5      ==============================      ==============================
6    o Add clearing-house for viscosity calculations, mom_calc_visc and
7      correct numerous bugs in LeithD and Smagorinsky discretizations.  
8      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
9      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
10      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
11      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
12      The Strain-Tension form is now called with useStrainTensonVisc=.true.
13      ViscAhStrain and viscAhTension are now retired.
14    o  diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
15    o In response to JMC's bug report, genmake2 now ignores any soft-links
16      that it finds in the *current* directory when searching for files.
17      Soft-links found in any other source directories will still work as
18      they did before.
19    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
20      a C routine to unlimit the stack size
21    o mnc-ify pkg/aim snapshot vars
22    o mnc-ify pkg/land as requested by Daniel
23    o various changes to mnc including:
24      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
25      - output can now be grouped so that all files within a group
26          change the ITER portion of their names in lock-step together
27      - can now read ("global") PER-FACE (in addition to PER-TILE) files
28          and works with both EXCH1 and EXCH2 (but needs more testing)
29      - writing works for all verification test cases w/ g77 on Linux
30    
31    checkpoint57r_post
32    o make MNC variable initialization happen earlier
33    o add diagnostics for (almost) each term of the momentum Eq.
34    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
35    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
36    o remove MINIMAL_TAVE_OUTPUT option ;
37      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
38    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
39      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
40    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
41    o add time-dependent SST, SSS control
42    o cost terms in ecco/ modularized (new cost_generic.F)
43    o cost_averages routines are modularized (new cost_averagesgeneric.F)
44    o new infrastructure for seaice model vs. obs misfits in seaice/
45      * driver from the_main_loop.F is seaice_cost_driver.F
46      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
47      * gradient check in Exp. 6a of natl_box_adjoint/
48    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
49      (see README file)
50    
51    checkpoint57q_post
52    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
53    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
54      - bug was reported by Jean-Michel and Ian Fenty
55    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
56      update exp. cpl_aim+ocn output.
57    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
58      Needed for high-res. runs with large global files
59      to be able to limit tapelev size
60    o Changed some tests for adjoint:
61      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
62      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
63      * global_ocean.90x40x15/ back to default 3-level checkpointing
64    o Modifications to enable scripted COMMON to MODULE conversion
65      * verification/OpenAD/code/ has necessary scripts and description;
66      * converts, compiles and runs successfully;
67    
68    checkpoint57p_post
69    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
70    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
71      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
72    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
73    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
74      (was already the case for dissipation with mom_vecinv,
75       and also the case for grad.PhiHyd when staggered-timeStep)
76      This will allow to put dissipation out-off the AB time-stepping.
77     Unfortunately, affects truncation error. Update output of exp. that "fails"
78      (cg2d matching number) and leave the others for later: front_relax(10),
79      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
80      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
81    
82    checkpoint57o_post
83  o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and  o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
84    (2) its ready to be documented during the 20050801 DocFest    (2) its ready to be documented during the 20050801 DocFest
85  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
86    for ideal_2D_oce and lab_sea on linux_ia32_g77    for ideal_2D_oce and lab_sea on linux_ia32_g77
87    o set to #undef CTRL_SET_OLD_MAXCVARS_30
88      in global1x1_tot/code_seaice_adj to access indices 32, 33
89      (worth another tag)
90    
91  checkpoint57n_post  checkpoint57n_post
92  o adding precip control xx_precip 32  o adding precip control xx_precip 32
