4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  untagged  o seaice pkg: add a cpp-flag to include a simple formula for a salinity
8      depend freezing point of sea water at the surface
9    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
10       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
11       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
12    o pkg/diagnostics: add options and parameters for regional-statistics
13       diagnostics ; define regions by reading a region-mask from a file
14       (might add other options later)
15    o pkg/bulk_force:
16     - add option and parameters to use AIM surface-flux formulae.
17     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
18       others forcing fields (defined in PARM05, parameter file "data") are loaded
19       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
20     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
21     - use the right EXCH call for uwind,vwind (to work on CS-grid).
22     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
23       and parameters (note: calcWindStress replaces .NOT.readwindstress).
24     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
25    
26    checkpoint58
27    o add "--embed-source" option to genmake2 which, when the supporting
28      tools can be compiled (as determined by genmake2) will turn on the
29      embed_files package which then embeds the entire MITgcm source code
30      (*.[fFhc] + Makefile) used for the build within the executable
31      - requested by CNH but off by default
32      - adds a paltry <9MB to the mitgcmuv executable in most cases
33      - only writes the output when useEMBEDSRC in eedata is true
34    o clean up 3-dim. relaxation codes:
35      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
36      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
37      * Thanks to Tom Haine for testing!
38    
39    checkpoint57z_post
40    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
41      affects output (@ truncation level) of exp. plume_on_slope ; updated.
42    o fix the pickup behavior for obcs in combination with ptracers
43    o fix a bug in ptracers_external_fields_load
44    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
45      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
46    o transfered surface NH pressure to eta field (if exactConserv).
47    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
48         and update lab_sea output.txt file.
49    o completing 3-dim. relaxation code: additional term
50         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
51      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
52      * At compile time, in "EXF_OPTIONS.h" set
53          #define  ALLOW_CLIMTEMP_RELAXATION
54          #define  ALLOW_CLIMSALT_RELAXATION
55      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
56          tauThetaClimRelax3Dim = 15552000.0,
57          tauSaltClimRelax3Dim  = 15552000.0,
58      * 3 cases:
59          1) Use a constant-in-time 3-dim. field
60          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
61          3) Real-time relax. to time-evolving prescribed field
62    o Adding Laplacian-type smoothness constraint on
63      initial and boundary (forcing) controls (ic, bc)
64      * enable at compile-time via
65        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
66      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
67      * Absolute scale somewhat unclear so far
68      * no area weighting was included since no other cost term does so far
69    
70    checkpoint57y_post
71    First step for a NLFS adjoint
72    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
73    o new init. routines for calc_r_star, calc_surf_dr
74    o still need to deal with ini_masks_etc
75    o testreport seemed happy
76    checkpoint57y_pre
77    
78    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
79    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
80    o add new offset feature to offline pkg (plus minor cleanup)
81    o cfc fixes for final year of integration
82    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
83      be in GCHEM_OPTIONS).
84    
85    checkpoint57x_post
86    o fix testreport Pb in multiple test experiment.
87    o cleanup our namelist syntax in verification:
88      - make it more F95 standards compliant (some work still needed)
89      - allows the vast majority of our tests to work with gfortran
90    o Non-Hydrostatic:
91     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
92     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
93    o Allow to apply AB on T,S rather than on AB(gT,gS):
94     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
95     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
96       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
97     - need a "clever" read_pickup to restart from the other AB formulation
98    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
99    o remove some unused variables (reduces number of compiler warnings)
100    o adjoint
101      * Disable useVariableViscosity for adjoint for time being
102        (there are a number of extensive recomputations)
103      * Initialize certain variables needed for adjoint
104    
105    checkpoint57w_post
106    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
107                 fix the singleCpuIO RS version of MDSWRITEFIELD
108       and add a WARNING if using globalFiles=T with multi-processors.
109    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
110      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
111    o tracer advection scheme:
112      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
113       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
114       was not very convenient).
115      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
116       (further tests needed for the implicit DST & Flux-Limiter schemes).
117    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
118      and sRef for convenience, handy, when you want to initialize
119      ptracers in a large domain with a constant non-zero value. Also,
120      untangle ptracers_init.F a little.
121    
122    checkpoint57v_post
123    o change dome exp. to use variable viscosity in side-drag terms.
124    o remove all the files from the cfc_offline test since they are now
125      incorporated into tutorial_cfc_offline which has been producing
126      identical results for a few days of testing
127    o add new parameter: sideDragFactor to enable half-slip-side BC
128      and change side-drag S/R to use viscosity from mom_calc_visc
129      (can switch back by setting sideDragFactor=0.); affects results at
130      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
131       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
132    o vorticity & strain are now computed without masking, to account for
133      no-slip-side BC in variable viscosity calculation ; mask is applied
134      anyway later on, before computing advection/coriolis terms.
135    o modify exp4 to test new obcs support for reading from external files
136      and for passive tracers
137    o fix behavior of ptracers_monitor when monitor output is written to a
138      netcdf-file; still not independent of monitor.F (writes in the same
139      file).
140    o change default value of tRef (put a uniform, meaningful value for ocean
141      & atmos) and initialize sRef (was missing, as Martin mentioned).
142    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
143      to be proportional to enstrophy dissipation length.  Thus,
144       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
145      This is now consistent with Smagorinsky and with the manual.
146    
147    checkpoint57u_post
148    o OBCS and PTRACERS: add open boundary support for passive tracers
149      - either use homogenous (pseudo) v.Neumann conditions or prescribe
150        OB-values from file; this is not different from the way theta and salinity
151        are treated
152      - however, Orlanski-radiation conditions are not supported, and the model
153        will stop if you use pTracers and Orlanski at the same time.
154      - beefed up the rountine obcs_external_fields_load: now only those open
155        boundary values are overwritten with values from files for which there
156        are really files, otherwise the OB-fields remain untouched. This makes
157        it possible to use different OBs at different ends of the domain (as
158        with EXF)
159    o reduce number of exch calls in shap_filt (s2).
160    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
161      truncation level) 4/5 MLAdjust test results (11&12 digits match).
162    
163    checkpoint57t_post
164    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
165    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
166      same truncation, independent of the face number: affects affects several
167      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
168    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
169      note that biharmonic viscosity + no-slip was not tested in any experiment.
170    o fix bug in non-linear free-surf side-drag ; generate new output for
171      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
172    o make mnc honor the writeBinaryPrec flag for most kinds of output
173    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
174    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
175      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
176    o add brackets in multi-terms sum to get same truncation, independent of
177      the face number (manage to get exactly same value of gU,gV at the cs-edge)
178      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
179    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
180      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
181      a maximum grid-scale Reynolds number.  Also, changes all length calculations
182      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
183      Suggested values of viscosity parameters found in mom_calc_visc.
184      Many new viscosity diagnostics available.
185    
186    checkpoint57s_post
187    o Add clearing-house for viscosity calculations, mom_calc_visc and
188      correct numerous bugs in LeithD and Smagorinsky discretizations.  
