4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/dic:
8      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
9        vectorization
10      - small bug fix in insol for the unlikely case of a cartesian grid
11      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
12        + now vectorize, which also removes adjoint recomputations;
13        + replace integer maksp1 by _RL maskp1
14        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
15    
16    checkpoint62i (2010/07/21)
17    o pkg/flt:
18      - with OBCS: stop floats which enter the OB region
19    o model/src:
20      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
21        for implicit vertical advection.
22    o pkg/seaice:
23     - account for melting in seaice age evolution.
24     - remove double counting of seaice ridging effect on seaice age.
25    
26    checkpoint62h (2010/06/18)
27    o pkg/exch2:
28     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
29    o tools/genmake2
30      - remove "-pdefault" option: redundant with the use of "packages.conf";
31      - remove file pkg/pkg_default : set the default as a pkg group
32        ("default_pkg_list") defined in pkg/pkg_groups;
33      - fix for case pkg/pkg_depend is missing (was hanging before);
34      - add option "-pgroups" to specify a different pkg_groups than the default.
35    o verification/adjustment.cs-32x32x1:
36       add a "minimal" set-up test (code_min & input_min) which only compiles
37       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
38    o tools/genmake2
39      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
40      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
41    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
42      files are nearly the same anyway.
43      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
44       - redefinition of tau(i,i) (by a factor of ustar)
45       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
46       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
47       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
48       - replace
49         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
50         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
51         by
52         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
53         (changes results)
54       -> exf_bulkformulae v1.22,
55          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
56          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
57                    output.txt 1.63
58           offline_exf_seaice: output.seaicetd.txt 1.7
59           seaice_obcs: output.txt 1.10)
60      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
61       -> exf_bulkformulae v1.23,
62          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
63          and global_ocean.cs32x15.icedyn (only 11 matching digits)
64      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
65    o adjoint of exch-1:
66     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
67       (note: was already like this when using EXCH-2) and remove flow dir
68       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
69     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
70     - update pkg/exch2 diff list.
71    
72    checkpoint62g (2010/05/19)
73    o eesupp/src (exch-1):
74     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
75       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
76       (renamed to exch1_*rx_cube.F).
77     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
78       to call new exch1 S/R ; update Makefile and .cvsignore.
79     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
80       exch2_xy_rx later)
81      Note: after updating your code, need to run "make clean" in eesupp/src
82    o test experiment bottom_ctrl_5x5:
83       new output_adm.txt with fewer grdchk & less monitor output.
84    o model/src:
85      remove the call to ini_cori in initialise_varia.F (just keep the usual one
86       in initialise_fixed.F). More consistent with coriolis & horizontal grid
87       beeing treated in the same way (ini_grid is not called a 2nd time).
88    o pkg/exf:
89      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
90      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
91      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
92      - cosmetic changes to exf_bulkformulae.F to make it look more like
93        exf_bulk_largeyeager04.F
94    o eesupp/src (exch-1):
95      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
96      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
97        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
98        (even without using MPI).
99      - Message mode: move RecvAck setting (indicator of buffer being ready)
100        from send_put to recv_get S/R (was useless before, but not sure if
101        it's much more useful now);
102      - Switch the order of sync: MPI-proc 1rst and then threads;
103      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
104      - fix AD code for communication mode ='get' (but not used).
105    o model/src:
106      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
107      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
108    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
109    o pkg/ctrl: require a specific set of control variables and exf-flags for
110      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
111    o model/src:
112     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
113       1rst forward sweep, to avoid over-writing output files during recomputations
114       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
115     b) 2nd version:
116      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
117      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
118         writePickupAtEnd) + seaice & ptracers output;
119      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
120    o model/src:
121      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
122    o pkg/exch2:
123      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
124      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
125    o pkg/autodiff & exch2:
126      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
127      (for now, only if ALLOW_EXCH2 is defined).
128    o pkg/autodiff:
129      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
130        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
131       + clean-up comments (_RS is not always real*4)
132      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
133      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
134        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
135    o testreport (AD-tests):
136      no longer link files from dir "../input" (1rst link files from
137      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
138    
139    checkpoint62f (2010/04/29)
140  o model/src/the_main_loop.F:  o model/src/the_main_loop.F:
