7    checkpoint62l (2010/10/04)
8    o pkg/seaice:
9      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
10      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
11       version (with USE_ORIGINAL_SBI undef);
12    o add hooks for new packages OASIS, the package will follow
13      (hooks exclude the seaice pkg for now)
14    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
15      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
16      rather than mdsio_readvector.F/mdsio_writevector.F, within
17      adread_adwrite.F to read/write adjoint-related tapes to disk.
18    o eesupp and pkg/mdsio: ALLOW_WHIO
19      Option to write/read 2D fields to files including tiles halos.
20      The main purpose is for adjoint related "tape I/O".
21      The secondary purpose is for debugging phases.
22      A word on those rather specifically intended purposes.
23      The code was meant to be stripped down to the bare minimum.
24      Typically, there is a unique and basic mapping to the global
25      buffer (tile by tile, then proc by proc, then level by level), and
26      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
27      meant to generate user friendly outputs of various shapes and forms.
28      Rather it is intended, for the knowledgeabale developers,
29      to be largely independent of the many mdsio options, to allow
30      outputs of tiles+halos in debugging phases and in adjoint runs,
31      and to allow some flexibility in tuning (adoint) I/O depending on each
32      file system behavior. With regard to tuning, most of the potential knobs
33      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
34      to specify directories, to specify the typical size of I/O calls, etc.)
35      are not yet included, and will be added if they prove useful.
36    o pkg/seaice:
37       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
38    o pkg/seaice:
39       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
40       code (seaice_budget_ice_if.F) which enable to recover old standard
41       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
42       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
43    o model/src (rStar):
44       use simple average (not area weighted) of rStarFac at U,V point when using
45       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
46       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
47    
48    checkpoint62k (2010/09/17)
49    o adjoint
50       * changed verification/global_ocean.cs32x15 ; adjoint now tests
51         Adams-Bashforth 3 + NLFS + RSTAR
52       * some more modifs required for ECCO-GODAE v4
53    o pkg/seaice
54       add SEAICE_AGE_VOL option to use volume instead of area for
55       integrating SEAICE_AGE
56    o model/src:
57       first check-in of sigma & hybrid-sigma coordinate code ; also includes
58       non-linear free-surface parts ; but pressure-gradient not yet coded.
59    o pkg/ptracers:
60       option for ptracer to convert Salt Relax into additional EmP.
61        tested in exp. global_ocean.90x40x15.dwnslp (update output)
62    
63    checkpoint62j (2010/08/25)
64    o pkg/ggl90:
65       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
66    o pkg/dic: car_flux.F, phos_flux.F
67      - reduce number of exp-calls in order to improve performance
68      - clean up a little (replace fields by their macros, etc., fix
69        typo in CPP-flag)
70    o pkg/ggl90: minor changes
71      - GGL90diffKrS was removed --> always use GGL90diffKr
72      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
73      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
74        (commented out for now)
75      - change in max/min operations to ensure that smoothing is ok
76      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
77      - always use diffKrNrT as background profile (i.e. never use diffKr field)
78    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
79    o pkg/dic:
80      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
81        vectorization
82      - small bug fix in insol for the unlikely case of a cartesian grid
83      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
84        + now vectorize, which also removes adjoint recomputations;
85        + replace integer maksp1 by _RL maskp1
86        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
87    
88    checkpoint62i (2010/07/21)
89    o pkg/flt:
90      - with OBCS: stop floats which enter the OB region
91    o model/src:
92      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
93        for implicit vertical advection.
94    o pkg/seaice:
95     - account for melting in seaice age evolution.
96     - remove double counting of seaice ridging effect on seaice age.
97    
98    checkpoint62h (2010/06/18)
99    o pkg/exch2:
100     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
101    o tools/genmake2
102      - remove "-pdefault" option: redundant with the use of "packages.conf";
103      - remove file pkg/pkg_default : set the default as a pkg group
104        ("default_pkg_list") defined in pkg/pkg_groups;
105      - fix for case pkg/pkg_depend is missing (was hanging before);
106      - add option "-pgroups" to specify a different pkg_groups than the default.
107    o verification/adjustment.cs-32x32x1:
108       add a "minimal" set-up test (code_min & input_min) which only compiles
109       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
110    o tools/genmake2
111      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
112      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
113  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
