4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs:
8      - change OBCSfixTopo default from True to False (should not change the results);
9        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
10    o pkg/thsice:
11      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
12        2nd layer seaice sublimation (unlikely to happen)
13      - use Interior mask for OBCS in thsice_advection.F (similar to what is
14        done in gad_advection & seaice_advection).
15    o adjoint:
16      bug fix spotted by Gael Forget:
17      seaice_advection and thsice_advection still had
18      legacy CPP options to avoid CS corner updates for adjoint
19    o pkg/seaice:
20      => Change some of the defaults (2011/05/29):
21         - change SEAICEuseFluxForm default (from False to True)
22         - change DIFF1 default (from 0.004 m/s to 0. m/s)
23         And print warnings if DIFF1 is not set in data.seaice and centered
24          avection scheme is used without any diffusion.
25      also:
26      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
27      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
28      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
29        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
30        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
31      update results of test exp.:
32         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
33             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
34             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
35         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
36         seaice_obcs: output (SEAICEuseFluxForm=T)
37      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
38          for standard fwd & AD lab_sea tests (to keep the same output).
39    o pkg/seaice/seaice_growth.F:
40      - use Ian Fenty's capping formulas for actual ice
41      thickness thoughout EVOLUTION branch.
42      - put treatment pathological case #2) in CPP brackets
43      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
44      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
45    o pkg/seaice:
46      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
47      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
48      also pass fac as a param, which can be 1. (to update the tendency
49      field) or the time step (to update the field itself).
50      - seaice_advdiff.F: for multidim, call seaice_diffusion with
51      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
52      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
53      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
54      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
55    o pkg/seaice:
56      diffusion with centered advection scheme (diffus.F & advect.F):
57      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
58        to just compute the laplacian of input-field.
59      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
60      - fix flux-form version in diffus.F to conserve tracer.
61      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
62       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
63    
64    checkpoint62y (2011/05/26)
65    o pkg/seaice:
66     - seaice_growth.F : in EVOLUTION branch, always include
67       a_QSWbyATM_cover in qnet (as it should be).
68     - verification/global_ocean.cs32x15 : update results accordingly
69       (output.seaice.txt output_adm.seaice.txt).
70    o pkg/seaice + obcs:
71     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
72       equivalent of assuming no tracer gradient outside the OB region.
73       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
74     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
75       after changes above);
76     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
77       only at OB location (instead of over a band of OLx width).
78    o pkg/seaice:
79     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
80       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
81    o pkg/obcs:
82      - split header file "OBCS.h" into 4 separated files:
83        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
84       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
85         (contain no conditional statement which depends on OBCS options).
86      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
87        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
88    o ctrl, cost, grdchk & autodiff pkgs:
89      - make options file more standard (like other {PKG}_OPTIONS.h file but
90        with AD_CONFIG.h); clean-up some of the included header files.
91    o pkg/obcs:
92      - do not mask tracer when applying OB (tracer == 0 could generate problems)
93      - apply tracer OB values to tracer field only at OB location (instead of
94        over a band of OLx width)
95      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
96      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
97        obcs_apply_tloc.F & obcs_apply_sloc.F
98    o obcs in model/src:
99      - call OBCS_APPLY_W only if NonHydrostatic.
100      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
101      - reset dEtaHdt and wVel to zero outside OB interior region ;
102      - leave tracer unchanged outside OB interior region: This has no effect
103        on the solution but just to prevent unrealistic tracer value outside OB.
104      - zero out velocity outside OB interior region: This has no effect on
105        the solution but just to prevent unrealistic velocity outside OB.
106    o obcs and non-lin free-surf:
107       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
108       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
109       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
110       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
111       update results of test-exp. exp4(nlfs).
112    o exp4 (nlfs) test-exp:
113       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
114       with NonLin-FreeSurf); update output.nlfs.txt
115    o obcs and 2d/3d solver norm:
116       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
117       and outside OB interior region (will allow to place OB further inside the
118       domain). Depending on the domain, can affects cg2d-Norm (previous
119       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
120       and cg3d-Norm (previous Norm was computed before canceling OB terms),
121       e.g. in tutorial_plume_on_slope.
122      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
123    o pkg rbcs:
124      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
125      - add capability to apply relaxation to horizontal velocity uVel & vVel.
126    o pkg/grdchk: add gradient check for control variable xx_shifwflx
127    o pkg/shelfice/shelfice_init_fixed.F
128      fix CPP-flag combinations
129    o pkg/seaice: Merge iceage code of Pierre Rampal
130      * update/change/correct ice age calculations
131      * add age updates for pathological cases
132      Probably needs more testing...
133    
134    checkpoint62x (2011/05/13)
135    o pkg/mom_vecinv:
136       high-order vorticity scheme: use interior masks (maskInW & S)
137       to zero-out (outside OB) gradient of vorticity.
138    o verification exp.:
139       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
140       hs94.128x64x5 and seaice_obcs ; update results.
141    o pkg/obcs:
142      fix bug in OBeta for YZ sections in obcs_exf_load.F
143    o pkg/ctrl, pkg/shelfice, and optim:
144      - add new control variable xx_shifwflx (fresh water flux underneath ice
145        shelves). This is almost as tedious as obcs-ctrl, because the
146        variables needs its own mask.
147      - add a cost function term that penalizes the deviation of xx_shifwflx
148        from the first guess (zero) in analogy to other control variables
149    o pkg/shelfice:
150      - start basic adjoint
151    o pkg/ctrl:
152      - remove extra 2D field "for good measure" when initializing in
153        ctrl_set_globfld_[xy/xz/yz].F
154      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
155      - improve error messages in ctrl_set_unpack_*
156    o OBC implementation in momentum:
157       use interior masks (maskInC,W & S) in momentum S/R:
158       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
159       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
160       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
161       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
162       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
163        (and also with Leith/Smagorinsky harmonic-viscosity).
164       Update output of experiment dome and exp4 (+nlfs).
165    o exp4 test-exp:
166      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
167        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
168        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
169        time-varying OB at Western-side for wVel (NonHyd); update output.
170      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
171        and biharmonic-viscosity ; also use prescribed time varying OB.
172    o pkg/obcs:
173      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
174    o model/src:
175      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
176      - initialise startTime & nIter0 with unlikely values: allows to set one
177        from the other without ambiguity.
178    o seaice_obcs test-exp.:
179      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
180    o pkg/obcs:
181      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
182        no longer needed with maskInC,W,S in pkg/generic_advdiff.
183    o pkg/seaice:
184      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
185        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
186      - fixed bug in the initialization of sea ice salinity variable HSALT
187        in seaice_init_varia.F  (removed dependence on ICE2WATR)
188    o fizhi-cs test exp.:
189       switch reference output convention for these 2 non-standard test-exp,
190        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
191          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
192       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
193    o model/inc:
194      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
195        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
196    o pkg/seaice:
197      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
198    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
199      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
200        and initial HSALT
201    
202    checkpoint62w (2011/04/26)
203    o pkg/mom_fluxform:
204      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
205      - use parameter "sideDragFactor" in no-slip BC side-drag part.
206      - update output of exp. global_ocean.90x40x15
207    o pkg/mom_vecinv:
208      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
209    o update seaice exp.:
210      use more consistent parameter values (remove "backward compatability only":
211       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
212      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
213       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
214    o update test-exp global_ocean.90x40x15:
215      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
216      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
217      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
218      o turn on zStar & viscA4 in standard set-up (dir input/)
219        and update output files: output.txt & output.dwnslp.txt
220    o new AD-test experiment: obcs_ctrl
221      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
222    o pkg/dic:
223      fix two bugs in handling water vapour pressure in carbonate chemistry
224      and air-sea fluxes. Found by Val Bennington and Galen McKinley
225      (add DIC Option = WATERVAP_BUG to recover old results)
226      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
227    o adding allowInteriorFreezing option to check for water below freezing point
228      at depth and bring the negative heat anomaly to the surface level
229    o pkgs _fields_load:
230      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
231      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
232        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
233        rbcs to get interpolation weights and time reccord number.
234      - fix multi-threading in aim_fields_load.F
235      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
236    o external_fields_load:
237      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
238       interpolation weights) to use in a periodic time-series ; do not divide by
239       time-step to convert to integer:
240       - this fixes case where externForcingPeriod is not multiple of time-step
241          (Thanks to Christopher L. Wolfe)
242       - this fixes case where externForcingPeriod is an odd multiple of time-step
243         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
244      store index of time-record which is currently loaded:
245       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
246       - needed for the adjoint but not yet used because of extensive recomputations;
247         (to be fixed soon)
248    
249    checkpoint62v (2011/04/02)
250    o verification/1D_ocean_ice_column added to test Ian Fenty's
251      pkg/seaice_growth.F modifications for improving sea ice code differentiability
252    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
253      (new velocity statistics after changing maskInW & maskInS definition)
254    o pkg/generic_advdiff with OBCS:
255      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
256      equivalent to assumption of no tracer gradient outside the OB region.
257      This will affect the results if using obcs+biharmonic diffusion.
258      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
259    o pkg/obcs:
260      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
261      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
262      in Interior region. No impact on solution but affects Velocity monitor stats.
263    o pkg/ptracers (adjoint)
264      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
265      tape file for each tracer
266    o model/inc/src and pkg/autodiff: add parameters that allow to turn
267      of parts of the adjoint code at run time. For now, there are only
268      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
269      parameters are set in data.pkg.
270      This is the lazy coward's version of doing this, but still useful for
271      debugging. In order to do it right, everything needs to be moved to
272      pkg/autodiff.
273    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
274      the end; this fixes the adjoint balancing code for open boundaries.
275    o pkg/ctrl:
276      - change behavior of xx_${varname}period to be analogous to exf-conventions:
277        xx_${varname}period =   0.,  means time-independent control part
278        xx_${varname}period = -12., means one-year-periodic monthly control part
279      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
280        clean up ctrl_init a little, remove unused variables
281      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
282      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
283    
284    checkpoint62u (2011/03/15)
285    o model/src:
286      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
287        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
288      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
289        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
290    o pkg/ctrl/obcs/ecco:
291      - remove obsolete, unused, and partially broken code:
292        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
293        ALLOW_CTRL_OBCS_BALANCE
294      - put a stop statement into ecco/cost_obcsvol.F, but also add
295        cost_obcsvol to ecco_ad_diff.list
296    o pkg/ecco: fix counting cost function contributions for obcs (code
297      by Matt M.) and diffkr for diagnostics
298    o pkg/ecco, pkg/ctrl, pkg/grdchk:
299      add cost penalty terms for initial uvel, vvel, eta controls
300      and I/O for prior error files
301    o pkg/mdsio:
302       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
303       (new argument) to check for tiled file in mdsioLocalDir : this fix the
304       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
305    o pkg/ctrl:
306     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
307       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
308       unused and superfluous variables
309     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
310    o pkg/ecco
311     - enable adjoint of Stevens OB
312    o pkg/ctrl/ecco/grdchk:
313      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
314        Fortunately, we do not have any tests for the numerous cpp-flagged
315        option of "obcs as control parameters" so we will never know
316        if this is an improvement (but at least now things compile).
317      - remove an obsolete initialization from ecco_cost_init_barfiles.F
318      - fix some problems within never used ifdefs to make the code compile
319    o pkg/obcs:
320     - Refine Interior mask definition to work with more complex OB (e.g.
321       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
322       read in Interior mask from file. Check if Interior mask is consistent
323       with OB list of indices.
324    o pkg/seaice
325     - beginning code for a seaice tracer package,
326       but currently only used for seaice age: SEAICE_AGE
327       SEAICE_num = 4
328       iTracer = 1: area-weighted ice age
329               = 2: volume-weighted ice age
330               = 3, 4: template for one-year vs. multi-year ice
331       data.seaice has new namelist SEAICE_PARM03 for arrays related to
332       SEAICE_num
333    
334    checkpoint62t (2011/03/05)
335    o pkg/obcs:
336     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
337       then normal component. This ensures that the normal component is set
338       correctly even when it conficts with tangential setting from an other OB.
