|
o isomip experiment: |
| 8 |
|
- test pkg/shelfice with Non-Lin Free-Surf in one of the FWD set-up |
| 9 |
|
(input.htd) and update the output. |
| 10 |
|
o cd_code experiments: |
| 11 |
|
- use default cd_code options (#undef CD_CODE_NO_AB_MOMENTUM & |
| 12 |
|
#undef CD_CODE_NO_AB_CORIOLIS) in experiments: cfc_example (fwd) |
| 13 |
|
global_ocean.90x40x15 (ad & oad) and OpenAD (ad & oad) and |
| 14 |
|
update the corresponding output. |
| 15 |
|
o pkg/seaice: |
| 16 |
|
- reduce the number of include files and store directives in |
| 17 |
|
S/R seaice_lsr_tridiagu/v |
| 18 |
|
- change the order of loops in one case in S/R seaice_lsr_tridiagv |
| 19 |
|
(only for SEAICE_VECTORIZE_LSR_ZEBRA defined), which allows me to |
| 20 |
|
get rid off one store directive (a TAF bug?) |
| 21 |
|
- add one more instance of ifdef SEAICE_VECTORIZE_LSR_ZEBRA in |
| 22 |
|
S/R seaice_lsr_tridiagv to change the loop range for consistency |
| 23 |
|
- remove ilcall, m from parameter list of S/R seaice_lsr_tridiagu/v |
| 24 |
|
- fix a bug that affects the JFNK solver: replace sNx/y by i/jMax in |
| 25 |
|
S/R seaice_lsr_tridiagu/v (requires update of |
| 26 |
|
offline_exf_seaice/input.dyn_jfnk) |
| 27 |
|
|
| 28 |
|
checkpoint65a (2014/07/27) |
| 29 |
|
o model/src: |
| 30 |
|
- Non-Lin Free-Surf in p/z coords: allows hFacW,S to be larger than |
| 31 |
|
surrounding hFacC=1 @ edge of a step with different kSurfC on either side |
| 32 |
|
(topo in p-coords, ice-shelf in z-coords); update output of experiments |
| 33 |
|
tutorial_global_oce_in_p and isomip (both AD and OpenAD output). |
| 34 |
|
o model/src: |
| 35 |
|
- collect momentum forcing tendency into local 2-D array (passed as argument |
| 36 |
|
to apply_forcing S/R); this simplifies mom. Forcing diagnostics and CD_CODE |
| 37 |
|
parts in timestep.F (without CD_CODE_NO_AB_MOMENTUM defined = the default); |
| 38 |
|
affects results at machine truncation level (e.g., if using OBCS_SPONGE). |
| 39 |
|
- collect T & S forcing tendency into local 2-D array (passed as argument to |
| 40 |
|
apply_forcing S/R); add 3-D diagnostics for temp & salt forcing tendency. |
| 41 |
|
affects results at machine truncation level (e.g., ocean: if using |
| 42 |
|
SHORTWAVE_HEATING and atmos:, if using FrictionHeating or (atm_Rq<>0) |
| 43 |
|
moist correction due to vertical advection). |
| 44 |
|
- update output of experiments: fizhi-cs-32x32x40 (13 digits), |
| 45 |
|
global_ocean.cs32x15 (fwd: icedyn, seaice, thsice, all 3 @ 11d; adm & tml: |
| 46 |
|
seaice_dynmix & thsice, fwd grd @ 3 & 8), hs94.1x64x5 (ad grd @ 13), |
| 47 |
|
obcs_ctrl (ad & fwd grd @ 12 & 7). |
| 48 |
|
o pkg/ptracers & diagnostics: |
| 49 |
|
- use ptracers (short) name (instead of long one) to make ptracers diagnostics |
| 50 |
|
title (to avoid some unexpected truncation); sort out ptracers diags units. |
| 51 |
|
- collect ptracer forcing tendency into local 2-D array (passed as argument |
| 52 |
|
to apply_forcing S/R); add 3-D diagnostics for ptracers forcing tendency. |
| 53 |
|
|
| 54 |
|
checkpoint65 (2014/07/18) |
| 55 |
|
o pkg/fizhi: |
| 56 |
|
- add parenthesis around fizhi tendencies in fizhi_tendency_apply.F: this |
| 57 |
|
affects results at machine truncation level. Update output of experiments |
| 58 |
|
fizhi-cs-32x32x40 (12 digits for cg2d) & fizhi-cs-aqualev20 (13 digits). |
| 59 |
|
o pkg/seaice: more clean up |
| 60 |
|
- rename TAF common block tapes to be more consistent and remove |
| 61 |
|
unnecessary duplicates |
| 62 |
|
- add store directives to remove more recomputations, but use smaller |
| 63 |
|
tapes (and adjust keys) when SEAICE_LSR_ADJOINT_ITER is undefined. |
| 64 |
|
The idea behind this flag is to reduce the memory footprint when the |
| 65 |
|
adjoint of the LSR is not required. As of now, defining the flag |
| 66 |
|
SEAICE_LSR_ADJOINT_ITER increases 4 common block tapes for 2D field by |
| 67 |
|
a factor of SOLV_MAX_FIXED (=500 by default in SEAICE_SIZE.h). |
| 68 |
|
For experiment offline_exf_seaice, this means on a linux box with gfortran |
| 69 |
|
nearly a factor of 10 (but keep in mind there is mostly seaice code in |
| 70 |
|
this experiment): |
| 71 |
|
> size mitgcmuv_ad |
| 72 |
|
text data bss dec hex |
| 73 |
|
5100659 1216 220458952 225560827 d71c8fb |
| 74 |
|
5339425 1200 1868783272 1874123897 6fb4dc79 (SEAICE_LSR_ADJOINT_ITER) |
| 75 |
|
but only a moderate increase of 36% for global_ocean.cs32x15: |
| 76 |
|
text data bss dec hex |
| 77 |
|
6695027 1648 1014578664 1021275339 3cdf6ccb |

|
6695203 1648 1382505320 1389202171 52cd8afb (SEAICE_LSR_ADJOINT_ITER) |
| 79 |
|
- note: there are still recomputations in global_ocean.cs32x15 and |
| 80 |
|
offline_exf_seaice and the gradient agreement changes (gets a |
| 81 |
|
little worse) for global_ocean.cs32x15 (-> update output_adm.seaice.txt) |
| 82 |
|
- in general, the AD gradients still are wrong |
| 83 |
|
o OpenAD |
| 84 |
|
- clean up code_oad/ directories somewhat by moving files |
| 85 |
|
dontCompile, dontTransform, keepOriginal to OAD_support/ |
| 86 |
|
o model/src: |
| 87 |
|
- using MOM fluxform and Non-Lin Free-Surf with momDissip_In_AB=F |
| 88 |
|
(not currently tested): add dissipation terms before NLFS rescaling of |
| 89 |
|
tendencies (previously done after). |
| 90 |
|
o pkg/diagnostics: |
| 91 |
|
- write stats-diags in ascii file with more digits (same as in monitor). |
| 92 |
|
o pkg/down_slope: |
| 93 |
|
- drop the bi,bj dimension of argument recip_hFac in S/R DWNSLP_APPLY; with |
| 94 |
|
NLFS (not tested), use new recip_hFac value in order to conserve tracer. |
| 95 |
|
o model/src: |
| 96 |
|
- new file "apply_forcing.F" containing all the code previously in |
| 97 |
|
external_forcing.F, but with new argument list: pass, as new argument, |
| 98 |
|
the current level tendency array to update (instead of a direct update |
| 99 |
|
of the common bloc array). Change the corresponding calls. |
| 100 |
|
- add CPP option USE_OLD_EXTERNAL_FORCING (default is undef) to use |
| 101 |
|
EXTERNAL_FORCING_U,V,T,S subroutines (for backward compatibility). |
| 102 |
|
o pkg/seaice/seaice_lsr, a little bit of clean up |
| 103 |
|
- rearrange some code blocks, so that now all calculations for |
| 104 |
|
setting up the right-hand-sides done within one single block |
| 105 |
|
(I find that easier to read and understand) |
| 106 |
|
- rearrange freedrift-code to reduce the number of ifdefs |
| 107 |
|
- adjust some indentations and comments |
| 108 |
|
|
| 109 |
|
checkpoint64z (2014/07/10) |
| 110 |
|
o model/src and several pkgs: |
| 111 |
|
- change argument list of all S/R called from external_forcing.F and |
| 112 |
|
called from ptracers_forcing.F (renamed to ptracers_apply_forcing.F) |
| 113 |
|
to pass, as argument, the current level tendency array to update |
| 114 |
|
(instead of a direct update of the common bloc array). |
| 115 |
|
- change also (in the same way) argument list of PTRACERS_APPLY_FORCING; |
| 116 |
|
- rename taueddy_external_forcing.f to taueddy_tendency_apply.F |
| 117 |
|
