4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
9      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
10       version (with USE_ORIGINAL_SBI undef);
11    o add hooks for new packages OASIS, the package will follow
12      (hooks exclude the seaice pkg for now)
13    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
14      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
15      rather than mdsio_readvector.F/mdsio_writevector.F, within
16      adread_adwrite.F to read/write adjoint-related tapes to disk.
17    o eesupp and pkg/mdsio: ALLOW_WHIO
18      Option to write/read 2D fields to files including tiles halos.
19      The main purpose is for adjoint related "tape I/O".
20      The secondary purpose is for debugging phases.
21      A word on those rather specifically intended purposes.
22      The code was meant to be stripped down to the bare minimum.
23      Typically, there is a unique and basic mapping to the global
24      buffer (tile by tile, then proc by proc, then level by level), and
25      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
26      meant to generate user friendly outputs of various shapes and forms.
27      Rather it is intended, for the knowledgeabale developers,
28      to be largely independent of the many mdsio options, to allow
29      outputs of tiles+halos in debugging phases and in adjoint runs,
30      and to allow some flexibility in tuning (adoint) I/O depending on each
31      file system behavior. With regard to tuning, most of the potential knobs
32      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
33      to specify directories, to specify the typical size of I/O calls, etc.)
34      are not yet included, and will be added if they prove useful.
35    o pkg/seaice:
36       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
37    o pkg/seaice:
38       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
39       code (seaice_budget_ice_if.F) which enable to recover old standard
40       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
41       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
42    o model/src (rStar):
43       use simple average (not area weighted) of rStarFac at U,V point when using
44       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
45       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
46    
47    checkpoint62k (2010/09/17)
48    o adjoint
49       * changed verification/global_ocean.cs32x15 ; adjoint now tests
50         Adams-Bashforth 3 + NLFS + RSTAR
51       * some more modifs required for ECCO-GODAE v4
52    o pkg/seaice
53       add SEAICE_AGE_VOL option to use volume instead of area for
54       integrating SEAICE_AGE
55    o model/src:
56       first check-in of sigma & hybrid-sigma coordinate code ; also includes
57       non-linear free-surface parts ; but pressure-gradient not yet coded.
58    o pkg/ptracers:
59       option for ptracer to convert Salt Relax into additional EmP.
60        tested in exp. global_ocean.90x40x15.dwnslp (update output)
61    
62    checkpoint62j (2010/08/25)
63    o pkg/ggl90:
64       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
65    o pkg/dic: car_flux.F, phos_flux.F
66      - reduce number of exp-calls in order to improve performance
67      - clean up a little (replace fields by their macros, etc., fix
68        typo in CPP-flag)
69    o pkg/ggl90: minor changes
70      - GGL90diffKrS was removed --> always use GGL90diffKr
71      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
72      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
73        (commented out for now)
74      - change in max/min operations to ensure that smoothing is ok
75      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
76      - always use diffKrNrT as background profile (i.e. never use diffKr field)
77    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
78    o pkg/dic:
79      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
80        vectorization
81      - small bug fix in insol for the unlikely case of a cartesian grid
82      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
83        + now vectorize, which also removes adjoint recomputations;
84        + replace integer maksp1 by _RL maskp1
85        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
86    
87    checkpoint62i (2010/07/21)
88    o pkg/flt:
89      - with OBCS: stop floats which enter the OB region
90    o model/src:
91      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
92        for implicit vertical advection.
93    o pkg/seaice:
94     - account for melting in seaice age evolution.
95     - remove double counting of seaice ridging effect on seaice age.
96    
97    checkpoint62h (2010/06/18)
98    o pkg/exch2:
99     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
100    o tools/genmake2
101      - remove "-pdefault" option: redundant with the use of "packages.conf";
102      - remove file pkg/pkg_default : set the default as a pkg group
103        ("default_pkg_list") defined in pkg/pkg_groups;
104      - fix for case pkg/pkg_depend is missing (was hanging before);
105      - add option "-pgroups" to specify a different pkg_groups than the default.
106    o verification/adjustment.cs-32x32x1:
107       add a "minimal" set-up test (code_min & input_min) which only compiles
108       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
109    o tools/genmake2
110      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
111      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
112    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
113      files are nearly the same anyway.
