|
o pkg/gmredi: |
| 8 |
|
- New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added. |
| 9 |
|
- It uses mixing length theory and suppression by steering level effects to |
| 10 |
|
calculate a diffusivity used in the Redi tensor (see Bates et al., submitted |
| 11 |
|
to JPO, for more details). |
| 12 |
|
- It also uses the diffusivity to calculate an eddy induced streamfunction |
| 13 |
|
based on a PV closure (rather than a buoyancy closure as in GM). |
| 14 |
|
- New files added to pkg/gmredi: |
| 15 |
|
gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy |
| 16 |
|
induced overturning streamfunction (called from gmredi_calc_tensor) |
| 17 |
|
gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required |
| 18 |
|
for use in gmredi_k3d |
| 19 |
|
gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate |
| 20 |
|
the eddy diffusivity |
| 21 |
|
|
| 22 |
|
checkpoint64i (2013/06/18) |
| 23 |
|
o pkg/cheapaml: |
| 24 |
|
- take src files from MITgcm_contrib/verification_other/offline_cheapaml/code |
| 25 |
|
that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics) |
| 26 |
|
with pkg/cheapaml. |
| 27 |
|
o utils/python: add subpackage for cubed sphere function, first example is |
| 28 |
|
simple cs.pcol to plot 2D fields on a map |
| 29 |
|
o pkg/streamice: |
| 30 |
|
- This is a new package in MITgcm, which solves dynamic equations for ice |
| 31 |
|
sheets and ice streams |
| 32 |
|
- At the moment it is independent of atmosphere/ocean dynamics, or any |
| 33 |
|
other physical packages in MITgcm, even ShelfIce (although it is anticipat- |
| 34 |
|
ed that this will change) |
| 35 |
|
- There is a new verification exercise that tests it, halfpipe_streamice, |
| 36 |
|
evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a |
| 37 |
|
rectangular embayment |
| 38 |
|
- halfpipe_streamice is forward-only for now, will have TAF test soon |
| 39 |
|
- for questions, email dgoldber@mit.edu |
| 40 |
|
o pkg/thsice: |
| 41 |
|
- fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing |
| 42 |
|
of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40); |
| 43 |
|
- remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new |
| 44 |
|
call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect ); |
| 45 |
|
- allow precip from pkg/cheapaml to make snow over seaice. |
| 46 |
|
o pkg/cfc: |
| 47 |
|
- move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC |
| 48 |
|
- remove atmos CFC 2-D arrays from common bloc (now local variables) |
| 49 |
|
- change some hard-coded constant to run time parameter for reading and |
| 50 |
|
and interpolating atmospheric CFC ; keep same default as previously. |
| 51 |
|
- more flexible reading of Atmos CFC (number of records no longer hard-coded) |
| 52 |
|
- put arguments in standard order: myTime, myIter, myThid |
| 53 |
|
- use standard S/R GET_PERIODIC_INTERVAL for time interpolation of |
| 54 |
|
atmospheric CFC ; fix for the case myIter < PTRACERS_iter0. |
| 55 |
|
- fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf |
| 56 |
|
- new routine to print summary of CFC params and check for consistency. |
| 57 |
|
o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff, |
| 58 |
|
similar to thsice_advdiff. |
| 59 |
|
Note that for the B-grid case the routine parameters uc/vc are overwritten. |
| 60 |
|
o pkg/cfc: |
| 61 |
|
- change time interpolation for atmospheric CFC-11 (now same as for CFC-12); |
| 62 |
|
update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline. |
| 63 |
|
- fix interpolation of atmphspheric CFC between Sorthern and Northern |
| 64 |
|
hemisphere value. |
| 65 |
|
o pkg/seaice: |
| 66 |
|
- allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml) |
| 67 |
|
o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics; |
| 68 |
|
so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE. |
| 69 |
|
- requires an additional time level that is stored in the pickup |
| 70 |
|
- you can start with AB2 from a pickup without this time level with |
| 71 |
|
pickupStrictlyMatch = .false. |
| 72 |
|
|
| 73 |
|
checkpoint64h (2013/05/26) |
| 74 |
|
o pkg/cheapaml: |
| 75 |
|
- replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux); |
| 76 |
|
affect machine truncation (but exp cheapAML_box still pass with 13 digits). |
| 77 |
|
