4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
8                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
9      - requires an additional time level that is stored in the pickup
10      - you can start with AB2 from a pickup without this time level with
11        pickupStrictlyMatch = .false.
12    
13    checkpoint64h (2013/05/26)
14    o pkg/cheapaml:
15      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
16        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
17      - consistent treatment of uWind,vWind location: assume everywhere in
18        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
19        (Note: was already the case for Tair,Qair advection);
20        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
21      - compute diabatic forcing only in the interior (excluding overlap regions)
22      - fill in array "Qsw" (for short-wave heating);
23      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
24        before any update (consistent with MITgcm state var diagnostics);
25      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
26        non periodic ; + adjusted for uWind,vWind (C-grid).
27    o pkg/seaice:
28      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
29        add explicitly pkg/exf in experiments that currently use pkg/seaice.
30      - allows to compile pkg/seaice without pkg/exf.
31    o tools/OAD_support:
32      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
33        of array "ourStepOf" in function rvNextAction (revolve.F90).
34    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
35      - change pkg name (to be used with other atmospheric physics pkg)
36        but by-pass CVS when making the new pkg so that we keep the CVS history.
37    o pkg/offline:
38      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
39        (previously called from pkg/dic_surfforcing_init.F)
40    o model/src:
41      - re-order sequence of calls within packages_init_variables.F, using
42        standard order, except for:
43         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
44         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
45    o new pkg: atm_phys
46      - add entry point and source code (previously in contrib
47          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
48        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
49      - re-order sequence of calls within packages_readparms.F,
50         packages_init_fixed.F and packages_write_pickup.F
51        (but skip packages_init_variables.F because of TAF issues).
52      - update contrib/*/atm_gray/ experiment.
53    o pkg/seaice (ITD code):
54      - simplify and fix the writing of pickup-files for ITD case
55    o pkg/seaice (ITD code):
56      - introduce floe size dependent lateral melt for ITD case;
57      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
58      - update seaice_itd experiment main output.
59    o pkg/thsice:
60      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
61        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
62        changed accordingly pkg/atm2d.
63    
64    checkpoint64g (2013/05/01)
65    o pkg/exf ALLOW_RUNOFTEMP
66      - if defined,  river and glacier runoff temperature can be read-in from
67        runoftempfile; runoftempfile needs to have same format as runofffile
68    o pkg/thsice (& pkg/bulk_force):
69      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
70        for energy content of Precip + RunOff & Evap (like with pkg/exf).
71      - change computation domain to always be the interior (without overlap).
72      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
73    o verification/tutorial_global_oce_biogeo:
74      - add preliminary OpenAD setup (still has problems)
75    o pkg/seaice:
76      - turn some parameters for choosing the convergence criterion of
77        the inexact Newton method (JFNK) into runtime parameters for convenience
78      - clean up seaice_calc_viscosities.F: remove/retire two options for
79        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
80        the results of lab_sea/input because a division has been replaced by
81        a multiplication with the reciprocal (sumNorm)
82      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
83        convergence of solver (changes results, of course), and to test some
84        new features
85    o model/src:
86      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
87      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
88      - move forcing adjustment (balancing surface forcing) in specific S/R
89        where might also be applied exchanges (if needed) to forcing arrays.
90    o pkg/shelfice:
91      - allow to specify the Ice-Shelf mass per unit area (instead of
92        shelficeLoadAnomaly) and do the conversion from one to the other
93      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
94        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
95        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
96        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
97      - update isomip experiment forward output (get machine truncation error
98        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
99    o verification/offline_exf_seaice:
100      revise data.seaice in input.thermo and input_ad and update results accordingly
101        HO = 0.2, SEAICE_areaLossFormula = 2,
102        SEAICE_growMeltByConv = .TRUE.,
103        SEAICE_doOpenWaterMelt = .TRUE.,
104      Improve consistency with input.thsice and fix the spurious 500m ice corners
105    o verification/global_ocean.cs32x15:
106      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
107        in icedyn (thsice+seaice-dyn) test and update output.
108    o verification/offline_exf_seaice:
109      - adjust list of tested variables (with testreport) and update
110        standard test output with better slection of monitored fields.
111    o pkg/cd_code:
112      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
113        experiment lab_sea.hb87
114    o tools/genmake2:
115      - change default makedepend from the system default to tools/xmakedepend:
116        When no makedepend is specified, select tools/xmakedepend it the test pass,
117        otherwise select the system default (if exist and pass the test) or
118        try to build cyrus-makedepend ; stop if none of the 3 works.
119    o pkg/exf & pkg/thsice:
120      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
121        for energy content of Precip + RunOff & Evap. Assumes:
122       1) Rain has same temp as Air.
123       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
124       3) Run-Off comes at the temp of surface water (with same Cp)
125       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
126        put directly into Latent Heat flux & should use water-vapor heat capacity.
127       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
128        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
129    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
130        (compile when SEAICE_ALLOW_JFNK is defined)
131    o pkg/thsice:
132      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
133        implementation): move THSICE_AVE call after the advection (called directly
134        from thsice_do_advect.F).
135    o verification/global_ocean.90x40x15 and OpenAD:
136      New experiment for OpenAD is identical to the one in input_ad except that
137        multiDimAdvection=.FALSE.,
138      There is still an issue with this.
139    o pkg/thsice:
140      - account for ice velocity (ocean relative velocity) in turbulent heat flux
141        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
142        and offline_exf_seaice (main test).
143    
144    checkpoint64f (2013/03/31)
145    o verification/OpenAD:
146      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
147    o verification/isomip, pkg/shelfice and OpenAD:
148      - add OpenAD setup to this exp and make shelfice package work with OpenAD
149    o verification/tutorial_global_oce_biogeo:
150      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
151    o verification/offline_exf_seaice:
152      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
153    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
154      - add OpenAD setup to this exp and make ptracers package work with OpenAD
155    o pkg/seaice/seaice_evp.F:
156       mask the asymmetric contribution of the ice-ocean stress (when
157       the turningAngle is non-zero) over open water to avoid stripes
158       in the EVP-solutions after many EVP-substeps. This does not change
159       the verification experiment (because turningAngle=0 in that experiment),
160       but will affect other EVP solutions with turningAngle.ne.0
161    o verification, AD & TLM output:
162      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
163        additions and multiplications which affect results at machine truncation
164        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
165        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
166        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
167        digits of matching.
168    o pkg/seaice:
169       modify lsr-algorithm so that it vectorizes AND converges by using a
170       "zebra" method: split vector loop into two with step size 2; this
171       solves a general convergence problem for the JFNK solver on a vector
172       computer. It has the potential to even improve convergence for
173       non-vector machines, but it does change the results so it is turned
174       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
175       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
176    
177    checkpoint64e (2013/03/05)
178    o pkg/ecco and several verification experiments:
179       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
180       from ecco package, and revert to unified routine in model/src/
181       Adjust verification experiments accordingly, especially gloal_oce_llc90
182       Should conclude long-standing work by Gael to reconsile the_main_loop with
183       ECCO and will enable OpenAD's revolve loop in ECCO setup.
184    o pkg/generic_advdiff:
185      - implement compressible flow method for multi-dim advection (similar to
186        gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since
187        TAF generates many recomputations) to use it; no yet coded with implicit
188        vertical advection.
189      - change experiment advect_cs (new output) and advect_xy (same output)
190        to test compressible flow multi-dim advection.
191    o pkg/generic_advdiff:
192      - fix SOM advection for unusual cases (linear Free-Surf in r*, other
193        cases where linear Free-Surf is not @ k=1, e.g., useShelfIce)
194    o pkg/seaice:
195      - fix bug in the no-slip implementation in seaice_calc_strainrates.F, this
196        bug affects two verification experiments (lab_sea and lab_sea.hb87),
197        recover old (wrong) results by setting noSlipFac = 2. in
198        seaice_calc_strainrates.F;
199      - add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0
200      - add runtime parameter SEAICE_JFNKepsilon for that finite difference
201        gradient in the Jacobian times vector operation (s/r seaice_jacvec)
202      - fix line search in seaice_jfnk.F (s/r seaice_jfnk_update)
203    o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code:
204      - new subroutines seaice_lsr_tridiagu/v
205      - introduce loop bounds i/jmin/max to be able to use a restricted
206        additive Schwarz method, but not used for now.