o pkg/seaice/seaice_lsr.F |
| 118 |
|
- always initialize local arrays in seaice_lsr_tridiagu/v |
| 119 |
|
- add more local tapes to seaice_lsr_tridiagu/v |
| 120 |
|
- move storing u/vice(:,:,bi,bj) out of seaice_lsr_tridiagu/v, but |
| 121 |
|
keep it in bi/bj loop; this seems to be essential |
| 122 |
|
- gradients are still wrong but only by 4-7 orders of magnitude |
| 123 |
|
instead of 15 orders of magnitude, lab_sea improves a little |
| 124 |
|
o pkg/seaice |
| 125 |
|
- (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that |
| 126 |
|
generates unnecessary code in seaice_lsr_ad |
| 127 |
|
- add more store directives in seaice_lsr to avoid unnecessary code |
| 128 |
|
in seaice_lsr_ad |
| 129 |
|
- exclude some residual computations in seaice_lsr when |
| 130 |
|
ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code |
| 131 |
|
in seaice_lsr_ad |
| 132 |
|
- add more storing, a new tape (model/src/the_main_loop.F) and |
| 133 |
|
another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey |
| 134 |
|
and klockey should be checked by a specialist) |
| 135 |
|
- modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER ) |
| 136 |
|
and update lab_sea after previous changes in pkg/seaice below |
| 137 |
|
o pkg/autodiff: |
| 138 |
|
- introduce useSmoothCorrel2DinAdMode, SEAICEapproxLevInAd, and |
| 139 |
|
viscFacInAd : run time parameters allowing for adjoint switches |
| 140 |
|
note : logic for useSmoothCorrel2DinAdMode is in ctrl_readparms.F |
| 141 |
|
o pkg/ecco: |
| 142 |
|
- introduce cost_gencost_boxmean.F that computes a box mean |
| 143 |
|
temperature (for use in adjoint sensitivity studies). |
| 144 |
|
o model/src/set_defaults.F : initialize viscFacAdj to 1. |
| 145 |
|
o pkg/mom_common/mom_calc_visc.F: |
| 146 |
|
- ifdef ALLOW_AUTODIFF then include viscFacAdj factor. |
| 147 |
|
o pkg/seaice/seaice_summary.F: |
| 148 |
|
- statement for SEAICEadjMODE now in autodiff_readparms.F |
| 149 |
|
o pkg/seaice: |
| 150 |
|
- remove some store directives and add new ones in an effort to get |
| 151 |
|
finally rid off the recomputation warnings. This is successful |
| 152 |
|
when SEAICE_VECTORIZE_LSR ***and*** SEAICE_LSR_ADJOINT_ITER are |
| 153 |
|
defined (i.e. no extensive recomputation warnings left), but there |
| 154 |
|
are still too many recomputations on the solver iteration level |
| 155 |
|
- define SEAICE_VECTORISZE_LSR in offline_exf_seaice/code_ad/SEAICE_OPTIONS.h |
| 156 |
|
- move definition of MPSEUDOTIMESTEPS into TAMC-block in |
| 157 |
|
SEAICE_SIZE.h |
| 158 |
|
- add a store directive in S/R seaice_calc_viscosities |
| 159 |
|
o pkg/seaice (ITD code): |
| 160 |
|
- fix definition of Hlimit for multi-threaded case |
| 161 |
|
- use double precision arithmetic to compute Hlimit: this affects results; |
| 162 |
|
update output of experiment seaice_itd. |
| 163 |
|
o replace content of verification/seaice_itd |
| 164 |
|
- instead of a 1D column use the configuration of offline_exf_seaice |
| 165 |
|
to test the ice thickness distribution code with ridging |
| 166 |
|
- this is a first shot at this experiment |
| 167 |
|
- change of some defaults of ridging parameters SEAICEhStar (from |
| 168 |
|
100 to 25) and SEAICEmuRidging (from 5 to 3) in seaice_readparms.F |
| 169 |
|
and lot of new comments. |
| 170 |
|
|
| 171 |
|
checkpoint64y (2014/06/20) |
| 172 |
|
o pkg/seaice/seaice_reg_ridge.F: |
| 173 |
|
- modify the regularization of very small volumes of ice; only check |
| 174 |
|
