4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/thsice:
8      - vectorize thsice_solve4temp and thsice_get_exf.
9        Problem: thsice_solve4temp has an unvectorizable statement that
10        might also be problematic for TAF
11      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
12        does not change the verifcation experiment, but will change all
13        experiments that have this flag undefined (not tested in verification);
14        a little reorganization to save a few 2D fields and recomputations
15    o pkg/obcs: add support for exch2
16      - the position of the boundary and prescribed values are specified using
17        a global domain with exch2 facets stacked
18        - in x for N,S boundaries (like W2_mapIO=-1)
19        - in y for E,W boundaries (so E,W boundaries do not overlap)
20    o pkg/mdsio: add support for writing global sections with exch2
21        file layout is as for obcs described above:
22        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
23        - for y-z sections, facets are stacked in y
24    o pkg/thsice:
25       - change a few routines for better vectorization: thsice_albedo.F,
26         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
27         not affected, but in particular the latter routine has changed
28         dramatically (not necessarily easier to read now).
29       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
30       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
31    o verification/lab_sea:
32      - overhaul of the forward model experiments. The main motivation
33        for this revision is that lab_sea has proven quite fragile (when
34        changing the sea-ice code, and switching platforms) to a point
35        when failures were very hard to attribute to specific code problems.
36      - the suspected reason for this fragility is noise amplification by evp so,
37        to start with, we decided to replace evp with lsr in the main experiment.
38      - the input.lsr experiment thus became obsolete and was removed.
39      - it was replaced with the input.fd experiment that uses an
40        analytical "free drift" solution as the ice velocity field.
41      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
42        will hopefully allow us to discriminate problems due to dynamic solvers
43        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
44        us to test additional options, along with the salt plume package.
45      - Finally a pickup was generated (at the end of a one year run) to
46        make the tests more representative of an actual model run. Previously
47        the tests starting point was a 1m thickness of ice everywhere.
48    o pkg/seaice:
49      - introducing S\R seaice_freedrift.F that compute the
50        analytical solution to an approximate ice momentum
51        equation (i.e. the simple stress/coriolis balance).
52      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
53        of the free drift velocity field, and enable its use.
54        To actually use the free drift solution as the model ice
55        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
56    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
57    
58    checkpoint62l (2010/10/04)
59    o pkg/seaice:
60      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
61      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
62       version (with USE_ORIGINAL_SBI undef);
63    o add hooks for new packages OASIS, the package will follow
64      (hooks exclude the seaice pkg for now)
65    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
66      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
67      rather than mdsio_readvector.F/mdsio_writevector.F, within
68      adread_adwrite.F to read/write adjoint-related tapes to disk.
69    o eesupp and pkg/mdsio: ALLOW_WHIO
70      Option to write/read 2D fields to files including tiles halos.
71      The main purpose is for adjoint related "tape I/O".
72      The secondary purpose is for debugging phases.
73      A word on those rather specifically intended purposes.
74      The code was meant to be stripped down to the bare minimum.
75      Typically, there is a unique and basic mapping to the global
76      buffer (tile by tile, then proc by proc, then level by level), and
77      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
78      meant to generate user friendly outputs of various shapes and forms.
79      Rather it is intended, for the knowledgeabale developers,
80      to be largely independent of the many mdsio options, to allow
81      outputs of tiles+halos in debugging phases and in adjoint runs,
82      and to allow some flexibility in tuning (adoint) I/O depending on each
83      file system behavior. With regard to tuning, most of the potential knobs
84      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
85      to specify directories, to specify the typical size of I/O calls, etc.)
86      are not yet included, and will be added if they prove useful.
87    o pkg/seaice:
88       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
89    o pkg/seaice:
90       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
91       code (seaice_budget_ice_if.F) which enable to recover old standard
92       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
93       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
94    o model/src (rStar):
95       use simple average (not area weighted) of rStarFac at U,V point when using
96       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
97       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
98    
99    checkpoint62k (2010/09/17)
100    o adjoint
101       * changed verification/global_ocean.cs32x15 ; adjoint now tests
102         Adams-Bashforth 3 + NLFS + RSTAR
103       * some more modifs required for ECCO-GODAE v4
104    o pkg/seaice
105       add SEAICE_AGE_VOL option to use volume instead of area for
106       integrating SEAICE_AGE
107    o model/src:
108       first check-in of sigma & hybrid-sigma coordinate code ; also includes
109       non-linear free-surface parts ; but pressure-gradient not yet coded.
110    o pkg/ptracers:
111       option for ptracer to convert Salt Relax into additional EmP.
112        tested in exp. global_ocean.90x40x15.dwnslp (update output)
113    
114    checkpoint62j (2010/08/25)
115    o pkg/ggl90:
116       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
117    o pkg/dic: car_flux.F, phos_flux.F
118      - reduce number of exp-calls in order to improve performance
119      - clean up a little (replace fields by their macros, etc., fix
120        typo in CPP-flag)
121    o pkg/ggl90: minor changes
122      - GGL90diffKrS was removed --> always use GGL90diffKr
123      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
124      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
125        (commented out for now)
126      - change in max/min operations to ensure that smoothing is ok
127      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
128      - always use diffKrNrT as background profile (i.e. never use diffKr field)
129    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
130    o pkg/dic:
131      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
132        vectorization
133      - small bug fix in insol for the unlikely case of a cartesian grid
134      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
135        + now vectorize, which also removes adjoint recomputations;
136        + replace integer maksp1 by _RL maskp1
137        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
138    
139    checkpoint62i (2010/07/21)
140    o pkg/flt:
141      - with OBCS: stop floats which enter the OB region
142    o model/src:
143      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
144        for implicit vertical advection.
145    o pkg/seaice:
146     - account for melting in seaice age evolution.
147     - remove double counting of seaice ridging effect on seaice age.
148    
149    checkpoint62h (2010/06/18)
150    o pkg/exch2:
151     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
152    o tools/genmake2
153      - remove "-pdefault" option: redundant with the use of "packages.conf";
154      - remove file pkg/pkg_default : set the default as a pkg group
155        ("default_pkg_list") defined in pkg/pkg_groups;
156      - fix for case pkg/pkg_depend is missing (was hanging before);
157      - add option "-pgroups" to specify a different pkg_groups than the default.
158    o verification/adjustment.cs-32x32x1:
159       add a "minimal" set-up test (code_min & input_min) which only compiles
160       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
161    o tools/genmake2
162      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
163      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
164    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
165      files are nearly the same anyway.
166      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
167       - redefinition of tau(i,i) (by a factor of ustar)
168       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
169       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
170       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
171       - replace
172         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
173         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
174         by
175         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
176         (changes results)
177       -> exf_bulkformulae v1.22,
178          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
179          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
180                    output.txt 1.63
181           offline_exf_seaice: output.seaicetd.txt 1.7
182           seaice_obcs: output.txt 1.10)
183      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
184       -> exf_bulkformulae v1.23,
185          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
186          and global_ocean.cs32x15.icedyn (only 11 matching digits)
187      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
188    o adjoint of exch-1:
189     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
190       (note: was already like this when using EXCH-2) and remove flow dir
191       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
192     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
193     - update pkg/exch2 diff list.
194    
195    checkpoint62g (2010/05/19)
196    o eesupp/src (exch-1):
197     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
198       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
199       (renamed to exch1_*rx_cube.F).
200     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
201       to call new exch1 S/R ; update Makefile and .cvsignore.
202     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
203       exch2_xy_rx later)
204      Note: after updating your code, need to run "make clean" in eesupp/src
205    o test experiment bottom_ctrl_5x5:
206       new output_adm.txt with fewer grdchk & less monitor output.
207    o model/src:
208      remove the call to ini_cori in initialise_varia.F (just keep the usual one
209       in initialise_fixed.F). More consistent with coriolis & horizontal grid
210       beeing treated in the same way (ini_grid is not called a 2nd time).
211    o pkg/exf:
212      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
213      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
214      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
215      - cosmetic changes to exf_bulkformulae.F to make it look more like
216        exf_bulk_largeyeager04.F
217    o eesupp/src (exch-1):
218      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
219      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
220        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
221        (even without using MPI).
222      - Message mode: move RecvAck setting (indicator of buffer being ready)
223        from send_put to recv_get S/R (was useless before, but not sure if
224        it's much more useful now);
225      - Switch the order of sync: MPI-proc 1rst and then threads;
226      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
227      - fix AD code for communication mode ='get' (but not used).
