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.
