nfs-utils provides the required support programs for using the Linux kernel's NFS support, either as a client or as a server (or as both).

Lustre is a novel storage and filesystem architecture and implementation suitable for very large clusters. It is a next-generation cluster filesystem that is currently running on clusters that have tens of thousands of nodes, petabytes of storage, and move hundreds of GB/sec.

LAM/MPI is an implementation of the Message Passing Interface (MPI) parallel standard that is especially friendly to clusters. It includes a persistent runtime environment for parallel programs, support for all of MPI-1, and a good chunk of MPI-2, such as all of the dynamic functions, one-way communication, C++ bindings, and MPI-IO.

OSCAR (Open Source Cluster Application Resources) is a snapshot of the best known methods for building, programming, and using clusters. It consists of a fully integrated and easy-to-install software bundle designed for high performance cluster computing.

MAC Changer is a GNU/Linux utility for viewing/manipulating the MAC addresses of network interfaces. It can set specific, random, vendor-based (with a 6600+ vendor list), and device-type-based MACs.

The ENBD (Enhanced Network Block Device) is an industrial-strength version of the Linux kernel NBD. It makes a remote disk look like a local block device, allowing cheap and safe realtime mirrors to be built over the net. It features internal block-journalling and multichannel failover.

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.

The Spread Toolkit provides tools for developing reliable and robust distributed applications ranging from collaboration tools to fault-tolerant database servers to replicated Web servers. It consists of a daemon which provides multicast messaging, reliability, ordering, and membership services, and a library which applications link with. Spread provides a simple API for writing group applications and is designed to provide high performance for local and wide area networking applications.

Drbd is a block device which is designed to build high-availability clusters. This is done by mirroring a whole block device via a (dedicated) network. You could see it as a network raid 1.

Linux makes a great platform for deploying diskless workstations that boot from a network server. The LTSP is an open source project to create the administration tools that will make setting up a diskless Linux workstation easier.

The GCC UPC toolset provides a compilation and execution environment for programs written in the UPC (Unified Parallel C) language. The GCC UPC compiler extends the capabilities of the GNU GCC compiler. The GCC UPC compiler is implemented as a C Language dialect translator, in a fashion similar to the implementation of the GNU Objective C compiler.
