4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ptracers:
8       option for ptracer to convert Salt Relax into additional EmP.
9        tested in exp. global_ocean.90x40x15.dwnslp (update output)
10    
11    checkpoint62j (2010/08/25)
12    o pkg/ggl90:
13       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
14    o pkg/dic: car_flux.F, phos_flux.F
15      - reduce number of exp-calls in order to improve performance
16      - clean up a little (replace fields by their macros, etc., fix
17        typo in CPP-flag)
18    o pkg/ggl90: minor changes
19      - GGL90diffKrS was removed --> always use GGL90diffKr
20      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
21      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
22        (commented out for now)
23      - change in max/min operations to ensure that smoothing is ok
24      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
25      - always use diffKrNrT as background profile (i.e. never use diffKr field)
26    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
27    o pkg/dic:
28      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
29        vectorization
30      - small bug fix in insol for the unlikely case of a cartesian grid
31      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
32        + now vectorize, which also removes adjoint recomputations;
33        + replace integer maksp1 by _RL maskp1
34        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
35    
36    checkpoint62i (2010/07/21)
37    o pkg/flt:
38      - with OBCS: stop floats which enter the OB region
39    o model/src:
40      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
41        for implicit vertical advection.
42    o pkg/seaice:
43     - account for melting in seaice age evolution.
44     - remove double counting of seaice ridging effect on seaice age.
45    
46    checkpoint62h (2010/06/18)
47    o pkg/exch2:
48     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
49    o tools/genmake2
50      - remove "-pdefault" option: redundant with the use of "packages.conf";
51      - remove file pkg/pkg_default : set the default as a pkg group
52        ("default_pkg_list") defined in pkg/pkg_groups;
53      - fix for case pkg/pkg_depend is missing (was hanging before);
54      - add option "-pgroups" to specify a different pkg_groups than the default.
55    o verification/adjustment.cs-32x32x1:
56       add a "minimal" set-up test (code_min & input_min) which only compiles
57       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
58    o tools/genmake2
59      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
60      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
61    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
62      files are nearly the same anyway.
63      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
64       - redefinition of tau(i,i) (by a factor of ustar)
65       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
66       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
67       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
68       - replace
69         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
70         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
71         by
72         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
73         (changes results)
74       -> exf_bulkformulae v1.22,
75          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
76          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
77                    output.txt 1.63
78           offline_exf_seaice: output.seaicetd.txt 1.7
79           seaice_obcs: output.txt 1.10)
80      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
81       -> exf_bulkformulae v1.23,
82          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
83          and global_ocean.cs32x15.icedyn (only 11 matching digits)
84      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
85    o adjoint of exch-1:
86     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
87       (note: was already like this when using EXCH-2) and remove flow dir
88       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
89     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
90     - update pkg/exch2 diff list.
91    
92    checkpoint62g (2010/05/19)
93    o eesupp/src (exch-1):
94     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
95       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
96       (renamed to exch1_*rx_cube.F).
97     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
98       to call new exch1 S/R ; update Makefile and .cvsignore.
99     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
100       exch2_xy_rx later)
101      Note: after updating your code, need to run "make clean" in eesupp/src
102    o test experiment bottom_ctrl_5x5:
103       new output_adm.txt with fewer grdchk & less monitor output.
104    o model/src:
105      remove the call to ini_cori in initialise_varia.F (just keep the usual one
106       in initialise_fixed.F). More consistent with coriolis & horizontal grid
107       beeing treated in the same way (ini_grid is not called a 2nd time).
108    o pkg/exf:
109      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
110      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
111      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
112      - cosmetic changes to exf_bulkformulae.F to make it look more like
113        exf_bulk_largeyeager04.F
114    o eesupp/src (exch-1):
115      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
116      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
117        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
118        (even without using MPI).
119      - Message mode: move RecvAck setting (indicator of buffer being ready)
120        from send_put to recv_get S/R (was useless before, but not sure if
121        it's much more useful now);
122      - Switch the order of sync: MPI-proc 1rst and then threads;
123      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
124      - fix AD code for communication mode ='get' (but not used).
125    o model/src:
126      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
127      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
128    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
129    o pkg/ctrl: require a specific set of control variables and exf-flags for
130      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
131    o model/src:
132     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
133       1rst forward sweep, to avoid over-writing output files during recomputations
134       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
135     b) 2nd version:
136      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
137      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
138         writePickupAtEnd) + seaice & ptracers output;
139      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
140    o model/src:
141      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
142    o pkg/exch2:
143      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
144      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
145    o pkg/autodiff & exch2:
146      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
147      (for now, only if ALLOW_EXCH2 is defined).
148    o pkg/autodiff:
149      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
150        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
151       + clean-up comments (_RS is not always real*4)
152      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
153      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
154        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
155    o testreport (AD-tests):
156      no longer link files from dir "../input" (1rst link files from
157      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
158    
159    checkpoint62f (2010/04/29)
160    o model/src/the_main_loop.F:
161      adjust store directives for seaice evp and multicategory according to
162      pkg/ecco/the_main_loop.F
163    o adjoint:
164      global_sum_ad was incomplete (noted many times by many people ;)
165      nice description by Jean U. as follows:
166      * allreduce(var) in global_sum.F can be interpreted as
167        reduce(sum) followed by broadcast of sum.
168      * The adjoint of that is
169        sum(adjoint) followed by broadcast(summed adjoint value)
170        or in other words, allreduce(sum, adjoint vars)
171      We were missing the sum(adjoint)!
172      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
173      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
174      The fix should produce 16-digit accuracy between
175      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
176      multi-CPU single-tile (e.g. nSx=1, nPx-2)
177      We'll probably change this yet again shortly
178    o eesupp/src:
179      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
180    o pkg/icefront
181      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
182        specification of addmass array based on a 2D field, which is added
183        at bottommost wet level at each horizontal location.
184    o model/src:
185     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
186     layout; (not always compatible with delX,delY setting; commented out for now).
187    o pkg/exch2:
188     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
189     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
190    
191    checkpoint62e (2010/04/15)
192    o pkg/obcs:
193      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
194    o pkg/dic:
195      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
196        (note: not presently tested in any forward verification exp.)
197       update tutorial_global_oce_biogeo AD output file.
198    o pkg/exf:
199      - account for the variation of albedo as a function of zenith angle
200        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
201    o build_options:
202     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
203    o pkg/dic:
204      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
205      - use binary pickup file for restart;
206      - initialise atmos-CO2 box from dic_pCO2 parameter;
207      - fix multi-threaded.
208    o pkg/rbcs:
209     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
210       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
211     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
212       and update output.txt
213    o pkg/kpp:
214     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
215     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
216       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
217       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
218     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
219       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
220    o pkg/offline:
221      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
222      (bug was added in version 1.10 on 2007-08-23).
223    o pkg/offline:
224      - no need to specify periodicExternalForcing, etc ... to use offline pack
225      - offline input files no longer just single prec --> parameter offlineLoadPrec
226    o verification/lab_sea:
227      change AD test to multi-tile setup and update all 4 AD output.
228      NOTE: while cost function values remain very similar,
229      gradients are very different, although gradient checks are self-consistent
230      Should try to get to the bottom of this (cost function summation order?)
231    o pkg/dic:
232      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
233      a weakness of TAF that drops part of double precision in log10 derivative.
234      <= changes removed since problem has been fixed in current TAF version 1.9.71
235      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
236    o pkg/ecco:
237      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
238      update all 4 lab_sea AD output.
239    
240    checkpoint62d (2010/03/22)
241    o build_options:
242      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
243    o remove unbalanced quote (single or double) in commented line of source code
244      (may cause some warning with some preprocessor/makedepend versions).
245    o pkg/seaice:
246      fix seaice_model.F for adjoint (gael) and update AD results of experiments
247       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
248    o testreport:
249      add option '-runonly' (short: '-ro') to just do the run part (without make).
250    o eesupp: remove JAM communication code (obsolete).
251    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
252      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
253      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
254      (update also the output).
