4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - move bi,bj loops inside INTEGR_CONTINUITY ;
9      - call INTEGR_CONTINUITY directly from forward_step.F
10        (previously called from momentum_correction_step.F)
11      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
12        forward_step.F and pkg/ecco/the_main_loop.F
13    o model/src/do_oceanic_phys.F:
14      - reset addMass to zero only if useICEFRONT ;
15      - separated k-loop for rhoInSitu calculation ;
16      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
17        and at constant T,S (= WdRHOdP);
18      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
19        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
20        transport of locally-referenced potential density);
21        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
22    o gluemnc:
23      - replace ncrcat with ncks when adding variables to *.glob.nc
24      - change the way variables without record dimensions are handled so that
25        files that have variables with and without record variables can be glued:
26        add a record dimension with a new unique name to be able to differentiate
27        between variable with and without a-prior record dimensions. Remove
28        this record dimension before adding the variable to the *.glob.nc file.
29        This procedure automatically works also for grid.*.nc files that do not
30        have any record dimension.
31    o verification/cpl_aim+ocn:
32      - generate new reference output on baudelaire (gfortran, mpich2) (previously
33        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
34    o pkg/obcs/obcs_calc_stevens.F:
35      - add code for northern and southern boundaries.
36      - reorder some loops to save some operations and so that drFBar can be scalar
37    o model/src:
38      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
39        truncation) and add diagnostics for Adams-Bashforth tendency increment.
40      - update test-exp. AD output:
41        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
42      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
43        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
44        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
45        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
46        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
47        tutorial_plume_on_slope.
48    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
49      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
50      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
51      does not even come with an F77 compiler anymore, this should not be
52      a limitation
53    
54    checkpoint63e (2011/11/06)
55    o pkg/seaice adjoint of LSR:
56      - substantially rework STORE dirs.
57      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
58        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
59        and only perform SOLV_MAX_FIXED adjoint iters.
60        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
61        always goes to same record, meaning that the last forward field will be
62        the one used in the adjoint - an approximation.
63      - now produces non-zero LSR-related gradients, and acceptable gradients for
64        An's zonal (x-z) test case (to be checked in)
65      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
66        (but these are screwed up by the thermodynamics in the first place);
67        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
68        output_adm.txt also reflects changes to seaice_lsr
69      - global_ocean.cs32x15:
70        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
71          (output_adm.seaice.txt was updated)
72        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
73          (output_adm.seaice_dynmix.txt)
74    o test-exp. exp4+stevens:
75      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
76    o pkg/seaice (lsr solver):
77      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
78        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
79      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
80      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
81        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
82      - compute (with new S/R) and print initial (+ free-driff sol. if available)
83        and final residual of linearised system.
84    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
85      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
86    o pkg/obcs: Stevens BCs (still only for east and west)
87      - fix Stevens BCs by using intermediate velocities of previous
88        time step as "baroclinic" contribution rather velocity of one grid cell
89        inside the boundaries; more consistent but makes the entire treatment
90        more complicated, requires new pickup files and two new S/Rs:
91        obcs_copy_uv_n and obcs_save_uv_n
92        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
93        (undefined by default)
94      - silently move computation of some grid factors into separate loops to
95        save some recomputations
96      - add a hack for non-linear free surface
97      - add a verification experiment to exp4 that tests this code
98    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
99    
100    checkpoint63d (2011/10/25)
101    o pkg/obcs + seaice-dynamics:
102      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
103        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
104        values (consistent with an implicit method).
105      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
106        return to older implementation (same results as before); note that none of
107        the "experimental" OBCS_SEAICE options are implemented in the new version.
108      - switch test exp. seaice_obcs to use new version (update output).
109    o pkg/seaice:
110      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
111      - add parenthesis in Water-Ice drag calculations (evp & lsr);
112      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
113        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
114      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
115        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
116    o pkg/layers:
117      - Include potential density as new coordinate (Thanks to David Munday)
118    o pkg/dic:
119      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
120        carbonate computation/output to CALC_PCO2_APPROX
121    o pkg/generic_advdiff
122      - make TAF generate code that vectorizes:
123        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
124    o model/src:
125      - improve vectorization also for adjoint code of
126        solve_tridiagonal and solve_pentadiagonal. As this requires up to
127        5 new 3D-fields, this code is only turned on for the combination of
128        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
129        for singular matrix check (only for TARGET_NEC_SX).
130      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
131        ALLOW_AUTODIFF. This flag now needs to be set outside of
132        solve_tri/pentadiagonal.F
133    o pkg/exf:
134      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
135        optional namelist EXF_NML_OBCS).
136      - add many debug-print (to trace down where pkg/cal error msg comes from)
137    o pkg/mom_vecinv/mom_vi_hdissip.F
138      - rearrange loops so that vectorization is improved and in particular
139        the adjoint routine vectorizes. The code is a little longer now, but I
140        think easier to read.