339       Affects results of test-experiment seaice_obcs: update the output.txt
340    o pkg/obcs:
341     - add code to monitor statistics of dynamical fields at OB.
342     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
343       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
344       - change default: balance the Net inflow through all OB (instead of balancing
345         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
346     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
347       to match Nortern OB inflow (OBCS_balanceFacN=0).
348    o pkg/seaice:
349     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
350    o pkg/seaice (seaice_growth v 1.113):
351     - reverting seaice_growth to v 1.111 in order to have code with exact bit
352       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
353       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
354       runtime flag SEAICEareaFormula is kept but is inactive
355    o model/src:
356     - add new param to scale curvilinear grid distance and area when using
357       a different sphere radius from the grid-files.
358     - test/check multi-threads EXCH applied to local variable (cg2d_x)
359    o adjoint:
360     - enable adjoint of Stevens OB
361     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
362       (a bit delicate because of potentially modified adj. common block structure;
363       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
364    
365    checkpoint62s (2011/02/15)
366    o pkg/seaice (seaice_growth v 1.112):
367     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
368       computing the ice cover tendency from effective thickness tendencies. Include
369       Ian Fenty's formula.
370     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
371       SEAICEareaFormula.
372     - simplify notations for the various d_HEFF/d_AREA terms.
373    o pkg/gmredi:
374     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
375       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
376       add a verification test-run (front_relax.bvp) to test GM_useBVP.
377    o pkg/seaice (seaice_growth v 1.111):
378     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
379     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
380       also melt ice.
381    o pkg/seaice:
382     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
383     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
384    o pkg/cheapaml:
385     - from Nico Wienders: New version of this package.
386    o pkg/flt:
387     - add CPP options to prevent floats to re-enter the opposite side of
388       a periodic domain (default: keep periodicity)
389    o pkg/gmredi:
390     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
391       (needed for multi-dim advection).
392     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
393    o model/src:
394     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
395    o tutorial_tracer_adjsens
396     - extend to NLFS and replace maskC by hFacC
397       (change reference output accordingly)
398    
399    checkpoint62r (2011/01/24)
400    o testreport:
401     - add option -deloutp (-do) to remove output file after successful run
402     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
403       extract exact list of procs from this file ; adjust COMMAND by
404       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
405    o pkg/ecco: replace old ineffective way of penalizing deviations from
406      first guess (of obcs) with code by Matt Mazloff
407    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
408      exf/cal
409      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
410        and handle case of obcs?period == 0
411        Not affected by these changes: There is still an inconsistency in
412        the computation of start/endrec for the obcs variables for ALLOW_CAL
413        defined (see comment by Menemenlis, 7-Mar-2003)
414      - make S/R ctrl_get_gen_rec return something meaningful even if
415        ALLOW_CAL is not defined
416      - ctrl_getobcs?: simplify code so that it does not need to use
417                       S/R exf_swapfields
418    o testreport:
419       allow to test MPI with different number of processors for each experiment:
420       create file "SIZE.h.mpi" in each build dir.
421       Note: update of "-command" argument not yet implemented.
422    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
423      alleviate the need for additional 3D tapes when using
424      the non-inear free surface in the adjoint. This is done
425      by adding an 'update' of hfacc etc. to their current
426      value at the beginning of forward_step.F.
427    o pkg/seaice
428      seaice_lsr: move stress-divergence computations out of outer pseudo-
429      timestepping loop
430    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
431      up, so that the calls of the ctrl_* subroutines are really at the end
432      of the routine.
433    o pkg/gmredi:
434      allow to specify a 2-D horizontal map and a 1-D vertical profil
435      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
436    o pkg/seaice:
437      move lsr iterations from seaice_dynsolver to seaice_lsr.
438    o pkg/seaice:
439      reduce memory footprint of seaice mutldim advection tapes,
440      by using a 2D tape independent of the generic_advdiff ones,
441      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
442    
443    checkpoint62q (2010/12/29)
444    o model/src:
445      - check horizontal grid-spacing for unset or zero/negative values.
