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