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

367    o pkg/obcs: fix loop ranges for balancing code
368    o pkg/flt:
369     - improve criteria for finding which tile owns a float.
370     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
371    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
372      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
373      with ocean biogeo)
374    o pkg/flt:
375     - do some cleaning and fix the restart ;
376     - add output.txt in flt_example/results to get this pkg tested.
377    o genmake2: add an EXTENDED_SRC option and flag.
378       for now, cannot be turned on on command line (only through genmake_local)
379    o pkg/mdsio: read/write vector:
380     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
381     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
382       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
383     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
384      (drop to 4 digits matching for grad). But this test does not look very
385      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
386    
387    checkpoint61g
388    o pkg/flt:
389      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
390       + make OPTIONS file more standard.
391      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
392      - fix _BYTESWAPIO CPP-Flag
393      - standard reading of file-parameter "data.flt"
394      - fix argument list of S/R FLT_RESTART
395      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
396    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
397    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
398      a still unfixed compiler/optimization bug
399    
400    checkpoint61f
401    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
402      update results of global_ocean.cs32x15.icedyn test.
403    o move getcon.F from model/src to pkg/fizhi.
404    o pkg/exf: add parameter for extrapolation of temp up to the surface
405       and option to prevent negative evap (in bulk_largeyeager04 only).
406    o Prather Advection scheme: fix tracer conservation for divergent flow
407      (e.g., when using NonLin Free-Surface).
408    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
409    o gmredi (Visbeck-variable-K):
410     - add more parameters to Visbeck-variable-K.
411     - use a 5 points average for dSigmaR in Visbeck-K calculation
412       (more "homogenous": same stencil and same weights as in dSigmaH)
413     - update output of ideal_2D_oce experiment.
414    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
415      (#undef REAL4_IS_SLOW)
416     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
417       coordinate variable
418     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
419       (surface forcing fields), removes some of the functionality
420     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
421     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
422       probably not all: copy _RS surface flux fields to RL field before
423       calling DIAGNOSTICS_FILL
424     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
425       real*4 (CALL EXCH_*_RS) versions.
426     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
427       (generate new output).
428    
429    checkpoint61e
430    o gmredi (Visbeck-variable-K):
431      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
432      - change computation of Visbeck-K where Slope > Smax :        
433        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
434        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
435    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
436      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
437    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
438    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
439      does not become too large (to avoid precision problems in implicit-diffusion
440      solver); update ideal_2D_oce output.
441    o pkg ggl90:
442      - in ggl90_cal.F: compute only one set of visc/diff, used to
443        step forward TKE/T/S/momentum
444      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
445        have Prandlt =1)
446    o gmredi (fm07):
447      - add lower limit on Transition layer thickness + lower limit on 1/lambda
448      - allow to set few more params from data.gmredi
449    o pkg ggl90:
450          - add missing sqrt(2) factor in computation of mixing length
451            scale in ggl90_calc.F
452            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
453    
454    checkpoint61d
455    o adjoint modifs
456      - adapt to new field rhoInSitu
457      - allow to revert from StoreDynVars2D, StoreDynVars3D
458        to individual fields
459        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
460    o store 3-D (in-situ) density in commom block (DYNVARS.h)
461     - save 1 rho computation.
462     - no longer modify T & S inland when using down_slope pkg.
463    o gad_som : allow to switch to SOM advection for T & S without corresponding
464      pickup files (using new S/R: MDS_CHECK4FILE).
465    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
466      (for useSingleCpuIO to work in multi-threaded)
467    o pkg/shelfice:
468     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
469       with SHELFICEtopoFile in data.shelfice
470     - move code for reading ice shelf topography and modifying hFacC into separate
471       subroutines of the shelfice package
472     - separate initialisation of "fixed" and "variable" variables
473     - kTopC is not (yet) replaced by kSurfC, although this is possible
474    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
475    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
476      and rename:
477      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
478      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
479    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
480    
481    checkpoint61c
482    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
483      to add mass source/sink of fluid in the interior (3-D generalisation
484      of oceanic real-fresh water flux).
