|
o verification, AD & TLM output: |
| 8 |
|
- new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple |
| 9 |
|
additions and multiplications which affect results at machine truncation |
| 10 |
|
level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5, |
| 11 |
|
lab_sea.noseaicedyn & offline_exf_seaice) and TLM output |
| 12 |
|
(1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12 |
| 13 |
|
digits of matching. |
| 14 |
|
o pkg/seaice: |
| 15 |
|
modify lsr-algorithm so that it vectorizes AND converges by using a |
| 16 |
|
"zebra" method: split vector loop into two with step size 2; this |
| 17 |
|
solves a general convergence problem for the JFNK solver on a vector |
| 18 |
|
computer. It has the potential to even improve convergence for |
| 19 |
|
non-vector machines, but it does change the results so it is turned |
| 20 |
|
off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and |
| 21 |
|
SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h |
| 22 |
|
|
| 23 |
|
checkpoint64e (2013/03/05) |
| 24 |
|
o pkg/ecco and several verification experiments: |
| 25 |
|
Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F |
| 26 |
|
from ecco package, and revert to unified routine in model/src/ |
| 27 |
|
Adjust verification experiments accordingly, especially gloal_oce_llc90 |
| 28 |
|
Should conclude long-standing work by Gael to reconsile the_main_loop with |
| 29 |
|
ECCO and will enable OpenAD's revolve loop in ECCO setup. |
| 30 |
|
o pkg/generic_advdiff: |
| 31 |
|
- implement compressible flow method for multi-dim advection (similar to |
| 32 |
|
gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since |
| 33 |
|
TAF generates many recomputations) to use it; no yet coded with implicit |
| 34 |
|
vertical advection. |
| 35 |
|
- change experiment advect_cs (new output) and advect_xy (same output) |
| 36 |
|
to test compressible flow multi-dim advection. |
| 37 |
|
o pkg/generic_advdiff: |
| 38 |
|
- fix SOM advection for unusual cases (linear Free-Surf in r*, other |
| 39 |
|
cases where linear Free-Surf is not @ k=1, e.g., useShelfIce) |
| 40 |
|
o pkg/seaice: |
| 41 |
|
- fix bug in the no-slip implementation in seaice_calc_strainrates.F, this |
| 42 |
|
bug affects two verification experiments (lab_sea and lab_sea.hb87), |
| 43 |
|
recover old (wrong) results by setting noSlipFac = 2. in |
| 44 |
|
seaice_calc_strainrates.F; |
| 45 |
|
- add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0 |
| 46 |
|
- add runtime parameter SEAICE_JFNKepsilon for that finite difference |
| 47 |
|
gradient in the Jacobian times vector operation (s/r seaice_jacvec) |
| 48 |
|
- fix line search in seaice_jfnk.F (s/r seaice_jfnk_update) |
| 49 |
|
o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code: |
| 50 |
|
- new subroutines seaice_lsr_tridiagu/v |
| 51 |
|
- introduce loop bounds i/jmin/max to be able to use a restricted |
| 52 |
|
additive Schwarz method, but not used for now. |
| 53 |
|
- rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS |
| 54 |
|
- use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner |
| 55 |
|
o OpenAD support |
| 56 |
|
Reorganize S/R call for overall time-stepping loop to facilitate |
| 57 |
|
OpenAD revolve loop replacement |
| 58 |
|
(new S/R main_do_loop.F) |
| 59 |
|
o model/src: |
| 60 |
|
- add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3; |
| 61 |
|
- pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R |
| 62 |
|
ADAMS_BASHFORTH2. |
| 63 |
|
o pkg/cheapaml: |
| 64 |
|
- add new parameter (default=F, same as before) to disable full domain |
| 65 |
|
(including land) periodicity in X & Y dir. |
| 66 |
|
- new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of |
| 67 |
|
prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer |
| 68 |
|
into single S/R CHEAPAML_TIMESTEP. |
