4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adding doc/diags_changes.txt
8    o model/src:
9      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
10       to avoid "_diags" naming if no relation to pkg/diagnostics.
11      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
12       file and only call PLOT_FIELD_XYZ if debugMode=T.
13      remove few PLOT_FIELD_XY calls outside initialisation.
14      remove few unnecessary BARRIER.
15    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
16      of salt_plume package in Southern Ocean
17    o pkg/thsice:
18     - fix hOceMxL in overlap (needed for sea-ice advection);
19       update output of experiment global_ocean.cs32x15.icedyn.
20    o pkg/seaice:
21     - make the (placeholder-)tracer IceAge a little more meaningful
22      by avoiding ridging of age due to convergent ice flow
23     - add diagnostics for surface temperature, atmospheric and oceanic
24       heat flux, and atmospheric and oceanic ice growth
25    
26    checkpoint61p
27    o eesupp (global_max & global_sum):
28     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
29     - remove starting & endding barrier (no longer needed)
30    o pkg/mdsio, writelocal:
31       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
32       (remove the STOP): uses shared buffer IO to store data from all threads
33       and then let master-thread write nThreads tiles.
34    o pkg/mdsio (read/write field):
35     - tiled IO done in 1 piece (all levels at a time);
36     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
37     - multi-threaded: allow to read/write local (non-shared) array
38       (was already working with singleCpuIO ; now works also without);
39       => no longer needs barrier call after reading a file (added inside
40       mds_read/write field).
41     - move barrier calls outside gather/scatter_2d to mds_read/write_field
42    o pkg/obcs/exf
43      - exf_getffieldrec.F: add a few ". _d 0" and
44                            add code to catch the case fldperiod = 0.  
45      - obcs_precribe_read.F: change if statements so that they match
46                              the variable type (_RL)
47      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
48        exf_iprec) as part of namelist EXF_NML_01
49    o pkg/mdsio:
50      - read/write tiled (local) files: read/write 1-level tile chunk at a time
51        (instead of segment of length sNx); expected to speed up tiled IO.
52    o pkg/exch2:
53      - take buffer copy from/to array out of S/R exch2_send/recv into new
54        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
55        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
56      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
57      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
58        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
59        including Topology header file (and common blocks).
60      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
61        remove 2nd exch call in exch2_s3d_rx (no longer needed).
62      - document S/R arg. list (+ update some comments)
63    o pkg/seaice:
64      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
65        temperature and humidity over sea ice based on climatological values.
66      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
67        of LSR (this change is expected to change the results slightly because now
68        it uses slightly difference moduli from the second last LSR solution, but
69        that is more consistent with the stress computations; this part of the code
70        is not tested in the verification experiments)
71      - fix diagnostics for flux of ice in case of B-grid
72      - turn strain rates eij and press into global fields within global
73        common block in SEAICE.h for more straighforward diagnostics
74      - fix diagnostics for principal stress components, press, zeta, eta
75        to give something meaning full
76    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
77      new output (all 4 tests) using default rotationPeriod.
78    o pkg KPP:
79      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
80      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
81        and normal grid from 1 to Nr)
82    o Fix computations of L4rdt in mom_calc_visc.F
83    o eesupp:
84      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
85      should be called before a "stop" if we know that all process are going
86      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
87    
88    checkpoint61o
89    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
90    o model/src/ini_curvilinear_grid.F:
91       compute angleSin/CosC when they are not read from a file
92    o pkg/seaice:
93       add pseudo time stepping for LSOR
94    o pkg/exch2:
95       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
96    o pkg/seaice:
97       Adding separate sea ice albedo, drag coefficients, and HO in Southern
98       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
99    o SingleCpuIO:
100       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
101    o pkg/seaice:
102       put exchanged variable in (local) common block for MPI+Multi-Threads
103       to work (necessary with exch1, and for now with exch2 too).
104    o verification: to get more experiments tested with mpi, mth and mpi+mth,
105      change tiling of:
106       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
107       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
108      update output of exp:
109       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
110       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
111      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
112                       (note: output.txt generated on faulks using only 1 tile)
113    o eesupp & mdsio (SingleCpuIO):
114     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
115       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
116       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
117     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
118     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
119       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
120    o pkg/exch2:
121     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
122       read parameter file "data.exch2" if it exists; otherwise try default regular
123       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
124     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
125       with new code (not to be used, just as a backup solution).
126     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
127       in utils/exch2/input.
128    
129    checkpoint61n
130    o eesupp & mdsio (SingleCpuIO):
131      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
132        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
133        receive real*4 array (instead of real*8) to read/write 32.bit files.
134        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
135         and remove new mapping S/R)
136    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
137      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
138        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
139        when using exch2. Add S/R to map global io-buffer to global model array.
140      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
141    
142    checkpoint61m
143    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
144      and add 3 other S/R for other types (R4,R8,RS).
145      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
146    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
147     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
148     - reduce number of macro definitions (keep only those which are used);
149       can always call directly the corrresponding S/R if needed.
150     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
151       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
152     Fixed wrong type of arg in:
153       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
154       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
155     To fix: global_sum of var in common block is wrong (multi-threaded) in:
156       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
157     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
158    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
159      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
160    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
161    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
162      edges are closed (zero depth); might happen with "blank tiles";
163      for now, disabled if using OBCS.
164    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
165      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
166    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
167      to reduce length of 1.D array print in STDOUT.
168    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
169      + use 48 tiles (16x8): this will allow to test "blank tiles".
170    o start to test MPI + multi-threaded (change testreport to skip tests
171      where number of tiles do not match).
