6    
7    o model/src: move balancing of relaxation terms to new S/R balance_relax.F.
8    o pkg/autodiff:
9      re-write active I/O high-level (control) S/R:
10      - rename  S/R ACTIVE_READ/WRITE_RL to ACTIVE_READ/WRITE_3D_RL
11      - add 1 more argument (useCurrentDir) to replace the "_LOC" 2nd set of S/R.
12      - use standard pkg/mdsio I/O routines (MDS_READ/WRITE_SEC_XZ/YZ  and
13        MDS_READ/WRITE_FIELD); change loops to multi-threads.
14      - update and merge active_file_control_slice.flow into active_file_control.flow
15      - update the calls in lower level S/R (active_file.F, active_file_g.F and
16        active_file_ad.F) keeping the argument list and function unchanged.
17      - also update lower-level "_LOC" version (call same S/R with "useCurrentDir
18        =.TRUE.") and remove high-level (control) _loc version (not called anymore).
19      - new low-level active I/O routines, one for each type (RL/RS), for active var
20        of various (XY,XZ,YZ) shape and level number (arguments: arrShape, myNr);
21        fix ctrl_init_wet.F & ecco_cost_weights.F by calling the new S/R with the
22        right type.
23    o autodiff and RS=real*4:
24      - call the right type (_RS instead of _RL) of S/R in few output S/R (pkg/exf
25        ad-monitor and snapshots); disable arrType='RS' in mdsio_gl*.F ;
26      - change argument type of 3-D mask argument to _RS to match type in the call
27        (in seaice_cost*.F, ctrl_*_gen.F and *ctrl_bound.F); to be continued.
28    o pkg/thsice:
29      - re-anable balanceEmPmR when useSEAICE=T with useThSIce=T.
30      - option to correct ocean fresh-water flux for imbalance of Atmos+Land
31        fresh-water flux: uniform correction or proportional to local precip.
32    o pkg/ctrl:
33      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
34      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
35                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
36      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
37    
38    checkpoint63q (2012/07/30)
39    o pkg/autodiff:
40      note about monitor and snap-shot of ad-variables:
41      a) need to apply ADEXCH before monitor or output of ad-vars to include
42       overlap contributions (was done for adjDump but missing for monitor).
43      b) since ADEXCH implies adding overlap values to interior array, machine
44       truncation error is expected when adding an ADEXCH call in the middle of
45       the time-stepping (although mathematically identical).
46      modifs:
47      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
48        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
49      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
50        apply ADEXCH before monitor or snap-shot of ad-variables:
51           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
52      - implement new method (copy+adexch) for snap-shot and monitor of main model
53        ad-vars (initially not used by default -> output unchanged).
54      - change default (set to 2) to use new method and update few output_adm.txt
55        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
56        and both tutorial_tracer_adjsens tests).
57      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
58        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
59    o pkg/ctrl:
60      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
61      generic control variables via
62      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
63      Only required customization should be S/R ctrl_map_ini_genarr.F
64      (routine in repository contains example)
65    o pkg/exf:
66      - fix and refine checking of surface-relaxation setting when using EXF
67    o verification (adjoint exp):
68      - reduce length of simulation by half for experiment global_ocean.cs32x15
69        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
70    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
71      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
72        of KE that can occur with aggressive optimization
73      + put quadratic bottom drag calculation in separated loops (only done if
74        using bottomDragQuadratic)
75    o model/src: CG2D_NSA
76      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
77         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
78      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
79         change cg2d residual target to be expressed in Wunits (=> do not normalise
80         RHS ; this fix global_max Pb with TAF); update output.
81  o verification/tutorial_tracer_adjsens:  o verification/tutorial_tracer_adjsens:
82     improve parameter consistencyi (and get rid of warnings):     improve parameter consistency (and get rid of warnings):
83     - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);     - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
84     - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)     - switch Temp Adv Scheme from 81 to 80 (no limiter since theta < 0 is physical)
85     - use staggerTimeStep (for stability) in som81; use default rotation period.     - use staggerTimeStep (for stability) in som81; use default rotation period.
