4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
8      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
9        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
10      - verification experiment natl_box.longstep
11    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
12      allow different versions of ifort (8 or 9) and different versions
13       of mpi (mpich or mpich2) to be used with the same optfile.
14      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
15       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
16    
17    checkpoint61r
18    o pkg/seaice:
19     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
20      1. introduce fields for time step (N-1)
21      2. do not use levels 2 and 3 anymore (but keep them)
22      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
23         includes changes to pkg/thsice/thsice_get_velocity.F,
24         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
25         pkg/obcs/obcs_apply_uvice.F.
26     - completely remove code for leap-frog time stepping for second order
27       advection
28     - adjusted adjoint accordingly;
29       gradient checks have improved by an order of magnitude!
30    
31    checkpoint61q
32    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
33     - the boundary conditions along open boundaries are unclear, because the
34       associated masks are set to zero and are thus treated as closed when
35       applying the slip-boundary conditions.
36     - move initialisation of grid variables from seaice_init_varia to _fixed
37    o adding doc/diags_changes.txt
38    o model/src:
39      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
40       to avoid "_diags" naming if no relation to pkg/diagnostics.
41      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
42       file and only call PLOT_FIELD_XYZ if debugMode=T.
43      remove few PLOT_FIELD_XY calls outside initialisation.
44      remove few unnecessary BARRIER.
45    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
46      of salt_plume package in Southern Ocean
47    o pkg/thsice:
48     - fix hOceMxL in overlap (needed for sea-ice advection);
49       update output of experiment global_ocean.cs32x15.icedyn.
50    o pkg/seaice:
51     - make the (placeholder-)tracer IceAge a little more meaningful
52      by avoiding ridging of age due to convergent ice flow
53     - add diagnostics for surface temperature, atmospheric and oceanic
54       heat flux, and atmospheric and oceanic ice growth
55    
56    checkpoint61p
57    o eesupp (global_max & global_sum):
58     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
59     - remove starting & endding barrier (no longer needed)
60    o pkg/mdsio, writelocal:
61       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
62       (remove the STOP): uses shared buffer IO to store data from all threads
63       and then let master-thread write nThreads tiles.
64    o pkg/mdsio (read/write field):
65     - tiled IO done in 1 piece (all levels at a time);
66     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
67     - multi-threaded: allow to read/write local (non-shared) array
68       (was already working with singleCpuIO ; now works also without);
69       => no longer needs barrier call after reading a file (added inside
70       mds_read/write field).
71     - move barrier calls outside gather/scatter_2d to mds_read/write_field
72    o pkg/obcs/exf
73      - exf_getffieldrec.F: add a few ". _d 0" and
74                            add code to catch the case fldperiod = 0.  
75      - obcs_precribe_read.F: change if statements so that they match
76                              the variable type (_RL)
77      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
78        exf_iprec) as part of namelist EXF_NML_01
79    o pkg/mdsio:
80      - read/write tiled (local) files: read/write 1-level tile chunk at a time
81        (instead of segment of length sNx); expected to speed up tiled IO.
82    o pkg/exch2:
83      - take buffer copy from/to array out of S/R exch2_send/recv into new
84        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
85        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
86      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
87      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
88        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
89        including Topology header file (and common blocks).
90      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
91        remove 2nd exch call in exch2_s3d_rx (no longer needed).
92      - document S/R arg. list (+ update some comments)
93    o pkg/seaice:
94      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
95        temperature and humidity over sea ice based on climatological values.
96      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
97        of LSR (this change is expected to change the results slightly because now
98        it uses slightly difference moduli from the second last LSR solution, but
99        that is more consistent with the stress computations; this part of the code
100        is not tested in the verification experiments)
101      - fix diagnostics for flux of ice in case of B-grid
102      - turn strain rates eij and press into global fields within global
103        common block in SEAICE.h for more straighforward diagnostics
104      - fix diagnostics for principal stress components, press, zeta, eta
105        to give something meaning full
106    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
107      new output (all 4 tests) using default rotationPeriod.
108    o pkg KPP:
109      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
110      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
111        and normal grid from 1 to Nr)
112    o Fix computations of L4rdt in mom_calc_visc.F
113    o eesupp:
114      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
115      should be called before a "stop" if we know that all process are going
116      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
117    
118    checkpoint61o
119    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
120    o model/src/ini_curvilinear_grid.F:
121       compute angleSin/CosC when they are not read from a file
122    o pkg/seaice:
123       add pseudo time stepping for LSOR
124    o pkg/exch2:
125       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
126    o pkg/seaice:
127       Adding separate sea ice albedo, drag coefficients, and HO in Southern
128       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
129    o SingleCpuIO:
130       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
131    o pkg/seaice:
132       put exchanged variable in (local) common block for MPI+Multi-Threads
133       to work (necessary with exch1, and for now with exch2 too).
134    o verification: to get more experiments tested with mpi, mth and mpi+mth,
135      change tiling of:
136       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
137       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
138      update output of exp:
139       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
140       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
141      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
142                       (note: output.txt generated on faulks using only 1 tile)
143    o eesupp & mdsio (SingleCpuIO):
144     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
145       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
146       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
147     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
148     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
149       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
150    o pkg/exch2:
151     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
152       read parameter file "data.exch2" if it exists; otherwise try default regular
153       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
154     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
155       with new code (not to be used, just as a backup solution).
156     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
157       in utils/exch2/input.
158    
159    checkpoint61n
160    o eesupp & mdsio (SingleCpuIO):
161      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
162        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
163        receive real*4 array (instead of real*8) to read/write 32.bit files.
164        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
165         and remove new mapping S/R)
166    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
167      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
168        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
169        when using exch2. Add S/R to map global io-buffer to global model array.
170      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
171    
172    checkpoint61m
173    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
174      and add 3 other S/R for other types (R4,R8,RS).
175      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
176    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
177     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
178     - reduce number of macro definitions (keep only those which are used);
179       can always call directly the corrresponding S/R if needed.
180     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
181       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
182     Fixed wrong type of arg in:
183       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
184       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
185     To fix: global_sum of var in common block is wrong (multi-threaded) in:
186       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
187     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
188    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
189      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
190    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
191    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
192      edges are closed (zero depth); might happen with "blank tiles";
193      for now, disabled if using OBCS.
194    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
195      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
196    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
197      to reduce length of 1.D array print in STDOUT.
198    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
199      + use 48 tiles (16x8): this will allow to test "blank tiles".
200    o start to test MPI + multi-threaded (change testreport to skip tests
201      where number of tiles do not match).
202    o genmake2: add option "-omp" to turn on Open-MP ;
203      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
204    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
205      and keep the original tile numbering. Note: compatible with old
206      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
207    
208    checkpoint61l
209    o Overlaps had been forgotten in calculating ijk keys : fixed
210    o fix cyrus makedepend for gcc 4.4
211    o experiment fizhi-cs-aqualev20:
212      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
213      and generate new output. Note: new output is much closer to the old
214      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
215      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
216    o pkg/fizhi:
217     - change to avoid indices going deliberately over array-bounds
218     - remove unnecessary MPI stuff
219     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
220     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
221       does not go over array-bounds and therefore returns reliable output.
222     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
223       this S/R has 4 output arguments, which are used inside "get_alarm";
224       when it is called with the same variable "ndum" in place of several
225       output arguments, this produces weird side effect inside "get_alarm"
226      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
227       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
228       address) and produces error.
229    o tools/gemake2: (March 27-29 2009)
230      with option "-mpi": link *_mpi files from "MODS" dir (this is what
231      testreport does).
232    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
233    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
234       update lab_sea.lsr & lab_sea.salt_plume results
235    o pkg/seaice:
236      Major overhaul of the LSOR solver: change discretization from original
237      finite differences to finite volume. The old routine is still in the
238      file seaice_lsr.F and can be turned on with the CPP-flag
239      SEAICE_OLD_AND_BAD_DISCRETIZATION
240      Along with this change, the discretization of the strain rates is changed.
241      The same flag turns on the old discretization in seaice_calc_strainrates.F
242      All verification experiments with seaice are affected (except for
243      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
244      results by setting the above flag.
245      Further changes involve changes in defaults:
246      - ALLOW_FLOODING is defined and turned on by default
247      - SEAICEadvSnow = .true. is now the default
248      - SEAICEadvSalt = .true. is now the default
249      - SEAICEadvAge  = .true. is now the default
250      - SEAICE_clipVelocities  = .false. is now the default
251                                         (as per J. Zhang's recommendation)
252      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
253        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
254      - seaice_growth: replace computation of UG by a simple copy from wspeed
255    
256    checkpoint61k
257    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
258      seaice_lsr: fixed a few metric terms,
259                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
260                  add more debugging diagnostics
261      seaice_evp: removed superfluous many metric terms of FV discretization
262                  of stress divergence
263                  affects lab_sea, lab_sea.hb87
264      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
265                  of stress divergence for non-evp solver
266                  (this part is not tested anywhere)
267      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
268                  they were effectively only half slip
269                  affects lab_sea.hb87
270      updated all relevant verification experiments (except lab_sea//output_adm.txt
271        which was left over, but fails at level 7 & 6)
272    
273    checkpoint61j
274    o pkg/seaice: turn a few hard wired parameters into run time parameters
275    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
276      time in seconds as promised by the usints in seaice_monitor and exf_monitor
277    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
278      that are not cubed-sphere grids
279    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
280    o pkg/ctrl:
281      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
282    o non-hydrostatic (calc_gw.F):
283      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
284      update output of exp. global_ocean.cs32x15.viscA4
285    o remove backward compatibility for thetaMin,phiMin
286      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
287    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
288      interpolated wind field not only for curvilineargrid=.true., but also
289      for a rotated grid (rotateGrid=.true.)
290    o pkg/exf: add capability to bypass interpolation for runoff
291      by setting yet another CPP-flag
292    o eesupp/src, B-grid exchange:
293      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
294    o autodiff
295      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
296      allows to switch to single-prec common blocks;
297      corresponding switch occurs in tamc.h, integer isbyte
298      TAF store directivs "byte" and "kind" seem equivalent;
299      Most tamc.h have been updated correspondingly.
300    
301    checkpoint61i
302    o autodiff:
303      fix autodiff_sore/_restore indices for obcs
304      (spotted by I. Hoteit, M. Mazloff)
305    o pkg/autodiff, pkg/ctrl:
306      Add flag to reduce all tapelev I/O to single-prec.
307      In data.ctrl set
308        doSinglePrecTapelev = .TRUE.
309    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
310      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
311    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
312      real fresh water flux (not yet)
313    o pkg/mdsio & rw:
314     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
315     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
316    o pkg/flt:
317     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
318       init_fixed & ini_varia.
319     - clean-up & simplify linear interpolation S/R:
320       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
321     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
322     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
323     - add vert. coordinate & horiz. indices to output files.
324     - change vertical position in initial condition, from index to depth [m].
325     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
326       (easier to get to a curvilinear grid) ; delX,delY no longer used.
327    o pkg/ggl90: a few modifications:
328     - fix bottom boundary condition, and interpolation of KappaE
329       near top and bottom
330     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
331     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
332     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
333    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
334      (maintain temporary backward compatibility, until next checkpoint)
335    
336    checkpoint61h
337    o pkg/diagnostics with "periodic averaging diagnostics":
338      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
339    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
340    o pkg/obcs: fix loop ranges for balancing code
341    o pkg/flt:
342     - improve criteria for finding which tile owns a float.
343     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
344    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
345      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
346      with ocean biogeo)
347    o pkg/flt:
348     - do some cleaning and fix the restart ;
349     - add output.txt in flt_example/results to get this pkg tested.
350    o genmake2: add an EXTENDED_SRC option and flag.
351       for now, cannot be turned on on command line (only through genmake_local)
352    o pkg/mdsio: read/write vector:
353     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
354     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
355       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
356     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
357      (drop to 4 digits matching for grad). But this test does not look very
358      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
359    
360    checkpoint61g
361    o pkg/flt:
362      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
363       + make OPTIONS file more standard.
364      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
365      - fix _BYTESWAPIO CPP-Flag
366      - standard reading of file-parameter "data.flt"
367      - fix argument list of S/R FLT_RESTART
368      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
369    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
370    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
371      a still unfixed compiler/optimization bug
372    
373    checkpoint61f
374  o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;  o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
375    update results of global_ocean.cs32x15.icedyn test.    update results of global_ocean.cs32x15.icedyn test.
376  o move getcon.F from model/src to pkg/fizhi.  o move getcon.F from model/src to pkg/fizhi.