| 69 |
|
|
| 70 |
|
checkpoint64d (2013/02/17) |
| 71 |
|
o pkg/monitor (angular momentum): |
| 72 |
|
- do not add Eta contribution to the total AM if using rigid-lid; |
| 73 |
|
- correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta). |
| 74 |
|
- horizontal discretisation: compute Zonal wind contribution separately for |
| 75 |
|
each component (instead of from cell centered averaged) and use the 4 |
| 76 |
|
grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part. |
| 77 |
|
- Check that AM is conserved with linear dynamics (momAdvection=F and linear |
| 78 |
|
FreeSurf) if using vectorInvariant momentum. |
| 79 |
|
o model/src (horizontal grid): |
| 80 |
|
- move initialisation of all horizontal grid arrays to null value |
| 81 |
|
from specific horizontal grid S/R to main S/R INI_GRID; |
| 82 |
|
- add 2 new arrays to project model C-grid velocity on to zonal direction |
| 83 |
|
(similar to AngleCosC & -AngleSinC but at U and V point location) and |
| 84 |
|
compute them in S/R CALC_GRID_ANGLES. |
| 85 |
|
o pkg/seaice: replace a hard coded parameter by a runtime parameter |
| 86 |
|
SEAICE_JFNK_tolIter |
| 87 |
|
o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in |
| 88 |
|
preconditioner for JFNK (run LSR into the overlaps as far as possible, |
| 89 |
|
i.e OLx/y-2, but overwrite the solution in the overlaps) |
| 90 |
|
- extend loop range in seaice_calc_viscosity |
| 91 |
|
- add new parameters SEAICE_OLx/y (default = OLx/y-2) |
| 92 |
|
- add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs |
| 93 |
|
- slightly modify loops in tridiagonal solver lsr-preconditioner |
| 94 |
|
- by default remove the extra exchange in seaice_preconditioner with a |
| 95 |
|
replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE |
| 96 |
|
- modify offline_exf_seaice so that old results without RAS are reproduced |
| 97 |
|
for output.dyn_jfnk.txt |
| 98 |
|
in seaice_fgmres.F (unrelated to RAS) |
| 99 |
|
- add a cpp-flag option for a re-ordered mapping (potentially more |
| 100 |
|
efficient), but because this changes the results, turn it off by |
| 101 |
|
default |
| 102 |
|
- replace the save statement by local common blocks |
| 103 |
|
o utils/matlab: |
| 104 |
|
- fix tile-offset in rdmnc.m when output was produced using EXCH2. |
| 105 |
|
- update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab) |
| 106 |
|
instead of local script "load_cs.m". |
| 107 |
|
o pkg/seaice: |
| 108 |
|
- fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected |
| 109 |
|
to the scalarProductMetric and the unrolling. By chance this does not |
| 110 |
|
change the verification experiment, because of the particular domain |
| 111 |
|
decomposition |
| 112 |
|
o pkg/diagnostics: |
| 113 |
|
- change default missing_value from UNSET_RL to -999. |
| 114 |
|
o pkg/layers: improve vectorization of layers_fluxcalc.F |
| 115 |
|
- step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu |
| 116 |
|
time spent in this routine by more than a factor of 3 on an NEC-SX8 |
| 117 |
|
- step 2: replace search algorithm by a bisection algorithm found in |
| 118 |
|
Press et al. Numerical Recipes in Fortran. This algorithm can be |
| 119 |
|
vectorized and finds the correct bin in approx. log2(Nlayers) steps. |
| 120 |
|
For now, use this algorithm only for TARGET_NEC_SX defined. |
| 121 |
|
- moved the search algorithm into a separate subroutine, that is kept |
| 122 |
|
within the same file for automatic inlining. |
| 123 |
|
- modified catching potential errors |
| 124 |
|
o pkg/ecco: |
| 125 |
|
- add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY. |
| 126 |
|
o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk : |
| 127 |
|
- modifications for ALLOW_GENTIM2D_CONTROL |
| 128 |
|
-- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes. |
