11 C | This routine is called from the high-level wrapper |
12 C | after multi-process paralle processing has started but |
13 C | before multi-threaded parallelism. THe routine reads an |
14 C | an "execution environment" input parameter file holding |
15 C | information about the number of threads at run-time. |

42 C-- For now these options are fixed as the code does
43 C not fully support features for overlapping communication
44 C and computation.

47 C-- Text map plots of fields ignore exact zero values
48 printMapIncludesZeros = .FALSE.
49
50 C-- The remaining parameters here are set to default values.
51 C-- and then any different values are read from an input
52 C-- file called "eedata".
53 C The defaults set here are for serial execution.
54 C
55 C nTx and nTy are the number of threads in the X and Y
56 C directions.
57 C nSx/nTx and nSy/nTy be whole numbers at present.
58 C
59 C notUsingXPeriodicity and notUsingYPeriodicity affect
60 C the identifying of neighbor processes in a multi-process
61 C mode. On the whole the numerical model code should not
62 C customise itself based on these numbers as they may be
63 C removed if they do not prove useful.
64 C
65 C usingMPI is a flag which controls whether MPI message
66 C passing library calls are actually made. Note that under
67 C MPI it is necessary to start a program a special way -
68 C normally using a command of the form
69 C % mpirun program_name
70 C If usingMPI is set to TRUE but % mpirun .... was not
71 C used to launch the program then an internal MPI error
72 C may be generated when the first MPI call ( CALL MPI_Init )
73 C is made.