- consistent treatment of uWind,vWind location: assume everywhere in |
| 78 |
|
pkg/cheapaml that they are on C-grid (@ uVel,vVel location) |
| 79 |
|
(Note: was already the case for Tair,Qair advection); |
| 80 |
|
add option (INCONSISTENT_WIND_LOCATION) to recover old results. |
| 81 |
|
- compute diabatic forcing only in the interior (excluding overlap regions) |
| 82 |
|
- fill in array "Qsw" (for short-wave heating); |
| 83 |
|
- add diagnostic for precip ; fill-in diagnostics for cheapAML state vars |
| 84 |
|
before any update (consistent with MITgcm state var diagnostics); |
| 85 |
|
- cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if |
| 86 |
|
non periodic ; + adjusted for uWind,vWind (C-grid). |
| 87 |
|
o pkg/seaice: |
| 88 |
|
- remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and |
| 89 |
|
add explicitly pkg/exf in experiments that currently use pkg/seaice. |
| 90 |
|
- allows to compile pkg/seaice without pkg/exf. |
| 91 |
|
o tools/OAD_support: |
| 92 |
|
- use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds |
| 93 |
|
of array "ourStepOf" in function rvNextAction (revolve.F90). |
| 94 |
|
o pkg/aim_compon_interf renamed to pkg/atm_compon_interf |
| 95 |
|
- change pkg name (to be used with other atmospheric physics pkg) |
| 96 |
|
but by-pass CVS when making the new pkg so that we keep the CVS history. |
| 97 |
|
o pkg/offline: |
| 98 |
|
- call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F |
| 99 |
|
(previously called from pkg/dic_surfforcing_init.F) |
| 100 |
|
o model/src: |
| 101 |
|
- re-order sequence of calls within packages_init_variables.F, using |
| 102 |
|
standard order, except for: |
| 103 |
|
DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top), |
| 104 |
|
CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom) |
| 105 |
|
o new pkg: atm_phys |
| 106 |
|
- add entry point and source code (previously in contrib |
| 107 |
|
verification_other/atm_gray/code_gray/) for new pkg "atm_phys" |
| 108 |
|
(atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008). |
| 109 |
|
- re-order sequence of calls within packages_readparms.F, |
| 110 |
|
packages_init_fixed.F and packages_write_pickup.F |
| 111 |
|
(but skip packages_init_variables.F because of TAF issues). |
| 112 |
|
- update contrib/*/atm_gray/ experiment. |
| 113 |
|
o pkg/seaice (ITD code): |
| 114 |
|
- simplify and fix the writing of pickup-files for ITD case |
| 115 |
|
o pkg/seaice (ITD code): |
| 116 |
|
- introduce floe size dependent lateral melt for ITD case; |
| 117 |
|
- cleaning (avoid division by zero, change to f77 syntax, remove tabs) |
| 118 |
|
- update seaice_itd experiment main output. |
| 119 |
|
o pkg/thsice: |
| 120 |
|
- remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and |
| 121 |
|
declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F; |
| 122 |
|
changed accordingly pkg/atm2d. |
| 123 |
|
|
| 124 |
|
checkpoint64g (2013/05/01) |
| 125 |
|
o pkg/exf ALLOW_RUNOFTEMP |
| 126 |
|
- if defined, river and glacier runoff temperature can be read-in from |
| 127 |
|
runoftempfile; runoftempfile needs to have same format as runofffile |
| 128 |
|
o pkg/thsice (& pkg/bulk_force): |
| 129 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 130 |
|
for energy content of Precip + RunOff & Evap (like with pkg/exf). |
| 131 |
|
- change computation domain to always be the interior (without overlap). |
| 132 |
|
- fix bug (wrong overlap) when using EXF and stressReduction > 0. |
| 133 |
|
o verification/tutorial_global_oce_biogeo: |
| 134 |
|
- add preliminary OpenAD setup (still has problems) |
| 135 |
|
o pkg/seaice: |
| 136 |
|
- turn some parameters for choosing the convergence criterion of |
| 137 |
|
the inexact Newton method (JFNK) into runtime parameters for convenience |
| 138 |
|
- clean up seaice_calc_viscosities.F: remove/retire two options for |
| 139 |
|
SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes |
| 140 |
|
the results of lab_sea/input because a division has been replaced by |
| 141 |
|
a multiplication with the reciprocal (sumNorm) |
| 142 |
|
- modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve |
| 143 |
|
convergence of solver (changes results, of course), and to test some |
| 144 |
|
new features |
| 145 |
|
o model/src: |
| 146 |
|
- remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call. |
