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 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.
