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

373    o pkg/obcs: fix loop ranges for balancing code
374    o pkg/flt:
375     - improve criteria for finding which tile owns a float.
376     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
377    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
378      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
379      with ocean biogeo)
380    o pkg/flt:
381     - do some cleaning and fix the restart ;
382     - add output.txt in flt_example/results to get this pkg tested.
383    o genmake2: add an EXTENDED_SRC option and flag.
384       for now, cannot be turned on on command line (only through genmake_local)
385    o pkg/mdsio: read/write vector:
386     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
387     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
388       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
389     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
390      (drop to 4 digits matching for grad). But this test does not look very
391      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
392    
393    checkpoint61g
394    o pkg/flt:
395      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
396       + make OPTIONS file more standard.
397      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
398      - fix _BYTESWAPIO CPP-Flag
399      - standard reading of file-parameter "data.flt"
400      - fix argument list of S/R FLT_RESTART
401      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
402    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
403    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
404      a still unfixed compiler/optimization bug
405    
406    checkpoint61f
407    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
408      update results of global_ocean.cs32x15.icedyn test.
409    o move getcon.F from model/src to pkg/fizhi.
410    o pkg/exf: add parameter for extrapolation of temp up to the surface
411       and option to prevent negative evap (in bulk_largeyeager04 only).
412    o Prather Advection scheme: fix tracer conservation for divergent flow
413      (e.g., when using NonLin Free-Surface).
414    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
415    o gmredi (Visbeck-variable-K):
416     - add more parameters to Visbeck-variable-K.
417     - use a 5 points average for dSigmaR in Visbeck-K calculation
418       (more "homogenous": same stencil and same weights as in dSigmaH)
419     - update output of ideal_2D_oce experiment.
420    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
421      (#undef REAL4_IS_SLOW)
422     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
423       coordinate variable
424     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
425       (surface forcing fields), removes some of the functionality
426     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
427     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
428       probably not all: copy _RS surface flux fields to RL field before
429       calling DIAGNOSTICS_FILL
430     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
431       real*4 (CALL EXCH_*_RS) versions.
432     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
433       (generate new output).
434    
435    checkpoint61e
436    o gmredi (Visbeck-variable-K):
437      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
438      - change computation of Visbeck-K where Slope > Smax :        
439        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
440        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
441    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
442      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
443    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
444    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
445      does not become too large (to avoid precision problems in implicit-diffusion
446      solver); update ideal_2D_oce output.
447    o pkg ggl90:
448      - in ggl90_cal.F: compute only one set of visc/diff, used to
449        step forward TKE/T/S/momentum
450      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
451        have Prandlt =1)
452    o gmredi (fm07):
453      - add lower limit on Transition layer thickness + lower limit on 1/lambda
454      - allow to set few more params from data.gmredi
455    o pkg ggl90:
456          - add missing sqrt(2) factor in computation of mixing length
457            scale in ggl90_calc.F
458            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
459    
460    checkpoint61d
461    o adjoint modifs
462      - adapt to new field rhoInSitu
463      - allow to revert from StoreDynVars2D, StoreDynVars3D
464        to individual fields
465        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
466    o store 3-D (in-situ) density in commom block (DYNVARS.h)
467     - save 1 rho computation.
468     - no longer modify T & S inland when using down_slope pkg.
469    o gad_som : allow to switch to SOM advection for T & S without corresponding
470      pickup files (using new S/R: MDS_CHECK4FILE).
471    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
472      (for useSingleCpuIO to work in multi-threaded)
473    o pkg/shelfice:
474     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
475       with SHELFICEtopoFile in data.shelfice
476     - move code for reading ice shelf topography and modifying hFacC into separate
477       subroutines of the shelfice package
478     - separate initialisation of "fixed" and "variable" variables
479     - kTopC is not (yet) replaced by kSurfC, although this is possible
480    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
481    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
482      and rename:
483      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
484      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
485    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
486    
487    checkpoint61c
488    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
489      to add mass source/sink of fluid in the interior (3-D generalisation
490      of oceanic real-fresh water flux).
