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_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++ func-
       tions 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.

NAME

       MPI_Get_version -  Return the version number of MPI

SYNOPSIS

       int MPI_Get_version( int *version, int *subversion )

OUTPUT PARAMETERS

       version
	      - Version of MPI
       subversion
	      - Subversion of MPI

THREAD AND INTERRUPT SAFETY

       This  routine  is  both	thread- and interrupt-safe.  This means that this routine may safely be used by multiple threads and from within a
       signal handler.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument  list.   ierr
       is  an integer and has the same meaning as the return value of the routine in C.  In Fortran, MPI routines are subroutines, and are invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran  routines	in
       the  last  argument.  Before the value is returned, the current MPI error handler is called.  By default, this error handler aborts the MPI
       job.  The error handler may  be	changed  with  MPI_Comm_set_errhandler	(for  communicators),  MPI_File_set_errhandler	(for  files),  and
       MPI_Win_set_errhandler  (for  RMA  windows).   The  MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated.  The predefined
       error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.  Note that MPI does not guarentee that an MPI program can
       continue past an error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
