Merging changes on MAIN between checkpoint43 and checkpoint43a-release1mods
Command: cvs -q update -jcheckpoint43 -jcheckpoint43a-release1mods -d -P

These changes are most of the changes between c43 and c44 except those
that occured after "12:45 11 Jan 2002". As far as I can tell it is
checkpoint43 with the following mods:

  o fix bug in mom_vi_del2uv
  o select when filters are applied ; add options to zonal_filter (data.zonfilt)  o gmredi: fix Pb in the adiabatic form ; add options (.e.g. Bolus advection)
  o update AIM experiments (NCEP input files)
  o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
  o added some stuff for AD
  o Jamar wet-points

This update does not contain the following mods that are in checkpoint44

  o bug fix in pkg/generic_advdiff/
    - thread related bug, bi,bj arguments in vertical advection routines
  o some changes to pkg/autodiff, pkg/cost, pkg/exf, pkg/ecco,
    verification/carbon and model/src/ related to adjoint
  o some new Matlab scripts for diagnosing model density
    - utils/matlab/dens_poly3.m and ini_poly3.m

The list of exclusions is accurate based on a "cvs diff". The list of
inclusions is based on the record in doc/tag-index which may not be complete.

7     C | C preprocessor "execution environment" supporting |
8     C | flags. Use this file to set flags controlling the |
9     C | execution environment in which a model runs - as opposed |
10     C | to the dynamical problem the model solves. |
11     C | Note: Many options are implemented with both compile time|
12     C | and run-time switches. This allows options to be |
13     C | removed altogether, made optional at run-time or |
14     C | to be permanently enabled. This convention helps |
15     C | with the data-dependence analysis performed by the |
16     C | adjoint model compiler. This data dependency |
17     C | analysis can be upset by runtime switches that it |
18     C | is unable to recoginise as being fixed for the |
19     C | duration of an integration. |
20     C | A reasonable way to use these flags is to |
21     C | set all options as selectable at runtime but then |
22     C | once an experimental configuration has been |
23     C | identified, rebuild the code with the appropriate |
24     C | options set at compile time. |

30     C In general the following convention applies:
31     C ALLOW - indicates an feature will be included but it may
32     C CAN have a run-time flag to allow it to be switched
33     C on and off.
34     C If ALLOW or CAN directives are "undef'd" this generally
35     C means that the feature will not be available i.e. it
36     C will not be included in the compiled code and so no
37     C run-time option to use the feature will be available.
38     C
39     C ALWAYS - indicates the choice will be fixed at compile time
40     C so no run-time option will be present
41    
42     C Flag used to indicate whether Fortran formatted write
43     C and read are threadsafe. On SGI the routines can be thread
44     C safe, on Sun it is not possible - if you are unsure then
45     C undef this option.
46     #undef FMTFTN_IO_THREADSAFE

48     C-- Control MPI based parallel processing
49     #undef ALLOW_USE_MPI
50     #undef ALWAYS_USE_MPI
51    
52     C-- Control use of communication that might overlap computation.
53     C Under MPI selects/deselects "non-blocking" sends and receives.
54     #define ALLOW_ASYNC_COMMUNICATION
55     #undef ALLOW_ASYNC_COMMUNICATION
56     #undef ALWAYS_USE_ASYNC_COMMUNICATION
57     C-- Control use of communication that is atomic to computation.
58     C Under MPI selects/deselects "blocking" sends and receives.
59     #define ALLOW_SYNC_COMMUNICATION
60     #undef ALWAYS_USE_SYNC_COMMUNICATION
61    
62     C-- Control use of JAM routines for Artic network
63     C These invoke optimized versions of "exchange" and "sum" that
64     C utilize the programmable aspect of Artic cards.
65     #undef LETS_MAKE_JAM
66     #undef JAM_WITH_TWO_PROCS_PER_NODE
67    
68     C-- Control storage of floating point operands
69     C On many systems it improves performance only to use
70     C 8-byte precision for time stepped variables.
71     C Constant in time terms ( geometric factors etc.. )
72     C can use 4-byte precision, reducing memory utilisation and
73     C boosting performance because of a smaller working
74     C set size. However, on vector CRAY systems this degrades
75     C performance.
76     #define REAL4_IS_SLOW
77    
78     C-- Control use of "double" precision constants.
79     C Use D0 where it means REAL*8 but not where it means REAL*16
80     #define D0 d0
81    
82     C-- Control XY periodicity in processor to grid mappings
83     C Note: Model code does not need to know whether a domain is
84     C periodic because it has overlap regions for every box.
85     C Model assume that these values have been
86     C filled in some way.
