4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o pkg/layers:
7      Created a new package for computing volume fluxes in temperature or
8      [not yet implemented] density layers, e.g. for calculating residual
9      overturning circulations.
10    o pkg/diagnostics:
11      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
12    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
13    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
14      To avoid mixing type (RS/RL) of input/output array argument,
15      replace single mixed-type array with a pair from each type (RS/RL).
16    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
17      is now implemented for all pkgs (previously only done for the main pickup)
18    
19    checkpoint61u
20    o pkg/obcs:
21      - change OB?eta from _RS to _RL and put them into a separate commen block
22      - add code to read OB?eta from a file via obcs_prescribe_read: the code
23        compiles and does not destroy any other experiments, the data is read
24        properly, but the code is not tested in actual applications
25    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
26      create a meaningful unit attribute for the time coordinate variable
27    o pkg/ebm: add plenty of missing "_d 0" ;
28       update results of experiment global_ocean_ebm (fwd + adjoint tests)
29      Notes: several pieces of code only works for (very) specific set up
30       (domain size, lat range, etc ...); should be documented & stop if one
31       of those assumptions is not meet.
32    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
33       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
34          and offline_exf_seaice (seaicetd + adjoint).
35    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
36       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
37        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
38    o few changes to pass when compiling with strick checking of arguments
39       across S/R (allow to find few bugs in S/R calls).
40    o pkg/seaice:
41     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
42       2d-fields, for slightly better performance
43    
44    checkpoint61t
45    o pkg/seaice:
46     - remove unused variables in seaice_evp
47     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
48    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
49       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
50       each processor opens a different file (a fix from Matt).
51    o cg2d:
52       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
53       this reduces number of EXCH calls by 2 when using exch2.
54       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
55       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
56    o pkg/thsice:
57       add code for Near Infra-Red albedo (from Jeff)
58       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
59    o ini_model_io:
60       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
61       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
62       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
63    
64    checkpoint61s
65    o pkg/exch2 (exch2_rxN_cube*):
66       remove last BARRIER (no need to synchronise after getting data from shared
67       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
68    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
69      and generate new output (for the 2 tests) using default rotationPeriod.
70    o pkg/exch2:
71      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
72        (was already the case with AUTODIFF_EXCH2 defined)
73      - add bj in exch2 arrays and S/R.
74      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
75        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
76    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
77      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
78        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
79      - verification experiment natl_box.longstep
80    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
81      allow different versions of ifort (8 or 9) and different versions
82       of mpi (mpich or mpich2) to be used with the same optfile.
83      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
84       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
85    o pkg/seaice:
86      fix previous modif (3-level field removed) for old-pickup reading
87    
88    checkpoint61r
89    o pkg/seaice:
90     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
91      1. introduce fields for time step (N-1)
92      2. do not use levels 2 and 3 anymore (but keep them)
93      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
94         includes changes to pkg/thsice/thsice_get_velocity.F,
95         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
96         pkg/obcs/obcs_apply_uvice.F.
97     - completely remove code for leap-frog time stepping for second order
98       advection
99     - adjusted adjoint accordingly;
100       gradient checks have improved by an order of magnitude!
101    
102    checkpoint61q
103    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
104     - the boundary conditions along open boundaries are unclear, because the
105       associated masks are set to zero and are thus treated as closed when
106       applying the slip-boundary conditions.
107     - move initialisation of grid variables from seaice_init_varia to _fixed
108    o adding doc/diags_changes.txt
109    o model/src:
110      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
111       to avoid "_diags" naming if no relation to pkg/diagnostics.
112      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
113       file and only call PLOT_FIELD_XYZ if debugMode=T.
114      remove few PLOT_FIELD_XY calls outside initialisation.
115      remove few unnecessary BARRIER.
116    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
117      of salt_plume package in Southern Ocean
118    o pkg/thsice:
119     - fix hOceMxL in overlap (needed for sea-ice advection);
120       update output of experiment global_ocean.cs32x15.icedyn.
121    o pkg/seaice:
122     - make the (placeholder-)tracer IceAge a little more meaningful
123      by avoiding ridging of age due to convergent ice flow
124     - add diagnostics for surface temperature, atmospheric and oceanic
125       heat flux, and atmospheric and oceanic ice growth
126    
127    checkpoint61p
128    o eesupp (global_max & global_sum):
129     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
130     - remove starting & endding barrier (no longer needed)
131    o pkg/mdsio, writelocal:
132       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
133       (remove the STOP): uses shared buffer IO to store data from all threads
134       and then let master-thread write nThreads tiles.
135    o pkg/mdsio (read/write field):
136     - tiled IO done in 1 piece (all levels at a time);
137     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
138     - multi-threaded: allow to read/write local (non-shared) array
139       (was already working with singleCpuIO ; now works also without);
140       => no longer needs barrier call after reading a file (added inside
141       mds_read/write field).
142     - move barrier calls outside gather/scatter_2d to mds_read/write_field
143    o pkg/obcs/exf
144      - exf_getffieldrec.F: add a few ". _d 0" and
145                            add code to catch the case fldperiod = 0.  
146      - obcs_precribe_read.F: change if statements so that they match
147                              the variable type (_RL)
148      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
149        exf_iprec) as part of namelist EXF_NML_01
150    o pkg/mdsio:
151      - read/write tiled (local) files: read/write 1-level tile chunk at a time
152        (instead of segment of length sNx); expected to speed up tiled IO.
