  MPI_Get_processor_name - Gets the name of the processor

  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'.
