|
o exch2: |
| 8 |
|
change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS) |
| 9 |
|
- no longer depend on the order sequence (N,S,E,W). |
| 10 |
|
- 3rd exchange no longer needed (tested with 24 tiles). |
| 11 |
|
- same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff) |
| 12 |
|
- exch_UV_A-grid readily available (but not yet tested). |
| 13 |
|
comment out 3rd exch call and remove copy of V to U at SE & NE face-corners |
| 14 |
|
(both are no longer needed) in exch_uv: no effect in forward run; but |
| 15 |
|
get truncation error differences with adjoint exch. |
| 16 |
|
o exch2: |
| 17 |
|
- change index-bounds storage (moved from target to local tile, |
| 18 |
|
more intuitive this way) ; rename/remove some variables. |
| 19 |
|
- change utils/exch2/matlab-topology-generator & code_mods accordingly. |
| 20 |
|
|
| 21 |
|
checkpoint61a |
| 22 |
|
o exch2/matlab-topology-generator: |
| 23 |
|
fix bug in index bounds for N-S internal exchange (hard to tell if this |
| 24 |
|
had any effect on the solution). |
| 25 |
|
o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf |
| 26 |
|
is exceeded |
| 27 |
|
o testreport: modify syntax of awk, so that it works also with |
| 28 |
|
awk, and not only with nawk and gawk |
| 29 |
|
|
| 30 |
|
checkpoint61 |
| 31 |
|
o autodiff |
| 32 |
|
Change default for TAF usage by removing argument '-nonew_arg' |
| 33 |
|
This changes TAF subroutine argument list (ordering of active var.) |
| 34 |
|
Omission of this flag leads to incompatibility w.r.t. TAMC |
| 35 |
|
To restore TAMC-compatibility, need following modifs: |
| 36 |
|
* use adoptfile tools/adjoint_options/adjoint_tamc_compatibility |
| 37 |
|
* use CPP option #define AUTODIFF_TAMC_COMPATIBILITY |
| 38 |
|
Tested TAF version is 1.9.22 |
| 39 |
|
N.B.: exch2 hand-written adjoint code currently not TAMC compatible |
| 40 |
|
|
| 41 |
|
checkpoint60 |
| 42 |
|
--->>> This is the last checkpoint for which generating the adjoint |
| 43 |
|
--->>> is done via the TAMC-compatibility TAF-flag "-nonewarg" |
| 44 |
|
--->>> by default. |
| 45 |
|
--->>> Future checkpoints will ommit this flag by default. |
| 46 |
|
o pkg/generic_advdiff, os7mp: simplify and avoid division by zero. |
| 47 |
|
o pkg/grdchk: Add gradient check to etan0 perturbations. |
| 48 |
|
o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK). |
| 49 |
|
o pkg/autodiff: more flexibility in zeroadj. |
| 50 |
|
model/src: modifying do_oceanic_phys.F accordingly. |
| 51 |
|
o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation. |
| 52 |
|
o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option |
| 53 |
|
special setup of gmredi for which the adjoint is stable |
| 54 |
|
enough for parameter optimization. |
| 55 |
|
o bridging the gap between eddy stress and GM. |
| 56 |
|
-> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi) |
| 57 |
|
along with a change in CPP option (now ALLOW_EDDYPSI). |
| 58 |
|
-> when using GM w/ GM_AdvForm: |
| 59 |
|
The total eddy streamfunction (Psi = eddyPsi + K x Slope) |
| 60 |
|
is applied either in the tracer Eq. or in momentum Eq. |
| 61 |
|
depending on data.gmredi (intro. GM_InMomAsStress). |
| 62 |
|
-> ALLOW_EDDYPSI_CONTROL for estimation purpose. |
| 63 |
|
The key modifications are in model/src/taueddy_external_forcing.F |
| 64 |
|
pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F |
| 65 |
|
|
| 66 |
|
checkpoint59r |
| 67 |
|
o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array |
| 68 |
|
from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F); |
| 69 |
|
fix option to read coriolis(@ cell-corner) from files with CS-grid. |
| 70 |
|
o pkg/mnc: add some attributes to standard 1D-coordinate variables |
| 71 |
|
o pkg/diagnostics: enforce missing_value attribute for scalar variables at |
| 72 |
|
mass points, when using mnc for output |
| 73 |
|
- add runtime parameter (missing_value, missing_value_int) to override |
| 74 |
|
default (which is the value of getcon('UNDEF')) |
| 75 |
|
o pkg/mnc: prepare mnc for the actual use of missing values with the |
| 76 |
|
diagnostics package: small fix in mnc_cw_readwrite.template and more |
| 77 |
|
initialisation of never used fields |
| 78 |
|
- replace mnc_common.h and mnc_id_header.h with corresponding upper case |
| 79 |
|
versions |
| 80 |
|
o pkg/thsice/thsice_ini_vars.F added default initial values so that |
| 81 |
|
thermodynamics sea ice solver does not blow up when some initial fields |
| 82 |
|
are missing. |
| 83 |
|
o move from external_forcing_surf.F to ini_forcing.F |
| 84 |
|
the p-coord. hack consisting in using pLoad to set phi0surf ; |
| 85 |
|
update output of tutorial_global_oce_in_p (affected @ truncation level). |
| 86 |
|
o Freshen up a bit hs94.1x64x5, notably: |
| 87 |
|
remove rotationPeriod and tRef=5*0. (adjoint only), and add |
| 88 |
|
exactConserv=.TRUE. |
| 89 |
|
o pkg/generic_advdiff: |
| 90 |
|
change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only |
| 91 |
|
applies to files where Temperature & Salinity 2nd Order moments are used. |
| 92 |
o pkg/ptracers: add second-order moment advection schemes (80 and 81); |
o pkg/ptracers: add second-order moment advection schemes (80 and 81); |
| 93 |
this uses a dynamically allocated internal state data structure |
