4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
9        of LSR (this change is expected to change the results slightly because now
10        it uses slightly difference moduli from the second last LSR solution, but
11        that is more consistent with the stress computations; this part of the code
12        is not tested in the verification experiments)
13      - fix diagnostics for flux of ice in case of B-grid
14      - turn strain rates eij and press into global fields within global
15        common block in SEAICE.h for more straighforward diagnostics
16      - fix diagnostics for principal stress components, press, zeta, eta
17        to give something meaning full
18    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
19      new output (all 4 tests) using default rotationPeriod.
20    o pkg KPP:
21      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
22      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
23        and normal grid from 1 to Nr)
24    o Fix computations of L4rdt in mom_calc_visc.F
25    o eesupp:
26      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
27      should be called before a "stop" if we know that all process are going
28      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
29    
30    checkpoint61o
31    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
32    o model/src/ini_curvilinear_grid.F:
33       compute angleSin/CosC when they are not read from a file
34    o pkg/seaice:
35       add pseudo time stepping for LSOR
36    o pkg/exch2:
37       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
38    o pkg/seaice:
39       Adding separate sea ice albedo, drag coefficients, and HO in Southern
40       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
41    o SingleCpuIO:
42       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
43    o pkg/seaice:
44       put exchanged variable in (local) common block for MPI+Multi-Threads
45       to work (necessary with exch1, and for now with exch2 too).
46    o verification: to get more experiments tested with mpi, mth and mpi+mth,
47      change tiling of:
48       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
49       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
50      update output of exp:
51       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
52       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
53      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
54                       (note: output.txt generated on faulks using only 1 tile)
55    o eesupp & mdsio (SingleCpuIO):
56     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
57       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
58       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
59     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
60     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
61       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
62    o pkg/exch2:
63     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
64       read parameter file "data.exch2" if it exists; otherwise try default regular
65       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
66     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
67       with new code (not to be used, just as a backup solution).
68     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
69       in utils/exch2/input.
70    
71    checkpoint61n
72    o eesupp & mdsio (SingleCpuIO):
73      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
74        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
75        receive real*4 array (instead of real*8) to read/write 32.bit files.
76        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
77         and remove new mapping S/R)
78    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
79      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
80        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
81        when using exch2. Add S/R to map global io-buffer to global model array.
82      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
83    
84    checkpoint61m
85    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
86      and add 3 other S/R for other types (R4,R8,RS).
87      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
88    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
89     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
90     - reduce number of macro definitions (keep only those which are used);
91       can always call directly the corrresponding S/R if needed.
92     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
93       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
94     Fixed wrong type of arg in:
95       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
96       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
97     To fix: global_sum of var in common block is wrong (multi-threaded) in:
98       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
99     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
100    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
101      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
102    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
103    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
104      edges are closed (zero depth); might happen with "blank tiles";
105      for now, disabled if using OBCS.
106    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
107      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
108    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
109      to reduce length of 1.D array print in STDOUT.
110    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
111      + use 48 tiles (16x8): this will allow to test "blank tiles".
112    o start to test MPI + multi-threaded (change testreport to skip tests
113      where number of tiles do not match).
114    o genmake2: add option "-omp" to turn on Open-MP ;
115      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
116    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
117      and keep the original tile numbering. Note: compatible with old
118      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
119    
120    checkpoint61l
121    o Overlaps had been forgotten in calculating ijk keys : fixed
122    o fix cyrus makedepend for gcc 4.4
123    o experiment fizhi-cs-aqualev20:
124      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
125      and generate new output. Note: new output is much closer to the old
126      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
127      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
128    o pkg/fizhi:
129     - change to avoid indices going deliberately over array-bounds
130     - remove unnecessary MPI stuff
131     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
132     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
133       does not go over array-bounds and therefore returns reliable output.
134     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
135       this S/R has 4 output arguments, which are used inside "get_alarm";
136       when it is called with the same variable "ndum" in place of several
137       output arguments, this produces weird side effect inside "get_alarm"
138      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
139       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
140       address) and produces error.
141    o tools/gemake2: (March 27-29 2009)
142      with option "-mpi": link *_mpi files from "MODS" dir (this is what
143      testreport does).
