MPI_Get_version(3) MPI MPI_Get_version(3)NAME
MPI_Get_version - Return the version number of MPI
SYNOPSIS
int MPI_Get_version( int *version, int *subversion )
OUTPUT PARAMETERS
version
- Version of MPI
subversion
- Subversion of MPI
THREAD AND INTERRUPT SAFETY
This routine is both thread- and interrupt-safe. This means that this routine may safely be used by multiple threads and from within a
signal handler.
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.
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_Comm_set_errhandler (for communicators), MPI_File_set_errhandler (for files), and
MPI_Win_set_errhandler (for RMA windows). The MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated. 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; however, MPI implementations will attempt to continue whenever possible.
MPI_SUCCESS
- No error; MPI routine completed successfully.