153    o pkg/exch2:
154      - take buffer copy from/to array out of S/R exch2_send/recv into new
155        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
156        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
157      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
158      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
159        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
160        including Topology header file (and common blocks).
161      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
162        remove 2nd exch call in exch2_s3d_rx (no longer needed).
163      - document S/R arg. list (+ update some comments)
164    o pkg/seaice:
165      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
166        temperature and humidity over sea ice based on climatological values.
167      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
168        of LSR (this change is expected to change the results slightly because now
169        it uses slightly difference moduli from the second last LSR solution, but
170        that is more consistent with the stress computations; this part of the code
171        is not tested in the verification experiments)
172      - fix diagnostics for flux of ice in case of B-grid
173      - turn strain rates eij and press into global fields within global
174        common block in SEAICE.h for more straighforward diagnostics
175      - fix diagnostics for principal stress components, press, zeta, eta
176        to give something meaning full
177    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
178      new output (all 4 tests) using default rotationPeriod.
179    o pkg KPP:
180      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
181      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
182        and normal grid from 1 to Nr)
183    o Fix computations of L4rdt in mom_calc_visc.F
184    o eesupp:
185      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
186      should be called before a "stop" if we know that all process are going
187      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
188    
189    checkpoint61o
190    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
191    o model/src/ini_curvilinear_grid.F:
192       compute angleSin/CosC when they are not read from a file
193    o pkg/seaice:
194       add pseudo time stepping for LSOR
195    o pkg/exch2:
196       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
197    o pkg/seaice:
198       Adding separate sea ice albedo, drag coefficients, and HO in Southern
199       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
200    o SingleCpuIO:
201       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
202    o pkg/seaice:
203       put exchanged variable in (local) common block for MPI+Multi-Threads
204       to work (necessary with exch1, and for now with exch2 too).
205    o verification: to get more experiments tested with mpi, mth and mpi+mth,
206      change tiling of:
207       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
208       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
209      update output of exp:
210       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
211       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
212      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
213                       (note: output.txt generated on faulks using only 1 tile)
214    o eesupp & mdsio (SingleCpuIO):
215     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
216       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
217       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
218     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
219     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
220       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
221    o pkg/exch2:
222     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
223       read parameter file "data.exch2" if it exists; otherwise try default regular
224       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
225     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
226       with new code (not to be used, just as a backup solution).
227     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
228       in utils/exch2/input.
229    
230    checkpoint61n
231    o eesupp & mdsio (SingleCpuIO):
232      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
233        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
234        receive real*4 array (instead of real*8) to read/write 32.bit files.
235        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
236         and remove new mapping S/R)
237    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
238      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
239        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
240        when using exch2. Add S/R to map global io-buffer to global model array.
241      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
242    
243    checkpoint61m
244    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
245      and add 3 other S/R for other types (R4,R8,RS).
246      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
247    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
248     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
249     - reduce number of macro definitions (keep only those which are used);
250       can always call directly the corrresponding S/R if needed.
251     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
252       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
253     Fixed wrong type of arg in:
254       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
255       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
256     To fix: global_sum of var in common block is wrong (multi-threaded) in:
257       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
258     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
259    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
260      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
261    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
262    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
263      edges are closed (zero depth); might happen with "blank tiles";
264      for now, disabled if using OBCS.
265    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
266      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
267    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
268      to reduce length of 1.D array print in STDOUT.
269    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
270      + use 48 tiles (16x8): this will allow to test "blank tiles".
271    o start to test MPI + multi-threaded (change testreport to skip tests
272      where number of tiles do not match).
273    o genmake2: add option "-omp" to turn on Open-MP ;
274      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
275    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
276      and keep the original tile numbering. Note: compatible with old
277      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
278    
279    checkpoint61l
280    o Overlaps had been forgotten in calculating ijk keys : fixed
281    o fix cyrus makedepend for gcc 4.4
282    o experiment fizhi-cs-aqualev20:
283      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
284      and generate new output. Note: new output is much closer to the old
285      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
286      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
287    o pkg/fizhi:
288     - change to avoid indices going deliberately over array-bounds
289     - remove unnecessary MPI stuff
290     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
291     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
292       does not go over array-bounds and therefore returns reliable output.
293     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
294       this S/R has 4 output arguments, which are used inside "get_alarm";
295       when it is called with the same variable "ndum" in place of several
296       output arguments, this produces weird side effect inside "get_alarm"
297      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
298       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
299       address) and produces error.
300    o tools/gemake2: (March 27-29 2009)
301      with option "-mpi": link *_mpi files from "MODS" dir (this is what
302      testreport does).
303    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
304    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
305       update lab_sea.lsr & lab_sea.salt_plume results
306    o pkg/seaice:
307      Major overhaul of the LSOR solver: change discretization from original
308      finite differences to finite volume. The old routine is still in the
309      file seaice_lsr.F and can be turned on with the CPP-flag
310      SEAICE_OLD_AND_BAD_DISCRETIZATION
311      Along with this change, the discretization of the strain rates is changed.
312      The same flag turns on the old discretization in seaice_calc_strainrates.F
313      All verification experiments with seaice are affected (except for
314      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
315      results by setting the above flag.
