Outstanding Paper Award at ECRTS 2018

6, Jul, 2018

A CISTER squad (Geoffrey Nelissen; Patrick M. Yomsi; Konstantinos Bletsas; Muhammad A. Awan; Miguel G. Gaitán and Mubarak Ojewale) led by the CISTER Director Eduardo Tovar splashed the 30th Euromicro Conference on Real-Time Systems (ECRTS 2018) in Barcelona, Spain. ECRTS is the premier European venue for presenting research into the broad area of real-time systems and ranks as one of the top three international conferences on this topic. Geoffrey Nelissen and Patrick M. Yomsi were part of the Technical Program Committee and the other members of the squad presented papers at the main conference and/or satellite events. Noteworthily, the paper titled "On Strong and Weak Sustainability, with an Application to Self-Suspending Real-Time Tasks", co-authored by Felipe Cerqueira and Björn Brandenburg from the Max Planck Institute for Software Systems (MPI-SWS) in Kaiserslautern, Germany and Geoffrey Nelissen, was awarded the Outstanding Paper Award.

The Outstanding Paper Award abstract is as follows: In the real-time research community, a scheduling policy and/or a schedulability test for a scheduling policy is said to be sustainable if any system deemed schedulable by the schedulability test remains schedulable when the parameters of one or more individual tasks are changed in any, some, or all of the following ways: (i) decreased execution requirements; (ii) larger periods; (iii) smaller jitter; and (iv) larger relative deadlines. In this paper, motivated by an apparent contradiction regarding whether certain scheduling policies are sustainable, the authors revisited the topic and argued that the existing definitions of sustainability should be further clarified and generalized.
