4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add diagnostics for snow precipitation
8    o globalFiles:
9      commented out in parameter file "data" since it's not safe with MPI
10      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
11      in this case); no longer commented out in restart test (tst_2+2).
12    o add adTapeDir to specify a special directory where adjoint tapes are
13      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
14      and cannot be used together with mdsioLocalDir.
15    o nesting pkgs:
16      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
17      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
18      - add parameter files + utils dir + output from short run on beagle.
19    o pkg/seaice:
20        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
21    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
22      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
23    
24    checkpoint62o (2010/11/25)
25    o pkg/exf:
26      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
27    o pkg/seaice:
28      - seaice_ocean_stress: split a loop for better vectorization of the
29        adjoint code
30      - seaice_growth.F: fix bug in conservation of freshwater connected to
31        capping of heff, put contribution into d_HEFFbyNEG
32      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
33        by something more sensible (parameters that are what their name implies)
34      - change some defaults, so that by default exf-parameters are used for
35        things like rhoAir, cpAir,latent/sensible heat parameters, in order
36        to reproduce the old results, many data.seaice now contain funny values
37        for cpAir and latent heat of sublimation
38    o packages_readparms.F: move exf_readparms up in line so that
39        exf-parameters are visible for other packages (e.g. seaice)
40    o debugMode & debugLevel=2:
41      - differentiate between debugMode & debugLevel=2:
42        debugMode: controls printing of debug messages (sequence of S/R calls).
43        debugLevel: controls printing of algorithm intermediate results and stats.
44      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
45        => allows to print debug-stats without all sequence of call messages.
46      - switch control of debug print from debugLevel to debugMode in many S/R.
47    o pkg/obcs (obcs-sponge):
48        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
49        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
50    o pkg/generic_advdiff:
51      - record overlap minimum size for each advection scheme;
52      - refine criteria on overlap minimum size;
53      - check and stop (in gad_check) if overlap size is too small.
54    o pkg/obcs:
55      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
56        once, in ptracers_implicit.F)
57      - with seaice: remove test on empty file name in obcs_apply_seaice (always
58        apply OB values when tile has OB)
59    o model/src, coriolis setting:
60      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
61        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
62        files (selectCoriMap=3) with any grid.
63      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
64    o pkg/seaice/seaice_growth.F:
65        a few cosmetic changes that reduce the number of lines of code
66    o pkg/obcs: add boundary conditions following Stevens (1990)
67      - the code follows old MOM/NAOSIM code
68      - so far it is only implemented for the eastern and western boundaries
69        and NOT for pTracers
70    o pkg/rbcs:
71      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
72        beginning of the first rbcs forcing period.
73      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
74        offline package, i.e., one file per time, labeled by iteration number;
75        deltaTrbcs sets the timestep with which the data was generated;
76        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
77      - rbcsForcingCycle=0 makes forcing non-cyclic.
78      - make arithmetic safe for negative times and odd forcing periods.
79    
80    checkpoint62n (2010/11/09)
81    o pkg/seaice:
82        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
83    o pkg/obcs:
84       New S/R to copy tracer value from the OB location to narrow band region
85        (width = same as overlap) beyond the OB: preserve OB value (needed for
86        high-order scheme) which were overwritten by EXCH call if in overlap
87        region. Applied to theta, salt, ptracer and advected seaice variables.
88       With seaice: use maskInC in similar way as in gad_advection.F,
89        in seaice_advection.F and advect.F.
90       Update output of experiment seaice_obcs and change exp4 to test OBCS with
91        4th order Adv.Scheme. for pasive salt and ptracer.
92    o tools/genmake2:
93      - when looking for an optfile (not specified), only search for Fortran compiler
94        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
95      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
96        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
97      - set default for CPP to "cpp -traditional -P" (was the case without specifying
98        an optfile, but otherwise default was just "cpp".
99      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
100      - when "CC" is not set in the optfile, look for possible C compiler
101        (instead of just setting CC=cc)
102      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
103        => add a ".F" to ".o" rule for source files with no "#include" (such as
104           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
105      - move gfortran before g77 in list of possible Fortran compiler (consistent
106        with reference compiler switch from g77 to gfortran)
107    o pkg/seaice:
108      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
109        seaice_check that stops the model, when the CPP flag is used.
110      o seaice_growth.F: make capping of ice volume conserving by returning the
111        capped ice as freshwater to EmPmR. This does not change the verification
112        experiments but will change runs where the capping is acutally active
113    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
114      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
115         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
116         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
117    o tools/genmake2:
118      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
119      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
120      - clean previous genmake log files before anything else.
121      - change Makefile to remove testreport log files (*.tr_log) and genmake log
122        files only with "CLEAN" target (instead of "Clean");
123    o pkg/generic_advdiff:
124      Change OBCS in multiDim advection (gad_advection.F):
125       Use maskInC to prevent intermediate update of tracer-field in OB regions,
126       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
127       which were applying future time-step OB values.
