MPI_Init_thread
Initialize the MPI execution environment
Synopsis
int MPI_Init_thread( int *argc, char ***argv, int required, int *provided )
Input Parameters
- argc
- Pointer to the number of arguments
- argv
- Pointer to the argument vector
- required
- Level of desired thread support
Output Parameter
- provided
- Level of provided thread support
Command line arguments
MPI specifies no command-line arguments but does allow an MPI
implementation to make use of them. See MPI_INIT for a description of
the command line arguments supported by MPI_INIT and MPI_INIT_THREAD.
Notes
Note that the Fortran binding for this routine does not have the argc and
argv arguments. (MPI_INIT_THREAD(required, provided, ierror))
Errors
All MPI routines (except MPI_Wtime and MPI_Wtick) return an error value;
C routines as the value of the function and Fortran routines in the last
argument. Before the value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job. The error handler
may be changed with MPI_Errhandler_set; the predefined error handler
MPI_ERRORS_RETURN may be used to cause error values to be returned.
Note that MPI does not guarentee that an MPI program can continue past
an error.
- MPI_SUCCESS
- No error; MPI routine completed successfully.
