15     C | SUBROUTINE EESET_PARMS
16     C | o Routine to set model "parameters"
17     C *==========================================================*
18     C | This routine is called from the high-level wrapper
19     C | after multi-process paralle processing has started but
20     C | before multi-threaded parallelism. THe routine reads an
21     C | an "execution environment" input parameter file holding
22     C | information about the number of threads at run-time.

52     C-- For now these options are fixed as the code does
53     C not fully support features for overlapping communication
54     C and computation.

57     C-- Text map plots of fields ignore exact zero values
58     printMapIncludesZeros = .FALSE.
59    
60     C-- The remaining parameters here are set to default values.
61     C-- and then any different values are read from an input
62     C-- file called "eedata".
63     C The defaults set here are for serial execution.
64     C
65     C nTx and nTy are the number of threads in the X and Y
66     C directions.
67     C nSx/nTx and nSy/nTy be whole numbers at present.
68     C
69     C notUsingXPeriodicity and notUsingYPeriodicity affect
70     C the identifying of neighbor processes in a multi-process
71     C mode. On the whole the numerical model code should not
72     C customise itself based on these numbers as they may be
73     C removed if they do not prove useful.
74     C
75     C usingMPI is a flag which controls whether MPI message
76     C passing library calls are actually made. Note that under
77     C MPI it is necessary to start a program a special way -
78     C normally using a command of the form
79     C % mpirun program_name
80     C If usingMPI is set to TRUE but % mpirun .... was not
81     C used to launch the program then an internal MPI error
82     C may be generated when the first MPI call ( CALL MPI_Init )
83     C is made.
84     C
85     C useCoupler is a flag which controls communications with other
86     C model components through a coupler interface.
