4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    checkpoint61w
8    o adjoint:
9      * update and finish work on adjoint of dic package (G. Forget)
10      * start adjoint of offline package
11      * bug fix for cube-sphere TLM code (active_file_g.F)
12    o tutorial_global_oce_optim:
13      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
14      and add SIZE.h_mpi for MPI testing
15    o pkg autodiff
16     - fix bug in autodiff_restore
17     - make genmake2 remove comments and empty lines from ad_input_code.f in
18       order to reduce file size (new script file remove_comments_sed)
19    o allows to specify vertical profile of vertical viscosity (viscArNr)
20    o pkg autodiff
21      autodiff_ini_model_io: comment out writing of grid information to netcdf
22      files, because at this time the grid fields are a bunch of zeros
23      (this is analogous to ini_mnc_vars.F)
24    o pkg seaice/autodiff:
25     left-over from removing the 3-time-level fields:
26     - small rearrangement of common blocks (SEAICE.h)
27     - fix field declaration in order to get meaningful output in
28       adseaice.*.nc (adcommon.h)
29    o pkg obcs:
30     - go through NH code only if nonHydrostatic=T
31     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
32     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
33       => Update output of experiment seaice_obcs
34     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
35     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
36     - fix restart for useOBCSprescribe + useEXF
37    o pkg ctrl
38     - make obcs as control parameter work also with useSingleCPUio
39     - replace a few sny and snx by Ny and Nx to be consistent with
40       ctrl_set_globfld_x/yz.F
41    o pkg seaice
42     - re-introduce global field frWtrAtm for the case of
43       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
44     - catch the case of an empty filename in seaice_cost_init_fixed.F
45    o pkg ecco:
46     - small bug fixes in the_main_loop
47      . fix order of monitor arguments
48      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
49      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
50        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
51     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
52       imbalance diagnostics for wmean_h/sflux = 0
53     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
54     - catch the case of empty filenames in ecco_cost_init_fixed.F
55       and ecco_readparms.F
56     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
57       to make this statement meaningfull in ecco_cost_weights.F
58    o pkg zonal_filt:
59      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
60      - when using rStar, filter uVel*hFacW instead of uVel
61       (tested without topography: fix a Pb of growing instability with NLFS)
62    o pkg/aim/thsice:
63     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
64      (works as SST restoring)
65    o pkg/thsice:
66     -add specific parameter for salt restoring in slab mixed-layer
67       (by default equal to the temperature restoring)
68    
69    checkpoint61v
70    o pkg/kpp:
71     -add double diffusive contributions as a hack, turned off by default
72      for now, and the code can be excluded with a CPP-flag
73      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
74     -add a verification experiments to "vermix" to test this code
75    o pkg/mom_common:
76      Move computation of length scales to mom_init_fixed.F (avoid recomputation
77      at each time-steps*levels).
78    o pkg/layers:
79      Created a new package for computing volume fluxes in temperature or
80      [not yet implemented] density layers, e.g. for calculating residual
81      overturning circulations.
82    o pkg/diagnostics:
83      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
84    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
85    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
86      To avoid mixing type (RS/RL) of input/output array argument,
87      replace single mixed-type array with a pair from each type (RS/RL).
88    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
89      is now implemented for all pkgs (previously only done for the main pickup)
90    
91    checkpoint61u
92    o pkg/obcs:
93      - change OB?eta from _RS to _RL and put them into a separate commen block
94      - add code to read OB?eta from a file via obcs_prescribe_read: the code
95        compiles and does not destroy any other experiments, the data is read
96        properly, but the code is not tested in actual applications
97    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
98      create a meaningful unit attribute for the time coordinate variable
99    o pkg/ebm: add plenty of missing "_d 0" ;
100       update results of experiment global_ocean_ebm (fwd + adjoint tests)
101      Notes: several pieces of code only works for (very) specific set up
102       (domain size, lat range, etc ...); should be documented & stop if one
103       of those assumptions is not meet.
104    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
105       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
106          and offline_exf_seaice (seaicetd + adjoint).
107    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
108       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
109        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
110    o few changes to pass when compiling with strick checking of arguments
111       across S/R (allow to find few bugs in S/R calls).
112    o pkg/seaice:
113     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
114       2d-fields, for slightly better performance
115    
116    checkpoint61t
117    o pkg/seaice:
118     - remove unused variables in seaice_evp
119     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
120    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
121       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
122       each processor opens a different file (a fix from Matt).
