|
o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code: |
| 8 |
|
- new subroutines seaice_lsr_tridiagu/v |
| 9 |
|
- introduce loop bounds i/jmin/max to be able to use a restricted |
| 10 |
|
additive Schwarz method, but not used for now. |
| 11 |
|
- rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS |
| 12 |
|
- use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner |
| 13 |
|
o OpenAD support |
| 14 |
|
Reorganize S/R call for overall time-stepping loop to facilitate |
| 15 |
|
OpenAD revolve loop replacement |
| 16 |
|
(new S/R main_do_loop.F) |
| 17 |
|
o model/src: |
| 18 |
|
- add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3; |
| 19 |
|
- pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R |
| 20 |
|
ADAMS_BASHFORTH2. |
| 21 |
|
o pkg/cheapaml: |
| 22 |
|
- add new parameter (default=F, same as before) to disable full domain |
| 23 |
|
(including land) periodicity in X & Y dir. |
| 24 |
|
- new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of |
| 25 |
|
prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer |
| 26 |
|
into single S/R CHEAPAML_TIMESTEP. |
| 27 |
|
|
| 28 |
|
checkpoint64d (2013/02/17) |
| 29 |
|
o pkg/monitor (angular momentum): |
| 30 |
|
- do not add Eta contribution to the total AM if using rigid-lid; |
| 31 |
|
- correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta). |
| 32 |
|
- horizontal discretisation: compute Zonal wind contribution separately for |
| 33 |
|
each component (instead of from cell centered averaged) and use the 4 |
| 34 |
|
grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part. |
| 35 |
|
- Check that AM is conserved with linear dynamics (momAdvection=F and linear |
| 36 |
|
FreeSurf) if using vectorInvariant momentum. |
| 37 |
|
o model/src (horizontal grid): |
| 38 |
|
- move initialisation of all horizontal grid arrays to null value |
| 39 |
|
from specific horizontal grid S/R to main S/R INI_GRID; |
| 40 |
|
- add 2 new arrays to project model C-grid velocity on to zonal direction |
| 41 |
|
(similar to AngleCosC & -AngleSinC but at U and V point location) and |
| 42 |
|
compute them in S/R CALC_GRID_ANGLES. |
| 43 |
|
o pkg/seaice: replace a hard coded parameter by a runtime parameter |
| 44 |
|
SEAICE_JFNK_tolIter |
| 45 |
|
o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in |
| 46 |
|
preconditioner for JFNK (run LSR into the overlaps as far as possible, |
| 47 |
|
i.e OLx/y-2, but overwrite the solution in the overlaps) |
| 48 |
|
- extend loop range in seaice_calc_viscosity |
| 49 |
|
- add new parameters SEAICE_OLx/y (default = OLx/y-2) |
| 50 |
|
- add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs |
| 51 |
|
- slightly modify loops in tridiagonal solver lsr-preconditioner |
| 52 |
|
- by default remove the extra exchange in seaice_preconditioner with a |
| 53 |
|
replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE |
| 54 |
|
- modify offline_exf_seaice so that old results without RAS are reproduced |
| 55 |
|
for output.dyn_jfnk.txt |
| 56 |
|
in seaice_fgmres.F (unrelated to RAS) |
| 57 |
|
- add a cpp-flag option for a re-ordered mapping (potentially more |
| 58 |
|
efficient), but because this changes the results, turn it off by |
| 59 |
|
default |
| 60 |
|
- replace the save statement by local common blocks |
| 61 |
|
o utils/matlab: |
| 62 |
|
- fix tile-offset in rdmnc.m when output was produced using EXCH2. |
| 63 |
|
- update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab) |
| 64 |
|
instead of local script "load_cs.m". |
| 65 |
|
o pkg/seaice: |
| 66 |
|
- fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected |
| 67 |
|
to the scalarProductMetric and the unrolling. By chance this does not |
| 68 |
|
change the verification experiment, because of the particular domain |
| 69 |
|
decomposition |
| 70 |
|
o pkg/diagnostics: |
| 71 |
|
- change default missing_value from UNSET_RL to -999. |
| 72 |
|
o pkg/layers: improve vectorization of layers_fluxcalc.F |
| 73 |
|
- step 1: split loops, make TatU/V 2D arrays. This alone reduces the cpu |
| 74 |
|
time spent in this routine by more than a factor of 3 on an NEC-SX8 |
| 75 |
|
- step 2: replace search algorithm by a bisection algorithm found in |
| 76 |
|
Press et al. Numerical Recipes in Fortran. This algorithm can be |
| 77 |
|
vectorized and finds the correct bin in approx. log2(Nlayers) steps. |
| 78 |
|
For now, use this algorithm only for TARGET_NEC_SX defined. |
| 79 |
|
- moved the search algorithm into a separate subroutine, that is kept |
| 80 |
|
within the same file for automatic inlining. |
| 81 |
|
- modified catching potential errors |
| 82 |
|
o pkg/ecco: |
| 83 |
|
- add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY. |
| 84 |
|
o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk : |
| 85 |
|
- modifications for ALLOW_GENTIM2D_CONTROL |
| 86 |
|
-- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes. |
| 87 |
|
-- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid ) |
| 88 |
|
-- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc |
| 89 |
|
-- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F |
| 90 |
|
o model/src: |
| 91 |
|
- account for moist thermodynamics in (dry) potential temperature equation; |
| 92 |
|
update results of experiments: aim.5l_cs (x2), fizhi-cs (std + aqualev) |
| 93 |
|
and cpl_aim+ocn. |
| 94 |
|
- also switch to standard compiler (gfortran, was using ifort previously) |
| 95 |
|
for fizhi-cs experiments reference output. |
| 96 |
|
o pkg/ctrl: |
| 97 |
|
- 1st step toward generic time-varying control variable (2D) via CPP option |
| 98 |
|
ALLOW_GENTIM2D_CONTROL |
| 99 |
|
- note new namelist ctrl_nml_genarr in data.ctrl |
| 100 |
|
o verification/global_ocean.cs32x15: |
| 101 |
|
- switch off OLD_THSICE_CALL_SEQUENCE (both forward and AD code) to use new |
| 102 |
|
thsice calling sequence and update "output.icedyn.txt" output file. |
| 103 |
|
o pkg/ptracers: |
| 104 |
|
- from Ryan A.: code to allow to restart a tracer at regular time interval |
| 105 |
|
specifying a reset frequency and a reset-phase (for each tracers). |
| 106 |
|
o pkg/thsice: |
| 107 |
|
- implement new sequence of calls for thsice+seaice: |
| 108 |
|
previously: ice-Dyn,ice-Advect,ice-Thermo(thsice) |
| 109 |
|
new sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect |
| 110 |
|
- allows (with temporary CPP option "#define OLD_THSICE_CALL_SEQUENCE" |
| 111 |
|
in CPP_OPTIONS.h) to recover old sequence; |
| 112 |
|
- update diagnostics for Intermediate State thsice diagnostics: now filled |
| 113 |
|
just before advection (instead of just after advection in old sequence); |
| 114 |
|
- update output of experiment offline_exf_seaice (standard test); |
| 115 |
|
- in global_ocean.cs32x15 exp., postpone output.icedyn.txt update |
| 116 |
|
by setting #define OLD_THSICE_CALL_SEQUENCE in CPP_OPTIONS.h |
| 117 |
|
o pkg/aim_v23: |
| 118 |
|
- use tiled array for aim_CO2 and surface wind speed for export to coupler; |
| 119 |
|
- use standard pkg/mdsio routines to read & write CO2 pickup file; |
| 120 |
|
- in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F; |
| 121 |
|
- Implement new sequence of calls for seaice advection (with thsice and |
| 122 |
|
seaice diffusion): do ice advection after ice-Thermodynamic (previously |
| 123 |
|
was done before); change aim_do_physics.F (split the bi,bj loops block); |
| 124 |
|
- use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence; |
| 125 |
|
o pkg/thsice: |
| 126 |
|
- add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case |
| 127 |
|
where just seaice diffusion is used without seaice-dynamics. |
| 128 |
|
|
| 129 |
|
checkpoint64c (2013/01/18) |
| 130 |
|
o pkg/seaice: |
| 131 |
|
- add a parameter JFNKres_tFac that can replace JFNKres_t |
| 132 |
|
(= JFNKres_tFac*JFNKresidual before JFNK solver) |
| 133 |
|
- add a line search option to the JFNK solver |
| 134 |
|
- move update of u/vIce and computation of initial residual into a separate |
| 135 |
|
routine (same file); makes the code a little easier to read (?) |
| 136 |
|
- the line search requires computation of the residual and for some reason |
| 137 |
|
I cannot do the update of u/vIce at the beginning of the Newton loop |
| 138 |
|
without changing the results, so we move computation of the new residual |
| 139 |
|
also to the end of the Newton loop, even without the line search |
| 140 |
|
o pkg/mdsio: |
| 141 |
|
- write missing value (corresponding to undefined array value) to meta files; |
| 142 |
|
skip this if missing value is one (UNSET_RL would be a better value for the |
| 143 |
|
case of undefined missing value but it's current the default missing-value); |
| 144 |
|
Also update mdsio_read_meta.F (reading timeInterval & missing-value). |
| 145 |
|
o pkg/exf & thsice: |
| 146 |
|
- for diagnostics purpose, fill-up and update Qsw array (+ fill the |
| 147 |
|
diagnostics) even when SHORTWAVE_HEATING is #undef; |
