4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjoint
8       * changed verification/global_ocean.cs32x15 ; adjoint now tests
9         Adams-Bashforth 3 + NLFS + RSTAR
10       * some more modifs required for ECCO-GODAE v4
11    o pkg/seaice
12       add SEAICE_AGE_VOL option to use volume instead of area for
13       integrating SEAICE_AGE
14    o model/src:
15       first check-in of sigma & hybrid-sigma coordinate code ; also includes
16       non-linear free-surface parts ; but pressure-gradient not yet coded.
17    o pkg/ptracers:
18       option for ptracer to convert Salt Relax into additional EmP.
19        tested in exp. global_ocean.90x40x15.dwnslp (update output)
20    
21    checkpoint62j (2010/08/25)
22    o pkg/ggl90:
23       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
24    o pkg/dic: car_flux.F, phos_flux.F
25      - reduce number of exp-calls in order to improve performance
26      - clean up a little (replace fields by their macros, etc., fix
27        typo in CPP-flag)
28    o pkg/ggl90: minor changes
29      - GGL90diffKrS was removed --> always use GGL90diffKr
30      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
31      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
32        (commented out for now)
33      - change in max/min operations to ensure that smoothing is ok
34      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
35      - always use diffKrNrT as background profile (i.e. never use diffKr field)
36    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
37    o pkg/dic:
38      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
39        vectorization
40      - small bug fix in insol for the unlikely case of a cartesian grid
41      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
42        + now vectorize, which also removes adjoint recomputations;
43        + replace integer maksp1 by _RL maskp1
44        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
45    
46    checkpoint62i (2010/07/21)
47    o pkg/flt:
48      - with OBCS: stop floats which enter the OB region
49    o model/src:
50      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
51        for implicit vertical advection.
52    o pkg/seaice:
53     - account for melting in seaice age evolution.
54     - remove double counting of seaice ridging effect on seaice age.
55    
56    checkpoint62h (2010/06/18)
57    o pkg/exch2:
58     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
59    o tools/genmake2
60      - remove "-pdefault" option: redundant with the use of "packages.conf";
61      - remove file pkg/pkg_default : set the default as a pkg group
62        ("default_pkg_list") defined in pkg/pkg_groups;
63      - fix for case pkg/pkg_depend is missing (was hanging before);
64      - add option "-pgroups" to specify a different pkg_groups than the default.
65    o verification/adjustment.cs-32x32x1:
66       add a "minimal" set-up test (code_min & input_min) which only compiles
67       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
68    o tools/genmake2
69      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
70      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
71    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
72      files are nearly the same anyway.
73      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
74       - redefinition of tau(i,i) (by a factor of ustar)
75       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
76       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
77       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
78       - replace
79         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
80         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
81         by
82         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
83         (changes results)
84       -> exf_bulkformulae v1.22,
85          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
86          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
87                    output.txt 1.63
88           offline_exf_seaice: output.seaicetd.txt 1.7
89           seaice_obcs: output.txt 1.10)
90      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
91       -> exf_bulkformulae v1.23,
92          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
93          and global_ocean.cs32x15.icedyn (only 11 matching digits)
94      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
95    o adjoint of exch-1:
96     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
97       (note: was already like this when using EXCH-2) and remove flow dir
98       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
99     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
100     - update pkg/exch2 diff list.
101    
102    checkpoint62g (2010/05/19)
103    o eesupp/src (exch-1):
104     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
105       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
106       (renamed to exch1_*rx_cube.F).
107     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
108       to call new exch1 S/R ; update Makefile and .cvsignore.
109     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
110       exch2_xy_rx later)
111      Note: after updating your code, need to run "make clean" in eesupp/src
112    o test experiment bottom_ctrl_5x5:
113       new output_adm.txt with fewer grdchk & less monitor output.
114    o model/src:
115      remove the call to ini_cori in initialise_varia.F (just keep the usual one
116       in initialise_fixed.F). More consistent with coriolis & horizontal grid
117       beeing treated in the same way (ini_grid is not called a 2nd time).
118    o pkg/exf:
119      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
120      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
121      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
122      - cosmetic changes to exf_bulkformulae.F to make it look more like
123        exf_bulk_largeyeager04.F
124    o eesupp/src (exch-1):
125      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
126      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
127        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
128        (even without using MPI).
129      - Message mode: move RecvAck setting (indicator of buffer being ready)
130        from send_put to recv_get S/R (was useless before, but not sure if
131        it's much more useful now);
132      - Switch the order of sync: MPI-proc 1rst and then threads;
133      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
134      - fix AD code for communication mode ='get' (but not used).
135    o model/src:
136      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
137      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
138    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
139    o pkg/ctrl: require a specific set of control variables and exf-flags for
140      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
141    o model/src:
142     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
143       1rst forward sweep, to avoid over-writing output files during recomputations
144       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
145     b) 2nd version:
146      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
147      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
148         writePickupAtEnd) + seaice & ptracers output;
149      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
150    o model/src:
151      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
152    o pkg/exch2:
153      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
154      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
155    o pkg/autodiff & exch2:
156      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
157      (for now, only if ALLOW_EXCH2 is defined).
158    o pkg/autodiff:
159      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
160        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
161       + clean-up comments (_RS is not always real*4)
162      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
163      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
164        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
165    o testreport (AD-tests):
166      no longer link files from dir "../input" (1rst link files from
167      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
168    
169    checkpoint62f (2010/04/29)
170    o model/src/the_main_loop.F:
171      adjust store directives for seaice evp and multicategory according to
172      pkg/ecco/the_main_loop.F
173    o adjoint:
174      global_sum_ad was incomplete (noted many times by many people ;)
175      nice description by Jean U. as follows:
176      * allreduce(var) in global_sum.F can be interpreted as
177        reduce(sum) followed by broadcast of sum.
