Terminates MPI execution environment


#include "mpi.h"
int MPI_Abort( comm, errorcode )
MPI_Comm         comm;
int              errorcode;

Input Parameters

comm - communicator of tasks to abort
errorcode - error code to return to invoking environment


Terminates all MPI processes associated with the communicator comm; in most systems (all to date), terminates all processes.

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.
