Before a calculation can be performed on a parallel computer, it must first be decomposed into tasks which are assigned to different processors. Efficient use of the machine requires that each processor have about the same amount of work to do and that the quantity of interprocessor communication is kept small. Finding an optimal decomposition is provably hard, but due to its practical importance, a great deal of effort has been devoted to developing heuristics for this problem. The decomposition problem can be addressed in terms of graph partitioning. Chaco implements a variety of algorithms for graph partitioning and is used at most of the major parallel computing centers around the world to simplify the development of parallel applications, and to ensure that high performance is obtained. Chaco has contributed to a wide variety of computational studies including investigation of the molecular structure of liquid crystals, evaluating the design of a chemical vapor deposition reactor and modeling automobile collisions. Note: this port includes a patch provided by Walter Landry for use within MBDyn.

"twander" is a Filesystem Browser which runs on both Unix-like systems as well as Win32 systems. It embraces the best ideas of both similar GUI-driven programs (Konqueror, Windows Explorer) as well as text-based interfaces (Midnight Commander, List, Sweep). While the "twander" interface is graphical, all the major navigation, selection, and execution commands can be entered from the keyboard, not just the mouse. This means Power Users who are strong typists can minimize dependency on the mouse and materially speed up their interactions with the system. Moreover, unlike the other programs, "twander" does not have a built-in set of commands (which typically cannot be changed). Instead, "twander" supports a rich macro configuration language for virtually limitless user-definition of commands. The configuration language provides a simple mechanism for communicating the list of items currently selected in the GUI to the user-defined commands. Each user is thus free to configure a command set unique and appropriate to their needs. As with the navigation commands, user-defined commands can be invoked with either the keyboard (a single keystroke) or the mouse (a menu selection).

Word8 library to be used with Data.ByteString.

This module can be used to parse directory listings.

jMusic is a project designed to provide composers and software developers with a library of compositional and audio processing tools. It provides a solid framework for computer-assisted composition in Java, and is also used for generative music, instrument building, interactive performance, and music analysis. jMusic supports musicians with its familiar music data structure based upon note/sound events, and provides methods for organising, manipulating and analysing that musical data. jMusic scores can be rendered as MIDI or audio files for storage and later processing or playback in real-time. jMusic can read and write MIDI files, audio files, XML files, and its own .jm files; there is real-time support for JavaSound, QuickTime and MIDIShare. jMusic is designed to be extendible, encouraging you to build upon its functionality by programming in Java to create your own musical compositions, tools, and instruments. In a spirit of mutual collaboration, jMusic is provided free and is an open source project.

LPAC is a codec (coder / decoder) for lossless compression of digital audio files. "Lossless" means that any compressed file can be decompressed in a way it will be bit-wise identical with the original. This is the main advantage of LPAC compared to lossy formats like MP3, WMA or RealAudio. On the other hand, lossy codecs can achieve higher compression ratios. For example, MP3 at 128 kbit/s achieves a (fixed) compression ratio of 11, whereas LPAC's compression ratios range from 1.5 to 4, strongly depending on the audio material. Typically they are around 2 for pop music and 2.5 for classical music. This may not seem much, but remember you will get back every single bit, no matter how often you subsequently compress and decompress a file. It is true that general archivers (Zip, LZH, gzip) are lossless, too, but they often achieve nearly no compression on audio files.

WildMIDI is a simple software midi player which has a core softsynth library that can be used with other applications. The WildMIDI library uses Gravis Ultrasound patch files to convert MIDI files into audio which is them passed back to the calling application for further processing or output. The API of the library is designed so that it is easy to include WildMIDI into applications that wish to include MIDI file playback. With multiple MIDI file support you can develop applications to mix several midi files together at the same time and with the next release you will be able to use a different patch set for each MIDI file. The wildmidi player is a demonstration program to show the capabilities of libWildMidi.

GNU Data Access (GDA) is an attempt to provide uniform access to different kinds of data sources (databases, information servers, mail spools, etc). It is a complete architecture that provides all you need to access your data, defined by a set of CORBA interfaces as generic as possible (but very powerful at the same time) so that any kind of data source can be accessed through them. libgda is an interface to the GDA architecture, providing a nice wrapper around the CORBA interfaces, for both the client and the server parts. It also provides a bunch of tools to help you both in the development and management of your data sources, all done through the GDA model's set of CORBA interfaces. libgda was part of the GNOME-DB project, but has been separated from it to allow non-GNOME applications to be developed based on it.
