Workshop Description

Critical real-time systems have timing requirements in addition to functional requirements. Most real-time critical systems are moving towards multi-core architectures, on which several programs may execute at once and access the same resources (bus, memory, peripherals). Existing work about analysis of multi-core systems rely on the timing compositionality assumption : the worst case behavior of a system can be obtained by the worst case of its components and of interferences. Nevertheless, some sources of interference may reduce the overall execution time, even though they locally increase it. This phenomenon is called a timing anomaly.

This workshop aims at gathering various research groups working on timing anomalies, in order to standardize the existing definitions and classifications of timing anomalies, explore research directions to mitigates their effects or avoid them entirely.
