MPI_Get_processor_name(3OpenMPI)                                            MPI_Get_processor_name(3OpenMPI)



NAME
       MPI_Get_processor_name  - Gets the name of the processor.


SYNTAX
C 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_PROCES-SOR_NAME MPI_MAX_PROCESSOR_NAME
       SOR_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++ functions 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.
