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 (integer).

       subversion
                 The minor version number of the corresponding standard (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       Since  Open  MPI  is  MPI  3.1 compliant, this function will return a version 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++ functions 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.