total volume HEFF, and do not apply correction to individual ice |
| 175 |
|
classes because that leads to funny patterns in the heat and fw-fluxes |
| 176 |
|
into the ocean. Adjust seaice_itd/results/output.txt |
| 177 |
|
- replace nITD by SEAICE_multDim in loop-ranges |
| 178 |
|
o pkg/exf: |
| 179 |
|
- add code to process the case field period = -12. with UV interpolation. |
| 180 |
|
- move debug print (formerly active when exf_verbose=T) from EXF_getFFieldRec |
| 181 |
|
into S/R that calls it (i.e., exf_set_gen.F, exf_set_uv.F & obcs_exf_load.F) |
| 182 |
|
o verification/global_with_exf: |
| 183 |
|
- switch all fields period to -12. (was previously untested) in input/data.exf |
| 184 |
|
(but keep secondary test ".yearly" unchanged); update the reference output. |
| 185 |
|
o pkg/cal: |
| 186 |
|
- new calendar type "noLeapYear" for 365 days calendar without any leap year. |
| 187 |
|
o pkg/exf: |
| 188 |
|
- new integer parameter "exf_debugLev" (default set to main model debugLevel) |
| 189 |
|
to replace logical switch "exf_verbose" |
| 190 |
|
- report in STDOUT when loading a new record (if exf_debugLev >= 3) |
| 191 |
|
o pkg/sbo: |
| 192 |
|
- update from Katherine Quinn: evaluate mass directly from density and SSH |
| 193 |
|
(budget using Finite Volume method) instead of from bottom pressure. |
| 194 |
|
- allow testreport to collect few selected SBO output ; tested in exp. |
| 195 |
|
global_ocean.90x40x15 (after updating the results, to include SBO output). |
| 196 |
|
- fix some multi-threading issues (in output part). |
| 197 |
|
o model/src & most packages: |
| 198 |
|
- always call {PKG}_READPARMS even if corresponding use{PKG}=F; |
| 199 |
|
- in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R |
| 200 |
|
PACKAGES_UNUSED_MSG to print a weak warning when parameter file |
| 201 |
|
"data.{pkg}" exist ; and leave the S/R (return) just after. |
| 202 |
|
- more standard LAND pkg interface (land_init_fixed.F, land_check.F). |
| 203 |
|
+ call LAND_READPARMS from packages_readparms.F |
| 204 |
|
o pkg/seaice: |
| 205 |
|
- remove code that resets useThSice in S/R seaice_readparms and |
| 206 |
|
replace it by a warning in S/R seaice_check |
| 207 |
|
- remove parameter MULTDIM, replace with nITD and runtime |
| 208 |
|
parameter SEAICE_multDim (still hard-wired to nITD if |
| 209 |
|
SEAICE_ITD is defined) |
| 210 |
|
|
| 211 |
|
checkpoint64x (2014/05/24) |
| 212 |
|
o verification/lab_sea: |
| 213 |
|
- update adjoint and TLM output following changes to pkg/salt_plume |
| 214 |
|
- un-do the update after putting back local recip_Cp in few places. |
| 215 |
|
o pkg/salt_plume: modifications by An Nguyen: |
| 216 |
|
- add capability to do brine rejection (salt-plume) as function of |
| 217 |
|
volume+tracers (instead of only salinity tracer). |
| 218 |
|
- conserve volume by exchanging volume from each kLev to above to |
| 219 |
|
accommodate in-coming brine volume |
| 220 |
|
- store surface and klev exchanged fraction + volume in 4 new 3-d arrays |
| 221 |
|
- switch KPP surf buoyancy due to brine forcing to 3-d |
| 222 |
|
(3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume) |
| 223 |
|
- add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t |
| 224 |
|
- unrelatedly, also add ad-hoc capability to vary salt_plume scheme |
| 225 |
|
in East/West Arctic. |
| 226 |
|
o pkg/sbo: |
| 227 |
|
- incorporate modifications from Katherine Quinn to enable the use of sbo |
| 228 |
|
pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like |
| 229 |
|
