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.
