BARRIERD(1)                OpenBSD Reference Manual                BARRIERD(1)

NAME
     barrierd - syncronize a process on a number of machines.

SYNOPSIS
     barrierd [-v] [-p port]

DESCRIPTION
     The barrierd daemon runs on a host, and accepts barrier connections from
     the client program barrier.  It handles the connections and
     syncronization of various barriers being set up and taken down across the
     cluster.

     -v   Prints the version of ClusterIt to the stdout, and exits.

     -p   Specifies a port number for the barrierd daemon to listen on.
          Defaults to 1933, and overrides the BARRIER_PORT environment
          variable.

ENVIRONMENT
     barrierd utilizes the following environment variables:

     BARRIER_PORT  Sets the default remote port to connect to.

DIAGNOSTICS
     Exit status is 0 on success, 1 if an error occurs.

SEE ALSO
     barrier(1), dsh(1),

HISTORY
     The barrierd command appeared in clusterit 1.1.

AUTHOR
     Barrierd was written by Tim Rightnour.

BUGS
     Barrierd can only handle up to 10 unique barrier tokens at any one time.
     In addition, it can only handle a barrier size of up to 512 nodes.  These
     values can be modified by recompiling the program.