output for future testreport verification (unfinished). |
| 230 |
|
o pkg/atm_phys: |
| 231 |
|
- change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R: |
| 232 |
|
skip the reseting of t_ref & q_ref to initial t & q ; this preserve the |
| 233 |
|
output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics. |
| 234 |
|
o pkg/seaice |
| 235 |
|
seaice_calc_ice_strength.F: modify expression to avoid divisions |
| 236 |
|
(affects truncation) |
| 237 |
|
seaice_do_ridging.F: clean up the insectarium |
| 238 |
|
- fix a bug that was compensated by areaScaling (-> remove areaScaling code) |
| 239 |
|
- added SEAICEsnowFracRidge to redistributed snow (2nd bug) |
| 240 |
|
- set closing/openingRate to zero where no extra iteration is need (3rd bug) |
| 241 |
|
- add some debugging information and error messages (warnings) |
| 242 |
|
o model/src: modifications relatd to atmosphere p*: |
| 243 |
|
- Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F) |
| 244 |
|
- With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead |
| 245 |
|
of vertical profile tRef in geopotential background and anomaly. |
| 246 |
|
- Acount for true p* correction in theta <-> T conversion in pkg/aim_v23 |
| 247 |
|
and pkg/atm_phys. |
| 248 |
|
- Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40, |
| 249 |
|
fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn. |
| 250 |
|
o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt |
| 251 |
|
o pkg/ptracers: compute ptracer source/sink due to linear free surface. |
| 252 |
|
not used right now, but can be used in BGC packages to fix conservation. |
| 253 |
|
o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by |
| 254 |
|
other packages too. |
| 255 |
|
o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by |
| 256 |
|
SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix) |
| 257 |
|
o model/src: |
| 258 |
|
- since we have several heat capacity (even in model/src), define "recip_Cp" |
| 259 |
|
as local variable (no longer in common block) to avoid any confusion. |
| 260 |
|
- add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords). |
| 261 |
|
o pkg/exf: |
| 262 |
|
- from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local |
| 263 |
|
air density as function of air Temp, Humidity and atm pressure. |
| 264 |
|
|
| 265 |
|
checkpoint64w (2014/05/02) |
| 266 |
|
o verification: |
| 267 |
|
- update output_adm.txt files for experiment global_ocean.cs32x15 (seaice & |
| 268 |
|
seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing |
| 269 |
|
code from seaice_growth.F & seaice_advdiff.F to new ridging routines |
| 270 |
|
seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient |
| 271 |
|
(down to 8-7 matching digits for global_ocean and 5-6 for lab_sea). |
| 272 |
|
o model/src: for atmosphere in p* coords: |
| 273 |
|
- store factor rStarFacC**atm_kappa (= pStarFacK) in common block |
| 274 |
|
- implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F), |
| 275 |
|
but not yet activated. |
| 276 |
|
o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation: |
| 277 |
|
- move computation of opnWtrFrac = 1-AREA to before computing ice strength |
| 278 |
|
- this changes the results (but not for any verification experiment, because |
| 279 |
|
none tests this), but avoids having an extra field in the restart files |
| 280 |
|
o pkg/seaice: remove global variable TICE (not needed) |
| 281 |
|
- replace by TICES or local variable where necessary (cost_seaice_test, |
| 282 |
|
seaice_diagnostics_state) |
