# Line 5  $Name$ Line 5  $Name$
5      ==============================      ==============================
6    
7  o model/src:  o model/src:
8      - check horizontal grid-spacing for unset or zero/negative values.
9      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
10    o pkg/flt:
11      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
12      - precision of input and output files set according to readBinaryPrec
13        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
14      - initial float position from tiled file was not converted to index space
15        (looks like a bug): fixed to make it similar to initial pos. global file.
16    o global_ocean.cs32x15:
17       change SIZE.h of AD set-up to get same tiling as with MPI.
18       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
19    o model/src:
20       add flag to control printing of domain fields (bathymetry, hFac ...) in
21       ini_mask_etc (call to plot_fieds_xy*).
22    o pkg/thsice:
23       if useEXF, some forcing fields are not valid in overlap: fixed by computing
24       over the interior only + apply EXCH at the end (like with SEAICE advection).
25    o pkg/mdsio:
26      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
27        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
28      - change barrier call for safe multi-threads access to 3-D shared buffer.
29      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
30      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
31        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
32    o pkg/flt:
33      - add fourth-order Runge-Kutta integration
34      - add basic exch2 support (only 1 facet supported so far!)
35    o pkg/mdsio+rw:
36      new S/R to read local (or tile independent) vector (read counterpart of
37       mds_writevec_loc, and front-end write_glvec_rl/rs).
38    o global_ocean.cs32x15: additional input_ad.seaice experiment
39        that uses pkg/seaice rather than pkg/thsice.
40        (using multidim advection for seaice)
41    o towards more F95 syntax for array specification in namelist:
42      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
43        of all verification experiments.
44           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
45          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
46      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
47    o global_ocean.cs32x15: additional input.seaice experiment
48        that uses pkg/seaice rather than pkg/thsice.
49    
50    checkpoint62p (2010/12/17)
51    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
52        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
53    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
54        allow for use of multim. advection in seaice adjoint.
55    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
56      - first attempt to close budgets by taking into account the freshwater
57        flux implied by the sublimation of snow and ice. So far only the
58        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
59        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
60    o eesupp/src:
61      new S/R with new option (NML_EXTENDED_F77) to change array specification
62      from F95 standard to commonly accepted extended F77 form.
63      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
64      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
65      for less tolerant f77 compiler (e.g., pgf77, g77).
66    o globalFiles:
67      commented out in parameter file "data" since it's not safe with MPI
68      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
69      in this case); no longer commented out in restart test (tst_2+2).
70    o add adTapeDir to specify a special directory where adjoint tapes are
71      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
72      and cannot be used together with mdsioLocalDir.
73    o nesting pkgs:
74      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
75      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
76      - add parameter files + utils dir + output from short run on beagle.
77    o pkg/seaice:
78        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
79    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
80      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
81    
82    checkpoint62o (2010/11/25)
83    o pkg/exf:
84      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
85    o pkg/seaice:
86      - seaice_ocean_stress: split a loop for better vectorization of the
87        adjoint code
88      - seaice_growth.F: fix bug in conservation of freshwater connected to
89        capping of heff, put contribution into d_HEFFbyNEG
90      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
91        by something more sensible (parameters that are what their name implies)
92      - change some defaults, so that by default exf-parameters are used for
93        things like rhoAir, cpAir,latent/sensible heat parameters, in order
94        to reproduce the old results, many data.seaice now contain funny values
95        for cpAir and latent heat of sublimation
96    o packages_readparms.F: move exf_readparms up in line so that
97        exf-parameters are visible for other packages (e.g. seaice)
98    o debugMode & debugLevel=2:
99      - differentiate between debugMode & debugLevel=2:
100        debugMode: controls printing of debug messages (sequence of S/R calls).
101        debugLevel: controls printing of algorithm intermediate results and stats.
102      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
103        => allows to print debug-stats without all sequence of call messages.
104      - switch control of debug print from debugLevel to debugMode in many S/R.
105    o pkg/obcs (obcs-sponge):
106        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
107        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
108    o pkg/generic_advdiff:
109      - record overlap minimum size for each advection scheme;
110      - refine criteria on overlap minimum size;
111      - check and stop (in gad_check) if overlap size is too small.
112    o pkg/obcs:
113      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
114        once, in ptracers_implicit.F)
115      - with seaice: remove test on empty file name in obcs_apply_seaice (always
116        apply OB values when tile has OB)
117    o model/src, coriolis setting:
118      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
119        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
120        files (selectCoriMap=3) with any grid.
