5      ==============================      ==============================
6    
7    o verification/advect_xz
8      - scale down the depth by 1/100 (from 200 km to just 2.km)
9      - add secondary test using divergent flow, r-star and implicit vertical advection.
10    o pkg/rbcs:
11      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
12    o pkg/obcs (Stevens BCs):
13      - fix various problems in the phase speed computations of the Stevens
14        boundary conditions:
15        - sign error for western and southern boundaries,
16        - time tendencies were underestimated by factor of dTracerLev and some just
17          zero (for multidim advection schemes) -> now estimate time tendencies
18          from difference between previous (n) time level and the one before (n-1);
19          this requires storing a field per tracer per boundary, also in the pickup
20          files.
21        - replace deltaTmom in cflMer/Zon computation with dTracerLev
22        - set default phase velocity to cflMer/Zon
23      - update verification experiment exp4.stevens
24    o pkg/generic_advdiff (implicit_r):
25      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
26        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
27      - fix implicit vertical diffusion or advection with NonLin FreeSurf
28        (was using current recip_hFacC instead of future recip_hFacC): set future
29        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
30        solver S/R ;
31      - fill diagnostics of vertical advective fluxes (computed from tendency)
32        when using implicit vert. advection;
33      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
34         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
35         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
36         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
37    o pkg/diagnostics:
38      - add diags for T & S tendency which goes through Adams-Bashforth.
39    
40    checkpoint63f (2011/11/30)
41    o pkg/obcs/obcs_calc_stevens.F:
42      - join some loops to reduce number of if-statements
43      - fix a bug in code for northern and southern boundaries.
44    o pkg/seaice/seaice_init_varia.F
45      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
46        caused zero ice-velocities for the B-grid code
47    o pkg/seaice/seaice_init_fixed.F
48      - fix a bug in the initialisation of the second metric terms
49        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
50      - this affects all seaice configurations with useCurviLinearGrid = .true.
51        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
52        = .true. (default)
53      - the only verification experiment affected is global_ocean.cs32x15:
54        icedyn, seaice, and seaice_dynmix (AD)
55    o pkg/thsice/thsice_diagnostics_state.F
56      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
57        not contain garbage that can lead to surprises in diagstats_calc.F
58    o model/src:
59      - move bi,bj loops inside INTEGR_CONTINUITY ;
60      - call INTEGR_CONTINUITY directly from forward_step.F
61        (previously called from momentum_correction_step.F)
62      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
63        forward_step.F and pkg/ecco/the_main_loop.F
64    o model/src/do_oceanic_phys.F:
65      - reset addMass to zero only if useICEFRONT ;
66      - separated k-loop for rhoInSitu calculation ;
67      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
68        and at constant T,S (= WdRHOdP);
69      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
70        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
71        transport of locally-referenced potential density);
72        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
73    o gluemnc:
74      - replace ncrcat with ncks when adding variables to *.glob.nc
75      - change the way variables without record dimensions are handled so that
76        files that have variables with and without record variables can be glued:
77        add a record dimension with a new unique name to be able to differentiate
78        between variable with and without a-prior record dimensions. Remove
79        this record dimension before adding the variable to the *.glob.nc file.
80        This procedure automatically works also for grid.*.nc files that do not
81        have any record dimension.
82    o verification/cpl_aim+ocn:
83      - generate new reference output on baudelaire (gfortran, mpich2) (previously
84        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
85    o pkg/obcs/obcs_calc_stevens.F:
86      - add code for northern and southern boundaries.
87      - reorder some loops to save some operations and so that drFBar can be scalar
88    o model/src:
89      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
90        truncation) and add diagnostics for Adams-Bashforth tendency increment.
91      - update test-exp. AD output:
92        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
93      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
94        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
95        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
96        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
97        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
98        tutorial_plume_on_slope.
99    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
100      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
101      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
102      does not even come with an F77 compiler anymore, this should not be
103      a limitation
104    
105    checkpoint63e (2011/11/06)
106    o pkg/seaice adjoint of LSR:
107      - substantially rework STORE dirs.
108      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
109        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
110        and only perform SOLV_MAX_FIXED adjoint iters.
111        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
112        always goes to same record, meaning that the last forward field will be
113        the one used in the adjoint - an approximation.
114      - now produces non-zero LSR-related gradients, and acceptable gradients for
115        An's zonal (x-z) test case (to be checked in)
116      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
117        (but these are screwed up by the thermodynamics in the first place);
118        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
119        output_adm.txt also reflects changes to seaice_lsr
120      - global_ocean.cs32x15:
121        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
122          (output_adm.seaice.txt was updated)
123        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
124          (output_adm.seaice_dynmix.txt)
125    o test-exp. exp4+stevens:
126      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
127    o pkg/seaice (lsr solver):
128      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
129        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
130      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
131      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
132        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
133      - compute (with new S/R) and print initial (+ free-driff sol. if available)
134        and final residual of linearised system.
