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
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.
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.