| 129 |
|
-- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid ) |
| 130 |
|
-- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc |
| 131 |
|
-- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F |
| 132 |
|
o model/src: |
| 133 |
|
- account for moist thermodynamics in (dry) potential temperature equation; |
| 134 |
|
update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev) |
| 135 |
|
and cpl_aim+ocn. |
| 136 |
|
- also switch to standard compiler (gfortran, was using ifort previously) |
| 137 |
|
for fizhi-cs experiments reference output. |
| 138 |
|
o pkg/ctrl: |
| 139 |
|
- 1st step toward generic time-varying control variable (2D) via CPP option |
| 140 |
|
ALLOW_GENTIM2D_CONTROL |
| 141 |
|
- note new namelist ctrl_nml_genarr in data.ctrl |
| 142 |
|
o verification/global_ocean.cs32x15: |
| 143 |
|
- switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new |
| 144 |
|
thsice calling sequence and update "output.icedyn.txt" output file. |
| 145 |
|
o pkg/ptracers: |
| 146 |
|
- from Ryan A.: code to allow to restart a tracer at regular time interval |
| 147 |
|
specifying a reset frequency and a reset-phase (for each tracers). |
| 148 |
|
o pkg/thsice: |
| 149 |
|
- implement new sequence of calls for thsice+seaice: |
| 150 |
|
previously: ice-Dyn,ice-Advect,ice-Thermo(thsice) |
| 151 |
|
new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect |
| 152 |
|
- allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE" |
| 153 |
|
in CPP_OPTIONS.h) to recover old sequence; |
| 154 |
|
- update diagnostics for Intermediate State thsice diagnostics: now filled |
| 155 |
|
just before advection (instead of just after advection in old sequence); |
| 156 |
|
- update output of experiment offline_exf_seaice (standard test); |
| 157 |
|
- in global_ocean.cs32x15 exp., postpone output.icedyn.txt update |
| 158 |
|
by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h |
| 159 |
|
o pkg/aim_v23: |
| 160 |
|
- use tiled array for aim_CO2 and surface wind speed for export to coupler; |
| 161 |
|
- use standard pkg/mdsio routines to read & write CO2 pickup file; |
| 162 |
|
- in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F; |
| 163 |
|
- Implement new sequence of calls for seaice advection (with thsice and |
| 164 |
|
seaice diffusion): do ice advection after ice-Thermodynamic (previously |
| 165 |
|
was done before); change aim_do_physics.F (split the bi,bj loops block); |
| 166 |
|
- use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence; |
| 167 |
|
o pkg/thsice: |
| 168 |
|
- add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case |
| 169 |
|
where just seaice diffusion is used without seaice-dynamics. |
| 170 |
|
|
| 171 |
|
checkpoint64c (2013/01/18) |
| 172 |
|
o pkg/seaice: |
| 173 |
|
- add a parameter JFNKres_tFac that can replace JFNKres_t |
| 174 |
|
(= JFNKres_tFac*JFNKresidual before JFNK solver) |
| 175 |
|
- add a line search option to the JFNK solver |
| 176 |
|
- move update of u/vIce and computation of initial residual into a separate |
| 177 |
|
routine (same file); makes the code a little easier to read (?) |
| 178 |
|
- the line search requires computation of the residual and for some reason |
| 179 |
|
I cannot do the update of u/vIce at the beginning of the Newton loop |
| 180 |
|
without changing the results, so we move computation of the new residual |
| 181 |
|
also to the end of the Newton loop, even without the line search |
| 182 |
|
o pkg/mdsio: |
| 183 |
|
- write missing value (corresponding to undefined array value) to meta files; |
| 184 |
|
skip this if missing value is one (UNSET_RL would be a better value for the |
| 185 |
|
case of undefined missing value but it's current the default missing-value); |
| 186 |
|
Also update mdsio_read_meta.F (reading timeInterval & missing-value). |
| 187 |
|
o pkg/exf & thsice: |
| 188 |
|
- for diagnostics purpose, fill-up and update Qsw array (+ fill the |
| 189 |
|
diagnostics) even when SHORTWAVE_HEATING is #undef; |
| 190 |
|
o verification/cfc_example: |
| 191 |
|
- turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to |
| 192 |
|
illustrate how to use it). |
| 193 |
|
o verification/offline_exf_seaice: |
| 194 |
|
in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing |
| 195 |
|
files to only one time-record. |
| 196 |
|
in input.thermo: narrow the 2 bands of low initial ice-concentration near |
| 197 |
|
N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for |
| 198 |
|
snapshot output; same mcPheePiston value as in thsice with |
| 199 |
|
surf-current=0.2m/s. |
| 200 |
|
in input.thsice: similar set-up as in input.thermo (channel with same seaice |
| 201 |
|
initial conditions). |
| 202 |
|
o verification/cfc_example: |
| 203 |
|
- update file "data" with more standard choice (default rotationPeriod, |
| 204 |
|
exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F, |
| 205 |
|
set deltaTFreeSurf to deltaTtracer) and update the output. |
| 206 |
|
o pkg/layers: |
| 207 |
|
- fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC; |
| 208 |
|
- ensure that "layers_bolus" is switched to False when useGMRedi=False. |
| 209 |
|
o verification/offline_exf_seaice: |
| 210 |
|
- set all {field}period to zero for constant-in-time forcing (not tested |
| 211 |
|
anywhere else). |
| 212 |
|
o verification/offline_exf_seaice: |
| 213 |
|
- dyn_lsr : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice; |
| 214 |
|
- dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice. |
| 215 |
|
o model/src: |
| 216 |
|
- implement Finite-Volume method for (hydrostatic) presure gradient |
| 217 |
|
from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate. |
| 218 |
|
o pkg/seaice: implement EVP* by Lemieux et al. (2012). |
| 219 |
|
- In order to be compatible with the default EVP code, this requires changing |
| 220 |
|
the EVP code around a little; and because any small change immediately |
| 221 |
|
breaks the lab_sea.hb87 verification experiment, the reference output is |
| 222 |
|
updated two times (each time the remaining aggrement was only 2 digits): |
| 223 |
|
- after replacing 1/dt by 1*recip_dt with a precomputed recip_dt |
| 224 |
|
- after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt |
| 225 |
|
The adjoint test lab_sea.evp also needed to be updated. |
| 226 |
|
- Turn on EVP* by setting SEAICE_deltaTevp as before, and setting |
| 227 |
|
SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be |
| 228 |
|
a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps |
| 229 |
|
explicitly with SEAICEnEVPstarSteps (thereby overriding the default of |
| 230 |
|
INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately |
| 231 |
|
kept obscure, because I need to test it a little more. |
| 232 |
|
o pkg/cheapaml: |
| 233 |
|
- fix few incorrect type (_RL/_RS) in subroutine calls. |
| 234 |
|
o pkg/seaice: |
| 235 |
|
- new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays |
| 236 |
|
to _RL vector; this fixes JFNK code when compiling with "-use_r4" option. |
| 237 |
|
o model/src: |
| 238 |
|
- add a warning if using select_rStar=2 with nonlinFreeSurf <> 4; |
| 239 |
|
change (in input_ad*/data) select_rStar from 2 to 1 for AD verification |
| 240 |
|
experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output) |
| 241 |
|
o pkg/cheapaml: |
| 242 |
|
- replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and |
| 243 |
|
update output of experiment cheapAML_box. |
| 244 |
|
- store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity, |
| 245 |
|
and set them only in one place (cheapaml_readparms.F). |
| 246 |
|
- replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI" |