491    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
492    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
493    o new pkg: down_slope
494      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
495      - presently, modify T & S inland (dwnslp_calc_rho.F).
496        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
497      - implementation for ocean in P-coords not tested.
498      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
499    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
500      (to facilitate conversion of oceanic pkg to p-coordinate).
501    o change FIND_RHO to FIND_RHO_2D :
502      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
503    o new pkg: cheapaml
504    
505    checkpoint61b
506    o exch2:
507      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
508      - no longer depend on the order sequence (N,S,E,W).
509      - 3rd exchange no longer needed (tested with 24 tiles).
510      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
511      - exch_UV_A-grid readily available (but not yet tested).
512      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
513      (both are no longer needed) in exch_uv: no effect in forward run; but
514       get truncation error differences with adjoint exch.
515    o exch2:
516     - change index-bounds storage (moved from target to local tile,
517       more intuitive this way) ; rename/remove some variables.
518     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
519    
520    checkpoint61a
521    o exch2/matlab-topology-generator:
522      fix bug in index bounds for N-S internal exchange (hard to tell if this
523      had any effect on the solution).
524    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
525      is exceeded
526    o testreport: modify syntax of awk, so that it works also with
527      awk, and not only with nawk and gawk
528    
529    checkpoint61
530    o autodiff
531      Change default for TAF usage by removing argument '-nonew_arg'
532      This changes TAF subroutine argument list (ordering of active var.)
533      Omission of this flag leads to incompatibility w.r.t. TAMC
534      To restore TAMC-compatibility, need following modifs:
535      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
536      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
537      Tested TAF version is 1.9.22
538      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
539    
540    checkpoint60
541    --->>> This is the last checkpoint for which generating the adjoint
542    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
543    --->>> by default.
544    --->>> Future checkpoints will ommit this flag by default.
545    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
546    o pkg/grdchk: Add gradient check to etan0 perturbations.
547    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
548    o pkg/autodiff: more flexibility in zeroadj.
549      model/src: modifying do_oceanic_phys.F accordingly.
550    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
551    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
552      special setup of gmredi for which the adjoint is stable
553      enough for parameter optimization.
554    o bridging the gap between eddy stress and GM.
555      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
556          along with a change in CPP option (now ALLOW_EDDYPSI).
557      -> when using GM w/ GM_AdvForm:
558          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
559          is applied either in the tracer Eq. or in momentum Eq.
560          depending on data.gmredi (intro. GM_InMomAsStress).
561      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
562      The key modifications are in model/src/taueddy_external_forcing.F
563      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
564    
565    checkpoint59r
566    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
567      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
568      fix option to read coriolis(@ cell-corner) from files with CS-grid.
569    o pkg/mnc: add some attributes to standard 1D-coordinate variables
570    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
571      mass points, when using mnc for output
572      - add runtime parameter (missing_value, missing_value_int) to override
573        default (which is the value of getcon('UNDEF'))
574    o pkg/mnc: prepare mnc for the actual use of missing values with the
575      diagnostics package: small fix in mnc_cw_readwrite.template and more
576      initialisation of never used fields
577      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
578      versions
579    o pkg/thsice/thsice_ini_vars.F added default initial values so that
580      thermodynamics sea ice solver does not blow up when some initial fields
581      are missing.
582    o move from external_forcing_surf.F to ini_forcing.F
583      the p-coord. hack consisting in using pLoad to set phi0surf ;
584      update output of tutorial_global_oce_in_p (affected @ truncation level).
585    o Freshen up a bit hs94.1x64x5, notably:
586      remove rotationPeriod and tRef=5*0. (adjoint only), and add
587      exactConserv=.TRUE.
588    o pkg/generic_advdiff:
589      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
590      applies to files where Temperature & Salinity 2nd Order moments are used.
