[StarCluster] exclude the master node

[Ed Morris]

Jean-Pierre.

This option is a setting in the configuration file for star cluster.

Use the SGE plugin instead of the automatic queue setup.

[plugin sge]
setup_class = starcluster.plugins.sge.SGEPlugin
master_is_exec_host = False


Following argument excludes master as execution host.

Be sure to set the queue command to false before executing the SGE plugin.

Something like:

[cluster smallcluster]
disable_queue = True
plugins = sge


Hope this helps.

Ed
