5      ==============================      ==============================
6    
7    o add brackets in multi-terms sum to get same truncation, independent of
8      the face number (manage to get exactly same value of gU,gV at the cs-edge)
9      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
10    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
11      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
12      a maximum grid-scale Reynolds number.  Also, changes all length calculations
13      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
14      Suggested values of viscosity parameters found in mom_calc_visc.
15      Many new viscosity diagnostics available.
16    
17    checkpoint57s_post
18    o Add clearing-house for viscosity calculations, mom_calc_visc and
19      correct numerous bugs in LeithD and Smagorinsky discretizations.  
20      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
21      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
22      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
23      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
24      The Strain-Tension form is now called with useStrainTensonVisc=.true.
25      ViscAhStrain and viscAhTension are now retired.
26    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
27    o In response to JMC's bug report, genmake2 now ignores any soft-links
28      that it finds in the *current* directory when searching for files.
29      Soft-links found in any other source directories will still work as
30      they did before.
31    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
32      a C routine to unlimit the stack size
33    o mnc-ify pkg/aim snapshot vars
34    o mnc-ify pkg/land as requested by Daniel
35    o various changes to mnc including:
36      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
37      - output can now be grouped so that all files within a group
38          change the ITER portion of their names in lock-step together
39      - can now read ("global") PER-FACE (in addition to PER-TILE) files
40          and works with both EXCH1 and EXCH2 (but needs more testing)
41      - writing works for all verification test cases w/ g77 on Linux
42    
43    checkpoint57r_post
44    o make MNC variable initialization happen earlier
45    o add diagnostics for (almost) each term of the momentum Eq.
46    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
47    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
48    o remove MINIMAL_TAVE_OUTPUT option ;
49      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
50    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
51      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
52    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
53    o add time-dependent SST, SSS control
54    o cost terms in ecco/ modularized (new cost_generic.F)
55    o cost_averages routines are modularized (new cost_averagesgeneric.F)
56    o new infrastructure for seaice model vs. obs misfits in seaice/
57      * driver from the_main_loop.F is seaice_cost_driver.F
58      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
59      * gradient check in Exp. 6a of natl_box_adjoint/
60    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
61      (see README file)
62    
63    checkpoint57q_post
64    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
65    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
66      - bug was reported by Jean-Michel and Ian Fenty
67    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
68      update exp. cpl_aim+ocn output.
69    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
70      Needed for high-res. runs with large global files
71      to be able to limit tapelev size
72    o Changed some tests for adjoint:
73      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
74      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
75      * global_ocean.90x40x15/ back to default 3-level checkpointing
76    o Modifications to enable scripted COMMON to MODULE conversion
77      * verification/OpenAD/code/ has necessary scripts and description;
78      * converts, compiles and runs successfully;
79    
80  checkpoint57p_post  checkpoint57p_post
81  o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F  o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
82  o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED  o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
