4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice
8     - fix diagnostics of principal stress components for EVP
9     - add optional diagnostics of non-linear convergence for LSOR solver
10     - make maximum zeta a runtime parameter
11    o model/src (3-d solver):
12      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
13       which consisted in removing the Surf. Non-Hydrostatic pressure from the
14       whole column and adding it to Eta (inspired from Casualli, 1999):
15       Only affects 3-D solver initial guess and only if using ExactConserv,
16       but tests did show a degradation of solver convergence. For this reason,
17       decide to disable this piece of code.
18       to recover previous version, just set zeroPsNH = exactConserv (line 78).
19      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
20    o pkg/ggl90:
21     - fix previous modif (unfortunatly has not been documented here).
22    o pkg/seaice/autodiff:
23     - add CPP flag to include clipping of zeta in EVP code;
24       although clipping of zeta is not necessary for EVP and not recommended
25       it was done by default, now clipping is disabled by default
26     - modify computation and store zetaC/Z in seaice_evp for TAF
27     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
28     - change seaice_calc_viscosities/strainrates for better
29       vectorization after AD by TAF
30     - rearrange common blocks in SEAICE.h once again for easier dumps of
31       adjoint output, adjust adcommon.h and g_common.h
32     - change flux form of default advection scheme for better vectorization
33       of adjoint code
34     - modify lab_sea/input.lsr to test the flux form of default advection
35       scheme
36    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
37      transition in checkpoint61r)
38    
39    checkpoint61x
40    o adjoint: adding two new verification experiments
41      * tutorial_global_biogeo: an online dic sensitivity experiment
42        (work with G. Forget)
43      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
44        (an update of the Dutkiewicz et al., 2006 paper)
45      Both use the same CO2FLUX cost function, but different controls
46      Gradient checks look good, but some recomp. could still be traightened out
47      Should add xx_dic control variable to test at some point
48    o model/src:
49      add run-time parameters to check and/or mask initial Temp & Salt
50    o pkg/ptracers:
51      apply zonal filter (if used) to all passive tracers
52    
53    checkpoint61w
54    o adjoint:
55      * update and finish work on adjoint of dic package (G. Forget)
56      * start adjoint of offline package
57      * bug fix for cube-sphere TLM code (active_file_g.F)
58    o tutorial_global_oce_optim:
59      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
60      and add SIZE.h_mpi for MPI testing
61    o pkg autodiff
62     - fix bug in autodiff_restore
63     - make genmake2 remove comments and empty lines from ad_input_code.f in
64       order to reduce file size (new script file remove_comments_sed)
65    o allows to specify vertical profile of vertical viscosity (viscArNr)
66    o pkg autodiff
67      autodiff_ini_model_io: comment out writing of grid information to netcdf
68      files, because at this time the grid fields are a bunch of zeros
69      (this is analogous to ini_mnc_vars.F)
70    o pkg seaice/autodiff:
71     left-over from removing the 3-time-level fields:
72     - small rearrangement of common blocks (SEAICE.h)
73     - fix field declaration in order to get meaningful output in
74       adseaice.*.nc (adcommon.h)
75    o pkg obcs:
76     - go through NH code only if nonHydrostatic=T
77     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
78     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
79       => Update output of experiment seaice_obcs
80     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
81     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
82     - fix restart for useOBCSprescribe + useEXF
83    o pkg ctrl
84     - make obcs as control parameter work also with useSingleCPUio
85     - replace a few sny and snx by Ny and Nx to be consistent with
86       ctrl_set_globfld_x/yz.F
87    o pkg seaice
88     - re-introduce global field frWtrAtm for the case of
89       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
90     - catch the case of an empty filename in seaice_cost_init_fixed.F
91    o pkg ecco:
92     - small bug fixes in the_main_loop
93      . fix order of monitor arguments
94      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
95      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
96        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
97     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
98       imbalance diagnostics for wmean_h/sflux = 0
99     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
100     - catch the case of empty filenames in ecco_cost_init_fixed.F
101       and ecco_readparms.F
102     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
103       to make this statement meaningfull in ecco_cost_weights.F
104    o pkg zonal_filt:
105      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
106      - when using rStar, filter uVel*hFacW instead of uVel
107       (tested without topography: fix a Pb of growing instability with NLFS)
108    o pkg/aim/thsice:
109     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
110      (works as SST restoring)
111    o pkg/thsice:
112     -add specific parameter for salt restoring in slab mixed-layer
113       (by default equal to the temperature restoring)
114    
115    checkpoint61v
116    o pkg/kpp:
117     -add double diffusive contributions as a hack, turned off by default
118      for now, and the code can be excluded with a CPP-flag
119      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
120     -add a verification experiments to "vermix" to test this code
121    o pkg/mom_common:
122      Move computation of length scales to mom_init_fixed.F (avoid recomputation
123      at each time-steps*levels).
124    o pkg/layers:
125      Created a new package for computing volume fluxes in temperature or
126      [not yet implemented] density layers, e.g. for calculating residual
127      overturning circulations.
128    o pkg/diagnostics:
129      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
130    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
131    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
132      To avoid mixing type (RS/RL) of input/output array argument,
133      replace single mixed-type array with a pair from each type (RS/RL).
134    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
135      is now implemented for all pkgs (previously only done for the main pickup)
136    
137    checkpoint61u
138    o pkg/obcs:
139      - change OB?eta from _RS to _RL and put them into a separate commen block
140      - add code to read OB?eta from a file via obcs_prescribe_read: the code
141        compiles and does not destroy any other experiments, the data is read
142        properly, but the code is not tested in actual applications
143    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
144      create a meaningful unit attribute for the time coordinate variable
145    o pkg/ebm: add plenty of missing "_d 0" ;
146       update results of experiment global_ocean_ebm (fwd + adjoint tests)
147      Notes: several pieces of code only works for (very) specific set up
148       (domain size, lat range, etc ...); should be documented & stop if one
149       of those assumptions is not meet.
150    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
151       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
152          and offline_exf_seaice (seaicetd + adjoint).
153    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
154       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
155        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
156    o few changes to pass when compiling with strick checking of arguments
157       across S/R (allow to find few bugs in S/R calls).
158    o pkg/seaice:
159     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
160       2d-fields, for slightly better performance
161    
162    checkpoint61t
163    o pkg/seaice:
164     - remove unused variables in seaice_evp
165     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
166    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
167       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
168       each processor opens a different file (a fix from Matt).
169    o cg2d:
170       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
171       this reduces number of EXCH calls by 2 when using exch2.
172       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
173       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
174    o pkg/thsice:
175       add code for Near Infra-Red albedo (from Jeff)
176       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
177    o ini_model_io:
178       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
179       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
180       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
181    
182    checkpoint61s
183    o pkg/exch2 (exch2_rxN_cube*):
184       remove last BARRIER (no need to synchronise after getting data from shared
185       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
186    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
187      and generate new output (for the 2 tests) using default rotationPeriod.
188    o pkg/exch2:
189      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
190        (was already the case with AUTODIFF_EXCH2 defined)
191      - add bj in exch2 arrays and S/R.
192      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
193        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
194    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
195      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
196        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
197      - verification experiment natl_box.longstep
198    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
199      allow different versions of ifort (8 or 9) and different versions
200       of mpi (mpich or mpich2) to be used with the same optfile.
201      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
202       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
203    o pkg/seaice:
204      fix previous modif (3-level field removed) for old-pickup reading
205    
206    checkpoint61r
207    o pkg/seaice:
208     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
209      1. introduce fields for time step (N-1)
210      2. do not use levels 2 and 3 anymore (but keep them)
211      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
212         includes changes to pkg/thsice/thsice_get_velocity.F,
213         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
214         pkg/obcs/obcs_apply_uvice.F.
215     - completely remove code for leap-frog time stepping for second order
216       advection
217     - adjusted adjoint accordingly;
218       gradient checks have improved by an order of magnitude!
219    
220    checkpoint61q
221    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
222     - the boundary conditions along open boundaries are unclear, because the
223       associated masks are set to zero and are thus treated as closed when
224       applying the slip-boundary conditions.
225     - move initialisation of grid variables from seaice_init_varia to _fixed
226    o adding doc/diags_changes.txt
227    o model/src:
228      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
229       to avoid "_diags" naming if no relation to pkg/diagnostics.
230      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
231       file and only call PLOT_FIELD_XYZ if debugMode=T.
232      remove few PLOT_FIELD_XY calls outside initialisation.
233      remove few unnecessary BARRIER.
234    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
235      of salt_plume package in Southern Ocean
236    o pkg/thsice:
237     - fix hOceMxL in overlap (needed for sea-ice advection);
238       update output of experiment global_ocean.cs32x15.icedyn.
239    o pkg/seaice:
240     - make the (placeholder-)tracer IceAge a little more meaningful
241      by avoiding ridging of age due to convergent ice flow
242     - add diagnostics for surface temperature, atmospheric and oceanic
243       heat flux, and atmospheric and oceanic ice growth
244    
245    checkpoint61p
246    o eesupp (global_max & global_sum):
247     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
248     - remove starting & endding barrier (no longer needed)
249    o pkg/mdsio, writelocal:
250       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
251       (remove the STOP): uses shared buffer IO to store data from all threads
252       and then let master-thread write nThreads tiles.
253    o pkg/mdsio (read/write field):
254     - tiled IO done in 1 piece (all levels at a time);
255     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
256     - multi-threaded: allow to read/write local (non-shared) array
257       (was already working with singleCpuIO ; now works also without);
258       => no longer needs barrier call after reading a file (added inside
259       mds_read/write field).
260     - move barrier calls outside gather/scatter_2d to mds_read/write_field
261    o pkg/obcs/exf
262      - exf_getffieldrec.F: add a few ". _d 0" and
263                            add code to catch the case fldperiod = 0.  
264      - obcs_precribe_read.F: change if statements so that they match
265                              the variable type (_RL)
266      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
267        exf_iprec) as part of namelist EXF_NML_01
268    o pkg/mdsio:
269      - read/write tiled (local) files: read/write 1-level tile chunk at a time
270        (instead of segment of length sNx); expected to speed up tiled IO.
271    o pkg/exch2:
272      - take buffer copy from/to array out of S/R exch2_send/recv into new
273        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
274        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
275      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
276      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
277        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
278        including Topology header file (and common blocks).
279      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
280        remove 2nd exch call in exch2_s3d_rx (no longer needed).
281      - document S/R arg. list (+ update some comments)
282    o pkg/seaice:
283      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
284        temperature and humidity over sea ice based on climatological values.
285      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
286        of LSR (this change is expected to change the results slightly because now
287        it uses slightly difference moduli from the second last LSR solution, but
288        that is more consistent with the stress computations; this part of the code
289        is not tested in the verification experiments)
290      - fix diagnostics for flux of ice in case of B-grid
291      - turn strain rates eij and press into global fields within global
292        common block in SEAICE.h for more straighforward diagnostics
293      - fix diagnostics for principal stress components, press, zeta, eta
294        to give something meaning full
295    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
296      new output (all 4 tests) using default rotationPeriod.
297    o pkg KPP:
298      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
299      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
300        and normal grid from 1 to Nr)
301    o Fix computations of L4rdt in mom_calc_visc.F
302    o eesupp:
303      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
304      should be called before a "stop" if we know that all process are going
305      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
306    
307    checkpoint61o
308    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
309    o model/src/ini_curvilinear_grid.F:
310       compute angleSin/CosC when they are not read from a file
311    o pkg/seaice:
312       add pseudo time stepping for LSOR
313    o pkg/exch2:
314       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
315    o pkg/seaice:
316       Adding separate sea ice albedo, drag coefficients, and HO in Southern
317       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
318    o SingleCpuIO:
319       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
320    o pkg/seaice:
321       put exchanged variable in (local) common block for MPI+Multi-Threads
322       to work (necessary with exch1, and for now with exch2 too).
323    o verification: to get more experiments tested with mpi, mth and mpi+mth,
324      change tiling of:
325       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
326       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
327      update output of exp:
328       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
329       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
330      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
331                       (note: output.txt generated on faulks using only 1 tile)
332    o eesupp & mdsio (SingleCpuIO):
333     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
334       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
335       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
336     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
337     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
338       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
339    o pkg/exch2:
340     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
341       read parameter file "data.exch2" if it exists; otherwise try default regular
342       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
343     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
344       with new code (not to be used, just as a backup solution).
345     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
346       in utils/exch2/input.
347    
348    checkpoint61n
349    o eesupp & mdsio (SingleCpuIO):
350      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
351        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
352        receive real*4 array (instead of real*8) to read/write 32.bit files.
353        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
354         and remove new mapping S/R)
355    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
356      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
357        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
358        when using exch2. Add S/R to map global io-buffer to global model array.
359      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
360    
361    checkpoint61m
362    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
363      and add 3 other S/R for other types (R4,R8,RS).
364      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
365    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
366     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
367     - reduce number of macro definitions (keep only those which are used);
368       can always call directly the corrresponding S/R if needed.
369     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
370       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
371     Fixed wrong type of arg in:
372       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
373       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
374     To fix: global_sum of var in common block is wrong (multi-threaded) in:
375       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
376     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
377    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
378      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
379    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
380    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
381      edges are closed (zero depth); might happen with "blank tiles";
382      for now, disabled if using OBCS.
383    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
384      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
385    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
386      to reduce length of 1.D array print in STDOUT.
387    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
388      + use 48 tiles (16x8): this will allow to test "blank tiles".
389    o start to test MPI + multi-threaded (change testreport to skip tests
390      where number of tiles do not match).
391    o genmake2: add option "-omp" to turn on Open-MP ;
392      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
393    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
394      and keep the original tile numbering. Note: compatible with old
395      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
396    
397    checkpoint61l
398    o Overlaps had been forgotten in calculating ijk keys : fixed
399    o fix cyrus makedepend for gcc 4.4
400    o experiment fizhi-cs-aqualev20:
401      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
402      and generate new output. Note: new output is much closer to the old
403      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
404      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
405    o pkg/fizhi:
406     - change to avoid indices going deliberately over array-bounds
407     - remove unnecessary MPI stuff
408     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
409     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
410       does not go over array-bounds and therefore returns reliable output.
411     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
412       this S/R has 4 output arguments, which are used inside "get_alarm";
413       when it is called with the same variable "ndum" in place of several
414       output arguments, this produces weird side effect inside "get_alarm"
415      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
416       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
417       address) and produces error.
418    o tools/gemake2: (March 27-29 2009)
419      with option "-mpi": link *_mpi files from "MODS" dir (this is what
420      testreport does).
421    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
422    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
423       update lab_sea.lsr & lab_sea.salt_plume results
424    o pkg/seaice:
425      Major overhaul of the LSOR solver: change discretization from original
426      finite differences to finite volume. The old routine is still in the
427      file seaice_lsr.F and can be turned on with the CPP-flag
428      SEAICE_OLD_AND_BAD_DISCRETIZATION
429      Along with this change, the discretization of the strain rates is changed.
430      The same flag turns on the old discretization in seaice_calc_strainrates.F
431      All verification experiments with seaice are affected (except for
432      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
433      results by setting the above flag.
434      Further changes involve changes in defaults:
435      - ALLOW_FLOODING is defined and turned on by default
436      - SEAICEadvSnow = .true. is now the default
437      - SEAICEadvSalt = .true. is now the default
438      - SEAICEadvAge  = .true. is now the default
439      - SEAICE_clipVelocities  = .false. is now the default
440                                         (as per J. Zhang's recommendation)
441      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
442        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
443      - seaice_growth: replace computation of UG by a simple copy from wspeed
444    
445    checkpoint61k
446    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
447      seaice_lsr: fixed a few metric terms,
448                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
449                  add more debugging diagnostics
450      seaice_evp: removed superfluous many metric terms of FV discretization
451                  of stress divergence
452                  affects lab_sea, lab_sea.hb87
453      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
454                  of stress divergence for non-evp solver
455                  (this part is not tested anywhere)
456      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
457                  they were effectively only half slip
458                  affects lab_sea.hb87
459      updated all relevant verification experiments (except lab_sea//output_adm.txt
460        which was left over, but fails at level 7 & 6)
461    
462    checkpoint61j
463    o pkg/seaice: turn a few hard wired parameters into run time parameters
464    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
465      time in seconds as promised by the usints in seaice_monitor and exf_monitor
466    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
467      that are not cubed-sphere grids
468    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
469    o pkg/ctrl:
470      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
471    o non-hydrostatic (calc_gw.F):
472      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
473      update output of exp. global_ocean.cs32x15.viscA4
474    o remove backward compatibility for thetaMin,phiMin
475      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
476    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
477      interpolated wind field not only for curvilineargrid=.true., but also
478      for a rotated grid (rotateGrid=.true.)
479    o pkg/exf: add capability to bypass interpolation for runoff
480      by setting yet another CPP-flag
481    o eesupp/src, B-grid exchange:
482      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
483    o autodiff
484      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
485      allows to switch to single-prec common blocks;
486      corresponding switch occurs in tamc.h, integer isbyte
487      TAF store directivs "byte" and "kind" seem equivalent;
488      Most tamc.h have been updated correspondingly.
489    
490    checkpoint61i
491    o autodiff:
492      fix autodiff_sore/_restore indices for obcs
493      (spotted by I. Hoteit, M. Mazloff)
494    o pkg/autodiff, pkg/ctrl:
495      Add flag to reduce all tapelev I/O to single-prec.
496      In data.ctrl set
497        doSinglePrecTapelev = .TRUE.
498    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
499      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
500    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
501      real fresh water flux (not yet)
502    o pkg/mdsio & rw:
503     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
504     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
505    o pkg/flt:
506     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
507       init_fixed & ini_varia.
508     - clean-up & simplify linear interpolation S/R:
509       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
510     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
511     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
512     - add vert. coordinate & horiz. indices to output files.
513     - change vertical position in initial condition, from index to depth [m].
514     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
515       (easier to get to a curvilinear grid) ; delX,delY no longer used.
516    o pkg/ggl90: a few modifications:
517     - fix bottom boundary condition, and interpolation of KappaE
518       near top and bottom
519     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
520     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
521     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
522    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
523      (maintain temporary backward compatibility, until next checkpoint)
524    
525    checkpoint61h
526    o pkg/diagnostics with "periodic averaging diagnostics":
527      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
528    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
529    o pkg/obcs: fix loop ranges for balancing code
530    o pkg/flt:
531     - improve criteria for finding which tile owns a float.
532     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
533    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
534      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
535      with ocean biogeo)
536    o pkg/flt:
537     - do some cleaning and fix the restart ;
538     - add output.txt in flt_example/results to get this pkg tested.
539    o genmake2: add an EXTENDED_SRC option and flag.
540       for now, cannot be turned on on command line (only through genmake_local)
541    o pkg/mdsio: read/write vector:
542     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
543     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
544       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
545     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
546      (drop to 4 digits matching for grad). But this test does not look very
547      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
548    
549    checkpoint61g
550    o pkg/flt:
551      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
552       + make OPTIONS file more standard.
553      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
554      - fix _BYTESWAPIO CPP-Flag
555      - standard reading of file-parameter "data.flt"
556      - fix argument list of S/R FLT_RESTART
557      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
558    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
559    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
560      a still unfixed compiler/optimization bug
561    
562    checkpoint61f
563    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
564      update results of global_ocean.cs32x15.icedyn test.
565    o move getcon.F from model/src to pkg/fizhi.
566    o pkg/exf: add parameter for extrapolation of temp up to the surface
567       and option to prevent negative evap (in bulk_largeyeager04 only).
568    o Prather Advection scheme: fix tracer conservation for divergent flow
569      (e.g., when using NonLin Free-Surface).
570    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
571    o gmredi (Visbeck-variable-K):
572     - add more parameters to Visbeck-variable-K.
573     - use a 5 points average for dSigmaR in Visbeck-K calculation
574       (more "homogenous": same stencil and same weights as in dSigmaH)
575     - update output of ideal_2D_oce experiment.
576    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
577      (#undef REAL4_IS_SLOW)
578     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
579       coordinate variable
580     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
581       (surface forcing fields), removes some of the functionality
582     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
583     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
584       probably not all: copy _RS surface flux fields to RL field before
585       calling DIAGNOSTICS_FILL
586     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
587       real*4 (CALL EXCH_*_RS) versions.
588     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
589       (generate new output).
590    
591    checkpoint61e
592    o gmredi (Visbeck-variable-K):
593      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
594      - change computation of Visbeck-K where Slope > Smax :        
595        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
596        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
597    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
598      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
599    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
600    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
601      does not become too large (to avoid precision problems in implicit-diffusion
602      solver); update ideal_2D_oce output.
603    o pkg ggl90:
604      - in ggl90_cal.F: compute only one set of visc/diff, used to
605        step forward TKE/T/S/momentum
606      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
607        have Prandlt =1)
608    o gmredi (fm07):
609      - add lower limit on Transition layer thickness + lower limit on 1/lambda
610      - allow to set few more params from data.gmredi
611    o pkg ggl90:
612          - add missing sqrt(2) factor in computation of mixing length
613            scale in ggl90_calc.F
614            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
615    
616    checkpoint61d
617    o adjoint modifs
618      - adapt to new field rhoInSitu
619      - allow to revert from StoreDynVars2D, StoreDynVars3D
620        to individual fields
621        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
622    o store 3-D (in-situ) density in commom block (DYNVARS.h)
623     - save 1 rho computation.
624     - no longer modify T & S inland when using down_slope pkg.
625    o gad_som : allow to switch to SOM advection for T & S without corresponding
626      pickup files (using new S/R: MDS_CHECK4FILE).
627    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
628      (for useSingleCpuIO to work in multi-threaded)
629    o pkg/shelfice:
630     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
631       with SHELFICEtopoFile in data.shelfice
632     - move code for reading ice shelf topography and modifying hFacC into separate
633       subroutines of the shelfice package
634     - separate initialisation of "fixed" and "variable" variables
635     - kTopC is not (yet) replaced by kSurfC, although this is possible
636    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
637    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
638      and rename:
639      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
640      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
641    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
642    
643    checkpoint61c
644    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
645      to add mass source/sink of fluid in the interior (3-D generalisation
646      of oceanic real-fresh water flux).
647    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
648    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
649    o new pkg: down_slope
650      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
651      - presently, modify T & S inland (dwnslp_calc_rho.F).
652        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
653      - implementation for ocean in P-coords not tested.
654      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
655    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
656      (to facilitate conversion of oceanic pkg to p-coordinate).
657    o change FIND_RHO to FIND_RHO_2D :
658      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
659    o new pkg: cheapaml
660    
661    checkpoint61b
662    o exch2:
663      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
664      - no longer depend on the order sequence (N,S,E,W).
665      - 3rd exchange no longer needed (tested with 24 tiles).
666      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
667      - exch_UV_A-grid readily available (but not yet tested).
668      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
669      (both are no longer needed) in exch_uv: no effect in forward run; but
670       get truncation error differences with adjoint exch.
671    o exch2:
672     - change index-bounds storage (moved from target to local tile,
673       more intuitive this way) ; rename/remove some variables.
674     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
675    
676    checkpoint61a
677    o exch2/matlab-topology-generator:
678      fix bug in index bounds for N-S internal exchange (hard to tell if this
679      had any effect on the solution).
680    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
681      is exceeded
682    o testreport: modify syntax of awk, so that it works also with
683      awk, and not only with nawk and gawk
684    
685    checkpoint61
686    o autodiff
687      Change default for TAF usage by removing argument '-nonew_arg'
688      This changes TAF subroutine argument list (ordering of active var.)
689      Omission of this flag leads to incompatibility w.r.t. TAMC
690      To restore TAMC-compatibility, need following modifs:
691      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
692      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
693      Tested TAF version is 1.9.22
694      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
695    
696    checkpoint60
697    --->>> This is the last checkpoint for which generating the adjoint
698    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
699    --->>> by default.
700    --->>> Future checkpoints will ommit this flag by default.
701    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
702    o pkg/grdchk: Add gradient check to etan0 perturbations.
703    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
704    o pkg/autodiff: more flexibility in zeroadj.
705      model/src: modifying do_oceanic_phys.F accordingly.
706    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
707    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
708      special setup of gmredi for which the adjoint is stable
709      enough for parameter optimization.
710    o bridging the gap between eddy stress and GM.
711      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
712          along with a change in CPP option (now ALLOW_EDDYPSI).
713      -> when using GM w/ GM_AdvForm:
714          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
715          is applied either in the tracer Eq. or in momentum Eq.
716          depending on data.gmredi (intro. GM_InMomAsStress).
717      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
718      The key modifications are in model/src/taueddy_external_forcing.F
719      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
720    
721    checkpoint59r
722    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
723      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
724      fix option to read coriolis(@ cell-corner) from files with CS-grid.
725    o pkg/mnc: add some attributes to standard 1D-coordinate variables
726    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
727      mass points, when using mnc for output
728      - add runtime parameter (missing_value, missing_value_int) to override
729        default (which is the value of getcon('UNDEF'))
730    o pkg/mnc: prepare mnc for the actual use of missing values with the
731      diagnostics package: small fix in mnc_cw_readwrite.template and more
732      initialisation of never used fields
733      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
734      versions
735    o pkg/thsice/thsice_ini_vars.F added default initial values so that
736      thermodynamics sea ice solver does not blow up when some initial fields
737      are missing.
738    o move from external_forcing_surf.F to ini_forcing.F
739      the p-coord. hack consisting in using pLoad to set phi0surf ;
740      update output of tutorial_global_oce_in_p (affected @ truncation level).
741    o Freshen up a bit hs94.1x64x5, notably:
742      remove rotationPeriod and tRef=5*0. (adjoint only), and add
743      exactConserv=.TRUE.
744    o pkg/generic_advdiff:
745      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
746      applies to files where Temperature & Salinity 2nd Order moments are used.
747    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
748      this uses a dynamically allocated internal state data structure
749      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
750      and requires a fortran 90 compiler
751    
752    checkpoint59q
753    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
754       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
755    o Refresh tutorial_global_oce_biogeo, notably:
756      - change bathymetry (put back seamounts in ACC, use hFacs)
757      - change EOS (POLY3 --> JMD95Z)
758      - use Bryan-Lewis vertical diffusivity
759      - use multidimensional advection
760      - remove old virtual virtual in dic pkg, now done through ptracer pkg
761      - change a couple of parameters in dic pkg
762    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
763    o pkg/obcs: change default to OBCSfixTopo = .true.,
764      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
765      - replace "debugMode" with "debugLevel .GE. debLevB"
766    o implementation of TAF directives for gchem,cfc,dic
767    o remove "exp5" (replaced by tutorial_deep_convection).
768    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
769      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
770      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
771      --> changes results in exp4, seaice_obcs
772    o tutorial_deep_convection :
773      update the set-up and increase resolution and domain size ; start
774      from pseudo initial conditions = output at t=120mn in order to see
775      something happening when running testreport.
776    o pkg/seaice: add os7mp as an advection scheme
777                  add check for advection schemes
778                  add a flag for restoring T and S underneath sea ice
779    o pkg/my82: add netcdf-support and diagnostics
780    o thsice pkg:
781      - Now hsMax limits snow height by turning it into ice following
782        flooding scheme (and now conserving energy)
783      - Slight rewriting of the formula in thsice_calc_thick.F
784      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
785      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
786    
787    checkpoint59p
788    o gchem / dic / cfc :
789      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
790      - add new parameter files: "data.dic" & "data.cfc" ;
791      - various re-arrangement in initialisation & header file ;
792      - fix tutorial_global_oce_biogeo for multi-threaded test.
793    o pkg/dic: test for "pickup_dic" file when restarting ;
794      if no pickup-file, can restart with a re-initialised pH (same as it did
795      before) providing pickupStrictlyMatch is set to False.
796    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
797      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
798    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
799      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
800    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
801     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
802       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
803    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
804       scheme to use for vorticty-term ;
805     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
806       (with default selectVortScheme, return to original discretisation)
807     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
808    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
809    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
810      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
811      also fix diagnostics VISCAHW & VISCA4W.
812    
813    checkpoint59o
814    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
815    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
816      move a few statemens out the main loop into separate loops
817    o pkg/shelfice:
818      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
819        (kg/m^2/s), does not break tests, because in verification/isomip,
820        rhoConstFresh=rhoConst (by accident)
821      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
822      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
823        new file model/src/seawater.F, so that they are available for all pkgs.
824      - convert potential temperature into in-situ temperature. This changes the
825        isomip tests => update tests
826    o add a flag writePickupAtEnd (default=true) to be able to suppress
827      writing a pickup at the last timestep
828    o tools/mpack-1.6 :
829      - disable automake (not working) and autoconf (not needed).
830      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
831        also cleaner with much less compilation warnings.
832    o pkg/profiles:
833      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
834      (for "less than 32 characters name" compiler requirement)
835    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
836      conditions that have a different sampling frequency than S/T/U/V obcs
837    o pkg/diagnostics (stats-diags):
838      - fix global Min/Max in case 1 processor get only empty tiles
839    o genmake2: replace (4 times)
840         make genmake_tc_1.o >> genmake_warnings 2>&1
841      with
842         COMM="$CC $CFLAGS -c genmake_tc_1.c"
843         echo $COMM >> genmake_warnings
844         $COMM >> genmake_warnings 2>&1
845      to make genmake2 always see the value of CC as specified in the optfile.
846    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
847      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
848      - modify verification advect_cs test to test SOM-advection on CS-grid.
849    o pkg/ctrl:
850      - Rewrite of ctrl_map_ini_ecco.F,
851        introducing a generic routine (ctrl_map_ini_gen.F).
852      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
853    
854    checkpoint59n
855    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
856      number in dedicate array "hdiag":
857      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
858        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
859      - many small changes (integer format) for large number of diagnostics
860      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
861        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
862    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
863      usingSphericalGrid, this allows to define the rotated grid coordinates
864      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
865      geographical coordinates according to the inverse of the rotation defined
866      by the Euler angles, so that Coriolis parameter and online-interpolation by
867      exf works with the geographical coordinates on XC/YC/XG/YG.
868      Naturally, this feature does not work with all packages, so some
869      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
870      profiles), because there the coordinates are assumed to be regular
871      spherical grid coordinates.
872    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
873      - introduce isopycnal diffusion coefficient control.
874    o tools/adjoint_options:
875      - additional control vector components.
876    o pkg/mnc: have mnc create marginally meaning full coordinate variables
877      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
878    o pkg/mypackage:
879      - add example of read/write pickup for state-var ;
880      - add entry points to the main code for state-vars diags & write-pickup.
881    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
882      transitions for useExfYearlyFields
883      - add new subroutine that determines the file to read from for
884        use*YearlyFields = .TRUE. and .FALSE.
885      - add a verification experiment to global_with_exf that tests
886        useExfYearlyFields with USE_EXF_INTERPOLATION defined
887    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
888      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
889      subroutines (which could be generated from a template, because they are
890      almost identical), for now they are included in obcs_prescribe_read.F for
891      simplicity
892    o pkg/exf:
893      - add a little more diagnostic to exf_interp_read (in analogy to
894        mds_read_field, can be turned off with debugLevel < debugLevA=1)
895      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
896        ugly but fast by unrolling short inner loops, inserting a unroll=8
897        directive in routine lagran, and splitting a loop and making do while the
898        outermost loop (the latter requires the intoduction of index arrays)
899    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
900    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
901      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
902    o verification/seaice_obcs: updated for restart test and latest options
903    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
904      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
905      for now this is only available for the C-grid code and also within
906      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
907    
908    checkpoint59m
909    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
910      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
911    o gad_som : fix flux output (& diagnostics) to have same units as other  
912      advection scheme fluxes (was previously multiplied by deltaT).  
913    o added verification/seaice_obcs both to test seaice open boundaries
914      and to provide an example matlab scrpt for generating them
915    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
916    o pkg/salt_plume: clean up salt_plume_frac.F to
917      remove redundancy in PlumeMethod 1 and 4
918    o pkg/kpp: added saltplume diagnostics
919    o pkg/obcs and pkg/seaice:
920      - do not set uice and vice to zero when OB*icefile are unspecified
921      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
922      - moved seaice tracer obcs after call to seaice_growth
923    o pkg/salt_plume: added various options for salt plume depth
924      criterion and for vertical distribution of the salt
925    
926    checkpoint59l
927    o pkg/ptracers: new version of ptracers pickup:
928      read meta file and write only fields which are needed to restart.
929      ( same logic as main pickup file ; also using pickupStrictlyMatch )
930    o pkg/seaice:
931      - add timescale for melting due to warm mixed layer as a means of
932        setting SEAICE_availHeatFrac more conveniently
933      - add a CPP-flag/runtime parameter check for flooding algorithm
934      - reformulated availHeat in seaice_growth.F to be independent of AREA
935    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
936      unit changes
937    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
938    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
939      SX vector computer.
940    o pkg/seaice:
941      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
942        seaice forcing fields can now be read only through pkg/exf
943      - removed some unused halos
944    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
945    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
946      or U/VICE from U/VWIND before computing U/VSTRESS
947    
948    checkpoint59k
949    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
950      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
951    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
952      all experiments pass when compile with un-initialised var. checking option.
953    o added pkg/salt_plume
954    o script to test restart (for now, in MITgcm_contrib/jmc_script)
955    o pkg/seaice: new read/write pickup version.
956      read meta file and write only fields which are needed to restart.
957      ( same logic as main pickup file ; also using pickupStrictlyMatch )
958    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
959    o lab_sea.hb87: modify the domain & update output.hb87.txt :
960      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
961      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
962      process. Fixed here by closing the domain at the Northern boundary.
963    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
964    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
965      a set of consecutive levels in/from a 3-D array.
966    o pkg/ptracers:
967      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
968      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
969    
970    checkpoint59j
971    o in pkgs: dic, obcs, offline, rbcs:
972      standard way to compute coeff. for time interpolation between 2 time reccords
973      which retains full precision (& make results less dependent on compiler).
974      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
975    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
976      packages instead of reading ice cover and wind speed separately
977    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
978     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
979      to allow to compile customized code before the update)
980    o cleaning-up:
981      - fix CPP instruction syntax in pkg/obcs
982      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
983        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
984      - fix some threads issue in IO parts.
985  o pkg/dic:  o pkg/dic:
986    - add tons of "_d 0" (--> much better testreports !)    - add tons of "_d 0" (--> much better testreports !)