| 148 |
|
o verification/cfc_example: |
| 149 |
|
- turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to |
| 150 |
|
illustrate how to use it). |
| 151 |
|
o verification/offline_exf_seaice: |
| 152 |
|
in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing |
| 153 |
|
files to only one time-record. |
| 154 |
|
in input.thermo: narrow the 2 bands of low initial ice-concentration near |
| 155 |
|
N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for |
| 156 |
|
snapshot output; same mcPheePiston value as in thsice with |
| 157 |
|
surf-current=0.2m/s. |
| 158 |
|
in input.thsice: similar set-up as in input.thermo (channel with same seaice |
| 159 |
|
initial conditions). |
| 160 |
|
o verification/cfc_example: |
| 161 |
|
- update file "data" with more standard choice (default rotationPeriod, |
| 162 |
|
exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F, |
| 163 |
|
set deltaTFreeSurf to deltaTtracer) and update the output. |
| 164 |
|
o pkg/layers: |
| 165 |
|
- fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC; |
| 166 |
|
- ensure that "layers_bolus" is switched to False when useGMRedi=False. |
| 167 |
|
o verification/offline_exf_seaice: |
| 168 |
|
- set all {field}period to zero for constant-in-time forcing (not tested |
| 169 |
|
anywhere else). |
| 170 |
|
o verification/offline_exf_seaice: |
| 171 |
|
- dyn_lsr : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice; |
| 172 |
|
- dyn_jfnk : use pkg/thsice S/R (instead of pkg/seaice) to advect sea-ice. |
| 173 |
|
o model/src: |
| 174 |
|
- implement Finite-Volume method for (hydrostatic) presure gradient |
| 175 |
|
from S.-J. Lin (QJRMS 1997), for atmosphere using sigma-coordinate. |
| 176 |
|
o pkg/seaice: implement EVP* by Lemieux et al. (2012). |
| 177 |
|
- In order to be compatible with the default EVP code, this requires changing |
| 178 |
|
the EVP code around a little; and because any small change immediately |
| 179 |
|
breaks the lab_sea.hb87 verification experiment, the reference output is |
| 180 |
|
updated two times (each time the remaining aggrement was only 2 digits): |
| 181 |
|
- after replacing 1/dt by 1*recip_dt with a precomputed recip_dt |
| 182 |
|
- after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt |
| 183 |
|
The adjoint test lab_sea.evp also needed to be updated. |
| 184 |
|
- Turn on EVP* by setting SEAICE_deltaTevp as before, and setting |
| 185 |
|
SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be |
| 186 |
|
a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps |
| 187 |
|
explicitly with SEAICEnEVPstarSteps (thereby overriding the default of |
| 188 |
|
INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately |
| 189 |
|
kept obscure, because I need to test it a little more. |
| 190 |
|
o pkg/cheapaml: |
| 191 |
|
- fix few incorrect type (_RL/_RS) in subroutine calls. |
| 192 |
|
o pkg/seaice: |
| 193 |
|
- new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays |
| 194 |
|
to _RL vector; this fixes JFNK code when compiling with "-use_r4" option. |
| 195 |
|
o model/src: |
| 196 |
|
- add a warning if using select_rStar=2 with nonlinFreeSurf <> 4; |
| 197 |
|
change (in input_ad*/data) select_rStar from 2 to 1 for AD verification |
| 198 |
|
experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output) |
| 199 |
|
o pkg/cheapaml: |
| 200 |
|
- replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and |
| 201 |
|
update output of experiment cheapAML_box. |
| 202 |
|
- store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity, |
| 203 |
|
and set them only in one place (cheapaml_readparms.F). |
| 204 |
|
- replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI" |
| 205 |
|
- remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms) |
| 206 |
|
and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia). |
| 207 |
|
o model/src/the_main_loop.F: |
| 208 |
|
- fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION. |
| 209 |
|
o pkg/seaice: |
| 210 |
|
- remove legacy branch code. |
| 211 |
|
- retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly. |
| 212 |
|
o verification/*/code*/SEAICE_OPTIONS.h: |
| 213 |
|
- remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY, |
| 214 |
|
SEAICE_CAP_HEFF). |
| 215 |
o pkg/cheapaml: |
o pkg/cheapaml: |
| 216 |
- use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time |
- use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time |
| 217 |
to load new forcing fields. |