172    o genmake2: add option "-omp" to turn on Open-MP ;
173      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
174    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
175      and keep the original tile numbering. Note: compatible with old
176      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
177    
178    checkpoint61l
179    o Overlaps had been forgotten in calculating ijk keys : fixed
180    o fix cyrus makedepend for gcc 4.4
181    o experiment fizhi-cs-aqualev20:
182      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
183      and generate new output. Note: new output is much closer to the old
184      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
185      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
186    o pkg/fizhi:
187     - change to avoid indices going deliberately over array-bounds
188     - remove unnecessary MPI stuff
189     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
190     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
191       does not go over array-bounds and therefore returns reliable output.
192     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
193       this S/R has 4 output arguments, which are used inside "get_alarm";
194       when it is called with the same variable "ndum" in place of several
195       output arguments, this produces weird side effect inside "get_alarm"
196      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
197       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
198       address) and produces error.
199    o tools/gemake2: (March 27-29 2009)
200      with option "-mpi": link *_mpi files from "MODS" dir (this is what
201      testreport does).
202    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
203    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
204       update lab_sea.lsr & lab_sea.salt_plume results
205    o pkg/seaice:
206      Major overhaul of the LSOR solver: change discretization from original
207      finite differences to finite volume. The old routine is still in the
208      file seaice_lsr.F and can be turned on with the CPP-flag
209      SEAICE_OLD_AND_BAD_DISCRETIZATION
210      Along with this change, the discretization of the strain rates is changed.
211      The same flag turns on the old discretization in seaice_calc_strainrates.F
212      All verification experiments with seaice are affected (except for
213      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
214      results by setting the above flag.
215      Further changes involve changes in defaults:
216      - ALLOW_FLOODING is defined and turned on by default
217      - SEAICEadvSnow = .true. is now the default
218      - SEAICEadvSalt = .true. is now the default
219      - SEAICEadvAge  = .true. is now the default
220      - SEAICE_clipVelocities  = .false. is now the default
221                                         (as per J. Zhang's recommendation)
222      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
223        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
224      - seaice_growth: replace computation of UG by a simple copy from wspeed
225    
226    checkpoint61k
227    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
228      seaice_lsr: fixed a few metric terms,
229                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
230                  add more debugging diagnostics
231      seaice_evp: removed superfluous many metric terms of FV discretization
232                  of stress divergence
233                  affects lab_sea, lab_sea.hb87
234      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
235                  of stress divergence for non-evp solver
236                  (this part is not tested anywhere)
237      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
238                  they were effectively only half slip
239                  affects lab_sea.hb87
240      updated all relevant verification experiments (except lab_sea//output_adm.txt
241        which was left over, but fails at level 7 & 6)
242    
243    checkpoint61j
244    o pkg/seaice: turn a few hard wired parameters into run time parameters
245    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
246      time in seconds as promised by the usints in seaice_monitor and exf_monitor
247    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
248      that are not cubed-sphere grids
249    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
250    o pkg/ctrl:
251      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
252    o non-hydrostatic (calc_gw.F):
253      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
254      update output of exp. global_ocean.cs32x15.viscA4
255    o remove backward compatibility for thetaMin,phiMin
256      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
257    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
258      interpolated wind field not only for curvilineargrid=.true., but also
259      for a rotated grid (rotateGrid=.true.)
260    o pkg/exf: add capability to bypass interpolation for runoff
261      by setting yet another CPP-flag
262    o eesupp/src, B-grid exchange:
263      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
264    o autodiff
265      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
266      allows to switch to single-prec common blocks;
267      corresponding switch occurs in tamc.h, integer isbyte
268      TAF store directivs "byte" and "kind" seem equivalent;
269      Most tamc.h have been updated correspondingly.
270    
271    checkpoint61i
272    o autodiff:
273      fix autodiff_sore/_restore indices for obcs
274      (spotted by I. Hoteit, M. Mazloff)
275    o pkg/autodiff, pkg/ctrl:
276      Add flag to reduce all tapelev I/O to single-prec.
277      In data.ctrl set
278        doSinglePrecTapelev = .TRUE.
279    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
280      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
281    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
282      real fresh water flux (not yet)
283    o pkg/mdsio & rw:
284     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
285     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
286    o pkg/flt:
287     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
288       init_fixed & ini_varia.
289     - clean-up & simplify linear interpolation S/R:
290       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
291     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
292     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
293     - add vert. coordinate & horiz. indices to output files.
294     - change vertical position in initial condition, from index to depth [m].
295     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
296       (easier to get to a curvilinear grid) ; delX,delY no longer used.
297    o pkg/ggl90: a few modifications:
298     - fix bottom boundary condition, and interpolation of KappaE
299       near top and bottom
300     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
301     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
302     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
303    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
304      (maintain temporary backward compatibility, until next checkpoint)
305    
306    checkpoint61h
307    o pkg/diagnostics with "periodic averaging diagnostics":
308      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
309    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
310    o pkg/obcs: fix loop ranges for balancing code
311    o pkg/flt:
312     - improve criteria for finding which tile owns a float.
313     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
314    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
315      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
316      with ocean biogeo)
317    o pkg/flt:
318     - do some cleaning and fix the restart ;
319     - add output.txt in flt_example/results to get this pkg tested.
320    o genmake2: add an EXTENDED_SRC option and flag.
321       for now, cannot be turned on on command line (only through genmake_local)
322    o pkg/mdsio: read/write vector:
323     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
324     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
325       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
326     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
327      (drop to 4 digits matching for grad). But this test does not look very
328      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
329    
330    checkpoint61g
331    o pkg/flt:
332      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
333       + make OPTIONS file more standard.
334      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
335      - fix _BYTESWAPIO CPP-Flag
336      - standard reading of file-parameter "data.flt"
337      - fix argument list of S/R FLT_RESTART
