23rd International Conference on Real-Time Networks and Systems

Lille, France, 4-6th November 2015

RTNS is a friendly conference with a great sense of community that presents excellent opportunities for collaboration.

The purpose of the conference is to share ideas, experiences and informations among academic researchers, developers and service providers in the field of real-time systems and networks.

RTNS 2015 will be in Lille, France.

RTNS 2015 is the 23rd edition of the conference formerly known as RTS (Real-Time Systems, Paris). The first 12 editions of RTS were french-speaking events held in Paris in conjunction with the RTS Embedded System exhibition. Since its 13th edition, the conference language of RTNS has been english.

Keynote Talk

Network-on-Chip Platforms for Real-Time Mixed-Criticality Application (download here)

Dr Leandro Soares Indrusiak Leandro Soares Indrusiak(Department of Computer Science, University of York)

Abstract

Network-on-Chip (NoC) is a widely used on-chip interconnect architecture for large multi and many-core processors. NoCs provide packet-switching infrastructure for multiple types of system-wide communications, such as message passing between tasks running on different cores, data transfers between external memories and local scratchpads, or paging and coherency mechanisms for multi-level caches. In all cases, the performance of the NoC affects system timeliness and thus must be taken into account when analysing application-level real-time guarantees. This is specially true when application tasks and communication packets of different levels of criticality share the NoC infrastructure. This talk will introduce and motivate a communication-centric design approach to multi and manycore systems, followed by the basics of Networks-on-Chip architectures, with special emphasis to the use of priority-preemptive virtual channels. Then, it will review the state-of-the-art in schedulability analysis for those NoC architectures, enabling safe upper bounds to end-to-end latency (tasks and packet flows) in single and mixed-criticality applications. Finally, it gives an insight on how schedulability analysis can be used as a fitness function in the design space exploration of NoC-based embedded systems, aiming to meet performance guarantees and optimise energy dissipation.

Biography

Leandro Soares Indrusiak graduated in Electrical Engineering from the Federal University of Santa Maria (UFSM, Brazil) and obtained a MSc in Computer Science from the Federal University of Rio Grande do Sul (UFRGS, Brazil) in 1995 and 1998, respectively. He held a tenured assistant professorship at the Informatics department of the Catholic University of Rio Grande do Sul (Brazil) from 1998 to 2000. From 2001 to 2008 he worked as a researcher at the Technische Universitaet Darmstadt (Germany) where he did his PhD and then lead a research group on System-on-Chip design. His binational doctoral degree was jointly awarded by UFRGS and TU Darmstadt in 2003. Since 2008, he is a permanent faculty member of University of York's Computer Science department (Lecturer 2008, Senior Lecturer 2013), and a member of the Real-Time Systems (RTS) research group. His current research interests include on-chip multiprocessor systems, distributed embedded systems, mapping and scheduling of applications over multiprocessor and distributed platforms, adaptive and reconfigurable computing, having published more than 100 peer-reviewed papers in the main international conferences and journals covering those topics. He currently supervises five PhD students and four post-doc research assistants. He is the principal investigator and technical leader of the EU-funded DreamCloud project (Dynamic Resource Allocation in Embedded and High-Performance Computing), and a co-investigator in the EPSRC-funded MCC project (Mixed Criticality Embedded Systems on Many-Core Platforms). He also coordinates two MSc programmes, serves as the department's Internationalisation Advisor, is a member of the EPSRC College, and a senior member of the IEEE.
