4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src, coriolis setting:
8      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
9        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
10        files (selectCoriMap=3) with any grid.
11      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
12    o pkg/seaice/seaice_growth.F:
13        a few cosmetic changes that reduce the number of lines of code
14    o pkg/obcs: add boundary conditions following Stevens (1990)
15      - the code follows old MOM/NAOSIM code
16      - so far it is only implemented for the eastern and western boundaries
17        and NOT for pTracers
18    o pkg/rbcs:
19      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
20        beginning of the first rbcs forcing period.
21      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
22        offline package, i.e., one file per time, labeled by iteration number;
23        deltaTrbcs sets the timestep with which the data was generated;
24        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
25      - rbcsForcingCycle=0 makes forcing non-cyclic.
26      - make arithmetic safe for negative times and odd forcing periods.
27    
28    checkpoint62n (2010/11/09)
29    o pkg/seaice:
30        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
31    o pkg/obcs:
32       New S/R to copy tracer value from the OB location to narrow band region
33        (width = same as overlap) beyond the OB: preserve OB value (needed for
34        high-order scheme) which were overwritten by EXCH call if in overlap
35        region. Applied to theta, salt, ptracer and advected seaice variables.
36       With seaice: use maskInC in similar way as in gad_advection.F,
37        in seaice_advection.F and advect.F.
38       Update output of experiment seaice_obcs and change exp4 to test OBCS with
39        4th order Adv.Scheme. for pasive salt and ptracer.
40    o tools/genmake2:
41      - when looking for an optfile (not specified), only search for Fortran compiler
42        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
43      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
44        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
45      - set default for CPP to "cpp -traditional -P" (was the case without specifying
46        an optfile, but otherwise default was just "cpp".
47      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
48      - when "CC" is not set in the optfile, look for possible C compiler
49        (instead of just setting CC=cc)
50      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
51        => add a ".F" to ".o" rule for source files with no "#include" (such as
52           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
53      - move gfortran before g77 in list of possible Fortran compiler (consistent
54        with reference compiler switch from g77 to gfortran)
55    o pkg/seaice:
56      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
57        seaice_check that stops the model, when the CPP flag is used.
58      o seaice_growth.F: make capping of ice volume conserving by returning the
59        capped ice as freshwater to EmPmR. This does not change the verification
60        experiments but will change runs where the capping is acutally active
61    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
62      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
63         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
64         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
65    o tools/genmake2:
66      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
67      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
68      - clean previous genmake log files before anything else.
69      - change Makefile to remove testreport log files (*.tr_log) and genmake log
70        files only with "CLEAN" target (instead of "Clean");
71    o pkg/generic_advdiff:
72      Change OBCS in multiDim advection (gad_advection.F):
73       Use maskInC to prevent intermediate update of tracer-field in OB regions,
74       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
75       which were applying future time-step OB values.
76      This way, all explicit calculations use current-time-step OB values
77       (simpler and more consistent).
78      Affects results when set-up uses time-varying OBC and multi-dim advection;
79       update output of experiment seaice_obcs.
80    o pkg/seaice:
81      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
82       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
83         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
84      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
85       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
86       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
87    o pkg aim (2010/10/26):
88      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
89        formulation with obliquity, eccentricity, ... as run-time parameters,
90      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
91        upward shortwave radition at the surface (all-sky and clear-sky).
92    o pkg/obcs:
93      - writing sections with globalFiles=T does not work: switch to tiled-files
94        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
95      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
96      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
97    
98    checkpoint62m (2010/10/21)
99    o pkg/seaice: vectorize seaice_solve4temp.F
100      - move iterations loops outside of i/j-loops
101      - requires 2D arrays for TB and effConduct
102      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
103        modified in this routine
104      - a little bit of clean up, adjusting indentation, etc.
105      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
106        performance and '**TWO' by '**2' (because TWO is a float),
107        replaced ONE, ZERO
108    o eesupp/src:
109       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
110    o pkg/seaice/seaice_growth.F
111      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
112      merging process. The merged routine has two branches, and one activates the 'evolution'
113      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
114      In summary, here is what the '10/10 revision' did consist of
115        part 1: seaice_growth.F revisions 1.71 to 1.75
116          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
117            The emphasis here was on improving readability (e.g. by trying to use meaningful
118            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
119        part 1.5:
120          - revising the lab_sea experiment to make it a more useful (i.e. stable
121            and representative of an actual model run). This was done by generating a
122            (winter) pickup to start from, switching back the main experiment dynamic
123            solver from evp to lsr, having one of the experiments use the free drift solution.
124        part 2: seaice_growth.F revisions 1.76 to 1.85
125          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
126          - Sorting out the various fields units and sign (set early on and reset at the end)
127            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
128            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
129          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
130            and simplifying logical expressions to further improve readibility.
131        part 3: seaice_growth.F revisions 1.86 to 1.89
132          - Re-organize the blocks of code more logically.
133          - Merging the '_if.F' pieces that add something new.
134    o pkg/thsice:
135      - vectorize thsice_solve4temp and thsice_get_exf.
136        Problem: thsice_solve4temp has an unvectorizable statement that
137        might also be problematic for TAF
138      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
139        does not change the verifcation experiment, but will change all
140        experiments that have this flag undefined (not tested in verification);
141        a little reorganization to save a few 2D fields and recomputations
142      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
143      - 2nd step:  fix some store dirs
144        o seems to work somewhat, i.e. using ifort but not g77
145        o likely cause are incomplete init. or recomputation
146        o start verification/global_ocean.cs32x15/input_ad.thsice
147    o pkg/obcs: add support for exch2
148      - the position of the boundary and prescribed values are specified using
149        a global domain with exch2 facets stacked
150        - in x for N,S boundaries (like W2_mapIO=-1)
151        - in y for E,W boundaries (so E,W boundaries do not overlap)
152    o pkg/mdsio: add support for writing global sections with exch2
153        file layout is as for obcs described above:
154        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
155        - for y-z sections, facets are stacked in y
156    o pkg/thsice:
157       - change a few routines for better vectorization: thsice_albedo.F,
158         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
159         not affected, but in particular the latter routine has changed
160         dramatically (not necessarily easier to read now).
161       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
162       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
163    o verification/lab_sea:
164      - overhaul of the forward model experiments. The main motivation
165        for this revision is that lab_sea has proven quite fragile (when
166        changing the sea-ice code, and switching platforms) to a point
167        when failures were very hard to attribute to specific code problems.
168      - the suspected reason for this fragility is noise amplification by evp so,
169        to start with, we decided to replace evp with lsr in the main experiment.
170      - the input.lsr experiment thus became obsolete and was removed.
171      - it was replaced with the input.fd experiment that uses an
172        analytical "free drift" solution as the ice velocity field.
173      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
174        will hopefully allow us to discriminate problems due to dynamic solvers
175        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
176        us to test additional options, along with the salt plume package.
177      - Finally a pickup was generated (at the end of a one year run) to
178        make the tests more representative of an actual model run. Previously
179        the tests starting point was a 1m thickness of ice everywhere.
180    o pkg/seaice:
181      - introducing S\R seaice_freedrift.F that compute the
182        analytical solution to an approximate ice momentum
183        equation (i.e. the simple stress/coriolis balance).
184      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
185        of the free drift velocity field, and enable its use.
186        To actually use the free drift solution as the model ice
187        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
188    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
189    
190    checkpoint62l (2010/10/04)
191    o pkg/seaice:
192      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
193      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
194       version (with USE_ORIGINAL_SBI undef);
195    o add hooks for new packages OASIS, the package will follow
196      (hooks exclude the seaice pkg for now)
197    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
198      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
199      rather than mdsio_readvector.F/mdsio_writevector.F, within
200      adread_adwrite.F to read/write adjoint-related tapes to disk.
201    o eesupp and pkg/mdsio: ALLOW_WHIO
202      Option to write/read 2D fields to files including tiles halos.
203      The main purpose is for adjoint related "tape I/O".
204      The secondary purpose is for debugging phases.
205      A word on those rather specifically intended purposes.
206      The code was meant to be stripped down to the bare minimum.
207      Typically, there is a unique and basic mapping to the global
208      buffer (tile by tile, then proc by proc, then level by level), and
209      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
210      meant to generate user friendly outputs of various shapes and forms.
211      Rather it is intended, for the knowledgeabale developers,
212      to be largely independent of the many mdsio options, to allow
213      outputs of tiles+halos in debugging phases and in adjoint runs,
214      and to allow some flexibility in tuning (adoint) I/O depending on each
215      file system behavior. With regard to tuning, most of the potential knobs
216      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
217      to specify directories, to specify the typical size of I/O calls, etc.)
218      are not yet included, and will be added if they prove useful.
219    o pkg/seaice:
220       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
221    o pkg/seaice:
222       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
223       code (seaice_budget_ice_if.F) which enable to recover old standard
224       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
225       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
226    o model/src (rStar):
227       use simple average (not area weighted) of rStarFac at U,V point when using
228       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
229       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
230    
231    checkpoint62k (2010/09/17)
232    o adjoint
233       * changed verification/global_ocean.cs32x15 ; adjoint now tests
234         Adams-Bashforth 3 + NLFS + RSTAR
235       * some more modifs required for ECCO-GODAE v4
236    o pkg/seaice
237       add SEAICE_AGE_VOL option to use volume instead of area for
238       integrating SEAICE_AGE
239    o model/src:
240       first check-in of sigma & hybrid-sigma coordinate code ; also includes
241       non-linear free-surface parts ; but pressure-gradient not yet coded.
242    o pkg/ptracers:
243       option for ptracer to convert Salt Relax into additional EmP.
