NAME

MPI_Get_version - Get the current version of the MPI library

SYNOPSIS

#include <mpi.h> int MPI_Get_version(int *version , int *subversion );

#include <pmpi.h> int PMPI_Get_version(int *version , int *subversion );

#include <mpi.h> void MPI::Get_version(int &version , int &subversion );

INCLUDE 'mpif.h' MPI_GET_VERSION(version , subversion , ierr ) INTEGER version , subversion , ierr

OUTPUT PARAMETERS

version - major version number of the MPI library (integer)

subversion - minor version number of the MPI library (integer)

DESCRIPTION

The MPI_Get_version() function is used to determine at runtime the version of the MPI library. The version and subversion variables are filled with the major and minor version numbers respectively. At compile-time this information is within the MPI_VERSION and MPI_SUBVERSION preprocessor variables.

PMPI_Get_version() is the profiling version of this function.

ERRORS

All MPI routines except for MPI_Wtime and MPI_Wtick return an error code. The the current MPI error handler is invoked if the return value is not MPI_SUCCESS. The default error handler aborts, but this may be changed with by using the MPI_Errhandler_set() function. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned instead. Note that MPI does not guarentee that an MPI program can continue past an error. In this implementation, all errors except MPI_ERR_INTERN or MPI_ERR_OTHER should always be recoverable.

In C, the error code is passed as the return value. In FORTRAN, all functions have an parameter ierr which returns the error code. MPI C++ functions do not directly return an error code. However, C++ users may want to use the MPI::ERRORS_THROW_EXCEPTIONS handler. This will throw an MPI::Exception with the corresponding error code. To prevent exceptions from being raised from within C and Fortran code, they will see all error return values as MPI_ERR_PENDING when this handler is chosen. In this implementation, call MPI::throw_exception() to throw the correct exception if this occurs.

MPI_SUCCESS - No error;

MPI_ERR_PENDING - Pending exception;

MPI_ERR_ARG - Invalid pointer.