| 247 |
|
- remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms) |
| 248 |
|
and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia). |
| 249 |
|
o model/src/the_main_loop.F: |
| 250 |
|
- fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION. |
| 251 |
|
o pkg/seaice: |
| 252 |
|
- remove legacy branch code. |
| 253 |
|
- retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly. |
| 254 |
|
o verification/*/code*/SEAICE_OPTIONS.h: |
| 255 |
|
- remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY, |
| 256 |
|
SEAICE_CAP_HEFF). |
| 257 |
|
o pkg/cheapaml: |
| 258 |
|
- use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time |
| 259 |
|
to load new forcing fields. |
| 260 |
|
- add missing "_d 0" where it's needed; + some editing (improve indentation). |
| 261 |
|
- remove switch to "-r8" compiler option (no longer needed) in verification |
| 262 |
|
cheapAML_box, keep same output (small trucation error differences). |
| 263 |
|
o verification/offline_exf_seaice: |
| 264 |
|
- add thermodynamics only test. |
| 265 |
|
o verification/cheapAML_box: |
| 266 |
|
- split the domain in 8 (2x4) tiles; add MPI and multi-threaded test; |
| 267 |
|
keep same output (same 14 digits for cg2d). |
| 268 |
|
- switch on "-r8" compiler option (some numerical values are missing |
| 269 |
|
the "_d 0") and update output (only 6 digits for cg2d were preserved). |
| 270 |
|
|
| 271 |
|
checkpoint64b (2012/12/24) |
| 272 |
|
o pkg/cheapaml: |
| 273 |
|
- remove un-used variables (Qnet,EmPmR) from pickup files. |
| 274 |
|
- store tendency of advected variables into cheapaml pickup file |
| 275 |
|
and fix the AB-2 restart. |
| 276 |
|
o verification/offline_exf_seaice and lab_sea adjoint: |
| 277 |
|
- switch to new code (#undef SEAICE_GROWTH_LEGACY). |
| 278 |
|
- switch to 4 time steps in offline, consistent with lab_sea. |
| 279 |
|
- match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice. |
| 280 |
|
- update results after change of experiment seaice. |
| 281 |
|
o pkg/seaice: |
| 282 |
|
- remove option SEAICE_MULTICATEGORY; has been replaced with run-time |
| 283 |
|
parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is |
| 284 |
|
still defined since SEAICE_multDim needs to be set to MULTDIM value (from |
| 285 |
|
SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default. |
| 286 |
|
o model/src: |
| 287 |
|
- add run-time parameter to select CG2D solver minimum-residual solution |
| 288 |
|
(in case of a poor convergence). |
| 289 |
|
o pkg/seaice/seaice_lsr.F |
| 290 |
|
- move calculation of matrix coefficients into new |
| 291 |
|
S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same |
| 292 |
|
file; the main purpose of this change is to be able to reuse the code |
| 293 |
|
in S/R SEAICE_PRECONDITIONER |
| 294 |
|
- modify the computation of the residual so that the mass of sea-ice |
| 295 |
|
is not used twice; this simplifies the calculations, but since |
| 296 |
|
the residual is never used except when LSR_mixIniGuess.ge.4---and this is |
| 297 |
|
not tested in testreport---this does not affect the testreport results. |
| 298 |
|
o verification/seaice_obcs: |
| 299 |
|
- disable SEAICE_GROWTH_LEGACY; reset input files to match those of |
| 300 |
|
verification/lab_sea/input.salt_plume; changes results/output.txt* |
| 301 |
|
o model/src: |
| 302 |
|
- adapt quasi-hydrostatic formulation to work with p or p* coordinate. |
| 303 |
|
o pkg/seaice: |
| 304 |
|
- improve description of parameters in seaice_fgmres.F and start |
| 305 |
|
cleaning up the code |
| 306 |
|
- change name of SCALPROD to SEAICE_SCALPROD and modify meaning of |
| 307 |
|
second argument |
| 308 |
|
- add a metric based on grid cell area to SEAICE_SCALPROD; update |
| 309 |
|
results of offline_exf_seaice.dyn_jfnk |