446      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
447    o pkg/flt:
448      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
449      - precision of input and output files set according to readBinaryPrec
450        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
451      - initial float position from tiled file was not converted to index space
452        (looks like a bug): fixed to make it similar to initial pos. global file.
453    o global_ocean.cs32x15:
454       change SIZE.h of AD set-up to get same tiling as with MPI.
455       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
456    o model/src:
457       add flag to control printing of domain fields (bathymetry, hFac ...) in
458       ini_mask_etc (call to plot_fieds_xy*).
459    o pkg/thsice:
460       if useEXF, some forcing fields are not valid in overlap: fixed by computing
461       over the interior only + apply EXCH at the end (like with SEAICE advection).
462    o pkg/mdsio:
463      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
464        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
465      - change barrier call for safe multi-threads access to 3-D shared buffer.
466      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
467      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
468        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
469    o pkg/flt:
470      - add fourth-order Runge-Kutta integration
471      - add basic exch2 support (only 1 facet supported so far!)
472    o pkg/mdsio+rw:
473      new S/R to read local (or tile independent) vector (read counterpart of
474       mds_writevec_loc, and front-end write_glvec_rl/rs).
475    o global_ocean.cs32x15: additional input_ad.seaice experiment
476        that uses pkg/seaice rather than pkg/thsice.
477        (using multidim advection for seaice)
478    o towards more F95 syntax for array specification in namelist:
479      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
480        of all verification experiments.
481           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
482          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
483      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
484    o global_ocean.cs32x15: additional input.seaice experiment
485        that uses pkg/seaice rather than pkg/thsice.
486    
487    checkpoint62p (2010/12/17)
488    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
489        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
490    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
491        allow for use of multim. advection in seaice adjoint.
492    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
493      - first attempt to close budgets by taking into account the freshwater
494        flux implied by the sublimation of snow and ice. So far only the
495        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
496        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
497    o eesupp/src:
498      new S/R with new option (NML_EXTENDED_F77) to change array specification
499      from F95 standard to commonly accepted extended F77 form.
500      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
501      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
502      for less tolerant f77 compiler (e.g., pgf77, g77).
503    o globalFiles:
504      commented out in parameter file "data" since it's not safe with MPI
505      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
506      in this case); no longer commented out in restart test (tst_2+2).
507    o add adTapeDir to specify a special directory where adjoint tapes are
508      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
509      and cannot be used together with mdsioLocalDir.
510    o nesting pkgs:
511      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
512      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
513      - add parameter files + utils dir + output from short run on beagle.
514    o pkg/seaice:
515        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
516    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
517      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
518    
519    checkpoint62o (2010/11/25)
520    o pkg/exf:
521      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
522    o pkg/seaice:
523      - seaice_ocean_stress: split a loop for better vectorization of the
524        adjoint code
525      - seaice_growth.F: fix bug in conservation of freshwater connected to
526        capping of heff, put contribution into d_HEFFbyNEG
527      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
528        by something more sensible (parameters that are what their name implies)
529      - change some defaults, so that by default exf-parameters are used for
530        things like rhoAir, cpAir,latent/sensible heat parameters, in order
531        to reproduce the old results, many data.seaice now contain funny values
532        for cpAir and latent heat of sublimation
533    o packages_readparms.F: move exf_readparms up in line so that
534        exf-parameters are visible for other packages (e.g. seaice)
535    o debugMode & debugLevel=2:
536      - differentiate between debugMode & debugLevel=2:
537        debugMode: controls printing of debug messages (sequence of S/R calls).
538        debugLevel: controls printing of algorithm intermediate results and stats.
539      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
540        => allows to print debug-stats without all sequence of call messages.
541      - switch control of debug print from debugLevel to debugMode in many S/R.
542    o pkg/obcs (obcs-sponge):
543        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
544        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
545    o pkg/generic_advdiff:
546      - record overlap minimum size for each advection scheme;
547      - refine criteria on overlap minimum size;
548      - check and stop (in gad_check) if overlap size is too small.
