5      ==============================      ==============================
6    
7    o pkg/ctrl:
8      - new header file CTRL_SIZE.h for parameters maxCtrlArr2D, maxCtrlArr3D
9      - redefine CPP option ALLOW_BOTTOMDRAG_CONTROL to
10                            ALLOW_BOTTOMDRAG_CONTROL_NONGENERIC
11      - verification/hs94.1x64x5/ tests ALLOW_GENARR{2D,3D}_CONTROL
12    checkpoint63q (2012/07/30)
13    o pkg/autodiff:
14      note about monitor and snap-shot of ad-variables:
15      a) need to apply ADEXCH before monitor or output of ad-vars to include
16       overlap contributions (was done for adjDump but missing for monitor).
17      b) since ADEXCH implies adding overlap values to interior array, machine
18       truncation error is expected when adding an ADEXCH call in the middle of
19       the time-stepping (although mathematically identical).
20      modifs:
21      - fix some incorrect type (RL/RS, UV/scalar) in ADEXCH calls and ad-vars
22        declaration (adEddyPsiX,adEddyPsiY in adcommon.h).
23      - add new run-time params (dumpAdVarExch & mon_AdVarExch) to select how  to
24        apply ADEXCH before monitor or snap-shot of ad-variables:
25           =0 : no ADEXCH ; =1 : do ADEXCH ; =2 : apply ADEXCH on a local copy.
26      - implement new method (copy+adexch) for snap-shot and monitor of main model
27        ad-vars (initially not used by default -> output unchanged).
28      - change default (set to 2) to use new method and update few output_adm.txt
29        with accurate ad-monitor (global_ocean.90x40x15, tutorial_global_oce_biogeo
30        and both tutorial_tracer_adjsens tests).
31      - switch 2 global_ocean.cs32x15 AD-tests to AB-2 (seaice_dynmix & thsice)
32        and turn off momDissip_In_AB in the 2 other (needed for stable AB-3).
33    o pkg/ctrl:
34      enable the use of a variable number (maxCtrlArr2D, maxCtrlArr3D) of
35      generic control variables via
36      #define ALLOW_GENARR2D_CONTROL and/or #define ALLOW_GENARR3D_CONTROL
37      Only required customization should be S/R ctrl_map_ini_genarr.F
38      (routine in repository contains example)
39    o pkg/exf:
40      - fix and refine checking of surface-relaxation setting when using EXF
41    o verification (adjoint exp):
42      - reduce length of simulation by half for experiment global_ocean.cs32x15
43        (std, seaice & seaice_dynmix) and exp tutorial_dic_adjoffline; update output.
44    o pkg/mom_common (mom_u/v_bottomdrag), pkg/shelfice (shelfice_u/v_drag)
45      - replace if statements KE.ne.0 with KE.gt.0 to avoid sqrt of negative numbers
46        of KE that can occur with aggressive optimization
47      + put quadratic bottom drag calculation in separated loops (only done if
48        using bottomDragQuadratic)
49    o model/src: CG2D_NSA
50      - clean-up:  stop if cg2dNormaliseRHS=T and AUTODIFF
51         and replace GLOBAL_SUM calls with GLOBAL_SUM_TILE.
52      - in test-exp that uses CG2D_NSA (bottom_ctrl & tutorial_tracer_adjsens),
53         change cg2d residual target to be expressed in Wunits (=> do not normalise
54         RHS ; this fix global_max Pb with TAF); update output.
55  o verification/tutorial_tracer_adjsens:  o verification/tutorial_tracer_adjsens:
56     improve parameter consistencyi (and get rid of warnings):     improve parameter consistency (and get rid of warnings):
57     - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);     - use deltaTFreeSurf=deltaTtracer (better with NonLin FreeSurf);
58     - 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)
59     - use staggerTimeStep (for stability) in som81; use default rotation period.     - use staggerTimeStep (for stability) in som81; use default rotation period.