135    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
136      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
137    o pkg/obcs: Stevens BCs (still only for east and west)
138      - fix Stevens BCs by using intermediate velocities of previous
139        time step as "baroclinic" contribution rather velocity of one grid cell
140        inside the boundaries; more consistent but makes the entire treatment
141        more complicated, requires new pickup files and two new S/Rs:
142        obcs_copy_uv_n and obcs_save_uv_n
143        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
144        (undefined by default)
145      - silently move computation of some grid factors into separate loops to
146        save some recomputations
147      - add a hack for non-linear free surface
148      - add a verification experiment to exp4 that tests this code
149    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
150    
151    checkpoint63d (2011/10/25)
152    o pkg/obcs + seaice-dynamics:
153      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
154        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
155        values (consistent with an implicit method).
156      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
157        return to older implementation (same results as before); note that none of
158        the "experimental" OBCS_SEAICE options are implemented in the new version.
159      - switch test exp. seaice_obcs to use new version (update output).
160    o pkg/seaice:
161      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
162      - add parenthesis in Water-Ice drag calculations (evp & lsr);
163      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
164        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
165      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
166        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
167    o pkg/layers:
168      - Include potential density as new coordinate (Thanks to David Munday)
169    o pkg/dic:
170      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
171        carbonate computation/output to CALC_PCO2_APPROX
172    o pkg/generic_advdiff
173      - make TAF generate code that vectorizes:
174        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
175    o model/src:
176      - improve vectorization also for adjoint code of
177        solve_tridiagonal and solve_pentadiagonal. As this requires up to
178        5 new 3D-fields, this code is only turned on for the combination of
179        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
180        for singular matrix check (only for TARGET_NEC_SX).
181      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
182        ALLOW_AUTODIFF. This flag now needs to be set outside of
183        solve_tri/pentadiagonal.F
184    o pkg/exf:
185      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
186        optional namelist EXF_NML_OBCS).
187      - add many debug-print (to trace down where pkg/cal error msg comes from)
188    o pkg/mom_vecinv/mom_vi_hdissip.F
189      - rearrange loops so that vectorization is improved and in particular
190        the adjoint routine vectorizes. The code is a little longer now, but I
191        think easier to read.
192        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
193    o pkg/seaice:
194      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
195    o pkg/exch2:
196      - alternative code (without tile x tile matrix) for cumulated (global) sum;
197        used as default; keep using matrix version in adjustment.cs-32x32x1.
198    o tools/build_options:
199      - after merging some MPI and/or multi-threads specific optfiles so that
200        the modified default optfile support both built (using genmake2 -mpi
201        for the MPI built, using genmake2 -omp for OpenMP built),
202        move now obsolete optfiles to tools/build_options/unsupported/
203       (add copy of email sent to support list in doc/optfiles_changes.txt)
204    
205    checkpoint63c (2011/09/28)
206    o pkg/ebm:
207      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
208        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
209    o pkg/seaice (SItracer pickup)
210    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
211      To be done:
212      - thorough testing of missing fields in S/R seaice_read_pickup
213      - thorough matching between generic tracers and specific fields used
214        (e.g. volume-weighted age, area-weighted age, salinity, ...)
215    o pkg/grdchk:
216      - all procs calculate and print finite-difference gradient (for testreport)
217      - change description output used by testreport;
218      - AD testing: also compare and report Finite-difference gradient;
219        => update all output_adm*.txt
220    o test exp. global_ocean_ebm:
221      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
222        and turn on exactConserve; update (fwd) output.
223    o pkg/seaice (LSR):
224      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
225      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
226        * identical results with non-CS topology (but save up to half of EXCH calls)
227        * no much changes in cs-32 verification tests since no ice at face edges
228         (differences due to convergence criteria, since nb of iterations changed)
229        * expect some differences on lat-lon-cap grid.
230        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
231    o pkg/exch2:
232      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
233        many tiles); until alternative coding is added, just add a stop.
234    o pkg/kpp:
235      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
236        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
237    o optfiles:
238      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
239        into corresponding standard one, which now support different build:
240        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
241      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
242    o pkg/obcs (seaice):
243      - add missing EXCH for uIce,vIce after applying OBCS;
244      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
245        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
246        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
247      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
248      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
249        and eedata.mth for MPI and mutlti-threaded testing.
250    o pkg/flt:
251      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
252      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
253      - fix pickup and trajectories + profiles output with multi-threads;
254      - add parameter to select group of fields to write along trajectory and
255        profile (default unchanged);
256      - only call PORT_RAND* function when flt_noise <> 0;
257      - add multi-threaded test for verification exp. flt_example.
258    o eesupp/src:
259      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
260      - USE_OMP_THREADING: check that number of threads (from eedata) matches
261        actual number (from env.var. setting).
262  o pkg/ebm:  o pkg/ebm:
263    - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.    - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
264    - add multi-threaded test for verification exp. global_ocean_ebm    - add multi-threaded test for verification exp. global_ocean_ebm