207      - rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS
208      - use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner
209    o OpenAD support
210       Reorganize S/R call for overall time-stepping loop to facilitate
211       OpenAD revolve loop replacement
212       (new S/R main_do_loop.F)
213    o model/src:
214      - add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3;
215      - pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R
216        ADAMS_BASHFORTH2.
217    o pkg/cheapaml:
218      - add new parameter (default=F, same as before) to disable full domain
219        (including land) periodicity in X & Y dir.
220      - new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of
221        prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer
222        into single S/R CHEAPAML_TIMESTEP.
223    
224    checkpoint64d (2013/02/17)
225    o pkg/monitor (angular momentum):
226      - do not add Eta contribution to the total AM if using rigid-lid;
227      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
228      - horizontal discretisation: compute Zonal wind contribution separately for
229        each component (instead of from cell centered averaged) and use the 4
230        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
231      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
232        FreeSurf) if using vectorInvariant momentum.
233    o model/src (horizontal grid):
234      - move initialisation of all horizontal grid arrays to null value
235        from specific horizontal grid S/R to main S/R INI_GRID;
236      - add 2 new arrays to project model C-grid velocity on to zonal direction
237        (similar to AngleCosC & -AngleSinC but at U and V point location) and
238        compute them in S/R CALC_GRID_ANGLES.
239    o pkg/seaice: replace a hard coded parameter by a runtime parameter
240        SEAICE_JFNK_tolIter
241    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
242        preconditioner for JFNK (run LSR into the overlaps as far as possible,
243        i.e OLx/y-2, but overwrite the solution in the overlaps)
244      - extend loop range in seaice_calc_viscosity
245      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
246      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
247      - slightly modify loops in tridiagonal solver lsr-preconditioner
248      - by default remove the extra exchange in seaice_preconditioner with a
249        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
250      - modify offline_exf_seaice so that old results without RAS are reproduced
251        for output.dyn_jfnk.txt
252      in seaice_fgmres.F (unrelated to RAS)
253      - add a cpp-flag option for a re-ordered mapping (potentially more
254        efficient), but because this changes the results, turn it off by
255        default
256      - replace the save statement by local common blocks
257    o utils/matlab:
258      - fix tile-offset in rdmnc.m when output was produced using EXCH2.
259      - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
260        instead of local script "load_cs.m".
261    o pkg/seaice:
262      - fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected
263        to the scalarProductMetric and the unrolling. By chance this does not
264        change the verification experiment, because of the particular domain
265        decomposition
266    o pkg/diagnostics:
267      - change default missing_value from UNSET_RL to -999.
268    o pkg/layers: improve vectorization of layers_fluxcalc.F
269      - step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu
270        time spent in this routine by more than a factor of 3 on an NEC-SX8
271      - step 2: replace search algorithm by a bisection algorithm found in
272        Press et al. Numerical Recipes in Fortran. This algorithm can be
273        vectorized and finds the correct bin in approx. log2(Nlayers) steps.
274        For now, use this algorithm only for TARGET_NEC_SX defined.
275      - moved the search algorithm into a separate subroutine, that is kept
276        within the same file for automatic inlining.
277      - modified catching potential errors
278    o pkg/ecco:
279      - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY.
280    o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk :
281      - modifications for ALLOW_GENTIM2D_CONTROL
282      -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes.
283      -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid )
284      -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc
285      -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F
286    o model/src:
287      - account for moist thermodynamics in (dry) potential temperature equation;
288        update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev)
289        and cpl_aim+ocn.
290      - also switch to standard compiler (gfortran, was using ifort previously)
291        for fizhi-cs experiments reference output.
292    o pkg/ctrl:
293      - 1st step toward generic time-varying control variable (2D) via CPP option
294        ALLOW_GENTIM2D_CONTROL
295      - note new namelist ctrl_nml_genarr in data.ctrl
296    o verification/global_ocean.cs32x15:
297      - switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new
298        thsice calling sequence and update "output.icedyn.txt" output file.
299    o pkg/ptracers:
300      - from Ryan A.: code to allow to restart a tracer at regular time interval
301        specifying a reset frequency and a reset-phase (for each tracers).
302    o pkg/thsice:
303      - implement new sequence of calls for thsice+seaice:
304          previously:   ice-Dyn,ice-Advect,ice-Thermo(thsice)
305          new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect
306      - allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE"
307        in CPP_OPTIONS.h) to recover old sequence;
308      - update diagnostics for Intermediate State thsice diagnostics: now filled
309        just before advection (instead of just after advection in old sequence);
310      - update output of experiment offline_exf_seaice (standard test);
311      - in global_ocean.cs32x15 exp., postpone output.icedyn.txt update
312        by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h
313    o pkg/aim_v23:
314      - use tiled array for aim_CO2 and surface wind speed for export to coupler;
315      - use standard pkg/mdsio routines to read & write CO2 pickup file;
316      - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F;
317      - Implement new sequence of calls for seaice advection (with thsice and
318        seaice diffusion): do ice advection after ice-Thermodynamic (previously
319        was done before); change aim_do_physics.F (split the bi,bj loops block);
320      - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence;
321    o pkg/thsice:
322      - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case
323        where just seaice diffusion is used without seaice-dynamics.
324    
325    checkpoint64c (2013/01/18)
326    o pkg/seaice:
327      - add a parameter JFNKres_tFac that can replace JFNKres_t
328        (= JFNKres_tFac*JFNKresidual before JFNK solver)
329      - add a line search option to the JFNK solver
330      - move update of u/vIce and computation of initial residual into a separate
331        routine (same file); makes the code a little easier to read (?)
332      - the line search requires computation of the residual and for some reason
333        I cannot do the update of u/vIce at the beginning of the Newton loop
334        without changing the results, so we move computation of the new residual
335        also to the end of the Newton loop, even without the line search
336    o pkg/mdsio:
337      - write missing value (corresponding to undefined array value) to meta files;
338        skip this if missing value is one (UNSET_RL would be a better value for the
339        case of undefined missing value but it's current the default missing-value);
340        Also update mdsio_read_meta.F (reading timeInterval & missing-value).
341    o pkg/exf & thsice:
342      - for diagnostics purpose, fill-up and update Qsw array (+ fill the
343        diagnostics) even when SHORTWAVE_HEATING is #undef;
344    o verification/cfc_example:
345      - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to
346        illustrate how to use it).
347    o verification/offline_exf_seaice:
348      in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing
349        files to only one time-record.
350      in input.thermo: narrow the 2 bands of low initial ice-concentration near
351        N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for
352        snapshot output; same mcPheePiston value as in thsice with
353        surf-current=0.2m/s.
354      in input.thsice: similar set-up as in input.thermo (channel with same seaice
355        initial conditions).
356    o verification/cfc_example:
357      - update file "data" with more standard choice (default rotationPeriod,
358        exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F,
359        set deltaTFreeSurf to deltaTtracer) and update the output.
360    o pkg/layers:
361      - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC;
362      - ensure that "layers_bolus" is switched to False when useGMRedi=False.
363    o verification/offline_exf_seaice:
364      - set all {field}period to zero for constant-in-time forcing (not tested
365        anywhere else).
366    o verification/offline_exf_seaice:
367      - dyn_lsr  : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;
368      - dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice.
369    o model/src:
370      - implement Finite-Volume method for (hydrostatic) presure gradient
371        from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate.
372    o pkg/seaice: implement EVP* by Lemieux et al. (2012).
373      - In order to be compatible with the default EVP code, this requires changing
374        the EVP code around a little; and because any small change immediately
375        breaks the lab_sea.hb87 verification experiment, the reference output is
376        updated two times (each time the remaining aggrement was only 2 digits):
377        - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt
378        - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt
379        The adjoint test lab_sea.evp also needed to be updated.
380      - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting
381        SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be
382        a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps
383        explicitly with SEAICEnEVPstarSteps (thereby overriding the default of
384        INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately
385        kept obscure, because I need to test it a little more.