485    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
486    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
487    o new pkg: down_slope
488      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
489      - presently, modify T & S inland (dwnslp_calc_rho.F).
490        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
491      - implementation for ocean in P-coords not tested.
492      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
493    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
494      (to facilitate conversion of oceanic pkg to p-coordinate).
495    o change FIND_RHO to FIND_RHO_2D :
496      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
497    o new pkg: cheapaml
498    
499    checkpoint61b
500    o exch2:
501      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
502      - no longer depend on the order sequence (N,S,E,W).
503      - 3rd exchange no longer needed (tested with 24 tiles).
504      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
505      - exch_UV_A-grid readily available (but not yet tested).
506      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
507      (both are no longer needed) in exch_uv: no effect in forward run; but
508       get truncation error differences with adjoint exch.
509    o exch2:
510     - change index-bounds storage (moved from target to local tile,
511       more intuitive this way) ; rename/remove some variables.
512     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
513    
514    checkpoint61a
515    o exch2/matlab-topology-generator:
516      fix bug in index bounds for N-S internal exchange (hard to tell if this
517      had any effect on the solution).
518    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
519      is exceeded
520    o testreport: modify syntax of awk, so that it works also with
521      awk, and not only with nawk and gawk
522    
523    checkpoint61
524    o autodiff
525      Change default for TAF usage by removing argument '-nonew_arg'
526      This changes TAF subroutine argument list (ordering of active var.)
527      Omission of this flag leads to incompatibility w.r.t. TAMC
528      To restore TAMC-compatibility, need following modifs:
529      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
530      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
531      Tested TAF version is 1.9.22
532      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
533    
534    checkpoint60
535    --->>> This is the last checkpoint for which generating the adjoint
536    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
537    --->>> by default.
538    --->>> Future checkpoints will ommit this flag by default.
539    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
540    o pkg/grdchk: Add gradient check to etan0 perturbations.
541    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
542    o pkg/autodiff: more flexibility in zeroadj.
543      model/src: modifying do_oceanic_phys.F accordingly.
544    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
545    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
546      special setup of gmredi for which the adjoint is stable
547      enough for parameter optimization.
548    o bridging the gap between eddy stress and GM.
549      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
550          along with a change in CPP option (now ALLOW_EDDYPSI).
551      -> when using GM w/ GM_AdvForm:
552          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
553          is applied either in the tracer Eq. or in momentum Eq.
554          depending on data.gmredi (intro. GM_InMomAsStress).
555      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
556      The key modifications are in model/src/taueddy_external_forcing.F
557      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
558    
559    checkpoint59r
560    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
561      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
562      fix option to read coriolis(@ cell-corner) from files with CS-grid.
563    o pkg/mnc: add some attributes to standard 1D-coordinate variables
564    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
565      mass points, when using mnc for output
566      - add runtime parameter (missing_value, missing_value_int) to override
567        default (which is the value of getcon('UNDEF'))
568    o pkg/mnc: prepare mnc for the actual use of missing values with the
569      diagnostics package: small fix in mnc_cw_readwrite.template and more
570      initialisation of never used fields
571      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
572      versions
573    o pkg/thsice/thsice_ini_vars.F added default initial values so that
574      thermodynamics sea ice solver does not blow up when some initial fields
575      are missing.
576    o move from external_forcing_surf.F to ini_forcing.F
577      the p-coord. hack consisting in using pLoad to set phi0surf ;
578      update output of tutorial_global_oce_in_p (affected @ truncation level).
579    o Freshen up a bit hs94.1x64x5, notably:
580      remove rotationPeriod and tRef=5*0. (adjoint only), and add
581      exactConserv=.TRUE.
582    o pkg/generic_advdiff:
583      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
584      applies to files where Temperature & Salinity 2nd Order moments are used.