228    o model/src:
229      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
230      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
231    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
232    o pkg/ctrl: require a specific set of control variables and exf-flags for
233      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
234    o model/src:
235     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
236       1rst forward sweep, to avoid over-writing output files during recomputations
237       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
238     b) 2nd version:
239      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
240      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
241         writePickupAtEnd) + seaice & ptracers output;
242      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
243    o model/src:
244      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
245    o pkg/exch2:
246      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
247      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
248    o pkg/autodiff & exch2:
249      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
250      (for now, only if ALLOW_EXCH2 is defined).
251    o pkg/autodiff:
252      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
253        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
254       + clean-up comments (_RS is not always real*4)
255      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
256      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
257        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
258    o testreport (AD-tests):
259      no longer link files from dir "../input" (1rst link files from
260      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
261    
262    checkpoint62f (2010/04/29)
263    o model/src/the_main_loop.F:
264      adjust store directives for seaice evp and multicategory according to
265      pkg/ecco/the_main_loop.F
266    o adjoint:
267      global_sum_ad was incomplete (noted many times by many people ;)
268      nice description by Jean U. as follows:
269      * allreduce(var) in global_sum.F can be interpreted as
270        reduce(sum) followed by broadcast of sum.
271      * The adjoint of that is
272        sum(adjoint) followed by broadcast(summed adjoint value)
273        or in other words, allreduce(sum, adjoint vars)
274      We were missing the sum(adjoint)!
275      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
276      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
277      The fix should produce 16-digit accuracy between
278      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
279      multi-CPU single-tile (e.g. nSx=1, nPx-2)
280      We'll probably change this yet again shortly
281    o eesupp/src:
282      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
283    o pkg/icefront
284      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
285        specification of addmass array based on a 2D field, which is added
286        at bottommost wet level at each horizontal location.
287    o model/src:
288     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
289     layout; (not always compatible with delX,delY setting; commented out for now).
290    o pkg/exch2:
291     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
292     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
293    
294    checkpoint62e (2010/04/15)
295    o pkg/obcs:
296      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
297    o pkg/dic:
298      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
299        (note: not presently tested in any forward verification exp.)
300       update tutorial_global_oce_biogeo AD output file.
301    o pkg/exf:
302      - account for the variation of albedo as a function of zenith angle
303        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
304    o build_options:
305     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
306    o pkg/dic:
307      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
308      - use binary pickup file for restart;
309      - initialise atmos-CO2 box from dic_pCO2 parameter;
310      - fix multi-threaded.
311    o pkg/rbcs:
312     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
313       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
314     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
315       and update output.txt
316    o pkg/kpp:
317     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
318     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
319       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
320       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
321     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
322       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
323    o pkg/offline:
324      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
325      (bug was added in version 1.10 on 2007-08-23).
326    o pkg/offline:
327      - no need to specify periodicExternalForcing, etc ... to use offline pack
328      - offline input files no longer just single prec --> parameter offlineLoadPrec
329    o verification/lab_sea:
330      change AD test to multi-tile setup and update all 4 AD output.
331      NOTE: while cost function values remain very similar,
332      gradients are very different, although gradient checks are self-consistent
333      Should try to get to the bottom of this (cost function summation order?)
334    o pkg/dic:
335      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
336      a weakness of TAF that drops part of double precision in log10 derivative.
337      <= changes removed since problem has been fixed in current TAF version 1.9.71
338      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
339    o pkg/ecco:
340      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
341      update all 4 lab_sea AD output.

344    o build_options:
345      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
346    o remove unbalanced quote (single or double) in commented line of source code
347      (may cause some warning with some preprocessor/makedepend versions).
348    o pkg/seaice:
349      fix seaice_model.F for adjoint (gael) and update AD results of experiments
350       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
351    o testreport:
352      add option '-runonly' (short: '-ro') to just do the run part (without make).
353    o eesupp: remove JAM communication code (obsolete).
354    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
355      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
356      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
357      (update also the output).

361       move (some) old optfiles from build_options/ to build_options/unsupported/
362    o model/src and pkg/exf
363       surface relaxation -- separating data and data.exf options
364       The point is to ensure that we specify the surface relaxation
365       either in data or in data.exf (but not half and half) and to
366       avoid an accidental relaxation to 0 (which happened if a time
367       scale was specified but the file name was left empty)
368    o model/src model/inc and pkg/mom_common
369       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
370       => addition to the viscosity field as computed by others schemes
371    o tools/build_options:
372      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
373        but keep the former optfile for few weeks for smooth transition
374  o pkg/ecco  o pkg/ecco