178      * The adjoint of that is
179        sum(adjoint) followed by broadcast(summed adjoint value)
180        or in other words, allreduce(sum, adjoint vars)
181      We were missing the sum(adjoint)!
182      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
183      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
184      The fix should produce 16-digit accuracy between
185      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
186      multi-CPU single-tile (e.g. nSx=1, nPx-2)
187      We'll probably change this yet again shortly
188    o eesupp/src:
189      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
190    o pkg/icefront
191      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
192        specification of addmass array based on a 2D field, which is added
193        at bottommost wet level at each horizontal location.
194    o model/src:
195     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
196     layout; (not always compatible with delX,delY setting; commented out for now).
197    o pkg/exch2:
198     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
199     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
200    
201    checkpoint62e (2010/04/15)
202    o pkg/obcs:
203      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
204    o pkg/dic:
205      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
206        (note: not presently tested in any forward verification exp.)
207       update tutorial_global_oce_biogeo AD output file.
208    o pkg/exf:
209      - account for the variation of albedo as a function of zenith angle
210        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
211    o build_options:
212     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
213    o pkg/dic:
214      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
215      - use binary pickup file for restart;
216      - initialise atmos-CO2 box from dic_pCO2 parameter;
217      - fix multi-threaded.
218    o pkg/rbcs:
219     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
220       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
221     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
222       and update output.txt
223    o pkg/kpp:
224     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
225     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
226       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
227       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
228     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
229       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
230    o pkg/offline:
231      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
232      (bug was added in version 1.10 on 2007-08-23).
233    o pkg/offline:
234      - no need to specify periodicExternalForcing, etc ... to use offline pack
235      - offline input files no longer just single prec --> parameter offlineLoadPrec
236    o verification/lab_sea:
237      change AD test to multi-tile setup and update all 4 AD output.
238      NOTE: while cost function values remain very similar,
239      gradients are very different, although gradient checks are self-consistent
240      Should try to get to the bottom of this (cost function summation order?)
241    o pkg/dic:
242      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
243      a weakness of TAF that drops part of double precision in log10 derivative.
244      <= changes removed since problem has been fixed in current TAF version 1.9.71
245      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
246    o pkg/ecco:
247      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
248      update all 4 lab_sea AD output.
249    
250    checkpoint62d (2010/03/22)
251    o build_options:
252      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
253    o remove unbalanced quote (single or double) in commented line of source code
254      (may cause some warning with some preprocessor/makedepend versions).
255    o pkg/seaice:
256      fix seaice_model.F for adjoint (gael) and update AD results of experiments
257       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
258    o testreport:
259      add option '-runonly' (short: '-ro') to just do the run part (without make).
260    o eesupp: remove JAM communication code (obsolete).
261    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
262      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
263      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
264      (update also the output).
265    
266    checkpoint62c (2010/03/02)
267    o tools/build_options :
268       move (some) old optfiles from build_options/ to build_options/unsupported/
269    o model/src and pkg/exf
270       surface relaxation -- separating data and data.exf options
271       The point is to ensure that we specify the surface relaxation
272       either in data or in data.exf (but not half and half) and to
273       avoid an accidental relaxation to 0 (which happened if a time
274       scale was specified but the file name was left empty)
275    o model/src model/inc and pkg/mom_common
276       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
277       => addition to the viscosity field as computed by others schemes
278    o tools/build_options:
279      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
280        but keep the former optfile for few weeks for smooth transition
281    o pkg/ecco
282      - allow user defined cost function contributions
283            CPP: ALLOW_USERCOST_CONTRIBUTION
284            USAGE: compute contributions in cost_usercost_all.F
285      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
286          the two options are complementary.
287    o pkg/smooth
288      - migration from contrib to the main repository
289    
290    checkpoint62b (2010/01/26)
291    o pkg/monitor:
292      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
293        (in case someone forgot to update customized pieces of code)
294    o nonHydrostatic:
295      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
296      - add a simple 2-D experiment (short_surf_wave) to test it.
297    o pkg/icefront:
298       adding the shell of, and the hooks to, a new package that
299       will model melting and freezing of vertical glacier ice fronts
300    o momentum:
301      add diagnostics of momentum tendency from Hydrostatic pressure gradient
302       (without surf.pressure term: would need a 2nd filling since implicit term).
303    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
304      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
305      cannot deal with the former
306    o cleaning:
307      - remove all (except OpenAD) old TLM output from results_ad dirs.
308      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
309      - comment out maskH definition (replaced by maskInC)
310    o pkg/monitor:
311      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
312        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
313    
314    checkpoint62a (2010/01/15)
315    o model/src:
316      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
317    o pkg/diagnostics:
318      - add optional level number diagnostics (i.e., level number to be define
319        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
320      - strictly check for valid parser-code(10) ;
321      - check if adding diag to the list from the right place.
322    o pkg/longstep:
323      - change parameters and fix tracer conservation with rstar/nonlinear free surface
324    o diagnostics:
325     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
326       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
327  o pkg/diagnostics:  o pkg/diagnostics:
328   - Add option for writing vertical integral (sum of selected levels) of an output   - Add option for writing vertical integral (sum of selected levels) of an output
329      field instead of writing output field levels. Activate this option on a per      field instead of writing output field levels. Activate this option on a per
