8    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
9      files are nearly the same anyway.
10      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
11       - redefinition of tau(i,i) (by a factor of ustar)
12       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
13       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
14       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
15       - replace
16         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
17         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
18         by
19         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
20         (changes results)
21       -> exf_bulkformulae v1.22,
22          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
23          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
24                    output.txt 1.63
25           offline_exf_seaice: output.seaicetd.txt 1.7
26           seaice_obcs: output.txt 1.10)
27      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
28       -> exf_bulkformulae v1.23,
29          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
30          and global_ocean.cs32x15.icedyn (only 11 matching digits)
31      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
32    o adjoint of exch-1:
33     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
34       (note: was already like this when using EXCH-2) and remove flow dir
35       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
36     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
37     - update pkg/exch2 diff list.
38    
39    checkpoint62g (2010/05/19)
40    o eesupp/src (exch-1):
41     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
42       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
43       (renamed to exch1_*rx_cube.F).
44     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
45       to call new exch1 S/R ; update Makefile and .cvsignore.
46     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
47       exch2_xy_rx later)
48      Note: after updating your code, need to run "make clean" in eesupp/src
49    o test experiment bottom_ctrl_5x5:
50       new output_adm.txt with fewer grdchk & less monitor output.
51    o model/src:
52      remove the call to ini_cori in initialise_varia.F (just keep the usual one
53       in initialise_fixed.F). More consistent with coriolis & horizontal grid
54       beeing treated in the same way (ini_grid is not called a 2nd time).
55    o pkg/exf:
56      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
57      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
58      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
59      - cosmetic changes to exf_bulkformulae.F to make it look more like
60        exf_bulk_largeyeager04.F
61    o eesupp/src (exch-1):
62      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
63      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
64        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
65        (even without using MPI).
66      - Message mode: move RecvAck setting (indicator of buffer being ready)
67        from send_put to recv_get S/R (was useless before, but not sure if
68        it's much more useful now);
69      - Switch the order of sync: MPI-proc 1rst and then threads;
70      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
71      - fix AD code for communication mode ='get' (but not used).
72    o model/src:
73      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
74      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
75    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
76    o pkg/ctrl: require a specific set of control variables and exf-flags for
77      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
78    o model/src:
79     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
80       1rst forward sweep, to avoid over-writing output files during recomputations
81       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
82     b) 2nd version:
83      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
84      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
85         writePickupAtEnd) + seaice & ptracers output;
86      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
87    o model/src:
88      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
89    o pkg/exch2:
90      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
91      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
92  o pkg/autodiff & exch2:  o pkg/autodiff & exch2:
93    process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF    process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
94    (for now, only if ALLOW_EXCH2 is defined).    (for now, only if ALLOW_EXCH2 is defined).
95  o pkg/autodiff:  o pkg/autodiff:
96    - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F    - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
97      (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.      (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
98     + clean-up comments (_RS is not always real*4)     + clean-up comments (_RS is not always real*4)
99    - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)    - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
