4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o eesupp (global_max & global_sum):
8     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
9     - remove starting & endding barrier (no longer needed)
10    o pkg/mdsio, writelocal:
11       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
12       (remove the STOP): uses shared buffer IO to store data from all threads
13       and then let master-thread write nThreads tiles.
14    o pkg/mdsio (read/write field):
15     - tiled IO done in 1 piece (all levels at a time);
16     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
17     - multi-threaded: allow to read/write local (non-shared) array
18       (was already working with singleCpuIO ; now works also without);
19       => no longer needs barrier call after reading a file (added inside
20       mds_read/write field).
21     - move barrier calls outside gather/scatter_2d to mds_read/write_field
22    o pkg/obcs/exf
23      - exf_getffieldrec.F: add a few ". _d 0" and
24                            add code to catch the case fldperiod = 0.  
25      - obcs_precribe_read.F: change if statements so that they match
26                              the variable type (_RL)
27      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
28        exf_iprec) as part of namelist EXF_NML_01
29    o pkg/mdsio:
30      - read/write tiled (local) files: read/write 1-level tile chunk at a time
31        (instead of segment of length sNx); expected to speed up tiled IO.
32    o pkg/exch2:
33      - take buffer copy from/to array out of S/R exch2_send/recv into new
34        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
35        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
36      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
37      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
38        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
39        including Topology header file (and common blocks).
40      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
41        remove 2nd exch call in exch2_s3d_rx (no longer needed).
42      - document S/R arg. list (+ update some comments)
43    o pkg/seaice:
44      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
45        temperature and humidity over sea ice based on climatological values.
46      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
47        of LSR (this change is expected to change the results slightly because now
48        it uses slightly difference moduli from the second last LSR solution, but
49        that is more consistent with the stress computations; this part of the code
50        is not tested in the verification experiments)
51      - fix diagnostics for flux of ice in case of B-grid
52      - turn strain rates eij and press into global fields within global
53        common block in SEAICE.h for more straighforward diagnostics
54      - fix diagnostics for principal stress components, press, zeta, eta
55        to give something meaning full
56    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
57      new output (all 4 tests) using default rotationPeriod.
58    o pkg KPP:
59      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
60      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
61        and normal grid from 1 to Nr)
62    o Fix computations of L4rdt in mom_calc_visc.F
63    o eesupp:
64      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
65      should be called before a "stop" if we know that all process are going
66      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
67    
68    checkpoint61o
69    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
70    o model/src/ini_curvilinear_grid.F:
71       compute angleSin/CosC when they are not read from a file
72    o pkg/seaice:
73       add pseudo time stepping for LSOR
74    o pkg/exch2:
75       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
76    o pkg/seaice:
77       Adding separate sea ice albedo, drag coefficients, and HO in Southern
78       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
79    o SingleCpuIO:
80       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
81    o pkg/seaice:
82       put exchanged variable in (local) common block for MPI+Multi-Threads
83       to work (necessary with exch1, and for now with exch2 too).
84    o verification: to get more experiments tested with mpi, mth and mpi+mth,
85      change tiling of:
86       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
87       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
88      update output of exp:
89       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
90       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
91      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
92                       (note: output.txt generated on faulks using only 1 tile)
93    o eesupp & mdsio (SingleCpuIO):
94     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
95       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
96       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
97     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
98     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
99       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
100    o pkg/exch2:
101     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
102       read parameter file "data.exch2" if it exists; otherwise try default regular
103       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
104     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
105       with new code (not to be used, just as a backup solution).
106     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
107       in utils/exch2/input.
108    
109    checkpoint61n
110    o eesupp & mdsio (SingleCpuIO):
111      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
112        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
113        receive real*4 array (instead of real*8) to read/write 32.bit files.
114        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
115         and remove new mapping S/R)
116    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
117      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
118        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
119        when using exch2. Add S/R to map global io-buffer to global model array.
120      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
121    
122    checkpoint61m
123    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
124      and add 3 other S/R for other types (R4,R8,RS).
125      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
126    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
127     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
128     - reduce number of macro definitions (keep only those which are used);
129       can always call directly the corrresponding S/R if needed.
130     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
131       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
132     Fixed wrong type of arg in:
133       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
134       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
135     To fix: global_sum of var in common block is wrong (multi-threaded) in:
136       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
137     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
138    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
139      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
140    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
141    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
142      edges are closed (zero depth); might happen with "blank tiles";
143      for now, disabled if using OBCS.
144    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
145      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
146    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
147      to reduce length of 1.D array print in STDOUT.
148    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
149      + use 48 tiles (16x8): this will allow to test "blank tiles".
150    o start to test MPI + multi-threaded (change testreport to skip tests
151      where number of tiles do not match).
152    o genmake2: add option "-omp" to turn on Open-MP ;
153      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
154    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
155      and keep the original tile numbering. Note: compatible with old
156      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
157    
158    checkpoint61l
159    o Overlaps had been forgotten in calculating ijk keys : fixed
160    o fix cyrus makedepend for gcc 4.4
161    o experiment fizhi-cs-aqualev20:
162      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
163      and generate new output. Note: new output is much closer to the old
164      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
165      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
166    o pkg/fizhi:
167     - change to avoid indices going deliberately over array-bounds
168     - remove unnecessary MPI stuff
169     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
170     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
171       does not go over array-bounds and therefore returns reliable output.
172     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
173       this S/R has 4 output arguments, which are used inside "get_alarm";
174       when it is called with the same variable "ndum" in place of several
175       output arguments, this produces weird side effect inside "get_alarm"
176      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
177       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
178       address) and produces error.
179    o tools/gemake2: (March 27-29 2009)
180      with option "-mpi": link *_mpi files from "MODS" dir (this is what
181      testreport does).
182    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
183    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
184       update lab_sea.lsr & lab_sea.salt_plume results
185    o pkg/seaice:
186      Major overhaul of the LSOR solver: change discretization from original
187      finite differences to finite volume. The old routine is still in the
188      file seaice_lsr.F and can be turned on with the CPP-flag
189      SEAICE_OLD_AND_BAD_DISCRETIZATION
190      Along with this change, the discretization of the strain rates is changed.
191      The same flag turns on the old discretization in seaice_calc_strainrates.F
192      All verification experiments with seaice are affected (except for
193      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
194      results by setting the above flag.
195      Further changes involve changes in defaults:
196      - ALLOW_FLOODING is defined and turned on by default
197      - SEAICEadvSnow = .true. is now the default
198      - SEAICEadvSalt = .true. is now the default
199      - SEAICEadvAge  = .true. is now the default
200      - SEAICE_clipVelocities  = .false. is now the default
201                                         (as per J. Zhang's recommendation)
202      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
203        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
204      - seaice_growth: replace computation of UG by a simple copy from wspeed
205    
206    checkpoint61k
207    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
208      seaice_lsr: fixed a few metric terms,
209                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
210                  add more debugging diagnostics
211      seaice_evp: removed superfluous many metric terms of FV discretization
212                  of stress divergence
213                  affects lab_sea, lab_sea.hb87
214      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
215                  of stress divergence for non-evp solver
216                  (this part is not tested anywhere)
217      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
218                  they were effectively only half slip
219                  affects lab_sea.hb87
220      updated all relevant verification experiments (except lab_sea//output_adm.txt
221        which was left over, but fails at level 7 & 6)
222    
223    checkpoint61j
224    o pkg/seaice: turn a few hard wired parameters into run time parameters
225    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
226      time in seconds as promised by the usints in seaice_monitor and exf_monitor
227    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
228      that are not cubed-sphere grids
229    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
230    o pkg/ctrl:
231      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
232    o non-hydrostatic (calc_gw.F):
233      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
234      update output of exp. global_ocean.cs32x15.viscA4
235    o remove backward compatibility for thetaMin,phiMin
236      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
237    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
238      interpolated wind field not only for curvilineargrid=.true., but also
239      for a rotated grid (rotateGrid=.true.)
240    o pkg/exf: add capability to bypass interpolation for runoff
241      by setting yet another CPP-flag
242    o eesupp/src, B-grid exchange:
243      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
244    o autodiff
245      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
246      allows to switch to single-prec common blocks;
247      corresponding switch occurs in tamc.h, integer isbyte
248      TAF store directivs "byte" and "kind" seem equivalent;
249      Most tamc.h have been updated correspondingly.
250    
251    checkpoint61i
252    o autodiff:
253      fix autodiff_sore/_restore indices for obcs
254      (spotted by I. Hoteit, M. Mazloff)
255    o pkg/autodiff, pkg/ctrl:
256      Add flag to reduce all tapelev I/O to single-prec.
257      In data.ctrl set
258        doSinglePrecTapelev = .TRUE.
259    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
260      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
261    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
262      real fresh water flux (not yet)
263    o pkg/mdsio & rw:
264     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
265     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
266    o pkg/flt:
267     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
268       init_fixed & ini_varia.
269     - clean-up & simplify linear interpolation S/R:
270       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
271     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
272     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
273     - add vert. coordinate & horiz. indices to output files.
274     - change vertical position in initial condition, from index to depth [m].
275     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
276       (easier to get to a curvilinear grid) ; delX,delY no longer used.
277    o pkg/ggl90: a few modifications:
278     - fix bottom boundary condition, and interpolation of KappaE
279       near top and bottom
280     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
281     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
282     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
283    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
284      (maintain temporary backward compatibility, until next checkpoint)
285    
286    checkpoint61h
287    o pkg/diagnostics with "periodic averaging diagnostics":
288      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
289    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
290    o pkg/obcs: fix loop ranges for balancing code
291    o pkg/flt:
292     - improve criteria for finding which tile owns a float.
293     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
294    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
295      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
296      with ocean biogeo)
297    o pkg/flt:
298     - do some cleaning and fix the restart ;
299     - add output.txt in flt_example/results to get this pkg tested.
300    o genmake2: add an EXTENDED_SRC option and flag.
301       for now, cannot be turned on on command line (only through genmake_local)
302    o pkg/mdsio: read/write vector:
303     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
304     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
305       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
306     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
307      (drop to 4 digits matching for grad). But this test does not look very
308      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
309    
310    checkpoint61g
311    o pkg/flt:
312      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
313       + make OPTIONS file more standard.
314      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
315      - fix _BYTESWAPIO CPP-Flag
316      - standard reading of file-parameter "data.flt"
317      - fix argument list of S/R FLT_RESTART
318      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
319    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
320    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
321      a still unfixed compiler/optimization bug
322    
323    checkpoint61f
324    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
325      update results of global_ocean.cs32x15.icedyn test.
326    o move getcon.F from model/src to pkg/fizhi.
327    o pkg/exf: add parameter for extrapolation of temp up to the surface
328       and option to prevent negative evap (in bulk_largeyeager04 only).
329    o Prather Advection scheme: fix tracer conservation for divergent flow
330      (e.g., when using NonLin Free-Surface).
331    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
332    o gmredi (Visbeck-variable-K):
333     - add more parameters to Visbeck-variable-K.
334     - use a 5 points average for dSigmaR in Visbeck-K calculation
335       (more "homogenous": same stencil and same weights as in dSigmaH)
336     - update output of ideal_2D_oce experiment.
337    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
338      (#undef REAL4_IS_SLOW)
339     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
340       coordinate variable
341     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
342       (surface forcing fields), removes some of the functionality
343     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
344     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
345       probably not all: copy _RS surface flux fields to RL field before
346       calling DIAGNOSTICS_FILL
347     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
348       real*4 (CALL EXCH_*_RS) versions.
349     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
350       (generate new output).
