MPI_GET_PROCESSOR_NAME, MPI_Get_processor_name

Purpose

Returns the name of the local processor.

C synopsis

#include <mpi.h>
int MPI_Get_processor_name(char *name,int *resultlen);

C++ synopsis

#include mpi.h
void MPI::Get_processor_name(char*& name, int& resultlen);

FORTRAN synopsis

include 'mpif.h' or use mpi
MPI_GET_PROCESSOR_NAME(CHARACTER NAME(*),INTEGER RESULTLEN,
      INTEGER IERROR)

Parameters

name
     is a unique specifier for the actual node (OUT)

resultlen
     specifies the printable character length of the result returned in
     name (OUT)

IERROR
     is the FORTRAN return code. It is always the last argument.

Description

This subroutine returns the name of the local processor at the time of the
call. The name is a character string from which it is possible to identify
a specific piece of hardware. name represents storage that is at least
MPI_MAX_PROCESSOR_NAME characters long and MPI_GET_PROCESSOR_NAME can write
up to this many characters in name.

The actual number of characters written is returned in resultlen. For C,
the returned name is a null-terminated string with the terminating byte not
counted in resultlen. For FORTRAN, the returned name is a blank-padded
string.

Errors

MPI not initialized
