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_PROCESSOR_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
       trailing    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 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
       communicators),    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
       predefined  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.
