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