189      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
190      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
191      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
192      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
193      The Strain-Tension form is now called with useStrainTensonVisc=.true.
194      ViscAhStrain and viscAhTension are now retired.
195    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
196    o In response to JMC's bug report, genmake2 now ignores any soft-links
197      that it finds in the *current* directory when searching for files.
198      Soft-links found in any other source directories will still work as
199      they did before.
200    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
201      a C routine to unlimit the stack size
202    o mnc-ify pkg/aim snapshot vars
203    o mnc-ify pkg/land as requested by Daniel
204    o various changes to mnc including:
205      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
206      - output can now be grouped so that all files within a group
207          change the ITER portion of their names in lock-step together
208      - can now read ("global") PER-FACE (in addition to PER-TILE) files
209          and works with both EXCH1 and EXCH2 (but needs more testing)
210      - writing works for all verification test cases w/ g77 on Linux
211    
212    checkpoint57r_post
213    o make MNC variable initialization happen earlier
214    o add diagnostics for (almost) each term of the momentum Eq.
215    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
216    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
217    o remove MINIMAL_TAVE_OUTPUT option ;
218      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
219    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
220      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
221    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
222    o add time-dependent SST, SSS control
223    o cost terms in ecco/ modularized (new cost_generic.F)
224    o cost_averages routines are modularized (new cost_averagesgeneric.F)
225    o new infrastructure for seaice model vs. obs misfits in seaice/
226      * driver from the_main_loop.F is seaice_cost_driver.F
227      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
228      * gradient check in Exp. 6a of natl_box_adjoint/
229    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
230      (see README file)
231    
232    checkpoint57q_post
233    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
234    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
235      - bug was reported by Jean-Michel and Ian Fenty
236    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
237      update exp. cpl_aim+ocn output.
238    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
239      Needed for high-res. runs with large global files
240      to be able to limit tapelev size
241    o Changed some tests for adjoint:
242      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
243      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
244      * global_ocean.90x40x15/ back to default 3-level checkpointing
245    o Modifications to enable scripted COMMON to MODULE conversion
246      * verification/OpenAD/code/ has necessary scripts and description;
247      * converts, compiles and runs successfully;
248    
249    checkpoint57p_post
250    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
251    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
252      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
253    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
254    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
255      (was already the case for dissipation with mom_vecinv,
256       and also the case for grad.PhiHyd when staggered-timeStep)
257      This will allow to put dissipation out-off the AB time-stepping.
258     Unfortunately, affects truncation error. Update output of exp. that "fails"
259      (cg2d matching number) and leave the others for later: front_relax(10),
260      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
261      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
262    
263    checkpoint57o_post
264    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
265      (2) its ready to be documented during the 20050801 DocFest
266    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
267      for ideal_2D_oce and lab_sea on linux_ia32_g77
268    o set to #undef CTRL_SET_OLD_MAXCVARS_30
269      in global1x1_tot/code_seaice_adj to access indices 32, 33
270      (worth another tag)
271    
272    checkpoint57n_post
273    o adding precip control xx_precip 32
274    o adding swflux control xx_swflux 33
275    o Replacing 10 forcing penalty cost routines by 1 generic.
276    o Implementing partitioning in time-mean and variable adjustment
277      for atmos. state.
278    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
279    o in natl_box_adjoint:
280      * updated exp 1 to 10
281        (but does not have time-mean vs. variable split results yet)
282    o updated global1x1/*_seaice_adj/
283      to incorporate latest changes
284    o enable useSingleCpuIO for mdsio vector routines
285      (applies in particular to tapelev I/O)
286    o removed inefficient K-loop in all active_file*control*.F
287    
288    checkpoint57m_post
289    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
290      and advect_cs (use EXCH-2 and standard cs-32 grid files).
291    o pkg/exch2: filling of face-corner halo regions is optional
292      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
293    
294    checkpoint57l_post
295     tag before updating tutorials (pre-release-2)
296    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
297       for output and interpolation of input fields onto model grid)
298    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
299       Affects results of exp. rotating_tank ; update output.txt.
300    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
301          and taking the square quantity and/or using a fraction-weight field.
302    o fix aim_diagnostics_init.F mate numbers.
303    o add mnc output capability to diagnostics/diagstat and update
304      our cvsignore files for the ACSII output generated
305    
306    checkpoint57k_post
307    o lab_sea now uses diagnostics package and provides a suite of
308      new EXF diagnostics output.
309    
310    checkpoint57j_post
311    o exf
312      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
313        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
314        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
315      * extended diagnostics output
316        - now includes all EXF variables
317        - hs, hl moved to common block
318        - separate S/R for diagnostics, called after ctrl vector is added
319        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
320        - EXFqnet contains true Qnet (i.e. includes qsw)
321      * updated verif. lab_sea, global_with_exf
322      * Rearranging hflux (exf_mapfields -> exf_getforcing)
323        to ensure that diagnostics sees a true EXFqnet
324    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
325    o diagnostics pkg: change pointers so that 1 diagnostic can be used
326      several times with different frequencies.
327    o mnc-ify the thsice package as requested by Daniel Enderton
328      - the monitor--MNC output needs work
329      - many attributes need to be added (most are currently blank)
330    o mnc-ify theaim_v23 package as requested by Daniel Enderton
331      - many attributes need to be added (most are currently blank)
332    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
333    o add Sadourny like discretization to the 4th.O vorticity advection scheme
334    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
335      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
336         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
337    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
338     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
339    
340    checkpoint57i_post
341    o Diagnostics package was changed: diagnostic allocation is now deactivated
342      by setting an empty file name in the namelist (used to be by setting 0 frequency)
343    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
344      add 1rst Order upwind vertical Shear.
345    o add a quick fix for A/B checkpointing in OFFLINE mode
346    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
347      end-run around the C/Fortran linking horror in eesup/src/timers.F
348    o added pkg/runclock: allows user to terminate run based on wall clock
349    o added non-hydrostatic scaling parameter: nh_am2
350    o pkg/my82: futile attempt to make results compiler-independent by adding
351      some "_d 0", etc. no effect.
352    o for mnc output, fill the 'T' coordinate var with myTime and create a
353      separate 'iter' variable for iteration count
354    o pkg/diagnostics:
355      add new capability: output of Global/Regional & per-level statistics ;
356      tested against monitor output (including land & thSIce) on various exp.
