Following the meetings of academics, developers and users of real-time and embedded Linux at the previous 12 real-time Linux workshops held world-wide (Vienna, Orlando, Milano, Boston, Valencia, Singapore, Lille, Lanzhou, Linz, Guadalajara, Dresden and Nairobi), the Real-Time Linux Workshop for 2011 will come to the Czech Technical University in Prague, Faculty of Electrical Engineering, Dept. of Control Engineering - academic OSADL member since 2008. The workshop will be held from October 20 to 22.


Embedded and real-time Linux are gaining traction in consumer electronics and in industrial computing in breath-taking speed. Linux runs a wide range of industrial applications including real-time and safety-related systems. And the best is that everyone on earth has access to this unparalleled pool of Open Source software as long as he or she has access to the Internet. Nevertheless, this access is by no means one-way - the return paths are from providing bug reports, additions and ideas for enhancements and, finally, the very important mechanism of peer review that makes Linux, and particularly real-time Linux, as stable and innovative as it is.

In addition to sending patches and providing feedback via Internet, direct mutual exchange between field engineers, system integrators, and project managers, and hardware, driver, board support package and kernel developers is needed. The Real Time Linux Workshop is successfully serving this purpose since more than 10 years. We are looking forward to meeting each other at another great Real Time Linux Workshop - this time in Prague, Czech Republic.

Call for papers

Authors from academics, industry as well as the user community are invited to submit papers on original work related to Open Source real-time systems. Such work may deal with general topics related to Open Source based real-time systems but also with research, experiments and case studies, as well as with issues of integration of Open Source real-time and embedded systems. A special focus will be on industrial case studies and safety-related systems. Topics of interest include, but are not limited to:

  • Modifications and variants of the GNU/Linux operating systems extending its real-time capabilities
  • Contributions to real-time Linux variants, drivers and extensions
  • User-mode real-time concepts, implementation and experience
  • Real-time Linux applications, in academia, research and industry
  • Safety-related FLOSS systems
  • Work in progress reports, covering recent developments
  • Educational material on real-time Linux
  • Tools for embedding Linux or real-time Linux and embedded real-time Linux applications
  • RTOS core concepts, RT-safe synchronization mechanisms
  • RT-safe interaction of RT and non RT components
  • IPC mechanisms in RTOS
  • Analysis and benchmarking methods and results of real-time GNU/Linux variants
  • Real-time networking with COTS
  • Medical applications using COTS and FLOSS
  • Debugging techniques and tools, both for code and temporal debugging of core RTOS components, drivers and real-time applications
  • Real-time related extensions to development environments

Abstract submission

If you wish to present a paper at the workshop, please submit an abstract using the submission page at

Hints for the composition of the abstract

The purpose of the abstract is to provide reviewers with as much information as possible to estimate the relevance and the importance of the work. Although it is well conceivable that some part of the data are not yet available at the time of submission, enough information must be provided to make the given conclusion comprehensible.

In detail, we need i) a statement about the rationale of the research, ii) a description of how experiments, studies, observations etc. were carried out, iii) a summary of the results, and iv) a conclusion to what extent the results will change our current views - or at least have the potential to do so.

In consequence, sentences starting with "This paper will ...", "We want to find out ...", "We will write software that ...", "The results may show ..." etc. probably are not able to fulfill the above mentioned prerequisites for an acceptable abstract.

With the exception that we have not, at least not yet, defined an upper limit of the word count, Philip Koopman's "How to write an abstract" quite well describes our expectation.

Final paper to be included into the RTLWS13 Proceedings

Upon acceptance of an abstract by the RTLWS13 Program Committee, the author will be invited to submit a full paper in a form defined by A detailed description of the editing and formatting process will be provided along with the notification email.

About the Czech Technical University

The Czech Technical University (CTU) in Prague is one of the largest technical universities in the Czech Republic and the oldest institute of technology in Central Europe - it was established in 1707. The university is organized into seven faculties and currently has about 23,000 students in total with approximately 2,300 students graduating each year. At the Faculty of Electrical Engineering, Zdeněk Hanzálek has been building up a group since 2005 that is focusing on Industrial Informatics including the notorious scheduling problems, issues of combinatorial optimization algorithms as well as the more general topic of real-time control systems. Much of this work has been heavily based on Open Source, and particularly the real-time variants of GNU/Linux have been a long-time companion. This is visible in numerous national and international projects some of which are prominent projects with Open Source focus in the context of the Sixth and Seventh Framework Program (FP6/FP7) as for example OCERA (Open Components for Embedded Real-time Applications) and FRESCOR (Framework for Real-time Embedded Systems based on COntRacts). These projects are extending the capabilities of real-time enhanced Linux as well as integrating communication capabilities and distributed system concepts into Open Source implementations.

About the local organizers

Michal Sojka

Michal Sojka got his PhD at the Czech Technical University in Prague, Faculty of Electrical Engineering, and has been a long-time contributor to Open Source projects focused on enhancing and extending real-time capabilities of GNU/Linux. While the research on industrial communications and embedded systems is quite widely entrenched in the Open Source community, the issues of design and verification of real-time systems has not been getting the necessary attention from the broad FLOSS real-time community. Aside from research and development promoting Open Source also means spreading the enthusiasm along with the bleeding edge technology - this is well documented in a number of, sometimes a bit strange, robots that he has been building with his students. As the real-time Linux workshop heavily builds on a strong local organizer, having won not only the Czech Technical University to host this annual event but powerful Open Source supporters like Michal Sojka for the local organization committee is the first important step to making this event a success.

Pavel Píša

Pavel Píša who finalized his PhD recently, is a devoted Open Source advocate not only supporting technical efforts with his outstanding work in the area of field bus support for Linux (i.e. the work on Linux/RT-Linux CAN driver) but also his continuous work on more general embedded Linux issues, providing patches for a number of different architectures, file systems, device driver fixes and of course control and communication specific Linux drivers. This work is also visible in a number of publications and his participation at a number of previous Real Time Linux Workshops. The Real Time Linux Foundation working group of OSADL is happy to have won him as one of our local organizers for the upcoming Real Time Linux Workshop at CTU.

Petr Hodač

Petr Hodač is the main coordinator of the Prague InstallFest since longtime. This meeting of GNU/Linux enthusiasts, inaugurated in 1999, is organized by students at the Silicon Hill Club and UN*X Technologies Center. It is open not only to students of the Czech Technical University but to everybody. Originally intended as a peer-to-peer help group to install GNU/Linux systems on desktop computers, it is now a workshop and conference with a strong focus on using, maintaining and programming Open Source technologies and has gained an excellent reputation in the Czech GNU/Linux community. The organizers are very glad that Petr accepted to join the local organization committee.
