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