NAME¶
MPI_Get_version - Returns the version of the standard corresponding to
the current implementation.
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.
