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