351    
352    checkpoint61e
353    o gmredi (Visbeck-variable-K):
354      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
355      - change computation of Visbeck-K where Slope > Smax :        
356        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
357        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
358    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
359      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
360    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
361    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
362      does not become too large (to avoid precision problems in implicit-diffusion
363      solver); update ideal_2D_oce output.
364    o pkg ggl90:
365      - in ggl90_cal.F: compute only one set of visc/diff, used to
366        step forward TKE/T/S/momentum
367      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
368        have Prandlt =1)
369    o gmredi (fm07):
370      - add lower limit on Transition layer thickness + lower limit on 1/lambda
371      - allow to set few more params from data.gmredi
372    o pkg ggl90:
373          - add missing sqrt(2) factor in computation of mixing length
374            scale in ggl90_calc.F
375            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
376    
377    checkpoint61d
378    o adjoint modifs
379      - adapt to new field rhoInSitu
380      - allow to revert from StoreDynVars2D, StoreDynVars3D
381        to individual fields
382        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
383    o store 3-D (in-situ) density in commom block (DYNVARS.h)
384     - save 1 rho computation.
385     - no longer modify T & S inland when using down_slope pkg.
386    o gad_som : allow to switch to SOM advection for T & S without corresponding
387      pickup files (using new S/R: MDS_CHECK4FILE).
388    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
389      (for useSingleCpuIO to work in multi-threaded)
390    o pkg/shelfice:
391     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
392       with SHELFICEtopoFile in data.shelfice
393     - move code for reading ice shelf topography and modifying hFacC into separate
394       subroutines of the shelfice package
395     - separate initialisation of "fixed" and "variable" variables
396     - kTopC is not (yet) replaced by kSurfC, although this is possible
397    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
398    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
399      and rename:
400      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
401      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
402    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
403    
404    checkpoint61c
405    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
406      to add mass source/sink of fluid in the interior (3-D generalisation
407      of oceanic real-fresh water flux).
408    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
409    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
410    o new pkg: down_slope
411      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
412      - presently, modify T & S inland (dwnslp_calc_rho.F).
413        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
414      - implementation for ocean in P-coords not tested.
415      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
416    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
417      (to facilitate conversion of oceanic pkg to p-coordinate).
418    o change FIND_RHO to FIND_RHO_2D :
419      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
420    o new pkg: cheapaml
421    
422    checkpoint61b
423    o exch2:
424      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
425      - no longer depend on the order sequence (N,S,E,W).
426      - 3rd exchange no longer needed (tested with 24 tiles).
427      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
428      - exch_UV_A-grid readily available (but not yet tested).
429      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
430      (both are no longer needed) in exch_uv: no effect in forward run; but
431       get truncation error differences with adjoint exch.
432    o exch2:
433     - change index-bounds storage (moved from target to local tile,
434       more intuitive this way) ; rename/remove some variables.
435     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
436    
437    checkpoint61a
438    o exch2/matlab-topology-generator:
439      fix bug in index bounds for N-S internal exchange (hard to tell if this
440      had any effect on the solution).
441    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
442      is exceeded
443    o testreport: modify syntax of awk, so that it works also with
444      awk, and not only with nawk and gawk
445    
446    checkpoint61
447    o autodiff
448      Change default for TAF usage by removing argument '-nonew_arg'
449      This changes TAF subroutine argument list (ordering of active var.)
450      Omission of this flag leads to incompatibility w.r.t. TAMC
451      To restore TAMC-compatibility, need following modifs:
452      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
453      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
454      Tested TAF version is 1.9.22
455      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
456    
457    checkpoint60
458    --->>> This is the last checkpoint for which generating the adjoint
459    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
460    --->>> by default.
461    --->>> Future checkpoints will ommit this flag by default.
462    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
463    o pkg/grdchk: Add gradient check to etan0 perturbations.
464    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
465    o pkg/autodiff: more flexibility in zeroadj.
466      model/src: modifying do_oceanic_phys.F accordingly.
467    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
468    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
469      special setup of gmredi for which the adjoint is stable
470      enough for parameter optimization.
471    o bridging the gap between eddy stress and GM.
472      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
473          along with a change in CPP option (now ALLOW_EDDYPSI).
474      -> when using GM w/ GM_AdvForm:
475          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
476          is applied either in the tracer Eq. or in momentum Eq.
477          depending on data.gmredi (intro. GM_InMomAsStress).
478      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
479      The key modifications are in model/src/taueddy_external_forcing.F
480      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
481    
482    checkpoint59r
483    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
484      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
485      fix option to read coriolis(@ cell-corner) from files with CS-grid.
486    o pkg/mnc: add some attributes to standard 1D-coordinate variables
487    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
488      mass points, when using mnc for output
489      - add runtime parameter (missing_value, missing_value_int) to override
490        default (which is the value of getcon('UNDEF'))
491    o pkg/mnc: prepare mnc for the actual use of missing values with the
492      diagnostics package: small fix in mnc_cw_readwrite.template and more
493      initialisation of never used fields
494      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
495      versions
496    o pkg/thsice/thsice_ini_vars.F added default initial values so that
497      thermodynamics sea ice solver does not blow up when some initial fields
498      are missing.
499    o move from external_forcing_surf.F to ini_forcing.F
500      the p-coord. hack consisting in using pLoad to set phi0surf ;
501      update output of tutorial_global_oce_in_p (affected @ truncation level).
502    o Freshen up a bit hs94.1x64x5, notably:
503      remove rotationPeriod and tRef=5*0. (adjoint only), and add
504      exactConserv=.TRUE.
505    o pkg/generic_advdiff:
506      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
507      applies to files where Temperature & Salinity 2nd Order moments are used.