| 147 |
|
- remove unused forcing field "dQdT" and associated parameter "dQdTFile". |
| 148 |
|
- move forcing adjustment (balancing surface forcing) in specific S/R |
| 149 |
|
where might also be applied exchanges (if needed) to forcing arrays. |
| 150 |
|
o pkg/shelfice: |
| 151 |
|
- allow to specify the Ice-Shelf mass per unit area (instead of |
| 152 |
|
shelficeLoadAnomaly) and do the conversion from one to the other |
| 153 |
|
- move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA |
| 154 |
|
to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and |
| 155 |
|
(b) will be loaded in time (before calling INI_PRESSURE) in case it is |
| 156 |
|
needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc |
| 157 |
|
- update isomip experiment forward output (get machine truncation error |
| 158 |
|
from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly) |
| 159 |
|
o verification/offline_exf_seaice: |
| 160 |
|
revise data.seaice in input.thermo and input_ad and update results accordingly |
| 161 |
|
HO = 0.2, SEAICE_areaLossFormula = 2, |
| 162 |
|
SEAICE_growMeltByConv = .TRUE., |
| 163 |
|
SEAICE_doOpenWaterMelt = .TRUE., |
| 164 |
|
Improve consistency with input.thsice and fix the spurious 500m ice corners |
| 165 |
|
o verification/global_ocean.cs32x15: |
| 166 |
|
- set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0., |
| 167 |
|
in icedyn (thsice+seaice-dyn) test and update output. |
| 168 |
|
o verification/offline_exf_seaice: |
| 169 |
|
- adjust list of tested variables (with testreport) and update |
| 170 |
|
standard test output with better slection of monitored fields. |
| 171 |
|
o pkg/cd_code: |
| 172 |
|
- swtich off Adams-Bashforth on the 1rst iteration. Update output of |
| 173 |
|
experiment lab_sea.hb87 |
| 174 |
|
o tools/genmake2: |
| 175 |
|
- change default makedepend from the system default to tools/xmakedepend: |
| 176 |
|
When no makedepend is specified, select tools/xmakedepend it the test pass, |
| 177 |
|
otherwise select the system default (if exist and pass the test) or |
| 178 |
|
try to build cyrus-makedepend ; stop if none of the 3 works. |
| 179 |
|
o pkg/exf & pkg/thsice: |
| 180 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 181 |
|
for energy content of Precip + RunOff & Evap. Assumes: |
| 182 |
|
1) Rain has same temp as Air. |
| 183 |
|
2) Snow has no heat capacity (consistent with seaice & thsice pkgs) |
| 184 |
|
3) Run-Off comes at the temp of surface water (with same Cp) |
| 185 |
|
4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be |
| 186 |
|
put directly into Latent Heat flux & should use water-vapor heat capacity. |
| 187 |
|
5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent |
| 188 |
|
with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL). |
| 189 |
|
o pkg/seaice: simplify the use of CPP flags in JFNK-related files |
| 190 |
|
(compile when SEAICE_ALLOW_JFNK is defined) |
| 191 |
|
o pkg/thsice: |
| 192 |
|
- fix oceanic flux diagnostics & timeave (left from new sequence of calls |
| 193 |
|
implementation): move THSICE_AVE call after the advection (called directly |
| 194 |
|
from thsice_do_advect.F). |
| 195 |
|
o verification/global_ocean.90x40x15 and OpenAD: |
| 196 |
|
New experiment for OpenAD is identical to the one in input_ad except that |
| 197 |
|
multiDimAdvection=.FALSE., |
| 198 |
|
There is still an issue with this. |
| 199 |
|
o pkg/thsice: |
| 200 |
|
- account for ice velocity (ocean relative velocity) in turbulent heat flux |
| 201 |
|
at the base of the ice; update output of global_ocean.cs32x15 (icedyn) |
| 202 |
|
and offline_exf_seaice (main test). |
| 203 |
|
|
| 204 |
|
checkpoint64f (2013/03/31) |
| 205 |
|
o verification/OpenAD: |
| 206 |
|
- new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran. |
| 207 |
|
o verification/isomip, pkg/shelfice and OpenAD: |
| 208 |
|
- add OpenAD setup to this exp and make shelfice package work with OpenAD |
| 209 |
|
o verification/tutorial_global_oce_biogeo: |
| 210 |
|
- update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h) |
| 211 |
|
o verification/offline_exf_seaice: |
| 212 |
|
- replace adjoint experiment (now similar to fwd input.thermo/ setup). |
| 213 |
|
o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD: |
| 214 |
|
