Re: is mandatory that master instance is the same kind of instance than compute nodes?

If the master is set to not be an exec node, the worker nodes can be a different type. The situation you describe, (small master instance, large compute instances) is my current set up.
I believe things are different when the master is set as an exec host.

Subject: [StarCluster] is mandatory that master instance is the same kind of instance than compute nodes?
I have been doing some testing with starcluster and I see that by default every machine is the same type of instance and that the sge_master is also an sge_exec node.
I have read in the documentation that the sge plugin allows to configure the master node to not being an exec node.
The ideal setup for me would be to have the master node being a small instance just running the sge_master and not running jobs and the compute nodes being bigger instances in terms of hardware resources.
is this setup currently possible in starcluster? or is mandatory that every machine is the same kind of instance?
thanks for your help.
