NAME

       MPI_Comm_set_info - Set communicator info hints

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Comm_set_info(MPI_Comm comm, MPI_Info info)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_COMM_SET_INFO(COMM, INFO, IERROR)
            INTEGER   COMM, INFO, IERROR

INPUT PARAMETERS

       comm      Communicator on which to set info hints

       info      Info object containing hints to be set on comm

OUTPUT PARAMETERS

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_COMM_SET_INFO  sets new values for the hints of the communicator associated with comm.
       MPI_COMM_SET_INFO is a collective routine. The  info  object  may  be  different  on  each
       process,  but  any  info  entries  that  an  implementation requires to be the same on all
       processes must appear with the same value in each process's info object.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran routines in the last argument.

       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.