386    o pkg/cheapaml:
387      - fix few incorrect type (_RL/_RS) in subroutine calls.
388    o pkg/seaice:
389      - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays
390        to _RL vector; this fixes JFNK code when compiling with "-use_r4" option.
391    o model/src:
392      - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4;
393        change (in input_ad*/data) select_rStar from 2 to 1 for AD verification
394        experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output)
395    o pkg/cheapaml:
396      - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and
397        update output of experiment cheapAML_box.
398      - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity,
399        and set them only in one place (cheapaml_readparms.F).
400      - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI"
401      - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms)
402        and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia).
403    o model/src/the_main_loop.F:
404      - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION.
405    o pkg/seaice:
406      - remove legacy branch code.
407      - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly.
408    o verification/*/code*/SEAICE_OPTIONS.h:
409      - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY,
410        SEAICE_CAP_HEFF).
411    o pkg/cheapaml:
412      - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time
413        to load new forcing fields.
414      - add missing "_d 0" where it's needed; + some editing (improve indentation).
415      - remove switch to "-r8" compiler option (no longer needed) in verification
416        cheapAML_box, keep same output (small trucation error differences).
417    o verification/offline_exf_seaice:
418      - add thermodynamics only test.
419    o verification/cheapAML_box:
420      - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test;
421        keep same output (same 14 digits for cg2d).
422      - switch on "-r8" compiler option (some numerical values are missing
423        the "_d 0") and update output (only 6 digits for cg2d were preserved).
424    
425    checkpoint64b (2012/12/24)
426    o pkg/cheapaml:
427      - remove un-used variables (Qnet,EmPmR) from pickup files.
428      - store tendency of advected variables into cheapaml pickup file
429        and fix the AB-2 restart.
430    o verification/offline_exf_seaice and lab_sea adjoint:
431      - switch to new code (#undef SEAICE_GROWTH_LEGACY).
432      - switch to 4 time steps in offline, consistent with lab_sea.
433      - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice.
434      - update results after change of experiment seaice.
435    o pkg/seaice:
436      - remove option SEAICE_MULTICATEGORY; has been replaced with run-time
437        parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is
438        still defined since SEAICE_multDim needs to be set to MULTDIM value (from
439        SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default.
440    o model/src:
441      - add run-time parameter to select CG2D solver minimum-residual solution
442        (in case of a poor convergence).
443    o pkg/seaice/seaice_lsr.F
444      - move calculation of matrix coefficients into new
445        S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same
446        file; the main purpose of this change is to be able to reuse the code
447        in S/R SEAICE_PRECONDITIONER
448      - modify the computation of the residual so that the mass of sea-ice
449        is not used twice; this simplifies the calculations, but since
450        the residual is never used except when LSR_mixIniGuess.ge.4---and this is
451        not tested in testreport---this does not affect the testreport results.
452    o verification/seaice_obcs:
453      - disable SEAICE_GROWTH_LEGACY; reset input files to match those of
454        verification/lab_sea/input.salt_plume; changes results/output.txt*
455    o model/src:
456      - adapt quasi-hydrostatic formulation to work with p or p* coordinate.
457    o pkg/seaice:
458      - improve description of parameters in seaice_fgmres.F and start
459        cleaning up the code
460      - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of
461        second argument
462      - add a metric based on grid cell area to SEAICE_SCALPROD; update
463        results of offline_exf_seaice.dyn_jfnk
464      - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD
465    o pkg/aim_v23:
466      - fix an other bug in dissipation heating (grid-cell area was missing).
467    o model/src + pkg/seaice:
468      - add global (multi-tile) linear solver for pair of tri-diagonal system
469        along X and Y lines, respectively for U and V component.
470        Note: 1) MPI and cube-exchange not yet coded.
471            2) probably not accurate for poorly conditioned / large size problem.
472      - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver;
473        default: not compiled and not used.
474    o pkg/seaice:
475      - first attempt at a multi-threaded fgmres solver for the JFNK solver:
476        introduce bi/bj loops and use global_sum_tile_rl instead of
477        mpi_allreduce in seaice_fgmres.F
478      - improve diagnostics output for fgmres solver (seaice_fgmres.F)
479      - replace a few unnecessary goto statements by if-blocks  (seaice_fgmres.F)
480      - add a verification experiment for JFNK in offline_exf_seaice
481    o verification:
482      - change (for now, only fwd test) offline_exf_seaice experiment:
483        use a re-entrant channel with idealized coastline (trapezoidal shape)
484        at southern boundary to explore seaice dynamics and thermodynamics
485        with simple forcing. Main set-up has dynamics+thermo and SST relaxation;
486        secondary test (input.thsice) use thermodynamics only with SST relaxation.
487      - add seaice-dynamics only secondary test using LSR and pkg/thsice advection.
488    o pkg/exf:
489      - disable "sstExtrapol" when Nr=1
490    o verification:
491      - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble)
492        to test pkg/cheapaml.
493    o pkg/aim_v23 & pkg/shap_filt:
494      - fix dissipation heating (erroneous gravity multiplication factor).
495    o pkg/seaice:
496      - remove unused field pressPre from jfnk solver
497      - rename two subroutines in seaice_preconditioner.F
498    o eesupp/src:
499       - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...)
500    o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again
501       - remove wrong parts of the rhs and the lhs (were in there
502         because I did not understand the concept of this preconditioner)
503       - add an exchange between u- and v-sweep. This increases communication
504         by a factor of two but improves the convergence of jfnk. Ideally,
505         one would like the u- and v-sweep to be independent. So far within
506         undocumented ifdefs
507       - reorganize the extra computations for printing the residuals
508    o tools/genmake2:
509      - comment out the "mpif.h" include in NetCDF test programm (for MPI built)
510        since it's not necessary (and was preventing to use MNC in some cases).
511    
512    checkpoint64a (2012/11/16)
513    o pkg/autodiff:
514      - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that
515        autodiff_readparms.F no longer depends on calling order (within
516        packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h):
517        rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd
518        and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd.
519    o pkg/obcs:
520      - adding tidal velocity forcing capability to obcs
521        for usage example, see verification/seaice_obcs/input.tides
522    o pkg/seaice:
523      - turn the LSR-relaxation parameters WFAU/V into runtime parameters
524        SEAICE_LSRrelaxU/V
525      - introduce runtime parameter SEAICEetaZmethod (=0 by default)
526    o pkg/aim_v23:
527      - implement heating from friction (bottom friction and stratospheric drag).
528    o pkg/shap_filt:
529      - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from
530        dissipation but only for Shap_funct=2, active when addFrictionHeating=T.
531    o model/src:
532      - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in
533        time-constant addMass field from file (addMassFile);
534      - support for heating due to friction (and Kinetic Energy dissipation):
535        add option, run-time switch and 3-D field array + support code ; each pkg
536        or S/R can add heating contribution (if there is a sink of KE); the sum is
537        accounted for as a Temperature tendency term (EXTERNAL_FORCING_T).
538    o pkg/seaice:
539      - complete merge of ITD code into seaice_growth.F
540        from MITgcm_contrib/torge/itd/code/
541        no verification so far, but Torge Martin tested
542        "1-D test case and Beaufort set up;
543        deliver okay results after 1 model year."
