MPI_Get_processor_name(3)	      MPI	     MPI_Get_processor_name(3)

NAME
       MPI_Get_processor_name -	 Gets the name of the processor

SYNOPSIS
       int MPI_Get_processor_name( char	*name, int *resultlen )

OUTPUT PARAMETERS
       name   -	 A  unique  specifier  for  the	actual (as opposed to virtual)
	      node. This must be an array of  size  at	least  MPI_MAX_PROCES-
	      SOR_NAME .

       resultlen
	      -	Length (in characters) of the name

NOTES
       The  name  returned should identify a particular	piece of hardware; the
       exact format is implementation defined.	This name may or  may  not  be
       the same	as might be returned by	gethostname , uname , or sysinfo .

THREAD AND INTERRUPT SAFETY
       This  routine  is  thread-safe.	 This  means  that this	routine	may be
       safely used by multiple threads without the need	for any	 user-provided
       thread  locks.  However,	the routine is not interrupt safe.  Typically,
       this is due to the use of memory	allocation routines such as malloc  or
       other  non-MPICH	 runtime  routines  that are themselves	not interrupt-
       safe.

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

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

       In  Fortran,  the  character argument should be declared	as a character
       string of MPI_MAX_PROCESSOR_NAME	rather	than  an  array	 of  dimension
       MPI_MAX_PROCESSOR_NAME .	 That is,
       character*(MPI_MAX_PROCESSOR_NAME) name

       rather than
       character name(MPI_MAX_PROCESSOR_NAME)

       The two

       The sizes of MPI	strings	in Fortran are one less	than the sizes of that
       string in C/C++ because the C/C++ versions provide room for the	trail-
       ing    null    character	   required    by    C/C++.	For   example,
       MPI_MAX_ERROR_STRING is mpif.h is one smaller than the  same  value  in
       mpi.h .	See the	MPI-2 standard,	sections 2.6.2 and 4.12.9.

ERRORS
       All  MPI	 routines  (except  MPI_Wtime  and MPI_Wtick ) return an error
       value; C	routines as the	value of the function and Fortran routines  in
       the last	argument.  Before the value is returned, the current MPI error
       handler is called.  By default, this error handler aborts the MPI  job.
       The error handler may be	changed	with MPI_Comm_set_errhandler (for com-
       municators),	MPI_File_set_errhandler	    (for      files),	   and
       MPI_Win_set_errhandler	(for   RMA   windows).	  The	MPI-1  routine
       MPI_Errhandler_set may be used but its use is deprecated.   The	prede-
       fined error handler MPI_ERRORS_RETURN may be used to cause error	values
       to be returned.	Note that MPI does not guarentee that an  MPI  program
       can  continue  past an error; however, MPI implementations will attempt
       to continue whenever possible.

       MPI_SUCCESS
	      -	No error; MPI routine completed	successfully.
