5      ==============================      ==============================
6    
7  o pkg/exf/exf_bulk_largeyeager04.F: rewrite for better vectorization, changes  
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    o adjoint of exch-1:
32     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
33       (note: was already like this when using EXCH-2) and remove flow dir
34       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
35     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
36     - update pkg/exch2 diff list.
37    
38    checkpoint62g (2010/05/19)
39    o eesupp/src (exch-1):
40     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
41       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
42       (renamed to exch1_*rx_cube.F).
43     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
44       to call new exch1 S/R ; update Makefile and .cvsignore.
45     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
46       exch2_xy_rx later)
47      Note: after updating your code, need to run "make clean" in eesupp/src
48    o test experiment bottom_ctrl_5x5:
49       new output_adm.txt with fewer grdchk & less monitor output.
50    o model/src:
51      remove the call to ini_cori in initialise_varia.F (just keep the usual one
52       in initialise_fixed.F). More consistent with coriolis & horizontal grid
53       beeing treated in the same way (ini_grid is not called a 2nd time).
54    o pkg/exf:
55      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
56    global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated    global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
57      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
58      - cosmetic changes to exf_bulkformulae.F to make it look more like
59        exf_bulk_largeyeager04.F
60  o eesupp/src (exch-1):  o eesupp/src (exch-1):
