Hi, all
StarCluster (http://web.mit.edu/stardev/cluster/) is a very nice tool to launch a grid engine cluster. Unfortunately, it does not support Eucalyptus nicely. Moreover, customization is not easy to support. I developed a tool that solved these two issues. This tool will execute a set of scripts you write in an orderly manner to a number of the hosts in cluster. By this way, you configure the cluster by preparing scripts. The advantage over other highly integrated tool is flexibility. You can configure local cluster, EC2 cluster, or Eucalyptus cluster. You can write script in language you are comfortable with.
