Cluster vs Super
Hi there.

I'm currently playing around with a small cluster of mini boards running Debian. Or Raspbian to be precise. Each node is given a datafile and renders animation frames. This is as much a cluster as it c be, I'm using one as a header, I've written some scripts and code to automate certain tasks, but every node is totally isolated save it's wifi connection to the same network.

So I'm wondering what os' there are around that could use all these nodes as one. 12x4 cores could be fun to play around with, and may possibly save time as a lot of duplicated file checking would be avoided.

If I can get this working I'm prepared to sink a bit of cash into the project and add a load more nodes. So, what do you think my options would be?

Many thanks.

scversions

scversions(1M)						  System Administration Commands					    scversions(1M)

NAME

       scversions - Sun Cluster version management

SYNOPSIS

       scversions [-c]

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       The  scversions	command  commits  the cluster to a new level of functionality after a rolling-upgrade to new Sun Cluster software. With no
       arguments, the scversions command prints a message indicating whether a commitment is needed.

OPERANDS

       The following operands are supported:

       -c	    Commit the set of nodes that are currently active members of the cluster to the highest possible level of functionality.

		    When you upgrade a node (either through upgrade to a new release of the product or by application of a patch) and boot it back
		    into  the  cluster, some of the internal protocols on that node might have to run at lower versions in order to cooperate cor-
		    rectly with other nodes in the cluster.  When the cluster is in this state, some administrative actions might be disabled  and
		    some new functionality introduced in the upgrade might be unavailable.

		    When  you  run  this  command once from any node after all nodes are upgraded, the cluster switches to the highest versions of
		    internal protocols possible. Assuming that all nodes have the same Sun Cluster software installed at that time, all new  func-
		    tionality becomes available and any administrative restrictions are removed.

		    If	a  node that has not been upgraded is an active member of the cluster at the time you run the -c option to scversions, the
		    command has no effect because the cluster is already running at the highest possible level of functionality.

		    If a node has not been upgraded and is not an active member of the cluster when you run the -c option to scversions (for exam-
		    ple,  if  that  node is down for maintenance), the internal protocols of the cluster are upgraded to the highest possible ver-
		    sions.  You might have to upgrade the node that was not an active member of the cluster to enable it to rejoin the cluster.