585    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
586      this uses a dynamically allocated internal state data structure
587      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
588      and requires a fortran 90 compiler
589    
590    checkpoint59q
591    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
592       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
593    o Refresh tutorial_global_oce_biogeo, notably:
594      - change bathymetry (put back seamounts in ACC, use hFacs)
595      - change EOS (POLY3 --> JMD95Z)
596      - use Bryan-Lewis vertical diffusivity
597      - use multidimensional advection
598      - remove old virtual virtual in dic pkg, now done through ptracer pkg
599      - change a couple of parameters in dic pkg
600    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
601    o pkg/obcs: change default to OBCSfixTopo = .true.,
602      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
603      - replace "debugMode" with "debugLevel .GE. debLevB"
604    o implementation of TAF directives for gchem,cfc,dic
605    o remove "exp5" (replaced by tutorial_deep_convection).
606    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
607      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
608      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
609      --> changes results in exp4, seaice_obcs
610    o tutorial_deep_convection :
611      update the set-up and increase resolution and domain size ; start
612      from pseudo initial conditions = output at t=120mn in order to see
613      something happening when running testreport.
614    o pkg/seaice: add os7mp as an advection scheme
615                  add check for advection schemes
616                  add a flag for restoring T and S underneath sea ice
617    o pkg/my82: add netcdf-support and diagnostics
618    o thsice pkg:
619      - Now hsMax limits snow height by turning it into ice following
620        flooding scheme (and now conserving energy)
621      - Slight rewriting of the formula in thsice_calc_thick.F
622      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
623      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
624    
625    checkpoint59p
626    o gchem / dic / cfc :
627      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
628      - add new parameter files: "data.dic" & "data.cfc" ;
629      - various re-arrangement in initialisation & header file ;
630      - fix tutorial_global_oce_biogeo for multi-threaded test.
631    o pkg/dic: test for "pickup_dic" file when restarting ;
632      if no pickup-file, can restart with a re-initialised pH (same as it did
633      before) providing pickupStrictlyMatch is set to False.
634    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
635      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
636    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
637      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
638    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
639     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
640       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
641    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
642       scheme to use for vorticty-term ;
643     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
644       (with default selectVortScheme, return to original discretisation)
645     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
646    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
647    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
648      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
649      also fix diagnostics VISCAHW & VISCA4W.
650    
651    checkpoint59o
652    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
653    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
654      move a few statemens out the main loop into separate loops
655    o pkg/shelfice:
656      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
657        (kg/m^2/s), does not break tests, because in verification/isomip,
658        rhoConstFresh=rhoConst (by accident)
659      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
660      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
661        new file model/src/seawater.F, so that they are available for all pkgs.
662      - convert potential temperature into in-situ temperature. This changes the
663        isomip tests => update tests
664    o add a flag writePickupAtEnd (default=true) to be able to suppress
665      writing a pickup at the last timestep
666    o tools/mpack-1.6 :
667      - disable automake (not working) and autoconf (not needed).
668      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
669        also cleaner with much less compilation warnings.
670    o pkg/profiles:
671      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
672      (for "less than 32 characters name" compiler requirement)
673    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
674      conditions that have a different sampling frequency than S/T/U/V obcs
675    o pkg/diagnostics (stats-diags):
676      - fix global Min/Max in case 1 processor get only empty tiles
677    o genmake2: replace (4 times)
678         make genmake_tc_1.o >> genmake_warnings 2>&1
679      with
680         COMM="$CC $CFLAGS -c genmake_tc_1.c"
681         echo $COMM >> genmake_warnings
682         $COMM >> genmake_warnings 2>&1
683      to make genmake2 always see the value of CC as specified in the optfile.
684    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
685      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
686      - modify verification advect_cs test to test SOM-advection on CS-grid.
687    o pkg/ctrl:
688      - Rewrite of ctrl_map_ini_ecco.F,
689        introducing a generic routine (ctrl_map_ini_gen.F).
690      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
691    
692    checkpoint59n
693    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
694      number in dedicate array "hdiag":
695      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
696        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
697      - many small changes (integer format) for large number of diagnostics
698      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
699        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
700    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
701      usingSphericalGrid, this allows to define the rotated grid coordinates
702      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
703      geographical coordinates according to the inverse of the rotation defined
704      by the Euler angles, so that Coriolis parameter and online-interpolation by
705      exf works with the geographical coordinates on XC/YC/XG/YG.
706      Naturally, this feature does not work with all packages, so some
707      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
708      profiles), because there the coordinates are assumed to be regular
709      spherical grid coordinates.
