Optimizing Per-Core Priorities to Minimize End-To-End Latencies

Authors: Francesco Paladino, Alessandro Biondi, Enrico Bini, and Paolo Pazzaglia

Published in: LIPIcs, Volume 298, 36th Euromicro Conference on Real-Time Systems (ECRTS 2024)

Abstract

Logical Execution Time (LET) allows decoupling the schedule of real-time periodic tasks from their communication, with the advantage of isolating the communication pattern from the variability of the schedule. However, when such tasks are organized in chains, the usage of LET at the task level does not necessarily transfer the same LET properties to the chain level. In this paper, we extend a LET-like model from tasks to chains spanning over multiple cores. We leverage the designed constant latency chains to optimize per-core priority assignment. Finally, we also provide a set of heuristic algorithms, that are compared in a large-scale experimental evaluation.

04491 Abstracts Collection – Synchronous Programming - SYNCHRON'04

Authors: Stephen A. Edwards, Nicholas Halbwachs, Reinhard von Hanxleden, and Thomas Stauner

Published in: Dagstuhl Seminar Proceedings, Volume 4491, Synchronous Programming - SYNCHRON'04 (2005)

Abstract

From 28.11.04 to 03.12.04, the Dagstuhl Seminar Perspectives Workshop 04491 ``Synchronous Programming - SYNCHRON'04'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

04491 Executive Summary – Synchronous Programming - SYNCHRON'04

Authors: Stephen A. Edwards, Nicholas Halbwachs, Reinhard von Hanxleden, and Thomas Stauner

Published in: Dagstuhl Seminar Proceedings, Volume 4491, Synchronous Programming - SYNCHRON'04 (2005)

Abstract

This seminar was the 11th in a series of semi-annual workshops on the Synchronous Languages (Esterel, Lustre, and Signal). These languages were invented in the early 1980's to make the programming of reactive systems easier. The goal of the seminar was to bring together researchers and practitioners of synchronous programming, and furthermore to reach out to relevant related areas and industrial users.
