User Guide
From UniCluster-UC5
Introduction
This User Guide provides an overview of the steps necessary for logging on to the cluster and using SGE to submit and monitor jobs. It also demonstrates other means of monitoring the cluster.
How to Logon to the Cluster
Note: By default, UniCluster 5 uses standard /etc/passwd for user accounts. Your system administrator may have changed that. If so, contact your administrator for details.
The controlling point of the cluster is the installer node. Any account that you maintain on that machine is synchronized to all of the compute nodes in the cluster. You should be able to use secure shell (SSH) to connect to any of the nodes.
Home Directories
The directories in /home are NFS-mounted from the installer node by default. Therefore, any files that you create in your home directory will automatically appear on all other nodes.

How to View the Status of a Cluster
Ganglia
To view the status of a cluster with Ganglia, the Ganglia kit must be installed and deployed within the cluster (see the Administrator Guide for details on deploying kits). Once the kit has been deployed, point a web browser at the node with the gmetad component installed on it (likely, the installer node). For example, if the component is installed on localhost, the URL for Ganglia will be http://localhost/ganglia.
Also, if the gmetad component is installed on the installer node, there will be a link from the UniCluster homepage (http://localhost) on the installer node directly to the Ganglia web interface.
Cacti
To view the status of a cluster with Cacti, the Cacti kit must be installed and deployed within the cluster (see the Administrator Guide for details on deploying kits). Once the kit has been deployed, point a web browser at the node with the Cacti component installed on it (likely, the installer node). For example, if the component is installed on localhost, the URL for Cacti will be http://localhost/cacti. The default username for Cacti is admin and the default password is also admin, although your administrator may have changed these.
Also, if the Cacti component is installed on the installer node, there will be a link from the UniCluster homepage (http://localhost) on the installer node directly to the Cacti web interface.