544      - complete merge of SEAICE_SIZE.h into all relevant routines
545      - move computation of eta at Z-points into calc_viscosities
546        + introduce global field etaZ
547        + add different methods for computing etaZ, for now the old
548          method (simple averages of eta to Z-points) is hardwired
549        + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual,
550          seaice_preconditioner
551      - simplify computations for SEAICE_ZETA_SMOOTHREG
552      - seaice_preconditioner:
553        + replace one remaining press by pressLoc (mistake)
554        + adjust printing of residuals
555      - improve I/O of diagnostics of JFNK in seaice_jfnk.F:
556        + add (SEAICE.h) and rename some counters (initiliased in
557          seaice_init_fixed.F)
558        + add _BEGIN/END_MASTER (myThid)  around print statements
559        + print total number of iterations and failures over SEAICE_monFreq
560          interval to STDOUT
561      - move control over output-messages by fgmres to seaice_jfnk to save
562        some operations
563      - move resetting initial guess for fgmres outside of seaice_fgmres_driver
564        in order to make restarts with sol .ne. zero (fgmres with restarts)
565        (seaice_jfnk.F, seaice_fgmres.F)
566      - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
567        a serious convergence problem when open boundaries are involved
568    o pkg/ggl90: fix computation of control volumes for the case of
569      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
570      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
571    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
572    o pkg/autodiff
573      - Add inAdMode switch for SEAICEuseDYNAMICS:
574        SEAICEuseDYNAMICSinAdMode
575        (extend logic in ADAUTODIFF_INADMODE_SET)
576    o pkg/seaice
577      - Step 1 of merging ice-thickness distribution (ITD) code from
578        MITgcm_contrib/torge/itd/ (author: Torge Martin)
579        The code implements concept laid out in Thorndike et al. (1975);
580        code is enabled via CPP flag SEAICE_ITD
581        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
582        code is not complete yet!!
583      - SEAICE_SIZE.h now included in almost all seaice routines
584    o verification (using seaice):
585      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
586        global_ocean.cs32x15.seaice ; update results.
587      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
588      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
589        offline_exf_seaice (previously compiling B-grid).
590    o pkg/exf:
591      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
592        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
593        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
594    o pkg/layers (adjust changes from Sept 19):
595      - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)
596        this allows to remove "layers_maxNum" dimension from all layers arrays.
597    o pkg/layers (adjust changes from Sept 19):
598      - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ;
599      - snap-shot extended to all type of layers (not just the 1rst type);
600      - remove layers variables when corresponding CPP option is undef.
601    o pkg/layers:
602      - rename pkg/layers variable and add new output (layer exist & un-weighted
603        velocity in layer)
604    o pkg/seaice:
605      - simplify (?) ocean-drag coefficent computations by using
606        the same routine in all three solvers (saves some code lines)
607      - remove global fields DRAGA and DRAGS from C-grid code and
608        declare them locally in lsr.F (the only place where they are
609        still used)
610      - update AD output of lab_sea.evp (very sensitive anyway).
611    o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics
612      (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK
613      and SEAICEuseJFNK=.true. A few things to note:
614      - involves a FGMRES, that is parallel but very inefficient,
615        because of many scalar products (global sums) in the Gram-Schmidt
616        orthogonalization method. Needs to be replaced. Original code
617        from J.-F. Lemieux
618      - preconditioner for FGMRES is a stripped down version of LSOR
619      - SOLV_MAX_ITERS is now used for LSOR as a solver and as a
620        preconditioner. For the preconditioner, the default is set to 10.
621      - Jacobian times vector is computed with finite differences
622      - marginally related to JFNK-solver: add a smooth regularization for
623        zeta with tanh that will improve convergence (Lemieux and Tremblay,
624        2009) for any implicit solver (not implemented for EVP because EVP
625        does not need this regularization in the first place). Define
626        SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use.
627    o eesupp/src:
628      - check in genmake2 that intrinsic S/R flush is available.
629      - add S/R to flush IO unit (if intrinsic S/R flush is available)
630      - flush standard & error msg unit before MPI termination
631      - if debugMode, flush IO unit after printing msg
632    o pkg/ctrl:
633      - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call
634        to ctrl_set_unpack_xyz.
635    
636    checkpoint64 (2012/10/09)
637    o pkg/shelfice
638      - in mom_fluxform.F, mom_vecinv.F:
639        CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid)
640        Bug fix KappaRU -> KappaRV
641        does not change verification/isomip but may change other setups
642        (presumably constant KappaRU=KappaRV)
643      - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate)
644    o pkg/obcs:
645      - fixed some indexing bugs in obcs_seaice_sponge.F
646      - added obcs relaxation subroutines for HSALT and HSNOW
647      - changes verification/seaice_obcs/results/obcs_seaice_sponge.F
648    o pkg/seaice:
649      - add "multicategory" parameterization for snow in analogy to ice,
650        default is off for now.
651    o pkg/obcs:
652      - added obcs_seaice_sponge.F for obcs relaxation of seaice variables;
653        see verification/seaice_obcs/input.seaiceSponge for example application.
654      - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB
655        index setting by master-thread. This fix multi-threads Pb in previous modifs.
656    o pkg/layers :
657      - add diagnostics to pkg/layers
658      - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F
659        (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly.
660    o pkg/generic_advdiff/gad_implicit_r.F :
661      - fix ADVr diagnostics in case of both implicit vertical advection and diffusion.
662    o pkg/seaice/seaice_growth.F:
663      - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case.
664    o pkg/obcs:
665      - change default setting of OBCS_UVICE_OLD from defined to undef;
666      - use new parameter OB_indexNone for null index value (instead of hard-coded 0)
667        in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F;
668      - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z;
669      - change OB null index value (OB_indexNone) to -99 ; this fix the problem
670        with Southern & Western OB at a tile edge (at least in a simple set-up).
671    o pkg/obcs:
672      - change settings of OB index in case OB coincides with tile edge (shared by
673        2 tiles), so that common OB location is registered by both tiles (instead of
674        only 1). However, for Southern and Western OB, index value = 0 is not
675        recognized as valid OB index (=default null value) and needs to be fixed.
676      - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting)
677      - new parameter "OB_indexNone" for null index value (for now, still zero)
678        to replace hard-coded null index value of zero.
679    o pkg/exch2:
680      - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON:
681        always check buffer-size (but outside the loop); move checking for valid
682        index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON,
683        print each tile and point connection only if |W2_printMsg|>= 2 and 3.
684    o pkg/ctrl (pack & unpack):
685      - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable
686        (locally defined) for different variables (+ remove the variable-specific
687        file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL
688        (to be extended to other local file names in ctrl.h).
689    o pkg/flt:
690      - add a FLT_Iter0 option (similar to PTRACERS_Iter0).
691    o pkg/mdsio:
692      - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing
693    o tools/genmake2:
694      - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE
695        (added by Alistair in version 1.51 for building without make depend);
696      - remove Header files list (H_SRC_FILES) from the dependence of targets
697         ad_input_code.f & ftl_input_code.f (not clear why it was added in the first
698        place in version 1.23): this save going through staf when unrelated header
699        file has been modified.
700       Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without
701        "make depend" step, still need to do "make links" before "make adtaf".
702    o eesupp/src (+ few pkg src files) & genmake2:
703      - finish to remove ALWAYS_USE_MPI in source code that TAF does not see;
704      - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2).
705      - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish
706         upper/lower case ; account for space between "#" and undef/define)
707    o pkg/flt (with exch2):
708      - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F;
709      - simplify threads synchronisation; fix (many issues) multi-threaded with MPI.
710    
711    checkpoint63s (2012/09/05)
712    o pkg/ecco:
713      - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets.
714      - add more relevant #ifdef ALLOW_SMOOTH ones.
715      - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D.
716    o pkg/ctrl:
717      - CTRL_OPTIONS.h : document CPPs related to smoothing; ALLOW_SMOOTH_CORREL2D/3D,
718        ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D.
719      - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag,
720        doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and
721        ctrlSmoothCorrel3D (new).
722        The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP.
723      - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist.
724      - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress
725        controls when useAtmWind, and vice versa.
726      - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers.
727      - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with
728          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH.
729      - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with
730          #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH.
731      - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F:
732        replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D.
733    o pkg/smooth:
734      - remove un-necessary includes.
735      - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets.
736        Those CPP options were never defined, and not necessary.
737    o model/src:
738      - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi).
739      - standard treatment of useSMOOTH.
740    o pkg/autodiff:
741      - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode,
742        useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint.
743    o pkg/exch2:
744      - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template)
745        + start to remove ALWAYS_USE_MPI in source code that TAF does not see.
746      - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag
747        and tiles to process mapping.
748      - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h)
749        moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h;
750        rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX
751        from w2_eeboot.F to w2_readparms.F.