255    
256    checkpoint62c (2010/03/02)
257    o tools/build_options :
258       move (some) old optfiles from build_options/ to build_options/unsupported/
259    o model/src and pkg/exf
260       surface relaxation -- separating data and data.exf options
261       The point is to ensure that we specify the surface relaxation
262       either in data or in data.exf (but not half and half) and to
263       avoid an accidental relaxation to 0 (which happened if a time
264       scale was specified but the file name was left empty)
265    o model/src model/inc and pkg/mom_common
266       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
267       => addition to the viscosity field as computed by others schemes
268    o tools/build_options:
269      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
270        but keep the former optfile for few weeks for smooth transition
271    o pkg/ecco
272      - allow user defined cost function contributions
273            CPP: ALLOW_USERCOST_CONTRIBUTION
274            USAGE: compute contributions in cost_usercost_all.F
275      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
276          the two options are complementary.
277    o pkg/smooth
278      - migration from contrib to the main repository
279    
280    checkpoint62b (2010/01/26)
281    o pkg/monitor:
282      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
283        (in case someone forgot to update customized pieces of code)
284    o nonHydrostatic:
285      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
286      - add a simple 2-D experiment (short_surf_wave) to test it.
287    o pkg/icefront:
288       adding the shell of, and the hooks to, a new package that
289       will model melting and freezing of vertical glacier ice fronts
290    o momentum:
291      add diagnostics of momentum tendency from Hydrostatic pressure gradient
292       (without surf.pressure term: would need a 2nd filling since implicit term).
293    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
294      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
295      cannot deal with the former
296    o cleaning:
297      - remove all (except OpenAD) old TLM output from results_ad dirs.
298      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
299      - comment out maskH definition (replaced by maskInC)
300    o pkg/monitor:
301      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
302        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
303    
304    checkpoint62a (2010/01/15)
305    o model/src:
306      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
307    o pkg/diagnostics:
308      - add optional level number diagnostics (i.e., level number to be define
309        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
310      - strictly check for valid parser-code(10) ;
311      - check if adding diag to the list from the right place.
312    o pkg/longstep:
313      - change parameters and fix tracer conservation with rstar/nonlinear free surface
314    o diagnostics:
315     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
316       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
317    o pkg/diagnostics:
318     - Add option for writing vertical integral (sum of selected levels) of an output
319        field instead of writing output field levels. Activate this option on a per
320        output-file basis, by setting the 2nd character of fileflag to 'I'.
321     - Add field-specific information relative to level integral in 3rd postion
322        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
323        vertically (x level-thickness x hFac), "r"=same but without hFac.
324    o do_the_model_io:
325      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
326        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
327        writing pickups and stopping.
328    o pkg/diagnostics (for now, only with mdsio):
329      - write time information to meta file (and modify accordingly rdmds.m) :
330        time-averaged diagnostics output: write starting and ending time of the
331        time-averaging interval ; snap-shot diagnostics output remains unchanged;
332    o pkg/timeave:
333      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
334        always Nr), now assumed to be equal to number of levels of averaged field;
335        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
336    o pkg/sbo:
337      - fix ocean bottom pressure global-average & 2-D time-ave output (was
338        neither initialised nor filled).
339      - add starting iteration in suffix of global-average output file
340        (to avoid over-writing the file after a restart)
341      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
342    o time-average:
343      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
344        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
345         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
346        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
347      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
348      - fix missing accumulation for pkg/opps.
349      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
350         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
351      - fix initialisation of time-ave vars and do only full time-step increment
352        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
353    o pkg/layers:
354      - use standard RW pkg S/R to write the output
355        and remove local write_fld version (which had a problem).
356      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
357      - fix LAYERS_CALC argument list.
358    o pkg/timeave:
359      - store cumulative-time in a simple tiled array (drop the level index)
360      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
361    o pkg/ocn,aim_compon_interf
362      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
363    
364    checkpoint62  (2009/12/23)
365    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
366        (was not previously tested in any other exp.)
367    o pkg/monitor:
368      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
369        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
370        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
371      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
372      - change del2 calculation.
373      - use interior masks (instead of maskH, <- to be remove).
374      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
375    o mask & obcs:
376      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
377      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
378        (called after packages_init_fixed)
379  o pkg/obcs:  o pkg/obcs:
380    - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.    - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
