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

343    o pkg/diagnostics with "periodic averaging diagnostics":
344      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
345    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
346    o pkg/obcs: fix loop ranges for balancing code
347    o pkg/flt:
348     - improve criteria for finding which tile owns a float.
349     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
350    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
351      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
352      with ocean biogeo)
353    o pkg/flt:
354     - do some cleaning and fix the restart ;
355     - add output.txt in flt_example/results to get this pkg tested.
356    o genmake2: add an EXTENDED_SRC option and flag.
357       for now, cannot be turned on on command line (only through genmake_local)
358    o pkg/mdsio: read/write vector:
359     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
360     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
361       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
362     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
363      (drop to 4 digits matching for grad). But this test does not look very
364      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
365    
366    checkpoint61g
367    o pkg/flt:
368      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
369       + make OPTIONS file more standard.
370      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
371      - fix _BYTESWAPIO CPP-Flag
372      - standard reading of file-parameter "data.flt"
373      - fix argument list of S/R FLT_RESTART
374      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
375  o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell  o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
