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):  o build_options: ifort+mpi_aces optfile (following Constantinos advise):