752    o eesupp/src:
753      - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of
754        ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F;
755        also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F
756      - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI
757        is defined (remove condition on usingMPI) to match cases where MPI_INIT
758        has been called.
759      - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used);
760      - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings
761        (so that on 1 proc, get same myPid independently of usingMPI)
762      - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and
763        useCubedSphereExchange with EXCH-1 (safer).
764      - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI).
765    o pkg/ggl90:
766      - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call)
767        used in ALLOW_GGL90_SMOOTH code.
768    o pkg/flt:
769      - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping
770        floats at the Southern end of the domain).
771    o eesupp/inc:
772      - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h);
773        but not used (and not to be used) anywhere, just for documentation.
774    o pkg/autodiff, exf, ptracers & seaice (AD & TL output):
775      - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since:
776        a) can damage previously written records in any other multi-record files.
777        b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S.
778    o tools/genmake2:
779      - define variable MAKE within Makefile and use it in place of 'make';
780      - update AD_CONFIG.h (if needed) before building any of the executable
781        (forward, adjoint or tangent-lin); this involves a 2nd invocation of make;
782        and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h;
783      - always print usual warning comment 'this file is automatically generated'
784        from script convert_cpp_cmd2defines (+ remove this warning from genmake2).
785    o pkg/cheapaml:
786      - updated to correspond to the code used in accepted paper (Nico Wienders).
787    o pkg/exf:
788        added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch.
789        ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F)
790        and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h).
791    o pkg/exf, autodiff, ctrl, ecco and seaice:
792        remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones.
793    o pkg/ctrl, ecco:
794        allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL.
795        Depending on useAtmWind, one is inactive, and the other is active (see
796        exf_getffields.F/exf_getsurfacefluxes.F).
797    o tools/genmake2:
798      - improve error msg when failing in 2nd test of check_for_broken_Ff
799      - fix option '-makefile' short-name (-mf according to genmake2 -help)
800      - source local config file "genmake_local" just after processing the genmake2
801        command arguments (previously done before processing arg).
802    o pkg/grdchk:
803      - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call
804        to this routine from cost_final has been dropped in g_cost_final)
805      - improve printed information (more explicit msg, no longer using "print *,"
806         fix fcpertminus printed value).
807    o model/src:
808      - move call to COST_INIT_VARIA out of packages_init_variables.F directly
809        into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES):
810        this prevents getting cost-funct reset in adinitialise_varia recomputations.
811    o pkg/dic:
812      - move initialisation of "freefe" array from from dic_biotic_forcing.F to
813        fe_chem.F: this prevents TAF from dropping this initialisation in TLM code.
814    o pkg/grdchk:
815      - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid )
816      - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0
817    o pkg/autodiff/ctrl/grdchk :
818      - attempt to sort out what works and what does not,
819        with regard to I/O, and to warn/stop accordingly.
820    o pkg/grdchk:
821      - attempt to fix grdchk in the case of useSingleCpuIO.
822      - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )"
823       statements were moved from grdchk_main.F and into
824       grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F.
825      - a global sum is applied to record numbers icvrec/layer
826       out of grdchk_loc so that they be passed to I/O routines.
827    o pkg/smooth:
828      - fix recomputation that appeared with nlfs : use smooth_recip_hFacC,
829        smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case.
830    o verification/testreport:
831      - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive);
832      - can also use compressed (gzip) reference output file;
833      - change format (in pkg/grdchk) of TLM output (+ add forward gradient)
834        to be easier to collect by testreport.
835      - update existing TLM output (half out-of-date by more than 3 yrs).
836      - report NETCDF & LAPACK settings (from genmake2) in output dir.
837      - report run-time in each individual summary (previously only for AD test);
838        for TLM test, add also TAF version.
839      - add daily TLM test on (old) aces cluster + weekly test on baudelaire.
840    
841    checkpoint63r (2012/08/15)
842    o tools/genmake2:
843      - fix Makefile for target ftlall (+ update files to clean after make ftlall)
844    o pkg/ecco/ecco_cost_final.F :
845      - fix fc print statements (to stdout and costfunction0000) so
846        that the printed value is always after the global sum.
847    o pkg/seaice/seaice_dynsolver.F :
848      - fix ice strength assymptote at SEAICE_area_max<1
849        (no change for the standard case of SEAICE_area_max=1)
850    o some cleaning:
851      - pkg source files: ensure that all *.F files from each pkg included the
852        corresponding ${PKG}_OPTIONS.h file (except stand-alone src file which
853        only includes CPP_EEOPTIONS.h); fix S/R CTRL_SMOOTH ; update AD experiment
854        code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding
855        includes;
856      - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used.
857      - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR
858        is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when
859        ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop.
860      - update option-file CPP_OPTIONS.h of all AD experiments:
861        * no longer include PACKAGES_CONFIG.h ;
862        * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ;
863        * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before
864          including ECCO_CPPOPTIONS.h).
865    o pkg/cost, pkg/ctrl, pkg/ecco option-file:
866      - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into
867        separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h,
868        not necessary accurate).
869      - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in
870        pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to
871        deliberately break compilation (a remainder that it needs to be customized)
872      - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h
873      - rename COST_CPPOPTIONS.h to COST_OPTIONS.h
874      - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h
875    o tools/genamke2:
876      - check for lapack.
877    o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies.
878      - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions
879        jointly. The exclusive ifdefs were removed, to add costs terms (when defined)
880        from both packages.
881      - the fc global sum in pkg/ecco/ecco_cost_final.F was removed accordingly.
882      - for objf_atl we use either the pkg/ecco or the pkg/cost term depending on CPPs.
883      - pkg/ecco and model/src : add CPP brackets around pkg/cost and pkg/ctrl includes
884        of "CTRL_SIZE.h" "ctrl.h" "ctrl_dummy.h" "optim.h" / "cost.h" accordingly.
885    o pkg/cost : add comments to explain special and/or untested setups.
886    o pkg/exf:
887      - use EXF_OPTIONS.h to set pkg/exf options except if done in ECCO_CPPOPTIONS.h
888        (previously, ALLOW_AUTODIFF_TAMC was controling this switch).
889    o verification/*/code_ad:
890      mimimal cleaning of AD experiments ECCO_CPPOPTIONS.h option-file:
891      - reccord when this file is included (define ECCO_CPPOPTIONS_H)
892      - remove the most obvious obsolete features (e.g., #define ALLOW_COST not
893        allowed since Oct 2003 in any option-file except in PACKAGES_CONFIG.h)
894    o pkg/seaice :
895      - added possibility to change ice strength/PRESS0 relationship to
896        HEFF, according to the following run time parameters
897        SEAICEpresPow0 :: HEFF exponent for ice strength below SEAICEpresH0 (integer, >0)
898        SEAICEpresPow1 :: HEFF exponent for ice strength above SEAICEpresH0 (integer, >0)
899        SEAICEpresH0   :: HEFF threshold for ice strength            (m)
900    o pkg/ggl90 :
901      - added run time flag mxlSurfFlag to include the code that ensure
902        mixing between first and second level (previously included as a comment)
903    o verification/1D_ocean_ice_column/input_ad/data.autodiff :
904      - add test of newly added dumpAdByRec=T option where
905        we write all records to one file per variable.
906    o verification/global_ocean.cs32x15/code_ad/CPP_OPTIONS.h :
907      - switch to #define ALLOW_BALANCE_RELAX and ALLOW_BALANCE_FLUXES
908        to check that this code is ok with taf and compiles in adjoint.
909    o pkg/autodiff :
910      - added run time param dumpAdByRec : ad dump format switch.
911        If true then write all records to one file per variable.
912        Else write one file per record (remains the default).
913      - revise seaice_ad_dump.F and exf_adjoint_snapshots_ad.F accordingly.
914    o pkg/seaice:
915     - Added SEAICEuseTILT run time switch : if set to
916       false then omit the tilt term in seaice dynamics.
917     - Fix free drift calculation.
918    o pkg/shelfice:
919      When initializing SHELFICEDragQuadratic, set default to be
920      consistent with shiCdrag in case SHELFICEuseGammaFrict is used,
921      but retain option to set it independently
922      (inconsistenty spotted by Veronique Dansereau)
923    o eesupp/inc:
924      - in EEPARAMS.h, add real-type constant for some frequently used simple number
925         (0,1,2,1/2), with name explicitly referring to RS/RL type.
926    o model/src:
927      - move balancing of relaxation terms to new S/R balance_relax.F.
928    o pkg/autodiff:
929      re-write active I/O high-level (control) S/R:
930      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
931      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
932      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
933        MDS_READ/WRITE_FIELD); change loops to multi-threads.
934      - update and merge active_file_control_slice.flow into active_file_control.flow
935      - update the calls in lower level S/R (active_file.F, active_file_g.F and
936        active_file_ad.F) keeping the argument list and function unchanged.
937      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
938        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
939      - new low-level active I/O routines, one for each type (RL/RS), for active var
940        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
941        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
942        right type.
943    o autodiff and RS=real*4:
944      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
945        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
946      - change argument type of 3-D mask argument to _RS to match type in the call
947        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
948    o pkg/thsice:
949      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
950      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
951        fresh-water flux: uniform correction or proportional to local precip.
952    o pkg/ctrl:
953      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
954      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
955                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
956      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
957    
958    checkpoint63q (2012/07/30)
959    o pkg/autodiff:
960      note about monitor and snap-shot of ad-variables:
961      a) need to apply ADEXCH before monitor or output of ad-vars to include
962       overlap contributions (was done for adjDump but missing for monitor).
963      b) since ADEXCH implies adding overlap values to interior array, machine
964       truncation error is expected when adding an ADEXCH call in the middle of
965       the time-stepping (although mathematically identical).
966      modifs:
967      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
968        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
969      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
970        apply ADEXCH before monitor or snap-shot of ad-variables:
971           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
972      - implement new method (copy+adexch) for snap-shot and monitor of main model
973        ad-vars (initially not used by default -> output unchanged).
974      - change default (set to 2) to use new method and update few output_adm.txt
975        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
976        and both tutorial_tracer_adjsens tests).
977      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
978        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
979    o pkg/ctrl:
980      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
981      generic control variables via
982      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
983      Only required customization should be S/R ctrl_map_ini_genarr.F
984      (routine in repository contains example)
985    o pkg/exf:
986      - fix and refine checking of surface-relaxation setting when using EXF
987    o verification (adjoint exp):
988      - reduce length of simulation by half for experiment global_ocean.cs32x15
989        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
990    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
991      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
992        of KE that can occur with aggressive optimization
993      + put quadratic bottom drag calculation in separated loops (only done if
994        using bottomDragQuadratic)
995    o model/src: CG2D_NSA
996      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
997         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
998      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
999         change cg2d residual target to be expressed in Wunits (=> do not normalise
1000         RHS ; this fix global_max Pb with TAF); update output.
1001    o verification/tutorial_tracer_adjsens:
1002       improve parameter consistency (and get rid of warnings):
1003       - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
1004       - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
1005       - use staggerTimeStep (for stability) in som81; use default rotation period.
1006    o pkg/exch2:
1007      - with empty facet: fix compact-format (W2_mapIO=1) definition (was previously
1008        reset to 0 = 1 long line in X)
1009    o pkg/mdsio:
1010      - fix reading of dimensions from meta file for large-size domain
1011    o model/src:
1012      - fix saltIsActiveTr setting for IdealGas eosType (eosType is 6 character long);
1013      - to refine CS-grid check, add logical flag "hasWetCSCorners": true if using
1014        Cubed-Sphere Exch with CS-corners inside the domain;
1015        make new S/R INI_GLOBAL_DOMAIN from code in ini_linear_phisurf.F to calculate
1016        globalArea and to set hasWetCSCorners.
1017      - add warning if usingCurvilinearGrid and momAdvection in flux-form (missing
1018        metric terms); stop if hasWetCSCorners=T and momAdvection in flux-form.
1019      - re-activate the stop if useCDscheme and hasWetCSCorners=T (previously if
1020        useCDscheme and useCubedSphereExchange).
1021    o pkg/seaice/seaice_growth.F :
1022      - compute the SEAICE_DISABLE_HEATCONSFIX term accordingly
1023        for the (.NOT.useRealFreshWaterFlux).OR.(nonlinFreeSurf.EQ.0)
1024        when the previous code was not correct.
1025      - in all cases diagnoze the boundary condition mismatch to SIaaflux
1026      - in the case of useRealFreshWaterFlux.AND.(nonlinFreeSurf.GT.0) add
1027        that term to QNET (essentially to set the melt/freeze water to 0degC).
1028        when SEAICEheatConsFix is true, so that the ocean+ice budget heat is closed.
1029    o verification/global_ocean.cs32x15/input.seaice :
1030      - add SEAICEheatConsFix in data.seaice, ensuring closed ocean+ice heat budget.
1031      - add diagnostics (commented out) for budget test using my matlab codes (gcmfaces).
1032      - update results (output.seaice.txt) accordingly.
1033    o verification/lab_sea/input/data.seaice :
1034      - remove SEAICEheatConsFix, which is now be tested
1035        in global_ocean.cs32x15. The presently coded fix
1036        is only consistent with real fresh water + nlfs.
1037      - update results (output.txt) accordingly.
1038    o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
1039    o AD_CONFIG.h file:
1040      - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
1041      - remove #include "AD_CONFIG.h" from all included OPTIONS files and
1042        add it explicitly in each fortran src file where it is needed.
1043        motivation: header file AD_CONFIG.h is generated/modified after "make depend"
1044        thus introducing potentially wrong dependency; therefore, better to include
1045        it only where it's really needed, and after any other included OPTIONS file
1046        (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
1047        or ALLOW_TANGENTLINEAR_RUN).
1048    
1049    checkpoint63p (2012/07/06)
1050    o pkg/autodiff:
1051      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
1052      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
1053        which are now read from new parameter file "data.autodiff" (inAdExact
1054        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
1055      - add file "data.autodiff" in all verification/*/input_ad/ directories.
1056      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
1057        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
1058    o verification/tutorial_tracer_adjsens/
1059      - add extra sub-verification which uses "SOM" advection scheme
1060        (2nd Order-Moment Advection Scheme, Prather Limiter) with
1061          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
1062        and in data:
1063          multiDimAdvection=.TRUE.,
1064          tempAdvScheme=81,
1065          saltAdvScheme=81,
1066    o model/src:
1067      - introduce ALLOW_BALANCE_RELAX which allow the removal
1068       of the global mean of relaxation terms by setting
1069       balanceThetaClimRelax and balanceSaltClimRelax
1070      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
1071       This case is now treated appropriately in seaice_growth.F
1072    o pkg/seaice:
1073      - do balanceEmPmR and balanceQnet based on the net fluxes
1074        (SItflux) that enter the ocean+ice system rather than QNET
1075        and EMPMR. Works best in real fresh water.
1076      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
1077        out of the diagnotics bloc, and stored in global arrays.
1078    
1079    checkpoint63o (2012/06/29)
1080    o vertical mixing schemes:
1081      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
1082      - replace computation of density (in Function STATE1, opps_calc.F) by a call
1083        to S/R FIND_RHO_SCALAR
1084      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
1085        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
1086        affects output (vermix.ggl90) at truncation level.
1087    o testreport:
1088      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
1089        (nSx,nSy) for the number of threads (from eedata.mth)
1090    o model/src:
1091      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
1092        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
1093    o verification/tutorial_tracer_adjsens/
1094      - compile with ALLOW_CG2D_NSA
1095      - run with nonlinFreeSurf=3
1096      - update reference output_adm.txt
1097    o tools/genmake2:
1098      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
1099        refine usePROFILES switching off (only when NetCDF is not available).
1100    o verification (atmospheric set-up):
1101      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
1102    o pkg/profiles : refine profiles and files handling.
1103    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
1104    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
1105      - changes to use model/src/the_main_loop.F rather than the ecco version
1106        in ecco type adjoint runs.