508    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
509      this uses a dynamically allocated internal state data structure
510      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
511      and requires a fortran 90 compiler
512    
513    checkpoint59q
514    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
515       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
516    o Refresh tutorial_global_oce_biogeo, notably:
517      - change bathymetry (put back seamounts in ACC, use hFacs)
518      - change EOS (POLY3 --> JMD95Z)
519      - use Bryan-Lewis vertical diffusivity
520      - use multidimensional advection
521      - remove old virtual virtual in dic pkg, now done through ptracer pkg
522      - change a couple of parameters in dic pkg
523    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
524    o pkg/obcs: change default to OBCSfixTopo = .true.,
525      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
526      - replace "debugMode" with "debugLevel .GE. debLevB"
527    o implementation of TAF directives for gchem,cfc,dic
528    o remove "exp5" (replaced by tutorial_deep_convection).
529    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
530      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
531      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
532      --> changes results in exp4, seaice_obcs
533    o tutorial_deep_convection :
534      update the set-up and increase resolution and domain size ; start
535      from pseudo initial conditions = output at t=120mn in order to see
536      something happening when running testreport.
537    o pkg/seaice: add os7mp as an advection scheme
538                  add check for advection schemes
539                  add a flag for restoring T and S underneath sea ice
540    o pkg/my82: add netcdf-support and diagnostics
541    o thsice pkg:
542      - Now hsMax limits snow height by turning it into ice following
543        flooding scheme (and now conserving energy)
544      - Slight rewriting of the formula in thsice_calc_thick.F
545      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
546      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
547    
548    checkpoint59p
549    o gchem / dic / cfc :
550      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
551      - add new parameter files: "data.dic" & "data.cfc" ;
552      - various re-arrangement in initialisation & header file ;
553      - fix tutorial_global_oce_biogeo for multi-threaded test.
554    o pkg/dic: test for "pickup_dic" file when restarting ;
555      if no pickup-file, can restart with a re-initialised pH (same as it did
556      before) providing pickupStrictlyMatch is set to False.
557    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
558      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
559    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
560      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
561    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
562     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
563       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
564    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
565       scheme to use for vorticty-term ;
566     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
567       (with default selectVortScheme, return to original discretisation)
568     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
569    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
570    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
571      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
572      also fix diagnostics VISCAHW & VISCA4W.
573    
574    checkpoint59o
575    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
576    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
577      move a few statemens out the main loop into separate loops
578    o pkg/shelfice:
579      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
580        (kg/m^2/s), does not break tests, because in verification/isomip,
581        rhoConstFresh=rhoConst (by accident)
582      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
583      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
584        new file model/src/seawater.F, so that they are available for all pkgs.
585      - convert potential temperature into in-situ temperature. This changes the
586        isomip tests => update tests
587    o add a flag writePickupAtEnd (default=true) to be able to suppress
588      writing a pickup at the last timestep
589    o tools/mpack-1.6 :
590      - disable automake (not working) and autoconf (not needed).
591      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
592        also cleaner with much less compilation warnings.
593    o pkg/profiles:
594      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
595      (for "less than 32 characters name" compiler requirement)
596    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
597      conditions that have a different sampling frequency than S/T/U/V obcs
598    o pkg/diagnostics (stats-diags):
599      - fix global Min/Max in case 1 processor get only empty tiles
600    o genmake2: replace (4 times)
601         make genmake_tc_1.o >> genmake_warnings 2>&1
602      with
603         COMM="$CC $CFLAGS -c genmake_tc_1.c"
604         echo $COMM >> genmake_warnings
605         $COMM >> genmake_warnings 2>&1
606      to make genmake2 always see the value of CC as specified in the optfile.
607    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
608      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
609      - modify verification advect_cs test to test SOM-advection on CS-grid.
610    o pkg/ctrl:
611      - Rewrite of ctrl_map_ini_ecco.F,
612        introducing a generic routine (ctrl_map_ini_gen.F).
613      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
614    
615    checkpoint59n
616    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
617      number in dedicate array "hdiag":
618      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
619        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
620      - many small changes (integer format) for large number of diagnostics
621      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
622        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
623    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
624      usingSphericalGrid, this allows to define the rotated grid coordinates
625      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
626      geographical coordinates according to the inverse of the rotation defined
627      by the Euler angles, so that Coriolis parameter and online-interpolation by
628      exf works with the geographical coordinates on XC/YC/XG/YG.
629      Naturally, this feature does not work with all packages, so some
630      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
631      profiles), because there the coordinates are assumed to be regular
632      spherical grid coordinates.
633    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
634      - introduce isopycnal diffusion coefficient control.
635    o tools/adjoint_options:
636      - additional control vector components.
637    o pkg/mnc: have mnc create marginally meaning full coordinate variables
638      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
639    o pkg/mypackage:
640      - add example of read/write pickup for state-var ;
641      - add entry points to the main code for state-vars diags & write-pickup.
642    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
643      transitions for useExfYearlyFields
644      - add new subroutine that determines the file to read from for
645        use*YearlyFields = .TRUE. and .FALSE.
646      - add a verification experiment to global_with_exf that tests
647        useExfYearlyFields with USE_EXF_INTERPOLATION defined
648    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
649      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
650      subroutines (which could be generated from a template, because they are
651      almost identical), for now they are included in obcs_prescribe_read.F for
652      simplicity
653    o pkg/exf:
654      - add a little more diagnostic to exf_interp_read (in analogy to
655        mds_read_field, can be turned off with debugLevel < debugLevA=1)
656      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
657        ugly but fast by unrolling short inner loops, inserting a unroll=8
658        directive in routine lagran, and splitting a loop and making do while the
659        outermost loop (the latter requires the intoduction of index arrays)
660    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
661    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
662      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
663    o verification/seaice_obcs: updated for restart test and latest options
664    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
665      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
666      for now this is only available for the C-grid code and also within
667      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
668    
669    checkpoint59m
670    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
671      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
672    o gad_som : fix flux output (& diagnostics) to have same units as other  
673      advection scheme fluxes (was previously multiplied by deltaT).  
