MPI_Initialized(3) LAM/MPI MPI_Initialized(3)
MPI_Initialized - Indicates whether MPI_Init has been called.
int MPI_Initialized(int *flag)
flag - Flag is true (1) if MPI_Init has been called and false (0) otherwise.
This function always returns MPI_SUCCESS
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked
with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
The LAM Team would like the thank the MPICH Team for the handy program to generate man pages ("doctext" from ftp://ftp.mcs.anl.gov/pub/sow-
ing/sowing.tar.gz ), the initial formatting, and some initial text for most of the MPI-1 man pages.
