NAME

MPI_Abort - Abort and return an exit code

SYNOPSIS

#include <mpi.h> 
int MPI_Abort(MPI_Comm comm , int errcode ); 
#include <pmpi.h> 
int PMPI_Abort(MPI_Comm comm , int errcode ); 

INPUT PARAMETERS

comm - communicator (unused) (handle)

errcode - error code to return to operating system (integer)

DESCRIPTION

The MPI_Abort() function is used to abort from a program. No clean shutdown is performed. The error code errcode is returned to the operating system by the root rank of MPI_COMM_WORLD. Even though a communicator, comm is specified as a parameter to this function, it is unused. However, using MPI_COMM_NULL will return an error as required by the MPI specification.

PMPI_Abort() is the profiling version of this function.

ERRORS

All MPI routines except for MPI_Wtime and MPI_Wtick return an error value. The the current MPI error handler is invoked if this 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.

MPI_SUCCESS - No error;

MPI_ERR_COMM - Invalid communicator.
