What’s so fun about the Linux Scheduler? and why you might want to start playing this game

Speaker : Juri Lelli

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!
