.TH MPI_Abort 3 "1/6/1997" " " "MPI"
.SH NAME
MPI_Abort \-  Terminates MPI execution environment 
.SH SYNOPSIS
.nf
#include "mpi.h"
int MPI_Abort( comm, errorcode )
MPI_Comm         comm;
int              errorcode;
.fi
.SH INPUT PARAMETERS
.PD 0
.TP
.B comm 
- communicator of tasks to abort 
.PD 1
.PD 0
.TP
.B errorcode 
- error code to return to invoking environment 
.PD 1

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

.SH NOTES FOR FORTRAN
All MPI routines in Fortran (except for 
.I MPI_WTIME
and 
.I MPI_WTICK
) have
an additional argument 
.I ierr
at the end of the argument list.  
.I 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
.I call
statement.

All MPI objects (e.g., 
.I MPI_Datatype
, 
.I MPI_Comm
) are of type 
.I INTEGER
in Fortran.