121      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
122    o pkg/seaice/seaice_growth.F:
123        a few cosmetic changes that reduce the number of lines of code
124    o pkg/obcs: add boundary conditions following Stevens (1990)
125      - the code follows old MOM/NAOSIM code
126      - so far it is only implemented for the eastern and western boundaries
127        and NOT for pTracers
128    o pkg/rbcs:
129      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
130        beginning of the first rbcs forcing period.
131      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
132        offline package, i.e., one file per time, labeled by iteration number;
133        deltaTrbcs sets the timestep with which the data was generated;
134        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
135      - rbcsForcingCycle=0 makes forcing non-cyclic.
136      - make arithmetic safe for negative times and odd forcing periods.
137    
138    checkpoint62n (2010/11/09)
139    o pkg/seaice:
140        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
141    o pkg/obcs:
142       New S/R to copy tracer value from the OB location to narrow band region
143        (width = same as overlap) beyond the OB: preserve OB value (needed for
144        high-order scheme) which were overwritten by EXCH call if in overlap
145        region. Applied to theta, salt, ptracer and advected seaice variables.
146       With seaice: use maskInC in similar way as in gad_advection.F,
147        in seaice_advection.F and advect.F.
148       Update output of experiment seaice_obcs and change exp4 to test OBCS with
149        4th order Adv.Scheme. for pasive salt and ptracer.
150    o tools/genmake2:
151      - when looking for an optfile (not specified), only search for Fortran compiler
152        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
153      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
154        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
155      - set default for CPP to "cpp -traditional -P" (was the case without specifying
156        an optfile, but otherwise default was just "cpp".
157      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
158      - when "CC" is not set in the optfile, look for possible C compiler
159        (instead of just setting CC=cc)
160      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
161        => add a ".F" to ".o" rule for source files with no "#include" (such as
162           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
163      - move gfortran before g77 in list of possible Fortran compiler (consistent
164        with reference compiler switch from g77 to gfortran)
165    o pkg/seaice:
166      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
167        seaice_check that stops the model, when the CPP flag is used.
168      o seaice_growth.F: make capping of ice volume conserving by returning the
169        capped ice as freshwater to EmPmR. This does not change the verification
170        experiments but will change runs where the capping is acutally active
171    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
172      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
173         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
174         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
175    o tools/genmake2:
176      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
177      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
178      - clean previous genmake log files before anything else.
179      - change Makefile to remove testreport log files (*.tr_log) and genmake log
180        files only with "CLEAN" target (instead of "Clean");
181    o pkg/generic_advdiff:
182      Change OBCS in multiDim advection (gad_advection.F):
183       Use maskInC to prevent intermediate update of tracer-field in OB regions,
184       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
185       which were applying future time-step OB values.
186      This way, all explicit calculations use current-time-step OB values
187       (simpler and more consistent).
188      Affects results when set-up uses time-varying OBC and multi-dim advection;
189       update output of experiment seaice_obcs.
190    o pkg/seaice:
191      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
192       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
193         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
194      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
195       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
196       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
197    o pkg aim (2010/10/26):
198      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
199        formulation with obliquity, eccentricity, ... as run-time parameters,
200      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
201        upward shortwave radition at the surface (all-sky and clear-sky).
202    o pkg/obcs:
203      - writing sections with globalFiles=T does not work: switch to tiled-files
204        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
205      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
206      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
207    
208    checkpoint62m (2010/10/21)
209    o pkg/seaice: vectorize seaice_solve4temp.F
210      - move iterations loops outside of i/j-loops
211      - requires 2D arrays for TB and effConduct
212      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
213        modified in this routine
214      - a little bit of clean up, adjusting indentation, etc.
215      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
216        performance and '**TWO' by '**2' (because TWO is a float),
217        replaced ONE, ZERO
218    o eesupp/src:
219       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
220    o pkg/seaice/seaice_growth.F
221      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
222      merging process. The merged routine has two branches, and one activates the 'evolution'
223      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
224      In summary, here is what the '10/10 revision' did consist of
225        part 1: seaice_growth.F revisions 1.71 to 1.75
226          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
227            The emphasis here was on improving readability (e.g. by trying to use meaningful
228            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
229        part 1.5:
230          - revising the lab_sea experiment to make it a more useful (i.e. stable
231            and representative of an actual model run). This was done by generating a
232            (winter) pickup to start from, switching back the main experiment dynamic
233            solver from evp to lsr, having one of the experiments use the free drift solution.
