4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/diagnostics:
8      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
9    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
10    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
11      To avoid mixing type (RS/RL) of input/output array argument,
12      replace single mixed-type array with a pair from each type (RS/RL).
13    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
14      is now implemented for all pkgs (previously only done for the main pickup)
15    
16    checkpoint61u
17    o pkg/obcs:
18      - change OB?eta from _RS to _RL and put them into a separate commen block
19      - add code to read OB?eta from a file via obcs_prescribe_read: the code
20        compiles and does not destroy any other experiments, the data is read
21        properly, but the code is not tested in actual applications
22    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
23      create a meaningful unit attribute for the time coordinate variable
24    o pkg/ebm: add plenty of missing "_d 0" ;
25       update results of experiment global_ocean_ebm (fwd + adjoint tests)
26      Notes: several pieces of code only works for (very) specific set up
27       (domain size, lat range, etc ...); should be documented & stop if one
28       of those assumptions is not meet.
29    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
30       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
31          and offline_exf_seaice (seaicetd + adjoint).
32    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
33       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
34        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
35    o few changes to pass when compiling with strick checking of arguments
36       across S/R (allow to find few bugs in S/R calls).
37    o pkg/seaice:
38     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
39       2d-fields, for slightly better performance
40    
41    checkpoint61t
42    o pkg/seaice:
43     - remove unused variables in seaice_evp
44     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
45    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
46       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
47       each processor opens a different file (a fix from Matt).
48    o cg2d:
49       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
50       this reduces number of EXCH calls by 2 when using exch2.
51       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
52       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
53    o pkg/thsice:
54       add code for Near Infra-Red albedo (from Jeff)
55       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
56    o ini_model_io:
57       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
58       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
59       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
60    
61    checkpoint61s
62    o pkg/exch2 (exch2_rxN_cube*):
63       remove last BARRIER (no need to synchronise after getting data from shared
64       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
65    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
66      and generate new output (for the 2 tests) using default rotationPeriod.
67    o pkg/exch2:
68      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
69        (was already the case with AUTODIFF_EXCH2 defined)
70      - add bj in exch2 arrays and S/R.
71      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
72        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
73    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
74      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
75        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
76      - verification experiment natl_box.longstep
77    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
78      allow different versions of ifort (8 or 9) and different versions
79       of mpi (mpich or mpich2) to be used with the same optfile.
80      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
81       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
82    o pkg/seaice:
83      fix previous modif (3-level field removed) for old-pickup reading
84    
85    checkpoint61r
86    o pkg/seaice:
87     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
88      1. introduce fields for time step (N-1)
89      2. do not use levels 2 and 3 anymore (but keep them)
90      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
91         includes changes to pkg/thsice/thsice_get_velocity.F,
92         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
93         pkg/obcs/obcs_apply_uvice.F.
94     - completely remove code for leap-frog time stepping for second order
95       advection
96     - adjusted adjoint accordingly;
97       gradient checks have improved by an order of magnitude!
98    
99    checkpoint61q
100    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
101     - the boundary conditions along open boundaries are unclear, because the
102       associated masks are set to zero and are thus treated as closed when
103       applying the slip-boundary conditions.
104     - move initialisation of grid variables from seaice_init_varia to _fixed
105    o adding doc/diags_changes.txt
106    o model/src:
107      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
108       to avoid "_diags" naming if no relation to pkg/diagnostics.
109      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
110       file and only call PLOT_FIELD_XYZ if debugMode=T.
111      remove few PLOT_FIELD_XY calls outside initialisation.
112      remove few unnecessary BARRIER.
113    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
114      of salt_plume package in Southern Ocean
115    o pkg/thsice:
116     - fix hOceMxL in overlap (needed for sea-ice advection);
117       update output of experiment global_ocean.cs32x15.icedyn.
118    o pkg/seaice:
119     - make the (placeholder-)tracer IceAge a little more meaningful
120      by avoiding ridging of age due to convergent ice flow
121     - add diagnostics for surface temperature, atmospheric and oceanic
122       heat flux, and atmospheric and oceanic ice growth
123    
124    checkpoint61p
125    o eesupp (global_max & global_sum):
126     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
127     - remove starting & endding barrier (no longer needed)
128    o pkg/mdsio, writelocal:
129       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
130       (remove the STOP): uses shared buffer IO to store data from all threads
131       and then let master-thread write nThreads tiles.
132    o pkg/mdsio (read/write field):
133     - tiled IO done in 1 piece (all levels at a time);
134     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
135     - multi-threaded: allow to read/write local (non-shared) array
136       (was already working with singleCpuIO ; now works also without);
137       => no longer needs barrier call after reading a file (added inside
138       mds_read/write field).
139     - move barrier calls outside gather/scatter_2d to mds_read/write_field
140    o pkg/obcs/exf
141      - exf_getffieldrec.F: add a few ". _d 0" and
142                            add code to catch the case fldperiod = 0.  
143      - obcs_precribe_read.F: change if statements so that they match
144                              the variable type (_RL)
145      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
146        exf_iprec) as part of namelist EXF_NML_01
147    o pkg/mdsio:
148      - read/write tiled (local) files: read/write 1-level tile chunk at a time
149        (instead of segment of length sNx); expected to speed up tiled IO.
150    o pkg/exch2:
151      - take buffer copy from/to array out of S/R exch2_send/recv into new
152        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
153        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
154      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
155      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
156        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
157        including Topology header file (and common blocks).
158      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
159        remove 2nd exch call in exch2_s3d_rx (no longer needed).
160      - document S/R arg. list (+ update some comments)
161    o pkg/seaice:
162      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
163        temperature and humidity over sea ice based on climatological values.
164      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
165        of LSR (this change is expected to change the results slightly because now
166        it uses slightly difference moduli from the second last LSR solution, but
167        that is more consistent with the stress computations; this part of the code
168        is not tested in the verification experiments)
169      - fix diagnostics for flux of ice in case of B-grid
170      - turn strain rates eij and press into global fields within global
171        common block in SEAICE.h for more straighforward diagnostics
172      - fix diagnostics for principal stress components, press, zeta, eta
173        to give something meaning full
174    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
175      new output (all 4 tests) using default rotationPeriod.
176    o pkg KPP:
177      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
178      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
179        and normal grid from 1 to Nr)
180    o Fix computations of L4rdt in mom_calc_visc.F
181    o eesupp:
182      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
183      should be called before a "stop" if we know that all process are going
184      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
185    
186    checkpoint61o
187    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
188    o model/src/ini_curvilinear_grid.F:
189       compute angleSin/CosC when they are not read from a file
190    o pkg/seaice:
191       add pseudo time stepping for LSOR
192    o pkg/exch2:
193       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
194    o pkg/seaice:
195       Adding separate sea ice albedo, drag coefficients, and HO in Southern
196       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
197    o SingleCpuIO:
198       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
199    o pkg/seaice:
200       put exchanged variable in (local) common block for MPI+Multi-Threads
201       to work (necessary with exch1, and for now with exch2 too).
