|
o pkg/obcs: add support for exch2 |
8 |
|
- the position of the boundary and prescribed values are specified using |
9 |
|
a global domain with exch2 facets stacked |
10 |
|
- in x for N,S boundaries (like W2_mapIO=-1) |
11 |
|
- in y for E,W boundaries (so E,W boundaries do not overlap) |
12 |
|
o pkg/mdsio: add support for writing global sections with exch2 |
13 |
|
file layout is as for obcs described above: |
14 |
|
- for x-z sections, facets are stacked in x (like W2_mapIO=-1) |
15 |
|
- for y-z sections, facets are stacked in y |
16 |
|
o pkg/thsice: |
17 |
|
- change a few routines for better vectorization: thsice_albedo.F, |
18 |
|
thsice_step_temp.F, and in thsice_calc_thickn.F. Results are |
19 |
|
not affected, but in particular the latter routine has changed |
20 |
|
dramatically (not necessarily easier to read now). |
21 |
|
- re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops |
22 |
|
iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF. |
23 |
|
o verification/lab_sea: |
24 |
|
- overhaul of the forward model experiments. The main motivation |
25 |
|
for this revision is that lab_sea has proven quite fragile (when |
26 |
|
changing the sea-ice code, and switching platforms) to a point |
27 |
|
when failures were very hard to attribute to specific code problems. |
28 |
|
- the suspected reason for this fragility is noise amplification by evp so, |
29 |
|
to start with, we decided to replace evp with lsr in the main experiment. |
30 |
|
- the input.lsr experiment thus became obsolete and was removed. |
31 |
|
- it was replaced with the input.fd experiment that uses an |
32 |
|
analytical "free drift" solution as the ice velocity field. |
33 |
|
- Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp) |
34 |
|
will hopefully allow us to discriminate problems due to dynamic solvers |
35 |
|
from problems due to the thermodynamic code. input.salt_plume (lsr) allows |
36 |
|
us to test additional options, along with the salt plume package. |
37 |
|
- Finally a pickup was generated (at the end of a one year run) to |
38 |
|
make the tests more representative of an actual model run. Previously |
39 |
|
the tests starting point was a 1m thickness of ice everywhere. |
40 |
|
o pkg/seaice: |
41 |
|
- introducing S\R seaice_freedrift.F that compute the |
42 |
|
analytical solution to an approximate ice momentum |
43 |
|
equation (i.e. the simple stress/coriolis balance). |
44 |
|
- define SEAICE_ALLOW_FREEDRIFT to trigger the computation |
45 |
|
of the free drift velocity field, and enable its use. |
46 |
|
To actually use the free drift solution as the model ice |
47 |
|
velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice. |
48 |
|
o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata" |
49 |
|
|

|
checkpoint62l (2010/10/04) |
51 |
|
o pkg/seaice: |
52 |
|
-fix the USE_ORIGINAL_SBI version (for variable freezing point); |
53 |
|
-use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new |
54 |
|
version (with USE_ORIGINAL_SBI undef); |
55 |
|
o add hooks for new packages OASIS, the package will follow |
56 |
|
(hooks exclude the seaice pkg for now) |
57 |
|
o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO |
58 |
|
Option to use mdsio_read_whalos.F/mdsio_write_whalos.F, |
59 |
|
rather than mdsio_readvector.F/mdsio_writevector.F, within |
60 |
|
adread_adwrite.F to read/write adjoint-related tapes to disk. |
61 |
|
o eesupp and pkg/mdsio: ALLOW_WHIO |
62 |
|
Option to write/read 2D fields to files including tiles halos. |
63 |
|
The main purpose is for adjoint related "tape I/O". |
64 |
|
The secondary purpose is for debugging phases. |
65 |
|
A word on those rather specifically intended purposes. |
66 |
|
The code was meant to be stripped down to the bare minimum. |
67 |
|
Typically, there is a unique and basic mapping to the global |
68 |
|
buffer (tile by tile, then proc by proc, then level by level), and |
69 |
|
byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not |
70 |
|
meant to generate user friendly outputs of various shapes and forms. |
71 |
|
Rather it is intended, for the knowledgeabale developers, |
72 |
|
to be largely independent of the many mdsio options, to allow |
73 |
|
outputs of tiles+halos in debugging phases and in adjoint runs, |
74 |
|
and to allow some flexibility in tuning (adoint) I/O depending on each |
75 |
|
file system behavior. With regard to tuning, most of the potential knobs |
76 |
|
(to leave files open, to allocate the I/O indep. of usesinglecpuio, |
77 |
|
to specify directories, to specify the typical size of I/O calls, etc.) |
78 |
|
are not yet included, and will be added if they prove useful. |
79 |

80 |
|

81 |
|
o pkg/seaice: |
82 |
|
new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty |

84 |
|
code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined. |
