MPI_Get_version

:ref:`MPI_Get_version` |mdash| 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

OUTPUT PARAMETERS

  • version : The major version number of the corresponding standard (integer).
  • subversion : The minor version number of the corresponding standard (integer).
  • ierror : Fortran only: Error status (integer).

DESCRIPTION

Since Open MPI |ompi_ver| is MPI-|mpi_standard_version| compliant (see :ref:`this page for more details about Open MPI standards conformance <release-notes-mpi-standard-conformance-label>`) this function will return a version value of |mpi_standard_major_version| and a subversion value of |mpi_standard_minor_version| for this release.

NOTE

:ref:`MPI_Get_version` is one of the few functions that can be called before :ref:`MPI_Init` and after :ref:`MPI_Finalize`.
