4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o update output of exp. global_ocean.cs32x15.icedyn after removing
8      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
9    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
10    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
11      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
12    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
13      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
14      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
15      to test this code
16    o pkg/cd_code:
17      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
18       C-grid momentum. D-grid velocity used to be stepped forward in time with
19       Adams-Bashforth only on surface pressure term. Tests show that using AB on
20       D-grid coriolis term improves stability (as expected from CD-scheme paper).
21      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
22      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
23       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
24       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
25      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
26           lobal_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
27    o pkg/obcs:
28     - fix bug in initialisation (broken since Oct 1rst modification)
29       for useOBCSprescribe without useEXF.
30    
31    checkpoint61y
32    o pkg/seaice
33     - change (once again) the discretization for the evp solver: rather than
34       squaring the averages of strain rates, average the squares to give
35       a better approximation to VP behavior (in simple test); this breaks
36       verification experiments that use EVP (lab_sea and lab_sea.hb87)
37        --> update outputs
38    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
39      to improve vectorization of adjoint code on TARGET_NEC_SX
40    o verification/vermix:
41      - change vermix to a more "classical" 1d column with high vertical
42        resolution, seasonal heat flux forcing and constant wind forcing
43        --> update outputs
44    o pkg/seaice
45     - fix diagnostics of principal stress components for EVP
46     - add optional diagnostics of non-linear convergence for LSOR solver
47     - make maximum zeta a runtime parameter
48    o model/src (3-d solver):
49      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
50       which consisted in removing the Surf. Non-Hydrostatic pressure from the
51       whole column and adding it to Eta (inspired from Casualli, 1999):
52       Only affects 3-D solver initial guess and only if using ExactConserv,
53       but tests did show a degradation of solver convergence. For this reason,
54       decide to disable this piece of code.
55       to recover previous version, just set zeroPsNH = exactConserv (line 78).
56      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
57    o pkg/ggl90:
58     - fix previous modif (unfortunatly has not been documented here).
59    o pkg/seaice/autodiff:
60     - add CPP flag to include clipping of zeta in EVP code;
61       although clipping of zeta is not necessary for EVP and not recommended
62       it was done by default, now clipping is disabled by default
63     - modify computation and store zetaC/Z in seaice_evp for TAF
64     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
65     - change seaice_calc_viscosities/strainrates for better
66       vectorization after AD by TAF
67     - rearrange common blocks in SEAICE.h once again for easier dumps of
68       adjoint output, adjust adcommon.h and g_common.h
69     - change flux form of default advection scheme for better vectorization
70       of adjoint code
71     - modify lab_sea/input.lsr to test the flux form of default advection
72       scheme
73    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
74      transition in checkpoint61r)
75    
76    checkpoint61x
77    o adjoint: adding two new verification experiments
78      * tutorial_global_biogeo: an online dic sensitivity experiment
79        (work with G. Forget)
80      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
81        (an update of the Dutkiewicz et al., 2006 paper)
82      Both use the same CO2FLUX cost function, but different controls
83      Gradient checks look good, but some recomp. could still be traightened out
84      Should add xx_dic control variable to test at some point
85    o model/src:
86      add run-time parameters to check and/or mask initial Temp & Salt
87    o pkg/ptracers:
88      apply zonal filter (if used) to all passive tracers
89    
90    checkpoint61w
91    o adjoint:
92      * update and finish work on adjoint of dic package (G. Forget)
93      * start adjoint of offline package
94      * bug fix for cube-sphere TLM code (active_file_g.F)
95    o tutorial_global_oce_optim:
96      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
97      and add SIZE.h_mpi for MPI testing
98    o pkg autodiff
99     - fix bug in autodiff_restore
100     - make genmake2 remove comments and empty lines from ad_input_code.f in
101       order to reduce file size (new script file remove_comments_sed)
102    o allows to specify vertical profile of vertical viscosity (viscArNr)
103    o pkg autodiff
104      autodiff_ini_model_io: comment out writing of grid information to netcdf
105      files, because at this time the grid fields are a bunch of zeros
106      (this is analogous to ini_mnc_vars.F)
107    o pkg seaice/autodiff:
108     left-over from removing the 3-time-level fields:
109     - small rearrangement of common blocks (SEAICE.h)
110     - fix field declaration in order to get meaningful output in
111       adseaice.*.nc (adcommon.h)
112    o pkg obcs:
113     - go through NH code only if nonHydrostatic=T
114     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
115     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
116       => Update output of experiment seaice_obcs
117     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
118     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
119     - fix restart for useOBCSprescribe + useEXF
120    o pkg ctrl
121     - make obcs as control parameter work also with useSingleCPUio
122     - replace a few sny and snx by Ny and Nx to be consistent with
123       ctrl_set_globfld_x/yz.F
124    o pkg seaice
125     - re-introduce global field frWtrAtm for the case of
126       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
127     - catch the case of an empty filename in seaice_cost_init_fixed.F
128    o pkg ecco:
129     - small bug fixes in the_main_loop
130      . fix order of monitor arguments
131      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
132      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
133        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
134     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
135       imbalance diagnostics for wmean_h/sflux = 0
136     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
137     - catch the case of empty filenames in ecco_cost_init_fixed.F
138       and ecco_readparms.F
139     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
140       to make this statement meaningfull in ecco_cost_weights.F
141    o pkg zonal_filt:
142      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
143      - when using rStar, filter uVel*hFacW instead of uVel
144       (tested without topography: fix a Pb of growing instability with NLFS)
145    o pkg/aim/thsice:
146     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
147      (works as SST restoring)
148    o pkg/thsice:
149     -add specific parameter for salt restoring in slab mixed-layer
150       (by default equal to the temperature restoring)
151    
152    checkpoint61v
153    o pkg/kpp:
154     -add double diffusive contributions as a hack, turned off by default
155      for now, and the code can be excluded with a CPP-flag
156      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
157     -add a verification experiments to "vermix" to test this code
158    o pkg/mom_common:
159      Move computation of length scales to mom_init_fixed.F (avoid recomputation
160      at each time-steps*levels).
161    o pkg/layers:
162      Created a new package for computing volume fluxes in temperature or
163      [not yet implemented] density layers, e.g. for calculating residual
164      overturning circulations.
165    o pkg/diagnostics:
166      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
167    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
168    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
169      To avoid mixing type (RS/RL) of input/output array argument,
170      replace single mixed-type array with a pair from each type (RS/RL).
171    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
172      is now implemented for all pkgs (previously only done for the main pickup)
173    
174    checkpoint61u
175    o pkg/obcs:
176      - change OB?eta from _RS to _RL and put them into a separate commen block
177      - add code to read OB?eta from a file via obcs_prescribe_read: the code
178        compiles and does not destroy any other experiments, the data is read
179        properly, but the code is not tested in actual applications
180    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
181      create a meaningful unit attribute for the time coordinate variable
182    o pkg/ebm: add plenty of missing "_d 0" ;
183       update results of experiment global_ocean_ebm (fwd + adjoint tests)
184      Notes: several pieces of code only works for (very) specific set up
185       (domain size, lat range, etc ...); should be documented & stop if one
186       of those assumptions is not meet.
187    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
188       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
189          and offline_exf_seaice (seaicetd + adjoint).
190    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
191       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
192        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
193    o few changes to pass when compiling with strick checking of arguments
194       across S/R (allow to find few bugs in S/R calls).
195    o pkg/seaice:
196     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
197       2d-fields, for slightly better performance
198    
199    checkpoint61t
200    o pkg/seaice:
201     - remove unused variables in seaice_evp
202     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
203    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
204       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
205       each processor opens a different file (a fix from Matt).
206    o cg2d:
207       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
208       this reduces number of EXCH calls by 2 when using exch2.
209       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
210       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
211    o pkg/thsice:
212       add code for Near Infra-Red albedo (from Jeff)
213       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
214    o ini_model_io:
215       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
216       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
217       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
218    
219    checkpoint61s
220    o pkg/exch2 (exch2_rxN_cube*):
221       remove last BARRIER (no need to synchronise after getting data from shared
222       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
223    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
224      and generate new output (for the 2 tests) using default rotationPeriod.
225    o pkg/exch2:
226      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
227        (was already the case with AUTODIFF_EXCH2 defined)
228      - add bj in exch2 arrays and S/R.
229      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
230        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
231    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
232      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
233        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
234      - verification experiment natl_box.longstep
235    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
236      allow different versions of ifort (8 or 9) and different versions
237       of mpi (mpich or mpich2) to be used with the same optfile.
238      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
239       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
240    o pkg/seaice:
241      fix previous modif (3-level field removed) for old-pickup reading
242    
243    checkpoint61r
244    o pkg/seaice:
245     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
246      1. introduce fields for time step (N-1)
247      2. do not use levels 2 and 3 anymore (but keep them)
248      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
249         includes changes to pkg/thsice/thsice_get_velocity.F,
250         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
251         pkg/obcs/obcs_apply_uvice.F.