123    o cg2d:
124       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
125       this reduces number of EXCH calls by 2 when using exch2.
126       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
127       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
128    o pkg/thsice:
129       add code for Near Infra-Red albedo (from Jeff)
130       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
131    o ini_model_io:
132       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
133       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
134       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
135    
136    checkpoint61s
137    o pkg/exch2 (exch2_rxN_cube*):
138       remove last BARRIER (no need to synchronise after getting data from shared
139       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
140    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
141      and generate new output (for the 2 tests) using default rotationPeriod.
142    o pkg/exch2:
143      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
144        (was already the case with AUTODIFF_EXCH2 defined)
145      - add bj in exch2 arrays and S/R.
146      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
147        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
148    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
149      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
150        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
151      - verification experiment natl_box.longstep
152    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
153      allow different versions of ifort (8 or 9) and different versions
154       of mpi (mpich or mpich2) to be used with the same optfile.
155      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
156       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
157    o pkg/seaice:
158      fix previous modif (3-level field removed) for old-pickup reading
159    
160    checkpoint61r
161    o pkg/seaice:
162     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
163      1. introduce fields for time step (N-1)
164      2. do not use levels 2 and 3 anymore (but keep them)
165      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
166         includes changes to pkg/thsice/thsice_get_velocity.F,
167         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
168         pkg/obcs/obcs_apply_uvice.F.
169     - completely remove code for leap-frog time stepping for second order
170       advection
171     - adjusted adjoint accordingly;
172       gradient checks have improved by an order of magnitude!
173    
174    checkpoint61q
175    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
176     - the boundary conditions along open boundaries are unclear, because the
177       associated masks are set to zero and are thus treated as closed when
178       applying the slip-boundary conditions.
179     - move initialisation of grid variables from seaice_init_varia to _fixed
180    o adding doc/diags_changes.txt
181    o model/src:
182      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
183       to avoid "_diags" naming if no relation to pkg/diagnostics.
184      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
185       file and only call PLOT_FIELD_XYZ if debugMode=T.
186      remove few PLOT_FIELD_XY calls outside initialisation.
187      remove few unnecessary BARRIER.
188    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
189      of salt_plume package in Southern Ocean
190    o pkg/thsice:
191     - fix hOceMxL in overlap (needed for sea-ice advection);
192       update output of experiment global_ocean.cs32x15.icedyn.
193    o pkg/seaice:
194     - make the (placeholder-)tracer IceAge a little more meaningful
195      by avoiding ridging of age due to convergent ice flow
196     - add diagnostics for surface temperature, atmospheric and oceanic
197       heat flux, and atmospheric and oceanic ice growth
198    
199    checkpoint61p
200    o eesupp (global_max & global_sum):
201     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
202     - remove starting & endding barrier (no longer needed)
203    o pkg/mdsio, writelocal:
204       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
205       (remove the STOP): uses shared buffer IO to store data from all threads
206       and then let master-thread write nThreads tiles.
207    o pkg/mdsio (read/write field):
208     - tiled IO done in 1 piece (all levels at a time);
209     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
210     - multi-threaded: allow to read/write local (non-shared) array
211       (was already working with singleCpuIO ; now works also without);
212       => no longer needs barrier call after reading a file (added inside
213       mds_read/write field).
214     - move barrier calls outside gather/scatter_2d to mds_read/write_field
215    o pkg/obcs/exf
216      - exf_getffieldrec.F: add a few ". _d 0" and
217                            add code to catch the case fldperiod = 0.  
218      - obcs_precribe_read.F: change if statements so that they match
219                              the variable type (_RL)
220      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
221        exf_iprec) as part of namelist EXF_NML_01
222    o pkg/mdsio:
223      - read/write tiled (local) files: read/write 1-level tile chunk at a time
224        (instead of segment of length sNx); expected to speed up tiled IO.
225    o pkg/exch2:
226      - take buffer copy from/to array out of S/R exch2_send/recv into new
227        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
228        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
229      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
230      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
231        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
232        including Topology header file (and common blocks).
233      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
234        remove 2nd exch call in exch2_s3d_rx (no longer needed).
235      - document S/R arg. list (+ update some comments)
236    o pkg/seaice:
237      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
238        temperature and humidity over sea ice based on climatological values.
239      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
240        of LSR (this change is expected to change the results slightly because now
241        it uses slightly difference moduli from the second last LSR solution, but
242        that is more consistent with the stress computations; this part of the code
243        is not tested in the verification experiments)
244      - fix diagnostics for flux of ice in case of B-grid
245      - turn strain rates eij and press into global fields within global
246        common block in SEAICE.h for more straighforward diagnostics
247      - fix diagnostics for principal stress components, press, zeta, eta
248        to give something meaning full
249    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
250      new output (all 4 tests) using default rotationPeriod.
251    o pkg KPP:
252      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
253      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
254        and normal grid from 1 to Nr)
255    o Fix computations of L4rdt in mom_calc_visc.F
256    o eesupp:
257      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
258      should be called before a "stop" if we know that all process are going
259      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
260    
261    checkpoint61o
262    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
263    o model/src/ini_curvilinear_grid.F:
264       compute angleSin/CosC when they are not read from a file
265    o pkg/seaice:
266       add pseudo time stepping for LSOR
267    o pkg/exch2:
268       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
269    o pkg/seaice:
270       Adding separate sea ice albedo, drag coefficients, and HO in Southern
271       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
272    o SingleCpuIO:
273       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
274    o pkg/seaice:
275       put exchanged variable in (local) common block for MPI+Multi-Threads
276       to work (necessary with exch1, and for now with exch2 too).
277    o verification: to get more experiments tested with mpi, mth and mpi+mth,
278      change tiling of:
279       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
280       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
281      update output of exp:
282       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
283       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
284      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
285                       (note: output.txt generated on faulks using only 1 tile)
286    o eesupp & mdsio (SingleCpuIO):
287     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
288       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
289       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
290     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
291     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
292       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
293    o pkg/exch2:
294     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
295       read parameter file "data.exch2" if it exists; otherwise try default regular
296       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
297     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
298       with new code (not to be used, just as a backup solution).
299     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
300       in utils/exch2/input.
301    
302    checkpoint61n
303    o eesupp & mdsio (SingleCpuIO):
304      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
305        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
306        receive real*4 array (instead of real*8) to read/write 32.bit files.
307        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
308         and remove new mapping S/R)
309    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
310      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
311        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
312        when using exch2. Add S/R to map global io-buffer to global model array.
313      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
314    
315    checkpoint61m
316    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
317      and add 3 other S/R for other types (R4,R8,RS).
318      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
319    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
320     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
321     - reduce number of macro definitions (keep only those which are used);
322       can always call directly the corrresponding S/R if needed.
323     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
324       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
325     Fixed wrong type of arg in:
326       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
327       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
328     To fix: global_sum of var in common block is wrong (multi-threaded) in:
329       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
330     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
331    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
332      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
333    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
334    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
335      edges are closed (zero depth); might happen with "blank tiles";
336      for now, disabled if using OBCS.
337    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
338      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
339    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
340      to reduce length of 1.D array print in STDOUT.
341    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
342      + use 48 tiles (16x8): this will allow to test "blank tiles".
343    o start to test MPI + multi-threaded (change testreport to skip tests
344      where number of tiles do not match).
345    o genmake2: add option "-omp" to turn on Open-MP ;
346      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
347    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
348      and keep the original tile numbering. Note: compatible with old
349      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
350    
351    checkpoint61l
352    o Overlaps had been forgotten in calculating ijk keys : fixed
353    o fix cyrus makedepend for gcc 4.4
354    o experiment fizhi-cs-aqualev20:
355      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
356      and generate new output. Note: new output is much closer to the old
357      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
358      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
359    o pkg/fizhi:
360     - change to avoid indices going deliberately over array-bounds
361     - remove unnecessary MPI stuff
362     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
363     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
364       does not go over array-bounds and therefore returns reliable output.
365     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
366       this S/R has 4 output arguments, which are used inside "get_alarm";
367       when it is called with the same variable "ndum" in place of several
368       output arguments, this produces weird side effect inside "get_alarm"
369      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
370       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
371       address) and produces error.
372    o tools/gemake2: (March 27-29 2009)
373      with option "-mpi": link *_mpi files from "MODS" dir (this is what
374      testreport does).
