiff:
179      Change OBCS in multiDim advection (gad_advection.F):
180       Use maskInC to prevent intermediate update of tracer-field in OB regions,
181       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
182       which were applying future time-step OB values.
183      This way, all explicit calculations use current-time-step OB values
184       (simpler and more consistent).
185      Affects results when set-up uses time-varying OBC and multi-dim advection;
186       update output of experiment seaice_obcs.
187    o pkg/seaice:
188      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
189       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
190         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
191      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
192       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
193       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
194    o pkg aim (2010/10/26):
195      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
196        formulation with obliquity, eccentricity, ... as run-time parameters,
197      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
198        upward shortwave radition at the surface (all-sky and clear-sky).
199    o pkg/obcs:
200      - writing sections with globalFiles=T does not work: switch to tiled-files
201        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
202      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
203      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
204    
205    checkpoint62m (2010/10/21)
206    o pkg/seaice: vectorize seaice_solve4temp.F
207      - move iterations loops outside of i/j-loops
208      - requires 2D arrays for TB and effConduct
209      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
210        modified in this routine
211      - a little bit of clean up, adjusting indentation, etc.
212      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
213        performance and '**TWO' by '**2' (because TWO is a float),
214        replaced ONE, ZERO
215    o eesupp/src:
216       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
217    o pkg/seaice/seaice_growth.F
218      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
219      merging process. The merged routine has two branches, and one activates the 'evolution'
220      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
221      In summary, here is what the '10/10 revision' did consist of
222        part 1: seaice_growth.F revisions 1.71 to 1.75
223          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
224            The emphasis here was on improving readability (e.g. by trying to use meaningful
225            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
226        part 1.5:
227          - revising the lab_sea experiment to make it a more useful (i.e. stable
228            and representative of an actual model run). This was done by generating a
229            (winter) pickup to start from, switching back the main experiment dynamic
230            solver from evp to lsr, having one of the experiments use the free drift solution.
231        part 2: seaice_growth.F revisions 1.76 to 1.85
232          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
233          - Sorting out the various fields units and sign (set early on and reset at the end)
234            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
235            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
236          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
237            and simplifying logical expressions to further improve readibility.
238        part 3: seaice_growth.F revisions 1.86 to 1.89
239          - Re-organize the blocks of code more logically.
240          - Merging the '_if.F' pieces that add something new.
241    o pkg/thsice:
242      - vectorize thsice_solve4temp and thsice_get_exf.
243        Problem: thsice_solve4temp has an unvectorizable statement that
244        might also be problematic for TAF
245      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
246        does not change the verifcation experiment, but will change all
247        experiments that have this flag undefined (not tested in verification);
248        a little reorganization to save a few 2D fields and recomputations
249      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
250      - 2nd step:  fix some store dirs
251        o seems to work somewhat, i.e. using ifort but not g77
252        o likely cause are incomplete init. or recomputation
253        o start verification/global_ocean.cs32x15/input_ad.thsice
254    o pkg/obcs: add support for exch2
255      - the position of the boundary and prescribed values are specified using
256        a global domain with exch2 facets stacked
257        - in x for N,S boundaries (like W2_mapIO=-1)
258        - in y for E,W boundaries (so E,W boundaries do not overlap)
259    o pkg/mdsio: add support for writing global sections with exch2
260        file layout is as for obcs described above:
261        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
262        - for y-z sections, facets are stacked in y
263    o pkg/thsice:
264       - change a few routines for better vectorization: thsice_albedo.F,
265         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
266         not affected, but in particular the latter routine has changed
267         dramatically (not necessarily easier to read now).
268       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
269       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
270    o verification/lab_sea:
271      - overhaul of the forward model experiments. The main motivation
272        for this revision is that lab_sea has proven quite fragile (when
273        changing the sea-ice code, and switching platforms) to a point
274        when failures were very hard to attribute to specific code problems.
275      - the suspected reason for this fragility is noise amplification by evp so,
276        to start with, we decided to replace evp with lsr in the main experiment.
277      - the input.lsr experiment thus became obsolete and was removed.
