checkpoint50c_pre |
| 7 |
|
Merging from release1_p13: |
| 8 |
|
o bug fix for pkg/seaice dynamic solver |
| 9 |
|
o Added SEAICE_initialHEFF to pkg/seaice |
| 10 |
|
|
| 11 |
|
checkpoint50b_post |
| 12 |
|
o store u*,v* in gU,V instead of in guNm1,gvNm1 |
| 13 |
|
o in order to put the momForcing out of the Adams-Bashforth: |
| 14 |
|
move forcing & CD-scheme calls from mom_fluxform & mom_vecinv |
| 15 |
|
to timestep.F |
| 16 |
|
o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays |
| 17 |
|
o re-generate output for highly sensitive test-exp: |
| 18 |
|
global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box |
| 19 |
|
|
| 20 |
|
checkpoint50b_pre |
| 21 |
|
o restore the use of momAdvection & useCoriolis flags (mom_vecinv) |
| 22 |
|
o corrected CPP option mismatch in exf_Bulk... functions for case |
| 23 |
|
#define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP |
| 24 |
|
|
| 25 |
|
checkpoint50a_post |
| 26 |
|
o Bug fix for merging between c50 and KPP. |
| 27 |
|
ikey was passed from thermodynamics to kpp_calc via |
| 28 |
|
common block rather than being recomputed in kpp_calc, |
| 29 |
|
in contradiction with new key itdkey. |
| 30 |
|
New key ikppkey created, and tamc.h headers updated. |
| 31 |
|
|
| 32 |
|
checkpoint50 |
| 33 |
|
- 2nd step of merge with ecco-branch: |
| 34 |
|
merge changes in ecco-branch back into main trunk |
| 35 |
|
- bug fix in find_alpha |
| 36 |
|
- more storing in gmredi_calc_tensor.F, kpp_routines.F |
| 37 |
|
- avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC |
| 38 |
|
- merged some sliced AD support routines |
| 39 |
|
|
| 40 |
|
checkpoint49 |
| 41 |
|
merged from ecco-branch: |
| 42 |
|
o exf: |
| 43 |
|
- Enable initialisation of forcing fields to constant |
| 44 |
|
(runtime) values. |
| 45 |
|
- in exf_getffields.F |
| 46 |
|
Reduce i-/j-loop to interior domain, discarding overlaps. |
| 47 |
|
That also fixes wrong TAF-key computations for key_1, key_2 |
| 48 |
|
with bulf formulae. |
| 49 |
|
- exf_init.F modify #ifdef for exf_init_evap |
| 50 |
|
- exf_getffieldrec.F, ctrl_getrec.F |
| 51 |
|
The following INT-usages are not safe: |
| 52 |
|
fldsecs = int(fldsecs/fldperiod)*fldperiod |
| 53 |
|
fldcount = int(fldsecs/fldperiod) + 1 |
| 54 |
|
and were modified. |
| 55 |
|
o autodiff: checkpoint_lev... |
| 56 |
|
- updated storing for bulk formulae (some arrays were missing) |
| 57 |
|
- added state for seaice package |
| 58 |
|
- synchronized with main branch |
| 59 |
|
o DIVA: |
| 60 |
|
Modif.s in |
| 61 |
|
- the_main_loop.F |
| 62 |
|
- the_model_main.F |
| 63 |
|
and added cost_final_restore.F cost_final_store.F |
| 64 |
|
o With these changes, it is possible to fully separate |
| 65 |
|
the first forward run to compute the cost function (mdthe_main_loop) |
| 66 |
|
and adjoint runs over individual DIVA intervals (adthe_main_loop) |
| 67 |
|
into separate model executions. |
| 68 |
|
This enables better tuning of DIVA to given queue sizes. |
| 69 |
|
o Loss of cost function value in consecutive DIVA runs is |
| 70 |
|
fixed by storing to 'costfinal' file. |
| 71 |
|
o Appropriate call of ctrl_unpack/_pack,grdchk_main at |
| 72 |
|
beginning/end of adjoint integration is accounted for. |
| 73 |
|
The current changes apply to TAF-1.4.26. |
| 74 |
|
TAF has one remaining bug, requiring one manual change |
| 75 |
|
(see MITgcm manual). |
| 76 |
|
o cal: synchronized between MAIN and ecco-branch |
| 77 |
|
|
| 78 |
|
checkpoint48i_post |
| 79 |
|
o Changes to restore differentiability of code w.r.t. previous tag |
| 80 |
|
(mostly adding new routines to make list and replacing |
| 81 |
|
pressure by totPhiHyd). |
| 82 |
|
o Updated and merged grdchk package |
| 83 |
|
- has both ADM and TLM checks |
| 84 |
|
- works for single- and multi-proc. |
| 85 |
|
- output cleaned |
| 86 |
|
- worked successfully for parallel DIVA |
| 87 |
|
o genmake: |
| 88 |
|
- Adding -platform=SP4 |
| 89 |
|
- Modif. for DEC Alpha (many don't have makedepend; use mkdep instead). |
| 90 |
|
o Modif. for DIVA: |
| 91 |
|
ctrl_unpack should not be called in intermediate DIVA interval. |
| 92 |
|
(similar thing would apply for active files such as |
| 93 |
|
tbar, sbar, psbar, which should not be reinitialised; |
| 94 |
|
only relevant for ecco-branch) |
| 95 |
|
|
| 96 |
|
checkpoint48h_post |
| 97 |
|
o improve "ini_p_ground" when using finite difference form for calc_phi_hyd |
| 98 |
|
o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F |
| 99 |
|
o Added SEAICE_initialHEFF to pkg/seaice |
| 100 |
|
o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT |
| 101 |
|
|
| 102 |
|
checkpoint48g_post |
| 103 |
|
--- EOS: |
| 104 |
|
o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF |
| 105 |
|
store total Potential in totPhyHyd for diagnostics & EOS. |
| 106 |
|
o fix restart and overlap Pb when using Z-coord and EOS funct. of P |
| 107 |
|
--- Pressure/geopotential gradient: |
| 108 |
|
o use Ro_surf & R_low instead of hFac in cal_phi_hyd: |
| 109 |
|
o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind |
| 110 |
|
( changes results of global_ocean_pressure ) |
| 111 |
|
o NLFS + z-coord.: add eta*Rho' contribution. |
| 112 |
|
o accurate phiHyd when using interface-W at the middle between 2 centers |
| 113 |
|
( changes results of ideal_2D_oce ) |
| 114 |
|
o includes r* 2nd term in potential gradient. |
| 115 |
|
|
| 116 |
|
checkpoint48f_post |
| 117 |
|
Merging from release1_p12: |
| 118 |
|
o Modifications for using pkg/exf with pkg/seaice |
| 119 |
|
- improved description of the various forcing configurations |
| 120 |
|

| 123 |
|
o Added pkg/sbo for computing IERS Special Bureau for the Oceans |
| 124 |
|
(SBO) core products, including oceanic mass, center-of-mass, |
| 125 |
|
angular, and bottom pressure (see pkg/sbo/README.sbo). |
| 126 |
|
o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F |
| 127 |
|
to avoid negative values in shallow regions. |
| 128 |
|
- updated verification/natl_box/results/output.txt |
| 129 |
|
- updated verification/lab_sea/results/output.txt |
| 130 |
|
o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F |
| 131 |
|
o Added useSingleCpuIO option (see PARAMS.h). |
| 132 |
|
o Updated useSingleCpuIO option in mdsio_writefield.F to |
| 133 |
|
work with multi-field files, e.g., for single-file pickup. |
| 134 |
|
o pkg/seaice: |
| 135 |
|
- bug fix in growth.F: QNET for no shortwave case |
| 136 |
|
- added HeffFile for specifying initial sea-ice thickness |
| 137 |
|
- changed SEAICE_EXTERNAL_FLUXES wind stress implementation |
| 138 |
|
o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf, |
| 139 |
|
kpp_transport_t.F, forward_step.F, and the_main_loop.F |
| 140 |
|
o pkg/seaice: |
| 141 |
|
- adjoint-friendly modifications |
| 142 |
|
- added a SEAICE_WRITE_PICKUP at end of the_model_main.F |
| 143 |
|
|
| 144 |
|
checkpoint48e_post |
| 145 |
|
o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post) |
| 146 |
|
o dynamics: change definition of computational domain & adapt mom_fluxform |
| 147 |
|
accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2. |
| 148 |
|
o following exp works with Olx=Oly=2 (and pass through checkbounds option): |
| 149 |
|
adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1 |
| 150 |
|
exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5 |
| 151 |
|
global_ocean.90x40x15 global_with_exf global_ocean_pressure |
| 152 |
|
inverted_barometer solid-body.cs-32x32x1 |
| 153 |
|
(high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure) |
| 154 |
|
|
| 155 |
|
checkpoint48d_post |
| 156 |
|
o in preparation for r*: |
| 157 |
|
a) use pre-computed gradient of hydrostatic potential: |
| 158 |
|
changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce |
| 159 |
|
b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd: |
| 160 |
|
=> affects results of glob_oce_pressure (different truncation error) |
| 161 |
|
update output.txt of ideal_2D_oce & global_ocean_pressure |
| 162 |
|
|
| 163 |
checkpoint48d_pre |
checkpoint48d_pre |
| 164 |
o in preparation for r*: |
o in preparation for r*: |
| 165 |
new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient. |
