5      ==============================      ==============================
6    
7    checkpoint62k (2010/09/17)
8    o adjoint
9       * changed verification/global_ocean.cs32x15 ; adjoint now tests
10         Adams-Bashforth 3 + NLFS + RSTAR
11       * some more modifs required for ECCO-GODAE v4
12    o pkg/seaice
13       add SEAICE_AGE_VOL option to use volume instead of area for
14       integrating SEAICE_AGE
15    o model/src:
16       first check-in of sigma & hybrid-sigma coordinate code ; also includes
17       non-linear free-surface parts ; but pressure-gradient not yet coded.
18    o pkg/ptracers:
19       option for ptracer to convert Salt Relax into additional EmP.
20        tested in exp. global_ocean.90x40x15.dwnslp (update output)
21    
22    checkpoint62j (2010/08/25)
23    o pkg/ggl90:
24       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
25    o pkg/dic: car_flux.F, phos_flux.F
26      - reduce number of exp-calls in order to improve performance
27      - clean up a little (replace fields by their macros, etc., fix
28        typo in CPP-flag)
29    o pkg/ggl90: minor changes
30      - GGL90diffKrS was removed --> always use GGL90diffKr
31      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
32      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
33        (commented out for now)
34      - change in max/min operations to ensure that smoothing is ok
35      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
36      - always use diffKrNrT as background profile (i.e. never use diffKr field)
37    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
38    o pkg/dic:
39      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
40        vectorization
41      - small bug fix in insol for the unlikely case of a cartesian grid
42      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
43        + now vectorize, which also removes adjoint recomputations;
44        + replace integer maksp1 by _RL maskp1
45        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
46    
47    checkpoint62i (2010/07/21)
48    o pkg/flt:
49      - with OBCS: stop floats which enter the OB region
50    o model/src:
51      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
52        for implicit vertical advection.
53    o pkg/seaice:
54     - account for melting in seaice age evolution.
55     - remove double counting of seaice ridging effect on seaice age.
56    
57    checkpoint62h (2010/06/18)
58    o pkg/exch2:
59     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
60    o tools/genmake2
61      - remove "-pdefault" option: redundant with the use of "packages.conf";
62      - remove file pkg/pkg_default : set the default as a pkg group
63        ("default_pkg_list") defined in pkg/pkg_groups;
64      - fix for case pkg/pkg_depend is missing (was hanging before);
65      - add option "-pgroups" to specify a different pkg_groups than the default.
66    o verification/adjustment.cs-32x32x1:
67       add a "minimal" set-up test (code_min & input_min) which only compiles
68       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
69    o tools/genmake2
70      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
71      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
72    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
73      files are nearly the same anyway.
74      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
75       - redefinition of tau(i,i) (by a factor of ustar)
76       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
77       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
78       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
79       - replace
80         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
81         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
82         by
83         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
84         (changes results)
85       -> exf_bulkformulae v1.22,
86          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
87          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
88                    output.txt 1.63
89           offline_exf_seaice: output.seaicetd.txt 1.7
90           seaice_obcs: output.txt 1.10)
91      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
92       -> exf_bulkformulae v1.23,
93          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
94          and global_ocean.cs32x15.icedyn (only 11 matching digits)
95      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
96    o adjoint of exch-1:
97     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
98       (note: was already like this when using EXCH-2) and remove flow dir
99       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
100     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
101     - update pkg/exch2 diff list.
102    
103    checkpoint62g (2010/05/19)
104    o eesupp/src (exch-1):
105     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
106       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
107       (renamed to exch1_*rx_cube.F).
108     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
109       to call new exch1 S/R ; update Makefile and .cvsignore.
110     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
111       exch2_xy_rx later)
112      Note: after updating your code, need to run "make clean" in eesupp/src
113    o test experiment bottom_ctrl_5x5:
114       new output_adm.txt with fewer grdchk & less monitor output.
115    o model/src:
116      remove the call to ini_cori in initialise_varia.F (just keep the usual one
117       in initialise_fixed.F). More consistent with coriolis & horizontal grid
118       beeing treated in the same way (ini_grid is not called a 2nd time).
119    o pkg/exf:
120      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
121      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
122      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
123      - cosmetic changes to exf_bulkformulae.F to make it look more like
124        exf_bulk_largeyeager04.F
125    o eesupp/src (exch-1):
126      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
127      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
128        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
129        (even without using MPI).
130      - Message mode: move RecvAck setting (indicator of buffer being ready)
131        from send_put to recv_get S/R (was useless before, but not sure if
132        it's much more useful now);
133      - Switch the order of sync: MPI-proc 1rst and then threads;
134      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
135      - fix AD code for communication mode ='get' (but not used).
136    o model/src:
137      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
138      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
139    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
140    o pkg/ctrl: require a specific set of control variables and exf-flags for
141      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
142    o model/src:
143     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
144       1rst forward sweep, to avoid over-writing output files during recomputations
145       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
146     b) 2nd version:
147      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
148      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
149         writePickupAtEnd) + seaice & ptracers output;
150      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
151    o model/src:
152      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
153    o pkg/exch2:
154      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
155      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
156    o pkg/autodiff & exch2:
157      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
158      (for now, only if ALLOW_EXCH2 is defined).
159    o pkg/autodiff:
160      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
161        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
162       + clean-up comments (_RS is not always real*4)
163      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
164      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
165        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
166    o testreport (AD-tests):
167      no longer link files from dir "../input" (1rst link files from
168      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
169    
170    checkpoint62f (2010/04/29)
171    o model/src/the_main_loop.F:
172      adjust store directives for seaice evp and multicategory according to
173      pkg/ecco/the_main_loop.F
174    o adjoint:
175      global_sum_ad was incomplete (noted many times by many people ;)
176      nice description by Jean U. as follows:
177      * allreduce(var) in global_sum.F can be interpreted as
178        reduce(sum) followed by broadcast of sum.
179      * The adjoint of that is
180        sum(adjoint) followed by broadcast(summed adjoint value)
181        or in other words, allreduce(sum, adjoint vars)
182      We were missing the sum(adjoint)!
183      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
184      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
185      The fix should produce 16-digit accuracy between
186      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
187      multi-CPU single-tile (e.g. nSx=1, nPx-2)
188      We'll probably change this yet again shortly
189    o eesupp/src:
190      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
191  o pkg/icefront  o pkg/icefront
192    - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving    - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
193      specification of addmass array based on a 2D field, which is added      specification of addmass array based on a 2D field, which is added
