| 28 papers on real-time and embedded Linux |
(Nov. 20, 2007)
 LinuxDevices.com is pleased to publish an overview and papers from the Ninth Real-Time Linux Workshop held in Linz, Austria, Nov. 2-3, 2007. The papers, available for free download without registration, span a broad range of topics, ranging from fundamental real-time technologies to applications, hardware, and tools.
As usual, the conference was organized by the Real-Time Linux Foundation. This year, it was held at the Johannes Kepler University (JKU) in Linz, Austria.

Conference Overview by Peter Wurmsdobler and Nicholas McGuire
Organizers Peter Wurmsdobler and Nicholas ("Der Herr Hofrat") McGuire wrote of this year's event, in part...
The 9th Real Time Linux Workshop was organized by the Real Time Linux Foundation, Inc. and by Institute for Measurement Technology Professor Zagar. It was supported by CELinux, IBM, and OSADL, and covered the current status of real-time in GNU/Linux systems, including safety aspects and automation issues.
The co-located ELC-E (Embedded Linux Conference Europa) covered current developments in the field of consumer electronics, with a clear focus on embedded. This ended up being a quite consistent mix, as many of the embedded systems need real-time capabilities, and many of the real-time developments are targeting embedded devices.
I would like to start this article with an apology to the seven participants from Kenya, D.R. Congo, and Nigeria that were declined a visa by Austrian authorities. This was a disturbing development, and should be a wake-up call to the free-software community. If we fail to keep our minds open, and if xenophobic fears prevent the free exchange of ideas, then it is up to us to correct such developments by not silently accepting them. In response to this, the Real Time Linux Foundation plans to hold RTLWS11 (2009) in Afrika, and we hope that the free-software community as well as commercial open-source users will support this effort.
Now to the pleasant part.
Opening with a keynote by Tim Bird on Consumer Electronics Linux Forum (CE Linux Forum), this workshop covered real-time and embedded in four tracks as well as in a showroom where a surprising amount of automation-related exhibitions were available.
The second day opened with a key-note by Peter Hofstee on the CELL broad band architecture (CELL BE). Mr. Dofstee detailed a fascinating architecture, that is much too interesting to only be used in game consoles.
The second day of presentations concluded with a panel discussion about "The Ideal GNU/Linux Distribution." The panel included representatives from Debian, MontaVista, WindRiver, TimeSys, Thales, and LinuTronix, and concluded that the ideal GNU/Linux has not yet been sighted.
Presentations at RTLWS9 are published as papers, although unfortunately some authors "forgot" to submit their final papers. So for those that had no opportunity to attend, LinuxDevices is providing the space to publish all papers for the general audience - so thanks to LinuxDevices.com for offering the Real Time Linux Foundation this opportunity!
ELC-E is a bit less formal, and did not have a paper requirement. However, many presentations from that event are available online, here.
In the context of RTLWS9/ELC-E, the OSADL working group Safety Critical Linux was launched with a kickoff meeting together with key industrial players. OSADL together with representatives of Siemens, Thales, IBM, Wago as well as the Technical University of Vienna, Institute of Computer Technology (ICT) and Lanzhou University, Distributed and Embedded Systems Lab (DSLab), set the initial road-map for the working group to deliver its final proposal by February 2008. This working group was formed to coordinate the growing interest of industry to utilize the vast resources of free-software/open-source in safety related systems.
We would like to thank those that supported RTLWS9, notably:- Prof. Bernhard Zagar and Renate Wolfmayr from the University of Linz
- Harald Hatzenbichler and Roland Poenitz from IBM for their support both financially as well as with a really cool key-note
- Tim Bird and Ruud Derwig from CE Linux Forum for organizing the embedded tracks as well as providing travel assistance for a number of speakers
- Carsten Emde, OSADL for their sponsoring support
Further we would like to announce that RTLWS10, Nov 2008 will be held in Mexico at the University of Guadalajara. Details to follow here.