591    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
592      this uses a dynamically allocated internal state data structure
593      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
594      and requires a fortran 90 compiler
595    
596    checkpoint59q
597    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
598       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
599    o Refresh tutorial_global_oce_biogeo, notably:
600      - change bathymetry (put back seamounts in ACC, use hFacs)
601      - change EOS (POLY3 --> JMD95Z)
602      - use Bryan-Lewis vertical diffusivity
603      - use multidimensional advection
604      - remove old virtual virtual in dic pkg, now done through ptracer pkg
605      - change a couple of parameters in dic pkg
606    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
607    o pkg/obcs: change default to OBCSfixTopo = .true.,
608      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
609      - replace "debugMode" with "debugLevel .GE. debLevB"
610    o implementation of TAF directives for gchem,cfc,dic
611    o remove "exp5" (replaced by tutorial_deep_convection).
612    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
613      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
614      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
615      --> changes results in exp4, seaice_obcs
616    o tutorial_deep_convection :
617      update the set-up and increase resolution and domain size ; start
618      from pseudo initial conditions = output at t=120mn in order to see
619      something happening when running testreport.
620    o pkg/seaice: add os7mp as an advection scheme
621                  add check for advection schemes
622                  add a flag for restoring T and S underneath sea ice
623    o pkg/my82: add netcdf-support and diagnostics
624    o thsice pkg:
625      - Now hsMax limits snow height by turning it into ice following
626        flooding scheme (and now conserving energy)
627      - Slight rewriting of the formula in thsice_calc_thick.F
628      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
629      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
630    
631    checkpoint59p
632    o gchem / dic / cfc :
633      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
634      - add new parameter files: "data.dic" & "data.cfc" ;
635      - various re-arrangement in initialisation & header file ;
636      - fix tutorial_global_oce_biogeo for multi-threaded test.
637    o pkg/dic: test for "pickup_dic" file when restarting ;
638      if no pickup-file, can restart with a re-initialised pH (same as it did
639      before) providing pickupStrictlyMatch is set to False.
640    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
641      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
642    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
643      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
644    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
645     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
646       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
647    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
648       scheme to use for vorticty-term ;
649     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
650       (with default selectVortScheme, return to original discretisation)
651     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
652    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
653    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
654      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
655      also fix diagnostics VISCAHW & VISCA4W.
656    
657    checkpoint59o
658    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
659    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
660      move a few statemens out the main loop into separate loops
661    o pkg/shelfice:
662      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
663        (kg/m^2/s), does not break tests, because in verification/isomip,
664        rhoConstFresh=rhoConst (by accident)
665      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
666      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
667        new file model/src/seawater.F, so that they are available for all pkgs.
668      - convert potential temperature into in-situ temperature. This changes the
669        isomip tests => update tests
670    o add a flag writePickupAtEnd (default=true) to be able to suppress
671      writing a pickup at the last timestep
672    o tools/mpack-1.6 :
673      - disable automake (not working) and autoconf (not needed).
674      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
675        also cleaner with much less compilation warnings.
676    o pkg/profiles:
677      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
678      (for "less than 32 characters name" compiler requirement)
679    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
680      conditions that have a different sampling frequency than S/T/U/V obcs
681    o pkg/diagnostics (stats-diags):
682      - fix global Min/Max in case 1 processor get only empty tiles
683    o genmake2: replace (4 times)
684         make genmake_tc_1.o >> genmake_warnings 2>&1
685      with
686         COMM="$CC $CFLAGS -c genmake_tc_1.c"
687         echo $COMM >> genmake_warnings
688         $COMM >> genmake_warnings 2>&1
689      to make genmake2 always see the value of CC as specified in the optfile.
690    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
691      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
692      - modify verification advect_cs test to test SOM-advection on CS-grid.
693    o pkg/ctrl:
694      - Rewrite of ctrl_map_ini_ecco.F,
695        introducing a generic routine (ctrl_map_ini_gen.F).
696      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
697    
698    checkpoint59n
699    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
700      number in dedicate array "hdiag":
701      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
702        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
703      - many small changes (integer format) for large number of diagnostics
704      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
705        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
706    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
707      usingSphericalGrid, this allows to define the rotated grid coordinates
708      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
709      geographical coordinates according to the inverse of the rotation defined
710      by the Euler angles, so that Coriolis parameter and online-interpolation by
711      exf works with the geographical coordinates on XC/YC/XG/YG.
712      Naturally, this feature does not work with all packages, so some
713      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
714      profiles), because there the coordinates are assumed to be regular
715      spherical grid coordinates.
716    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
717      - introduce isopycnal diffusion coefficient control.
718    o tools/adjoint_options:
719      - additional control vector components.
720    o pkg/mnc: have mnc create marginally meaning full coordinate variables
721      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
722    o pkg/mypackage:
723      - add example of read/write pickup for state-var ;
724      - add entry points to the main code for state-vars diags & write-pickup.
725    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
726      transitions for useExfYearlyFields
727      - add new subroutine that determines the file to read from for
728        use*YearlyFields = .TRUE. and .FALSE.
729      - add a verification experiment to global_with_exf that tests
730        useExfYearlyFields with USE_EXF_INTERPOLATION defined
731    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
732      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
733      subroutines (which could be generated from a template, because they are
734      almost identical), for now they are included in obcs_prescribe_read.F for
735      simplicity
736    o pkg/exf:
737      - add a little more diagnostic to exf_interp_read (in analogy to
738        mds_read_field, can be turned off with debugLevel < debugLevA=1)
739      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
740        ugly but fast by unrolling short inner loops, inserting a unroll=8
741        directive in routine lagran, and splitting a loop and making do while the
742        outermost loop (the latter requires the intoduction of index arrays)
743    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
744    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
745      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
746    o verification/seaice_obcs: updated for restart test and latest options
747    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
748      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
749      for now this is only available for the C-grid code and also within
750      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
751    
752    checkpoint59m
753    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
754      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
755    o gad_som : fix flux output (& diagnostics) to have same units as other  
756      advection scheme fluxes (was previously multiplied by deltaT).  
757    o added verification/seaice_obcs both to test seaice open boundaries
758      and to provide an example matlab scrpt for generating them
759    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
760    o pkg/salt_plume: clean up salt_plume_frac.F to
761      remove redundancy in PlumeMethod 1 and 4
762    o pkg/kpp: added saltplume diagnostics
763    o pkg/obcs and pkg/seaice:
764      - do not set uice and vice to zero when OB*icefile are unspecified
765      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
766      - moved seaice tracer obcs after call to seaice_growth
767    o pkg/salt_plume: added various options for salt plume depth
768      criterion and for vertical distribution of the salt
769    
770    checkpoint59l
771    o pkg/ptracers: new version of ptracers pickup:
772      read meta file and write only fields which are needed to restart.
773      ( same logic as main pickup file ; also using pickupStrictlyMatch )
774    o pkg/seaice:
775      - add timescale for melting due to warm mixed layer as a means of
776        setting SEAICE_availHeatFrac more conveniently
777      - add a CPP-flag/runtime parameter check for flooding algorithm
778      - reformulated availHeat in seaice_growth.F to be independent of AREA
779    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
780      unit changes
781    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
782    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
783      SX vector computer.
784    o pkg/seaice:
785      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
786        seaice forcing fields can now be read only through pkg/exf
787      - removed some unused halos
788    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
789    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
790      or U/VICE from U/VWIND before computing U/VSTRESS
791    
792    checkpoint59k
793    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
794      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
795    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
796      all experiments pass when compile with un-initialised var. checking option.
797    o added pkg/salt_plume
798    o script to test restart (for now, in MITgcm_contrib/jmc_script)
799    o pkg/seaice: new read/write pickup version.
800      read meta file and write only fields which are needed to restart.
801      ( same logic as main pickup file ; also using pickupStrictlyMatch )
802    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
803    o lab_sea.hb87: modify the domain & update output.hb87.txt :
804      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
805      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
806      process. Fixed here by closing the domain at the Northern boundary.
807    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
808    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
809      a set of consecutive levels in/from a 3-D array.
810    o pkg/ptracers:
811      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
812      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
813    
814    checkpoint59j
815    o in pkgs: dic, obcs, offline, rbcs:
816      standard way to compute coeff. for time interpolation between 2 time reccords
817      which retains full precision (& make results less dependent on compiler).