252     - completely remove code for leap-frog time stepping for second order
253       advection
254     - adjusted adjoint accordingly;
255       gradient checks have improved by an order of magnitude!
256    
257    checkpoint61q
258    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
259     - the boundary conditions along open boundaries are unclear, because the
260       associated masks are set to zero and are thus treated as closed when
261       applying the slip-boundary conditions.
262     - move initialisation of grid variables from seaice_init_varia to _fixed
263    o adding doc/diags_changes.txt
264    o model/src:
265      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
266       to avoid "_diags" naming if no relation to pkg/diagnostics.
267      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
268       file and only call PLOT_FIELD_XYZ if debugMode=T.
269      remove few PLOT_FIELD_XY calls outside initialisation.
270      remove few unnecessary BARRIER.
271    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
272      of salt_plume package in Southern Ocean
273    o pkg/thsice:
274     - fix hOceMxL in overlap (needed for sea-ice advection);
275       update output of experiment global_ocean.cs32x15.icedyn.
276    o pkg/seaice:
277     - make the (placeholder-)tracer IceAge a little more meaningful
278      by avoiding ridging of age due to convergent ice flow
279     - add diagnostics for surface temperature, atmospheric and oceanic
280       heat flux, and atmospheric and oceanic ice growth
281    
282    checkpoint61p
283    o eesupp (global_max & global_sum):
284     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
285     - remove starting & endding barrier (no longer needed)
286    o pkg/mdsio, writelocal:
287       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
288       (remove the STOP): uses shared buffer IO to store data from all threads
289       and then let master-thread write nThreads tiles.
290    o pkg/mdsio (read/write field):
291     - tiled IO done in 1 piece (all levels at a time);
292     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
293     - multi-threaded: allow to read/write local (non-shared) array
294       (was already working with singleCpuIO ; now works also without);
295       => no longer needs barrier call after reading a file (added inside
296       mds_read/write field).
297     - move barrier calls outside gather/scatter_2d to mds_read/write_field
298    o pkg/obcs/exf
299      - exf_getffieldrec.F: add a few ". _d 0" and
300                            add code to catch the case fldperiod = 0.  
301      - obcs_precribe_read.F: change if statements so that they match
302                              the variable type (_RL)
303      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
304        exf_iprec) as part of namelist EXF_NML_01
305    o pkg/mdsio:
306      - read/write tiled (local) files: read/write 1-level tile chunk at a time
307        (instead of segment of length sNx); expected to speed up tiled IO.
308    o pkg/exch2:
309      - take buffer copy from/to array out of S/R exch2_send/recv into new
310        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
311        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
312      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
313      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
314        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
315        including Topology header file (and common blocks).
316      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
317        remove 2nd exch call in exch2_s3d_rx (no longer needed).
318      - document S/R arg. list (+ update some comments)
319    o pkg/seaice:
320      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
321        temperature and humidity over sea ice based on climatological values.
322      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
323        of LSR (this change is expected to change the results slightly because now
324        it uses slightly difference moduli from the second last LSR solution, but
325        that is more consistent with the stress computations; this part of the code
326        is not tested in the verification experiments)
327      - fix diagnostics for flux of ice in case of B-grid
328      - turn strain rates eij and press into global fields within global
329        common block in SEAICE.h for more straighforward diagnostics
330      - fix diagnostics for principal stress components, press, zeta, eta
331        to give something meaning full
332    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
333      new output (all 4 tests) using default rotationPeriod.
334    o pkg KPP:
335      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
336      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
337        and normal grid from 1 to Nr)
338    o Fix computations of L4rdt in mom_calc_visc.F
339    o eesupp:
340      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
341      should be called before a "stop" if we know that all process are going
342      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
343    
344    checkpoint61o
345    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
346    o model/src/ini_curvilinear_grid.F:
347       compute angleSin/CosC when they are not read from a file
348    o pkg/seaice:
349       add pseudo time stepping for LSOR
350    o pkg/exch2:
351       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
352    o pkg/seaice:
353       Adding separate sea ice albedo, drag coefficients, and HO in Southern
354       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
355    o SingleCpuIO:
356       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
357    o pkg/seaice:
358       put exchanged variable in (local) common block for MPI+Multi-Threads
359       to work (necessary with exch1, and for now with exch2 too).
360    o verification: to get more experiments tested with mpi, mth and mpi+mth,

368                       (note: output.txt generated on faulks using only 1 tile)
369    o eesupp & mdsio (SingleCpuIO):
370     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
371       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
372       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
373     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
374     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
375       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
376  o pkg/exch2:  o pkg/exch2:
