Abstract
In the last decade, there has been a growing interest in applying AI technologies to implement complex data analytics over data streams. To this end, researchers in various fields have been organising a yearly event called the "Stream Reasoning Workshop" to share perspectives, challenges, and experiences around this topic. In this paper, the previous organisers of the workshops and other community members provide a summary of the main research results that have been discussed during the first six editions of the event. These results can be categorised into four main research areas: The first is concerned with the technological challenges related to handling large data streams. The second area aims at adapting and extending existing semantic technologies to data streams. The third and fourth areas focus on how to implement reasoning techniques, either considering deductive or inductive techniques, to extract new and valuable knowledge from the data in the stream. This summary is written not only to provide a crystallisation of the field, but also to point out distinctive traits of the stream reasoning community. Moreover, it also provides a foundation for future research by enumerating a list of use cases and open challenges, to stimulate others to join this exciting research area.

IRQ Coloring: Mitigating Interrupt-Generated Interference on ARM Multicore Platforms

Authors: Diogo Costa, Luca Cuomo, Daniel Oliveira, Ida Maria Savino, Bruno Morelli, José Martins, Fabrizio Tronci, Alessandro Biasci, and Sandro Pinto

Published in: OASIcs, Volume 108, Fourth Workshop on Next Generation Real-Time Embedded Systems (NG-RES 2023)

Abstract
Mixed-criticality systems, which consolidate workloads with different criticalities, must comply with stringent spatial and temporal isolation requirements imposed by safety-critical standards (e.g., ISO26262). This, per se, has proven to be a challenge with the advent of multicore platforms due to the inner interference created by multiple subsystems while disputing access to shared resources. With this work, we pioneer the concept of Interrupt (IRQ) coloring as a novel mechanism to minimize the interference created by co-existing interrupt-driven workloads. The main idea consists of selectively deactivating specific ("colored") interrupts if the QoS of critical workloads (e.g., Virtual Machines) drops below a well-defined threshold. The IRQ Coloring approach encompasses two artifacts, i.e., the IRQ Coloring Design-Time Tool (IRQ DTT) and the IRQ Coloring Run-Time Mechanism (IRQ RTM). In this paper, we focus on presenting the conceptual IRQ coloring design, describing the first prototype of the IRQ RTM on Bao hypervisor, and providing initial evidence about the effectiveness of the proposed approach on a synthetic use case.