375    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
376    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
377       update lab_sea.lsr & lab_sea.salt_plume results
378    o pkg/seaice:
379      Major overhaul of the LSOR solver: change discretization from original
380      finite differences to finite volume. The old routine is still in the
381      file seaice_lsr.F and can be turned on with the CPP-flag
382      SEAICE_OLD_AND_BAD_DISCRETIZATION
383      Along with this change, the discretization of the strain rates is changed.
384      The same flag turns on the old discretization in seaice_calc_strainrates.F
385      All verification experiments with seaice are affected (except for
386      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
387      results by setting the above flag.
388      Further changes involve changes in defaults:
389      - ALLOW_FLOODING is defined and turned on by default
390      - SEAICEadvSnow = .true. is now the default
391      - SEAICEadvSalt = .true. is now the default
392      - SEAICEadvAge  = .true. is now the default
393      - SEAICE_clipVelocities  = .false. is now the default
394                                         (as per J. Zhang's recommendation)
395      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
396        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
397      - seaice_growth: replace computation of UG by a simple copy from wspeed
398    
399    checkpoint61k
400    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
401      seaice_lsr: fixed a few metric terms,
402                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
403                  add more debugging diagnostics
404      seaice_evp: removed superfluous many metric terms of FV discretization
405                  of stress divergence
406                  affects lab_sea, lab_sea.hb87
407      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
408                  of stress divergence for non-evp solver
409                  (this part is not tested anywhere)
410      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
411                  they were effectively only half slip
412                  affects lab_sea.hb87
413      updated all relevant verification experiments (except lab_sea//output_adm.txt
414        which was left over, but fails at level 7 & 6)
415    
416    checkpoint61j
417    o pkg/seaice: turn a few hard wired parameters into run time parameters
418    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
419      time in seconds as promised by the usints in seaice_monitor and exf_monitor
420    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
421      that are not cubed-sphere grids
422    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
423    o pkg/ctrl:
424      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
425    o non-hydrostatic (calc_gw.F):
426      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
427      update output of exp. global_ocean.cs32x15.viscA4
428    o remove backward compatibility for thetaMin,phiMin
429      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
430    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
431      interpolated wind field not only for curvilineargrid=.true., but also
432      for a rotated grid (rotateGrid=.true.)
433    o pkg/exf: add capability to bypass interpolation for runoff
434      by setting yet another CPP-flag
435    o eesupp/src, B-grid exchange:
436      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
437    o autodiff
438      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
439      allows to switch to single-prec common blocks;
440      corresponding switch occurs in tamc.h, integer isbyte
441      TAF store directivs "byte" and "kind" seem equivalent;
442      Most tamc.h have been updated correspondingly.
443    
444    checkpoint61i
445    o autodiff:
446      fix autodiff_sore/_restore indices for obcs
447      (spotted by I. Hoteit, M. Mazloff)
448    o pkg/autodiff, pkg/ctrl:
449      Add flag to reduce all tapelev I/O to single-prec.
450      In data.ctrl set
451        doSinglePrecTapelev = .TRUE.
452    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
453      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
454    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
455      real fresh water flux (not yet)
456    o pkg/mdsio & rw:
457     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
458     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
459    o pkg/flt:
460     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
461       init_fixed & ini_varia.
462     - clean-up & simplify linear interpolation S/R:
463       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
464     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
465     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
466     - add vert. coordinate & horiz. indices to output files.
467     - change vertical position in initial condition, from index to depth [m].
468     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
469       (easier to get to a curvilinear grid) ; delX,delY no longer used.
470    o pkg/ggl90: a few modifications:
471     - fix bottom boundary condition, and interpolation of KappaE
472       near top and bottom
473     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
474     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
475     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
476    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
477      (maintain temporary backward compatibility, until next checkpoint)
478    
479    checkpoint61h
480    o pkg/diagnostics with "periodic averaging diagnostics":
481      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
482    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
483    o pkg/obcs: fix loop ranges for balancing code

485     - improve criteria for finding which tile owns a float.
486     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
487    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
488      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
489      with ocean biogeo)
490    o pkg/flt:
491     - do some cleaning and fix the restart ;
492     - add output.txt in flt_example/results to get this pkg tested.
493    o genmake2: add an EXTENDED_SRC option and flag.
494       for now, cannot be turned on on command line (only through genmake_local)
495    o pkg/mdsio: read/write vector:
496     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
497     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
498       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
499     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
500      (drop to 4 digits matching for grad). But this test does not look very
501      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
502    
503    checkpoint61g
504    o pkg/flt:
505      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
506       + make OPTIONS file more standard.
507      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
508      - fix _BYTESWAPIO CPP-Flag
509      - standard reading of file-parameter "data.flt"
510      - fix argument list of S/R FLT_RESTART
511      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
512    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
513    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
514      a still unfixed compiler/optimization bug
515    
516    checkpoint61f
517    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
518      update results of global_ocean.cs32x15.icedyn test.
519    o move getcon.F from model/src to pkg/fizhi.
520    o pkg/exf: add parameter for extrapolation of temp up to the surface
521       and option to prevent negative evap (in bulk_largeyeager04 only).
522    o Prather Advection scheme: fix tracer conservation for divergent flow
523      (e.g., when using NonLin Free-Surface).
524    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
525    o gmredi (Visbeck-variable-K):
526     - add more parameters to Visbeck-variable-K.
527     - use a 5 points average for dSigmaR in Visbeck-K calculation
528       (more "homogenous": same stencil and same weights as in dSigmaH)
529     - update output of ideal_2D_oce experiment.
530    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
531      (#undef REAL4_IS_SLOW)
532     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
533       coordinate variable
534     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
535       (surface forcing fields), removes some of the functionality
536     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
537     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
538       probably not all: copy _RS surface flux fields to RL field before
539       calling DIAGNOSTICS_FILL
540     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
541       real*4 (CALL EXCH_*_RS) versions.
542     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
543       (generate new output).
544    
545    checkpoint61e
546    o gmredi (Visbeck-variable-K):
547      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
548      - change computation of Visbeck-K where Slope > Smax :        
549        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
550        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
551    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
552      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
553    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
554    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
555      does not become too large (to avoid precision problems in implicit-diffusion
556      solver); update ideal_2D_oce output.
557    o pkg ggl90:
558      - in ggl90_cal.F: compute only one set of visc/diff, used to
559        step forward TKE/T/S/momentum
560      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
561        have Prandlt =1)
562    o gmredi (fm07):
563      - add lower limit on Transition layer thickness + lower limit on 1/lambda
564      - allow to set few more params from data.gmredi
565    o pkg ggl90:
566          - add missing sqrt(2) factor in computation of mixing length
567            scale in ggl90_calc.F
568            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
569    
570    checkpoint61d
571    o adjoint modifs
572      - adapt to new field rhoInSitu
573      - allow to revert from StoreDynVars2D, StoreDynVars3D
574        to individual fields
575        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
576    o store 3-D (in-situ) density in commom block (DYNVARS.h)
577     - save 1 rho computation.
578     - no longer modify T & S inland when using down_slope pkg.
579    o gad_som : allow to switch to SOM advection for T & S without corresponding
580      pickup files (using new S/R: MDS_CHECK4FILE).
581    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
582      (for useSingleCpuIO to work in multi-threaded)
583    o pkg/shelfice:
584     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
585       with SHELFICEtopoFile in data.shelfice
586     - move code for reading ice shelf topography and modifying hFacC into separate
587       subroutines of the shelfice package
588     - separate initialisation of "fixed" and "variable" variables
589     - kTopC is not (yet) replaced by kSurfC, although this is possible
590    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
591    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
592      and rename:
593      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
594      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
595    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
596    
597    checkpoint61c
598    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
599      to add mass source/sink of fluid in the interior (3-D generalisation
600      of oceanic real-fresh water flux).
601    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
602    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
603    o new pkg: down_slope
604      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
605      - presently, modify T & S inland (dwnslp_calc_rho.F).
606        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
607      - implementation for ocean in P-coords not tested.
608      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
609    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
610      (to facilitate conversion of oceanic pkg to p-coordinate).
611    o change FIND_RHO to FIND_RHO_2D :
612      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
613    o new pkg: cheapaml
614    
615    checkpoint61b
616    o exch2:
617      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
618      - no longer depend on the order sequence (N,S,E,W).
619      - 3rd exchange no longer needed (tested with 24 tiles).
620      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
621      - exch_UV_A-grid readily available (but not yet tested).
622      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
623      (both are no longer needed) in exch_uv: no effect in forward run; but
624       get truncation error differences with adjoint exch.
625    o exch2:
626     - change index-bounds storage (moved from target to local tile,
627       more intuitive this way) ; rename/remove some variables.
628     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
629    
630    checkpoint61a
631  o exch2/matlab-topology-generator:  o exch2/matlab-topology-generator:
