Thank Eduardo for your advice, it resolves my problem but not
totally. I don't receive the error anymore, the host files and the
sgeadmin are created, but I still have not ssh connectivity between
nodes, logging to the master node I'm not able to ssh connect to
worker nodes from it.<br>
Thank you.<br>

I'm using starcluster to manage an MPI cluster for parallel
scientific computation. I don't want to use the pre-installed
OpenMPI environment since the executables ? have to use are
compiled with Intel softwares. So I have my private CentOS AMI
created from aws console with all the Intel environment
pre-installed. The problem is that IntelMPI uses by default
ssh connectivity without password authentication to make nodes
communicate amoung them to work. I want to know if there is
some feauture in the config starcluster file such that ssh
connectivity intra nodes comes pre setted with rsa
authentication. I have read that this feauture should be
enabled by default with the sgeadmin user, but when i launch
the cluster at a certain point I received this error: <br>
<br>
!! ERROR - Error occured while running plugin
'starcluster.clustersetup.DefaultClusterSetup': <br>

caused by <br>

directory being owned by root. To fix this you'll <br>

and neither the user sgeadmin is created neither the
/etc/hosts file is filled with the names and IPs of all nodes
of the cluster. </div>