710    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
711      - introduce isopycnal diffusion coefficient control.
712    o tools/adjoint_options:
713      - additional control vector components.
714    o pkg/mnc: have mnc create marginally meaning full coordinate variables
715      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
716    o pkg/mypackage:
717      - add example of read/write pickup for state-var ;
718      - add entry points to the main code for state-vars diags & write-pickup.
719    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
720      transitions for useExfYearlyFields
721      - add new subroutine that determines the file to read from for
722        use*YearlyFields = .TRUE. and .FALSE.
723      - add a verification experiment to global_with_exf that tests
724        useExfYearlyFields with USE_EXF_INTERPOLATION defined
725    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
726      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
727      subroutines (which could be generated from a template, because they are
728      almost identical), for now they are included in obcs_prescribe_read.F for
729      simplicity
730    o pkg/exf:
731      - add a little more diagnostic to exf_interp_read (in analogy to
732        mds_read_field, can be turned off with debugLevel < debugLevA=1)
733      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
734        ugly but fast by unrolling short inner loops, inserting a unroll=8
735        directive in routine lagran, and splitting a loop and making do while the
736        outermost loop (the latter requires the intoduction of index arrays)
737    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
738    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
739      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
740    o verification/seaice_obcs: updated for restart test and latest options
741    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
742      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
743      for now this is only available for the C-grid code and also within
744      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
745    
746    checkpoint59m
747    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
748      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
749    o gad_som : fix flux output (& diagnostics) to have same units as other  
750      advection scheme fluxes (was previously multiplied by deltaT).  
751    o added verification/seaice_obcs both to test seaice open boundaries
752      and to provide an example matlab scrpt for generating them
753    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
754    o pkg/salt_plume: clean up salt_plume_frac.F to
755      remove redundancy in PlumeMethod 1 and 4
756    o pkg/kpp: added saltplume diagnostics
757    o pkg/obcs and pkg/seaice:
758      - do not set uice and vice to zero when OB*icefile are unspecified
759      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
760      - moved seaice tracer obcs after call to seaice_growth
761    o pkg/salt_plume: added various options for salt plume depth
762      criterion and for vertical distribution of the salt
763    
764    checkpoint59l
765    o pkg/ptracers: new version of ptracers pickup:
766      read meta file and write only fields which are needed to restart.
767      ( same logic as main pickup file ; also using pickupStrictlyMatch )
768    o pkg/seaice:
769      - add timescale for melting due to warm mixed layer as a means of
770        setting SEAICE_availHeatFrac more conveniently
771      - add a CPP-flag/runtime parameter check for flooding algorithm
772      - reformulated availHeat in seaice_growth.F to be independent of AREA
773    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
774      unit changes
775    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
776    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
777      SX vector computer.
778    o pkg/seaice:
779      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
780        seaice forcing fields can now be read only through pkg/exf
781      - removed some unused halos
782    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
783    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
784      or U/VICE from U/VWIND before computing U/VSTRESS
785    
786    checkpoint59k
787    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
788      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
789    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
790      all experiments pass when compile with un-initialised var. checking option.
791    o added pkg/salt_plume
792    o script to test restart (for now, in MITgcm_contrib/jmc_script)
793    o pkg/seaice: new read/write pickup version.
794      read meta file and write only fields which are needed to restart.
795      ( same logic as main pickup file ; also using pickupStrictlyMatch )
796    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
797    o lab_sea.hb87: modify the domain & update output.hb87.txt :
798      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
799      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
800      process. Fixed here by closing the domain at the Northern boundary.
801    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
802    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
803      a set of consecutive levels in/from a 3-D array.
804    o pkg/ptracers:
805      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
806      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
807    
808    checkpoint59j
809    o in pkgs: dic, obcs, offline, rbcs:
810      standard way to compute coeff. for time interpolation between 2 time reccords
811      which retains full precision (& make results less dependent on compiler).
812      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
813    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
814      packages instead of reading ice cover and wind speed separately
815    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
816     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
817      to allow to compile customized code before the update)
818    o cleaning-up:
819      - fix CPP instruction syntax in pkg/obcs
820      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
821        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
822      - fix some threads issue in IO parts.