- add OpenAD setup to this exp and make ptracers package work with OpenAD |
| 215 |
|
o pkg/seaice/seaice_evp.F: |
| 216 |
|
mask the asymmetric contribution of the ice-ocean stress (when |
| 217 |
|
the turningAngle is non-zero) over open water to avoid stripes |
| 218 |
|
in the EVP-solutions after many EVP-substeps. This does not change |
| 219 |
|
the verification experiment (because turningAngle=0 in that experiment), |
| 220 |
|
but will affect other EVP solutions with turningAngle.ne.0 |
| 221 |
|
o verification, AD & TLM output: |
| 222 |
|
- new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple |
| 223 |
|
additions and multiplications which affect results at machine truncation |
| 224 |
|
level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5, |
| 225 |
|
lab_sea.noseaicedyn & offline_exf_seaice) and TLM output |
| 226 |
|
(1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12 |
| 227 |
|
digits of matching. |
| 228 |
|
o pkg/seaice: |
| 229 |
|
modify lsr-algorithm so that it vectorizes AND converges by using a |
| 230 |
|
"zebra" method: split vector loop into two with step size 2; this |
| 231 |
|
solves a general convergence problem for the JFNK solver on a vector |
| 232 |
|
computer. It has the potential to even improve convergence for |
| 233 |
|
non-vector machines, but it does change the results so it is turned |
| 234 |
|
off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and |
| 235 |
|
SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h |
| 236 |
|
|
| 237 |
|
checkpoint64e (2013/03/05) |
| 238 |
|
o pkg/ecco and several verification experiments: |
| 239 |
|
Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F |
| 240 |
|
from ecco package, and revert to unified routine in model/src/ |
| 241 |
|
Adjust verification experiments accordingly, especially gloal_oce_llc90 |
| 242 |
|
Should conclude long-standing work by Gael to reconsile the_main_loop with |
| 243 |
|
ECCO and will enable OpenAD's revolve loop in ECCO setup. |
| 244 |
|
o pkg/generic_advdiff: |
| 245 |
|
- implement compressible flow method for multi-dim advection (similar to |
| 246 |
|
gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since |
| 247 |
|
TAF generates many recomputations) to use it; no yet coded with implicit |
| 248 |
|
vertical advection. |
| 249 |
|
- change experiment advect_cs (new output) and advect_xy (same output) |
| 250 |
|
to test compressible flow multi-dim advection. |
| 251 |
|
o pkg/generic_advdiff: |
| 252 |
|
- fix SOM advection for unusual cases (linear Free-Surf in r*, other |
| 253 |
|
cases where linear Free-Surf is not @ k=1, e.g., useShelfIce) |
| 254 |
|
o pkg/seaice: |
| 255 |
|
- fix bug in the no-slip implementation in seaice_calc_strainrates.F, this |
| 256 |
|
bug affects two verification experiments (lab_sea and lab_sea.hb87), |
| 257 |
|
recover old (wrong) results by setting noSlipFac = 2. in |
| 258 |
|
seaice_calc_strainrates.F; |
| 259 |
|
- add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0 |
| 260 |
|
- add runtime parameter SEAICE_JFNKepsilon for that finite difference |
| 261 |
|
gradient in the Jacobian times vector operation (s/r seaice_jacvec) |
| 262 |
|
- fix line search in seaice_jfnk.F (s/r seaice_jfnk_update) |
| 263 |
|
o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code: |
| 264 |
|
- new subroutines seaice_lsr_tridiagu/v |
| 265 |
|
- introduce loop bounds i/jmin/max to be able to use a restricted |
| 266 |
|
additive Schwarz method, but not used for now. |
| 267 |
|
- rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS |
| 268 |
|
- use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner |
| 269 |
|
o OpenAD support |
| 270 |
|
Reorganize S/R call for overall time-stepping loop to facilitate |
| 271 |
|
OpenAD revolve loop replacement |
| 272 |
|
(new S/R main_do_loop.F) |
| 273 |
|
o model/src: |
| 274 |
|
- add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3; |
| 275 |
|
- pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R |
| 276 |
|
ADAMS_BASHFORTH2. |
| 277 |
|
o pkg/cheapaml: |
| 278 |
|
- add new parameter (default=F, same as before) to disable full domain |
| 279 |
|
(including land) periodicity in X & Y dir. |
| 280 |
|
- new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of |
| 281 |
|
prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer |
| 282 |
|
into single S/R CHEAPAML_TIMESTEP. |
| 283 |
|
|
| 284 |
|
checkpoint64d (2013/02/17) |
| 285 |
|
o pkg/monitor (angular momentum): |
| 286 |
|
- do not add Eta contribution to the total AM if using rigid-lid; |
| 287 |
|
- correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta). |
| 288 |
|
- horizontal discretisation: compute Zonal wind contribution separately for |
| 289 |
|
each component (instead of from cell centered averaged) and use the 4 |
| 290 |
|
grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part. |
| 291 |
|
- Check that AM is conserved with linear dynamics (momAdvection=F and linear |
| 292 |
|
FreeSurf) if using vectorInvariant momentum. |
| 293 |
|
o model/src (horizontal grid): |
| 294 |
|
- move initialisation of all horizontal grid arrays to null value |
| 295 |
|
from specific horizontal grid S/R to main S/R INI_GRID; |
| 296 |
|
- add 2 new arrays to project model C-grid velocity on to zonal direction |
| 297 |
|
(similar to AngleCosC & -AngleSinC but at U and V point location) and |
| 298 |
|
compute them in S/R CALC_GRID_ANGLES. |
| 299 |
|
o pkg/seaice: replace a hard coded parameter by a runtime parameter |
| 300 |
|
SEAICE_JFNK_tolIter |
| 301 |
|
o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in |
| 302 |
|
preconditioner for JFNK (run LSR into the overlaps as far as possible, |
| 303 |
|
i.e OLx/y-2, but overwrite the solution in the overlaps) |
| 304 |
|
- extend loop range in seaice_calc_viscosity |
| 305 |
|
- add new parameters SEAICE_OLx/y (default = OLx/y-2) |
| 306 |
|
- add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs |
| 307 |
|
- slightly modify loops in tridiagonal solver lsr-preconditioner |
| 308 |
|
- by default remove the extra exchange in seaice_preconditioner with a |
| 309 |
|
replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE |
| 310 |
|
- modify offline_exf_seaice so that old results without RAS are reproduced |
| 311 |
|
for output.dyn_jfnk.txt |
| 312 |
|
in seaice_fgmres.F (unrelated to RAS) |
| 313 |
|
- add a cpp-flag option for a re-ordered mapping (potentially more |
| 314 |
|
efficient), but because this changes the results, turn it off by |
| 315 |
|
default |
| 316 |
|
- replace the save statement by local common blocks |
| 317 |
|
o utils/matlab: |
| 318 |
|
- fix tile-offset in rdmnc.m when output was produced using EXCH2. |
| 319 |
|
- update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab) |
| 320 |
|
instead of local script "load_cs.m". |
| 321 |
|
o pkg/seaice: |
| 322 |
|
- fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected |
| 323 |
|
to the scalarProductMetric and the unrolling. By chance this does not |
| 324 |
|
change the verification experiment, because of the particular domain |
| 325 |
|
decomposition |
| 326 |
|
o pkg/diagnostics: |
| 327 |
|
- change default missing_value from UNSET_RL to -999. |
| 328 |
|
o pkg/layers: improve vectorization of layers_fluxcalc.F |
| 329 |
|
- step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu |
| 330 |
|
time spent in this routine by more than a factor of 3 on an NEC-SX8 |
| 331 |
|
- step 2: replace search algorithm by a bisection algorithm found in |
| 332 |
|
Press et al. Numerical Recipes in Fortran. This algorithm can be |
| 333 |
|
vectorized and finds the correct bin in approx. log2(Nlayers) steps. |
| 334 |
|
For now, use this algorithm only for TARGET_NEC_SX defined. |
| 335 |
|
- moved the search algorithm into a separate subroutine, that is kept |
| 336 |
|
within the same file for automatic inlining. |
| 337 |
|
- modified catching potential errors |
| 338 |
|
o pkg/ecco: |
| 339 |
|
- add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY. |
| 340 |
|
o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk : |
| 341 |
|
- modifications for ALLOW_GENTIM2D_CONTROL |
| 342 |
|
-- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes. |
| 343 |
|
-- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid ) |
| 344 |
|
-- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc |
| 345 |
|
-- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F |
| 346 |
|
o model/src: |
| 347 |
|
- account for moist thermodynamics in (dry) potential temperature equation; |
| 348 |
|
update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev) |
| 349 |
|
and cpl_aim+ocn. |
