Systems Project

The ARCS National Grid is interconnected using 'Gateways' operated at each ARCS member site. These gateways help provide a common interface to HPC facilities and data resources.

The Gateways use Xen to provide virtual machines.
Generally the host and virtual machines run CentOS. However there are exceptions.
A number of different Grid Software Stacks can be provided, each on their own virtual machine. For example: Globus 2.4 (Pre-WS), Globus 4, gLite
A number of specific functions are also provided, again, each on its own virtual machine. For example, a Data Staging machine and a Tomcat enabled portal machine.

Alternative Path to Upgrade VMs

At the moment, the official upgrade path is to stop the service, then go through the install procedure described in the how to install section.

The alternative is to install another VM, eg: ng2dev, test it, then change the hostname related settings. It will end up with less down time for production systems.