823    o pkg/dic:
824      - add tons of "_d 0" (--> much better testreports !)
825       and then update outputs of tutorial_global_oce_biogeo
826    o pkg/mom_fluxform:
827      add a special version of momentum advection intended to conserve momentum
828      next to a bathymetry step or a coastline edge. (default = off = #undef)
829    o new read/write pickup version:
830      - for now, only implemented for main (mdsio) pickup file.
831      - write out only what is needed to restart; merge pickup_nh , pickup_ph
832        and main pickup together.
833      - read meta file; read only what is needed to restart; stop if a field
834        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
835        if it make sense (even if the restart is not perfect).
836      - if no meta file, assume that pickup to read corresponds exactly to
837        a pickup that would currently be written.
838      - read pickup written in the old format (until checkpoint59i) if it
839        recognizes an old meta file (no field-list).
840      - add a meta file in exp. which starts from a pickup: 2 cases:
841        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
842         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
843        b) a meta file describing the content of the associated pickup file
844         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
845    o pkg/mdsio & pkg/rw:
846      - new routine to read a meta file ; new set of routine to read
847        Multiple-fields file (with meta file).
848    o added open boundary conditions capability for seaice
849        HSNOW, HSALT, UICE, and VICE
850    
851    checkpoint59i
852    o adjoint:
853      * fix multiDimAdvection adjoint
854        (partial recomputation problem by TAF for fVerT(:,:,kDown)
855        and comlev1 size definition (maxpass vs. max. number of tracers)
856      * verification/global_ocean.90x45x15 adjoint now tests
857        NLFS and multiDimAdvection using DST3 (=30)
858      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
859    o pkg/kpp: add "_d 0" to real constant (if missing);
860      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
861      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
862    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
863      for internal parameters related to restart process (formerly from PARAMS.h)
864      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
865    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
866      as argument. (only atm2d & obcs write_pickup have not yet been updated)
867    o pkg/monitor:
868      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
869      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
870      - account for deep Atmosphere factor and density factor (anelastic)
871    o added open boundary conditions capability for seaice HEFF and AREA
872    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
873      thermodynamics
874      - requires a little reorganization, which affects the testreport results
875        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
876        so that now the conservative form is tested
877      - add a few comments
878    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
879    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
880    o add new diagnostics to seaice: advective, diffusive fluxes (only for
881      multidim-advection, for scheme 2 they are not filled) and transports,
882      thermodynamic growth rates
883    o change units of EmPmR (inside the code, + within coupling interface)
884      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
885      Affects results @ truncation level (cg2d match) and update output of
886       experiments: lab_sea(6), global_ocean.90x40x15(10),
887      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
888      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
889      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
890      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
891    
892    checkpoint59h
893    o pkg/exf:
894      - improve vectorization by moving if-statement out of loops in
895        exf_mapfields, exf_radiation
896      - exf_bulkformulae.F: introduce 2D fields and vectorize code
897    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
898    o testreport:
899      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
900        monitor & update offline_exf_seaice exp. output.
901      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
902    o pkg/seaice:
903      - bug fix in the evp solver: boundary conditions were affected be
904        masking of zMax/zMin (changes results)
905      - minor bug fix in boundary conditions in seaice_calc_strainrates
906        (changes results for no_slip)
907      - seaice_lsr.F: make interpolation of eta dependent on boundaries
908      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
909      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
910        stress formulation and no-slip boundary conditions
911    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
912      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
913    o pkg/seaice: a first HSALT time stepping equation has been checked in
914    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
915      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
916      without requiring DO-IF statements
917    o pkg/thsice:
918      use continuous power-law function for partition of energy between lateral
919      melting/freezing and thinning/thickening ; old code using step function
920      still available with #undef THSICE_FRACEN_POWERLAW
921      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
922    o testreport: change AD testing : check against results/output_adm.txt
923      using same scripts as for forward test.
