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.

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

29 C In general the following convention applies:
30 C ALLOW - indicates an feature will be included but it may
31 C CAN have a run-time flag to allow it to be switched
32 C on and off.
33 C If ALLOW or CAN directives are "undef'd" this generally
34 C means that the feature will not be available i.e. it
35 C will not be included in the compiled code and so no
36 C run-time option to use the feature will be available.
37 C
38 C ALWAYS - indicates the choice will be fixed at compile time
39 C so no run-time option will be present
41 C Flag used to indicate whether Fortran formatted write
42 C and read are threadsafe. On SGI the routines can be thread
43 C safe, on Sun it is not possible - if you are unsure then
44 C undef this option.
47 C-- Control MPI based parallel processing
48 #undef ALLOW_USE_MPI
49 #undef ALWAYS_USE_MPI
51 C-- Control use of communication that might overlap computation.
52 C Under MPI selects/deselects "non-blocking" sends and receives.
56 C-- Control use of communication that is atomic to computation.
57 C Under MPI selects/deselects "blocking" sends and receives.
61 C-- Control use of JAM routines for Artic network
62 C These invoke optimized versions of "exchange" and "sum" that
63 C utilize the programmable aspect of Artic cards.
64 #undef LETS_MAKE_JAM
67 C-- Control storage of floating point operands
68 C On many systems it improves performance only to use
69 C 8-byte precision for time stepped variables.
70 C Constant in time terms ( geometric factors etc.. )
71 C can use 4-byte precision, reducing memory utilisation and
72 C boosting performance because of a smaller working
73 C set size. However, on vector CRAY systems this degrades
74 C performance.
75 #define REAL4_IS_SLOW
77 C-- Control use of "double" precision constants.
78 C Use D0 where it means REAL*8 but not where it means REAL*16
79 #define D0 d0
81 C-- Control XY periodicity in processor to grid mappings
82 C Note: Model code does not need to know whether a domain is
83 C periodic because it has overlap regions for every box.
84 C Model assume that these values have been
85 C filled in some way.
