Thank you Ed, this is exactly what I was looking for.
Next time, I'll check out the config file first before asking.

Subject: Re: [StarCluster] exclude the master node
This option is a setting in the configuration file for star cluster.
Use the SGE plugin instead of the automatic queue setup.
setup_class = starcluster.plugins.sge.SGEPluginmaster_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.
[cluster smallcluster]disable_queue = Trueplugins = sge
Hope this helps.

usually I use a "cheap" master node when I'm running starcluster on spot instances.
And usually, I launch my jobs with that kind of command :
qsub -b y -cwd -pe orte 24 mpirun ./mpi-executable arg1 arg2
I was wondering, how could I exclude the master node from the list of nodes running the job. Since the master node is slower in my case, it clearly affects the efficiency of the computation.