924    
925    checkpoint59g
926    o adjoint testing: in preparation for changing testreport:
927      - output format: cost and grad written on separated lines
928      - ad output results in directory "results" (instead of "results_ad")
929    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
930    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
931    o pkg/ecco: allow user defined cost function contributions
932    o testreport:
933      Allow to choose (per experiment) the list of tested output variables
934       and the main variable (used to issue a pass/FAIL ) ;
935      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
936      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
937      Also modify printing of summary:
938       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
939       b) echo the list of tested variables in the individual summary.txt of
940          each experiment.
941    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
942      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
943      (but still depend on the tile decompostion of the domain).
944    o pkg/seaice: change a discretization detail to make the B-grid code
945      "more symmetric". This change is likely to remove all "ridges/leads" that
946      where quasi-aligned with the grid in B-grid solutions. It may also be
947      the solution to the stress coupling issues with the B-grid.
948    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
949      remove .cvsignore from input dir. (since testreport no longer run here).
950    o pkg/thsice:
951     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
952     - fix reshaping of sea-ice just after advection:
953       melt all the ice only if ice-volume is too small.
954     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
955       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
956     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
957    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
958      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
959    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
960      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
961      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
962      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
963      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
964      -> update output.txt
965    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
966     this affects truncation error: -> update output.txt of exp:
967      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
968      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
969    
970    checkpoint59f
971    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
972    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
973      a bounded range (in forward mode)
974    o pkg/ecco, ctrl, autodiff and mom_common:
975     internal parameter controls, completements of implementations
976    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
977    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
978      (not seem any difference in testing results).
979    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
980       at face corners.
981    o pkg/generic_advdiff:
982     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
983      loop range indices for computing vertical advection tendency
984      and do the calculation in the interior only (no overlap) ;
985      for now, only implemented for SOM advection (to save CPU time).
986     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
987    o exch2 adjoint
988      First set of changes:
989      - add exch2 hand-written adjoint templates
990      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
991        This will require cleanup in pkg/autodiff/*.F
992        (changed routines currently kept separate in verif. code/)
993      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
994        that used to hide exch2 or cubed-sphere specific code
995        (commented via 'cph-exch2')
996    o pkg/seaice
997      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
998    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
999       output of global_ocean.cs32x15.thsice .
1000    
1001    checkpoint59e
1002    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1003      for B-grid vector (not yet tested) and C-grid vector (<- only used
1004      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1005    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1006      (#ifdef ALLOW_SALT_PLUME)
1007    o gather_2d/scatter_2d: removed halo regions
1008    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1009      scheme and the corresponding test case (under front_relax dir). For now,
1010      only available with Skew-flux form and not yet tested in realistic set-up.
1011      adjoint: store directives updated, but gradient checks deteriorated,
1012      so maybe GM/Redi adjoint is now broken.
1013    o seaice adjoint
1014      * add AREA, HEFF, HSNOW as control variable
1015        (should not change lab_sea results)
1016      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1017    o pkg/seaice:
1018      * added computation of saltFlux in seaice_growth;
1019        For time being, sea ice salinity is assumed constant
1020        contribution of snow flooding to freshening of sea ice is neglected.
1021        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1022        defaults to 0.0 in order to maintain backward compatibility.
1023        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1024      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1025      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1026        heat content used to melt or grow ice
1027      * commented out cap of HICE: it helps keep ice thinner
1028      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1029      * applied OBCS T/S mask to HEFFM sea ice mask
1030    
1031    checkpoint59d
1032    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1033     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1034     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1035    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1036     and change default value of parameter "GM_Small_Number";
1037     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1038       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1039       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1040    o pkg/ecco: cost function when applying pkg/smooth to controls
1041    o pkg/ctrl: add forcingPrecond run time parameter
1042    o pkg/seaice:
1043     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1044     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1045       changes verification/lab_sea
1046     - rearrange implicit part of u-equation in LSR solver to make it easier to
1047       read, understand, and debug. This causes changes at the truncation level.
1048     - fix (serious) bug in the boundary conditions (sign error in the implicit
1049       part) of the LSR solver. Changes all LSR results.
1050     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1051       is initilized with small values - does not change lab_sea results.
1052     - added HsnowFile initialization capability
1053    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1054     initialization of pkg/smooth and application to control vector
1055    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1056    o dependencies: pkg/profiles requires pkg/cal
1057    o pkg/profiles:
1058     - added option ALLOW_PROFILES_GENERICGRID
1059         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1060         that interpolation information (grid points and coefficients) is provided
1061         within the netcdf input files.
1062         -> sample matlab scripts can be found in MITgcm_contrib/gael
1063         that allow you to prepare netcdf input files.
1064     - also modified: cleaner include statements, cleaner error print statements,
1065       cleaner stops when error, and more tests of the netcdf input files consistency.
1066    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1067    o pkg/seaice:
1068     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1069       requires a new routine: seaice_diagnostics_fill.F
1070     - make sure that seaice does not move if not forced (pressure replacement
1071       method, Hibler and Ip, 1995), changes results
1072     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1073     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1074       It is turned off by default (=-1.), because it changes the results.
1075     - make it possible to read AREA from a file, too.
1076    
1077    checkpoint59c
1078    o add S/R and diagnostics for oceanic mixed-layer depth
1079    o move GMRedi call after all vertical mixing schemes (including KPP)
1080    o pkg/thsice:
1081     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1082      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1083    o pkg/obcs:
1084     - bug fix for balance code
1085    o pkg/seaice:
1086      - allow values of SEAICE_elasticParm > 1
1087      - add new parameter SEAICE_evpTauRelax as an alternative
1088        to SEAICE_elasticParm
1089      - make lsr boundary conditions free slip (by default), changes result
1090      - add code for no slip boundary conditions for lsr
1091      - set minimum of zeta to zero (and not 4e8) (changes results)
1092      - add a cap on AREA after advecting AREA if seaice_growth is not called
1093    o change calculation of Visbeck K:
1094      - no longer depend on tapering scheme; instead, compute slope (limited
1095        by GM_maxSlope). this is equivalent to what was comuted before with
1096        clipping or linear tappering.
1097      - fix vertical averaging (wrong by 1/2 level)
1098      - leave the old version (but will not be maintained) within
1099        #ifdef OLD_VISBECK_CALC / #endif
1100      - update output of exp. ideal_2D_oce
1101    o change error catch in calc_r_star to improve vectorization
1102    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1103      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1104    o adjoint:
1105      Re-organized adjoint checkpointing according to Matt Mazloff
1106      (but with modifs/completions/cleanups)
1107      Storing is now bundled into large arrays to optimized I/O
1108      (and second step in cleanup of the_main_loop)
1109    
1110    checkpoint59b
1111    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1112      - export/import (between ocean & coupler) fields needed for ocean DIC.
1113    o pkg/seaice:
1114      - get rid of three more exchanges seaice_calc_viscosities (required
1115        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1116      - bug fix in seaice_ocean_stress (update of lab_sea required)
1117      - reduce loop boundaries to necessary minimum also in seaice_evp
1118      - go back to the old way of computing deltaC/Z as the adjoint likes that
1119        better
1120    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1121      passive tracer to an Age Tracer) + update output.txt
1122    o pkg/exf:
1123      - implement A-grid / C-grid selection for wind-stress input files.
1124      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1125      for now, in exf_bulk_largeyeager04.F only :
1126      - change implementation for case where windspeed + 2. components wind-stress
1127        are read-in. AND use rhoConstFresh to convert evap.
1128    o pkg/seaice:
1129      - use correct EXCH_UV for wind-forcing (on A-grid).
1130      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1131        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1132    o pkg/exf:
1133      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1134      EXF_INTERPOLATION:
1135      - merge global_with_exf/code version of exf_interp_read.F
1136        to the main code ;
1137      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1138        reading the file ; Important: This options needs to be defined to recover
1139        previous code.
1140        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1141      - no longer loose real*8 precision along the way when using exf_iprec=64.
1142  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1143      - change discretisation of evp-solver in order to avoid another exchange
1144        (changes lab_sea) and clean up a little
1145      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1146        help the adjoint (this also changes the results slightly)
1147      - add a few "_d 0" where they had been missing in seaice_evp.F
1148      - cleaning up: remove unused seaice_calc_rhs.F
