4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ebm: add plenty of missing "_d 0" ;
8       update results of experiment global_ocean_ebm (fwd + adjoint tests)
9      Notes: several pieces of code only works for (very) specific set up
10       (domain size, lat range, etc ...); should be documented & stop if one
11       of those assumptions is not meet.
12    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
13       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
14          and offline_exf_seaice (seaicetd + adjoint).
15    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
16       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
17        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
18    o few changes to pass when compiling with strick checking of arguments
19       across S/R (allow to find few bugs in S/R calls).
20    o pkg/seaice:
21     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
22       2d-fields, for slightly better performance
23    
24    checkpoint61t
25    o pkg/seaice:
26     - remove unused variables in seaice_evp
27     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
28    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
29       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
30       each processor opens a different file (a fix from Matt).
31    o cg2d:
32       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
33       this reduces number of EXCH calls by 2 when using exch2.
34       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
35       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
36    o pkg/thsice:
37       add code for Near Infra-Red albedo (from Jeff)
38       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
39    o ini_model_io:
40       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
41       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
42       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
43    
44    checkpoint61s
45    o pkg/exch2 (exch2_rxN_cube*):
46       remove last BARRIER (no need to synchronise after getting data from shared
47       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
48    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
49      and generate new output (for the 2 tests) using default rotationPeriod.
50    o pkg/exch2:
51      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
52        (was already the case with AUTODIFF_EXCH2 defined)
53      - add bj in exch2 arrays and S/R.
54      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
55        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
56    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
57      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
58        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
59      - verification experiment natl_box.longstep
60    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
61      allow different versions of ifort (8 or 9) and different versions
62       of mpi (mpich or mpich2) to be used with the same optfile.
63      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
64       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
65    o pkg/seaice:
66      fix previous modif (3-level field removed) for old-pickup reading
67    
68    checkpoint61r
69    o pkg/seaice:
70     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
71      1. introduce fields for time step (N-1)
72      2. do not use levels 2 and 3 anymore (but keep them)
73      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
74         includes changes to pkg/thsice/thsice_get_velocity.F,
75         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
76         pkg/obcs/obcs_apply_uvice.F.
77     - completely remove code for leap-frog time stepping for second order
78       advection
79     - adjusted adjoint accordingly;
80       gradient checks have improved by an order of magnitude!
81    
82    checkpoint61q
83    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
84     - the boundary conditions along open boundaries are unclear, because the
85       associated masks are set to zero and are thus treated as closed when
86       applying the slip-boundary conditions.
87     - move initialisation of grid variables from seaice_init_varia to _fixed
88    o adding doc/diags_changes.txt
89    o model/src:
90      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
91       to avoid "_diags" naming if no relation to pkg/diagnostics.
92      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
93       file and only call PLOT_FIELD_XYZ if debugMode=T.
94      remove few PLOT_FIELD_XY calls outside initialisation.
95      remove few unnecessary BARRIER.
96  o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling  o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
97    of salt_plume package in Southern Ocean    of salt_plume package in Southern Ocean
