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>
!!! ERROR - Cannot create user: (uid: 0, gid: 0). This is caused by
<br>
!!! ERROR - <i class="moz-txt-slash"><span class="moz-txt-tag">/</span>home<span class="moz-txt-tag">/</span></i> directory being owned by root.
To fix this you'll
<br>
!!! ERROR - need to create a new AMI. Note that the instance is
still
<br>
!!! ERROR - up.
<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.
