MPI_Get_version(3) Open MPI MPI_Get_version(3)
NAME
MPI_Get_version - Returns the version of the standard corresponding to
the current implementation.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Get_version(int *version, int *subversion)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_GET_VERSION(VERSION, SUBVERSION, IERROR)
INTEGER VERSION, SUBVERSION, IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Get_version(version, subversion, ierror)
INTEGER, INTENT(OUT) :: version, subversion
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
C++ Syntax
#include <mpi.h>
void Get_version(int& version, int& subversion)
OUTPUT PARAMETERS
version The major version number of the corresponding standard (inte-
ger).
subversion
The minor version number of the corresponding standard (inte-
ger).
IERROR Fortran only: Error status (integer).
DESCRIPTION
Since Open MPI is MPI 3.1 compliant, this function will return a ver-
sion value of 3 and a subversion value of 1 for this release.
NOTE
MPI_Get_version is one of the few functions that can be called before
MPI_Init and after MPI_Finalize.
ERRORS
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to
MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI::Exception object.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with
MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
may be used to cause error values to be returned. Note that MPI does
not guarantee that an MPI program can continue past an error.