114      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
115       - redefinition of tau(i,i) (by a factor of ustar)
116       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
117       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
118       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
119       - replace
120         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
121         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
122         by
123         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
124         (changes results)
125       -> exf_bulkformulae v1.22,
126          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
127          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
128                    output.txt 1.63
129           offline_exf_seaice: output.seaicetd.txt 1.7
130           seaice_obcs: output.txt 1.10)
131      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
132       -> exf_bulkformulae v1.23,
133          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
134          and global_ocean.cs32x15.icedyn (only 11 matching digits)
135      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
136    o adjoint of exch-1:
137     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
138       (note: was already like this when using EXCH-2) and remove flow dir
139       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
140     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
141     - update pkg/exch2 diff list.
142    
143    checkpoint62g (2010/05/19)
144    o eesupp/src (exch-1):
145     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
146       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
147       (renamed to exch1_*rx_cube.F).
148     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
149       to call new exch1 S/R ; update Makefile and .cvsignore.
150     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
151       exch2_xy_rx later)
152      Note: after updating your code, need to run "make clean" in eesupp/src
153    o test experiment bottom_ctrl_5x5:
154       new output_adm.txt with fewer grdchk & less monitor output.
155    o model/src:
156      remove the call to ini_cori in initialise_varia.F (just keep the usual one
157       in initialise_fixed.F). More consistent with coriolis & horizontal grid
158       beeing treated in the same way (ini_grid is not called a 2nd time).
159    o pkg/exf:
160      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
161      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
162      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
163      - cosmetic changes to exf_bulkformulae.F to make it look more like
164        exf_bulk_largeyeager04.F
165    o eesupp/src (exch-1):
166      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
167      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
168        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
169        (even without using MPI).
170      - Message mode: move RecvAck setting (indicator of buffer being ready)
171        from send_put to recv_get S/R (was useless before, but not sure if
172        it's much more useful now);
173      - Switch the order of sync: MPI-proc 1rst and then threads;
174      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
175      - fix AD code for communication mode ='get' (but not used).
176    o model/src:
177      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
178      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
179    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
180    o pkg/ctrl: require a specific set of control variables and exf-flags for
181      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
182    o model/src:
183     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
184       1rst forward sweep, to avoid over-writing output files during recomputations
185       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
186     b) 2nd version:
187      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
188      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
189         writePickupAtEnd) + seaice & ptracers output;
190      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
191    o model/src:
192      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
193    o pkg/exch2:
194      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
195      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
196    o pkg/autodiff & exch2:
197      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
198      (for now, only if ALLOW_EXCH2 is defined).
199    o pkg/autodiff:
200      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
201        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
202       + clean-up comments (_RS is not always real*4)
203      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
204      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
205        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
206    o testreport (AD-tests):
207      no longer link files from dir "../input" (1rst link files from
208      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
209    
210    checkpoint62f (2010/04/29)
211    o model/src/the_main_loop.F:
212      adjust store directives for seaice evp and multicategory according to
213      pkg/ecco/the_main_loop.F
214    o adjoint:
215      global_sum_ad was incomplete (noted many times by many people ;)
216      nice description by Jean U. as follows:
217      * allreduce(var) in global_sum.F can be interpreted as
218        reduce(sum) followed by broadcast of sum.
219      * The adjoint of that is
220        sum(adjoint) followed by broadcast(summed adjoint value)
221        or in other words, allreduce(sum, adjoint vars)
222      We were missing the sum(adjoint)!
223      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
224      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
225      The fix should produce 16-digit accuracy between
226      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
227      multi-CPU single-tile (e.g. nSx=1, nPx-2)
228      We'll probably change this yet again shortly
229    o eesupp/src:
230      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
231    o pkg/icefront
232      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
233        specification of addmass array based on a 2D field, which is added
234        at bottommost wet level at each horizontal location.
235    o model/src:
236     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
237     layout; (not always compatible with delX,delY setting; commented out for now).
238    o pkg/exch2:
239     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
240     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
241    
242    checkpoint62e (2010/04/15)
243    o pkg/obcs:
244      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
245    o pkg/dic:
246      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
247        (note: not presently tested in any forward verification exp.)
