|
o CG2D: use pre-computed solver main-diagonal (stored in common block); |
| 8 |
|
this affects truncation error ; generate new output file for exp. which |
| 9 |
|
fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d), |
| 10 |
|
global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d), |
| 11 |
|
ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d), |
| 12 |
|
MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d), |
| 13 |
|
tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d), |
| 14 |
|
vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d) |
| 15 |
|
o start implementation of deep-atmosphere and anelastic formulation |
| 16 |
|
o verification: remove 2nd copy of input files and use script "prepare_run" |
| 17 |
|
to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M) |
| 18 |
|
o mom_common/vecinv/fluxform: fix a few initialisation isssues |
| 19 |
|
o profiles: fix for multithreaded case |
| 20 |
|
|
| 21 |
|
o diagnostics: rename few diags: |
| 22 |
|
s/'PRESSURE'/'RCENTER '/g |
| 23 |
|
s/'TICE '/'oceFreez'/g |
| 24 |
|
s/'TAUX '/'oceTAUX '/g |
| 25 |
|
s/'TAUY '/'oceTAUY '/g |
| 26 |
|
s/'SWFLUX '/'oceQsw '/g |
| 27 |
|
s/DIFx/DFxE/g |
| 28 |
|
s/DIFy/DFyE/g |
| 29 |
|
and add few ocean-forcing diagnostics: |
| 30 |
|
atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS |
| 31 |
|
o modifications to pkg/seaice/growth.F and budget.F, which change results of |
| 32 |
|
lab_sea experiment: HSNOW was sometimes treated as effective and sometimes |
| 33 |
|
as actual snow thickness. It now refers everywhere to effective snow |
| 34 |
|
thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA. |
| 35 |
|
|
| 36 |
|
checkpoint58r_post |
| 37 |
|
o modifications to pkg/seaice/growth.F, which change results of |
| 38 |
|
lab_sea experiment: fixes pertain to melting snow over open water, to |
| 39 |
|
masking EVAP under sea ice, and to using the correct AREA variable for |
| 40 |
|
computations of EVAP, PRECIP, HSNOW, and GHEFF |
| 41 |
|
o add ability to read bathy, salt, and theta using MNC (off by def) |
| 42 |
|
o add flooding algorithm and advection of HSNOW for pkg/seaice; |
| 43 |
|
both are turned off by default and do no change any results |
| 44 |
|
o seaice advection with pkg/thsice: a step toward the use of non-linear |
| 45 |
|
advection scheme, but #ifdef or commented out for now (requires more EXCH). |
| 46 |
|
o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens |
| 47 |
|
(identical results) and the standard version of EXTERNAL_FIELDS_LOAD |
| 48 |
|
in natl_box (affects results @ truncation level: update output.txt) |
| 49 |
|
o multi-threading and IO: |
| 50 |
|
- replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R. |
| 51 |
|
- remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls |
| 52 |
|
(needed to work with SingleCpuIO): tested in all verif. exp. |
| 53 |
|
o GAD: use simpler DST3 formulation as default (old version left within #ifdef) |
| 54 |
|
affects the results (but none of the verification test uses this scheme). |
| 55 |
|
o Adding some pkg/diagnostics capability to pkg/seaice |
| 56 |
|
(will certainly be subject to changes) |
| 57 |
|
o ctrl: adding new control variables: |
| 58 |
|
lwflux, lwdown, evap, snowprecip, apressure, runoff |
| 59 |
|
|
| 60 |
|
checkpoint58q_post |
| 61 |
|
o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE. Speeds up |
| 62 |
|
1/6-deg Southern Ocean configuration by 8% on IBM Datastar and |
| 63 |
|
high_res_cube configuration by 4% on Columbia. |
| 64 |
|
o clean-up multi-threaded problems (reported by debugger tcheck on ACES); |
| 65 |
|
add (in global_with_exf/code) a version of EXF_INTERP_READ without |
| 66 |
|
dynamical allocation (seems to work in multi-threaded). |
| 67 |
|
o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using |
| 68 |
|
single CPU io) so that TAF does not have to see EESUPPORT.h |
| 69 |
|
o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux) |
| 70 |
|
|
| 71 |
|
checkpoint58p_post |
| 72 |
|
o obcs: stop if obcs is used with useCDscheme = .true. |
| 73 |
|
o shelfice: |
| 74 |
|
- fix a sign error so that no slip at shelfice interface works |
| 75 |
|
- remove stop for combination non-hydrostatic code and shelfice. That does |
