4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
9      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
10       version (with USE_ORIGINAL_SBI undef);
11    o add hooks for new packages OASIS, the package will follow
12      (hooks exclude the seaice pkg for now)
13    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
14      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
15      rather than mdsio_readvector.F/mdsio_writevector.F, within
16      adread_adwrite.F to read/write adjoint-related tapes to disk.
17    o eesupp and pkg/mdsio: ALLOW_WHIO
18      Option to write/read 2D fields to files including tiles halos.
19      The main purpose is for adjoint related "tape I/O".
20      The secondary purpose is for debugging phases.
21      A word on those rather specifically intended purposes.
22      The code was meant to be stripped down to the bare minimum.
23      Typically, there is a unique and basic mapping to the global
24      buffer (tile by tile, then proc by proc, then level by level), and
25      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
26      meant to generate user friendly outputs of various shapes and forms.
27      Rather it is intended, for the knowledgeabale developers,
28      to be largely independent of the many mdsio options, to allow
29      outputs of tiles+halos in debugging phases and in adjoint runs,
30      and to allow some flexibility in tuning (adoint) I/O depending on each
31      file system behavior. With regard to tuning, most of the potential knobs
32      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
33      to specify directories, to specify the typical size of I/O calls, etc.)
34      are not yet included, and will be added if they prove useful.
35    o pkg/seaice:
36       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
37    o pkg/seaice:
38       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
39       code (seaice_budget_ice_if.F) which enable to recover old standard
40       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
41       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
42    o model/src (rStar):
43       use simple average (not area weighted) of rStarFac at U,V point when using
44       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
45       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
46    
47    checkpoint62k (2010/09/17)
48    o adjoint
49       * changed verification/global_ocean.cs32x15 ; adjoint now tests
50         Adams-Bashforth 3 + NLFS + RSTAR
51       * some more modifs required for ECCO-GODAE v4
52    o pkg/seaice
53       add SEAICE_AGE_VOL option to use volume instead of area for
54       integrating SEAICE_AGE
55    o model/src:
56       first check-in of sigma & hybrid-sigma coordinate code ; also includes
57       non-linear free-surface parts ; but pressure-gradient not yet coded.
58    o pkg/ptracers:
59       option for ptracer to convert Salt Relax into additional EmP.
60        tested in exp. global_ocean.90x40x15.dwnslp (update output)
61    
62    checkpoint62j (2010/08/25)
63    o pkg/ggl90:
64       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
65    o pkg/dic: car_flux.F, phos_flux.F
66      - reduce number of exp-calls in order to improve performance
67      - clean up a little (replace fields by their macros, etc., fix
68        typo in CPP-flag)
69    o pkg/ggl90: minor changes
70      - GGL90diffKrS was removed --> always use GGL90diffKr
71      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
72      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
73        (commented out for now)
74      - change in max/min operations to ensure that smoothing is ok
75      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
76      - always use diffKrNrT as background profile (i.e. never use diffKr field)
77    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
78    o pkg/dic:
79      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
80        vectorization
81      - small bug fix in insol for the unlikely case of a cartesian grid
82      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
83        + now vectorize, which also removes adjoint recomputations;
84        + replace integer maksp1 by _RL maskp1
85        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
86    
87    checkpoint62i (2010/07/21)
88    o pkg/flt:
89      - with OBCS: stop floats which enter the OB region
90    o model/src:
91      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
92        for implicit vertical advection.
93    o pkg/seaice:
94     - account for melting in seaice age evolution.
95     - remove double counting of seaice ridging effect on seaice age.
96    
97    checkpoint62h (2010/06/18)
98    o pkg/exch2:
99     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
100    o tools/genmake2
101      - remove "-pdefault" option: redundant with the use of "packages.conf";
102      - remove file pkg/pkg_default : set the default as a pkg group
103        ("default_pkg_list") defined in pkg/pkg_groups;
104      - fix for case pkg/pkg_depend is missing (was hanging before);
105      - add option "-pgroups" to specify a different pkg_groups than the default.
106    o verification/adjustment.cs-32x32x1:
107       add a "minimal" set-up test (code_min & input_min) which only compiles
108       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
109    o tools/genmake2
110      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
111      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
112  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these  o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
