1st workshop on Real-Time Mixed Criticality Systems

NEW: Workshop Program

held in conjunction with the

RTCSA’2013: the 19th IEEE International Conference on Embedded and Real-Time Computing Systems and Applications

August 21st, Taipei, Taiwan

The 1st workshop on Real-Time Mixed Criticality Systems (ReTiMiCS 2013) will be a workshop to discuss real-time mixed criticality systems with one keynote and thematic sessions. The format of this workshop encourages interaction between participants to promote a spirit of co-operation and collaboration within the real-time scheduling community.

Mixed Criticality Systems (MiCS) are new systems trying to combine safety-critical and consumer systems on the same platform. Consumer market redefines embedded systems and is source of hardware evolutions (multi-core, many-core systems, distributed). Safety-critical systems (automotive, aerospace) should take advantage of those new platforms to produce robust and predictable systems at competitive price. Safety-critical and consumer application are usually run on distinct systems. Research on Mixed-Criticality Systems aims at closing the gap between those two systems.

Research challenges for MiCS are numerous. Among them, this workshop invites submissions in the areas such as, but not limited to:

  • Integration of critical and non critical applications on real-time multiprocessor systems. New concepts for hardware/software architectures (hypervisor, operating systems, schedulability conditions, formal methods, …)

  • High performance computing with MiCs. By-pass Moore’s law by handling power consumption, heat dissipation limitations. Cache scheduling and related issues (CRPD), parallel scheduling, 3D architectures.

  • Security and dependability issues with MiCS. How to conceive systems of different criticality having to cooperate ?

  • Application of MiCS to new domains: mobile telecommunication networks, energy management systems,…

  • Data Management in shared memory used for critical and non critical applications at the same time.

"Scheduling Theory for Mixed-Criticality Systems:"

In the context of computer systems, scheduling theory is concerned with the efficient allocation of limited computational resources amongst competing demands, in order to optimize specified system-wide objectives. In this presentation we will examine how real-time scheduling theory has adapted to deal with the recent trend towards implementing functionalities of different levels of importance, or criticalities, upon a shared platform. We will explore the factors that motivated this trend towards mixed-criticality (MC) systems, discuss how these MC systems pose unique challenges to real-time scheduling theory, describe how real-time scheduling theory is beginning to respond to these challenges by devising new models and methods for the design and analysis of MC systems, and enumerate some of the many important open issues that remain to be dealt with.