818      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
819    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
820      packages instead of reading ice cover and wind speed separately
821    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
822     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
823      to allow to compile customized code before the update)
824    o cleaning-up:
825      - fix CPP instruction syntax in pkg/obcs
826      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
827        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
828      - fix some threads issue in IO parts.
829    o pkg/dic:
830      - add tons of "_d 0" (--> much better testreports !)
831       and then update outputs of tutorial_global_oce_biogeo
832    o pkg/mom_fluxform:
833      add a special version of momentum advection intended to conserve momentum
834      next to a bathymetry step or a coastline edge. (default = off = #undef)
835    o new read/write pickup version:
836      - for now, only implemented for main (mdsio) pickup file.
837      - write out only what is needed to restart; merge pickup_nh , pickup_ph
838        and main pickup together.
839      - read meta file; read only what is needed to restart; stop if a field
840        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
841        if it make sense (even if the restart is not perfect).
842      - if no meta file, assume that pickup to read corresponds exactly to
843        a pickup that would currently be written.
844      - read pickup written in the old format (until checkpoint59i) if it
845        recognizes an old meta file (no field-list).
846      - add a meta file in exp. which starts from a pickup: 2 cases:
847        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
848         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
849        b) a meta file describing the content of the associated pickup file
850         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
851    o pkg/mdsio & pkg/rw:
852      - new routine to read a meta file ; new set of routine to read
853        Multiple-fields file (with meta file).
854    o added open boundary conditions capability for seaice
855        HSNOW, HSALT, UICE, and VICE
856    
857    checkpoint59i
858    o adjoint:
859      * fix multiDimAdvection adjoint
860        (partial recomputation problem by TAF for fVerT(:,:,kDown)
861        and comlev1 size definition (maxpass vs. max. number of tracers)
862      * verification/global_ocean.90x45x15 adjoint now tests
863        NLFS and multiDimAdvection using DST3 (=30)
864      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
865    o pkg/kpp: add "_d 0" to real constant (if missing);
866      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
867      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
868    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
869      for internal parameters related to restart process (formerly from PARAMS.h)
870      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
871    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
872      as argument. (only atm2d & obcs write_pickup have not yet been updated)
873    o pkg/monitor:
874      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
875      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
876      - account for deep Atmosphere factor and density factor (anelastic)
877    o added open boundary conditions capability for seaice HEFF and AREA
878    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
879      thermodynamics
880      - requires a little reorganization, which affects the testreport results
881        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
882        so that now the conservative form is tested
883      - add a few comments
884    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
885    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
886    o add new diagnostics to seaice: advective, diffusive fluxes (only for
887      multidim-advection, for scheme 2 they are not filled) and transports,
888      thermodynamic growth rates
889    o change units of EmPmR (inside the code, + within coupling interface)
890      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
891      Affects results @ truncation level (cg2d match) and update output of
892       experiments: lab_sea(6), global_ocean.90x40x15(10),
893      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
894      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
895      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
896      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
897    
898    checkpoint59h
899    o pkg/exf:
900      - improve vectorization by moving if-statement out of loops in
901        exf_mapfields, exf_radiation
902      - exf_bulkformulae.F: introduce 2D fields and vectorize code
903    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
904    o testreport:
905      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
906        monitor & update offline_exf_seaice exp. output.
907      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
908    o pkg/seaice:
909      - bug fix in the evp solver: boundary conditions were affected be
910        masking of zMax/zMin (changes results)
911      - minor bug fix in boundary conditions in seaice_calc_strainrates
912        (changes results for no_slip)
913      - seaice_lsr.F: make interpolation of eta dependent on boundaries
914      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
915      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
916        stress formulation and no-slip boundary conditions
917    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
918      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
919    o pkg/seaice: a first HSALT time stepping equation has been checked in
920    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
921      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
922      without requiring DO-IF statements
923    o pkg/thsice:
924      use continuous power-law function for partition of energy between lateral
925      melting/freezing and thinning/thickening ; old code using step function
926      still available with #undef THSICE_FRACEN_POWERLAW
927      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
928    o testreport: change AD testing : check against results/output_adm.txt
929      using same scripts as for forward test.