| 310 |
|
- compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD |
| 311 |
|
o pkg/aim_v23: |
| 312 |
|
- fix an other bug in dissipation heating (grid-cell area was missing). |
| 313 |
|
o model/src + pkg/seaice: |
| 314 |
|
- add global (multi-tile) linear solver for pair of tri-diagonal system |
| 315 |
|
along X and Y lines, respectively for U and V component. |
| 316 |
|
Note: 1) MPI and cube-exchange not yet coded. |
| 317 |
|
2) probably not accurate for poorly conditioned / large size problem. |
| 318 |
|
- add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver; |
| 319 |
|
default: not compiled and not used. |
| 320 |
|
o pkg/seaice: |
| 321 |
|
- first attempt at a multi-threaded fgmres solver for the JFNK solver: |
| 322 |
|
introduce bi/bj loops and use global_sum_tile_rl instead of |
| 323 |
|
mpi_allreduce in seaice_fgmres.F |
| 324 |
|
- improve diagnostics output for fgmres solver (seaice_fgmres.F) |
| 325 |
|
- replace a few unnecessary goto statements by if-blocks (seaice_fgmres.F) |
| 326 |
|
- add a verification experiment for JFNK in offline_exf_seaice |
| 327 |
|
o verification: |
| 328 |
|
- change (for now, only fwd test) offline_exf_seaice experiment: |
| 329 |
|
use a re-entrant channel with idealized coastline (trapezoidal shape) |
| 330 |
|
at southern boundary to explore seaice dynamics and thermodynamics |
| 331 |
|
with simple forcing. Main set-up has dynamics+thermo and SST relaxation; |
| 332 |
|
secondary test (input.thsice) use thermodynamics only with SST relaxation. |
| 333 |
|
- add seaice-dynamics only secondary test using LSR and pkg/thsice advection. |
| 334 |
|
o pkg/exf: |
| 335 |
|
- disable "sstExtrapol" when Nr=1 |
| 336 |
|
o verification: |
| 337 |
|
- add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble) |
| 338 |
|
to test pkg/cheapaml. |
| 339 |
|
o pkg/aim_v23 & pkg/shap_filt: |
| 340 |
|
- fix dissipation heating (erroneous gravity multiplication factor). |
| 341 |
|
o pkg/seaice: |
| 342 |
|
- remove unused field pressPre from jfnk solver |
| 343 |
|
- rename two subroutines in seaice_preconditioner.F |
| 344 |
|
o eesupp/src: |
| 345 |
|
- S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...) |
| 346 |
|
o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again |
| 347 |
|
- remove wrong parts of the rhs and the lhs (were in there |
| 348 |
|
because I did not understand the concept of this preconditioner) |
| 349 |
|
- add an exchange between u- and v-sweep. This increases communication |
| 350 |
|
by a factor of two but improves the convergence of jfnk. Ideally, |
| 351 |
|
one would like the u- and v-sweep to be independent. So far within |
| 352 |
|
undocumented ifdefs |
| 353 |
|
- reorganize the extra computations for printing the residuals |
| 354 |
|
o tools/genmake2: |
| 355 |
|
- comment out the "mpif.h" include in NetCDF test programm (for MPI built) |
| 356 |
|
since it's not necessary (and was preventing to use MNC in some cases). |
| 357 |
|
|
| 358 |
|
checkpoint64a (2012/11/16) |
| 359 |
|
o pkg/autodiff: |
| 360 |
|
- improve pkg-internal logical parameter switch (inAd/inFwd mode) so that |
| 361 |
|
autodiff_readparms.F no longer depends on calling order (within |
| 362 |
|
packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h): |
| 363 |
|
rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd |
| 364 |
|
and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd. |
| 365 |
|
o pkg/obcs: |
| 366 |
|
- adding tidal velocity forcing capability to obcs |
| 367 |
|
for usage example, see verification/seaice_obcs/input.tides |
| 368 |
|
o pkg/seaice: |
| 369 |
|
- turn the LSR-relaxation parameters WFAU/V into runtime parameters |
| 370 |
|
SEAICE_LSRrelaxU/V |
| 371 |
|
- introduce runtime parameter SEAICEetaZmethod (=0 by default) |
| 372 |
|
o pkg/aim_v23: |
| 373 |
|
- implement heating from friction (bottom friction and stratospheric drag). |
| 374 |
|
o pkg/shap_filt: |
| 375 |
|
- fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from |
| 376 |
|
dissipation but only for Shap_funct=2, active when addFrictionHeating=T. |
| 377 |
|
o model/src: |
| 378 |
|
- move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in |
| 379 |
|
time-constant addMass field from file (addMassFile); |
| 380 |
|
- support for heating due to friction (and Kinetic Energy dissipation): |
| 381 |
|
add option, run-time switch and 3-D field array + support code ; each pkg |
| 382 |
|
or S/R can add heating contribution (if there is a sink of KE); the sum is |
| 383 |
|
accounted for as a Temperature tendency term (EXTERNAL_FORCING_T). |
| 384 |
|
o pkg/seaice: |
| 385 |
|
- complete merge of ITD code into seaice_growth.F |
| 386 |
|
from MITgcm_contrib/torge/itd/code/ |
| 387 |
|
no verification so far, but Torge Martin tested |
| 388 |
|
"1-D test case and Beaufort set up; |
| 389 |
|
deliver okay results after 1 model year." |
| 390 |
|
- complete merge of SEAICE_SIZE.h into all relevant routines |
| 391 |
|
- move computation of eta at Z-points into calc_viscosities |
| 392 |
|
+ introduce global field etaZ |
| 393 |
|
+ add different methods for computing etaZ, for now the old |
| 394 |
|
method (simple averages of eta to Z-points) is hardwired |
| 395 |
|
+ replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual, |
| 396 |
|
seaice_preconditioner |
| 397 |
|
- simplify computations for SEAICE_ZETA_SMOOTHREG |
| 398 |
|
- seaice_preconditioner: |
| 399 |
|
+ replace one remaining press by pressLoc (mistake) |
| 400 |
|
+ adjust printing of residuals |
| 401 |
|
- improve I/O of diagnostics of JFNK in seaice_jfnk.F: |
| 402 |
|
+ add (SEAICE.h) and rename some counters (initiliased in |
| 403 |
|
seaice_init_fixed.F) |
| 404 |
|
+ add _BEGIN/END_MASTER (myThid) around print statements |
| 405 |
|
+ print total number of iterations and failures over SEAICE_monFreq |
| 406 |
|
interval to STDOUT |
| 407 |
|
- move control over output-messages by fgmres to seaice_jfnk to save |
| 408 |
|
some operations |
| 409 |
|
- move resetting initial guess for fgmres outside of seaice_fgmres_driver |
| 410 |
|
in order to make restarts with sol .ne. zero (fgmres with restarts) |
| 411 |
|
(seaice_jfnk.F, seaice_fgmres.F) |
| 412 |
|
- seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes |
| 413 |
|
a serious convergence problem when open boundaries are involved |
| 414 |
|
o pkg/ggl90: fix computation of control volumes for the case of |
| 415 |
|
ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes |
| 416 |
|
up half a grid cell from C-centered to W-centered (pointed out by C. Eden) |
| 417 |
|
o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC |
| 418 |
|
o pkg/autodiff |
| 419 |
|
- Add inAdMode switch for SEAICEuseDYNAMICS: |
| 420 |
|
SEAICEuseDYNAMICSinAdMode |
| 421 |
|
(extend logic in ADAUTODIFF_INADMODE_SET) |
| 422 |
|
o pkg/seaice |
| 423 |
|
- Step 1 of merging ice-thickness distribution (ITD) code from |
| 424 |
|
MITgcm_contrib/torge/itd/ (author: Torge Martin) |
| 425 |
|
The code implements concept laid out in Thorndike et al. (1975); |
| 426 |
|
code is enabled via CPP flag SEAICE_ITD |
| 427 |
|
nITD (in SEAICE_SIZE.h) defines number of ice thickness categories; |
| 428 |
|
code is not complete yet!! |
| 429 |
|
- SEAICE_SIZE.h now included in almost all seaice routines |
| 430 |
|
o verification (using seaice): |
| 431 |
|
- switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp. |
| 432 |
|
global_ocean.cs32x15.seaice ; update results. |
| 433 |
|
- compile B-grid dynamics in FW test exp 1D_ocean_ice_column ; |
| 434 |
|
- compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp |
| 435 |
|
offline_exf_seaice (previously compiling B-grid). |
| 436 |
|
o pkg/exf: |
| 437 |
|
- fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow |
| 438 |
|
to specify neither just 1 comp of wind or wind-stress, nor no surface momentum |
| 439 |
|
forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind. |
| 440 |
|
o pkg/layers (adjust changes from Sept 19): |
| 441 |
|
- do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F) |
| 442 |
|
this allows to remove "layers_maxNum" dimension from all layers arrays. |
| 443 |
|
o pkg/layers (adjust changes from Sept 19): |
| 444 |
|
- remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ; |
| 445 |
|
- snap-shot extended to all type of layers (not just the 1rst type); |
| 446 |
|
- remove layers variables when corresponding CPP option is undef. |
| 447 |
|
o pkg/layers: |
| 448 |
|
- rename pkg/layers variable and add new output (layer exist & un-weighted |
| 449 |
|
velocity in layer) |
| 450 |
|
o pkg/seaice: |
| 451 |
|
- simplify (?) ocean-drag coefficent computations by using |
| 452 |
|
the same routine in all three solvers (saves some code lines) |
| 453 |
|
- remove global fields DRAGA and DRAGS from C-grid code and |
| 454 |
|
declare them locally in lsr.F (the only place where they are |
| 455 |
|
still used) |
| 456 |
|
- update AD output of lab_sea.evp (very sensitive anyway). |
| 457 |
|
o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics |
| 458 |
|
(Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK |
| 459 |
|
and SEAICEuseJFNK=.true. A few things to note: |
| 460 |
|
- involves a FGMRES, that is parallel but very inefficient, |
| 461 |
|
because of many scalar products (global sums) in the Gram-Schmidt |
| 462 |
|
orthogonalization method. Needs to be replaced. Original code |
| 463 |
|
from J.-F. Lemieux |
| 464 |
|
- preconditioner for FGMRES is a stripped down version of LSOR |
| 465 |
|
- SOLV_MAX_ITERS is now used for LSOR as a solver and as a |
| 466 |
|
preconditioner. For the preconditioner, the default is set to 10. |
| 467 |
|
- Jacobian times vector is computed with finite differences |
| 468 |
|
- marginally related to JFNK-solver: add a smooth regularization for |
| 469 |
|
zeta with tanh that will improve convergence (Lemieux and Tremblay, |
| 470 |
|
2009) for any implicit solver (not implemented for EVP because EVP |
| 471 |
|
does not need this regularization in the first place). Define |
| 472 |
|
SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use. |
| 473 |
|
o eesupp/src: |
| 474 |
|
- check in genmake2 that intrinsic S/R flush is available. |
| 475 |
|
- add S/R to flush IO unit (if intrinsic S/R flush is available) |
| 476 |
|
- flush standard & error msg unit before MPI termination |
| 477 |
|
- if debugMode, flush IO unit after printing msg |
| 478 |
|
o pkg/ctrl: |
| 479 |
|
- ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call |
| 480 |
|
to ctrl_set_unpack_xyz. |
| 481 |
|
|
| 482 |
|
checkpoint64 (2012/10/09) |
| 483 |
|
o pkg/shelfice |
| 484 |
|
- in mom_fluxform.F, mom_vecinv.F: |
| 485 |
|
CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid) |
| 486 |
|
Bug fix KappaRU -> KappaRV |
| 487 |
|
does not change verification/isomip but may change other setups |
| 488 |
|
(presumably constant KappaRU=KappaRV) |
| 489 |
|
- fix diagnostics SHIU/Vdrag (thanks to Tom Millgate) |
| 490 |
|
o pkg/obcs: |
| 491 |
|
- fixed some indexing bugs in obcs_seaice_sponge.F |
| 492 |
|
- added obcs relaxation subroutines for HSALT and HSNOW |
| 493 |
|
- changes verification/seaice_obcs/results/obcs_seaice_sponge.F |
| 494 |
o pkg/seaice: |
o pkg/seaice: |
| 495 |
- add "multicategory" parameterization for snow in analogy to ice, |
- add "multicategory" parameterization for snow in analogy to ice, |
| 496 |
default is off for now. |
