5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o fix bug in non-linear free-surf side-drag ; generate new output for
8  o moved ptracer ctrl index 17 -> 32    global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
9    o make mnc honor the writeBinaryPrec flag for most kinds of output
10    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
11    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
12      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
13    o add brackets in multi-terms sum to get same truncation, independent of
14      the face number (manage to get exactly same value of gU,gV at the cs-edge)
15      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
16    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
17      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
18      a maximum grid-scale Reynolds number.  Also, changes all length calculations
19      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
20      Suggested values of viscosity parameters found in mom_calc_visc.
21      Many new viscosity diagnostics available.
22    
23    checkpoint57s_post
24    o Add clearing-house for viscosity calculations, mom_calc_visc and
25      correct numerous bugs in LeithD and Smagorinsky discretizations.  
26      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
27      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
28      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
29      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
30      The Strain-Tension form is now called with useStrainTensonVisc=.true.
31      ViscAhStrain and viscAhTension are now retired.
32    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
33    o In response to JMC's bug report, genmake2 now ignores any soft-links
34      that it finds in the *current* directory when searching for files.
35      Soft-links found in any other source directories will still work as
36      they did before.
37    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
38      a C routine to unlimit the stack size
39    o mnc-ify pkg/aim snapshot vars
40    o mnc-ify pkg/land as requested by Daniel
41    o various changes to mnc including:
42      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
43      - output can now be grouped so that all files within a group
44          change the ITER portion of their names in lock-step together
45      - can now read ("global") PER-FACE (in addition to PER-TILE) files
46          and works with both EXCH1 and EXCH2 (but needs more testing)
47      - writing works for all verification test cases w/ g77 on Linux
48    
49    checkpoint57r_post
50    o make MNC variable initialization happen earlier
51    o add diagnostics for (almost) each term of the momentum Eq.
52    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
53    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
54    o remove MINIMAL_TAVE_OUTPUT option ;
55      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
56    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
57      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
58    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
59    o add time-dependent SST, SSS control
60    o cost terms in ecco/ modularized (new cost_generic.F)
61    o cost_averages routines are modularized (new cost_averagesgeneric.F)
62    o new infrastructure for seaice model vs. obs misfits in seaice/
63      * driver from the_main_loop.F is seaice_cost_driver.F
64      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
65      * gradient check in Exp. 6a of natl_box_adjoint/
66    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
67      (see README file)
68    
69    checkpoint57q_post
70    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
71    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
72      - bug was reported by Jean-Michel and Ian Fenty
73    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
74      update exp. cpl_aim+ocn output.
75    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
76      Needed for high-res. runs with large global files
77      to be able to limit tapelev size
78    o Changed some tests for adjoint:
79      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
80      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
81      * global_ocean.90x40x15/ back to default 3-level checkpointing
82    o Modifications to enable scripted COMMON to MODULE conversion
83      * verification/OpenAD/code/ has necessary scripts and description;
84      * converts, compiles and runs successfully;
85    
86    checkpoint57p_post
87    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
88    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
89      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
90    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
91    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
92      (was already the case for dissipation with mom_vecinv,
93       and also the case for grad.PhiHyd when staggered-timeStep)
94      This will allow to put dissipation out-off the AB time-stepping.
95     Unfortunately, affects truncation error. Update output of exp. that "fails"
96      (cg2d matching number) and leave the others for later: front_relax(10),
97      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
98      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
99    
100    checkpoint57o_post
101    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
102      (2) its ready to be documented during the 20050801 DocFest
103    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
104      for ideal_2D_oce and lab_sea on linux_ia32_g77
105    o set to #undef CTRL_SET_OLD_MAXCVARS_30
106      in global1x1_tot/code_seaice_adj to access indices 32, 33
107      (worth another tag)
108    
109    checkpoint57n_post
110    o adding precip control xx_precip 32
111    o adding swflux control xx_swflux 33
112    o Replacing 10 forcing penalty cost routines by 1 generic.
113    o Implementing partitioning in time-mean and variable adjustment
114      for atmos. state.
115    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
116  o in natl_box_adjoint:  o in natl_box_adjoint:
117    * updated: results_bulk/    * updated exp 1 to 10
118    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
119    o updated global1x1/*_seaice_adj/
120      to incorporate latest changes
121    o enable useSingleCpuIO for mdsio vector routines
122      (applies in particular to tapelev I/O)
123    o removed inefficient K-loop in all active_file*control*.F
124    
125  checkpoint57m_post  checkpoint57m_post
126  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
