1. Oct. 15, 2009RePP Reconciling Predictability with Performance - the questions we asked - Reinhard Wilhelm Saarland University

2. Oct. 15, 2009RePP Questions - Notions Which concepts and metrics do you see for characterizing predictability? –(local) determinism, repeatability  PRET –analyzability  PREDATOR

3. Oct. 15, 2009RePP Questions - Strategies Are predictable systems only for a decreasing niche market? –amazing development since the workshop Thiele/Wilhelm: Design of Systems with Predictable Behaviour, 2003 and the follow-up publication Thiele/Wilhelm: Design for Timing Predictability. Real- Time Systems 28(2-3), 2004 Should one also follow mainstream software development?

4. Oct. 15, 2009RePP Questions - Architecture Will there be special hardware available in the future? How can embedded multi-core processors be designed in a time-predictable fashion? We probably meant How can time predictable embedded multi- core processors be designed? –several contributions in this workshop

5. Oct. 15, 2009RePP Questions – Resource Abstraction Computer science has been successful in removing resource interactions from interfaces. Does it make sense to enrich interfaces with resource-related information? –Several contributions at this EMSOFT If yes, on which level of abstraction (instruction set, software components,...)? Are there examples, where resource interactions (interferences on shared resources?) have an influence across abstraction layers? In particular, where do improvements on one layer lead to degradation on another?

6. Oct. 15, 2009RePP Questions - Applications Where are the applications where one needs to guarantee deadlines AND the average performance is of interest? How to parallelize embedded control algorithms and achieve time predictability? How to execute mixed real-time and non- real-time applications on an embedded multi- core in a predictable way?

7. Oct. 15, 2009RePP Goals of the workshop What we want answers to these questions your half-baked ideas, your unbred eggs what we do not want your results from the last 3 papers

8. Oct. 15, 2009RePP Proceedings will be published online may include your slides (in pdf) JJ will ask for final versions Current versions to be found at http://www.tik.ee.ethz.ch/~jchen/repp http://www
