4      ==============================      ==============================
5    
6    checkpoint53
7    o stable checkpoint with up to date adjoint
8      TLM tests only run for 1st grdchk at the moment. Its unclear if
9      this is a code problem or a problem with resetting code for g_
10      variables that is being autogenerated wrong.
11      Otherwise:
12       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
13       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
14         are both still in chaos following their security messes.
15    
16    checkpoint52n_post
17    o various build (mostly genmake2) changes including:
18      - ability to build/run more easily within Cygwin and MacOS X
19      - more complicated Makefiles with a stronger dependence on Gnu Make
20    o pkg/seaice modifications
21      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
22        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
23        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
24      - changed proxy for geostrophic velocity and updated
25        verification/lab_sea/results/* accordingly
26      - removed ADI dynamic solver from pkg/seaice
27      - replaced all occurrences of 1/CSTICE or 1/CSUICE
28        they caused a segmentation fault under certain circumstances
29      - removed unused field WATR
30    o bug fix in exf-package:
31      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
32         now reflect that.
33    o small fixes in the cal-package:
34      - set reference date to first of January for the 'model'-calendar
35      - failing of cal_CheckDate in cal_FullDate now actually results in a
36        warning
37    o small modifications in exf-package to increase flexibility:
38      - change climtempfreeze from a constant to a runtime parameter that
39        is specified in data.exf_clim (default = -1.9)
40      - introduce runtime parameter windstressmax (default = 2.0) that is
41        specified in data.exf
42    o fix in pkg/thsice:
43      - update Evap (Tsf changes) to be consistent with Latent heat flux
44      - maintain snow precipitation unchanged (even if Tsf >=0).
45     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
46    
47    checkpoint52m_post
48    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
49      this does not change any of the results, because myIter=0 in swfrac always
50      lead to jwtype=2 (the default anyway), but the call makes little sense
51      as a default
52    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
53    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
54      atmospheric model (AIM) to use it ; add a "slab ocean" component.
55    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
56    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
57    o extending useSingleCpuIO option to work with new exch2 I/O format
58      - old-style, missing-tile I/O is still accessible by defining CPP
59        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
60    o monitor package can write to NetCDF files and/or STDOUT
61    o fix re-definition bug in MNC_GRID_INIT_ALL()
62    o doc/api_reference added
63      - a framework for building an API Reference Manual using all
64        the "protex" comments embedded in the code
65      - see pkg/generic_advdiff, pkg/mnc for examples
66    o MNC:
67      - make myThid the last argument for all subroutines
68      - new default for the grid files: NO halos
69      - add useMNC and other run-time flags
70      - separate per-file-group handling of the unlimited dimension
71      - early initialization of MNC w/ flags read at the eeboot stage
72        and lookup tables set in initialize_fixed
73      - write all MNC output to a freshly-created directory
74    o thermodynamics sea-ice (thsice) is now tested with testreport.
75    o test exp. advect_cs: use the standard cs32 grid ; update output.
76    o Added functionality to grdchk:
77      pick global i,j,k position (or nearest wet) where to perform check.
78    
79    checkpoint52l_post
80    o new land formulation:
81      a) use ground enthalpy as prognostic variable to ensure exact
82         energy conservation.
83      b) account for water temperature and for latent heat of freezing
84         in all processes (rain, run-off, ground storage)
85      c) compute surface and ground temperature implicitly.
86    o aim_v23 modification for new land model:
87      a) Treat separately land / ocean / sea-ice surface fluxes
88         to allow implicit computation of land & sea-ice surface temp.
89      b) add snow precipitation.
90    checkpoint52l_pre
91    
92    o fix problem (when 1 tile is empty) in min/max monitor.
93    o fix bug in timeAve (u,vZetatave in common block)
94    o no restoring terms under ice for pkg/seaice
95    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
96    o bug fix for pkg/seaice pickups
97    o change MNC call locations and add coordinate attributes
98    o mask vorticity at the corner ; affects global_ocean.cs output
99    o fix ini_curvilinear_grid ; test CS experiments with mpi
100    o aim.5l_cs: modify sea-ice fraction input file ; update output
101    o exf: Adding simple range check routine for exf fields after read
102    
103    checkpoint52k_post
104    o removed top-level directory "diags"
105      - we migrated these functions to pkg/timeave a long time ago
106    o fixed bug introduced in pkg/monitor
107    o accuracy ctrlprec = 32 insuffient for gradient checks using
108      averaged fields (I/O via cost_averages)
109      -> use ctrl.h in active_file*.F to control I/O precision.
110    o paramter list of CALL ADTHE_MAIN_LOOP
111    o added initial do_the_model_io to ecco
112    o set all ...Freq to zero after cost_final
113      taveFreq, dumpFreq, pChkptFreq
114    o MAIN and ECCO differentiability restored
115    
116    checkpoint52j_post
117    o fix nchklev in tamc.h for global_ocean...
118    o Bringing flow and store directives up-to-date
119    o Really weird thing!
120      call do_the_model_io from the_main_loop with parameters
121      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
122      TAF places a faulty re-call of initialise_varia
123      after cost_final call which should not be there!
124    checkpoint52j_pre
125    
126    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
127      error messages
128    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
129    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
130      debug output
131    o modfied mdsio_writefield.F to handle non-global files under exch2
132    o update AIM Cubed-Sphere exp (aim.5l_cs):
133      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
134    o update AIM Equatorial Channel exp:
135      use standard aim_v23 pkg and change the SST fields to be more realistic.
136    o globalFile now works with exch2
137    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
138      mon_vort3.F to make exch2 friendly with >1 tile per cube face
139    o limit timeave output for hi-res integrations
140    
141    checkpoint52i_post
142    o removed CPP_EEOPTIONS.h from verification/*/code

144    checkpoint52i_pre
145    
146    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
147      the old pkg/aim).
148    
149    checkpoint52h_pre
150    o shortened offending lines in exch2_send_rx?.template
151    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
152    o genmake2: add build & execute test for NetCDF code
153    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
154      old grid files, moved CPP_EEMACROS.h to pkg/exch2
155    o added useSingleCPUIO flag to monitor.F and mon_out.F
156    o added temporary hack for sea-ice dynamics on the cube:
157      metric terms are ignored and it is assumed that
158      there is no sea-ice on cube faces 1, 2, 4, and 5.
159    
160    checkpoint52f_post
161    o added exch2 cube routines to pkg/exch2
162    o modified hs94.cs-32x32x5 to use it
163    o added new grid files to hs94.cs-32x32x5
164    checkpoint52f_pre
165    
166    checkpoint52e_post
167    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
168      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
169    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
170      to work with implicit vertical advection and AB ;
171    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
172    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
173     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
174    checkpoint52e_pre
175    
176    o fix bug in impldiff when Nr=1 or Nr=2.
