5      ==============================      ==============================
6    
7    checkpoint61d
8    o adjoint modifs
9      - adapt to new field rhoInSitu
10      - allow to revert from StoreDynVars2D, StoreDynVars3D
11        to individual fields
12        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
13    o store 3-D (in-situ) density in commom block (DYNVARS.h)
14     - save 1 rho computation.
15     - no longer modify T & S inland when using down_slope pkg.
16    o gad_som : allow to switch to SOM advection for T & S without corresponding
17      pickup files (using new S/R: MDS_CHECK4FILE).
18    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
19      (for useSingleCpuIO to work in multi-threaded)
20    o pkg/shelfice:
21     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
22       with SHELFICEtopoFile in data.shelfice
23     - move code for reading ice shelf topography and modifying hFacC into separate
24       subroutines of the shelfice package
25     - separate initialisation of "fixed" and "variable" variables
26     - kTopC is not (yet) replaced by kSurfC, although this is possible
27    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
28    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
29      and rename:
30      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
31      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
32    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
33    
34    checkpoint61c
35    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
36      to add mass source/sink of fluid in the interior (3-D generalisation
37      of oceanic real-fresh water flux).
38    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
39    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
40    o new pkg: down_slope
41      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
42      - presently, modify T & S inland (dwnslp_calc_rho.F).
43        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
44      - implementation for ocean in P-coords not tested.
45      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
46    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
47      (to facilitate conversion of oceanic pkg to p-coordinate).
48    o change FIND_RHO to FIND_RHO_2D :
49      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
50    o new pkg: cheapaml
51    
52    checkpoint61b
53    o exch2:
54      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
55      - no longer depend on the order sequence (N,S,E,W).
56      - 3rd exchange no longer needed (tested with 24 tiles).
57      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
58      - exch_UV_A-grid readily available (but not yet tested).
59      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
60      (both are no longer needed) in exch_uv: no effect in forward run; but
61       get truncation error differences with adjoint exch.
62    o exch2:
63     - change index-bounds storage (moved from target to local tile,
64       more intuitive this way) ; rename/remove some variables.
65     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
66    
67    checkpoint61a
68    o exch2/matlab-topology-generator:
69      fix bug in index bounds for N-S internal exchange (hard to tell if this
70      had any effect on the solution).
71    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
72      is exceeded
73    o testreport: modify syntax of awk, so that it works also with
74      awk, and not only with nawk and gawk
75    
76    checkpoint61
77    o autodiff
78      Change default for TAF usage by removing argument '-nonew_arg'
79      This changes TAF subroutine argument list (ordering of active var.)
80      Omission of this flag leads to incompatibility w.r.t. TAMC
81      To restore TAMC-compatibility, need following modifs:
82      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
83      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
84      Tested TAF version is 1.9.22
85      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
86    
87    checkpoint60
88    --->>> This is the last checkpoint for which generating the adjoint
89    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
90    --->>> by default.
91    --->>> Future checkpoints will ommit this flag by default.
92    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
93    o pkg/grdchk: Add gradient check to etan0 perturbations.
94  o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).  o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
95  o pkg/autodiff: more flexibility in zeroadj.  o pkg/autodiff: more flexibility in zeroadj.
96    model/src: modifying do_oceanic_phys.F accordingly.    model/src: modifying do_oceanic_phys.F accordingly.
