FAI (fully automatic installation) is a non-interactive system to install a Debian GNU/Linux operating system on a group of PCs or a Linux cluster. After installation, the systems are fully configured and ready to run. It is a scalable method for performing unattended installation and updating. Changes to the configuration files of the operating system are made by cfengine, shell, and Perl scripts.
Instant-Grid is a Knoppix-based live-CD bundled with a pre-configured grid environment based on the Globus Toolkit. One PC started from this CD becomes the Instant-Grid frontend. It also functions as a PXE boot-server, allowing other PCs in the same local network to boot the Instant-Grid environment. Together with the frontend, these PCs automatically form a working test grid. Like with the original Knoppix, the existing configuration of the participating PC is not touched (except maybe for enabling the PXE boot-option), and remains instantly available by a simple reboot.
Rocks is a complete "cluster on a CD" solution for x86 and IA64 Red Hat Linux COTS clusters. Building a Rocks cluster does not require any experience in clustering, yet a cluster architect will find a flexible and programmatic way to redesign the entire software stack just below the surface (appropriately hidden from the majority of users). Although Rocks includes the tools expected from any clustering software stack (PBS, Maui, GM support, Ganglia, etc), it is unique in its simplicity of installation.
Omnitty is a curses-based program that allows you to log into several machines simultaneously and interact with them, selectively directing input to individual machines or groups of selected machines. You can run both line-oriented and screen-oriented in the target machines, because it has built- in terminal emulation capability. When the window is large enough, Omnitty also displays a "summary area" for each machine, in which it shows what the latest output from the machine was, so you can have an idea of what is going on in each machine.
OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