278      - it was replaced with the input.fd experiment that uses an
279        analytical "free drift" solution as the ice velocity field.
280      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
281        will hopefully allow us to discriminate problems due to dynamic solvers
282        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
283        us to test additional options, along with the salt plume package.
284      - Finally a pickup was generated (at the end of a one year run) to
285        make the tests more representative of an actual model run. Previously
286        the tests starting point was a 1m thickness of ice everywhere.
287    o pkg/seaice:
288      - introducing S\R seaice_freedrift.F that compute the
289        analytical solution to an approximate ice momentum
290        equation (i.e. the simple stress/coriolis balance).
291      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
292        of the free drift velocity field, and enable its use.
293        To actually use the free drift solution as the model ice
294        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
295    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
296    
297    checkpoint62l (2010/10/04)
298    o pkg/seaice:
299      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
300      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
301       version (with USE_ORIGINAL_SBI undef);
302    o add hooks for new packages OASIS, the package will follow
303      (hooks exclude the seaice pkg for now)
304    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
305      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
306      rather than mdsio_readvector.F/mdsio_writevector.F, within
307      adread_adwrite.F to read/write adjoint-related tapes to disk.
308    o eesupp and pkg/mdsio: ALLOW_WHIO
309      Option to write/read 2D fields to files including tiles halos.
310      The main purpose is for adjoint related "tape I/O".
311      The secondary purpose is for debugging phases.
312      A word on those rather specifically intended purposes.
313      The code was meant to be stripped down to the bare minimum.
314      Typically, there is a unique and basic mapping to the global
315      buffer (tile by tile, then proc by proc, then level by level), and
316      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
317      meant to generate user friendly outputs of various shapes and forms.
318      Rather it is intended, for the knowledgeabale developers,
319      to be largely independent of the many mdsio options, to allow
320      outputs of tiles+halos in debugging phases and in adjoint runs,
321      and to allow some flexibility in tuning (adoint) I/O depending on each
322      file system behavior. With regard to tuning, most of the potential knobs
323      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
324      to specify directories, to specify the typical size of I/O calls, etc.)
325      are not yet included, and will be added if they prove useful.
326    o pkg/seaice:
327       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
328    o pkg/seaice:
329       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
330       code (seaice_budget_ice_if.F) which enable to recover old standard
331       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
332       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
333    o model/src (rStar):
334       use simple average (not area weighted) of rStarFac at U,V point when using
335       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
336       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
337    
338    checkpoint62k (2010/09/17)
339    o adjoint
340       * changed verification/global_ocean.cs32x15 ; adjoint now tests
341         Adams-Bashforth 3 + NLFS + RSTAR
342       * some more modifs required for ECCO-GODAE v4
343    o pkg/seaice
344       add SEAICE_AGE_VOL option to use volume instead of area for
345       integrating SEAICE_AGE
346    o model/src:
347       first check-in of sigma & hybrid-sigma coordinate code ; also includes
348       non-linear free-surface parts ; but pressure-gradient not yet coded.
349    o pkg/ptracers:
350       option for ptracer to convert Salt Relax into additional EmP.
351        tested in exp. global_ocean.90x40x15.dwnslp (update output)
352    
353    checkpoint62j (2010/08/25)
354    o pkg/ggl90:
355       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
356    o pkg/dic: car_flux.F, phos_flux.F
357      - reduce number of exp-calls in order to improve performance
358      - clean up a little (replace fields by their macros, etc., fix
359        typo in CPP-flag)
360    o pkg/ggl90: minor changes
361      - GGL90diffKrS was removed --> always use GGL90diffKr
362      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
363      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
364        (commented out for now)
365      - change in max/min operations to ensure that smoothing is ok
366      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
367      - always use diffKrNrT as background profile (i.e. never use diffKr field)
368    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
369  o pkg/dic:  o pkg/dic:
370      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
371        vectorization
372    - small bug fix in insol for the unlikely case of a cartesian grid    - small bug fix in insol for the unlikely case of a cartesian grid
373    - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F    - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