| 76 |
|
not mean, that the results are correct, but at least they are numerically |
| 77 |
|
stable |
| 78 |
|
o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted) |
| 79 |
|
o added adjoint exch routined for all exch*3d* routines |
| 80 |
|
and updated flow directives |
| 81 |
|
|
| 82 |
|
checkpoint58o_post |
| 83 |
|
o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ; |
| 84 |
|
remove old subroutines (_XY_ & _XYZ_); update the adjoint version. |
| 85 |
|
o change controling S/R for writing pickup file (new S/R do_write_pickup) |
| 86 |
|
and clean-up reading/writing of pickup files. |
| 87 |
|
o fix local version of read/write pickup (NH part) in rotating_tank/code |
| 88 |
|
o simplify EXCH interface: |
| 89 |
|
- change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list) |
| 90 |
|
- not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version |
| 91 |
|
o added the regrid package |
| 92 |
|
o shelfice: |
| 93 |
|
- add a simple boundary layer scheme to reduce noise |
| 94 |
|
- fix the indexing in shelfice_u/v_drag so that there will be actually drag |
| 95 |
|
|
| 96 |
|
checkpoint58n_post |
| 97 |
|
o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to |
| 98 |
|
local variable (not in common block). |
| 99 |
|
o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass. |
| 100 |
|
- still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more); |
| 101 |
|
- still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls |
| 102 |
|
to work with SingleCpuIO. |
| 103 |
|
o add "_d 0" to real constant of pkg/cfc subroutines ; |
| 104 |
|
update exp. cfc_exemple & tutorial_cfc_offline output files. |
| 105 |
|
o multi-threading and IO: |
| 106 |
|
- all threads call READ_FLD S/R (needed if using SingleCpuIO): |
| 107 |
|
(no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R. |
| 108 |
|
- barrier before and after reading. |
| 109 |
|
- stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE) |
| 110 |
|
- avoid using MDS_WRITELOCAL for LAND pkg output. |
| 111 |
|
- new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics |
| 112 |
|
common-block variables ; Allows multi-threading with master-thread IO. |
| 113 |
|
o change default MAX_NO_THREADS from 32 to 4 ; |
| 114 |
|
and stop cleanly when MAX_NO_THREADS is too small. |
| 115 |
|
o add S/R BAR_CHECK to check multi-threaded barrier synchronization |
| 116 |
|
|
| 117 |
|
checkpoint58m_post |
| 118 |
|
o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc. |
| 119 |
|
and side-drag) on CS-grid : global_ocean.cs32x15.viscA4 |
| 120 |
|
o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp. |
| 121 |
|
keep global_ocean.90x40x15 (for AD testing) with former secondary test |
| 122 |
|
(".qshyd") as the main test (mv output.qshyd.txt to output.txt) |
| 123 |
|
o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos; |
| 124 |
|
add MITgcm_tutorials (= code + all the tutorials) |
| 125 |
|
o ecco, option to compute cost for total ssh (mean+anom) |
| 126 |
|
o consistent with addition of ptracer and ssh in pkg/profiles |
| 127 |
|
o profiles: adding ptracer and ssh |
| 128 |
|
o testreport: change multi-test output-file name |
| 129 |
|
(from output.txt.{name} to output.{name}.txt) |
| 130 |
|
o profiles: now ok for mutli-tiles case |
| 131 |
|
o seaice: add 4 parameters for different advection schemes for area, |
| 132 |
|
(effective) seaice thickness, enthalphy, and snow height. Their default |
| 133 |
|
is the standard parameter SEAICEadvScheme |
| 134 |
|
o calc_gw: |
| 135 |
|
- add cosFacU in zonal viscous flux (harmonic.visc.). |
| 136 |
|
- put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt. |
| 137 |
|
of tutorial_plume_on_slope. |
| 138 |
|
o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria). |
| 139 |
|
o calc_gw: true flux-form, account for horizontal grid spacing. |
| 140 |
|
update rotating_tank results, but not plume_on_slope (affected at |
| 141 |
|
truncation level, 11 digits). |
| 142 |
|
|
| 143 |
|
checkpoint58l_post |
| 144 |
|
o calc_gw: |
| 145 |
|
- take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V |
| 146 |
|
- remove side-drag for now (need to fix it); update plume_on_slope results. |
| 147 |
|