316      Further changes involve changes in defaults:
317      - ALLOW_FLOODING is defined and turned on by default
318      - SEAICEadvSnow = .true. is now the default
319      - SEAICEadvSalt = .true. is now the default
320      - SEAICEadvAge  = .true. is now the default
321      - SEAICE_clipVelocities  = .false. is now the default
322                                         (as per J. Zhang's recommendation)
323      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
324        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
325      - seaice_growth: replace computation of UG by a simple copy from wspeed
326    
327    checkpoint61k
328    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
329      seaice_lsr: fixed a few metric terms,
330                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
331                  add more debugging diagnostics
332      seaice_evp: removed superfluous many metric terms of FV discretization
333                  of stress divergence
334                  affects lab_sea, lab_sea.hb87
335      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
336                  of stress divergence for non-evp solver
337                  (this part is not tested anywhere)
338      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
339                  they were effectively only half slip
340                  affects lab_sea.hb87
341      updated all relevant verification experiments (except lab_sea//output_adm.txt
342        which was left over, but fails at level 7 & 6)
343    
344    checkpoint61j
345    o pkg/seaice: turn a few hard wired parameters into run time parameters
346    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
347      time in seconds as promised by the usints in seaice_monitor and exf_monitor
348    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
349      that are not cubed-sphere grids
350    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
351    o pkg/ctrl:
352      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
353    o non-hydrostatic (calc_gw.F):
354      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
355      update output of exp. global_ocean.cs32x15.viscA4
356    o remove backward compatibility for thetaMin,phiMin
357      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
358    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
359      interpolated wind field not only for curvilineargrid=.true., but also
360      for a rotated grid (rotateGrid=.true.)
361    o pkg/exf: add capability to bypass interpolation for runoff
362      by setting yet another CPP-flag
363    o eesupp/src, B-grid exchange:
364      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
365    o autodiff
366      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
367      allows to switch to single-prec common blocks;
368      corresponding switch occurs in tamc.h, integer isbyte
369      TAF store directivs "byte" and "kind" seem equivalent;
370      Most tamc.h have been updated correspondingly.
371    
372    checkpoint61i
373    o autodiff:
374      fix autodiff_sore/_restore indices for obcs
375      (spotted by I. Hoteit, M. Mazloff)
376    o pkg/autodiff, pkg/ctrl:
377      Add flag to reduce all tapelev I/O to single-prec.
378      In data.ctrl set
379        doSinglePrecTapelev = .TRUE.
380    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
381      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
382    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
383      real fresh water flux (not yet)
384    o pkg/mdsio & rw:
385     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
386     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
387    o pkg/flt:
388     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
389       init_fixed & ini_varia.
390     - clean-up & simplify linear interpolation S/R:
391       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
392     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
393     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
394     - add vert. coordinate & horiz. indices to output files.
395     - change vertical position in initial condition, from index to depth [m].
396     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
397       (easier to get to a curvilinear grid) ; delX,delY no longer used.
398    o pkg/ggl90: a few modifications:
399     - fix bottom boundary condition, and interpolation of KappaE
400       near top and bottom
401     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
402     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
403     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
404    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
405      (maintain temporary backward compatibility, until next checkpoint)
406    
407    checkpoint61h
408    o pkg/diagnostics with "periodic averaging diagnostics":
409      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
410    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
411    o pkg/obcs: fix loop ranges for balancing code
412    o pkg/flt:
413     - improve criteria for finding which tile owns a float.
414     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
415    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
416      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
417      with ocean biogeo)
418    o pkg/flt:
419     - do some cleaning and fix the restart ;
420     - add output.txt in flt_example/results to get this pkg tested.
421    o genmake2: add an EXTENDED_SRC option and flag.
422       for now, cannot be turned on on command line (only through genmake_local)
423    o pkg/mdsio: read/write vector:
424     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
425     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
426       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
427     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
428      (drop to 4 digits matching for grad). But this test does not look very
429      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
430    
431    checkpoint61g
432    o pkg/flt:
433      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
434       + make OPTIONS file more standard.
435      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
436      - fix _BYTESWAPIO CPP-Flag
437      - standard reading of file-parameter "data.flt"
438      - fix argument list of S/R FLT_RESTART
439      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
440    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
441    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
442      a still unfixed compiler/optimization bug
443    
444    checkpoint61f
445    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
446      update results of global_ocean.cs32x15.icedyn test.
447    o move getcon.F from model/src to pkg/fizhi.
448    o pkg/exf: add parameter for extrapolation of temp up to the surface
449       and option to prevent negative evap (in bulk_largeyeager04 only).
450    o Prather Advection scheme: fix tracer conservation for divergent flow
451      (e.g., when using NonLin Free-Surface).
452    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
453    o gmredi (Visbeck-variable-K):
454     - add more parameters to Visbeck-variable-K.
455     - use a 5 points average for dSigmaR in Visbeck-K calculation
456       (more "homogenous": same stencil and same weights as in dSigmaH)
457     - update output of ideal_2D_oce experiment.
458    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
459      (#undef REAL4_IS_SLOW)
460     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
461       coordinate variable
462     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
463       (surface forcing fields), removes some of the functionality
464     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
465     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
466       probably not all: copy _RS surface flux fields to RL field before
467       calling DIAGNOSTICS_FILL
468     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
469       real*4 (CALL EXCH_*_RS) versions.
470     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
471       (generate new output).
