SANT’ANNA SCHOOL HOSTS THE LINUX KERNEL OSPM SUMMIT VIRTUAL EXPERIENCE ON “SCHEDULING AND POWER MANAGEMENT”, PISA, MAY 11 – 19, 2020

Due to the COVID-19 pandemic, the Sant’Anna School research community decided to move online the conference Scheduling and Power Management for the Linux Kernel: OSPM Summit 2020 on May 11-19.  The  Linux Kernel OSPM Summit 2020 was planned to take place in the TeCIP Institute but in the interest of  the scientific community and attendees this online event will provide an opportunity to hear from ARM, RedHat, Intel, Google, VMWare, Oracle, Linaro, SuSE and IBM experts and keynote speakers.

The conference organizers Tommaso Cucinotta and Luca Abeni, professors of Embedded Systems at the TeCIP Institute RETIS Lab., embraced the opportunity to connect with Juri Lelli (RedHat), Morten Rasmussen (ARM) and Claudio Scordino (Evidence s.r.l.) for covering the latest developments to the power management and scheduling facilities for the energy harvesting embedded systems in the Linux Kernel and other related topics such as real-time performance requirements, energy consumption, and heterogeneous mobile platforms future releases.

The OSPM Summit 2020 will cover: 

·         Performance or Security, hardware problems and CPU optimization: Meltdown, Spectre and L1TF vulnerabilities.

·         Thermal pressure, overheating events, and thermal management on mobile devices.

·         Developments of ARM’s Big.Little multi-core load balancing architecture for power/performance optimization.

·         The API of co-kernel approaches, system performance and the latency effects of real-time applications.

·         The Virtual Machine Power Management on Cloud Computing.

The Linux Kernel is the largest software project on the planet, with over 21 million lines of code. It is a complex ecosystem with numerous areas of specialty. The kernel covers many areas, from hardware enablement to scheduling algorithms for new generation of robotic workstations in manufacturing industry, embedded systems, and the combination of data analytics with high performance computing configurations.

The RETIS Lab. participates in the Linux open source ecosystem under the EU ACTORS project and in cooperation with Italian company Evidence. Researchers of RETIS Lab have developed the SCHED_DEADLINE scheduler available in the Linux kernel since version 3.14. The SCHED_DEADLINE scheduler is suitable for real-time applications like multimedia and industrial control. Based on scheduling algorithms, so that latencies are bounded, and timing constraints are guaranteed, it allows specifying the timing constraints of each running task.

The OSPM Summit will provide a great opportunity to discuss the Kernel state of the art and plans to reduce energy consumption allowing a rigorous comparison of existing features with the effectiveness of hybrid architectures.