144    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
145    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
146       update lab_sea.lsr & lab_sea.salt_plume results
147    o pkg/seaice:
148      Major overhaul of the LSOR solver: change discretization from original
149      finite differences to finite volume. The old routine is still in the
150      file seaice_lsr.F and can be turned on with the CPP-flag
151      SEAICE_OLD_AND_BAD_DISCRETIZATION
152      Along with this change, the discretization of the strain rates is changed.
153      The same flag turns on the old discretization in seaice_calc_strainrates.F
154      All verification experiments with seaice are affected (except for
155      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
156      results by setting the above flag.
157      Further changes involve changes in defaults:
158      - ALLOW_FLOODING is defined and turned on by default
159      - SEAICEadvSnow = .true. is now the default
160      - SEAICEadvSalt = .true. is now the default
161      - SEAICEadvAge  = .true. is now the default
162      - SEAICE_clipVelocities  = .false. is now the default
163                                         (as per J. Zhang's recommendation)
164      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
165        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
166      - seaice_growth: replace computation of UG by a simple copy from wspeed
167    
168    checkpoint61k
169    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
170      seaice_lsr: fixed a few metric terms,
171                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
172                  add more debugging diagnostics
173      seaice_evp: removed superfluous many metric terms of FV discretization
174                  of stress divergence
175                  affects lab_sea, lab_sea.hb87
176      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
177                  of stress divergence for non-evp solver
178                  (this part is not tested anywhere)
179      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
180                  they were effectively only half slip
181                  affects lab_sea.hb87
182      updated all relevant verification experiments (except lab_sea//output_adm.txt
183        which was left over, but fails at level 7 & 6)
184    
185    checkpoint61j
186    o pkg/seaice: turn a few hard wired parameters into run time parameters
187    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
188      time in seconds as promised by the usints in seaice_monitor and exf_monitor
189    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
190      that are not cubed-sphere grids
191    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
192    o pkg/ctrl:
193      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
194    o non-hydrostatic (calc_gw.F):
195      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
196      update output of exp. global_ocean.cs32x15.viscA4
197    o remove backward compatibility for thetaMin,phiMin
198      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
199    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
200      interpolated wind field not only for curvilineargrid=.true., but also
201      for a rotated grid (rotateGrid=.true.)
202    o pkg/exf: add capability to bypass interpolation for runoff
203      by setting yet another CPP-flag
204    o eesupp/src, B-grid exchange:
205      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
206    o autodiff
207      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
208      allows to switch to single-prec common blocks;
209      corresponding switch occurs in tamc.h, integer isbyte
210      TAF store directivs "byte" and "kind" seem equivalent;
211      Most tamc.h have been updated correspondingly.
212    
213    checkpoint61i
214    o autodiff:
215      fix autodiff_sore/_restore indices for obcs
216      (spotted by I. Hoteit, M. Mazloff)
217    o pkg/autodiff, pkg/ctrl:
218      Add flag to reduce all tapelev I/O to single-prec.
219      In data.ctrl set
220        doSinglePrecTapelev = .TRUE.
221    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
222      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
223    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
224      real fresh water flux (not yet)
225    o pkg/mdsio & rw:
226     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
227     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
228    o pkg/flt:
229     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
230       init_fixed & ini_varia.
231     - clean-up & simplify linear interpolation S/R:
232       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
233     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
234     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
235     - add vert. coordinate & horiz. indices to output files.
236     - change vertical position in initial condition, from index to depth [m].
237     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
238       (easier to get to a curvilinear grid) ; delX,delY no longer used.
239    o pkg/ggl90: a few modifications:
240     - fix bottom boundary condition, and interpolation of KappaE
241       near top and bottom
242     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
243     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
244     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
245    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
246      (maintain temporary backward compatibility, until next checkpoint)
247    
248    checkpoint61h
249    o pkg/diagnostics with "periodic averaging diagnostics":
250      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
251    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
252    o pkg/obcs: fix loop ranges for balancing code
253    o pkg/flt:
254     - improve criteria for finding which tile owns a float.
255     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
256    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
257      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
258      with ocean biogeo)
259    o pkg/flt:
260     - do some cleaning and fix the restart ;
261     - add output.txt in flt_example/results to get this pkg tested.
262    o genmake2: add an EXTENDED_SRC option and flag.
263       for now, cannot be turned on on command line (only through genmake_local)
264    o pkg/mdsio: read/write vector:
265     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
266     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
267       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
268     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
269      (drop to 4 digits matching for grad). But this test does not look very
270      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
271    
272    checkpoint61g
273    o pkg/flt:
274      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
275       + make OPTIONS file more standard.
276      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
277      - fix _BYTESWAPIO CPP-Flag
278      - standard reading of file-parameter "data.flt"
279      - fix argument list of S/R FLT_RESTART
280      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
281    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
282    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
283      a still unfixed compiler/optimization bug
284    
285    checkpoint61f
286    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
287      update results of global_ocean.cs32x15.icedyn test.
288    o move getcon.F from model/src to pkg/fizhi.
289    o pkg/exf: add parameter for extrapolation of temp up to the surface
290       and option to prevent negative evap (in bulk_largeyeager04 only).
291    o Prather Advection scheme: fix tracer conservation for divergent flow
292      (e.g., when using NonLin Free-Surface).
293    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
294    o gmredi (Visbeck-variable-K):
295     - add more parameters to Visbeck-variable-K.
296     - use a 5 points average for dSigmaR in Visbeck-K calculation
297       (more "homogenous": same stencil and same weights as in dSigmaH)
298     - update output of ideal_2D_oce experiment.
299    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
300      (#undef REAL4_IS_SLOW)
301     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
302       coordinate variable
303     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
304       (surface forcing fields), removes some of the functionality
305     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
306     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
307       probably not all: copy _RS surface flux fields to RL field before
308       calling DIAGNOSTICS_FILL
309     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
310       real*4 (CALL EXCH_*_RS) versions.
311     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
312       (generate new output).
313    
314    checkpoint61e
315    o gmredi (Visbeck-variable-K):
316      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
317      - change computation of Visbeck-K where Slope > Smax :        
318        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
319        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
320    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
321      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
322    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
323    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
324      does not become too large (to avoid precision problems in implicit-diffusion
325      solver); update ideal_2D_oce output.
326    o pkg ggl90:
327      - in ggl90_cal.F: compute only one set of visc/diff, used to
328        step forward TKE/T/S/momentum
329      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
330        have Prandlt =1)
331    o gmredi (fm07):
332      - add lower limit on Transition layer thickness + lower limit on 1/lambda
333      - allow to set few more params from data.gmredi
334    o pkg ggl90:
335          - add missing sqrt(2) factor in computation of mixing length
336            scale in ggl90_calc.F
337            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
338    
339    checkpoint61d
340    o adjoint modifs
341      - adapt to new field rhoInSitu
342      - allow to revert from StoreDynVars2D, StoreDynVars3D
343        to individual fields
344        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
345    o store 3-D (in-situ) density in commom block (DYNVARS.h)
346     - save 1 rho computation.
347     - no longer modify T & S inland when using down_slope pkg.
348    o gad_som : allow to switch to SOM advection for T & S without corresponding
349      pickup files (using new S/R: MDS_CHECK4FILE).
350    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
351      (for useSingleCpuIO to work in multi-threaded)
352    o pkg/shelfice:
353     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
354       with SHELFICEtopoFile in data.shelfice
355     - move code for reading ice shelf topography and modifying hFacC into separate
356       subroutines of the shelfice package
357     - separate initialisation of "fixed" and "variable" variables
358     - kTopC is not (yet) replaced by kSurfC, although this is possible
359    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
360    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
361      and rename:
362      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
363      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
364    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
365    
366    checkpoint61c
367    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
368      to add mass source/sink of fluid in the interior (3-D generalisation
369      of oceanic real-fresh water flux).
370    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
371    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
372    o new pkg: down_slope
373      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
374      - presently, modify T & S inland (dwnslp_calc_rho.F).
375        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
376      - implementation for ocean in P-coords not tested.
377      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
378    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
379      (to facilitate conversion of oceanic pkg to p-coordinate).
380    o change FIND_RHO to FIND_RHO_2D :
381      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
382    o new pkg: cheapaml
383    
384    checkpoint61b
385    o exch2:
386      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
387      - no longer depend on the order sequence (N,S,E,W).
388      - 3rd exchange no longer needed (tested with 24 tiles).
389      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
390      - exch_UV_A-grid readily available (but not yet tested).
391      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
392      (both are no longer needed) in exch_uv: no effect in forward run; but
393       get truncation error differences with adjoint exch.
394    o exch2:
395     - change index-bounds storage (moved from target to local tile,
396       more intuitive this way) ; rename/remove some variables.
397     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
398    
399    checkpoint61a
400    o exch2/matlab-topology-generator:
401      fix bug in index bounds for N-S internal exchange (hard to tell if this
402      had any effect on the solution).
403    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
404      is exceeded
405    o testreport: modify syntax of awk, so that it works also with
406      awk, and not only with nawk and gawk
407    
408    checkpoint61
409    o autodiff
410      Change default for TAF usage by removing argument '-nonew_arg'
411      This changes TAF subroutine argument list (ordering of active var.)
412      Omission of this flag leads to incompatibility w.r.t. TAMC
413      To restore TAMC-compatibility, need following modifs:
414      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
415      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
416      Tested TAF version is 1.9.22
417      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
418    
419    checkpoint60
420    --->>> This is the last checkpoint for which generating the adjoint
421    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
422    --->>> by default.
423    --->>> Future checkpoints will ommit this flag by default.
424    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
425    o pkg/grdchk: Add gradient check to etan0 perturbations.
426    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
427    o pkg/autodiff: more flexibility in zeroadj.
428      model/src: modifying do_oceanic_phys.F accordingly.
429    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
430    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
431      special setup of gmredi for which the adjoint is stable
432      enough for parameter optimization.
433    o bridging the gap between eddy stress and GM.
434      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
435          along with a change in CPP option (now ALLOW_EDDYPSI).
436      -> when using GM w/ GM_AdvForm:
437          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
438          is applied either in the tracer Eq. or in momentum Eq.
439          depending on data.gmredi (intro. GM_InMomAsStress).
440      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
441      The key modifications are in model/src/taueddy_external_forcing.F
442      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
443    
444    checkpoint59r
445    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
446      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
447      fix option to read coriolis(@ cell-corner) from files with CS-grid.
448    o pkg/mnc: add some attributes to standard 1D-coordinate variables
449    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
450      mass points, when using mnc for output
451      - add runtime parameter (missing_value, missing_value_int) to override
452        default (which is the value of getcon('UNDEF'))
453    o pkg/mnc: prepare mnc for the actual use of missing values with the
454      diagnostics package: small fix in mnc_cw_readwrite.template and more
455      initialisation of never used fields
456      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
457      versions
458    o pkg/thsice/thsice_ini_vars.F added default initial values so that
459      thermodynamics sea ice solver does not blow up when some initial fields
460      are missing.
461    o move from external_forcing_surf.F to ini_forcing.F
462      the p-coord. hack consisting in using pLoad to set phi0surf ;
463      update output of tutorial_global_oce_in_p (affected @ truncation level).
464    o Freshen up a bit hs94.1x64x5, notably:
465      remove rotationPeriod and tRef=5*0. (adjoint only), and add
466      exactConserv=.TRUE.
467    o pkg/generic_advdiff:
468      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
469      applies to files where Temperature & Salinity 2nd Order moments are used.
470    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
471      this uses a dynamically allocated internal state data structure
472      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
473      and requires a fortran 90 compiler
474    
475    checkpoint59q
476    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
477       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
478    o Refresh tutorial_global_oce_biogeo, notably:
479      - change bathymetry (put back seamounts in ACC, use hFacs)
480      - change EOS (POLY3 --> JMD95Z)
481      - use Bryan-Lewis vertical diffusivity
482      - use multidimensional advection
483      - remove old virtual virtual in dic pkg, now done through ptracer pkg
484      - change a couple of parameters in dic pkg
485    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
486    o pkg/obcs: change default to OBCSfixTopo = .true.,
487      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
488      - replace "debugMode" with "debugLevel .GE. debLevB"
489    o implementation of TAF directives for gchem,cfc,dic
490    o remove "exp5" (replaced by tutorial_deep_convection).
