xml2hostconf generates RPM packages, dhcpd.conf, pxelinux files, kickstart files, and HTML documentation with XSLT. It is a framework for central configuration and automatic installation of a Fedora/Redhat Linux network. Configuration files get shipped to the client computers by generated RPMs.
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.
DJFractal is yet another fractal generator which distributes fractal data to multiple computers. Fractal data are created locally and distributed to other computers that run the appropriate fractal-generation software, which may be hosted on workstations, or on a Java enabled Web-browser through applets, or on a system with JavaCard. DJFractal's unique feature is the "smart" algorithm it uses to compute (and draw) the most interesting part of a fractal first.
Mandala is a Java library which eases the development of concurrent object-oriented applications by using the concept of asynchronous references. Mandala also provides remote asynchronous references in order to create distributed applications. Mandala is dynamic in that objects do not have to be specifically written to be accessed asynchronously (and remotely).
BitTorrent Queue Manager is a console-based BitTorrent client running on top of BitTornado that provides built-in queue management functions. It also provides a remote interface compatible with ABC for Web-based control. Furthermore, peer information can be queried, including country and network names, and a built-in crawler can gather new torrents on specified trackers or catalog sites for downloading automatically.
ProActive is a Java library for parallel, distributed, and concurrent computing as well as mobility and security in a uniform framework. It provides a comprehensive API and a graphical interface and is based on an Active Object pattern, a uniform way to encapsulate a remotely accessible object, a thread as an asynchronous activity, an actor with its own script, a server of incoming requests, a mobile and secure agent, and a component with server and client interfaces. It simplifies the programming of applications distributed over a LAN, clusters, an intranet, or Internet GRIDs.
Linda is a widely studied distributed computing environment, centered around the notion of a tuple space. A tuple space is a bag (also called a multi-set) of tuples. A tuple is an ordered, typed chunk of data. Tuple spaces exist independently of processes in the system, and the data placed into a tuple space also exist independently. PyLinda is a simple implementation of a Linda system, but it also includes several of the more recently proposed extensions to Linda in the form of multiple tuple spaces, garbage collection, sane non-blocking primitives and bulk tuple operations.
JCGrid is a set of easy-to-use tools for real-world grid-computing. It doesn't require any file system sharing capability (such as NFS). It allows you to easily split a CPU-intensive task among several computers by using the JCGrid framework. Any file required for completing the task will be transferred by the framework. A cache is used in order to minimize file transfers. You can easily add or remove computers from the grid at runtime without losing any work. Support for POVRay is included as an example of use.
