Nice to know. This leads to another question. If you mix c1 instances (for master) with cc instances (for nodes) you will probably be out of the 10 Gbps network since placement groups works only for cluster instances, right?<div>
So if you really need bandwidth you will have to provision all instances as cluster instances even though the master would not need to be that big.</div><div><br></div><div>Sergio<span></span><br><br>Em terça-feira, 15 de maio de 2012, Ron Chen escreveu:<br>

If you grep the source, you will find references to create_placement_group(), get_placement_group() and many placement group functions in the starcluster source code.<br>

Subject: [StarCluster] Placement groups<br>
<br>
<br>
Does StarCluster deploy the cc instances on a placement group to take advantage of a 10 Gbps network?<br>
<br>