1107    o model/src:
1108      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
1109      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
1110      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
1111    o model/src:
1112      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
1113        update output of test experiment bottom_ctrl_5x5.
1114    o pkg/generic_advdiff:
1115      - implement vertical bi-harmonic diffusion (for now, only for T & S and
1116        only explicitly).
1117    o verification/bottom_ctrl_5x5/
1118      update reference output (results changed quite some time ago,
1119      not sure when; but new reference results look ok in terms of grdchk)
1120    o verification/1D_ocean_ice_column/
1121      For verification purposes, the exact adjoint rather than an approx.
1122      should be used (e.g., to comare against F.D. or TLM).
1123      removed autodiff_inadmode*_ad.F routines in code_ad/
1124      Update results/ accordingly.
1125    o pkg/cal:
1126      - change cal_getdate.F so that output date is function of input time only
1127        (less ambiguous, not mixed up with input iteration number).
1128      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
1129    o pkg/diagnostics:
1130      - implement calendarDumps also for stats-diags
1131      - implement calendarDumps also for snap-shot output (negative freq)
1132      - for now, ignores calendarDumps if non-zero phase-lag.
1133    
1134    checkpoint63n (2012/06/04)
1135    o model/src:
1136      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
1137        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
1138      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
1139        similar to calc_r_star.F); update results of experiment internal_wave and
1140        tutorial_global_oce_in_p (affected @ truncation level).
1141    o pkg/shelfice:
1142      - add parameterisation of advective-diffusive flux into the ice shelf
1143        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
1144      - simply eps3/3a computation
1145    o eesupp:
1146     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
1147       between tiles, just fill-in edges assuming locally periodic subdomain) and
1148       add corresponding exchange subroutines (EXCH0);
1149     - new CG-solver version (_EX0) for disconnected-tiles special case.
1150    o model/src (CG-solvers):
1151     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
1152       (similar final residual output and max-Iter number as with standard version);
1153     - allows to store and use lowest-residual solution (standard & _SR versions);
1154     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
1155     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
1156    o eesup/src:
1157     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
1158       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
1159    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
1160    
1161    checkpoint63m (2012/04/27)
1162    o pkg/shelfice:
1163     - account for partical cells in surface level below ice-shelf for hydrostatic
1164       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
1165    o ad test experiments:
1166     - update and rename to "ad_optfile.local" local AD-optfile specific to a
1167       particular adjoint verification experiment (in verification/*/code_ad/)
1168    o pkg/seaice & pkg/exf:
1169     - Part two of ECCO-CLIVAR code merges.
1170       Completes merge of seaice area relax. code.
1171       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
1172       to be set in EXF_OPTIONS.h since this pkg controls its I/O
1173       (and avoids second CPP option in SEAICE_OPTIONS.h)
1174     - change default value of costIceStart & costIceEnd to a valid date.
1175     - add snowPrecip to HSNOW in seaice_growth
1176    o pkg/ptracers:
1177     - move ptracers summary and setup check into separated S/R ; add a check for
1178       valid PTRACERS_Iter0 value (error+stop or just warning).
1179    o pkg/cal (+ pkg/ecco):
1180     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
1181       as input; and for AD, unless both are not differentiable (e.g., k index)).
1182    o model/src:
1183     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
1184       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
1185       temporary set to usingZCoords value (to be changed to F when using shelfice).
1186     - hydrostatic pressure: implement partial cell near the surface also for
1187       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
1188       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
1189    o pkg/ctrl/ctrl_init.F:
1190     - add a formal parameter to s/r ctrl_init_rec to print
1191       xx_$(ctrl_valiable)_file for easier debugging
1192     - move call of cal_* routines into the if-block where they are really
1193       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
1194       to specify a startdate
1195    o pkg/seaice:
1196     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
1197       global_ocean.cs32x15/code versions).
1198     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
1199       verification experiment global_ocean.cs32x15.seaice and update results.
1200    o pkg/exf:
1201     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
1202       (according to useExfYearlyFields).
1203    o pkg/cal:
1204     - move calendar setting & summary (previously in cal_readparams.F) into new
1205       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
1206       length of the simulation is set (after SET_PARMS call); This is an attempt
1207       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
1208     - For safety: keep a record of pkg/cal parameter settings status
1209               to allow to STOP if one pkg/cal S/R is called too early.
1210     - add a stop in all basic pkg/cal subroutines if called before setting is done.
1211     - modify cal_getdate.F: stop when nothing was returned;
1212       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
1213       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
1214    
1215    checkpoint63l (2012/04/04)
1216    o pkg/bbl:
1217      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
1218        update global_with_exf output.yearly.txt file.
1219    o pkg/cal:
1220      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
1221      - remove 2 unsused and very short (1 line only) functions ;
1222      - remove unsused subroutines from AD-Diff list.
1223    o model/src:
1224      - start to implement clean wait to stop in initialization S/R (config_check.F,
1225         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
1226    o folowing PRINT_MESSAGE changes:
1227      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
1228    o pkg/bbl:
1229      - modification so it can work with z*
1230      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
1231      - global_with_exf/input.yearly verification; changes output.yearly.txt
1232    o eesupp/src:
1233      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
1234        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
1235      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
1236        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
1237      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
1238      - when using MPI, always set usingMPI=T ; set default accordingly and stop
1239        if not consistent.
1240      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
1241        argument is zero (in case called within single-thread section).
1242    o pkg/fizhi:
1243        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
1244        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
1245    o pkg/exch2:
1246      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
1247        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
1248      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
1249        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
1250        with bad ones coming from a not-yet-updated halo.
1251        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
1252    o pkg/frazil:
1253        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
1254        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
1255    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
1256    o verification/lab_sea
1257      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
1258      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
1259      * nTimeSteps 3 -> 4
1260      * changed reference output accordingly
1261    o pkg/ctrl:
1262      * fix ctrl_get_gen for xx_sst, xx_sss
1263    o pkg/fizhi:
1264      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
1265        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
1266      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
1267        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
1268        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
1269    o pkg/gmredi:
1270      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
1271    o pkg/fizhi:
1272      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
1273        (old)aces open64 tuv test.
1274    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
1275    o pkg/mom_vecinv:
1276      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
1277        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
1278        with non-lin free-surf).
1279    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
1280      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
1281      some compilers (gfortran 4.6.0 on MacOS)
1282    o momentum:
1283      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
1284        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
1285        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
1286    
1287    checkpoint63k (2012/03/17)
1288    o model/src:
1289       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
1290         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
1291       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
1292         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
1293    o model/src: solve_*diagonal.F
1294       - replace division with multiplication by inverse (similar to original version)
1295         update output of AD exp. global_ocean.90x40x15.
1296       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
1297         to enable the use of the vectorized & differentiable solve_tridiagonal.F
1298       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
1299         vertical advection (to get solve_tridiagonal tested in AD mode).
1300    o pkg/seaice: ECCO-CLIVAR merge:
1301      1. seaice AREA relaxation
1302         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
1303         * runtime flag: SEAICE_tauAreaObsRelax
1304      2. modified global mean cost imbalance code: CPP option
1305          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
1306    o another iteration on solve_*diagonal.F
1307       Make choices independent of AUTODIFF
1308       Default will be the adjoinable vectorized version.
1309       Alternative choices are:
1310       * non-adjoinable original version with low memory footprint:
1311         #define SOLVE_DIAGONAL_LOWMEMORY
1312       * still adjoinable but does not vectorize (k as inner-most loop):
1313         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
1314    o testreport
1315     - add option to use a home made wrapper around "make"
1316     - remove MITGCM_IEEE env. variable (no longer active)
1317    o pkg/shelfice
1318     - improve computation of friction velocity for velocity dependent
1319       exchange coefficients: include velocities into SHELFICEBoundaryLayer
1320       block to average velocities vertically
1321     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
1322    o Modify diagonal solvers, now three versions (upon request):
1323      #ifndef SOLVE_DIAGONAL_AUTODIFF
1324        1. default version (dating back a while ago)
1325      #else /* def SOLVE_DIAGONAL_AUTODIFF */
1326      # ifdef SOLVE_DIAGONAL_KINNER
1327        2. adjoinable version with k-innermost loop (G. Forget)
1328      # else
1329        3. adjoinable vectorized version of 2.
1330      # endif
1331      #endif /* SOLVE_DIAGONAL_AUTODIFF */
1332      All flags are currently set within routines, but could/should be moved to CPP-options.
1333      Array bounds for 1. are as before, for 2.,3. cover the entire domain
1334      (could be changed for 1. too).
1335    o verification/lab_sea (fwd):
1336      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
1337        use 7 categories (except hb87), new solve4temp params (except salt_plume),
1338        constant salinity (=4) or variable salinity (salt_plume) done through
1339        SItracer.
1340    o pkg/seaice:
1341      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
1342      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
1343         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
1344        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
1345        SEAICE_freeze got retired) but already better than previously with
1346        SEAICE_freeze=123456.7 deg.C;
1347      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
1348        (safer multi-threaded setting); always set SEAICEuseEVP;
1349      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
1350        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
1351        stop if multiple specifications for the same coeff; make sure default
1352        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
1353    o pkg/obcs:
1354      - allow to switch to upwind 1rst order advection scheme for the advective
1355        flux computation at the open-boundary; disabled for adjoint built.
1356    o pkg/ptracers:
1357      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
1358      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
1359      - add parameter to decide when to start a tracer; use internal flag to
1360        know which tracer to step-forward; switch this internal flag at the top
1361        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
1362        for adjoint built.
1363    o pkg/seaice:
1364      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
1365      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
1366      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
1367    o pkg/ecco:
1368      - fix writing of output file DiagnosCost_ClimSalt/Theta
1369        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
1370    o pkg/seaice:
1371      - add missing initialisation of COR_ICE array in dynsolver.F
1372      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
1373        compiled either way, and is tested in all exps (multidim was only tested
1374        in lab_sea ad before).
1375      - cosmetic change to prepare for future addition of ITD. no change to results.
1376        no defaults change.
1377      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
1378      - by lack of adequate verification experiments, I further used custom versions
1379        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
1380        should be correct.
1381      - avoid recomputations in ad.
1382    o array initialisation in adjoint mode:
1383      1) pkg/mom_common/mom_calc_ke.F:
1384        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
1385        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
1386        part this initialisation is gone, resulting in Floating Point Exception
1387        (caught by open64 compiler with debug option).
1388      2) model/src/convective_weights.F
1389        set output convectCount over the full array range (instead of doing
1390        an update): this fix a similar issue when called within recomputation (adjoint)
1391        which could by-pass the initialisation (normally done in the caller S/R).
1392    o pkg/seaice:
1393      - final version of turbulent flux params, as agreed at MIT ice meet:
1394           SEAICE_mcPheePiston (default is ~ 0.000875)
1395           SEAICE_mcPheeTaper (default is 0.)
1396           SEAICE_frazilFrac (defualt is 1.)
1397           SEAICE_mcPheeStepFunc (default is false)
1398      - changes results at trunction error level
1399      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
1400    o added pkg/frazil:
1401      - see frazil_description.tex for details
1402      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
1403    o pkg/shelfice/shelfice_thermodynamics.F
1404      - fix exponents for velocity dependent exchange coefficients: change
1405        from 2/3(=0) to 0.66666666666666667
1406      - move computation of velocity dependent exchange coefficients into
1407        separate loop, so that it applies to both thermodynamics
1408      - move some divisions by constants out of loops
1409    
1410    checkpoint63j (2012/02/16)
1411    o pkg/seaice:
1412      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
1413      - SItracer:  added run time params, and allow coupling to ocn salinity.
1414    o pkg/seaice: remove (almost) all divisions by constants within loops
1415      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
1416      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
1417      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
1418      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
1419    o pkg/seaice :
1420      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
1421        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
1422      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
1423      - add permanent SItflux diag that corresponds to TFLUX but includes
1424        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
1425      - allow activation/testing of a fix for suspected missing term in
1426        ocn-ice heat budget (to be confirmed). To test this, you want to
1427        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
1428        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
1429      - no change in results, fwd or ad.
1430    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
1431      - switch to variable freezing point.
1432           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
1433      - bug fix : the sublimation term that was missing is now activated.
1434           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
1435      - bug fix : flooding sign term for SIsal0.NE.0.
1436           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
1437    o pkg/seaice:
1438      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
1439        is now the default, and the old default constant freezing point is recovered
1440        with SEAICE_tempFrz0    = -1.96,
1441             SEAICE_dTempFrz_dS = 0.,
1442      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
1443      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
1444      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
1445        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
1446      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
1447        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
1448      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
1449        seaice_growth r149 for legacy branch (no results change).
1450      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
1451        from I. Fenty).
1452      - results did not change except for global_ocean.cs32x15, mostly due to the
1453        switch to variable freezing point (see above item for detail).
1454    o pkg/thsice:
1455      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
1456        seawater freezing in thsice_calc_thickn (not used).
1457    o pkg/seaice: turbulent flux term specification via run time params.
1458      - replace CPP switches with run time switches to facilitate testing
1459      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
1460                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
1461      - added runtime parameter : SEAICEturbFluxFormula
1462      - move Mcphee constants to SEAICE_PARAMS.h
1463      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
1464                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
1465                 remove seaice_summary call (moved to seaice_init_fixed)
1466      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
1467        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
1468      - seaice_summary.F : add missing report of read turbulent flux term set up
1469                           and SITRACER.
1470      - seaice_check.F : check range; inform and stop if retired CPPs are used
1471                         (incl. SEAICE_AGE).
1472      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
1473             CPP switch, same computation as before for the different options.
1474      - change results at the truncation level.
1475    o pkg/seaice:
1476      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
1477        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
1478        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
1479      - update verification/*/input*/data.seaice:
1480        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
1481        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
1482        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
1483        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
1484    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
1485      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
1486        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
1487        difference in results only due to machine truncation.
1488      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
1489        MaykutPolySatVap; keep MIN_LWDOWN.
1490      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
1491      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
1492        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
1493    o pkg/salt_plume:
1494      - isolate saltPlumeFlux array exch into a specific S/R called from
1495        do_oceanic_phys.F
1496      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
1497    o verification:
1498      - move untested set-up to MITgcm_contrib/verification_other.
1499    o pkg/seaice:
1500      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
1501    o pkg/seaice:
1502      - seaice_solve4temp.F (keeping results unchanged):
1503        * add 2 future run-time params to select which saturation vapor pressure
1504          formula is used and how post-iteration fluxes are set.
1505          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
1506        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
1507          the linearized expression to stay consistent with tsurf finding.
1508      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
1509        can be < 0.
1510    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
1511      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
1512        conductive heat flux F_c , and add it explicitly when updating tsurf as
1513        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
1514        so that now F_ia has a consistent meaning through the entire routine.
1515        This causes differences at truncation level: update output of fwd exp.
1516        global_ocean.cs32x15.seaice.
1517    o pkg/seaice:
1518      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
1519        of arrays, sign/direction of fluxes; no effect on results.
1520      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
1521        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
1522        note: this should have been done before changing celsius2K default.
1523      - to keep results unchanged, add back old value of celsius2K in verification
1524        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
1525      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
1526        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
1527        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
1528        freezing temp is consistent with value in seaice_growth.F ; this causes
1529        differences at machine truncation level: update lab_sea AD output (3/4).
1530    o pkg/seaice:
1531      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
1532        and climsst/sss even when using seaice (to prevent calculation that might
1533        use SST on land); does not affect any verification exp.
1534      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
1535        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
1536    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
1537      over land (non-legacy code)
1538    o vectorize salt_plume package:
1539      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
1540      - this code computes plumebk everywhere (also over land), thus requires
1541        code to avoid divisions by zero and catch the case of kLev=Nr.
1542      - efficiency of salt_plume_frac is still sub-optimal
1543    o tools (genmake2):
1544      - fix makefile NAME specification (option: -makefile NAME) by adding
1545        "-f $MAKEFILE" in few places where it was missing including makedepend
1546        command (contribution from Paul).