549    o pkg/obcs:
550      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
551        once, in ptracers_implicit.F)
552      - with seaice: remove test on empty file name in obcs_apply_seaice (always
553        apply OB values when tile has OB)
554    o model/src, coriolis setting:
555      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
556        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
557        files (selectCoriMap=3) with any grid.
558      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
559    o pkg/seaice/seaice_growth.F:
560        a few cosmetic changes that reduce the number of lines of code
561    o pkg/obcs: add boundary conditions following Stevens (1990)
562      - the code follows old MOM/NAOSIM code
563      - so far it is only implemented for the eastern and western boundaries
564        and NOT for pTracers
565    o pkg/rbcs:
566      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
567        beginning of the first rbcs forcing period.
568      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
569        offline package, i.e., one file per time, labeled by iteration number;
570        deltaTrbcs sets the timestep with which the data was generated;
571        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
572      - rbcsForcingCycle=0 makes forcing non-cyclic.
573      - make arithmetic safe for negative times and odd forcing periods.
574    
575    checkpoint62n (2010/11/09)
576    o pkg/seaice:
577        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
578    o pkg/obcs:
579       New S/R to copy tracer value from the OB location to narrow band region
580        (width = same as overlap) beyond the OB: preserve OB value (needed for
581        high-order scheme) which were overwritten by EXCH call if in overlap
582        region. Applied to theta, salt, ptracer and advected seaice variables.
583       With seaice: use maskInC in similar way as in gad_advection.F,
584        in seaice_advection.F and advect.F.
585       Update output of experiment seaice_obcs and change exp4 to test OBCS with
586        4th order Adv.Scheme. for pasive salt and ptracer.
587    o tools/genmake2:
588      - when looking for an optfile (not specified), only search for Fortran compiler
589        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
590      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
591        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
592      - set default for CPP to "cpp -traditional -P" (was the case without specifying
593        an optfile, but otherwise default was just "cpp".
594      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
595      - when "CC" is not set in the optfile, look for possible C compiler
596        (instead of just setting CC=cc)
597      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
598        => add a ".F" to ".o" rule for source files with no "#include" (such as
599           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
600      - move gfortran before g77 in list of possible Fortran compiler (consistent
601        with reference compiler switch from g77 to gfortran)
602    o pkg/seaice:
603      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
604        seaice_check that stops the model, when the CPP flag is used.
605      o seaice_growth.F: make capping of ice volume conserving by returning the
606        capped ice as freshwater to EmPmR. This does not change the verification
607        experiments but will change runs where the capping is acutally active
608    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
609      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
610         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
611         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
612    o tools/genmake2:
613      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
614      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
615      - clean previous genmake log files before anything else.
616      - change Makefile to remove testreport log files (*.tr_log) and genmake log
617        files only with "CLEAN" target (instead of "Clean");
618    o pkg/generic_advdiff:
619      Change OBCS in multiDim advection (gad_advection.F):
620       Use maskInC to prevent intermediate update of tracer-field in OB regions,
621       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
622       which were applying future time-step OB values.
623      This way, all explicit calculations use current-time-step OB values
624       (simpler and more consistent).
625      Affects results when set-up uses time-varying OBC and multi-dim advection;
626       update output of experiment seaice_obcs.
627    o pkg/seaice:
628      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
629       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
630         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
631      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
632       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
633       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
634    o pkg aim (2010/10/26):
635      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
636        formulation with obliquity, eccentricity, ... as run-time parameters,
637      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
638        upward shortwave radition at the surface (all-sky and clear-sky).
639    o pkg/obcs:
640      - writing sections with globalFiles=T does not work: switch to tiled-files
641        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
642      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
643      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
644    
645    checkpoint62m (2010/10/21)
646    o pkg/seaice: vectorize seaice_solve4temp.F
647      - move iterations loops outside of i/j-loops
648      - requires 2D arrays for TB and effConduct
649      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
650        modified in this routine
651      - a little bit of clean up, adjusting indentation, etc.
652      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
653        performance and '**TWO' by '**2' (because TWO is a float),
654        replaced ONE, ZERO
655  o eesupp/src:  o eesupp/src:
