This section tells you how to get started using Sun Grid Engine (SGE). SGE is a distributed resource management software and it allows the resources within the cluster (cpu time,software, licenses etc) to be utilized effectively. Also, the SGE Roll sets up Sun Grid Engine such that NFS is not needed for it's operation. This provides a more scalable setup but it does mean that we will lose the high availability benefits that a SGE with NFS setup offers. Another thing that the Roll does is that that generic queues are setup automatically the moment new nodes are being integrated within the Rocks cluster and booted up.
