NAME

MPI_ERRORS_RETURN - Error handler that just returns

SYNOPSIS

#include <mpi.h> 
void MPI_ERRORS_ARE_FATAL(MPI_Comm comm , int *err , ...); 

INPUT PARAMETERS

comm - intracommunicator (handle)

err - error code (integer)

DESCRIPTION

The MPI_ERRORS_RETURN() function is an error handler that returns control to user code. The error code err will then be the return value of whatever MPI function is failing. Most errors are recoverable in this MPI implementation. Only MPI_ERR_INTERN and MPI_ERR_OTHER may not be recoverable. The typical situation where this occurs is when the machine is critically out of memory, and cannot allocate the small message envelopes used for communication.

The communicator, comm is ignored.

There is no 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.
