What is COOL?
COOL - Compact OSADL Online Lectures: Open Source meets Industry
- COOL is an OSADL webinar series.
- COOL takes place regularly once a month and covers new and state-of-the-art topics on Open Source software in industry, either on legal or on technical aspects.
- COOL editions each consist of two lectures covering a special "Open Source meets industry" topic followed by a discussion round. The first "basic" lecture provides basic knowledge with regard to the respective topic and the second "advanced" lecture dives deeper into the topic and highlights special aspects. The discussion round gives all participants the possibility to ask questions and discuss with the respective speakers and the audience.
- COOL speakers are OSADL experts on the one hand and external specialists on the other hand who kindly agreed to share their expert knowledge on the respective topic.
- COOL is a virtual event. The lectures are held by live video streams. Speakers will be available for questions and discussion in a video conference which will take part subsequent to the live video streams.
- COOL in general is designed to provide support how to best and compliantly use Open Source software in industry.
COOL September 2022 edition
Real-time in a virtual system?! Comparing real-time capabilities of various types of Linux hypervisors and containers
Wednesday, September 21, 2022, 2pm to 4pm CEST
[Replacement event for the cancelled COOL April 2022 edition]
Agenda COOL September 2022 edition:
2:00pm to 2:45pm CEST: | Basic lecture: Technical concepts of Linux hypervisors and containers, Alexander Bähr, OSADL |
2:45pm to 3:30pm CEST: | Advanced lecture: Real-time for Linux hypervisors and containers, Jan Altenberg, OSADL |
3:30pm to 4:00pm CEST: | Discussion and possibility to ask questions |
Description COOL September 2022 edition:
About 20 years ago it was one of the most important challenges for using Linux in embedded systems to equip it with real-time capabilities. Although many people were convinced that it is impossible to retrospectively equip a general purpose operating system with real-time capabilities, many important steps towards this goal have been done up to now, and it is well conceivable that in the foreseeable future this work will be completed. However, having reached an important goal never stops engineers to envisage new and even more challenging goals. One of them is achieving real-time behavior not only of the host system but even of Linux systems in hypervisors or containers. Since there is a wide variety of such systems available for Linux the question arises which of them, if any, is capable of running applications in guest systems with real-time response behavior.
Before answering this question, in the basic lecture of this COOL session Alexander Bähr of OSADL will give an overview of the various technical concepts of how hypervisors and containers work under Linux. Specifically, he will elaborate partitioning and separation strategies of these systems with respect to reaching real-time capabilities. In the advanced lecture Jan Altenberg of OSADL will show how hypervisors and containers may be configured to optimize real-time capabilities of guest systems. Not all of them successfully reached this goal, but at least one of them fulfilled the expectation that a real-time guest system could be created.
Recommended audience COOL September 2022 edition:
Software developers and engineers, hardware developers and engineers, system integrators, field application engineers, etc.
About the speakers of the COOL September 2022 edition:
- Alexander Bähr: Alexander Bähr is a state certified technician with a focus on control engineering. Since his youth Alexander has been enthusiastic about electronics and data processing, especially Linux and Open Source. During his further professional activity with the main focus on measurement technology and its data processing, he has successfully used the various options of Open Source software in his professional environment for many years. Since 2020 Alexander works as a technical computer scientist at the Open Source Automation Development Lab (OSADL) eG.
- Jan Altenberg: Jan Altenberg has more than 15 years of experience in developing and maintaining Embedded Linux systems. Jan studied information technologies at the University of Cooperative Education in Stuttgart (Germany). From 2002 - 2006 he was involved in the OCEAN project, a European research project, which defined an open controller platform based on real-time Linux and real-time CORBA. From 2007 to 2019 he worked for Linutronix as a Consultant, Trainer and Head of Technical sales. From April 2019 to 2021 he worked as Open-Source Technology Expert and Open-Source Compliance Officer for Continental Automotive GmbH. Since October 2021 Jan works as Senior Open Source Consultant and Embedded Systems Integrator at the Open Source Automation Development Lab (OSADL) eG. Jan is a frequent speaker on several conferences. In 2014, 2018 and 2019 he has been awarded with the "best speaker award" at the Embedded Software Engineering Congress in Sindelfingen (Germany).