491    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
492      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
493      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
494      --> changes results in exp4, seaice_obcs
495    o tutorial_deep_convection :
496      update the set-up and increase resolution and domain size ; start
497      from pseudo initial conditions = output at t=120mn in order to see
498      something happening when running testreport.
499    o pkg/seaice: add os7mp as an advection scheme
500                  add check for advection schemes
501                  add a flag for restoring T and S underneath sea ice
502    o pkg/my82: add netcdf-support and diagnostics
503    o thsice pkg:
504      - Now hsMax limits snow height by turning it into ice following
505        flooding scheme (and now conserving energy)
506      - Slight rewriting of the formula in thsice_calc_thick.F
507      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
508      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
509    
510    checkpoint59p
511    o gchem / dic / cfc :
512      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
513      - add new parameter files: "data.dic" & "data.cfc" ;
514      - various re-arrangement in initialisation & header file ;
515      - fix tutorial_global_oce_biogeo for multi-threaded test.
516    o pkg/dic: test for "pickup_dic" file when restarting ;
517      if no pickup-file, can restart with a re-initialised pH (same as it did
518      before) providing pickupStrictlyMatch is set to False.
519    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
520      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
521    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
522      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
523    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
524     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
525       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
526    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
527       scheme to use for vorticty-term ;
528     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
529       (with default selectVortScheme, return to original discretisation)
530     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
531    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
532    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
533      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
534      also fix diagnostics VISCAHW & VISCA4W.
535    
536    checkpoint59o
537    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
538    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
539      move a few statemens out the main loop into separate loops
540    o pkg/shelfice:
541      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
542        (kg/m^2/s), does not break tests, because in verification/isomip,
543        rhoConstFresh=rhoConst (by accident)
544      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
545      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
546        new file model/src/seawater.F, so that they are available for all pkgs.
547      - convert potential temperature into in-situ temperature. This changes the
548        isomip tests => update tests
549    o add a flag writePickupAtEnd (default=true) to be able to suppress
550      writing a pickup at the last timestep
551    o tools/mpack-1.6 :
552      - disable automake (not working) and autoconf (not needed).
553      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
554        also cleaner with much less compilation warnings.
555    o pkg/profiles:
556      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
557      (for "less than 32 characters name" compiler requirement)
558    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
559      conditions that have a different sampling frequency than S/T/U/V obcs
560    o pkg/diagnostics (stats-diags):
561      - fix global Min/Max in case 1 processor get only empty tiles
562    o genmake2: replace (4 times)
563         make genmake_tc_1.o >> genmake_warnings 2>&1
564      with
565         COMM="$CC $CFLAGS -c genmake_tc_1.c"
566         echo $COMM >> genmake_warnings
567         $COMM >> genmake_warnings 2>&1
568      to make genmake2 always see the value of CC as specified in the optfile.
569    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
570      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
571      - modify verification advect_cs test to test SOM-advection on CS-grid.
572    o pkg/ctrl:
573      - Rewrite of ctrl_map_ini_ecco.F,
574        introducing a generic routine (ctrl_map_ini_gen.F).
575      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
576    
577    checkpoint59n
578    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
579      number in dedicate array "hdiag":
580      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
581        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
582      - many small changes (integer format) for large number of diagnostics
583      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
584        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
585    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
586      usingSphericalGrid, this allows to define the rotated grid coordinates
587      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
588      geographical coordinates according to the inverse of the rotation defined
589      by the Euler angles, so that Coriolis parameter and online-interpolation by
590      exf works with the geographical coordinates on XC/YC/XG/YG.
591      Naturally, this feature does not work with all packages, so some
592      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
593      profiles), because there the coordinates are assumed to be regular
594      spherical grid coordinates.
595    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
596      - introduce isopycnal diffusion coefficient control.
597    o tools/adjoint_options:
598      - additional control vector components.
599    o pkg/mnc: have mnc create marginally meaning full coordinate variables
600      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
601    o pkg/mypackage:
602      - add example of read/write pickup for state-var ;
603      - add entry points to the main code for state-vars diags & write-pickup.
604    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
605      transitions for useExfYearlyFields
606      - add new subroutine that determines the file to read from for
607        use*YearlyFields = .TRUE. and .FALSE.