| 350 |
|
- also switch to standard compiler (gfortran, was using ifort previously) |
| 351 |
|
for fizhi-cs experiments reference output. |
| 352 |
|
o pkg/ctrl: |
| 353 |
|
- 1st step toward generic time-varying control variable (2D) via CPP option |
| 354 |
|
ALLOW_GENTIM2D_CONTROL |
| 355 |
|
- note new namelist ctrl_nml_genarr in data.ctrl |
| 356 |
|
o verification/global_ocean.cs32x15: |
| 357 |
|
- switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new |
| 358 |
|
thsice calling sequence and update "output.icedyn.txt" output file. |
| 359 |
|
o pkg/ptracers: |
| 360 |
|
- from Ryan A.: code to allow to restart a tracer at regular time interval |
| 361 |
|
specifying a reset frequency and a reset-phase (for each tracers). |
| 362 |
|
o pkg/thsice: |
| 363 |
|
- implement new sequence of calls for thsice+seaice: |
| 364 |
|
previously: ice-Dyn,ice-Advect,ice-Thermo(thsice) |
| 365 |
|
new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect |
| 366 |
|
- allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE" |
| 367 |
|
in CPP_OPTIONS.h) to recover old sequence; |
| 368 |
|
- update diagnostics for Intermediate State thsice diagnostics: now filled |
| 369 |
|
just before advection (instead of just after advection in old sequence); |
| 370 |
|
- update output of experiment offline_exf_seaice (standard test); |
| 371 |
|
- in global_ocean.cs32x15 exp., postpone output.icedyn.txt update |
| 372 |
|
by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h |
| 373 |
|
o pkg/aim_v23: |
| 374 |
|
- use tiled array for aim_CO2 and surface wind speed for export to coupler; |
| 375 |
|
- use standard pkg/mdsio routines to read & write CO2 pickup file; |
| 376 |
|
- in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F; |
| 377 |
|
- Implement new sequence of calls for seaice advection (with thsice and |
| 378 |
|
seaice diffusion): do ice advection after ice-Thermodynamic (previously |
| 379 |
|
was done before); change aim_do_physics.F (split the bi,bj loops block); |
| 380 |
|
- use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence; |
| 381 |
|
o pkg/thsice: |
| 382 |
|
- add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case |
| 383 |
|
where just seaice diffusion is used without seaice-dynamics. |
| 384 |
|
|
| 385 |
|
checkpoint64c (2013/01/18) |
| 386 |
|
o pkg/seaice: |
| 387 |
|
- add a parameter JFNKres_tFac that can replace JFNKres_t |
| 388 |
|
(= JFNKres_tFac*JFNKresidual before JFNK solver) |
| 389 |
|
- add a line search option to the JFNK solver |
| 390 |
|
- move update of u/vIce and computation of initial residual into a separate |
| 391 |
|
routine (same file); makes the code a little easier to read (?) |
| 392 |
|
- the line search requires computation of the residual and for some reason |
| 393 |
|
I cannot do the update of u/vIce at the beginning of the Newton loop |
| 394 |
|
without changing the results, so we move computation of the new residual |
| 395 |
|
also to the end of the Newton loop, even without the line search |
| 396 |
|
o pkg/mdsio: |
| 397 |
|
- write missing value (corresponding to undefined array value) to meta files; |
| 398 |
|
skip this if missing value is one (UNSET_RL would be a better value for the |
| 399 |
|
case of undefined missing value but it's current the default missing-value); |
| 400 |
|
Also update mdsio_read_meta.F (reading timeInterval & missing-value). |
| 401 |
|
o pkg/exf & thsice: |
| 402 |
|
- for diagnostics purpose, fill-up and update Qsw array (+ fill the |
| 403 |
|
diagnostics) even when SHORTWAVE_HEATING is #undef; |
| 404 |
|
o verification/cfc_example: |
| 405 |
|
- turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to |
| 406 |
|
illustrate how to use it). |
| 407 |
|
o verification/offline_exf_seaice: |
| 408 |
|
in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing |
| 409 |
|
files to only one time-record. |
| 410 |
|
in input.thermo: narrow the 2 bands of low initial ice-concentration near |
| 411 |
|
N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for |
| 412 |
|
snapshot output; same mcPheePiston value as in thsice with |
| 413 |
|
surf-current=0.2m/s. |
| 414 |
|
in input.thsice: similar set-up as in input.thermo (channel with same seaice |
| 415 |
|
initial conditions). |
| 416 |
|
o verification/cfc_example: |