202    o verification: to get more experiments tested with mpi, mth and mpi+mth,
203      change tiling of:
204       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
205       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
206      update output of exp:
207       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
208       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
209      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
210                       (note: output.txt generated on faulks using only 1 tile)
211    o eesupp & mdsio (SingleCpuIO):
212     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
213       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
214       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
215     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
216     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
217       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
218    o pkg/exch2:
219     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
220       read parameter file "data.exch2" if it exists; otherwise try default regular
221       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
222     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
223       with new code (not to be used, just as a backup solution).
224     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
225       in utils/exch2/input.
226    
227    checkpoint61n
228    o eesupp & mdsio (SingleCpuIO):
229      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
230        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
231        receive real*4 array (instead of real*8) to read/write 32.bit files.
232        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
233         and remove new mapping S/R)
234    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
235      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
236        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
237        when using exch2. Add S/R to map global io-buffer to global model array.
238      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
239    
240    checkpoint61m
241    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
242      and add 3 other S/R for other types (R4,R8,RS).
243      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
244    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
245     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
246     - reduce number of macro definitions (keep only those which are used);
247       can always call directly the corrresponding S/R if needed.
248     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
249       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
250     Fixed wrong type of arg in:
251       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
252       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
253     To fix: global_sum of var in common block is wrong (multi-threaded) in:
254       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
255     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
256    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
257      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
258    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
259    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
260      edges are closed (zero depth); might happen with "blank tiles";
261      for now, disabled if using OBCS.
262    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
263      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
264    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
265      to reduce length of 1.D array print in STDOUT.
266    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
267      + use 48 tiles (16x8): this will allow to test "blank tiles".
268    o start to test MPI + multi-threaded (change testreport to skip tests
269      where number of tiles do not match).
270    o genmake2: add option "-omp" to turn on Open-MP ;
271      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
272    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
273      and keep the original tile numbering. Note: compatible with old
274      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
275    
276    checkpoint61l
277    o Overlaps had been forgotten in calculating ijk keys : fixed
278    o fix cyrus makedepend for gcc 4.4
279    o experiment fizhi-cs-aqualev20:
280      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
281      and generate new output. Note: new output is much closer to the old
282      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
283      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
284    o pkg/fizhi:
285     - change to avoid indices going deliberately over array-bounds
286     - remove unnecessary MPI stuff
287     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
288     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
289       does not go over array-bounds and therefore returns reliable output.
290     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
291       this S/R has 4 output arguments, which are used inside "get_alarm";
292       when it is called with the same variable "ndum" in place of several
293       output arguments, this produces weird side effect inside "get_alarm"
294      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
295       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
296       address) and produces error.
297    o tools/gemake2: (March 27-29 2009)
298      with option "-mpi": link *_mpi files from "MODS" dir (this is what
299      testreport does).
300    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
301    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
302       update lab_sea.lsr & lab_sea.salt_plume results
303    o pkg/seaice:
304      Major overhaul of the LSOR solver: change discretization from original
305      finite differences to finite volume. The old routine is still in the
306      file seaice_lsr.F and can be turned on with the CPP-flag
307      SEAICE_OLD_AND_BAD_DISCRETIZATION
308      Along with this change, the discretization of the strain rates is changed.
309      The same flag turns on the old discretization in seaice_calc_strainrates.F
310      All verification experiments with seaice are affected (except for
311      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
312      results by setting the above flag.
313      Further changes involve changes in defaults:
314      - ALLOW_FLOODING is defined and turned on by default
315      - SEAICEadvSnow = .true. is now the default
316      - SEAICEadvSalt = .true. is now the default
317      - SEAICEadvAge  = .true. is now the default
318      - SEAICE_clipVelocities  = .false. is now the default
319                                         (as per J. Zhang's recommendation)
320      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
321        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
322      - seaice_growth: replace computation of UG by a simple copy from wspeed
323    
324    checkpoint61k
325    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
326      seaice_lsr: fixed a few metric terms,
327                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
328                  add more debugging diagnostics
329      seaice_evp: removed superfluous many metric terms of FV discretization
330                  of stress divergence
331                  affects lab_sea, lab_sea.hb87
332      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
333                  of stress divergence for non-evp solver
334                  (this part is not tested anywhere)
335      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
336                  they were effectively only half slip
337                  affects lab_sea.hb87
338      updated all relevant verification experiments (except lab_sea//output_adm.txt
339        which was left over, but fails at level 7 & 6)
340    
341    checkpoint61j
342    o pkg/seaice: turn a few hard wired parameters into run time parameters
343    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
344      time in seconds as promised by the usints in seaice_monitor and exf_monitor

346      that are not cubed-sphere grids
347    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
348    o pkg/ctrl:
349      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
350    o non-hydrostatic (calc_gw.F):
351      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
352      update output of exp. global_ocean.cs32x15.viscA4
353    o remove backward compatibility for thetaMin,phiMin
354      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
355    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
356      interpolated wind field not only for curvilineargrid=.true., but also
357      for a rotated grid (rotateGrid=.true.)
358    o pkg/exf: add capability to bypass interpolation for runoff
359      by setting yet another CPP-flag
360    o eesupp/src, B-grid exchange:
361      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
362    o autodiff
363      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
364      allows to switch to single-prec common blocks;
365      corresponding switch occurs in tamc.h, integer isbyte
366      TAF store directivs "byte" and "kind" seem equivalent;
367      Most tamc.h have been updated correspondingly.
368    
369    checkpoint61i
370    o autodiff:
371      fix autodiff_sore/_restore indices for obcs
372      (spotted by I. Hoteit, M. Mazloff)
373    o pkg/autodiff, pkg/ctrl:
374      Add flag to reduce all tapelev I/O to single-prec.
375      In data.ctrl set
376        doSinglePrecTapelev = .TRUE.
377    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
378      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
379    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
380      real fresh water flux (not yet)
381    o pkg/mdsio & rw:
382     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
383     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
384    o pkg/flt:
385     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
386       init_fixed & ini_varia.
387     - clean-up & simplify linear interpolation S/R:
388       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
389     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
390     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
391     - add vert. coordinate & horiz. indices to output files.
392     - change vertical position in initial condition, from index to depth [m].
393     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
394       (easier to get to a curvilinear grid) ; delX,delY no longer used.
395    o pkg/ggl90: a few modifications:
396     - fix bottom boundary condition, and interpolation of KappaE
397       near top and bottom
398     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
399     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
400     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
401    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
402      (maintain temporary backward compatibility, until next checkpoint)
403    
404    checkpoint61h
405    o pkg/diagnostics with "periodic averaging diagnostics":
406      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
407    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
408    o pkg/obcs: fix loop ranges for balancing code
409    o pkg/flt:
410     - improve criteria for finding which tile owns a float.
411     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
412    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
413      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
414      with ocean biogeo)
415    o pkg/flt:
416     - do some cleaning and fix the restart ;
417     - add output.txt in flt_example/results to get this pkg tested.
418    o genmake2: add an EXTENDED_SRC option and flag.
419       for now, cannot be turned on on command line (only through genmake_local)
420    o pkg/mdsio: read/write vector:
421     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
422     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
423       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
424     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
425      (drop to 4 digits matching for grad). But this test does not look very
426      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
427    
428    checkpoint61g
429    o pkg/flt:
430      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
431       + make OPTIONS file more standard.
432      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
433      - fix _BYTESWAPIO CPP-Flag
434      - standard reading of file-parameter "data.flt"
435      - fix argument list of S/R FLT_RESTART
436      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
437    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
438    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
439      a still unfixed compiler/optimization bug
440    
441    checkpoint61f
442    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
443      update results of global_ocean.cs32x15.icedyn test.
444    o move getcon.F from model/src to pkg/fizhi.
445    o pkg/exf: add parameter for extrapolation of temp up to the surface
446       and option to prevent negative evap (in bulk_largeyeager04 only).
447    o Prather Advection scheme: fix tracer conservation for divergent flow
448      (e.g., when using NonLin Free-Surface).
449    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
450    o gmredi (Visbeck-variable-K):
451     - add more parameters to Visbeck-variable-K.
452     - use a 5 points average for dSigmaR in Visbeck-K calculation
453       (more "homogenous": same stencil and same weights as in dSigmaH)
454     - update output of ideal_2D_oce experiment.
455    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
456      (#undef REAL4_IS_SLOW)
457     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
458       coordinate variable
459     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
460       (surface forcing fields), removes some of the functionality
461     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
462     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
463       probably not all: copy _RS surface flux fields to RL field before
464       calling DIAGNOSTICS_FILL
465     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
466       real*4 (CALL EXCH_*_RS) versions.
467     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
468       (generate new output).
469    
470    checkpoint61e
471    o gmredi (Visbeck-variable-K):
472      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
473      - change computation of Visbeck-K where Slope > Smax :        
474        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
475        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
476    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
477      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
478    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
479    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
480      does not become too large (to avoid precision problems in implicit-diffusion
481      solver); update ideal_2D_oce output.
482    o pkg ggl90:
483      - in ggl90_cal.F: compute only one set of visc/diff, used to
484        step forward TKE/T/S/momentum
485      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
486        have Prandlt =1)
487    o gmredi (fm07):
488      - add lower limit on Transition layer thickness + lower limit on 1/lambda
489      - allow to set few more params from data.gmredi
490    o pkg ggl90:
491          - add missing sqrt(2) factor in computation of mixing length
492            scale in ggl90_calc.F
493            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
494    
495    checkpoint61d
496    o adjoint modifs
497      - adapt to new field rhoInSitu
498      - allow to revert from StoreDynVars2D, StoreDynVars3D
499        to individual fields
500        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
501    o store 3-D (in-situ) density in commom block (DYNVARS.h)
502     - save 1 rho computation.
503     - no longer modify T & S inland when using down_slope pkg.
504    o gad_som : allow to switch to SOM advection for T & S without corresponding
505      pickup files (using new S/R: MDS_CHECK4FILE).
506    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
507      (for useSingleCpuIO to work in multi-threaded)
508    o pkg/shelfice:
509     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
510       with SHELFICEtopoFile in data.shelfice
511     - move code for reading ice shelf topography and modifying hFacC into separate
512       subroutines of the shelfice package
513     - separate initialisation of "fixed" and "variable" variables
514     - kTopC is not (yet) replaced by kSurfC, although this is possible
515    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
516    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
517      and rename:
518      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
519      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
520    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
521    
522    checkpoint61c
523    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
524      to add mass source/sink of fluid in the interior (3-D generalisation
525      of oceanic real-fresh water flux).
526    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
527    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
528    o new pkg: down_slope
529      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
530      - presently, modify T & S inland (dwnslp_calc_rho.F).
531        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
532      - implementation for ocean in P-coords not tested.
533      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
534    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
535      (to facilitate conversion of oceanic pkg to p-coordinate).
536    o change FIND_RHO to FIND_RHO_2D :
537      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
538    o new pkg: cheapaml
539    
540    checkpoint61b
541    o exch2:
542      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
543      - no longer depend on the order sequence (N,S,E,W).
544      - 3rd exchange no longer needed (tested with 24 tiles).
545      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
546      - exch_UV_A-grid readily available (but not yet tested).
547      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
548      (both are no longer needed) in exch_uv: no effect in forward run; but
549       get truncation error differences with adjoint exch.
550    o exch2:
551     - change index-bounds storage (moved from target to local tile,
552       more intuitive this way) ; rename/remove some variables.
553     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
554    
555    checkpoint61a
556    o exch2/matlab-topology-generator:
557      fix bug in index bounds for N-S internal exchange (hard to tell if this
558      had any effect on the solution).
559    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
560      is exceeded
561    o testreport: modify syntax of awk, so that it works also with
562      awk, and not only with nawk and gawk
563    
564    checkpoint61
565    o autodiff
566      Change default for TAF usage by removing argument '-nonew_arg'
567      This changes TAF subroutine argument list (ordering of active var.)
568      Omission of this flag leads to incompatibility w.r.t. TAMC
569      To restore TAMC-compatibility, need following modifs:
570      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
571      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
572      Tested TAF version is 1.9.22
573      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
574    
575    checkpoint60
576    --->>> This is the last checkpoint for which generating the adjoint
577    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
578    --->>> by default.
579    --->>> Future checkpoints will ommit this flag by default.
580    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
581    o pkg/grdchk: Add gradient check to etan0 perturbations.
582    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
583    o pkg/autodiff: more flexibility in zeroadj.
584      model/src: modifying do_oceanic_phys.F accordingly.
585    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
586    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
587      special setup of gmredi for which the adjoint is stable
588      enough for parameter optimization.
589    o bridging the gap between eddy stress and GM.
590      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
591          along with a change in CPP option (now ALLOW_EDDYPSI).
592      -> when using GM w/ GM_AdvForm:
593          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
594          is applied either in the tracer Eq. or in momentum Eq.
595          depending on data.gmredi (intro. GM_InMomAsStress).
596      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
597      The key modifications are in model/src/taueddy_external_forcing.F
598      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
599    
600    checkpoint59r
601    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
602      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
603      fix option to read coriolis(@ cell-corner) from files with CS-grid.
604    o pkg/mnc: add some attributes to standard 1D-coordinate variables
605    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
606      mass points, when using mnc for output
607      - add runtime parameter (missing_value, missing_value_int) to override
608        default (which is the value of getcon('UNDEF'))
609    o pkg/mnc: prepare mnc for the actual use of missing values with the
610      diagnostics package: small fix in mnc_cw_readwrite.template and more
611      initialisation of never used fields
612      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
613      versions
614    o pkg/thsice/thsice_ini_vars.F added default initial values so that
615      thermodynamics sea ice solver does not blow up when some initial fields
616      are missing.
617    o move from external_forcing_surf.F to ini_forcing.F
618      the p-coord. hack consisting in using pLoad to set phi0surf ;
619      update output of tutorial_global_oce_in_p (affected @ truncation level).
620    o Freshen up a bit hs94.1x64x5, notably:
621      remove rotationPeriod and tRef=5*0. (adjoint only), and add
622      exactConserv=.TRUE.
623    o pkg/generic_advdiff:
624      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
625      applies to files where Temperature & Salinity 2nd Order moments are used.
626    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
627      this uses a dynamically allocated internal state data structure
628      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
629      and requires a fortran 90 compiler
630    
631    checkpoint59q
632    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
633       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
634    o Refresh tutorial_global_oce_biogeo, notably:
635      - change bathymetry (put back seamounts in ACC, use hFacs)
636      - change EOS (POLY3 --> JMD95Z)
637      - use Bryan-Lewis vertical diffusivity
638      - use multidimensional advection
639      - remove old virtual virtual in dic pkg, now done through ptracer pkg
640      - change a couple of parameters in dic pkg
641    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
642    o pkg/obcs: change default to OBCSfixTopo = .true.,
643      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
644      - replace "debugMode" with "debugLevel .GE. debLevB"
645    o implementation of TAF directives for gchem,cfc,dic
646    o remove "exp5" (replaced by tutorial_deep_convection).
647    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
648      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
649      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
650      --> changes results in exp4, seaice_obcs
651    o tutorial_deep_convection :
652      update the set-up and increase resolution and domain size ; start
653      from pseudo initial conditions = output at t=120mn in order to see
654      something happening when running testreport.
655    o pkg/seaice: add os7mp as an advection scheme
656                  add check for advection schemes
657                  add a flag for restoring T and S underneath sea ice
658    o pkg/my82: add netcdf-support and diagnostics
659    o thsice pkg:
660      - Now hsMax limits snow height by turning it into ice following
661        flooding scheme (and now conserving energy)
662      - Slight rewriting of the formula in thsice_calc_thick.F
663      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
664      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
665    
666    checkpoint59p
667    o gchem / dic / cfc :
668      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
669      - add new parameter files: "data.dic" & "data.cfc" ;
670      - various re-arrangement in initialisation & header file ;
671      - fix tutorial_global_oce_biogeo for multi-threaded test.
672    o pkg/dic: test for "pickup_dic" file when restarting ;
673      if no pickup-file, can restart with a re-initialised pH (same as it did
674      before) providing pickupStrictlyMatch is set to False.
675    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
676      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
677    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
678      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
679    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
680     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
681       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
682    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
683       scheme to use for vorticty-term ;
684     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
685       (with default selectVortScheme, return to original discretisation)
686     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
687    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
688    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
689      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
690      also fix diagnostics VISCAHW & VISCA4W.
691    
692    checkpoint59o
693    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
694    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
695      move a few statemens out the main loop into separate loops
696    o pkg/shelfice:
697      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
698        (kg/m^2/s), does not break tests, because in verification/isomip,
699        rhoConstFresh=rhoConst (by accident)
700      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
701      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
702        new file model/src/seawater.F, so that they are available for all pkgs.
703      - convert potential temperature into in-situ temperature. This changes the
704        isomip tests => update tests
705    o add a flag writePickupAtEnd (default=true) to be able to suppress
706      writing a pickup at the last timestep
707    o tools/mpack-1.6 :
708      - disable automake (not working) and autoconf (not needed).
709      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
710        also cleaner with much less compilation warnings.
711    o pkg/profiles:
712      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
713      (for "less than 32 characters name" compiler requirement)
714    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
715      conditions that have a different sampling frequency than S/T/U/V obcs
716    o pkg/diagnostics (stats-diags):
717      - fix global Min/Max in case 1 processor get only empty tiles
718    o genmake2: replace (4 times)
719         make genmake_tc_1.o >> genmake_warnings 2>&1
720      with
721         COMM="$CC $CFLAGS -c genmake_tc_1.c"
722         echo $COMM >> genmake_warnings
723         $COMM >> genmake_warnings 2>&1
724      to make genmake2 always see the value of CC as specified in the optfile.
725    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
726      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
727      - modify verification advect_cs test to test SOM-advection on CS-grid.
728    o pkg/ctrl:
729      - Rewrite of ctrl_map_ini_ecco.F,
730        introducing a generic routine (ctrl_map_ini_gen.F).
731      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
732    
733    checkpoint59n
734    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
735      number in dedicate array "hdiag":
736      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
737        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
738      - many small changes (integer format) for large number of diagnostics
739      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
740        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
741    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
742      usingSphericalGrid, this allows to define the rotated grid coordinates
743      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
744      geographical coordinates according to the inverse of the rotation defined
745      by the Euler angles, so that Coriolis parameter and online-interpolation by
746      exf works with the geographical coordinates on XC/YC/XG/YG.
747      Naturally, this feature does not work with all packages, so some
748      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
749      profiles), because there the coordinates are assumed to be regular
750      spherical grid coordinates.
751    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
752      - introduce isopycnal diffusion coefficient control.
753    o tools/adjoint_options:
754      - additional control vector components.
755    o pkg/mnc: have mnc create marginally meaning full coordinate variables
756      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
757    o pkg/mypackage:
758      - add example of read/write pickup for state-var ;
759      - add entry points to the main code for state-vars diags & write-pickup.
760    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
761      transitions for useExfYearlyFields
762      - add new subroutine that determines the file to read from for
763        use*YearlyFields = .TRUE. and .FALSE.
764      - add a verification experiment to global_with_exf that tests
765        useExfYearlyFields with USE_EXF_INTERPOLATION defined
766    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
767      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
768      subroutines (which could be generated from a template, because they are
769      almost identical), for now they are included in obcs_prescribe_read.F for
770      simplicity
771    o pkg/exf:
772      - add a little more diagnostic to exf_interp_read (in analogy to
773        mds_read_field, can be turned off with debugLevel < debugLevA=1)
774      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
775        ugly but fast by unrolling short inner loops, inserting a unroll=8
776        directive in routine lagran, and splitting a loop and making do while the
777        outermost loop (the latter requires the intoduction of index arrays)
778    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
779    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
780      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
781    o verification/seaice_obcs: updated for restart test and latest options
782    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
783      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
784      for now this is only available for the C-grid code and also within
785      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
786    
787    checkpoint59m
788    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
789      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
790    o gad_som : fix flux output (& diagnostics) to have same units as other  
791      advection scheme fluxes (was previously multiplied by deltaT).  
792    o added verification/seaice_obcs both to test seaice open boundaries
793      and to provide an example matlab scrpt for generating them
794    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
795    o pkg/salt_plume: clean up salt_plume_frac.F to
796      remove redundancy in PlumeMethod 1 and 4
797    o pkg/kpp: added saltplume diagnostics
798    o pkg/obcs and pkg/seaice:
799      - do not set uice and vice to zero when OB*icefile are unspecified
800      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
801      - moved seaice tracer obcs after call to seaice_growth
802    o pkg/salt_plume: added various options for salt plume depth
803      criterion and for vertical distribution of the salt
804    
805    checkpoint59l
806    o pkg/ptracers: new version of ptracers pickup:
807      read meta file and write only fields which are needed to restart.
808      ( same logic as main pickup file ; also using pickupStrictlyMatch )
809    o pkg/seaice:
810      - add timescale for melting due to warm mixed layer as a means of
811        setting SEAICE_availHeatFrac more conveniently
812      - add a CPP-flag/runtime parameter check for flooding algorithm
813      - reformulated availHeat in seaice_growth.F to be independent of AREA
814    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
815      unit changes
816    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
817    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
818      SX vector computer.
819    o pkg/seaice:
820      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
821        seaice forcing fields can now be read only through pkg/exf
822      - removed some unused halos
823    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
824    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
825      or U/VICE from U/VWIND before computing U/VSTRESS
826    
827    checkpoint59k
828    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
829      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
830    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
831      all experiments pass when compile with un-initialised var. checking option.
832    o added pkg/salt_plume
833    o script to test restart (for now, in MITgcm_contrib/jmc_script)
834    o pkg/seaice: new read/write pickup version.
835      read meta file and write only fields which are needed to restart.
836      ( same logic as main pickup file ; also using pickupStrictlyMatch )
837    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
838    o lab_sea.hb87: modify the domain & update output.hb87.txt :
839      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
840      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
841      process. Fixed here by closing the domain at the Northern boundary.
842    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
843    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
844      a set of consecutive levels in/from a 3-D array.
845    o pkg/ptracers:
846      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
847      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
848    
849    checkpoint59j
850    o in pkgs: dic, obcs, offline, rbcs:
851      standard way to compute coeff. for time interpolation between 2 time reccords
852      which retains full precision (& make results less dependent on compiler).
853      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
854    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
855      packages instead of reading ice cover and wind speed separately
856    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
857     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
858      to allow to compile customized code before the update)
859    o cleaning-up:
860      - fix CPP instruction syntax in pkg/obcs
861      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
862        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
863      - fix some threads issue in IO parts.
864    o pkg/dic:
865      - add tons of "_d 0" (--> much better testreports !)
866       and then update outputs of tutorial_global_oce_biogeo
867    o pkg/mom_fluxform:
868      add a special version of momentum advection intended to conserve momentum
869      next to a bathymetry step or a coastline edge. (default = off = #undef)
870    o new read/write pickup version:
871      - for now, only implemented for main (mdsio) pickup file.
872      - write out only what is needed to restart; merge pickup_nh , pickup_ph
873        and main pickup together.
874      - read meta file; read only what is needed to restart; stop if a field
875        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
876        if it make sense (even if the restart is not perfect).
877      - if no meta file, assume that pickup to read corresponds exactly to
878        a pickup that would currently be written.
879      - read pickup written in the old format (until checkpoint59i) if it
880        recognizes an old meta file (no field-list).
881      - add a meta file in exp. which starts from a pickup: 2 cases:
882        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
883         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
884        b) a meta file describing the content of the associated pickup file
885         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
886    o pkg/mdsio & pkg/rw:
887      - new routine to read a meta file ; new set of routine to read
888        Multiple-fields file (with meta file).
889    o added open boundary conditions capability for seaice
890        HSNOW, HSALT, UICE, and VICE
891    
892    checkpoint59i
893    o adjoint:
894      * fix multiDimAdvection adjoint
895        (partial recomputation problem by TAF for fVerT(:,:,kDown)
896        and comlev1 size definition (maxpass vs. max. number of tracers)
897      * verification/global_ocean.90x45x15 adjoint now tests
898        NLFS and multiDimAdvection using DST3 (=30)
899      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
900    o pkg/kpp: add "_d 0" to real constant (if missing);
901      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
902      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
903    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
904      for internal parameters related to restart process (formerly from PARAMS.h)
905      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
906    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
907      as argument. (only atm2d & obcs write_pickup have not yet been updated)
908    o pkg/monitor:
909      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
910      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
911      - account for deep Atmosphere factor and density factor (anelastic)
912    o added open boundary conditions capability for seaice HEFF and AREA
913    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
914      thermodynamics
915      - requires a little reorganization, which affects the testreport results
916        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
917        so that now the conservative form is tested
918      - add a few comments
919    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
920    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
921    o add new diagnostics to seaice: advective, diffusive fluxes (only for
922      multidim-advection, for scheme 2 they are not filled) and transports,
923      thermodynamic growth rates
924    o change units of EmPmR (inside the code, + within coupling interface)
925      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
926      Affects results @ truncation level (cg2d match) and update output of
927       experiments: lab_sea(6), global_ocean.90x40x15(10),
928      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
929      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
930      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
931      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
932    
933    checkpoint59h
934    o pkg/exf:
935      - improve vectorization by moving if-statement out of loops in
936        exf_mapfields, exf_radiation
937      - exf_bulkformulae.F: introduce 2D fields and vectorize code
938    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
939    o testreport:
940      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
941        monitor & update offline_exf_seaice exp. output.
942      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
943    o pkg/seaice:
944      - bug fix in the evp solver: boundary conditions were affected be
945        masking of zMax/zMin (changes results)
946      - minor bug fix in boundary conditions in seaice_calc_strainrates
947        (changes results for no_slip)
948      - seaice_lsr.F: make interpolation of eta dependent on boundaries
949      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
950      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
951        stress formulation and no-slip boundary conditions
952    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
953      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
954    o pkg/seaice: a first HSALT time stepping equation has been checked in
955    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
956      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
957      without requiring DO-IF statements
958    o pkg/thsice:
959      use continuous power-law function for partition of energy between lateral
960      melting/freezing and thinning/thickening ; old code using step function
961      still available with #undef THSICE_FRACEN_POWERLAW
962      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
963    o testreport: change AD testing : check against results/output_adm.txt
964      using same scripts as for forward test.
965    
966    checkpoint59g
967    o adjoint testing: in preparation for changing testreport:
968      - output format: cost and grad written on separated lines
969      - ad output results in directory "results" (instead of "results_ad")
970    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
971    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
972    o pkg/ecco: allow user defined cost function contributions
973    o testreport:
974      Allow to choose (per experiment) the list of tested output variables
975       and the main variable (used to issue a pass/FAIL ) ;
976      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
977      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
978      Also modify printing of summary:
979       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
980       b) echo the list of tested variables in the individual summary.txt of
981          each experiment.
982    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
983      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
984      (but still depend on the tile decompostion of the domain).
985    o pkg/seaice: change a discretization detail to make the B-grid code
986      "more symmetric". This change is likely to remove all "ridges/leads" that
987      where quasi-aligned with the grid in B-grid solutions. It may also be
988      the solution to the stress coupling issues with the B-grid.
989    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
990      remove .cvsignore from input dir. (since testreport no longer run here).
991    o pkg/thsice:
992     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
993     - fix reshaping of sea-ice just after advection:
994       melt all the ice only if ice-volume is too small.