930    
931    checkpoint59g
932    o adjoint testing: in preparation for changing testreport:
933      - output format: cost and grad written on separated lines
934      - ad output results in directory "results" (instead of "results_ad")
935    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
936    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
937    o pkg/ecco: allow user defined cost function contributions
938    o testreport:
939      Allow to choose (per experiment) the list of tested output variables
940       and the main variable (used to issue a pass/FAIL ) ;
941      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
942      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
943      Also modify printing of summary:
944       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
945       b) echo the list of tested variables in the individual summary.txt of
946          each experiment.
947    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
948      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
949      (but still depend on the tile decompostion of the domain).
950    o pkg/seaice: change a discretization detail to make the B-grid code
951      "more symmetric". This change is likely to remove all "ridges/leads" that
952      where quasi-aligned with the grid in B-grid solutions. It may also be
953      the solution to the stress coupling issues with the B-grid.
954    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
955      remove .cvsignore from input dir. (since testreport no longer run here).
956    o pkg/thsice:
957     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
958     - fix reshaping of sea-ice just after advection:
959       melt all the ice only if ice-volume is too small.
960     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
961       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
962     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
963    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
964      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
965    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
966      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
967      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
968      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
969      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
970      -> update output.txt
971    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
972     this affects truncation error: -> update output.txt of exp:
973      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
974      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
975    
976    checkpoint59f
977    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
978    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
979      a bounded range (in forward mode)
980    o pkg/ecco, ctrl, autodiff and mom_common:
981     internal parameter controls, completements of implementations
982    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
983    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
984      (not seem any difference in testing results).
985    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
986       at face corners.
987    o pkg/generic_advdiff:
988     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
989      loop range indices for computing vertical advection tendency
990      and do the calculation in the interior only (no overlap) ;
991      for now, only implemented for SOM advection (to save CPU time).
992     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
993    o exch2 adjoint
994      First set of changes:
995      - add exch2 hand-written adjoint templates
996      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
997        This will require cleanup in pkg/autodiff/*.F
998        (changed routines currently kept separate in verif. code/)
999      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1000        that used to hide exch2 or cubed-sphere specific code
1001        (commented via 'cph-exch2')
1002    o pkg/seaice
1003      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1004    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1005       output of global_ocean.cs32x15.thsice .
1006    
1007    checkpoint59e
1008    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1009      for B-grid vector (not yet tested) and C-grid vector (<- only used
1010      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1011    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1012      (#ifdef ALLOW_SALT_PLUME)
1013    o gather_2d/scatter_2d: removed halo regions
1014    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1015      scheme and the corresponding test case (under front_relax dir). For now,
1016      only available with Skew-flux form and not yet tested in realistic set-up.
1017      adjoint: store directives updated, but gradient checks deteriorated,
1018      so maybe GM/Redi adjoint is now broken.
1019    o seaice adjoint
1020      * add AREA, HEFF, HSNOW as control variable
1021        (should not change lab_sea results)
1022      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1023    o pkg/seaice:
1024      * added computation of saltFlux in seaice_growth;
1025        For time being, sea ice salinity is assumed constant
1026        contribution of snow flooding to freshening of sea ice is neglected.
1027        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1028        defaults to 0.0 in order to maintain backward compatibility.
1029        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1030      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1031      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1032        heat content used to melt or grow ice
1033      * commented out cap of HICE: it helps keep ice thinner
1034      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option

1049     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1050     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1051       changes verification/lab_sea
1052     - rearrange implicit part of u-equation in LSR solver to make it easier to
1053       read, understand, and debug. This causes changes at the truncation level.
1054     - fix (serious) bug in the boundary conditions (sign error in the implicit
1055       part) of the LSR solver. Changes all LSR results.
1056     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1057       is initilized with small values - does not change lab_sea results.
1058     - added HsnowFile initialization capability
1059    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1060     initialization of pkg/smooth and application to control vector