| 417 |
|
- update file "data" with more standard choice (default rotationPeriod, |
| 418 |
|
exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F, |
| 419 |
|
set deltaTFreeSurf to deltaTtracer) and update the output. |
| 420 |
|
o pkg/layers: |
| 421 |
|
- fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC; |
| 422 |
|
- ensure that "layers_bolus" is switched to False when useGMRedi=False. |
| 423 |
|
o verification/offline_exf_seaice: |
| 424 |
|
- set all {field}period to zero for constant-in-time forcing (not tested |
| 425 |
|
anywhere else). |
| 426 |
|
o verification/offline_exf_seaice: |
| 427 |
|
- dyn_lsr : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice; |
| 428 |
|
- dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice. |
| 429 |
|
o model/src: |
| 430 |
|
- implement Finite-Volume method for (hydrostatic) presure gradient |
| 431 |
|
from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate. |
| 432 |
|
o pkg/seaice: implement EVP* by Lemieux et al. (2012). |
| 433 |
|
- In order to be compatible with the default EVP code, this requires changing |
| 434 |
|
the EVP code around a little; and because any small change immediately |
| 435 |
|
breaks the lab_sea.hb87 verification experiment, the reference output is |
| 436 |
|
updated two times (each time the remaining aggrement was only 2 digits): |
| 437 |
|
- after replacing 1/dt by 1*recip_dt with a precomputed recip_dt |
| 438 |
|
- after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt |
| 439 |
|
The adjoint test lab_sea.evp also needed to be updated. |
| 440 |
|
- Turn on EVP* by setting SEAICE_deltaTevp as before, and setting |
| 441 |
|
SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be |
| 442 |
|
a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps |
| 443 |
|
explicitly with SEAICEnEVPstarSteps (thereby overriding the default of |
| 444 |
|
INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately |
| 445 |
|
kept obscure, because I need to test it a little more. |
| 446 |
|
o pkg/cheapaml: |
| 447 |
|
- fix few incorrect type (_RL/_RS) in subroutine calls. |
| 448 |
|
o pkg/seaice: |
| 449 |
|
- new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays |
| 450 |
|
to _RL vector; this fixes JFNK code when compiling with "-use_r4" option. |
| 451 |
|
o model/src: |
| 452 |
|
- add a warning if using select_rStar=2 with nonlinFreeSurf <> 4; |
| 453 |
|
change (in input_ad*/data) select_rStar from 2 to 1 for AD verification |
| 454 |
|
experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output) |
| 455 |
|
o pkg/cheapaml: |
| 456 |
|
- replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and |
| 457 |
|
update output of experiment cheapAML_box. |
| 458 |
|
- store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity, |
| 459 |
|
and set them only in one place (cheapaml_readparms.F). |
| 460 |
|
- replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI" |
| 461 |
|
- remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms) |
| 462 |
|
and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia). |
| 463 |
|
o model/src/the_main_loop.F: |
| 464 |
|
- fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION. |
| 465 |
|
o pkg/seaice: |
| 466 |
|
- remove legacy branch code. |
| 467 |
|
- retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly. |
| 468 |
|
o verification/*/code*/SEAICE_OPTIONS.h: |
| 469 |
|
- remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY, |
| 470 |
|
SEAICE_CAP_HEFF). |
| 471 |
|
o pkg/cheapaml: |
| 472 |
|
- use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time |
| 473 |
|
to load new forcing fields. |
| 474 |
|
- add missing "_d 0" where it's needed; + some editing (improve indentation). |
| 475 |
|
- remove switch to "-r8" compiler option (no longer needed) in verification |
| 476 |
|
cheapAML_box, keep same output (small trucation error differences). |
| 477 |
|
o verification/offline_exf_seaice: |
| 478 |
|
- add thermodynamics only test. |
| 479 |
|
o verification/cheapAML_box: |
| 480 |
|
- split the domain in 8 (2x4) tiles; add MPI and multi-threaded test; |
| 481 |
|
keep same output (same 14 digits for cg2d). |
| 482 |
|
- switch on "-r8" compiler option (some numerical values are missing |
| 483 |
|
the "_d 0") and update output (only 6 digits for cg2d were preserved). |
| 484 |
|
|
| 485 |
|
checkpoint64b (2012/12/24) |
| 486 |
|
o pkg/cheapaml: |
| 487 |
|
- remove un-used variables (Qnet,EmPmR) from pickup files. |
| 488 |
|
- store tendency of advected variables into cheapaml pickup file |
| 489 |
|
and fix the AB-2 restart. |
| 490 |
|
o verification/offline_exf_seaice and lab_sea adjoint: |
| 491 |
|
- switch to new code (#undef SEAICE_GROWTH_LEGACY). |
| 492 |
|
- switch to 4 time steps in offline, consistent with lab_sea. |
| 493 |
|
- match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice. |
| 494 |
|
- update results after change of experiment seaice. |
| 495 |
|
o pkg/seaice: |
| 496 |
|
- remove option SEAICE_MULTICATEGORY; has been replaced with run-time |
| 497 |
|
parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is |
| 498 |
|
still defined since SEAICE_multDim needs to be set to MULTDIM value (from |
| 499 |
|
SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default. |
| 500 |
|
o model/src: |
| 501 |
|
- add run-time parameter to select CG2D solver minimum-residual solution |
| 502 |
|
(in case of a poor convergence). |
| 503 |
|
o pkg/seaice/seaice_lsr.F |
| 504 |
|
- move calculation of matrix coefficients into new |
| 505 |
|
S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same |
| 506 |
|
file; the main purpose of this change is to be able to reuse the code |
| 507 |
|
in S/R SEAICE_PRECONDITIONER |
| 508 |
|
- modify the computation of the residual so that the mass of sea-ice |
| 509 |
|
is not used twice; this simplifies the calculations, but since |
| 510 |
|
the residual is never used except when LSR_mixIniGuess.ge.4---and this is |
| 511 |
|
not tested in testreport---this does not affect the testreport results. |
| 512 |
|
o verification/seaice_obcs: |
| 513 |
|
- disable SEAICE_GROWTH_LEGACY; reset input files to match those of |
| 514 |
|
verification/lab_sea/input.salt_plume; changes results/output.txt* |
| 515 |
|
o model/src: |
| 516 |
|
- adapt quasi-hydrostatic formulation to work with p or p* coordinate. |
| 517 |
|
o pkg/seaice: |
| 518 |
|
- improve description of parameters in seaice_fgmres.F and start |
| 519 |
|
cleaning up the code |
| 520 |
|
- change name of SCALPROD to SEAICE_SCALPROD and modify meaning of |
| 521 |
|
second argument |
| 522 |
|
- add a metric based on grid cell area to SEAICE_SCALPROD; update |
| 523 |
|
results of offline_exf_seaice.dyn_jfnk |
| 524 |
|
- compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD |
| 525 |
|
o pkg/aim_v23: |
| 526 |
|
- fix an other bug in dissipation heating (grid-cell area was missing). |
| 527 |
|
o model/src + pkg/seaice: |
| 528 |
|
- add global (multi-tile) linear solver for pair of tri-diagonal system |
| 529 |
|
along X and Y lines, respectively for U and V component. |
| 530 |
|
Note: 1) MPI and cube-exchange not yet coded. |
| 531 |
|
2) probably not accurate for poorly conditioned / large size problem. |
| 532 |
|
- add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver; |
| 533 |
|
default: not compiled and not used. |
| 534 |
|
o pkg/seaice: |
| 535 |
|
- first attempt at a multi-threaded fgmres solver for the JFNK solver: |
| 536 |
|
introduce bi/bj loops and use global_sum_tile_rl instead of |
| 537 |
|
mpi_allreduce in seaice_fgmres.F |
| 538 |
|
- improve diagnostics output for fgmres solver (seaice_fgmres.F) |
| 539 |
|
- replace a few unnecessary goto statements by if-blocks (seaice_fgmres.F) |
| 540 |
|
- add a verification experiment for JFNK in offline_exf_seaice |
| 541 |
|
o verification: |
| 542 |
|
- change (for now, only fwd test) offline_exf_seaice experiment: |
| 543 |
|
use a re-entrant channel with idealized coastline (trapezoidal shape) |
| 544 |
|
at southern boundary to explore seaice dynamics and thermodynamics |
| 545 |
|
with simple forcing. Main set-up has dynamics+thermo and SST relaxation; |
| 546 |
|
secondary test (input.thsice) use thermodynamics only with SST relaxation. |
| 547 |
|
- add seaice-dynamics only secondary test using LSR and pkg/thsice advection. |
| 548 |
|
o pkg/exf: |
| 549 |
|
- disable "sstExtrapol" when Nr=1 |
| 550 |
o verification: |
o verification: |
| 551 |
- add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble) |
- add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble) |
| 552 |
to test pkg/cheapaml. |
