4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      - seaice_preconditioner:
9        + replace one remaining press by pressLoc (mistake)
10        + adjust printing of residuals
11      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
12        + add (SEAICE.h) and rename some counters (initiliased in
13          seaice_init_fixed.F)
14        + add _BEGIN/END_MASTER (myThid)  around print statements
15        + print total number of iterations and failures over SEAICE_monFreq
16          interval to STDOUT
17      - move control over output-messages by fgmres to seaice_jfnk to save
18        some operations
19      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
20        in order to make restarts with sol .ne. zero (fgmres with restarts)
21        (seaice_jfnk.F, seaice_fgmres.F)
22      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
23        a serious convergence problem when open boundaries are involved
24    o pkg/ggl90: fix computation of control volumes for the case of
25      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
26      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
27    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
28    o pkg/autodiff
29      - Add inAdMode switch for SEAICEuseDYNAMICS:
30        SEAICEuseDYNAMICSinAdMode
31        (extend logic in ADAUTODIFF_INADMODE_SET)
32    o pkg/seaice
33      - Step 1 of merging ice-thickness distribution (ITD) code from
34        MITgcm_contrib/torge/itd/ (author: Torge Martin)
35        The code implements concept laid out in Thorndike et al. (1975);
36        code is enabled via CPP flag SEAICE_ITD
37        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
38        code is not complete yet!!
39      - SEAICE_SIZE.h now included in almost all seaice routines
40    o verification (using seaice):
41      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
42        global_ocean.cs32x15.seaice ; update results.
43      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
44      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
45        offline_exf_seaice (previously compiling B-grid).
46    o pkg/exf:
47      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
48        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
49        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
50    o pkg/layers (adjust changes from Sept 19):
51      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
52        this allows to remove "layers_maxNum" dimension from all layers arrays.
53    o pkg/layers (adjust changes from Sept 19):
54      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
55      - snap-shot extended to all type of layers (not just the 1rst type);
56      - remove layers variables when corresponding CPP option is undef.
57    o pkg/layers:
58      - rename pkg/layers variable and add new output (layer exist & un-weighted
59        velocity in layer)
60    o pkg/seaice:
61      - simplify (?) ocean-drag coefficent computations by using
62        the same routine in all three solvers (saves some code lines)
63      - remove global fields DRAGA and DRAGS from C-grid code and
64        declare them locally in lsr.F (the only place where they are
65        still used)
66      - update AD output of lab_sea.evp (very sensitive anyway).
67    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
68      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
69      and SEAICEuseJFNK=.true. A few things to note:
70      - involves a FGMRES, that is parallel but very inefficient,
71        because of many scalar products (global sums) in the Gram-Schmidt
72        orthogonalization method. Needs to be replaced. Original code
73        from J.-F. Lemieux
74      - preconditioner for FGMRES is a stripped down version of LSOR
75      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
76        preconditioner. For the preconditioner, the default is set to 10.
77      - Jacobian times vector is computed with finite differences
78      - marginally related to JFNK-solver: add a smooth regularization for
79        zeta with tanh that will improve convergence (Lemieux and Tremblay,
80        2009) for any implicit solver (not implemented for EVP because EVP
81        does not need this regularization in the first place). Define
82        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
83    o eesupp/src:
84      - check in genmake2 that intrinsic S/R flush is available.
85      - add S/R to flush IO unit (if intrinsic S/R flush is available)
86      - flush standard & error msg unit before MPI termination
87      - if debugMode, flush IO unit after printing msg
88    o pkg/ctrl:
89      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
90        to ctrl_set_unpack_xyz.
91    
92    checkpoint64 (2012/10/09)
93    o pkg/shelfice
94      - in mom_fluxform.F, mom_vecinv.F:
95        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
96        Bug fix KappaRU -> KappaRV
97        does not change verification/isomip but may change other setups
98        (presumably constant KappaRU=KappaRV)
99      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
100    o pkg/obcs:
101      - fixed some indexing bugs in obcs_seaice_sponge.F
102      - added obcs relaxation subroutines for HSALT and HSNOW
103      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
104    o pkg/seaice:
105      - add "multicategory" parameterization for snow in analogy to ice,
106        default is off for now.
107    o pkg/obcs:
108      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
109        see verification/seaice_obcs/input.seaiceSponge for example application.
110      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
111        index setting by master-thread. This fix multi-threads Pb in previous modifs.
112    o pkg/layers :
113      - add diagnostics to pkg/layers
114      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
115        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
116    o pkg/generic_advdiff/gad_implicit_r.F :
117      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
118    o pkg/seaice/seaice_growth.F:
119      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
120    o pkg/obcs:
121      - change default setting of OBCS_UVICE_OLD from defined to undef;
122      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
123        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
124      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
125      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
126        with Southern & Western OB at a tile edge (at least in a simple set-up).
127    o pkg/obcs:
128      - change settings of OB index in case OB coincides with tile edge (shared by
129        2 tiles), so that common OB location is registered by both tiles (instead of
130        only 1). However, for Southern and Western OB, index value = 0 is not
131        recognized as valid OB index (=default null value) and needs to be fixed.
132      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
133      - new parameter "OB_indexNone" for null index value (for now, still zero)
134        to replace hard-coded null index value of zero.
135    o pkg/exch2:
136      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
137        always check buffer-size (but outside the loop); move checking for valid
138        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
139        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
140    o pkg/ctrl (pack & unpack):
141      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
142        (locally defined) for different variables (+ remove the variable-specific
143        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
144        (to be extended to other local file names in ctrl.h).
145    o pkg/flt:
146      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
147    o pkg/mdsio:
148      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
149    o tools/genmake2:
150      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
151        (added by Alistair in version 1.51 for building without make depend);
152      - remove Header files list (H_SRC_FILES) from the dependence of targets
153         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
154        place in version 1.23): this save going through staf when unrelated header
155        file has been modified.
156       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
157        "make depend" step, still need to do "make links" before "make adtaf".
158    o eesupp/src (+ few pkg src files) & genmake2:
159      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
160      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
161      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
162         upper/lower case ; account for space between "#" and undef/define)
163    o pkg/flt (with exch2):
164      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
165      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
166    
167    checkpoint63s (2012/09/05)
168    o pkg/ecco:
169      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
170      - add more relevant #ifdef ALLOW_SMOOTH ones.
171      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
172    o pkg/ctrl:
173      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
174        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
175      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
176        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
177        ctrlSmoothCorrel3D (new).
178        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
179      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
180      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
181        controls when useAtmWind, and vice versa.
182      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
183      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
184          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
185      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
186          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
187      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
188        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
189    o pkg/smooth:
190      - remove un-necessary includes.
191      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
192        Those CPP options were never defined, and not necessary.
193    o model/src:
194      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
195      - standard treatment of useSMOOTH.
196    o pkg/autodiff:
197      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
198        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
199    o pkg/exch2:
200      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
201        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
202      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
203        and tiles to process mapping.
204      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
205        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
206        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
207        from w2_eeboot.F to w2_readparms.F.
208    o eesupp/src:
209      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
210        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
211        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
212      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
213        is defined (remove condition on usingMPI) to match cases where MPI_INIT
214        has been called.
215      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
216      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
217        (so that on 1 proc, get same myPid independently of usingMPI)
218      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
219        useCubedSphereExchange with EXCH-1 (safer).
220      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
221    o pkg/ggl90:
222      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
223        used in ALLOW_GGL90_SMOOTH code.
224    o pkg/flt:
225      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
226        floats at the Southern end of the domain).
227    o eesupp/inc:
228      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
229        but not used (and not to be used) anywhere, just for documentation.
230    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
231      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
232        a) can damage previously written records in any other multi-record files.
233        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
234    o tools/genmake2:
235      - define variable MAKE within Makefile and use it in place of 'make';
236      - update AD_CONFIG.h (if needed) before building any of the executable
237        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
238        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
239      - always print usual warning comment 'this file is automatically generated'
240        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
241    o pkg/cheapaml:
242      - updated to correspond to the code used in accepted paper (Nico Wienders).
243    o pkg/exf:
244        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
245        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
246        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
247    o pkg/exf, autodiff, ctrl, ecco and seaice:
248        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
249    o pkg/ctrl, ecco:
250        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
251        Depending on useAtmWind, one is inactive, and the other is active (see
252        exf_getffields.F/exf_getsurfacefluxes.F).
253    o tools/genmake2:
254      - improve error msg when failing in 2nd test of check_for_broken_Ff
255      - fix option '-makefile' short-name (-mf according to genmake2 -help)
256      - source local config file "genmake_local" just after processing the genmake2
257        command arguments (previously done before processing arg).
258    o pkg/grdchk:
259      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
260        to this routine from cost_final has been dropped in g_cost_final)
261      - improve printed information (more explicit msg, no longer using "print *,"
262         fix fcpertminus printed value).
263    o model/src:
264      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
265        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
266        this prevents getting cost-funct reset in adinitialise_varia recomputations.
267    o pkg/dic:
268      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
269        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
270    o pkg/grdchk:
271      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
272      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
273    o pkg/autodiff/ctrl/grdchk :
274      - attempt to sort out what works and what does not,
275        with regard to I/O, and to warn/stop accordingly.
276    o pkg/grdchk:
277      - attempt to fix grdchk in the case of useSingleCpuIO.
278      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
279       statements were moved from grdchk_main.F and into
280       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
281      - a global sum is applied to record numbers icvrec/layer
282       out of grdchk_loc so that they be passed to I/O routines.
283    o pkg/smooth:
284      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
285        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
286    o verification/testreport:
287      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
288      - can also use compressed (gzip) reference output file;
289      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
290        to be easier to collect by testreport.
291      - update existing TLM output (half out-of-date by more than 3 yrs).
292      - report NETCDF & LAPACK settings (from genmake2) in output dir.
293      - report run-time in each individual summary (previously only for AD test);
294        for TLM test, add also TAF version.
295      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
296    
297    checkpoint63r (2012/08/15)
298    o tools/genmake2:
299      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
300    o pkg/ecco/ecco_cost_final.F :
301      - fix fc print statements (to stdout and costfunction0000) so
302        that the printed value is always after the global sum.
303    o pkg/seaice/seaice_dynsolver.F :
304      - fix ice strength assymptote at SEAICE_area_max<1
305        (no change for the standard case of SEAICE_area_max=1)
306    o some cleaning:
307      - pkg source files: ensure that all *.F files from each pkg included the
308        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
309        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
310        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
311        includes;
312      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
313      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
314        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
315        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
316      - update option-file CPP_OPTIONS.h of all AD experiments:
317        * no longer include PACKAGES_CONFIG.h ;
318        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
319        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
320          including ECCO_CPPOPTIONS.h).
321    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
322      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
323        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
324        not necessary accurate).
325      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
326        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
327        deliberately break compilation (a remainder that it needs to be customized)
328      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
329      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h

332      - check for lapack.
333    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
334      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
335        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
336        from both packages.
337      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
338      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
339      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
340        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
341    o pkg/cost : add comments to explain special and/or untested setups.
342  o pkg/exf:  o pkg/exf:
343    - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h    - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
344      (previously, ALLOW_AUTODIFF_TAMC was controling this switch).      (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