357    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
358    
359    checkpoint57h_done
360      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
361      data.diagnostics, data.gchem, data.ptracers) is done.
362    
363    o pkg/diagnostics: prepare for Global/Regional statistics.
364      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
365    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
366      and rename it: DIFFERENT_MULTIPLE
367    
368    checkpoint57h_post
369    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
370    o pkg/diagnostics: change output frequency, now in seconds (instead
371      of Nb of iterations). This requires to change data.diagnostics.
372    checkpoint57h_pre
373    
374    o in mnc, let the user create the output dir if both mnc_outdir_date
375      and mnc_outdir_num are false
376    o add fflags() to pkg/diagnostics which allows one to specify, on a
377      per-file basis, the file precision [default behavior is unchanged]
378    o added diagnostics to pkg/kpp, including computation of mixed layer
379      depth based on a temperature/density criterion
380    o updated verification/natl_box to test the new pkg/kpp diagnostics
381    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
382    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
383    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
384      not mnc -- this mistake was found by JMC and is now corrected
385    
386    checkpoint57g_post
387    o add Adams-Bashforth 3rd Order time stepping:
388      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
389      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
390    checkpoint57g_pre
391    
392    o make lambda[Theta,Salt]ClimRelax spatially varying
393      (default remains spatially uniform constant based on tau)
394    o added new control variables
395      * init. uVel, vVel, etanN
396      * lambda[Theta,Salt]ClimRelax
397    o separate masks used for ctrl_pack/unpack 'from write_grid' output
398      (suggested by G. Forget)
399    
400    checkpoint57f_post
401    o add parameter "baseTime" = model base time = time at iteration zero
402      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
403      account for baseTime shift
404    o move Coriolis arrays from PARAMS.h to GRID.h
405    checkpoint57f_pre
406    
407    o mnc-ifying the seaice package
408    o introduced an alternative length scale calculation for use in the limiting
409      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
410    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
411    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
412      as well as grad(vort3).  Made it compatible with both approximate form
413      for the cubed sphere and full form of these gradients.  Added flag
414      useFullLeith to select between approximate and full form.  
415    o add "d0" in getcon.F to reduce differences between compilers/platforms
416      update output.txt of exp. fizhi-gridalt-hs
417    o change port_rand funtion to allow to set the seed.
418    o fix obscure MNC bug involving conversion between reals and integers
419      - it caused no problems with certain (eg. gcc, ifc) compilers but the
420        new version is now more standards-compliant
421    o adjoint-related modifications
422      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
423      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
424      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
425    
426    checkpoint57e_post
427    o Adding eddy stress controls a la Ferreira et al.
428    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
429    
430    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
431      update output.txt of exp. fizhi-gridalt-hs
432    o add more "Z" dimensions and associated coordinate vars to MNC
433    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
434    o parameter calendarDumps: when set, approximate months (30-31 days) and years
435      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
436      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
437      months and years.  Requires pkg/cal.
438    o diagnostics: add pickup functionality
439      - off by default for backwards compatibility
440      - current version only uses MDSIO -- MNC will be added
441    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
442    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
443    
444    checkpoint57d_post
445    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
446    o modify verification/ideal_2D_oce so that it tests the creation of mnc
447      output from the diagnostics package
448    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
449    o make genmake2 more portable by using ".$FS" instead of ".f" for more
450      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
451    o add coordinate variables to the MNC output from the diagnostics package
452    o change MNC-flags default value: true when useMNC=TRUE
453    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
454      the ability (off by default) to read the grid information using MNC
455    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
456    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
457    o do snap-shot diagnostics at the middle of the time-interval (instead of
458      at the end).
459    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
460      new test for AIM with thSIce + slab-ocean
461    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
462    o move state variable diagnostics to the beginning of the time step ;
463      (note: still needs some work specially for snap-shot diagnostics)
464      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
465    
466    checkpoint57c_post
467    o Change testing option (-ieee) to get closer agreement between g77 & ifort
468    o generate new output.txt files on faulks with g77 & the new -ieee option
469    checkpoint57c_pre
470    
471    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
472      update output.txt of exp. global_ocean.90x40x15
473    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
474      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
475    o add saltFlux(+File) forcing capability with periodicExternalForcing
476    o allow to use pkg diagnostics for GM-Redi & ThSIce output
477    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
478    o improvements for the MNC output from DIAGNOSTICS:
479      - correct handling of the unlimitied dimension
480      - all dims now have associated coordinate variables
481      - variables located at U, V, and Corner ("Z") points are now written
482        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
483        *all* data points are output
484    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
485    o added pkg/seaice/seaice_monitor.F
486    o mdsio_readfield.F can now read files visible only to master MPI process.
487    o pkg/seaice: some test code for ice-modified ocean stress
488    o exf_getffields interpolation defaults to bilinear for all scalar forcing
489      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
490      spurious negative numbers for precipitation and humidity.  Will cause
491      some small numerical differences for integrations using pkg/exf/exf_interp.F.
492    o pkg/ctrl/
493      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
494        May be enabled via doPackDiag
495      *  introduce z-scaling of
496         + gradient (doZscalePack) and
497         + control (doZscaleUnpack)
498    o pkg/mdsio/
499      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
500      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
501    
502    checkpoint57b_post
503    o simplify options in diagnostics_fill arguments (remove weird combinations)
504    o fix MNC coordinate variables so that they now contain per-face index
505      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
506      general, EXCH2 grids are only aligned to a "local" coordinate system
507    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
508    o Implement instantaneous output within pkg diagnostics:
509      setting a negative frequency in data.diagnostics produces
510     "snap-shot" output (as opposed to time-average if freq > 0)
511    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
512      NOTE: change ptracer diagnostics name: use 2 characters to work with
513            more than 9 tracers. Add also diagnostics of advect & diffus flux.
514    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
515      becomes the coordinate variable for the 'T' dimension
516    o add CF-style coordinate variables to MNC
517      - just a first cut:  numbers are meaningless on the cubesphere and
518        missing along the T axis but otherwise it works!
519    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
520    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
521    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
522      this is based directly on what the model compute, so that the content of
523      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
524    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
525    o clean up build options files for SunOS, in particular
526      - remove -traditional from xmakedepend
527      - change -xarch=v9 to -xarch=native for f77
528      - restore use of make (not gmake)
529      - add CC=gcc if using g77
530    o changes per discussion of AM, JMC, & EH3 today:
531      - move redundant "grid" variables out of "state" -- in preparation of
532        creating proper CF-style coordinate variables and in recognition
533        that any/all grid variables can be easily copied (eg. w/NCO) from
534        the grid files into any of the other NetCDF files
535      - *always* output grid variables with MDSIO (this will eventually be
536        changed)
537      - output MNC grid file if useMNC is true
538    o every instance of _END_MASTER() has been found and replaced with
539      _END_MASTER( myThid ) in order to satisfy certain picky Sun
540      preprocessors
541    o re-arrange diagnostics pkg initialisation:
542     - allow each package to extend the available diagnostics list
543     - add some checking and fix small problems (multi-threaded, ...)
544     - new S/R diagnostics_fill (replace fill_diagnostics):
545       look through the short list of active diag. (instead of the long list)
546       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
547    
548    checkpoint57a_post
549    o this set of changes restores TAMC compatibility
550      tested for global_ocean.90x40x15 adjoint on trough
551      (what a pain)
552    
553    checkpoint57a_pre
554    o some modifs in tools/build_options for sunos
555    o call ctrl_pack for ctrl at end for optimcycle=0
556    
557    checkpoint57
558    o add horizontal bi-harmonic viscosity for vertical velocity
559      - new parameter viscA4W (defaults to viscA4)
560      - affects only non-hydrostatic code
561      - to be done: no-slip lateral boundary conditions
562    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
563    o implement Implicit Vertical advection for pTracers
564    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
565      (implemented also for implicit vertical diffusion & advection)
566    o OBCS: extend application of tracer open boundary conditions
567      to a strip beyond the boundary of width Olx/Oly
568    o add call monitor to TAF set of required calls (flow directives)
569      and include in natl_box_adjoint
570    o untangle a few ifdefs related to cost, ctrl, autodiff
571      untangel a few ALLOW_ECCO_OPTIMIZATION
572    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
573      (theta2, salt2 in ecco_cost_weights)
574    
575    checkpoint56c_post
576    o OBCS as control variables
577      - update ctrl_ad_diff.list, obcs_ad_diff.list
578      - remove balance of obcs controls from default
579      - fix index bug nobcs in ctrl_init
580      - fix dummy fields filen in ctrl_pack
581      - add dummy weights for obcs
582    o lsopt: comment out fort.94 output
583    o optim:
584      - remove unnecessary header files
585      - adjusted namelists
586      - add xerbla.F to Makefile
587    o exf:
588      - multiple modifications of exf_check_range
589      - unit change in exf_init_runoff from [m/year] to [m/s]
590    o mdsio:
591      - i/o-vector change debugLevel from debLevA to debLevB
592    
593    checkpoint56b_post
594    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
595      is called from DO_THE_MODEL_IO
596      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
597      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
598      - clean up PTRACERS_WRITE_TIMEAVE a little
599    o add another verification experiment that tests both the cfc-pkg and
600      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
601      reactive tendencies treated inline with regular timestepping
602    o testreport previously did a lousy job of comparing small numbers, so
603      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
604      implemented in the little c-progam tmp_cmpnum.c which is embedded in
605      testreport.
606    o ptracers_monitor: bug fix for MPI
607    
608    checkpoint56a_post
609    o GCHEM: finish reorganizating the package
610      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
611        (introduces another 3D-array for each passive tracer, but only if
612        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
613        gchemTendency is not needed because the timestep is done separately)
614      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
615      - GCHEM is now---more or less cleanly---separate from PTRACERS
616      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
617        so clear to me how that should be done in a general way.
618    o CFC: improve formatting of output in CFC_ATMOS
619    o PTRACERS:
620      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
621        that ALL experiments with ptracers enable can be checked. This makes
622        GCHEM_MONITOR obsolete.
623      - include a runtime parameter PTRACERS_monitorFreq that defaults to
624        monitorFreq
625      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
626    o add PTRACERS (PTR0[1-5]) to testreport output
627    o exf_check_range:
628      * default changed to .TRUE.
629      * will check values for niter0 if debLevA, every timestep if debLevB
630      * STOP in exf_check_range if 'out of range'
631      * range chosen generous to allow for potential extema
632      TBD: a version with stricter range
633           permitted range would be runtime parameters
634    o GMredi:
635      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
636      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
637      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
638    o GCHEM:
639      - move call to GCHEM_FORCING_SEP, so that it is now called before
640        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
641      - introduced a useGCHEM runtime flag and applied it everywhere.
642      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
643        this flag is now only visible within GCHEM-pkg routines.
644      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
645        be replaced by a 3D array that is computed before thermodynamics; for
646        this, the tracer ID iTracer had to be included into the parameter list
647        of ptracers_forcing
648      - set up forward_step to call gchem_forcing, that will replace
649        gchem_forcing_int in ptracers_forcing
650      - cleaning up
651    o small cleaning of exch2: remove files that are also in eesupp/src
652    
653    checkpoint56
654    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
655    o mnc: cleanup "full" files--fixes out-of-memory problem
656    o ECCO-GODAE
657      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
658      * fully merged and updated from SIO code
659        windstress sign change affects
660        - exf_inscal_[u/v]stress
661        - sign of xx_tau[u/v] adjustments
662        - signs in cost_scat
663      * ctrl_get_gen: avoid update of tau[u/v] for first few days
664      * natl_box_adjoint updated and compressed
665      * 2-level checkpoint switch added
666        (tested in EXP. 1 of natl_box_adjoint)
667      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
668    o SVD
669      * first complete, non-hacked version for SVD calculations
670      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
671        performed via direct access files admtlm_vector.it????
672        (via ctrl_[un]pack)
673      * optimcycle is used for ARPACK iteration counter
674        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
675      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
676        and add linear transforms where necessary
677      * controls are initial/final SST, SSS (can be extended; need to check
678        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
679    o mdsio: filename info to both stderr, stdout
680    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
681      from sign change
682    
683    checkpoint55j_post
684    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
685      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
686    o add consistent build directories and .cvsignore files to verification
687    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
688    o make all subroutines 30 or less characters in length for certain older
689      compilers to work (a thorough search only turns up two routines in
690      pkg/ptracers)
691    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
692      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
693    
694    checkpoint55i_post
695    o change arrays for total vertical diffusivity (2.D if explicit,
696      3.D if implicit) ; each ptracer uses its own background value.
697    o added mnc/NetCDF output capability to ocn_compon_interf
698      - added bits to verification/cpl_aim+ocn so that it can run on
699        ITRDA and other clusters without the mpirun "-wd" option
700    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
701      configuration
702    o give MNC the ability to create additional files rather than
703      exceeding a specified file size limit "MNC_MAX_FILESIZE"
704      - the default is just less than 2GB which is a practical limit
705        on many systems
706    o Compute the non-local term using either KPP vertical diffusivity (=default)
707       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
708    
709    checkpoint55h_post
710    o add verification test "vermix"
711    o remove all the *_ioinc flags and replace with the single global
712      outputTypesInclusive flag
713    o allow to set a vertical profile of vertical diffusivity for T & S
714    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
715    o useMNC moved from data.mnc to data.pkg
716    
717    checkpoint55g_post
718    o Renaming carbon AD experiments to comply with testreport conventions
719    o Updating adjoint of Held-Suarez hs94.1x64x5
720    o Fixing directives for non-ECCO forward_step, after ECCO directives
721      have been fixed to avoid recomp. of do_oceanic_phys
722      Works well for global_ocean.90x40x15,
723      but recomp. issue remains for carbon
724    o Updating adjoint output for natl_box_adjoint after
725      pkg/ecco has been modified (see taga c55d_post)
726    
727    checkpoint55f_post
728    o rename to timeave_init_fixed
729    
730    checkpoint55e_post
731    o some delicate re-shuffle of store directives to avoid one
732      extra call of do_oceanic_physics
733      affects ecco_the_main_loop.F, do_oceanic_physics.F
734      checkpoint_lev1_directives.h
735    o NB: this may break global_ocean adjoint temporarily,
736      but it is clear how to fix it. Will do later, need this now.
737    
738    checkpoint55d_post
739    o ECCO specific cost function terms (up-to-date with 1x1 runs)
740    o ecco_cost_weights is modified to 1x1 runs
741    o modifs to allow observations to be read in as
742      single file or yearly files
743    o enable to read exf forcing fields as either
744      single file or yearly files (flag useExfYearlyFields)
745    checkpoint55d_pre
746    
747    o switch between 2-level and 3-level checkpointing
748    o add ability of MNC to write local and "partial" (eg. 2D slices where
749      the full 3D field is never actually stored) arrays to NetCDF files
750      with the correct (that is, the complete multi-dimensional) set of
751      array indicies
752      - used in mom_vecinv() to write the diagFreq output
753      - tested (demonstrated) in verification/aim.5l_cs
754    o further mnc-ification
755      - add verification/lab_sea to the list with mnc setups
756      - fix undefined mnc v-names in cd_code
757      - add kpp to mnc output (both snapshot and timeave)
758    o non-hydrostatic code
759      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
760        in calc_gw.F
761      - defaults to viscAh
762      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
763        friction or Leith) in non-hydrostatic mode, as long as there is
764        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
765    o pkg/cost
766      extend simple cost functions to treat time mean quantities
767      (T,U,V) via cost_accumulate_state from cost_tile
768    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
769        be 2 times larger than the minimum size the advection scheme requires.
770        now get a perfect conservation of salt in advect_cs test-exp (updated)
771    o GGL90 (Gaspar's TKE mixed layer)
772      - add horizontal diffusion of TKE, requires exchanges in
773        do_fields_blocking_exchanges, horizontal diffusivity is zero by
774        default. In OPA there is no horizontal diffusion of TKE but the
775        mixing coefficients are computed from a horizontal average of TKE of
776        6 points or so. I think that diffusion has a little more physical
777        justification.
778      - clean up ggl90_calc in the hope of reducing memory usage (this hope
779        was in vain)
780      - mask tke-variable in ggl90_init
781    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
782    o fix biharmonic diffusion on CS-grid.
783    o more obcs stuff
784      - added obcs_external_fields_load as an alternative to the EXF-pkg option
785        for reading boundary values. This routine is called from
786        obcs_prescribe_read
787      - updated obcs_check
788      - changed sponge layer relaxation parameter units for days to seconds
789      - turned off sponge layer by default
790      - changed argument list of OBCS_CALC to myTime+deltaTclock
791      - fixed about 35 bugs in obcs_external_fields_load
792    
793    checkpoint55c_post
794    o obcs stuff
795      - new runtime flags useOBCSprescribe, useOBCSbalance
796      - re-arranged obcs_calc
797      - moved exf_getobcs to obcs_prescibe_read
798        obcs_prescibe_read is called after ORLANSKI stuff
799        and independent of it (executable can contain all).
800      - updated obcs_check
801      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
802        These may be necessary only if tangential velocities are
803        prescribed at OB, not sure, needs testing.
804    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
805      which simplifies the calls and passes the ifc check-bounds test
806    
807    checkpoint55b_post
808    o add a 2D scalar, Z location, exchange_2 routine.
809    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
810      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
811      affects advect_cs results (for the wrong reason): update output.txt
812    o use a more standard discretization for biharmonic viscosity ;
813     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
814      affects results of dome set-up: update output.txt
815    o fix gad_advection.F (CubedSphere part), back to version 1.23
816    o fix bug in mom_vi_del2uv.F (CubedSphere part).
817    
818    checkpoint55a_post
819    o merged code to
820      * prescribe/read time-dependent open boundaries
821        (works in conjunction with exf, cal)
822      * sponge layer code for open boundaries
823      * each boundary N/S/E/W now has its own CPP option
824        (healthy for the adjoint)
825    
826    checkpoint55
827    o up-to-date adjoint of previous breaks
828      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
829      - global_ocean_ebm: adjoint still needs fix (TLM ok)
830      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
831      - carbon: * remove tr1-related adjoint verification
832                * add ptracer as control variable
833    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
834      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
835    
836    checkpoint54f_post
837    o in verification/carbin/ remove experiment related to
838      ALLOW_PASSIVE_TRACER (array tr1 etc)
839      code_ad/ input_ad/ results_ad
840    
841    o add two new packages
842      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
843        + subject to optimization (memory)
844      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
845        + subject to reordering (many GOTOs in the original code)
846        + so far opps is called for every (i,j) point, and then operates in
847          the vertical; one may want to reorder the scheme in order operate in
848          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
849          fields)
850    o overhaul of IO so that we now have flags for MDSIO and/or MNC
851      - all verification tests compile and run with linux_ia32_g77
852      - defaults are compatible with current input files--nothing
853        should change if you were not previously using MNC
854      - MNC output has been added in numerous places (eg. timeave)
855        but there are still a few writes not yet do-able with MNC
856        (this is in progress)
857      - flags now allow for either/or/both use of MDSIO and MNC and
858        documentation will soon follow
859      - numerous small formatting cleanups for ProTeX
860    o add version info (via BUILD_INFO.h) to MNC and stdout
861    
862    checkpoint54e_post
863    o add two new packages
864      - pp81 (Packanowski and Philander, 1981), Richardson number and
865        stratification dependent mixing
866      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
867      - these scheme operate in a similar manner as KPP (without ghat, of
868        course), however there is only one diffusivity that is used for both
869        temperature and salinity (and passive tracers)ç
870    o add offline package
871    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
872      provided by Stephanie Dutkiewicz
873    o genmake2: add ability to search for C compilers and cleanup test output
874      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
875    
876    checkpoint54d_post
877    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
878    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
879      leading to additional shift by 5 days each year of integration
880       (i.e. leading to considerable offset over the years)
881    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
882    o start with no AB and no initial filtering (staggerTimeStep):
883      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
884    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
885      (external loading & cpl import/export stay in forward_step.F)
886    o update coupling interface to work with new staggerTimeStep
887    o change MDSIO ptracers_pickup.
888    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
889    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
890    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
891    
892    checkpoint54c_post
893    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
894      this affects (truncation error) output.txt of test-exp:
895       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
896    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
897    o change Qnet to always be the net heat flux, (+upward).
898      affects (truncation error) output of natl_box exp.: updated
899    o define the max number of passive tracers in PTRACERS_SIZE.h
900    o start to test mnc routinely in exp0
901    o add sea-ice loading (sIceLoad) as a new forcing field.
902    
903    checkpoint54b_post
904    o add testreport "-j JOBS" option for parallel builds (tested and pretty
905       impressive on Altix and Opteron systems)
906    o diagnostics can now write NetCDF files through the mnc package
907    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
908    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
909    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
910      affects (truncation error) output of lab_sea & natl_box exp.: updated
911    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
912    
913    checkpoint54a_post
914    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
915    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
916    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
917    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
918      + internal_wave (shift in writing cg2d_ini_res)
919    checkpoint54a_pre
920    
921    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
922      - modified verification/lab_sea and natl_box_adjoint accordingly
923    
924    checkpoint54
925    checkpoint53g_post
926    o prepare splitting of thermodynamics: store convect.counter in common block
927    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
928      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
929    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
930    o new parameter "nShapS": allow to treat differently S from T (nShapT)
931    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
932    o restore adjointability
933    
934    checkpoint53f_post
935    o modifications that affect AIM experiment results (update output.txt):
936      - no advection of S at top interface Nr (pkg/generic_advdiff)
937      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
938    o AIM pkg:
939      - include stability function into surf.Flux derivative relative to Tsurf
940      - calculate clear-sky radiation & surface temp. change (for diagnostics)
941    
942    checkpoint53e_post
943    o merged cylindrical coord configuration
944    o added rotating_tank experiment
945    checkpoint53e_pre
946    
947    checkpoint53d_post
948    o faulks upgraded: re-generate output.txt that have changed:
949       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
950    o Added Bryan and Lewis, 1979, vertical diffusivity profile
951    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
952    o added Sadourny discretization of Coriolis
953      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
954      - re-enabled use of omega3 (useAbsVorticity)
955    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
956      vector-invariant equations
957      - note: does *NOT* yet use same variable visc. for no-slip BC's.
958    o recoded the lateral boundary conditions for non-hydrostatic w, this time
959      hopefully without new bugs
960      - still to do: biharmonic friction for non-hydrostatic w
961    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
962    o regenerated output for global_ocean_ebm (using -ieee)
963    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
964      of mom_common/
965      - simple re-arrangement of instructions within computing loop
966    checkpoint53d_pre
967    
968    checkpoint53c_post
969    o new version of coupler for AIM+thSIce and Ocean models
970     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
971     - land: change Evaporation of snow
972     - aim with thSIce: fix bug in snow-precip.
973    o changes to calc_gw.F
974     - bug fix for w^2 term near the bottom boundary
975     - (hopefully) improve the lateral slip boundary condtions for use with
976        partial/looped cells
977      - because the bug fix changes two verification experiments anyway (exp5
978        and plume on slope), change the lateral boundary condition from half slip
979        to the value of no_slip_sides
980    o ebm package wasnt quite up to the parallel task. Fixed that.
981    o Adjoint of EBM package + verification
982      * TLM OK
983      * ADM not sufficient accuracy yet (needs further testing)
984    
985    checkpoint53b_post
986    o Commiting new energy balance model to repository
987      * package is pkg/ebm
988      * verif. is verification/global_ocean_ebm
989      * references are in ebm_driver.F
990    C      * X. Wang, P. Stone and J. Marotzke, 1999:
991    C        Global thermohaline circulation. Part I:
992    C        Sensitivity to atmospheric moisture transport.
993    C        J. Climate 12(1), 71-82
994    C      * X. Wang, P. Stone and J. Marotzke, 1999:
995    C        Global thermohaline circulation. Part II:
996    C        Sensitivity with interactive transport.
997    C        J. Climate 12(1), 83-91
998    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
999    C        Destabilization of the thermohaline circulation
1000    C        by atmospheric eddy transports.
1001    C        J. Climate 7(12), 1870-1882
1002    o Will need long integration testing.
1003    checkpoint53b_pre
1004    
1005    o created pkg/mom_common in preparation for variable viscosity code
1006    o renamed and split ini_mnc_io
1007    o pkg/land: only liquid water can diffuse or run-off
1008    o AIM using land: soil wetness availability account for snow
1009    o added printMapIncludesZeros to EEPARMS namelist
1010    
1011    checkpoint53a_post
1012    o restore TAMC compatiility for exf_constants.h
1013      (no usage of _d in .h)
1014    o Additional storing in KPP in an attempt to fix
1015      TAMC problem with adjoint of KPP code.
1016      (no success...)
1017      Identical code works fine with TAF.
1018    o Fixed verification/natl_box_adjoint experiments.
1019      Initial conditions for Experiments 4 and 5 are now
1020      set to "SEAICE_initialHEFF=0", which is more reasonable,
1021      and hence gives results closer to that of Experiment 2.
1022      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1023    
1024    checkpoint53
1025    o stable checkpoint with up to date adjoint
1026      TLM tests only run for 1st grdchk at the moment. Its unclear if
1027      this is a code problem or a problem with resetting code for g_
1028      variables that is being autogenerated wrong.
1029      Otherwise:
1030       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1031       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1032         are both still in chaos following their security messes.
1033    
1034    checkpoint52n_post
1035    o various build (mostly genmake2) changes including:
1036      - ability to build/run more easily within Cygwin and MacOS X
1037      - more complicated Makefiles with a stronger dependence on Gnu Make
1038    o pkg/seaice modifications
1039      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1040        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1041        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1042      - changed proxy for geostrophic velocity and updated
1043        verification/lab_sea/results/* accordingly
1044      - removed ADI dynamic solver from pkg/seaice
1045      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1046        they caused a segmentation fault under certain circumstances
1047      - removed unused field WATR
1048    o bug fix in exf-package:
1049      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1050         now reflect that.
1051    o small fixes in the cal-package:
1052      - set reference date to first of January for the 'model'-calendar
1053      - failing of cal_CheckDate in cal_FullDate now actually results in a
1054        warning
1055    o small modifications in exf-package to increase flexibility:
1056      - change climtempfreeze from a constant to a runtime parameter that
1057        is specified in data.exf_clim (default = -1.9)
1058      - introduce runtime parameter windstressmax (default = 2.0) that is
1059        specified in data.exf
1060    o fix in pkg/thsice:
1061      - update Evap (Tsf changes) to be consistent with Latent heat flux
1062      - maintain snow precipitation unchanged (even if Tsf >=0).
1063     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1064    
1065    checkpoint52m_post
1066    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1067      this does not change any of the results, because myIter=0 in swfrac always
1068      lead to jwtype=2 (the default anyway), but the call makes little sense
1069      as a default
1070    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1071    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1072      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1073    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1074    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1075    o extending useSingleCpuIO option to work with new exch2 I/O format
1076      - old-style, missing-tile I/O is still accessible by defining CPP
1077        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1078    o monitor package can write to NetCDF files and/or STDOUT
1079    o fix re-definition bug in MNC_GRID_INIT_ALL()
1080    o doc/api_reference added
1081      - a framework for building an API Reference Manual using all
1082        the "protex" comments embedded in the code
1083      - see pkg/generic_advdiff, pkg/mnc for examples
1084    o MNC:
1085      - make myThid the last argument for all subroutines
1086      - new default for the grid files: NO halos
1087      - add useMNC and other run-time flags
1088      - separate per-file-group handling of the unlimited dimension
1089      - early initialization of MNC w/ flags read at the eeboot stage
1090        and lookup tables set in initialize_fixed
1091      - write all MNC output to a freshly-created directory
1092    o thermodynamics sea-ice (thsice) is now tested with testreport.
1093    o test exp. advect_cs: use the standard cs32 grid ; update output.
1094    o Added functionality to grdchk:
1095      pick global i,j,k position (or nearest wet) where to perform check.
1096    
1097    checkpoint52l_post
1098    o new land formulation:
1099      a) use ground enthalpy as prognostic variable to ensure exact
1100         energy conservation.
1101      b) account for water temperature and for latent heat of freezing
1102         in all processes (rain, run-off, ground storage)
1103      c) compute surface and ground temperature implicitly.
1104    o aim_v23 modification for new land model:
1105      a) Treat separately land / ocean / sea-ice surface fluxes
1106         to allow implicit computation of land & sea-ice surface temp.
1107      b) add snow precipitation.
1108    checkpoint52l_pre
1109    
1110    o fix problem (when 1 tile is empty) in min/max monitor.
1111    o fix bug in timeAve (u,vZetatave in common block)
1112    o no restoring terms under ice for pkg/seaice
1113    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1114    o bug fix for pkg/seaice pickups
1115    o change MNC call locations and add coordinate attributes
1116    o mask vorticity at the corner ; affects global_ocean.cs output
1117    o fix ini_curvilinear_grid ; test CS experiments with mpi
1118    o aim.5l_cs: modify sea-ice fraction input file ; update output
1119    o exf: Adding simple range check routine for exf fields after read
1120    
1121    checkpoint52k_post
1122    o removed top-level directory "diags"
1123      - we migrated these functions to pkg/timeave a long time ago
1124    o fixed bug introduced in pkg/monitor
1125    o accuracy ctrlprec = 32 insuffient for gradient checks using
1126      averaged fields (I/O via cost_averages)
1127      -> use ctrl.h in active_file*.F to control I/O precision.
1128    o paramter list of CALL ADTHE_MAIN_LOOP
1129    o added initial do_the_model_io to ecco
1130    o set all ...Freq to zero after cost_final
1131      taveFreq, dumpFreq, pChkptFreq
1132    o MAIN and ECCO differentiability restored
1133    
1134    checkpoint52j_post
1135    o fix nchklev in tamc.h for global_ocean...
1136    o Bringing flow and store directives up-to-date
1137    o Really weird thing!
1138      call do_the_model_io from the_main_loop with parameters
1139      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1140      TAF places a faulty re-call of initialise_varia
1141      after cost_final call which should not be there!
1142    checkpoint52j_pre
1143    
1144    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1145      error messages
1146    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1147    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1148      debug output
1149    o modfied mdsio_writefield.F to handle non-global files under exch2
1150    o update AIM Cubed-Sphere exp (aim.5l_cs):
1151      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1152    o update AIM Equatorial Channel exp:
1153      use standard aim_v23 pkg and change the SST fields to be more realistic.
1154    o globalFile now works with exch2
1155    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1156      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1157    o limit timeave output for hi-res integrations
1158    
1159    checkpoint52i_post
1160    o removed CPP_EEOPTIONS.h from verification/*/code
1161    o updated the tiling for global_ocean_pressure
1162    checkpoint52i_pre
1163    
1164    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1165      the old pkg/aim).
1166    
1167    checkpoint52h_pre
1168    o shortened offending lines in exch2_send_rx?.template
1169    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1170    o genmake2: add build & execute test for NetCDF code
1171    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1172      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1173    o added useSingleCPUIO flag to monitor.F and mon_out.F
1174    o added temporary hack for sea-ice dynamics on the cube:
1175      metric terms are ignored and it is assumed that
1176      there is no sea-ice on cube faces 1, 2, 4, and 5.
1177    
1178    checkpoint52f_post
1179    o added exch2 cube routines to pkg/exch2
1180    o modified hs94.cs-32x32x5 to use it
1181    o added new grid files to hs94.cs-32x32x5
1182    checkpoint52f_pre
1183    
1184    checkpoint52e_post
1185    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1186      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1187    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1188      to work with implicit vertical advection and AB ;
1189    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1190    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1191     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1192    checkpoint52e_pre
1193    
1194    o fix bug in impldiff when Nr=1 or Nr=2.
1195    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1196    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1197    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1198      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1199    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1200    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1201    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1202    
1203    checkpoint52d_post
1204    o re-tiled many expts to allow comparison in multi-processor mode
1205      - updated output accordingly
1206      - changed hs94.128x64x5 to use intial T from file rather than use the
1207        random number generator
1208    o add infrastructure in model routines for fizhi and gridalt packages
1209    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1210    o changes to permit hi-res, cubed-sphere, configuration
1211      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1212      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1213      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1214        of surface winds for the cube
1215      (A verification experiment, based on global_ocean.cs32x15, but with
1216       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1217       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1218       complete with example surface forcing files and matlab scripts to look
1219       at the output and compare it with that of global_ocean.cs32x15.)
1220    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1221       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1222       to conform to the common rule.
1223    o check-in the first version of the coupler + interfaces for multi-components
1224       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1225       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1226       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1227       - ocean and atmos. share the same horizontal grid (no interpolation).
1228       - exchanges between component and coupler is done in forward_step
1229    o new verification experiment, cpl_aim+ocn:
1230       coupled ocean - AIM atmosphere on cs32 grid.
1231    
1232    checkpoint52d_pre
1233    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1234    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1235    
1236    checkpoint52c_post
1237    o Fixing OPTIONS files for use of exf:
1238      - ALLOW_ECCO not needed
1239      - ECCO_CPPOPTIONS.h should not be included from
1240        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1241        as has been the case in the past
1242      - All cal/exf related options are currently set in
1243        single header file. Should remain so until we
1244        agree on a consistent new policy.
1245    o Removed all CPP options for cal package.
1246      cal has no more CPP options.
1247    o modified STOREs in GAD_ADVECTION
1248    o corrected key comp. for passkey
1249    
1250    checkpoint52b_post
1251    o new version: "thsice" of thermodynamic sea-ice pkg:
1252     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1253     - modify fluxes but do not change theta directly;
1254     - light cleaning of bulk_force pkg (still needed with thsice).
1255     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1256       + output_thsice.txt to test thsice & bulk_force pkgs.
1257    o put back grid & coriolis monitor output.
1258    checkpoint52b_pre
1259    
1260    o call "do_the_model_io" at the beginning (=> dump initial state)
1261    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1262    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1263      (need info on NUMBER_OF_PTRACERS)
1264    o missing PTRACERS headers in some routines
1265    o default tamc.h in pkg/autodiff supposed to crash
1266      to ensure proper customization
1267    
1268    checkpoint52a_post
1269    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1270      - moved surfaceTendencyTice from pkg/seaice to main code
1271      - subroutine FREEZE_SURFACE now limits only surface temperature
1272        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1273        => new output.txt for global_ocean.cs32x15 & global_with_exf
1274      - keep the old version of FREEZE for backward compatibility;
1275        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1276      - corresponding modifs for TAF directives
1277    o added surface flux output variables to TIMEAVE_STATVARS
1278    o time-averaged output for pkg/ptracers
1279    o fix problem with ECCO-related divided adjoint
1280      snapshot file was missing some ad-variables,
1281      but no warning issued by TAF
1282    
1283    checkpoint52a_pre
1284    o some bug fixes for #undef REAL4_IS_SLOW
1285    
1286    checkpoint52 = ecco_c52_e35
1287    o after testing adjoints of checkpoint51u_post
1288    
1289    checkpoint51u_post
1290    o this is the post-merge tag of the ecco-branch
1291      (needs another clean checkout and re-testing)
1292    o various natl_box_adjoint configs and results
1293      but no input fields
1294    o obcs adjoint not yet merged!
1295    o adding ECCO global 1x1 and 2x2 degree configs
1296    o updated/extended some store directives for seaice
1297    o pkg/ecco now containes ecco-specific part of cost function
1298    o top level routines the_main_loop, forward_step
1299      supersede those in model/src/
1300      previous input data.cost now in data.ecco
1301      (new namelist ecco_cost_nml)
1302    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1303    
1304    checkpoint51t_post
1305    o this is the pre-merge tag of the ecco-branch
1306    
1307    checkpoint51s_post
1308    o cleanup: removed various obsolete #define-s
1309    o pkg/grdchk
1310      - renamed 'ph-grd 3' to 'grad-res'
1311      - merged from ecco-branch
1312        (remaining bug fixes for obcs gradient checks)
1313      - additional high-precision output for testreport
1314        (grep for 'precision_grdchk_result')
1315    
1316    checkpoint51r_post
1317    o cleaned up or removed CPP_OPTIONS.h files
1318    o updated results for some of the tests to reflect the new
1319      optfiles (-ieee: -O0 instead of -O3)
1320    
1321    checkpoint51q_post
1322    o cd_code:
1323      - moved cd_scheme.F -> cd_code_scheme.F
1324      - separate read_checkpoint from cd_code_ini_vars.F
1325      - separated cd_code part from write_checkpoint
1326      - updated AD_SOURCE, generated .flow
1327      - added CD_CODE_VARS.h to the_main_loop
1328      - Moving cd_code specific store dir.s to pkg/cd_code
1329    o ctrl package totally restructured
1330      - pack/unpack now optional and decoupled from
1331        xx_/adxx_ I/O
1332      - ctrl_pack/unpack cleaned
1333        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1334      - confined inclusion of AD_CONFIG.h to where necessary.
1335    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1336    
1337    checkpoint51p_post
1338    o create initial cd_code package
1339      - WARNING: the initialization of fields within packages
1340        is broken because INI_FIELDS (where READ_CHECKPOINT is
1341        called) is called *before* PACKAGES_INIT_VARIABLES.
1342        This seems to be backwards since
1343        1) its important to initially zero the entire field including
1344           the "halo" region
1345        2) zeroing needs to be done *before* reading pickup info
1346           and the pickup call might or might not happen in any
1347           particular run
1348      - this needs an overhaul for R2
1349    o cleanup verification/*/code/GMREDI_OPTIONS.h
1350    o cleanup testreport
1351    
1352    checkpoint51o_post
1353    o bringing AD-related verif's up to date with genmake2
1354      - carbon/
1355      - global_ocean.90x40x15/
1356      - hs.94.1x64x5/
1357      - (front_relax/ )
1358    o (more) consistent directory structure for AD-related verif.'s
1359    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1360    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1361    o bug fix in find_alpha.F for MDJWF:
1362      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1363        change rho -> rho-rhoConst
1364      - replace call find_rho to find_rhonum
1365    o initialisation of rFlx extended to full array (required by TAF)
1366      and shifted to thermodynamics
1367    o removed PTRACERS.h in ptracers routine
1368    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1369    o Correcting initialisations for fVerU, fVerV.
1370    o helping TAF to recognize dependency on kUp for
1371      fVerU, fVerV
1372    o Replacing delZ by delR in pkg/ctrl/
1373    checkpoint51o_pre
1374    
1375    o undid all of cp51 pending some cleanups and discussion
1376    o added the [#include "AD_CONFIG.h"] statement to all files that need
1377       it for adjoint/tl #defines
1378     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1379     o removed tools/genmake since it no longer works
1380    
1381    checkpoint51n_post
1382    o modifications to make FREEZE flux visible to pkg/kpp
1383      - moved surfaceTendencyTice from pkg/seaice to main code
1384      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1385      - subroutine FREEZE now limits only surface temperature
1386        (this means new output.txt for global_ocean.90x40x15,
1387         global_ocean.cs32x15, and global_with_exf)
1388    o added surface flux output variables to TIMEAVE_STATVARS
1389    
1390    checkpoint51n_pre
1391  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1392  o added [#include "AD_CONFIG.h"] to all files that use the following  o added [#include "AD_CONFIG.h"] to all files that use the following