995     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
996       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
997     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
998    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
999      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1000    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1001      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1002      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1003      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1004      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1005      -> update output.txt
1006    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1007     this affects truncation error: -> update output.txt of exp:
1008      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1009      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1010    
1011    checkpoint59f
1012    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1013    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1014      a bounded range (in forward mode)
1015    o pkg/ecco, ctrl, autodiff and mom_common:
1016     internal parameter controls, completements of implementations
1017    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1018    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1019      (not seem any difference in testing results).
1020    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1021       at face corners.
1022    o pkg/generic_advdiff:
1023     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1024      loop range indices for computing vertical advection tendency
1025      and do the calculation in the interior only (no overlap) ;
1026      for now, only implemented for SOM advection (to save CPU time).
1027     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1028    o exch2 adjoint
1029      First set of changes:
1030      - add exch2 hand-written adjoint templates
1031      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1032        This will require cleanup in pkg/autodiff/*.F
1033        (changed routines currently kept separate in verif. code/)
1034      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1035        that used to hide exch2 or cubed-sphere specific code
1036        (commented via 'cph-exch2')
1037    o pkg/seaice
1038      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1039    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1040       output of global_ocean.cs32x15.thsice .
1041    
1042    checkpoint59e
1043    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1044      for B-grid vector (not yet tested) and C-grid vector (<- only used
1045      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1046    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1047      (#ifdef ALLOW_SALT_PLUME)
1048    o gather_2d/scatter_2d: removed halo regions
1049    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1050      scheme and the corresponding test case (under front_relax dir). For now,
1051      only available with Skew-flux form and not yet tested in realistic set-up.
1052      adjoint: store directives updated, but gradient checks deteriorated,
1053      so maybe GM/Redi adjoint is now broken.
1054    o seaice adjoint
1055      * add AREA, HEFF, HSNOW as control variable
1056        (should not change lab_sea results)
1057      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1058    o pkg/seaice:
1059      * added computation of saltFlux in seaice_growth;
1060        For time being, sea ice salinity is assumed constant
1061        contribution of snow flooding to freshening of sea ice is neglected.
1062        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1063        defaults to 0.0 in order to maintain backward compatibility.
1064        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1065      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1066      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1067        heat content used to melt or grow ice
1068      * commented out cap of HICE: it helps keep ice thinner
1069      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1070      * applied OBCS T/S mask to HEFFM sea ice mask
1071    
1072    checkpoint59d
1073    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1074     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1075     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1076    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1077     and change default value of parameter "GM_Small_Number";
1078     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1079       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1080       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1081    o pkg/ecco: cost function when applying pkg/smooth to controls
1082    o pkg/ctrl: add forcingPrecond run time parameter
1083    o pkg/seaice:
1084     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1085     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1086       changes verification/lab_sea
1087     - rearrange implicit part of u-equation in LSR solver to make it easier to
1088       read, understand, and debug. This causes changes at the truncation level.
1089     - fix (serious) bug in the boundary conditions (sign error in the implicit
1090       part) of the LSR solver. Changes all LSR results.
1091     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1092       is initilized with small values - does not change lab_sea results.
1093     - added HsnowFile initialization capability
1094    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1095     initialization of pkg/smooth and application to control vector
1096    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1097    o dependencies: pkg/profiles requires pkg/cal
1098    o pkg/profiles:
1099     - added option ALLOW_PROFILES_GENERICGRID
1100         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1101         that interpolation information (grid points and coefficients) is provided
1102         within the netcdf input files.
1103         -> sample matlab scripts can be found in MITgcm_contrib/gael
1104         that allow you to prepare netcdf input files.
1105     - also modified: cleaner include statements, cleaner error print statements,
1106       cleaner stops when error, and more tests of the netcdf input files consistency.
1107    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1108    o pkg/seaice:
1109     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1110       requires a new routine: seaice_diagnostics_fill.F
1111     - make sure that seaice does not move if not forced (pressure replacement
1112       method, Hibler and Ip, 1995), changes results
1113     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1114     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1115       It is turned off by default (=-1.), because it changes the results.
1116     - make it possible to read AREA from a file, too.
1117    
1118    checkpoint59c
1119    o add S/R and diagnostics for oceanic mixed-layer depth
1120    o move GMRedi call after all vertical mixing schemes (including KPP)
1121    o pkg/thsice:
1122     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1123      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1124    o pkg/obcs:
1125     - bug fix for balance code
1126    o pkg/seaice:
1127      - allow values of SEAICE_elasticParm > 1
1128      - add new parameter SEAICE_evpTauRelax as an alternative
1129        to SEAICE_elasticParm
1130      - make lsr boundary conditions free slip (by default), changes result
1131      - add code for no slip boundary conditions for lsr
1132      - set minimum of zeta to zero (and not 4e8) (changes results)
1133      - add a cap on AREA after advecting AREA if seaice_growth is not called
1134    o change calculation of Visbeck K:
1135      - no longer depend on tapering scheme; instead, compute slope (limited
1136        by GM_maxSlope). this is equivalent to what was comuted before with
1137        clipping or linear tappering.
1138      - fix vertical averaging (wrong by 1/2 level)
1139      - leave the old version (but will not be maintained) within
1140        #ifdef OLD_VISBECK_CALC / #endif
1141      - update output of exp. ideal_2D_oce
1142    o change error catch in calc_r_star to improve vectorization
1143    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1144      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1145    o adjoint:
1146      Re-organized adjoint checkpointing according to Matt Mazloff
1147      (but with modifs/completions/cleanups)
1148      Storing is now bundled into large arrays to optimized I/O
1149      (and second step in cleanup of the_main_loop)
1150    
1151    checkpoint59b
1152    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1153      - export/import (between ocean & coupler) fields needed for ocean DIC.
1154    o pkg/seaice:
1155      - get rid of three more exchanges seaice_calc_viscosities (required
1156        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1157      - bug fix in seaice_ocean_stress (update of lab_sea required)
1158      - reduce loop boundaries to necessary minimum also in seaice_evp
1159      - go back to the old way of computing deltaC/Z as the adjoint likes that
1160        better
1161    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1162      passive tracer to an Age Tracer) + update output.txt
1163    o pkg/exf:
1164      - implement A-grid / C-grid selection for wind-stress input files.
1165      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1166      for now, in exf_bulk_largeyeager04.F only :
1167      - change implementation for case where windspeed + 2. components wind-stress
1168        are read-in. AND use rhoConstFresh to convert evap.
1169    o pkg/seaice:
1170      - use correct EXCH_UV for wind-forcing (on A-grid).
1171      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1172        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1173    o pkg/exf:
1174      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1175      EXF_INTERPOLATION:
1176      - merge global_with_exf/code version of exf_interp_read.F
1177        to the main code ;
1178      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1179        reading the file ; Important: This options needs to be defined to recover
1180        previous code.
1181        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1182      - no longer loose real*8 precision along the way when using exf_iprec=64.
1183    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1184      - change discretisation of evp-solver in order to avoid another exchange
1185        (changes lab_sea) and clean up a little
1186      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1187        help the adjoint (this also changes the results slightly)
1188      - add a few "_d 0" where they had been missing in seaice_evp.F
1189      - cleaning up: remove unused seaice_calc_rhs.F
1190    o pkg/exf: some cleaning-up:
1191      - change various "constants" into runtime parameters
1192      - cleaned-up Large&Yeager04 routine which should eventually
1193        replace exf_bulkformulae.F (changed names of S/R and CPP)
1194        and merged various ALLOW_ATM_WIND options
1195     only used with thsice pkg (in thsice_get_exf.F):
1196      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1197        which are used when useStabilityFct_overIce=TRUE (= the default)
1198      - change default values of ice & snow emissivity and scale downward LW
1199        by ice & snow emissivity.
1200    o pkg/thsice:
1201     fix few little problems, in thsice_calc_thickn.F:
1202      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1203      - melt only laterally if hIce < hThinIce (as the comments say)
1204      and in thsice_extend.F:
1205      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1206      - start to form ice as soon as the minimum ice-volume is reachable.
1207     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1208      and cpl_aim+ocn
1209    o pkg/kpp
1210     - move computation of surface related input fields to KPP into a new
1211       subroutine kpp_forcing_surf.F
1212     - remove wrong (within bi,bj loops) EXCH calls.
1213     - little cleaning (add argument myThid in last position, cvs header ...)
1214     - for now, fix conservation problem by exchanging KPPviscAz (may not
1215       be the best fix)
1216    o pkg/seaice
1217     - check for inconsistent evp parameter/cpp-flag combination
1218     - remove leftover errIO flat for obsolete name list error handling
1219    o OpenAD
1220     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1221    
1222    checkpoint59a
1223    o pkg/seaice: some parameter clarifications and a little bit of clean up
1224    o pkg/thsice: rename run-time parameters:
1225       himin       -> hIceMin
1226       himin0      -> hThinIce
1227       hihig       -> hThickIce
1228       i0          -> i0swFrac
1229       transCoef   -> bMeltCoef
1230       frac_energy -> fracMelting
1231      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1232       with default values (for now) that do not change the results.
1233      remove old version of thsice vars advection in pkg/seaice.
1234    o in FFIELDS.h:
1235      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1236      - make pLoad & sIceLoad always available (but still only used if
1237         ATMOSPHERIC_LOADING is #define).
1238    o pkg/kpp: replaced _KPP_RL with _RL
1239    o bug fixes for vertical diffusivity computations when both KPP and
1240        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1241        are no longer updating the vertical diffusivity array
1242        (passed as argument) but are (re-) setting those arrays.
1243    o pkg/seaice: fix bug in evp solver, while doing that
1244      - change (improve?) discretization of stress computations for both
1245        cgrid-lsr and evp solver
1246      - add a new routine to compute strain rates
1247      - the above changes lab_sea results
1248      - add no slip conditions for evp solver (off by default), lsr-version
1249        may follow
1250      - fix exchange for shear at Z-points (does not change lab_sea)
1251      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1252        (to force the user to pick a time step since there is not "safe" way
1253        of choosing it)
1254      - add principal stress diagnostics
1255      - rearrange fields for evp a little to avoid having to call a: too many
1256        exchanges and b: exchanges for stress trensor components which we do
1257        not have.
1258      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1259        of evp, complete rewrite for lsr case (latter is does not yet work
1260        in all cases)
1261    o pkg/kpp: add code to have mixing in shelf ice caverns
1262      - add myThid to all kpp routines (long overdue)
1263    
1264    checkpoint59
1265    o pkg/exf:
1266      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1267        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1268      - move exf header files from lower_case.h to UPPER_CASE.h ;
1269        add missing cvs Header & Name
1270      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1271      - add namelist param. selectStressGridPosition, exf_monFreq
1272      - retire many _CLIM routines, and remove data.exf_clim
1273        + params moved to data.exf
1274        + climsst, climsss now handled by exf_set_gen, i.e.
1275          climss?period=0 refers to constant field,
1276          climss?period=-12 to monthly forcing
1277      - split up namelists in data.exf
1278    o pkg/seaice:
1279      - remove seaice_exch and seaice_exch_uv
1280      - remove superfluous exchange of theta
1281      - add myThid to seaice_budget_ocean/ice
1282      - add new interface for atmospheric wind forcing (C-grid only)
1283        + new routine
1284        + two new field (taux, tauy for stress over ice)
1285        + removed one global field (DAIRN) for C-grid case only
1286    o pkg/thsise
1287      - 2nd set of modifs for thsice adjoint in conjunction with exf
1288    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1289    
1290    checkpoint58y_post
1291    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1292      vertical diffusivity, similar to that in MOM4; turned on using
1293      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1294      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1295    o Added capability for 3D specification of background vertical diffusion
1296      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1297      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1298      "data" file that contains the 3D vertical diffusivity coefficients.
1299    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1300      - add code within pkg thsice to advect & diffuse sea-ice fields
1301      similar to (and will replace) what has been added in  seaice_advdiff.F,
1302      but: - conserving Mass, Heat & Salt.
1303           - better when using non-linear advection scheme (not yet fully tested)
1304           - can also be used in atmospheric set-up (for now, only the diffusion).
1305    
1306    checkpoint58x_post
1307    o IO option for global-file compact format:
1308      - add options when generating topology (utils/exch2/matlab-topology-generator)
1309      - add I/O capability (pkg/mdsio).
1310      - adapt utils/matlab/rdmds.m to read this format.
1311      for now long-line format not yet supported by pkg/mdsio (& exch2).
1312    o shelfice: add a few diagnostics
1313    
1314    checkpoint58w_post
1315    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1316      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1317      (and replace horiVertRatio in NH code).
1318      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1319                         and tutorial_plume_on_slope (sensitive to truncation)
1320    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1321      directly to drive seaice model (C-grid only)
1322    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1323     - reintroduce computation of wind from stress,
1324     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1325       mass points to avoid tau = 0
1326     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1327    o rdmnc.m: make it work with "global" files created with gluemnc
1328    o rdmnc.m : some improvements in dealing with singleton dimension
1329      (tested on all testreport mnc output files).
1330    o genmake2: disable pkg/profiles if netcdf test fails.
1331    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1332    o move call to cal_readparms up to make calendar parameters/variable available
1333      to all packages
1334    
1335    checkpoint58v_post
1336    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1337      useDynP_inEos_Zc tested.
1338    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1339    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1340      and portions thereof.  See read_cs.txt for description and examples.
1341    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1342      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1343      following the great-circle arc between those 2 points.
1344    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1345      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1346    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1347     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1348     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1349     - still needs work (not working with some options ; efficiency to improve)
1350       and serious testing.
1351     - use this scheme for temperature & salinity in 2 advection test exp.:
1352       advect_xy & advect_xz, respectively.
1353    
1354    checkpoint58u_post
1355    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1356    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1357    o testreport: add option "-skipdir" to skip some test.
1358    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1359      momentum calculation.
1360    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1361    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1362      remove checkpoint.F and the_correction_step.F (no longer used);
1363      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1364    o add option (linFSConserveTr) to correct for tracer source/sink due to
1365      Linear Free surface
1366    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1367    o pkg/thsice: fix reading mnc-pickups
1368    
1369    checkpoint58t_post
1370    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1371    o pkg/mdsio:
1372     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1373       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1374       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1375     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1376     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1377       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1378     - new S/R (to replace MDSWRITEMETA), which allows to write more
1379       informations (variable names, time ...) to meta files.
1380     - modify rdmds.m to give back the meta file content.
1381    o pkg/diagnostics: change vertical interpolation to be safer, and more
1382       flexible (define p-levels to interpolate to in data.diagnostics);
1383      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1384       diagnostic pointer.
1385    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1386    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1387    o fix multi-category seaice:
1388     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1389       SEAICE_MULTICATEGORY
1390     - fix short wave heat flux
1391    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1392       and allow to use EVP solver. Change forward lab_sea: test both EVP
1393       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1394    o Initial check-in of lab_sea adjoint
1395      (very similar to natl_box_adjoint/code_seaice)
1396      * used C-grid and EVP solver
1397      * used KPP, GM/Redi
1398      * uses inAdExact=.TRUE.
1399      * gradient checks fail for both ADM and TLM
1400        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1401        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1402        issue is related to forward mismatch between g77 an ifort
1403    o pkg/seaice: overhaul of thermodynamics
1404     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1405     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1406     - move a few global fields out of SEAICE.h into seaice_growth.F and
1407       make them 2D (FICE/QNETO/ ...)
1408     - remove FO (it is the same as QNETO)
1409     - introduce a few local fields to avoid modifying external fields such
1410       as atemp, etc.
1411    
1412    checkpoint58s_post
1413    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1414      changed exf_set_gen.F so that
1415        genperiod=0 means input file is one time-constant field and
1416        genperiod=-12 means input file contains 12 monthly means
1417    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1418      this affects truncation error ; generate new output file for exp. which
1419      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1420        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1421        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1422        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1423        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1424        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1425    o start implementation of deep-atmosphere and anelastic formulation
1426    o verification: remove 2nd copy of input files and use script "prepare_run"
1427      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1428    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1429    o profiles: fix for multithreaded case
1430    
1431    o diagnostics: rename few diags:
1432      s/'PRESSURE'/'RCENTER '/g
1433      s/'TICE    '/'oceFreez'/g
1434      s/'TAUX    '/'oceTAUX '/g
1435      s/'TAUY    '/'oceTAUY '/g
1436      s/'SWFLUX  '/'oceQsw  '/g
1437      s/DIFx/DFxE/g
1438      s/DIFy/DFyE/g
1439      and add few ocean-forcing diagnostics:
1440      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1441    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1442      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1443      as actual snow thickness.  It now refers everywhere to effective snow
1444      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1445    
1446    checkpoint58r_post
1447    o modifications to pkg/seaice/growth.F, which change results of
1448      lab_sea experiment: fixes pertain to melting snow over open water, to
1449      masking EVAP under sea ice, and to using the correct AREA variable for
1450      computations of EVAP, PRECIP, HSNOW, and GHEFF
1451    o add ability to read bathy, salt, and theta using MNC (off by def)
1452    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1453      both are turned off by default and do no change any results
1454    o seaice advection with pkg/thsice: a step toward the use of non-linear
1455      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1456    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1457      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1458      in natl_box (affects results @ truncation level: update output.txt)
1459    o multi-threading and IO:
1460      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1461      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1462        (needed to work with SingleCpuIO): tested in all verif. exp.
1463    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1464      affects the results (but none of the verification test uses this scheme).
1465    o Adding some pkg/diagnostics capability to pkg/seaice
1466      (will certainly be subject to changes)
1467    o ctrl: adding new control variables:
1468      lwflux, lwdown, evap, snowprecip, apressure, runoff
1469    
1470    checkpoint58q_post
1471    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1472      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1473      high_res_cube configuration by 4% on Columbia.
1474    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1475      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1476      dynamical allocation (seems to work in multi-threaded).
1477    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1478      single CPU io) so that TAF does not have to see EESUPPORT.h
1479    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1480    
1481    checkpoint58p_post
1482    o obcs: stop if obcs is used with useCDscheme = .true.
1483    o shelfice:
1484     - fix a sign error so that no slip at shelfice interface works
1485     - remove stop for combination non-hydrostatic code and shelfice. That does
1486       not mean, that the results are correct, but at least they are numerically
1487       stable
1488    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1489    o added adjoint exch routined for all exch*3d* routines
1490      and updated flow directives
1491    
1492    checkpoint58o_post
1493    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1494      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1495    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1496      and clean-up reading/writing of pickup files.
1497    o fix local version of read/write pickup (NH part) in rotating_tank/code
1498    o simplify EXCH interface:
1499     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1500     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1501    o added the regrid package
1502    o shelfice:
1503     - add a simple boundary layer scheme to reduce noise
1504     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1505    
1506    checkpoint58n_post
1507    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1508       local variable (not in common block).
1509    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1510      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1511      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1512        to work with SingleCpuIO.
1513    o add "_d 0" to real constant of pkg/cfc subroutines ;
1514       update exp. cfc_exemple & tutorial_cfc_offline output files.
1515    o multi-threading and IO:
1516      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1517        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1518      - barrier before and after reading.
1519      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1520      - avoid using MDS_WRITELOCAL for LAND pkg output.
1521      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1522        common-block variables ; Allows multi-threading with master-thread IO.
1523    o change default MAX_NO_THREADS from 32 to 4 ;
1524      and stop cleanly when MAX_NO_THREADS is too small.
1525    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1526    
1527    checkpoint58m_post
1528    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1529       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1530    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1531       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1532       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1533    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1534        add MITgcm_tutorials (= code + all the tutorials)
1535    o ecco, option to compute cost for total ssh (mean+anom)
1536    o consistent with addition of ptracer and ssh in pkg/profiles
1537    o profiles: adding ptracer and ssh
1538    o testreport: change multi-test output-file name
1539      (from output.txt.{name} to output.{name}.txt)
1540    o profiles: now ok for mutli-tiles case
1541    o seaice: add 4 parameters for different advection schemes for area,
1542      (effective) seaice thickness, enthalphy, and snow height. Their default
1543      is the standard parameter SEAICEadvScheme
1544    o calc_gw:
1545     - add cosFacU in zonal viscous flux (harmonic.visc.).
1546     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1547       of tutorial_plume_on_slope.
1548    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1549    o calc_gw: true flux-form, account for horizontal grid spacing.
1550      update rotating_tank results, but not plume_on_slope (affected at
1551      truncation level, 11 digits).
1552    
1553  checkpoint58l_post  checkpoint58l_post
1554  o take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V  o calc_gw:
1555     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1556     - remove side-drag for now (need to fix it); update plume_on_slope results.
1557     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
