4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    checkpoint61v
8    o pkg/kpp:
9     -add double diffusive contributions as a hack, turned off by default
10      for now, and the code can be excluded with a CPP-flag
11      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
12     -add a verification experiments to "vermix" to test this code
13    o pkg/mom_common:
14      Move computation of length scales to mom_init_fixed.F (avoid recomputation
15      at each time-steps*levels).
16    o pkg/layers:
17      Created a new package for computing volume fluxes in temperature or
18      [not yet implemented] density layers, e.g. for calculating residual
19      overturning circulations.
20    o pkg/diagnostics:
21      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
22    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
23    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
24      To avoid mixing type (RS/RL) of input/output array argument,
25      replace single mixed-type array with a pair from each type (RS/RL).
26    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
27      is now implemented for all pkgs (previously only done for the main pickup)
28    
29    checkpoint61u
30    o pkg/obcs:
31      - change OB?eta from _RS to _RL and put them into a separate commen block
32      - add code to read OB?eta from a file via obcs_prescribe_read: the code
33        compiles and does not destroy any other experiments, the data is read
34        properly, but the code is not tested in actual applications
35    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
36      create a meaningful unit attribute for the time coordinate variable
37    o pkg/ebm: add plenty of missing "_d 0" ;
38       update results of experiment global_ocean_ebm (fwd + adjoint tests)
39      Notes: several pieces of code only works for (very) specific set up
40       (domain size, lat range, etc ...); should be documented & stop if one
41       of those assumptions is not meet.
42    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
43       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
44          and offline_exf_seaice (seaicetd + adjoint).
45    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
46       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
47        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
48    o few changes to pass when compiling with strick checking of arguments
49       across S/R (allow to find few bugs in S/R calls).
50    o pkg/seaice:
51     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
52       2d-fields, for slightly better performance
53    
54    checkpoint61t
55    o pkg/seaice:
56     - remove unused variables in seaice_evp
57     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
58    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
59       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
60       each processor opens a different file (a fix from Matt).
61    o cg2d:
62       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
63       this reduces number of EXCH calls by 2 when using exch2.
64       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
65       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
66    o pkg/thsice:
67       add code for Near Infra-Red albedo (from Jeff)
68       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
69    o ini_model_io:
70       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
71       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
72       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
73    
74    checkpoint61s
75    o pkg/exch2 (exch2_rxN_cube*):
76       remove last BARRIER (no need to synchronise after getting data from shared
77       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
78    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
79      and generate new output (for the 2 tests) using default rotationPeriod.
80    o pkg/exch2:
81      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
82        (was already the case with AUTODIFF_EXCH2 defined)
83      - add bj in exch2 arrays and S/R.
84      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
85        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
86    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
87      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
88        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
89      - verification experiment natl_box.longstep
90    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
91      allow different versions of ifort (8 or 9) and different versions
92       of mpi (mpich or mpich2) to be used with the same optfile.
93      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
94       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
95    o pkg/seaice:
96      fix previous modif (3-level field removed) for old-pickup reading
97    
98    checkpoint61r
99    o pkg/seaice:
100     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
101      1. introduce fields for time step (N-1)
102      2. do not use levels 2 and 3 anymore (but keep them)
103      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
104         includes changes to pkg/thsice/thsice_get_velocity.F,
105         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
106         pkg/obcs/obcs_apply_uvice.F.
107     - completely remove code for leap-frog time stepping for second order
108       advection
109     - adjusted adjoint accordingly;
110       gradient checks have improved by an order of magnitude!
111    
112    checkpoint61q
113    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
114     - the boundary conditions along open boundaries are unclear, because the
115       associated masks are set to zero and are thus treated as closed when
116       applying the slip-boundary conditions.
117     - move initialisation of grid variables from seaice_init_varia to _fixed
118    o adding doc/diags_changes.txt
119    o model/src:
120      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
121       to avoid "_diags" naming if no relation to pkg/diagnostics.
122      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
123       file and only call PLOT_FIELD_XYZ if debugMode=T.
124      remove few PLOT_FIELD_XY calls outside initialisation.
125      remove few unnecessary BARRIER.
126    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
127      of salt_plume package in Southern Ocean
128    o pkg/thsice:
129     - fix hOceMxL in overlap (needed for sea-ice advection);
130       update output of experiment global_ocean.cs32x15.icedyn.
131    o pkg/seaice:
132     - make the (placeholder-)tracer IceAge a little more meaningful
133      by avoiding ridging of age due to convergent ice flow
134     - add diagnostics for surface temperature, atmospheric and oceanic
135       heat flux, and atmospheric and oceanic ice growth
136    
137    checkpoint61p
138    o eesupp (global_max & global_sum):
139     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
140     - remove starting & endding barrier (no longer needed)
141    o pkg/mdsio, writelocal:
142       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
143       (remove the STOP): uses shared buffer IO to store data from all threads
144       and then let master-thread write nThreads tiles.
145    o pkg/mdsio (read/write field):
146     - tiled IO done in 1 piece (all levels at a time);
147     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
148     - multi-threaded: allow to read/write local (non-shared) array
149       (was already working with singleCpuIO ; now works also without);
150       => no longer needs barrier call after reading a file (added inside
151       mds_read/write field).
152     - move barrier calls outside gather/scatter_2d to mds_read/write_field
153    o pkg/obcs/exf
154      - exf_getffieldrec.F: add a few ". _d 0" and
155                            add code to catch the case fldperiod = 0.  
156      - obcs_precribe_read.F: change if statements so that they match
157                              the variable type (_RL)
158      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
159        exf_iprec) as part of namelist EXF_NML_01
160    o pkg/mdsio:
161      - read/write tiled (local) files: read/write 1-level tile chunk at a time
162        (instead of segment of length sNx); expected to speed up tiled IO.
163    o pkg/exch2:
164      - take buffer copy from/to array out of S/R exch2_send/recv into new
165        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
166        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
167      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
168      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
169        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
170        including Topology header file (and common blocks).
171      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
172        remove 2nd exch call in exch2_s3d_rx (no longer needed).
173      - document S/R arg. list (+ update some comments)
174    o pkg/seaice:
175      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
176        temperature and humidity over sea ice based on climatological values.
177      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
178        of LSR (this change is expected to change the results slightly because now
179        it uses slightly difference moduli from the second last LSR solution, but
180        that is more consistent with the stress computations; this part of the code
181        is not tested in the verification experiments)
182      - fix diagnostics for flux of ice in case of B-grid
183      - turn strain rates eij and press into global fields within global
184        common block in SEAICE.h for more straighforward diagnostics
185      - fix diagnostics for principal stress components, press, zeta, eta
186        to give something meaning full
187  o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate  o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
188    new output (all 4 tests) using default rotationPeriod.    new output (all 4 tests) using default rotationPeriod.
189    o pkg KPP:
190      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
191      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
192        and normal grid from 1 to Nr)
193  o Fix computations of L4rdt in mom_calc_visc.F  o Fix computations of L4rdt in mom_calc_visc.F
194  o eesupp:  o eesupp:
195    new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):    new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