674    o added verification/seaice_obcs both to test seaice open boundaries
675      and to provide an example matlab scrpt for generating them
676    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
677    o pkg/salt_plume: clean up salt_plume_frac.F to
678      remove redundancy in PlumeMethod 1 and 4
679    o pkg/kpp: added saltplume diagnostics
680    o pkg/obcs and pkg/seaice:
681      - do not set uice and vice to zero when OB*icefile are unspecified
682      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
683      - moved seaice tracer obcs after call to seaice_growth
684    o pkg/salt_plume: added various options for salt plume depth
685      criterion and for vertical distribution of the salt
686    
687    checkpoint59l
688    o pkg/ptracers: new version of ptracers pickup:
689      read meta file and write only fields which are needed to restart.
690      ( same logic as main pickup file ; also using pickupStrictlyMatch )
691    o pkg/seaice:
692      - add timescale for melting due to warm mixed layer as a means of
693        setting SEAICE_availHeatFrac more conveniently
694      - add a CPP-flag/runtime parameter check for flooding algorithm
695      - reformulated availHeat in seaice_growth.F to be independent of AREA
696    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
697      unit changes
698    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
699    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
700      SX vector computer.
701    o pkg/seaice:
702      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
703        seaice forcing fields can now be read only through pkg/exf
704      - removed some unused halos
705    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
706    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
707      or U/VICE from U/VWIND before computing U/VSTRESS
708    
709    checkpoint59k
710    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
711      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
712    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
713      all experiments pass when compile with un-initialised var. checking option.
714    o added pkg/salt_plume
715    o script to test restart (for now, in MITgcm_contrib/jmc_script)
716    o pkg/seaice: new read/write pickup version.
717      read meta file and write only fields which are needed to restart.
718      ( same logic as main pickup file ; also using pickupStrictlyMatch )
719    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
720    o lab_sea.hb87: modify the domain & update output.hb87.txt :
721      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
722      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
723      process. Fixed here by closing the domain at the Northern boundary.
724    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
725    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
726      a set of consecutive levels in/from a 3-D array.
727    o pkg/ptracers:
728      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
729      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
730    
731    checkpoint59j
732    o in pkgs: dic, obcs, offline, rbcs:
733      standard way to compute coeff. for time interpolation between 2 time reccords
734      which retains full precision (& make results less dependent on compiler).
735      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
736    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
737      packages instead of reading ice cover and wind speed separately
738    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
739     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
740      to allow to compile customized code before the update)
741    o cleaning-up:
742      - fix CPP instruction syntax in pkg/obcs
743      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
744        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
745      - fix some threads issue in IO parts.
746    o pkg/dic:
747      - add tons of "_d 0" (--> much better testreports !)
748       and then update outputs of tutorial_global_oce_biogeo
749    o pkg/mom_fluxform:
750      add a special version of momentum advection intended to conserve momentum
751      next to a bathymetry step or a coastline edge. (default = off = #undef)
752    o new read/write pickup version:
753      - for now, only implemented for main (mdsio) pickup file.
754      - write out only what is needed to restart; merge pickup_nh , pickup_ph
755        and main pickup together.
756      - read meta file; read only what is needed to restart; stop if a field
757        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
758        if it make sense (even if the restart is not perfect).
759      - if no meta file, assume that pickup to read corresponds exactly to
760        a pickup that would currently be written.
761      - read pickup written in the old format (until checkpoint59i) if it
762        recognizes an old meta file (no field-list).
763      - add a meta file in exp. which starts from a pickup: 2 cases:
764        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
765         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
766        b) a meta file describing the content of the associated pickup file
767         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
768    o pkg/mdsio & pkg/rw:
769      - new routine to read a meta file ; new set of routine to read
770        Multiple-fields file (with meta file).
771    o added open boundary conditions capability for seaice
772        HSNOW, HSALT, UICE, and VICE
773    
774    checkpoint59i
775    o adjoint:
776      * fix multiDimAdvection adjoint
777        (partial recomputation problem by TAF for fVerT(:,:,kDown)
778        and comlev1 size definition (maxpass vs. max. number of tracers)
779      * verification/global_ocean.90x45x15 adjoint now tests
780        NLFS and multiDimAdvection using DST3 (=30)
781      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
782    o pkg/kpp: add "_d 0" to real constant (if missing);
783      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
784      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
785    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
786      for internal parameters related to restart process (formerly from PARAMS.h)
787      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
788    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
789      as argument. (only atm2d & obcs write_pickup have not yet been updated)
790    o pkg/monitor:
791      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
792      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
793      - account for deep Atmosphere factor and density factor (anelastic)
794    o added open boundary conditions capability for seaice HEFF and AREA
795    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
796      thermodynamics
797      - requires a little reorganization, which affects the testreport results
798        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
799        so that now the conservative form is tested
800      - add a few comments
801    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
802    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
803    o add new diagnostics to seaice: advective, diffusive fluxes (only for
804      multidim-advection, for scheme 2 they are not filled) and transports,
805      thermodynamic growth rates
806    o change units of EmPmR (inside the code, + within coupling interface)
807      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
808      Affects results @ truncation level (cg2d match) and update output of
809       experiments: lab_sea(6), global_ocean.90x40x15(10),
810      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
811      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
812      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
813      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
814    
815    checkpoint59h
816    o pkg/exf:
817      - improve vectorization by moving if-statement out of loops in
818        exf_mapfields, exf_radiation
819      - exf_bulkformulae.F: introduce 2D fields and vectorize code
820    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
821    o testreport:
822      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
823        monitor & update offline_exf_seaice exp. output.
824      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
825    o pkg/seaice:
826      - bug fix in the evp solver: boundary conditions were affected be
827        masking of zMax/zMin (changes results)
828      - minor bug fix in boundary conditions in seaice_calc_strainrates
829        (changes results for no_slip)
830      - seaice_lsr.F: make interpolation of eta dependent on boundaries
831      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
832      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
833        stress formulation and no-slip boundary conditions
834    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
835      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
836    o pkg/seaice: a first HSALT time stepping equation has been checked in
837    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
838      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
839      without requiring DO-IF statements
840    o pkg/thsice:
841      use continuous power-law function for partition of energy between lateral
842      melting/freezing and thinning/thickening ; old code using step function
843      still available with #undef THSICE_FRACEN_POWERLAW
844      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
845    o testreport: change AD testing : check against results/output_adm.txt
846      using same scripts as for forward test.
847    
848    checkpoint59g
849    o adjoint testing: in preparation for changing testreport:
850      - output format: cost and grad written on separated lines
851      - ad output results in directory "results" (instead of "results_ad")
852    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
853    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
854    o pkg/ecco: allow user defined cost function contributions
855    o testreport:
856      Allow to choose (per experiment) the list of tested output variables
857       and the main variable (used to issue a pass/FAIL ) ;
858      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
859      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
860      Also modify printing of summary:
861       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
862       b) echo the list of tested variables in the individual summary.txt of
863          each experiment.
864    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
865      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
866      (but still depend on the tile decompostion of the domain).
867    o pkg/seaice: change a discretization detail to make the B-grid code
868      "more symmetric". This change is likely to remove all "ridges/leads" that
869      where quasi-aligned with the grid in B-grid solutions. It may also be
870      the solution to the stress coupling issues with the B-grid.
871    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
872      remove .cvsignore from input dir. (since testreport no longer run here).
873    o pkg/thsice:
874     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
875     - fix reshaping of sea-ice just after advection:
876       melt all the ice only if ice-volume is too small.
877     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
878       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
879     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
880    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
881      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
882    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
883      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
884      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
885      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
886      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
887      -> update output.txt
888    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
889     this affects truncation error: -> update output.txt of exp:
890      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
891      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
892    
893    checkpoint59f
894    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
895    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
896      a bounded range (in forward mode)
897    o pkg/ecco, ctrl, autodiff and mom_common:
898     internal parameter controls, completements of implementations
899    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
900    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
901      (not seem any difference in testing results).
902    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
903       at face corners.
904    o pkg/generic_advdiff:
905     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
906      loop range indices for computing vertical advection tendency
907      and do the calculation in the interior only (no overlap) ;
908      for now, only implemented for SOM advection (to save CPU time).
909     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
910    o exch2 adjoint
911      First set of changes:
912      - add exch2 hand-written adjoint templates
913      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
914        This will require cleanup in pkg/autodiff/*.F
915        (changed routines currently kept separate in verif. code/)
916      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
917        that used to hide exch2 or cubed-sphere specific code
918        (commented via 'cph-exch2')
919    o pkg/seaice
920      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
921    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
922       output of global_ocean.cs32x15.thsice .
923    
924    checkpoint59e
925    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
926      for B-grid vector (not yet tested) and C-grid vector (<- only used
927      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
928    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
929      (#ifdef ALLOW_SALT_PLUME)
930    o gather_2d/scatter_2d: removed halo regions
931    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
932      scheme and the corresponding test case (under front_relax dir). For now,
933      only available with Skew-flux form and not yet tested in realistic set-up.
934      adjoint: store directives updated, but gradient checks deteriorated,
935      so maybe GM/Redi adjoint is now broken.
936    o seaice adjoint
937      * add AREA, HEFF, HSNOW as control variable
938        (should not change lab_sea results)
939      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
940    o pkg/seaice:
941      * added computation of saltFlux in seaice_growth;
942        For time being, sea ice salinity is assumed constant
943        contribution of snow flooding to freshening of sea ice is neglected.
944        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
945        defaults to 0.0 in order to maintain backward compatibility.
946        Typical values for SEAICE_salinity are 4 to 10 g/kg.
947      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
948      * added SEAICE_availHeatFrac, which specifies fraction of surface level
949        heat content used to melt or grow ice
950      * commented out cap of HICE: it helps keep ice thinner
951      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
952      * applied OBCS T/S mask to HEFFM sea ice mask
953    
954    checkpoint59d
955    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
956     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
957     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
958    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
959     and change default value of parameter "GM_Small_Number";
960     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
961       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
962       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
963    o pkg/ecco: cost function when applying pkg/smooth to controls
964    o pkg/ctrl: add forcingPrecond run time parameter
965    o pkg/seaice:
966     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
967     - fix bug in metric terms of u-equation in LSR solver (implicit part),
968       changes verification/lab_sea
969     - rearrange implicit part of u-equation in LSR solver to make it easier to
970       read, understand, and debug. This causes changes at the truncation level.
971     - fix (serious) bug in the boundary conditions (sign error in the implicit
972       part) of the LSR solver. Changes all LSR results.
973     - fixed problem with HSNOW initialization to avoid thick snow when AREA
974       is initilized with small values - does not change lab_sea results.
975     - added HsnowFile initialization capability
976    o pkg/smooth: addition to model/src and pkg/ctrl so allow
977     initialization of pkg/smooth and application to control vector
978    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
979    o dependencies: pkg/profiles requires pkg/cal
980    o pkg/profiles:
981     - added option ALLOW_PROFILES_GENERICGRID
982         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
983         that interpolation information (grid points and coefficients) is provided
984         within the netcdf input files.
985         -> sample matlab scripts can be found in MITgcm_contrib/gael
986         that allow you to prepare netcdf input files.
987     - also modified: cleaner include statements, cleaner error print statements,
988       cleaner stops when error, and more tests of the netcdf input files consistency.
989    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
990    o pkg/seaice:
991     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
992       requires a new routine: seaice_diagnostics_fill.F
993     - make sure that seaice does not move if not forced (pressure replacement
994       method, Hibler and Ip, 1995), changes results
995     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
996     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
997       It is turned off by default (=-1.), because it changes the results.
998     - make it possible to read AREA from a file, too.
999    
1000    checkpoint59c
1001    o add S/R and diagnostics for oceanic mixed-layer depth
1002    o move GMRedi call after all vertical mixing schemes (including KPP)
1003    o pkg/thsice:
1004     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1005      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1006    o pkg/obcs:
1007     - bug fix for balance code
1008    o pkg/seaice:
1009      - allow values of SEAICE_elasticParm > 1
1010      - add new parameter SEAICE_evpTauRelax as an alternative
1011        to SEAICE_elasticParm
1012      - make lsr boundary conditions free slip (by default), changes result
1013      - add code for no slip boundary conditions for lsr
1014      - set minimum of zeta to zero (and not 4e8) (changes results)
1015      - add a cap on AREA after advecting AREA if seaice_growth is not called
1016    o change calculation of Visbeck K:
1017      - no longer depend on tapering scheme; instead, compute slope (limited
1018        by GM_maxSlope). this is equivalent to what was comuted before with
1019        clipping or linear tappering.
1020      - fix vertical averaging (wrong by 1/2 level)
1021      - leave the old version (but will not be maintained) within
1022        #ifdef OLD_VISBECK_CALC / #endif
1023      - update output of exp. ideal_2D_oce
1024    o change error catch in calc_r_star to improve vectorization
1025    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1026      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1027    o adjoint:
1028      Re-organized adjoint checkpointing according to Matt Mazloff
1029      (but with modifs/completions/cleanups)
1030      Storing is now bundled into large arrays to optimized I/O
1031      (and second step in cleanup of the_main_loop)
1032    
1033    checkpoint59b
1034    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1035      - export/import (between ocean & coupler) fields needed for ocean DIC.
1036    o pkg/seaice:
1037      - get rid of three more exchanges seaice_calc_viscosities (required
1038        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1039      - bug fix in seaice_ocean_stress (update of lab_sea required)
1040      - reduce loop boundaries to necessary minimum also in seaice_evp
1041      - go back to the old way of computing deltaC/Z as the adjoint likes that
1042        better
1043    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1044      passive tracer to an Age Tracer) + update output.txt
1045    o pkg/exf:
1046      - implement A-grid / C-grid selection for wind-stress input files.
1047      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1048      for now, in exf_bulk_largeyeager04.F only :
1049      - change implementation for case where windspeed + 2. components wind-stress
1050        are read-in. AND use rhoConstFresh to convert evap.
1051    o pkg/seaice:
1052      - use correct EXCH_UV for wind-forcing (on A-grid).
1053      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1054        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1055    o pkg/exf:
1056      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1057      EXF_INTERPOLATION:
1058      - merge global_with_exf/code version of exf_interp_read.F
1059        to the main code ;
1060      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1061        reading the file ; Important: This options needs to be defined to recover
1062        previous code.
1063        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1064      - no longer loose real*8 precision along the way when using exf_iprec=64.
1065    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1066      - change discretisation of evp-solver in order to avoid another exchange
1067        (changes lab_sea) and clean up a little
1068      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1069        help the adjoint (this also changes the results slightly)
1070      - add a few "_d 0" where they had been missing in seaice_evp.F
1071      - cleaning up: remove unused seaice_calc_rhs.F
1072    o pkg/exf: some cleaning-up:
1073      - change various "constants" into runtime parameters
1074      - cleaned-up Large&Yeager04 routine which should eventually
1075        replace exf_bulkformulae.F (changed names of S/R and CPP)
1076        and merged various ALLOW_ATM_WIND options
1077     only used with thsice pkg (in thsice_get_exf.F):
1078      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1079        which are used when useStabilityFct_overIce=TRUE (= the default)
1080      - change default values of ice & snow emissivity and scale downward LW
1081        by ice & snow emissivity.
1082    o pkg/thsice:
1083     fix few little problems, in thsice_calc_thickn.F:
1084      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1085      - melt only laterally if hIce < hThinIce (as the comments say)
1086      and in thsice_extend.F:
1087      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1088      - start to form ice as soon as the minimum ice-volume is reachable.
1089     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1090      and cpl_aim+ocn
1091    o pkg/kpp
1092     - move computation of surface related input fields to KPP into a new
1093       subroutine kpp_forcing_surf.F
1094     - remove wrong (within bi,bj loops) EXCH calls.
1095     - little cleaning (add argument myThid in last position, cvs header ...)
1096     - for now, fix conservation problem by exchanging KPPviscAz (may not
1097       be the best fix)
1098    o pkg/seaice
1099     - check for inconsistent evp parameter/cpp-flag combination
1100     - remove leftover errIO flat for obsolete name list error handling
1101    o OpenAD
1102     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1103    
1104    checkpoint59a
1105    o pkg/seaice: some parameter clarifications and a little bit of clean up
1106    o pkg/thsice: rename run-time parameters:
1107       himin       -> hIceMin
1108       himin0      -> hThinIce
1109       hihig       -> hThickIce
1110       i0          -> i0swFrac
1111       transCoef   -> bMeltCoef
1112       frac_energy -> fracMelting
1113      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1114       with default values (for now) that do not change the results.
1115      remove old version of thsice vars advection in pkg/seaice.
1116    o in FFIELDS.h:
1117      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1118      - make pLoad & sIceLoad always available (but still only used if
1119         ATMOSPHERIC_LOADING is #define).
1120    o pkg/kpp: replaced _KPP_RL with _RL
1121    o bug fixes for vertical diffusivity computations when both KPP and
1122        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1123        are no longer updating the vertical diffusivity array
1124        (passed as argument) but are (re-) setting those arrays.
1125    o pkg/seaice: fix bug in evp solver, while doing that
1126      - change (improve?) discretization of stress computations for both
1127        cgrid-lsr and evp solver
1128      - add a new routine to compute strain rates
1129      - the above changes lab_sea results
1130      - add no slip conditions for evp solver (off by default), lsr-version
1131        may follow
1132      - fix exchange for shear at Z-points (does not change lab_sea)
1133      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1134        (to force the user to pick a time step since there is not "safe" way
1135        of choosing it)
1136      - add principal stress diagnostics
1137      - rearrange fields for evp a little to avoid having to call a: too many
1138        exchanges and b: exchanges for stress trensor components which we do
1139        not have.