234        part 2: seaice_growth.F revisions 1.76 to 1.85
235          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
236          - Sorting out the various fields units and sign (set early on and reset at the end)
237            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
238            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
239          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
240            and simplifying logical expressions to further improve readibility.
241        part 3: seaice_growth.F revisions 1.86 to 1.89
242          - Re-organize the blocks of code more logically.
243          - Merging the '_if.F' pieces that add something new.
244    o pkg/thsice:
245      - vectorize thsice_solve4temp and thsice_get_exf.
246        Problem: thsice_solve4temp has an unvectorizable statement that
247        might also be problematic for TAF
248      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
249        does not change the verifcation experiment, but will change all
250        experiments that have this flag undefined (not tested in verification);
251        a little reorganization to save a few 2D fields and recomputations
252      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
253      - 2nd step:  fix some store dirs
254        o seems to work somewhat, i.e. using ifort but not g77
255        o likely cause are incomplete init. or recomputation
256        o start verification/global_ocean.cs32x15/input_ad.thsice
257    o pkg/obcs: add support for exch2
258      - the position of the boundary and prescribed values are specified using
259        a global domain with exch2 facets stacked
260        - in x for N,S boundaries (like W2_mapIO=-1)
261        - in y for E,W boundaries (so E,W boundaries do not overlap)
262    o pkg/mdsio: add support for writing global sections with exch2
263        file layout is as for obcs described above:
264        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
265        - for y-z sections, facets are stacked in y
266    o pkg/thsice:
267       - change a few routines for better vectorization: thsice_albedo.F,
268         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
269         not affected, but in particular the latter routine has changed
270         dramatically (not necessarily easier to read now).
271       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
272       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
273    o verification/lab_sea:
274      - overhaul of the forward model experiments. The main motivation
275        for this revision is that lab_sea has proven quite fragile (when
276        changing the sea-ice code, and switching platforms) to a point
277        when failures were very hard to attribute to specific code problems.
278      - the suspected reason for this fragility is noise amplification by evp so,
279        to start with, we decided to replace evp with lsr in the main experiment.
280      - the input.lsr experiment thus became obsolete and was removed.
281      - it was replaced with the input.fd experiment that uses an
282        analytical "free drift" solution as the ice velocity field.
283      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
284        will hopefully allow us to discriminate problems due to dynamic solvers
285        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
286        us to test additional options, along with the salt plume package.
287      - Finally a pickup was generated (at the end of a one year run) to
288        make the tests more representative of an actual model run. Previously
289        the tests starting point was a 1m thickness of ice everywhere.
290    o pkg/seaice:
291      - introducing S\R seaice_freedrift.F that compute the
292        analytical solution to an approximate ice momentum
293        equation (i.e. the simple stress/coriolis balance).
294      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
295        of the free drift velocity field, and enable its use.
296        To actually use the free drift solution as the model ice
297        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
298    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
299    
300    checkpoint62l (2010/10/04)
301    o pkg/seaice:
302      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
303      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
304       version (with USE_ORIGINAL_SBI undef);
305    o add hooks for new packages OASIS, the package will follow
306      (hooks exclude the seaice pkg for now)
307    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
308      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
309      rather than mdsio_readvector.F/mdsio_writevector.F, within
310      adread_adwrite.F to read/write adjoint-related tapes to disk.
311    o eesupp and pkg/mdsio: ALLOW_WHIO
312      Option to write/read 2D fields to files including tiles halos.
313      The main purpose is for adjoint related "tape I/O".
314      The secondary purpose is for debugging phases.
315      A word on those rather specifically intended purposes.
316      The code was meant to be stripped down to the bare minimum.
317      Typically, there is a unique and basic mapping to the global
318      buffer (tile by tile, then proc by proc, then level by level), and
319      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
320      meant to generate user friendly outputs of various shapes and forms.
321      Rather it is intended, for the knowledgeabale developers,
322      to be largely independent of the many mdsio options, to allow
323      outputs of tiles+halos in debugging phases and in adjoint runs,
324      and to allow some flexibility in tuning (adoint) I/O depending on each
325      file system behavior. With regard to tuning, most of the potential knobs
326      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
327      to specify directories, to specify the typical size of I/O calls, etc.)
328      are not yet included, and will be added if they prove useful.
329    o pkg/seaice:
330       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
331    o pkg/seaice:
332       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