141        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
142    o pkg/seaice:
143      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
144    o pkg/exch2:
145      - alternative code (without tile x tile matrix) for cumulated (global) sum;
146        used as default; keep using matrix version in adjustment.cs-32x32x1.
147    o tools/build_options:
148      - after merging some MPI and/or multi-threads specific optfiles so that
149        the modified default optfile support both built (using genmake2 -mpi
150        for the MPI built, using genmake2 -omp for OpenMP built),
151        move now obsolete optfiles to tools/build_options/unsupported/
152       (add copy of email sent to support list in doc/optfiles_changes.txt)
153    
154    checkpoint63c (2011/09/28)
155    o pkg/ebm:
156      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
157        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
158    o pkg/seaice (SItracer pickup)
159    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
160      To be done:
161      - thorough testing of missing fields in S/R seaice_read_pickup
162      - thorough matching between generic tracers and specific fields used
163        (e.g. volume-weighted age, area-weighted age, salinity, ...)
164    o pkg/grdchk:
165      - all procs calculate and print finite-difference gradient (for testreport)
166      - change description output used by testreport;
167      - AD testing: also compare and report Finite-difference gradient;
168        => update all output_adm*.txt
169    o test exp. global_ocean_ebm:
170      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
171        and turn on exactConserve; update (fwd) output.
172    o pkg/seaice (LSR):
173      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
174      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
175        * identical results with non-CS topology (but save up to half of EXCH calls)
176        * no much changes in cs-32 verification tests since no ice at face edges
177         (differences due to convergence criteria, since nb of iterations changed)
178        * expect some differences on lat-lon-cap grid.
179        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
180    o pkg/exch2:
181      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
182        many tiles); until alternative coding is added, just add a stop.
183    o pkg/kpp:
184      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
185        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
186    o optfiles:
187      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
188        into corresponding standard one, which now support different build:
189        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
190      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
191    o pkg/obcs (seaice):
192      - add missing EXCH for uIce,vIce after applying OBCS;
193      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
194        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
195        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
196      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
197      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
198        and eedata.mth for MPI and mutlti-threaded testing.
199    o pkg/flt:
200      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
201      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
202      - fix pickup and trajectories + profiles output with multi-threads;
203      - add parameter to select group of fields to write along trajectory and
204        profile (default unchanged);
205      - only call PORT_RAND* function when flt_noise <> 0;
206      - add multi-threaded test for verification exp. flt_example.
207    o eesupp/src:
208      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
209      - USE_OMP_THREADING: check that number of threads (from eedata) matches
210        actual number (from env.var. setting).
211    o pkg/ebm:
212      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
213      - add multi-threaded test for verification exp. global_ocean_ebm
214    
215    checkpoint63b (2011/08/29)
216    o pkg/ebm:
217      - fix sign of runoff;
218      - update directly forcing fields (Qnet,EmPmR) to use standard
219        external_forcing_surf.F (remove ebm_forcing_surf.F);
220      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
221      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
222        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
223      - update global_ocean_ebm parameters file data and update output (fwd+ad).
224    o verification/matrix_example:
225      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
226        MPI and mutlti-threaded testing.
227    o pkg/matrix:
228      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
229      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
230      - fix for multi-threaded (remove DATA statement);
231      - use standard DIFFERENT_MULTIPLE function;
232      - add MATRIX_OPTIONS.h
233    o verification/matrix_example:
234       To allow to split the domain in several tiles, change the domain size
235        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
236        Western side) of land points.
237    o (*_)write_pickup:
238      - fix few bugs in mypackage_read/write_pickup.F
239      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
240        array of length 1 (was caught by compiler syntax-check).
241    o pkg/diagnostics (velocity potential solver):
242      - fix initialisation of main diagonal matrix (for overlap values)
243    o tools/build_options:
244      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
245        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
246      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
247        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
248        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
249        and use "-devel" testreport option for standard testing on baudelaire.
250    o pkg/grdchk:
251      - Assume that all gradient-check position are within the same tile
252        corresponding to global indices (iGloTile,jGloTile) and that
253        positions (i,j indices or nbeg) are local to this tile;
254      - set tile local-indices and proc. number according to tile global-indices;
255      - remove grdchkwhichproc from namelist (retired param);
256      - send adjoint gradient to all procs so that all procs print it to STDOUT;
257      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
258    o adding package bbl (Bottom Boundary Layer)
259      description in MITgcm/pkg/bbl/bbl_description.tex
260      example/test experiment in MITgcm_contrib/bbl
261    o adjoint verifications
262      - changed 5 experiments to multi-tiles
263        * global_ocean.90x40x15
264        * obcs_ctrl
265        * offline_exf_seaice
266        * tutorial_dic_adjoffline
267        * tutorial_tracer_adjsens
268        changed reference output for those that crossed tile boundaries
269        (changed choices of gradient check positions)
270      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
271      - temporary bug fix in grdchk_loc.F for obcs
272    o genmake2 & testreport
273      - add target "obj" (just for OBJFILES files) to Makefile;
274      - add option to specify FEXTRAFLAGS on command line.
275    o pkg/mypackage:
276      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
277    
278    checkpoint63a (2011/08/02)
279    o pkg/diagnostics (velocity potential):
280      - fix velocity-potential calculation when using OBCS: balance net inflow
281        at each level (new S/R OBCS_DIAG_BALANCE).
282      - fix some of the problems with OBCS in stream-function calculation.
283    o pkg/exf/exf_readparms.F
284      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
285        EXF_NML_OBCS) more consistent, so that you need not have these lists
286        in data.exf when they are not used.
287    o optim/optim_readdata.F:
288      - add some output about obcs variables that might help debugging
289      - add a check about nvarlength
290    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
291    o pkg/diagnostics (velocity potential):
292      - fix mask for OBCS (still problems in stream-function with OBCS);
293      - add specific parameter (default = main code CG2D params) for solver;
294      - in case of poor convergence, use solution corresponding to lowest residual.
295    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
296      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
297      and should be avoided where possible.
298    o model/src (rStar):
299      - include r* effect on reference-state (PhiRef) in totPhiHyd
300        (so that it's really the potential anomaly at the cell center);
301        affect solution only if z* with full pressure in EOS.
302      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
303        update output (because of z* in totPhiHyd and viscA4 changes);
304      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
305        @ constant r) until interpolation at constant r is implemented.
306    o pkg/diagnostics
307      - fix RCENTER diagnostics in case cell center is not at interface middle
308    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
309      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
310      that THETA and SALT are "conservative temperature" and "absolute
311      salinity"
312    o pkg/ctrl
313      - fix computation of endrec in s/r ctrl_init_rec
314      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
315    o pkg/seaice/seaice_growth.F
316      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
317        remove then obsolete STORE directives
318      - fix STORE directives for tice and tices, so that only the
319        appropriate part of the fields are stored (and not the entire
320        field); update global_ocean.cs32x15.seaice AD output.
321      - cosmetic changes: adjust CPP flags and indentation for better
322        legibilty
323    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
324      Chris Wilson)
325    o pkg/gmredi:
326       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
327       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
328    
329    checkpoint63  (2011/07/11)
330    o pkg/exch2:
331     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
332     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
333       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
334       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
335    o pkg/diagnostics:
336     - deal with pairs of post-processed diags which are computed together; in
337       particular, re-order list of diags within 1 file to save 2nd computation.
338     - add S/R to compute velocity stream-function (called after velocity-potential
339       calculation) from divergence free transport -> new diagnostics "PsiVEL".
340     - add parameter to select grid-point location where PsiVEL == 0.
341    o eesupp/src:
342       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
343       (specific S/R needed with exch2 topology - for now, just print an error msg)
344    o pkg/shelfice
345     - Implement friction velocity-dependent transfer coefficients following
346       Holland and Jenkins, JPO, 1999
347       Original code by M. Losch with small modifs.
348       Enable with CPP option SHI_ALLOW_GAMMAFRICT
349       and runtime flag SHELFICEuseGammaFrict
350    o verification lab_sea & global_ocean.cs32x15:
351     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
352       does not miss some dependencies (but is slower) and also works with many files
353       (default makedepend limitation for AD built).
354     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
355    o pkg/diagnostics:
356     - add run-time parameter "useMissingValue" (def=False) to fill land-point
357        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
358       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
359     - Extend the use of "missing_value" setting from data.diagnostics for the case
360       of counter-diagnostics (where fraction-weight is zero). This applies both to
361       MNC and MDS output files.
362    o pkg/seaice/seaice_growth.F:
363      - add 'a priori' cap of latent heat flux based on actual mass considerations
364        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
365        non-legacy seaice_solve4temp.
366      - add diagnostic of the residual sublimation freshwater flux (the freshwater
367        flux taken from the ocean if the total actual latent heat fluxes exceed
368        the maximum)
369      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
370       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
371      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
372       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
373      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
374      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
375    o verification 1D_ocean_ice_column:
376       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
377       update results
378    o pkg/diagnostics:
379     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
380       which are not filled-up but computed from other diags ; In this case, the mate
381       diag points to the primary (filled-up) diag to used for post processing.
382     - Update Velocity-potential computation using post-processed diag framework.
383     ==> Change the ordering of fields and time-periods in MDS output file
384       when using periodic averaging: now writes one time record with the full set
385       of fields for this time period, then the next time reccord (it used to be
386       one field with the full set of time records then the next field).
387         Note: this is now similar to NetCDF (MNC) output file. <==
