MPI_Get_version(3OpenMPI)                                                          MPI_Get_version(3OpenMPI)



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_Final-ize. MPI_Finalize.
       ize.


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.
