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 syncroniza-
     tion 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.	 De-
	  faults 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.
