|
o model/src: |
| 8 |
|
- in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F |
| 9 |
|
- main_do_loop.F: no longer includes additional (AUTODIFF) header files |
| 10 |
|
when using TAF but only if using OpenAD. |
| 11 |
|
o pkg/mom_common+fluxform+vecinv: |
| 12 |
|
- always set horiz. viscosity arrays to background value before calling |
| 13 |
|
MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC |
| 14 |
|
only when using variable horiz. viscosity (useVariableVisc=T); |
| 15 |
|
- simplify mom_vecinv.F (only 1 block for momViscosity). |
| 16 |
|
o pkg/mom_common: variable horiz. viscosity in NH code |
| 17 |
|
- move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F) |
| 18 |
|
from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h |
| 19 |
|
- store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc, |
| 20 |
|
useBiharmonicVisc & useVariableVisc. |
| 21 |
|
- fix old bug (already in 1rst implementation of variable horizontal viscosity |
| 22 |
|
in calc_gw.F, version 1.27, 2006/06/20): |
| 23 |
|
horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0 |
| 24 |
|
even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero. |
| 25 |
|
- change background horiz viscosity in vertical momentum (gW) to always be |
| 26 |
|
viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using |
| 27 |
|
any type of variable viscosity, e.g., viscAh/4Grid) |
| 28 |
|
- change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of |
| 29 |
|
viscAh,viscA4) which default to viscAh,viscA4 : this avoid missing |
| 30 |
|
horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since |
| 31 |
|
default viscAh,viscA4 is zero). |
| 32 |
|
o model/src: |
| 33 |
|
- extend length of drC & recip_drC from Nr to Nr+1. |
| 34 |
|
o Divided Adjoint (DIVA) with MPI: |
| 35 |
|
- genmake2: do not create local ./mpi_headers dir when no file to copy into. |
| 36 |
|
- remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT |
| 37 |
|
and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h. |
| 38 |
|
|
| 39 |
|
checkpoint64k (2013/07/23) |
| 40 |
|
o tools/OAD_support: |
| 41 |
|
- avoid the need for file "oadtempflile" in insertTemplateDir.bash |
| 42 |
|
and remove it from genmake2. |
| 43 |
|
o tools/build_options: |
| 44 |
|
- remove MPI_HEADER_FILES_INC setting (no longer used) and comment out |
| 45 |
|
MPI_HEADER_FILES list (let genmake2 find the missing headers) |
| 46 |
|
o verification/halfpipe_streamice: |
| 47 |
|
- change to driving stress formulation; update both Fwd & AD output. |
| 48 |
|
o tools/genmake2 and Divided Adjoint with MPI: |
| 49 |
|
- remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken); |
| 50 |
|
- only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set; |
| 51 |
|
- add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in |
| 52 |
|
Makefile, which is set by genmake2, and check which mpi-headers are needed. |
| 53 |
|
Note: need to update adjoint_options/adjoint_diva_mpi accordingly. |
| 54 |
|
- update target "CLEAN" (to also remove ./mpi_headers/ dir). |
| 55 |
|
o testreport: |
| 56 |
|
- changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present, |
| 57 |
|
perform additional runs (number of additional runs is "add_DIVA_runs" taken |
| 58 |
|
from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h"). |
| 59 |
|
o verification/lab_sea (AD test): |
| 60 |
|
- change to test Divided Adjoint Run in this set-up (both standard AD test |
| 61 |
|
and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test. |
| 62 |
|
o pkg atm_ & ocn_compon_interf: |
| 63 |
|
- remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old |
| 64 |
|
staggerTimeStep implementation) and disable (retired) corresponding |
| 65 |
|
parameter. |
| 66 |
|
o pkg/offline: |
| 67 |
|
- comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01]; |
| 68 |
|
- add S/R OFFLINE_CHECK to print offline parameter summary |
| 69 |
|
and stop if loading a file that is not used; |
| 70 |
|
- enable to calculate GMRedi tensor, KPP mixing and convective index |
| 71 |
|
when the corresponding file(s) is/are not specified (but pkg is used). |
| 72 |
|
- comment out resetting of monitorFreq (to endTime) since it still useful |
| 73 |
|
for monitoring CFL numbers and checking offline fields. |
| 74 |
|
o OpenAD: |
| 75 |
|
- do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get |
| 76 |
|
smaller standard output) and generate new (smaller) output (on baudelaire |
| 77 |
|
using gfortran with -ieee) for exp. tutorial_tracer_adjsens |
| 78 |
|
o model/src: |
| 79 |
|
- call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F), |
| 80 |
|
(where external_forcing_adjust was called) and change list of arguments; |
| 81 |
|
- merge external_forcing_adjust.F into external_forcing_surf.F |
| 82 |
|
- put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F) |
| 83 |
|
which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX, |
| 84 |
|
previously in file "balance_relax.F", now removed); remove corresponding |
| 85 |
|
arrays in FFIELDS.h. |
| 86 |
|
- EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement |
| 87 |
|
a hack for getting back surfaceForcingS (loaded from file) when using |
| 88 |
|
ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up. |
| 89 |
|
- update output of AD test experiment global_ocean.cs32x15.seaice_dynmix |
| 90 |
|
(was getting only 11 digits for AD-grad, due to different truncation |
| 91 |
|
error in AD code). |
| 92 |
|
|
| 93 |
|
checkpoint64j (2013/07/04) |
| 94 |
|
o pkg/offline: |
| 95 |
|
- to enable the use of other features with pkg offline (e.g., obcs), |
| 96 |
|
also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come. |
| 97 |
|
- comment out "allowFreezing" (now active) in 2 offline testing exp. |
| 98 |
|
o pkg/exf ALLOW_RUNOFTEMP |
| 99 |
|
- fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL |
| 100 |
|
- ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice |
| 101 |
|
- changes verification/global_ocean.cs32x15/results/output.seaice.txt |
| 102 |
|
o pkg/atm_phys: |
| 103 |
|
- allows to add some damping on uVel,vVel (strength only function of k). |
| 104 |
|
o verification, ad-tests: |
| 105 |
|
- reduce length of the simulation for AD test: global_ocean.cs32x15.seaice, |
| 106 |
|
global_ocean_ebm and offline_exf_seaice.thsice. |
| 107 |
|
o verification/halfpipe_streamice: |
| 108 |
|
- found a bug in s/r pkg/streamice/streamice_advect_thickness which caused |
| 109 |
|
flux input boundary conditions to be ignored; a fix for this bug changed |
| 110 |
|
verification results for forward test. |
| 111 |
|
- add adjoint test. |
| 112 |
|
o pkg/ptracers: |
| 113 |
|
- allow to restart without SOM pickup (resetting SOM to zero). |
| 114 |
|
o pkg/gmredi: |
| 115 |
|
- New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added. |
| 116 |
|
- It uses mixing length theory and suppression by steering level effects to |
| 117 |
|
calculate a diffusivity used in the Redi tensor (see Bates et al., submitted |
| 118 |
|
to JPO, for more details). |
| 119 |
|
- It also uses the diffusivity to calculate an eddy induced streamfunction |
| 120 |
|
based on a PV closure (rather than a buoyancy closure as in GM). |
| 121 |
|
- New files added to pkg/gmredi: |
| 122 |
|
gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy |
| 123 |
|
induced overturning streamfunction (called from gmredi_calc_tensor) |
| 124 |
|
gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required |
| 125 |
|
for use in gmredi_k3d |
| 126 |
|
gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate |
| 127 |
|
the eddy diffusivity |
| 128 |
|
|
| 129 |
|
checkpoint64i (2013/06/18) |
| 130 |
|
o pkg/cheapaml: |
| 131 |
|
- take src files from MITgcm_contrib/verification_other/offline_cheapaml/code |
| 132 |
|
that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics) |
| 133 |
|
with pkg/cheapaml. |
| 134 |
|
o utils/python: add subpackage for cubed sphere function, first example is |
| 135 |
|
simple cs.pcol to plot 2D fields on a map |
| 136 |
