|
o cg2d: |
| 8 |
|
use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F : |
| 9 |
|
this reduces number of EXCH calls by 2 when using exch2. |
| 10 |
|
For now, keep previous size array for gc2d_nsa.F to avoid Pb with store |
| 11 |
|
directives and missing simple EXCH (exch_s3d_rx) adjoint code. |
| 12 |
|
o pkg/thsice: |
| 13 |
|
add code for Near Infra-Red albedo (from Jeff) |
| 14 |
|
(turned on with run-time flag: thSIce_calc_albNIR, in data.ice). |
| 15 |
|
o ini_model_io: |
| 16 |
|
move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F |
| 17 |
|
MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F |
| 18 |
|
to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice. |
| 19 |
|
|
| 20 |
|
checkpoint61s |
| 21 |
|
o pkg/exch2 (exch2_rxN_cube*): |
| 22 |
|
remove last BARRIER (no need to synchronise after getting data from shared |
| 23 |
|
buffer (get) as long as any change to buffer (put,recv) is between BARRIER) |
| 24 |
|
o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH |
| 25 |
|
and generate new output (for the 2 tests) using default rotationPeriod. |
| 26 |
|
o pkg/exch2: |
| 27 |
|
- always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F |
| 28 |
|
(was already the case with AUTODIFF_EXCH2 defined) |
| 29 |
|
- add bj in exch2 arrays and S/R. |
| 30 |
|
- can now use pkg/exch2 for regular (non CS) set-up; switch test experiment |
| 31 |
|
MLAdjust to exch2 (identical results except with MPI -> truncation diff); |
| 32 |
|
o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep |
| 33 |
|
- adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY |
| 34 |
|
GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT |
| 35 |
|
- verification experiment natl_box.longstep |
| 36 |
|
o build_options: ifort+mpi_aces optfile (following Constantinos advise): |
| 37 |
|
allow different versions of ifort (8 or 9) and different versions |
| 38 |
|
of mpi (mpich or mpich2) to be used with the same optfile. |
| 39 |
|
requires to load a netcdf module and set MPI_INC_DIR (see comments inside |
| 40 |
|
optfile). Change testing scripts (example_scripts/ACESgrid) accordingly. |
| 41 |
|
o pkg/seaice: |
| 42 |
|
fix previous modif (3-level field removed) for old-pickup reading |
| 43 |
|
|
| 44 |
|
checkpoint61r |
| 45 |
|
o pkg/seaice: |
| 46 |
|
- clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps: |
| 47 |
|
1. introduce fields for time step (N-1) |
| 48 |
|
2. do not use levels 2 and 3 anymore (but keep them) |
| 49 |
|
3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This |
| 50 |
|
includes changes to pkg/thsice/thsice_get_velocity.F, |
| 51 |
|
model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and |
| 52 |
|
pkg/obcs/obcs_apply_uvice.F. |
| 53 |
|
- completely remove code for leap-frog time stepping for second order |
| 54 |
|
advection |
| 55 |
|
- adjusted adjoint accordingly; |
| 56 |
|
gradient checks have improved by an order of magnitude! |
| 57 |
|
|
| 58 |
|
checkpoint61q |
| 59 |
|
o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver |
| 60 |
|
- the boundary conditions along open boundaries are unclear, because the |
| 61 |
|
associated masks are set to zero and are thus treated as closed when |
| 62 |
|
applying the slip-boundary conditions. |
| 63 |
|
- move initialisation of grid variables from seaice_init_varia to _fixed |
| 64 |
|
o adding doc/diags_changes.txt |
| 65 |
|
o model/src: |
| 66 |
|
do_the_model_io: rename few pkg S/R which are called from do_the_model_io, |
| 67 |
|
to avoid "_diags" naming if no relation to pkg/diagnostics. |
| 68 |
|
ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF |
| 69 |
|
file and only call PLOT_FIELD_XYZ if debugMode=T. |
| 70 |
|
remove few PLOT_FIELD_XY calls outside initialisation. |
| 71 |
|
remove few unnecessary BARRIER. |
| 72 |
o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling |
o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling |
| 73 |
of salt_plume package in Southern Ocean |
of salt_plume package in Southern Ocean |

heat flux, and atmospheric and oceanic ice growth |
