|
o fix multi-category seaice: |
| 8 |
|
- change cpp flag SEAICE_MULTILEVEL to more meaningful name: |
| 9 |
|
SEAICE_MULTICATEGORY |
| 10 |
|
- fix short wave heat flux |
| 11 |
|
o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics |
| 12 |
|
and allow to use EVP solver. Change forward lab_sea: test both EVP |
| 13 |
|
solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint) |
| 14 |
|
o Initial check-in of lab_sea adjoint |
| 15 |
|
(very similar to natl_box_adjoint/code_seaice) |
| 16 |
|
* used C-grid and EVP solver |
| 17 |
|
* used KPP, GM/Redi |
| 18 |
|
* uses inAdExact=.TRUE. |
| 19 |
|
* gradient checks fail for both ADM and TLM |
| 20 |
|
due to sensitive snow melt code in seaice_grwoth (look for "JZ") |
| 21 |
|
f.d. gradients actually seem more problematic than ADM, TLM gradients; |
| 22 |
|
issue is related to forward mismatch between g77 an ifort |
| 23 |
|
o pkg/seaice: overhaul of thermodynamics |
| 24 |
|
- growth.F and groatb.F are replaced by new routine seaice_growth.F |
| 25 |
|
- budget.F is replaced by two new routines seaice_budget_ocean/ice.F |
| 26 |
|
- move a few global fields out of SEAICE.h into seaice_growth.F and |
| 27 |
|
make them 2D (FICE/QNETO/ ...) |
| 28 |
|
- remove FO (it is the same as QNETO) |
| 29 |
|
- introduce a few local fields to avoid modifying external fields such |
| 30 |
|
as atemp, etc. |
| 31 |
|
|
| 32 |
|
checkpoint58s_post |
| 33 |
|
o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F |
| 34 |
|
changed exf_set_gen.F so that |
| 35 |
|
genperiod=0 means input file is one time-constant field and |
| 36 |
|
genperiod=-12 means input file contains 12 monthly means |
| 37 |
|
o CG2D: use pre-computed solver main-diagonal (stored in common block); |
| 38 |
|
this affects truncation error ; generate new output file for exp. which |
| 39 |
|
fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d), |
| 40 |
|
global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d), |
| 41 |
|
ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d), |
| 42 |
|
MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d), |
| 43 |
|
tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d), |
| 44 |
|
vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d) |
| 45 |
|
o start implementation of deep-atmosphere and anelastic formulation |
| 46 |
|
o verification: remove 2nd copy of input files and use script "prepare_run" |
| 47 |
|
to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M) |
| 48 |
|
o mom_common/vecinv/fluxform: fix a few initialisation isssues |
| 49 |
|
o profiles: fix for multithreaded case |
| 50 |
|
|
| 51 |
|
o diagnostics: rename few diags: |
| 52 |
|
s/'PRESSURE'/'RCENTER '/g |
| 53 |
|
s/'TICE '/'oceFreez'/g |
| 54 |
|
s/'TAUX '/'oceTAUX '/g |
| 55 |
|
s/'TAUY '/'oceTAUY '/g |
| 56 |
|
s/'SWFLUX '/'oceQsw '/g |
| 57 |
|
s/DIFx/DFxE/g |
| 58 |
|
s/DIFy/DFyE/g |
| 59 |
|
and add few ocean-forcing diagnostics: |
| 60 |
|
atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS |
| 61 |
|
o modifications to pkg/seaice/growth.F and budget.F, which change results of |
| 62 |
|
lab_sea experiment: HSNOW was sometimes treated as effective and sometimes |
| 63 |
|
as actual snow thickness. It now refers everywhere to effective snow |
| 64 |
|
thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA. |
| 65 |
|
|
| 66 |
|
checkpoint58r_post |
| 67 |
|
o modifications to pkg/seaice/growth.F, which change results of |
| 68 |
|
lab_sea experiment: fixes pertain to melting snow over open water, to |
| 69 |
|
masking EVAP under sea ice, and to using the correct AREA variable for |
| 70 |
|
computations of EVAP, PRECIP, HSNOW, and GHEFF |
| 71 |
|
o add ability to read bathy, salt, and theta using MNC (off by def) |
| 72 |
|
o add flooding algorithm and advection of HSNOW for pkg/seaice; |
| 73 |
|
both are turned off by default and do no change any results |
| 74 |
|
o seaice advection with pkg/thsice: a step toward the use of non-linear |
| 75 |
|
advection scheme, but #ifdef or commented out for now (requires more EXCH). |
| 76 |
|
o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens |
| 77 |
|
(identical results) and the standard version of EXTERNAL_FIELDS_LOAD |
| 78 |
|
in natl_box (affects results @ truncation level: update output.txt) |
| 79 |
|
o multi-threading and IO: |
| 80 |
|
- replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R. |
| 81 |
|
- remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls |
| 82 |
|
(needed to work with SingleCpuIO): tested in all verif. exp. |
| 83 |
|
o GAD: use simpler DST3 formulation as default (old version left within #ifdef) |
| 84 |
|
affects the results (but none of the verification test uses this scheme). |
| 85 |
|
o Adding some pkg/diagnostics capability to pkg/seaice |
| 86 |
|
(will certainly be subject to changes) |
| 87 |
|
o ctrl: adding new control variables: |
| 88 |
|
lwflux, lwdown, evap, snowprecip, apressure, runoff |
| 89 |
|
|
| 90 |
|
checkpoint58q_post |
| 91 |
|
o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE. Speeds up |
| 92 |
|
1/6-deg Southern Ocean configuration by 8% on IBM Datastar and |
| 93 |
|
high_res_cube configuration by 4% on Columbia. |
| 94 |
|
o clean-up multi-threaded problems (reported by debugger tcheck on ACES); |
| 95 |
|
add (in global_with_exf/code) a version of EXF_INTERP_READ without |
| 96 |
|
dynamical allocation (seems to work in multi-threaded). |
| 97 |
|
o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using |
| 98 |
|
single CPU io) so that TAF does not have to see EESUPPORT.h |
| 99 |
|
o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux) |
| 100 |
|
|
| 101 |
|
checkpoint58p_post |
| 102 |
|
o obcs: stop if obcs is used with useCDscheme = .true. |
| 103 |
|
o shelfice: |
| 104 |
|
- fix a sign error so that no slip at shelfice interface works |
| 105 |
|
- remove stop for combination non-hydrostatic code and shelfice. That does |
| 106 |
|
not mean, that the results are correct, but at least they are numerically |
| 107 |
|
stable |
| 108 |
|
o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted) |
| 109 |
|
o added adjoint exch routined for all exch*3d* routines |
| 110 |
|
and updated flow directives |
| 111 |
|
|
| 112 |
|
checkpoint58o_post |
| 113 |
|
o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ; |
| 114 |
|
remove old subroutines (_XY_ & _XYZ_); update the adjoint version. |
| 115 |
|
o change controling S/R for writing pickup file (new S/R do_write_pickup) |
| 116 |
|
and clean-up reading/writing of pickup files. |
| 117 |
|
o fix local version of read/write pickup (NH part) in rotating_tank/code |
| 118 |
|
o simplify EXCH interface: |
| 119 |
|
- change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list) |
| 120 |
|
- not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version |
| 121 |
|
o added the regrid package |
| 122 |
|
o shelfice: |
| 123 |
|
- add a simple boundary layer scheme to reduce noise |
| 124 |
|
- fix the indexing in shelfice_u/v_drag so that there will be actually drag |
| 125 |
|
|
| 126 |
|
checkpoint58n_post |
| 127 |
|
o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to |
| 128 |
|
local variable (not in common block). |
| 129 |
|
o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass. |
| 130 |
|
- still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more); |
| 131 |
|
- still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls |
| 132 |
|
to work with SingleCpuIO. |
| 133 |
|
o add "_d 0" to real constant of pkg/cfc subroutines ; |
| 134 |
|
update exp. cfc_exemple & tutorial_cfc_offline output files. |
| 135 |
|
o multi-threading and IO: |
| 136 |
|
- all threads call READ_FLD S/R (needed if using SingleCpuIO): |
| 137 |
|
(no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R. |
| 138 |
|
- barrier before and after reading. |
| 139 |
|
- stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE) |
| 140 |
|
- avoid using MDS_WRITELOCAL for LAND pkg output. |
| 141 |
|
- new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics |
| 142 |
|
common-block variables ; Allows multi-threading with master-thread IO. |
| 143 |
|
o change default MAX_NO_THREADS from 32 to 4 ; |
| 144 |
|
and stop cleanly when MAX_NO_THREADS is too small. |
| 145 |
|
o add S/R BAR_CHECK to check multi-threaded barrier synchronization |
| 146 |
|
|
| 147 |
|
checkpoint58m_post |
| 148 |
|
o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc. |
| 149 |
|
and side-drag) on CS-grid : global_ocean.cs32x15.viscA4 |
| 150 |
|
o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp. |
| 151 |
|
keep global_ocean.90x40x15 (for AD testing) with former secondary test |
| 152 |
|
(".qshyd") as the main test (mv output.qshyd.txt to output.txt) |
| 153 |
|
o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos; |
| 154 |
|
add MITgcm_tutorials (= code + all the tutorials) |
| 155 |
|
o ecco, option to compute cost for total ssh (mean+anom) |
| 156 |
|
o consistent with addition of ptracer and ssh in pkg/profiles |
| 157 |
|
o profiles: adding ptracer and ssh |
| 158 |
|
o testreport: change multi-test output-file name |
| 159 |
|
(from output.txt.{name} to output.{name}.txt) |
| 160 |
|
o profiles: now ok for mutli-tiles case |
| 161 |
o seaice: add 4 parameters for different advection schemes for area, |
o seaice: add 4 parameters for different advection schemes for area, |
| 162 |
