5      ==============================      ==============================
6    
7    checkpoint57s_post
8    o Add clearing-house for viscosity calculations, mom_calc_visc and
9      correct numerous bugs in LeithD and Smagorinsky discretizations.  
10      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
11      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
12      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
13      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
14      The Strain-Tension form is now called with useStrainTensonVisc=.true.
15      ViscAhStrain and viscAhTension are now retired.
16    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
17    o In response to JMC's bug report, genmake2 now ignores any soft-links
18      that it finds in the *current* directory when searching for files.
19      Soft-links found in any other source directories will still work as
20      they did before.
21    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
22      a C routine to unlimit the stack size
23    o mnc-ify pkg/aim snapshot vars
24    o mnc-ify pkg/land as requested by Daniel
25    o various changes to mnc including:
26      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
27      - output can now be grouped so that all files within a group
28          change the ITER portion of their names in lock-step together
29      - can now read ("global") PER-FACE (in addition to PER-TILE) files
30          and works with both EXCH1 and EXCH2 (but needs more testing)
31      - writing works for all verification test cases w/ g77 on Linux
32    
33    checkpoint57r_post
34    o make MNC variable initialization happen earlier
35    o add diagnostics for (almost) each term of the momentum Eq.
36    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
37    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
38    o remove MINIMAL_TAVE_OUTPUT option ;
39      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
40    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
41      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
42    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
43    o add time-dependent SST, SSS control
44    o cost terms in ecco/ modularized (new cost_generic.F)
45    o cost_averages routines are modularized (new cost_averagesgeneric.F)
46    o new infrastructure for seaice model vs. obs misfits in seaice/
47      * driver from the_main_loop.F is seaice_cost_driver.F
48      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
49      * gradient check in Exp. 6a of natl_box_adjoint/
50    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
51      (see README file)
52    
53    checkpoint57q_post
54    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
55    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
56      - bug was reported by Jean-Michel and Ian Fenty
57    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
58      update exp. cpl_aim+ocn output.
59    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
60      Needed for high-res. runs with large global files
61      to be able to limit tapelev size
62    o Changed some tests for adjoint:
63      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
64      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
65      * global_ocean.90x40x15/ back to default 3-level checkpointing
66    o Modifications to enable scripted COMMON to MODULE conversion
67      * verification/OpenAD/code/ has necessary scripts and description;
68      * converts, compiles and runs successfully;
69    
70    checkpoint57p_post
71    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
72    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
73      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
74    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
75    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
76      (was already the case for dissipation with mom_vecinv,
77       and also the case for grad.PhiHyd when staggered-timeStep)
78      This will allow to put dissipation out-off the AB time-stepping.
79     Unfortunately, affects truncation error. Update output of exp. that "fails"
80      (cg2d matching number) and leave the others for later: front_relax(10),
81      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
82      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
83    
84    checkpoint57o_post
85    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
86      (2) its ready to be documented during the 20050801 DocFest
87    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
88      for ideal_2D_oce and lab_sea on linux_ia32_g77
89    o set to #undef CTRL_SET_OLD_MAXCVARS_30
90      in global1x1_tot/code_seaice_adj to access indices 32, 33
91      (worth another tag)
92    
93    checkpoint57n_post
94    o adding precip control xx_precip 32
95    o adding swflux control xx_swflux 33
96    o Replacing 10 forcing penalty cost routines by 1 generic.
97    o Implementing partitioning in time-mean and variable adjustment
98      for atmos. state.
99    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
100    o in natl_box_adjoint:
101      * updated exp 1 to 10
102        (but does not have time-mean vs. variable split results yet)
103    o updated global1x1/*_seaice_adj/
104      to incorporate latest changes
105    o enable useSingleCpuIO for mdsio vector routines
106      (applies in particular to tapelev I/O)
107    o removed inefficient K-loop in all active_file*control*.F
108    
109    checkpoint57m_post
110    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
111      and advect_cs (use EXCH-2 and standard cs-32 grid files).
112    o pkg/exch2: filling of face-corner halo regions is optional
113      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
114    
115    checkpoint57l_post
116     tag before updating tutorials (pre-release-2)
117    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
118       for output and interpolation of input fields onto model grid)
119    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
120       Affects results of exp. rotating_tank ; update output.txt.
121    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
122          and taking the square quantity and/or using a fraction-weight field.
123    o fix aim_diagnostics_init.F mate numbers.
124    o add mnc output capability to diagnostics/diagstat and update
125      our cvsignore files for the ACSII output generated
126    
127    checkpoint57k_post
128    o lab_sea now uses diagnostics package and provides a suite of
129      new EXF diagnostics output.
130    
131    checkpoint57j_post
132    o exf
133      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
134        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
135        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
136      * extended diagnostics output
137        - now includes all EXF variables
138        - hs, hl moved to common block
139        - separate S/R for diagnostics, called after ctrl vector is added
140        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
141        - EXFqnet contains true Qnet (i.e. includes qsw)
142      * updated verif. lab_sea, global_with_exf
143      * Rearranging hflux (exf_mapfields -> exf_getforcing)
144        to ensure that diagnostics sees a true EXFqnet
145    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
146    o diagnostics pkg: change pointers so that 1 diagnostic can be used
147      several times with different frequencies.
148    o mnc-ify the thsice package as requested by Daniel Enderton
149      - the monitor--MNC output needs work
150      - many attributes need to be added (most are currently blank)
151    o mnc-ify theaim_v23 package as requested by Daniel Enderton
152      - many attributes need to be added (most are currently blank)
153    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
154    o add Sadourny like discretization to the 4th.O vorticity advection scheme
155    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
156      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
157         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
158    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
159     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
160    
161    checkpoint57i_post
162    o Diagnostics package was changed: diagnostic allocation is now deactivated
163      by setting an empty file name in the namelist (used to be by setting 0 frequency)
164    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
165      add 1rst Order upwind vertical Shear.
166    o add a quick fix for A/B checkpointing in OFFLINE mode
167    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
168      end-run around the C/Fortran linking horror in eesup/src/timers.F
169    o added pkg/runclock: allows user to terminate run based on wall clock
170    o added non-hydrostatic scaling parameter: nh_am2
171    o pkg/my82: futile attempt to make results compiler-independent by adding
172      some "_d 0", etc. no effect.
173    o for mnc output, fill the 'T' coordinate var with myTime and create a
174      separate 'iter' variable for iteration count
175    o pkg/diagnostics:
176      add new capability: output of Global/Regional & per-level statistics ;
177      tested against monitor output (including land & thSIce) on various exp.
178    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
