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

       INCLUDE 'mpif.h'
       MPI_GET_VERSION(VERSION, SUBVERSION, IERROR)
            INTEGER   VERSION, SUBVERSION, 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  2.0  compliant,  this  function  will  return  a
       version value of 2 and a subversion value of 0 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.