248       update tutorial_global_oce_biogeo AD output file.
249    o pkg/exf:
250      - account for the variation of albedo as a function of zenith angle
251        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
252    o build_options:
253     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
254    o pkg/dic:
255      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
256      - use binary pickup file for restart;
257      - initialise atmos-CO2 box from dic_pCO2 parameter;
258      - fix multi-threaded.
259    o pkg/rbcs:
260     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
261       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
262     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
263       and update output.txt
264    o pkg/kpp:
265     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
266     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
267       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
268       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
269     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
270       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
271    o pkg/offline:
272      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
273      (bug was added in version 1.10 on 2007-08-23).
274    o pkg/offline:
275      - no need to specify periodicExternalForcing, etc ... to use offline pack
276      - offline input files no longer just single prec --> parameter offlineLoadPrec
277    o verification/lab_sea:
278      change AD test to multi-tile setup and update all 4 AD output.
279      NOTE: while cost function values remain very similar,
280      gradients are very different, although gradient checks are self-consistent
281      Should try to get to the bottom of this (cost function summation order?)
282    o pkg/dic:
283      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
284      a weakness of TAF that drops part of double precision in log10 derivative.
285      <= changes removed since problem has been fixed in current TAF version 1.9.71
286      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
287    o pkg/ecco:
288      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
289      update all 4 lab_sea AD output.
290    
291    checkpoint62d (2010/03/22)
292    o build_options:
293      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
294    o remove unbalanced quote (single or double) in commented line of source code
295      (may cause some warning with some preprocessor/makedepend versions).
296    o pkg/seaice:
297      fix seaice_model.F for adjoint (gael) and update AD results of experiments
298       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
299    o testreport:
300      add option '-runonly' (short: '-ro') to just do the run part (without make).
301    o eesupp: remove JAM communication code (obsolete).
302    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
303      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
304      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
305      (update also the output).
306    
307    checkpoint62c (2010/03/02)
308    o tools/build_options :
309       move (some) old optfiles from build_options/ to build_options/unsupported/
310    o model/src and pkg/exf
311       surface relaxation -- separating data and data.exf options
312       The point is to ensure that we specify the surface relaxation
313       either in data or in data.exf (but not half and half) and to
314       avoid an accidental relaxation to 0 (which happened if a time
315       scale was specified but the file name was left empty)
316    o model/src model/inc and pkg/mom_common
317       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
318       => addition to the viscosity field as computed by others schemes
319    o tools/build_options:
320      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
321        but keep the former optfile for few weeks for smooth transition
322    o pkg/ecco
323      - allow user defined cost function contributions
324            CPP: ALLOW_USERCOST_CONTRIBUTION
325            USAGE: compute contributions in cost_usercost_all.F
326      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
327          the two options are complementary.
328    o pkg/smooth
329      - migration from contrib to the main repository
330    
331    checkpoint62b (2010/01/26)
332    o pkg/monitor:
333      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
334        (in case someone forgot to update customized pieces of code)
335    o nonHydrostatic:
336      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
337      - add a simple 2-D experiment (short_surf_wave) to test it.
338    o pkg/icefront:
339       adding the shell of, and the hooks to, a new package that
340       will model melting and freezing of vertical glacier ice fronts
341    o momentum:
342      add diagnostics of momentum tendency from Hydrostatic pressure gradient
343       (without surf.pressure term: would need a 2nd filling since implicit term).
344    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
345      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
346      cannot deal with the former
347    o cleaning:
348      - remove all (except OpenAD) old TLM output from results_ad dirs.
349      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
350      - comment out maskH definition (replaced by maskInC)
351    o pkg/monitor:
352      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
353        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.

356    o model/src:
357      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
358    o pkg/diagnostics:
359      - add optional level number diagnostics (i.e., level number to be define
360        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
361      - strictly check for valid parser-code(10) ;
362      - check if adding diag to the list from the right place.
363  o pkg/longstep:  o pkg/longstep:
364    - change parameters and fix tracer conservation with rstar/nonlinear free surface    - change parameters and fix tracer conservation with rstar/nonlinear free surface
