Software Map

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.

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.

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.

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.

Son of Grid Engine is a highly-scalable and versatile distributed resource manager for scheduling batch or interactive jobs on clusters or desktop farms. It is a community project to continue Sun's Grid Engine. It is competitive against proprietary systems and provides better scheduling features and scalability than other free DRMs like Torque, SLURM, Condor, and Lava.

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.

Crossroads is a daemon running in user space, and features extensive configurability, polling of back ends using wake up calls, status reporting, many algorithms to select the "right" back end for a request (and user-defined algorithms for very special cases), and much more. Crossroads is service-independent: it is usable for any TCP service, such as HTTP(S), SSH, SMTP, RDP, and database connections. In the case of HTTP balancing, Crossroads can provide session stickiness for back end processes that need sessions, but aren't session-aware of other back ends. Crossroads can be run as a stand-alone daemon or via inetd, and features a management Web interface for monitoring and for modification of parameters.

redWall is a bootable CD-ROM firewall which focuses on Web-based reporting of the firewall's status. It includes Snort, snortsam, dansguardian, and support for fwbuilder, squidguard, reporting (using BASE/sarg/ntop/webfwlog), VPN (Openswan/PoPToP/Openvpn), Spam Filtering (spamassassin, dcc, razor2, clamav, amavis-new, dspam and maia mailguard), and mail-based, alerting. Configuration data are stored on a floppy or USB disk.

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.

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.
