Nous organisons du 8 au 12 juin 2015 l’école thématique ARCHI’15 « Architecture des systèmes matériels et logiciels embarqués, et méthodes de conception associées ». Toutes les informations sur cette école sont sur son site : http://cristal.univ-lille.fr/archi15. Nous aurons plaisir à vous y rencontrer.
The 23rd edition of the RTNS conference will be held at Lille from 4th to 6th November 2015, and will be organized by Julien Forget of the Émeraude group. RTNS is an international conference on Real-time systems and communication networks.

Le 26 Mai 2015 à 10h – 11h, dans l’amphitheatre à IRCICA, Juri Lelli (ARM Ltd) présentera le séminaire:
What’s so fun about the Linux Scheduler? and why you might want to start playing this game
The last few years have seen a lot of activity on the Linux Kernel Mailing List around the Linux Scheduler. Among others, ARM Ltd. has developed solutions for efficient scheduling on heterogeneous (big.LITTLE) architectures; The RETIS Laboratory of the Scuola Superiore Sant’Anna (Pisa, Italy) has invested time in developing and pushing to mainline an implementation of a well known real-time scheduling algorithm for time sensitive applications. Since I was part of the latter research activity and I recently joined the former endeavour, in this talk I will give an overview of both research activities. I will also discuss possible applications with an eye towards open questions and research opportunities. For the keywords eager, I will talk about: SCHED_NORMAL (Completely Fair Scheduling, SCHED_DEADLINE (Constant Bandwidth Server), big.LITTLE systems and Energy Models, Global Task Switching (GTS/HMP), Energy Aware Scheduling (EAS), Dynamic Voltage and Frequency Scaling (DVFS)… and beers!
Juri Lelli received a Bachelor’s degree in Computer Engineering at the University of Pisa (Italy) in 2006, and a Master’s degree in Computer Engineering at the University of Pisa (Italy) in 2010 with a thesis titled “Design and development of real-time scheduling mechanisms for multiprocessor systems”. He then earned a PhD degree at the Scuola Superiore Sant’Anna of Pisa, Italy (ReTiS Lab). His PhD thesis focused on reducing the gap between classical real-time theory and practical implementation of real-time scheduling algorithms on General Purpose Operating Systems, with a special focus on Linux. At the moment, he works at ARM Ltd., where he continues contributing to the Linux scheduler development.