244        tested in exp. global_ocean.90x40x15.dwnslp (update output)
245    
246    checkpoint62j (2010/08/25)
247    o pkg/ggl90:
248       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
249    o pkg/dic: car_flux.F, phos_flux.F
250      - reduce number of exp-calls in order to improve performance
251      - clean up a little (replace fields by their macros, etc., fix
252        typo in CPP-flag)
253    o pkg/ggl90: minor changes
254      - GGL90diffKrS was removed --> always use GGL90diffKr
255      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
256      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
257        (commented out for now)
258      - change in max/min operations to ensure that smoothing is ok
259      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
260      - always use diffKrNrT as background profile (i.e. never use diffKr field)
261    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
262    o pkg/dic:
263      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
264        vectorization
265      - small bug fix in insol for the unlikely case of a cartesian grid
266      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
267        + now vectorize, which also removes adjoint recomputations;
268        + replace integer maksp1 by _RL maskp1
269        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
270    
271    checkpoint62i (2010/07/21)
272    o pkg/flt:
273      - with OBCS: stop floats which enter the OB region
274    o model/src:
275      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
276        for implicit vertical advection.
277    o pkg/seaice:
278     - account for melting in seaice age evolution.
279     - remove double counting of seaice ridging effect on seaice age.
280    
281    checkpoint62h (2010/06/18)
282    o pkg/exch2:
283     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
284    o tools/genmake2
285      - remove "-pdefault" option: redundant with the use of "packages.conf";
286      - remove file pkg/pkg_default : set the default as a pkg group
287        ("default_pkg_list") defined in pkg/pkg_groups;
288      - fix for case pkg/pkg_depend is missing (was hanging before);
289      - add option "-pgroups" to specify a different pkg_groups than the default.
290    o verification/adjustment.cs-32x32x1:
291       add a "minimal" set-up test (code_min & input_min) which only compiles
292       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
293    o tools/genmake2
294      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
295      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
296    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
297      files are nearly the same anyway.
298      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
299       - redefinition of tau(i,i) (by a factor of ustar)
300       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
301       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
302       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
303       - replace
304         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
305         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
306         by
307         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
308         (changes results)
309       -> exf_bulkformulae v1.22,
310          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
311          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
312                    output.txt 1.63
313           offline_exf_seaice: output.seaicetd.txt 1.7
314           seaice_obcs: output.txt 1.10)
315      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
316       -> exf_bulkformulae v1.23,
317          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
318          and global_ocean.cs32x15.icedyn (only 11 matching digits)
319      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
320    o adjoint of exch-1:
321     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
322       (note: was already like this when using EXCH-2) and remove flow dir
323       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
324     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
325     - update pkg/exch2 diff list.
326    
327    checkpoint62g (2010/05/19)
328    o eesupp/src (exch-1):
329     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
330       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
331       (renamed to exch1_*rx_cube.F).
332     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
333       to call new exch1 S/R ; update Makefile and .cvsignore.
334     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
335       exch2_xy_rx later)
336      Note: after updating your code, need to run "make clean" in eesupp/src
337    o test experiment bottom_ctrl_5x5:
338       new output_adm.txt with fewer grdchk & less monitor output.
339    o model/src:
340      remove the call to ini_cori in initialise_varia.F (just keep the usual one
341       in initialise_fixed.F). More consistent with coriolis & horizontal grid
342       beeing treated in the same way (ini_grid is not called a 2nd time).
343    o pkg/exf:
344      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
345      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
346      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
347      - cosmetic changes to exf_bulkformulae.F to make it look more like
348        exf_bulk_largeyeager04.F
349    o eesupp/src (exch-1):
350      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
351      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
352        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
353        (even without using MPI).
354      - Message mode: move RecvAck setting (indicator of buffer being ready)
355        from send_put to recv_get S/R (was useless before, but not sure if
356        it's much more useful now);
357      - Switch the order of sync: MPI-proc 1rst and then threads;
358      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
359      - fix AD code for communication mode ='get' (but not used).
360    o model/src:
361      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
362      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
363    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
364    o pkg/ctrl: require a specific set of control variables and exf-flags for
365      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
366    o model/src:
367     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
368       1rst forward sweep, to avoid over-writing output files during recomputations
369       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
370     b) 2nd version:
371      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
372      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
373         writePickupAtEnd) + seaice & ptracers output;
374      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
375    o model/src:
376      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
377    o pkg/exch2:
378      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
379      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
380    o pkg/autodiff & exch2:
381      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
382      (for now, only if ALLOW_EXCH2 is defined).
383    o pkg/autodiff:
384      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
385        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
386       + clean-up comments (_RS is not always real*4)
387      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
388      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
389        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
390    o testreport (AD-tests):
391      no longer link files from dir "../input" (1rst link files from
392      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
393    
394    checkpoint62f (2010/04/29)
