SYNTAXC Syntax
#include <mpi.h>
int MPI_Get_processor_name(char *name, int *resultlen)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_GET_PROCESSOR_NAME(NAME, RESULTLEN, IERROR)
CHARACTER*(*) NAME
INTEGER RESULTLEN, IERROR
C++ Syntax
#include <mpi.h>
void Get_processor_name(char* name, int& resultlen)
OUTPUT PARAMETERS
name A unique specifier for the actual (as opposed to virtual)
node.
resultlen Length (in characters) of result returned in name.
IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine returns the name of the processor on which it was called
at the moment of the call. The name is a character string for maximum
flexibility. From this value it must be possible to identify a specific
piece of hardware. The argument name must represent storage that is at
least MPI_MAX_PROCESSOR_NAME characters long.
The number of characters actually written is returned in the output
argument, resultlen.
NOTES
The user must provide at least MPI_MAX_PROCESSOR_NAME space to write
the processor name; processor names can be this long. The user should
examine the output argument, resultlen, to determine the actual length
of the name.
ERRORS
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument. C++ func‐
tions do not return errors. If the default error handler is set to
MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI::Exception object.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with
MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
may be used to cause error values to be returned. Note that MPI does
not guarantee that an MPI program can continue past an error.