1140      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1141        of evp, complete rewrite for lsr case (latter is does not yet work
1142        in all cases)
1143    o pkg/kpp: add code to have mixing in shelf ice caverns
1144      - add myThid to all kpp routines (long overdue)
1145    
1146    checkpoint59
1147    o pkg/exf:
1148      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1149        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1150      - move exf header files from lower_case.h to UPPER_CASE.h ;
1151        add missing cvs Header & Name
1152      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1153      - add namelist param. selectStressGridPosition, exf_monFreq
1154      - retire many _CLIM routines, and remove data.exf_clim
1155        + params moved to data.exf
1156        + climsst, climsss now handled by exf_set_gen, i.e.
1157          climss?period=0 refers to constant field,
1158          climss?period=-12 to monthly forcing
1159      - split up namelists in data.exf
1160    o pkg/seaice:
1161      - remove seaice_exch and seaice_exch_uv
1162      - remove superfluous exchange of theta
1163      - add myThid to seaice_budget_ocean/ice
1164      - add new interface for atmospheric wind forcing (C-grid only)
1165        + new routine
1166        + two new field (taux, tauy for stress over ice)
1167        + removed one global field (DAIRN) for C-grid case only
1168    o pkg/thsise
1169      - 2nd set of modifs for thsice adjoint in conjunction with exf
1170    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1171    
1172    checkpoint58y_post
1173    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1174      vertical diffusivity, similar to that in MOM4; turned on using
1175      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1176      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1177    o Added capability for 3D specification of background vertical diffusion
1178      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1179      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1180      "data" file that contains the 3D vertical diffusivity coefficients.
1181    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1182      - add code within pkg thsice to advect & diffuse sea-ice fields
1183      similar to (and will replace) what has been added in  seaice_advdiff.F,
1184      but: - conserving Mass, Heat & Salt.
1185           - better when using non-linear advection scheme (not yet fully tested)
1186           - can also be used in atmospheric set-up (for now, only the diffusion).
1187    
1188    checkpoint58x_post
1189    o IO option for global-file compact format:
1190      - add options when generating topology (utils/exch2/matlab-topology-generator)
1191      - add I/O capability (pkg/mdsio).
1192      - adapt utils/matlab/rdmds.m to read this format.
1193      for now long-line format not yet supported by pkg/mdsio (& exch2).
1194    o shelfice: add a few diagnostics
1195    
1196    checkpoint58w_post
1197    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1198      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1199      (and replace horiVertRatio in NH code).
1200      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1201                         and tutorial_plume_on_slope (sensitive to truncation)
1202    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1203      directly to drive seaice model (C-grid only)
1204    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1205     - reintroduce computation of wind from stress,
1206     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1207       mass points to avoid tau = 0
1208     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1209    o rdmnc.m: make it work with "global" files created with gluemnc
1210    o rdmnc.m : some improvements in dealing with singleton dimension
1211      (tested on all testreport mnc output files).
1212    o genmake2: disable pkg/profiles if netcdf test fails.
1213    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1214    o move call to cal_readparms up to make calendar parameters/variable available
1215      to all packages
1216    
1217    checkpoint58v_post
1218    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1219      useDynP_inEos_Zc tested.
1220    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1221    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1222      and portions thereof.  See read_cs.txt for description and examples.
1223    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1224      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1225      following the great-circle arc between those 2 points.
1226    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1227      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1228    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1229     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1230     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1231     - still needs work (not working with some options ; efficiency to improve)
1232       and serious testing.
1233     - use this scheme for temperature & salinity in 2 advection test exp.:
1234       advect_xy & advect_xz, respectively.
1235    
1236    checkpoint58u_post
1237    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1238    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1239    o testreport: add option "-skipdir" to skip some test.
1240    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1241      momentum calculation.
1242    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1243    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1244      remove checkpoint.F and the_correction_step.F (no longer used);
1245      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1246    o add option (linFSConserveTr) to correct for tracer source/sink due to
1247      Linear Free surface
1248    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1249    o pkg/thsice: fix reading mnc-pickups
1250    
1251    checkpoint58t_post
1252    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1253    o pkg/mdsio:
1254     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1255       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1256       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1257     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1258     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1259       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1260     - new S/R (to replace MDSWRITEMETA), which allows to write more
1261       informations (variable names, time ...) to meta files.
1262     - modify rdmds.m to give back the meta file content.
1263    o pkg/diagnostics: change vertical interpolation to be safer, and more
1264       flexible (define p-levels to interpolate to in data.diagnostics);
1265      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1266       diagnostic pointer.
1267    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1268    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1269    o fix multi-category seaice:
1270     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1271       SEAICE_MULTICATEGORY
1272     - fix short wave heat flux
1273    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1274       and allow to use EVP solver. Change forward lab_sea: test both EVP
1275       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1276    o Initial check-in of lab_sea adjoint
1277      (very similar to natl_box_adjoint/code_seaice)
1278      * used C-grid and EVP solver
1279      * used KPP, GM/Redi
1280      * uses inAdExact=.TRUE.
1281      * gradient checks fail for both ADM and TLM
1282        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1283        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1284        issue is related to forward mismatch between g77 an ifort
1285    o pkg/seaice: overhaul of thermodynamics
1286     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1287     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1288     - move a few global fields out of SEAICE.h into seaice_growth.F and
1289       make them 2D (FICE/QNETO/ ...)
1290     - remove FO (it is the same as QNETO)
1291     - introduce a few local fields to avoid modifying external fields such
1292       as atemp, etc.
1293    
1294    checkpoint58s_post
1295    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1296      changed exf_set_gen.F so that
1297        genperiod=0 means input file is one time-constant field and
1298        genperiod=-12 means input file contains 12 monthly means
1299  o CG2D: use pre-computed solver main-diagonal (stored in common block);  o CG2D: use pre-computed solver main-diagonal (stored in common block);
1300    this affects truncation error ; generate new output file for exp. which    this affects truncation error ; generate new output file for exp. which