472    
473    checkpoint61e
474    o gmredi (Visbeck-variable-K):
475      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
476      - change computation of Visbeck-K where Slope > Smax :        
477        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
478        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
479    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
480      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
481    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
482    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
483      does not become too large (to avoid precision problems in implicit-diffusion
484      solver); update ideal_2D_oce output.
485    o pkg ggl90:
486      - in ggl90_cal.F: compute only one set of visc/diff, used to
487        step forward TKE/T/S/momentum
488      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
489        have Prandlt =1)
490    o gmredi (fm07):
491      - add lower limit on Transition layer thickness + lower limit on 1/lambda
492      - allow to set few more params from data.gmredi
493    o pkg ggl90:
494          - add missing sqrt(2) factor in computation of mixing length
495            scale in ggl90_calc.F
496            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
497    
498    checkpoint61d
499    o adjoint modifs
500      - adapt to new field rhoInSitu
501      - allow to revert from StoreDynVars2D, StoreDynVars3D
502        to individual fields
503        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
504    o store 3-D (in-situ) density in commom block (DYNVARS.h)
505     - save 1 rho computation.
506     - no longer modify T & S inland when using down_slope pkg.
507    o gad_som : allow to switch to SOM advection for T & S without corresponding
508      pickup files (using new S/R: MDS_CHECK4FILE).
509    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
510      (for useSingleCpuIO to work in multi-threaded)
511    o pkg/shelfice:
512     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
513       with SHELFICEtopoFile in data.shelfice
514     - move code for reading ice shelf topography and modifying hFacC into separate
515       subroutines of the shelfice package
516     - separate initialisation of "fixed" and "variable" variables
517     - kTopC is not (yet) replaced by kSurfC, although this is possible
518    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
519    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
520      and rename:
521      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
522      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
523    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
524    
525    checkpoint61c
526    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
527      to add mass source/sink of fluid in the interior (3-D generalisation
528      of oceanic real-fresh water flux).
529    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
530    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
531    o new pkg: down_slope
532      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
533      - presently, modify T & S inland (dwnslp_calc_rho.F).
534        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
535      - implementation for ocean in P-coords not tested.
536      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
537    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
538      (to facilitate conversion of oceanic pkg to p-coordinate).
539    o change FIND_RHO to FIND_RHO_2D :
540      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
541    o new pkg: cheapaml
542    
543    checkpoint61b
544    o exch2:
545      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
546      - no longer depend on the order sequence (N,S,E,W).
547      - 3rd exchange no longer needed (tested with 24 tiles).
548      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
549      - exch_UV_A-grid readily available (but not yet tested).
550      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
551      (both are no longer needed) in exch_uv: no effect in forward run; but
552       get truncation error differences with adjoint exch.
553    o exch2:
554     - change index-bounds storage (moved from target to local tile,
555       more intuitive this way) ; rename/remove some variables.
556     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
557    
558    checkpoint61a
559    o exch2/matlab-topology-generator:
560      fix bug in index bounds for N-S internal exchange (hard to tell if this
561      had any effect on the solution).
562    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
563      is exceeded
564    o testreport: modify syntax of awk, so that it works also with
565      awk, and not only with nawk and gawk
566    
567    checkpoint61
568    o autodiff
569      Change default for TAF usage by removing argument '-nonew_arg'
570      This changes TAF subroutine argument list (ordering of active var.)
571      Omission of this flag leads to incompatibility w.r.t. TAMC
572      To restore TAMC-compatibility, need following modifs:
573      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
574      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
575      Tested TAF version is 1.9.22
576      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
577    
578    checkpoint60
579    --->>> This is the last checkpoint for which generating the adjoint
580    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
581    --->>> by default.
582    --->>> Future checkpoints will ommit this flag by default.
583    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
584    o pkg/grdchk: Add gradient check to etan0 perturbations.
585    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
586    o pkg/autodiff: more flexibility in zeroadj.
587      model/src: modifying do_oceanic_phys.F accordingly.
588    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
589    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
590      special setup of gmredi for which the adjoint is stable
591      enough for parameter optimization.
592    o bridging the gap between eddy stress and GM.
593      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
594          along with a change in CPP option (now ALLOW_EDDYPSI).
595      -> when using GM w/ GM_AdvForm:
596          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
597          is applied either in the tracer Eq. or in momentum Eq.
598          depending on data.gmredi (intro. GM_InMomAsStress).
599      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
600      The key modifications are in model/src/taueddy_external_forcing.F
601      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
602    
603    checkpoint59r
604    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
605      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
606      fix option to read coriolis(@ cell-corner) from files with CS-grid.
607    o pkg/mnc: add some attributes to standard 1D-coordinate variables
608    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
609      mass points, when using mnc for output
610      - add runtime parameter (missing_value, missing_value_int) to override
611        default (which is the value of getcon('UNDEF'))
612    o pkg/mnc: prepare mnc for the actual use of missing values with the
613      diagnostics package: small fix in mnc_cw_readwrite.template and more
614      initialisation of never used fields
615      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
616      versions
617    o pkg/thsice/thsice_ini_vars.F added default initial values so that
618      thermodynamics sea ice solver does not blow up when some initial fields
619      are missing.
620    o move from external_forcing_surf.F to ini_forcing.F
621      the p-coord. hack consisting in using pLoad to set phi0surf ;
622      update output of tutorial_global_oce_in_p (affected @ truncation level).