608      - add a verification experiment to global_with_exf that tests
609        useExfYearlyFields with USE_EXF_INTERPOLATION defined
610    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
611      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
612      subroutines (which could be generated from a template, because they are
613      almost identical), for now they are included in obcs_prescribe_read.F for
614      simplicity
615    o pkg/exf:
616      - add a little more diagnostic to exf_interp_read (in analogy to
617        mds_read_field, can be turned off with debugLevel < debugLevA=1)
618      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
619        ugly but fast by unrolling short inner loops, inserting a unroll=8
620        directive in routine lagran, and splitting a loop and making do while the
621        outermost loop (the latter requires the intoduction of index arrays)
622    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
623    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
624      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
625    o verification/seaice_obcs: updated for restart test and latest options
626    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
627      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
628      for now this is only available for the C-grid code and also within
629      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
630    
631    checkpoint59m
632    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
633      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
634    o gad_som : fix flux output (& diagnostics) to have same units as other  
635      advection scheme fluxes (was previously multiplied by deltaT).  
636    o added verification/seaice_obcs both to test seaice open boundaries
637      and to provide an example matlab scrpt for generating them
638    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
639    o pkg/salt_plume: clean up salt_plume_frac.F to
640      remove redundancy in PlumeMethod 1 and 4
641    o pkg/kpp: added saltplume diagnostics
642    o pkg/obcs and pkg/seaice:
643      - do not set uice and vice to zero when OB*icefile are unspecified
644      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
645      - moved seaice tracer obcs after call to seaice_growth
646    o pkg/salt_plume: added various options for salt plume depth
647      criterion and for vertical distribution of the salt
648    
649    checkpoint59l
650    o pkg/ptracers: new version of ptracers pickup:
651      read meta file and write only fields which are needed to restart.
652      ( same logic as main pickup file ; also using pickupStrictlyMatch )
653    o pkg/seaice:
654      - add timescale for melting due to warm mixed layer as a means of
655        setting SEAICE_availHeatFrac more conveniently
656      - add a CPP-flag/runtime parameter check for flooding algorithm
657      - reformulated availHeat in seaice_growth.F to be independent of AREA
658    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
659      unit changes
660    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
661    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
662      SX vector computer.
663    o pkg/seaice:
664      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
665        seaice forcing fields can now be read only through pkg/exf
666      - removed some unused halos
667    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
668    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
669      or U/VICE from U/VWIND before computing U/VSTRESS
670    
671    checkpoint59k
672    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
673      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
674    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
675      all experiments pass when compile with un-initialised var. checking option.
676    o added pkg/salt_plume
677    o script to test restart (for now, in MITgcm_contrib/jmc_script)
678    o pkg/seaice: new read/write pickup version.
679      read meta file and write only fields which are needed to restart.
680      ( same logic as main pickup file ; also using pickupStrictlyMatch )
681    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
682    o lab_sea.hb87: modify the domain & update output.hb87.txt :
683      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
684      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
685      process. Fixed here by closing the domain at the Northern boundary.
686    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
687    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
688      a set of consecutive levels in/from a 3-D array.
689    o pkg/ptracers:
690      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
691      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
692    
693    checkpoint59j
694    o in pkgs: dic, obcs, offline, rbcs:
695      standard way to compute coeff. for time interpolation between 2 time reccords
696      which retains full precision (& make results less dependent on compiler).
697      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
698    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
699      packages instead of reading ice cover and wind speed separately
700    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
701     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
702      to allow to compile customized code before the update)
703    o cleaning-up:
704      - fix CPP instruction syntax in pkg/obcs
705      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
706        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
707      - fix some threads issue in IO parts.
708    o pkg/dic:
709      - add tons of "_d 0" (--> much better testreports !)
710       and then update outputs of tutorial_global_oce_biogeo
711    o pkg/mom_fluxform:
712      add a special version of momentum advection intended to conserve momentum
713      next to a bathymetry step or a coastline edge. (default = off = #undef)
714    o new read/write pickup version:
715      - for now, only implemented for main (mdsio) pickup file.
716      - write out only what is needed to restart; merge pickup_nh , pickup_ph
717        and main pickup together.
718      - read meta file; read only what is needed to restart; stop if a field
719        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
720        if it make sense (even if the restart is not perfect).
721      - if no meta file, assume that pickup to read corresponds exactly to
722        a pickup that would currently be written.
723      - read pickup written in the old format (until checkpoint59i) if it
724        recognizes an old meta file (no field-list).
725      - add a meta file in exp. which starts from a pickup: 2 cases:
726        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
727         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
728        b) a meta file describing the content of the associated pickup file
729         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
730    o pkg/mdsio & pkg/rw:
731      - new routine to read a meta file ; new set of routine to read
732        Multiple-fields file (with meta file).
733    o added open boundary conditions capability for seaice
734        HSNOW, HSALT, UICE, and VICE
735    
736    checkpoint59i
737    o adjoint:
738      * fix multiDimAdvection adjoint
739        (partial recomputation problem by TAF for fVerT(:,:,kDown)
740        and comlev1 size definition (maxpass vs. max. number of tracers)
741      * verification/global_ocean.90x45x15 adjoint now tests
742        NLFS and multiDimAdvection using DST3 (=30)
743      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
744    o pkg/kpp: add "_d 0" to real constant (if missing);
745      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
746      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
747    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
748      for internal parameters related to restart process (formerly from PARAMS.h)
749      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
750    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
751      as argument. (only atm2d & obcs write_pickup have not yet been updated)
752    o pkg/monitor:
753      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
754      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
755      - account for deep Atmosphere factor and density factor (anelastic)
756    o added open boundary conditions capability for seaice HEFF and AREA
757    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
758      thermodynamics
759      - requires a little reorganization, which affects the testreport results
760        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
761        so that now the conservative form is tested
762      - add a few comments
763    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
764    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
765    o add new diagnostics to seaice: advective, diffusive fluxes (only for
766      multidim-advection, for scheme 2 they are not filled) and transports,
767      thermodynamic growth rates
768    o change units of EmPmR (inside the code, + within coupling interface)
769      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
770      Affects results @ truncation level (cg2d match) and update output of
771       experiments: lab_sea(6), global_ocean.90x40x15(10),
772      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
773      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
774      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
775      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
776    
777    checkpoint59h
778    o pkg/exf:
779      - improve vectorization by moving if-statement out of loops in
780        exf_mapfields, exf_radiation
781      - exf_bulkformulae.F: introduce 2D fields and vectorize code
782    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
783    o testreport:
784      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
785        monitor & update offline_exf_seaice exp. output.
786      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
787    o pkg/seaice:
788      - bug fix in the evp solver: boundary conditions were affected be
789        masking of zMax/zMin (changes results)
790      - minor bug fix in boundary conditions in seaice_calc_strainrates
791        (changes results for no_slip)
792      - seaice_lsr.F: make interpolation of eta dependent on boundaries
793      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
794      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
795        stress formulation and no-slip boundary conditions
796    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
797      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
798    o pkg/seaice: a first HSALT time stepping equation has been checked in
799    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
800      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
801      without requiring DO-IF statements
802    o pkg/thsice:
803      use continuous power-law function for partition of energy between lateral
804      melting/freezing and thinning/thickening ; old code using step function
805      still available with #undef THSICE_FRACEN_POWERLAW
806      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
807    o testreport: change AD testing : check against results/output_adm.txt
808      using same scripts as for forward test.
809    
810    checkpoint59g
811    o adjoint testing: in preparation for changing testreport:
812      - output format: cost and grad written on separated lines
813      - ad output results in directory "results" (instead of "results_ad")
814    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
815    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
816    o pkg/ecco: allow user defined cost function contributions
817    o testreport:
818      Allow to choose (per experiment) the list of tested output variables
819       and the main variable (used to issue a pass/FAIL ) ;
820      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
821      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
822      Also modify printing of summary:
823       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
824       b) echo the list of tested variables in the individual summary.txt of
825          each experiment.
826    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
827      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
828      (but still depend on the tile decompostion of the domain).
829    o pkg/seaice: change a discretization detail to make the B-grid code
830      "more symmetric". This change is likely to remove all "ridges/leads" that
831      where quasi-aligned with the grid in B-grid solutions. It may also be
832      the solution to the stress coupling issues with the B-grid.
833    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
834      remove .cvsignore from input dir. (since testreport no longer run here).
835    o pkg/thsice:
836     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
837     - fix reshaping of sea-ice just after advection:
838       melt all the ice only if ice-volume is too small.
839     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
840       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
841     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
842    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
843      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
844    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
845      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
846      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
847      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
848      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
849      -> update output.txt
850    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
851     this affects truncation error: -> update output.txt of exp:
852      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
853      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
854    
855    checkpoint59f
856    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
857    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
858      a bounded range (in forward mode)
859    o pkg/ecco, ctrl, autodiff and mom_common:
860     internal parameter controls, completements of implementations
861    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
862    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
863      (not seem any difference in testing results).
864    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
865       at face corners.
866    o pkg/generic_advdiff:
867     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
868      loop range indices for computing vertical advection tendency
869      and do the calculation in the interior only (no overlap) ;
870      for now, only implemented for SOM advection (to save CPU time).
871     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
872    o exch2 adjoint
873      First set of changes:
874      - add exch2 hand-written adjoint templates
875      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
876        This will require cleanup in pkg/autodiff/*.F
877        (changed routines currently kept separate in verif. code/)
878      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
879        that used to hide exch2 or cubed-sphere specific code
880        (commented via 'cph-exch2')
881    o pkg/seaice
882      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
883    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
884       output of global_ocean.cs32x15.thsice .
885    
886    checkpoint59e
887    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
888      for B-grid vector (not yet tested) and C-grid vector (<- only used
889      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
890    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
891      (#ifdef ALLOW_SALT_PLUME)
892    o gather_2d/scatter_2d: removed halo regions
893    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
894      scheme and the corresponding test case (under front_relax dir). For now,
895      only available with Skew-flux form and not yet tested in realistic set-up.
896      adjoint: store directives updated, but gradient checks deteriorated,
897      so maybe GM/Redi adjoint is now broken.
898    o seaice adjoint
899      * add AREA, HEFF, HSNOW as control variable
900        (should not change lab_sea results)
901      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
902    o pkg/seaice:
903      * added computation of saltFlux in seaice_growth;
904        For time being, sea ice salinity is assumed constant
905        contribution of snow flooding to freshening of sea ice is neglected.
906        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
907        defaults to 0.0 in order to maintain backward compatibility.
908        Typical values for SEAICE_salinity are 4 to 10 g/kg.
909      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
910      * added SEAICE_availHeatFrac, which specifies fraction of surface level
911        heat content used to melt or grow ice
912      * commented out cap of HICE: it helps keep ice thinner
913      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
914      * applied OBCS T/S mask to HEFFM sea ice mask
915    
916    checkpoint59d
917    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
918     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
919     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
920    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
921     and change default value of parameter "GM_Small_Number";
922     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
923       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
924       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
925    o pkg/ecco: cost function when applying pkg/smooth to controls
926    o pkg/ctrl: add forcingPrecond run time parameter
927    o pkg/seaice:
928     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
929     - fix bug in metric terms of u-equation in LSR solver (implicit part),
930       changes verification/lab_sea
931     - rearrange implicit part of u-equation in LSR solver to make it easier to
932       read, understand, and debug. This causes changes at the truncation level.
933     - fix (serious) bug in the boundary conditions (sign error in the implicit
934       part) of the LSR solver. Changes all LSR results.
935     - fixed problem with HSNOW initialization to avoid thick snow when AREA
936       is initilized with small values - does not change lab_sea results.
937     - added HsnowFile initialization capability
938    o pkg/smooth: addition to model/src and pkg/ctrl so allow
939     initialization of pkg/smooth and application to control vector
940    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
941    o dependencies: pkg/profiles requires pkg/cal
942    o pkg/profiles:
943     - added option ALLOW_PROFILES_GENERICGRID
944         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
945         that interpolation information (grid points and coefficients) is provided
946         within the netcdf input files.
947         -> sample matlab scripts can be found in MITgcm_contrib/gael
948         that allow you to prepare netcdf input files.
949     - also modified: cleaner include statements, cleaner error print statements,
950       cleaner stops when error, and more tests of the netcdf input files consistency.
951  o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.  o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
952  o pkg/seaice:  o pkg/seaice:
