Genoa Active Message MAchine is a low-latency, high-throughput driver wrapper for the Linux kernel, using Active Ports (a version of Active Messages).
Genoa Active Message MAchine runs parallel to the IP stack and is designed for LANs only.
Main features:
- A low latency, high throughput communication system for clusters of PCs
- Supports both single and dual CPU processing nodes (Intel IA-32 or x86_64)
- Runs on Gigabit Ethernet
- SPMD parallel processing with message passing
- Can run IP traffic when not in use
- Good programmability thanks to fairly high abstraction level
- Reliable thanks to mechanisms for retransmission of missing packets
- Implemented as a network device driver for Linux 2.6, and released under GNU GPL
Network Of Workstations (NOWs) and clusters of PCs interconnected by modern, industry-standard LAN fabrics (Gigabit Ethernet, Myrinet, SCI) and running the Linux operating system, have became an attractive and cost-effective architecture for parallel and distributed applications. The usual drawback of a standard PC cluster is the poor performance of the support to inter-process communication over the interconnect. Current implementations of industry-standard communication primitives, APIs, and protocols, usually show high communication latencies and low communication throughput.
We have developed a system for inter-process communication, called the Genoa Active Message MAchine (GAMMA). GAMMA runs on Linux clusters of PCs with Intel IA-32 processors (Intel Pentium, AMD K6, and superior models), or x86_64 processors (AMD Athlon64, AMD Opteron, Intel EMT-64), networked by a Gigabit Ethernet.
The core of GAMMA is a custom Linux network device driver, which operates the Network Interface Card (NIC). The GAMMA driver delivers low latency, high throughput communication services based on Active Ports, a mechanism derived from Active Messages. Both point-to-point and broadcast communications are provided. Broadcast communication exploits the Ethernet broadcast directly.
The GAMMA driver is able to manage standard IP traffic as long as no parallel job is running. Therefore, all IP services are up and running whenever the cluster is not in use by any parallel job.
The communication mechanisms implemented in the GAMMA driver are made available to application writers through the GAMMA user library. The GAMMA library provides support to application launch, process grouping, point-to-point/broadcast communications based on the Active Ports mechanisms, and some collective routines (barrier synchronization, and broadcast).
GAMMA provides two levels of QoS. The lower one, corresponding to the fastest communications, is a best-effort service. With this service, network congestion and ``hot spots may cause the receiver NIC or even the LAN switch to loose packets by overrun. The other QoS level provides flow-controlled communication, ensuring reliability up to hardware faults, at a negligible performance penalty.
Installing the GAMMA driver requires only two small and marginal patches to the original Linux kernel. The Linux kernel extended by the GAMMA driver must be installed on each PC in the cluster.
A porting of MPI atop GAMMA is available, called MPI/GAMMA.

Tk::Month is a calendar widget which shows one month at a time.

SYNOPSIS

use Tk;
use Tk::Month;

$m = $parent->Month(
-month => July,
-year => 1997,
-title => %b %y,
-command => &press,
-printformat => %e,
-navigation => [0|1],
-includeall => [0|1],
-showall => [0|1],
-first => [0|1|2|3|4|5|6],
)->pack();

$m->configure(
-month => July,
-year => 1997,
-command => &press,
-printformat => %e %B %Y %A,
-navigation => [0|1],
-includeall => [0|1],
-showall => [0|1],

Sman is the Searcher for Man pages. Based on the example of the same name in Josh Rabinowitzs article "How To Index Anything" in the July, 2003 issue of Linux Journal (http://www.linuxjournal.com/article.php?sid=6652), sman is an enhanced version of apropos and man -k. Sman project adds several key abilities over its predecessors:
- Supports complex natural language text searches such as "(linux and kernel) or (mach and microkernel)"
- Shows results in a ranked order, and optionally an extract (using -e) of the manpage showing the searched text highlighted
- Allows for searches by manpage section, title, body, or filename (use metaname=searchword)
- Indexes the complete contents of the man page, not just the title and description
- Uses a prebuilt index to perform fast searches
- Performs stemming so that a search for "searches" will match a document with the word "searching"

Klusters is a powerful and easy-to-use graphical application for spike sorting of extracellular neuronal recordings.
While the accuracy and speed of spike sorting is dramatically improved by automatic classification algorithms, the results of automatic algorithms must be examined manually to ensure that the assigned clusters correspond to single neurons. Klusters has been carefully designed to make this process as fast and error-free as possible.
Main features:
- Multiple type of views including Cluster View displaying spikes in the PCA feature space, Waveform View and Correlation View displaying auto-and cross-correlograms.
- Cluster colors making it easy to quickly identify a given cluster across different views.
- Time trajectory display to identify possible electrode drift.
- "Grouping Assistant" to suggest which pairs of clusters may result from overclustering of a single neuron.
- "Recluster" feature to automatically split clusters that may be several distinct neurons (underclustering), using an external classification program.
- Multiple displays open at once, which can be useful to examine different subsets of the data in parallel.
- Multiple undo and redo on the last actions.
- Print and export to postcript and pdf.
- Ergonomic user interface for maximum speed and reliability.
Enhancements:
- The source archive klusters-1.4.tar.gz released on July 08 did not compiled on certain distributions, this is now corrected.
- If you have encounter this problem, please download a copy of the corrected archive and try again. [This does not affect the debian package].
- In addition a layout bug was corrected in the documentation. [This affects both the source archive and the debian package].

Quantian distribution is a remastering of Knoppix, the self-configuring and directly bootable dvd/cdrom that turns any pc or laptop (provided it can boot from cdrom/dvd) into a full-featured Linux workstation.
Recent versions of Quantian are based on clusterKnoppix and add support for openMosix, including remote booting of light clients in an openMosix terminal server context. Earlier releases are still available; see below for URLs for downloads as well as ordering information.
Brief introductory information is available in a paper (from June 2004) submitted to The Political Methodologist, slides from the presentation at Usenix 2004 (July 2004), and in the earlier (revised) paper about Quantian that has appeared in the DSC 2003 Proceedings.
Quantian is an extension of Knoppix and clusterKnoppix from which it takes its base system of around two gigabytes of software, along with fully automatic hardware detection and configuration.
Enhancements:
- Kernel 2.6.12, KDE 3.5 / 3.4, OpenOffice 2.0, ... and more from Knoppix 4.0.2
- a backport of the openMosix-enabled 2.4.27 kernel and openMosix tools from the last clusterKnoppix release,
- very comprehensive support for GNU R with over 870 packages from CRAN and BioConductor, plus ESS, Ggobi, Rpad, RKward, RSPerl, JGR, ...
- addition of the Java 1.5.0 SDK enabling us to add ImageJ, Weka, JGR, Mondrian;
- plus a number of other new packages (inkscape, orsa, praat, wxmaxima, some more Debian documentation...)
- and still loads more of math, bio, engineering, LaTeX, ... software

Syllable was born in July 2002 as a fork of the AtheOS operating system. Several AtheOS developers, concerned about the long-term development of AtheOS, created Syllable to ensure that development would continue.
Syllables goal is to create a reliable and easy-to-use open source operating system for the home and small office user. We also want to encourage developers to create an operating system that is intuitive, easy to use, and powerful.