623    o Freshen up a bit hs94.1x64x5, notably:
624      remove rotationPeriod and tRef=5*0. (adjoint only), and add
625      exactConserv=.TRUE.
626    o pkg/generic_advdiff:
627      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
628      applies to files where Temperature & Salinity 2nd Order moments are used.
629    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
630      this uses a dynamically allocated internal state data structure
631      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
632      and requires a fortran 90 compiler
633    
634    checkpoint59q
635    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
636       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
637    o Refresh tutorial_global_oce_biogeo, notably:
638      - change bathymetry (put back seamounts in ACC, use hFacs)
639      - change EOS (POLY3 --> JMD95Z)
640      - use Bryan-Lewis vertical diffusivity
641      - use multidimensional advection
642      - remove old virtual virtual in dic pkg, now done through ptracer pkg
643      - change a couple of parameters in dic pkg
644    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
645    o pkg/obcs: change default to OBCSfixTopo = .true.,
646      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
647      - replace "debugMode" with "debugLevel .GE. debLevB"
648    o implementation of TAF directives for gchem,cfc,dic
649    o remove "exp5" (replaced by tutorial_deep_convection).
650    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
651      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
652      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
653      --> changes results in exp4, seaice_obcs
654    o tutorial_deep_convection :
655      update the set-up and increase resolution and domain size ; start
656      from pseudo initial conditions = output at t=120mn in order to see
657      something happening when running testreport.
658    o pkg/seaice: add os7mp as an advection scheme
659                  add check for advection schemes
660                  add a flag for restoring T and S underneath sea ice
661    o pkg/my82: add netcdf-support and diagnostics
662    o thsice pkg:
663      - Now hsMax limits snow height by turning it into ice following
664        flooding scheme (and now conserving energy)
665      - Slight rewriting of the formula in thsice_calc_thick.F
666      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
667      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
668    
669    checkpoint59p
670    o gchem / dic / cfc :
671      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
672      - add new parameter files: "data.dic" & "data.cfc" ;
673      - various re-arrangement in initialisation & header file ;
674      - fix tutorial_global_oce_biogeo for multi-threaded test.
675    o pkg/dic: test for "pickup_dic" file when restarting ;
676      if no pickup-file, can restart with a re-initialised pH (same as it did
677      before) providing pickupStrictlyMatch is set to False.
678    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
679      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
680    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
681      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
682    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
683     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
684       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
685    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
686       scheme to use for vorticty-term ;
687     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
688       (with default selectVortScheme, return to original discretisation)
689     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
690    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
691    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
692      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
693      also fix diagnostics VISCAHW & VISCA4W.
694    
695    checkpoint59o
696    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
697    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
698      move a few statemens out the main loop into separate loops
699    o pkg/shelfice:
700      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
701        (kg/m^2/s), does not break tests, because in verification/isomip,
702        rhoConstFresh=rhoConst (by accident)
703      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
704      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
705        new file model/src/seawater.F, so that they are available for all pkgs.
706      - convert potential temperature into in-situ temperature. This changes the
707        isomip tests => update tests
708    o add a flag writePickupAtEnd (default=true) to be able to suppress
709      writing a pickup at the last timestep
710    o tools/mpack-1.6 :
711      - disable automake (not working) and autoconf (not needed).
712      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
713        also cleaner with much less compilation warnings.
714    o pkg/profiles:
715      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
716      (for "less than 32 characters name" compiler requirement)
717    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
718      conditions that have a different sampling frequency than S/T/U/V obcs
719    o pkg/diagnostics (stats-diags):
720      - fix global Min/Max in case 1 processor get only empty tiles
721    o genmake2: replace (4 times)
722         make genmake_tc_1.o >> genmake_warnings 2>&1
723      with
724         COMM="$CC $CFLAGS -c genmake_tc_1.c"
725         echo $COMM >> genmake_warnings
726         $COMM >> genmake_warnings 2>&1
727      to make genmake2 always see the value of CC as specified in the optfile.
728    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
729      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
730      - modify verification advect_cs test to test SOM-advection on CS-grid.
731    o pkg/ctrl:
732      - Rewrite of ctrl_map_ini_ecco.F,
733        introducing a generic routine (ctrl_map_ini_gen.F).
734      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
735    
736    checkpoint59n
737    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
738      number in dedicate array "hdiag":
739      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
740        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
741      - many small changes (integer format) for large number of diagnostics
742      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
743        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
744    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
745      usingSphericalGrid, this allows to define the rotated grid coordinates
746      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
747      geographical coordinates according to the inverse of the rotation defined
748      by the Euler angles, so that Coriolis parameter and online-interpolation by
749      exf works with the geographical coordinates on XC/YC/XG/YG.
750      Naturally, this feature does not work with all packages, so some
751      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
752      profiles), because there the coordinates are assumed to be regular
753      spherical grid coordinates.
754    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
755      - introduce isopycnal diffusion coefficient control.
756    o tools/adjoint_options:
757      - additional control vector components.
758    o pkg/mnc: have mnc create marginally meaning full coordinate variables
759      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
760    o pkg/mypackage:
761      - add example of read/write pickup for state-var ;
762      - add entry points to the main code for state-vars diags & write-pickup.
763    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
764      transitions for useExfYearlyFields
765      - add new subroutine that determines the file to read from for
766        use*YearlyFields = .TRUE. and .FALSE.
767      - add a verification experiment to global_with_exf that tests
768        useExfYearlyFields with USE_EXF_INTERPOLATION defined
769    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
770      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
771      subroutines (which could be generated from a template, because they are
772      almost identical), for now they are included in obcs_prescribe_read.F for
773      simplicity
774    o pkg/exf:
775      - add a little more diagnostic to exf_interp_read (in analogy to
776        mds_read_field, can be turned off with debugLevel < debugLevA=1)
777      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
778        ugly but fast by unrolling short inner loops, inserting a unroll=8
779        directive in routine lagran, and splitting a loop and making do while the
780        outermost loop (the latter requires the intoduction of index arrays)
781    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
782    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
783      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
784    o verification/seaice_obcs: updated for restart test and latest options
785    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
786      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
787      for now this is only available for the C-grid code and also within
788      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
789    
790    checkpoint59m
791    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
792      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
793    o gad_som : fix flux output (& diagnostics) to have same units as other  
794      advection scheme fluxes (was previously multiplied by deltaT).  
795    o added verification/seaice_obcs both to test seaice open boundaries
796      and to provide an example matlab scrpt for generating them
797    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
798    o pkg/salt_plume: clean up salt_plume_frac.F to
799      remove redundancy in PlumeMethod 1 and 4
800    o pkg/kpp: added saltplume diagnostics
801    o pkg/obcs and pkg/seaice:
802      - do not set uice and vice to zero when OB*icefile are unspecified
803      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
804      - moved seaice tracer obcs after call to seaice_growth
805    o pkg/salt_plume: added various options for salt plume depth
806      criterion and for vertical distribution of the salt
807    
808    checkpoint59l
809    o pkg/ptracers: new version of ptracers pickup:
810      read meta file and write only fields which are needed to restart.
811      ( same logic as main pickup file ; also using pickupStrictlyMatch )
812    o pkg/seaice:
813      - add timescale for melting due to warm mixed layer as a means of
814        setting SEAICE_availHeatFrac more conveniently
815      - add a CPP-flag/runtime parameter check for flooding algorithm
816      - reformulated availHeat in seaice_growth.F to be independent of AREA
817    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
818      unit changes
819    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
820    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
821      SX vector computer.
822    o pkg/seaice:
823      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
824        seaice forcing fields can now be read only through pkg/exf
825      - removed some unused halos
826    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
827    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
828      or U/VICE from U/VWIND before computing U/VSTRESS
829    
830    checkpoint59k
831    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
832      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
833    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
834      all experiments pass when compile with un-initialised var. checking option.
835    o added pkg/salt_plume
836    o script to test restart (for now, in MITgcm_contrib/jmc_script)
837    o pkg/seaice: new read/write pickup version.
838      read meta file and write only fields which are needed to restart.
839      ( same logic as main pickup file ; also using pickupStrictlyMatch )
840    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
841    o lab_sea.hb87: modify the domain & update output.hb87.txt :
842      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
843      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
844      process. Fixed here by closing the domain at the Northern boundary.
845    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
846    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
847      a set of consecutive levels in/from a 3-D array.
848    o pkg/ptracers:
849      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
850      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
851    
852    checkpoint59j
853    o in pkgs: dic, obcs, offline, rbcs:
854      standard way to compute coeff. for time interpolation between 2 time reccords
855      which retains full precision (& make results less dependent on compiler).
856      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
857    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
858      packages instead of reading ice cover and wind speed separately
859    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
860     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
861      to allow to compile customized code before the update)
862    o cleaning-up:
863      - fix CPP instruction syntax in pkg/obcs
864      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
865        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
866      - fix some threads issue in IO parts.
867    o pkg/dic:
868      - add tons of "_d 0" (--> much better testreports !)
869       and then update outputs of tutorial_global_oce_biogeo
870    o pkg/mom_fluxform:
871      add a special version of momentum advection intended to conserve momentum
872      next to a bathymetry step or a coastline edge. (default = off = #undef)
873    o new read/write pickup version:
874      - for now, only implemented for main (mdsio) pickup file.
875      - write out only what is needed to restart; merge pickup_nh , pickup_ph
876        and main pickup together.
877      - read meta file; read only what is needed to restart; stop if a field
878        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
879        if it make sense (even if the restart is not perfect).
880      - if no meta file, assume that pickup to read corresponds exactly to
881        a pickup that would currently be written.
882      - read pickup written in the old format (until checkpoint59i) if it
883        recognizes an old meta file (no field-list).
884      - add a meta file in exp. which starts from a pickup: 2 cases:
885        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
886         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
887        b) a meta file describing the content of the associated pickup file
888         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
889    o pkg/mdsio & pkg/rw:
890      - new routine to read a meta file ; new set of routine to read
891        Multiple-fields file (with meta file).
892    o added open boundary conditions capability for seaice
893        HSNOW, HSALT, UICE, and VICE
894    
895    checkpoint59i
896    o adjoint:
897      * fix multiDimAdvection adjoint
898        (partial recomputation problem by TAF for fVerT(:,:,kDown)
899        and comlev1 size definition (maxpass vs. max. number of tracers)
900      * verification/global_ocean.90x45x15 adjoint now tests
901        NLFS and multiDimAdvection using DST3 (=30)
902      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
903    o pkg/kpp: add "_d 0" to real constant (if missing);
904      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
905      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
906    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
907      for internal parameters related to restart process (formerly from PARAMS.h)
908      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
909    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
910      as argument. (only atm2d & obcs write_pickup have not yet been updated)
911    o pkg/monitor:
912      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
913      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
914      - account for deep Atmosphere factor and density factor (anelastic)
915    o added open boundary conditions capability for seaice HEFF and AREA
916    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
917      thermodynamics
918      - requires a little reorganization, which affects the testreport results
919        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
920        so that now the conservative form is tested
921      - add a few comments
922    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
923    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
924    o add new diagnostics to seaice: advective, diffusive fluxes (only for
925      multidim-advection, for scheme 2 they are not filled) and transports,
926      thermodynamic growth rates
927    o change units of EmPmR (inside the code, + within coupling interface)
928      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
929      Affects results @ truncation level (cg2d match) and update output of
930       experiments: lab_sea(6), global_ocean.90x40x15(10),
931      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
932      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
933      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
934      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
935    
936    checkpoint59h
937    o pkg/exf:
938      - improve vectorization by moving if-statement out of loops in
939        exf_mapfields, exf_radiation
940      - exf_bulkformulae.F: introduce 2D fields and vectorize code
941    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
942    o testreport:
943      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
944        monitor & update offline_exf_seaice exp. output.
945      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
946    o pkg/seaice:
947      - bug fix in the evp solver: boundary conditions were affected be
948        masking of zMax/zMin (changes results)
949      - minor bug fix in boundary conditions in seaice_calc_strainrates
950        (changes results for no_slip)
951      - seaice_lsr.F: make interpolation of eta dependent on boundaries
952      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
953      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
954        stress formulation and no-slip boundary conditions
955    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
956      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
957    o pkg/seaice: a first HSALT time stepping equation has been checked in
958    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
959      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
960      without requiring DO-IF statements
961    o pkg/thsice:
962      use continuous power-law function for partition of energy between lateral
963      melting/freezing and thinning/thickening ; old code using step function
964      still available with #undef THSICE_FRACEN_POWERLAW
965      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
966    o testreport: change AD testing : check against results/output_adm.txt
967      using same scripts as for forward test.
968    
969    checkpoint59g
970    o adjoint testing: in preparation for changing testreport:
971      - output format: cost and grad written on separated lines
972      - ad output results in directory "results" (instead of "results_ad")
973    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
974    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
975    o pkg/ecco: allow user defined cost function contributions
976    o testreport:
977      Allow to choose (per experiment) the list of tested output variables
978       and the main variable (used to issue a pass/FAIL ) ;
979      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
980      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
981      Also modify printing of summary:
982       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
983       b) echo the list of tested variables in the individual summary.txt of
984          each experiment.
985    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
986      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
987      (but still depend on the tile decompostion of the domain).
988    o pkg/seaice: change a discretization detail to make the B-grid code
989      "more symmetric". This change is likely to remove all "ridges/leads" that
990      where quasi-aligned with the grid in B-grid solutions. It may also be
991      the solution to the stress coupling issues with the B-grid.
992    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
993      remove .cvsignore from input dir. (since testreport no longer run here).
994    o pkg/thsice:
995     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
996     - fix reshaping of sea-ice just after advection:
997       melt all the ice only if ice-volume is too small.
998     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
999       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1000     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1001    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1002      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1003    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1004      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1005      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1006      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1007      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1008      -> update output.txt
1009    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1010     this affects truncation error: -> update output.txt of exp:
1011      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1012      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1013    
1014    checkpoint59f
1015    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1016    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1017      a bounded range (in forward mode)
1018    o pkg/ecco, ctrl, autodiff and mom_common:
1019     internal parameter controls, completements of implementations
1020    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1021    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1022      (not seem any difference in testing results).
1023    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1024       at face corners.
1025    o pkg/generic_advdiff:
1026     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1027      loop range indices for computing vertical advection tendency
1028      and do the calculation in the interior only (no overlap) ;
1029      for now, only implemented for SOM advection (to save CPU time).
1030     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1031    o exch2 adjoint
1032      First set of changes:
1033      - add exch2 hand-written adjoint templates
1034      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1035        This will require cleanup in pkg/autodiff/*.F
1036        (changed routines currently kept separate in verif. code/)
1037      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1038        that used to hide exch2 or cubed-sphere specific code
1039        (commented via 'cph-exch2')
1040    o pkg/seaice
1041      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1042    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1043       output of global_ocean.cs32x15.thsice .
1044    
1045    checkpoint59e
1046    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1047      for B-grid vector (not yet tested) and C-grid vector (<- only used
1048      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1049    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1050      (#ifdef ALLOW_SALT_PLUME)
1051    o gather_2d/scatter_2d: removed halo regions
1052    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1053      scheme and the corresponding test case (under front_relax dir). For now,
1054      only available with Skew-flux form and not yet tested in realistic set-up.
1055      adjoint: store directives updated, but gradient checks deteriorated,
1056      so maybe GM/Redi adjoint is now broken.
1057    o seaice adjoint
1058      * add AREA, HEFF, HSNOW as control variable
1059        (should not change lab_sea results)
1060      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1061    o pkg/seaice:
1062      * added computation of saltFlux in seaice_growth;
1063        For time being, sea ice salinity is assumed constant
1064        contribution of snow flooding to freshening of sea ice is neglected.
1065        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1066        defaults to 0.0 in order to maintain backward compatibility.
1067        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1068      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1069      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1070        heat content used to melt or grow ice
1071      * commented out cap of HICE: it helps keep ice thinner
1072      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1073      * applied OBCS T/S mask to HEFFM sea ice mask
1074    
1075    checkpoint59d
1076    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1077     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1078     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1079    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1080     and change default value of parameter "GM_Small_Number";
1081     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1082       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1083       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1084    o pkg/ecco: cost function when applying pkg/smooth to controls
1085    o pkg/ctrl: add forcingPrecond run time parameter
1086    o pkg/seaice:
1087     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1088     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1089       changes verification/lab_sea
1090     - rearrange implicit part of u-equation in LSR solver to make it easier to
1091       read, understand, and debug. This causes changes at the truncation level.
1092     - fix (serious) bug in the boundary conditions (sign error in the implicit
1093       part) of the LSR solver. Changes all LSR results.
1094     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1095       is initilized with small values - does not change lab_sea results.
1096     - added HsnowFile initialization capability
1097    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1098     initialization of pkg/smooth and application to control vector
1099    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1100    o dependencies: pkg/profiles requires pkg/cal
1101    o pkg/profiles:
1102     - added option ALLOW_PROFILES_GENERICGRID
1103         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1104         that interpolation information (grid points and coefficients) is provided
1105         within the netcdf input files.
1106         -> sample matlab scripts can be found in MITgcm_contrib/gael
1107         that allow you to prepare netcdf input files.
1108     - also modified: cleaner include statements, cleaner error print statements,
1109       cleaner stops when error, and more tests of the netcdf input files consistency.
1110    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1111    o pkg/seaice:
1112     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1113       requires a new routine: seaice_diagnostics_fill.F
1114     - make sure that seaice does not move if not forced (pressure replacement
1115       method, Hibler and Ip, 1995), changes results
1116     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1117     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1118       It is turned off by default (=-1.), because it changes the results.
1119     - make it possible to read AREA from a file, too.
1120    
1121    checkpoint59c
1122    o add S/R and diagnostics for oceanic mixed-layer depth
1123    o move GMRedi call after all vertical mixing schemes (including KPP)
1124    o pkg/thsice:
1125     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1126      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1127    o pkg/obcs:
1128     - bug fix for balance code
1129    o pkg/seaice:
1130      - allow values of SEAICE_elasticParm > 1
1131      - add new parameter SEAICE_evpTauRelax as an alternative
1132        to SEAICE_elasticParm
1133      - make lsr boundary conditions free slip (by default), changes result
1134      - add code for no slip boundary conditions for lsr
1135      - set minimum of zeta to zero (and not 4e8) (changes results)
1136      - add a cap on AREA after advecting AREA if seaice_growth is not called
1137    o change calculation of Visbeck K:
1138      - no longer depend on tapering scheme; instead, compute slope (limited
1139        by GM_maxSlope). this is equivalent to what was comuted before with
1140        clipping or linear tappering.
1141      - fix vertical averaging (wrong by 1/2 level)
1142      - leave the old version (but will not be maintained) within
1143        #ifdef OLD_VISBECK_CALC / #endif
1144      - update output of exp. ideal_2D_oce
1145    o change error catch in calc_r_star to improve vectorization
1146    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1147      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1148    o adjoint:
1149      Re-organized adjoint checkpointing according to Matt Mazloff
1150      (but with modifs/completions/cleanups)
1151      Storing is now bundled into large arrays to optimized I/O
1152      (and second step in cleanup of the_main_loop)
1153    
1154    checkpoint59b
1155    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1156      - export/import (between ocean & coupler) fields needed for ocean DIC.
1157    o pkg/seaice:
1158      - get rid of three more exchanges seaice_calc_viscosities (required
1159        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1160      - bug fix in seaice_ocean_stress (update of lab_sea required)
1161      - reduce loop boundaries to necessary minimum also in seaice_evp
1162      - go back to the old way of computing deltaC/Z as the adjoint likes that
1163        better
1164    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1165      passive tracer to an Age Tracer) + update output.txt
1166    o pkg/exf:
1167      - implement A-grid / C-grid selection for wind-stress input files.
1168      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1169      for now, in exf_bulk_largeyeager04.F only :
1170      - change implementation for case where windspeed + 2. components wind-stress
1171        are read-in. AND use rhoConstFresh to convert evap.
1172    o pkg/seaice:
1173      - use correct EXCH_UV for wind-forcing (on A-grid).
1174      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1175        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1176    o pkg/exf:
1177      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1178      EXF_INTERPOLATION:
1179      - merge global_with_exf/code version of exf_interp_read.F
1180        to the main code ;
1181      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1182        reading the file ; Important: This options needs to be defined to recover
1183        previous code.
1184        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1185      - no longer loose real*8 precision along the way when using exf_iprec=64.
1186  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1187      - change discretisation of evp-solver in order to avoid another exchange
1188        (changes lab_sea) and clean up a little
1189      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1190        help the adjoint (this also changes the results slightly)
1191      - add a few "_d 0" where they had been missing in seaice_evp.F
1192      - cleaning up: remove unused seaice_calc_rhs.F