- fix for partial-cell & non-uniform dz; update plume_on_slope results. |
| 148 |
|
o commit code to make SST/SSS weights spatially variable |
| 149 |
|
(based on either variable in-situ or variable initial T/S weights) |
| 150 |
|
o pkg/ecco: |
| 151 |
|
* commit code to relax deviations of xx_theta, xx_salt to 5*sigma, |
| 152 |
|
now based on horizontally varying weights wthetaLev, wsaltLev |
| 153 |
|
* cost_averagesflags now returns year indices in addition to day, month |
| 154 |
|
* sflux balance is performed on annual basis |
| 155 |
|
(sflxumm, sfluxmm2, bal_sfluxmm) |
| 156 |
|
* for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO, |
| 157 |
|
including separate counting and multipliers |
| 158 |
|
o pkg/rbcs |
| 159 |
|
* add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing |
| 160 |
|
|
| 161 |
|
checkpoint58k_post |
| 162 |
|
o testreport: |
| 163 |
|
- always build in dir. "build" (if not there, mkdir build instead of building |
| 164 |
|
& running in input) |
| 165 |
|
- run in dir run (if it exists), in build otherwise. |
| 166 |
|
- call prepare_run (if input/prepare_run exists) |
| 167 |
|
- run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists. |
| 168 |
|
o pkg/exf modifications to interpolation and rotation routines for more |
| 169 |
|
reasonable treatment of North Pole singularity: for tracers North Pole |
| 170 |
|
value is set to northernmost zonal-mean value, for zonal velocity it is |
| 171 |
|
set to zero, and for meridional velocity it is set to northernmost value. |
| 172 |
|
o pkg/exf/exf_check_range.F |
| 173 |
|
- add tile index to diagnostics and move stop statement to the very |
| 174 |
|
end of the routine. |
| 175 |
|
o pkg/diagnostics: (diagnostics_main_init.F) |
| 176 |
|
define title of isomorphic variables according to the current config. |
| 177 |
|
o pkg/thsice with pkg/seaice dynamics: |
| 178 |
|
- fix domain of computation (interior only, required for exf) and do exchanges |
| 179 |
|
- seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient |
| 180 |
|
o towards a standard way of dealing with multi-threading in MONITOR |
| 181 |
|
and ${PKG}_MONITOR (all except ptracers_monitor) subroutines. |
| 182 |
|
o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith) |
| 183 |
|
to W momentum equation in nonhydrostatic and quasihydrostatic runs. |
| 184 |
|
o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor. |
| 185 |
|
o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block) |
| 186 |
|
o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL |
| 187 |
|
(problems ? with gradient check in bottom_ctrl_5x5 adjoint test) |
| 188 |
|
o tracer advection: |
| 189 |
|
- clean-up and simplify calc_common_factors.F |
| 190 |
|
- make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer |
| 191 |
|
advection subroutine (but still not used within DST advection S/R) |
| 192 |
|
o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim) |
| 193 |
|
|
| 194 |
|
checkpoint58j_post |
| 195 |
|
o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields |
| 196 |
|
from file (collects calls previously in FORWARD_STEP) |
| 197 |
|
o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS |
| 198 |
|
o adjoint store dir. adjusted accordingly |
| 199 |
|
o genmake2 |
| 200 |
|
replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list. |
| 201 |
|
|
| 202 |
|
checkpoint58i_post |
| 203 |
|
o pkg/seaice: add parameter that allows to scale/turn off effect of seaice |
| 204 |
|
on wind stress (SEAICEstressFactor defaults to 1.) |
| 205 |
|
o Total number of Timers is finite (<=40): comment out 2 non-essential one |
| 206 |
|
in the_main_loop.F to avoid Pb (e.g., when running fizhi test) |
| 207 |
|
o vector_invariant: fix highOrderVorticity(=4.th.Order) advection |
| 208 |
|
on CS-grid: no longer loosing mass. |
| 209 |
|
o exf & curvilinear-grid: no longer modify longitude xC & xG. |
| 210 |
|
o pkg/ggl90: fix sloppy output and fix a bug |
| 211 |
|
o pkg/seaice: added SEAICEuseEVPpickup parameter |

| 225 |
|
|
| 226 |
|
checkpoint58g_post |
| 227 |

| 228 |
|
used for mean seasonal cycle, mean diurnal cycle); add an example |
| 229 |
|
in verification/global_ocean.cs32x15/input.thsice/data.diagnostics |