128      This way, all explicit calculations use current-time-step OB values
129       (simpler and more consistent).
130      Affects results when set-up uses time-varying OBC and multi-dim advection;
131       update output of experiment seaice_obcs.
132    o pkg/seaice:
133      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
134       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
135         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
136      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
137       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
138       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
139    o pkg aim (2010/10/26):
140      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
141        formulation with obliquity, eccentricity, ... as run-time parameters,
142      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
143        upward shortwave radition at the surface (all-sky and clear-sky).
144    o pkg/obcs:
145      - writing sections with globalFiles=T does not work: switch to tiled-files
146        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
147      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
148      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
149    
150    checkpoint62m (2010/10/21)
151    o pkg/seaice: vectorize seaice_solve4temp.F
152      - move iterations loops outside of i/j-loops
153      - requires 2D arrays for TB and effConduct
154      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
155        modified in this routine
156      - a little bit of clean up, adjusting indentation, etc.
157      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
158        performance and '**TWO' by '**2' (because TWO is a float),
159        replaced ONE, ZERO
160    o eesupp/src:
161       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
162    o pkg/seaice/seaice_growth.F
163      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
164      merging process. The merged routine has two branches, and one activates the 'evolution'
165      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
166      In summary, here is what the '10/10 revision' did consist of
167        part 1: seaice_growth.F revisions 1.71 to 1.75
168          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
169            The emphasis here was on improving readability (e.g. by trying to use meaningful
170            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
171        part 1.5:
172          - revising the lab_sea experiment to make it a more useful (i.e. stable
173            and representative of an actual model run). This was done by generating a
174            (winter) pickup to start from, switching back the main experiment dynamic
175            solver from evp to lsr, having one of the experiments use the free drift solution.
176        part 2: seaice_growth.F revisions 1.76 to 1.85
177          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
178          - Sorting out the various fields units and sign (set early on and reset at the end)
179            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
180            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
181          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
182            and simplifying logical expressions to further improve readibility.
183        part 3: seaice_growth.F revisions 1.86 to 1.89
184          - Re-organize the blocks of code more logically.
185          - Merging the '_if.F' pieces that add something new.
186    o pkg/thsice:
187      - vectorize thsice_solve4temp and thsice_get_exf.
188        Problem: thsice_solve4temp has an unvectorizable statement that
189        might also be problematic for TAF
190      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
191        does not change the verifcation experiment, but will change all
192        experiments that have this flag undefined (not tested in verification);
193        a little reorganization to save a few 2D fields and recomputations
194      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
195      - 2nd step:  fix some store dirs
196        o seems to work somewhat, i.e. using ifort but not g77
197        o likely cause are incomplete init. or recomputation
198        o start verification/global_ocean.cs32x15/input_ad.thsice
199    o pkg/obcs: add support for exch2
200      - the position of the boundary and prescribed values are specified using
201        a global domain with exch2 facets stacked
202        - in x for N,S boundaries (like W2_mapIO=-1)
203        - in y for E,W boundaries (so E,W boundaries do not overlap)
204    o pkg/mdsio: add support for writing global sections with exch2
205        file layout is as for obcs described above:
206        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
207        - for y-z sections, facets are stacked in y
208    o pkg/thsice:
209       - change a few routines for better vectorization: thsice_albedo.F,
210         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
211         not affected, but in particular the latter routine has changed
212         dramatically (not necessarily easier to read now).
213       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
214       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
215    o verification/lab_sea:
216      - overhaul of the forward model experiments. The main motivation
217        for this revision is that lab_sea has proven quite fragile (when
218        changing the sea-ice code, and switching platforms) to a point
219        when failures were very hard to attribute to specific code problems.
220      - the suspected reason for this fragility is noise amplification by evp so,
221        to start with, we decided to replace evp with lsr in the main experiment.
222      - the input.lsr experiment thus became obsolete and was removed.
223      - it was replaced with the input.fd experiment that uses an
224        analytical "free drift" solution as the ice velocity field.
225      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
226        will hopefully allow us to discriminate problems due to dynamic solvers
227        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
228        us to test additional options, along with the salt plume package.
229      - Finally a pickup was generated (at the end of a one year run) to
230        make the tests more representative of an actual model run. Previously
231        the tests starting point was a 1m thickness of ice everywhere.
232    o pkg/seaice:
233      - introducing S\R seaice_freedrift.F that compute the
234        analytical solution to an approximate ice momentum
235        equation (i.e. the simple stress/coriolis balance).
236      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
237        of the free drift velocity field, and enable its use.
238        To actually use the free drift solution as the model ice
239        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
240    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
241    
242    checkpoint62l (2010/10/04)
243    o pkg/seaice:
244      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
245      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
246       version (with USE_ORIGINAL_SBI undef);
247    o add hooks for new packages OASIS, the package will follow
248      (hooks exclude the seaice pkg for now)
249    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
250      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
251      rather than mdsio_readvector.F/mdsio_writevector.F, within
252      adread_adwrite.F to read/write adjoint-related tapes to disk.
253    o eesupp and pkg/mdsio: ALLOW_WHIO
254      Option to write/read 2D fields to files including tiles halos.
255      The main purpose is for adjoint related "tape I/O".
256      The secondary purpose is for debugging phases.
257      A word on those rather specifically intended purposes.
258      The code was meant to be stripped down to the bare minimum.
259      Typically, there is a unique and basic mapping to the global
260      buffer (tile by tile, then proc by proc, then level by level), and
261      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
262      meant to generate user friendly outputs of various shapes and forms.
263      Rather it is intended, for the knowledgeabale developers,
264      to be largely independent of the many mdsio options, to allow
265      outputs of tiles+halos in debugging phases and in adjoint runs,
266      and to allow some flexibility in tuning (adoint) I/O depending on each
267      file system behavior. With regard to tuning, most of the potential knobs
268      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
269      to specify directories, to specify the typical size of I/O calls, etc.)
270      are not yet included, and will be added if they prove useful.
271    o pkg/seaice:
272       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
273    o pkg/seaice:
274       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
275       code (seaice_budget_ice_if.F) which enable to recover old standard
276       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
277       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
278    o model/src (rStar):
279       use simple average (not area weighted) of rStarFac at U,V point when using
280       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
281       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
282    
283    checkpoint62k (2010/09/17)
284    o adjoint
285       * changed verification/global_ocean.cs32x15 ; adjoint now tests
286         Adams-Bashforth 3 + NLFS + RSTAR
287       * some more modifs required for ECCO-GODAE v4
288    o pkg/seaice
289       add SEAICE_AGE_VOL option to use volume instead of area for
290       integrating SEAICE_AGE
291    o model/src:
292       first check-in of sigma & hybrid-sigma coordinate code ; also includes
293       non-linear free-surface parts ; but pressure-gradient not yet coded.
294    o pkg/ptracers:
295       option for ptracer to convert Salt Relax into additional EmP.
296        tested in exp. global_ocean.90x40x15.dwnslp (update output)
297    
298    checkpoint62j (2010/08/25)
299    o pkg/ggl90:
300       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
301    o pkg/dic: car_flux.F, phos_flux.F
302      - reduce number of exp-calls in order to improve performance
303      - clean up a little (replace fields by their macros, etc., fix
304        typo in CPP-flag)
305    o pkg/ggl90: minor changes
306      - GGL90diffKrS was removed --> always use GGL90diffKr
307      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
308      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
309        (commented out for now)
310      - change in max/min operations to ensure that smoothing is ok
311      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
312      - always use diffKrNrT as background profile (i.e. never use diffKr field)
313    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
314    o pkg/dic:
315      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
316        vectorization
317      - small bug fix in insol for the unlikely case of a cartesian grid
318      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
319        + now vectorize, which also removes adjoint recomputations;
320        + replace integer maksp1 by _RL maskp1
321        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
322    
323    checkpoint62i (2010/07/21)
324    o pkg/flt:
325      - with OBCS: stop floats which enter the OB region
326    o model/src:
327      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
328        for implicit vertical advection.
329    o pkg/seaice:
330     - account for melting in seaice age evolution.
331     - remove double counting of seaice ridging effect on seaice age.
332    
333    checkpoint62h (2010/06/18)
334    o pkg/exch2:
335     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
336    o tools/genmake2
337      - remove "-pdefault" option: redundant with the use of "packages.conf";
338      - remove file pkg/pkg_default : set the default as a pkg group
339        ("default_pkg_list") defined in pkg/pkg_groups;
340      - fix for case pkg/pkg_depend is missing (was hanging before);
341      - add option "-pgroups" to specify a different pkg_groups than the default.
342    o verification/adjustment.cs-32x32x1:
343       add a "minimal" set-up test (code_min & input_min) which only compiles
344       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
345    o tools/genmake2
346      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
347      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
348    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
349      files are nearly the same anyway.
350      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
351       - redefinition of tau(i,i) (by a factor of ustar)
352       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
353       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
354       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
355       - replace
356         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
357         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
358         by
359         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
360         (changes results)
361       -> exf_bulkformulae v1.22,
362          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
363          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
364                    output.txt 1.63
365           offline_exf_seaice: output.seaicetd.txt 1.7
366           seaice_obcs: output.txt 1.10)
367      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
368       -> exf_bulkformulae v1.23,
369          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
370          and global_ocean.cs32x15.icedyn (only 11 matching digits)
371      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
372    o adjoint of exch-1:
373     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
374       (note: was already like this when using EXCH-2) and remove flow dir
375       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
376     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
377     - update pkg/exch2 diff list.
378    
379    checkpoint62g (2010/05/19)
380  o eesupp/src (exch-1):  o eesupp/src (exch-1):
381   - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)   - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
382     and remove argument "simulationMode"; same thing for all exch_*rx_cube.F     and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
