MPI_Get_processor_name(3)          Open MPI          MPI_Get_processor_name(3)



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_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++
       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.
